Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 1-1 CTO 0030 1.0 INTRODUCTION Tetra Tech, Inc. (Tetra Tech) ha s been contracted by the Departmen t of the Navy, Naval Facilities Engineering Command Southeast (NAVFAC SE) to perform a Five-Year Review for Naval Air Station (NAS) Pensacola located in Pensacola, Florida. The Five-Year Review includes seven Operable Units (OUs) at the facility. The purpose of this Five-Year Review is to det ermine whether the remedies at the seven OUs are protective of human health and the environment. The methods, findings, and conclusions of the Five-Year Review are documented in this report. In addition, this report identifies issues, if any, found during the Five-Year Review, and presents recommendations to address them. 1.1 FIVE-YEAR REVIEW PROCESS This Five-Year Review was prepared pursuant to the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) 121 and the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). CERCLA 121 states: If the President selects a remedial action that results in any hazardous substances, pollutants, or contaminants remaining at the site, the Pres ident shall review such remedial action no less often than each five years after the initiation of such remedial action to assure that human health and the environments are being protected by the remedial action being implemented. In addition, if upon such review it is the judgment of the President that action is appropriate at such site in accordance with section [104] or [106], t he President shall take or require such action. The President shall report to the Congress a list of facilities for which such review is required, the results of all such reviews, and any actions taken as a result of such reviews. This requirement is further interpreted in t he NCP; 40 Code of Federal Regulations (CFR) 300.430(f)(4)(ii) states: If a remedial action is selected that results in hazardous substances, pollutants, or contaminants remaining at the site above levels that allow for unlimited use and unrestricted exposure, the lead agency shall review such action no less often than every five years after the initiation of the selected remedial action. For federal facility sites under the ju risdiction, custody, or control of the Department of Defense, Executive Order 12580 delegates the responsibility for Five Year Review Completion per CERCLA 121 to the

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 1-2 CTO 0030 Department of Defense. The Navy is the lead agenc y responsible for this Five-Year Review at NAS Pensacola, working with the United States Enviro nmental Protection Agency (USEPA) and the Florida Department of Environmental Protection (FDEP) through the Federal Facility Agreement (FFA) signed October 23, 1990. 1.1.1 Administrative Components The first Five-Year Review was conducted because hazardous substances, pollutants, and contaminants from past storage, handling, and disposal practices at OU1 and OU10 remained at concentrations above levels that allow for unlimited use (UU) and unrestricted exposure (UE) at NAS Pensacola. The first FiveYear Review only addressed OU1 and OU10 and was prepared in February 2003. The second Five-Year Review addressed OU1, OU4, OU11, and OU13 and was completed and signed by the Navy on August 22, 2008. OU10 was not included in the second Five-Year Review because the site was transferred to the RCRA Program. This is the third Five-Year Review for NAS Pensacola, and consists of reviews of the previous Five-Year Review; evaluation of the issues raised in the pr evious review, actions taken, and results; site inspections; personnel interviews; and a technica l assessment of each site and the remedial actions underway. This Five-Year Review addresses OU1, OU2, OU3, OU4, OU11, OU13, and OU18, all of which now have signed Record of Decisions (RODs) in place. This Five-Year Review is being conducted because hazardous substances, pollutants, and cont aminants from past storage, handling, and disposal practices remain at levels that do not allo w for UU and UE at these specific sites. This third Five-Year Review was initiated with a scoping teleconference on April 11, 2012 and preparation of the draft Five-Year Review document. The Navy co mpleted the draft document and submitted it to the regulatory agencies in October 2012. It is expected that the draft final document will be submitted in July 2013 and final document submitted in August 2013. Sections 2.0 through 8.0 of this report are the FiveYear Reviews for OU1, OU2, OU3, OU4, OU11, OU13, and OU18, respectively. Each section includes the sites chronology; background and summary of the remedial actions performed; and the Five-Year Review findings, assessment, deficiency list, reco mmendations, and protectivene ss statements. Section 9.0 provides a general summary, conclusions, and pr otectiveness statement for the OUs reviewed at NAS Pensacola. Figure 1-1 shows the location of NAS Pensacola, and Figure 1-2 shows the location of the OUs included in the Five-Year Review.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 1-5 CTO 0030 Tetra Tech conducted this Five-Year Review in conjunction with the NAS Pensacola Partnering Team, which consists of the following personnel: Patty Marajh-Whittemore, NAVFAC SE Greg Campbell, NAS Pensacola Public Works Department Tim Woolheater, USEPA David Grabka, FDEP Gerald Walker, Tetra Tech Allison Harris Resolutions Brian Caldwell, Resolutions Sam Naik, CH2M HILL 1.1.2 Community Involvement A public notice of announcing the initiation of this Five-Year Review was published in the Pensacola News Journal on (date). At the conclusion of the review, a fact sheet is planned for production and distribution to the Restoration Advisory Board a nd any other interested persons or organizations. 1.2 OVERVIEW OF NAS PENSACOLA The official mission of NAS Pensacola is to provide facilities, service, and support for the operation and maintenance of naval weapons and aircraft to operating forces of the Navy as designated by the Chief of Naval Operations. Some of the tasks required to accomplish this mission include operation of fuel storage facilities, performance of aircraft maint enance, maintenance and operation of engine repair facilities and test cells for aircraft engines, and support of weapon systems. The following sections provide a history and chronology, as well as a brief description of the physical and geological conditions at NAS Pensacola. 1.2.1 History and Site Chronology The U.S. Navy has maintained a presence in the Pensacola area since 1825, when a Navy Yard was established on Pensacola Bay. Between 1828 and 1835, the Navy acquired a pproximately 2,300 acres as operations expanded. Several natural disasters in the early 1900s destroyed the yard and forced it into maintenance status in 1911. Three years later the Navy's first permanent air station was established on the site of the old Navy yard. The air station has been the primary training base for naval aviators since that time and continues to expand (EnSafe, 1996a).

PAGE 25

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 1-6 CTO 0030 The Navy initiated an environmental investigation of NAS Pensacola in 1983. Because of environmental investigation activities, 29 potential sources of contamination (PSCs) were identified as needing additional investigation. In December 1989, the base was plac ed on the National Priorities List (NPL). The FFA, signed in October 1990, outlined the regulatory path to be followed at NAS Pensacola. NAS Pensacola must complete not only the regulatory obligations associ ated with its NPL listing, but it also must satisfy the ongoing requirement of an environmental Resource Conservation and Recovery Act (RCRA) permit issued in 1988. The RCRA permit is an authorizi ng document issued by the FDEP, as authorized by USEPA, to implement the requirements of hazardous waste ma nagement and environmental regulation. That RCRA permit addresses the treatment, storage, and disposal of hazardous waste, and the investigation and remediation of any releases of hazardous waste an d/or constituents from Solid Waste Management Units at NAS Pensacola. The RCRA pe rmit also governs ongoing use of hazardous wastes and the operating permit rules. RCRA and CERCLA investigatio ns and actions are coordinated through the FFA, streamlining the cleanup process. Currently, the cleanup program is being conducted under the Navy's Installation Restoration (IR) program. A Post Closure RCRA Permit Renewal application for NAS Pensacola was submitted to the FDEP in March 2006. Amendments to the original RCRA permit application were submitted in January 2007 and the RCRA Permit Renewal (Permit Number 01544 98-005-HF) was completed in September 2008. 1.2.2 Land Use Today, NAS Pensacola occupies 5,800 acres on a penins ula in southern Escambia County, five miles southwest of the city of Pensacola. The peninsul a is bounded on the north by Bayou Grande and on the east and south by Pensacola Bay. Various housing, training, and support facilities are on the base. A large Naval Aviation Depot (NADEP) that repairs and refurbishes aircraft engines and frames was in the area surrounding Chevalier Field. Most industrial o perations were conducted in the older portion of the base, which is at the eastern end of the peninsula. The NADEP was decommissioned in September 1995. The western end is taken up by t he main airfield (Forrest Sherman Field) and undeveloped forest land (EnSafe, 1996a). 1.2.3 Physiography and Topography NAS Pensacola is located in the extreme southeastern portion of Escambia County, Florida, which lies within the Coastal Plain Province of the United Stat es. As described in the Initial Assessment of NAS Pensacola (NEESA, 1983), NAS Pensacola lies within the coastal lowland that is characterized by a series of broad, nearly level marine terraces that ex tend several miles from the coast and merge with the

PAGE 26

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 1-7 CTO 0030 narrow terraces along the Escambia and Perdido Rivers. NAS Pensacola is located on a peninsula with gently sloping terrain. The land surface elevations on the peninsula range from sea level to approximately 40 feet above mean sea level. 1.2.4 Climate Escambia County has a warm, humid-temperate climate (USDA, 2004). Along the coast, the Gulf of Mexico moderates high temperatures in the summer and low temperatures in the winter. Total annual precipitation is about 62 inches. The greatest amount of rain falls in July and August. Occasionally, short droughts occur in late spring. 1.2.5 Soil Soil at NAS Pensacola developed in marine terrace sedi ment deposits and is regi onally classified by the United States Department of Agriculture (USDA), Soil Conservation Service as the Pelham-Mascotte-Sapelo soil series assocation. Soils in this association are characterized as nearly level, poorly drained sands to a depth of 20 inches below land surface (bls), which are underlain by loamy sands (USDA, 2004). 1.2.6 Regional Geology The surficial geology of the area consists of Pleistocene marine deposits made up of light brown to tan, fine quartz sand with associated stringers and lenses of gravel and clay. Underlying these deposits, increasing with age, are the Citronelle Formation, the Miocene Coarse Clastics, the Pensacola Clay, the Tampa Formation, the Chickasawhay Limestone, the Bucatunna Clay member of the Byram Formation, the Ocala Group, the Lisbon equivalent, the Tallahatta Formation, and the Hatchetigbee Formation. The Pleistocene deposits and Citronelle formation are oft en impossible to differentiate, and together range in thickness from approximately 30 feet to 800 feet across Escambia County (NEESA, 1983). 1.2.7 Regional Hydrology 1.2.7.1 Surface Water NAS Pensacola is bordered on the south by Big Lagoon, on the south and east by Pensacola Bay, and on the north by Bayou Grande (NEESA, 1983). Sandy surface soil in this area allows for a high proportion of rainfall to infiltrate into the ground and consequently there are few streams. The surface topography has little dissection and the natural drainage system is poorly developed. Much of the surface drainage has been constructed or modified to accommodat e structures on base. Swampy areas exist at or near the western portion of NAS Pensacola, and man-made drainage ways and storm drains feed into

PAGE 27

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 1-8 CTO 0030 the short intermittent streams that empty into Pens acola Bay and Bayou Grande. Perennial streams do not enter or exit NAS Pensacola, but marshy ar eas and three small lakes on the golf course are persistent throughout the year. 1.2.7.2 Groundwater Groundwater in Escambia county occurs in three major aquifers: a shallow aquifer which is both artesian and non-artesian (the sand and gravel aquifer), and two deep artesian aquifers (the upper and lower limestone of the Floridan aquifer). In the southern half of the area, the sand and gravel aquifer and the upper limestone of the Floridan aquifer are separated by a thick section of relatively impermeable clay; but, in the northern half of the area the sand and gr avel aquifer and the upper limestone of the Floridan aquifer are in contact with one another. The upper limest one of the Floridan aquifer is separated from the lower limestone by a thick clay bed (NEESA, 1983). The sand and gravel aquifer is composed of sand but has numerous lenses and layers of clay and gravel. The formation also contains lenses of hardpan where the sand has been cemented by iron oxide minerals. This aquifer lies at the surface throug hout Escambia County. Boring logs from various locations at NAS Pensacola show that the surficia l sands extend from ground surface to a depth of approximately 35 feet mean sea level below (approximate ly 50 feet bls) which is a 15-foot thick marine clay, the continuity of which is uncertain. Underlying the clay is more sand with numerous clay lenses (Geraghty and Miller, 1986). Groundwater levels in the shallow aquifer range from just below the land surface to approximately 30 feet bls across the NAS Pensacola area. The groundwater flow across the NAS Pensacola peninsula area has historically been found to be toward the Gulf of Mexico and the Escambia and Perdido rivers, although groundwater flow can vary locally to drainage features, water bodies and wetlands due to the effect of topography. The aquifer recharge is pre dominantly from precipitation (Geraghty and Miller, 1986). The shallow saturated permeable beds in the sand and gravel aquifer contain groundwater under nonartesian (non-confined) conditions, while the deep er permeable beds contain groundwater under artesian pressure, where they are confined by lenses of clay and sandy clay (NEESA, 1983). Below the sand and gravel aquifer, the limestone la yers comprise the regionally extensive Floridan aquifer, which in this area is divided into upper and lower units separated by the Bucatunna clay. The upper Floridan aquifer is an important source of water in areas east of Escambia County; however, in the Pensacola area it is highly mineraliz ed and not used as a water supply. The lower Floridan aquifer is also

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 1-9 CTO 0030 highly mineralized and is designated for use as an inje ction zone for waste disposal in this area (Geraghty and Miller, 1986). 1.3 ARAR CHANGES AND SITE-SPEC IFIC ACTION LEVEL CHANGES The Applicable or Relevant and Appropriate Requirem ents (ARARs) identified in each of the RODs were reviewed to determine if they had been updated sinc e the last Five-Year Review. An evaluation of chemical, action, and location ARARs was conducted as appropriate for each OU. These evaluations are addressed specifically in each OU review section. 1.4 NEXT REVIEW The next Five-Year Review for NAS Pensacola will be completed no later than five years from the date of this review.

The implementation of the rem edial actions at OU1, began in 1999. The initial Five-Year Review for OU1, an inactive sanitary landfill al so referred to as Site 1, was completed in 2003. This Five-Year Review consists of an approximate fi ve-year period of data a nd provides a status update for OU1. This statutory review is required because hazardous substances, pollutants, or contaminants remain at the site above levels that allo w for unlimited use and unrestricted exposure. 2.1 SITE CHRONOLOGY Historical events and relevant dates in the OU1 chronology are summarized in Table 2-1.

The landfill surface varies from 8 to 20 feet above mean sea level and is densely vegetated with 15 to 40-foot tall planted pines and natural sc rub vegetation. The landfill is bordered by an inland water body (Bayou Grande) to the north, by the A.C. Read Golf Course to the east, and by areas of natural scrub vegetation and Barrancas National Cemetery to the west and south. Bayou Grande has been classified by the FDEP as a Class III Predominant ly Marine water body, indicating its use for recreation and maintaining a well-balanced fish and wildlife population. Beyond the scrub vegetation, Taylor Road lies approximately 200 feet south of the site. 2.2.2 Land and Resource Use at OU1 From the early 1950s until 1976, domestic and industrial wastes from NAS Pensacola and other outlying Navy facilities were disposed at OU 1. Industrial wastes consist ed of ketone, polychlorinated biphenyl (PCB), and transformer oil-soaked ra gs; paint chips; paint sludge; compressed air cylinders; asbestos; and garbage. The facility was officially closed on October 1, 1976 (EnSafe, 1998). The land use for the areas immediately north of th e landfill include a Boy Scout camp, a nature trail, a picnic area, and recreational Buildings 3553 and 3487. Also in this general area are two tidal-inlet ponds with associated wetlands. Other wetland areas are located to the west and east of the landfill; most are associated with marshy intermittent creeks. On May 23, 2002, 49.83 acres of uplands located immediately adjacent to the south and southwest portion of OU1 was transferred to the Veterans Administ ration (VA). This purpose of this transfer was to provide for expansion of the Barrancas Military Cemetery and construction of an administration building, and a facility maintenance building. The nearest residential area (base housing) is approxi mately 1,000 feet south of OU1. Potable water for this residential area and all of NAS Pensacola is supplied from Corry Station, approximately three miles north of NAS Pensacola. Groundwater flow is generally northward, toward Bayou Grande and adjacent surface water features, with components to the northwest and northeast (EnSafe, 1998).

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 2-5 CTO 0030 2.3 HISTORY OF CONTAMINATION AT OU1 Landfill leachate was discovered in 1974 to be discharging from an abandoned drainage field into a nearby golf course pond. Groundwater samples from this area were found to contain phenol and several metals. Additional groundwater investigations (V erification and Confirmation Studies) indicated the presence of volatile organic compounds (VOCs) and trace concentrations of semivolatile organic compounds (SVOCs). It was determ ined that groundwater contamination by VOCs, SVOCs, and metals exceeded federal and state regulatory criteria and wa s limited to the areas within and around the landfill perimeter. However, several metals were determi ned to be leaching from site soils to the shallow groundwater and migrating to Wetland 3. Also, a tar pit was identified during the RI, which posed a physical hazard to site trespassers (EnSafe, 1998). 2.3.1 Initial Response for OU1 The physical hazard presented by the tar pit was initia lly addressed. Analytical results from the Toxicity Characteristic Leaching Procedure (TCLP) of samples collected from the tar pit in 1993 indicate that the tar was not considered a hazardous waste. A total of 73 tons of tar was excavated in January 1998 to remove the physical hazard and potential for release of chemicals to the environ ment and disposed at an off-site Subtitle D landfill. 2.3.2 Basis for Taking Action at OU1 A Remedial Investigation (RI) was completed for OU 1 in January 1996. Contaminants were detected in groundwater at concentrations that could cause unac ceptable risk for future residents at OU1. Contaminants of concern (COCs) are summarized in Table 2-2. TABLE 2-2 OU1 CONTAMINANTS OF CONCERN FIVE-YEAR REVIEW NAVAL AIR STATION PENSACOLA PENSACOLA, FLORIDA Medium Contaminants Causing Unacceptable Risk Groundwater Arsenic, barium, cadmium, manganese, nickel, vinyl chloride, benzene, chlorobenzene, and chloroform During the human health risk assessment (HHRA) it was determined that exposure to chemicals of potential concern (COPCs) in surface and subsur face soil and groundwa ter was within USEPAs generally acceptable ranges for the trespassing child and the potential future site worker. However, exposure to COCs in the shallow/intermediate and deep groundwater (Table 2-2) presented an

PAGE 34

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 2-6 CTO 0030 unacceptable risk via the ingestion and inhalation exposure pathways for the hypothetical future site resident. Unacceptable risk was not determined for exposure by current and future site residents, workers, and trespassers to the surface and subsurface soil (EnSafe, 1998). Ecological risks were determined to be inconsequential for flora and fauna from the ecological contaminants of potential concern (ECOPCs) in so il. Other than Wetland 3, appreciable ecological effects were not expected from the groundwater that was discharging to wetlands. The risk to ecological receptors at Wetland 3 was evaluated by comparing the concentrations of ECOPCs detected in sediment and surface water samples to est ablished screening values from FD EP and USEPA Region 4 guidance. Based on the evaluation of the ECOPCs, the OU1 ec ological COCs included metals and pesticides. Benthic community species and fish in downgradi ent sections of the wetland were determined to be potentially exposed to an unacceptable excess risk. Methods proposed to assess potential unacceptable risk to receptors for Phase IIB of the Site 41 RI were bioassays for benthic and fish species. Bayou Grande (Site 40) and NAS Pensacola wetlands were to be evaluated in the RI for Site 41. 2.4 REMEDIAL ACTION 2.4.1 Remedy Selection at OU1 The ROD for NAS Pensacola OU1 was finalized on September 25, 1998. Remedial Action Objectives (RAOs) were developed as a result of data collected during the RI to aid in the development and screening of remedial alternativ es to be considered for the ROD. The purpose of the remedial action at OU1 was to reduce the unacceptable risks to human health and environment associated with exposure to COCs in groundwater and surface water and protect groundwater from the leaching of wa ste in the landfill from soil to gr oundwater. To m eet these goals, three RAOs were identified. Tabl e 2-3 lists the RAOs for OU1.

Of the four alternatives evaluated, the selected remedial action for OU1 was Alternative 2C as described in the ROD for OU1. The major components of Alternative 2C are listed below: Institutional controls imposed to restrict groundwater use of t he surficial zone of the sand and gravel aquifer within 300 feet of the site. Institutional controls imposed to limit intrusive activities within the landfill boundary without prior approval from the NAS Pensacola Environmental Office. Annual review of the institutional controls and cert ification that the controls should remain in place or be modified to reflect changing site conditions. Groundwater monitoring to ensure that the natural attenuation processes are effective. A review during which the Navy would determi ne whether groundwater performance standards continue to be appropriate and if natural attenuation processes are effective. Continued groundwater monitoring at regular samp ling intervals after performance standards are attained. The groundwater monitoring program would continue until a Five-Year Review concludes that the alternative has achieved cont inued attainment of the performance standards and remains protective of human health and the environment.

The intercepted groundwater will be treated to reduce iron levels before being reintroduced into Wetland 3. Concentrations of the organic compounds pres ent in the groundwater and surface water will be reduced through natural attenuation resulting from naturally occurring biotic and abiotic processes, which take place in the groundwater and surface water systems. 2.4.2 Remedy Implementation at OU1 The remedial action was organized into two phases. The first phase included the design and construction of the treatment system. The second phase included the long-term groundwater monitoring plan. The remedial action selected for implementation at OU1 is consistent with CERCLA and the NCP. The final Remedial Design was prepared by Bech tel Environmental, Inc. (BEI) and was included as a component of the Remediation Work Plan/Remedial Design for Phase I Groundwater Treatment and Recovery System at Operable Unit 1 (BEI, 1999a). BEI initiated remedial activities on March 12, 1999 and completed the installation of the groundwater inte rception system, on May 7, 1999. The installation of electrical utilities, system st artup, and performance monitoring we re performed during the period of June 8 through June 17, 1999. The Long-term Groundwater Monitoring Plan for Phase II Remedial Action was issued by BEI in July 1999. The long -term monitoring (LTM) program included groundwater monitoring, Monitored Natural Attenuation (MNA), and surface water sampling two times per year for years one through three, then annua lly until the COCs are below performance standards (BEI, 1999b). Additional remedial construction activities were completed when t he UFP-SAP was updated in July 2010 and approved in November 2010. The updated UFP-SAP provided for installation of six new groundwater monitoring wells (four replacement and two new monito ring wells), and monitoring of the new wells, eight piezometers/staff gauges, 11 existing monitoring wells, and three surface water sampling locations (Tetra Tech, 2010). Groundwater samples are analyzed for VOCs and metals, and surface water samples are analyzed for total iron as specified in the ROD (EnSafe, 1998). 2.4.3 Land Use Restriction Agreement As specified in the final ROD for OU1 (EnSafe, 1998), the institutional controls for OU1 are imposed using a Land Use Restriction Agreement (LURA). The LURA wa s actually completed in the form of a MOA as agreed by the USEPA, FDEP, and the Navy, and signed on September 24, 1999.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 2-9 CTO 0030 Attached as an appendix to the MOA is a Land Use Control Implementation Plan (LUCIP) for OU1, which provides the site description, site location, LUC objectives, LUC implementation to achieve objectives, and the reference decision document. The LUCIP specified: The NAS Pensacola IR Manager shall be responsibl e and coordinate inspections of this site. Any discrepancies will be forw arded to NAS Pensacola Facilities Offi cer for correction to maintain the objectives. Institutional controls shall be imposed to restrict groundwater use of the surficial zone of the sand and gravel aquifer within 300 feet of the site boundaries. No intrusive activities shall be permitted within the site boundaries without prior approval from the NAS Pensacola Environmental Office. The NAS Pensacola IR Manager will submit an annual review of the in stitutional controls and certification that the controls should remain in place or be modified to reflect changing site conditions. Groundwater shall be monitored down gradient of the site to ensure natural attenuation processes are effective and contaminants above state and federal levels are not being discharged into adjacent surface waters. The groundwater interception system installed to capture contaminated groundwater upgradient of Wetland 3 will continue operation wi th the effluent being treated prior to being discharged and shall be maintained until performance standards that are acceptable to both FDEP and USEPA are achieved. The groundwater moni toring program will cont inue until a Five-Year Review concludes that the alternative has achi eved continued attainment of the performance standards and remains protective of human health and the environment. 2.4.4 System Operation/Operation and Maintenance at OU1 The Navy operated the groundwater interception system from June 1999 until May 2010. The effectiveness of the groundwater interception system was evaluated during an Optimization Study, a Five-Year Review, and Reconnaissance Phase Flow Control Pilot Study as discussed below. 2007 Optimization Study: The Optimization Study found that although the groundwater interception system could contribute to reducing some iron conc entrations within shallow groundwater, surface water data indicated that the groundwater interception system was not having an appreciable effect on the overall iron concentrations in surface water within We tland 3 because of the prevalence of iron within the shallow groundwater upgradient, side-gradient, and downgradient to the groundwater interception system. Furthermore, the Optimization Study found t hat attenuation of iron is naturally occurring in Wetland 3. The mechanisms by which this is oc curring are believed to be physical, chemical, and biological. Based upon field observations, physical processes including natural sedimentation appear to be occurring where the iron flocculent is dropping out of suspension.

PAGE 38

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 2-10 CTO 0030 Additionally, field observations indi cated that vegetation in Wetland 3 appears to be growing with little to no stress. This is a good indication that, as identified in the ROD and documented by the Interstate Technology and Regulatory Council (2003), the native vegetation is likely contribut ing to the reduction of the iron via several mechanisms including sediment ation, adsorption, oxi dation, biological, and phytodegradation of the iron. The vegetation also pr ovides an unspecified amount of evapotranspiration in the wetland which aids in treatment. 2008 Five-year Review: The 2008 Five-year Review found that the concentrations of iron detected in groundwater samples collected from monitoring well s located downgradient from the interceptor trench system (ITS) continue to exceed both the Florida Class III Predominant ly Marine surface water quality criteria of 300 micrograms per liter (g/L) and the ma ximum contaminant level (MCL) for iron of 300 g/L per Chapter 62-550, Florida Administrative Code (F.A.C.), as well as the site-specific background concentration for freshwater wetlands of 2,360 g/L. The Five Year Review concurred with the 2006 Optimization Study and concluded that: performance of the groundwater interception system does not appear to be sufficient to capture and extract the iron contamination migrating to the wetland. Furthermore, even if the groundwater interception system was effectively capturing and treating the local ground water (which it does not appear to do based upon the elevated iron concentrations in groundwater immediat ely downgradient of the groundwater interception system) the prevalence of iron within the sh allow groundwater upgradient, side-gradient, and downgradient to the groundwater interception system would make achievement of the RAOs for surface water in Wetland 3 impractical with the existing system. Reconnaissance Phase Flow Control Pilot Study: The Reconnaissance Phase Flow Control Pilot Study concluded that groundwater cu rrently discharges to surface water in Wetland 3 and that the groundwater-surface water interaction pattern cann ot be changed unless the surface water level is increased to 7.07 feet at the inlet of the culvert. Also, because of the high groundwater elevations southeast of the culvert, it was not clear whether a surface water infiltration area could be created by increasing the surface water elevati on at Wetland 3. The study also determined that due to the relatively low elevation of John Tower Road near the culvert, blocking the culvert would result in flooding over the road and golf course. Therefore, it was recommende d that no further evaluation of flow control be conducted. Additionally, iron background concentrations were u pdated as part of the Re connaissance Phase Flow Control Pilot Study because rather dissimilar pristi ne wetlands (Wetlands 27 and 33) were originally used to establish background values for all wetlands at NAS Pensacola. The iron background concentrations for freshwater and estuarine wetlands were reevaluated because: the original data set

PAGE 39

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 2-11 CTO 0030 was small and non-representat ive, highly variable iron concentrati ons have been detected in the over 80 freshwater and estuarine wetlands at NAS Pensac ola, and many of the wetlands contain iron at naturally occurring concentrations that exceeded the original background value. The new freshwater wetland background threshold was determined to be 4,720 g/L and the new estuarine wetland background threshold was determined to be 5,862 g/L. Also, monitoring on an annual basis at a new monitoring location was implemented because surface water iron concentrations in Wetland 4D are less than or nearly equal to the new estuarine wetland background threshold of 5,862 g/L. The new location was established in Wetland 4D because it receives water from the southwestern side of Wetland 3 and from Wetlands 4A-4B-4C at the southeastern side of Wetland 4D. The new location represents surface water quality in Wetland 4D prior to where it drains to Bayou Grande through a culvert near the northern corner of the wetland. The pointof-compliance location is approxim ately midway between the mixing po int of the two water sources and the culvert. Based on the findings of the Optimization Study, the 2008 Five-Year Review, and a Reconnaissance Phase Flow Control Pilot Study for Wetland 3, ope ration of the groundwater interception system was subsequently discontinued in May 2010. 2.4.5 Long-Term Groundwater Monitoring at OU1 Beginning in December 1999, the Navy initiated the LTM program at OU1. The LTM program semiannual sampling events were conducted between March 2000 and June 2003, but were not conducted from November 2003 through May 2010. LTM and semiannual sampling were not conducted during this period due to extensive hurricane damage throughout the facility. Semiannual sampling events were also not conducted during the Optimization Study and Re connaissance Phase Flow Control Pilot Study. Semiannual sampling was resumed after review and approval of the Data Quality Objectives and UFP-SAP submitted in July 2010 and approved in Nove mber 2010. The semiannual sampling is being conducted as directed by the OU1 ROD, Long-Term Groundwater Monitoring Plan (LTGMP), and the O&M Manual. The completed activities for LTM include: The first year of groundwater and surface wa ter sampling (semiannually), natural attenuation monitoring (semiannually), and annual reporting of results (report dated January 2001). The second year of groundwater and surface wa ter sampling (semiannually), natural attenuation monitoring (semiannually), and annual reporting of results (report dated September 2002).

PAGE 40

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 2-12 CTO 0030 The third year of groundwater and surface wa ter sampling (semiannually), natural attenuation monitoring (semiannually), and annual reporti ng of results (report dated April 2003). The fifth year of groundwater and surface wa ter sampling (semiannually), natural attenuation monitoring (semiannually), and annual reporting of results (report dated December 2006). The sixth year of groundwater and surface water sampling (semiannually), natural attenuation monitoring (semiannually), and annual reporting of results (draft final report dated January 2012). The seventh year of groundwater and surface wa ter sampling (semiannually), natural attenuation monitoring (semiannually), and annual reporting of results (draft report dated March 2012). As stated in the ROD for OU1 (EnSafe, 1998), the Navys original 1996 cost estimate for implementation of remedial action and closure of OU1 and 30 year s of LTM program (risk-reduction) was $4,542,600. The approximate cost to date for remedial actions in cluding O&M and monitoring at OU1 is $1,754,466. 2.5 PROGRESS SINCE THE LAST FIVE-YEAR REVIEW A draft ESD was issued for OU1 on March 30, 2012 to address discontinued operation of the groundwater interceptor trench and make changes to groundwater and surface water monitoring procedures. The 2007 Optimization Study, 2008 Five-Year Review, and 2009 Reconnaissance Phase Flow Control Pilot Study recommend the pumping oper ation of the groundwater interception system be discontinued. Changes to O&M as presented in the ESD include: Sampling and analysis for total iron from two monitoring wells and four piezometers. Monitoring of surface water at Wetland 3 at locations 01SW01 and 01SW02 to verify that discharges from OU1 to Wetland 3 and Wetland 4 do not cause unacceptable impacts to Bayou Grande (a state-classified Class III Predominantly Marine water body). Surface water monitoring location 01SW01 has b een moved approximately 250 feet south of the previous location, and a new surface water monitoring location, 01SW03, has been established in Wetland 4. The surface water RAO for prevention of further contamination of surface water in Wetland 3 is no longer required because iron is not present in surface water in Wetlands 3 at concentrations that appear to adversely affect human health and the environment and that Wetland 3 appears to naturally treat iron.

PAGE 41

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 2-13 CTO 0030 However, based on USEPA comment on the Draft ESD, it is their position that th is RAO is still applicable and should be applied to water discharging from Wetland 3 instead of excluding this RAO altogether as a requirement. 2.5.1 Protectiveness Statements from the Last Review Based on the results of the 2008 Five-Year Review, the remedy was expected to be protective of human health and the environment upon attainment of ground water cleanup goals, through natural attenuation. In the interim, exposure pathways that could resu lt in unacceptable risks were being controlled and institutional controls ar e preventing exposure to, or the inge stion of, contaminated groundwater. Issues identified in the 2008 Five-Year Review, and actions taken are summarized in Table 2-4. TABLE 2-4 OU1 ISSUES IDENTIFIED AND ACTIONS TAKEN 2008 FIVE-YEAR REVIEW NAVAL AIR STATION PENSACOLA PENSACOLA, FLORIDA Issues Identified in 2008 Five-Year Review Actions Taken Since the 2008 Five-Year Review Hydraulically downgradient monitoring wells were destroyed by Hurricane Ivan. The Optimization Study proposes replacement of destroyed wells. Five monitoring wells were installed in 2009. Three of the wells were replacement wells, whereas the remaining two monitoring wells were located hydraulically downgradient. 2.5.2 Status of Recommendations and Follow-up Actions from Last Review Table 2-5 provides a list of recommendations, recommended follow-up actions from the 2008 Five-Year Review, milestone dates, actions taken, outcomes, and dates of action.

In addition, modifications were made to the monitoring program related to the groundwater interception system ITS and Wetl and 3. A draft ESD wa s provided to USEPA and FDEP for review/comment in March 2012 to document these changes. 2.5.2.2 Actions Taken and Outcome for Item 2 from Table 2-5 Monitoring of surface water at Wetland 3 will continue at locations 01SW01 an d 01SW02. Surface water monitoring location 01SW01 has been moved approximat ely 250 feet south of the previous location, and a new surface water monitoring location, 01SW03, has been established in Wetland 4. The surface water RAO for prevention of furt her contamination of surface water in Wetland 3 is no longer required because prevention of groundwater discharge from OU1 to Wetland 3 is not required for protection of human health and the environment. 2.5.2.3 Actions Taken and Outcome for Item 3 from Table 2-5 The Optimization Study proposed replacement of monito ring wells destroyed by Hurricane Ivan. Five monitoring wells were installed in 2009. Three of the monitoring wells were replacement wells, and the other two monitoring wells were new and loca ted hydraulically downgradient of OU1.

Members of the NAS Pensacol a Partnering Team were notified of the initiation of the Five-Year Review in January 2012. The Five-Year Review was led by Gerald Walker of Tetra Tech, the NAVFAC SE Navy CLEAN Contractor, and included other Tetra Tech staff. Patty Marajh-Whittemore of NAVFAC SE, Greg Campbell of NAS P ensacola Public Works Department, Tim Woolheater of U SEPA, David Grabka of FDEP, and Sam Naik of CH2M Hill assisted in the review. The review included the following components: Document Review Data Review Site Inspection Five-Year Review Report development and review 2.6.1 Document Review This Five-Year Review consisted of a review of re levant documents including the RI Report, the FS, the Proposed Plan, the ROD, the Construction Completion Report, the O&M Manual for Groundwater Treatment and Recovery System, the LTGMP, Annual Monitoring Reports, the Optimization Study, the draft ESD, and applicable federal and state statutes. 2.6.2 Data Review 2.6.2.1 Review of COC Data for Groundwater Groundwater monitoring is documented in annual r eports prepared by Tetra Tech in March 2000, January 2001, September 2002, April 2003, December 2006, August 2011 (draft), and July 2012 (draft). Since the initial ROD was signed, six years of semiannual monitoring and sampling have occurred; though the years are not consecutiv e. LTM was not conducted from 2004 to 2005 due to extensive hurricane damage throughout the facility. Later, ground water monitoring was not conducted during the evaluation of the groundwater interc eption system by the Optimization Study (final report Nov 2007) and Reconnaissance Phase Flow Control Pilot Study (completed February 2009). The ROD and LTM Plan (BEI, 1999b) established the groundwater COCs as benzene, chlorobenzene, vinyl chloride, nickel, naphthalene, xylene, 1,1,2, 2-tetrachloroethane, aluminum, cadmium, chromium, iron, and manganese. During the first year of m onitoring xylenes, cadmium, iron, manganese, benzene, vinyl chloride, and chlorobenzene were detected at concentrations exceeding the Cleanup Target

PAGE 44

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 2-16 CTO 0030 Levels (CTLs) established by the ROD. During the second year of monitoring, benzene, vinyl chloride, xylene, aluminum, cadmium, iron, and manganese we re detected at concentrations exceeding their CTLs. During the third year of monitoring, benze ne, chlorobenzene, vinyl chloride, aluminum, iron and manganese were detected above their CTLs. During t he fifth year of monitoring, hydraulic downgradient monitoring wells 01GS57 and 01GS71 were found to be destroyed and could not be sampled. The analysis of groundwater samples collected in J une and December 2005 revealed the presence of seven COCs at concentrations exceeding their respective CTLs. Manganese, aluminum, and iron were the only metals from the COC list with exceedances. Iron and manganese exceedances were distributed evenly across the study area, and four VOCs (ben zene, chlorobenzene, xylene, and vinyl chloride) were detected at concentrations exceedi ng current FDEP criteria. VOC exceedances were limited to monitoring wells located on the perimeter or adjacent to the main body of the old landfill. The groundwater at OU1 was evaluated in light of the changes in the number of monitoring well locations with contaminants that exceed CTLs, and the changes in contaminant concentrations at individual monitoring well locations with time. The trend analysis for the COCs for grou ndwater at NAS Pensacola was performed using the Mann-Kendall test (ProUC L Version 4.1.00 [Lockheed Martin Environmental Services, 2010]) at a 95 percent confidence level a nd groundwater sample data collected from 1993 to 2011. The Mann-Kendall test is used because it does not assume any particular distributional form and accommodates values below the detection limit by assigning them a common value ( the detection limit). Additionally, the 1993 grou ndwater data was collected using bailers; therefore, because the sample turbidity may have biased the analytical dat a, the 1993 data was not used in the Mann-Kendall test for metals. During the May and November 2010 groundwater sampling events, 17 monitoring wells and 8 piezometers were sampled and analyzed for the 12 groundwater COCs. Only seven of the COCs were detected in groundwater samples exceeding their respective Groundwater Cleanup Target Levels (GCTLs). Manganese, aluminum, cadmium, and iron were the only metals that exceeded their CTLs. Based on the locations sampled, alumi num, iron and manganese exceedances appeared to be distributed across the OU1 area. Three VOCs ( benzene, chlorobenzene, and vinyl chloride) were detected at concentrations exceeding their respective CTLs. During the August 2011 groundwater sampling event, 15 monitoring wells and 8 piezometers were sampled and analyzed for the 12 groundwater COCs. During the January 2012 groundwater sampling event, 16 monitoring wells and 8 piezometers were sampled and analyzed for the 12 groundwater COCs. Only six of the COCs were detected in groundwat er samples exceeding their respective CTLs. Manganese, aluminum, and iron were the only metals that exceeded their CTLs. Based on the locations sampled, aluminum, iron, and manganese exceedances appeared to be distributed across the study

PAGE 45

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 2-17 CTO 0030 area. Three VOCs (benzene, chlorobenzene, and vi nyl chloride) were detected at concentrations exceeding their respective CTLs. Comparison of the 2010, 2011, and 2012 groundwater sampling data with previous groundwater sampling data suggests the trends in the COCs concentra tions observed from May 2010to January 2012 are consistent with the long-term concentration trends for most of the monitoring wells. Mann-Kendall Trend analysis results are provided in Appendix A. In general, the test results indicated that for all of the COCs, most monitoring well locati ons demonstrate no significant statistical trend or have a statistically significant downward trend identified, especially for benzene and vinyl chloride. A statistically significant upward trend is identified at a limited number of monitoring well locations for iron, manganese, and/or chlorobenzene. Mann-Kendall Trend analysis data sheets and graphs of the contaminant concentrations versus time are provided in the Appendix A. Three decision rules are used to evaluate the grou ndwater data collected during monitoring events. Decision Rule #1: This rule was established to protect against the potential that analyte concentrations are increasing; even if the analytes' concentrations are less than their applicable Performance Criteria or GCTLs. A significant increasing trend could indi cate that the concentrati ons will eventually become greater than the applicable criteria. Therefore, moni toring should continue for the analyte(s) at any single monitoring well location that has a significant upwa rd trend at a 10 percent significance level. Based on the long-term monitoring data, analytes t hat meet the significant upward trend condition for Decision Rule #1 include: chlorobenzene (4 monitoring well locations), benzene (1 monitoring well location), vinyl chloride (1 monitoring well location), total xylenes (2 monitoring well locations), naphthalene (1 monitoring well location), aluminum (11 monitoring well locations), iron (4 monitoring well locations), cadmium (1 monitoring well location), chromium (7 monitoring well locations), manganese (6 monitoring well locations) and nickel (2 monitoring well locations). Decision Rules #2: This rule was established to de termine if analytes in groundwater are present at concentrations that are less than or equal to their Performance Criteria for two or more consecutive rounds of sampling, and a significant increasing trend is not present as determined by a Mann-Kendall trend test at 10 percent significance, if this condition is met for an analyte at any single monitoring well location, then it is recommended that the monitori ng for that analyte be stopped at that well location; otherwise, it is recommended that monitoring should continue as scheduled.

PAGE 46

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 2-18 CTO 0030 Analytes that meet the condition to discontinue monitoring per Decision Rule #2 include: chlorobenzene (11 monitoring well locations), benzene (8 monitoring well locations), vinyl chloride (11 monitoring well locations), total xylenes (14 monitoring well locations), naphthalene (15 monitoring well locations), aluminum (4 monitoring well locations), iron (2 monitoring well locations), cadmium (14 monitoring well locations), chromium (8 monitoring well locations), manganese (1 monitoring well location) and nickel (13 monitoring well locations). 1,1,2,2-Tetrachl oroethane has not been detected in groundwater samples from shallow and intermediate aquifer zone collected from August 2000 to January 2012. Decision Rules #3: This rule was established to comply with 62-780.690 F.A.C., Contaminated Site Cleanup Criteria Natural Attenuation and Monitoring. This rule determines if analytes in groundwater are present at concentrations less than or equal to the greater of its GCTL and the upgradient concentration for two or more consecutive semiannual (or less frequent) sampling rounds, and the concentration trend is not increasing as determined by a Mann-Kendall trend test at 10 percent significance. If this condition is met for an analyte at any single monitoring well location, then monitoring program for that analyte should be optimized the to reduce the frequency of monitoring; otherwise, it is recommended that monitoring should continue as scheduled. Four of the eight parameters, to tal xylenes, naphthalene, nickel, and chromium, included in the expanded contaminant list in the Proposed Plan have not been detected at concentrations above their GCTLs in the four consecutive sampling events conducted from May 2010 to January 2012. One of the eight parameters, 1,1,2,2-tetrachloroethane included in the expanded contaminant list in the Proposed Plan has not been detected in groundwater samples from shallow and intermediate aquifer zone collected from August 2000 to January 2012. Four of the parameters, total xylenes, naphthalene, nickel, and chromium, had at least one monitoring well location with a significant upward trend (as determined by a Mann-Kendall trend test at 10 percent significance level) in at least one well. 2.6.2.2 Review of Natural Attenuation Data for Groundwater The UFP-SAP for LTM at OU1 (Tetra Tech, 2010) indicates that: Because contaminant monitoring is the primary goal and monitoring is expected to continue fo r a long time, inclusion of these parameters was not considered to be important at this time. As part of the optimization strategy, however, inclusion of natural attenuation parameters to verify or suppor t an evaluation of why the contaminant concentrations are decreasing may be useful and should be considered during the optimization evaluations. In the meantime, groundwater monitoring well stabilization parameters will be collected to support the initial

PAGE 47

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 2-19 CTO 0030 evaluations of natural attenuation. The groundwater well stabilization parameters include: dissolved oxygen (DO), ORP, pH, specific conductance, te mperature, and turbidity by field instrument. Groundwater field parameters that were measured during the August 2011 and January 2012 LTM groundwater sampling events included pH, specific co nductance, turbidity, temperature, dissolved oxygen (DO), and oxidation reduction potential (ORP). ORP values for the shallow aquifer zone monitoring wells sampled during the August 2011 sampling event ranged from -56.5 to 132.7 milliv olts (mV) and for the January 2012 sampling event ranged from -9.9 to 146.8 mV. ORP values for the piezomet ers sampled during the August 2011 sampling event ranged from -149.3 to 27.3 mV and for the January 2 012 sampling event ranged from -125.1 to 65.6 mV. ORP values for the intermediate aquifer zone monitoring wells sampled during the August 2011 sampling event ranged from -183.9 to 154.4 mV and for the J anuary 2012 sampling event ranged from -210.4 to 118.2 mV. The ORP values are generally within a range that suggests that reductive pathways for natural attenuation are possible or likely. DO concentrations for the shallow aquifer zone monitoring wells sampled during the August 2011 sampling event ranged from 0.18 to 1.44 milligrams per liter (mg/L) and for the January 2012 sampling event ranged from 0.26 to 6.73 mg/L. DO concentrations for the piezometers sampled during the August 2011 sampling event ranged from 0.14 to 0.42 mg/L and for the January 2012 sampling event ranged from 0.16 to 0.40 mg/L. DO concentration s for the intermediate aquifer zone monitoring wells sampled during the August 2011 sampli ng event ranged from 0.12 to 0.47 mg/L and for the January 2012 sampling event ranged from 0.18 to 1.04 mg/L. The DO values are generally with in a range that suggests that reductive pathways for natur al attenuation are tolerated. 2.6.2.3 Review of Surface Water COC Data In addition to groundwater and natural attenuati on monitoring, surface water monitoring of iron concentrations has also been conducted in Wetland 3 since March 2000. During the monitoring period, surface water samples collected from Wetland 3 continued to present iron concentrations exceeding Florida surface water standards and NAS Pensacola site specific background criteria. The iron concentrations remain less than the 700,000 to 1,800, 000 g/L concentrations reported in August 2000. Total iron concentrations reported for surface wate r location 01W01 during these sampling events were lower than results reported for the previous two year s of monitoring. Iron concentrations reported for down-gradient surface water location 01W02 have been variable, fluctuating by an order of magnitude between sampling events with no apparent trend.

Surface water samples were collected at three loca tions as part of two semiannual sampling events conducted in August 2011 and January 2012. Two of the surface water sample locations are in Wetland 3, which is located adjacent to and downstream of OU1. Surface water sample 01SW01 is located at a groundwater to surface water seep area in the southwestern portion of Wetland 3 (which is approximately 250 feet south of the pr evious location) and 01SW02 is located prior to the culvert that connects Wetland 3 to Wetland 4. The third surface water sample location, 01SW03, is the Point of Compliance (POC) sample location in Wetland 4D for the discharge of surface water from Wetland 4 into Bayou Grande. Surface water sample location 01SW01 contained total iron at concentration of 5,220 g/L and surface water sample location 01SW02 contained total iron at 7,050 g/L during the November 2010 sampling event. Both locations contained total iron at concentrations that exceed t he freshwater background concentration of 4,720 g/L. Surface water sample location 01SW03 contained total iron at a concentration of 427 g/L. During the August 2011 and January 2012 sampling events, surface water sample location 01SW01 could not be sampled because the seep location was dry. In August 2011, surface water sampling location 01SW02 contained total iron at a concentra tion of 12,900 g/L, which exceeds the freshwater background concentration 4,720 g/L. The concentrations of total iron for the August 2011 sampling event at surface water sample location 01SW02 at Wetland 3 exceeded the Class III Predominantly Marine surface water quality criteria of 1,000 g/L per Chapter 62-302, F.A.C. The concentration of total iron at surface water sample location 01SW03 duri ng the August 2011 sampling event was 265 g/L, and 291 g/L for the duplicate sample. Neither surface water sample contained total iron at a concentration that exceeded the estuarin e wetland background threshold of 5,8 62 g/L and the Class III Predominantly Marine surface water quality criteria per Chapter 62-302, F.A.C. Surface water sampling location 01SW02 contained total iron at 6,500 g/L, and 5,840 g/L for the duplicate sample, which exceeds the fres hwater background concentration 4,720 g/L. The concentrations of total iron for the January 2012 sampling event at surface water sample location 01SW02 at Wetland 3 also exceeded the Class III Predominantly Mari ne surface water quality criteria of 1,000 g/L per Chapter 62-302, F.A.C. The concentration of total iron at surface water sample location 01SW03 (point of compliance location) during the January 2012 sampling event was 347 g/L, which is below the estuarine wetland background threshold of 5,862 g/L and the Class III Predominantly Marine surface water quality criteria per Chapter 62-302, F.A.C.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 2-21 CTO 0030 Surface water samples collected from Wetland 3 du ring the 2011 and 2012 sampling events continued to have iron at concentrations exceeding FDEP surface water standards. However, the iron concentrations detected in 2011 and 2012 are considerably lower t han the concentrations (700,000 to 1,800,000 g/L) detected in 2000. Because the sources for total iron in the surface water at Wetland 3 is a seep discharging from the former OU1 landfill and from groundwater discharge, it is recommended that the surfac e water sample locations 01SW01, 01SW02, and 01SW03 should continue to be monitored. The semiannual sampling schedule should be preserved. Continuation of the semian nual monitoring would help ensure that potential sources of known and unknown cont aminants are protective of human health and the environment and are attaining groundwater cleanup goals through natural attenuation. 2.6.2.4 LUC Inspections LUC inspections were conducted annually at OU1 during the period under review. The inspections noted no problematic observations. In addition, because of the May 2002 land transfer of a tract of land associated with OU1 to the VA, the LUC complian ce is coordinated between the Navy and the VA. 2.6.3 Site Inspection and Interviews An inspection was conducted at the site on May 3, 2012 by Tetra Tech and NAS Pensacola personnel. The purpose of the inspection was to assess the protec tiveness of the remedy, including the condition of the monitoring wells, and the condition of the wetlands. The institutional controls that are in place include the restriction of groundwater use within 300 feet of the site and limiting intrusive activities within the landfill boundary without prior approval from the NAS Pensacola Environmental Office. At the time of the inspection, institutional controls were found to be adequate, and use of groundwater was not observ ed. Roadways within OU1 appeared adequate and there were no apparent signs of vandalism or trespassing. During a separate regulatory site visit in 2011, an OU1 monitoring well was observed to be open and several additional monitoring wells were unlocked or in disrepair. Following the site visit, the Navy completed immediate monitoring well repair and initiated a facility wide monitoring well inventory to assess the condition of all existing monitoring wells. It was noted during the Five-Year Review inspection that fenc ing and signs are in place to notice the restricted access to Barrancas National Cemetery, but not specifically for restricting access to OU1. According to the NAS Pensacola Environmental Office, 49.83 acres was transferred to the VA on May 23, 2002 to provide additional burial plots and space for construction of administrative and maintenance building structures. A portion of th e land transferred from the Navy to the VA was

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 2-22 CTO 0030 inadvertently located in OU1. The location of th e VA transferred land located inside the OU1 boundary is depicted on Figure 2-1. As evidenced by this figure, the VA out parcel encompasses a portion of the southern soil LUC boundary for OU1. An interview was conducted with Greg Campbell, Environmental Engineer for NAS Pensacola, on May 2, 2012. According to the interview, Mr. Campbell indicated he is well informed about the sites activities and progress, and was not aware of any comm unity concerns regarding the site or its operation, or of any incidents such as vandalism, trespassing, or emergency responses at the site. The interview forms are presented in Appendix B. Mr. Campbell indicated annual LUC inspections are performed. In addition, complaints, violations, or other incidents related to the site requiring a respon se by his office have not occurred. Mr. Campbell indicated his opinion that the closure of the iron recovery system was appropriate. 2.6.4 ARAR Level Changes The following standards were identified as chemical-spec ific ARARs in the ROD. They were reviewed for changes that could affect protectiveness: RCRA MCLs (40 CFR 264 Subpart F) Federal Safe Drinking Water Act MCLs (40 CFR 141.11 141.16) Safe Drinking Water Act Maximum Contaminant Level Goals (MCLGs) (40 CFR 141.50 141.51) Florida Water Quality Standards, Chapter 62-3, F.A.C. Florida Surface Water Standards, Chapter 62-301 and 302, F.A.C. Florida Drinking Water Standar ds, Chapter 62-550, F.A.C. Florida Water Quality Standards, Chapter 62-3, F.A.C., was repealed in 2000 and minimum groundwater quality criteria is currently provided in Ground Water Classes, Standards, and Exemptions, in Chapter 62550, F.A.C. The action levels for triggering cont ingent action at OU1 are the Florida surface water standards for Class III Pred ominantly Marine freshwater and the Fl orida drinking wa ter standards. New surface water monitoring criteria was presente d in the Reconnaissance Phase Flow Control Pilot Study completed in March 2009. The freshwater wetland background threshold for iron was determined to be 4,720 g/L and the estuarine wetland backgrou nd threshold was determined to be 5,862 g/L. Contaminant CTLs, Chapter 62-777, F.A.C. (Ame nded 4/17/05) and Contaminated Site and Cleanup Criteria, Chapter 62-780, F.A.C. were promulgated by Florida after the ROD and establish cleanup levels

PAGE 51

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 2-23 CTO 0030 for soil, groundwater, and surface water. These new criteria need to be considered to determine if the remedy is still protective. Chapter 62-777, F.A.C. provided GCTLs for cont aminants without MCLs per Chapter 62-550, F.A.C. Additionally, Chapter 62-777, F.A.C. provided surface water cleanup target levels (SWCTLs) for contaminants that di d not have surface water quality criteria listed in Chapter 62-302, F.A.C. The Chapter 62-777, F.A.C. SWCTLs ar e applicable for surface water and for groundwater discharging to surface water (both fresh and saline environments). As described in the previous Five-Year Review, the concentrations of four contam inants (trans-1,2-dichloroethene, 1,2-dichloroethane, 1,4-dichlorobenzene, and chlorobenzene) that are not listed in Chapter 62-302, F.A.C but are listed in Chapter 62-777, F.A.C. were not detected in Wetlan d 3 surface water samples. Thus, the use of the CTLs provided in Chapter 62-777, F.A.C. does not affect the protectiveness of the groundwater remedy. Chapter 62-780, F.A.C. provides rule s for the cleanup of non-petroleum sites with contaminants that have been released or discharged into the environment. To the extent rules promulgated per Chapter 62-780, F.A.C. may apply as chemical specific ARARs, they do not affect the protectiveness of the remedy. Since the ROD for OU1 was finalized in 1998, changes to federal regulations in 2002 and 2006 and to Florida regulations in 2005 lowered the MCL for arsenic in groundwater from 50 to 10 g/L. On January 22, 2001, the USEPA adopted a new MCL for arsenic in drinking water at 10 g/L, replacing the old standard of 50 g/L. The USEPA rule became effe ctive on February 22, 2002 and became enforceable to water systems on January 23, 2006. Floridas drin king water standards are contained in Chapter 62550, F.A.C. Floridas primary drinking water standard s, which are health based, are described in Rule 62550.310, F.A.C. Florida changed its MCL for arsenic fr om 50 g/L to 10 g/L on January 1, 2005. This change in the federal and state MCL for arsenic was included in a draft ESD for OU1 (Tetra Tech, 2012). However, based on comments received from the USEPA, The ESD will be suspended and in its place a ROD amendment will be completed. The change in the fede ral and state arsenic MCL will be included in a ROD amendment that is being developed to address the change in the selected remedy. There have been no other changes in Safe Drinking Water Act and Chapter 62-550, F.A.C. MCLs that may affect the protectiveness of the remedy. The Wetlands Protection Policy, authorized under Ex ecutive Order 11990, remains unchanged and is the only location-specific ARAR for OU1. The following standards were identified as action-spe cific ARARs for OU1, governi ng actions such as the construction of landfills: RCRA Groundwater Monitoring Re quirements (40 CFR 264 Subpart F)

PAGE 52

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 2-24 CTO 0030 Clean Water Act Discharge Limitations National Pollutant Discharge Elimination System (NPDES) Permit (40 CFR 122, 125, 129, 136) Pretreatment Standards (40 CFR 403.5) Safe Drinking Water Act Underground In jection Control Program (40 CFR 144) Florida Rules on Permits, Chapter 62-4, F.A.C. (Amended 02/16/12) Florida Underground Injection Control Regulati ons, Chapter 62-528, F. A.C. RCRA Solid Waste Groundwater Monitoring Requirements The Florida rules on permits (F.A.C. Chapter 62-4) were amended on February 16, 2012. The amendments to this rule do not affect the protectiveness of the remedy. The groundwater interception system was decommissioned in May 2010, so NPDES, Pretreatment Standards, and 62-4, F.A.C. are no longer pertinent. There is no underground injection, so the underground injection control regulations are no longer pertinent. The remaining standards remain unchanged and are RCRA requirements. 2.7 TECHNICAL ASSESSMENT The following conclusions support the determination that the remedy at OU1 is expected to be protective of human health and the environment. 2.7.1 Question A: Is the remedy functioning as intended by the ROD? Remedial Action Performance: Prior to decommissioning in May 2010, the groundwater interception system remedy was functioning, on a mechanical basis, as designed; however, the groundwater interception system was not effectively treating iron contaminated groundwater migrating from the OU1 landfill and discharging into Wetland 3, as is evidenc ed by the elevated iron concentrations present in Wetland 3 surface water. The design and subsequent performance of the trench was not sufficient to capture and extract all of the iron contamination migrating to Wetland 3 from OU1 because of the prevalence of iron within the shallow groundwate r upgradient, side-gradient, and downgradient to the groundwater interception system. In summary, the groundwater interception system was not meeting, or expected to meet, the reductions necessary for cleanup. The concentrations of iron at surface water sample locations 01SW01 and 01SW03 during the January 2012 sampling event were below the fres hwater background concentration, and the iron concentration at surface water sample location 01SW02 exceeded the freshwater background concentration. Considering that Wetland 3 is already an integral part of the treatment process for iron, it is expected that iron concentrations in Wetland 3 will remain stable and may decrease over time. The results from the

PAGE 53

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 2-25 CTO 0030 surface water samples should be monitored to confir m that the iron concentrations do not exceed the 4,720 g/L freshwater wetland background value and the estuarine wetland background of 5,862 g/L at the point of compliance location (01SW03). System Operations/O&M: The groundwater interception system groundwater treatment system was decommissioned in May 2010. Cost of System Operations/O&M: System operations and O&M cost-t o-date from 1999 to 2012 for the groundwater recovery and treatment sy stem were approximately $1,754,466. Opportunities for Optimization: The Optimization Study wa s approved by the USEPA on March 29, 2007. All FDEP comments were addressed in correspondence dated November 27, 2007. Because the groundwater interception system was not meeting the RAOs, modification of the existing remedy was necessary. The necessary modifications included discontinuing active pumping of the ITS, modification of the remedial goals for the existing remedy, and continuation of long-term groundwater and surface water monitoring programs to ensure the modifications are protective of human health and the environment. The RAO for protection of Wetland 3 was modified because iron concentrations in groundwater were below human health and ecological risk-based levels. Long-term groundwater monitoring is being conducted to verify that natural attenuation processes are decreasing concentrations of organic compounds and will eventually attain per formance standards. Surface water monitoring is being conducted to verify that discharges from OU1 to Wetland 3 and Wetland 4 do not cause unacceptable to impacts to Bayou Gr ande (a state-classified Class III Predominantly Marine water body). The Optimization Study found that Wetland 3 is naturally treating the iron and field observations indicate healthy vegetative growth in Wetland 3. The vegetation also provides an unspecified amount of evapotranspiration in the wetland which aids in treatment. Implementation of Institutional Controls and Other Measures: The MOA was completed on August 31, 1999, and was approved and authori zed by the responsible part ies including USEPA, FDEP, and the Navy. The LUCIP was included as an appendix to the MOA. OU1 is reported to have been inspected quarterly to insure the institutional controls remain in place and an Annual Review Report has been completed. No water supply wells are within the area restricted by the LUCIP.

Exposure Assumptions: There have been no changes in the physical conditions of the site that would affect the protectiveness of the remedy. Changes in Standards and To Be Considered (TBC) Criteria: ARARs and TBCs considered during preparation of the ROD were reviewed to determi ne changes to standards since the remedy was implemented. The arsenic MCL per the Safe Drin king Water Act, and Chapter 62-550, F.A.C has been changed from 50 g/L, which was the MCL at the time of the ROD, to 10 g/L. Changes in Exposure Pathways: No changes in the site conditions or land use that affect exposure pathways were identified as part of the Five-Year Review. Changes in Toxicity and other Contaminant Characteristics: Toxicity and other factors for COCs have not changed. Changes in Risk Assessment Methodologies: Changes in risk assessment methodologies since the time of the ROD do not call into questi on the protectiveness of the remedy. 2.7.3 Question C: Has any other information come to light that could call into question the protectiveness of the remedy? No other information that could call into question t he protectiveness of the remedy has been discovered. 2.8 ISSUES Issues were discovered during the Five-Year Review and are noted in Table 2-6.

The OU is primarily paved or covered by buildings and is approximately 68 acres. The sites comprising OU2, described below, are north of Chevalier Field, near Murray Road, and west of Pensacola Bay. Site 11 Site 11, shown in Figure 3-1, is a former landfill wh ere industrial and municipa l wastes were disposed of and burned from the late 1930s to the mid-1940s. The area occupies approximately 20 acres southwest of an extension of Bayou Grande called the Yacht Basin. Surface elevati ons at the site are approximately 5 feet above mean sea level, and the site surface slopes gently eastward toward Bayou Grande. Two prefabricated buildings, Buildings 3627 and 3628, were formerly located near the center of the site. Building 3445, south of the sites southeastern corner is used to store outdated office equipment. Much of the site is covered with vegetat ion. Fenced areas to the north a nd south of Building 3445 are used for

PAGE 59

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 3-4 CTO 0030 outside storage of boats, trucks, and heavy equipment. Pat Bellinger Road runs north-south through the center of Site 11. According to the IAS conduc ted by the Naval Facilitie s Engineering Service Center (NFESC), the Site 11 landfill was used to burn refuse through the mid-1940s. During this time, it received combustibles such as fuels, solvents, and waste oil from aircraft engine overhauls. During landfill operations from the early 1930s to the 1940s, approximately 24 cubic yards of material were disposed of daily from several NAS Pensacola locations. During this time, an unknown number of 55-gallon drums of unknown contents were observed. Until the 1950s, oil slicks were obser ved during heavy rains in the Yacht Basin. Site 12 Site 12, shown in Figure 3-1, is currently referred to as the Defense Reutilization and Marketing Office (DRMO) Recyclable Materials Center and is used to store scrap metal. The site is approximately 800 feet northwest of former Chevalier Field and immedi ately west and upgradient of Site 26. Most of the site area is enclosed by a chain-link fence and co vered with a large concrete pad which is used as a heavy equipment storage area. Buildings 455 and 3821 are in the southern portion of the site. Building 455 includes an office, break area, and storage warehouse, and Building 3821 is a storage warehouse. A third building, 3444, has been demolished. From the early 1930s to the 1940s, garbage was stored at Site 12 in an area known as Pig Sty Hill near Building 455. Approximately 16 cubic yards (described as two truckloads) per day of wet garbage were stored here before being hauled off for livestock feed. The site has since been used for scrap metals storage. Site 25 Site 25, shown in Figure 3-2, is an approximatel y 50-foot by 50-foot concrete-paved area located immediately east of Murray Road and north of Farrar Road. The site is flat with land surface elevations averaging approximately 22 to 25 feet above mean sea level. Where expo sed, site surface soil is sandy and well drained. The site includes an area east of the radium decontamination building (Building 780) where a radium spill is reported to have occurred in 1978. A former helicopter scrap yard approximately 25 feet east of Building 780 is currently used as a parking area for Navy Exchange semi-trailers.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 3-7 CTO 0030 Building 780 currently houses the Joint Oil Analysi s Laboratory, which is used for quality assurance analysis of oil from aircraft and vehicles. Building 780 was constructed in 1951 to house oxygen and carbon dioxide shops. In approximately 1975, a radium decontamination operation was added to Building 780. Radium wastes from this operation were stored in a drum on site before being disposed of. In 1978, a spill occurred in the storage area between Bu ilding 780 and the scrap yard. Approximately 25 gallons of low-level radium paint waste spilled from a ruptured, eroded drum onto the underlying concrete floor. The waste was reportedly cleaned, placed in a secure container, and sent to a proper disposal site. The exact location of the spill, details of the cle anup operation, and whether the waste reached unpaved soil were not determined from the existing records. Site 26 Site 26, shown in Figure 3-1, is northwest of former Chevalier Field and immediately south of Building 684. The approximately 150-foot by 200-fo ot area houses an open metal shed near a former chemical storage building. DRMO uses this area to st ore paints, fuels, and solvents. Site access is limited by an 8-foot chain-link fence surrounding the st orage area. The concrete pavement inside the fence is bordered by sandy soil and mowed grass. Site 26 is bounded on the west by a paved road and Site 12 and on the east by a wooded area (Site 11). The site gently slopes eastward to a topographic break where elevations abruptly drop to approximately 5 feet above mean sea level. From 1956 until 1964, the supply department used Site 26 to store incoming paint strippers and acids. Containers of these materials placed outside on steel matting sometimes leaked, discharging the materials onto the ground. Site 27 Site 27, shown in Figure 3-2, extends through th e concrete foundation of former Building 709. The building was demolished and the foundation is currently a parking lot. The building foundation is 2 to 4 feet above the surrounding area. Outside the foundat ion the ground surface is unpaved. The site is approximately 150 feet west of Building 780 and bou nded by Farrar and Murray Roads on the south and west, respectively. An adjacent parking lot north of the building foundation is asphalt-paved, and a gravel and shell parking lot is northeast of the foundation. All roads within the site are paved with either concrete or asphalt. Originally, the site consisted of a small radium dial shop in former Building 709 with a connection to the sanitary sewer. However, the results of analysis of RI soil samples collected in the vicinity of the Building 709 foundation expanded the site area to approximately 6 acres.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 3-8 CTO 0030 Building 709, constructed in 1941, was used for seve ral operations including carburetor repair, propeller repair, painting and maintenance, various instrument sh ops (including a radium paint room), and a plating shop. In 1949, a small shop in Building 709 was used to rework luminous instrument dials. Worn and damaged instruments were returned to this shop to be stripped and repainted. From 1941 to 1965, the stripping procedure required soaking the instruments in benzene, scraping them in a benzene or water bath, or dry scraping and painting them under a vent ilation hood. After 1965, the procedure switched to scanning the instruments for radium and then stripping them with paint stripper and a lye-nitric acid solution. Contaminated instrument cases were soaked in another acid solution called Turco and then scrubbed with a wire brush. Building 709 also housed a large plating operation from 1941 to approximately 1970. The operation involved the use of 50 solution tanks ranging from 50 to 3,865 gallons in capacity. A routine disposal operation in former Building 709 involved washing spent cleaning solutions and luminous paint down the drains into the sanitary sewer. The disposed wastes from this location included cleaning solutions containing benzene, white pigment s, phosphorus, radium, and small amounts of acidic or caustic solutions. Plating wastes from former Building 709 and shops in Buildings 604 and 649/755 were periodically dumped through drains into the sanita ry sewer. Most of the building drains connected to a single line draining into the sanitary sewer line. From 1941 to 1948, all wastes from former Building 709 were discharged directly into Pensacola Bay. From 1941 to 1962, concentrated cyanide wastes from Building 709 were periodically dumped into the sanitary sewer. After 1962, the cyanide was drummed and disposed of 15 miles offshore in the Gulf of Mexico, although small quantities of cyanide continued to be discharged into the sewer. Plating operations ceased in Building 709 by 1973. Site 30 Site 30, shown in Figure 3-2, covers approximatel y 35 acres and is also known as the Building 649 complex. The complex includes interconnected Buildings 647, 648, 649, 649B, 692, 755, and 3815 and several smaller, separate, associated buildings. The buildings were used by the Dynamic Component Division of the former NADEP and several aircraft component repair functions. In addition to the buildings, the Site 30 investigation included a portion of the sewer line from the Building 649 complex to the IWTP. The sewer line investigation included lines at Sites 25, 27, and 30 and their downstream segments along with the sewer extending from the Building 649 complex, the feeder line from Building 3220, and the main line running to the IWTP. Wetland 5A is located to t he south of Site 30. Surface water from the wetland drains to the southeast to a ditch that flows northeastward to the Yacht Basin. Operations in the Site 30 complex began in the 1940s and continued until NADEP closed. Aircraft and parts were painted in booths in the Building 649 complex beginning in 1940. The paints used at NAS

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 3-9 CTO 0030 Pensacola were cellulose nitrate lacquer, zinc chro mate, nitrate dope, acetate dope, day glow, epoxy, and enamel. Thinners used were lacquer thinner, toluene, and MT 6096. A tin-cadmium plating shop operated in the Building 649 complex from the mid-1940s to the early 1960s. At this time, it was replaced by a magnesium treatm ent line, which operated until the early 1970s. Near Building 649, 15 tanks ranging in capacity from 200 to 500 gallons contained solutions of tin, cadmium, and cyanide. Additionally, a 250-gall on tank stored trichloroethene, and a 500-gallon UST, located on the northern end of Building 649, stored waste oil. The cont ents were drained periodically into a ditch east of the building. Based on current topography and hist orical data, this ditch was either Wetland 5A or a topographical low draining to Wetland 5A. When the tin-cadmium operation was replaced by a magnesium treatment line in the early 1970s, the 15 tanks near Building 649 were then used to store acids, caustics, degreasers, chromate solutions, and potassium permanganate. In the summer of 1994 as part of an interim remo val action (IRA), the NAS Pensacola Public Works Center (PWC) removed an aircraft engine shipping cont ainer from Wetland 5A immediately southeast of Building 649. The shipping container, referred to as the waste receiving structure, had been used as an oil-water separator. Wetland 5A was sampled under the Site 41 (NAS Pensacola Combined Wetlands) investigation. A second plating shop in Building 7 55 was used from the early 1960s until the early 1970s and included 50 tanks ranging in capacity from 50 to 200 gallons and containing metal plating solution including nickel, chromium, silver, lead, and tin. Concentrated cyanide wastes generated in Buildings 649 and 755 were disposed of in the same manner as Building 709s cyanide waste. Disposal involv ed discharging the wastes down the sewer from 1941 to 1962 and discarding drummed waste in the Gulf of Mexico after 1962. Cyanide waste generation stopped in the early 1960s when the tin-cadmium line was re placed by the magnesium treatment line. Overflow discharged into the sewer. An empty fiberglass UST mounted in concrete is still located near the southeastern corner of Building 692. Installed in 1986, this tank stored JP-1/J P-5 (jet fuel) calibration fluid for use in Building 692. The fiberglass tank replaced an older steel tank also used to store calibration fluid. The older tank had at least one undocumented spill. A UST along the western side of Building 692 supplied Building 755 with methyl ethyl ketone via underground pipes. Several other USTs were located along the northern side of Building 692; their exact contents are unknown. Some of the storage tanks may have contained chromium wastes. The original WWTP, built in 1948, was replaced in 1971 with a modern plant that could accept industrial wastes. Most facilities di scharging to the sewer did so without an y pretreatment or waste segregation.

PAGE 65

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 3-10 CTO 0030 The waste stream has included paint strippers, heavy metals, pesticides, radioactive wastes, fuels, cyanide waste, and waste oil. The IWTP sewer line consisted of vitrified clay and cast-iron piping installed both before and after 1971. 3.2.2 Land and Resource Use at OU2 OU2 is an industrial area, and because NAS Pensacola is not proposed for Base Realignment and Closure, it is reasonable to assume that the facility and OU2 will continue to be used for industrial or nonresidential purposes in the foreseeable future. The groundwater at OU2 is not used at this time, and NAS Pensacola does not anticipate its future use. However, groundwater beneath OU2 is considered a potential source of drinking water (G-2) under Florida regulations. 3.3 HISTORY OF CONTAMINATION AT OU2 One soil sampling event during the RI was performed at all sites in OU2 and is summarized in the RI Report (EnSafe, 1997). Soil data identified constituents in surface and subsurface soil at concentrations greater than residential and industrial direct ex posure Soil Cleanup Target Levels (SCTLs), and leachability to groundwater SCTLs per Chapter 62-777, F.A.C., and NAS Pensacola background concentrations. The estimated volume of soil that exceeds industrial SCTLs is 18,252 cubic yards. RI groundwater sampling data were compared to Feder al Safe Drinking Water Act, Florida Chapter 62550, F.A.C. and Chapter 62-777, F.A.C. CTLs; Fl orida SWCTLs per Chapter 62-777, F.A.C.; and NAS Pensacola background concentrations to evaluate the nature and extent of contamination. NAS Pensacola background concentrations for aluminum, antimony, and iron exceeded their associated CTLs, indicating that these metals naturally occur at c oncentrations that exceed federal and state regulatory criteria at NAS Pensacola. Based on data collected during the RI, the estimat ed volume of groundwater with aluminum, iron, and manganese at concentrations exceeding their CTLs is approximately 14,400,000 gallons. The estimated volume of groundwater with barium, cadmium, chro mium, and lead at concentrations exceeding their CTLs is approximately 2,260,000 gallons. The estimated volume of groundwater with VOC concentrations exceeding their CTLs is approximately 13,500,000 gallons. The estimated volume of groundwater with SVOC at concentrations exceedi ng their CTLs is approximately 820,000 gallons. Although contaminants were detected in soil and grou ndwater samples, a strong correlation between soil and groundwater contamination was not identified in the RI Report.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 3-11 CTO 0030 3.3.1 Initial Investigation at Site 11 The source of contamination at Site 11 was identified as a former landfill, where trenching revealed evidence of a seam of blackened debris at the water table. This oily material contained corroded bits of metal and other debris. COCs for Site 11 are presented in Table 3-2. 3.3.2 Initial Investigation at Site 12 The storage of scrap metals may continue to contribute to the metals contamination at this site. Although it was not noted during the RI field investigation, pa st storage of old transformers pending their disposal may have contributed to the PCB contamination at Site 12. Residual fuels and oils from scrapped aircraft and vehicles stored at the site are possible sources of SVOCs. A Radiological Scoping Survey completed at Site 12 in 2009 indicated Radium 226 impacted soils were present. COCs for Site 12 are presented in Table 3-2. 3.3.3 Initial Investigation at Site 25 Improper storage and disposal of materials at Buildin g 780 are possible sources of soil contamination at the site. Another location of concern at Site 25 is the storage yard north of Building 225, which was used as a metal prefabricating shop by the NAS Pensacola PW C. This yard contains racks of materials such as metal sheeting and piping. COCs for Site 25 are presented in Table 3-2. 3.3.4 Initial Investigation at Site 26 Possible sources of contamination in clude the storage of paint s, fuels, and solvents. COCs for Site 26 are presented in Table 3-2. 3.3.5 Initial Investigation at Site 27 This site was originally investigated because of the sewer from the Radium Di al Shop. The sources of organic and inorganic contaminants are uncertain. T he radiological survey revealed a small area of contamination south of former Building 709. From th e size of the area, the c ontamination appeared to be from a spill adjacent to an old stairway from Buildi ng 709. Outside this limited area, significant soil radiological contamination was not found on this site A Radiological Scoping Survey completed at Site 27 in 2009 confirmed Radium 226 impacted soils were present. COCs for Site 27 are presented in Table 3-2.

COCs for Site 30 are presented in Table 3-2. 3.3.7 Basis For Taking Action at OU2 Concentrations of COCs in surface soil, subsurface soil, and groundwater were identified in the Human Health and Screening Level Ecological Risk Assessments that was presented in the RI Report and ROD (Tetra Tech, 2008b). The RI and ROD indicated the COCs present an unacceptable risk to human health for future site residents, future and current site wo rkers, and adolescent trespassers, but did not result in unacceptable risks to ecological receptors (Tetra Tech, 2008b).

RAOs were established in the FS to aid in the development and screening of remedial alternatives to be considered for the ROD. The OU2 FS, Proposed Plan, and ROD did not include Radium 226 as a COC. The presence of Radium 226 will be addressed in a ROD Amendment. The purpose of the remedial action at OU2 is to reduce the unacceptable risks to human health and the environment associated with exposure to COCs in groundwater and soil. To meet these goals, three RAOs were identified. Table 3-3 lists the RAOs for OU2.

Of the alternatives evaluated, the remedial actions selected for OU2 were Alternative S-5 for soil (Excavation and Off-site Disposal with LUCs) and GW-3 for groundwater (MNA and LUCs) as listed in the ROD fo r OU2. The major components of Alternative S-5 and GW-3 are listed below: Natural attenuation of contaminated groundwater primarily due to hydraulic dispersion, adsorption onto soil particles, and biodegradation. Excavation of soil contaminated by COC from Site s 11, 12, 25, 27, and 30, such that the average contaminant concentrations based on the 95 perc ent upper confidence limit meet the state of Florida industrial direct exposure SCTLs.

PAGE 70

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 3-15 CTO 0030 Implementation of LUCs. Groundwater monitoring to evaluate whether migr ation of COCs is occurring and to assess whether natural attenuation is occurring. The remedy was selected for the following reasons: After removal of soil identified for excavation, concentrations of COCs remaining in soil will no longer present an unacceptable threat to human health or the environment assuming that only non-residential uses of the sites are permitted. Surface soil areas identified as containing COCs at concentrations exceeding state of Florida industrial direct exposure SCTLs will be removed and replaced with clean fill to prevent unacceptable risks. Although contamination is present in groundwa ter at concentrations greater than federal and state CTLs, detected concentrations are relatively low and do not present an unacceptable risk to human health or the environment under the groundwater use restrictions to be implemented as part of the selected remedy. The contaminant plume is small and confined to the shallow aquifer. Soil excavation for CERCLA contaminants originally planned for Site 11 will not be conducted due to a proposed change in remedy after discovery of asbes tos containing material (ACM). However a pregamma walkover and a RESRAD/Micro-shield run will be completed to verify radiation levels following completion of the soil cover. The thickness of t he existing soil cover will be evaluated and additional soil cover will be added, if necessary, in place of the hotspot soil excavation described in the ROD. Finding of ACM as a CERCLA contaminant and the change in the remedy selected in the ROD will be addressed in a ROD Amendment. 3.4.2 Remedy Implementation at OU2 3.4.2.1 MNA and Long-Term Monitoring The OU2 ROD specified MNA of contaminated gr oundwater. Natural attenua tion will rely on naturally occurring processes within the surficial aquifer to reduce contaminant concentrations in groundwater. Hydraulic dispersion thr ough aquifer movement, adsorption on so il particles, and biodegradation will be the main attenuation processes. Surficial aquifer conditions will be periodically monitored to ensure contaminant concentrations are being adequately reduce d through natural processes. This component of the remedy has not yet been implemented.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 3-16 CTO 0030 3.4.2.2 Excavation and Off-Site Disposal of Contamination The OU2 ROD specified removal and off-site disposal of soil impacted by the COCs to reduce the direct exposure potential at the site such that the average soil contaminant concentrations based on the 95 percent upper confidence limit meet their state of Florida industrial direct exposure SCTLs. The combined areas of contaminated soil that will be ev aluated by supplemental sampling and analysis to determine the 95 percent upper confidence limit c oncentrations for excavation covers approximately 246,400 square feet. Excavations will be advanced to a depth of approximately 2 feet bls. In the ROD it was estimated that the maximum volume of soil to be excavated and disposed is 18,250 cubic yards. The ROD also indicated that the excavation limits and estimated maximum volume of soil to be excavated and disposed of may change based on criteria for additional samples needed to determine excavation limits as part of the Remedial Design. The remedi al action completed for Sites 12 and 27 Radium 226 impacted soil was excavation and off-site disposal of approximately 1,149 cubic yards of soil. 3.4.2.3 Land Use Controls The OU2 ROD specified that following soil exca vation, LUCs will be implemented for soil and groundwater. Following soil excava tion, soil and groundwater contam ination will remain at OU2 at concentrations that preclude UU and UE; therefore, the remedy includes LUCs to prevent unacceptable risk due to exposure to the COCs remaining in so il above residential direct exposure criteria and groundwater. The OU2 LUC Boundaries are shown on Figures 3-1 and 3-2. Consistent with the RAOs developed for the OU, the specific performance obje ctives for the LUCs implemented at OU2 are as follows: Prohibit reuse of the site for residential uses incl uding, but not limited to, any form of housing, childcare facilities, any kind of school including presch ools, elementary schools, and secondary schools, playgrounds, and adult convalesc ent or nursing care facilities. Prohibit the excavation, disturbance, and removal of soil unless prior written approval is obtained from the facilitys Environmental Coordinator. Prohibit potable uses of groundwat er from the surficial aquifer underlying the site, including, but not limited to, drinking, washing, cooking, cleaning, and turf irrigation, without prior written approval from the Navy, USEPA, and FDEP.

Maintain the integrity of any existing or future monitoring or remediation system(s). Any time that part of OU2 is considered for an alter native use, a site approval process will be initiated through the NAS Pensacola Environmental Office. Simila rly, for any intrusive activities that are planned within OU2, the Dig Permit process will be init iated through the NAS Pensacola Environmental Coordinator. The restricted area will be delineated and the restriction will be described in the NAS Pensacola Site Management Plan.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 3-18 CTO 0030 The review included the following components: Document Review Data Review Site Inspection Five-Year Review Report development and review 3.6.1 Document Review This Five-Year Review consisted of a review of relevant documents for OU2 including the ROD and Remedial Design, and applicable federal and stat e statutes. The source of ARARs for soil and groundwater cleanup at OU2 was also reviewed for changes to the applicable groundwater cleanup standards. 3.6.2 Data Review Source removal has been implemented but not been completed at Sites 12, 27, or 30. Soil excavation for CERCLA contaminants originally planned for Site 11 w ill not be conducted due to the discovery of ACM. Finding of ACM as a CERCLA contaminant and the change in the remedy selected in the ROD will be addressed in a ROD Amendment. Ground water monitoring is pending approval of the UFP-SAP and Remedial Action Work Plan. 3.6.3 Site Inspection and Interviews LUC inspections were conducted annually at OU2 during the period under review. The inspections noted no problematic observations. 3.6.4 Site Inspection and Interviews Inspections at the site were conducted on May 3, 2012 by Tetra Tech and NAS Pensacola personnel. The purpose of the inspection was to assess the pr otectiveness of the remedy and condition of the monitoring wells. Institutional controls that are in place include the restriction of land use, restriction of all groundwater use, prohibition of the excavation of areas with soils co ntaining COCs without prior approval from the NAS Pensacola Environmental Office, prevent occupati onal exposure to COCs in groundwater in the underlying aquifer by requiring use of PPE and monito ring equipment for excavations that may encounter groundwater, and maintenance of all existing or futu re monitoring and on-site remedy components. At

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 3-19 CTO 0030 the time of the inspection, institutional controls were found to be adequate, and use of groundwater was not observed. Roadways within OU2 appeared adequat e, and there were no apparent signs of vandalism or trespassing. Existing monitoring wells were acce ssible and in good condition. During a separate regulatory site visit in 2011, several OU2 monitoring wells were observed to be unlocked or in disrepair. Following the site visit, the Navy completed an immediate inspection of all OU2 monitoring wells and document the security of each of the monitoring wells Deficiencies were not observed during the site inspection. An interview was conducted with Greg Campbell, Environmental Engineer for NAS Pensacola, on May 2, 2012. According to the interview, Mr. Campbell indicated he is well informed about the Sites that comprise OU2, the individual activities, and progre ss, and he was not aware of any community concerns regarding the site or its operation or of any incidents such as vandalism, trespassing or emergency responses at the site. The interview and inspection forms are presented in Appendix C. Mr. Campbell indicated annual LUC inspections are performed. In addition, complaints, violations, or other incidents related to the site requiring a response by his office have not occurred. 3.6.5 ARAR Level Changes The following standards were identified as chemical-spec ific ARARs in the ROD. They were reviewed for changes that could affect protectiveness: Florida Groundwater Classes, Standard and Exemptions Chapter 62-520, F.A.C. Surface Water Quality Standards Chapter 62302.530, F.A.C. Drinking Water Standards, Monitoring, and Reporting Chapter 62-550.310(4)(b), F.A.C. Contaminant Cleanup Target Levels Chapter 62777.170(1)(a), (1)(b), and (2)(a), F.A.C. in Tables 1 and 2. There were no changes in these requirements that af fect the protectiveness of the remedy. The cleanup goals on Table 2-33 of the ROD were compared to the SCTLs for soils per Chapter 62-777, F.A.C.; CTLs for groundwater per Federal Safe Drinking Water Act, Chapter 62-550, F.A.C.; Chapter 62-777, F.A.C.; and Marine Surface Water Cleanup Target Level (M SWCTLs) for surface water and the discharge of surface water to groundwater per Chapter 62-777, F.A.C. and to the Class III Marine Water values per Chapter 62-302, F.A.C. The following differences were noted: For cadmium, the value for the MSWCTL on Table 2-33 is listed as 9.3 g/L, but the current version of Table 1 in Chapter 62-777, F.A.C. refers to Chapter 62 -302, F.A.C. which gives a value of 8.8 g/L. This slight difference would not affect the protectiveness of the remedy.

PAGE 75

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 3-20 CTO 0030 For dieldrin, the SCTL for leachability to ground water on Table 2-33 is listed as 2 milligrams per kilogram (mg/kg); however, the current version of Table 2 in Chapter 62-777, F.A.C. gives a value of 0.002 mg/kg. The Remedial Design was reviewed, a nd the correct value of 0.002 mg/kg was used in the design. Therefore, this does not a ffect the protectiveness of the remedy. For zinc, the leachability to groundwater SCTL on T able 2-33 is listed as 6,000 mg/kg; however, the current version of Table 2 in Chapter 62-777, F.A.C. notes that the leachability to groundwater value may be derived using the Synthetic Precipitation Leaching Procedure (SPLP) Test to calculate a site-specific SCTL. The FS was based on the 6,000 mg/kg value and no site-specific value was calculated. Because zinc was not identified as a COC in groundwater, it is unlikely that zinc is migrating from the soil at sufficient concentrations to adverse ly affect the groundwater. Therefore, this does not affect the protectiveness of the remedy. There were no location-specific ARARs for this remedy. The following standards were identified as action-specific ARARs for OU2: RCRA Identification of Hazardous Waste (40 CFR 261.11 and 264.13(a)(1)) RCRA Land Disposal Restrictions (LDRs)( 40 CFR 268.49) Florida General Pollutant Emission Limita tion Standards Chapter 62-296.320, F.A.C. Florida Water Well Permitting and Construction Requirements Chapter 62-532.500, F.A.C. Florida Hazardous Waste Requirements for Re medial Action Chapter 62-730.225 (3), F.A.C. Florida Natural Attenuation with Monitoring Regulation Chapter 62-780.690(8)(a) thru (c), F.A.C. The soil removal component of the remedy has been implemented, but not been completed so construction completion reports or similar documents are not available for review. Thus, compliance with RCRA, Florida General Pollution, Florida Well Perm itting, and Florida Hazardous Waste regulations cannot be fully evaluated; however, t here is no available evidence to indicate that action standards have not been complied with during the soil removal. The LTM Plan was included in the Remedial Design and was prepared according to Florida Natural Attenuation with Monitoring Regulation Chapt er 62-780.690(8)(a) thru (c), F.A.C. The sections covering General Provisions for Water Well Permitting and Construction and Abandonment of Water Wells in 62-532, F.A.C. were repealed October 7, 2010. Monitoring well installation and abandonment are now addressed in the FDEP Monitoring Well Design and Construction Guidance Manual, 2008.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 3-21 CTO 0030 3.7 TECHNICAL ASSESSMENT 3.7.1 Question A: Is the remedy functioning as intended by the ROD? The remedy at Site 11 has bee n changed due to the discov ery of ACM. Soil cover will be used in place of contaminated soil excavation. LTM for groundwater has not yet been implemented. LUCs are in place and appear to be adequate based on the site inspection. The remedy at Site 12 has been partially implement ed. Contaminated soil excavation for radiological constituents occurred during 2010 and 2012. Excavation at Site 12F is on hold until confirmatory soil sampling results are evaluated by RASO and cleared for additional non-radiological soil removals. LTM for groundwater has not yet been implemented. LUCs are in place and are adequate based on site inspection. Contaminated soil excavation has been completed in unpaved areas at Site 25. LTM for groundwater has not yet been implemented. LUCs are in place and appear to be adequate based on site inspection. No contaminated soil excavation was required at Si te 26. LTM for groundwater has not yet been implemented. LUCs are in place and appear to be adequate based on site inspection. The remedy at Site 27 has been partially implemented. Contaminated soil excavation has been completed in unpaved areas. Additional soil removal to remediate radiological contamination is dependent on results of future RASO investigations of the former Building 709 drain and sewer lines, which are ongoing as of October 2012. LTM for groundwater has not yet been implemented. LUCs are in place and appear to be adequate based on site inspection. RASO completed a radiation survey of Site 30 excavation areas A through F in 2011. Soil excavation will be completed after RASO investigation results are eval uated for presence of radiological constituents. LTM for groundwater has not yet been implemented. LUCs are in place and appear to be adequate based on site inspection. Remedial Action Performance: Once fully implemented, the remedy is expected to perform as designed. Early Indicators of Potential Remedy Failure: None, the source of the contaminants has been removed and natural attenuation monitoring is to be conducted.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 3-22 CTO 0030 Implementation of Institutional Controls and Other Measures: The Remedial Design was approved by the USEPA in August 2009. Based on the site in spection performed on May 3, 2012, institutional controls have been implemented and are adequate for the site. The reporting and certification requirements for the LU Cs are incorporated into the Land Use Control Assurance Plan (LUCAP) between the Navy, USEPA, and FDEP. OU2 will be available for industrial use, while residential use of the site is prohibited. The Navy performs periodic site inspections to ensure LUCs are properly maintained and administered. Groundwat er use is prohibited within OU2. The Navy conducts annual reviews of the institutional controls to certify whether the LUCs should remain in place or be modified to reflect a change in site conditions. Part of the remedy described in the ROD (2008) includes a Groundwater/Surface Water Interface (GSI) investigation. The purpose of the GSI investigation is to assess whether Sites 11 or 30 are exerting an adverse impact on surface water in the wetlands do wngradient of these two sites. As per the ROD, the GSI will be completed in two phases. Phase I will be an investigation of groundwater contamination at Sites 11 and 30 and installation of nested monitoring wells. Based on Phase I results, the Phase II GSI will be conducted in areas of groundwater discharge into Wetlands 5A, 7, and 64. The information gained from this GSI investigation may be used to opti mize the extent of the areas which would require LUCs and provide additional information on the selected remedial alternative. The UFP-SAP for the GSI is currently under regulatory review. 3.7.2 Question B: Are the exposure assumptions, toxicity data, cleanup levels, and RAOs used at the time of the remedy selection still valid? Exposure Assumptions: There have been minor changes in the physical conditions of the site; however, these will not affect t he protectiveness of the remedy. Changes to Standards and To Be Considered: The ARARs and TBCs considered during preparation of the ROD were reviewed to determine changes to standards since the remedy was implemented. The cleanup goals in the ROD were compared to the current SCTLs for soil, CTLs for groundwater, and MSWCTLs for surface water and groundwater discharging to surface water. No changes in the standards were identified; however, as noted above, several differences were noted. These differences do not affect the protectiveness of the remedy. Because the soil remedial action is not complete, t he action-specific ARARs that relate to the soil remediation component could not be evaluated. The LTM Plan was prepared according to the actionspecific ARAR for LTM Plans.

PAGE 78

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 3-23 CTO 0030 Changes in Exposure Pathways: No changes in the site conditions or land use that affect exposure pathways were identified as part of the five-year review. Exposure to the site groundwater is still restricted by the LUCs. Changes in Toxicity and Other Contaminant Characteristics: There have been no changes in human health toxicity criteria that would im pact protectiveness of the remedy. Changes in Risk Assessment Methodologies: Changes in risk assessment methodologies since the time of the ROD do not call into questi on the protectiveness of the remedy. 3.7.3 Question C: Has any other information come to light that could call into question the protectiveness of the remedy? No other information has come to light that would call into question the protectiveness of the remedy. 3.8 ISSUES Issues were discovered during the Five-Year Review and are noted in Table 3-4. TABLE 3-4 OU2 ISSUES FIVE-YEAR REVIEW NAVAL AIR STATION PENSACOLA PENSACOLA, FLORIDA Issues Affects Protectiveness (Y/N) Current Future The remedy is not fully implemented. Once the remedy is implemented as intended in the ROD and ROD Amendment, the remedy will be protective for the long term. The remedy is protective in the short term as LUCs are being implemented. N Y 3.9 RECOMMENDATIONS AND FOLLOW-UP ACTIONS An ROD amendment is necessary to address the change in remedy at Site 11, due to discovery of ACM, and excavation of radiological contaminated soils at Sites 12 and 27.

FDEP concurred with the ROD on September 15, 2005. This Five-Year Review consists of an approximate fiveyear period of data and provides a status update for OU3, Site 2 Waterfront Sediments. This statutory review is required because hazardous substances, pollutants, or contaminants remain at the site above levels that allow for unlimited use and unrestricted exposure. 4.1 SITE CHRONOLOGY A list of important OU3 historical ev ents and relevant dates in the site chronology is shown in Table 4-1.

This site is an approximate 1,800-foot by 1,400-foot area of nearshore sediments along the sout heast waterfront area, where numerous active storm water and inactive industrial waste sewer outfalls exist. The near shore sediments typically consist of fineto medium-grained sand, silty sand and silty clays. A band of fine-grained sediment (clayey, silty sands to silty clays) extends from the shoreline to approxima tely 200 to 400 feet offshore. Water depths range from 3 to 27 feet. The hydrodynamic regime is charac terized by tides (typically a 2 foot range), tidal currents and waves. All industrial waste outfalls have been inactive since 1973. The southeast waterfront is dominated by a protective concrete seawall with several seaplane ramp s, and is adjacent to a large paved parking apron. The approximate 3to 4-foot high seawall rests on a concrete platform. Fifty-six outfalls, ranging in diameter from 1 inch to 42 inches were previously identified along the seawall (E&E, 1991). The seawall also contains numerous scuppers to drain surfac e water runoff from the adjacent parking areas. In the past, many of the outfalls discharged untreated i ndustrial wastes into Pensacola Bay. This occurred from 1939 to 1973, after which NAS Pensacola's indu strial waste-stream was diverted to the IWTP. Contaminants that sorbed to sediments potentiall y posed excess unacceptable risk to the benthic community and the predatory animals feeding upon them. Surface soil at NAS Pensacola along the shoreline of OU3 are primarily highly permeable sands, which limit stream formation. The depth to groundwater at NAS Pensacola ranges from less than 1 foot to approximately 20 feet bls, depending on land surface elevation and proximity to surface water bodies.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 4-4 CTO 0030 4.2.2 Land and Resource Use at OU3 Boat maintenance, refuelin g services, surface water runoff, routine application of pesticides draining to the Site 2 area, and off-site bay activities (e.g., boat tr affic, non-point source sediment drift) will continue to occur in the Pensacola Bay area near the NAS Pensacola shoreline. Future land use at NAS Pensacola is expected to re main military oriented and under the control of the Navy. Homeland Security Restrictions are in place and prohibit unauthorized boat traffic within 500 feet of the shoreline. Groundwater is not currently used as a potable water source at NAS Pensacola. The main source of potable water for NAS Pensacola is the Navy-owned well field located at Naval Technical Training Center (NTTC) Corry Station, which is located approximately three miles north of NAS Pensacola on the northern (opposite) side of Bayou Grande. 4.3 HISTORY OF CONTAMINATION AT OU3 From 1939 to 1973, untreated industrial wastes fr om NADEP and Naval Air Rework Facilities were discharged into the Pensacola Bay System at Site 2. During that 34-year time span, an estimated 83 million gallons of the following mate rials were disposed of into the bay: waste-containing paint, paint solvents, thinners, ketones, trichloroethylene, Alod ine, mercury, and concentrated plating wastes (primarily chromium, cadmium, lead, nickel, and cyani de [Geraghty and Miller, 1984]). All industrial waste outfalls have been inactive since 1973, and the wastes were diverted to the IWTP. Due to the transport mechanism characteristic of Pensacol a Bay, it is also possible that off-site sources may have affected the site because of the sediment transport mechanisms of an open bay system such as Pensacola Bay. In addition, contaminated groundwater from adjacent OU11, Site 38 has discharged into Pensacola Bay in the Site 2 area. 4.3.1 Initial Investigation for OU3 Investigation at Site 2 occurred from 1993 to 1996. Investigations included a Phase I sampling event to determine total organic carbon (TOC) and grain-size distribution in sediments and a Phase II sampling event to assess contamination. TOC values ranged from less than 0.001 to 0,22 percent, there was no correlation between the TOC and fine grained sediment. Cadmium, copper, lead and zinc appeared to be elevated when compared to natural concentrations. Organic compounds incl uded polynuclear aromatic hydrocarbons (PAHs), pesticides and PCBs that appeared to have a limited lateral distribution.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 4-5 CTO 0030 The human health risk and hazard associated with exposure to Site 2 environmental media were assessed for the hypothetical current and future (combined) child and current and future (combined) adult recreationists crabbing exclusively at Site 2. Ba sed on the Site 2 exposure scenarios, an incremental lifetime cancer risk (ILCR) of 3x10-6, primarily due to heptachlor epoxide, was identified on site. The risk estimate is within the USEPA acceptable risk range of 1x10-4 to 1x10-6, but is slightly above the Florida acceptable risk threshold level of 1x10-6. The calculations are based on the maximum detected concentration in the edible tissue. If the arithmetic average concentration was used, the Florida 1E-6 risk threshold would not be exceeded. Hazard indices (HIs) of 0.7 and 0.2 were calculated for child and adult exposure to Site 2 tissues. No COCs were identified. Subsequent to the completion of the human health risk assessment, Homeland Security Restrictions were established for the surface water bodies surrounding NAS Pensacola. Unauthorized boat traffic is prohibited within 500 feet of the NAS Pensacola shoreline. OU3 is within the restricted area. Effects to marine biota may have occurred as a result of the contaminants present in sediment at some of the sampling locations. At these locations, benthic assemblages appeared to have been altered as a result of high chemical concentrations, but the limited spatial extent of the a ffects may be imperceptible when a bay-wide perspective is considered relati ve to hydraulic movement of sediment. Based on results of the OU3 RI, the presence of a s ource for metals and organics and the physical state of the near shore environment (saline surface water, presence of humic substances, and clay minerals) provides for the accumulation of contaminants; however, only hot spots were id entified and the extent of contamination was delineated. An FS was completed in 1997 to evaluate four remedi al alternatives (no action, monitoring, capping, and dredging). Monitoring was selected as the preferr ed alternative. One public comment was received, requesting a remedial action or nothing be done, rather than monitoring. After deliberation, the USEPA, FDEP, National Oceanic and Atmospheric Administra tion, and the Navy agreed to perform additional assessment because Hurricane Georges affected the area in the years following the initial sampling event. An additional remedial investigation was performe d in March 2000 to determine whether chemical constituents at Site 2 create adverse conditions fo r benthic communities. Data from the additional RI indicate that benthic communities in the near shor e environment have been adversely affected by Site 2 sediments that contain metals and SVOCs similar to those found in shoreline groundwater. Bioassays indicated that toxic chemicals are probably stressing the ecological system at two 150-foot by 150-foot areas. One area (DU08) is located approximately 16 0 feet from the seawall and another area is adjacent to the seawall near Port Operations (DU11).

PAGE 85

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 4-6 CTO 0030 The estimated volume of contamination, assuming a 1-foot depth, was 1,600 cubic yards. It was recommended in the Final RI Report Addendum that a FS be conducted to determine the most appropriate method for addressing the sediment. A Focused FS Addendum that evaluated four remedial al ternatives (no action, monitoring, capping, and dredging with off-site disposal) for the site was completed in October 2004. This report addresses sediment within the two 150-foot by 150-foot area s identified as having adverse effects in the 2004 RI Addendum. The Proposed Plan for the site stated t hat no action was the preferred alternative, and a public comment period was held from July 1, 2005 to A ugust 14, 2005. No comments were received from the public on the Proposed Plan. 4.3.2 Basis for No Action at OU3 In 1996, an RI was conducted to identify the nature and extent of contaminants in surface waters and sediments, and the influence of groundwater, as a resu lt of past disposal practices from the shore-based facilities (EnSafe, 1996b). The Focused FS evalua ted the RI, the baseline risk assessment, and the ecological risk assessment to develop preliminary re medial goals (PRGs) for OU3. The baseline risk assessment did not identify any unacceptable risk to human health, and no further action was required to protect human health under the current use. However, it was found that contam inated sediments pose an unacceptable risk to the be nthic organisms at OU3. 4.4 REMEDIAL ACTIONS FOR OU3 No action was selected as the preferred remedial action alternative for OU3. 4.4.1 Remedy Selection at OU3 The ROD for NAS Pensacola OU3 was finalized on September 30, 2005. The selected remedy was no action. The selected remedy poses no risk to current workers and site trespassers, and no additional risk to the ecosystem. The selected remedy protects human health and the environment by eliminating, reducing, and controlling risk throug h access restrictions and natural processes. Existing controls inherent to OU3 include a concrete seawall, limited access, and restrictions on use. Current site-access controls prohibit swimming, fishing, and crabbing, ther eby reducing the potential for direct human contact with site sediments and harvesting of aquatic specie s for consumption. In addition, Homeland Security Restrictions are in place and prohibit unauthorized boat traffic within 500 feet of the shoreline. Under the No-Action alternative, t he only adverse risks are to ecol ogical receptors, resident marine organisms, at the two 150-foot by 150-foot areas. At these two areas, sediment would remain in place and would attenuate according to natural biotic or physical processes. Organisms at Site 2 could

PAGE 86

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 4-7 CTO 0030 transform or degrade organic COCs to less toxic forms via bioprocesses. Intrinsic bioremediation, even of these persistent (organic) compounds, occurs naturally but slowly in sediments, and uses indigenous microorganisms and enzymatic pathway s of both aerobic and anaerobic processes. As natural sedimentation and/or transformation of the chemicals occur, other less opportunistic species in the bay may begin to move into the area naturally Although there are insufficient data to estimate natural attenuation rates, Acid Volatile Sulfide and Simultaneously Extracted Metals (AVS/SEM) analyses indicates that metals would not bioavailabl e at DU08 but are bioavailable in DU11. The No-Action alternative was selected because not di sturbing the sediments would allow the attenuation of contaminants through natural biotic or physical processes and if active remediation (e.g., excavation or dredging) conducted prevent the spre ading of COCs that would present an adverse risk to ecological receptors from the releasing of sediment-bound co ntaminants into the water column. The existing sediments could also be preventing contaminants in groundwater from infiltrating the surface water column. Heavily reduced sediment s are typically capable of removing inorganic and organic compounds through binding and reductive processes. The remedial objective for the remedial alternative is to protect the ecological environment where it is determined that toxic chemicals are probably stressing the system. This is occurring in the southeast portion of Site 2, one area (DU08) is located approxi mately 160 feet from the seawall and another area is adjacent to the seawall near Port Operations (DU11) Approximately 1,667 cubi c yards of contaminated sediment are located in these two areas. The expected outcomes of the se lected remedy were as follows: The Navy will retain the use of OU3, which will be consistent with the curr ent and expect ed military use of the area. Homeland security rest rictions prohibit unauthorized access. Natural sedimentation should be occurring in the area of concern and eventually bury the contaminated sediment. Sediments are also expected to continue to be remediated through natural attenuation, which should reduce current contaminants to below remedial goals. Sediments would remain in place, eliminating the risk of releasing sediment-bound contaminants into the water column, and contaminants infiltrating from groundwater may be prevented from entering the surface water as heavily reduced s ediments are typically capable of removing inorganic and organic compounds through binding and reductive processes.

Site 15 is accessible from the west by an unpav ed road and includes portions of the golf course, the golf course maintenance facilities, three concrete wash-down pads, two asphalt wash-down pads, a former pesticide/drum storage building, a removed UST, equipment storage buildings, and several in-use buildings. The site is surrounded by the golf course on its southern and western sides and Bayou Grande approximately 665 feet to the north. From 1963 to the present, fertilizer, pesticide, and he rbicide materials for application at the golf course have been stored and mixed at the golf course maintenance fac ility. Application equipment such as tractors, sprayer tanks, an d spreaders are also rinsed at the facilitys wash-dow n pads, which are located northeast of Building 2692 and northwest of Building 3447. Prior to the construction of the wash racks,

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 5-3 CTO 0030 cleaning the equipment at the asphalt wash-down pad re leased dilute rinsate solutions directly onto the surrounding ground surface, where the materials in filtrated the soil (Geraghty and Miller, 1984). In the past, a sink located outside of Building 3586 and a floor drain in a concrete pad north of the building collected pesticide and herbicide residue wastes and discharged them into a UST. The contents were periodically pumped out by a contracted agent before its removal in 1993. The UST was removed in 1993 and the contents of the tank were spread across the ground surface, approximately 200 feet northnorthwest of Building 3447 (EnSafe, 1999). 5.2.2 Land and Resource Use at OU4 Site 15 is located within the confines of the NAS Pens acola Golf Course. Surface cover in the vicinity of the site is dirt and/or grass (See Figure 5-1). The site is separated from the golf course by a perimeter border of oak and palm trees. Water hazards associated with the golf course are located 765 feet to the northeast and 425 west from the central part of the site. Bayou Grande is located approximately 665 feet north of the central part of the study area. Depth to groundwater ranges from 10 to 15 feet bl s, depending on precipitation, tidal influence, and ground surface elevation. Storm water management on the site is addressed through direct infiltration into the subsurface through the sandy surficial soil (EnSafe, 1997b). Groundwater flow generally mimics the peninsular topography (with flow to the northwest, north, and northeast towards Bayou Grande). Groundwater is not currently used as a potable water source at OU4 (CH2M Hill, 2006). The main source of potable wate r for NAS Pensacola is the Navy-owned well field located at NTTC Corry Station, which is located app roximately three miles north of NAS Pensacola on the northern (opposite) side of Bayou Grande. 5.3 HISTORY OF CONTAMINATION AT OU4 Contaminant types identified in soil samples collected at OU4 consisted of metals (particularly arsenic), total recoverable petroleum hydrocarbons (TRPH), VOCs, PAHs, and pesticides. Low concentrations of metals (particularly arsenic) and dieldrin/4,4-dic hlorodiphenyldichloroethylene (DDE) were detected in groundwater samples (EnSafe, 1999). Several inorganic and organic parameters exceeded preliminary remedial goals in soil samples. Based on the magnitude and frequency of the detection, arsenic and dieldrin remained the primary COCs in soil. Arsenic was detected across the ext ent of the site due to handling of various arsenic-based herbicides and pesticides, such as the common herbicide mono sodium methanarsonate. The two areas of greatest surface soil arsenic concentrations were identifi ed as the asphalt pad northwest of Building 2640 and the concrete pad west-northwest of Building 3586. Contam inated soil was also noted at isolated locations throughout Site 15 and north of the road in the old disposal area (EnSafe, 1999).

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 5-5 CTO 0030 5.3.1 Initial Investigation for OU4 The IAS report prepared by NEESA identified OU4, Site 15 as potentially posing a threat to human health or the environment due to contamination from past hazardous materials operations. According to the IAS report, pesticide rinsate was not sufficiently concentrated to threaten human health or the environment and further study was not recommended (NEESA, 1983). Therefore, environmental sampling and laboratory analyses were not performed, and the potential impact was not properly assessed. In 1984, Geraghty and Miller, Inc. conducted a Veri fication Study of the asphalt wash-down pad and pesticide storage area at OU4, Site 15. The results of the Verification Study confirmed the presence of arsenic and organic pesticide contaminants in the soil The presence of arsenic impacted groundwater at the site was documented by Geraghty and Miller during performance of a 1986 Characterization Study. Phase I of a Contamination Assessment/RI was con ducted in 1991 by Ecology and Environment, Inc. to identify principal areas and primary COCs, and to recommend if subsequent investigations were necessary. Investigation results indicated the presen ce of metals (particularly arsenic), TRPH, VOCs, PAHs, and pesticides in the soil. Low concentrations of metals (particularly arsenic) and pesticides (dieldrin/4,4-DDE) were detected in groundwater samples (EnSafe, 1999). 5.3.2 Basis for Taking Action at OU4 The hazard presented by potential exposure to the identified contaminants at Site 15 resulted in the performance of a baseline risk assessment. The baseline risk assessment used the Florida risk threshold goals, which is more conservative than USEPAs acceptable risk range and associated Risk Assessment Guidance for Superfund information (EnSafe, 1997b). The ILCR associated with the incidental ingestion of su rface soil by a hypothetical future resident (7E-5) and site worker (8E-6) exceeded the Fl orida target risk level of 1E-6. The ILCR associated with dermal contact with surface soil by a hypothetical future resid ent (2E-5) and site worker (7E-6) also exceeded the Florida target risk level. Both exceedances were primarily due to the presence of arsenic at 24 sample locations, dieldrin in two of the locations, and alph a-chlordane and BEQs in one location each. In addition, the ILCR associated with the incidental ingestion of groundwater by a hypothetical future resident in Areas 1 and 2 (5E-3 and 2E-3, respectively) and site workers (1E-3 and 5E-4, respectively) exceeded FDEPs target risk level. This was primarily due to the presence of arsenic (CH2M Hill, 2006). The HHRA identified arsenic, BEQ s, dieldrin, alpha-chlordane, and gamma-chlordane as COCs for surface soil, and arsenic and dieldrin as COCs for groundwater. The HHRA determined that 15 soil samples had a cumulative non-cancer HI from potential exposures to alpha-chlordane, arsenic, BEQs,

PAGE 94

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 5-6 CTO 0030 dieldrin, and gamma-chlordane in soil of less than 1. Th is is within the USEPA and FDEP target HI of 1 for current workers, trespa ssers, and future residents for industrial scenarios. Moreover, the HHRA determined that groundwater samples from 6 of 28 monitoring well locations had dieldrin or arsenic at concentrations which resulted in a cumulative HI of greater than 1, primarily due to the presence of arsenic. This is not within the USEPA and FDEP target HI of 1 for current wo rkers, trespassers, and future residents. The HHRA determined all 15 soil samples had a cumulative non-cancer HI from potential exposures to alpha-chlordane, ars enic, BEQs, dieldrin, and gamma-chlordane in soil of less than 1. This is less than the USEPA and FDEP target HI of 1 for cu rrent workers, tr espassers, and future residents for industrial scenarios. The ecological risk assessment selected the eastern cottontail rabbit and the American robin as endpoint wildlife species for the baseline risk assessments ecological component, as no endangered species were identified on site. Based on conservative assumptions, the risk evaluation indicates potential sub-lethal effects to these species from maximum detected co ncentrations of arsenic, mercury, and possibly pesticides in surface soil (EnSafe, 1999). Downgradient surface water, sediment, and biota (w ithin Bayou Grande and Wetland 65) were not at risk from the site, given their distance, the shallow groundwater quality adjacent to the water bodies, and the nature and limited extent of site-imp acted groundwater (EnSafe, 1999). Contaminants COCs related to each medium are presented in Table 5-2. TABLE 5-2 OU4 CONTAMINANTS OF CONCERN FIVE-YEAR REVIEW NAVAL AIR STATION PENSACOLA PENSACOLA, FLORIDA Medium Contaminants of Concern Soil Arsenic, BEQs, and dieldrin Groundwater Arsenic and dieldrin* Dieldrin was eliminated in the ROD because at that time, the dieldrin Florida Groundwater Guidance Concentration [FGGC]) was 0.1 g/L. OU4 groundwate r results originally indicated only one exceedance, monitoring well 15GS68 at 0.11 g/L. This value is considered equivalent to the FGGC when rounded to the same number of significant digits and subsequent sampling did not confirm the presence of dieldrin. Therefore dieldrin concentrations in groundw ater do not warrant further attention.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 5-7 CTO 0030 5.4 REMEDIAL ACTIONS 5.4.1 Remedy Selections at OU4 The ROD for NAS Pensacola OU4 was finalized on September 27, 2000. RAOs were developed based on data collected during the RI to aid in the develop ment and screening of remedial alternatives to be considered for the ROD. The purpose of the remedial action at OU4 was to reduce the unacceptable risks to human health and environment associated with exposure to the COCs in soil and groundwa ter. To meet these goals, two RAOs were identified. Table 53 lists the RAOs for OU4. TABLE 5-3 OU4 REMEDIAL ACTION OBJECTIVES FIVE-YEAR REVIEW NAVAL AIR STATION PENSACOLA PENSACOLA, FLORIDA Medium Contaminants Causing Unacceptable Risk Remedial Action Objectives Soil Arsenic, BEQs, and dieldrin Eliminate human health risk above HI=1. Groundwater Arsenic Monitor groundwater to ensure COCs are not migrating off-site, compliance with the performance standard: and institutional controls The remedial alternative for soil was selected to prevent future unacceptable risk due to exposure to arsenic, BEQ, and dieldrin contaminated soil. T he major components of the soil remedy include: Removing excess risk from the dermal and inge stion pathways for contam inated soil by removing contaminated soil above industrial goals through a removal action. Implementing institutional controls through t he LUCAP, restricting site use to industrial. Reviewing the institutional controls and certification in order to determine if they should remain in place or be modified to reflect changing site conditions.

PAGE 96

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 5-8 CTO 0030 The following components constitute the remedial action for OU4 to address the groundwater RAOs: Perform groundwater monitoring to ensure COCs are not moving off-site and monitor compliance with the performance standard for arsenic of 50 par ts per million. After continued attainment of the performance standard for tw o consecutive sampling events and concurrence with USEPA and FDEP, the monitoring program may be discontinued. Conducting a review to determine whether groundwater performance standards continue to be appropriate. Implementing institutional controls through the LUCAP to restrict use of groundwater from the surficial zone of the sand and gravel aq uifer within 300 feet of the site. Annual review/certification of institutional controls to determine if they should remain in place or be modified to reflect changing site conditions. 5.4.2 Remedy Implementation at OU4 Source removal activities were completed between April 26, 2002 and May 6, 2002. Five individual contaminated areas were consolidated into three excavation areas. A registered Florida land surveyor demarked the areas requiring excavation to a depth of 2 feet bls and two specific areas requiring excavation to the soil water table interface. Demark ed excavation areas were based on assessment data provided by CH2M Hill. Approximately 754 cubic yards of arsenic impacted soil was excavated and transported to the BFI Timberlands Landfill, located in Brewton, Alabama, for disposal. Prior to completion of excavation activities, representative soil samples were collected fr om the selected off-site backfill source at the Sand & Dirt, Inc. facility. The soil was analyzed to ensure suitability for use at the site. One sample was collected from the proposed backfill borrow pit and anal yzed for VOCs, SVOCs, pesticides, herbicides, metals, PCBs, TRPH, and pH. The analytical results indicated that with the exception of metals, the targeted parameters were not detected in the sample collected from the proposed ba ckfill borrow pit. Arsenic was detected above the Florida residential di rect exposure SCTL, but below the site-specific cleanup goal of 21.93 mg/kg. Therefore the backfill was accepted as clean fill (CH2M Hill, 2006). The ROD for Site 15 requires monitoring of groundwate r to ensure that COCs are not moving off-site. The remedial goal for arsenic, established in the Site 15 ROD, is 50 g/L. Baseline groundwater sampling was conducted in November and December 2001, and two semiannual sampling events were completed in June 2002 and January 2003. In preparation of LTM, the monitoring wells at Site 15 were evaluated to

PAGE 97

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 5-9 CTO 0030 document construction deficiencies. As a result, 14 monitoring wells that were damaged or improperly constructed were abandoned. Five were replaced (15GR03R, 15GR04R, 15GR65R, 15GR66R, and 15GS69R), and one new monitoring well (15GR07R) was installed adjacent to a previously abandoned monitoring well (CH2M Hill, 2003). 5.4.3 System Operation/O&M at OU4 The cost for the selected remedy does not include O&M. 5.4.4 Long-Term Groundwater Monitoring at OU4 The ROD specifies collection of groundwater samples from monitoring wells 15GR03R, 15GR04R, 15GR07R, 15GR065R, 15GR66R, 15GS68, 15GS69R 15GS70, 15GS71, 15MW72, 15MW73, 15MW74, 15MW75, and 15MW76 on a semiannual basis. The resu lts of the baseline groundw ater monitoring event conducted in November through December 2001 indicated the presence of arsenic at concentrations ranging from 70 g/L to 510 g/L. The arsenic concentrations detected during the June 2002 and January 2003 semiannual sampling events ranged from 66 g/L to 650 g/L, and 53 g/L to 630 g/L, respectively. Arsenic concentrations detected in groundwater samples collected semiannually from January 2004 to October 2007 ranged from non-detect to 160 g/L. However, the monitoring well with the highest previous concentrations (15GR03R) was not sampled from April 2005 to September 2008 because the well could not be located (Aerostar, 2008a). Aerostar installed a replacement monitoring well, 15GR03RR in July 2008 and reinstated groundwater sampling at this location. Following the September 2009 sampling event, Aerostar noted in the Year 2009 First Semi-Annual Groundwater Monitoring Report that arsenic concentrations at monitoring well locations 15GR07R, 15GS68, 15GS69R, 15GS70, 15GS71, 15MW72, 15MW73, 15MW74, and 15MW75 were below its cleanup target level for five consecutive sampling events and below the remedial goal for more than five years. Aerostar recommended these monitor wells to be removed from future sampling events. The regulatory agencies agreed (December 31, 2009) and Aerostar continued sampling of 15GR03RR, 15GR04R, 15GR65R, and 15GR66R to monitor extent and migration of arsenic. Trend analysis for the COCs for groundwater at NA S Pensacola was performed using the Mann-Kendall test (ProUCL Version 4.1.00 [Lockheed Martin Enviro nmental Services, 2010]) at a 95 percent confidence level and OU4 groundwater sample data collected from 2004 to 2011 (Appendix D). The Mann-Kendall test is used because it does not assume any parti cular distributional form and accommodates values below the detection limit by assigning them a common value ( the detection limit).

PAGE 98

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 5-10 CTO 0030 The concentration of arsenic at monitoring well location 15GR03RR since September 2008 has ranged from 65 to 870 g/L and exceed the remedial goal for arsenic of 50 g/L, established in the Site 15 ROD and the current federal and state MCL of 10 g/L. The Mann-Kendall trend analysis suggest no trend is present at a 95 percent confidence level. The concentration of arsenic at monitoring well location 15GR04R, which has been sampled 10 times since September 2008, has ranged from 4.8 to 20 g /L and did not exceed the remedial goal for arsenic of 50 g/L, but exceeded the current federal and st ate MCL of 10 g/L in 6 of the 10 groundwater samples. This monitoring well has not been sampled since March 2010. The Mann-Kendall trend analysis suggests no trend is present at a 95 percent confidence level. The concentration of arsenic at monitoring well location 15GR65R, which has been sampled 15 times since September 2008, has ranged from less than 3. 0 g/L to 14 g/L and did not exceed the remedial goal for arsenic of 50 g/L, but exceeded the current federal and state MCL of 10 g/L in 4 of the 15 groundwater samples. The Mann-Kendall trend analysis suggest no trend is present at a 95 percent confidence level. The concentration of arsenic at monitoring well location 15GR66R, which has been sampled 15 times since September 2008, has ranged from 10 to 38 g/L and did not exceed the remedial goal for arsenic of 50 g/L, but equaled or exceeded the current federal and state MCL of 10 g/L in each of the 15 groundwater samples. The Mann-Kendall trend analysis suggest a downward trend is present at a 95 percent confidence level. Since March 2008, arsenic has been detected only one time at monitoring well location 15GS70 at a concentration that exceeds the curr ent federal and state MCL of 10 g /L. Also, since March 2008, arsenic has not been detected or was less than the current f ederal and state MCL of 10 g/L at eight monitoring well locations (15GR07R, 15GS68, 15GS69R, 15GS71, 15MW72, 15MW73, 15MW74, and 15MW75). Monitoring well locations 15GR07R, 15GS68, 15GS69R, 15GS70, 15GS71, 15MW73, and 15MW75 have not been sampled since September 2009. Monitoring well 15MW76 has not been located since March 2005. The cost expended to date for capital costs, O&M costs, and remedial action is $1,331,021. 5.5 PROGRESS SINCE THE LAST FIVE-YEAR REVIEW Since the last Five-Year Review, groundwater monitoring has continued at OU4. Additionally, institutional controls remain in place and annual inspecti ons and certifications have been conducted.

PAGE 99

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 5-11 CTO 0030 No issues were identified during the previous Five-Year Review; therefore, there were no follow up actions. 5.5.1 Protectiveness Statements from the Last Review Based on the results of the 2008 Five-Year Review, the remedy was expected to be protective of human health and the environment upon attainment of groundw ater cleanup goals through natural attenuation. 5.5.2 Status of Recommendations and Follow-up Actions from Last Review No recommendations or follow up actions were identified during the previous Five-Year Review. 5.6 FIVE-YEAR REVIEW PROCESS This is the second Five-Year Review for OU4. Members of the NAS Pensacola Partnering Team were notified of the initiation of the Five-Year Review in January 2012. The Five-Year Review was led by Gerald Walker of Tetra Tech, the NAVFAC SE Navy CLEAN Contractor, and included other Tetra Tech staff. Patty Marajh-Whittemore of NAVFAC SE, Greg Campbell of NAS Pensacola Public Works Department, Tim Woolheater of U SEPA, David Grabka of FDEP, and Sam Naik of CH2M Hill assisted in the review. The review included the following components: Document Review Data Review Site Inspection Five-Year Review Report development and review 5.6.1 Document Review This Five-Year Review consisted of a review of rele vant documents including the ROD, Interim Remedial Action Report, Groundwater Monitoring Plan, semiannual monitoring reports, a nd applicable federal and state statutes. 5.6.2 Data Review and Review of COC Data for Groundwater The results presented in the Interim Remedial Ac tion Report indicate that arsenic impacted soil at concentrations greater than the remedial goal were removed and replaced with clean backfill. Graphs developed using the concentrations of arsenic provid ed from data in monitoring reports summarizes the analytical results of MNA of groundwater; suggestin g that arsenic concentrati ons have decreased. With

Trend analysis results are provided in Appendix D. Review of the March 2012 groundwater analytical data indicates that arsenic concentrations exceeded the ROD specified remedial goal of 50 g/L and the current federal and state MCL of 10 g/L at monitoring well location 15GR03RR (110 g/L). The arsenic concentration at monitoring well 15GR66R (16 g/L) exceeded the current federal and state MCL of 10 g/L. 5.6.3 LUC Inspections LUC inspections were conducted annually at OU4 during the period under review. The inspections noted no problematic observations. 5.6.4 Site Inspection and Interviews An inspection was conducted at the site on May 3, 2012 by Tetra Tech and NAS Pensacola personnel. The purpose of the inspection was to assess the pr otectiveness of the remedy and condition of the monitoring wells. Because surficial soil with arsenic concentrations exceeding the remedial goal was removed, fencing the site was not warranted. Monitoring wells 15GGR01 and 15MW76 were missing at the time of the inspection and need to be replaced. The remainder of the monitoring wells were accessible and in good condition. The institutional controls that are in place include the restriction of groundwater use within 300 feet of the site. At the time of the inspection, institutional controls were found to be adequate, and use of groundwater was not observed. Roadways within OU4 appeared adequate, and there were no apparent signs of vandalism or trespassing. An interview was conducted on May 2, 2012 with Greg Campbell, Environmental Engineer for NAS Pensacola. According to the interview, Mr. Camp bell indicated he is well informed about the sites activities and progress, and was not aware of any comm unity concerns regarding the site or its operation, or of any incidents such as vandalism, trespassing or emergency responses at the site. The interview forms are presented in Appendix E. Mr. Campbell indicated annual LUC inspections are performed. In addition, complaints, violations, or other incidents related to the site requiring a re sponse by his office have not occurred. Future construction of a warehouse is planned for the site.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 5-13 CTO 0030 5.6.5 ARAR Level Changes The following standards were identified as chemical-spec ific ARARs in the ROD. They were reviewed for changes that could affect protectiveness: Safe Drinking Water Act MCLs (40 CFR 141.11) Safe Drinking Water Act MCLGs (40 CFR 141.50 141.51) Florida GCTLs, Chapter 62-777, F.A.C. Florida SCTLs, Chapter 62-777, F.A.C. Florida Drinking Water Standards, Monitori ng and Reporting, Chapter 62-550, F.A.C. Florida Ground Water Classes, Standards and Exemptions, Chapter 62-520, F.A.C. Contaminant Cleanup Target Levels, Chapter 62-777, F.A.C. (Amended 4/17/05), Contaminated Site and Cleanup Criteria, Chapter 62-780, F.A.C., and Brownfie lds Cleanup Criteria, Chapter 62-785, F.A.C. were promulgated after the ROD. These new criteria need to be considered to determine if the remedy is still protective. Chapter 62-777, F.A.C. provides GCTL s for contaminants without MCLs per Chapter 62-550, F.A.C. The CTLs in Chapter 62-777, F.A.C. do not affect the protectiveness of the remedy. Chapter 62-780, F.A.C. provides rules for the a ssessment and cleanup of non-petroleum sites with contaminants that have been released or discharged into the environment and Chapter 62-785, F.A.C. provides rules for assessment and cleanup of Brow nfields sites. Rules promulgated per Chapter 62-780, F.A.C. and Chapter 62-785, F.A.C. do not affect the protectiveness of the remedy. Since signing the ROD for OU4 on September 27, 2000, changes to federa l regulations in 2002 and 2006 and to Florida regulations in 2005 lowered the MCL for arsenic in groundwater from 50 to 10 g/L. On January 22, 2001, the USEPA adopted a new MCL for arsenic in drinking water at 10 g/L, replacing the old standard of 50 g/L. The USEPA rule beca me effective on February 22, 2002 and became enforceable to water systems on January 23, 2006. Floridas drinking water standards are contained in Chapter 62-550, F.A.C. Floridas primary drinki ng water standards, which are health based, are described in Rule 62-550.310, F.A.C. Florida changed its MCL for arsenic from 50 g/L to 10 g/L on January 1, 2005. This change in the federal and state MCL for arsenic is being implemented in a draft ESD. There have been no other changes in Safe Drinking Water Act and Chapter 62-550, F.A.C. MCLs that may affect the protectiveness of the remedy. The following standards were identified as location-s pecific ARARs in the ROD. They were reviewed for changes that could affect protectiveness:

No further evaluation is necessary. The following standards were identified as action-specific ARARs in the ROD. They were reviewed for changes that could affect protectiveness: Florida Storm Water Discharge Regulations, Chapter 62-25, F.A.C. Florida Water Well Permitting and Construction, Chapter 62-532, F.A.C. The storm water regulation only applied during soil excavation which was completed in 2002. No further evaluation is necessary. The sections covering General Provisions for Water Well Permitting and Construction and Abandonment of Water Wells in 62-532, F.A.C. were repealed October 7, 2010. Monitoring well installation and abandonment are now addressed in the FDEP Monitoring Well Design and Construction Guidance Manual, 2008. The use of the guidance will not affect the protectiveness of the remedy. 5.7 TECHNICAL ASSESSMENT 5.7.1 Question A: Is the remedy functioning as intended by the ROD? The review of documents, ARARs, risk assumptions, and the results of the site inspection indicate that the remedy is functioning as intended by the ROD. Remedial Action Performance: Contaminated soil was removed from Site 15 and replaced with clean backfill. Monitored natural attenuation of gr oundwater contaminants is being conducted. Early Indicators of Potential Remedy Failure: None, the source of the contaminants has been removed and natural attenuation monitoring is being conducted. Implementation of Institutional Controls and Other Measures: The reporting and certification requirements for the LUCs are incorporated into the LUCAP between the Navy, USEPA, and FDEP. Site 15 will be available for industri al use. Residential use of the site would be prohibited, and the Navy would perform periodic site inspections and ensure the LUCs are being properly maintained and administered. Groundwater use is prohibited within 300 feet of the site. The Navy will conduct an annual

Exposure Assumptions: There have been no changes in the physical conditions of the site that would affect the protectiveness of the remedy. Changes to Standards and To Be Considered: ARARs and TBCs considered during preparation of the ROD were reviewed to determine changes to standard s since the remedy was implemented. The arsenic MCL per the Safe Drinking Water Act and Chapter 62 -550, F.A.C. has been changed from 50 g/L, which is the Performance Standard in the ROD, to 10 g/L. Changes in Exposure Pathways: No changes in the site conditions or land use that affect exposure pathways were identified as part of the Five-Year Review. Exposure to the site groundwater is still restricted by the LUC. Changes in Toxicity and Other Contaminant Characteristics: There have been no changes in human health or ecological toxicity criteria that would impact protectiveness of the remedy. Changes in Risk Assessment Methodologies: Changes in risk assessment methodologies since the time of the ROD do not call into questi on the protectiveness of the remedy. 5.7.3 Question C: Has any other information come to light that could call into question the protectiveness of the remedy? No additional information has come to light that calls into question the protectiveness of the remedy. 5.8 ISSUES Issues were discovered during the Five-Year Review and are noted in Table 5-4.

FDEP c oncurred with the ROD on March 10, 2006. Implementation of the remedial ac tions at OU11 began in 2006. The initial Five-Year Review for OU11 was completed in 2008. This Five -Year Review consists of an approximate five-year period of data and provides a status update for OU11, Site 38 Building 71 and 604 (hereinafter Site 38), surrounding areas, and the IWTP sewer line. This Five-Year Review for Site 38 is being conducted because hazardous substances, pollutants, or contami nants remain at the site above levels that allow for unlimited use and unrestricted exposure. 6.1 SITE CHRONOLOGY A list of significant Site 38 historical events and relevant dates is provided in Table 6-1.

Building 71, shown on Figure 6-1, was used from 1935 to the late 1970s for aircraft paint stripping and painting operations, and consisted of a steel-framed structure with metal siding on a 10 to 14 inch thick concrete slab. The building was approximately 100 feet wide by 160 feet long and approximatel y 35 feet high. An interior concrete block wall divided it into a northern half, curbed with concrete in several places, and a southern half enclosing 10 dip tanks. The building was demolis hed in 1993. Building 71 was used from 1935 to the late 1970s for aircraft paint stripping and painting operations. From 1980 to 1989, hazardous waste was stored on the north side of Building 71, which was permitted for hazardous waste storage in J anuary 1985 by the FD EP (formerly the FDER) (NEESA, 1985). Waste stored during this period reportedly consisted of so lvents, acids, caustics, ox idizers, and liquid and nonliquid toxic materials (E&E, 1992). Wastes from various operations at Site 38 (including paint stripping) were discharged to Pensacola Bay until the IWTP was built in 1973. Wastes previously entered the IWTP sewer line by gravity feed and force main without any pretreatment or segregation. Except fo r one 18-foot section constructed of 8-inch diameter polyvinyl chloride (PVC) pipe, the lines in th is area are constructed of 8 to 12 inch diameter vitrified clay with hub and spigot joints. Building 3435 north of the Building 71 area, housed the lift station for the force main. The interconnected gravity lines, which previously served operations at Building 604

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 6-3 CTO 0030 and Building 71, flow to the lift station at Building 3 435. The force main extends northeast from the lift station where it eventua lly discharged to the IWTP (EnSafe, 2005a). Building 604, shown on Figure 6-1, was an irregularl y shaped, brick/masonry structure built in 1937. NADEP metal plating operations were located in Bu ilding 604 until it was closed in May 1996 (EnSafe, 2005a). Initial plating operations were conducted in the we stern portion of Building 604 from approximately 1960 until the shop was demolished ar ound 1970 (NEESA, 1983). Plating ope rations were subsequently transferred to a larger plating shop, constructed in 1970, in the southwest portion of Building 604. Three cadmium plating lines and a magnesium treatment line were located in the plating shop. Chromium was used in the magnesium treatment process. NEESA (1983) reports that 50-gallon tanks containing chromium solutions were drained approximately once per month; larger tanks were present but were drained less frequently. Reportedly, these tanks were emptied into sewer lines that discharged into Pensacola Bay (NEESA, 1983). Cyanide solutions were also used in the plating process, and prior 1962, cyanide waste was disposed in the sanitary sewer. Cyanide and chromium wastes that were dumped into the sewer system were routed to bypass the treatment plant and flowed untreated into Pensacola Bay. Hazardous materials were stored on the second floor of Building 604. 6.2.2 Land and Resource Use at OU11 Site 38 is located north of Pensacola Bay along Radf ord Boulevard, in the s outheastern portion of the NAS Pensacola facility. The site, form erly an approximate 12 acre industrial area, was primarily paved or covered by buildings. Building 71 was used from 1935 to the late 1970s for aircraft paint stripping and painting operations. Wastes from various operations including paint stripping, were discharged to the Pensacola Bay until the IWTP was built in 1973. Building 604 housed the NADEP metal plating operations until it was closed in May 1996. This two-story, irregularly shaped, brick masonry structure was built in 1937 as a hangar on the west side of East Avenue in the old Navy yard. The area is generally flat with land surface elevatio ns approximately 3 to 8 feet above mean sea level. Rainfall is addressed via an existing storm water management system (EnSafe, 2005a). Groundwater flow generally mimics the peninsular topography and flows to the south towards Pensacola Bay. Groundwater is not used as a potable water source at OU11 (EnSafe, 2005a). The main source of potable water for NAS Pensacola is the Navy-owned well field located at NTTC Corry Station, which is located approximately three miles north of NAS Pe nsacola on the northern (opposite) side of Bayou Grande.

PAGE 108

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 6-4 CTO 0030 Many of the buildings in the Site 38 area were damaged in 2004 by Hurricane Ivan and subsequently demolished. The Building 71 area is currently a recreati onal area that is used for ceremonial activities. The Building 71 area is mostly grass and shrubbery bordered by concrete sidewalks, a small parking area is on the northern portion of the site for parking. Much of the Building 64 area is a natural area and parts of the southern end of the site is used for pa rking. Future uses for Site 38 are limited to commercial/industrial and recreational land use. T he projected future land use for these areas is designated as green space area that includes a wa lking trail along the Pensacola Bay waterfront. 6.3 HISTORY OF CONTAMINATION Site 38 was found to have contaminated soil and groundwater at Buildings 71 and 604 that were associated with the IWTP sewer line areas. Soil dat a generated by various investigations at Site 38 identified constituents in surface an d subsurface soil above Floridas applicable Chapter 62-777, F.A.C. residential and industrial direct exposure SC TLs, and Leachability to Groundwater SCTLs. Contaminants identified in the surface soil in the Building 71 study area included inorganics, SVOCs, pesticides, and PCBs. Soils that contained organic exceedances of industrial direct exposure and Leachability to Groundwater SCTLs were limited in areal extent, and pesticide and PCB exceedances were limited to two locations. Pesticide detections in these areas are likely the result of pesticide application. Contaminants identified in the subsurfa ce soil included inorganics, SVOCs, pesticides, and VOCs, with much of the contamination underneath the bu ilding. The contaminants are likely the result of past paint stripping and metal refinishing activities at Building 71. Contaminants identified in the surf ace soil in the Building 604 study area included inorganics, SVOCs, pesticides, and PCBs. The exceedances of indu strial direct exposure and Leachability to Groundwater SCTLs were limited in areal extent. Pesticide detections in these areas are likely the result of pesticide application. Contaminants identified in the subsurfa ce soil included inorganics, SVOCs, pesticides, and VOCs. The contaminants are likely the result of past plating activities at Building 604. 6.3.1 Initial Investigation at OU11 The hazard presented by potential expo sure to the contaminants identified at Site 38 initiated a baseline risk assessment in accordance with USEPA and FDEP guidance. Th e results of the baseline risk assessment prompted the performance of a preliminary risk evaluation of potential risks from site constituents to human receptors at the site. The ris ks calculated in a preliminary risk evaluation are derived by a comparison of exposure concentrations to CTLs. These CTLs are derived using default exposure assumptions established by the USEPA and FDEP. There ar e no deviations between the Navy and the regulatory agencies regarding those expo sure assumptions or pathways defined by the regulatory agencies for residential and industrial exposures. Floridas acceptable target risk is 1E-6 (1 in

The USEPAs acceptable target risk range is 1E-4 to 1E-6 (1 in 10,000 to 1 in 1,000,000). Preliminary risk evaluation is the risk evaluation tool on which remedial decisions are based, and was conduc ted to refine the list of potential contaminants to actual COCs using guidance by USEPA and FDEP. 6.3.2 Basis for Taking Action at OU11 The RI included a baseline risk assessment to deter mine potential risks to human health from exposure to contaminants in soil and groundwater. Contaminants were detected in concentrations causing unacceptable risk for future residents within various media at Site 38. COCs related to each medium are summarized in Table 6-2.

Contaminant concentra tions in groundwater were compared against promulgated regulatory criteria per the Safe Drinki ng Water Act, Chapter 62-55 0, F.A.C. and Chapter 62777, F.A.C., and to evaluate potential unacceptable risk due to use/consumption of the water and if natural attenuation may occur. Contaminants exceedi ng any of these regulatory criteria were listed as COCs. It was determined there are no unacceptable risks to ecological receptors asso ciated with surface soil contamination, primarily because natur al terrestrial habitat features were not present in or around Site 38. The only terrestrial receptors are shorebirds that peri odically visit the area. In addition, most of the site was formerly covered by asphalt, concrete, or build ings, and contamination within former small grassy areas was minimal. The removal of the top 2 feet of soil across Site 38 that contained COCs makes the exposure pathway for surface soil contamination incomplete.

RAOs were developed from the data collected during the RI to aid in the development and screening of remedial alternatives to be considered for the ROD. The goals of the selected so il and groundwater remedies at OU11 are to protect human health and the environment by eliminating, reducing, or controlli ng hazards posed by the site and to meet ARARs. Table 6-3 lists the RAOs for OU11.

Five remedial alternatives were considered for soil at Site 38. Of the alternat ives evaluated, the selected remedial action was Soil Alternative S4: excavation of i ndustrial direct exposure hot spots (3X industrial direct exposure SCTLs) and leachability to groundwater criteria exceedances with off-site disposal and LUCs to prevent residential use. The major components of Alternative S4 are listed below: Exposed surface soils exceeding three times the Florida industrial direct exposure SCTLs and leachability to groundwater SCTLs to be excavated and disposed of at an appropriate disposal facility. Maintenance of existing asphalt and co ncrete paved areas covering areas.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 6-9 CTO 0030 LUCs to prohibit use of the site for residential or residential-like uses and prohibit excavation and removal of subsurface soil unless prior writt en approval is obtained from the Navy, USEPA, and FDEP. Three remedial alternatives were considered for gro undwater at Site 38. Of the alternatives evaluated, the selected remedial action was Groundwater Alternative G2: natural attenuation, LUCs, and groundwater monitoring to address contaminants in groundwater. The major components of Alternative G2 are listed below: MNA. LUCs to prevent access and prohibit all use of groundwater from the surficial aquifer underlying the site without prior written approval from the Navy, U SEPA, and FDEP, and maintain the integrity of any existing or future monitoring or remediation system. The remedy was selected for the following reasons: Except for the areas identified for removal, detected concentrations of COCs remaining in soil do not present an una cceptable threat to human health or the environment assuming that only industrial and/or commercial uses are permitted at Site 38 and the existing caps are maintained. Because of Hurricane Ivan damage, the Navy removed the buildings and associated parking lots. Surface soil areas identified as exceeding industrial direct exposure SCTLs were to be removed and replaced with clean fill to prevent unacceptable exposure. Although contamination is present in groundwa ter at concentrations greater than federal and Florida CTLs, detected concentrations are relatively low and do not present an unacceptable threat to human health or the environment un der the groundwater use restrictions to be implemented as part of the selected remedy. The contaminant plume is small and stable and confined to the shallow aquifer, and there is no evidence of ongoing contaminant migration. 6.4.2 Remedy Implementation at OU11 According to NAS Pensacola personnel, the building structures, parking lot surface and surficial soil at Site 38 were removed in 2004 during the cleanup of hurricane damaged structures and related debris. However, the contractor that performed the wo rk did not adequately document the source removal

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 6-10 CTO 0030 activity; however, waste disposal manifests documenti ng the volume of soil removed are available. Below is a description of the cleanup ac tivities conducted at Site 38. Building 604: Building 604 was demolished and contam inated soil that was identified during the RI to occur from the land surface to 2 feet bls was removed and disposed of between February and March 2006. The soil excavation boundaries and land surface elevations prior to excavation, after excavation and upon final grade of backfill were not surveyed at the Building 604 area; however, Navy personnel conducted periodic inspections to ensure that excavation boundaries and depths occurred as per the contract specifications. A sample was collected from the excavated soil and analyzed utilizing the TCLP, The results indicated that the soil was a non-hazardou s waste. Confirmation samples were not collected for chemical analysis. The contractor placed 2 feet of clean backfill into the excavation pit at the Building 604 area, then re-graded and grass/seeded the area. The clean backfill was not tested for any chemical parameters prior to being placed into the excavation pit. Building 71: Following Hurricane Ivan in 2004, the on site buildings and hurricane debris was removed. Contaminated soil from the land surf ace to 2 feet bls was also removed and disposed of. Four soil samples were collected from the excavated soil an d analyzed utilizing the TCLP; the TCLP analytical results indicated that the soil was a non-hazardous waste. Confirmation samples were not collected for chemical analysis. The soil excavation boundaries and land surface elevations prior to excavation, after excavation, and upon final grade of backfill were survey ed at the Building 71 area The contractor placed 2 feet of clean backfill into the excavation pit, t hen re-graded and sodded the area. The backfill was tested for a hazardous waste utilizing the TCLP test prior to being placed into the excavation pit. The soil was found to be non-hazardous and could be disposed of at a RCRA Subtitle D landfill. However, because totals analysis was not conducted for VO Cs, SVOCs, pesticides, PC Bs, and metals, it was determined that the analysis did not meet FDEP an d USEPA requirements of determining whether the backfill soil was "clean" (e.g., did not contain constituents at concentrations that would exceed regulatory screening criteria for direct exposur e or leachability to groundwater). In late 2008, as part of a larger water front reuse project the Building 71 area was extensively landscaped and a ceremonial pavilion was constructed. In July 2009, Tetra Tech on behalf of the Navy completed a supplemental confirmation soil sampling event at OU11, Site 38. The study was conducted to determine if the top 2 feet of soil was removed in the specific areas identified in the ROD; if the t op 5 feet of soil was removed in the specific areas identified in the ROD; and to determine if clean fill material was used as a replacement for the removed soil. The study included collection of 27 soil samples including si x soil samples of the fill material to verify that clean fill was used on site. The sa mples were analyzed for select parameters and a specific dieldrin risk

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 6-11 CTO 0030 evaluation/discussion was completed. The study reco mmendations indicated that the concentrations of the COPCs detected in the soil samples met the criteria for No Further Action to achieve the objectives of the selected remedy in the final ROD. Additionally asphalt and the soil backfill at Site 38 provide an effective cover to mitigate direct contact with the COPCs that remain at the site as was the intent of the selected remedy of LUCs that were described in the fi nal ROD. Therefore, the soil excavation remedy is believed to be protective and the OU11 Remedial Design should be completed to include implementation of the LUCs. A UFP-SAP was submitted in April 201 0 for conducting natural attenuation monitoring at Site 38 per the ROD (Tetra Tech, 2006b). Implem entation of the Site 38 UFP-SAP is pending regulatory concurrence of the Groundwater Moni toring Plan for OU11, Site 38. Also, ba sed on comments provided by the USEPA, more current groundwater data is re quired at adjacent IR Sites 45 and 46 to support the respective Draft Proposed Plans. The NAS Pensacola Partnering Team agreed during their meeting on December 13 and 14, 2011 that the Navy would amend the UFP-SAP for OU11, Site 38 to include collectin g a round of groundwater samples from monitoring wells at Sites 45 and 46 to assess the current conditions of COCs at Site 45 and Site 46. The monitoring has not be en initiated because regulatory concurrence has not been received. To date no cost associated with si te remediation have been expended. 6.5 PROGRESS SINCE THE LAST FIVE-YEAR REVIEW A draft Land Use Control Remedial Design (LUC RD) for soil and groundwater was submitted in December 2011. A response to regulatory comments is being prepared. 6.5.1 Protectiveness Statements from the Last Review The 2008 Five-Year Review concluded that the remedy is expected to be protective of human health and the environment upon attainment of groundwater cle anup goals through natural attenuation. In addition, the previous Five-Year Review stated that in th e interim, exposure pathway s that could result in unacceptable risks are being controlled and instituti onal controls are preventing exposure to, or the ingestion of, contaminated groundwater. Issues identified in the 2008 Five-Year Review and actions taken are summarized in Table 6-4.

The confirmation sa mples were collected to determine if the contaminated soil that exceeded three times the Flori da industrial direct exposure SCTLs and/or leaching to groundwater SCTLs has been removed from the Building 604 area north of Radford Boulevard as specified in the ROD. The confirmation soil sampling results indicate that the COCs detected in the soil samples at sampling locations BT38, BT41, BT42, SS26, and S78S met the criteria for No Further Action to achieve the objectives of the selected remedy in the final ROD (Tetra Tech, 2006a). Additionally, asphalt and the soil backfill at Site 38 provide an effect ive cover to mitigate direct contact with the COCs that remain at site as was the intent of the selected re medy of LUCs that were described in the final ROD. 6.5.2.2 Follow Up Actions Taken for Item 2 from Table 6-5 A Groundwater Monito ring Plan and UFP-SAP for a natural attenuati on groundwater moni toring program are being prepared.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 6-14 CTO 0030 6.6.2 Data Review Source removal activities were conducted at OU11, Site 38 in conjunction with cleanup of hurricane related debris, and clean fill was placed in the excavat ed areas to limit direct exposure to soil containing the COCs remaining in subsurface soils at the si te. Monitoring of natural attenuation of groundwater quality has not been initiated. The Navy is preparing documentation for the source removal activity at Site 38. 6.6.3 LUC Inspections LUC inspections were conducted annually at OU11 during the period under review. The inspections noted no problematic observations. 6.6.4 Site Inspection and Interviews Inspections at the site were conducted on May 3, 20 12, by Tetra Tech personnel. The purpose of the inspection was to assess the prot ectiveness of the remedy, including general site condition and condition of the monitoring wells. At the time of the inspecti on, institutional controls appeared to be adequate, and use of groundwater was not observed. Roadways wi thin Site 38 appeared adequate, and there were no apparent signs of vandalism or trespassing. Since surficial soil with contaminant concentrations above the remedial goal were reportedly removed, fencing the site was not warranted. Existing moni toring wells were accessible and in good condition. Many monitoring wells at the Building 604 return to nature area were not present and were either abandoned or covered by fill. However, new replacement monitoring wells are to be installed for the natural attenuation monitoring program. Therefore, defi ciencies were not noted during the site inspection. An interview was conducted with Greg Campbell, Environmental Engineer for NAS Pensacola, on May 2, 2012. According to the interview, Mr. Campbell indicated he is well informed about the sites activities and progress, and was not aware of any comm unity concerns regarding the site or its operation, or of any incidents such as vandalism, trespassing, or emergency responses at the site. The interview forms are presented in Appendix F. Mr. Campbell indicated annual LUC inspections are performed. In addition, complaints, violations, or other incidents related to the site requiring a response by his office have not occurred.

They were reviewed for changes that could affect protectiveness: Safe Drinking Water Act MCLs (40 CFR 141.111.16) Safe Drinking Water Act MCLGs (40 CFR 141.5041.51) Safe Drinking Water Act Secondary Drinking Water Standards (40 CFR 143) Cancer Slope Factors (CSFs) (Integrated Risk Information System) Reference Dose Factors (RfDs) (Integrated Risk Information System) Florida SCTLs, Chapter 62-777, F.A.C. Florida Ground Water Guidance Concentrations Florida Drinking Water Standards, Monitori ng and Reporting, Chapter 62-550, F.A.C. Ground Water Classes, Standards, and Exemptions, Chapter 62-520, F.A.C. Since signing the ROD for OU11 in October 5, 2006, there have not been any changes to the above regulations that affect the protectiveness of the remedy. The soil criteria in the selected remedy included meeting industrial direct exposure SCTLs and leachability to groundwater criteria. These criteria are listed on Tables 2-1 and 2-2 of the ROD. The values in the table were compared to the current version of Chapter 62-777, F.A.C., and no differences were found. The remediation goals are protective. The Remedial Goals in Table 2-3 from the ROD incl ude CTLs and MSWCTLs. The values in the table were compared to the current version of Chapter 62 -777, F.A.C. In the absence of an MSWCTL, the water quality criteria for Class III Marine Waters in C hapter 62-302, F.A.C. were used. A few differences were noted as summarized in Table 6-6. The ROD values for phenanthrene and copper are more restrictive than the current values, so there is no change in the protectiveness is the current values are used. The ROD value for cadmium is slightly greater than the current value, so there may be sl ightly less protectiveness. The natural attenuation monitoring program has not been implemented.

The soil excavation is complete, so the RCRA, DOT, Florida Stormwater, Florida Hazardous Substance, and Florida Hazardous Waste are no longer pertinent and were not evaluated further. The groundwater monitoring program has not been implemented, so t he USEPA Monitored Natura l Attenuation Guidance was not evaluated. The sections covering General Pr ovisions for Water Well Permitting and Construction and Abandonment of Water Wells in Chapter 62-532, F.A.C. were repealed October 7, 2010. Monitoring well installation and abandonment are now addressed in the FDEP Monitoring Well Design and Construction Guidance Manual, 2008. 6.7 TECHNICAL ASSESSMENT 6.7.1 Question A: Is the remedy functioning as intended by the ROD? LUCs appear to be successful in preventing exposure to contaminated groundwater; therefore, this portion of the remedy is functioning as intended. MNA has yet to be initiated. Remedial Action Performance: Surface soil containing COCs were removed from Site 38 and replaced with clean backfill. MNA of the COCs remaining at the site has not been initiated. System O&M: There are no active remediation systems at OU11, therefore no system O&M is required. Cost of System Operations/O&M : There are no active remediation systems at OU11, therefore no system O&M is required. Early Indications of Potential Remedy Failure: None. Implementation of Institutional Controls and Other Measures: LUCs have been implemented as evidenced by the NAS Pensacola Master Plan dated December 2007.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 6-18 CTO 0030 6.7.2 Question B: Are the exposure assumptions, toxicity data, cleanup levels, and RAOs used at the time of the remedy selection still valid? Exposure Assumptions: There have been no changes in the physical conditions of the site that would affect the protectiveness of the remedy. Changes to Standards and To Be Considered: ARARs and TBCs considered during preparation of the ROD were reviewed to determine changes to standards since the remedy was implemented. For soil, there are no changes to the cleanup goals identified in the ROD. For groundwater, there are two COCs that currently have less stringent cleanup criteria compared to the ROD (phenanthrene and copper), and there is one COC (cadmium) that currently has a slig htly more stringent criter ion compared to the ROD. The LTM Plan was prepared according to the action-specific ARAR for LTM Plans. Changes in Exposure Pathways: No changes in the site conditions or land use that affect exposure pathways were identified as part of the Five-Year Review. Exposure to the site groundwater is still restricted by the institutional controls. Changes in Toxicity and Other Contaminant Characteristics: There have been no changes in human health or ecological toxicity criteria that would impact protectiveness of the remedy. Changes in Risk Assessment Methodologies: Changes in risk assessment methodologies since the time of the ROD do not call into questi on the protectiveness of the remedy. 6.7.3 Question C: Has any other information come to light that could call into question the protectiveness of the remedy? No additional information has come to light that calls into question the protectiveness of the remedy. 6.8 ISSUES Issues were discovered during the Five-Year Review and are noted in Table 6-7.

FDEP concurred with the ROD on September 30, 2006. Implementation of the reme dial actions at OU13 began in 2007. This Five-Year Review consisted of historic and current data collec ted over a five-year period and provides a status update for OU13 Sites 8 (Rifle Range Disposal Area) and 24 (DDT Mixing Area). This Five-Year Review for OU13 is being conduct ed because hazardous substances, pollutants, or contaminants remain at the site above levels that a llow for unlimited use and unrestricted exposure. 7.1 SITE CHRONOLOGY A list of important OU13 historical events and relevant dates in the site chronology is shown in Table 7-1.

Tower Road and are locat ed southeast of the intersection of John H. Tower and Taylor Roads at NAS Pensacola (Figure 7-1). The site is located in an industrialized portion of NAS Pensacola. Site 8 Site 8, shown in Figure 7-1, is an approximate 450by 600-foot area currently occupied by Building 3561, which houses the NAS Pensacola PWC Maintenance /Material Department. An extensive asphalt-paved area surrounds Building 3561 to the north, east, and west, covering nearly all land surface. The PWC stores building materials on the paved area west of the building. Various solid wastes and dry refuse were reportedly placed in trenches and burned at Site 8 during the late 1950s and early 1960s. Aerial photographs and maps from the 1950s and 1960s show a rifle range at Building 3561s current location. Earlier aerial ph otographs show an excavation at the northern end of the rifle range, and later photographs show the excavated area as overgr own with vegetation. Most of the excavation area observed in earlier photographs is currently covered by Building 3561 and surrounding paved area, which were constructed during the mid-197 0s. Facility personnel reported waste or residue

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 7-3 CTO 0030 were not identified during the buildings construc tion (NEESA, 1983). However, cemetery personnel have reported finding buried metal, rubber, and plastic aircraft parts during excavation along Site 24s eastern boundary (Tetra Tech, 2006b). Building 3561 was constructed in the mid-1970s and is first visible in aerial photographs from April 1976. During most of the 1980s, a limited portion of Building 3561 was used as a pesticide storage and equipment rinsing area. A tank wash rack rinsing area was constructed in March 1981 midway along Building 3561s eastern side to contain and collect pesticide equipment wash water and rinsate. Wastewater from the wash rack was discharged to the sanitary sewer system. Base pest control operations were moved from Building 3561 to their current location at Building 1538 in the early 1990s (NEESA, 1983; Tetra Tech, 2006b). Other buildings within the Site 8 area include: Building 3680, Hazardous Material Storage Building Building 3817, Gas Bottle Storage Shed Building 3834, Material Storage Building 3816, Lumber Storage Shed Site 24 Site 24, shown in Figure 7-1, is immediately nort h of Building 3561, near the northwest corner of the Barrancas National Cemetery. The central and nort hern portions of Site 24 are primarily unpaved and sparsely covered with native grasses and trees. However, the fenced storage area around Building 3678, in Site 24s southern portion, has a gravel/crushed shell land surface. An unimproved dirt road runs west to east across the sites center. From the early 1950s until the early 1960s, Site 24 wa s used to mix DDT with diesel fuel for mosquito control. Reportedly, DDT was spilled in the mixing area duri ng transfer from drum s to spray tanks, and may have contaminated local soil and groundwater. DDT was aerially applied for at least 10 years to control mosquito outbreaks. In later years, DDT was ap plied by a fogger machine. It is estimated that up to 20 gallons of diesel/DDT solution may have been spilled during the years of operation at the site (NEESA, 1983). The fenced storage area north of Building 3561 was developed during the mid-1980s and the PWC storage building was constructed inside the fenced area prior to November 1989. A water supply well (NAS Pensacola Well No. 1) that is no longer used is located upgradient of the combined site area, approximately 0.3 miles to the sout heast; potable water is currently obt ained from NTTC Corry Station. The NAS Pensacola Well No. 1 is screened in t he main producing zone beneath the low permeability zone, which separates it from the surficial aquifer.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 7-4 CTO 0030 7.2.2 Land and Resource Use Site 8 Site 8 is generally flat with a land surface elevation averaging 29 feet above mean sea level. Miscellaneous office trailers and fenced storage, including Building 3561, are within the Site 8 boundaries. The paved area east of Building 3561 is used for PWC storage and employee parking. Sidewalks and a grassy median are to the south, between Buildings 3560 and 3561. Although it is not completely shown on the figure, most of Site 8 is su rrounded by chain-link fencing. Site use is projected to remain consistent with current use. At Site 8, the depth-to-water measurements ranged from approximately 8 feet bls across most of the site to approximately 11 feet bls in the northeastern portion of the site. Site 24 Site 24 is generally flat with land surface elevations approximately 24 to 26 feet above mean sea level. Surface drainage across the site is precluded by t he high permeability of the surficial soil which allows direct, rapid infiltration of precipitation. The Barranc as National Cemetery currently occupies most of the Site; however, Building 3678 is located on the s outhern end of the site boundary. Depth-to-water measurements at Site 24 ranged from approximately 5.5 feet bls in the western portion to approximately 8.5 feet bls in the southern portion. Overall, th is flow regime generally mimics the local topography, sloping slightly north-northeast across the area. Groundwater is not currently used as a potable water source at OU13, (Tetra Tech, 2006b). The main sour ce of potable water for NAS Pensacola is the Navyowned well field located at NTTC Corry Station, whic h is located approximately three miles north of NAS Pensacola on the northern (opposite) side of Bayou Grande. The projected future site use continues to be a cemetery (Tetra Tech, 2006b). 7.3 HISTORY OF CONTAMINATION Site 8 Analytical data generated by investigations of site soils revealed the presence of cadmium, lead, TRPH, PAH, fluometuron (carbamate, a pesticide), and dieldr in in the soil at OU13, Site 8. The detected concentrations of cadmium and dieldrin exceeded thei r applicable federal and state screening criteria for residential exposure and leachability to groun dwater in effect at that time.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 7-6 CTO 0030 The groundwater investigation indicated that only cadmium, manganese, and an isolated lead detection exceeded federal and state CTLs and NAS Pensac ola background concentrations in groundwater samples collected from Site 8. Antimony exceeded its federal and state CTLs in two groundwater samples; however, there is no NAS Pensacola bac kground concentration for antimony. With the exception of one antimony detection, al l exceedances were from monitoring wells located at the north and northeastern portion of the site. This distribution is consistent with past disposal of metallic-alloy aircraft refuse or other metallic material that may lie beneath Building 3561s current location and the sites northern shallow groundwater flow. The extent of shallow groundwater impact does not extend to the farthest down-gradient well at Site 8, as confirme d by no inorganic exceedances of federal and state CTLs in the Phase II groundwater sample from that location. None of the targeted VOCs, SVOCs, or PCBs were detected at concentrations that exceed t heir federal or state CTLs in the Site 8 groundwater. Site 24 Carcinogenic PAHs, pesticides and inorganics were detected in soil samples collected at Site 24. The concentrations of inorganic soil contaminants are sim ilar to background or are attributed to application of fertilizer in the immediate area of sample collection. The human health risk assessment conducted during the RI for Site 24 indicates that benzo(a)pyrene equivalent concentration (BEQs) for carcinogenic PAHs (cPAHs), arsenic, chlordane, dieldrin, and heptachlor epoxide each contribute to the estimated risk for one or more of the soil exposure pathways evaluated for Site 24. The cPAHs were attributed to the adjacent road and vehicular traffic because small pieces of asphalt were observed in the surface soil sa mples. Pesticides and arsenic were attributable to routine application in accordance with regulations and are not site-related. These constituents were detected in soils at a small area (approximately 0. 5 acre) along John H. Tower Road on the western boundary of the site. The cPAHs BEQ was the principal contributor to the ILCR projected for the combined soil pathway and arsenic, chlordane, dieldrin, and heptachlor epoxid e were secondary contributors. Arsenic and PAHs were the only carcinogenic COCs identified relative to future site workers, with a projected combined ILCR. A soil pathway-related was not i dentified for cPAHs, arsenic, chlo rdane, dieldrin, and heptachlor epoxide under the current maintenance worker scena rio. When the BEQ concentration for the cPAHs was considered to not contribute to the ILCR, no unac ceptable risk were considered to be present for the current and future receptors evaluated for Site 24. Therefore, as indicated in the ROD no further CERCLA action was deemed necessary.

PAGE 130

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 7-7 CTO 0030 Concentrations of iron and manganese that have been detected in groundwater samples from the shallow aquifer zone at Site 24 are attributed to fertilizer a pplication, which commonly contains water-soluble forms of these inorganics as essential nutrien ts. Iron and manganese have been detected at concentrations exceeding their federal and state CTLs. Metal fragments were found in the subsurface soil north of Building 3678, indicating that Site 8 fill activities extended to, or have been reworked onto Site 24. Based on this evidence, the concentrations of antimony, cadmium, nickel, and thallium exceedances det ected in groundwater samples from the shallow aquifer zone are attributed to metal-alloy debris disp osal at Site 8 and/or Site 24. Antimony, cadmium, nickel, and thallium have sporadically exceeded their federal and state CTLs. In the RI Addendum investigation, concentrations of aluminum, calcium, iron, magnesium, and sodium concentrations have also exceeded federal and state CTLs and NAS Pens acola background concentrations. Relatively low concentrations of methylene chloride, trichloroet hene, and vinyl chloride have also been detected at concentrations that slightly ex ceeded their federal and state CTLs. The source of these inorganics and organic compounds is suspected to be from past disposal activities at Site 8 and/or Site 24. Pesticides have not been detected in the six down-gradient m onitoring wells installed for the RI Addendum investigation. SVOCs and PCBs have not been detected at concentrations above their federal and state CTLs. 7.3.1 Initial Response As a result of the hazard pres ented by potential exposure to the i dentified contaminants, CH2M Hill conducted IRAs at OU13 from June 28, 2004 to August 25, 2005. The objective of the IRA was to remove soil from Site 8 that was contaminated by COCs at concentrations that exceed residential exposure and leachability to groundwater criteria. Delineation samp les were collected and the remedial volume was calculated for the protection of human health and leachability to groundwater SCTLs. Approximately 634 cubic yards of cadmium impacted soil and approxim ately 429 cubic yards of dieldrin contaminated soil was removed from Site 8. The removal action is described in the IRA Report, Excavation of Contaminated Soil at Operable Unit 13 Site 8 (CH2 M Hill, 2004). The backfill material was analyzed for USEPA Contract Laboratory Program Ta rget Compound List an d Target Analyte List, and determined to be clean fill. 7.3.2 Basis for Taking Action A baseline risk assessment was conducted for OU13 dur ing the RI to assess the COCs (inorganic and organic constituents) and the potential for unac ceptable risk to human health and environment with regard to specific land use scenarios. Based on unacceptable risk posed by the COCs, a response action was selected in the ROD to protect the public health, welfare, and the environment from actual or

PAGE 131

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 7-8 CTO 0030 threatened releases of the COCs into the environm ent. Although the baseline risk assessment presented unacceptable risks for both soil and groundwater at Site 8, an IRA for soil was completed in October 2004 to eliminate the unacceptable risks to human health and leachability of the CO Cs to groundwater. No unacceptable risk for the COCs in soil at Site 24 were considered to be present for the current and future receptors. The COCs that were identified in the OU 13 RI and prior to the IRA for soil at Sites 8 and 24 are included in Table 7-2. The extent of impacted media driving the unacceptable excess risk to groundwater at Sites 8 and 24 is limited. The magnitude of this contamination is low relative to most ARARs. This unacceptable excess risk to human health should be qualified based on fact ors that affect the exposure potential by humans to impacted media at Sites 8 and 24. The shallow groundwa ter of the surficial zone at both sites is not currently used as a groundwater source due to its poor ambient quality. The main source of potable water for NAS Pensacola is the Navy-owned well field loca ted at NTTC Corry Station, which is located approximately 3 miles north of NAS Pensacola on the northern (opposite) side of Bayou Grande. These two factors greatly reduce the actual exposure potenti al to groundwater at Sites 8 and 24. However, because the state of Florida considers all groundwater to be potable, the basis for taking action at OU13 is the presence of COCs in groundwater at concentr ations that exceed federal and state drinking water standards. The COCs identified for groundwater at Sites 8 and 24 are included in Table 7-2. The concentrations of COCs detected in soil sample s collected at Site 24 were not within the USEPA acceptable risk range (1x10-4 to 1x10-6) and the FDEP target risk criteria (1x10-6) for current workers, trespassers, and future residents (Tetra Tech, 2006b). Concentrations of contaminants in groundwater were compared against the Florida natural attenuation default source concentrations in Table V of Chapter 62-777 F.A.C. to evaluate the use of natural attenuation as a remedy for groun dwater. Contaminants that exceede d the Florida natural attenuation default source concentration criteria were listed as COCs.

RAOs were developed only for groundwater based on the data collected during the RI and IRA to aid in the development and screening of remedial alternatives to be considered for the RO D. The goals of the remedies selected for soil and groundwater at OU13 are to protect human health and the environment by eliminating, reducing, or controlling hazards posed by the site and to meet ARARs. Based upon consideration of the requirements of CERC LA, the NCP, the detailed analysis of alternatives and public and state comments, the Navy selected No Action for soil at OU13, as an IRA had been conducted for Site 8 and no unacceptable risk were considered to be present for the current and future receptors evaluated for Site 24.. Results of the IRA, which were available at the time of ROD development, indicate that no site-related contaminat ion above Florida residential direct exposure and leachability to groundwater SCTLs remained on site. The Navy selected LUCs with groundwater monitoring to address contamination of groundwater by the COCs at OU13. Both alternatives, once implemented, will be protective of human health and the environment, are cost-effective, and result in permanent solutions to the maximum extent practicabl e. With the implementation of these alternatives, the site will be protective of human health and the en vironment. Table 7-3 lists the RAOs for developed in the ROD for groundwater at OU13.

The remedy was selected for the following reasons: Because the IRA was performed, soil at Site 8 poses no risk. No unacceptable risks were considered to be present for the current and future receptors evaluated for Site 24. The OU13 area is currently used for industrial uses including a paved area for PWC storage and employee parking (Site 8) and buffer zone and cemetery burials in Barrancas National Cemetery (Site 24). The projected future site use is consistent with the current uses. Groundwater on site currently exceeds remedial goals. However, natural degradation appears to be occurring and there is no evidence of contaminant migration off-site. Furthe rmore, the surficial aquifer is not likely to be used for potable water due to its low quality. Source control remediation will address restricting exposure to contaminated groundwater. Source control shall include LUCs which will be used to restrict groundwater use of the surficial zone of the sand and gravel aquifer on site. A Remedial Design for Land Use Controls and Groundwater Monitoring at OU13 (Tetra Tech, 2008a) was prepared as the land use component of the Remedial Design. In accordance with the Site Management Plan and the NAS Pensacola FFA, the LUC RD contains LUC implementation and maintenance ac tions, and periodic inspections by the USEPA and FDEP. The Navy is responsible for implementing, maintaining, reporting on, and enforcing the LUCs. Although the Navy may later transfer these procedur al responsibilities to another party by contract,

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 7-11 CTO 0030 property transfer agreement, or throu gh other means, the Navy shall retain ultimate responsibility for the remedial integrity. The following components constitute the remedial action for OU13 to address the groundwater RAO: Performing groundwater monitoring to ensure the COCs are not moving off-site. Conducting reviews to determine whether groun dwater performance standards continue to be appropriate. Implementing institutional controls to restrict use of groundwater from the surficial zone of the sand and gravel aquifer within 300 feet of the site. Reviewing the institutional controls and certificati on in order to determine if they should remain in place or be modified to reflect changing site conditions. 7.4.2 Remedy Implementation at OU13 The OU13 ROD specified removal of isolated hot spot areas of soil impacted by the COCs to reduce the potential for direct exposure. Approximately 634 cubic yards of dieldrin-impacted soil were removed from the eastern side of Building 3561 and approximately 429 cubic yards of cadmium-impacted soil were also removed from the western side of Building 3561. All soil with dieldrin and cadmium at concentrations exceeding their respective remedial goals of 0.004 mg/kg, and 0.005 g/L, respectively were removed. The Groundwater Monitoring Plan has been approved and groundwater monitoring has been initiated. Total remediation cost expended to date for this project is $83,996. 7.4.3 System O&M at OU13 The costs for the selected re medy does not included O&M. 7.4.4 Long-Term Groundwater Monitoring at OU13 In November 2007, the Navy began long-term groundwat er monitoring for OU13. Semiannual sampling events were conducted in November 2007, May 2008, October 2008, May 2009, June 2009, April 2010, July 2010, March 2011, October 2011, and January 2012. As stated in the ROD for OU13 (Tetra Tech, 2006b), the Navys original 2006 cost estimate for implementation of remedial action and closure of OU13 and 30 years of LTM program (risk-reduction) was $610,200. The approximate cost to date for remedi al actions including O&M and monitoring at OU13 is $83, 996.

No issues were identified during the Five-Year Review process and the remedy was found to be protective. 7.5.1 Protectiveness Statements from the Last Review Based on the results of the 2008 Five-Year Review, the remedy was expected to be protective of human health and the environment upon attainment of groundwater cleanup goals, through natural attenuation. 7.5.2 Status of Recommendations and Follow-up Actions from Last Review No recommendations or follow up actions were identified during the previous Five-Year Review. 7.6 FIVE-YEAR REVIEW PROCESS This is the second Five-Year Review for this site. Members of the NAS Pensacola Partnering Team were notified of the initiation of the Five-Year Review in January 2012. The Five-Year Review was led by Gerald Walker of Tetra Tech, the NAVFAC SE Navy CLEAN Contractor, and included other Tetra Tech staff. Patty Marajh-Whittemore of NAVFAC SE, Greg Campbell of NAS Pensacola Public Works Department, Tim Woolheater of U SEPA, David Grabka of FDEP, and Sam Naik of CH2M Hill assisted in the review. The review included the following components: Document Review Data Review Site Inspection Five-Year Review Report development and review 7.6.1 Document Review This Five-Year Review consisted of a review of rele vant documents including the ROD, IRA Report, Draft LUC RD, Natural Attenuation Monitoring Report s and applicable federal and state statutes.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 7-13 CTO 0030 7.6.2 Data Review 7.6.2.1 Review of COC Data for Groundwater Since the initial ROD was signed, five years of semiannual monitoring and sampling have occurred. The COCs for groundwater established for OU13 in the RO D are: antimony, cadmium, dieldrin, heptachlor epoxide, iron, lead, manganese, methylene chloride nickel, thallium, trichloroethene, and vinyl chloride. Antimony, cadmium and manganese have exceeded t heir respective Florida CTLs in groundwater samples collected during every sampling event since t he inception of the groundwater monitoring. One lead exceedance was detected during the November /December 2007 sampling event at a single one monitoring well, PEN-43-13S. The groundwater at OU13 was evaluated in light of the changes in the number of monitoring well locations with contaminants that exceed CTLs, a nd the changes in contaminant concentrations in individual monitoring wells with time. The trend analys is for the COCs for groundwater at NAS Pensacola was performed using the Mann-Kendall test (ProUC L Version 4.1.00 [Lockheed Martin Environmental Services, 2010]) at a 95 percent confidence level a nd groundwater sample data collected from 2007 to 2011 (Appendix G). The Mann-Kendall test is used because it does not assume any particular distributional form and accommodates values below the detection limit by assigning them a common value ( the detection limit). During the November and December 2007 groundwater sampling events, 12 monitoring wells were sampled and the groundwater was analyzed for the 12 groundwater COCs. Only three of the COCs, cadmium, iron, and manganese, were detected in the groundwater samples at concentrations that exceeded their respective Florida CTLs. VOCs an d pesticides were not detected in the 2007 sampling event. During the April and October 2008 groundwater sampling events, 11 monitoring wells (monitoring well 24GS10R was not sampled in April 2008 due to an obstruction in the well) were sampled and the groundwater was analyzed for the 12groundwater COCs. Only four of the COCs antimony, cadmium, iron, and manganese were detected in the groundwater samples at co ncentrations that exceeded their Florida CTLs. VOCs were detected but were at concentrations below their Florida cleanup target levels (CTLs). Pesticides were not detected in the 2008 sampling event. During the March and October 2009 groundwater sa mpling events, 12 monitoring wells were sampled and the groundwater was analyzed for the 12 groundwater COCs. Only three of the COCs, cadmium,

PAGE 137

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 7-14 CTO 0030 iron, and manganese, were detected in the groundwater samples at concentrations that exceeded their respective Florida CTLs. VOCs and pesticides were not detected in the 2009 sampling event. During the March and October 2010 groundwater sa mpling events, 12 monitoring wells were sampled and the groundwater was analyzed for the 12 groundwat er COCs. Only four of the COCs, antimony, cadmium, iron, and manganese, were detected in groun dwater samples at concentrations that exceeded their respective Florida CTLs. Bromodichloromethane, although not a COC, was the only VOC that exceeded its CTL. If the criterion for total trihalomet hanes is applied per Florida Chapter 62-550, F.A.C., the detected concentration does not exceed its MCL. Pesticides were not detected in the 2010 sampling event. During the October 2011 groundwater sampling even t, 11 monitoring wells (24GS02R was not sampled due to an obstruction) were sampled and the groundwater was analyzed for the 12 groundwater COCs. Only three of the COCs, cadmium, iron, and manga nese were detected in the groundwater samples at concentrations that exceeded their respective Florida CTLs. VOCs and pesticides were not detected in the 2009 sampling event. The data collected during the 2007, 2008, 2009, 2010, and 2011 groundwater sampling events were evaluated to identify observable trends. Trend analysis results are provided in Appendix G. For metals, in general, cadmium demonstrated no or increasing trends, antimony and iron demonstrated no or decreasing trends, and lead and manganese demonst rated no trends. VOCs, in general, had sporadic detections and no trends were observed. With the exception of a spurious detection of bromodichloromethane at a concentration that excee ded its Florida CTL, VOCs have not exceeded their respective Florida CTLs in the past five years of monitoring. Pesticides have not been detected in the past five years of monitoring. Based on the groundwater flow direction at Site OU13 the sentinel wells at the site are 24GS10, 24GS11 and 24GS15. Historically, iron is the only COC with concentrations above the background concentration (1,707 g/L) established for NAS Pensacola. Mann-Kendal analysis shows an increasing trend in iron concentrations detected in groundwater sample s collected from monitoring well 24GS10 and a decreasing trend in iron concentration s detected in groundwater sample collected from monitoring wells 24GS11 and 24GS15. Even with the increasing trend for monitoring well 24GS10, iron concentrations detected during the October 2011 sampling event did not exceed the background criteria, indicating that off-site migration is not occurring at concentrations above the background, therefore meeting the RAO for OU13.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 7-15 CTO 0030 7.6.2.2 LUC Inspections LUC inspections were conducted annually at OU13 during the period under review. There were no issues identified during annual inspections. 7.6.3 Site Inspection and Interviews Inspections at the site were conducted on May 3, 2012 by Tetra Tech personnel. The purpose of the inspection was to assess the protectiveness of the re medy, including the presence of fencing to restrict access and condition of monitoring wells. Fencing the site was not warranted at OU13 since surficial soil with contaminant concentrations above the remedial g oal were removed from Site 8 and no unacceptable risk were considered to be present for the current and future receptors evaluated for Site 24., Monitoring wells were accessible and appeared to be in good condition. Therefore, no apparent deficiencies noted during the site inspection. The institutional controls that are in place include the restriction of groundwater use of the surficial zone of the sand and gravel aquifer underlying the sites. At the time of the inspection, institutional controls were found to be adequate, and use of groundwater was not observed. Roadways within OU13 appeared adequate, and there were no apparent signs of vandalism or trespassing. An interview was conducted with Greg Campbell, Environmental Engineer for NAS Pensacola, on May 2, 2012. According to the interview, Mr. Campbell indicated he is well informed about the sites activities and progress, and was not aware of any comm unity concerns regarding the site or its operation, or of any incidents such as vandalism, trespassing or emergency responses at the site. The interview forms are presented in Appendix H. Mr. Campbell indicated annual LUC inspections are performed. In addition, complaints, violations, or other incidents related to the site requiring a respon se by his office have not occurred. Mr. Campbell indicated closure of the iron re covery system is appropriate. 7.6.4 ARAR Level Changes The following standards were identified as chemical-spec ific ARARs in the ROD. They were reviewed for changes that could affect protectiveness: Safe Drinking Water Act MCLs (40 CFR 141.111.16) Safe Drinking Water Act MCLs (40 CFR 141.501.51) Florida Drinking Water Standards, Monitori ng and Reporting, Chapter 62-550, F.A.C.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 7-16 CTO 0030 Florida Cleanup Target Levels, Chapter 62-777, F.A.C. Contaminated Site Cleanup Criteria, Chapter 62-780, F.A.C. Ground Water Classes, Standards, and Exemptions, Chapter 62-520, F.A.C. With the exception of Chapter 62-777, F.A.C., ther e have been no changes in the MCLs, MCLGs, Florida Drinking Water Standards, Florida Ground Water Classes, Florida GCTLs, and Florida Site cleanup requirements that affect the protectiveness of the remedy. There are no location-specific or action-specific ARARs identified in the ROD. The cadmium and dieldrin contaminated areas were re moved from Site 8 in 2004. The cleanup criteria used in Site 8 IRA for cadmium and dieldrin were based on their Florida SCTLs that were in effect prior to the revision of Chapter 62-777, F.A.C. in 2005. In the 2005 revision, the Florida industrial direct exposure SCTL for cadmium increased from 1,300 to 1,700 mg/kg, and the leachability to Groundwater SCTL decreased from 8 to 7.5 mg/kg. The Florida industrial direct exposure SCTL for dieldrin remained the same at 0.3 mg/kg, but the leachability to ground water SCTL decreased from 0.004 to 0.002 mg/kg. Because the Florida industrial direct exposure SCTL criterion for cadmium increased and Florida industrial direct exposure SCTL for dieldrin criterion remained the same, the remedy remains protective in the shortand long-term for both COCs. However, the Florida leachability to groundwater SCTLs for cadmium and dieldrin have decreased, so there may be slightly less protectiveness. Also, it should be noted that dieldrin has not been detected in a groundwater sample since 2007 (monitoring well 08GR01R); therefore, the change in the leachability to groundwater SCTL for dieldrin may be inconsequential. 7.7 TECHNICAL ASSESSMENT 7.7.1 Question A: Is the remedy functioning as intended by the ROD? The review of documents, ARARs, risk assumptions, and the results of the site inspection indicates that the remedy is functioning as intended by the ROD. Health and Safety Plan/Work Plan : A Site specific Health and Sa fety Plan (HASP) and Groundwater Monitoring Work Plan has been developed. Remedial Action Performance: Contaminated soil was removed from Site 8 and replaced with clean backfill. The Groundwater Monitoring Plan for OU 13 has been approved and natural attenuation monitoring has been initiated.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 7-17 CTO 0030 System O&M : There are no active remediation systems at OU13 and therefore no system O&M is required. Cost of System Operations/O&M : There are no active remediation systems at OU13 and therefore no system O&M is required. Opportunities for Optimization : Optimization of the groundwater monitoring effort was completed. Early Indications of Potential Remedy Failure. No indicators of potential remedy failure have been identified. Implementation of Institutional Controls and Other Measures: The Remedial Design outlining the site specific LUCIP has been completed and complies with the LUCAP agreement between the Navy, USEPA, and FDEP. OU13, Sites 8 and 24 will be available for industrial use, but residential use of the site would be prohibited. The Navy will be required to conduct periodic site inspections and ensure that the proposed LUCs are being properly maintained and adm inistered. Groundwater use of the surficial zone of the sand and gravel aquifer in the immediate vicinity of OU13 is prohibited. The Navy will conduct an annual review of the institutional co ntrols and certify that the controls should either remain in place or be modified to reflect changing site conditions. 7.7.2 Question B: Are the exposure assumptions, toxicity data, cleanup levels, and RAOs used at the time of the remedy selection still valid? Exposure Assumptions: There have been no changes in the physical conditions of the site that would affect the protectiveness of the remedy. Changes to Standards and To Be Considered: ARARs and TBCs considered during preparation of the ROD were reviewed to determine changes to stan dards since the remedy was implemented. The industrial direct exposure SCTL for cadmium increa sed from 1,300 to 1,700 mg/kg, and the leachability to Groundwater SCTL criteria decreased from 8 to 7.5 mg/kg. The leachability to groundwater SCTL for dieldrin decreased from 0.004 to 0.002 mg/kg. For groundwater, there have been no changes that affect the protectiveness. Changes in Exposure Pathways: No changes in the site conditions or land use that affect exposure pathways were identified as part of the Five-Year Review. Exposure to the site groundwater is still restricted by institutional controls.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 7-18 CTO 0030 Changes in Toxicity and Other Contaminant Characteristics: There have been no changes in human health or ecological toxicity criteria that would impact protectiveness of the remedy. Changes in Risk Assessment Methodologies: Changes in risk assessment methodologies since the time of the ROD do not call into questi on the protectiveness of the remedy. 7.7.3 Question C: Has any other information come to light that could call into question the protectiveness of the remedy? No additional information has come to light that calls into question the protectiveness of the remedy. 7.8 ISSUES No issues regarding OU13 were discovered during the Five-Year Review. 7.9 RECOMMENDATIONS AND FOLLOW-UP ACTIONS It is recommended that natural attenuation monitoring continue at OU13. 7.10 PROTECTIVENESS STATEMENT The remedy at OU13 upon completion is expected to be protective of human health and the environment, and in the interim, exposure pathway s that could result in unacceptable risks are being controlled.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 8-1 CTO 0030 8.0 OPERABLE UNIT 18 The OU18 ROD was issued by the Navy and the USEPA on April 12, 2010. FDEP concurred with the ROD on June 2, 2010. Implementation of remedial ac tion at Site 43 began in 2012. This five-year review consists of data collected since the ROD was si gned and provides a status update for Site 43 Demolition Debris Disposal Area. This statutory review for Site 43 is being conducted because hazardous substances, pollutants, or contaminants rema in at the site above levels that allow for unlimited use and unrestricted exposure. 8.1 SITE CHRONOLOGY A list of significant Site 43 historical events and relevant dates is provided in Table 8-1.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 8-2 CTO 0030 8.2 BACKGROUND 8.2.1 Physical Characteristics of Site 43 OU18, also referred to as Site 43, encompass es approximately 180,000 squar e feet (4.1 acres), approximately 40,000 of which are covered by a paved parking lot (see Figure 8-1). The remainder of the site is an open grassy area covered with scattered trees. Site 43 is located in a developed area in the eastern portion of NAS Pensacola, at the southwestern corner of Murray and Taylor Roads and north of BOQ Road, which provides access to the Officers Quarte rs. The site is on the eastern slope of a shallow closed depression, bound by paved roads on all four sides. Surface water features are not present at the site, and overland runoff flows west into the depressi on. A designated wetland and drainage ditch located approximately 500 feet east of the site are the nearest surface water bodies. Soil at Site 43 consists of fine to coarse excessiv ely drained sands formed in sandy marine environments and characterized by rapid infiltration and slow runoff. Soils encountered at Site 43 during the RI were typical of regional undifferentiated Pleistocene marine deposits made up of light brown to tan fine quartz sand with associated stringers and lenses of gravel and clay. From the ground surface to 4 feet bls, many areas of the site showed signs of disturbance eith er from waste disposal or 2001 IRA excavation activities. Below 4 feet, typical lithologies included m edium to fine silty or clayey sand ranging from light gray or tan to dark brown in color. Significant clay or gravel horizons were not encountered. Depths to groundwater ranged from approximately 12 to 16 feet bls during the RI, and groundwater flow was generally to the east. 8.2.2 Land and Resource Use at Site 43 The site previously contained a tennis court and building foundation/basketball court; however, the tennis and basketball courts were removed in 2003. Prior to the most recent use as a recreational area, site use is unknown. Recreational users and maintenance workers use the si te currently and are expect ed to continue use into the foreseeable future. On-site wildlife may temporarily use Site 43, but due to lack of suitable cover, wildlife use is assumed to be infrequent. The NAS Pensacola Base Master Plan identifies the planned future use of the site as open space, indicating no future development or construction activities are planned for the site. If future land use at Site 43 differs from the reasonably anticipated land use, the Navy will reassess risks approp riate to the future use.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 8-4 CTO 0030 The nearest water supply well to Site 43 is located approximately 1,600 feet west -southwest; however it is no longer used. The main source of potable water for NAS Pensacola is the Navy-owned well field located at NTTC Corry Station, which is located app roximately three miles north of NAS Pensacola on the northern (opposite) side of Bayou Grande. 8.3 HISTORY OF CONTAMINATION Environmental investigations at Site 43 began in December 1992 when a child using a metal detector discovered a partially exposed drum east of the tennis court, and subsequent site reconnaissance identified additional drums and smaller rusted metallic debris in the area. Odors, visible soil stains, or other indications of contaminant release were not observed. The area surrounding the drums was fenced to prevent general access until further investigations could be conducted. The precise locations of the debris disposal areas were unknown; however, approx imate locations of several disposal areas were determined based on the results of subsequent investigations. 8.3.1 Initial Responses at Site 43 A Geophysical Investigation was conducted in 1994 to assess the size of the disposal area and number of drums buried in the area. A total of 25 geophysical anomalies were identified during the investigation, but the actual number of drums disposed in the area was not determined. After the Geophysical Investigation, it was recommended that the drum disposal area and several anomalies outside of the disposal area be further investigated thro ugh the use of test pits or trenches. Site characterization sampling was conducted in 1999 and included surface and subsurface soil sampling from anomalous locations identified through the use of test pits and groundwater sampling from temporary micro wells. Drums with sufficient conten ts were sampled and were found to contain PAHs at concentrations exceeding Florida residential direct exposure SCTLs and metals at concentrations exceeding residential and industrial direct exposure SCTLs. Concentrations of benzo(a)pyrene, antimony, arsenic, barium, copper, iron, and vanadium exceeded Florida residential direct exposure SCTLs. Concentrations of arsenic and lead exceeded Florida residential direct exposure SCTLs. Fourteen drums were removed during the course of the investigation. Samples of surface soil, subsurface soil (beneath t he drum disposal depth), and soil just above the water table were collected during this investigation. Concentrations of benzo(a)pyrene, antimony, arsenic, barium, copper, iron, zinc, lead, nickel, and vanadium in surface and shallow subsurface soil samples exceeded Florida residential direct exposure SCTLs. Leachability to groundwater SCTLs were exceeded in the surface soil samples by antimony and nickel. Leachability to groundwater SCTLs were exceeded in the subsurface soil samples by antimony, arsenic, barium, nickel, and zinc.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 8-5 CTO 0030 Groundwater samples contained iron and aluminum at concentrations that exceeded their federal and state CTLs. An IRA to remove metal debris and contaminated surface and subsurface soil was recommended. The IRA was conducted in 2001 and included removal of 657 cubic yards of soil and debris including 20 to 25 rusted metal drums and drum parts and inert ornamental ordnance and munitions. Prior to the IRA, remedial goals were developed for some COCs using 95 percent upper confidence limits (UCLs) for surface soil. COC concentrations in surface and s ubsurface soil samples collected prior to excavation were compared to these remedial goals to determine the extent of contamination requiring removal. Remedial goals were re-evaluated and revised after excavation activities were completed, and it was determined that additional areas of contaminated soil required excavation. Based on this information, the IRA Report recommended an RI and FS. 8.3.2 Basis for Taking Action at Site 43 Arsenic, barium, copper, vanadium, and cPAHs were detected in surface and subsurface soil at concentrations exceeding Floridas residential risk-b ased criteria, and cPAHs and lead were detected at concentrations exceeding Floridas industrial risk-based screening criteria and site-specific recreational criteria. Unacceptable risks were identified for resi dential and non-residential exposure to lead in soil and groundwater at Site 43. Because risks were identified under the current and reasonably anticipated future land use scenario (non-residential), it was de termined that a response action was necessary to protect the public health or welfare or the environment from actual or threatened releases of hazardous substances, pollutants, or contaminants into the environment that may present an imminent and substantial endangerment to public health or welfare. COCs related to each medium are summarized in Table 8-2.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 8-6 CTO 0030 8.4 REMEDIAL ACTIONS 8.4.1 Remedy Selection at Site 43 The ROD for NAS Pensacola Site 43 was finalized on Ap ril 12, 2010. RAOs were developed as a result of data collected during the RI to aid in the development and screening of remedial alternatives to be considered for the ROD. The goals of the selected soil and groundwater remedies at Site 43 are to protect human health and the environment by eliminating, reducing, or controllin g hazards posed by the site and to meet ARARs. Based on consideration of the requirements of CERC LA, the NCP, the detailed analysis of alternatives, and any comments received from USEPA, FDEP, and the p ublic, excavation and off-site disposal of the most contaminated soil (in unpaved areas) to meet Florida industrial direct exposure SCTLs; groundwater monitoring; and LUCs to prohibit future residential use, to ensure maintenance of paved areas, and prohibit groundwater use were selected to address contam ination at Site 43. Table 8-3 lists the RAOs for Site 43. TABLE 8-3 OU18 REMEDIAL ACTION OBJECTIVES FIVE-YEAR REVIEW NAVAL AIR STATION PENSACOLA PENSACOLA, FLORIDA Medium COCs Remedial Action Objectives Soil Arsenic, Barium, Copper, Lead, Vanadium, and cPAHs. Prevent unacceptable human health risk associated with exposure to soil containing concentrations greater than Floridas industrial direct exposure SCTLs. Groundwater Lead Prevent unacceptable human health risk associated with exposure to groundwater containing concentrations greater than the Floridas CTL and USEPA Action Level. Four soil remedial alternatives and three groundwater remedial alternatives were evaluated in the OU18 FS to address the two RAOs. The selected remedy for Site 43 included limited soil excavation and off-site disposal to meet industrial SCTLs, LUCs, and long-term groundwater monitoring. These soil and groundwater alternatives were selected because they provide the best balance of tradeoffs with respect to the nine CERCLA remedy evaluation criteria and will allow for continued non-residential use of the property. The following components, as provided in t he Site 43 ROD, constitute the remedial action for Site 43 to address the soil and groundwater RAOs:

PAGE 148

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 8-7 CTO 0030 Excavation and off-site disposal of the most contaminated soil (in unpaved areas) to meet industrial SCTLs. Collection and analysis of groundwater samples fr om four monitoring wells including: one existing well and three new downgradient wells, quarterly for one year. The samples will be analyzed for lead only. After one year, data will be evaluated to determine future monitoring requirements. Additional groundwater samples will be collected in the area surrounding existing monitoring well PEN-43-13S to confirm the extent of the ground water contamination and to provide direction for installation of the new downgradient wells. The ROD also states that: The Selected Remedy in cludes 1 year of groundwater monitoring followed by a re-evaluation of conditions. Any modifications to the LUCs to be implemented for groundwater based on such a reevaluation(s) will be made in accordance with the provisions of the LUC RD for Site 43. LUCs will be implemented within the Site 43 boundaries to: Prohibit residential use of the site, includ ing housing, child-care facilities, schools, playgrounds, conval escent, or nursing care facilities. Prohibit unauthorized excavation and/or removal of soil with contaminant concentrations exceeding Florida residential SCTLs. Prohibit all uses of groundwater from th e surficial aquifer underlying the site. Maintain the integrity of the paved areas. Maintain the integrity of existing or fu ture monitoring or remediation systems. The ROD states that With regard to soil, becaus e metals contamination does not readily attenuate through natural processes, the LUCs to preclude residential use of the site will need to remain in effect for the foreseeable future unless more active remedi al measures are undertaken to allow for future unrestricted site use. The key factors in the selection of this remedy were as follows: The remedy is consistent with the reasonably ant icipated future non-residential use of the site and will allow continued use of the parking ar ea without disturbance of the pavement. The remedy achieves similar protection at a significantly lower cost less than full-scale removal to achieve unrestricted use and unlimited exposure ($390,000 compared to $706,000).

PAGE 149

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 8-8 CTO 0030 Because it is expected that, with the removal of the soil source, lead in groundwater may rapidly decrease to concentrations less than the Florida CTL and USEPA Action Level, and because long-term LUCs will be required to prevent re sidential development and ensure maintenance of pavement, the inclusion of a groundwater use restriction was not additionally burdensome. 8.4.2 Remedy Implementation at Site 43 A revised final LUC RD was finalized with U SEPA and FDEP concurrence in March 2011. The Navy continues to prepare the UFP-SAP and Remedial Action Work Plan and anticipates submittal of the documents in October 2012. 8.5 PROGRESS SINCE THE LAST FIVE-YEAR REVIEW 8.5.1 Protectiveness Statements from the Last Review This is the first Five-Year Review since the approval of the ROD; therefore, no previous protectiveness statement is available. 8.5.2 Status of Recommendations and Follow-up Actions from Last Review This is the first Five-Year Review since the approval of the ROD; therefore, t here are no follow-up actions. 8.6 FIVE-YEAR REVIEW PROCESS This is the first Five-Year Review for this site. Members of the NAS Pensac ola Partnering Team were notified of the initiation of the Five-Year Review in January 2012.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 8-9 CTO 0030 8.6.1 Document Review This five-year review consisted of a review of relevant documents including the ROD and RI, and applicable federal and state statutes 8.6.2 Data Review Source removal and groundwater monitoring are pending submittal and approval of the UFP-SAP and Remedial Action Work Plan. 8.6.3 Site Inspection and Interviews LUC inspections were conducted annually at OU18 during the period under review. The inspections noted no problematic observations. 8.6.4 Site Inspection and Interviews An inspection was conducted at the site on May 2, 2012 by Tetra Tech personnel. The purpose of the inspection was to assess the protectiveness of the remedy. The institutional controls that are in place include the restriction of land use, restriction of all groundwater use, prohibition of excavation of areas with cont aminated soils without prior approval from the NAS Pensacola Environmental Office, maintenance of the paved parking lot, and maintenance of all existing or future monitoring and on-site remedy components. At the time of the inspection, institutional controls appeared to be adequate, and use of groundwater wa s not observed. Roadways within OU18 appeared adequate, and there were no apparent signs of vandalis m or trespassing. Existing monitoring wells were accessible and in good condition. Signage is in place re stricting access to the site as contaminated soils remain in place. No deficiencies were noted during the site inspection. An interview was conducted with Greg Campbell, Environmental Engineer for NAS Pensacola, on May 2, 2012. According to the interview, Mr. Campbell indicated he is well informed about the sites activities and progress, and was not aware of any comm unity concerns regarding the site or its operation, or of any incidents such as vandalism, trespassing or emergency responses at the site. The interview forms are presented in Appendix I. Mr. Campbell indicated annual LUC inspections are performed. In addition, complaints, violations, or other incidents related to the site requiring a response by his office have not occurred.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 8-10 CTO 0030 8.6.5 ARAR Level Changes The following standards were identified as chemical-spec ific ARARs in the ROD. They were reviewed for changes that could affect protectiveness: Lead and Copper Rule Federal Register 26564 Safe Drinking Water Act MCLs (40 CFR 141.111.16) Safe Drinking Water Act MCLs (40 CFR 141.501.51) Florida Drinking Water Standards, Monitori ng and Reporting, Chapter 62-550, F.A.C. Florida Cleanup Target Levels, Chapter 62-777, F.A.C. Ground Water Classes, Standards, and Exemptions, Chapter 62-520, F.A.C. There have been no other changes in the Lead and Copper Rule, Chapter 62-777, F.A.C., and Chapter 62-550, F.A.C. that affect the pr otectiveness of the remedy. The soil cleanup goals in the ROD are the same as those in Chapter 62-777, F.A.C. The 15 g/L Action Level for lead per the Federal Safe Drinking Water Act and Chapter 62-550, F.A.C. has not changed. The following standards were identified as action-specific ARARs in the ROD. They were reviewed for changes that could affect protectiveness: RCRA Regulations, Identification and Listi ng of Hazardous Wastes (40 CFR Part 262.11 and 264.13(a)(1)) RCRA Regulations, Land Disposal Restrictions for Contaminated Soil (40 CFR Part 268.49) Florida Contaminated Site Cl eanup Criteria Ri sk Management Option Level II, Chapter 62780.680(2), F.A.C. Florida Natural Attenuation with Monitoring Regulation, Chapter 62-780.690(8)(a) thru (c), F.A.C. Florida Water Well Permitting and Construction Requirements, Chapter 62-532.500, F.A.C. Florida Hazardous Waste Requirements for Re medial Action, Chapter 62-730.225(3), F.A.C. The soil excavation and monitoring program have not been implemented, so most of these ARARs were not evaluated. The sections covering General Provisions for Water Well Permitting and Construction and Abandonment of Water Wells in 62-532, F.A.C. were repealed October 7, 2010. Monitoring well installation and abandonment are now addressed in the FDEP Monitoring Well Design and Construction Guidance Manual, 2008.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 8-11 CTO 0030 There are no location-specific ARARs identified in the ROD. 8.7 TECHNICAL ASSESSMENT 8.7.1 Question A: Is the remedy functioning as intended by the ROD? The remedy has not yet been fully implemented. The LUC RD was finalized with USEPA and FDEP concurrence in March 2011. Finalization of the Remedial Action Work Plan is anticipated in October 2012. Remedial Action Performance: Once implemented, the remedy is expected to perform as designed. System O&M: There are no active remediation systems at Site 43 and therefore no system O&M is required. Cost of System Operations/O&M: There are no active remediation syst ems at Site 43 and therefore no system O&M is required. Early Indications of Potential Remedy Failure: None. Implementation of Institutional Controls and Other Measures: The LUC RD was finalized with USEPA and FDEP concurrence in March 2011. Based on the site inspection performed on May 2, 2012, institutional controls have been impl emented and are adequate for the site. 8.7.2 Question B: Are the exposure assumptions, toxicity data, cleanup levels, and RAOs used at the time of the remedy selection still valid? Exposure Assumptions: There have been no changes in the physical conditions of the site that would affect the protectiveness of the remedy. Changes to Standards and To Be Considered: ARARs and TBCs considered during preparation of the ROD were reviewed to determine changes to standards since the remedy was implemented. For soil and groundwater, there are no changes to the cleanup goals identified in the ROD. Because the remedy has not been implemented yet, t he action-specific ARARs could not be evaluated. Changes in Exposure Pathways: No changes in the site conditions or land use that affect exposure pathways were identified as part of the five-year review. Exposure to the site groundwater is still restricted by the institutional control. Changes in Toxicity and Other Contaminant Characteristics: There have been no changes in human health or ecological toxicity criteria that would impact protectiveness of the remedy.

Draft Rev. 1 October 2012 TetraTech/TAL-12-083/0390-7.0 8-12 CTO 0030 Changes in Risk Assessment Methodologies: Changes in risk assessment methodologies since the time of the ROD do not call into questi on the protectiveness of the remedy. 8.7.3 Question C: Has any other information come to light that could call into question the protectiveness of the remedy? No additional information has come to light that calls into question the protectiveness of the remedy. 8.8 ISSUES Issues were discovered during the Five-Year Review and are noted in Table 8-4. TABLE 8-4 OU18 ISSUES FIVE-YEAR REVIEW NAVAL AIR STATION PENSACOLA PENSACOLA, FLORIDA Issues Affects Protectiveness (Y/N) Current Future Once the remedy is implemented as intended in the ROD and ROD Amendment, the remedy will be protective for the long term. The remedy is protective in the short term as LUCs are being implemented. N Y 8.9 RECOMMENDATIONS AND FOLLOW-UP ACTIONS Approval of the Remedial Action Work Plan must be completed prior to remedy implementation. 8.10 PROTECTIVENESS STATEMENT The remedy at OU18 upon completion is expected to be protective of human health and the environment, and in the interim, exposure pathw ays that could result in unaccept able risks are being controlled.
