23 (a) General discharge to ground water. A general discharge
24 to ground water includes all activities occurring at or from an
25 installation or facility which generates a discharge to ground
26 water except discharges generated by stormwater facilities,
27 underground storage facilities, and underground facilities for
28 transportation of waste effluents, pollutants or contaminants.
("13 The general discharge criteria shall apply to specific
30 installations within the general discharge category regardless of
31 size and/or effluent volume, except installations treating
1 domestic waste water discharge of 5000 gallon capacity or less.
2 1. Five Year Zone of Protection. The following discharge
3 shall be allowed within the five year zone of protection subject
("4 to meeting the specific criteria outlined herein:
5 a. New discharge to ground water of industrial waste that
6 contains hazardous constituents in concentrations above natural
7 background levels, listed in the Department publication, G-I
8 Modified Hazardous Constituents List (December 1, 1986)1 hereby
9 adopted and incorporated by reference, shall be prohibited.
10 b. New discharge to ground water of treated domestic waste
11 effluent meeting domestic waste water plant Class I reliability
12 as described in the manual referenced in Section 17-6.040(4)(m),
13 F.A.C.; a pre-treatment program for industrial wastewater; daily
14 monitoring to assure proper treatment plant process control; and,
15 24 hour a day attendance by a certified waste water operator of
16 the class required by Chapter 17-16, F.A.C., and under the
.7 general supervision of a Class A certified waste water operator,
18 shall be allowed to operate provided that the discharge from such
19 plant shall meet the ground water criteria as specified in
20 Section 17-3.404, F.A.C., prior to discharge (end of pipe),
21 unless the installation can affirmatively demonstrate that the
22 criteria are being met prior to contact with ground water. An
23 example of the latter is nitrogen removal through the root zone
24 which reduces the level of nitrate to meet the ground water
25 standard. Smaller domestic wastewater plants of less than
26 100,000 qpd permitted capacity shall provide attendance by the
27 appropriate certified waste water operator as required by Chapter
28 17-16, F.A.C., for 16 hours a day, from 5 a.m. to 9 p.m. Treated
(-"9 domestic waste effluent discharge in G-I areas shall employ land
30 application and shall be restricted to slow-rate infiltration
31 methods, except as provided in c. below.
c. New discharge of treated domestic waste effluent to
wetlands located within G-I zones of protection shall meet the
requirements in b. above for the five year zone of protection and
shall be prohibited in the 200 foot zone of protection.
d. Construction and operation of new sanitary landfills
shall be prohibited.
2. Existing discharge to ground water within G-I zones of
protection shall comply with the current Class G-II criteria,
including zone of discharge requirements, provided that more
stringent monitoring requirements may be implemented. More
stringent monitoring requirements may include increased
monitoring frequency, increased number of parameters, or
increased number of monitoring wells. Such determinations will
be made by the Department on a case-by-case basis by considering
soil conditions, quality and volume of the waste stream, and the
point of discharge.
(b) Stormwater Discharge to G-I Ground Water.
1. Within the five year zone of protection:
a. A new industrial facility listed on the Department's
publication, G-I Modified Standard Industrial Code (December 1,
1986)1, hereby adopted and incorporated by reference, which
stores, handles, uses, or produces hazardous constituents
appearing in the G-I Modified Hazardous Constituents List
(December 1, 1986)1 discharging to a stormwater facility within
a five year zone of protection shall be prohibited unless
containers, paving, curbing, or other measures are provided and
are of adequate size such that any release of hazardous

Department district offices, and copies may be obtained from the
Department's Office of Public Information, 2600 Blair Stone Road,
Tallahassee, Florida 32399-2400.
1 constituents would be totally contained and prevented from coming
2 into contact with stormwater, surface water, or the around.
3 Application of pesticides as part of normal agricultural
S4 practices in accordance with the label and Department of
5 Agriculture and Consumer Services rule are not prohibited.
6 Developments which are exclusively residential shall not be
7 included in the prohibition.
8 b. Discharge from new stormwater facilities, other than in
9 a. above, serving an area forty acres or larger with a forty
10 percent impervious surface excluding building tops shall be
11 required to monitor the discharge to ground water according to
12 Section 17-4.245(6), F.A.C. Such facilities may be required to
13 implement more stringent monitoring requirements which may
14 include increased monitoring frequency, increased number of
15 parameters, or increased number of wells. Such determination
16 will be made by the Department, or a water management district to
w*7 which stormwater has been delegated, on a case-by-case basis by
18 considering soil conditions, quality and volume of the waste
19 stream, and the point of discharge.
20 c. New discharge to ground water through sinkholes and
21 wells shall be prohibited.
22 d. Installations and facilities not included in a.-c. above
23 shall be exempted from G-I criteria.
24 e. The Department or a water management district to which
25 permitting authority under Chapter 17-25, F.A.C., has been
26 delegated shall, consistent with Section 17-4.245(3)(b), F.A.C.,
27 review and approve as appropriate the preventative measures as
28 part of the stormwater permit application or surface water
19 management permit application.
