7.3 Northern Tama, Bay W.ateZ Use Cantion Area Jan. 25, 1991

The Governing Board declared portions of Hillsborough, Pasco, and
Pinellas Counties a Water Use Caution Area (WUCA) on June 28, 1989.
The area designated is shown in Figure 7.3-1; the legal description
is provided in Rule 40D-2.801(3)(c). As of the effective date of
the Rule, all existing water use permits within the Water Use
Caution Area are modified to incorporate the applicable measures
and conditions described below. Valid permits, legally in effect
as of the effective date of the Rule are hereafter referred to as
existing permits. Applicable permit conditions, as specified below,
are incorporated into all water use permits in the Water Use
Caution Area and shall be placed on new permits issued within the
area. However, both the language and the application of any permit
conditions listed may be modified when appropriate.
These portions of the Basis of Review for the Northern Tampa Bay
Water 'Use Caution Area are intended to supplement the other
provisions of the Basis of Review and are not intended to supersede
or replace them. If there is a conflict between requirements, the
more stringent provision shall prevail.

I. Public Supply

The following water conservation requirements shall apply to
all public supply utilities or suppliers, including wholesale
customers supplied by. anther entity, wbhch obtain water
either indirectly or directly under water use permits within
the Water Use Caution Area, regardless of the naUmes) on the
water use permit. A wholesale public supply customer shall
be required to obtain a separate permit to effect the
conservation requirements unless the quantity supplied by the
wholesaler is less than 25,000 gallons per day on an annual
average basis and the per-capita daily. water use of the
wholesale customer is less than the applicable per capital
daily water use requirement. Permittees whose permitted
annual average quantity is less than 25,000 gallons per day
and whose per-capita daily water use is less than the
applicable per-capita daily water use requirement are exempted
from the residential water use report, rate structure, and
water audit requirements.
A. Per-Capita Use

Per-capita daily water use is defined as population-related
withdrawals associated with residential, business,
institutional, industrial, miscellaneous metered, and
unaccounted uses. Permittees with per-capita daily water use
which is skewed by the demands of significant water uses can
deduct these uses provided that these uses are separately
accounted. Generally, the formula used .for determining
gallons per day per capital is as follows: total withdrawal


B-127






0 9


minus significant uses, environmental mitigation, and
treatment losses, divided by the population served (adjusted
for seasonal ande tourist populations, if appropriate). For
interconnected systems, incoming transfers and wholesale
purchases of water shall be added to withdrawals; outgoing
transfers and wholesale sales of water shall be deducted from
withdrawals.
A significant use, which may be deducted, is defined as an
individual non-residential customer using 25,000 gallons per
day or greater on an annual average basis, or ai individual
non-residential customer Whose use represents greater than
five percent of the utility's -annual water use.
Any uses which are deducted from the per-capita daily water
use based on the above guidelines shall be supported with
Documentation of the use and associated quantities.
Additionally, all significant deducted uses must be accounted
for in a water conservation plan developed -by the
applicant/permittee which includes specific water conservation
goals for each use or type of use. Environmental mitigation
quantities permitted by the District and treatment losses such
as desalination reject water and sand-filtration backwash
water shall be identified and reported separately, and shall
not be included in the calculation of per-capita use.
Treatment losses for each: type of treatment plant (e.g.
desalination, sand filtration) shall be calculated separately.
Treatment losses ae- calculated as raw water into the plant
minus treated water out of the plant.
All permittees shall calculate and report gross per-capita
water usage as outlined above However, for purposes of
compliance with per-capita requirements, a permitted may also
calculate and report tr per-capita se rate that reflects
incentives for reuse and the use of desalination sources.
For compliance purposes, a permitted may deduct the quantity
of reclaimed water delivered for uses "not served by the
permittee's water utility. Allowable deductions shall be
limited to those quantities that would normally be permitted
for the activity (e.g. if reuse is supplied for golf course
irrigation, the acreage of greens, tees, and fairways must be
submitted, and the quantity of potable water that would be
permitted for that use would be deducted from the total
quantity used for compliance with the per-capita requirement).
Where the ground-water source to be permitted or replaced is
of Significantly lower water quality but is suitable for the
intended use, the reuse credit may not be claimed (e.g.
reclaimed water replaces saline withdrawals used for
irrigation, where the saline water is suitable for the
irrigation and thd withdrawals -do not threaten the water
resources). Reclaimed water is wastewater that has received


B-128









at least secondary treatment and is reused for a beneficial
purpose. A permitted may deduct only the quantity of
reclaimed water under, he control of the utility, supplier,
or governmental unit holding the water use permit.
For compliance purposes, a permitted may deduct 50 of the
quantity of finished water from desalination sources prior to
blending with water derived from freshwater sources. A
desalination source is 4 plant which remove salts and other
chemicals from highly mineralized water of greater than 500
mg/1 Total.Dissolved Solids. ,
Acceptable data sources for service area population and
seasonal/tourist population adjustments are described in
section 3.6 of the Basis of Review. If the service area
population is developed using a person per unit factor, then
calculation of the factor must be documented indicating that
the factor is. reasonable for the service area. In.cases where
seasonal adjustment is appropriate and the service area is
smaller than the area covered by the applicable comprehensive
or regional plan then the same seasonal .adjstment factors
used to adjust the permanent population of the planning area
may be: applied to the peaanent population of the service
area. Other methods of calculating service area population
may be used provided that the methodology is accepted by the
District as appropriate for the- service area. estimates of
population shall be based on information developed or reported
no more than twelve months prior to the applicable management
period. When reporting per capital rates, the service area of
a permitted public supply utility or supplier shall consist
- of the area which the permitted exerts management control for
public water supply
January 1. 1993 Managaemnt Period
Public Supply uses within the Water Use Caution Area shall
meet, at a minimum, an overall maximum per capital water use
rate .of 150 gallons per day for the January 1, 1993 management
period. This standard shall remain in effect until modified
by rule. However, for planning purposes, also listed are per-
capita goals- for future management periods.- Public supply
permittees shall also document the quantities supplied to
deducted uses, and the water conservation measures employed
for deducted significant uses.
January 1. 1997 Manacenent iodd
Based on information collected for the period 1990-1992, the
per-capita rate will be developed for the January 1, 1997
management period and adopted by rule with sufficient time
for permittees to prepare for the 1997 management period.
Based on current information, the per capital water use rate
goal would be 140 gallons per day.

January, 1 2001. Management period
Based on information collectodt for the period 1993-199t, the
per-capita rate will be. developed for the January 1, 2001
management period and adopted by rule with sufficient time
for permittees to prepare for the 2001 management period.
Based on current information, the per capital water use rate
goal would be 130 gallons per" day. -
Januarv 1,. 2011 Management period
Bated sh information collected for the period 1997-2000, the
per-capita rate will be developed o~r the January .e1, 2011
management period and adopted by rule with sufficient time
for permittees to prepare for theta 2011 management period.
Based on current information, the per-capita water use rate
goal would be 130 gallons per day.

This requirement shall be implemented by applying the
following permit conditions to all existing and new public
supply permits
1. By January L, 1993., the Permittee shall achieve a per
capital water rate equal to or les than 150 gpdt This
standard shall remain in: affect until modified by rule.
For planning purposes, listed below are per-capita goals
for future managem t periods. These goals may be
established as requirements through v future rulemaking by
the Distriot:
a. By January 1, 1997, the Distriot aay establish a
new per capital water use sta4dar Based on current
information, the per capital' wter use goal may be
established by rule at 140 gpd;
b. By: January- 1, 201, the District a.y establish a
.aew per capita water usee standards. a. ed on
current information, the per capital water use goal
may be established by rule at 130 gpd; aBnd,-
c. By January :, 2011, the District may establish a
new per capital water *se standard. Bas e on current
information,, the per capital water use goal may be
established by rule at 130 gp
2. By April 1 of each yoer for the preceding fiscal year
(October through Septmber 30), the permitted shall
submit a report detailing:
a* The population served
b. Significant deducted uses, the associated quantity,
and conservation measures applied t6 these uses;
o. Total withdrawals;

transfers of watoe and lwhlesle pureohaes and sales
of water, with quantities determined at the
supplier* departuse peitt.
g. Documentation of rouse and desalination oredits, if
taken.

As of auiaary 1, 1993, if the petaittee does not achieve
the speoified per caita rates,a the report shall
document why these rta and reqtafeikts were not
aohievablo, omeares take to att; t mretaing thea, and
a plan to bring the permit into ceaplianae. This report
is subject to Distriot approval. i2 the report is not
approved, the Pormittee is in violation of the Water Use
Permit. -

3. Tho Distriet will evalmate information sutmitted by
Pezaittoee who do not ao weve those reqairMeats to
determine whether the lank of adhieveMat is jstifiable
and a variance is vrranmted. -ammittees a*y justify lack
of achievenmentby Bafemtingq tntoa wabbr edsu, such
as larger than average lot gioes with geOater water
irrigation needs than natal-sised ltai. levere, even
with such documented justification, phased retuotions in
water use sill b required 'lesv tBhe District
determines that water usage was reasdmable under the
circumstances reported and that further k*twetions are
not feasible. For such Permittees, on a case-by-case
basis, individual water oedu\o vatio.n ruirements may be
developed fo* eadhb managem t period.

Prior to the 1997, 2001- and 2011 management periods,
the Distriet'.wll reassess the peo-oepti and other uses
conservation gets. S a result of this reassessment,
these goal ray be adjusted tpwad eo downward through
rulemakiag and will become sreqtteaets.

B. Water Conservina Rate Stxu-tura

Each water supply utility within the Water Use Caution Area
shall adopt a water-conserving rate structure by January 1,
1993. This requirement shtll be mplmeanteod by applying the
following permit oridition to all exiting public supply
permits: :
The Permittee shall adept a water conservation oriented
rate structure no later teha January 1, 1993. If the
Pemittee already has a wter conservation oriented rate
structure, a description of the structure, any Wapporting
documentation, and a report on the effectiveness of the


B-131









rate structure shall be isubmtted l by January 1, 1993.
Permittees that adopt, a water -oaservation oriented rate
structure pusuant- to, .his rple shall submit the above-
listed information by July 1, 1993.

New public supply permit shall receive the following permit
Condition ,
The Permittee shall adopt a water conservation oriented
a *e stTautut e ao leter than two years from the date of
Spe"it isauan~e. he Peritt ee shall submit a report
Sd saqbibg the gate structure and its estimated
SefetA4veness within 60 days following adoption.

Waer Audit
All water supply utilities shall implement water audit
programs by January 1, 1993. A thorough water audit can
identify what is caupsID g unaccounted water and alert the
Utility to the possibilityy of significant losses in the
distribution system. Unacocunted water can be attributed to
a. Variety of causes,, including ; unauthorized uses, line
flushb~g, authorized nuatered uses, under-registration of
Peters, fire flows, and leaks. Any losses that are measured
.and documPnted. ar not considered unaccounted water.
This requirement shall be imp rented by. applying the
following permit condition. to al existing Public Supply
Permits: .

Th 9permittee .shll cna4 uq ai iter au4ita of the water
supply system d4rag h -9 & Ouaagesent period. The initial
audit shall be conducted no later than January 1, 1993.
Water audts which identify a,greater than 12 percent
; unaeqonted for water sOba! "be., followed by appropriate
S rewe4Kal action. Audit* shall e completed and reports
Sdoeumenting the results of te audit shall be submitted
as 4n lemeat of, tbheo repot required in. the per capital
condition to the District by the following dates:
January 1, 19931 Ja~uaxy 1, 997 January .1, 2001; and
January 1, 2011. Water audit reports shall include a
schedule for remedial action i f eded.
Large, complex water supply systePs may conduct the audit in
phases, with prior, approval by the District. A, modified
version shall be applied to new permits, replacing the initial
audit date with a date two years forward from the permit
v-iseuance date. Prior to 4Ach management period, the District
will reassess the unaccounted-for water standard of 12%, and
a," .adjust this standard upward or downward through
rulemaking.

D. Residential Water Use Reorts
Beginning April 1, 1993, public supply permittees` shall be
required to annually report residential water use by type of
dwelling unit. Residential dwelling units shall be classified
into single family, multi-family (twO or bore dwelling units),
and mobile homes. Residential water use consmits of the
indoor and outdoor water uses associated with these classes
of dwelling units, including irrigation uses, whether
separately metered or not. The ermittee shall document the
methodology used to determine the number of dwelling units by
type and their quantities used. EstiMarte of'water use based
upon meter size Uay be inaccurate and will not be accepted.
This requirement shall be implemented by applying the
following permit condition to all public supply permits:
eginnzig in 1993, by April 1 of ea* -year for the
probedqag fiscal year (OCtob*r 1 tbro e Stember 30),
the perraftte shall submit a residential water use report
detailing:
a, The number of single fraily dwelling units served
agd their total water s,
b. The nauber of. mlti.-ifaly dwelling units served
and their total water use,
a. The number of mobile hoies served and their total
water use.
Residential water use quantities shall flolude both the
indoor and Mtdoor water ses associated with the
dvell tag umits, iAoludig irridation water.
iU. Agricultaue
A. Irrigation Water Use Allotments
The District allocates agricultural irrigation-related water
use based on a modified Blaney-cfiddle Wodel and other* methods
as described below. For each individual crop tye, the
permitted shall not exceed the quantity determined by
multiplying the total irrigated acres by the total allocated
inches per irrigated acre per season. Allocated inches per
irrigated acre per season are deterviied separately for three
major r atg ories of water use, and the sum e-.uat' the total
allocated inches per irrigated acre per s.eaon. An irrigated
acre, hereafter referred to as "acre, isdefined as the gross
acreage inder cultivation, including areas used for water
conveyance such as ditches, but excluding uncultivated areas
such as wetlands, retention ponds, and perimeter drainage
ditches. Other non-irrigation related water uses shall be
permitted in accordance with section 3.3, Basis of Review.


B-133









As a guide for permit applicants and permittees, total
allocated inches per acre per season, for citrus in the
Northern Tampa Bay WUCA are listed in tables provided in
Design Aid 4, Part C, Water,- Use Permit Information Manual.
For creop, soil types, planting dates, and length of growing
season not listed in those,,tables, an applicant or permitted
may obtain the total,, allocated inches .per acre per season
utilizing procedures described in Design Aid 4 or complete
the Agricultural Water Allotment Form and suaiiit it to the
District. The District will complete and return the form
calculating total allocated, inchs per acre. per season per
crop based on the inCoYaation provided. A permit applicant
or permitted may use alternative methods for calculating water
use needs subject to District approval..
A key component in calculating tot al located inches per acre
per season is the assigned "'rrigatiop water use efficiency,"
hereafter referred to as "efi cency". Efficiency is defined
as the ratio of the volume of .water bhneficially used to the
volume delivered from the irrigation system. For. many crops,
it is common for different irrigation systems and practices
..,tg be employed for different water pea (e.g. a tomato grower
may use seepage irrigatoiQ for field preparation and drip
irrigation for supplemental irrigation). In recognition of
these differences, the District applies separate assigned
efficiencies to different water irrigation-related water uses.
The three major categories of agricultural irrigation-related
water use are: 1) supplemental irrigat4io (the water
delivered to satisfy thq evapotrappirationaX need of the
crop); 2) field prqparatioQp/rop establishmentt (the water
delivered for tilling, bedding, fumigation, and planting); and
3) other water uses (i.e. frost and freeze.protection, heat
stress relief, chemical application, irrigation system
flushing and maintenance, and leaching, of salts from the root
zone). The District has assigned minimum efficiency standards
for supplemental and field preparation/crop establishment
irrigation requirements.. Th t standards are listed later in
this section. Design Aid 4, Part C, Water Use Permit
Information Manual, describes in detail a methodlcpgy for
calculating allotted inces per acre per season for
supplemental irrigation (sjplementaJ irrigation requirements
divided by the assigned ef f~iency, standard) and the allocated
inches per acre per season for field .preparation/crop
establishment (fiqld preparation/crop ostabjl hment irrigation
requirements divided .by the assigned efficiency standard).
As specified in section 3.3 of the Bapis, other information
and methods may be considered as supported by. the facts in
individual cases.


B7-134




." ^-^ .:




Other water uses are permitted on an individual basis as
follows:
1. Chemigation,-irrigation system flushing and maintenance,
heat stress relief and leaching of slts the total
allocated inches per acre. per season for these uses is
equal to ten (10) percent of the allocated Inches per
acre per season of the supplemental irrigation
requirement for crops irrigated with a micro irrigation
system, and five (I) percent aof th allocated ibahes per
acre per season of the supplemental irrigation require-
ment for crops irrigated with iall other irrigation

2. Frost/freeze protection The District allows irrigation
for frost/freeze protection proVided that: 1) the maximum
daily quantity listed on the permit is not exceeded; 2)
irrigation for this p.6tpee willinot cause water to go
to waste and, 3) perittees whose a aannul rage daily
permitted? water use is eal to oi exceeds 100,000 gpd
shall document and report the beginning and ending hours
and dates, and -inches per acre applied for such purpose.
The allocated inches per acre per season per crop for
supplemental and field preparation/crop establishment for the
January 1, 1993, management period will be based on the
following minimum assigned efficiency standards. These
standards shall remain in effect until modified by rule.
However, for planning purposes, also listed are assigned
efficiency standard goals for future management periods.

B. Monitoring a Reauirements for Agricultural .ater IIsa

To ensure compliance with the total allocated inches per acre per
season per crop, the District e1qq*res the foeloving data to be
submitted* Although the permitted is not, r.equlred to be in
compliance with allocation requirements until. January 1, 199.3,
the permitted is required to submit these data beginning with the
first appropriate date in 1991, as specified in the permit

to District approval If t:he report is not approved, the
Permittee is in violation of the Water Use Permit.

a The Distriet will evaluate information submitted by Permittees
who exceed their allocated quantities to determine whether the
lack of achievement is justifiable and a variance is
warranted. Permittees may justfy lack f aehevement by
documenting unusual water needs, suoh as unusual soil or
weather 1nditions creating greater irrigation needs than
oral. however, even with suh dmourated justification,
phased redu tions n water ase shall be r equird tle a the
Distxiat determines that water aMge was -rease~- hb wader the
oirounstanc s reported and that further sedUltions are not
feasible. For sek SeuMiteet ea a on a *ly-ome basis,
individual effioienoy criteria may be developed for each
management period.
3. Compliance with allocated quantities sall be determined by
comparing actual use to the calculated quanltites for eaoh
individual crop on a per season basis. Seasonal crops will
be compared on a seasonal basis (e.g. spring tomato
requirements based on the calculated inohee peo season), and
perennial oeops will be. omptare on a annual basis (e.g.
citrus requirements based on the calculated inches per year).
The District will 'reassess the efficiency goals prior to
implementation. As a result-of third reasseerfest, these goals
may be adjusted upward or downward through rulemaking.
C. Other AaricUltural Water Uses

Quantities for other uses' not related to plant preparation and
irrigation demand shall be documented separately. Such uses may
include filling of spray tanks, livestock needs, cleaning, and
frost freeze protection.

III. Recreational. Industrial, and Mining

A. ConnraMtion Plan

All permit applicants for recreational/aesthetic,
industrial/commercial and mining/devatering uses are required to
submit a water conservation plan specifically addressing
recycling, reuse and landscaping to. the "District at time of
application. Existing permittees shall submit a co.e rvation plan
by July 31; 1992. The following condition shall be placed on all
appropriate permits, and the elements listed in the condition
below shall be addressed in all new applications:
The permitted shall submit to the Distriot a conservation plan
by July 31, 1992. This plan shall include documentation and
assessment of current and potential internal reuse, as well

areas .such as tees and greens. -.
4. sRedteing the frequany of. irrigation for fairways.
5. Elimination of irrigation of roughs.
IV. Auamentation

Augmentation means using one source of water to supplement
another. Typically, augmentation involves using ground water to
supplment the surface water levels of lakes, ponds and wetlands.
Augmentati.e may be required by. the. District to mitigate the
impacts of withdrawals, or it may be requested by an applicant who
wishes to raise surface-water1eals. Augmentation is permittable
provided that the benefits otweiv h any adverse inmpets to' gTund-
or surface-water resource, depwening on the specific situation.
Augmentation, for maintenance :of l.ak and wetland, natural .habitat
can be permitted as long as no significant adverse impacts result
from the withdrawal.. Augmentation may be allowed provided that
(1) alternative solutions. have been addressed, f2) the' teed for
such augantation has been :established, (3) withdrawals for
augmentation do not cause significant adverse impacts, and (4)


, B-142




A A 11 I j h I


measures are taken to allow the surface water level to fluctuate
seasonally as described in Section 4.12.2.d. of the Basi of
Review. Augmentation above District-establt64ed applicable
minimum water levels is prohibited. Ihxium rouid- water
augmentation levels for lakes currently below established
minimum water levels will be based on recent historical levels.
Augmentation for purely aesthetic purpo se, such as for creating
and maintaining water levels in costrudted pojds shall not be
permitted. Existing permits which aiclude iestieti augmentation
may be.rwnewed only if the criteria Of Section 4.12.2.C. through
i. are implemented. Reuse .of water through tail-water recovery
ponds in efficiently managed systems is encouraged and is not
considered augmentation.
V. L~ae ..ia

A stressed condition for a lake is defined to be chronic
fluctuation below the normal range of lake level fluctuations.
For lakes with District-established management levels, a stressed
condition is a chronic fluctuation below the minimum low
management level. For those lakes without established management
levels, stressed conditions shall be determined on a case-by-case
basis through site investigation by District staff during the
permit evaluation process. The District maintains a list of lakes
within the WUCA which have been determined to be stressed.

A. Stressed Lakes New Wthdrawals
Due to cumulative ground water and surface water withdrawal
impacts, new withdrawals from stressed lakes shall not be
permitted.
B. Stressed Lakes Existing Withdrawas

Existing permitted surface withdrawals from stressed lakes shall
be abandoned or replaced with an alternate source by September
30, 1993. Existing and new permitted withdrawals from akes which
are determined by the District to be stressed following the
implementation of the WUCA Rule shall abandon or replace these
withdrawals with alternate sources within three years of the
designation of the stressed lake.
This requirement shall be implemented for all existing permits
which include surface water withdrawals from stressed lakes by
applying the following permit condition:
All existing surface water withdrawals from stressed lakes
shall be abandoned or replaced with a surfioial o Flooridan
aquifer ground-water source, or a reuse source, by September
30, 1993. Such replacement shall require a modiftiation of
the Water Use Permit.

information, the applicant shall be required to prepare a cost-
estimate for connection.

Permittees capable of using reclaimed water will be required to
accept it when. it becomes available, provided that the quantity
and quality are acceptable for the intended use, as determined by
the District. If the reclaimed water generator provides the reuse
connection, acceptance is required, provided that the qantity and
quality of the reclaimed water are acceptable for the intended
use, as determined by the Dirtriat. If the Permittee must pay for
all or a part of the cost sof connection to the reclaimed water
source, the permitted may present an economic feasibility report
to the District demonstrating whether connection is feasible.
