TOWN OF ORO VALLEY
COUNCIL COMMUNICATION MEETING DATE: February 10, 2003
TO: HONORABLE MAYOR& COUNCIL
FROM: Alan Forrest,Water Utility Director
SUBJECT: Oro Valley Water Utility Drought Policy Review
SUMMARY:
In recognition of the current drought Arizona is experiencing and the impact such drought conditions can have
on the operations of a public water system, the Mayor and Council instructed staff to develop a policy to
address such situations. During the past several months, staff has researched drought and water shortage
policies adopted by communities in Arizona and has, with the help of the Water Utility Commission,
developed a new water conservation and use reduction policy for the Mayor and Council's consideration.
This new policy directs the Water Utility to implement specific rules, regulations, penalties and plans for water
conservation during times of drought and water shortages. In general, the policy clearly identifies the Town's
priorities for potable water demand and corresponding conservation requirements as water demand approaches
and exceeds water production capability. A copy of the proposed changes to the Water Code to implement this
policy are attached for your information.
The Water Utility Commission has thoroughly reviewed the attached document and at their meeting of January
13, 2003 voted unanimously to recommend approval by the Mayor and Council. Along with Water Utility
Staff, Commission members will be present at your meeting of February 10th to help answer any questions you
may have regarding this proposed code revision.

Furthermore, because of the arid conditions present in the area, it is the policy of the Town of
Oro Valley to encourage its water users to always conserve water voluntarily to the maximum
extent practicable. The Town of Oro Valley deems it necessary to establish policies, rules,
regulations, penalties and plans for water conservation within the Town to be implemented by
Oro Valley Water Utility customers during water shortages as defined herein.
15-18-2 Declaration of Policy
It is hereby declared that, because of the water shortage conditions experienced in the Town of
Oro Valley, the general welfare requires that all the water resources available to the Town be put
to the maximum beneficial use to the extent to which they are capable, and that waste, excessive
use, or unreasonable method of use of water be prevented, and that conservation of water be
exercised in the interests of the Town of Oro Valley and for the public welfare.
15-18-3 Water Conservation Compliance
It shall be unlawful for any customer of the Town of Oro Valley Water Utility to and no
customer of the Town of Oro Valley Water Utility shall knowingly make, cause, use or permit
the use of water from the Town for residential, commercial, industrial, agricultural, irrigation or
.
any other purpose in a manner contrary to any provisions of this Code, or in an amount in excess
of that use permitted under any Resource Status Level declared in accordance with this Code.

15-18-5 Termination of Water Service for Violation
If and when the Water Utility Director, or a designated representative, becomes aware of any
violation of any use reduction regulation pertaining to water use or misuse, the Water Utility
Director, or a designated representative, shall have authority to take actions, including mandatory
measures up to and including disconnection of service, and other such enforcement actions as are
required or deemed necessary to assure compliance with the use reduction plan. In notification
of such a violation, a written notice shall be placed on the property where the violation occurred;
and a duplicate shall be mailed to the billing account address for the service where the violation
occurs, and to any other person known to the Water Utility who is responsible for the violation or
its correction. Said notice shall describe the violation and order that it be corrected, caused or
abated immediately or within such specified time as the Water Utility determines is reasonable
under the circumstances. If said order is not complied with, the Water Utility may forthwith
disconnect the service where the violation occurs. If a service is disconnected, assessment of a
re-connection fee to be determined by the Water Utility will be assessed and collected before
service is restored. Said fee shall be in addition to other fees or charges imposed for
disconnection or reconnection of service.
Upon a second violation at the same property or by the responsible party, disconnection may be
ordered immediately, and the service shall not be reconnected unless a device supplied by the
Water Utility that will restrict the flow of water to said service is installed. Furthermore a fee for
reconnection may be imposed in addition to other fees or charges imposed by the disconnection
and reconnection of service.
In addition to any other legal or equitable remedy to enforce the provisions of this Code, the
Town of Oro Valley may terminate or suspend water service to property owned or controlled by
any party in violation of any provision in this Code. The Water Utility Director, or a designated
representative, may cause a notice of water termination to be served upon the violating party
stating that service will be discontinued in a predetermined number of days unless a hearing is
requested. A hearing may be requested by delivery of a request in writing to the Town Manager,
which shall be received by the Town Manager on or before the expiration of said specified
number days. If a hearing is requested, the Town Manager shall convene a hearing within three
(3) business days of the written request. The requesting party may appear before the Town
Manager and may present such evidence and reasons such party may have for not effectuating a
termination or suspension of water service and may bring to the hearing such other persons or
evidence as such party may desire. After hearing, and upon finding that such a violation has
occurred, the Town Manager may order that water service be terminated or suspended pending
compliance with the provisions in this Code. Termination of water service and reconnection of
service is subject to all applicable charges, fees and penalties.
15-18-6 Variance
The Water Utility Director, or a designated representative, may in writing, grant variances to
persons who apply for usages of water not in compliance with the water use reduction programs
described in 15-18-4 F. These variances may be granted if it is found that such water use is
necessary to prevent an emergency condition relating to health, safety and general welfare or
essential governmental services such as police, fire, and similar emergency services; or for
customers who have made every reasonable effort to reduce water use yet are still prevented
from compliance for reasons beyond their control. Efforts made to conserve water at the onset of
drought conditions or periods of water shortage may be considered in granting said variance.
15-18-7 Penalties
Any violation of any provision in this Code shall be a civil violation and shall be subject to a
civil sanction not less than Fifty Dollars ($50.00) and not to exceed Two Thousand Five Hundred
Dollars ($2,500.00) for each day that the violation continues. The imposition of a civil sanction
shall not be suspended.

ATTACHMENT II — Effluent Credit Calculations
Introduction
Formula development is presented in several steps. The first characterizes the total volume of
effluent available.The total volume of effluent can be characterized as having entitlement by a
particular entity. Each entity can use their entitled volume directly or discharge it to the channel
for managed recharge. If the water is discharged to the channel, the volume recharged is
apportioned based on an"in-channel" entitlement in order to accrue individual recharge credits.
The volume of effluent entitled to SAWRSA is not made subject to any physical losses. This
effluent is recharged for credit accrual (and equivalent aquifer cut) or passes out of the project at
the Pima/Pinal County Line. Credits that accrue between Ina Road and the Trico gage are
calculated separately from credits accrued between Trico and the county line in the event that the
proposed manual gaging at the county line is not accepted within the permit.The following
sections describe the proposed formulas.
Effluent Production
The total effluent produced from the Metropolitan Area wastewater plants (Er) is equal to the
amount of effluent discharged to the Santa Cruz River(EscR) plus the amount of effluent used
directly by the cooperators or other entities (ED). Direct use by cooperators includes effluent
diverted from the plants prior to discharge to the river and/or any downstream diversions.
Downstream diversions by other entities are reflected in the term DD.
EP=EsCR+ED
ED=EDT+EDO+EDM+EDP+EDS+EDNEW+CEP+DD
where:
EP=Total effluent produced from all Metropolitan Area wastewater plants'.
EsCR=Total effluent discharged to, and allowed to remain in the Santa Cruz River
(physical losses not deducted).
ED=Total effluent directly reused and/or diverted from the Santa Cruz River.
EDT=Direct and downstream diversions of effluent entitled to City of Tucson.
EDo=Direct and downstream diversions of effluent entitled to Oro Valley.
EDM=Direct and downstream diversions of effluent entitled to MDWID.
EDNew=Direct and downstream diversions of effluent entitled to New cooperator.
EDP=Direct and downstream diversions of effluent entitled to Pima County.
EDs=Direct and downstream diversions of effluent entitled to SAWRSA.
CEP=Conservation Effluent Pool (up to 10,000 AF/YR).
DD=Downstream diversions of effluent by entities other than the cooperators.
Individual Effluent Entitlement of Effluent Production
The total effluent produced (Er) can be used for SAWRSA (S), the Conservation Effluent Pool
(CEP), and individual entitlements for each cooperator. Individual entitlements are a function of
gross effluent produced.Details of the individual entitlements are based on existing IGAs (i.e.,
OE is equivalent to Step Four(Exhibit 3 of City of Tucson—Town of Oro Valley Inter-
governmental Agreement Relating to Effluent)).
Er=S +CEP+TE+OE+ME+PE+NewE
where:

TE=Net effluent entitled by City of Tucson
OE=Net effluent entitled by Town of Oro Valley'
ME=Net effluent entitled by MDWID
PE=Net effluent entitled by Pima County
NewE=Net effluent entitled by New Cooperator
■ Gross Effluent Calculations
The first step is to determine the `gross' effluent entitlements of Oro Valley, Metro Water, and
"New"cooperators subject to the IGA's with Tucson.
L=Ep/I
OGAE=Qov * F* L
MGAE= QMw * F* L
NewGAE=QNEW * F* L
where:
L=Loss Factor%of Effluent remaining after Metropolitan Area wastewater plants3.
Ep=Total effluent produced from all Metropolitan Area wastewater plants.
I=Quantity of water delivered to Metropolitan Area wastewater treatment plants4.
F=0.62"Factor loss of waters produced and returned to the Metropolitan Area
wastewater plants, applies to IGA members."5
Qov= Quantity of Potable Water delivered to Oro Valley Customers (non-irrigation)6.
QMV= Quantity of Potable Water delivered to Metro Water Customers (non-irrigation).
QNEW=Quantity of Potable Water delivered to New Cooperator Customers (non-
irrigation).
OGAE=gross amount of Effluent derived from the waters of Oro Valley'.
MGAE=gross amount of Effluent derived from the waters of Metro Water.
NewGAE=gross amount of Effluent derived from the waters of New Cooperator.
■ SAWRSA Contributions
Next, the individual contributions to the SAWRSA total are calculated.
OS =(S/Er) * OGAE
MS = (S/EP) * MGAE
NewS = (S/Er) * NewGAE
PS =S * 10%
TS=S —OS—MS—NewS PS
(S =TS +OS +MS +NewS +PS)

MS = SAWRSA contribution from Metro Water.
NewS =SAWRSA contribution from New Cooperator.
PS = SAWRSA contribution from calculation of Pima County effluent entitlement.
TS = SAWRSA contribution from Tucson Water.
• CEP Contributions
Next,the contributions to the Conservation Effluent Pool are calculated.
OCEP=CEP/(Ep—S) * (OGAE—OS)
MCEP=CEP/(EP—S) * (MGAE—MS)
NewCEP=CEP/(EP—S) * (NewGAE—NewS)
PCEP=CEP * 10%
TCEP=CEP—OCEP—MCEP-NewCEP—PCEP
where:
Ep=Total effluent produced from all Metropolitan Area wastewater plants.
S =28,200 AF/YR plus losses (SAWRSA effluent).
CEP=Conservation Effluent Pool (up to 10,000 AF/YR)
OCEP=CEP contribution from Oro Valley9.
MCEP=CEP contribution from Metro Water.
NewCEP=CEP contribution from New Cooperator.
PCEP=CEP contribution from Pima County.
TCEP=CEP contribution from Tucson Water.
• Contributions to Pima County Effluent
Contributions to Pima County Effluent(from the IGA cooperators with Tucson) are calculated.
OPE= (OGAE—OS—OCEP) * 10%
MPE= (MGAE—MS—MCEP) * 10%
NewPE= (NewGAE—NewS—NewCEP) * 10%
where:
OPE=Pima County contribution from Oro Valley lo.
MPE=Pima County contribution from Metro Water.
NewPE=Pima County contribution from New Cooperator.
■ Net Effluent Entitlement
The Net Effluent entitlements for all cooperators are calculated. The SAWRSA and CEP effluent
totals are defined previously. The SAWRSA, CEP, and individual Net Effluent Entitlements sum
to the total effluent produced(Ep).

Managed Recharge, Ina to Trico
Recharge is calculated by the operator of the MUSF and reported to ADWR according to
volumes discharged to the channel and volumes lost from the channel that are not recharged. This
formula calculates the volume recharged in the channel between Ina Road and Trico Road.
ER(Ina-Trico)=ESCR—QTRIc0—EVAP(Cor-Tri)—RIR—RCET
where:
ER (Ina-Trico) =Effluent Recharged in Santa Cruz River between Ina Road and Trico
Road.
Escx=Total effluent discharged to and allowed to remain in the Santa Cruz River(from
Pima County)
QTRico=Surface effluent flow at the Trico stream gage(from USGS)
EVAP (Cor-Trico)=Evapotranspiration Loss for the stretch from Cortaro Road to Trico
Road.
RCET=Volume evaporated between Cortaro Road and Ina Road.
(In the SCRMUSF permit, the evaporation term is calculated for the stretch of river from
Roger Road to Cortaro Road,not Ina Road.This leaves just the evaporation from
Cortaro Road to Trico Road to be considered in the term `EVAP'.
RIR=Volume recharged between Roger Road and Ina Road.
Note: Stormflow events in the Managed Recharge Area need to be addressed in the
facility permit application.
Managed Recharge, Trico to County Line
Recharge is calculated by the operator of the MUSF and reported to ADWR. This formula
calculates the volume recharged in the channel between Trico Road and the Pima/Pinal County
Line.
ER(Trico-CL) =QTRico- QLINE—EVAP(Tri-CL)
where:
ER(Trico-CL) =Effluent Recharged in Santa Cruz River between Trico Road and the
Pima/Pinal County Line.
QTRIc0=Surface effluent flow at the Trico stream gage(from USGS)
ALINE=Surface effluent flow at the Pima/Pinal County Line(Manual Stream Gaging)
EVAP (Trico-CL)=Evapotranspiration Loss for the stretch from Cortaro Road to Trico
Road.
Individual Effluent "In-Channel"Entitlement (Ina to County Line)
The volumes of effluent entitled to each cooperator that is discharged to and allowed to remain in
the Santa Cruz River are calculated. The cooperators' proportioned contributions to the volume of
effluent taken by downstream diversions by non-cooperators is considered. Also, the individual
contributions to physical losses and the effluent recharge between Roger Road and Ina Road is
considered. The sum of the individual "in-channel"entitlements plus physical losses plus the
ATTACHMENT II—Effluent Credit Calculations Page 4 of 8
.
volume recharged between Roger Road and Ina Road is equal to the total effluent in the Santa
Cruz River(EscR)
EscR=EIT+RCET+EVAP (Cor-CL)+RIR
EIT=SIT+TELT+OEIT+MELT+NeWEIT+PEIT
where:
EIT=Effluent available for recharge from Ina to Trico.
TEIT=Effluent discharged to the river entitled to City of Tucson at Ina Road.
OEIT=Effluent discharged to the river entitled to Town of Oro Valley at Ina Road.
MELT=Effluent discharged to the river entitled to MDWID at Ina Road.
NewEIT=Effluent discharged to the river entitled to New Cooperator at Ina Road.
PEIT=Effluent discharged to the river entitled to Pima County at Ina Road.
SIT=Effluent discharged to the river entitled to SAWRSA at Ina Road.

DDNew=New Cooperator contribution to DD.
❑ Individual Contributions to Evaporation
Tucson assumes the evaporation from Roger Road to Cortaro Road as part of SCRMUSF(RCET)
Individual contributions to the evaporation from Cortaro Road to County Line are based on the
proportioned ownership of effluent that is in the river at Ina Road (EIT), except for SAWRSA
effluent:
EVAP (Cor-CL)=EVAP (Cor-Trico)+EVAP(Trico-CL)
EVAP (Cor-CL)=TP2ET+OP2ET+MP2ET+PP2ET+NeWP2ET

Individual Recharge Credits Earned
Based on the percentage of effluent in the river and the volume recharged in the MUSF(ER), the
number of recharge credits accrued by each cooperator is calculated. SAWRSA effluent is not
subject to physical losses; however, it does provide a proportioned share of the effluent that flows
out of the MUSF. Therefore,physical losses are calculated relative to the Cooperators except for
SAWRSA, while the effluent outflowis shared proportionally by all cooperators.

COUNCIL COMMUNICATION
MEETING DATE: February 10, 2003
TO: HONORABLE MAYOR& COUNCIL
FROM: Alan Forrest,Water Utility Director
SUBJECT: Managed In-Channel Effluent Recharge Intergovernmental Agreement
SUMMARY:
As you may recall, Town staff has been
workingwith other water providers and governmental agencies within
the region to develop a managedfacility recharge within the Santa Cruz River channel to begin receiving
recharge credits for effluent discharged into the river. Early in the process, the Marana area expressed
recoveryof these credits within their boundaries. In order to avoid certain.
concerns regarding the potential
involvedparties consented to developing an agreement aimed at resolving
litigation related to these issues,the -
issues upfront in thepermitting process. To this end, a non-binding cooperative agreement
these p .
in -MOU) amongthe parties was entered into last spring. Since that time,
(Memorandum of Understanding
point,theparties have been meeting regularly to negotiate an Intergovernmental
using the MOU as a starting .
issue. At this point we have a Final Draft of the IGA, which is attached for your
Agreement (IGA)to settle the
review. Please
keepin mind the IGA is still in Draft form and may require some minor editing.
During the past deal of activit has occurred relative to permitting this facility: In May, an
application for a facility year a g reat y
permit was filed with the Arizona Department of Water Resources (ADWR); in
p
October, ADWR found permit the to be"complete and correct"; and during the month of December, ADWR
notice of the pendingpermit and no objections were received. At this point, ADWR is
published legal o
expected to issue a draft permit facilityermit this month and after comment from the applicant will issue the permit.
So,the only
thingleft to do is finalize the IGA regarding recovery of effluent credits within the Marana area.
During your study
session on February10th, staff will provide a detailed summary of the IGA and attempt to
answer any questions you mayregarding have the document. In general, the IGA provides for the following:
• Operating procedures for the joint facility
• Cost allocation of facility expenses (capital and O&M)
• Procedu res for calculation and distribution of effluent credits—based on effluent ownership
• Development of a Recovery Plan for the Marana area
• A process for dispute resolution

The following recitals represent the general principles to which the parties have agreed.
1.1 The Local Parties are empowered by A.R.S. Title 11, Chapter 1, Article 3 to enter
into this Intergovernmental Agreement(IGA).
1.2 The Local Parties, being located in the Tucson Active Management Area, rely on
the same aquifers for water supplies and need a dependable long-term water supply
for their residents and customers, have a community of health, safety and welfare
concerns regarding the methods, manner and mechanisms for water management,
including the storage and recovery of Effluent and the mechanisms required to
successfully operate a recharge and recovery system. The Participants
acknowledge that issues of Effluent water quality and water treatment are of
importance to all water users in the region. The Participants further acknowledge
that the region's water users would benefit from coordination of activities and
planning in these areas.
1.3 The Local Parties wish to operate an Effluent recharge and recovery system
consistent with sound long-term aquifer management, preservation of groundwater
quality, and avoidance of the risk of subsidence.
1.4 The Local Parties also wish to manage Effluent recharge and recovery activities in
a manner to protect existing land uses and existing water supplies and to prevent
and, where feasible, to remediate groundwater contamination. The Local Parties
wish to recover Effluent credits within CMID/CWUA and Marana in a manner that
effectively utilizes existing water production assets available to CMID/CWUA or
Marana for recovery.

Effluent Credits shall be distributed on the basis of proportional annual
entitlements to Effluent, as set forth in Attachment II, subject to future Effluent
entitlements consistent with State law.
SECTION VI. DEVELOPMENT OF A RECOVERY PLAN PRIOR TO RECOVERY OF
STORED EFFLUENT FROM THE MARANA-AREA
6.1 No Effluent Credits stored at the Facility shall be Recovered within the Marana-
area through a well with greater than 50 g.p.m. capacity without the adoption of a
Recovery Plan. If the Facility is terminated pursuant to Section 6.4, below,
Participants shall comply with the provisions of Section 6.4.3.
6.2 Following the adoption of this IGA, the Marana-area Recoverers will meet at least
once every eight (8) weeks to make a good faith effort to develop the Recovery
Plan. All Participants may attend these Recovery Plan development meetings. The
Recovery Plan shall be adopted upon unanimous approval of the Authorized
Representatives of the Marana-area Recoverers.
6.3 If the Recovery Plan is not adopted by June 30, 2005, a majority of the
Participants may agree to extend the time to develop the Recovery Plan for no
more than two 12 (twelve) month extension periods, until June 30, 2006, and June
30, 2007.

6.4 If the Recovery Plan is not adopted before June 30, 2005, or within any adopted
12-month extension period, the Participants agree to the following Facility
termination process:
6.4.1 By July 31, 2005, (if no extension is approved), or within 1 month of the
end of any approved 12-month extension period, all Participants shall provide
ADWR with their respective notices to terminate the Facility Permit on the Interim
Termination Date.
6.4.2 No less than six (6) months after the Interim Termination Date, the Facility
Operator shall prepare a final report of Effluent Credits earned and an accounting
of costs and expenses incurred for the Participants. Participants shall reimburse
the Facility Operator for any outstanding costs or assessments in accordance with
this IGA. •
6.4.3 No Effluent Credits stored at the Facility shall be Recovered within the
Marana-area boundaries without the consent of Marana(if Recovery occurs within
the Marana boundaries but without the CMID/CWUA boundaries) or
CM[D/CWUA (if Recovery occurs within the CMID/CWUA boundaries but
without the Marana boundaries), or both Marana and CMID/CWUA.
6.5 The Marana-area Recoverers agree that consent to the Recovery Plan to be
developed pursuant to this section will not be unreasonably withheld.
6.6 The Recovery Plan will, to the greatest extent practicable, be developed in
accordance with the following principles:
6.6.1 Any Recoverer proposing to recover Effluent Credits within the Marana-
area will do so in a manner consistent with sound long-term aquifer management in
the Marana-area, preservation of Marana-area groundwater quality, effective use
of existing Marana-area infrastructure, and avoidance of risk of subsidence in the
Marana-area;
6.6.2 The Recovery Plan will be designed to recover the Effluent actually
recharged in the Facility;
6.6.3 The Recovery Plan will be designed to avoid reaching the groundwater
elevation operational prohibition limits contained in the Facility Permit that apply
to Pima County's Tangerine Landfill. Should it be necessary that Recovery occur
preferentially in the area surrounding the Landfill in order to avoid reaching the
operational prohibition limits, and should the cost of such preferential Recovery be
more than the cost of Recovery without reference to these limits Pima County will
be responsible for the marginal cost difference, on a per-acre foot basis, for such
preferential Recovery. This section shall not be construed to require any
Participant to Recover from the area surrounding the Tangerine Landfill.

DRAFT December 10, 2002
6.6.4 The Recovery Plan will limit the amount of Effluent recovered within the
Safe Harbor of the Facility during any calendar year, to no more than 62.5% of the
total amount of Effluent recharged within the Facility in the previous year; in the
event that the Participants' cumulative recovery within the Safe Harbor of the
Facility may exceed this 62.5% threshold during a particular calendar year, no
single Participant shall have the right to pump more than 62.5% of the Effluent
that the Participant stored in the Facility during the previous calendar year from
within the Safe Harbor of the Facility.
6.6.5 Exception: In the case of a water shortage or water emergency, including
the need to deliver water during shortage years or during interruptions of
Central Arizona Project deliveries, Participants agree to allow short-term
recovery of Effluent Credits in excess of 62.5% of the total amount of
Effluent recharged within the Facility in the previous year. Such recovery
shall minimize detrimental long-term aquifer impacts.
6.6.6 Nothwithstanding Sections 6.6.4 and 6.6.5, Recovery of Effluent Credits
within the Marana-area south of the Rillito Narrows shall not exceed the
amount of Effluent Credits actually recharged within the Marana-area
south of the Rillito Narrows, as calculated over a 10-year rolling average.
6.7 Nothing in this IGA shall prevent any of the Participants from developing Marana-area
recovery plans for the recovery of other water or other recharge credits obtained from
other permitted recharge facilities.
6.8 The adoption of a Recovery Plan shall not preclude the Marana-area Recoverers from
unanimously adopting subsequent amendments to the Recovery Plan.
6.9 In the event Arizona law is altered to eliminate, in whole or in part, the current restriction
on the maximum recovery or accrual of Effluent Credits to 50 % of the recoverable
amount of Effluent stored in the Facility during any calendar year, the Marana-area
Recoverers shall meet and in good faith, discuss whether amendments to the Recovery
Plan and this IGA are appropriate.
7. SECTION VII. RECOVERY OF EFFLUENT CREDITS STORED AT THE FACILITY
7.1. Before seeking any permit for Recovery within the Marana-area, Recoverers will offer
CMID/CWUA or Marana the opportunity to submit a proposal to recover the Effluent
Credits.
7.2. CIV /CWUA or Marana may, at its sole discretion, submit an itemized proposal to
recover all or a portion of the Effluent Credits, in accordance with the Recovery Plan,
within seventy-five (75) days of receipt of the Recoverer's offer to submit. In the
absence of a recovery proposal from CMID/CWUA or Marana, the Recoverer may
proceed with the application for a recovery permit in accordance with the Recovery Plan.
.DOC/2}0C/3}{A00031 1 7.DOC/} 11
DRAFT December 10, 2002
7.3. Within forty five (45) days of submission of CMID/CWUA's or Marana's proposal, the
Recoverer may notify CMID/CWUA or Marana of its acceptance of CMID/CWUA's or
Marana's proposal or provide CMID/CWUA or Marana a good faith itemized estimate of
the costs it expects to incur if the Recoverer constructs and operates the recovery
facilities. Should the Recoverer's estimate for the recovery of the Effluent Credits be less
than the amount of CMID/CWUA's or Marana's proposal, CMID/CWUA or Marana
may, at its sole discretion, submit a revised recovery plan proposal within forty-five (45)
days of receipt of the Recoverer's estimate. Should CMID/CWUA or Marana decline to
match the Recoverer's recovery proposal, the Recoverer may proceed with the
application for a recovery permit in accordance with the Recovery Plan.
7.4. In the event the Recoverer rejects a CMID/CWUA or Marana recovery plan proposal
within the Marana-area that is consistent with the Recovery proposal and costs no more
to implement and operate than the Recoverer's proposal, the Recoverer shall not seek a
permit for Recovery in the Marana-area. Such a proposal will be considered to be
consistent if it: (1) provides: comparable quantity and quality of recovered Effluent to the
Recoverer; (2) costs no more than the Recoverer's proposal; and, (3) provides a similar
timing and pattern of delivery of the Effluent to the place of delivery identified by the
Recoverer. A CMID/CWUA proposal to Recover some or all of the Effluent Credits
actually recharged within the Marana-area south of the Rillito Narrows from locations
north of the Rillito Narrows shall not be a basis for rejecting the CMID/CWUA or
Marana recovery proposal.
7.5. If a Participant wishes to recover Effluent Credits within three (3) miles of the Tohono
O'odham Reservation's exterior boundary, the Participant first shall obtain the consent of
the Tohono O'odham Nation to the location of any recovery well.
7.6. Any transfer or sale of Effluent Credits shall include the limitations on recovery of
Effluent Credits contained in Section 6 and Section 7, above, and otherwise be consistent
with this IGA.
7.7. Other than as provided in this IGA, any Participant may recover Effluent Credits
consistent with applicable Arizona law.
SECTION VIII. FUTURE PLANNING.
8.1 The Participants agree to share available data regarding Effluent water quality and
treatment issues and agree to work cooperatively in their future efforts regarding
these issues.
8.2 The Local Parties agree to develop a specific plan for implementing the
requirements of Section 8.1 within the first twelve (12) months of Facility
operation. If the Local Parties so agree, the Recovery Plan developed pursuant to
Section 6, above, may be substituted for the requirements of this section.

Data Collection / Maintenance:
■ The Operator the facility will be responsible for the collection and maintenance of all data
required by p
ermit. The Operator will have the flexibility to determine
how and where this will occur.
■ The Operator may r for solicit the assistance of selected Participants or qualified
y
consultants to manage all or portions of the data.
■ It is anticipated Operator ated the O erator will create an electronic database that remains
reasonably current and accessible.
• The Operator shall establish methods of securing the database and user access.
• The Operator shall establish methods of confirming data input.
■ The Participants may i ntselect to create a website to assist with the Facility operation,
including data sharing and input;the potential costs for such a site are established
below.
Monitoring:
• The Operator will be responsible allfor monitoring and related data collection that
q
meet
the requirements of the Facility Permit, including water levels measured to one-
tenth nth of a foot, flow measurements within plus or minus 10 percent, and effluent
discharge volumes.
■ Pima County will allow access to water level data(water quality if necessary,
although not an ADWR requirement) collected from existing monitoring wells along
the Santa Cruz River as well as data on effluent discharge volumes. The Operator
will coordinate with the current Pima County Wastewater Management contact
person on data access and retrieval.
■ The Operator will create an alternate monitoring plan that satisfies ADWR's
requirements, should this become necessary.
■ USGS stream-monitoringgauges near the Cortaro and Trico Road bridges will be
The g g and to
measure incoming out oing flows as required by the Facility Permit. The
g
Data Section Chief is the USGS contact person at the Survey's Tucson office (520
670-6671).
■ TheOperator willpursue alternatives to improve the accuracy of the Trico Road
p plus-or-minus to
stream gauge 10% accuracy and will coordinate with the
Participants, especially the City of Tucson.
■ If found acceptable byADWR, a method of measurement would be used to measure
p
flowseriodicall between the Trico Road stream gage and the Pima/Pinal county
p Y
line. Operator The would be responsible for collecting any other required monitoring
data. See Contingencies section for further information.
Expenses / Costs:
The division of capital and annual operation and maintenance costs is shown in the Cost
Estimate of Facility Operation.eration. The initial capital improvements needed to make the
Facility operational include:
1. Modifications to improve the stream gage at the Trico Road bridge to the
plus-or-minus 10% accuracy required by the Facility Permit.
2. Develop storage and recovery database and training
A0003057.DOC/ {A0003115.DOCI}3
Although required, the FacilityOperator may develop a website that would allow
g not p
real-time communication between the Participants.
The Town of Marana and CMID have agreed to pay for $20,000 of the estimated initial
.
capital cost,with the balance to be paid on a proportional basis to the amount of credits
each Storer will earn.
Basic annual O&M costs associated with the Facility, including monthly database
maintenance, annual g reporting requirements, and the collection of monthly water level
p
readingsby will be borne the Facility Operator. Participants will pay an annual fee of
$500 to the Operator toward these costs.
Additional annual O&M costs including special stream gage maintenance, to maintain the
10% accuracy rating,, and transfer of data from the USGS to the Operator. Participants
willpaY for these additional O&M costs based their proportion of the amount of
estimated credits that each Storer will earn. The Facility Operator shall have the
authorityto resolve differences between proportional cost sharing based on the
differences between stored credits and that year's estimated credits.
The Operator shall prepare a draft Annual Budget by October 1 of the preceding year for
p p p
review and approval by the Participants. The Participants shall approve the annual
budget by the end of the current calendar year.
Extraordinarymay costs be incurred during the 20-year life of the project that result from
unexpected events or acts beyond the control of the Participants. These include, but are
not limited to, storm flows which damage stream gage equipment or create stream bed
conditions that adversely impact the 10% accuracy requirement and vandalism of stream
gages or monitor wells. Participants will pay for extraordinary O&M costs based their
proportion of the amount of estimated credits that each Storer will earn. The Facility
Operator shall have the authority to resolve differences between proportional cost sharing
based on the differences between stored credits and that year's estimated credits.

will be completed by the USGS.
The USGS will collect extra measurements each month at the Cortaro
Road stream gage and the Trico Road stream gage. The additional
measurements are needed to increase the accuracy of the measured stream
flow at the site. The flows between the wastewater treatment plants and
the gages are also compared to determine when additional measurements
are needed to improve the accuracy at the gages. $14,000

TOWN OF ORO VALLEY
COUNCIL COMMUNICATION STUDY SESSION: FEBRUARY 10, 2003
TO: HONORABLE MAYOR & COUNCIL
FROM: Jim Hossley
Operations Division Manager
SUBJECT: Proposed Storm Water Program& Estimated Costs
SUMMARY: The Storm Water Utility Commission (SWUC) has
completed the necessary preparations required for meeting the application
deadline for coverage under the NPDES Phase II Municipal General
Permit. This includes preparing a storm water management program with
Best Management Practices (BMP's), measurable goals and an
implementation schedule. Attached is the storm water management
program the SWUC recommends the Town implement and submit to the
Arizona Department of Environmental Quality in fulfillment of the six
Minimum Control Measures required by the NPDES Phase II General
Permit. The attached storm water management program document
addresses each of the six minimum control measures separately. For each
control measure the list of the permit requirements and a narrative of the
Town's approach to the requirements is provided. A table is also included
with BMI''s, measurable goals for each BMP and a schedule for
development of the BMP.
Also attached for discussion is the estimated cost to implement the Town's
storm water program. The attached spread sheet shows the SWUC's cost
estimates to implement the NPDES and Town Wide Drainage programs
from March 2003 through December 2007 (end of the permit period). The
document also shows the estimated personnel time to implement the
programs. Personnel times are divided into Professional, Technical,
Operator, Laborer and Administrative positions. The personnel costs
include salary plus benefits and overhead. The benefits and overhead were
estimated using 33% of the salary.
The total cost to implement the NPDES program alone over the permit
period is estimated to be $1.6 Million. This amounts to approximately
$320,000 per year. To implement the flood control and maintenance
TOWN OF ORO VALLEY
COUNCIL COMMUNICATION Page 2 of 2
programs identified in the Town Wide Drainage project over the same
permit period is $601,086 or $120,217 annually. This cost estimate does
not include any assistance from Pima County Flood Control District to fund
design or construction of projects. Total cost for implementing the
programs is estimated to be $2,197,407 over the permit term or $439,481
annually.
The SWUC and staff are currently preparing a recommended funding
mechanism. This should be ready for Town Council consideration in March
of this year. Additionally, the Notice of Intent for coverage under the
NPDES Phase II Municipal Permit and the necessary program documents
will be ready for submittal to ADEQ by March 10, 2003.

Background letter, labeled Town of Oro
Valley, Arizona, Stormwater management
Plan
TOWN OF ORO VALLEY, ARIZONA
STORMWATER MANAGEMENT PLAN
I. Background Statement
The federal government has finalized regulations for stormwater management in smaller
communities. These regulations, known as the National Pollutant Discharge Elimination
Systems (NPDES)Phase II rule, ensure compliance with sections of the Clean Water Act
within those communities with populations of 100,000 or fewer residents. In December
2002,the Environmental Protection Agency granted the Arizona Department of
Environmental Quality (ADEQ) primacy (the authority)to manage the NPDES program
within the State.
The Town of Oro Valley(TOV) is a bedroom community of Tucson, AZ and has
approximately 30,000 residents. This fast growing community is supported by residential
and commercial development and industries that do not require an industrial NPDES
permit. Oro Valley is a desert community that has no perennial streams and a few
privately owned impounded water bodies. All waters within TOV are ephemeral streams
that remain for a day or two at most after heavy rains that occur during the summer
monsoon.
II. Environmental Awareness
Protecting the environment is a priority for the community. Development and
construction projects are quite highly regulated. As a matter of routine, Oro Valley has
pre-construction meetings with a developer or contractor prior to initiation of any major
construction projects. (See Attachment I, Preconstruction Meeting Agenda.) The
developer must provide copies of his Stormwater Pollution Prevention Plan (SWPPP) and
Notice of Intent(NOI)to TOV staff for review and approval before a grading permit is
issued by TOV. The Oro Valley Zoning Code Revised Table of Contents (Attachment II)
lists pertinent chapters (Attachments III-IX)that will be used to manage TOV's
Stormwater Management Plan(SWMP). As a requirement of the SWMP, the Grading
Ordinance, Chapter 15-11 will be reviewed, and if necessary, revised to include
enforcement policies and penalties that may be levied for noncompliance with the
ordinance and/or SWPPP. The SWMP further mandates periodic on-site inspections of
construction sites. Methodology for inspections and documentation of results will be
developed during the current NPDES permit period. A Stormwater Ordinance,
Attachment X, has been drafted and will be finalized during the permit period.
During the permit period, chapters of ordinances relevant to the Oro Valley Department
of Public Works, Oro Valley Parks and Recreation Department, and the Oro Valley
Water Utility will also be reviewed with respect to relation to or impact on stormwater
run-off quality, and if necessary, revised to include enforcement policies and penalties.
Town of Oro Valley, Arizona, Stormwater Management Plan, continued
III. Stormwater Management Plan
The Oro Valley Town Council created the Stormwater Utility Commission (SWUC) in
Jul 2001 and appointed members to the SWUC in October of that year. The five (5)
July
Commission members are a representative cross section of the population of the Town.
SWUC has met at least once each month since October 2001. SWUC initially prepared
the organizational documents for the Commission. (See Attachments XI-XIII.) The
SWUC was tasked to 1) Specify best management practices for six(6) minimum control
measures that the Town of Oro Valley would implement to the"maximum extent
practicable" (MEP). 2)Identify measurable goals for the BMPs. 3) Show an
implementation plan of activities or frequencies of activities. 4) Define the entity
responsible for implementation. 5)Ensure that TOV regulates construction activities that
disturb one or more acres. The enclosed list of BMPs, measurable goals, and
implementation schedule with deadlines for the BMPs resulted from these meetings. The
BMPs comply with the AZPDES permit. The BMPs and stormwater and basin
maintenance activities identified in the Oro Valley Town Wide Drainage Study Drainage
Problem Identification and Solution Plan, Attachment XIV, constitutes the Town's
Stormwater Management Plan. SWUC members will meet with appropriate TOV staff at
least annually to review the BMPs. SWUC, with input from staff, as necessary, will
revise the Stormwater Management Plan.
Floodwater and nuisance drainage flows occasionally affect The Town of Oro Valley.
These floodwaters and nuisance drainage flows may pose a hazard to human life as well
as to private and public property. In 2000, the Town Council commissioned a consultant
to conduct a town-wide drainage study. The Oro Valley Town Wide Drainage Study-
Drainage Problem and Solution Plan, Project Number DPW 99/00-10 was completed in
May 2001. The Study identifies several flood and drainage problem areas and provides a
brief description of possible solutions to the identified problem areas. Proposals for
stormwater and basin maintenance impacted by sedimentation and wash-off are included
in the Study. TOV's SWMP incorporates the Study's proposals.
Staff from TOV has the ultimate responsibility to implement and maintain the SWMP.
However, use of volunteers has been incorporated into the program. Programs such as
Adopt-a-Wash will recruit volunteers from the Town's general population. After
appropriate training, these volunteers will assist staff with monitoring washes to identify
points of illicit discharges and dumping, to document such events, and properly collect
samples to quantify and qualify discharges.
IV. Through the Town Council, the Director of the Public Works Department has ultimate
responsibility for implementation, management, and maintenance of the BMPs,
measurable goals, and plan schedule. Mr. William Jansen is the current director. Mr.
Jansen may elect to delegate day-to-day responsibility to other members within the Public
Works Department.

1) Public Information and Outreach on Storm Water Impacts
i) A description of the education plan and outreach activities;
See the attached Town of Oro Valley Schedule of Best Management
Practices, Measurable Goals, and Implementation Plan for Six (6)
Minimum Control Measures.
ii) A description of the methods for disseminating information;
See the attached Town of Oro Valley Schedule of Best Management
Practices, Measurable Goals, and Implementation Plan for Six (6)
Minimum Control Measures.
iii) The target audiences and target pollutants and sources that the applicant
will address in the program, and how they were selected;
See the attached Town of Oro Valley Schedule of Best Management
Practices, Measurable Goals, and Implementation Plan for Six (6)
Minimum Control Measures. Target audiences - homeowners,
construction industry and commercial property owners selected as they
have the most control over potential pollutants in our community.
While pollutants don't appear to be a problem in our community, the
most likely potential pollutants to target are sediment from
construction sites, oil & grease from parking lots, and trash. Because
Oro Valley is a bedroom community to Tucson, there is little industrial
activity. What little industry there is in the Town does not discharge
wastewater to the MS4 or waters of the U.S. Construction activity is
the major industry in the Town. Construction is waning as the Town is
nearly built-out. Barring significant annexation to the north and/or
west, complete build-out is expected within the next 10 years. There is
limited commercial property in the community. Some commercial
properties do have large parking lots. Most of the commercial
property is dedicated to retail, office and apartment space.
