Approval of First Amendment to the Wastewater Services Agreement(O&M)
Veolia Water West Operating Services Inc.
BACKGROUND:
Beginning in 1999 the City has utilized private contractors to provide operation and
maintenance services associated with its Wastewater Treatment Plant (the "WWTP"),
the sanitary sewer collection system, the sanitary storm sewer system, and
administration of various related programs (Sewer Services). The City entered into a
contract with US Filter, subsequently Veolia Water North America Operating Services,
Inc. (Veolia) to provide Sewer Services for an initial term through June 30, 2005.
Various amendments were made during the life of the Agreement.
Most recently, on November 4 2015, City Council approved a new Wastewater Services
Agreement for operation andAmaintenance with Veolia, which commenced on January
1, 2016, for an initial term of 5 years through December 31, 2020, with two 5-year
optional extended terms available at the City's sole discretion.
The City's WWTP has been operating under regulations issued by the California
Regional Water Quality Control Board, Colorado River Basin Region (RWQCB) through
its Waste Discharge Requirements (WDRs) Order No. 93-076, adopted on November
17, 1993.
On September 21, 2017, the RWQCB adopted new regulations for the City's operation
of its WWTP pursuant to Board Order R7-2017-0013 (included as Attachment 1),
which updated the previous Board Order No. 93-076 to incorporate provisions to comply
with current WDRs and to require the City to evaluate and analyze potential impacts on
groundwater caused by the discharge of its treated effluent. The new WDRs require that
the City and its operator take steps to identify problematic waste streams, verify the
suitability of the groundwater monitoring network, and complete an analysis of nitrogen
and total dissolved solids (TDS) in the effluent on the receiving waters.
In addition to the requirement to perform studies on the adequacy of the groundwater
monitoring wells, TDS sources, and Nitrogen, the City is required to develop and
implement a Municipal Industrial Pretreatment Program (MIPP) that will add a new
regulatory scheme whereby the City, through Veolia, will identify commercial and
industrial businesses that have the potential to discharge effluent to the City's sewer
system that require pre-treatment prior to discharge, to eliminate any pollutants from
entering the sewer system and the City's WWTP. The pollutants of concern are related
to TDS (i.e. high levels of salts, chloride, etc.), nitrogen, certain metals, and other
pollutants, and generally are caused by certain businesses that use chemicals or
perform mechanical repairs (i.e. autobody repair shops), or generate waste streams
with high concentration of salts.

Veolia Water West Operating Services Inc.
Implementing the MIPP, and avoiding the discharge of pollutants into the City's sewer
system from certain commercial and industrial businesses that generate polluted
wastewater, is an important objective for the RWQCB, and will help to avoid further
requirements for the City to invest in significantly expensive new treatment technologies
at the WWTP.
Veolia has provided a proposal to develop and implement the MIPP, which includes
tasks that are not covered in the current agreement to provide Sewer Services. The
inclusion of the tasks required to develop and implement the MIPP necessitate an
amendment to the Wastewater Services Agreement No. 6804, which is included as
Attachment 2.
ANALYSIS:
The RWQCB reviewed and updated the City's WDRs in consultation with the City and
Veolia over the last several years. Under the prior Board Order No. 93-076, the
RWQCB regulated the City's discharge of treated effluent to the percolation ponds,
limiting the levels of chloride, fluoride, and sulfates (the main constituents of TDS). On
an annual basis, the City's WWTP was unable to meet the limits imposed by the
RWQCB related to chloride, fluoride and sulfate, due to the fact that the WWTP does
not have treatment technology to eliminate these elements.
Similarly, the prior Board Order No. 93-076 regulated the City's discharge of treated
effluent related to nitrogen levels. On an annual basis, the City's WWTP was unable to
meet the limit imposed by the RWQCB related to nitrogen due to the fact that the City's
WWTP does not have treatment technology to eliminate nitrogen from the effluent.
The fact that the City was not meeting the limits for chloride, fluoride, sulfate, and
nitrogen was not a critical issue for the following two reasons:
1. Through the City's efforts to encourage water conservation, mandated through
Building Code updates and other sustainable efforts, the volume of wastewater
discharged to the WWTP has significantly reduced, from 10 million gallons per day
(mgd) in 1992 to 6 mgd in 2016, a 40% reduction despite the widespread
development throughout the City during the last 25 years;
2. Through the City's cooperative efforts with Desert Water Agency (DWA) to reuse the
City's treated effluent for recycled irrigation purposes prior to discharge to the
percolation ponds, the volume of treated effluent intercepted by DWA and reused
has significantly increased.
The RWQCB was aware of these facts, and also recognized the important cooperative
efforts of the City and DWA to reuse the City's treated effluent prior to discharge to the
percolation ponds, thereby intercepting the volume of wastewater potentially impacting
groundwater. The City and DWA first entered into a cooperative agreement on
03

Approval of First Amendment to the Wastewater Services Agreement(O&M)
Veolia Water West Operating Services Inc.
wastewater reuse and reclamation in 1977, and over the last 40 years have continued
to cooperate on water reclamation which si reflected in the following statistics:
➢ In 1988, the City treated 2.7 billion gallons of sewage, of which 345 million gallons
(or 12.6%) was diverted from the City's percolation ponds to DWA for reclaimed
water reuse.
➢ In 2016, the City treated 2.1 billion gallons of sewage, of which 1.6 billion gallons (or
77%) was diverted from the City's percolation ponds to DWA for reclaimed water
reuse.
Thus, despite the substantial development of residential and commercial properties in
the last 25 years, generating increased sewage Citywide, and increasing reuse of
reclaimed water by DWA, the volume of treated effluent with elevated levels of chloride,
fluoride, sulfate, and nitrogen discharged to the percolation ponds, and ultimately having
the potential to degrade groundwater, has been drastically reduced. Put another way, if
the City was treating the maximum volume capacity of its WWTP of 10.9 mgd, without
any diversion to DWA for reclaimed water reuse (100% discharged to the City's
percolation ponds), Board Order No. 93-076 and the recently adopted Order R7-2017-
0013 allows for discharge of 4 billion gallons annually to the percolation ponds.
However, due to water conservation and DWA's reclaimed water reuse, the actual
volume of treated wastewater discharged to the percolation ponds in 2016 was limited
to 490 million gallons, which is only 12% of the volume the City is otherwise authorized
to discharge.
In its adoption of Order R7-2017-0013, the RWQCB agreed to eliminate the individual
discharge limits for chloride, fluoride, and sulfate on the condition that the City analyze
the potential effects of the discharge of its effluent to groundwater. Specifically, the
RWQCB has required the following:
1. Groundwater Monitoring Network Technical Report and Work Plan,
2. Nitrogen Control Strategy Technical Report,
3. Total Dissolved Solids Source Control Technical Report
The findings from these reports will inform changes that may need to be made at the
WWTP, either in operations, procedures or physical upgrades required to comply with
new limits identified in Order R7-2017-0013. City staff and the RWQCB will work
together to identify any changes in WWTP operations that are required to meet new
limits based on the results of these studies. Any proposed changes to the City's
operations of the WWTP will be administered through Veolia, the WWTP operator, and
any modifications that impact the City's and Veolia's operations will be presented to the
City Council prior to implementation.

Performing the needed studies requires securing services from professional firms with
expertise in these fields. Veolia requested proposals from four firms who specialize in
performing these tasks: Larry Walker and Associates (LWA), Hazen and Sawyer (HAS),
GEI Consultants, and EnviroLogic Resources, Inc.
The following outlines the proposals received by Veolia on behalf of the City:
• Larry Walker and Associates (LWA); Proposal Estimate: $126,640
• Hazen and Sawyer(HAS); Proposal Estimate: $200,000
• GEI and Associates: Declined to submit proposal
• EnviroLogic Resources, Inc.; Proposal Estimate: $191,775
After reviewing the proposals for scope, project understanding, technical expertise, and
comparable experience, it was determined that LWA was the firm best suited to perform
the required studies under Veolia's supervision. The LWA proposal was ranked based
on qualifications, not cost, consistent with selection of a professional services contract.
LWA's proposal included a cost for services with a total of $126,640. Section 7.5 of the
Wastewater Services (O&M) Agreement between the City and Veolia allows for Veolia
to subcontract professional services, subject to a 15% mark-up for administrative and
overhead costs. The total cost for the professional services related to the RWQCB
required studies is $145,636. Veolia's proposal is included as Attachment 3.
ENVIRONMENTAL IMPACT:
Section 21084 of the California Public Resources Code requires Guidelines for
Implementation of the California Environmental Quality Act ("CEQA"). The Guidelines
are required to include a list of classes of projects which have been determined not to
q p J
have a significant effect on the environment and which are exempt from the provisions
9 p
of CEQA. In response to that mandate, the Secretary for Resources identified classes
of projects that do not have a significant effect on the environment, and are declared to
be categorically exempt from the requirement for the preparation of environmental
documents. In accordance with Section 15301 "Existing Facilities," Class 1 projects
consist of the operation, repair, maintenance, permitting, leasing, licensing, or minor
alteration of existing public or private structures, facilities, mechanical equipment, or
topographical features, involving negligible or no expansion of use beyond that existing
at the time of the lead agency's determination. More specifically, Class 1(b) includes the
operation, repair and maintenance of existing facilities of public-owned utilities used to
provide sewerage or other public utility services. Approval of the Wastewater Services
Agreement for operation and maintenance with Veolia Water West Operating Services,
Inc., will authorize Veolia to perform such services required to operate and maintain the
City's WWTP and sanitary sewer collection system and related facilities, and is
therefore considered Categorically Exempt from CEQA.

FISCAL IMPACT:
The current O&M Fee paid to Veolia to provide sewer services to the City is $3,429,483
for calendar year 2017.
Proposed First Amendment
The First Amendment will increase the annually reoccurring O&M Fee by $59,800 for
providing services related to implementing the MIPP, with an additional $10,000 annual
budget for reimbursement of laboratory and analytical costs. This represents an
increase of $69,800 annually, or a 2% increase.
The First Amendment also incorporates a one-time budget of$146,656 for reimbursable
expenses associated with developing the MIPP.
The total cost of the First Amendment is $216,456.
Separately, the City will reimburse Veolia for its direct costs associated with completion
of the various studies required by the RWQCB, not to exceed $145,636.
All costs associated with the Agreement, Amendment No. 1, and the Purchase Order,
are entirely funded by the Wastewater Enterprise Fund (Fund 420). Sufficient funds are
available in Account No. 420-6800-43200.

BOARD ORDER R7-2017-0013
WASTE DISCHARGE REQUIREMENTS
FOR
CITY OF PALM SPRINGS, OWNER
VEOLIA WATER WEST OPERATING SERVICES, INC., OPERATOR
PALM SPRINGS WASTEWATER TREATMENT PLANT
Palm Springs—Riverside County
The California Regional Water Quality Control Board, Colorado River Basin Region (Colorado River
Basin Water Board)finds that:
1. The City of Palm Springs owns a wastewater treatment plant (VW TP or Facility) that
provides sewerage service to the City residents and businesses. The WWTP is operated
by Veolia Water West Operating Services Inc. The City of Palms Springs and Veolia Water
West Operating Services, Inc. are hereby collectively or individually referred to as
Discharger.
2. The Discharger submitted an application and Report of Waste Discharge (ROWD) in June
2013 to update Waste Discharge Requirements (WDRs)for the WWTP to reflect proposed
design modifications to the Facility, which are discussed in Findings 7, 8, 9 and 10.
3. Palm Springs WWTP is at the end of Vella Road, south of E. Mesquite Ave., Palm Springs,
as shown on the Location and Vicinity Map, Attachment A, incorporated herein and made
part of this Order by reference. The Facility is located in the southeast % of Section 19,
Township 4 South, Range 5 East, San Bernardino Baseline and Meridian. The Facility is
assigned the California Integrated Water Quality System (CIWQS) No. CW-247435,
Waste Discharge Identification (WDID) 7A330114012 and GeoTracker Global ID number
WDR100032535.
4. The discharge from the Facility is currently regulated by WDRs Order 93-076, adopted on
November 17, 1993. The City of Palm Springs also owns a wastewater collection system
that is regulated under State Water Resources Control Board General Order 2006-0003-
DWQ, Statewide General Waste Discharge Requirements for Sanitary Sewer Systems.
5. WDRs Order 93-076 must be updated to incorporate design modifications at the Facility and
implement the most current water quality laws and regulations applicable to the discharge.
6. The Facility has been regulated by the Colorado River Basin Water Board since its
construction in 1960. The Colorado River Basin Water Board action, Resolution 63-3, and
subsequent Resolutions and Board Orders contained effluent limitations for sulfate and
chloride. This Board Order removes the effluent limits for chloride, fluoride and sulfate and
introduces a regulatory approach where these analytes will be regulated as constituents of
total dissolved solids (TDS). The Special Provisions of this Board Order require that the
Discharger conduct an investigation to control salinity, and develop and implement a source
control program for mineralized waste discharges into the collection system. After
completion of the investigation, the Discharger will present conclusions and
recommendations for a final TDS effluent limit in a technical report. In addition, the Special
Provisions of this Order require the Discharger to conduct a nitrogen fate and transport study
08
City of Palm Springs Board Order R7-2017-0013
Wastewater Treatment Plant Waste Discharge Requirements
and prepare a technical report to investigate the sources of nitrogen in the discharge and
determine the relationship between the discharge and the levels of nitrogen nitrates found
in the groundwater monitoring network.
Wastewater Treatment Facility and Discharge
7. The Facility is currently designed to treat and discharge up to 10.9 million gallons per day
(MGD) of treated domestic wastewater. Attachment B, incorporated herein and made part
of this Order by reference, shows the Facility's Schematic Flow Diagram. The treatment
system consists of the following processes:
a. Preliminary Treatment: Preliminary treatment includes one automatic bar screen,which
is followed by two aerated grit chambers operating in parallel. Large materials are
removed by the bar screen. Sand and heavy inorganic particles are removed in the
aerated grit chambers. Removed material is collected and disposed of at an approved
solid waste management facility.
b. Primary Treatment: Effluent from the aerated grit chambers enters one of three primary
clarifiers operating in parallel, where solids settle to the bottom of the tank and are
segregated from the effluent. Grease and oils, which float to the surface, are skimmed
off and segregated from the effluent. Sludge solids and grease are then pumped to the
gravity thickeners for further concentration.
c. Secondary Treatment: Secondary treatment includes four trickling filters and six
secondary clarifiers with both systems operating in parallel. Effluent from the primary
clarifiers is combined with recycled trickling filter or secondary effluent for dilution. The
combined flow is then pumped over the trickling filters where the majority of the soluble
organic matter is removed through absorption and utilization by the biological organisms
growing on the trickling filter media. Trickling filter effluent, along with biological
organisms that periodically slough off the media, flows to the secondary clarifiers where
suspended solids are removed before discharge. Solids collected at the secondary
clarifiers are pumped to a gravity thickener. The solids are then transferred to anaerobic
digesters for further treatment.
d. Effluent Disposal: Approximately 25 percent of the final WWTP effluent is disposed of
to one of six unlined evaporation/percolation ponds (totaling 23.3 acres). This Board
Order regulates the discharge to the evaporation/percolation ponds. The effluent
discharged to the evaporation/percolation ponds is rotated from pond to pond on a
frequency that does not exceed 7 days for each pond. Following the use of an
evaporation/percolation pond for disposal of treated wastewater, the Discharger
performs maintenance for sludge control and soil scarification to maximize percolation
and minimize evaporation, which reduces the increase in salinity of the ponded treated
wastewater.
The balance of the effluent from the WWTP (approximately 75 percent) is conveyed
directly via a dedicated treated wastewater pipe to the Desert Water Agency (DWA),
Wastewater Reclamation Plant (WRP) for tertiary treatment. The WRP operated by
DWA is regulated by WDRs Order R7-2014-0008. DWA distributes tertiary-treated
disinfected recycled water for use as landscape and golf course irrigation. Recycled
water use has increased from approximately 2.4 mgd in 1998 to approximately 4.5 mgd
in 2016.
e. Solids Handling: All solids collected in the primary treatment after the grit chambers and
secondary treatment processes are pumped to two gravity thickeners, which are
2 CI 9
City of Palm Springs Board Order R7-2017-0013
Wastewater Treatment Plant Waste Discharge Requirements
operated in parallel. There the solids are settled to increase the total solids
concentration prior to pumping to two anaerobic digesters,which are currently operated
in series but may also be operated in parallel, if necessary. In the anaerobic digesters,
organic solids in the sludge are reduced through the biochemical reactions of biological
organisms. Methane and carbon dioxide are produced as a result of the process. The
methane is disposed of in a gas flare. The digestion process is comprised of primary
and secondary stages. In the primary stage the majority of the organic solids destruction
takes place. In the secondary stage destruction continues and the solids are stored and
concentrated. The solids are then drawn off into one of twenty-six (26) sludge drying
beds where the solids are dried for several weeks. The dry solids concentration of the
sludge in the drying bed can be increased from about 2.5%total solids to over 90%total
solids. A belt filter press was installed in 2002 to allow for increased solids dewatering
capabilities during the cooler winter months,when drying times are longer and the drying
beds can reach capacity. Water that is removed from the sludge in the solids handling
processes is collected and returned to the plant headworks for treatment. Dewatered
solids are stored in an asphalt-lined impoundment area for eventual removal by a
biosolids hauling contractor for legally permitted composting or land application.
f. SCADA System: A Supervisory Control and Data Acquisition(SCADA)system provides
monitoring of plant equipment and processes. The system utilizes a central computer
station, as well as remote Programmable Logic Controllers(PLCs) and panel view units
that allow key equipment and processes to be viewed from various locations throughout
the Facility. Operational trends are monitored and all flow and pond level data are saved
to a permanent archive. The system monitors equipment and sends alarms to operators
if problems are detected.
g. Backup Power: Back-up power is available for all treatment processes.
8. The original WWTP was constructed in 1960. A major expansion of the WWTP to its current
10.9 million MGD capacity was completed in 1983. In consultation with Veolia Water West
Operating Services, Inc., the City of Palm Springs staff prepared a comprehensive Capital
Improvement Plan (CIP) for the WWTP, which addressed on-going maintenance issues at
the WWTP that have resulted from aged mechanical equipment. Many of the WWTP's
treatment units are past their useful life and are in need of replacement. The CIP identified
the need to focus on major capital projects to replace aging equipment and improve
inefficient wastewater treatment processes at the WWTP over a period of 20 years. The
CIP, submitted to and approved by the City Council in 2010, is estimated at $67,000,000.
The CIP assessed all of the major unit processes at the City's WWTP, and recommended
a 20-year program consisting of over 30 projects, some of which may be combined into
single projects for better cost efficiencies.
9. Over the last eight years the City has completed rehabilitation of the two anaerobic
digesters, construction of a new reclaimed water pump station, improvements to the gravity
thickeners, construction of an entirely new electrical system, installation of a new backup
power generator, and installation of a new WWTP perimeter security fence.
10. As part of its CIP, the Discharger advertised an estimated $24.5-million construction project
to upgrade the Facility in late 2016. The project consists of a new influent junction box, a
new headworks including metering structure,two mechanical screens with isolation gates,
a bypass channel with isolation gates, an influent pump station equipped with four vertical
solids-handling turbine pumps, two primary clarifiers, two scum pump stations, two sludge
pump stations, one sludge de-gritting station, replacement weir covers for two existing

13. Annual precipitation in the Palm Springs area averages about 5 inches. Annual
evapotranspiration rate is about 66 inches.
14. An ephemeral stream identified as the Tahquitz Creek, a Water of the United States, is
adjacent to the Facility immediately to the south of a flood control levee maintained by the
Riverside County Flood Control District.
15. A series of groundwater wells supply domestic water to the City. Regional groundwater flow
in the area is to the southeast. The average Total Dissolved Solids (TDS) concentration of
the municipal water supply is approximately 350 mg/L.

of the discharge. Attachment C, incorporated herein and made part of this Order by
reference, shows the location of the monitoring wells. Groundwater monitoring samples are
collected from the three wells on a quarterly basis. Wells 1 and 2 are located downgradient
and Well 3 is upgradient of the evaporation/percolation ponds. A review of the groundwater
monitoring data, contained in the table below, indicates that Nitrate, Total Nitrogen, Sulfate
and Chloride, show increased concentrations in the downgradient monitoring wells.
Groundwater monitoring data from November 2011 through October 2016 show the
following average water quality characteristics for groundwater in the vicinity of the
discharge:

18. There are two shallow groundwater production wells downgradient of the
evaporation/percolation ponds. The wells are operated by DWA for the purpose of
supplementing recycled water when demand is high.
19. The site is located in a seismically active desert region.
Basin Plan, Beneficial Uses, and Regulatory Considerations
20. The Water Quality Control Plan for the Colorado River Basin (Basin Plan), which was
adopted on November 17, 1993, and amended on March 7, 2017, designates beneficial
uses, establishes water quality objectives, and contains implementation programs and
policies to achieve those objectives for all waters addressed through the plan (including
amendments adopted by the Colorado River Basin Water Board to date). Pursuant to
section 13263(a)of the California Water Code(CWC),waste discharge requirements must
implement the Basin Plan and take into consideration the beneficial uses to be protected,
the water quality objectives reasonably required for that purpose, other waste discharges,
the need to prevent nuisance, and the provisions of Water Code section 13241.
21. The discharge is within the Coachella Hydrologic Subunit, and the Basin Plan designated
beneficial uses for groundwater include:
a. Municipal supply(MUN),
b. Industrial supply(IND), and
c. Agricultural supply(AGR)
22. These WDRs implement numeric and narrative water quality objectives for ground and
surface waters established by the Basin Plan. The numeric objectives for groundwater
designated for municipal and domestic supply are the Maximum Contaminant Levels
(MCLs), and bacteriological limits specified in section 64421 et seq. of Title 22 of the CCR.
5 12
City of Palm Springs Board Order R7-2017-0013
Wastewater Treatment Plant Waste Discharge Requirements
The Basin Plan states that:
a. Groundwater for use as domestic or municipal water supply (MUN) must not contain
taste or odor-producing substances in concentrations that adversely affect beneficial
uses as a result of human activity.
b. Groundwater designated for use as domestic or municipal supply (MUN), the
concentration of coliform organisms shall not exceed the limits specified in Section
64426.1 of Title 22 of the CCR.
23. The Basin Plan, Chapter 3 Water Quality Objectives, Section IV Groundwater Objectives,
states that the goal of the Colorado River Basin Water Board is to maintain the existing
water quality of all non-degraded ground water basins. Generally, ground water that is
pumped returns to the basin after use with an increase in mineral concentrations such as
TDS, nitrate etc., that are picked up by water during its use. Under these circumstances,
the Colorado River Basin Water Board's objective is to minimize the quantities of
contaminants reaching any ground water basin. This could be achieved by establishing
management practices for major discharges to land. The Effluent Limitations and Special
Provisions of this Order require the Discharger to develop management practices that
effectively minimize the quantities of contaminants reaching the groundwater in the area of
the evaporation/percolation ponds.
24. It is the policy of the State of California that every human being has the right to safe, clean,
affordable, and accessible water adequate for human consumption, cooking, and sanitary
purposes. This Order promotes that policy by requiring discharges to meet maximum
contaminant levels designed to protect human health and ensure that water is safe for
domestic use.
25. Section 13267 of the CWC authorizes the Colorado River Basin Water Board to require
technical and monitoring reports. The Monitoring and Reporting Program (MRP)
establishes monitoring and reporting requirements to implement state requirements and
demonstrate compliance with the Order. The State Water Board's electronic database,
GeoTracker Information Systems facilitates the submittal and review of facility
correspondence, Discharger requests and monitoring and reporting data.
26. This Order establishes WDRs pursuant to Division 7, Chapter 4, Article 4, of the CWC (for
discharges that are not subject to regulation under section 402 of the Clean Water Act (33
U.S.C. Section 1342).
27. Pursuant to CWC section 13263(g), the discharge of waste is a privilege, not a right, and
adoption of this Order does not create a vested right to continue the discharge.
28. The discharge as authorized by this Order, and treatment and storage facilities associated
with discharges of treated municipal wastewater, except for discharges of residual sludge
and solid waste, are exempt from the requirements of the Consolidated Regulations for
Treatment, Storage, Processing, or Disposal of Solid Waste, as set forth in Title 27, CCR,
Division 2, Subdivision 1 (Title 27), commencing with section 20005. This exemption is
based on section 20090(a) of Title 27, which states in relevant part that discharges of
domestic sewage or treated effluent are exempt provided that such discharges are regulated
by WDRs, or for which WDRs have been waived, and which are consistent with applicable
water quality objectives, and treatment or storage facilities associated with municipal
wastewater treatment plants, provided that residual sludges or solid waste from wastewater
treatment facilities shall be discharged only in accordance with the applicable Title 27
6 � 3
City of Palm Springs Board Order R7-2017-0013
Wastewater Treatment Plant Waste Discharge Requirements
provisions. The discharge is treated domestic wastewater. This Order regulates the
discharge in a manner consistent with applicable surface and ground water quality
objectives, and residual sludges or solid waste from the Facility will be managed pursuant
to Title 27. All of these Title 27 exemptions have been met.
29. This Order regulates the discharge of wastes to the onsite evaporation/percolation ponds
and allows the Discharger to distribute secondary treated wastewater to DWA for
additional treatment and eventual reuse. The storage and conveyance facilities associated
with the distribution of secondary treated wastewater to DWA are exempt from the
requirements of Title 27, based on section 20090(h). The Discharger's compliance with
this Order results in meeting the applicable Title 27 provisions.
30. State policy promotes the use of recycled water to the maximum extent in order to
supplement existing surface and ground water supplies to help meet water needs (CWC
sections 13510-13512). One of the primary conditions on the use of recycled water is
protection of public health (CWC sections 13521, 13522, 13550(a)(3)).
31. The portion of the discharge authorized by this Order that is conveyed to DWA for treatment
and reclamation is consistent with the State Water Board's Recycled Water Policy.
32. Section 403.8(a) of Part 40 of the Federal Code of Regulations requires any publicly
owned treatment works (POTW) with a total design flow greater than five (5.0) MGD to
develop a pretreatment program if it receives pollutants from industrial users that pass
through or interfere with POTW operation or if it has industrial users subject to federal
categorical Pretreatment Standards.
33. Section 2233 of Title 23 of the CCR requires a pretreatment condition to be included in
non-NPDES WDRs for all POTWs. The Discharger's ROWD does not identify industrial
discharges into its collection system. The Discharger will be required to provide a routine
assessment of its industrial dischargers in the annual Self-Monitoring Reports (SMRs) to
determine whether the Discharger is a pretreatment program becomes necessary.
State Anti-Degradation Policy
34. State Water Board Resolution 68-16, Policy with Respect to Maintaining High Quality
Waters of the State, (Resolution 68-16) states:
"Whenever the existing quality of water is better than the quality established in policies as
of the date on which such policies become effective, such existing high quality will be
maintained until it has been demonstrated to the State that any change will be consistent
with maximum benefit to the people of the State, will not unreasonably affect present and
anticipated beneficial use of such water and will not result in water quality less than that
prescribed in the policies."
If an activity may result in degradation to high quality waters, Resolution 68-16 further
states:
"Any activity which produces or may produce a waste or increased volume or concentration
of waste and which discharges or proposes to discharge to existing high quality waters will
be required to meet waste discharge requirements which will result in the best practicable
treatment or control (BPTC) of the discharge necessary to assure that (a) a pollution or
7 14
City of Palm Springs Board Order R7-2017-0013
Wastewater Treatment Plant Waste Discharge Requirements
nuisance will not occur and (b)the highest water quality consistent with maximum benefit to
the people of the State will be maintained."
35. The Colorado River Basin Water Board has determined that some degradation of
groundwater from the discharge to the evaporation/percolation ponds is consistent with
Resolution 68-16, provided that the degradation:
a. Is confined to a reasonable area;
b. Is minimized by means of full implementation, regular maintenance, and optimal
operation of BPTC measures;
c. Is limited to waste constituents typically encountered in domestic wastewater; and
d. Does not result in the loss of any beneficial use as prescribed in the applicable basin
plan, or violation of any water quality objective.
36. Constituents in the WWTP effluent that have the potential to degrade groundwater include
nitrogen, coliforms(pathogen-indicator organisms), TDS, and chloride and sulfate. Each of
these constituents is discussed below:
a. Nitrogen. The Discharger's SMRs from November 2011 through October 2016 show
a range of 8.8 to 26.8 mg/L with an average 16.5 mg/L for total nitrogen in the effluent.
Upgradient monitoring well MW3 shows nitrate as nitrogen concentrations averaging
7.8 mg/L and total nitrogen averaging 8.5 mg/L. Downgradient monitoring wells show
nitrate as nitrogen concentrations averaging 9.1 mg/L (total nitrogen averaging 9.9
mg/L) in well MW1 and 16.0 mg/L (total nitrogen averaging 18.4) in well MW2. Well
MW2 nitrate data indicate that the discharge of treated wastewater may be impacting
groundwater at a rate or in concentrations causing groundwater to exceed the Primary
MCL prescribed in Title 22, CCR section 64431.
Using recycled water for golf course and landscape irrigation has mitigated the rate of
increase and extent of the elevated nitrogen concentrations in groundwater in the area
of the evaporation/percolation ponds. The Discharger currently conveys approximately
75 percent of the secondary treated wastewater to DWA for further treatment and
distribution as recycled water. Additionally, DWA has installed two shallow
groundwater wells downgradient of the evaporation/percolation ponds to supplement
reclaim water supplies. Groundwater extraction from these two wells has further
mitigated the amount of nitrogen in the aquifer.
Nevertheless, monitoring data of the groundwater wells in the vicinity of the WWTP
indicate that the effluent may be causing or contributing to nitrogen/nitrate impairment in
the groundwater in the area of the evaporation/percolation ponds. Even with reductions
in nitrogen loading due to increased water recycling, continuation of the existing
treatment and evaporation/percolation pond disposal practices may pose a threat to the
beneficial use of groundwater. The Colorado River Basin Water Board recognizes that
immediate compliance with groundwater objectives for nitrogen may not be achievable
due to historic land use practices. This Order introduces a groundwater limitation for
nitrogen. Special Provisions section EA of this Order also requires that the Discharger
conduct a comprehensive investigation of the sources of nitrogen and the fate of
transport in the groundwater The Discharger is also required to evaluate the feasibility
of achieving a 10 mg/L total nitrogen effluent limit. The results of this investigation may
require the Discharger to: (1) develop and implement a nitrogen source control program,
(2) enhanced management practices, and/or (3) install advanced treatment systems to
reduce or eliminate nitrogen discharges to groundwater.

City of Palm Springs Board Order R7-2017-0013
Wastewater Treatment Plant Waste Discharge Requirements
b. Coliforms. Secondary treatment reduces fecal coliform densities by 90 to 99%; the
remaining organisms in effluent are still 105 to 106 MPN/100 ml (U. S. Environmental
Protection Agency, Design Manual, Municipal Wastewater Disinfection; October 1986).
Given the depth to groundwater, which is approximately 190 feet in the vicinity of the
WWTP, it is not likely that pathogen-indicator bacteria will reach groundwater in excess
of that prescribed in Title 22, CCR, due to significant attenuation and removal in the soils
in the vadose zone. To verify no degradation due to pathogen-indicator organisms is
occurring, this Board Order adds quarterly total coliform and E. coli monitoring in the
groundwater monitoring wells.
c. TDS. During the period of November 2011 through October 2016, the Discharger's
SMRs show that effluent from the WWTP had a TDS range of 430 to 700 mg/L with an
average of 552 mg/L. Under Board Order, 93-076, TDS was measured based on the
incremental addition of TDS above that of the community water supply. Domestic water
supply to the community showed an average TDS concentration of about 350 mg/L from
2011 to 2015. The average TDS increase in the effluent for this facility over the domestic
water supply for the same time period was about 175 mg/L. Salinity, measured as TDS
of the groundwater in the vicinity of the WWTP ponds, ranges from 667 mg/L at Well 3
(upgradient) to 694 mg/L at Well 2 (downgradient). Title 22 of the CCR lists a
Recommended Secondary MCL for TDS of 500 mg/L, an Upper Level of 1000 mg/L and
a Short Term Level of 1500 mg/L. To minimize further degradation of the groundwater
from TDS, this Order establishes restrictions on the WWTP intended to minimize TDS
discharges and to prevent long-term impacts to beneficial uses. This Order introduces
an interim effluent limitation for TDS based on based on the 99t' percentile of the of the
WWTP effluent TDS data over the previous three years. Because the interim effluent
limit exceeds the recommended secondary MCL, Special Provisions 4 of this Order also
requires that the Discharger conduct a comprehensive investigation of the sources of
salinity to the collection system and to develop and implement a source control program
for salts and mineralized wastes. The results of this investigation will be used develop a
final TDS effluent limit.
d. Chloride and Sulfate. The Discharger's monitoring data and June 26, 2013 ROWD
show an increase in chloride and sulfate concentrations in the effluent has occurred over
the past 20 years. Recent effluent monitoring for chloride and sulfate show a maximum
concentration of 117 and 132 mg/L, respectively. Chloride and sulfate are present in the
water supply. The concentration of these inorganic constituent increases from
contributions of municipal wastewater and water softening brines. One of the causes for
the increased concentrations has likely been water conservation measures in the
community that have significantly reduced influent flow to the WWTP. The quantity of
wastewater treated has declined from about 8.8 million gallons per day (MGD) in 1993
to about 5.9 MGD in 2016. Board Order 93-076 contained effluent limitations of 70 mg/L
for chloride and 90 and mg/L for sulfate. However, Title 22 of the CCR lists a
Recommended Secondary MCL for both chloride and sulfate of 250 mg/L, an Upper
Level of 500 mg/L and a Short Term Level of 600 mg/L. This Order replaces the
individual effluent limitations for chloride and sulfate with an interim TDS effluent limit.
The TDS source control study and program, described above, will be used to develop a
final TDS effluent limit consistent with water quality and public health goals. The TDS
effluent limit is expected to provide the necessary protection to groundwater beneficial
use, while giving the Discharger the flexibility to continue and expand water conservation
efforts.

Wastewater Treatment Plant Waste Discharge Requirements
37. The discharge of wastewater from the WWTP, as permitted herein, reflects BPTC. The
controls assure the discharge does not create a condition of pollution or nuisance, and
that the highest water quality consistent with maximum benefit to the people of the State
will be maintained which is consistent with the
anti-degradation provisions of Resolution
9
68-16. The WWTP incorporates:
a. Technology for secondary treated domestic wastewater;
b. Solids handling facilities;
c. An operation and maintenance manual;
d. A City ordinance that is comprised of a comprehensive set of rules and regulations
governing the design, construction, maintenance and use of public and private sewer
facilities within City jurisdictional limits;
e. A network of groundwater monitoring wells;
f. Staffing to assure proper operation and maintenance; and
g. A standby emergency power generator of sufficient size to operate the treatment plant
and ancillary equipment during periods of loss of commercial power.
Storm Water
38. Federal regulations for storm water discharges were promulgated by the U.S. Environmental
Protection Agency on November 16, 1990, (40 CFR Parts 122, 123, and 124)to implement
the Clean Water Act's storm water program set forth in Clean Water Act section 402(p) (33
U.S.C. section 1342(p).). In relevant part, the regulations require specific categories of
facilities that discharge storm water associated with industrial activity to"waters of the United
States" to obtain NPDES permits and to require control of such pollutant discharges using
Best Available Technology Economically Achievable(BAT)and Best Conventional Pollutant
Control Technology(BCT)to prevent and reduce pollutants and any more stringent controls
necessary to meet water quality standards.
39. The State Water Board adopted Water Quality Order 2014-0057-DWQ (NPDES No.
CAS000001), General Permit for Storm Water Discharges Associated with Industrial
Activities (Industrial General Permit) on July 1, 2015. Facilities used in the storage,
treatment, recycling, and reclamation of municipal or domestic sewage, including land
dedicated to the disposal of sewage sludge, that are within the confines of the facility, with
a design flow of one million gallons per day or more, or required to have an approved
pretreatment program under 40 CFR Part 403, are required to enroll under the Industrial
General Permit unless there is no discharge of industrial storm water to waters of the U. S..
There are no storm water discharges from the WWTP to waters of the U. S. because all
storm water generated at the facility is directed to the evaporation/percolation ponds, and
does not leave the boundaries of the WWTP. Therefore, the Discharger is not required to
enroll under the Industrial General Permit.
CEQA and Public Participation
40. In accordance with the California Environmental Quality Act (CEQA) (California Public
Resources Code Section 21000 et seq.) and implementing Guidelines (California Code of
Regulations, Title 14, Section 15000 et seq.), The City of Palm Springs(City), acting as the
Lead Agency, prepared a Mitigated Negative Declaration(MND)for the City of Palm Springs
Wastewater Treatment Plant Headworks and Clarifier Upgrade Project(SCH2014041060).

Wastewater Treatment Plant Waste Discharge Requirements
The draft MND was circulated for a mandatory 30-day public commenting period. Based on
the MND, the City determined that although the proposed project could have a significant
effect on the environment, the City explained in the MND that it would avoid the effects or
mitigate the effects to a point where no significant effect on the environment would occur.
On June 18, 2014, the City approved the MND and on June 25, 2014, filed a Notice of
Determination (NOD)with the Clerk of the Board, County of Riverside. The Colorado River
Basin Water Board is a responsible agency under CEQA (Public Resources Code, §
21167.3). The Colorado River Basin Water Board considered the findings of the MND and
concludes that compliance with these waste discharge requirements will prevent any
significant adverse impacts to water quality.
41. The Colorado River Basin Water Board has notified the Discharger and all known interested
agencies and persons of its intent to draft WDRs for this discharge, and has provided them
with an opportunity for a public meeting and an opportunity to submit comments.

City of Palm Springs,
Industrial Pretreatment Program Development

VP of Operations Thomas Garcia City Engineer
Veolia North America City of Palm Springs, CA

Palm Springs, CA
Introduction
Veolia North America, West LLC (Veolia) would like to offer the following proposal for consideration to
develop an industrial pretreatment program. It is recommended that the City of Palm Springs (City)
develop a city-wide industrial pretreatment program that follows the EPA model sewer use ordinance and
pretreatment program guidelines. This will provide a proven program that is both defensible in the
community and court system, in the event that the City is required to take legal action against industrial
user that discharges to the wastewater collection system.
The following is a breakdown of the development process based on the core components of the EPA
recommended industrial pretreatment programs (source control program). The core components are
required to make the program effective. A Fats, Oils, and Grease (FOG) program has already been
developed and implemented by the City and will be combined with this program to create a
comprehensive Industrial Pretreatment program.
I. Core Program Components:
A. User Survey
The User Survey consists of several different searches to identify those businesses that have the
potential to impact the treatment plant or the sewer collection system. These surveys usually
include a review of the following:
• City Utility Billing Records for Water Consumption (Can the City get this info from DWA?)
• New Business Listing by Establishment Date on City web site
• Internet Search
• Street Surveys
• Locate and Mail Survey of Identified Potential Industrial Users
• Review Survey's and Conduct Initial Inspection
• Development of Final User List
44

Industrial Pretreatment Program Development Proposal September 26, 2017
The end product is a set of potential commercial and industrial user lists, identifying those
businesses that may be required to comply with the proposed industrial pretreatment program
rules. Further details are provided in the attached Scope of Project Deliverables document.
B. Existing Regulations, Sewer Service Conditions
This component of the development process is to establish the existing conditions and to evaluate
existing sewer use ordinance and treatment plant conditions to determine if they are adequate or if
there is a need to modify the sewer use ordinance or develop a new document. This usually
includes the following:
• Treatment Plant Influent/Effluent/Sludge Pollutant Loadings
• Treatment Plant Flows and Sludge Production Rates
• Treatment Plant WDR Permits Review
• Review of Existing Industrial User Permits, Agreements, or Contracts (DWA)
• Review of the Existing Sewer Use Ordinance
• Determine Known/Historical Problems in the Collection System and Treatment Plant due to
Industrial User Contribution
The review of the existing city ordinances and intergovernmental agreements will be conducted
concurrently during this phase of the process.
C. Local Limits Development
This component establishes the industrial discharge limits for all pollutants of concern, such as, oil
& grease, inorganic pollutants, heavy metals, and toxic organic compounds. The final result of this
activity is the documentation of the local limits, creating an explanation of the decisions and the
basis for each pollutant for which local limits are developed. These local limits will be adopted into
the sewer use ordinance by the City Council. The EPA recommended methodology will be used to
develop these technically based local limits. The EPA has established fifteen national Pollutants of
Concern (POC) typically discharged to wastewater treatment plants, and has mandated the EPA
Approved Pretreatment Programs to establish technically based local limits for these pollutants.
Pollutants regulated by the sludge disposal rules for the disposal practices used by the City are
also candidates as pollutants of concern. Priority pollutants that have been detected at
concentrations of 0.1 milligrams per liter (mg/L), or more, in the wastewater treatment plant
influent during previous sampling events should also be included as pollutants of concern.
D. Sewer Use Ordinance
Review of the existing sewer use ordinance is necessary as the existing sewer use ordinance may
not be comprehensive enough for the protection of workers, operation of the wastewater collection
system, compliant with the latest EPA regulations, and treatment plant for effective regulation of
industrial discharges. Veolia has developed and submitted a draft Sewer Use Ordinance for the
City's review. This draft will be updated as we move through the Industrial Pretreatment Program
development process and establish Technically Based Local Limits, etc. This process includes
formatting to the typical ordinance format used by the City; working through the ordinance
conditions and terms, with the City Attorney; providing all required referencing within the
ordinance; and responding to any comments from the City Council, staff, and general public.

Industrial Pretreatment Program Development Proposal September 26, 2017
E. Enforcement Response Plan
The Enforcement Response Plan is a written plan that is used by the City to conduct enforcement
actions against industrial users not complying with the terms and conditions of the sewer use
ordinance and industrial pretreatment program, and discharge permits issued to the users. The
purpose of this document is to provide uniform and consistent enforcement of the sewer use
codes. This becomes critical in the event the City must take a legal action against an industrial
user. The proposed Enforcement Response Plan will be based on the EPA Guidance for the
development of Enforcement Response Plans. This plan will also contain samples of enforcement
documents, such as, Notices of Violation, Administrative Orders, Administrative Fee/Fine
Assessments, Service Termination Orders, and Consent Orders.
F. Implementation Management Procedures
The Implementation Management Procedures constitute the Standard Operating Procedures used
to implement the Industrial Pretreatment Program. These procedures identify the persons involved
in the activity, the authority to conduct the activity, the actions to be taken, and references for
further support of the activity. Included in these procedures are samples of all forms used in the
program. The purpose of implementation management procedures is to provide the City with
sufficient guidance to carry out the requirements of the sewer use ordinance in a uniform and
consistent manner to all users of the city wastewater collection system. The EPA does not provide
guidance on the development of these protocols, but has provided guidance through multiple
guidance manuals for the many different activities under the industrial pretreatment rules. Veolia
has developed these implementation management procedures over the past 13 years and has
implemented them at many Veolia projects, in many different states, and different EPA Regions.
These implementation management procedures have been reviewed and audited by the EPA and
State regulatory agencies and found to be in compliance with recommendations for these
procedures. These procedures are not generic and must be modified to meet the local conditions
and the local sewer use ordinances, enforcement response plan, including appropriate references
to local ordinance provisions and state regulations.
G. Issue Industrial User Permits
With any changes to the sewer use ordinance, the City will be required to issue discharge permits
to the existing industrial users and new permits to those identified in the Industrial Waste Survey
development process. Veolia recommends the use of Industrial User permits recommended by the
EPA, following the EPA Guidance for industrial wastewater discharge permits. Sample permits will
be included in the implementation management procedures.
H. Industrial Pretreatment Program Submission to CRWQCB
WDR Permit Order No. 93-076 issued November 17, 1993 requires the investigation for the need
for an Industrial Pretreatment Program following the location and characterization of pollutants
from identified industrial users. This requires the preparation of program documents and
submission to the California Regional Water Quality Control Board for approval.

Industrial Pretreatment Program Development Proposal September 26, 2017
I. Public Outreach and Education
Send a general sewer use information mailer to 26,000 sewer users ("This is Not a Trash Can").
Purchase tri-fold brochures that have the same type of information to set on the engineering
counter, information area at entrance to City Hall, include in the sewer connection permit packet,
participation in community activities, etc.
II. O&M Costs to Implement this Program
A. Industrial Pretreatment Program
The initial implementation of the program is very time consuming. The components of the
industrial pretreatment program need to be implemented immediately for the program to be
developed properly to meet the goals and objectives. Industries identified as significant industrial
users (SIU) need to be permitted first under the program. Each SIU will require onsite training on
how to conduct and report self-monitoring. The pretreatment coordinator or program manager
needs to be trained on how to conduct SIU inspections and sampling on behalf of the City and
how to evaluate self-monitoring reports for compliance. The City also has responsibilities in the
implementation of the program, most of which includes enforcement response procedures.
The resources to meet the demands of the enforcement actions are un-predictable. This is
assuming that there are only one or two SIUs that require discharge permits and routine inspection
and sample monitoring. If the number of SIUs is low, a local commercial laboratory is often used to
collect and analyze samples; therefore the labor demands for City monitoring program will be
reduced.
In addition, the City would have language in the new sewer use ordinance, allowing them to
assess pretreatment cost recovery fees. These fees are typically assessed to recover the costs
associated with the preparation of SIU discharge permits, city inspections, city sampling, and other
activities associated with the implementation of the industrial pretreatment program. This is a
common practice and often expected by industrial users that have production facilities located in
different cities across the nation. Therefore, it is anticipated that the City of Palm Springs will have
the ability to recover the routine operational costs associated with the industrial pretreatment
program.
The Veolia proposal fee structure is based upon a Time & Material (T&M) Fee for the
development of the Palm Springs industrial pretreatment program. Attachment B provides a
breakout of the hourly rate for each person involved with the program development as well as
estimated non-labor costs. Labor and non-labor costs shall include a 15% overhead on the cost
incurred.
Veolia's price to provide all of the services described is broken out as follows:
• Labor costs (cost + 15%) for Industrial Pretreatment Program development is estimated to
be approximately $49,306
• Capital costs (cost + 15%) for required equipment is estimated to be approximately
$96,350.
4?

Industrial Pretreatment Program Development Proposal September 26, 2017
• Total IPP Development cost is estimated to be $145,656.
B. Typical Pretreatment Program Operational Costs
Once the pretreatment program begins to regulate more than two significant industrial users, a full
time pretreatment coordinator is usually required. A single person, with occasional assistance from
a commercial laboratory or treatment plant operators, can usually regulate as many as ten (10)
significant industrial users. Programs of this size usually run an annual budget of $80,000 to
$110,000 including salary, but not including analytical costs, which are usually passed on to the
industrial users in the cost recovery program.
City of Palm Springs Industrial Pretreatment Program Operational Costs - Approximately $69,800
Annually
The implementation of the industrial pretreatment program for 2017 is based on using one half-
time person to coordinate and implement the program. This is proposed as long as there are
fewer than 10 IU's in the program. However, the pretreatment coordinator is proposed to be a
full-time positon.
Veolia is pleased to provide you with this proposal and looks forward to discussing its details with you.
Should you have any questions concerning its content or require additional information, feel free to call
me at 310-863-4749 or Doug Loar at 760-459-6395.
If this Agreement is satisfactory, please sign the enclosed copy of this letter in the space provided, and
return it to VNA.

Subject: SCOPE OF WORK,SCHEDULE AND COST ESTIMATE FOR WDR PERMIT SPECIAL STUDIES
Dear Mr.Garcia:
Larry Walker Associates (LWA) is pleased to present this proposal to provide consulting services to assist
the City with completion of three Special Provisions Studies described in the California Regional Water
Quality Control Board, Colorado River Basin Region's Draft Waste Discharge Requirements (Board Order
117-2017-0013,WDR).
The Special Provisions described in Section E.of the Order include:
• E.1 Groundwater Monitoring Network Technical Report and Work Plan
• E.3 Nitrogen Control Strategy Technical Report: Fate and Transport Investigation, and Effluent
Limit Feasibility Study
• E.4 TDS Source Control Program Technical Report
1.0 Scope of Work
Task 1. Groundwater Monitoring Network Technical Report and Work Plan
The WDR is requiring that the City prepare a Technical Report on the adequacy of the existing
groundwater monitoring network. LWA will develop a Technical Report that includes the following:
1. Description of the current condition of the groundwater monitoring network and evaluation
for whether this network adequately monitors the effects of the discharge from the disposal
ponds on groundwater;
2. Analysis of the groundwater data collected from the existing groundwater monitoring wells.
This analysis shall include maps showing the direction of flow and identification of
upgradient and downgradient monitoring wells;and
3. Statistical analysis for constituents of concern (TDS and its major ions)for the upgradient
and downgradient wells, based on the groundwater data collected to date.

Proposal Provided to: �,-
Larry Walker Associates, Inc. oil
City of Palm Springs -),� �f
CAUFORNIA
Like no place else:'
LWA will evaluate the current conditions and adequacy of the groundwater monitoring network
according to the following subtasks.
Review of Existing Information
LWA will review the data and conclusions from existing monitoring data,technical reports, and previous
investigations which provide information pertaining to the current groundwater monitoring network.
LWA will coordinate with Veolia and City staff to obtain any additional information necessary to
complete the evaluation beyond what is provided in existing technical reports. Anticipated additional
information may include but is not limited to well logs,well construction information, and effluent or
groundwater well monitoring data. Due to the limited number of wells in the monitoring network, LWA
will also gather and review any nearby groundwater data maintained in public databases by the State
Water Quality Control Board, United States Geological Survey,and the California Department of Water
Resources.
Groundwater Monitoring Network Evaluation
Based on information reviewed above, LWA will evaluate the current groundwater monitoring network
with a focus on determining:
• Direction of groundwater flow and identification of upgradient and downgradient monitoring
wells';
• Groundwater quality and groundwater quality trends in downgradient and upgradient
monitoring wells
• Effectiveness and reliability of existing compliance wells to represent downgradient
groundwater quality;
• Effectiveness and reliability of existing background wells to represent upgradient water quality;
and
• Overall adequacy of the existing monitoring network and recommendations. .
Groundwater Monitoring Network Summary Technical Report
LWA will prepare a Groundwater Monitoring Network Summary Technical Report based on data
obtained and evaluated. The Report will specifically address the items noted in the WDR and provide
recommendations regarding any changes or additions to the monitoring networks, if necessary.
If the Technical Report indicates that repairs or additional monitoring wells are necessary, LWA will
prepare a work plan to submit to the Regional Water Board.This work plan will include a description of
proposed changes to the monitoring network(such as monitoring locations,frequency, sampling
protocols, or quality assurance/quality control)and a time schedule for these changes that is as short as
practicable based on the issues identified in the Technical Report.
Task 1 Deliverables:
1 The degree of accuracy when analyzing groundwater flow direction and identifying upgradient and downgradient
wells is contingent upon the amount of groundwater information locally available.

Draft Technical Report February 21, 2018
Final Technical Report March 21,2018
Draft Work Plan (if necessary) 3 months from EO approval of Technical Report
Final Work Plan (if necessary) 4 months from EO approval of Technical Report
The schedule and budget does not include monitoring well design and construction and testing of the
new wells. Should new wells be necessary, a monitoring well installation workplan and well
construction would be conducted in conjunction with another firm. It is estimated that well completion
and monitoring to determine that wells are representative of groundwater quality would take
approximately 2 years from EO approval of the Final Work Plan for Monitoring Network Changes.
Task 2. Nitrogen Control Strategy Technical Report
The WDR is requiring that after determining the groundwater monitoring network is sufficient,the City
shall prepare a Technical Report that includes a work plan and time schedule to evaluate the impact of
the discharge on nitrogen levels in groundwater. LWA will prepare this Technical Report to include the
following:
1. Determination of whether wastewater discharged to the evaporation/percolation ponds is
causing nitrogen impairment to groundwater;
2. Determination of the feasibility of achieving a 10 mg/L total nitrogen effluent limit;and
3. Plan to ensure the limit does not cause exceedance of the nitrogen receiving water limitation.
The Technical Report will be comprised of two main pieces: a fate and transport investigation and an
effluent feasibility study.
Fate and Transport
For the fate and transport investigation, LWA will include:
• An evaluation of nitrogen removal technology;
• Characterization for total nitrogen and nitrates of the wastewater discharged to the
evaporation/percolation ponds and in the receiving groundwater; and
• Evaluation of the impact of the wastewater discharged on the groundwater in the vicinity of
the percolation ponds with respect to nitrogen concentrations.A spreadsheet mixing model
will be used to estimate the distance from the pond at which the groundwater limit can be
met. Impacts will be evaluated with respect to concentration and with respect to total load
of nitrogen discharged. This will help to account for reduced loads discharged to the

percolation pond when effluent is diverted to Desert Water Agency.
Feasibility
For the effluent feasibility study, LWA will include discussion of the practicability of achieving a 10 mg/L
total nitrogen effluent limit, including projected costs and potential sewer rate increases. LWA will
evaluate alternative methods of treatment,optimization of existing treatment processes and other
management strategies(e.g., using high nitrogen water for irrigation)that are available and may be
implemented to achieve a 10 mg/L total nitrogen effluent limit.The alternative analysis will include the
costs of the alternatives, expressed in dollars per ton,of nitrogen removed from the discharge.
Technical Report
LWA will use the information prepared in the Fate and Transport and Feasibility sections to compile a
Technical Report.This Technical Report will include the findings, recommendations and conclusions as
well as a work plan and schedule for facility or operational improvements to achieve needed nitrogen
reductions and comply with the effluent and groundwater quality limits.
Task 2 Deliverables:
• Draft and Final Nitrogen Control Strategy Technical Report
• Draft and Final Work Plan for Facility Improvements
Task 2 Schedule:
Deliverable Date
Draft Technical Report 5 months after groundwater monitoring network
determined to be adequate
Final Technical Report 6 months after groundwater monitoring network
determined to be adequate

Final Work Plan 2 months from completion of Control Study
The schedule for completing the Technical Report is based on nitrogen data being readily available.
Should additional monitoring be necessary,the schedule may need to be revised.
In addition,the budget and schedule assume that the WDR is revised as requested and that the
requirement to provide a "description of soil conditions in the vadose zone,through the saturated zone,
and the effect that the soils have on the fate and transport of nitrogen species(converting nitrogen
species of nitrate/nitrite,etc.)" is removed from this study's requirements.

Like no piece else"
The WDR is requiring that the City prepare a Technical Report that includes a work plan and time
schedule to develop and implement a TDS Source Control Program. LWA will work with Veolia and City
staff to review existing information and determine what additional information and data is needed to
quantify salinity sources. Specifically, LWA will work with staff to collect data regarding commercial and
industrial facilities in Palm Springs and review available data for these sources. In addition, LWA will
review any available data regarding residential use of self-regenerating water softeners and water
supply data particularly with respect to water supply hardness and TDS levels. This information can be
used to estimate contributions to influent TDS from different sources. LWA will use this information to
identify the most effective source control strategies for reducing TDS discharges to the treatment plant.
LWA will prepare the Technical Report required by the WDR using this information to address the
outlined objectives of the Source Control Program:
• Evaluation of source control and methods to reduce TDS concentrations in the discharge to the
evaporation/percolation ponds; and
• Identification of the major sources of salinity into the WWTP collection system (e.g. domestic,
commercial, industrial, water softener regeneration brine).
Per the WDR, LWA will include the following strategies in the work plan provided in Technical Report:
• Description of the municipal entity and facilities, including local ordinances, and rules and
regulations that address the topic of controlling salinity in wastewater;
• Identification and description of entities responsible for controlling each source, if available;
• TDS concentration and waste load (lbs/day)for each of the identified sources and an overall TDS
mass balance for the influent into the WWTP;
• Description of wastewater treatment strategies available and employed at the facility to remove
identified pollutants; and
• Characterization of TDS in the wastewater discharged to the evaporation/percolation ponds and
in the receiving groundwater.

Re: Waste Discharge Requirements Special Studies
Revised Proposal Based on CRWQCB Errata Sheet
Dear Mr. Loar:
We attended the CRWQCB meeting in Yucca Valley on September 21 and listened to the comments
and discussion related to the City of Palm Springs Waste Discharge Requirements. We received the
attached errata sheet approved by the Regional Board. We reviewed our proposal dated August 28, 2017
as it relates to the errata and are providing you with a revised fee estimate and the attached revised
schedule associated with these changes. For your convenience, we have also attached a copy of the
August 28 2017 proposal.
The Regional Board errata are significant to the City of Palm Springs. However, the impacts to the
proposed Hazen scope relate to schedule extensions, streamlining the background documentation for the
nutrient removal evaluation, and removing the public outreach program. This letter specifically responds
to the streamlining of the scope of work by removing subtasks a,b, d and f from Task 3.2. In addition,
this letter removes the public outreach approach scope from Task 4.4.
The attached revised schedule and the revised fee table below will replace the originals included in the
proposal dated August 28, 2017.
