AGENDA TITLE: Adopt Resolution Authorizing City Manager to Execute Amendment No. 1 to Task
Order No. 49 with West Yost & Associates, Inc., of Davis, for Regulatory Services
at White Slough Water Pollution Control Facility ($62,100)
MEETING DATE: February 17, 2021
PREPARED BY: Public Works Director
RECOMMENDED ACTION: Adopt resolution authorizing City Manager to execute Amendment
No. 1 to Task Order No. 49 with West Yost & Associates, Inc., of
Davis, for Regulatory Services at White Slough Water Pollution
Control Facility, in the amount of $62,100.
BACKGROUND INFORMATION: West Yost has been providing regulatory and planning support
services to the City for the White Slough Water Pollution Control
Facility (WSWPCF) under the Regulatory Services for Fiscal Year
2020/21 and Fiscal Year 2021/22 since July 2020.
The City recently received unanticipated Requests for Information (RFIs) from two regulatory agencies
regarding various elements of the WSWPCF treatment process. The RFI's were issued by the United States
Environmental Protection Agency (USEPA) and the State of California Regional Water Quality Control Board
(RWQCB), both require extensive and highly technical responses. Amendment No. 1, if approved, will
expand the current scope of services to address the additional work associated with the RFI's refine
certain State mandated reports, and add $62,100 in additional funds to pay for the amended scope of
work, bringing the total amount of Task Order No. 49 to $255,800.
USEPA RFI
The USEPA has jurisdiction over the WSWPCF biosolids operations in accordance with Section 40, Part
503 of the Code of Federal Regulations (40 CFR 503). The City submits annual reports to the USEPA to
describe the City's compliance with the requirements 40 CFR 503.
The City received an RFI letter dated September 8, 2020, from the USEPA Region 7, seeking
information regarding the City's compliance with requirements of 40 CFR 503, specifically for biosolids
generated at WSWPCF in 2019 and 2020. Six categories of information were requested, with 16
different items required for each year.
Although much of the information needed for the USEPA response would be developed utilizing the
City's Annual Biosolids Reports, the City and West Yost have decided to also refine current reporting
strategies to more accurately reflect current operations and practices as part of this effort. These
strategies include:
• Evaluating nitrogen loadings on a seasonal basis (September through August of the
next year) rather than the annual basis. Evaluating nitrogen loads on a seasonal basis

is more consistent with the farming operations at WSWPCF.
• Evaluating the potential for additional denitrification (nitrogen removal) in the soils
receiving irrigation water containing cannery process water. If it is determined that this
denitrification process is occurring, the applied nitrogen may not be fully available to the
crops being grown, requiring additional nitrogen for crop health and resulting in less
potential for nitrogen overloading.
RWQCB RFI
The following services are required to assist the City in responding to the RWQCB RFI:
• Review the Regional Board comments relative to data and files available in West Yost &
Associates, Inc. files.
• Coordinate with City staff to provide additional data and information to adequately respond
to the Regional Board questions.
• Review City analytical laboratory reports and operational log sheets to confirm various
missing data items and apparent data concerns, such as reported elevated tertiary
effluent turbidity values.
• Communicate with City staff to troubleshoot complicated data questions, including issues
related to the City's Supervisory Control and Data Acquisition system.
• Preparation of a draft and final Technical Memorandum (TM) that presents the City's
response to the Regional Board staffs comments, with multiple attachments providing
backup data and information.
• Prepare a draft cover letter for City staff to finalize to accompany the TM when submitted
to the Regional Board.
• Participate in a conference call with Regional Board and City staff following submittal of
the final TM to the Regional Board.
Staff recommends authorizing City Manager to execute Amendment No. 1 to Task Order No. 49 with
West Yost & Associates, Inc., of Davis, for Regulatory Services at White Slough Water Pollution Control
Facility, in the amount of $62,100.
FISCAL IMPACT: Responding to the RFI's is necessary to avoid potential regulatory fines
and penalties and to maintain a positive relationship with these regulators.
This project does not impact the General Fund.

SUBJECT: Proposal for Engineering Services =
WPCF Regulatory Services for FY 20/21 and FY 21/22
Dear Mr. Roberts:
West Yost Associates (West Yost) appreciates the opportunity to present to you this letter proposal
for ongoing engineering services related to assisting the City of Lodi (City) in meeting permitting
requirements for the City's White Slough Water Pollution Control Facility (WPCF). The scope of
work described in this letter proposal is intended to cover regulatory related support efforts
anticipated to be needed during Fiscal Year 2020/2021 (FY 20/21) and Fiscal Year 2021/2022
(FY 21/22) under the following discharge permits issued by the Central Valley Regional Water
Quality Control Board (Regional Board):
• General Permitfor Municipal Wastewater Dischargers that Meet ObjectiveslCriteria at
the Point of Discharge to Surface Water (General Permit) and the site-specific Notice of
Applicability (NOA) R5-2017-0085-003 for coverage under the General Permit
• Waste Discharge Requirements (WDRs), Order No. R5-2007-0113-01
• NOA WQ-2016-0068-DDW-R5007 (Recycled Water NOA) for coverage under the
State Water Resources Control Board's (State Water Board's) Order WQ 2016-0068-
DDW Waste Reclamation Requirements for Recycled Water Use (General WRRs)
As with our previous regulatory support services contracts with the City, West Yost will rely on
the support from Somach Simmons and Dunn (SSD), an environmental law firm that specializes
in serving California permittees on discharge permit issues, should the need arise.
In previous contracts for regulatory services, West Yost has not included support related to temperature
or toxicity studies that may be required. The City has instead separately contracted with Robertson
Bryan, Inc. to support temperature and toxicity studies. The City has not had recent toxicity issues
under the NOA, but ongoing toxicity support may be needed during term of the new contract. However,
consistent with West Yost's current contract, West Yost assumes that the City will continue to contract
separately with Robertson Bryan, Inc. for support related to toxicity or temperature study efforts and
this proposal does not include significant support related to these efforts.
At the request of the City, the Scope of Work and Fee Estimate provided in this proposal have
been divided into two phases, one for each of the fiscal years covered. It is understood that the
City may authorize services for either both years together or for each year separately.

PROJECT UNDERSTANDING
The following topics are presented as background information pertaining to the proposed work
and define the basic understanding affecting the level of effort:
a General Permit and NOA for surface water discharge
o WDRs for land application
4 General WRRs and Recycled Water NOA
• Dredger Cut water rights reporting
General Permit and NOA for Surface Water Discharge
The General Permit and site-specific NOA, Order No. R5-2017-0085-003, apply to the City's discharge
of disinfected tertiary effluent to Dredger Cut. The Regional Board adopted a revised General Permit in
April 2020. Under our current contract with the City, West Yost has reviewed the revised General Permit
and did not identify any significant changes that would impact WPCF activities.
The current NOA expires on March 31, 2021 and requires submittal of a Notice of Intent (NOI) by
July 1, 2020. The Regional Board limited the term of the current NOA to two years to allow for
supplemental data to be provided for a few monitoring analytes of concern: chronic toxicity,
cyanide, lead, and selenium. Regional Board staff have indicated in recent discussions that it would
be sufficient for the City to meet the NOI submittal requirement by submitting the previous
NOI/Report of Waste Discharge developed in 2018 with a cover letter documenting analysis of
the analytes of concern and attaching the required NOI form signed by the City.
West Yost is in the process of preparing the NOI documents under our current contract with the
City. As part of that effort, we did not identify any compliance issues with the recent monitoring
results for the analytes of concerns. Therefore, the NOI cover letter should include a request that
the term of the NOA be extended for an additional three years to cover the full five-year term, and
that no other changes to the NOA should be made.
The draft NOA is expected to be issued during FY 20/21. The scope of services described herein is
based on assisting the City with reviewing the draft NOA and providing additional information that
may be requested by Regional Board staff as they prepare the NOA and review the NOI materials.
WDRs for Land Application
The WDRs were adopted in 2013 and do not have an expiration date. The WDRs apply to the
following WPCF operations:
o Storage and land application of undisinfected, secondary effluent on City -owned
agricultural properties;
* Storage and land application of industrial process flows, which include seasonal food
processing flows from Pacific Coast Producers, entering the WPCF via the indusial
wastewater sewer system;

■ Biosolids land application on City -owned agricultural properties; and,
Supply of disinfected tertiary recycled water to the Northern California Power
Agency and San Joaquin County Mosquito and Vector Control District.
The WDRs require the following routine monitoring reports with which West Yost has historically
assisted with development or completed on the City's behalf:
■ Quarterly groundwater contour maps that include calculation of groundwater
elevations, an assessment of groundwater flow direction and gradient on the date of
measurement, comparison of previous flow direction and gradient data, and
discussion of seasonal trends, if any.
■ Annual Monitoring Reports that provide an evaluation of the groundwater quality
beneath the WPCF and land application area, determination of compliance with the
groundwater limitations of the WDRs based on statistical analysis for each
constituent monitored for each compliance well, and identification and assessment of
potential groundwater limitation compliance strategies, as needed.
Annual Cropping and Irrigation Reports that provide summaries of the monthly and
annual hydraulic and nutrient loadings from recycled water and biosolids applications
to the WPCF land application area for the prior year, an assessment of compliance
with land application area loading limits and related requirements, discussion of any
corrective actions taken or needed, and discussion of the cropping and irrigation plan
for the coming year.
+ Annual U.S. Environmental Protection Agency (USEPA) Biosolids Application
Reports, which is an online form that document the City's biosolids production and
reuse practices for the prior year.
This proposal assumes West Yost will continue to provide services related to the development of
these reports.
In addition, West Yost has been assisting the City with coordinating with the farmers that manage
the land application area by reviewing the monthly land management reports under the WDRs and
participating in monthly meetings. Under previous contracts with the City, West Yost's
involvement with the City's monthly land management meetings and reports was limited to review
of the reports generated by the City and participation in one annual kickoff meeting at the
beginning of each irrigation season. However, with recent turnover of City staff, West Yost has
been requested to participate in the monthly meetings with the farmers that manage the City's
properties. The need for West Yost's ongoing involvement with these reviews and meetings over
the next two fiscal years is uncertain. Given this uncertainty, we are assuming for this proposal
that ongoing assistance and participation will be necessary.

Finally, the City submitted a report in early 2020 detailing compliance with the Groundwater
Limitations of the WDRs. This was the final compliance step in a six-year schedule that was
developed to allow the City time to complete an evaluation of best practicable treatment or control
(BPTC) measures for the land application area and implement additional BPTCs, as needed, to
allow for compliance. The Groundwater Limitations Compliance Report documented and
concluded that the City is in compliance with the groundwater limitations, with the exception of
impacts that occurred due to past activities near the City's compliance well WSM-2. The report
also documented that existing BPTCs implemented by the City are adequately protective of the
groundwater underlying the WPCF and land application area.
Following their review of the documents provided, the Regional Board could reopen the WDRs to
address the City's evaluation of compliance with groundwater limitations. The Regional Board
could also issue a compliance order related to the ongoing impacts observed near WSM-2. Whether
the Regional Board will reopen the WDRs or issues some other compliance order during the term
of this proposal is unknown. Nevertheless, based on our understanding of the issues and current
Regional Board obligations, we do not think these actions are likely. Therefore, this proposal does
not include specific scope and budget to accommodate a review of revised WDRs. However, tasks
are included for general regulatory program management and as -needed WPCF support services
that could partially accommodate support needed if the Regional Board chooses to reopen the
WDRs and/or issue some other compliance order related to the City's groundwater studies.
General WRRs and Recycled Water NOA
The City completed construction of a tertiary storage pond in late 2019, and storage of disinfected
tertiary recycled water in the new storage pond is permitted under the General WRRs and the
Recycled Water NOA. The Recycled Water NOA also permits a proposed recycled water Fill
Station at the WPCF. The Recycled Water NOA was issued in December 2018 and does not have
an expiration date. Renewal or revisions to the Recycled Water NOA and General WRRs are not
anticipated to occur during FY 20/21 and 21/22.
The Recycled Water NOA has limited monitoring and reporting requirements related to the tertiary
pond operations. West Yost assisted the City under the current contract in developing a template
for the annual report that is required. It is anticipated that the City would need only very limited
assistance, if any, with these ongoing requirements.
The monitoring and reporting requirements under the Recycled Water NOA would be increased if
the City were to construct a Fill Station and implement an off-site recycled water use program.
However, those actions are not anticipated to occur during the term of this project. The scope and
fee estimate provided in this proposal therefore do not include support services related to the
development of and/or permit compliance for an off-site recycled water use program.

Dredger Cut Water Rights Reporting
The City maintains a License Number for Diversion and Use of Water, Permit Number
7424/License Number 3906. This license allows for 5.84 cubic feet per second to be diverted each
year from Dredger Cut for irrigation and stock -watering uses. The specified "Place of Use" under
this permit is an approximately 400 -acre portion of the City -owned agricultural fields that is
comprised of Fields 5A through 5D and 6A through 6D.
The City submits annual Licensee Reports to the State Water Board to document diversions from
Dredger Cut or other in -lieu water use on the Place of Use fields. These in -lieu uses have included
irrigation with recycled water and groundwater. Since 2013, the City has relied on recycled water
and groundwater for irrigation in lieu of diverting water from Dredger Cut.
A licensed water right can be revoked after a long enough period of non-use (typically at least
five years). Under Water Code section 1010, the water user's licensed right is protected from
revocation where water use reductions are due to the use of recycled water - but only to the extent
of the recycled water use. Therefore, the City's continued reporting of in -lieu use is critical for
protecting the City's right for diversions.
The volume of water applied to the designated Place of Use is typically only a portion of the City's
total available under the diversion license. However, because the Place of Use only represents a
portion of the total land application area, the City's overall irrigation water demands are much
more significant than the reported in -lieu amounts. Moreover, the City's irrigation system is not
configured to limit irrigation water applications to only the Place of Use. Therefore, even if a
diversion were to occur, it would be difficult to limit irrigation to only this area. For these reasons,
the City is recommended to seek a change in Place of Use so that the entire City -owned irrigation
area is considered for in -lieu water use. The scope of services includes support related to this effort.
MAJOR ASSUMPTIONS
The City will be responsible for completing any sampling needed to achieve the objectives of the
tasks outlined in the scope of services, and that the City will contract directly with a certified
laboratory for completing any necessary analytical efforts. Under the Regulatory Program
Management task described herein, West Yost will provide support for coordinating any necessary
sampling and analysis efforts with other regulatory needs.
To ensure continued achievement of consistently high-quality work products, and in accordance
with the West Yost Quality Assurance/Quality Control policy, a West Yost staff member at the
Principal Engineer level or higher will review significant work products.
Significant CEQA work will not be required to support the Change Petition and significant protests
will not be filed in response to the submitted Change Petition.
The State Water Board will approve the Change in Place of Use, and ongoing support to the City
with respect to reporting recycled water applied to the existing Place of Use will not be required
beyond FY 20/21.

A San Joaquin Valley Air Pollution Control District Biosolids Rule.
Some of the above -listed items may require support from our legal subconsultant SSD, and a small
budget has been assumed and included for those efforts.
The specific work efforts and deliverables under this task cannot reasonably be determined at this
time, so the associated fee estimate presented in this letter proposal is based on West Yost's
knowledge of the City's current permitting concerns. The scope of work under this task will be
limited to work that can be completed within the available budget. All work will be performed on
a time and materials basis, and monthly invoices will detail the efforts and costs. Depending on
the level of effort required, a scope and budget amendment may be necessary in the future. If the
estimated fee is not expended in the timeframe anticipated for this scope of work, it may also be
directed toward the completion of other efforts.
Task 1.2_Delfyera€lles: Deliverables for this task are dependent on the effort requ{rad, which cannot be
'accurately estimated at th)s t1me. Therefore, West Yost \111 coordinate dollmrables for this task with the

Draft agendas and related handouts for the farmer coordination meetings with sufficient hard copies
brought to each meeting for all anticipated participants.
Task 1.4 Grmundwater Renortina SUS D01 t
West Yost's efforts during FY 20/21 will include support with developing the Quarterly
Groundwater Monitoring Reports for Third Quarter 2020 through Second Quarter 2021 and the
2020 Annual Groundwater Monitoring Report.
For the Quarterly Groundwater Monitoring Reports, West Yost will develop quarterly
groundwater elevation contour maps using the water level data collected by the City on a quarterly
basis. These maps will document the calculated groundwater elevations and the groundwater flow
direction and gradient. In addition, one to two paragraphs will be provided discussing seasonal
trends, if any, and comparing the current flow direction to previous flow directions. It is assumed
the City will incorporate this information in the Quarterly Monitoring Reports submitted to the
Regional Board.
For the 2020 Annual Groundwater Monitoring Report, West Yost will prepare statistical analyses
of 2020 groundwater quality data and the 2020 Annual Background Groundwater Quality
Evaluation, like previous years. The information will be included in a Groundwater Evaluation
Report that is intended to be attached to the Annual Groundwater Monitoring Report developed
by the City. To the extent necessary, these reports will document compliance actions taken or
corrective actions recommended with respect to groundwater limitation compliance.
Task 1.4 Dellyerables: Four figures depicting the contour information to be included in the Quarterly
Groundwater Monitoring Reports for Third Quarter 2020 through Second Quarter 2021. Four emails,
provided quarterly along with the contour: maps, discussing seasonal trends and comparison to previous
groundwater flow directions.
Groundwater Evaluation Report summarizing the statistical analyses and compliance/corrective actions to
be included as attachments to the 2020 Annual Groundwater. Monitoring Report prepared by City staff
The maps and Groundwater Evaluation Report will be provided in an electronic PDF format.
mask 1.5 NOA Adoutiori Suimort
West Yost will review the Draft NOA for errors or concerns relative to the City's current permit and
other recent, similar permits issued by the Regional Board. West Yost will prepare a list of suggested
comments for City consideration and participate in a conference call with City staff to discuss the
suggested comments. Following this discussion, West Yost will prepare a draft comment document
for City staff review. Following this review, West Yost will prepare a final comment document for
City submission to the Regional Board. It is assumed that comments on the Draft NOA, if any, will
be minor and can be addressed in a letter from the City to the Regional Board.
West Yost will also participate in discussions with Regional Board staff, as needed, to discuss the
NOI submission and/or City comments. It is difficult to predict the level of effort that will be
needed to respond to Regional Board requests and review and respond to the draft permit, so the
scope of work under this task will be limited to work that can be completed within the available
budget. All work will be performed on a time -and -materials basis, and monthly invoices will detail

SUBJECT: Budget Augmentation Request for WPCF Regulatory Services for
FY 20/21 and FY 21/22
Dear Mr. Roberts:
West Yost has been providing regulatory and planning support services to the City of Lodi (City) for the
Water Pollution Control Facility (WPCF) under the Regulatory Services for Fiscal Year (FY) 20/21 and
FY 21/22 (the "Project") since July 2020. The purpose of this letter is to request an amendment to the
Scope of Services and budget for this Project.
Specifically, the City recently received two detailed Requests for Information (RFIs) from two regulatory
agencies that require extensive responses. West Yost has also recently identified changes that are needed
to some of the City's previously submitted reports and to the Excel spreadsheets used by the City to
develop routine monitoring reports. The requested amendment addresses these additional services.
Included in this letter are a summary of West Yost's current scope of services; background information on
the additional services needed; the scope of services for the additional efforts and a requested
budget augmentation.
CONTRACTED SCOPE OF SERVICES
The Scope of Services for the Project includes several tasks, split into two phases. Phase 1 Scope of Services
was envisioned to cover tasks required within the first FY (i.e. FY 2020/2021) and Phase 2 within the second
FY (i.e. FY 2020/2021). FY 20/21 runs through June 2021, so the Project is currently within Phase 1.
Phase 1 Scope of Services includes the following tasks:
• Task 1.1 Project Management
• Task 1.2 Regulatory Program Management
• Task 1.3 Land Application Monitoring Coordination
• Task 1.4 Groundwater Reporting Support
• Task 1.5 NOA Adoption Support
Mr. Lance Roberts
December 23, 2020
Page 2
• Task 1.6 Place of Use Change Petition Support
• Task 1.7 As -Needed WPCF Support Services
The efforts described herein would be covered under Task 1.2, which is described as follows:
West Yost anticipates that the City will continue to require ongoing assistance related to understanding
general regulatory compliance issues and implementing the measures needed to achieve compliance. In
addition, the Regional Board may require special studies or reporting requirements with which the City
may want assistance during FY 20/21. Assistance under this task may include, but is not limited to, the
following services:
• Providing assistance to the City, as needed, for developing responses to Regional Board
[Central Valley Regional Water Quality Control Board ] requests.
■ Helping the City to develop monitoring programs, as appropriate.
■ Maintaining a database of regularly collected monitoring data.
• Assistance with developing or reviewing monitoring reports required under the City's
permitting program.
■ Assistance with responding to Notices of Violation or other potential
compliance notifications.
• Supporting the City to respond to mercury monitoring and reporting requirements required
as part of the Regional Board's mercury Total Maximum Daily Load effort.
■ Completing reviews of collected monitoring data to identify potential future
regulatory concerns.
• Providing support to the City and the Pacific Coast Producers in addressing food processing
waste disposal issues.
• Attending and preparing for meetings to discuss the results of regulatory program
management activities.
• Reviewing permits and other regulatory guidance documents issued by the Regional Board
and State Water Board that would be applicable to the WPCF.
• Providing minor support related to the following:
— Title 22 Issues;
— Toxicity Reduction Evaluation efforts being completed separately; or
— San Joaquin Valley Air Pollution Control District Biosolids Rule.
Some of the above -listed items may require support from our legal subconsultant SSD, and a small budget
has been assumed and included for those efforts. The specific work efforts and deliverables under this
task cannot reasonably be determined at this time, so the associated fee estimate presented in this letter
proposal is based on West Yost's knowledge of the City's current permitting concerns. The scope of work
under this task will be limited to work that can be completed within the available budget. All work will be
performed on a time and materials basis, and monthly invoices will detail the efforts and costs. Depending
on the level of effort required, a scope and budget amendment may be necessary in the future. If the
estimated fee is not expended in the timeframe anticipated for this scope of work, it may also be directed
toward the completion of other efforts.

As noted, however, assistance with as -needed support under Task 1.2 is limited to the budget identified
for the task. The additional services needed to respond to the two RFIs, revise the previously submitted
reports, and update the Excel spreadsheets used by the City to develop routine monitoring reports
exceeds the available budget for this task.
BACKGROUND
Regional Board RFI
The land application practices activities associated with the WPCF are permitted by the Regional Board
under Waste Discharge Requirements and Master Reclamation Permit Order No. R5-2007-0113-01
(WDRs). The WDRs require submission of monthly, quarterly and annual Self -Monitoring Reports (SMRs)
to the Regional Board.
On October 13, 2020, Regional Board staff submitted comments and questions to the City on the City's
April 2019 SMR; and on October 27, 2020, the Regional Board submitted an additional set of questions
along with a table listing missing data for monthly and quarterly SMRs from the period of April 2019
through August 2020.
USEPA RFI
The United States Environmental Protection Agency (USEPA) also has jurisdiction over the WPCF biosolids
operations in accordance with Section 40, Part 503 of the Code of Federal Regulations (40 CFR 503). The City
submits annual reports to the USEPA to describe the City's compliance with the requirements 40 CFR 503.
The City received an RFI letter dated September 8, 2020, from the USEPA Region 7 seeking information
regarding the City's compliance with requirements of 40 CFR 503, specifically for biosolids generated at
the WPCF in 2019 and 2020. Six categories of information were requested, with sixteen different items
required for each year.
Although much of the information needed for the USEPA response would be developed under the City's
Annual Biosolids Reports, the City and West Yost have decided to also evaluate alternative reporting
strategies to more accurately reflect current operations and practices as part of this effort. These
strategies include:
Evaluating nitrogen loadings on a seasonal basis (September through August of the next
year) rather than the annual basis. Evaluating nitrogen loads on a seasonal basis is more
consistent with the farming operations at the WPCF.
Evaluating the potential for additional denitrification (nitrogen removal) in the soils
receiving irrigation water containing cannery process water. The WPCF receives cannery
process water during the Summer and early Fall, and the carbon to nitrogen ratio of this
water can be relatively high during the peak canning season and encourage growth of
denitrifying microbes in the soil. If denitrification is occurring, the applied nitrogen loadings
may not be fully available to the crops being grown, and additional nitrogen would be
needed for crop health.

Mr. Lance Roberts

Revised Reports
In reviewing the City's SMRs as part of preparing the RFI response, it became apparent that the City's
recent quarterly SMRs have not included details on the well sampling practices, the log reports of
sampling, and the historic groundwater data summaries, which the WDRs require as part of the quarterly
SMRs. Therefore, the City will need to submit revised quarterly SMRs for Fourth Quarter 2019, First
Quarter 2020 and Second Quarter 2020.
The Regional Board RFI also revealed that the City's monthly April 2020 SMR submittal was did not include
several items required by the WDRs, such as hydraulic and nitrogen loading sheets and field observation
sheets. Because so much information was missing from this SMR, West Yost recommends that the City
submit a complete, revised April 2020 SMR.
Finally, although not reviewed by the Regional Board, the City will need to resubmit the May through
October 2020 SMRs to address similar data issues that were identified by the Regional Board with the
April 2019 through August 2020 reports.
Reporting Spreadsheet Updates
Updates to the Excel spreadsheets used for routine monthly, quarterly and annual reporting are needed
for the following reasons:
In preparing the responses to the Regional Board RFIs, we identified some minor
improvements that will assist the Regional Board with future review.
• The spreadsheets need to be updated to provide the ability to consider seasonal nitrogen
loadings and denitrification impacts that were discussed previously
• The City recently requested that the Regional Board allow for some minor agricultural field
consolidations with respect to reporting of irrigation water loadings, and changes to the
spreadsheets are needed to reflect these consolidations.
• The City installed a new irrigation flow meter in May 2020 that includes measurement of
both treated WPCF effluent from the storage ponds and industrial influent, whereas the
previous flow meter did not include the industrial influent flows. The current spreadsheet
allows for reporting both ways, which can create confusion. A small adjustment to the
spreadsheets will prevent future confusion related to this flow meter change.
West Yost recommends that updated spreadsheets be developed through 2026. While the level of effort
needed to provide spreadsheets for subsequent years is minor, we recommend that the City revisit the
need for these spreadsheets at a later date, as additional updates may be identified over time.
Once new spreadsheets are developed, they need to be uploaded on the City's server and linked to the
City's files. Like past spreadsheet uploads, a West Yost staff member would travel to the WPCF to place
the new files on the server and set up the links.
