STAFF REPORT
TO: TOM DUBOIS, CITY MANAGER
MEETING DATE: MARCH 17, 2025
FROM: DAN LAFONTAINE, PUBLIC WORKS DIRECTOR
SUBJECT PUBLIC WORKS DEPARTMENT REPORT FOR FEBRUARY 2025 Objective: The objective of this staff report is to provide a monthly status update regarding activities within the Public Works Department.

Executive Summary: As the majority of winter passes (with the exception of a few atmospheric rivers) we turn to spring and a time of growth. In public works, the nicer weather means that we have growth of landscaping that we planted in late summer (gateway park) and nice enough weather to finish some long outstanding projects (cemetery road paving) while also the growth of all types of unsightly weeds that require spraying around town. During the past month we have made substantial progress with fuel fire mitigation by removing debris and brush from the Minehead site. We also managed to close one lane of Gopher Flat Rd. and removed all the bush that had been encroaching onto our road. We will continue to tackle the biggest areas of fuel mitigation while also working to spray and reduce the growth of new fuel.

In terms of sustainability, the public works team has prepared a list of collection system work that we are bringing to the council. The list includes seven projects that have been on our problem list for infiltration and/or repeat clogs. We also had the flow meters pulled as the consultant believes that enough data has been collected. We will be receiving a briefing in the next few weeks. We also submitted our individual water balance and are collaborating with our regional partners to produce a joint water balance, which will be vital information as we move forward with our WWTP project.

Upcoming: We will also be sitting down with our flow meter consultant to review data and discuss our targeted approach to repairs that will maximize every dollar that we spend. Working with our local regulators, the water board has requested a site visit of ARSA to develop a better understanding of our waste disposal system. We will also be collaborating with our regional partners to produce a joint water balance. We will begin preparing the RFQ for the new WWTP and hope to have that our to bid in April. We will also be working with the ARSA engineer to fully define and scope our Henderson underdrain project. Minie Provis park will also be getting an upgrade between the community building and the playground as we look to upgrade the park and improve the accessibility to everyone.

Detailed Summary: Below is a detailed summary and/or status of the main PW responsibilities; Collection System, Wastewater Treatment Plant, Effluent Disposal, Streets and City Right of Way, Parks and Buildings, and Service Callouts.

Collection System Status:

CIP work
 On February 25 and 26, 2025, RH Borden removed the collection system flow meters from the sewer manholes. During the removal all manholes were scanned for leaks (an additional service being given to the City). The data is currently being compiled, and we will be getting the next steps and recommendations in March. If the data the flow meters have collected is not adequate (not enough storms), the consultant will redeploy the flowmeters at no cost to the City.  The list of collection system repairs has been completed and finalized. Plans and specifications are currently being developed. The list of collection system projects identified this year are the following:
o Replace Main from Rayland Drive to Highland Drive
o Install Manhole at rear of NAPA Auto Parts
o Replace Main on Dennis Street
o Replace Main from Sutter Hotel to Creek
o Replace Main at Highway 49 from Highland Drive to Old Sutter Hill Road o Replace Main at Greenstone Terrace
o Replace Main at rear of Duplexes at 50 Eureka Street
SSMP Activity
Calls for service.
 2/11/2025; 175 Spanish St. plugged City Main.
 2/27/2025; 140 Eureka St. plugged City main. This City owned main is only three inches in diameter and is made of vitrified clay. The sewer line was installed in the 1948 sewer collection system upgrade. This line is in need of being replaced.

Sewer System Cleaning and Maintenance.
 For January 2025, there was 510 feet of sewer line cleaned. The total amount cleaned for the calendar year 2025 is 1,021 ft. The total cleaned for the calendar year 2024 is 19,207 feet.

Wastewater Treatment Plant Status:

The WWTP met all the effluent quality discharge requirements for the month of January 2025.

Section 13, Item H.

Plant Compliance Issues: The monthly January 2025 report was electronically submitted to the Regional Water Quality Control Board.

Operational Strategy Modifications:
 The rag bin was hauled on February 21, 2025.
 We continued normal sludge wasting in January with 18K gallons dewatered.  Roto strainer #3 is currently being installed. New couplers had to be ordered and were received in February. Operators are currently piecing all parts of the roto strainers back into service.
 One of the two E-pumps showed signs of failing (low amperages while running at full capacity) and was replaced with a new pump.
 The second Chlorine tank has been moved into the chlorine building to be plumbed into the process train.
 The chlorine pumps (lead and lag) have shown signs of failure (motor overheating and constant tripping). New pumps have been ordered, and lead times have been estimated at 3 months. The old pumps continue to operate until we can get the new ones delivered and in hand. In February the pumps operated and did not have to be rebuilt.
 We continue to meet with firms to discuss the new WWTP. We are hopeful that in the next few months we will issue a request for qualifications (RFQ) to move forward with the WWTP direction and design.

Effluent Disposal
 Bowers and Hoskins irrigation were discontinued for the season on October 31, 2024.  Ione has received approximately 250 acre-ft from the ARSA pipeline for the 2024 disposal season.
 On February 24, 2025, ARSA submitted a revised water balance to the regional water board that included. The results of the ARSA water balance indicated that the ARSA system in combination with the Castle Oaks Water Reclamation Facility and Castle Oaks Gold Course can adequately contain and dispose of all Sutter Creek WWTP effluent, precipitation, and runoff for the RP100WY without violation of storage capacity or agronomic application rates. These calculations result in only 12.5 to 13.0 acre-feet of surplus disposal capacity in the disposal system. Capacity for additional flows from other dischargers appears to be limited. Both Mule Creek State Prison and the City of Ione submitted their individual water balances. All parties are currently waiting for comments from the water board before commencing with the joint water balance.
 The City has retained HydroScience to assist with the project management of the Henderson underdrain repair in late summer early fall of this calendar year.

HydroScience toured the Henderson reservoir on February 12, 2025, to review the plans and specifications (produced by Stantec in Jan 2023). We anticipate having a request for proposal ready for the ARSA Board to review in March. Construction of the underdrain is anticipated to begin in July 2025.
127
Section 13, Item H.

 The replacement flow meter for the Bowers irrigation has arrived and will be installed in the coming months.
 Ongoing maintenance of the cattle water troughs along the pipeline. Irrigation sprinklers and valves are being repaired constantly.
 Weed and rodent abatement at the three reservoirs.
 Send weekly updates to the Regional Board on reservoir levels and volumes.  Daily flow checks and level readings.

Streets and City Right of Way.
 On February 19, 2025, public works workers received non-DOT flagger training in the Cities commitment to ensure the safety of every City employee while working in the public roadways.
 The Public works team and City engineer toured the walking path to see what can be done about erosion of the path and mud being washed into the driveway. During the tour, the homeowner pointed out that the walking trail sign was beginning to fail and needed assistance. Public works fixed the post by adding some new concrete. See below:

Walking Sign Before Walking Sign after fixing
 The cemetery road has been repaved, and the City cemetery loop is back open. See picture below:
128
Section 13, Item H.

 Another round of sidewalk shaving has been performed in the downtown area. This time Precision Concrete shaved all remaining trip hazards on Main street from Eureka to Gopher Flat.
 The public works team has been at work filling potholes around town in anticipation of more rain to come, hopefully.

Parks and Buildings
 On March 5, 2025, The California Department of Fish and Wildlife (CDFW) issued a second version of the draft agreement to address the Cities concerns. The City is currently reviewing the changes to the agreement and will respond in 30 days.  Public works has begun to spray for weeds. In an effort to promote our fire fuel mitigation efforts around the City we began with spraying the triangle lot located between Ridge Road and Prospect Drive across from the bowling alley at the end of February.
 While driving around I noticed that the flowers had begun to grow at the Gateway park.

We feel that the new bark and the flowers look great and provide a beautiful entrance to the City. See below:
129
Section 13, Item H.

 CalFire crews were present for a few weeks during February and have cleared a lot of debris off the shoulders of roads. Working with CalFire, Public works managed to clear both Gopher flat road just past Werner Road on February 26th. The crews were also able to spend a few days at the bottom of Sutter Hill Rd and cleared Old Hwy 49 from the book to Sutter Hill Rd. See pictures below of the completed work at both locations below:

1.0 Purpose and Objective
This technical memorandum is a response to the California Regional Water Quality Control Board’s August 14, 2024 letter to the California Department of Corrections and Rehabilitation (CDCR) regarding the treatment and disposal capacity of the Wastewater Treatment Plant (WWTP) serving Mule Creek State Prison (MCSP). The wastewater treatment system serves not only MCSP, but includes the Mule Creek Infill Complex (MCIC), the CalFire Training Academy (CFTA), and the Preston Youth Correctional Facility (PYCF). In particular, the letter, issued under Section 13267 of the California Water Code, requested:
• Forecasted wastewater flows for the next 5 years, based from official planning documents, broken down by each source;
• The forecasted wastewater flows should be broken down for all influent sources, including Mule Creek State Prison, the CalFire Training Academy, and the Preston Youth Correctional Facility; • Any changes to treatment and/or disposal capacity or demand caused by the selected option related to the industrial waste stream;

• The additional disposal capacity from the selected option in Land Application Area Development Technical Report required by the October 6, 2023, Notice of Violation.

If the facility does not have sufficient capacity to treat and dispose of all wastewater onsite, the response is requested to identify the volume of excess effluent that would need to be treated and disposed each year without causing a permit violation or a condition of pollution.

The water balance needed to identify the treatment and disposal capacity conditions noted above, is required to comply with the requirement and guidance of a document attached to the letter entitled: Attachment A: Requirements for Water Balance and Calibration. It is to be limited to CDCR owned and operated property and facilities.

2.0 Historical Water Balance Calculations and Summary of Results The previous water balance submitted to the Regional Water Quality Control Board, Central Valley Region (RWQCB) was completed on June 1, 2020, and prepared by Kjeldsen, Sinnock, and Neudeck, Inc. (KSN, Inc). The balance was performed in response to a Notice of Violation (NOV) issued on August 13, 2018 and included with a Report of Waste Discharge submitted to the RWQCB. That NOV requested an “Evaluation of compliance under the Waste Discharge Requirements (WDRs) under reduced land application area (LAA)”. Since that submission, the LAA use for disposal has not changed.

MCSP has a total of 6 areas used as LAAs, composing a total of approximately 200 acres. The effective area of these LAAs were estimated through an evaluation of historical LAA layouts, modifications to the irrigation system/LAAs as a result of improvements to the site (e.g., construction of the Mule Creek Infill Complex [MCIC]), and through examination of existing aerial imagery indicating the area effectively having treated effluent applied.

The purpose of the MCSP LAAs is to achieve land disposal of treated effluent originating from the MCSP, CFTA, and remaining limited wastewater generated from the now closed PYCF. Land disposal is accomplished through evapotranspiration and limited percolation of treated effluent applied to the LAAs, with remaining effluent constituents being treated, retained in the soil, and/or volatized into the atmosphere. Waste Discharge Order R5-2015-0129 (2015 Order or WDRs) issued for the WWTP includes discharge specifications and LAA specifications to protect beneficial uses of receiving waters. Receiving water objectives are as listed in the Basin Plan and are applicable as noted in the 2015 Order.

The last water balance proposed changes to the management and the operation of the LAAs, which were incorporated into the June 2020 Report of Waste Discharge Technical Report. In particular, the last water balance proposed that MCSP operations promote the establishment of perennial vegetation on the LAAs through the elimination of the use of herbicides and a reduction of disking and mowing of the LAAs. The last water balance also looked at salinity and nitrate in the LAAs. It recommended rotation of the LAA of several years to promote leaching of salts and promote vegetative growth and minimize soil accumulations that may be detrimental (i.e., salt accumulations).

Projected loading was estimated for each LAA and over a range of hydraulic conditions for a projected 0.57 Mgal/d Average Dry Weather Flow (ADWF), where 0.57 represented the projected average influent flow to the MCSP WWTP 136

from MCSP, the MCIC, CFTA, and PYCF. Water balance evaluations of storage and disposal were performed with that flow scenario and assuming that disposal was performed using:
• Application to the currently existing LAAs,
• Discharge to the Castle Oaks Water Recycling Plant (COWRP) of no more than 350 ac-ft per year (approximately 114 million gallons)
• With a 1-in-100 yr precipitation season followed by 1-in-50 and average year precipitation seasons.

The resulting calculations showed that the projected average influent flow could be treated and disposed of by the current infrastructure. However, under a 1-in-100 year precipitation season with a 0.57 Mgal/d flow would result in water that cannot be applied to fields without the need for discharge of up to 350 ac-feet (114 million gallons) of excess water to the COWRP system. Some conservative assumptions do affect the result, such as using the crop coefficient for a wet year and assuming no percolation out of the MCSP effluent storage reservoir. While not inappropriate for high rainfall season, using a wet year crop coefficient adds another conservative factor to the estimate that reduces how much the LAA can dispose. This is a worst-case scenario with a very low probability of ever occurring.

3.0 MCSP, MCIC, Cal Fire, and PYCF Historical Flows and Flow Projections The flows treated by MCSP WWTP have generally remained stable since the last water balance. As noted above, the MCSP system has several sub-systems, in addition to MCSP, that use the system for wastewater treatment and disposal. They are MCIC, PYCF, and the CFTA. A summary of the recent average relative contribution by source to the MCSP WWTP is given below in Table 1.

3.1 MCSP and MCIC Flows and Population
As can be seen from Figure 1, the MCSP WWTP influent flow captures the total influent flow from all sources with a separate measurement of flows originating from the MCIC and PYCF and CFTA. To calculate the flows originating from the MCSP only, those other flows must be subtracted from the WWTP influent flow total. The total MCSP WWTP influent wastewater flows have increased since 2016 as the populations between MCSP and MCIC shifted and as the MCIC population increased to current levels, resulting in a recent stabilized average dry weather influent flow1 of approximately 0.51 Mgal/d. A review of winter-month average flows and storm-period daily flow totals, indicates that the overall system appears to have some Infiltration and Inflow (I&I). This is indicated by recent peak day influent flows of

1.04 Mgal/d (March 3, 2019), 0.97 Mgal/d (January 28, 2021) and recent peak month influent average flow of up to

0.58 Mgal/d (Feb. 28, 2023). During these time periods the combined MCSP/MCIC population average was 3,876, with a range of 3,743 to 4,051. Reported population data is presented in Exhibit A.

While MCSP does not have industrial waste streams per se, MCSP has several training facilities for prisoner rehabilitation. These include garment and mattress assembly, medical/clinical training, janitorial and HVAC training, coffee roasting, lunch packaging, woodworking and metal working training. None of these facilities appear to generate much wastewater. There is also a meat packing and a laundry. The additional wastewater stream associated with the meat packing is limited but does exist. It is mostly limited to the daily post-operation wash down. The laundry facility operates regularly, producing wastewater generated from laundry service provided to the MCSP, MCIC, CFTA, and other Northern California institutions. However, the wastewater flows from the meat packing and the laundry services are included in the MCSP WWTP influent flow measurement and are part of the per-capita distribution. The waste discharge requirements, Order R5-2015-0129, assigned 0.13 Mgal/day for the laundry. However, adding that flow to the actual measured influent flows would result in a double counting error because they are included in the existing flow basis.

MCIC wastewater flows have nominally increased since 2019 but stabilized at about 0.14 Mgal/d through 2024. The system appears to have no discernable infiltration and inflow as seen with no identifiable flow increases during winter storm events such as the storms in late December 2022 and early January 2023 and through March 2023. MCIC also has rehabilitation and training activities. Like MCSP, those activities do not appear to contribute much to the waste stream and are captured in the per capita flow estimate for the facility. Historical MCSP and MCIC average monthly flow totals and population is shown below in Figure 3 through September 2024. 1 Calculated based on the average of monthly flows for June, July, and August. 140

3.2 CFTA Flows and Population
CFTA wastewater flows vary seasonally and year to year depending upon the number of trainees at the facility. The program objective for cadet training is set by the Governor’s office on an annual basis2, with training assignments to the various statewide facilities varying based on facility capacity and other factors. The recent annual cadet population at the CFTA has been approximately 1,216 cadets in 2023 and 1,373 cadets in 2024, and a projected 1,321 cadets for 2025, with a weekly staff of 1203. Current CFTA facilities are limited by the 238 dormitory-style beds for cadets (see Exhibit B) with the 120 staff supporting the CFTA operations split into shifts. The facility has a cafeteria that serves breakfast and lunch. The dormitories have laundry facilities for the residents and for fire equipment. CFTA sends all bedding to be washed to MCSP.

Assuming that 75% to 100% of the CFTA bed capacity is used for any given cohort of cadets, then the recent historical and projected 2025 cadet annual totals would suggest that five to eight training groups come through the CFTA per year. CFTA staff indicated that typical courses rotations occur from January to July4. A conservative assumption would be that the facility is fully occupied with 238 cadets and 120 staff during each training session.

Historical flow monitoring for the CFTA occurred at a flow monitoring manhole on the CFTA site, with an existing combined flow meter located at the MCSP WWTP headworks intended to measure combined flow from the CFTA and PYCF using a flume and level sensor on the incoming wastewater line at the WWTP headworks. In mid-2023 (around May 2023) the CFTA installed a flow measurement device in a manhole that serves the CFTA facilities.

measurement device is reported to consist of a SonicSens 3 level sensor and data logging device. At this time the accuracy of this instrumentation to measure and record flow totals in this manhole are suspect and therefore this flow data is not considered to be accurate. Because of a noted backwater effect on the flume level sensor at the MCSP WWTP headworks, the combined influent flow intended to measure flow from the PYCF and CFTA is not expected to be accurate. Therefore, existing, and potential future flows from the CFTA are estimated as outlined below in Table 2.

Cadet Trainees 100 238 23,800
Staff 20 120 2,400
Total 26,200
The above estimated wastewater generation rates are supported by recent recorded potable water use at the CFTA from Amador Water Agency records provided by CFTA for 2020, 2022 and 2023. The records were evaluated for recent average daily use in 2022 to 2023 during the highest expected occupancy time frame of March to June. The average daily water use from 2022 to 2023 during the maximum occupancy timeframe is estimated at 25,952 gallons per day.

3.3 PYCF Flows
PYCF is currently in a warm shut down status meaning that the facilities are maintained in a semi-ready status for potential use or occupancy sometime in the future. At this time there are no plans for the PYCF to be occupied with any wastewater to be discharged to the MCSP WWTP. The only flows coming from the PYCF are associated with rain events. Due to its age, the wastewater system is interconnected with the old storm sewers giving the system significant flows during wet weather. The flow from the PYCF facility is negligible for most dry days as evidenced by the available flow records for the dry months of the year, for 2022 and 2023. 2024 flow data are indicative of reported water system leaks that were discovered in February and partially repaired in May 2024. Current dry-period flow monitoring for the PYCF suggests that water leaks still exist in the PYCF and are continuing to contribute to the wastewater stream. Since circa 2014, a separate flow meter at Preston Lift Station has existed to record and report daily flow from the PYCF. However, for the purposes of this assessment, it was found that the only useable data started in January 2022. The maximum recorded flow during wet weather is 293,898 gallons per day (Dec. 31, 2022).

Table 3 presents an assessment of the recent water year 2023 and 2024 meter data and Infiltration and Inflow as a function of monthly total precipitation. This recent data is compared to the previous estimates of I&I generated during preparation of prior MCSP technical studies and as used in the June 2020 Report of Waste Discharge, as estimated based on water year 2017 data. Based on this analysis, continued use of the water year 2017 PYCF flows are supported for this water balance as a reasonably conservative basis for flows occurring during a 1-in-100 year precipitation season from the PYCF system.

1PYCF Leaks found and reported in the Wastewater Transmission Line Inspection Form, February 2024. 2PYCF Wastewater Transmission Line Inspection Form noted no leaks as of June 2024. Uncharacteristically high flows are still reported from June to September 2024 indicating leaks still exist.

3.4 Flow Summary and Estimates
Flows used in the water balance calculations consist of the following:

1. Average dry weather flows for the MCSP, MCIC, and CFTA; and

2. Monthly I&I rates for the MCSP, MCIC, and PYCF.

For these monthly-based water balance calculations, I&I is estimated based on subtracting the flow of wastewater origins, calculated as the ADWF, from the total influent flow on a monthly basis. This requires a reasonable estimate of the flow of wastewater origins contemporaneous with the winter-period flow assumed to include I&I. The June 2020 Report of Waste Discharge evaluated available flow data from Water Year 2017 as a means to estimate I&I under a 1- in-100 year precipitation season. The evaluation summarized in Table 4 presents the estimated I&I from recent MCSP 143

Comparing the 2017 estimated infiltration and inflow to recent 2020 through 2024 water year system performance, the 2017-basis is supported and has been used to estimate infiltration and inflow into the system during a 1-in-100 year precipitation season. Average year infiltration and inflow has been estimated based on the average rate indicated by water years 2020 through 2024.

The current flows of wastewater origins consist of flows from the MCSP and MCIC population and activities and the CFTA population and activities. Recent influent flow monitoring indicated an average dry weather flow (ADWF) 6 of

0.51 Mgal/d, up from the previous ADWF of 0.48 Mgal/d as indicated by the average of 2018 and 2019 data. This increase in ADWF is likely due to a combination of variability in MCSP/MCIC populations, nominal increases in water use in the MCIC as the facilities’ operations have matured, and potential nominal increase in activity at the CFTA (although not documented). Considering these conditions and the estimated values presented above, Table 5 summarizes the estimated wastewater flow contribution per system served by the MCSP WWTP. 6 Calculated for the MCSP based on the average of flows from June, July, and August. 144

3.5 Projection of Future Flows
The August 14, 2024 Water Code Section 13267 letter requests that CDCR project wastewater flows over the next 5 years. Unlike a traditional California community, such as the City of Ione or City of Sutter Creek, the population of institutional facilities such as the Mule Creek State Prison and the Cal Fire Training Academy depend on facilities capacity (such as bed capacity), staffing to support that capacity, and statewide policies and directives. At this time there are no known plans for expanding or modifying the MCSP or CFTA institutions within the next five years and therefore future flows to the MCSP WWTP will be driven by statewide policy such as incarcerated persons population management amongst the CDCR facilities across the state and the Governor’s year-to-year direction on Cal Fire cadet training. CDCR’s current projections for total incarcerated persons population indicate an average approximately 2% reduction per year through 20287. Within the MCSP system (including the MCSP and MCIC), the incarcerated persons population will be limited to the capacity of the existing facilities and a degree of “overcrowding” that may occur as CDCR manages the statewide incarcerated persons population and its projected decrease over the next five years. As noted above and documented in Exhibit A, the recent total MCSP/MCIC population has ranged from 3,743 to 4,051 incarcerated persons, with an average of 3,876 incarcerated persons, with a report design capacity of 3,284 incarcerated persons as presented in Exhibit A. This current incarcerated persons population level indicates an occupancy at 114% to 123% of design capacity. Although statewide the total incarcerated persons population is projected to decrease, for the purpose of this capacity assessment the current population levels are assumed with a 5% safety factor applied as noted in Table 6. As an alternative potential worst-case condition, Table 6 also presents an estimated maximum potential MCSP/MCIC occupancy at 4,926 incarcerated persons at 150% of design capacity as a basis for projection.

3.6 Existing Wastewater Treatment System
As documented in the Mule Creek State Prison Wastewater Treatment Plant Improvements design plans, dated August 29, 2014, prepared by GHD, and as reported in the Mule Creek State Prison Wastewater Treatment Plant Improvements Completion Report, dated May 31, 2017, the existing MCSP WWTP has the following hydraulic design capacity:
• Average daily influent flow capacity of 1.0 Mgal/d
• Dry weather daily influent flow of 1.0 Mgal/d
• Peak hour influent flow of 2.86 Mgal/d
• Peak day influent flow of 1.7 Mgal/d
• Peak month influent flow of 1.3 Mgal/d
Other than when the RWQCB requested that CDCR divert stormwater to the WWTP, historical influent flows have been well below the design capacity of these facilities. Projected future flows as noted in Table 6 are below these reported design capacities. The existing MCSP wastewater treatment facilities were designed and constructed to allow for the conveyance and treatment of wastewater under a variety of conditions. CDCR implements a maintenance program on wastewater treatment processes and elements of the sewer system described in detail in the MCSP Sewer System Management Plans (SSMP)8rr . For additional overflow prevention, the MCSP system is equipped alarms and reliability features including alarms and communications to Plant Operations for high water events. 8 SSMP, Page 11 & 12.

4.0 MCSP Effluent Storage and LAA Characteristics and Operations The effluent storage reservoir and LAAs are the components that allow the MCSP wastewater system to store and apply treated effluent in a controlled manner protective of water quality. The effluent storage reservoir, like its name implies, holds effluent until climate and LAA conditons and the operators are ready to apply wastewater to the LAAs.

The LAAs are provided wastewater when they can readily receive the wastewater in compliance with the LAA discharge specifications. On November 26, 2019, a Land Application Area Management Plan was developed with the intent of aiding operators in meeting the requirements of WDR R5-2015-0129, with the ultimate objective of maintaining or improving groundwater quality to the extent practicable. This was submitted to the Regional Board on that same date. The long-term goal of land application management practices is to be able to maintain and operate the LAAs for the life of the treatment facilities. These characteristics, and the below specifics, have been incorporated into this update to the MCSP water balance calculations.

4.1 Land Application Area Characteristics
MCSP operations staff document the volume effluent applied to each LAA or combination thereof, as well as irrigation durations to each LAA on a daily basis. The approach for calculating the distribution of treated effluent applied to each field involved the following sources of information:
• Daily recorded total irrigation volume applied to the LAA as recorded by the irrigation pump station flow meter;
• Sprinkler counts and estimated spray nozzle capacities; and • Daily recorded irrigation durations to each land application area.

Each LAA is a bit different, not only in size but soil depth and soil type, shown below in Figure 4. The soil type and depth is balanced with the irrigation timing and duration. CDCR has conducted significant investigation and characterization of the LAAs and their underlying soil characteristics as detailed in the June 2020 Report of Waste Discharge and the following technical reports submitted to the Regional Water Quality Control Board:

1. Technical Report Update, Mule Creek State Prison, October 15, 2018

2. Land Application Area Soil Sampling Plan, Mule Creek State Prison, October 15, 2018

3. Updated Land Application Area Management Plan, Mule Creek State Prison, November 26, 2019

4. Land Application Area Soil Evaluation Report, Mule Creek State Prison, November 26, 2019 The most current and relevant information regarding the MCSP effluent reservoir and LAA facilities characteristics from these prior studies have been incorporated into the enclosed water balance calculations. 147

As confirmed through site investigations and facilities mapping, the existing MCSP LAAs consist of six distinct irrigation areas, separated by location and irrigation system piping, with the estimated effective area as summarized in Table 7 9 .

1 28
2 28
3 31
4 39
6 31
7 43
Total 200
The effective area of these LAAs were estimated based on an evaluation of historical LAA layouts, modifications to the irrigation system/LAAs as a result of improvements to the site (e.g., construction of MCIC), and through examination of existing aerial imagery indicating the area effectively having treated effluent applied. The LAAs are managed to avoid any tailwater under normal application practices. This is achieved by closely monitoring and controlling the application durations such that surface soil saturation and runoff do not occur. Each LAA has a 3 to 5 ft earthen berm constructed along the downslope perimeters. Tailwater berms are located downslope of the LAAs and are maintained to capture and contain any runoff that may occur. The LAAs are not operated during or immediately following precipitation events.

Below is a description of the LAAs, and their relative use.

LAA1 is located on the Southwest side and is currently divided into three sections for irrigation purposes. Historically LAA1 has been used mostly during the Fall, Spring and Summer (May through October). LAA1 is irrigated about 16 days per year, resting mostly during the Winter.

LAA2 is located in the upper Northwest of the effluent storage reservoir. It is currently divided into two sections for irrigation purposes. Irrigation of LAA2 has historically been mostly during the Fall, Spring, and Summer (May through October). LAA2 is irrigated about 16 days per year, resting mostly during the Winter.

LAA3 is located on the North side of the effluent storage reservoir and is currently divided into three sections for irrigation purposes. Historical irrigation of LAA3 is mostly during the Fall, Spring and Summer (May through October).

LAA3 is irrigated about 14 days per year, resting mostly during the Winter.

LAA4 is located East of the effluent storage reservoir. It is currently divided into two sections for irrigation purposes.

Irrigation of LAA4 is mostly during the Fall, Spring, and Summer (May through October). LAA4 is irrigated about 25 days per year, resting mostly during the Winter.

LAA6 is located on the Southwest side and is currently divided into three sections for irrigation purposes. Irrigation of LAA6 has been typically all year long when precipitation conditions allow. LAA6 is irrigated about 27 days per year.

LAA7 is located on the Southwest side and is currently divided into three sections for irrigation purposes. Irrigation of LAA7 has typically been almost all year long when precipitation conditions allow. LAA7 is irrigated about 41 days per year.

4.2 Effluent Storage Reservoir Characteristics
The effluent storage reservoir is an integral component of the treatment system. The effluent reservoir is an earthen dam that stands 51 feet high. It is certified by the Department of Water Resources (DWR) and is listed as being in satisfactory condition.

The maximum volume listed by DWR is 535 Acre-ft (174 MG). However, the Regional Water Quality Control Board, Central Valley Region requires two feet of freeboard, reducing its permitted capacity to 155 Mgal. The top area open for rainfall to enter the system is 21.6 acres. The bottom area is open for infiltration and groundwater is approximately 10 feet below the bottom of the effluent storage pond. The EPA Design Manual for Municipal Wastewater Stabilization Ponds10 provides a conservative estimate of seepage rate for percolation ponds of approximately 0.3 in/day. Through the model calibration against the 2017 Water Year, the seepage rate was adjusted to 0.4 in/day to more closely represent actual conditions. Throughout the wet year, treated wastewater enters the reservoir and is held until temperatures increase. Eventually that water is used at the LAAs or the Castle Oaks Golf Course through the Castle Oaks Water Recycling Plant.

4.3 Off Site Discharge to the Castle Oaks Water Recycling Plant In addition to discharging to on-site LAAs, the MCSP WWTP also has connection to the COWRP, which provides tertiary treated recycled water used for irrigation of the Castle Oaks Golf Course. There are two connections to COWRP, one is through Preston Reservoir and the Preston Outfall and the second is through a direct connection to the Preston Outfall located on the MCSP site consisting of piping and a bypass valve installed in 2017. Since the construction of the bypass valve in 2017, MCSP has delivered effluent directly through this pipeline, and has not sent any water to Preston Reservoir. The MCSP Effluent Storage Reservoir provides storage for MCSP WWTP effluent until it is discharged to either the on-site LAAs or the COWRP. Secondary disinfected effluent is conveyed to the COWRP based on an existing agreement among the Amador Regional Sanitation Authority (ARSA), CDCR, and the City of Ione, the Agreement to Regulate use of Henderson/Preston Wastewater Disposal System, or “Wastewater Agreement”. The Wastewater Agreement was first approved in September 2007 by the three parties.

This agreement specifies the amount of effluent that ARSA and CDCR have the right to convey for treatment at the COWRP.

The Wastewater Agreement was supplemented with the execution by the three parties of the 2009 lease for the storage and conveyance facilities utilized by ARSA. This agreement provides for an allowable total annual discharge of effluent by CDCR to COWRP of 350 acre-feet, which is counted against the allowable annual ARSA discharge of 650 acre-feet. Under the Wastewater Agreement, CDCR has had average monthly discharges as summarized in Table 8. The 2013 to 2024 average discharge volume excludes the water year 2023 distributions, which had uncharacteristically low discharges due to the accommodation of ARSA’s need for additional storage space due to reservoir storage repairs leading to atypical WWTP operations involving higher volume accumulation in the effluent storage reservoir throughout the wet season.

The historical average transfer to COWRP presented in Table 8 and the maximum allocations from the Tri Party Agreement were used as benchmarks in the water balance calculations, but the historical average discharge to COWRP was not used in the model scenarios. The waterbalance model scenarios utilized transfers to COWRP in two distinct ways: to demonstrate the need of COWRP transfers to maintain storage and capacity requirements, and to show the storage outcome under the maximized Tri Party Agreement allocation.

5.0 Water Balance Climatological Factors and Infiltration and Inflow Inputs The water balance was updated using data provided by MCSP over the current period of record and review of updated published climatological data summaries and statistics.

5.1 Rainfall Characteristics
The Desert Research Institute publishes tabulated average monthly precipitation for Camp Pardee from 1926 through 2024 and for CalFire Precipitation Station CF1 in Ione from 2012 through 2024. The average of these two monthly precipitation characteristics have been assumed for the MCSP site.

Long-duration depth-duration-frequency statistics were updated based on the most recent data from the Ione Station B00 4283 00 as maintained and published by the California Department of Water Resources, Flood Emergency Response Information Exchange, FERIX. For the 100 year hydrologic condition average monthly rainfall was multiplied by the ratio of the 100 year, 365-day storm to the average annual storm. This ratio is 1.81 and remains unchanged from previous iterations of water balance calculations for the site.

5.2 Soil, Crop, and Evapotranspiration Characteristics
Typical monthly evapotranspiration (ETo) rates were obtained from California Polytechnic State University Irrigation Training and Research Center (ITRC). MCSP falls within reference evapotranspiration Zone 14. Crop evapotranspiration and crop coefficients are available for both average year and wet year conditions. Crop coefficients were based on a representative mixture of pasture grasses and deciduous oaks (see Table 10 and 23 of the referenced document).11 The soil depth of the LAAs were assumed to be 14 inches for fields 1-4, and 6 and 60 inches for field 7. This is based on field observations. Soil Available Water Holding Capacity (AWHC) – or the total of available water in the root zone, and the Management Allowed Depletion (MAD) – or the amount of water that is allowed to be used by the plant between irrigations was estimated based on values as stated in the NRCS Web Soil Survey. The combination of the ETo, crop coefficients, and soil characteristics were used to estimate the amount of irrigation that each LAA could uptake on a monthly basis.

6.0 Water Balance Model Validation
The water balance was calibrated using available data from the 2017 water year, which had a reported annual total precipitation of over 41 inches, exceeding the 1-in-100 year precipitation season total for Ione, CA. Calibration of the water balance calculations were based on matching predicted peak effluent storage levels, end-of-season applications and remaining effluent as modeled in the water balance calculations with reported data. The following 2017 water year conditions were considered in the water balance calibration:
• Influent and effluent flow totals for the 2017 water year provided by MCSP and CDCR, • 1-in-100 year infiltration and inflow (included in the total influent flows), 11 California Crop and Soil Evapotranspiration, Cal Poly Irrigation Training and Research Center, ITRC Report No. R 03-001, January 2003.

• Actual ADWF of 0.38 Mgal/d, to establish a basis for model comparison at reported values; • Average monthly rainfall totals measured at the MCSP WWTP, • Recorded discharges to Preston reservoir, and
• Beginning effluent reservoir storage of 20 Mgal.

The ITRC Zone 14 Wet Year evapotranspiration and an adjusted evapotranspiration constant for grass and trees was referenced for consistency with modeled calculations. In effort to provide a basis for comparison between the modeled LAAs and the actual reported conditions, the AWHC between LAA7 and LAAs1-4 and 6 were analyzed separately. An adjustment factor was applied to the LAA application calculations to reflect modeled (calculated) vs. reported system conditions. The model provided full effluent storage disposal by the end of the water year, closely matching actual 1-in-100 year hydrologic conditions.

The reported storage values presented an effluent storage accumulation which peaked earlier than the simulated model; however, the modeled volume and rate of increase/decrease were consistent with the values provided by the calibration, justifying the model formulas and processes. A conservative percolation factor of 0.3 in/day was initially used to estimate the percolation losses. After adjustment, a percolation factor of 0.4 in/day was found to provide the disposal conditions that most accurately represent reported system conditions, with this percolation factor still being within a reasonable range. The catchment area runoff coefficient to the effluent storage reservoir was also adjusted from the original conservative assumption of rational runoff coefficient of 0.9 to 0.5 providing for a model result better reflecting recorded water storage conditions. The current adjustment assumes the reservoir water surface capture is 100%, the 0.5 rational runoff coefficient only applies to the embankment surrounding the reservoir. The value was reduced to a more reasonable level of 0.5 during calibration. Soil Survey classified the regional soils in the area around the MCSP Effluent Storage Reservoir and determined them to be heavy and roughly 80% steep and 20% flat; therefore, a reasonable range for embankment runoff coefficients was found to be 0.3 to 0.5.

As such the high end of this range is just fine, conservative. The 2017 1-in-100 year water balance calibration is provided in Exhibit D.

7.0 Water Balance Projections and Results
As required by the August 14, 2024 Water Code Section 13267 letter and further clarified by RWQCB staff, the following flow scenarios were evaluated with the water balance calculations under average year and 1-in-100 year precipitation conditions:

1. Under projected 5-year influent flow conditions, projected to 0.54 Mgal/d as presented in Table 6;

2. Under current permit capacity ADWF of 0.74 Mgal/d
In addition to these influent flow bases, a third scenario detailing the estimated maximum potential influent flow at a combined MCSP occupancy of 4,926 incarcerated persons, as presented in Table 6, has also been evaluated.

Disposal conditions assumed under each of these conditions include:
• Evaluation of potential or all effluent to be applied to existing LAAs. 154

• Need for and use of proposed 61 acres of new on-site LAAs. • Discharge to COWRP consistent with 2009 Agreement and recent historical discharges. • Discharge to some other off-site effluent disposal/recycled use location.

The water balance shows that the current system is capable of functioning in all but an extreme case. Conducted at the current annual average with a safety factor of 5% to account for seasonal variability, the water balance shows that the system is currently capable of functioning during both a normal wet weather season and 1-in-100 year season at an ADWF of 0.54 Mgal/d.

The MCSP system is also shown to be able to function to treat, dispose and store treated effluent at the 0. 74 Mgal/d design flow, however the water balance does show that the system would have an excess of water if forced to operate at the projected permit design flow during a 1-in-100 year precipitation weather season. Results of the water balance scenarios are discussed below and presented in Table 9 and discussed further in the below sub-sections.

The summaries below include details regarding multiple scenarios including and assumed transfer to COWRP consistent with the average transfers for the past ten years as presented in Table 8. This scenario is provided to allow for proper context to the interplay of seasonal storage to total disposal needs and the timing of when such disposal is available. Absent integrating proper context to the calculations, providing discharge volumes alone does not accurately depict the characteristics of facilities that could be required to meet capacity needs.

7.1 Average and 1-in-100 Year Precipitation Season at Average Recent Flows of 0.54 Mgal/d Under average conditions and current flows at no more than 0.54 Mgal/d, MCSP WWTP is able to treat and dispose of all seasonal flows through use of the existing on-site LAAs without exceeding the available maximum storage of 155 Mgal. The water balance predicts that the effluent storage reservoir would reach a maximum level of 86 Mgal by the end of April. The effluent generated through the duration of the water year would be accommodated by the existing LAAs leading to an ending storage reservoir balance of 18 Mgal.

Under 1-in-100 year precipitation season conditions, which adds substantial water to the reservoir and severely limits the availability and capacity of the LAAs, the effluent storage reservoir would reach a maximum level of approximately 125 Mgal, 30 Mgal below the facility capacity of 155 Mgal, by May. Once seasonal conditions allow application of effluent to the on-site LAAs, predicted to be no earlier than May, effluent would be applied to the maximum estimated capacity of these facilities throughout the irrigation season. At the end of the season an estimated 76 Mgal would remain in the effluent storage reservoir at the end of September. Utilizing a subsequent water balance calculation assuming an average year following the 1-in-100 year, the resultant following year effluent generation would exceed the capacity of the effluent storage reservoir by April. To remain within reservoir capacity throughout the year, the starting volume would need to less than 70 Mgal in the second year. Therefore, under current flow conditions additional storage and/or disposal capacity is needed. The water balance calculations contained in Exhibit D indicate the following:
• After expanding the on-site LAAs by 61 acres:
o Maximum storage is reduced to 121 Mgal by May.
o Effluent in storage is reduced to 50 Mgal by the end of September. o The calculations indicate that with the addition of the previously proposed 61 acres of LAA that the system may be able to accommodate wastewater flows, however with a risk of exceeding permitted effluent storage volumes with subsequent wet years.
• Utilizing the existing LAAs but discharging to the COWRP at 83 Mgal/year (lower than the historical rate of 93.8 Mgal):
o Maximum storage is reduced to 114 Mgal by May.
o Effluent in storage is reduced to 0 Mgal by the end of September. o The calculations indicate that using the COWRP discharge would result in the system being able to contain the 1-in-100 year conditions and subsequent average years without exceeding effluent storage capacity and being able to return to an empty reservoir by the end of the second year using only the onsite LAAs.

7.2 Average and 1-in-100 Year Precipitation Season at Permit Capacity Flow of 0.74 Mgal/d Under current permit flow limit conditions of 0.74 Mgal/d and average year precipitation conditions, MCSP WWTP is able to treat and dispose of all seasonal flows through use of the existing on-site LAAs without exceeding the available maximum storage of 157

155 Mgal. The water balance predicts that the effluent storage reservoir would reach a maximum level of 129 Mgal by the end of April, leading to an effluent storage of 85 Mgal by the end of the water year. Although flows under the first average year condition remain within capacity, an ending storage balance of 85 Mgal is expected to cause violations in a following average year.

Under 1-in-100 year precipitation season conditions the effluent storage reservoir would exceed its maximum capacity of 155 Mgal in April. If the effluent could be stored, once seasonal conditions allow application of effluent to the on-site LAAs, predicted to be no earlier than May, effluent would be applied to the maximum estimated capacity of these facilities throughout the irrigation season. At the end of the season, effluent storage needs would continue to exceed the capacity of the effluent storage reservoir through the end of July. Therefore, under current permit flow limit of 0.74 Mgal/d conditions additional storage and/or disposal capacity is needed. The water balance calculations contained in Exhibit D indicate the following:
• After expanding the on-site LAAs by 61 acres:
o Maximum effluent storage is exceeded in May.
o The calculations indicate that additional storage and/or disposal capacity would be needed. • Utilizing the existing LAAs but also discharging to the COWRP at 83 Mgal/year:
o Maximum effluent storage is still exceeded in May.
o The calculations indicate that additional storage and/or disposal capacity would be needed. • After expanding the LAAs and discharging to the COWRP at 350 ac-ft per year in accordance with the Tri Party Agreement:
o Maximum effluent storage is 126 Mgal in May.
o Effluent storage would be reduced to nearly empty in June. o The calculations indicate that the yearly effluent storage need is fully accommodated with the utilization of the CDCR allocation of 350 ac-ft per year discharge to COWRP.

Expanded storage and effluent disposal capacity is expected to be needed if the MCSP system is to operate independently at a permit capacity of 0.74 Mgal/d, beyond that provided by expanding the on-site LAAs or utilizing the COWRP discharge consistent with historical rates.

7.3 Average and 1-in-100 Year Precipitation Season at Maximum Capacity Flow of 0.67 Mgal/d The MCSP and MCIC maximum potential occupancy scenario condition is expected to generate 0.67 Mgal/d. In an average year rainfall condition, the water balance calculations indicate that the existing MCSP WWTP facilities have the capacity to dispose of all effluent flows within the 155 Mgal volume of the effluent storage reservoir. The peak volume contained within the effluent storage reservoir is estimated at 115 Mgal at the end of April. The effluent reservoir volume steadily decreases as land 158

application disposal is available by the end of March. In September, the remaining year end reservoir volume is 62 Mgal, which is anticipated to lead to an exceedance of storage reservoir volume in the following average year.

Under 1-in-100 year conditions, the maximum effluent storage reservoir volume of 155 Mgal is met by the end of May, therefore, the results of the water balance analysis indicate that additional effluent disposal is required. The water balance results for the maximum capacity ADWF condition provided in Exhibit D are summarized below:
• Expanding the on-site LAAs by 61 acres under a 1-in-100 year precipitation conditions:
o Maximum storage capacity is nearly met in May.
o The ending balance in the storage reservoir is 94 Mgal, which is expected to lead to an exceedance in storage volume in the following average year.
• Disposal to the existing LAAs with discharge to the COWRP at 83 Mgal/year under a 1-in-100 year precipitation conditions:
o Maximum effluent storage capacity is nearly met in May. o The ending balance in effluent reservoir storage is 41 Mgal in September. o The calculations indicate that the yearly effluent storage need is fully accommodated in following average precipitation years with starting storage volume of 41 Mgal. • After expanding the LAAs and discharging to the COWRP at 350 ac-ft per year in accordance with the Tri Party Agreement:
o Maximum effluent storage is 112 Mgal in May.
o Effluent storage would be emptied by the end of September. o The yearly effluent storage need is fully accommodated with the utilization of the CDCR allocation of 350 ac-ft per year discharge to COWRP.

If the MCSP system is to operate independently at a maximum population capacity flow of 0.67 Mgal/d, expanded storage and effluent disposal capacity is expected to be needed by at least what is provided by expanding the on-site LAAs by adding 61 acres of State lands or utilizing the COWRP discharge at historical rates.

8.0 Assessment of Needed Expanded Capacity
As is previously noted, the water balance shows that the current system is capable of functioning in all but the extreme cases.

With a safety factor of 5% to account for seasonal variability, the water balance shows that the system is currently capable of functioning during both a normal wet weather season and a 1-in-100 year precipitation season at an ADWF of 0.54 Mgal/d, 159

except during the year following the 1-in-100 precipitation year. The MCSP system, designed for daily wastewater treatment flow rate of 1.0 Mgal/d, can treat all expected higher flows.

However, the MCSP system cannot dispose and store treated effluent at the higher flows of 0.74 and 0.67 Mgal/day.

Subsequent years and, when combined with a 1-in-100 year precipitation inflow, compound the problem specifically in the permit capacity of 0.74 Mgal/d scenario. Adding storage alone will not relieve the additional flow contribution to the system. To address this, MCSP would have to increase LAA areas and/or storage to accommodate the larger events and subsequent events. The water balance model was run to conceptually establish to what extent MCSP needs additional storage capacity and/or LAA area to accommodate extreme events.

8.1 Conceptual Expansion With On and/or Offsite Facilities Based on the above-summarized water balance analysis, disposal and/or storage improvements would be necessary for MCSP to be in compliance with permit requirements under 0.54, 0.74, and 0.67 Mgal/d flows. The amount of excess volume for the three scenarios is shown in Table 10. The volume of excess is the overflow volume in the 1-in-100 season plus the difference between the volume of the end of the first year and the maximum allowable volume in the second year without causing or threatening to cause a effluent storage violation of the permit in the third year. The requirements for additional area for use as net LAA disposal, whether onsite or offsite, depends on the type of land available, especially the soils and geology. However, assuming characteristics similar to the existing MCSP LAAs 1-4, general conclusions can be made in quantifying the required area needed to accommodate the current influent flows, estimated maximum capacity flow rate and permitted maximum flow rate of 0.54 Mgal/d, 0.67 Mgal/day and 0.74 Mgal/day, respectively.

Under current influent flow and disposal conditions, 1-in-100 year precipitation flows are fully contained. However, in the average precipitation year following the 1-in-100 year precipitation conditions at current capacity ADWF of 0.54 Mgal, effluent storage capacity is exceeded in April with a starting storage volume of 76 Mgal. In the average year following a 1-in-100 precipitation year, a starting storage volume of 70 Mgal is the maximum volume to be accommodated in order to maintain compliance with the WDRs. Adding 61 net acres of additional LAA, equal to the area proposed in 2015, will relieve the problem, with the additional disposal area providing adequate disposal of effluent flows and remaining volume within the effluent storage reservoir at the year end.

Permit Capacity Flow of 0.74 Mgal/d
Under current disposal conditions, 1-in-100 year precipitation conditions, and permit capacity ADWF of 0.74 Mgal, effluent storage capacity is exceeded by April. Ending volume in the storage reservoir is estimated to be 144 Mgal. In an average year following a 1-in-100 precipitation year, a starting storage volume of 26 Mgal is the maximum volume to be accommodated to remain within storage capacity limits. The addition of 250 net acres of LAAs would lead to an ending storage balance of 36 Mgal, which is able to be processed within the next average year. Additional storage of at least 9 Mgal would also be needed to contain effluent flows through peak flow periods of the year.

Maximum Capacity Flow of 0.67 Mgal/d
Under current disposal limits and a 1-in-100 precipitation year condition, effluent storage is met in May and the year-end volume in reservoir storage is estimated to be 120 Mgal. This carryover into an average following year leads to consistent period of storage exceedance starting in December. The maximum beginning storage volume in year 2 would need to be reduced to 41 Mgal to remain within current storage capacity. The addition of a total of 163 net on or off-site acres would result in a year-end storage balance of 50 Mgal. With the additional land application area, all storage needs throughout the year would be met. With the addition of the 163 net acres of additional LAA areas, flows are also accommodated in an average year following a 1-in-100 precipitation year, including the starting effluent storage volume of 50 Mgal.

Tri-Party Agreement Maximum Discharge to COWRP at 350 Ac-ft/year As was previously noted above, in addition to discharging to on-site LAAs, the MCSP WWTP also has connection to the COWRP, which provides treated secondary water for use in making tertiary treated recycled water used for irrigation of the Castle Oaks Golf Course. This is based on an existing agreement among the ARSA, CDCR, and the City of Ione. This agreement provides for an allowable total annual discharge of effluent by CDCR to COWRP of 350 acre-feet, which is counted against the allowable annual ARSA discharge of 650 acre-feet.

A review of the historical use of this agreement shows that MCSP has not been taking full advantage of it, although has been using quite a bit of the agreement’s allowable use. In fact, full use of the agreement on the agreed monthly maximum increments provides a solution to capacity exceedances during peak storage accumulation points throughout the year by fully diverting effluent storage reservoir volumes to COWRP by June. If capacity were available, the use of the full CDCR allocation of the Wastewater Agreement would provide a viable option for additional disposal capacity needs in the Permit Capacity Flow and Maximum Capacity Flow scenarios under 0.74 and 0.67 Mgal/d ADWF respectively. 161

This Technical Memorandum (TM) provides the water balance that has been updated in response to the February 3, 2025, Central Valley Regional Water Quality Control Board (Water Board) Review of the Site-Specific Water Balance for the Amador Regional Sanitation Agency (ARSA) disposal system in joint operation with the Castle Oaks Water Reclamation Facility (COWRF) and the Castle Oaks Golf Course (COGC) which receive secondary disinfected effluent from the Sutter Creek Wastewater Treatment Plant (WWTP). This TM is organized into the following sections:
• Background Information
• WWTP Flow & Population Data
• Climatological Data
• Storage Facilities Characterization
• Disposal Facilities Characterization
• Water Balance Results
Background Information
The ARSA, City of Ione (City), and Portlock International Ltd. (Portlock) are all permittees under the State Water Resources Control Board (SWRCB) Water Reclamation Requirement Order 93- 240 (WRRs). The WRRs permit the ARSA system, the COWRF, and the COGC land application areas (LAAs). ARSA operates the storage and disposal facilities downstream of the Sutter Creek WWTP, however the City operates the COWRF and Portlock operates the COGC.

ARSA’s system includes conveyance infrastructure, three storage reservoirs and two LAAs. The system receives secondary disinfected effluent from the Sutter Creek WWTP and disposes of it on the Bower’s Ranch and Hoskin’s Ranch LAAs. Storage is provided in the ARSA system by the Henderson Reservoir, Preston Forebay and Preston Reservoir. Remaining effluent that is not disposed in the ARSA system is conveyed to the COWRF to receive tertiary treatment before it is disposed at the COGC. ARSA also owns a diversion from Sutter Creek that may divert surface water to meet irrigation demands when inadequate volume of Sutter Creek WWTP effluent is available. The Sutter Creek diversion is in need of repair and ARSA continues to seek cost effective bids for the work expected to occur in 2025 at the earliest.

Under a 2007 contractual agreement with the City, the California Department of Corrections and Rehabilitation (CDCR) Mule Creek State Prison (MCSP) has sent effluent to the COWRF either through Preston Reservoir or directly via an interconnection pipe. The discharge from MCSP to the COWRF is not described in the WRRs and is an agreement between ARSA, the City, and the CDCR. This agreement is the Parties’ effort to manage the system to the maximum benefit possible. The flow diagram of the interconnected system is illustrated in Figure 1. 267
