BID AWARD FOR ACTIVATED CARBON FOR THE WATER TREATMENT PLANT

DEPARTMENT
Utilities Department, Water

RECOMMENDATION
Request the City Council adopt Resolution No. 2025-108 (1) accepting the sole responsive bidder for the purchase of Activated Carbon; (2) authorizing the Director of Finance to execute a purchase order with Carbon Activated Corporation, the sole responsive bidder, to provide activated carbon to be used at the Water Treatment Plant, effective September 1, 2025 through June 30, 202 6, with the option to renew for an additional one-year period conditioned upon budget appropriations; and (3) authorizing the City Manager or their designee to approve any price increase for the one-year option to renew, conditioned upon budget appropriations.

Staff Recommendation: Approval (Utilities Department, Kyle Morgan, Interim Director of Utilities) Presenter: Reed Harlan, Assistant Director of Utilities/Water ESSENTIAL SERVICE – Yes, Keep City Clean for Public Health and Safety; Clean Water COUNCIL PRIORITY – Improve Public Safety

FISCAL ANALYSIS
The purchase order amount for treatment chemicals is estimated annual costs based on unit price and anticipated chemical usage. Quantities required by the Water Treatment Plant may fluctuate up or down during the purchase order period.

The purchase order price is firm for the first year. Any price increase under the contrac t renewal for subsequent years are subject to approval by City staff. Sufficient funds for the purchase of treatment chemicals are available in the operating budget of the Water Enterprise Funds.

PREVIOUS ACTION
None

19 Item5.

BACKGROUND
On July 21, 2025, request for bids to purchase Activated Carbon to be used at the Escondido-Vista Water Treatment Plant (“WTP”) were sent out to three prospective vendors. The request for bid contained detailed chemical specifications, estimated annual quantities, and a one -year fi rm price contract requirement for the period September 1, 2025 through June 30, 2026.

On July 31, 2025, one bid was received from Carbon Activated Corporation. No bids were received from General Carbon Corporation and Norman Fox & Co.

Powdered activated carbon (“PAC”) is employed for its high adsorptive capacity and effectiveness in the removal of geosmin, 2-methylisoborneol, and other taste and odor causing compounds that are otherwise difficult to treat with conventional chemical processes. These compound s frequently occur within the City’s raw water supply and require advanced treatment strategies to meet aesthetic water quality standards.

Additionally, PAC has demonstrated efficacy in the adsorption of perflourooctane sulfonic acid and in the reduction of total organic carbon levels, contributing to improved regulatory compliance, particularly with respect to disinfection byproduct precursor removal and emerging contaminant mitigation.

The current and continuing scope of work includes two sections of severely deteriorated trunk sewer main that are in critical condition. These sections are shown in Figure 1 below and defined as follows:

Section 1: Ash Street - paralleling the Escondido Creek, from the Firestone Complete Auto Care (“Firestone”) parking lot to the Walmart Neighborhood Market (“Walmart”) parking lot; and Section 2: Beech Street to Grape Day Park - paralleling the Escondido Creek, trave rsing a short section of North Hickory Street, then continuing in East Pennsylvania Street from North Hickory and extending into Grape Day Park.

Figure 1

Section 1 emergency repair work began on August 7, 2024. All repairs to Section 1 are now complete.

Section 2 emergency repair work began on July 25, 2024, and is anticipated to be complete by January 16, 2026. The contractor, CCL Contracting, Inc. (“CCL”), has installed approximately 3,720 linear feet of trunk main, from Grape Day Park to Hic kory Street, within Pennsylvania Avenue; north within Hickory Street from the intersection of Pennsylvania Avenue and Hickory Street to just south of the intersection of Hickory Street and Lansing Circle; easterly through the Westmont Assisted Living Commu nity; and continues easterly within the City’s Escondido Creek private property/public utility easement, paralleling the south side of Escondido Creek to Grape Street. The additional restoration work at Westmont Assisted Living Community, which included ab andonment and slurry fill of 2,000 feet of 21 -inch sewer, abandonment and slurry fill of 14 manholes, and repair of 40 feet of 21 -inch trunk sewer line within the bike path at Date Street, has been completed.

In June 2025, a construction conflict with a 36” diameter water transmission main along the bike path was identified. City staff determined that rerouting the sewer trunk main from the bike path into East 26 Item6.

Valley Parkway, provided the best value to the city from a cost, constructability , product longevity, and risk mitigation. Construction on North Fig Street, south of the channel bridge, between Washington Avenue and Valley Parkway, will tentatively start on September 2, 2025, with full closure for approximately three weeks and reopen t o the public on September 19, 2025. Construction on to East Valley Parkway between Beech Street and Fig Street, will tentatively start on September 16, 2025 with work occurring at night to minimize the impact to the community. Electronic message boards upd ating the community are in place, where appropriate, throughout the construction project site and will remain through the duration of work.

Utilities staff continues to communicate and coordinate with affected businesses and residents within the construction zone of influence, as well as other City Departments regarding current and upcoming construction, including the upcoming road closures.

BACKGROUND

The City of Escondido owns and operates a sanitary sewer system consisting of 370 miles of gravity mainline that conveys raw sewage to the Hale Avenue Resource Recovery Facility . Sewage and its associated wastewater spilled from a sanitary sewer system may threaten public heal th, beneficial uses of waters of the State, and the environment. The State Water Board adopted Statewide General Waste Discharge Requirements for Sanitary Sewer Systems in order to establish statewide standards and requirements for sewer system operations, the prevention of and reporting of spills from sanitary sewer systems.

The State Water Resource Control Board’s Statewide Sanitary Sewer Systems General Order No. 31 Item7.

2022-0103-DWQ ( “General Order”) requires the City to maintain a S anitary Sewer Management Plan (“SSMP”) that outlines a plan and schedule to: (1) properly manage, operate, and maintain all parts of the City’s sanitary sewer system; (2) reduce and prevent sanitary sewer spills ; and (3) contain and mitigate spills that do occur.

The General Order requires the City to update its SSMP every six years, present the updated plan to the City Council for approval, and upload and certify the approved plan to the State Water Resources Control Board’s online database, the California Integrated Water Quality System (“CIWQS”), by the City’s Legally Responsible Official, as defined in the General Order § 5.1.

In addition to updating the SSMP every six years, the City must perform internal audits of its SSMP at a minimum of once every three years, submit audit reports to the CIWQS Sanitary Sewer System Database, and continuously document changes to the SSMP in a change log during the period between formal SSMP updates.

1. SSMP GOAL AND INTRODUCTION

Overview - This SSMP element identifies the overall statewide goal established for SSMPs by the SWRCB and specific goals the City of Escondido has established in support of attaining this overarching state-wide goal. As required by SWRCB Order No. WQ 2022-0103-DWQ, the introduction element also (1) presents a historical overview of the City’s SSMP implementation and updates, (2) presents a schedule for implementing SSMP audits and updating the SSMP, and (3) summarizes the City’s sewer collection system assets and operations.

State Water Resources Control Board (SWRCB) Order No. WQ 2022-0103-DWQ. SWRCB Order No.

WQ 2022-0103-DWQ establishes statewide standards and requirements for sewer system operations and the prevention and reporting of spills from sanitary sewer systems. SWRCB Order No.

WQ 2022-0103-DWQ defines a sewer spill as:

A spill is a discharge of sewage from any portion of a sanitary sewer system due to a sanitary sewer system overflow, operational failure, and/or infrastructure failure.

Order No. WQ 2022-0103-DWQ requires the reporting of spills through a statewide electronic reporting system, and require sewer agencies to maintain and update SSMPs that address the following eleven elements, including:

1. Establishing the SSMP goal and, SSMP update schedule and summarizing sewer system assets.

2. Describing the SSMP organization structure.

3. Demonstrating legal authority to regulate the sewer system and sewer dischargers.

4. Describing the preventative operations and maintenance program.

5. Implementing and enforcing sewer design and performance provisions.

6. Implementing a Spill Emergency Response Plan.

7. Implementing a sewer pipe blockage control program.

8. Providing for adequate sewer system capacity and capital improvements.

9. Implementing an adaptive management program that assesses SSMP performance.

10. Performing periodic internal audits of SSMP effectiveness in preventing spills.

11. Implementing a communication program.

SSMP Goal. Order No. WQ 2022-0103-DWQ establishes the following overarching goal for SSMPs:

The Goal of the Sewer System Management Plan is to provide a plan and schedule to (1) properly manage, operate, and maintain all parts of the sanitary sewer system, (2) reduce and prevent spills, and (3) contain and mitigate spills that do occur.

Resolution No. 2025-103
Exhibit "A"

Page 9 of 102 ends

42 Item7.

To support attainment of this state-wide goal, the City of Escondido has established specific goals to minimize the potential for sewer spills and to reduce impacts from spills that do occur. These goals include:
• Properly manage, operate and maintain all portions of the City’s wastewater collection system. • Provide adequate capacity to convey peak flows.
• Reduce inflow and infiltration (I&I) into the sewer system through active inspection, dye testing and smoke testing.
• Reduce the potential for spills by maintaining the City’s program for sewer line video monitoring, root and debris removal, control of fats oils and grease (FOG), pipe replacement and maintenance/upgrades at wastewater pump stations.

1.1 Regulatory Context
Order No. WQ 2022-0103-DWQ requires that the SSMP introductory section include a description of the SSMP implementation history and SSMP updates.

Historical Overview. Order No. WQ 2022-0103-DWQ updated sewer system requirements originally established by SWRCB Order No. WQ 2006-0103-DWQ. The City’s original SSMP, approved by the City Council in 2009 after a public review period and public hearing, addressed requirements in Order No.

WQ 2006-0103-DWQ. The original 2009 SSMP brought together in a unified document a number of long-standing City of Escondido operations or programs directed toward preventing spills, including the City’s:
• Program of scheduled preventative inspection and maintenance of sewer mains and pump stations.
• Ongoing program for identifying sewer mains deemed to have an elevated risk for blockage from roots or grease, and providing increased frequency of inspection and cleaning of such mains.
• Program for maintaining and enforcing sewer design standards. • Spill emergency response program.
• Capital Improvements Program (CIP) and ongoing assessment of sewer system capacity and rehabilitation needs.

The SWRCB in 2013 adopted Order No. WQ-2013- 0058-EXEC which established revised statewide monitoring, reporting, and record keeping requirements for sewer spills. The SWRCB in September 2015 issued updated SSMP development guidance in A Guide for Developing and Updating Sewer System Management Plans (SSMPs).

Since that time, the City of Escondido Utilities Department has conducted regular reviews and audits of spill prevention performance and has periodically updated the SSMP to address needs. Updates to the City’s SSMP were adopted in 2014, 2017, 2018, 2020, 2021 and 2022. Each of these updates were conducted under requirements established in SWRCB Order No. 2006-0003-DWQ.

Resolution No. 2025-103
Exhibit "A"

Page 10 of 102 ends

43 Item7.

This 2025 SSMP update addresses requirements established in Order No. WQ 2022-0103-DWQ. As part of this update, each of the 11 elements of the City’s existing SSMP were evaluated for consistency with requirements of SWRCB Order No. WQ 2022-0103-DWQ. This updated SSMP incorporates changes to the City’s existing SSMP to address:
• Revised SSMP terminology and organizational requirements established within SWRCB Order No. WQ 2022-0103-DWQ.
• Upgrades to City of Escondido treatment and collection facilities along with updates to the City’s Capital Improvements Program.
• Changes and updates to the City’s Spill Emergency Response Plan. • Changes in City staffing and organizational structure.

While the appearance, terminology and organization of this updated SSMP has changed compared to the existing SSMP, each of the core elements of the City’s existing SSMP remain intact, and this 2025 SSMP update is deemed to not represent a significant program change compared to the 2022 SSMP.

1.2 SSMP Update Schedule
Order No. WQ 2022-0103-DWQ requires that the SSMP introductory section include a schedule for updating the SSMP and for conducting internal audits. Table 1-1 presents the City’s schedule for SSMP updates and for conducting internal audits.

SSMP Audits. The prior SWRCB Order No. 2006-0003-DWQ required that internal audits of the SSMP be conducted every two years and that the results of the audit be kept on file. SWRCB Order No.

WQ 2022-0103-DWQ requires that internal audits be conducted at a minimum frequency of three years, and that the audits be submitted to CIWQS within six months of the end of the 3 -year audit period. The most recent SSMP audit (conducted pursuant to Order No. WQ 2006-0003-DWQ) covered the period through the end of calendar year 2022. The first audit conducted under Order No. WQ 2022-0103-DWQ will cover calendar years 2023-2025 and will be submitted to CIWQS by July 1, 2026.

Table 1-1 summarizes key milestones for completing and submitting the required SSMP audit.

The wastewater collection system delivers wastewater to the Hale Avenue Resource Recovery Facility (HARRF), which is the terminal treatment facility for the City. HARRF also receives wastewater from the Rancho Bernardo portion of the City of San Diego, but all San Diego wastewater collection and conveyance facilities are addressed within the City of San Diego SSMP. HARRF provides secondary treatment for all incoming flows. HARRF secondary effluent not directed to the onsite HARRF tertiary treatment facility is discharged to the Escondido Land Outfall for conveyance to the San Elijo Ocean Outfall.

Figure 1-1 (page 1 -5) presents the overall location and layout of the City’s wastewater collection system. The City maintains an up- to-date GIS (geographical information system) map and asset management program of its sanitary sewer system, which depicts locations of gravity segments and manholes, pumping facilities, force mains, valves, and other appurtenances . In accordance with requirements of SWRCB Order No. WQ 2022-0103-DWQ, the City has uploaded a detailed map of its sanitary sewer collection system into CIWQS.

Table 1-3 (page 1-6) presents a breakdown of gravity mains and force mains that comprise the City’s wastewater collection system.

4.4 Equipment Inventory
The City utilizes asset management software to manage the maintenance and repair of the City's wastewater treatment and collection facilities and equipment. The asset management software identifies scheduled maintenance and repair activities, and is used to track repair/maintenance histories of equipment and pipelines. Section 3 of the City’s Spill Emergency Response Plan details equipment available to respond to spill reports.

As part of the Utilities Depart ment maintenance management program, management personnel evaluate inventory needs for critical components and spare parts. The City maintains an inventory of critical components which include (1) spare pipes sections and fittings, (2) spare parts, components, and fittings for pump stations, and (3) spares for repair and response equipment. Section 3 of the City’s Spill Emergency Response Plan summarizes critical components and parts typically maintained in the City's inventory. To update this inventory, Utilities Department management evaluate supplies, components, and equipment necessary to allow for simultaneous repairs in two locations. Critical components and spare parts are identified on the basis of:
• historic parts/components inventories and use patterns, • manufacturer's recommendations,
• design engineer recommendations,
• past failure history, likelihood of failure and risk associated with failure, • number of units in service requiring the parts/components, • operating experience and recommendations from field crews, • preventative maintenance schedules,
• parts/components availability from suppliers and time required to receive delivery, • cost (including delivery cost),
• parts/components availability from adjoining agencies, and • contingency/portable equipment needs.

Inter-Agency Communication . The Utilities Department maintains informal communications with adjoining sewer agencies. Should the need arise, through this communication the City can arrange for spill response resources that may be available from adjoining agencies. Further, Utilities Department managers maintain a list of suppliers for critical components, along with anticipated emergency delivery times.

7. SEWER PIPE BLOCKAGE

CONTROL PROGRAM

Overview - The City maintains a public outreach program that promotes proper disposal of fats, oils, and grease (FOG) by industry, commercial establishments, and residential users. The City maintains the legal authority to establish, monitor, and enforce FOG - and debris-related prohibitions, discharge limits, and treatment requirements. The City requires installation and use of grease and oil interceptors or other applicable pretreatment for FOG generators and requires dischargers to properly dispose of or recycle FOG. The City has identified sewer main reaches that have an elevated risk of FOG - or debris-related blockage and has implemented accelerated inspection and maintenance schedules within these reaches to minimize the potential for sewer spills.

Requirements. Provision 7 of SWRCB Order No. WQ 2013-0103-DWQ requires sewer agencies to determine if a sewer blockage program is required to control fats, oils and grease (FOG), rags and debris, If a program is needed procedures must include:
• An implementation plan and schedule for a public education outreach program that promotes proper disposal of pipe-blocking substances.
• A plan and schedule for the disposal of pipe-blocking substances generated within the sanitary sewer system service area.
• The legal authority to prohibit discharges to the system and identify measures to prevent Spills and blockages.
• Requirements to install grease removal devices (such as traps or interceptors), design standards for the removal devices, maintenance requirements, best management practices (BMP) requirements, record keeping and reporting requirements. • Authority to inspect grease-producing facilities, enforcement authorities, and whether the Enrollee has sufficient staff to inspect and enforce the FOG ordinance. • Identification of sanitary sewer section s subject to FOG blockages, and establishment of a cleaning and maintenance schedule for sewers with an elevated blockage risk. • Implementation of source control measures for all sources of FOG reaching the sanitary sewer system.

Overview of Sewer Blockage Control. The City's Municipal Code establishes prohibitions against sewer line blockages, and establishes requirements governing the discharge of FOG or pipe-blocking debris. The Municipal Code also provides the City with authority to:

Resolution No. 2025-103
Exhibit "A"

Page 37 of 102 ends

70 Item7.
• evaluate and regulate the discharge of substances (including FOG) which may lead to sewer line blockage,
• develop and implement required pretreatment facilities and design standards, and enforce discharger compliance with the standards,
• inspect FOG generating facilities and enforce compliance with FOG limits established within or pursuant to the Municipal Code,
• remove or prevent planting of vegetation that block or adversely impact the ability of sewer mains to convey wastewater, and/or
• take other actions necessary to prevent the potential for sewer main blockage.

As part of the City's FOG program, the Wastewater Division conducts video inspections of all sewer mains and maintains a database of FOG -related blockages, grease buildups, and required sewer cleanings. On the basis of this information, the City designates sewer main reaches that are considered to have an increased risk of FOG -related blockage. For such at -risk sections, the City conducts an increased frequency of sewer main cleaning and video monitoring.

Public Education Program. The City has developed and implemented a public education outreach program to promote proper disposal of FOG, enhance public awareness of FOG issues, promote proper recycling of oil and grease, and identify other key household or commercial causes of sewer pipe blockages. Key elements of the City's public outreach program include (1) a program to educate commercial and residential users, and (2) an outreach program directed toward proper handling of waste automotive oil.

The City's outreach to commercial and residential users includes web- based and printed education literature on FOG issues, proper FOG disposal, and FOG best management practices (BMPs ). The literature is posted on the City's website (escondido.gov/482/Commercial) and highlights the fact that grease is the most common cause of pipe blockages. The education literature stresses such household BMPs such as:
• not flushing wet wipes or feminine products into the sewer, • solidifying household cooking oils and grease and placing the solidified grease into sealed containers for disposal with solid waste,
• scraping leftover food and grease into the trash,
• wiping grease from cooking pans with paper towels prior to washing, and disposing of the paper towels with solid waste,
• the need for periodic inspection/maintenance of private sewer laterals, and • the need to call the City before cleaning private laterals so the City can remove any debris that is pushed into the public sewer line from cleaning the lateral.

The City also maintains a public outreach program (o nline at: Escondido.gov/693/Used-Oil-Recycling) that is directed toward educating the public on proper disposal and recycling of automotive oil. This outreach program addresses proper procedures for waste oil recycling and facilities where automotive oil can be returned for recycling. Additionally, waste oil recycling signs and information are posted at participating oil recycling facilities.

Disposal of Pipe-Blocking Substances. Rags and debris removed from City of Escondido sewer mains are disposed of in a landfill. BMPs established by the City for household and commercial disposal of collected grease include disposal via grease recycling facilities or disposal in solid waste co llection facilities.

Legal Authority. As discussed within Element 3 of this SSMP, Section 22 -37 of the Municipal Code prohibits the discharge of FOG or other substances which may cause stoppage or blockage of sewer lines. Sections 22 -38 and 22-39 of the Municipal Code establishes requirements governing the installation and maintenance of FOG removal devices, and establishes the authority of the Director of Utilities to promulgate rules, regulations and requirements regarding FOG discharges and required FOG treatment. Section 22-203 of the Municipal Code provides the Director of Utilities with powers to establish and enforce best management practices and pollution prevention practices.

Grease Removal Requirements. Pursuant to authority established in the Municipal Code, the City requires pretreatment for the removal of FOG. Grease control devices (grease interceptors or grease traps) are required for food establishments or facilities with kitchen equipment that have the potential to produce grease. The City also requires grease/oil interceptors or separators for automotive or other maintenance facilities designated by the City as representing a threat for the discharge of grease or oils.

Additionally, the City has implemented a series of BMPs for handling grease at food establishments.

The BMPs address:
• grease interceptor maintenance,
• grease storage facilities,
• cleaning, and
• kitchen management BMPs.

Authority to Inspect and Enforce FOG Compliance . The Municipal Code establishes the City's authority to inspect FOG dischargers and enforce FOG limits. Section s 22-20 and 22 -189 of the Municipal Code provide the City with right to entry and the authority to inspect and monitor sewer users to ensure compliance with applicable discharge standards, discharge permit standards, local limits, and sewer discharge regulations. Sections 22 -10, 22-11 and 22 -192 of the Municipal Code provide the City with authority to enforce compliance with:
• discharge prohibitions, standards, and requirements established within the Municipal Code, and
• discharge policies, design standards, and other requirements established by the City pursuant to authorities established within the Municipal Code.

FOG Source Control Measures. The City’s approved pretreatment program regulates industrial discharges through the issuance of sewer use permits. Regulated industries or establishments include:
dischargers subject to pretreatment requirements governing:
• Categorical Industrial Users (CIUs) subject to federal category -specific pretreatment requirements,
• industries under federal regulations that are subject to regulation as Significant Industrial Users (SIUs), and
Resolution No. 2025-103
Exhibit "A"

Page 39 of 102 ends

72 Item7.
• dischargers (such as food service and automotive dischargers ) who are not subject to federal regulation as CIUs or SIUs but are regulated by the City in accordance with provisions established in the City's Municipal Code.

Food establishments and automotive or repair facilities that may generate grease and oil are routinely inspected by City pretreatment staff for conformance with applicable pretreatment and FOG control regulations. The City’s Environmental Compliance Super visor (under the direction of the Director of Utilities and Assistant Director of Utilities/Wastewater) is responsible for coordinating and implementing pretreatment and FOG-related inspections and enforcement actions.

Sewer System Segments Susceptible to FOG Blockage. Measures implemented by the City of Escondido to prevent sewer system blockages includes:
• a program of regularly scheduled visual inspections of manholes, • a program of regularly scheduled television video inspections of sewer mains, • maintaining a database of observed instances of root damage and observed instances of FOG- related problems identified through the inspections,
• maintaining a database of past spill events,
• collecting and analyzing data from the City’s SCADA system and from SmartCover monitoring systems,
• evaluating each reach of the City's sewer collection system and identifying sewer main reaches that are determined to represent an increased risk for FOG -related blockages or blockages related to vegetation or tree roots,
• periodically updating of the evaluation of sewer line reaches to assess the risk of FOG -related or root-related sewer main blockages,
• reviewing and evaluating building and license applications form food services establishments who are applying for new discharge permits or changes of use for existing businesses, and • conducting regular inspections of food establishment records for FOG pumping frequency.

For areas deemed to have an elevated risk of FOG -related or root -related blockages, the City implements quarterly sewer cleaning operations and conducts video inspections whenever blockage risk issues are identified or suspected. Based on results from video inspections and/or trending data from SmartCover manhole monitors, the City may also schedule more frequent cleaning of sewer reaches that have an elevated potential for blockage . For sewer mains that do not have an elevated risk of blockages, the City implements a program that targets completing video inspections on 35 miles of sewer mains per year.

Where warranted the City may also implement special studies to identify FOG sources, identify and evaluate potential means of FOG controls, or identify facilities improvements required to minimize the potential for FOG-related blockages.

Overview of City of Escondido Condition Assessment Procedures. The City of Escondido employs a multi-level series of procedures to assess and monitor conditions of sewer collection assets. This series of assessment procedures implements best practices and technologies available, and includes; • A system of regularly scheduled field inspections, assessments and sewer cleanings. • A system of regularly scheduled video inspections.
• Annual assessment of environmental risk factors to determine if any sewer segments warrant more frequent cleanings or inspections due to environmental risks. • Scheduled (annual or more frequent) re -evaluation of sewer segment risk categories that is based on prior visual and video inspection records, spill history, the potential for grease blockage, the potential for root-damage, the age and life expectancy of sewer collection assets and environmental risk factors.
• Updating inspection, maintenance or CIP schedules to reflect assessment findings.

Scheduled Field Assessment and Sewer Cleaning. Throughout the year, the City maintains a scheduled series of (1) visual inspections of manholes and sewers mains, and (2) physical cleanings of sewer collection mains. Cleaning is conducted either using mechanical (e.g., rodding or bucketing) or hydraulic processes (e.g., jetting, flushing, balling or pigging). Inspections include visual inspections which may be supplemented by video inspections.

To support this ongoing inspection and sewer cleaning effort, the City maintains a list of “at risk” sewer collection assets that may be prone to grease blockages , root damage or failure. This “at risk” list is developed on the basis of (1) potential sources of damage/blockage, such as presence of upstream restaurants or presence of trees near the sewer mains, (2) past history of inspections, maintenance activities and input from field staff, and (3) environmental factors.

For sewer segments deemed to have an elevated risk of blockages , damage, pipe failure or environmental consequences, the City implements a quarterly cleaning and inspection schedule. This schedule results in 100 percent of the “at risk” sections being inspected and cleaned each year.

Historical City inspection records and spill assessments have determined that this quarterly cleaning and inspection schedule for “at risk” segments is appropriate for addressing blockage concerns. More frequent cleanings of “at risk” segments are inefficient (e.g., cleaning an already clean pipe) as grease, debris and roots have not had time to amass to the point where cleaning is worthwhile. Less frequent cleanings may make it more difficult for crews to clean pipes and may elevate the potential for spills.

For sewer segments not deemed to represent an elevated risk of grease blockage, root damage, failure, or environmental consequence, the City maintains a once-every-two-years cleaning and maintenance schedule. In areas deemed to not present an elevated risk for blockage or failure, this results in 50 percent of the City’s collection system being cleaned each year. Historical City inspection records and spill assessments show that this biannual cleaning and inspection schedule for sewer segments not deemed to represent an elevated risk is appropriate for addressing blockage concerns. More frequent cleanings in sewer segments with no elevated risk are inefficient, and less frequent cleanings may make it more difficult for crews to clean pipes and may elevate the potential for spills.

Immediate or Emergency Assessments. As part of these scheduled sewer main cleanings and inspections, the City immediately schedules repair activities or emergency sewer assessments if the need is evident. Field inspection reports and notes filed by field personnel are reviewed by City supervisors (under the direction of the Wastewater Operations Manager and the Wastewater Collections Supervisor) on a monthly or more frequent basis to determine if any individual sewer segment:
• should be elevated to a higher risk category and a more frequent inspection/cleaning schedule due to (1) findings of field crews during inspections/cleanings, (2) past history of blockage or capacity issues, or (3) past history of other system deficiencies, • warrants further immediate assessment to determine if the segment needs further repairs , rehabilitation or replacement,
• warrants priority elevation within the City’s CIP schedule for sewer main rehabilitation or replacement, or
• represents a higher level of human or environmental consequences due to collapse, failure, blockage, capacity or other vulnerabilities.

In addition to the above monthly reviews of field inspection reports and records, City staff meet on an annual basis to assess if changes are required to the City’s list of “at risk” sewer segments that warrant more frequent inspections and cleanings. This annual assessment of “at risk” segments is to consider prior visual and video inspection records, spill history, the potential for grease blockage, the potential for root-damage, the age and life expectancy of sewer collection assets and environmental risk factors.

Recordkeeping. The City maintains daily records of sewer main inspections and cleaning activities. The Wastewater Collections Supervisor is responsible for maintaining records of sewer inspection and cleaning activities. The Wastewater Collections Supervisor is also responsible for reporting findings and recommendations to the Assistant Director of Utilities/Wastewater for consideration and action.

Results of annual City staff reviews of “at risk” sewer segments and environmental risk factors are to be memorialized in a memorandum that is to be kept on file and made available for regulator review upon request.

Regularly Scheduled Video Inspection. In addition to the scheduled series of inspection and cleanings, the City maintains a scheduled series of video inspections of sewer mains. For areas not deemed to present an elevated risk for blockage or failure, the City follows a schedule of video monitoring each non-risk sewer segment at a frequency ranging from 5 to 10 years. This 5 to 10 year frequency is common within Southern California sewer agencies of similar size to the City of Escondido. To support this frequency, the City schedules a minimum of 35 miles of video monitoring per year for sewer segments deemed to not represent an elevated risk of blockage or failure. This translates into a minimum of ten percent of the City’s sewer collection system being video inspected each year.

Significantly more frequent video monitoring is conducted on sewer segments deemed to represent an elevated risk of sewer blockage or environmental consequence. As noted, regular sewer cleanings of such segments are conducted on a quarterly basis. Video monitoring may be utilized to supplement the quarterly inspection/cleaning operations. Scheduling of video monitoring for at -risk segments within the City’s collection system varies depending on the results of the quarterly inspection/cleaning operations. In general, the City follows schedule for video monitoring (to supplement cleaning) for “at Resolution No. 2025-103
Exhibit "A"

76 Item7.
risk” sewer mains at a frequency of 1-2 years (annual for highest risk segments and biannual for segments deemed to represent an elevated risk). The City of Escondido annual or biannual video frequency for “at risk” segments is consistent with video frequencies employed for “at risk” segments within other Southern California sewer agencies.

Sewer video monitoring is conducted by City personnel, but the City reserves the right to utilize outside monitoring assistance if required. When combined with the above-described biannual visual inspection and cleaning schedule, this video monitoring schedule provides the City with a robust system for warning of any irregularities in sewer collection system assets.

Recordkeeping and Responsibilities. The City maintains daily records of sewer main video inspections.

The Wastewater Collections Supervisor is responsible for maintaining records of these video inspections and for reporting findings and recommendations to the Assistant Director of Utilities/Wastewater for consideration and action.

Annual Assessment of Environmental Risk Factors. A significant majority of the City’s sewer collection system exists within the Escondido basin which is bisected by Escondido Creek. Gravity sewers within this basin convey flows from the northern and southern portion of the Escondido Creek basin toward a major trunk sewer that parallels the creek and discharges to HARRF.

Escondido Creek is channelized throughout almost all of the City and the potential for erosion-related damage is minimal. Additionally, City crews have ready access to the channel, and the channelization (in times of lower creek flows) enhances the ability of City crews to respond to, contain and recover spilled flows. While these conditions may mitigate against spill impacts, the City designates facilities immediately adjacent to (or under) Escondido Creek as a higher priority facility because:
• Escondido Creek flows are virtually year -round, and the potential exists for spills that reach the creek channel to be carried downstream for greater distances before containment can be achieved.
• The lower 26-miles of Escondido Creek are listed as being Clean Water Act Section 303(d) impaired for indicator bacteria.
• The potential for sewer spills may be higher during extreme wet weather conditions when Escondido Creek flows would be highest and containment/recovery would be most difficult.

The Escondido basin is relatively flat, and the City does not have any sewer collection facilities that represent additional failure risk due to steep terrain. Additionally, past inspection results do not indicate any facilities that involve an increased risk due to high groundwater.

Outside the Escondido basin, the City of Escondido maintains a number of collection facilities that are tributary to Lake Hodges. Most collection facilities in this area are newer, have a history of excellent performance, and have a history of no problems being reported as part of scheduled inspection, cleaning and video evaluations. Additionally, since no City of Escondido sewer collection facilities are located immediately adjacent to the reservoir and the sewer collection facilities are readily accessible to City staff, distance provides an added element of safety in responding to facilities failures, containing spills and recovering spills. For this reason, City sewer collection facilities in areas tributary to Lake Hodges do not at present receive higher environmental priority than other portions of the City’s collection system.

Resolution No. 2025-103
Exhibit "A"

77 Item7.

The Assistant Director of Utilities/Wastewater (with support of the Wastewater Collections Supervisor) is responsible for annually assessing , re -evaluating and updating environmental risk factors and assigned risk categories. Factors to be considered as part of this annual assessment include:
• Information from prior sewer spill reports and “ postmortem” assessments of past spill response actions.
• Information from scheduled or emergency maintenance/cleaning/inspection reports or video monitoring.
• Input received from field staff, regulators or the public. • Results from annual SSMP audits.
• Updated information on site conditions that may increase the potential for sewer failure, such as the potential for soil erosion, earth movement or landslides, soil that presents an increased risk for corrosion, or a high groundwater table.
• Updated information on conditions that may represent the potential for increase environmental risk, such as updated 303(d) listings, updated environmental information, or changes in actual or designated beneficial uses.
• Updated information on how spill response actions may be adversely influenced by terrain, high groundwater, site access or public access.

As part of this assessment, City supervisors may modify the City’s list of “elevated risk” segments to incorporate additional sewer segments deemed to represent elevated risk on the basis of the above environmental criteria.

Recordkeeping and Responsibilities. The Assistant Director of Utilities/Wastewater is responsible for maintaining records related to the City’s assessment of environmental factors in prioritizing spill risks.

Condition Assessment Prioritization. City staff (under the direction of the Director of Utilities) are to annually review the inspection and cleaning assessments, video assessments, sewer main risk category assessments, environmental risk factors and other available information to determine if revision is required in:
• Designation of “at risk” sewer system segments (including designations based on environmental risk factors).
• Sewer inspection, maintenance or video monitoring priorities. • Schedules for inspection, cleaning and maintenance of City sewer collection facilities. • Schedules for video monitoring of sewer main integrity. • CIP schedules for sewer system facilities replacement or rehabilitation.

Recordkeeping and Responsibilities . The Wastewater Collections Supervisor is responsible for maintaining and updating records regarding designated “at risk” sewer segments . The Wastewater Collections Supervisor is also responsible for updating schedules for inspecting and cleaning sewer segments, and schedules for video monitoring of sewer segments. The Assistant Director of Utilities/Wastewater is responsible for coordinating with the Director of Utilities to address recommended CIP revisions.

Climate Change Considerations. Initial assessment of the City’s sewer collection system to climate change vulnerabilities show no near-term climate-change concerns. No City sewer collection facilities are at risk due to rising sea levels. Additionally, existing sewer pump stations and above-ground sewer collection facilities are adequately protected from flood and runoff challenges associated with current and near-term weather patterns. (See current Federal Emergency Management Agency flood maps at FEMA.gov/portal.) Further, existing sewer collection facilities are adequately protected from wildfires and power outages.

While the near-term climate -change risk to City of Escondido sewer collection infrastructure is presently minor, overall risks to City sewer collection facilities could change in future years. The City of Escondido Climate Action Plan (2021) notes that, while no significant changes in long-term annual average precipitation may occur, the number and intensity of extreme wet-weather events are likely to change. Such a change in extreme wet weather events can:
• Create direct risks due to expansion of flood zones.
• Create indirect risks as a result of increased interruptions of electrical power. • Create direct risks associated with wildfires.
• Create indirect risks as a result of increased I&I and related impacts on sewer system capacity.

Section 8.2 presents procedures the City implements to address potential sewer system capacity issues that may be affected by climate change.

Recordkeeping and Responsibilities. The Director of Utilities is responsible for annually assessing State of California climate change projections and determining whether or when City -specific climate - change related studies are required to reassess direct or indirect vulnerabilities of existing or planned City of Escondido sewer collection facilities to changes in climate.

Annual Assessment of Adequacy of Existing Plans. The Utilities Director (with input from City staff) will annually determine if any of the above-described conditions warrant update or revision of:
• the City’s sewer master plan,
• sewer flow monitoring or modeling studies,
• the City’s SSMP, or
• the City’s SERP.

Recordkeeping and Responsibilities . The Director of Utilities (with input from Utilities Department staff) is responsible for determining whether updates are required in the City’s Wastewater Master Plan, sewer flow monitoring/modeling studies, SSMP or SERP. This determination shall be made on the basis of a review of:
• data from sewer inspection, cleaning and video monitoring, • sewer spill reports, causes, response actions and environmental consequences, • environmental risk factors,
• climate change considerations, and
• input from field staff, supervisory staff and regulators, environmental

8.2 Capacity Assessment and Design Criteria
Capacity Assessment Requirements. SWRCB Order No. WQ 2022-0103-DWQ requires the following capacity assessment requirements for SSMPs:

The Plan must include procedures to identify system components that are experiencing or contributing to spills caused by hydraulic deficiency and/or limited capacity, including procedures to identify the appropriate hydraulic capacity of key system elements for:
• Dry-weather peak flow conditions that cause or contributes to spill events; • The appropriate design storm(s) or wet weather events that causes or contributes to spill events; • The capacity of key system components; and
• Identify the major sources that contribute to the peak flows associated with sewer spills.

The capacity assessment must consider:
• Data from existing system condition assessments, system inspections, system audits, spill history, and other available information;
• Capacity of flood-prone systems subject to increased infiltration and inflow, under normal local and regional storm conditions;
• Capacity of systems subject to increased infiltration and inflow due to larger and/or higher-intensity storm events as a result of climate change;
• Increases of erosive forces in canyons and streams near underground and above-ground system components due to larger and/or higher-intensity storm events;
Resolution No. 2025-103
Exhibit "A"

Page 47 of 102 ends

80 Item7.
• Capacity of major system elements to accommodate dry weather peak flow conditions, and updated design storm and wet weather events; and
• Necessary redundancy in pumping and storage capacities.

In accordance with these requirements, t he City of Escondido 's sewer system is designed and constructed to provide adequate capacity to handle anticipated average and peak wastewater flows.

Master Plan Evaluation of Flows. The sewer service area tributary to HARRF consists of multiple topographic drainage areas. P rojections for peak ultimate wastewater flows within each of the drainage areas has been developed within the City's Wastewater Master Plan . Peak ultimate wastewater flows are projected in the Wastewater Master Plan on the basis of buildout of zoned lands, observed wastewater flow generation rates, projected sewers connections (or conversions from onsite septic), and observed peak flow factors. Wastewater facilities needs, wastewater flow monitoring, and wastewater flow projections presented in the City's Wastewater Master Plan (last updated in 2012) remain valid and conservative, as:
• A significant majority of the sewer service area of Escondido was already built out in 2012. • Zoning and designated land use densities have remained largely as they were in 2012. • Unit flow generation values within the City's service area are trending lower than projected in 2012 due to increased water conservation.

Flow Estimation Criteria and Procedures. The City of Escondido maintains appropriate design criteria for estimating wastewater flows and designing and constructing wastewater collection facilities.

Consistent with the procedural requirements of SWRCB Order No. WQ 2022 -0103-DWQ, capacity modeling presented in the Wastewater Master Plan utilized input data from flow meters and manhole “smart covers” in which water level data are transferred via telemetry. Observed data from flow meters and “smart covers” were used to characterize flow within the City, as follows:
• Dry weather unit flow contribution of 55 gallons per capita per day (gpcd) for residents, apportioned by population with each sub-area of the HARRF tributary sewer system. • Dry weather unit flow contribution of 38 gpcd for the employment population, apportioned by population within each sub-area of the sewer system tributary to HARRF. • Diurnal flow variations based on observed data from each sub-area of the sewer system. • I&I contributions of 4800 gallons per mile of sewer gravity main. • Storm flow peaking factor of 2.17.

The flow projections presented in the Wastewater Master Plan remain valid and are consistent with the required procedures itemized in SWRCB Order NO. WQ 2022-0103-DWQ. The Wastewater Master Plan projected a HARRF inflow of more than 13.5 mgd for calendar year 2025. Actual 2025 HARRF flows have been trending approximately 10 percent below this value. This difference is largely attributed to water conservation measures implemented by residents and business and a slightly slower-than-projected development r ate. Additionally, observed peak flows remain consistent with the peaking factors utilized in the 2012 Wastewater Master Plan.

With an additional margin of safety provided these factors, the City's 2012 Wastewater Master Plan continues to provide Utilities Department managers with a useful tool for assessing wastewater Resolution No. 2025-103

collection facilities needs for ultimate projected wastewater flows. Consequently, no changes in the City's average and peak flow generation standards are required at this time.

Design Criteria and Procedures . The City's sewer design criteria and design procedures are in accordance with sewer slope, depth of flow, velocity and size criteria set forth in standard sewer design manuals and handbooks developed by professional organizations. The City's sewer design criteria are also in accordance with the normal standard of practice in use within Southern California. Additionally, the criteria have been vetted as part of sewer flow projections and modeling work conducted within the City's Wastewater Master Plan. Further, operations experience of the City's wastewater collection facilities does not indicate any deficiencies within the City's sewer sizing or design criteria.

Procedures to Identify Capacity Limitations . SWRCB Order No. WQ 2022-0103-DWQ requires that SSMPs include:

Procedures to identify system components that are experiencing or contributing to spills caused by hydraulic de ficiency and/or limited capacity, including procedures to identify the appropriate hydraulic capacity of key system elements for:
• Dry-weather peak flow conditions that cause or contributes to spill events; • The appropriate design storm(s) or wet weather events that causes or contributes to spill events; • The capacity of key system components; and
• Identify {sic] the major sources that contribute to the peak flows associated with sewer spills.

Wastewater Master Plan Capacity Evaluations . As documented above, the City of Escondido Wastewater Master Plan remains valid for addressing hydraulic capacity of pump stations, force mains and sewer mains. Further, facility upgrades identified in the Wastewater Master Plan to address capacity deficiencies have been implemented. As a result, no existing City of Escondido collection facilities are “contributing to spills caused by hydraulic deficiency and/or limited capacity.” Further, capacity analysis modeling presented in the Wastewater Master Plan indicate no near-term potential for such “hydraulic deficiencies” in sewer collection facilities. Consistent with the procedure requirements established in SWRCB Order No. WQ 2022 -0103-DWQ, the Wastewater Master Plan compared existing capacities of each City of Escondido pump station, force main and gravity main with required capacities as determined on the basis of computer modeling of the City’s existing collection system using input data that addressed:
• existing condition assessments,
• rated capacities of existing facilities,
• monitoring data from flow meter, and
• monitoring data from “smart cover” manhole covers.

In accordance with these assessment and capacity evaluation procedures, the Wastewater Master Plan identified 16 pipeline projects and three pump stations that required upgrades, replacement, or rehabilitation. The City is currently in the final phase of a three-phase plan to implement the projects recommended in the Wastewater Master Plan. As part of this program, the City has completed the all pump station projects recommended in the Wastewater Master Plan . In addition to addressing capacity issues, the pump station improvements ensure adequate facility redundancy in pumps, motors and electrical power.

The City has also completed all pipeline work addressed in the Wastewater Master Plan to ensure adequate hydraulic capacity of gravity mains and force mains. Additionally, the City has completed almost all pipeline upgrades recommended in the Wastewater Master Plan to address estimated life Resolution No. 2025-103
Exhibit "A"

Page 49 of 102 ends

82 Item7.
cycles of pipe materials. The City has also implemented upgrades trunk sewer upgrades that have eliminated the need for several of the City’s former wastewater lift stations.

During the past decade, the pipeline upgrade program presented in the Wastewater Master Plan has resulted in approximately 20 percent (over 70 miles) of the City’s existing sewer pipe being replaced or rehabilitated. With these completed capital improvements, sewer main and pump station facilities within each of the tributary areas are capable of handling projected peak ultimate wastewater flows.

Procedures to Confirm or Update Capacity Assessments. While the capacity assessments and procedures presented in the Wastewater Master Plan remain valid, updated capacity assessments will be required at some point in the future. As documented in Section 8.1, one of the City’s annual “condition assessment” tasks is to evaluate whether the following information presented in the Wastewater Master Plan remains valid:
• Flow monitoring results and flow estimating procedures. • Computer model flow modeling and capacity assessments both under dry weather and storm conditions.
• Condition assessments of existing wastewater collection facilities. • CIP recommendations related to facility conditions or capacity.

In assessing whether any of the above Wastewater Master Plan criteria require update, the Director of Utilities will consider the following:
• data from existing system condition assessments,
• data from existing system inspections,
• results of SSMP audits,
• data from prior spill reports,
• spill experience from nearby sewer agencies,
• input from field staff, regulators and the public,
• potential means of reducing I&I through locked manhole covers, • potential means for reducing I&I by conducting additional smoke testing, • climate-change considerations, including effects of climate change on I&I, • potential effects of climate change on erosion and land stability in canyons and swales, and potential effects on above-ground and below-ground facilities, and • necessary redundancy in pumping and storage capacities.

If the Director of Utilities determines that update of the City’s sewer master plan is required, the updated master plan will address each of the above elements. Additionally, the capacity assessment presented in the updated master plan will include sewer system hydraulic modeling that will evaluate the capacity of each sewer collection asset. Flow data used within the model will be based on:
• updated sewer system flow monitoring data to characterize flows through each of the sub- areas that contribute to HARRF,
• assessments of infiltration into gravity mains and areas of high groundwater tables, • assessments of storm-related infiltration into gravity mains in flood prone areas, • assessments of storm-related inflow into gravity mains in flood prone areas, and Resolution No. 2025-103
Exhibit "A"

Page 50 of 102 ends

83 Item7.
• capacity of major system elements to accommodate dry weather peak flow conditions, and updated design storm and wet weather events.

Recordkeeping and Responsibilities . The Director of Utilities (with assistance from the Assistant Director of Utilities/Wastewater) is responsible for annually determining whether the capacity assessments presented in the Wastewater Master Plan remain valid. If an update is required, the Director of Utilities (or his/her designee) is responsible for supervising the effort to update the master plan and capacity assessment criteria and procedures.

Procedures for I&I Assessment. As noted above, I&I can significantly affect both dry weather and wet- weather sewer flows. Inflow to the sewer system is the more significant factor that influences peak flows, as inflow volumes can be both instantaneous and high, resulting in short-term peak flows that are substantially higher than average flows. Recognizing this effect, the City has for the past two decades embarked on an I&I reduction program that involves smoke testing, site inspection and public education. Through this effort, the City has identified and eliminated numerous illegal connections to the sewer system from parking lots, patios and roofs.

The City also determined that manholes can be a significant factor in influencing inflow, particularly in poorly drained or low-lying areas where members of the public may illegally open manhole covers to drain flood waters and protect their property. To address this issue, the City has installed sealed and locking manhole covers in low-elevation areas where short-term flooding has historically occurred.

While the combination of smoke testing and sealed/locking manhole covers has reduced overall I& I within the City’s collection system, the City’s ongoing I&I reduction program includes:
• Conducting inspection of manholes and video monitoring of gravity sewers to identify areas of potential I&I.
• A smoke testing program to identify illegal sewer connections. • Inspecting and (where required) replac ing conventional manhole covers with sealed and/or locked covers.
• Installing epoxy lining in manholes where I&I has been observed. • Implementing sewer main improvements, such as installing cured-in-place pipelines in sewer mains where I&I has been observed.
• Conducting inspections of the City’s more than 1600 commercial or industrial sites. • Installing rain val ves at facilities with outdoor sewer drains to prevent surface runoff from entering the sanitary sewer system during precipitation events. • Educating the public on what should not be connected to the sanitary sewer system.

Recordkeeping and Responsibilities. The Director of Utilities (or designee) is responsible for annually assessing I&I information and reports and determining whether (1) revisions in the City’s I&I program are warranted and (2) additional I&I monitoring or studies are required.

Capacity Assessment Procedures for Escondido Land Outfall. As noted, the above capacity assessments demonstrate that the City has provided adequate capacity in pump stations, force mains and gravity mains that comprise the sanitary sewer collection system tributary to HARRF.

Resolution No. 2025-103
Exhibit "A"

Page 51 of 102 ends

84 Item7.

Downstream from HARRF, however, capacity limitations exist within the Escondido Land Outfall (ELO), which conveys treated HARRF effluent to the San Elijo Ocean Outfall (SEOO). The ELO is not part of the sanitary sewer collection system tributary to HARRF that is regulated under SWRCB Order No.

WQ2022-0103-DWQ. As a result, releases of treated effluent from the ELO are not reported as “spills” under Order No. WQ 2022-0103-DWQ. It should be noted, however, that the City has implemented a number of improvements over the past decade to ensure that ELO capacity is not exceeded. These improvements include:
• Increasing wastewater storage capacity at HARRF.
• Expanding storage capacity within the City’s non-potable reuse system. • Implementing a program of reducing volumes of wastewater and recycled water stored in the City‘s non-potable reservoirs to provide additional storage capacity during wet weather events.
• Diverting a portion of the HARRF effluent flows to available onsite or offsite storage locations during wet weather events.
• Implementing the City of Escondido Membrane Filtration/Reverse Osmosis (MFRO) facility and associated improvements which allows the diversion of up to 2 mgd of HARRF recycled water to the MFRO facility during wet weather events.
• Maintaining the ability to direct approximately 1 mgd of HARRF recycled water to the cooling towers of the 500 megawatt Palomar Energy Center during wet weather events. • Coordinating with the City of San Diego to regulate discharges of the City of San Diego Pump Station 77 to HARRF under wet weather events.
• Connecting the HARRF SCADA system with the San Elijo Joint Powers Authority (SEJPA) San Elijo Water Campus (SEWC) to share flow and pressure data and coordinate City and SEJPA discharges to the SEOO.
• Establishing conservative SCADA pressure monitoring set points to provide SEJPA and City staff with increased lead time in responding to ELO/SEOO flow and pressure issues. • Coordinating with the SEJPA to remain alert to predicted weather conditions and develop and implement a coordinated “game plan” of proposed actions to monitor and deal with projected wet weather flows.
• Coordinating with SEJPA to maintain hourly telephone communications during the precipitation event to review conditions and plan for the upcoming hours.

Under the direction of the Director of Utilities, City staff continue to explore options (including increasing wet-weather storage capacities and increasing wet-weather uses for HARRF recycled water) for managing wet -weather flows and ensuring that HARRF discharge flows to the ELO remain within the ELO allowable hydraulic capacity of 21.4 mgd.

Summary of Capacity Assessment Procedures and Responsibilities. Table 8-2 (page 8-13) summarizes key procedures implemented by the City to comply with capacity assessment provisions of SWRCB Order No. WQ 2022-0103-DWQ.

As noted, current City of Escondido wastewater flows are tracking close to or slightly below flows projected in the Wastewater Master Plan. In conjunction with collection system upgrades (including equipment upgrades at lift stations and replacement of several key sewer mains), all capacity -related enhancement recommendations presented in the Wastewater Master Plan have been implemented.

Trunk sewers and sewer mains within the HARRF service area have adequate capacity to handle projected ultimate peak flows, and all pump stations are capable of handling projected peak flows with one pump out of service. No additional capacity enhancement measures are required in order to meet projected ultimate peak flow demands

A While the ELO is not part of the City of Escondido sanitary sewer system regulated under SWRCB Order No. WQ 2022 -0103-DWQ, the Director of Utilities (or designee) annually reviews ELO flows and performance and determines if additional studies or actions are required to address ELO capacity issues.

As noted above, the City has implemented condition assessments and capacity evaluation procedures consistent with requirements of Order No. WQ 2022-0103-DWQ. As part of the condition and capacity assessments, Utilities Department staff (under the direction of the Director of Utilities) annually assesses capacity and rehabilitation/replacement and maintenance needs and priorities. Utilities Department managers also continually assess the potential for changed conditions (e.g. changes in wastewater flows, new development or sewer users , peak flow timing, infiltration and inflow trends) that may require re-evaluation of system flows and facilities capacity needs.

If these ongoing evaluations indicate the potential for peak wastewater flows in excess of those addressed in the existing master plan, Utilities D epartment management will take actions to update the master plan and update facilities needs to reflect the changes in wastewater flow trends.

Rehabilitation and Replacement Plan. Utilities Department supervisors identify and prioritize long - term facilities improvements to lessen the potential for spills . As part of this prioritization process, Utilities D epartment management review existing facilities capacities and performance, existing wastewater flows and flow projections, master planning documents, and input from field personnel.

In assessing replacement and rehabilitation needs and priorities, the Utilities D epartment management considers:
• prior master planning analyses and recommendations,
• the age of existing structures and facilities,
• the rated capacity of existing facilities,
• the age, condition, and anticipated life-span of equipment and controls, • observed peak flows and projected peak flows,
• anticipated future capacity needs,
• construction materials used in the existing facilities and the anticipated longevity of the materials,
• the observed internal and external condition of sewer collection facilities, • soil conditions (including corrosion potential or soil movement potential), • the potential for erosion,
• access considerations, materials availability, and the potential difficulty of repair in the event of failure of the facility,
• previous operations and maintenance problems, past operating history, or past failures or breaks,
• reserve capacity and equipment and existing reliability provisions, and • the location of facilities, watercourses that could be affected by failure and potential for spill- related impacts.

8.4 C apital Improvement Program (CIP)
CIP Evaluations. The City develops and annually updates a Capital Improvements Program (CIP) to plan and budget for capital improvement projects in the upcoming five years. As part of the annual CIP review, Utilities Department managers identify and prioritize long -term facilities improvements, including sewer main and lift station improvements. These improvements include upgrades to address condition issues (e.g., condition, age and reliability) and upgrades to address capacity issues (e.g., changes in flows or changes in capacity ratings). On the basis of these evaluations, Utilities Department management each year:
• identifies and evaluates new facilities needs, rehabilitation needs, and facility replacement needs,
• reevaluates CIP needs identified or planned during prior years, and • develops an updated prioritization list and recommended schedule of CIP projects for the upcoming year and the subsequent five-year planning window.

CIP recommendations developed by the Utilities Department are submitted by the Utilities Director to the City Manager for review and approval prior to presentation to the City Council. The approved CIP Resolution No. 2025-103
Exhibit "A"

Page 54 of 102 ends

87 Item7.
is used by the City in establishing budget and funding needs for the City's wastewater operations. CIP costs include costs for planning, design, construction, and construction inspection.

Because existing wastewater collection facilities are sized to handle peak ultimate wastewater flows, no long-term or short -term capacity-related capital improvements within the City's sewer collection system are required. Instead, the City’s CIP in recent years has focused on facilities rehabilitation and maintenance and equipment replacement or repair.

Project Schedules and Funding for Wastewater -Related CIP Projects. The current CIP develops budgets for projects to be initiated during the planning period 2025 -2029. The City’s 2025/29 CIP is available online at Escondido.gov/187/Capital-Improvement-Program.

Within the 2025/29 CIP, wastewater and stormwater-related projects include:
• Stormwater infrastructure cleaning and trash screens ($10.66 million). • HARRF digester maintenance, including inspection, grit and sediment removal ($3.51 million). • Wastewater lift station maintenance, including repair/replacement of pumps, motors, control systems at each of the City’s sewer collection wastewater stations ($1.12 million). • Manhole rehabilitation, including lining, shelf repair/replacement and ring assembly raising ($1.61 million).

Funding for each of these projects for 2025-2029 is provided through the City’s Wastewater Utilities Capital Project Fund.

Facilities Adequacy. While ongoing maintenance of City wastewater collection facilities will be required (as described in the 2025/29 CIP), all major trunk lines, all tributary trunk lines, and all pump stations within each of the City's tributary drainage areas maintain adequate capacity to handle peak ultimate wastewater flows. With the completed facilities improvements, no capacity -related shortcomings currently exist within the City's collection system. As noted, the City maintains a margin of safety in assuring adequate capacity, as observed wastewater flows continue to trend at or slightly lower than flows projected within the City’s Wastewater Master Plan.

The City monitors a number of performance parameters in order to assess the effectiveness of the SSMP. From this monitoring, Utilities Department staff identify causes of sewer spills , and evaluate the effectiveness of spill detection and response procedures. Results from the performance monitoring are also used to determine how the SSMP elements may be modified to limit the potential for future spills.

Requirements. Provision 9 of Attachment D to SWRCB Order No. WQ 2022-0103-DWQ requires that the SSMP include an adaptive management section that addresses the effectiveness of the SSMP and identifies means for SSMP improvement, including:
• Maintaining relevant information, including audit findings, to establish and prioritize appropriate SSMP activities.
• Monitoring the implementation and measuring the effectiveness of each SSMP element. • Assessing the success of the preventative maintenance activities. • Updating SSMP procedures and activities, as appropriate, based on results of monitoring and performance evaluations.
• Identifying and illustrating spill trends, including spill frequency, locations , and estimated volumes.

SSMP Monitoring Program. The City of Escondido's SSMP complies with monitoring and measurement provisions of SWRCB Order No. WQ 2022-0103-DWQ, and utilizes the collected monitoring information to, in part:
• measure the effectiveness of sewer spill prevention actions, • assess SSMP prioritization needs,
• identify the sources/causes of sewer spills,
• evaluate preventative maintenance needs,
• evaluate CIP and rehabilitation/replacement needs,
• evaluate spill detection and response needs, and
• determine how SSMP elements may be modified to further limit the potential for the occurrence of sewer spills.

The Wastewater Division of the Utilities Department maintains records and reports of all sewer spills that occur within the City’s service area, including information documenting:
• the spill location,
• the cause or causes of the spill,
• the amount of sewage spilled and amount contained/recovered, • means of spill detection,
• duration of the spill,
• response actions and cleanup and restoration actions, • reports made to regulatory authorities, and
• measures implemented to prevent recurrence.

The Utilities Department maintains records of all spill reports filed with the SWRCB and Regional Water Quality Control Board (RWQCB), along with original monitoring instrument recordings, service call records, work orders, and spill response actions. The Utilities Department also maintains activity records that document performance and implementation measures, including preventative inspections and maintenance of pump stations, inspections and cleaning of sewer mains, and inspections and maintenance of sewer collection facilities. As part of these activity records, the City maintains records on:
• inspection findings,
• preventative maintenance or repair actions taken,
• field crew notes and recommendations,
• pump station logs,
• future inspection needs and preventative maintenance actions required, • customer complaints/notifications and City responses, and • needs for additional information, testing, analysis or data management.

Record Keeping Responsibilities. Under the direction of the Assistant Director of Utilities/Wastewater, the Wastewater Operations Manager is responsible for maintaining records of sewer spills and sewer main inspection, repair, and maintenance. The Wastewater Maintenance Manager is responsible for maintaining records on pump station operations, inspections, repair, and maintenance.

Monitoring Performance Parameters . Table 9 -1 (page 9 -3) summarizes monitoring performance parameters used to assess SSMP effectiveness. In assessing SSMP effectiveness, Utilities D epartment managers evaluate trends in the number, location, cause, and the volume of spills. Other monitoring performance parameters assess the effectiveness of spill detection and response actions. In total, the monitoring parameters allow the City to evaluate performance and improvement needs relative to:
• regulation of sewer discharges, including control of fats, oils and grease, • operation and maintenance,
• design and performance provisions,
• emergency response actions,
• system capacity,
• infiltration/inflow prevention, and/or

Evaluation Schedule. As set forth in Element 10 of this SSMP, triannual audits will be conducted to evaluate SSMP effectiveness. Because a relatively low number of sewer spills occur within the City, a sufficiently robust database may not be available as part of the triannual audits to allow for formal statistical evaluation or correlation of spill data. In this event, Utilities Department managers will review available data to determine if any spill trends are identifiable and will determine whether modification of SSMP elements are required.

Assessing Needs for SSMP Modifications. The Assistant Director of Utilities/Wastewater, with support from Wastewater Division management staff, is responsible for evaluating spill monitoring and performance parameters to assess SSMP effectiveness, identify spill sources and trends, and identify required changes in spill preventative measures, and required SSMP modifications. The Assistant Director of Utilities/Wastewater, in consultation with the Director of Utilities, will also be responsible for determining if outside contractor assistance is required to support the evaluation of SSMP monitoring performance parameters.

Evaluation of Preventative Maintenance Needs. Spill monitoring data will be used to identify required improvements in preventative inspection, cleaning and maintenance schedules. Table 9 -2 (page 9-5) summarizes available preventative responses should the City's SSMP monitoring indicate potential spill trends related to oil and grease, vandalism, pump station operation, and other causes.

Evaluation of Response/Detection Needs . Spill monitoring data may also be used to assess the effectiveness of spill detection and response. The Assistant Director of Utilities/Wastewater (or his/her designee) will assess monitoring parameters to evaluate the potential for improvement in spill detection or response, and to determine which strategies or improvements may be most effective in improving spill detection or response.

INTRODUCTION

1.1 Regulation of Sewer System Overflows and Spills
Overview City of Escondido Wastewater Operations. The City of Escondido sanitary sewer collection system covers a significant majority of the incorporated area of the City of Escondido. The collection system includes approximately 380 miles of sewer mains and 11 wastewater pumping stations. The City’s Hale Avenue Resource Recovery Facility (HARRF) serves as the terminal treatment facility for the collection system. HARRF treats all incoming flows to produce secondary effluent, and a portion of the secondary effluent is directed to onsite tertiary treatment facilities where disinfected tertiary recycled water is produced for distribution to recycled water (non-potable) customers. Excess HARRF secondary effluent is discharged to the 14-mile-long Escondido Land Outfall (ELO) for conveyance to the San Elijo Ocean Outfall. In addition to operating and maintaining the City’s wastewater collection system, the Wastewater Division of the Utilities Department operates and maintains the ELO.

Sewer System Management Requirements. City of Escondido wastewater collection operations are regulated under State Water Resources Control Board (SWRCB) Order No. WQ 2022 -0103-DWQ. 1 Order
No. WQ 2022-0103-DWQ establishes state-wide requirements governing sewer collection system operations, management, performance, reporting and notification. The requirements of Order No.

WQ 2022-0103-DWQ are directed toward minimizing the potential for spills from sewer facilities. Order No. WQ 2022-0103-DWQ defines a sewer system spill (also known as a sanitary sewer overflow) as a discharge of sewage from any portion of a sanitary sewer system due to a sanitary sewer system overflow, operational failure, or infrastructure failure.
2 Order No. WQ 2022-0103-DWQ prohibits spills, requires the reporting of spills through a statewide electronic 3 reporting system, and requires sewer agencies to maintain and update Sewer System Management Plans (SSMPs).

In accordance with SWRCB requirements, the City of Escondido maintains an SSMP that details the systems, operations, and procedures the City has implemented to prevent spills from the City’s sewer collection facilities. The City’s current SSMP was updated in 2025. 4 1 SWRCB Order No. WQ 2022-0103-DWQ was adopted by the SWRCB on December 6, 2022 and became effective on June 5, 2023. Order No. WQ 2022-0103-DWQ supersedes SWRCB Order WQ 2006-0003-DWQ (as amended by Order No. WQ 2013-0058-EXEC) which had previously regulated spills from sanitary sewer systems. 2 Definition of a spill is presented within Attachment A to Order No. WQ 2022-0103-DWQ. Exfiltration of sewage is not considered a spill under Order No. WQ 2022-0103-DWQ, provided that the exfiltrated sewage remains subsurface and does not reach a surface water. 3 California Integrated Water Quality System (CIWQS).
4 SWRCB Order No. WQ 2022-0103-DWQ requires SSMPs for cities larger than a population of 100,000 to be updated by May 2, 2025, and updated thereafter on a six-year basis.

Spill Emergency Response Plan (SERP) Requirements. Order No. WQ 2022-0103-DWQ requires the City to maintain and update a Spill Emergency Response Plan (SERP) that details measures to respond to spills in a timely manner, protect public health and the environment and to terminate, intercept, recover, and clean up sewage spills. Order No. WQ 2022-0103-DWQ requires that SERPs identify sewer agency measures and procedures to:
• Notify primary responders, appropriate local officials, and appropriate regulatory agencies of a spill in a timely manner.
• Notify other potentially affected entities (for example, health agencies, water suppliers, etc.) of spills that potentially affect public health or reach waters of the State. • Comply with the notification, monitoring, and reporting requirements of SWRCB Order No.

WQ 2022-0103-DWQ, state laws and regulations, and applicable RWQCB Orders. • Ensure that appropriate staff and contractors implement the SERP and that responding spill staff and contractors are appropriately trained.
• Address emergency system operations, traffic control and other necessary response activities. • Contain the spill and prevent/minimize discharge to waters of the State or any drainage conveyance system.
• Minimize and remediate public health impacts and adverse impacts on beneficial uses of waters of the State.
• Remove sewage from the storm drainage conveyance system. • Clean the spill area and drainage conveyance system in a manner that does not inadvertently impact beneficial uses in the receiving waters.
• Implement technologies, practices, equipment, and interagency coordination to expedite spill containment and recovery.
• Implement pre-planned coordination and collaboration with storm drain agencies and other utility agencies/departments prior, during, and after a spill event.

1.2 Purpose of Spill Emergency Response Plan

Chapter 2

SPILL DETECTION

2.1 Overview of Wastewater Collection System
The City of Escondido wastewater collection service area covers approximately 37.5 square miles. The sewer tributary area to HARRF consists of multiple topographic drainage areas and is serviced by 11 wastewater lift stations.

The City maintains an updated atlas that details all sewer collection system facilities. The sewer system atlas shows the location of gravity mains, manholes, force mains, and other facilities. A master electronic version of the City's sewer system atlas is maintained on the City's computer network, and copies are backed up regularly. C opies of the sewer system atlas are carried on City response vehicles.

Spill Prevention. As part of its SSMP, the City has developed and implemented an action plan to minimize the potential for spills. This action plan includes procedures regarding inspection, preventative maintenance, system operations, public education, capital improvements, monitoring and reporting, forensic assessment, and system audits.

2.2 Potential Spill Sources and Methods of Detection
As part of developing its SSMP, Utilities Department staff assessed prior spills, shared information with other regional agencies, evaluated historic and potential sewer spill causes, and researched state -wide spill reports to identify potential causes of spills. Potential causes of sewer spills within the City's sewer system include:
• Sewer gravity main breaks or failures.
• Sewer gravity main blockages.
• Sewer gravity main surcharging.
• Pressure main rupture.
• Pump station pump/motor/control failure.
• Pump station electrical failure.
• Pump station surcharging.

Gravity Sewer Main Breaks. Spills may be caused by failure (breaks) in gravity sewer mains. Potential causes of gravity sewer main failure may include:
• Penetrating tree roots.
• Corrosion
Resolution No. 2025-103
Exhibit "A"

Page 74 of 102 ends

107
Item7.
• Pipe wall or pipe joint failure.
• Inadequate sewer main installation/construction.
• Construction excavation activities.
• Earth slides or earth movement.

Spills resulting from sewer main breaks would result in either wastewater overflowing from the manhole immediately upstream from the break or wastewater flowing to the surface at or downstream from the point of the break. Virtually all City of Escondido gravity mains are located in City streets. As a result, spills resulting from sewer main breaks are likely to be quickly noticed by the public or personnel within other City of Escondido Departments. Utilities Department personnel also monitor for break -related spills through (1) flow monitoring data generated by SmartCover manhole monitoring systems, (2) flows and pump station performance data monitored via the City’s SCADA (Supervisory Control and Data Acquisition) system, and (3) flow data generated at the HARRF.

Gravity Sewer Main Blockages. The potential exists for spills to occur as a result of blockages or clogs within gravity sewer mains or manhole structures. Such blockages or clogs could be caused by :
• Penetrating roots through pipe joints or pipe walls.
• Penetrating roots through connections with private service laterals. • Grease or other congealing or viscous substances.
• Rags, paper, plastic bags, or other semi-solid debris. • Solid material or debris.
• Pipe wall failure.
• Vandalism.

Spills resulting from sewer main blockages or clogs would result in wastewater overflowing from the manhole immediately upstream from the blockage. Virtually all City of Escondido gravity mains are in City streets in highly-visible areas. As a result, visual inspection of City wastewater facilities by Utilities Department staff represents a key means of detection for blockage-related spills.

Spills resulting from sewer main blockages are likely to be quickly noticed by the public or personnel within other City of Escondido d epartments. As noted above, the Utilities Department also monitor s for blockage-related spills through flow monitoring telemetry data generated at SmartCover manholes, wastewater pump stations and at the HARRF.

Gravity Sewer Main Surcharging. As documented in the City's SSMP, scheduled City of Escondido Utilities D epartment capital improvements have kept pace with development and wastewater flows within the City of Escondido . As a result, no City of Escondido sewer mains are at risk for surcharge - related spills during dry weather. Sewer mains are also sized to handle maximum anticipated wet-weather wastewater flows plus infiltration and inflow (I&I).

Spills resulting from sewer main surcharges would result in wastewater overflowing from manholes. As noted, virtually all City of Escondido gravity mains are located in City streets in highly-visible areas. Visual inspection of City wastewater facilities by Utilities Department staff and reports from the public or other City of Escondido departments thus represents a key means of detecting surcharge-related spills.

Resolution No. 2025-103
Exhibit "A"

Page 75 of 102 ends

108
Item7.

The Utilities Department also monitors for surcharge-related spills through flow monitoring telemetry generated at wastewater pump stations and HARRF . Additionally, many of the key gravity mains are equipped with telemetered manhole covers which provide City staff with real-time monitoring data on flows and water levels in manholes and provide alerts to City staff when conditions of unusual flow or water levels are detected.

Pressure Main Ruptures . The potential exists for spills to occur as a result of pressure main ruptures.

Pressure main ruptures could be caused by:
• Corrosion.
• Pipe wall failure or joint failure.
• Inadequate installation/construction.
• Pressure build-up from blockages.
• Construction excavation activities.
• Earth movement.

Spills resulting from pressure main breaks would result from pressurized wastewater breaking the ground surface in the immediate vicinity of the pressure main break. Most City of Escondido pressure mains are located along roads or in areas with high foot and/or vehicle traffic, pressure main breaks would be visually recognizable. In addition to being highly visible, pressure main breaks would be detectable through flow rate and pumping pressure telemetry data from pump stations or at the HARRF. As a result, pressure main ruptures would typically be rapidly detected.

ELO spills should also be quickly detected. At the downstream end of the ELO, the City ’s SCADA system allows HARRF operators to monitor flow and pressure data at the structure where ELO flow joins SEJPA flow. This allows the City to detect pressure or flow discrepancies between the HARRF (upstream) and SEJPA (downstream) metering stations that may be indicative of a spill or potential spill from the ELO or appurtenant structures.

Pump Station Pump/Motor/Control Failure. To minimize the potential for spills caused by pump station pump or motor failures, each of the Cit y's wastewater pump stations is equipped with multiple pump/motors, with at least one pump/motor combination being on standby for use in the event of failure or maintenance of any of the other pump/motor combinations. To minimize the potential for spills resulting from failure of pump station controls, all City of Escondido pump stations are connected to the City’s SCADA system which allows for remote monitoring of pump station pumps, motors, pr essures, flows, wet well water levels, and alarms.

For a spill to occur as a result of pump station pump, motor, or control failure, such failure would have to be comprehensive and affect multiple pumping units and control systems. Spills resulting from such a comprehensive failure would be detectable to City crews through pump station alarms and remotely accessed pump station performance data. Additionally, all City of Escondido pump stations are located in highly-visible areas, and visual reports of the spill would be quickly noted by Utilities Department staff, other City of Escondido personnel, or the public.

Pump Station Electrical Outages. Each of the City's eleven wastewater pump stations are equipped with standby power generators that automatically actuate in the event of power failure.

Resolution No. 2025-103
Exhibit "A"

Page 76 of 102 ends

109
Item7.

With the presence of emergency onsite generators at the City's wastewater pump stations, a power failure spill could not occur unless failure of an onsite emergency power generator occurred simultaneously with failure of the local electrical power grid. To minimize the potential for such an occurrence, Wastewater Division crews routinely perform scheduled checks of onsite emergency power generating equipment, and routinely exercise the emergency power generators to ensure that they are in proper working order.

The City also maintains portable emergency power generators for use in the event of failure of any of the onsite pump station generators.

Simultaneous failure of the power grid and emergency generators would be rapidly detectable to City crews through pump station alarms and remotely accessed pump station performance data. As a result, it is probable that Utilities Department crews would be alerted to the power failure in advance of occurrence of any spill. Additionally, all City of Escondido pump stations are sited in highly-visible areas, and visual reports of any spill would be quickly noted by Utilities Department staff, other City of Escondido personnel, or the public.

Pump Station Surcharging. Major upgrades to several of the City 's wastewater pumping stations have been completed in recent years, and scheduled City of Escondido Utilities Department capital improvements have kept pace with anticipated future development and projected wastewater flows. As a result, risks associated with surcharge-related spills are minimized. Spills caused by pump station surcharging would be expected to occur only during times of comprehensive system failure during wet weather periods (such as the rupture of a gravity main or flood-related inflow into manholes).

Spills resulting from pump station surcharges would result in wastewater overflowing from the pump station, and would be instantly detectable to City crews through pump station alarms and remotely accessed pump station performance data. Additionally, since City of Escondido pump stations are sited in highly-visible areas, visual reports of any such surcharge-related spill would be quickly noted by Utilities Department staff, other City of Escondido personnel, or the public.

2.3 Target Response Times
Figure 2-1 (page 2-5) presents the City's spill response chain of command. The public can report spills on the City’s Public Works hotline, which is monitored from 6:30 am-4 pm on Monday through Thursday and 6:30 am to 3 pm on Fridays. Spill reports after hours received by Police Dispatch are routed to on-call Utilities Department response staff. Public reports of spills may also be received via the City’s ReportIt! mobile telephone engagement platform.

Spills Reported During Business Hours. Spill reports received during business hours are instantly forwarded to the Wastewater Collections Supervisor , Wastewater Operations Manager and Assistant Director of Utilities/Wastewater. The Wastewater Collections Supervisor is responsible for organizing and mobilizing work crews. On days or times the Wastewater Collections Supervisor is for some reason unavailable, the Wastewater Operations Manager shall designate an alternate person as being on call and responsible for organizing and mobilizing response crews.

Item7.

It is the City of Escondido's goal to respond as rapidly as possible to reports of spills or threatened spills.

Response times for Utilities Department staff to reach spill sites will vary by location, day of the week, and time of day. Utilities Department work/inspection crews are routinely on patrol within the City during business hours, and cell phone or radio communications are used to identify the location of available personnel. During business hours, depending upon location, the nearest crew may b e able to arrive on the scene of a reported spill site within a matter of a few minutes after the spill report is first received.

If no crew is in the immediate area of the spill, Wastewater Division management can immediately mobilize a response crew from onsite staff or staff engaged in offsite activities. Because of the central location of the w astewater collections system equipment, maximum travel time to the farthest reaches of the City is approximately 20 minutes. Typical response times to the four largest wastewater pumping stations (Lift Stations LS-1, LS-2, LS-3 and LS-4) ranges from approximately 5 to 15 minutes.

Spills Reported During Non-Business Hours. During non-business hours (night times, weekends, and holidays), the Wastewater Collections Supervisor schedules an emergency response crew as being on call and available to respond to spill reports. Spill reports during non- business hours are instantly forwarded via cell phone to the collections system stand-by staff, who immediately notify the Wastewater Collections Supervisor and the standby response team. After notifying the Wastewater Collections Supervisor, staff also notify the Wastewater Operations Manager.

Mobilization times during non-business hours vary, depending upon personnel travel times and time of day. During non -business hours, the City endeavors to achieve a goal of first response and spill site assessment within 30 minutes. The City further endea vors to achieve a goal of having a response team at the site within one hour of receipt of the spill report. If initial assessment indicates the need for more crews than are on call, Wastewater Division supervisors are empowered to authorize overtime and mobilize any required off-duty personnel to respond to the spill.

EQUIPMENT AND PERSONNEL

Utilities Department resources from both the Wastewater and Public Works Divisions are available to respond to spills. This chapter summarizes resources available to the City of Escondido in responding to spills or threatened spills.

3.1 Personnel and Organization
Response Personnel. Available Utilities Department response personnel include both personnel from the Wastewater Division and Public Works Division. First response teams will be from the Wastewater Division (see Attachment 2 for the Wastewater Division organization chart), and additional City personnel will be called in as required. Personnel available to respond to spills or threatened spills include:
• Wastewater Division and Public Works Division management and field personnel. • Sewer collection system specialists.
• Storm drain specialists.
• Mechanical and electrical specialists.
• Environmental and monitoring specialists.
• Additional response team personnel available for use in wastewater containment, cleanup, facilities repair, spill mitigation, site and traffic control, and spill notification and documentation duties.

City of Escondido Utilities Department personnel are knowledgeable of wastewater collection facilities and operations and receive ongoing training. A number of the Wastewater Division management personnel and staff are cross-trained in multiple disciplines.

Designation of Onsite Supervisor. All spill response actions detailed in Chapter 4 of this Spill Emergency Response Plan will be directed by an Onsite Supervisor. For all spills within the City's wastewater system, designated Onsite Supervisor will be the Wastewater Collections Supervisor or his/her designee.

When Utilities Department staff arrive at the spill scene in advance of the designated Onsite Supervisor, the senior onsite Wastewater Division staff member will assume the duties of the Onsite Supervisor until the designated Onsite Supervisor arrives.

Resolution No. 2025-103
Exhibit "A"

Page 80 of 102 ends

113
Item7.

Any received spill reports shall be immediately directed to the designated on -call Onsite Supervisor as well as the Wastewater Collections Supervisor, Wastewater Operations Manager and Assistant Director of Utilities/Wastewater.

Response Teams. All Utilities Department workers are available via cell phone/radio communications during business hours. As discussed in Section 2.3 (pages 2 -5 through 2-7), Utilities Department supervisors can quickly mobilize spill response crews by (1) routing crews already in the field to the response site and/or (2) directing crews at Utilities Department offices/yards to the response site.

The Wastewater Collections Supervisor is to ensure that schedules are maintained so that a senior -level supervisor and spill response crew is scheduled as being on call and available during all non-business hours.

3.2 Training
Utilities Department personnel spill response training is the responsibility of the Director of Utilities, the Assistant Director of Utilities/Wastewater, the Wastewater Operations Manager, and the Wastewater Collections Supervisor. Ongoing Utilities Department training includes:
• Orientation Training and Mentorship. New employees are trained in assigned duties by experienced Utilities Department staff. Supervisors serve as mentors in order to allow newer employees to better understand City wastewater facilities, staff responsibilities, and wastewater system operations.
• Specialized Training. Using either Utilities Department staff or outside instructors, Utilities Department personnel receive periodic training in such areas as first aid, safety (including confined space entry and ventilation), fire prevention, traffic control, and equipment operation. • Coordination with Storm Drain Staff. Since storm drains with the City of Escondido are maintained by City, City storm drain and wastewater staff routinely coordinate and cooperate in preparing for and responding to spill events.
• Drills and Test Exercises. Utilities Department drills and training exercises are periodically conducted by senior Utilities Department staff. Drills and test exercises directed by senior Utilities Department staff include notification tests, equipment tests, communication tests, mobility drills, and trouble-shooting training.
• Professional Training and Certification . Utilities Department employees are encouraged to achieve professional certifications and participate in such professional organizations as Water Environment Federation and California Water Environment Association. Employees are encouraged to attend training sessions and semi nars that relate to sewer system operation, spill prevention, spill containment, and spill recovery. Additionally, Wastewater Division staff are regularly enrolled in California Water Environment Association spill prevention and response seminars.
• Professional Development. Professional promotions within the Utilities Department are, in part, based on employee's work performance, professional certifications, and well-rounded knowledge of all facets of the City's wastewater facilities and operations. Employees seeking advancement are thus encouraged to (1) cross -train in areas beyond their normal duties and (2) increase their breadth of knowledge outside their immediate responsibilities.

SPILL RESPONSE ACTIONS

4.1 S pill Response Overview
This chapter summarizes City of Escondido Utilities Department actions for responding to sewer system spills. All spill response actions will be under the direction of the designated Onsite Supervisor.

Response actions shall include:
• Initial assessment and spill classification.
• Office of Emergency Services (OES) and RWQCB notification.6 • Securing the site perimeter.
• Spill containment.
• Posting.
• Spill control.
• Monitoring and spill documentation.
• Site cleanup and restoration.
• Follow-up activities.

Response actions taken by the City will be in accordance with provisions established within SWRCB Order No. WQ 2022-0103-DWQ.

4.2 Initial Assessment and Spill Classification
Initial Assessment. When arriving onsite, the Onsite Supervisor shall assume direction and management of all response personnel and resources. The Onsite Supervisor shall take command of onsite Utilities Department staff, assess the spill site, and collect information from Utilities Department staff to:
• Identify what is causing the spill (or threatening to cause the spill). • Determine where the spilled sewage will flow and identify potentially affected areas. • Identify strategies for gaining site control and keeping people and spectators away. • Assess strategies for containing the spill, and identify personnel and resources required for spill containment.
6 OES notification is required for spills from public sewer systems that exceed 1000 gallons and will (or are projected to) discharge to surface waters. OES notification is voluntary if the spill exceeds 1000 gallons and originates from a privately -owned sewer lateral or collection system. RWQCB notification (per RWQCB Order No. R9-2007-0005) is required for any spill of 1000 gallons or more. Notification to the RWQCB is to occur within 24 hours of becoming aware of the spill.

Resolution No. 2025-103
Exhibit "A"

117
Item7.
• Assess strategies for terminating or redirecting the source of the spill, and identify personnel and equipment required to terminate the spill source.
• Determine if the spill has the potential to threaten public health, cause property damage, or impact the environment.
• Communicate the nature of the problem to the Assistant Director of Utilities/Wastewater and the Wastewater Operations Manager. Depending on the nature of the spill, the Assistant Director of Utilities/Wastewater may consult the Director of Utilities. • In consultation with the Assistant Director of Utilities /Wastewater and Wastewater Operations Manager, call in required additional personnel and equipment resources. • If the spill discharges to surface waters (Category 1 Spill) or exceeds 1000 gallons in volume (Category 2 Spill), call OES at (800) 852-7550 within two hours of becoming aware of the spill, provide the OES with requested information, and obtain a notification control number from the OES. Also notify the RWQCB within 24 hours of becoming aware of any spill to surface waters that exceeds 1000 gallons in volume.
• Consult with other primary responders contacted by OES (e.g., health officials or other responding agencies) and determine if any downstream parties need to be notified to protect public health. • Estimate the duration and volume of spilled sewage.
• Determine if any upstream dischargers need to be contacted to reduce wastewater quantities discharged to the sewer system.

Spill Classification. Table 4-1 (page 4 -3) presents SRWQCB classifications for spills , as defined within SWRCB Order No. WQ 2022-0103-DWQ.

Per Order No. WQ 2022-0103-DWQ, Category 1 spills are defined as a discharge of untreated or treated wastewater of any volume that reach surface water or a drainage channel tributary to surface water.

Category 1 spills also include any discharge untreated or partially treated wastewater that reaches a Municipal Separate Storm Sewer System (MS4) and is not fully captured and properly disposed (unless the MS4 is tributary to a dedicated groundwater infiltration or percolation basin).

4.3 Notifications
Office of Emergency Services (OES) Notification. In accordance with the requirements of Order No.

Following the initial notification to OES, the Utilities Department shall provide updates to OES on any substantial changes in the estimated volume of untreated or partially treated wastewater or any substantial changes to known impacts. This notification shall be made by the Onsite Supervisor if such substantial changes are in evidence while City crews are still on the scene responding to the spill . The Collections System Supervisor shall make the report to OES if such substantial changes are determined to have occurred after City response crews have left the site but prior to the time the spill report is logged into the CIWQS (California Integrated Water Quality System) sanitary sewer system database.

Order No. WQ 2022-0103-DWQ encourages (but does not require) sewer system operators to notify OES of discharges to surface waters exceeding 1000 gallons from private lateral sewer discharges (PLSDs). 7 In accordance with this directive, the City shall endeavor to notify OES whenever City staff become aware of PLSDs to surface waters that exceed 1000 gallons.

RWQCB Notification. RWQCB Order No. R9 -2007-005 establishes spill reporting requirements in addition to state-wide spill reporting requirements established in SWRCB Order No. WQ 2002-0103-DWQ.

RWQCB Order No. R9-2007-0005 requires agencies to notify the RWQCB via telephone or email within 24 hours
8 of becoming aware of a spill of 1000 gallons or more from a public sewer system or private lateral that reaches surface waters. The RWQCB notification is to include:
• The name of the sewer agency.
• The name and telephone number of the agency person reporting the spill. • The estimated spill volume.
• The location of the spill and the affected receiving water. • The start time of the spill and (if applicable) the end time of the spill. • Confirmation that the local health agency has been notified.

4.4 Site Perimeter and Traffic Control
Site Perimeter Control. Concurrent with the initial assessment, the Onsite Supervisor shall take immediate actions to isolate the public from the spill. Site control shall be achieved using portable barriers, signs or postings, stakes and tape, existing fencing, parked vehicles, or natural terrain.

The Onsite Supervisor shall contact the City of Escondido Police Department if additional assistance is required for (1) isolating the public from the spill, (2) controlling crowds or onlookers, or (3) controlling members of the public are interfering with efforts of the spill response team.

Traffic Control. If the potential exists for spill response actions (or parked response vehicles) to impact traffic, the Onsite Supervisor shall also take actions to divert traffic around the response site and ensure the safety of traffic, the public, and response crews. Traffic shall be diverted where necessary using traffic cones, portable signs, emergency lights, flag personnel, vehicles, and/or portable traffic-direction light trailers.

7 Per Section 5.15 of Order No. WQ 2022-0103-DWQ, reporting of spills from privately-owned laterals or systems is voluntary. 8 Provided that such 24-hour notification can be provided without substantially impeding cleanup or other emergency measures.

Item7.

City response vehicles routinely carry traffic cones, barriers, and traffic control flags, and signs.

Additional materials required to secure the site perimeter (which include portable traffic-direction light trailers) are stored at City maintenance yards and will be secured by the Onsite Supervisor if required.

The Onsite Supervisor shall determine if onsite traffic control is adequate, or if law enforcement assistance is required. The City of Escondido Police Department should be notified if required to assist in traffic control. Fire Department officials should be contacted if traffic controls could result in fire response delays. Response vehicles and crews are required to maintain current telephone numbers for the Police Department and Fire Department.

4.5 Spill Containment or Diversion
Upon achieving control of the site perimeter, response crews under the direction of the Onsite Supervisor shall endeavor to contain or divert the spill. To determine the best strategy (or strategies) for spill containment or diversion, the Onsite Supervisor shall evaluate the:
• Spill volume and flowrate of the spill.
• Terrain and natural barriers.
• Locations of downstream manholes or other sewer collection sewer facilities. • Locations or storm drains or streams.

Spill and recovery containment strategies to be evaluated, and (if appropriate) implemented by the response crews include:
• Using combination trucks to vacuum the spill.
• Using sandbags rubber dams, or other portable flow barriers to prevent the flow from entering storm drains or drainage channels.
• Diverting the spill by pumping around the overflow point or sewer break point back into the sewer system.
• Diverting the spill by berms or sandbags back into the sewer system. • Diverting or retaining the spill in a hollow, swale, or low area for subsequent recovery. • Constructing a temporary dam or dike to contain the spill for subsequent recovery.

Recovery from Storm Drains. City response vehicles are equipped with maps of municipal storm drain facilities. If the spill enters a storm drain, the Onsite Supervisor shall make all reasonable efforts identify a downstream location(s) where the storm drain can be dammed up to prevent the spill from reaching surface waters. The Onsite S upervisor will also contact the Public Works Department storm drain supervisor to coordinate any response actions involving City storm drain facilities. Any spilled flow contained within the storm drain facilities shall be subsequently removed by portable pumps or combination trucks and discharged to the sanitary sewer system.

Resolution No. 2025-103
Exhibit "A"

Item7.

4.6 Posting
The City maintains an inventory (stored at HARRF) of signage for use in warning the public of contact with areas contaminated by spills. In consultation with San Diego County EHS and in accordance with EHS regulations, affected areas shall be identified and posted as being contaminated with sewage.

Signage shall be posted in locations so as to maximize public visibility and minimize the potential for public contact with contaminated areas. Signs shall be posted along all routes the public may be reasonably expected use to enter the contaminated area.

Signs shall remain posted for a minimum of five days, unless the Utilities Department is otherwise directed by San Diego County EHS.

4.7 Spill Termination
Once spill containment is assured, response crews shall focus on eliminating the source or cause of the spill and terminating the spillage.

Gravity Sewer Main Breaks. For spills caused by breaks or failures of gravity sewer mains, the Onsite Supervisor shall determine the location and nature of the sewer main break, and identify equipment and resources required to repair the break. After sewage diversion actions are implemented, excavation equipment shall be called in to expose the break and allow the Onsite Supervisor to determine the appropriate measures for repairing the break. Minor breaks may be resolved with sleeves, patches, or fittings, while major breaks may require replacement of pipe sections.

The Onsite Supervisor shall assess whether the spill or potential repair actions associated with the spill may affect nearby water or stormwater conveyance facilities. The Onsite Supervisor shall coordinate with applicable water or stormwater conveyance op erators in making this determination and assessing whether (and how many) water system or stormwater staff are required as part of the spill response effort.

Gravity Sewer Main Blockages . For spills caused by sewer main blockage, the Onsite Supervisor shall determine the location and nature of the sewer main blockage, and identify equipment and resources required to clear the blockage. Once the nature of the blockage is identified, blockages may be removed by a variety of strategies including:
• Sewer main water jetting.
• Application of degreasers.
• Combination truck pumping.
• Sewer main rodding.
• Manual removal.

Gravity Sewer Main Surcharging. For spills caused by gravity main surcharging, t he Onsite Supervisor shall determine the nature and cause of the temporary surcharging, and direct actions to (1) temporarily Resolution No. 2025-103
Exhibit "A"

122
Item7.
divert wastewater flows, and (2) eliminate the cause of the surcharging. Activities required to eliminate the surcharging may include:
• Restoring manhole covers removed by citizens or by force of flow. • Installing temporary dikes or dams to protect facilities from runoff or standing water.

If the sewer system surcharging is caused by inflows of stormwater from flooded streets due to improperly operating storm drains, it may be necessary to eliminate the street flooding by unblocking or cleaning the storm drains to allow storm runoff to flow into the storm drains instead of flowing into the sanitary sewer system.

Pressure Main Ruptures. For spills caused by breaks of failures in pressure mains, the Onsite Supervisor shall determine the location and nature of the break/failure, and identify equipment and resources required to (1) divert flows around the rupture and (2) repair the break. After sewage diversion actions are implemented, excavation equipment shall be called in to expose the rupture and allow the Onsite Supervisor to determine the appropriate measures for repairing the break. Minor ruptures may be resolved with sleeves, patches, or fittings, while major breaks may require replacement of pipe sections.

The Onsite Supervisor shall assess whether the spill, potential repair actions, or erosion effects associated with the pressure main spill may affect nearby water or stormwater conveyance facilities. The Onsite Supervisor shall coordinate with applicable w ater or stormwater conveyance operators in making this determination and assessing whether (and how many) water system or stormwater staff are required as part of the spill response effort.

Pump Station Pump/Motor/Control Failure . For spills caused by pump station failure, the Onsite Supervisor shall determine the nature of the pump, motor, or control failure, and identify equipment and resources necessary to restore pump station operations. For use in the pump or motor repairs, an inventory of spare pumps, pump parts, motor bearings, and electrical controls are available at the Utilities Department maintenance yards.

If automatic controls fail, Wastewater Division staff are to revert to manual operation of pumps until the automatic controls are repaired or restored. If required, the Utilities Department maintains portable pumps and diversion equipment for use until full pump station operations are resumed.

Pump Station Electrical Failure. For spills related to electrical failures, t he Onsite Supervisor shall determine the nature and cause of the failure of onsite emergency generators to actuate upon power grid failure, and take actions to restore pump station power. Power restoration response actions shall include:
• Restarting onsite emergency generators using manual controls. • Order mobile generators to the site.
• If onsite emergency generators cannot be manually started, hook up the mobile generators and restore power.
• Determine if onsite repair of the emergency generators or generator controls is possible. • Maintain mobile generators at the site (even after grid power is restored) until the source of problems for the onsite emergency generators is diagnosed and corrected.

Item7.

Pump Station Surcharging. For spills caused by pump station surcharging, t he Onsite Supervisor shall determine the nature and cause of the temporary surcharging, and direct actions to eliminate the cause of the surcharging. Activities required to eliminate the surcharging may include:
• Restoring manhole covers removed by citizens or by force of flow. • Installing temporary dikes or dams to protect facilities from runoff or standing water.

If the pump station surcharging is caused by inflows of stormwater into the sanitary sewer system from flooded streets due to improperly operating storm drains, it may be necessary to eliminate the street flooding by unblocking or cleaning the storm drains to allow storm runoff to flow into the storm drains instead of flowing into the sanitary sewer system.

4.8 Assessment, Cleanup and Restoration
Monitoring. For spills in excess of 50,000 gallons that reach surface water, SWRCB Order No.

WQ 2022-0103-DWQ requires daily receiving water monitoring during each day of the spill for ammonia, total coliform, fecal coliform, E. Coli and enterococcus. Daily receiving water quality monitoring is required at the following locations:
• DSC-001, the point in a drainage conveyance system before the drainage conveyance system discharges into a surface receiving water (representative of the spill quality itself). • RSW-001, the point in the receiving water where the spill initially enters the receiving water. • RSW-001U, a point in the receiving water upstream from the point where the spill enters surface waters (e.g., characterizing unimpacted upstream receiving water conditions). • RSW-001D, a point in the receiving water downstream from the point of discharge where the spill is fully mixed with the receiving water.

Daily sampling is to commence no later than 18 hours after the City’s knowledge of a potential discharge to surface water. Additionally, if warranted after consultation with San Diego County EHS and onsite Utilities Department environmental specialists, the Onsite Supervisor shall direct staff to collect bacteriological water quality samples at additional sites to assess possible impacts to public health and the environment. Samples shall be labeled to show the collection date, time, and site.

The Onsite Supervisor (in consultation with Wastewater Division management) is responsible for (1) developing and implementing protocols for water quality monitoring, (2) determining where monitoring may not be possible as a result of safety concerns or access restrictions, (3) ensuring that monitoring instruments and devices are properly maintained and calibrated, and (4) maintaining records that document instrument maintenance and calibration.

Collection of Photographic/Video Evidence. Where possible and appropriate during and after spill response activities, the Onsite Supervisor shall direct that photographic or video evidence be collected to document (1) City response actions, (2) spill causes, (3) impacts to public health or the environment, and (4) cleanup and restoration measures. Photographic or video evidence shall be label ed to show the date, location, time, and person recording the event.

Site Cleanup and Restoration. After spill control is achieved, City response crews shall endeavor to return all spilled sewage to the sewer system (or as much as possible) and return the spill site to pre-spill conditions. Site cleanup operations shall be directed by the Onsite Supervisor, in consultation with San Diego County EHS . If necessary, t he City maintains on -call contracts for safely removing and cleaning chemical and biologically hazardous material such as chemicals spills, or blood and tissue clean-up from accidents. Additionally, the City will contact the Fire Department if any chemical or biologically hazardous materials appear involved in the spill.

Where appropriate, combination trucks or portable pumps shall be used to recapture spilled sewage and return it to the sewer system. Affected pavements, hardscapes shall be flushed with water, with flush water being recaptured and returned to the sewer system. Affected areas are to be assessed for impact to public health, biological resources, and other beneficial uses. Spill containment measures (barriers, dike, or dams) are not to be removed until the entire site clean-up is complete.

As part of this cleanup effort, City staff will (if storm drains are involved) c oordinate with Public Works Department storm drain staff to ensure protection and integrity of storm water collection facilities.

Additionally, if potable water conveyance facilities are near the spill site, City wastewater staff will coordinate with Water Division system staff to ensure that repair or cleanup efforts do not endanger or adversely impact potable water conveyance facilities.

4.9 Reporting and Follow-Up Actions
Corrective Actions and Mitigation. After site cleanup, the Onsite Supervisor shall determine if any short-term corrective or mitigating measures are required to prevent spill recurrence. Short -term corrective measures may include:
• Temporarily stationing Utilities Department personnel at the site to monitor conditions and/or equipment after the spill is terminated.
• Stationing response equipment at the site until it can be confirmed that the spill threat is no longer present.
• Ordering additional immediate repair activities to strengthen the integrity of the wastewater collection system.
• Implementing special short-term video inspection of collection mains.

The Onsite Supervisor, in consultation with the Assistant Director of Utilities/Wastewater or the Director or Utilities, shall also recommend any required long-term corrective measures. Long -term measures may include:
• Increased frequency of video inspection of suspect pipe sections. • Replacing suspect pipe sections.
• Replacing or repairing suspect equipment.
