STAFF REPORT TO THE CITY COUNCIL
DATE: Regular Meeting of April 22, 2025
TO: Honorable Mayor and Members of the City Council
SUBMITTED BY: Andrew Little, Consulting Project Manager (lnterwest) APPROVED BY: Scott Buenting, Public Works Director/City Engineer� SUBJECT: Resolution to Summarily Vacate Surplus Portions of Water Line Easement and Authorize the City Manager to Execute Any Additional Documents to Quitclaim to the Underlying Fee Owner and to Authorize the City Manager to Accept Additional Water Line Easements for the Walmart Project at 4893 Lone Tree Way; P.W. 727
RECOMMENDED ACTION
It is recommended that the City Council adopt a resolution to summarily vacate surplus portions of a water main line easement and quitclaim any interest to the underlying fee owner and authorize the City Manager or designee to accept new easements for a relocated water main line.
FISCAL IMPACT
There is no cost to the City for the abandonment of portions of the existing water line easement and creation of new water line easements. The Developer will pay for staff costs to process the required documents and the relocation.
DISCUSSION
On August 11, 2015, Record Document No. 2015-0166615-00 was recorded at the Contra Costa County Recorder's Office, granting a water line easement to the City of Antioch from WAL-MART REAL ESTATE BUSINESS TRUST, a Delaware statutory trust over a portion of Parcel 1 of Parcel Map M.S. 302-98 Contra Costa County.
Since the recording of these documents, Walmart has requested re-alignment of an existing public water line, abandoning portions of an existing water line easement (Staff Report Attachment 'D', Record Document No. 2015-0166615-00) and granting to the City new water line easements for the re-aligned public waterline. p

Antioch City Council Report
April 22, 2025 Agenda Item #P 2
Under certain conditions, the City Council may summarily vacate excess street, highway right-of-way, or public service easement pursuant to California Streets and Highways Code sections 8333 and 8335 by adopting a resolution of vacation. Under California Streets and Highways Code section 8333, subdivision (c), those conditions include circumstances when the easement has been superseded by relocation or determined to be excess by the easement holder. Because the easement holder relocated the facilities to accommodate the addition of 7,250 square feet to the existing building, staff has determined the easement to be superseded by relocation and excess. The original facilities which were relocated are no longer active and abandoned.
A public hearing is not required for summary vacations pursuant to California Streets and Highway Code sections 8335 and 8336. The summary vacation shall be made pursuant to California Streets and Highways Code section 8335 and shall include the name or other description. The description of the portion to be vacated may be by a precise map. At this time, staff recommends that the Council summarily vacate the surplus portions of the existing easement and authorize the City Manager to execute any additional documents necessary to vacate and quitclaim any interest to the underlying fee owner and accept the dedication of a new easement for water line purposes. Upon recordation, the street, highway, or public service easement vacated shall no longer constitute a street, highway, or public service easement (California Streets & Highways Code sections 8335(b)(4) & 8336).
The Developer is currently in the process of adding 7,250 square feet of building to the existing Walmart located at the Northwest corner of Lone Tree Way and Hillcrest Avenue under City of Antioch building permit B2023-2477. The addition is proposed over the existing easement and requires the line to be relocated to accommodate the building expansion.
To minimize utility conflicts and provide easier future maintenance of all utilities the new water line and easement have been relocated to the east side of the building.
No options are provided as the alignment of the original easement is needed to construct the project.

2025 SSMP Update
April 2025
1 1 Sewer System Management Plan Goal and Introduction
This section of the SSMP outlines the City’s goals for managing, operating, and maintaining its sanitary sewer system.
1.1 Regulatory Context
This Sewer System Management Plan (2025 SSMP) is an update to the City of Antioch (City) Sewer System Management Plan prepared on October 2018 (2018 SSMP) [1]. The 2018 SSMP was prepared to satisfy the requirements of the State Water Resources Control Board (SWRCB) Order No. 2006 -0003-DWQ, Statewide General Waste Discharge Requirements (WDRs) for Sanitary Sewer Systems [2].
In December 2022, the SWRCB adopted Order WQ 2022 -0103-DWQ, Statewide Waste Discharge Requirements General Order for Sanitary Sewer Systems (General Order), which updated, expanded, and clarified sections of the WDRs [3]. This General Order serves as a statewide waste discharge requirement and supersedes the previous SWRCB Order 2006-0003-DWQ and its subsequent amendments.
The 2025 SSMP was developed to comply with the requirements outlined in the current SWRCB General Order.
1.1.1 Purpose
The purpose of an SSMP is to document ongoing local sewer system management program activities, procedures, and decision-making. The 2025 SSMP addresses short-term and long-term system resilience through:
1. Proactive planning and decision-making;
2. Updated operations and maintenance activities and procedures;
3. Identification of high-risk system spill areas;
4. Implementation of capital improvements; and
5. Sufficient local budget to support staff resources, contractors, equipment, and training.
The 2025 SSMP presents a plan to reduce the overall volume of sanitary sewer overflows (SSOs) and prevent future occurrences of SSOs. The City shall develop and implement an updated SSMP to facilitate adequate local funding and management of its sanitary sewer system.
1.1.2 Background
The requirements for the SSMP are closely related to the Environmental Protection Agency (EPA) Capacity, Management, Operation, and Maintenance (CMOM) program and constitute the Best Management Practice (BMP) approach to regulating collection systems.
The 2025 SSMP requirements, as established in the General Order are as follows:
1. Sewer System Management Plan Goals and Introduction
2. Organization
3. Legal Authority
City of Antioch
2025 SSMP Update
April 2025
2 4. Operation and Maintenance Program
5. Design and Performance Provisions
6. Spill Emergency Response Plan
7. Sewer Pipe Blockage Control Program
8. System Evaluation and Capacity Assurance Plan and Capital Improvements
9. Monitoring, Measurement and Program Modifications
10. Internal Audits
11. Communication Program
Each of these elements is addressed in the following sections, including a description of the SWRCB requirement and any supporting information for that element. The WDRs have established an SSMP implementation schedule based on the size of the agency.
The SWRCB has established an SSO database that is part of the Central Integrated Water Quality System (CIWQS), a secure, online regulatory and water quality information management system. The SSO online database provides the City secure access for electronic reporting.
1.1.3 Goals
The City’s goals are:
1. To properly and safely manage, operate, and maintain all portions of the City’s wastewater collection system;
2. To provide adequate capacity to convey the peak wastewater flows to the City’s wastewater treatment plant. Adequate capacity, for the purposes of the SSMP, is defined as the capacity to convey the peak wastewater flows that are associated with peak wet weather flows;
3. To minimize the frequency of SSOs;
4. To mitigate the impacts that are associated with any SSO that may occur; and
5. To meet all applicable regulatory notification and reporting requirements.
1.2 SSMP Update Schedule
Under the General Order, the City shall update its SSMP every six (6) years after the date of its last SSMP Update due date. The City shall conduct an internal program audit at a minimum frequency of once every three (3) years. The audits are due within six (6) months after the end of the 3 -year audit period. The SWRCB has created a website for searching required due dates using the Waste Discharge Identification (WDID) number : https://www.waterboards.ca.gov/water_issues/programs/sso/lookup/. The SWRCB’s WDID number for the City’s collection system is 5SSO10890. Table 1-1 summarizes the following due dates for the SSMP update and audit.

15 2.4 Chain of Communication for Reporting SSOs
The City’s SSO response begins with identifying whether the issue originates from a City-owned main or a private lateral. For private spills, field staff document the incident with photos, notify the property owner, provide educational materials, and recommend hiring a plumber. If the owner is unavailable, staff leave a door hanger and voicemail. Unresolved or escalated cases may involve supervisor review and coordination with health or enforcement agencies. If directed, City crews may clear private blockages and record time and equipment for cost recovery.
For City system spills, responders log arrival time, assess severity, and mobilize additional resources if needed. Spills over 1,000 gallons or threatening surface waters require immediate notification to Cal-OES.
Staff initiate containment, document the site extensively, and prioritize protection of sensitive areas such as storm drains, schools, and intersections. Containment may involve vacuum trucks, mats, pumps, and barriers.
Crews address the blockage, clean the area, and collect debris, with follow -up sampling and shoreline cleanup required if surface waters are impacted. When spills reach drainage systems, responders seal the system, recover sewage, and flush with three times the spill volume.
If private property is affected, staff complete a First Responder Form, provide claim information and lodging if needed, and document cleanup consent or refusal. Restoration teams may assist, and disinfecting efforts are carefully managed to avoid stormwat er contamination. Final steps include completing the City’s official Spill Report, compiling documentation, and notifying the City Attorney’s Office and relevant regulatory agencies.
For additional information regarding the City’s chain of communication , refer to the Spill Emergency Response Plan located in Attachment F, Section C, page 1-4. A visual representation of the communication structure for reporting spills is also provided in Figure 2-2.

the 2-hour notification to Cal-OES and obtain a
control number. Record this number on the
following pages: A-4, B-2, and D-1 Page 1.
1. Record manhole number or cleanout location of the spill appearance point closest to the failure point, and describe each additional appearance point on the Spill Report (D-1).
2. Take photographs of all spill appearance points, the extent of the spill, and spill boundaries.
Go to NEXT PAGE
This is a Private Spill
1. Photograph the extent of the discharge and the discharge boundaries if possible.
2. Notify the property owner that the blockage is in their lateral and that the City does not have legal authority to maintain or perform work on privately-owned laterals.
3. Give customer the “Your Responsibilities as a Private Property Owner” pages from this Workbook (F-6).
4. Recommend to customer they hire a contractor to clear their line.
5. If customer is not home:
- Complete Door Hanger and leave on customer’s door.

BEGIN DIVERSION AND CONTAINMENT, AS NECESSARY
1. DIVERT AWAY FROM SENSITIVE AREAS:
a. Cover unplugged storm drains w/mats, or use dirt/other material to divert sewage away from sensitive areas (e.g., schools, playgrounds, intersections, etc.)
b. ENSURE PUBLIC CONTACT DOES NOT OCCUR. Use cones/barricades to isolate area.
2. CONTAIN SPILL & RETURN TO SYSTEM, IF POSSIBLE:
a. As practical, plug or block drainage conveyance system entry locations or use rubber mats to cover basin inlet and divert flow to a downstream sanitary sewer manhole (barricade manhole if left open and monitor after barricade) or area suitable to capture the spill for later collection.
If any amount has already reached the drainage conveyance system, trace it downstream to a dry manhole and block it from entering surface waters. i.e., plugs, sandbags, or vacuum truck. b. If you are confident that you can capture the spill in the drainage conveyance system, trace it downstream to a dry manhole and then divert the spill to the drainage conveyance system for later recovery and return to the sanitary sewer.
c. Use bypass pumps to pump around blockage until it can be removed. d. Divert to low area of ground where it can be collected later.
3. PHOTOGRAPH each drainage conveyance system entry location.
ADDRESS CAUSE OF SPILL/BACKUP ASAP
1. For spill/backups not related to a pump station, relieve the stoppage. Note the distance of the obstruction from the manhole and catch/remove debris that could cause another stoppage. After flow has returned to normal, clean the pipe thoroughly. Consider televising (CCTV) the affected line.
2. For pump station related spill/backups refer to that station’s Emergency Response Plan.
3. Photograph staff activities while clearing the blockage.

1. Sample surface waters the spill has reached if safe and if the property owner allows (if the surface water access point is on private property):
• If preliminary volume estimates of the spill are 50,000 gallons or greater, begin collecting as soon as possible but no later than 18 hours after becoming aware of the spill.
• If people are fishing or swimming in the waters, collect samples regardless of the volume of the spill.
2. Refer to and follow the sampling standard operating procedure (Tab G in this Workbook).pictures.

IMPACTED AREA CLEANUP, AS NECESSARY
1. Assign staff to begin cleanup. If you might use the area measured volume method to estimate the volume, draw a sketch of the spill footprint and capture dimensions before washing it down.
2. Remove all signs of gross pollution with a shovel, broom, rake, and bucket. (toilet paper, solids, grease, etc.)
3. Flush impacted area with 3X amount of spill, if possible, and contain. Record volume of flush water used and volume of flush water returned to the sanitary sewer on the Spill Report (D -1).
4. Setup berm/other means to contain all water so it can be returned to sewer.
5. Don’t use disinfectants if they may enter storm drain system and not be fully recovered or if they may enter surface waters.
6. Address saturated soil with removal and/or in -place treatment, depending on the extent of the contamination, the location, and land use. Take measures to prevent accidental contact by the public.
NOTE: addressing saturated soil may involve returning to the site one or more days after the spill event.
7. Photograph the area when cleanup operations are complete Go to NEXT PAGE
DRAINAGE CONVEYANCE SYSTEM CLEANING SOP

22 4 Operations and Maintenance Program
This section of the SSMP provides an overview of the City’s sewer system operations and maintenance program. It is also intended to provide a checklist to support future SSMP audits.
Regulatory Requirements
To meet the requirements in the General Order, the 2025 SSMP must:
1. Maintain an up-to-date map of the sanitary sewer system, showing all gravity line segments and manholes, pumping facilities, pressure pipes and valves, and applicable stormwater conveyance facilities within the sewer system service area boundaries;
2. Provide a scheduling system and data collection system for preventative operation and maintenance activities conducted by staff and contractors;
3. Provide in-house and external training on a regular basis for sanitary sewer system operations and maintenance staff for contractors; and
4. Provide an inventory of sewer system equipment, including identification of critical replacement and spare parts.
4.1 Updated Map of Sanitary Sewer System
The City uses GIS, which includes information on its wastewater collection system assets, including gravity line segments, manholes, pumping facilities, and force mains. The City also has information on its GIS for its storm drainage system. The GIS information is available to appropriate City staff. An up-to-date map of the sanitary sewer system showing the sewer facilities within the service area boundary is shown in Figure 1-1.
Field crews have access to electronic GIS maps that are accessed via tough book computers and/or tablets.
These maps are accessed on the City’s web portal or by logging onto their CMMS. If access to the City’s web portal or CMMS is unavailable, the crew can revert back to hard copies stored in their vehicles. These GIS maps are updated annually. Corrections that are identified by the field crews are noted on their portable device and submitted to the main office for review . Corrections and new facilities ar e incorporated into the maps during the annual update.
A copy of the GIS map of the City’s wastewater collection system can be obtained from the City’s website and via following the link : https://www.antiochca.gov/public-works-department/geographic-info- systems/geographic-info-systems-gis-gallery/.
4.2 Preventive Operation and Maintenance Activities
The elements of the City’s sewer system Operation and Maintenance (O&M) Program include:
1. Proactive, preventive, and corrective maintenance of gravity sewers , upper laterals, and lower laterals;
2. Ongoing CCTV inspection program to determine the condition of the gravity sewers;
3. Rehabilitation and replacement of sewers that are in poor condition; and
4. Periodic inspection and preventive maintenance for the lift stations and force mains.
City of Antioch
2025 SSMP Update
April 2025
23 The collection system organization chart for implementing the City’s O&M program is shown in Figure 2-
1. The details of the program are explained in the following sections.
4.2.1 Gravity Sewers
The City is responsible for the operation and maintenance of its wastewater collection system, including the upper and lower laterals that connect private upper laterals from residences and buildings.
Maintenance activities include CCTV inspections, root cutting, and lateral replacement during mainline sewer projects to ensure proper system function. To support these efforts, a dedicated CCTV inspection crew proactively inspects wastewater collection sy stem facilities, investigates stoppages and SSOs, and conducts condition assessments for the Capital Improvement Program (CIP). Over the past ten years, all gravity sewer main lines 10 inches in diameter or smaller have undergone inspections and CCTV assessments.
To ensure system reliability, the City conducts visual inspections of its wastewater collection system facilities during significant storm events. These inspections focus on sewers with known hydraulic limitations, pump stations, siphons, and creek crossings to identify potential vulnerabiliti es and mitigate risks. Additionally, the wastewater collection system staff maintains a prioritized list of known structural deficiencies, organized based on the Pipeline Assessment and Certification Program (PACP) Quick Rating System. High-priority structural deficiencies are repaired as soon as possible, either by the City’s sewer repair crew or an external contractor on an as-needed basis.
The City implements a proactive sewer cleaning program, ensuring that all sewer pipelines smaller than 24 inches are cleaned at least once every three years. Additionally, preventive cleaning is conducted for pipelines with a history of recurring issues (h ot spots) on a quarterly schedule. Approximately 73,625 linear feet, 4% of the sewer system, is currently included in the hot spot cleaning program.
All cleaning operations follow the evaluation criteria outlined in Attachment A, Criteria for Rating Cleaning Results, to assess and document the materials removed during the cleaning process. Large -diameter pipelines, 24-inches and larger, are cleaned by City crews or external contractors as needed. The City's cleaning operations are designed to restore any pipeline to at least 90% of its original capacity. A pipe segment remains in the hot spot program until it achieves three consecutive cleaning results classified as clear or light. This process ensures that problem areas are continuously monitored and maintained to prevent blockages and system failures.
The City also conducts more frequent cleaning for line segments that have been determined to require a higher frequency of cleaning. All high-frequency lines are cleaned on a quarterly basis. Table 4-1 provides detailed information on hot spot pipe cleaning for all pipes included in the program as of December 2014, while Table 4-2 summarizes high-frequency line statistics.

To further enhance system maintenance, the City conducts inspections and condition assessments of all manholes in the wastewater collection system at least once every three years. These assessments follow the Manhole Assessment and Certification Program (M ACP) condition rating criteria established by National Association of Sewer Service Companies (NASSCO). The results are used to identify necessary improvements and to develop prioritized capital renewal and replacement projects within the five -year capital improvement program.
The City has committed to inspecting and grading approximately 25 miles of gravity sewer main lines located within 200 feet of water bodies, which include streams, creeks, rivers, ponds, impoundments, lagoons, wetlands, or bays (excluding storm drainage channels). The City is also inspecting gravity sewer main lines exceeding 10 inches in diameter (excluding force mains) and grading all 25 miles of sewer mains using the PACP rating scale by NASSCO. The City is in the process of establishing return frequenci es for CCTV assessments before the next SSMP audit, utilizing the Decision Matrix for CCTV Return Frequency based on the PACP Rating System, which is included in Attachment B.
To address issues identified during CCTV inspections or sewer cleaning operations, the City maintains a sewer repair crew responsible for resolving minor defects in priority order. Significantly defective gravity sewer main lines, those rated 4 or 5 on the PACP scale, located within 200 feet of water bodies or in critical habitat areas for endangered species, receive the highest priority for repair and replacement. Major repairs that exceed the City's in-house capabilities are contracted to private contractors for completion.
As part of its ongoing televising and grading activities, the City follows a structured timeline for repairing and replacing identified defects. Gravity sewer main lines rated as Grade 5 on the PACP scale will be City of Antioch
2025 SSMP Update
April 2025
25 repaired or replaced within two years of their determination, while lines rated as Grade 4 will be addressed within four years. For Grade 3 sewer main lines, the City will assess the necessity of repairs and prioritize them accordingly, following a similar ranking system.
The City has recently completed CCTV inspection of all gravity sewer main lines , excluding force mains.
Following the completion of this effort, the City has reinitiated the CCTV inspection cycle for all gravity sewer main lines, with exceptions made for sewer mains that have either undergone CCTV inspection within the past ten years or have been constructed, replaced, or repaired within the past twenty years .
This ongoing program supports proactive asset management and helps ensure the continued integrity and performance of the sewer collection system.
To efficiently manage operations, the City utilizes CMMS to track complaints, plan and initiate work, generate work orders, and document completed work. The system provides electronic work orders for crews and responding personnel, which are later reviewed for accuracy and closed in the CMMS system for future management reporting.
Additionally, the City maintains standard operating procedures (SOPs) for collection system equipment.
These SOPs ensure consistency and efficiency in operating, maintaining, and repairing wastewater collection system infrastructure.
4.2.2 Pump Stations & Force Mains
The City implements a regularly scheduled inspection and maintenance program for the pump stations it operates and oversees. In addition to routine maintenance, the City conducts an annual comprehensive condition assessment of the entire pump station facil ity and force main system utilizing the Lift Station Condition Assessment Checklist.
A copy of the Marina Pump Station Inspection/Maintenance Checklist Form and the Lift Station Condition Assessment Checklist are provided in Attachment C.
The City also performs regular inspections of the force main alignment to identify any potential force main failures and assesses the discharge manhole for signs of corrosion where the flow exits the force main.
Refer to Table 4-3 for a summary of operative pump stations and refer to Table 4-4 for a summary of existing force mains.

26 4.2.3 Non-Routine Maintenance
Non-routine maintenance activities involve investigating and addressing complaints related to various sewer system issues. These include manhole overflows, missing or shifted manhole covers, excessively noisy manhole covers, residential plumbing problems, pump station malfunctions, unexpected sewer odors, and similar concerns. Complaints received by the Public Works Department are promptly investigated, and appropriate measures are taken to identify and resolve the underlying problems, ensuring the continued functionality and safety of the sewer sys tem. All complaints are logged into the CMMS system, including the final disposition of the complaint, as required by the WDR.
4.2.4 Private Sewer Laterals
On December 16, 2014, City staff presented an ordinance to the City Council that aimed to clearly define lateral responsibilities and potentially establish a mandatory inspection and/or repair program for privately-owned sewer laterals. At that time, the C ity Council tabled the matter, indicating that any reconsideration would require an affirmative vote by the City Council to bring it back for further discussion and potential action.
4.2.5 Root Foaming
The City contracts annually for root foaming treatment on specific pipeline segments known to experience root intrusion issues. This process typically involves an initial cutting of the roots, followed by the application of root foam two to three months la ter as new root growth begins to emerge. This method has proven to be a beneficial component of the City's overall maintenance program and will continue to be utilized as long as it remains an effective strategy for managing root intrusion within the colle ction system.
4.2.6 Rehabilitation and Replacement Program
The City maintains an ongoing sewer rehabilitation and replacement program to address deficiencies within the wastewater collection system as conditions warrant. Projects included in the City’s 5-Year CIP are detailed in Attachment D. The selection of projects for inclusion in the CIP is based on prioritization from CCTV condition assessments and input from field crews who identify problem areas through cleaning operations.
The Antioch 5-Year Capital Improvement Program 2024 -2029 outlines the City’s approach to sewer pipeline renewal and replacement. According to the report, there is a current backlog of approximately $6.5 million in sewer pipelines, existing infrastructure, and trash capture devices.

7.5.2 Enforcement Actions
Delta Diablo and the City will collaborate to identify FSEs contributing to FOG-related blockages or SSOs.
In such cases, Delta Diablo will conduct facility inspections to determine the source of the FOGs. If an FSE is found to be in violation of the requi rements of the Sewer Pipe Blockage Control Program —including failure to maintain an interceptor or trap as required under Delta Code §2.28.660—the City has the authority to initiate enforcement actions in accordance with Delta Code §2.28.665.
Enforcement actions may include:
• Verbal warnings;
• Written warnings;
• Administrative orders (which may include fines); and
• Disconnection from the public sewer system.
These enforcement measures are supported by the City's authority to require proper maintenance, prohibit decanting or illegal discharge of waste, and mandate documentation of compliance. Failure to comply—such as not maintaining equipment, failing to implement best management practices, or failing to follow lawful directives from the City or Delta Diablo—may result in escalating enforcement, as allowed by ordinance. These measures are designed to ensure FSE compliance, prevent blockages, and protect public health and the environment.
7.6 Identification of System Sections Subject to Blockages The City’s 2018-2023 SSMP Audit identifies SSOs attributed to FOG blockages occurring between January 2018 and June 2023 . In accordance with regulatory requirements, the City also uploads data on all reported SSOs to the SWRCB CIWQS website, including SSOs occurring as recently as 2024, to ensure accurate and up-to-date data management. The locations of blockage-related SSOs from 2021 to 2024 are shown in Figure 7-1. A copy of the City’s 2018-2023 SSMP Audit is provided in Attachment I.

36 7.7 FOG Preventative Maintenance
The City’s preventive maintenance programs currently prioritize problematic sewer line segments. The ongoing identification of FSEs and FOG hot spots will serve as the foundation for the Sewer Pipe Blockage Control Program, ensuring that FOG sources contributing to blockages or SSOs are included in the program. The results of sewer cleaning operations will be used to adjust and optimize sewer cleaning frequencies.
City staff will provide D elta Diablo’s Sewer Pipe Blockage Control Program Inspectors with timely notifications whenever gravity sewers experience FOG-related blockages or SSOs.
To enhance program effectiveness, Delta Diablo and the City will collaborate to update FOG hot spot areas on an annual basis. Preventive maintenance for gravity sewers within identified FOG hot spot areas will be performed at a frequency sufficient to minimize recurring FOG-related blockages and SSOs.

38 8 System Evaluation, Capacity Assurance and Capital Improvements
The System Evaluation and Capacity Assurance Plan section of an SSMP ensures the sewer system has adequate capacity to handle current and future flows. It includes assessing system performance, identifying capacity deficiencies, and planning for necessary upgrades or expansions to prevent overflows and maintain reliability.
Regulatory Requirements
The 2025 SSMP must include a system evaluation that includes:
1. Routine evaluation and assessment of system conditions;
2. Capacity assessment and design criteria;
3. Prioritization of corrective actions; and
4. A capital improvement plan.
8.1 System Evaluation and Condition Assessment
In February 2014, the Wastewater Collection System Master Plan (Master Plan) was updated to incorporate revised peak wet weather design flows based on modified base wastewater flow projections.
This Master Plan provided a comprehensive analysis of the City's wastewater collection system, supporting its ongoing efforts to upgrade se wer infrastructure. The planning effort included a detailed assessment of the trunk sewer system, utilizing flow monitoring data, rainfall records, and a hydraulic model to evalua te both existing conditions and projected expansion of the City’s service area over the next twenty years in accordance with the General Plan.
Additionally, the Master Plan assessed renewal and replacement needs for the City’s sewer system, based on an analysis of pipe age and material types, as outlined in Section 4 of this SSMP.
The City is in the process of updating the Master Plan to evaluate the sewer collection system and identify capacity improvements needed to support existing and future development through buildout.
8.2 Capacity Assessment and Design Criteria
The capacity-related design criteria, including base wastewater flow and peaking factors, are detailed in Section 5 of this SSMP and the City’s Master Plan [5]. These criteria establish the foundational parameters for evaluating and ensuring the capacity and performance of the wastewater collection system.
8.3 Prioritization of Corrective Action
The City is currently updating its Master Plan to incorporate findings from the condition and capacity assessments, which will inform the prioritization of corrective actions.
8.4 Capital Improvement Plan
The City's CIP for sewer main capacity enhancements is provided in Attachment D. This program outlines planned projects designed to address capacity needs within the wastewater collection system and provides a structured schedule with completion dates for recommended wastewater improvement projects.

39 The City of Antioch’s 2024 –2029 CIP includes five key wastewater and storm drain projects. The Sewer Facility Rehabilitation Program and Sewer Main Improvements Program (Projects 7736 and 7724) are ongoing, citywide efforts aimed at rehabilitating aging se wer lines and upgrading system capacity based on the Master Plan, each funded at $600,000 over five years. The Sewer Main Trenchless Rehabilitation project (Project 7923) uses cost-effective trenchless methods like pipe bursting and cured-in-place lining to replace deteriorated pipelines while minimizing surface disruption, with a total allocation of $950,000.
The Northeast Antioch Annexation Infrastructure project ( Project 7745), funded at $3.5 million, will construct new underground water and sewer infrastructure along key streets in the annexation area and may also include storm drainage, curb, gutter, and lighting improvements. Lastly, the Trash Capture Devices project ( Project 7750), with $900,000 in NPDES funding, will install full trash capture device s citywide to prevent debris from entering the storm drain system, ensuring compliance with MS4 stormwater permit regulations.
To complete these projects, the City will utilize both internal and external funding sources. In addition to revenue generated from ratepayers, the City will pursue grant opportunities and low-interest loan options available through programs such as the Regional Early Action Planning (REAP) Grants and the Clean Water State Revolving Fund (CWSRF) to support infrastructure improvements.

SECTION III: PROJECT DETAILS
City of Antioch | Capital Improvement Program Overview I-2
Capital Improvement Program Overview
Program Objective
The primary objectives of the City of Antioch’s Capital Improvement Program (CIP) are:
To provide professional and technical engineering services and support to all City Departments related to facility expansions and improvements, infrastructure rehabilitation and development.
To provide leadership in implementing Federal, State and Local programs.
The CIP relates the City’s annual capital expenditures to a long-range plan for public improvements. California Government Code Section 66002 requires local agencies that have developed a fee program to provide the approximate location, size and timing of projects, in addition to an estimate for the cost of all facilities or improvements to be financed by fees. This is frequently done by the adoption of a CIP and is the process Antioch uses to meet this requirement.
The Capital Improvement Budget document is different from the Operating Budget document, but the two budgets are closely linked. The Capital Improvement Budget, as distinguished from the Operating Budget, is used as a planning tool by the City to identify specific Capital Improvement needs consistent with the financing and timing of those needs in a way that assures the most responsible and efficient use of resources.
Projects within the CIP are allocated over five years using both existing and projected revenue sources. The Capital Improvement staff:
In consultation with other departments, determines upcoming capital needs. Prepares construction documents, including plans, specifications, bid documents and estimates for the needed projects or prepares procurement documents, as needed. Provides project management and construction oversight.
The CIP is a five-year plan to guide the construction or acquisition of capital improvements and includes the capital budget for the upcoming fiscal year, which is authorization from the City Council to expend dedicated revenues for specified projects. Prior to adoption by the City Council each year, the CIP is reviewed by the City’s Planning Commission to assure its consistency with the City’s current General Plan.
City of Antioch | Capital Improvement Program Overview I-3
The five-year CIP is reviewed annually to enable the City Council to reassess projects in the program. Project expenditures for outlying years beyond fiscal year 2025 are provided in the CIP for planning purposes only and do not reflect a Council commitment of funds.

Capital Improvement Program Process
The CIP is developed as a coordinated effort between the Capital Improvement staff and the Director of Finance.
The annual CIP process begins with a memo and a CIP Project Request form sent out to all City departments requesting proposals for capital projects. New CIP project requests are evaluated and prioritized based on goals and objectives of the City Council, as well as available funding, project need, and the impacts on the operating budget. Some projects have specified funding sources, such as assessment districts, Federal and State grants, or special fees.
The Draft CIP is prepared by Capital Improvement staff and reviewed by the Finance Department before being circulated and approved by the Planning Commission and presented to the Parks & Recreation Commission and the City Council as part of the annual review. The Final CIP budget is presented to the City Council in June and is adopted concurrently with the annual operating budget.

Marina Fund
Fund Description
This fund was established to set aside money from the
General Fund for any Capital Improvement project not
provided for in one of the other funds, such as parks and community facilities improvement projects. The City may transfer General Fund dollars to the Capital Improvement Fund as funding becomes available. Decisions to transfer funds from various funding sources to the Capital
Improvement Fund are made annually by the City Council.
The California SB1 Act included RMRA funding to support maintenance and safety improvements on highways, local
streets and roads, and bridges that do not meet state
performance criteria.
The City receives gas tax funds from the State of California, as provided by the State Street and Highways Code. The gas tax funds are limited to research, planning, construction, improvement, maintenance, and operation of public streets.
The City also uses these funds to pay for maintenance and operation of streetlights and traffic signals.
This fund accounts for the operation, including capital improvements, of the City's Marina and the Fulton Shipyard Boat Ramp. Funds are collected from lease agreements,
berth rentals and launch fees.

Fund Description
The source of money for this fund is the voter approved one- half cent sales tax. Provided the City has complied with the Growth Management Program, each year the City receives
return to source funding from the Contra Costa
Transportation Authority to be used for transportation
improvement and maintenance projects.
The City of Antioch was granted a loan from the State of California for the design and construction of the Brackish Water Desalination Plant.
Fees are collected from developers to fund offsite traffic signals.
The City collects user fees and developer fees to fund offsite water and sewer facility improvements. The fees are placed into one of the following four funds:
Water Fund
Sewer Fund
Water System Improvements Fund
Sewer System Improvements Fund
The National Pollutant Discharge Elimination System was mandated by the Clean Water Act of 1987 to reduce storm water related pollution. The program is funded by a parcel assessment.
In 2013 the City entered into reorganization and a property tax revenue allocation agreement with Contra Costa County for the annexation of the northeast area. Per the agreement, the City will receive property tax revenue from the Contra Costa County for the construction of the infrastructure improvements needed within the northeast annexation area.

Fund Name
Delta Fair Property Fund
American Rescue Plan Act
(ARPA)
Recreation Fund
Fund Description
This fund was created when the City sold property it owned on Delta Fair Boulevard at the City’s western City limits. The property was originally purchased from the State on the condition that it is to be used for public purposes. When it was decided that the property was more suitable for
commercial use and should be sold or leased, the State gave its permission on the condition that the proceeds be used for park purposes.
ARPA is a federal stimulus bill to aid public health and economic recovery from the COVID-19 pandemic. The plan
includes $350 billion in emergency funding for state, local, territorial and tribal governments, known as the Coronavirus State and Local Fiscal Recovery Funds.
This fund provides programs that focus on youth and family enrichment, healthy lifestyles, sports and fitness and services for older adults. The Parks and Recreation Department
maintains a variety of facilities and spaces that are hosted by city programs and are also available for reservation by residents. Recreation Services ensure that all residents have access to the benefits of local parks and recreation.

Water Flood Management
Grant
One Bay Area Grant
(OBAG 2) Program
Grant Description
The storm water management portion of Proposition 1E is designed for projects that manage storm water runoff to reduce flooding and are ready, or nearly ready to proceed to implementation. The Storm Water Flood Management
Grants are being disbursed to local agencies through the Integrated Regional Water Management (IRWM) Grant
program and provide a 50 percent cost match for the project.
The inaugural One Bay Area Grant Program (OBAG 1) was
adopted by MTC in 2012 to guide $827 million in federal funds over the five-year period from 2012-13 through 2016-
17. OBAG 2 is the second round of OBAG funding and is
projected to total roughly $916 million to fund projects from 2017-18 through 2021-22. The OBAG 2 program is divided into a Regional Program, managed by MTC, and County
Program, managed by the nine Bay Area Congestion
Management Agencies (CMAs). The County Program is $386 million over 5 years. Cities and counties can use these funds to invest in:
Local street and road maintenance
Streetscape enhancements
Bicycle and pedestrian improvements
Safe Routes to School projects
Priority Conservation Areas (PCAs)
Transportation planning
California Natural
Resources Agency Grant
This funding was appropriated by the State Legislature in Senate Bill (SB) 129, Chapter 69 (Control Section 19.56 Enacted Budget), which was approved by Governor Newsom
on July 12, 2021.

Implementing, updating and maintaining pavement
management databases
Providing accurate pavement condition data to city
councils, county supervisors or other local decision
makers
Supporting the region’s management of non-
pavement street and road assets, such as signs, storm
drains, curbs and gutters, traffic signals and
streetlights as pilot projects
The purposes of Prop 68 include creating parks, enhancing river parkways, and protecting coastal forests and wetlands.
Prop 68 also provides funding for outdoor access, lower cost coastal accommodation and climate adaptation.
This program funds regional, local and Tribal initiatives through grants to prevent roadway deaths and serious
injuries.
City of Antioch | Capital Improvement Program Overview I-11
Special Funds
Roadway Maintenance Projects
The City of Antioch has approximately 336 centerline miles of roadway within City limits.
As part of the City Pavement Management System Program, the City of Antioch selected a pavement management consultant to perform a Pavement Management Update for the City by inspecting the pavement conditions of arterial, collector and residential streets.
The Pavement Management System Report, which was completed in 2023, rated the City’s overall network condition as a 63 PCI (Pavement Condition Index). The PCI is a value on a rating scale from 0 to 100 (where 100 is equivalent to a new street). A PCI between 60 and 69 is considered “fair”. According to the 2023 Pavement Management System Report, the City’s current backlog (deferred maintenance) is approximately $302 million. Backlog is defined as the unfunded needs to bring the overall network condition to optimum levels (81-82 PCI).
In addition to the City’s funds allocated to the CIP for roadway improvements projects, the City’s Street Maintenance Division also contributes to roadway improvements each fiscal year repairing deteriorating pavement, utility service repairs and utility trenches. The work is performed using a combination of City staff and private contractors.

Development Impact Fees and Park-In-Lieu Fees Projects
On March 25, 2014, City Council adopted the Development Impact Fees and Quimby Act/Park In- Lieu Fees, which became effective April 24, 2014. These fees are one-time charges on new development that are collected and used by the City to cover the cost of capital facilities and infrastructure that are required to serve new growth. Implementation of these future projects is based on the rate of growth, timing of fee collection, and full project funding. The following projects will occur beyond the five-year term of this document:

1. PURPOSE The purpose of the City of Antioch Spill Emergency Response Plan (SERP) is to support a prompt, orderly and effective response to spills (sanitary), reduce spill volumes, and collect information for prevention of future spills. A “spill” in this document is defined, by State Water Board Order No. WQ 2022-0103-DWQ as 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. The SERP provides guidelines for City personnel to follow in responding to, cleaning up, reporting, and properly docu-menting spills that may occur within the City’s service area. This SERP satisfies the State Water Board Order No. WQ 2022-0103-DWQ, which require wastewater collection agencies to have a Spill Emergency Response Plan. Additionally, the SERP outlines procedures for responding to sanitary sewer spill backups into structures as required by the City’s insurer. “Backup” is a term typically used by insurers to describe property damage resulting from exposure and contact to untreated or partially treated sewage. 2. POLICY The City’s employees are required to report all spills from agency owned sewer mains and publicly owned laterals found and to take the appropriate action to secure the spill area, properly report to the appropriate regulatory agencies, relieve the cause of the spill, and ensure that the affected area is cleaned as soon as possible to minimize health hazards to the public and protect the environment. The City’s goal is to respond to sewer system spills as soon as possible following notification. The City will follow reporting procedures regarding sewer spills as set forth by the San Francisco Regional Water Quality Control Board and the State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR). 3. DEFINITIONS AS USED IN THIS SERP ANNUAL REPORT: An Annual Report (previously termed as Collection System Questionnaire in previous State Water Board Order No. 2006-0003-DWQ) is a mandatory report in which the City provides a calendar-year update of its efforts to prevent spills. BASIN PLAN: A Basin Plan is a water quality control plan specific to a Regional Water Quality Control Board (Regional Water Board), that serves as regulations to: (1) define and designate beneficial uses of surface and groundwaters, (2) establish water quality objectives for protection of beneficial uses, and (3) provide implementation measures. BENEFICIAL USES: The term “Beneficial Uses” is a Water Code term, defined as the uses of the waters of the State that may be protected against water quality degradation. Examples of beneficial uses include but are not limited to, municipal, domestic, agricultural, and industrial supply; power generation; recreation; aesthetic enjoyment; navigation; and preser-vation and enhancement of fish, wildlife, and other aquatic resources or preserves. CALIFORNIA INTEGRATED WATER QUALITY SYSTEM (CIWQS): CIWQS is the statewide database that provides for man-datory electronic reporting as required in State and Regional Water Board-issued waste discharge requirements. DATA SUBMITTER: A Data Submitter is an individual designated and authorized by the City’s Legally Responsible Official to enter spill data into the online CIWQS Sanitary Sewer System Database. A Data Submitter does not have the authority of a Legally Responsible Official to certify reporting entered into the online CIWQS Sanitary Sewer System Database.

Page 5 of 48 DRAINAGE CONVEYANCE SYSTEM: A drainage conveyance system is a publicly- or privately-owned separate storm sewer system, including but not limited to drainage canals, channels, pipelines, pump stations, detention basins, infiltration basins/facilities, or other facilities constructed to transport stormwater and non-stormwater flows. ENVIRONMENTALLY SENSITIVE AREA: An environmentally sensitive area is a designated agricultural and/or wildlife area identified to need special natural landscape protection due to its wildlife or historical value. EXFILTRATION: Exfiltration is the underground exiting of sewage from a sanitary sewer system through cracks, offset or separated joints, or failed infrastructure due to corrosion or other factors. FOG – Fats, Oils, and Grease: Refers to fats, oils, and grease typically associated with food preparation and cooking activities that can cause blockages in the sanitary sewer system. HYDROLOGICALLY CONNECTED: Two waterbodies are hydrologically connected when one waterbody flows, or has the potential to flow, into the other waterbody. For the purpose of the SWRCB Order, groundwa-ter is hydrologically connected to a surface water when the groundwa-ter feeds into the surface water. See image, right. The surface water-body in this example is termed a gaining stream as it gains flow from surrounding groundwater. LATERAL (INCLUDING LOWER AND UPPER LATERAL): A lateral is an un-derground segment of smaller diameter pipe that transports sewage from a customer’s building or property (residential, commercial, or industrial) to the City’s main sewer line in a street or easement. Upper and lower lateral boundary definitions are subject to local jurisdictional codes and ordinances, or pri-vate system ownership. A lower lateral is the portion of the lateral located between the sanitary sewer system main, and either the property line, sewer clean out, curb line, established utility easement boundary, or other jurisdictional loca-tions. An upper lateral is the portion of the lateral from the property line, sewer clean out, curb line, established utility easement boundary, or other jurisdictional locations, to the building or property. LEGALLY RESPONSIBLE OFFICIAL: A Legally Responsible Official is an official representative, designated by the City, with authority to sign and certify submitted information and documents required by State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR). MAINLINE SEWER: Refers to City wastewater collection system piping downstream of the sewer laterals that is not a private sewer lateral connection to a building. MAINTENANCE HOLE OR MANHOLE: Refers to an engineered structure that is intended to provide access to a sanitary sewer for maintenance and inspection NOTIFICATION OF A SPILL: Refers to the time at which the City becomes aware of a spill event through observation or notification by the public or other source. NUISANCE: For the purpose of the State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR), a nuisance, as defined in Water Code section 13050(m), is anything that meets all of the following requirements: • Is injurious to health, or is indecent or offensive to the senses, or an obstruction to the free use of property, so as to interfere with the comfortable enjoyment of life or property; • Affects at the same time an entire community or neighborhood, or any considerable number of persons, although the extent of the annoyance or damage inflicted upon individuals may be unequal; and
City of Antioch Spill Emergency Response Plan Draft 5-25-23 © 2004-2023 DKF Solutions Group, LLC. All rights reserved. Page 6 of 48 • Occurs during, or as a result of, the treatment or disposal of wastes. PREVENTATIVE MAINTENANCE: Refers to maintenance activities intended to prevent failures of the wastewater collection system facilities (e.g. cleaning, CCTV, inspection). PRIVATE LATERAL SEWAGE SPILL – Spills that are caused by blockages or other problems within a privately-owned lateral. PRIVATE SANITARY SEWER SYSTEM: A private sanitary sewer system is a sanitary sewer system of any size that is owned and/or operated by a private individual, company, corporation, or organization. A private sanitary sewer system may or may not connect into a publicly owned sanitary sewer system. PRIVATE SEWER LATERAL: A private sewer lateral is the privately-owned lateral that transports sewage from private property(ies) into a sanitary sewer system. POTENTIAL TO DISCHARGE, POTENTIAL DISCHARGE: Potential to Discharge, or Potential Discharge, means any exiting of sewage from a sanitary sewer system which can reasonably be expected to discharge into a water of the State based on the size of the sewage spill, proximity to a drainage conveyance system, and the nature of the surrounding environ-ment. RECEIVING WATER: A receiving water is a water of the State that receives a discharge of waste. SANITARY SEWER SYSTEM: A sanitary sewer system is a system that is designed to convey sewage, including but not limited to, pipes, manholes, pump stations, siphons, wet wells, diversion structures and/or other pertinent infrastructure, upstream of a wastewater treatment plant headworks, including: • Laterals owned and/or operated by the City; • Satellite sewer systems; and/or • Temporary conveyance and storage facilities, including but not limited to temporary piping, vaults, construction trenches, wet wells, impoundments, tanks, and diversion structures. For purpose of the State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR), sanitary sewer systems include only systems owned and/or operated by the City. SATELLITE SEWER SYSTEM: A satellite sewer system is a portion of a sanitary sewer system owned or operated by a different owner than the owner of the downstream wastewater treatment facility ultimately treating the sewage. SEWAGE: Sewage, and its associated wastewater, is untreated or partially treated domestic, municipal, commercial and/or industrial waste (including sewage sludge), and any mixture of these wastes with inflow or infiltration of storm-water or groundwater, conveyed in a sanitary sewer system. SEWER BACKUP A sanitary sewer spill resulting from a sanitary sewer system overflow, operational failure, and/or infra-structure failure in a publicly owned sewer system, with an appearance point and subsequent discharge into a structure. SPILL: A spill is a discharge of sewage from any portion of a sanitary sewer system due to a sanitary sewer system over-flow, operational failure, and/or infrastructure failure. Exfiltration of sewage is not considered to be a spill under the State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR) if the exfiltrated sewage remains in the subsurface and does not reach a surface water of the State.

Page 7 of 48 • Category 1 Spill: A Category 1 spill is a spill of any volume of sewage from or caused by a sanitary sewer system regulated under the State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR) that results in a discharge to: o A surface water, including a surface water body that contains no flow or volume of water; or o A drainage conveyance system that discharges to surface waters when the sewage is not fully captured and returned to the sanitary sewer system or disposed of properly. Any spill volume not recovered from a drainage conveyance system is considered a discharge to surface water, unless the drainage conveyance system discharges to a dedicated stormwater infiltration basin or facility. A spill from a City-owned and/or operated lateral that discharges to a surface water is a Category 1 spill; the City shall report all Category 1 spills per section 3.1 of Attachment E1 (Notification, Monitoring, Reporting and Recordkeeping Requirements) of State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR). • Category 2 Spill A Category 2 spill is a spill of 1,000 gallons or greater, from or caused by a sanitary sewer system regulated under the State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR) that does not discharge to a surface water. A spill of 1,000 gallons or greater that spills out of a lateral and is caused by a failure or blockage in the sanitary sewer system, is a Category 2 spill. • Category 3 Spill A Category 3 spill is a spill of equal to or greater than 50 gallons and less than 1,000 gallons, from or caused by a sanitary sewer system regulated under the State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR) that does not discharge to a surface water. A spill of equal to or greater than 50 gallons and less than 1,000 gallons, that spills out of a lateral and is caused by a failure or blockage in the sanitary sewer system is a Category 3 spill. • Category 4 Spill A Category 4 spill is a spill of less than 50 gallons, from or caused by a sanitary sewer system regulated under the State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR) that does not discharge to a surface water. A spill of less than 50 gallons that spills out of a lateral and is caused by a failure or blockage in the sanitary sewer system is a Category 4 spill. TRAINING: Training is in-house or external education and guidance needed that provides the knowledge, skills, and abilities to comply with the State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR). WASH DOWN WATER: Wash down water is water used to clean a spill area. WASTE: Waste, as defined in Water Code section 13050(d), includes sewage and any and all other waste substances, liquid, solid, gaseous, or radioactive, associated with human habitation, or of human or animal origin, or from any producing, manufacturing, or processing operation, including waste placed within containers of whatever nature prior to, and for purposes of, disposal. WATERS OF THE STATE: Waters of the State are surface waters or groundwater within boundaries of the state as defined in Water Code section 13050(e), in which the State and Regional Water Boards have authority to protect beneficial uses. Waters of the State include, but are not limited to, groundwater aquifers, surface City of Antioch Spill Emergency Response Plan Draft 5-25-23 © 2004-2023 DKF Solutions Group, LLC. All rights reserved. Page 8 of 48 waters, saline waters, natural washes and pools, wetlands, sloughs, and estuaries, regardless of flow or whether water exists during dry conditions. Waters of the State include waters of the United States. WATERS OF THE UNITED STATES: Waters of the United States are surface waters or waterbodies that are subject to federal jurisdiction in accordance with the Clean Water Act. WATER QUALITY OBJECTIVE: A water quality objective is the limit or maximum amount of pollutant, waste constituent or characteristic, or parameter level established in statewide water quality control plans and Regional Water Boards’ Basin Plans, for the reasonable protection of beneficial uses of surface waters and groundwater and the prevention of nuisance. 4. STATE REGULATORY REQUIREMENTS FOR ELEMENT 6, SPILL EMERGENCY RESPONSE PLAN The Sewer System Management Plan (SSMP) must include an up to date Spill Emergency Response Plan (SERP) to ensure prompt detection of and response to spills to reduce spill volumes and collect information for prevention of future spills. The SERP must include 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 State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR), State law and regulations, and applicable Regional Water Board Orders; • Ensure that appropriate staff and contractors implement the SERP and are appropriately trained; • Address emergency system operations, traffic control and other necessary response activities; • Contain a 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 drainage conveyance system; • Clean the spill area and drainage conveyance system in a manner that does not inadvertently impact bene-ficial 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 agen-cies/departments prior, during, and after a spill event; • Conduct post-spill assessments of spill response activities; • Document and report spill events as required in State Water Board Order No. WQ 2022-0103-DWQ (SSS-WDR); and • Annually, review and assess effectiveness of the Spill Emergency Response Plan, and update it as needed.

5. SPILL EMERGENCY RESPONSE PLAN OBJECTIVES The Spill Emergency Response Plan includes measures to protect public health and the environment. The City will respond to spills from its system(s) in a timely manner that minimizes water quality impacts and nuisance by: • Immediately stopping the spill and preventing/minimizing a discharge to waters of the State; • Intercepting sewage flows to prevent/minimize spill volume discharged into waters of the State; • Thoroughly recovering, cleaning up and disposing of sewage and wash down water; and • Cleaning publicly accessible areas while preventing discharges to waters of the State. Additionally, City Staff will: • Work safely; • Properly document each spill event in a separate file including photos and/or video where applicable; • Collect information for prevention of future spills; • Minimize public contact with the spilled wastewater; • Mitigate the impact of the spill; • Meet the regulatory reporting requirements; • Evaluate the causes of failure related to spills; • Perform post-spill response evaluation for adherence to procedures and effectiveness of response; and • Revise response procedures, modify maintenance practices or provide additional training based on the re-sults from the debrief and failure analysis of spills, if needed. 6. SPILL DETECTION AND NOTIFICATION ref. State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR), ATTACHMENT D, Element 6, Page D-6 The processes that are employed to notify the City of the occurrence of a spill include: observation by the public, receipt of an alarm, or observation by City staff during the normal course of their work. 6.1 LIFT STATION ALARMS The City operates 1 wastewater lift stations. In the event of a station failure the SCADA alarm system is activated and the City is contacted. To prevent spills, wastewater from the wet well can either be pumped into a vacuum truck for disposal to a nearby sanitary sewer manhole or bypassed around the station into the sanitary sewer system. 6.2 PUBLIC OBSERVATION Public observation is the most common way that the City is notified of blockages and spills. Contact numbers and information for reporting sewer spills and backups are on the City’s website: https://www.antiochca.gov/public-works-department/sewer-collections-npdes/. The City’s telephone number for reporting sewer problems during business hours is (925) 779-6950. The City’s telephone number for reporting sewer problems after business hours is (925) 778-2441.

Page 10 of 48 • Normal Work Hours: When a sewer service request is made during normal work hours, Public Works Reception receives the call, takes the information from the caller, and generates a Work Request in CityWorks. Work Request is emailed and a notification is sent to the Collections tablet with the Col-lections Crew, and an alert is sent to the Collections Supervisor or, if not available, Collection Systems Superintendent. The Collections Crew will perform an investigation and note findings and actions taken, if any, and create a Work Order based on the results of the investigation. If the service request is a spill, the Spill Emergency Response Workbook will also be completed. • After Hours: After hours calls are automatically forwarded to Police Dispatch at (925) 778-2441. Dis-patch notifies the on-call Collections Crew member. The on call Collections Crew member will per-form an investigation and note findings and actions taken, if any, and create a Work Order based on the results of the investigation. If the service request is a spill, the Spill Emergency Response Work-book will also be completed. When calls are received, either during normal work hours or after hours, the individual receiving the call will collect and include in the spill event file, at a minimum, the following information to record the complaint: • Date, time, and method of notification, • Date and time the complainant first noticed the spill, if available, • Narrative description of the complaint, including any information the caller provided regarding whether the spill has reached surface waters or a drainage conveyance system, if available, • Complainant’s contact information, if available, and • Final resolution of the complaint. If the spill or backup is not in the City’s service area the individual receiving the call provides the customer with the contact information for the responsible agency, and then notifies that agency. 6.3 CITY STAFF OBSERVATION City staff conducts periodic inspections of its sewer system facilities as part of their routine activities. Any prob-lems noted with the sewer system facilities are reported to appropriate City staff that, in turn, responds to emer-gency situations. Work orders are issued to correct non-emergency conditions. 6.4 CONTRACTOR OBSERVATION Contractors working on the City sewer system will be informed of contractor spill response procedures. Contrac-tors working on behalf of property owners will be provided spill response information by City Hall Building De-partment and/or the Engineering Department when they pull a permit. The following procedures are to be fol-lowed in the event that a contractor/plumber causes or witnesses a sanitary sewer spill. If the contrac-tor/plumber causes or witnesses a spill they should: 1. Immediately notify the City at during business hours is (925) 779-6950 or after business hours is (925) 778-2441 and provide the following information if available: a. Date, time contractor first noticed the spill b. Description of the contractor’s observation, including any information regarding whether the spill has reached surface waters or a drainage conveyance system c. Contractor’s contact information City of Antioch Spill Emergency Response Plan Draft 5-25-23 © 2004-2023 DKF Solutions Group, LLC. All rights reserved. Page 11 of 48
2. Protect storm drains. 3. Protect the public. 4. Direct ALL media and public relations requests to the City Attorney’s Office. 6.5 NO OBSERVATION If there are no witnesses or no call was received for a spill, the City staff will contact nearby residences or business owners in the vicinity of the spill, in an attempt to obtain information that brackets a given start time that the spill began. This information will be collected and documented on the Sanitary Sewer Spill Report in the Sanitary Sewer Spill/Backup Response Workbook. 7. SPILL RESPONSE PROCEDURES (Ref. State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR), ATTACHMENT D Element 6 page D-6) 7.1 SEWER SPILL/BACKUP RESPONSE SUMMARY The City will respond to spills as soon as feasible following notification of a spill/backup. If it is not possible that the spill/backup is due to a failure in the City-owned/maintained sewer lines the Collec-tions Crew performs the following: • Follows the instructions in the Sanitary Sewer Spill/Backup Response Workbook. • If the customer is not home the Collections Crew completes the Door Hanger and leaves it on the cus-tomer’s door. • If the customer is home the Collections Crew: o Explains that the blockage is in the customer’s lateral and the City does not have legal authority to maintain or perform work on privately owned laterals. o Recommends to the customer that they hire a licensed contractor to clear their line. o Gives the customer the Your Responsibilities as a Private Property Owner pages from the Sanitary Sewer Spill/Backup Response Workbook. If it is possible that the spill/backup is due to a failure in the City-owned/maintained sewer lines the Collections Crew: • Follows the instructions in the Sanitary Sewer Spill/Backup Response Workbook. • Notifies Collection Systems Superintendent or the Collection Systems Supervisor of the incident. • Relieves blockage and cleans impacted areas. • Forwards the completed Sanitary Sewer Spill/Backup Response Workbook to the Collection Systems Su-pervisor. The Collection Systems Superintendent or designee performs required regulatory reporting in accordance with the Sanitary Sewer Spill/Backup Response Workbook’s Regulatory Reporting section. If the overflow has impacted private property, the Collections Crew:
City of Antioch Spill Emergency Response Plan Draft 5-25-23 © 2004-2023 DKF Solutions Group, LLC. All rights reserved. Page 12 of 48 • Follows the instructions in the Sanitary Sewer Spill/Backup Response Workbook. • Provides the customer with forms and information as indicated in the Sanitary Sewer Spill/Backup Re-sponse Workbook. • Forwards the completed Sanitary Sewer Spill/Backup Response Workbook to the Collection Systems Su-pervisor. The Collection Systems Supervisor notifies the City Attorney’s Office of incident. The City Attorney’s Office or designee: • Reviews incident reports, claim form and other incident information and forwards, as appropriate, to Municipal Pooling Authority (MPA). • Communicates with claimant as appropriate. • Communicates with Municipal Pooling Authority (MPA) to adjust and administer the claim to closure. • Properly documents in writing all activities and communications before approving the final event file. 7.2 FIRST RESPONDER PRIORITIES The first responder’s priorities are: • Prompt response to spills. • To follow safe work practices. • To respond promptly with the appropriate and necessary equipment. • To reduce spill volume and contain the spill wherever feasible. • To restore the flow as soon as practicable. • To minimize public access to and/or contact with the spilled sewage. • To promptly notify the Collection Systems Superintendent in event of a spill needing additional resources, and/or impacting environmentally sensitive areas. • To return the spilled sewage to the sewer system. • To restore the area to its original condition (or as close as possible). Collect information for the preven-tion of future spills. • Properly document the spill and response activities on the forms provided in the Sanitary Sewer Spill/Backup Response Workbook, including photos and/or video where practicable. 7.3 SAFETY The first responder is responsible for following safety procedures at all times. Special safety precautions must be observed when performing sewer work. There may be times when City personnel responding to a sewer system event are not familiar with potential safety hazards peculiar to sewer work. In such cases it is appropriate to take the time to discuss safety issues, consider the order of work, and check safety equipment before beginning re-sponse activities. If the first responders encounter access restrictions or unsafe conditions that prevent its compliance with spill response requirements or monitoring requirements in State Water Board Order No. WQ 2022-0103-DWQ City of Antioch Spill Emergency Response Plan Draft 5-25-23 © 2004-2023 DKF Solutions Group, LLC. All rights reserved. Page 13 of 48 (SSSWDR), the City provides written documentation of access restrictions and/or safety hazards in the corre-sponding required report. 7.4 INITIAL RESPONSE The first responder must respond to the site of the spill/backup and visually check for potential sewer stoppages. The first responder will: • Note arrival time at the site of the spill/backup. • Verify the existence of a public sewer system spill or backup. • Identify and assess the affected area and extent of spill. • Assess the spill location(s) and spread using photography, global positioning system (GPS), and other best available tools. • Contact caller if time permits. • Document the spill according to the requirements described in Section 10 of this SERP, including taking photos and/or videos of overflowing manhole(s)/cleanout(s). • Take steps to contain, recover, and return the spill to the sanitary sewer as feasible. For procedures refer to the Sanitary Sewer Spill/Backup Response Workbook. • Protect surface waters to the extent practicable. For procedures refer to the Sanitary Sewer Spill/Backup Response Workbook. • Implement pre-planned coordination and collaboration with storm drain agencies and other utility agen-cies/departments prior, during, and after a spill event. 7.5 INITIATE SPILL CONTAINMENT MEASURES The first responder will attempt to contain as much of the spilled sewage as possible using the following steps: • Determine the immediate destination of the overflowing sewage. • Plug storm drains using air plugs, sandbags, and/or plastic mats to contain the spill, whenever appropriate. If spilled sewage has made contact with the storm drainage system, attempt to contain the spilled sewage by plugging downstream storm drainage facilities. • Contain/direct the spilled sewage using dike/dam or sandbags. • Vacuum retrieve sewage whenever practicable. • Pump around the blockage/pipe failure. Containment efforts will be documented. For procedures refer to the Sanitary Sewer Spill/Backup Response Workbook. 7.6 RESTORE FLOW Using the appropriate cleaning equipment, set up downstream of the blockage and hydro-clean upstream from City of Antioch Spill Emergency Response Plan Draft 5-25-23 © 2004-2023 DKF Solutions Group, LLC. All rights reserved. Page 14 of 48 a clear manhole. Attempt to remove the blockage from the system and observe the flows to ensure that the blockage does not reoccur downstream. If the blockage cannot be cleared within a reasonable time from arrival, or sewer requires construction repairs to restore flow, then initiate containment and/or bypass pumping. If other assistance is required, immediately contact the Collection Systems Superintendent. For procedures refer to the Sanitary Sewer Spill/Backup Response Workbook. 7.7 EQUIPMENT This section provides a list of specialized equipment that may be used to support this Spill Emergency Response Plan. • Closed Circuit Television (CCTV) Inspection Unit – A CCTV Inspection Unit is required to determine the root cause for all spills from gravity sewers. • Camera -- A digital or disposable camera (photo, video or phone) is required to record the conditions upon arrival, during clean up, and upon departure. • Emergency Response Trucks -- A utility body pickup truck, or open bed is required to store and transport the equipment needed to effectively respond to sewer emergencies. The equipment and tools will include containment and clean up materials. • Portable Generators, Portable Pumps, Piping, and Hoses – Equipment used to bypass pump, divert, or power equipment to mitigate a spill. • Combination Sewer Cleaning Trucks -- Combination high velocity sewer cleaning trucks with vacuum tanks are required to clear blockages in gravity sewers, vacuum spilled sewage, and wash down the impacted area following the spill event. • Rodding (snake) equipment for responding to lateral blockages. • Air plugs, sandbags and plastic mats • Spill Sampling Kits • Portable Lights Standard operating procedures for equipment that may be necessary in the event of a sanitary sewer overflow or backup can be found in the City server. 8. RECOVERY AND CLEANUP (Ref. State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR), Element 6, AT-TACHMENT D, Page D-6) The recovery and cleanup phase begins immediately after the flow has been restored and the spilled sewage has been contained to the extent possible. The spill recovery and cleanup procedures are described in the following sections.

8.1 ESTIMATE THE FLOW AND VOLUME OF SPILLED SEWAGE A variety of approaches exist for estimating the volume of a sanitary sewer spill. The Collections Crew members should use the method most appropriate to the sewer overflow in question and reference the Sanitary Sewer Spill/Backup Response Workbook which provides four (4) methods: • Eyeball Estimation Method • Duration and Flow Rate Calculation Method • Area/Volume Method • Upstream Connections Method In addition, the following will be documented on the Sewer Spill Report form: 1. Description, photographs, and GPS coordinates of the system location where the spill originated. If a single spill event results in multiple appearance points, provide GPS coordinates for the appearance point closest to the failure point and describe each additional appearance point in the spill appearance point explanation field; 2. Estimated total spill volume exiting the system; 3. Description and photographs of the extent of the spill and spill boundaries; 4. Did the spill reach a drainage conveyance system? If yes: • Description of the drainage conveyance system transporting the spill; • Photographs of the drainage conveyance system entry location(s); • Estimated spill volume that reached the drainage conveyance system; • Estimated spill volume fully recovered from the drainage conveyance system; • Estimated spill volume remaining within the drainage conveyance system • Estimated spill volume discharged to a groundwater infiltration basin or facility, if applicable; • Estimated spill travel time from the point of entry into the drainage conveyance system to the point of discharge into the receiving water. 5. Estimated total spill volume recovered. 8.2 RECOVERY OF SPILLED SEWAGE Vacuum up and/or pump the spilled sewage and wash down water and discharge it back into the sanitary sewer system. Thoroughly recover and dispose of sewage and wash down water. 8.3 CLEAN-UP AND DISINFECTION Clean up procedures will be implemented to reduce the potential for human health issues and adverse environ-mental impacts associated with a spill event. The procedures described are for dry weather conditions and will be modified as required for wet weather conditions. Where cleanup is beyond the capabilities of City staff, a cleanup contractor will be used.

Page 16 of 48 Private Property City crews are responsible for the cleanup when the property damage is minor in nature and is outside of private building dwellings, such as in front, side and backyards, easements, etc. In all other cases, affected property owners can call a water damage restoration contractor to complete the cleanup and restoration. If the overflow into property is the definite cause of City system failure, the property owner can call out a water damage restoration contractor to complete the cleanup and restoration. In both cases, property owners may submit a claim form. Hard Surface Areas Collect all signs of sewage solids and sewage-related material either by protected hand or with the use of rakes and brooms. Wash down the affected area with clean water and/or deozyme or similar non-toxic biodegradable surface disinfectant until the water runs clear. The flushing volume will be approxi-mately three times the estimated volume of the spill. Take steps to contain and vacuum up the wastewater. Allow area to dry. Repeat the process if additional cleaning is required. Landscaped and Unimproved Natural Vegetation Collect all signs of sewage solids and sewage-related material either by protected hand or with the use of rakes and brooms. Wash down the affected area with clean water until the water runs clear. The flushing volume will be approximately three times the estimated volume of the spill. Either contain or vacuum up the wash water so that none is released. Allow the area to dry. Repeat the process if addi-tional cleaning is required. Natural Waterways The Department of Fish and Wildlife will be notified by CalOES for spills greater than or equal to 1,000 gallons. For spills less than 1,000 gallons, contact Contra Costa County Environmental Health for direc-tion. Wet Weather Modifications Collect all signs of sewage solids and sewage-related material either by protected hand or with the use of rakes and brooms. Omit flushing and sampling during heavy storm events (i.e., sheet of rainwater across paved surfaces) with heavy runoff where flushing is not required and sampling would not provide meaningful results. 8.4 PUBLIC NOTIFICATION Signs will be posted and barricades put in place to keep vehicles and pedestrians away from contact with spilled sewage. Contra Costa County Environmental Health instructions and directions regarding placement and lan-guage of public warnings will be followed. Additionally, the Collection Systems Superintendent will use their best judgment regarding supplemental sign placement in order to protect the public and local environment. Signs will not be removed until directed by Contra Costa County Environmental Health or the Collection Systems Superin-tendent. Creeks, streams and beaches that have been contaminated as a result of a spill will be posted at visible access locations until the risk of contamination has subsided to acceptable background bacteria levels. Document the number and location of posted signs. The area and warning signs, once posted, will be checked every day to ensure that they are still in place. Photographs of sign placement will be taken.

State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR), Element 6, Attachment A - DEFINITIONs page A-5, Attachment E1 2.3 through 2.4 pages E1-5 through E1-8) 9.1 SURFACE WATERS OF CONCERN The following waters of the State are in the City’s service area: • Sacramento River Delta • Lake Alhambra • San Joaquin River • East Antioch Creek • West Antioch Creek • Marklee Creek • Los Medanos wasteway • Black Diamond Detention Basin A and B 9.2 WATER QUALITY SAMPLING AND TESTING For sewage spills in which an estimated 50,000 gallons or greater are discharged into a surface water, the City will conduct the following water quality sampling as soon as possible but no later than 18 hours after the City’s knowledge of a potential discharge to a surface water. Collect one water sample, each day of the duration of the spill, at: • The DCS-001 location as described in section 9.7 (Receiving Water Sampling Locations) below, if sewage discharges to a surface water via a drainage conveyance system; and/or • Each of the three receiving water sampling locations in section 9.7 (Receiving Water Sampling Locations) below; If the receiving water has no flow during the duration of the spill, the City must report “No Sampling Due To No Flow” for its receiving water sampling locations. The Collections Crew will collect water quality samples in accordance with State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR). The Collections Crew collecting the samples will complete the Chain of Custody prior to transferring ownership of the samples to the McCampbell Analytical lab. The McCampbell Analytical lab shall analyze the collected receiving water samples for the following constituents: • Ammonia, and City of Antioch Spill Emergency Response Plan Draft 5-25-23 © 2004-2023 DKF Solutions Group, LLC.

Based on multiple tube fermentation technique; equivalent test results based on other analytical techniques, as specified in the National Primary Drinking Water Regulation, 40 CFR, Part 141.21(f), revised June 10, 1992, are acceptable. g. Numeric values are from Part 3 of the Water Quality Control Plan for Inland Surface Waters, Enclosed Bays, and Estuaries of California based on Section 7958 of Title 17 of the California Code of Regulations, 69FR 67217 et seq., and 40 CFR Part 131.41 (effective date December 16, 2004). The Enterococcus objective applies to marine and estuarine waters where the salin-ity is greater than 1 part per thousand more than 5 percent of the time. The E. coli objective ap-plies to freshwaters where the salinity is equal to or less than 1 part per thousand 95 percent or more of the time. The geometric mean for enterococcus and E. coli is computed weekly for all samples in a 6-week interval. There is no fecal coliform objective to protect water contact recre-ation for inland surface waters, enclosed bays, or estuaries, but a fecal coliform objective pro-tecting this use remains in the California Ocean Plan. The STV is the statistical threshold value and shall not be exceeded by more than 10 percent of the samples collected in a calendar month. Dependent on the receiving water(s), sampling of bacterial indicators shall be sufficient to determine post-spill (after the spill) compliance with the water quality objectives and bacterial standards of the California Ocean Plan or the California Inland Surface Water Enclosed Bays, and Estuaries Plan, including the frequency and/or number of post-spill receiving water samples as may be specified in the applicable plans.
City of Antioch Spill Emergency Response Plan Draft 5-25-23 © 2004-2023 DKF Solutions Group, LLC. All rights reserved. Page 19 of 48 The City shall collect and analyze additional samples as required by the applicable Regional Water Board Execu-tive Officer or designee. 9.3 LAB SELECTION Analytical Lab Samples collected for spill response and background monitoring purposes will be analyzed at the McCampbell Analytical lab, which is accredited through the California State Water Resources Control Board Environmental Laboratory Accreditation Program (ELAP). ELAP provides evaluation and accreditation of environmental testing laboratories to ensure the quality of analytical data used for regulatory purposes to meet the requirements of the State's drinking water, wastewater, shellfish, food, and hazardous waste programs. The State agencies that mon-itor the environment use the analytical data from these accredited labs. The ELAP-accredited laboratories have demonstrated capability to analyze environmental samples using approved methods. Getting Samples to the Lab At all times, sample hold times identified below will be observed in accordance with the following: Analytical Parameter Maximum Holding Time Required Container Type Required Preservative Mini-mum Amount Ammonia (NH3 as N); SM 4500NH3 B/C or B/G 28 days Plastic / Glass H2SO4 pH <2 +0-6°C 200 mL Coliform, Total / Fecal; SM 9221 B/E 8 hours – wastewater/storm-water 30 hours – drinking water Plastic (sterile) Na2S2O3 + 0-10°C; No regulatory temp. req. for drinking water) 100 mL Coliform, Total / E.Coli; SM 9223 B (Present/Ab-sent or Quantitray) 8 hours Plastic (sterile) Na2S2O3 + 0-10°C; No regulatory temp. req. for DW 100 mL Enterococcus by Enter-olert 8 hours Plastic (sterile) Na2S2O3 + 0-10°C 100 mL Once samples are collected, they will be transported by the Collections Crew to the lab to be processed. 9.4 WATER QUALITY ANALYSIS SPECIFICATIONS Spill monitoring must be representative of the monitored activity (40 Code of Federal Regulations section 122.41(j)(1)). Sufficiently Sensitive Methods Sample analysis must be conducted according to sufficiently sensitive test methods approved under 40 Code of Federal Regulations Part 136 for the sample analysis of pollutants. For the purposes of State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR), a method is sufficiently sensitive when the minimum level of the analytical method approved under 40 Code of Federal Regulations Part 136 is at or below the receiving water pollutant criteria.
City of Antioch Spill Emergency Response Plan Draft 5-25-23 © 2004-2023 DKF Solutions Group, LLC. All rights reserved. Page 20 of 48 Environmental Laboratory Accreditation Program-Accredited Laboratories The analysis of water quality samples required per State Water Board Order No. WQ 2022-0103-DWQ (SSS-WDR) must be performed by a laboratory that has accreditation pursuant to Article 3(commencing with section 100825) of Chapter 4 of Part 1 of Division 101 of the Health and Safety Code. (Water Code section 13176(a).) The State Water Board accredits laboratories through its Environmental Laboratory Accreditation Program (ELAP). 9.5 RECEIVING WATER SAMPLING LOCATIONS Receiving water samples shall be collected at the following locations. Sampling of Flow in Drainage Conveyance System (DCS) Prior to Discharge Sampling Location Sampling Location Description DCS-001 A point in a drainage conveyance system before the drainage con-veyance system flow discharges into a receiving water. Receiving Surface Water Sampling (RSW)1 Sampling Location Sampling Location Description RSW-001: Point of Discharge A point in the receiving water where sewage initially enters the re-ceiving water. RSW-001U: Upstream of Point of Discharge A point in the receiving water, upstream of the point of sewage dis-charge, to capture ambient conditions absent of sewage discharge impacts. RSW-001D: Downstream of Point of Discharge A point in the receiving water, downstream of the point of sew-age discharge, where the spill material is fully mixed with the receiv-ing water. 9.6 STREAM VELOCITY MEASUREMENTS If sampling is performed after the spill has stopped, the velocity of the impacted surface water must be deter-mined to estimate spill travel time and select an accurate Downstream sample location. One way to measure the spill travel time is to use a velocity probe (such as a Global Water FP111-S Flow Probe) to determine the rate of flow in the water body. In cases where a water velocity probe is used, the manufacturer’s instructions will be followed. 1 The City must use its best professional judgment to determine the upstream and downstream distances based on re-ceiving water flow, accessibility to upstream/downstream waterbody banks, and size of visible sewage plume.

9.7 SAMPLE TYPES Grab Samples Grab samples are appropriate for the characterization of surface waters at a particular time and place, to provide information about minimum and maximum concentrations, and to allow for the collection of variable sample volume. Grab samples may be collected directly into the sample container, or a clean decontaminated intermediate con-tainer may be used if a wading sample is not possible or safe. If an intermediate container is used, when in the field, double rinse the sampling device (bucket, automatic sampler) with sample water prior to collecting the sam-ple and be sure to discard rinse water downstream of where sample will be collected. If samples are collected in a bucket and distributed into a consolidation collection container, swirl the contents of the bucket as it is being poured into the consolidation collection container to avoid settling of solids (and pour in back-and-forth pattern – e.g., 1-2-3-3-2-1). • Grab Sample: A grab sample is defined as an individual sample collected at a given time. Grab samples represent only the condition that exists at the time the sample is collected (US EPA 1977). • Surface Grab Sample: A sample collected at the water surface (i.e., skimming) directly into the sample container or into an intermediate container such as a clean bucket. A single or discrete sample collected at a single location. Field Blanks Field Blanks are used to evaluate the potential for contamination of a sample by site contaminants from a source not associated with the sample collected (e.g., airborne dust, etc.). Sterile, deionized water is taken into the field in a sealed container. This is the stock water. The stock water is then poured into the sample container. The containers and sample submission forms are labeled as “Field Blank.” The same template selected for the test samples should be used. Field blanks are subject to the same holding time limitations as samples. The appropriate FIELD QC box on the sample Chain of Custody form should be checked. 9.8 SAMPLE LABELING AND CHAIN OF CUSTODY PROCEDURES At a minimum, the following grab samples will be collected: • Field Blank: See Section 9.7 for discussion. • Upstream: A point in the receiving water, upstream of the point of sewage discharge, to capture ambi-ent conditions absent of sewage discharge impacts. • Source: A point in the receiving water where sewage initially enters the receiving water. See Section 9.6 for information on determining velocity of the surface water in order to determine the Source sample location. • “Downstream” of spill: A point in the receiving water, downstream of the point of sewage dis-charge, where the spill material is fully mixed with the receiving water. This location will vary with the velocity of the surface water to be sampled (see Section 9.6). • A point in a drainage conveyance system before the drainage conveyance system flow discharges into a receiving water.
City of Antioch Spill Emergency Response Plan Draft 5-25-23 © 2004-2023 DKF Solutions Group, LLC. All rights reserved. Page 22 of 48 Sample labels shall be completed for each sample, using waterproof ink, as described in Section 9.5. Photos or video of each sample location will be taken, properly labeled with date, time, and view direction and a map of the photo locations completed. Photos and videos shall include relevant landmarks to identify sampling locations and their surroundings. Due to the evidentiary nature of samples collected during enforcement investigations, possession must be trace-able from the time the samples are collected until they are analyzed. To maintain and document sample posses-sion, a Surface Water Sample Chain of Custody Record (see Sewer Spill/Backup Response Workbook) must be completed. A sample is under custody if: • It is in your possession, or • It is in your view, after being in your possession, or • It was in your possession and under your control to prevent tampering, or • It is in a designated secure area. As few people as possible should handle samples. The person taking the samples is personally responsible for the care and custody of the samples collected until they are transferred or dispatched properly. Samples are accompanied by a chain of custody record. When transferring the possession of samples, the indi-viduals relinquishing and receiving will sign, date, and note the time on the record. This record documents sample custody transfer from the sampler, often through another person, to the analyst at the laboratory. The samples are typically transferred to the sample-receiving custodian at the laboratory. 9.9 SAMPLING EQUIPMENT The following are examples of sampling equipment used by the City: • Sampling pole with fixed container • Sampling pole with removable container • Sampling pail and rope • Stream velocity meter • Grab-n-Go Sample Kit 9.10 GRAB-N-GO SAMPLING KIT The City maintains a Grab-n-Go sampling kit located at the Collections Building. The kit is inspected quarterly by the Collection Systems Supervisor. Additionally, any City employee utilizing the kit is responsible for decontami-nating sampling equipment and field monitoring devices and replenishing the kit. Spill Sample Collection Kit Inventory: • Cooler • Surface Water Sampling SOP (in Sewer Spill/Backup Response Workbook) • Ice Pack • 5 Ammonia sample bottles • 15 Bacti sample bottles City of Antioch Spill Emergency Response Plan Draft 5-25-23 © 2004-2023 DKF Solutions Group, LLC. All rights reserved. Page 23 of 48 • Minimum of 20 blank sample bottle labels • Digital camera or smart phone camera • Latex gloves • Safety glasses/goggles • Waterproof Pen • Surface Water Sampling Worksheet (in Sewer Spill/Backup Response Workbook) • Chain of Custody form (in Sewer Spill/Backup Response Workbook) 9.11 DECONTAMINATION PROCEDURES Removing or neutralizing contaminants from sampling equipment minimizes the likelihood of sample cross contamination, reduces or eliminates transfer of contaminants to clean areas, and prevents the mixing of incompatible substances. Gross contamination can be removed by physical decontamination procedures. These abrasive and non-abra-sive methods include the use of brushes, air and wet blasting, and high- and low-pressure water cleaning. The decontamination procedures for the sample types and sampling equipment (other than sample bottles, which are provided to Collections Crew in a “ready to be used” condition by the lab) used at the City may be summarized as follows: 1. Physical removal 2. Tap water rinse 3. Air dry 9.12 SAMPLING PROCEDURES 9.12.1 Sample Location and Identification Procedures Samples will be collected by the Collections Crew. It is impossible to establish hard and fast rules concern-ing sampling locations. However, the following general guidelines should be applied whenever surface waters are sampled: • The sampling location should be far enough upstream or downstream of confluences or point sources so that the surface water and spill volume is well mixed. Natural turbulence can be used to provide a good mixture. • Samples should be collected at a location where the velocity is sufficient to prevent deposition of solids, and to the extent practical, should be in straight reach having uniform flow. All flow in the reach should be represented, so divided flow areas should be avoided, and samples should be taken towards the middle of the reach where feasible. • Sampler must always stand downstream of the collection vessel, and sample “into the current.” Care must be taken to avoid introducing re-suspended sediment into the sample. 9.12.2 Surface Water Sampling Standard Operating Procedure (SOP) The Surface Water Sampling SOP, Section F in the Sewer Spill/Backup Response Workbook, provides step-by-step procedures to collect samples and deliver them for analysis in accordance with State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR), Element 6.
City of Antioch Spill Emergency Response Plan Draft 5-25-23 © 2004-2023 DKF Solutions Group, LLC. All rights reserved. Page 24 of 48
9.12.3 Follow Up Sampling Sampling will be repeated every 24 hours, or as directed by the RWQCB or the Contra Costa County Envi-ronmental Health, until such time as one of the following criteria have been met: • The Contra Costa County Environmental Health or the RWQCB indicates follow up sampling is no longer required, or • Both the ammonia and bacteria levels downstream are approximately equal to or less than the upstream levels. 9.13 SAFETY AND ACCESS EXCEPTIONS If the City encounters access restrictions or unsafe conditions that prevents its compliance with spill response requirements or monitoring requirements in State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR), the City shall provide documentation of access restrictions and/or safety hazards in the corresponding required report. Personal safety of staff engaged in any fieldwork activity (e.g. in transit, walking or hiking, and any field activities while at the sample site) is of primary importance. Staff should never place themselves in dangerous or risky situations. Any hazards that are known by field personnel should be communicated to other members of the field crew. Fieldwork should be postponed if there is indication that engagement in the field activity could cause bodily harm. Working during lightning storms, in heavy vegetation or poison oak, near aggressive wildlife or domestic animals, traversing steep or rugged terrain, unstable slopes or creek banks, near swiftly moving water or potential flash flood conditions, or during snowy weather is not considered "normal risk." If any member of the field crew is uncomfortable with a reasonable self-determined hazardous field condition, it is that person’s responsibility to bring this to the attention of the onsite field supervisor or their supervisor. A “reasonable self-determined haz-ardous field condition” is defined as other than normal risk. Supervisors shall not dismiss any person’s spoken concerns that field conditions are too hazardous to complete the work assignment. The person taking the samples must have adequate protection, including protective clothing. They must wear gloves, as protection against chemical and/or bacteriological hazards, while they are sampling or handling samples that are known or suspected to be hazardous (e.g. visible solids or sheens, downstream from sewage spills, etc.), or if hands have open wounds. The type of gloves worn shall be determined by the sampling circumstance and type of pollutants expected – for instance longer gloves are needed when samples must be taken well below the surface. When in a boat or wading in a stream and where the danger of drowning exists, a personal floatation device shall be worn at all times in addition to following the other requirements of Title 8 CCR 1602 Working Over or Near Water. Other protective measures shall be taken in accordance with City safety procedures. Upon arrival at a sampling site, safety equipment such as signs, cones, lights, etc. shall be set out as appropriate. Vehicles shall be parked in locations and directions to minimize traffic disruption and avoid sample contamination. Photos should be ultimately taken of the placement of all safety equipment and signage. The following guidelines apply to all fieldwork by City staff. • No sample or measurement is worth the risk of injury.
City of Antioch Spill Emergency Response Plan Draft 5-25-23 © 2004-2023 DKF Solutions Group, LLC. All rights reserved. Page 25 of 48 • All staff shall use proper personnel protective gear as appropriate for the incident (e.g., life preservers, gloves, goggles, etc.) • Field sampling crews should consist of at least two members unless otherwise approved by a supervisor. • Be conscious of the whereabouts of rattlesnakes, mountain lions, and other dangerous animals. • Open body wounds are entry sites for infection; take the necessary precautions for self-protection. • If there is storm activity in the work area, wait for safer conditions to develop or postpone the sampling. • Do not sample at night without approval from your supervisor. • Do not trespass on private property or posted restricted public lands without prior permission and written approval from property owner or administrator. • If strange or suspicious looking people are in the work area, either wait for them to leave or postpone the work to a later time. Do not force confrontations with strangers and back away from any confron-tations with the public. Be courteous and understanding of public concerns of the situation. • Take the necessary precautions against exposure to harmful weather conditions such as heat, wind, snow, cold, rain, etc. • Carefully evaluate a given on-site situation to determine if the task can be performed safely. • Streams will not be entered unless the responding employees have the necessary protective footwear (e.g. rubber boots, waders) and the footwear does not pose an additional risk to worker safety (e.g. wad-ers filling with water if the employee slips in the stream). • Streams will not be entered if deemed unsafe to so by the most senior employee on the responding crew and if entered, will only be done so in accordance with Title 8 CCR Section 1602 Work Over or Near Water. 9.14 SPILL TECHNICAL REPORT: Spill Technical Report for Individual Category 1 Spill in which 50,000 Gallons or Greater Discharged into a Surface Water For any spill in which 50,000 gallons or greater discharged into a surface water, within 45 calendar days of the spill end date, the Collection Systems Superintendent shall submit a Spill Technical Report to the online CIWQS Sanitary Sewer System Database.

State Water Board Order No. WQ 2022-0103-DWQ (SSSWDR), Element 6, ATTACHMENT D, Page D-6) Every spill event is an opportunity to evaluate the City adherence to response and reporting procedures and effectiveness of the response. Each spill event is unique, with its own elements and challenges including volume, cause, location, ter-rain, climate, and other parameters. As soon as possible after spill events all the participants, from the person who received the call to the last person to leave the site, will meet to review the procedures used and to discuss what worked and where improvements could be made in responding to and mitigating future spill events. The results of the debriefing will be documented and tracked to ensure the action items are completed as scheduled.

11.1 FAILURE ANALYSIS INVESTIGATION The objective of the failure analysis investigation is to determine the “root cause” of the spill and to identify corrective action(s) needed that will reduce or eliminate future potential for the spill to recur or for other spills to occur. The investigation will include reviewing all relevant data to determine appropriate corrective action(s) for the line segment. The investigation may include: • Reviewing and completing the Sanitary Sewer Spill Report and any other documents related to the inci-dent • Reviewing the incident timeline and other documentation regarding the incident • Reviewing communications with the reporting party and witness • Reviewing volume estimate, volume recovered estimate, volume estimation assumptions and associated drawings • Reviewing available photographs • Interviewing staff that responded to the spill • Reviewing past maintenance records • Reviewing past CCTV records, • Conducting a CCTV inspection to determine the condition of all line segments immediately following the spill and reviewing the video and logs, • Reviewing any Fats, Oils, Roots and Grease (FROG) related information or results • Post spill debrief records • Interviews with the public at the spill location The product of the failure analysis investigation will be the determination of the root cause and the identification and scheduling of the corrective actions. The Collection System Failure Analysis Form (in Sanitary Sewer Spill/Backup Response Workbook) will be used to document the investigation. 12. SPILL RESPONSE TRAINING (ref.

DRAINAGE CONVEYANCE SYSTEM: A drainage conveyance system is a publicly- or privately-owned separate storm sewer system, including but not limited to drainage canals, channels, pipelines, pump stations, detention basins, infiltration basins/facilities, or other facilities constructed to transport stormwater and non-stormwater flows. SPILL: 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. Exfiltration of sewage is not considered to be a spill under SSWDR if the exfiltrated sewage remains in the subsurface and does not reach a surface water of the State. • Category 1 Spill: A Category 1 spill is a spill of any volume of sewage from or caused by a sanitary sewer system regulated under SSWDR that results in a discharge to: o A surface water, including a surface water body that contains no flow or volume of water; or o A drainage conveyance system that discharges to surface waters when the sewage is not fully captured and returned to the sanitary sewer system or disposed of properly. Any spill volume not recovered from a drainage conveyance system is considered a discharge to surface water, unless the drainage conveyance system discharges to a dedicated stormwater infiltration basin or facility. A spill from an City-owned and/or operated lateral that discharges to a surface water is a Category 1 spill; the City shall report all Category 1 spills per section 3.1 of Attachment E1 (Notification, Monitoring, Reporting and Recordkeeping Requirements) of SSWDR. • Category 2 Spill A Category 2 spill is a spill of 1,000 gallons or greater, from or caused by a sanitary sewer system regulated under SSWDR that does not discharge to a surface water. A spill of 1,000 gallons or greater that spills out of a lateral and is caused by a failure or blockage in the sanitary sewer system, is a Category 2 spill. • Category 3 Spill A Category 3 spill is a spill of equal to or greater than 50 gallons and less than 1,000 gallons, from or caused by a sanitary sewer system regulated under SSWDR that does not discharge to a surface water. A spill of equal to or greater than 50 gallons and less than 1,000 gallons, that spills out of a lateral and is caused by a failure or blockage in the sanitary sewer system is a Category 3 spill. • Category 4 Spill A Category 4 spill is a spill of less than 50 gallons, from or caused by a sanitary sewer system regulated under SSWDR that does not discharge to a surface water. A spill of less than 50 gallons that spills out of a lateral and is caused by a failure or blockage in the sanitary sewer system is a Category 4 spill. WATERS OF THE STATE: Waters of the State are surface waters or groundwater within boundaries of the state as defined in Water Code section 13050(e), in which the State and Regional Water Boards have authority to protect beneficial uses. Waters of the State include, but are not limited to, groundwater aquifers, surface waters, saline waters, natural washes and pools, wetlands, sloughs, and estuaries, regardless of flow or whether water exists during dry conditions. Waters of the State include waters of the United States. © 2004-2023 DKF Solutions Group, LLC. All rights reserved.

City of Antioch Spill Emergency Response Plan Spill/Backup Response Flowchart C-1: Page 2 BEGIN DIVERSION AND CONTAINMENT, AS NECESSARY1.DIVERT AWAY FROM SENSITIVE AREAS: a. Cover unplugged storm drains w/mats, or use dirt/other material to divert sewage away from sensitive areas (e.g., schools, playgrounds, intersections, etc.)b. ENSURE PUBLIC CONTACT DOES NOT OCCUR. Use cones/barricades to isolate area.2. CONTAIN SPILL & RETURN TO SYSTEM, IF POSSIBLE:a.As practical, plug or block drainage conveyance system entry locations or use rubber mats to cover basin inlet and divert flow to a downstream sanitary sewer manhole (barricade manhole if left open and monitor after barricade) or area suitable to capture the spill for later collection.If any amount has already reached the drainage conveyance system, trace it downstream to a dry manhole and block it from entering surface waters. i.e., plugs, sandbags, or vacuum truck.b.If you are confident that you can capture the spill in the drainage conveyance system, trace it downstream to a dry manhole and then divert the spill to the drainage conveyance system for later recovery and return to the sanitary sewer.c.Use bypass pumps to pump around blockage until it can be removed.d.Divert to low area of ground where it can be collected later.3.PHOTOGRAPH each drainage conveyance system entry location.
ADDRESS CAUSE OF SPILL/BACKUP ASAP1.For spill/backups not related to a pump station, relieve the stoppage. Note the distance of the obstruction from the manhole and catch/remove debris that could cause another stoppage. After flow has returned to normal, clean the pipe thoroughly. Consider televising (CCTV) the affected line.2.For pump station related spill/backups refer to that station’s Emergency Response Plan.3.Photograph staff activities while clearing the blockage.

Example 1: 27" ÷ 12 = 2.25' Example 2: 1¾" = ?' 1" (0.08') + ¾" (0.06') = 0.14' Volume of one cubic foot 7.48 gallons of liquid Area: Two-dimensional measurement represented in square feet (SQ/FT or ft2) Square/rectangle: Area = Length x Width Circle: Area = π x r2 (where π ≈ 3.14 and r = radius = ½ diameter) Triangle: Area = ½ (Base x Height) Volume: Three-dimensional measurement represented in cubic feet (CU/FT or ft3) Rectangle/square footprint: Volume = Length x Width x Depth Circle footprint (cylinder): Volume = π x r2 x Depth (where π ≈ 3.14 and r = radius = ½ diameter) Triangle footprint: Volume = ½ (Base x Height) x Depth Depth: Wet Stain on Concrete or asphalt surface If the depth is not measurable because it is only a wet stain, use the following estimated depths: o Depth of a wet stain on concrete surface: 0.0026' (1/32") o Depth of a wet stain on asphalt surface: 0.0013' (1/64") These were determined to be a reasonable depth to use on the respective surfaces through a process of trial and error. One gallon of water was poured onto both asphalt and concrete surfaces. Once the area was determined as accurately as possible, different depths were used to determine the volume of the wetted footprint until the formula produced a result that (closely) matched the one gallon spilled. This process was repeated several times. Depth: Contained or “Ponded” sewage Measure actual depth of standing sewage whenever possible. When depth varies, measure several representative sample points and determine the average. Use that number in your formula to determine volume.

STEP 1: Position yourself so that you have a vantage point where you can see the entire spill. STEP 2: Imagine one or more buckets or barrels of water tipped over. Depending on the size of the spill, select a bucket or barrel size as a frame of reference. It may be necessary to use more than one bucket/barrel size. STEP 3: Estimate how many of each size bucket or barrel it would take to make an equivalent spill. Enter those numbers in Column A of the row in the table below that corresponds to the bucket/barrel sizes you are using as a frame of reference. STEP 4: Multiply the number in Column A by the multiplier in Column B. Enter the result in Column C. A B C Size of bucket(s)/barrel(s) How many of this size?

Licensed to City of Antioch for City use only. 5-25-23 City of Antioch Spill Emergency Response Plan Customer Information Letter (Backup Only) F-5 (English) Dear Property Owner: We recognize that sewer backup incidents can be stressful and require immediate response while all facts concerning how an incident occurred are still unknown. Rest assured that we do all we can to prevent this type of event from occurring in the first place. Nevertheless, occasionally tree roots or other debris in the sewer lines causes a backup into homes immediately upstream of the blockage. At this time the City is investigating the cause of this incident. If the City is found to be responsible for the incident, we are committed to cleaning and restoring your property, and to protecting the health of those affected during the remediation process. The cleaning contractor provided by the City has been selected because of their adherence to established protocols that are designed to assure to all parties thorough, cost-effective and expeditious cleaning services. You also have the right to select your own cleaning contractor, but the City does not guarantee payment of fees/expenses incurred and reserves the right to dispute fees/expenses deemed not usual and customary. Depending on the extent of the backup our Collections Crew may advise you to consider relocating temporarily while the living area is cleaned. In that case, the City will arrange for lodging for you for one night. Please see the Lodging Authorization form for details. To discuss this matter, contact the Collection Systems Superintendent at (925) 779-6962. To submit a claim for damages contact the City Attorney’s Office at (925) 779-7015. Sincerely, The City of Antioch

Licensed to City of Antioch for City use only. 5-25-23 City of Antioch Spill Emergency Response Plan Your Responsibilities as a Private Property Owner (Backup Only) F-6: Page 1 How a Sewer System Works A property owner's sewer pipes are called service laterals and are connected to larger local main and regional trunk lines. Service laterals run from the connection at the home to the connection with the public sewer. Depending on your location, a portion of the lateral is the responsibility of the property owner and must be maintained by the property owner. How do sewage spills happen? Sewage spills occur when the wastewater in underground pipes spills through a manhole, cleanout, or broken pipe. Most spills are relatively small and can be stopped and cleaned up quickly, but left unattended they can cause health hazards, damage to homes and businesses, and threaten the environment, local waterways, and beaches. Common causes of sewage spills include grease build-up, tree roots, broken/cracked pipes, missing or broken cleanout caps, undersized sewers, and groundwater/rainwater entering the sewer system through pipe defects and illegal connections. Prevent most sewage backups with a Backflow Prevention Device This type of device can help prevent sewage backups into homes and businesses. If you don’t already have a Backflow Prevention Device, contact a professional plumber or contractor to install one as soon as possible. Is my home required to have a backflow prevention device? Section 710.1 of the Uniform Plumbing Code (U.P.C.) states: “Drainage piping serving fixtures which have flood level rims located below the elevation of the next upstream manhole cover or private sewer serving such drainage piping shall be protected from backflow of sewage by installing an approved type of backwater valve.” The intent of Section 710.1 is to protect the building interior from mainline sewer spills or surcharges. Additionally, U.P.C. 710.6 states: “Backwater valves shall be located where they will be accessible for inspection and repair at all times and, unless continuously exposed, shall be enclosed in a masonry pit fitted with an adequately sized removable cover.”

Sometimes, homeowner’s insurance will pay for the necessary cleaning due to sewer backups. Not all policies have this coverage, so check with your agent. If you decide to clean up a small spill inside your home, protect yourself from contamination by observing the following safety measures. Those persons whose resistance to infection is compromised should not attempt this type of clean up. Other Tips: • Keep children and pets out of the affected area. • Turn off heating/air conditioning systems • Wear rubber boots, rubber gloves, and goggles during cleanup. • Discard items that cannot be washed and disinfected (such as: mattresses, rugs, cosmetics, toys, etc.) • Remove and discard drywall and insulation that has been contaminated with sewage or flood waters. • Thoroughly clean all hard surfaces (such as flooring, concrete, molding, wood and metal furniture, countertops, appliances, sinks and other plumbing fixtures) with hot water and laundry or dish detergent. • Help the drying process with fans, air conditioning units, and dehumidifiers. • After completing cleanup, wash your hands with soap and water. Use water that has been boiled for 1 minute (allow the water to cool before washing your hands) OR use water that has been disinfected (solution of 1/8 teaspoon of household bleach per 1 gallon of water). Let it stand for 30 min. If water is cloudy, use ¼ teaspoon of household bleach per 1 gallon of water. • Wash clothes worn during cleanup in hot water & detergent (wash apart from uncontaminated clothes). • Wash clothes contaminated with sewage in hot water and detergent. Consider using a Laundromat until your onsite wastewater system has been professionally inspected and serviced. Spill cleanup outside the home: • Keep children and pets out of the affected area until cleanup has been completed. • Wear rubber boots, rubber gloves, and goggles during cleanup of affected area. • Clean up sewage solids (fecal material) and place in properly functioning toilet or double bag and place in garbage container. • On hard surfaces areas such as asphalt or concrete, it is safe to use a 2% bleach solution, or ½ cup of bleach to 5 gallons of water, but don’t allow it to reach a storm drain as the bleach can harm the environment. • After cleanup, wash hands with soap and water. Use water that has been boiled for 1 minute (allow to cool before washing your hands) OR use water that has been disinfected (solution of 1/8 teaspoon of household bleach per 1 gallon of water). Let it stand for 30 min. If water is cloudy, use ¼ teaspoon of household bleach per 1 gallon of water. • Wash clothes worn during cleanup in hot water and detergent (wash apart from uncontaminated clothes). • Wash clothes contaminated with sewage in hot water and detergent. Consider using a laundromat until your onsite wastewater system has been professionally inspected and serviced.
Seek immediate attention if you become injured or ill during or after the cleanup process.

Los servicios laterales se ejecutan desde la conexión en el hogar hasta la conexión con el sistema de alcantarillado del Distrito. Estos laterales son responsabilidad del propietario y deben ser mantenidos por el propietario. ¿Cómo ocurren los derrames de aguas residuales? Los derrames de aguas residuales ocurren cuando las aguas residuales en las tuberías subterráneas se desbordan a través de un pozo de acceso, limpieza o tubería rota. La mayoría de los derrames son relativamente pequeños y se pueden detener y limpiar rápidamente, pero si se los deja desatendidos, pueden causar riesgos para la salud, dañar viviendas y negocios y amenazar el medio ambiente, las vías fluviales locales y las playas. Las causas comunes de derrames de aguas residuales incluyen acumulación de grasa, raíces de árboles, tuberías rotas / agrietadas, tapas de limpieza faltantes o rotas, alcantarillas de tamaño insuficiente y aguas subterráneas / pluviales que ingresan al sistema de alcantarillado a través de defectos en las tuberías y conexiones ilegales. Prevenga la mayoría de las copias de seguridad de aguas residuales con un dispositivo de prevención de reflujo Este tipo de dispositivo puede ayudar a prevenir las copias de seguridad de aguas residuales en hogares y empresas. Si aún no tiene un dispositivo de prevención de reflujo, comuníquese con un plomero o contratista profesional para instalar uno lo antes posible. ¿Se requiere que mi hogar tenga un dispositivo de prevención de reflujo? La Sección 710.1 del Código Uniforme de Plomería (UPC) establece: “Los accesorios de tuberías de drenaje que tienen llantas de nivel de inundación ubicadas debajo de la elevación de la siguiente boca de alcantarilla corriente arriba o la alcantarilla privada que atiende dicha tubería de drenaje deben protegerse contra el reflujo de aguas residuales al instalar un tipo de válvula de evacuación ”. La intención de la Sección 710.1 es proteger el interior del edificio de los desagües o sobrecargas de alcantarillado de la línea principal. Adicionalmente, U.P.C. 710.6 dice: Las válvulas de aguas residuales deben ubicarse donde puedan ser inspeccionadas y reparadas en todo momento y, a menos que estén continuamente expuestas, deben estar encerradas en un pozo de mampostería equipado con una cubierta removible del tamaño adecuado.

Licensed to City of Antioch for City use only. 5-25-23 City of Antioch Spill Emergency Response Plan Surface Water Sampling SOP: Introduction & Overview G-3: Page 2 Before beginning the sampling process there are several important steps that must be taken to ensure that the samples collected are representative of the water quality in the area being monitored. These steps include: 1. Gathering the necessary equipment: • The surface water sampling worksheet, chain of custody, sampling pole, sample containers, and PPE are essential tools that must be prepared and organized before sampling can begin. 2. Donning appropriate personal protective equipment: • To protect against exposure to potentially harmful contaminants and the sulfuric acid preservative in the Ammonia sample bottles, workers must wear gloves, eye protection, and other personal protective equipment, as needed. 3. Determining the point of spill entry into the waterway: • It's important to locate the point at which any spill entered the waterway in order to collect the required samples: point of entry into the surface water, downstream, and upstream.
The approximate stream velocity and time since the spill flow to the surface water stopped should be determined to calculate the appropriate distance to move downstream to collect: 1. The downstream sample, 2. Move upstream to collect the spill entry point sample, 3. And move further upstream to collect the upstream or reference sample.

Coli 1 bacti bottle 1 bacti bottle 1 bacti bottle 1 bacti bottle Water samples must be collected in different bottles for various tests and then transported in a cooler with ice packs. For each of the three sampling sites (plus drainage conveyance system as applicable), one bottle is needed for ammonia/nitrogen testing, and one bacti bottle is required for each type of bacteria being tested. Additionally, one field blank sample is required for each constituent. Field blank sample bottles are filled with sterilized water during sampling to serve as quality control on the sampler's sampling methods. Since the sample bottles contain sterilized water, bacteria and ammonia should not be present in the water. If the lab analysis shows the presence of bacteria or ammonia, it indicates that the sampler's method may not have been correct, and the other bacti samples may have been contaminated. Surface Water Sampling – Preparation
Step 1 of 4 Prepare the cooler for sample storage by adding an instant ice pack, ice pack, or ice to keep the samples cold during transport to the lab.

Step 3 of 4 Begin completing the Surface Water Sampling Worksheet to record the relevant information about the sampling location and collected samples.
Step 4 of 4 To determine which direction is upstream and downstream for sample collection, you should observe the direction of water movement from the point of discharge.

Licensed to City of Antioch for City use only. 5-25-23 City of Antioch Spill Emergency Response Plan Surface Water Sampling SOP: Surface Water Sampling G-6: Page 1 The purpose of this procedure is to provide a standard for collecting surface water samples to assess water quality, avoid contamination, and ensure that samples can be accurately labeled and transported to the lab for processing. Notes: Start by collecting downstream samples first. In order to determine where the downstream sample is located in a stream, creek, or river, you will need to determine the velocity of the surface water. This can be accomplished through the use of a stream velocity meter or by measuring off a distance along the bank and timing how long it takes for a floating object to travel that distance. Use the formula on the Surface Water Sampling Worksheet to calculate the stream velocity. Once known, determine the time that the spill has not been entering the surface water. This, along with the stream velocity, will inform you how far downstream you need to travel to collect the downstream sample.

This should include latex or rubber gloves and safety glasses.
Step 2 of 9 Label all samples with their location (refer to table on G-8), your name, and the date and time they are collected. Record this information on the surface water sampling worksheet.
Step 3 of 9 Take photos of each sample location and ensure a reference point is visible in each photo. In the photo (left), the dock and sign serve as excellent reference points.

To reduce the likelihood of contamination, remove the cap immediately before collecting each sample.
Step 5 of 9 To prevent sample contamination, do not allow the inside of the cap to touch anything while you are obtaining the sample.
Step 6 of 9 When filling the ammonia nitrogen sample bottle, don't overfill it because it contains sulfuric acid. Sweep the bottle or dipper upstream and out of the water without disturbing the bottom sediment. Remember to leave the sulfuric acid in the bottle and avoid skin contact.

If there is no clear fill line, fill it to the “neck” of the bottle.
Step 8 of 9 Open the Bacteria sample container and allow water to gently flow into the bottle just to the fill line.
Repeat the sampling process for all sample points, and provide a “field blank” sample using sterile water, which verifies the quality of the samples. Step 9 of 9 Place all samples in the cooler on the ice pack. To ensure accurate analysis, the Bacti samples must be transported to the lab within 6 hours of the time of collection.
