From:George N. Harris II, Senior Director/Treasurer – Admin Services Subject:Approval of Nutanix annual licensing, maintenance, and support.

G.C. Section 84308: No
Fiscal Impact:
$156,769.42 as per the attached quote to be paid from account 112118000.5361.

Background:

The City of Lancaster utilizes Nutanix Hyperconverged Infrastructure (HCI) for our server and data storage needs. Nutanix HCI is a combination of servers and storage built into a distributed infrastructure platform with intelligent software to create flexible building blocks that replace legacy infrastructure consisting of separate servers, storage networks, and storage arrays. This eliminates common pain points associated with legacy infrastructure and allows for greater flexibility in computing resources as well as exceptional efficiency. Nutanix HCI has been employed with the City since 2017 and City IT staff want to continue the relationship with Nutanix for the foreseeable future. The proposed support and licensing agreement provides the City with hardware and software support to ensure the City’s data center hardware and applications are available and operational with limited interruptions.

The quote was sourced from SHI utilizing the Sourcewell – Technology Products and Solutions competitively bid contract number 121923-SHI.

Background:

In July 2020, the City Council adopted a resolution authorizing the submission of an initial application and required 5-Year Plan (Plan) for California Department of Housing and Community Development (HCD) PLHA program funds. In May 2021, following submission and approval of the City’s initial Plan, agreements to allow access to first-year 2019 funds in the amount of $694,855 were executed. Shortly thereafter, the City submitted a streamlined HCD PLHA application for its 2020 allocation of $1,080,020 on June 11, 2021.

On August 17, 2022, HCD released a NOFA for 2021 PLHA funds advising of an intended City of Lancaster allocation of $1,188,528. In response staff prepared the required application and an accompanying amended Plan to allow for utilization of the funds in alignment with the City Council’s goals and previously approved commitments. On January 10, 2023, the City Council authorized staff to apply for the 2021 funds and approved the amended Plan reallocating the percentages of funds among selected eligible activities for year two (2020) and three (2021). 1 9
9 7
The PLHA Plan reflects varying annual percentage allocation of PLHA funds to three (3) eligible activities:

1. To make a construction loan for a 113-unit multifamily rental housing development currently owned by the Housing Authority, as well as predevelopment and/or construction loans for 1-2 additional multifamily rental developments; and

2. To make deferred loans for pre-development costs and non-recurring closing costs to assist low-and moderate- income owner occupied households with incomes of no more than 120% AMI to construct an Accessory Dwelling Unit (ADU) on their property; and

3. To provide down payment assistance loans to low- and moderate-income workforce households to purchase their first home.

On June 25, 2024, the City Council authorized staff to apply for the 2022 PLHA funds.

This report seeks City Council consideration regarding the approval of an amendment to Resolution 24-32, requesting the removal of Jason Caudle’s name to replace it with “City Manager.” No additional modifications are required.

Date:April 8, 2025
To: Mayor Parris and City Council Members
From:Jenn Seguin, Manager
Trolis Niebla, City Manager
Subject:Adoption of the 2025 Local Hazard Mitigation Plan (LHMP) Recommendations:

Adopt Resolution No. approving the 2025 Local Hazard Mitigation Plan (LHMP) for final FEMA approval. By adopting the LHMP, the City will maintain compliance with Federal Emergency Management Agency (FEMA) requirements, ensuring continued eligibility for federal hazard mitigation and disaster relief funding; establish a foundation for future action to incorporate the LHMP into the Safety Element; strengthen hazard mitigation planning to reduce disaster risks in the community.

G.C. Section 84308: No
Fiscal Impact:

There is no immediate fiscal impact associated with the adoption of the LHMP. However, maintaining an adopted and FEMA-approved LHMP ensures continued eligibility for federal and state funding for hazard mitigation projects and disaster recovery assistance.

Background:

The Federal Disaster Mitigation Act of 2000 requires state and local governments to develop and maintain a Local Hazard Mitigation Plan (LHMP) to qualify for certain types of federal disaster assistance. The LHMP identifies risks, vulnerabilities, and mitigation actions to reduce the impact of disasters on the community. The City has completed an update to its LHMP, which has been reviewed and approved by the Federal Emergency Management Agency (FEMA) as "approvable pending adoption." Formal adoption by the City Council is required for FEMA’s final approval.

A future action will be required to formally adopt the LHMP into the Safety Element of the General Plan for compliance with Assembly Bill 2140 (AB 2140). This step will enhance eligibility for additional state cost-share funding for Public Assistance projects under the California Disaster 2 0
0 3
Assistance Act (CDAA) in future disasters. The (LHMP) outlines specific mitigation actions that align with the City’s emergency preparedness and resilience goals.

To: Mayor Parris and City Council Members
From: Marissa Diaz, Director - Public Works
Bruce Katz, Assistant Director – PW Utility Services
Subject: Approval of Sewer System Management Plan Update Recommendation:

Approve the Sewer System Management Plan Update, and authorize the Director of Public Works, or her designee, to certify via the State established electronic reporting system known as California Integrated Water Quality System (CIWQS).

G.C. Section 84308: No
Fiscal Impact:

None.

Background:

On May 2, 2006, the State Water Resources Control Board (SWRCB) adopted General Order No. 2006-0003-DWQ (2006 Order), which established General Waste Discharge Requirements (WDRs) for all publicly owned or operated sanitary sewer systems within the State of California.

The WDRs require that owners and operators of sewer collection systems report sewer spills in the California Integrated Water Quality System (CIWQS), an electronic reporting system developed by the SWRCB, and develop and implement a Sewer System Management Plan (SSMP) with the goal of reducing sewer spills. The SSMP is a written document that details how a specific sewer collection system is operated, maintained, repaired, and funded. The City of Lancaster’s original SSMP was completed and approved by the City Council in April 2009.

On December 6, 2022, Order WQ 2022-0103-DWQ (2022 Order) was adopted by the State Water Resources Control Board. According to the 2022 Order, the SSMP must be updated and approved by the governing body every six (6) years. Once approved, the SSMP will be uploaded and certified via the electronic reporting system on CIWQS.

The SSMP Update includes the following:
2 0

1. Updated Operations and Maintenance practices

2. Updated Contact Information for City staff

3. New Spill Emergency Response Plan (SERP) in place of Overflow Emergency Response Plan (OERP)

Introduction

On December 6, 2022, SWRCB adopted Order No. WQ 2022 -0103-DWQ, which serves as the statewide waste discharge requirements and supersedes the previous State Water Resources Control Board (Order WQ 2022-0103-DWQ) and amendments thereafter.

Through this General Order, the State Water Board requires an Enrollee to:
• Comply with federal and state prohibitions of discharge of sewage to waters of the State, including federal waters of the United States;
• Comply with specifications, and notification, monitoring, reporting and recordkeeping requirements in this General Order that implement the federal Clean Water Act, the California Water Code (Water Code), water quality control plans (including Regional Water Board Basin Plans) and policies;
• Proactively operate and maintain resilient sanitary sewer systems to prevent spills; • Eliminate discharges of sewage to waters of the State through effective implementation of a Sewer System Management Plan;
• Monitor, track, and analyze spills for ongoing system -specific performance improvements; and • Report noncompliance with this General Order per reporting requirements.

This SSMP , developed by the City of Lanca ster (City), is organized into 11 chapters to parallel the requirements included in the GWDRs. Each section or subsection of each chapter addresses the individual elements of the SSMP.

Per the California State Water Resources Control Board, the Enrollee shall conduct an internal audit of its Sewer System Management Plan, and implementation of its plan, at a minimum frequency of once every three years.

SSMPs must be self-audited at least once every three (3) years and updated every six (6) years after the date of its last Plan Update due date.

2.3 Organizational Charts and Contact Information

2.3.1 City Organization

The City incorporated in November 1977, as a general law city. Currently, the City is a charter city under the laws of the State of California. The City operates under a City Council-City Manager form of government. The County of Los Angeles CSMD provided sewer O&M for the City until July 1, 2008, at which time the City's Utility Services Division (USD) of the Public Works Department assumed all maintenance responsibilities. The organization chart for the USD is provided below followed with a brief description of the duties of each key position.

In 2014 , the City reorganized the Public Works Department. The Public Works Department was renamed to the Development Services Department; the Maintenance Services Division and the Utility Services Divisions were merged into Utilities/Maintenance Services Division, which was referred to as the Public Works Division.

In April 2019, the Public Works Division was reorganized, and the Utility Services Section was removed from the Public Works Division, and became its own separate division, now known as the Utility Services Division.

In May 2023, the Development Services Department was reorganized and renamed the Public Works Department .

e) Enforce any violation of its sewer ordinances, service agreements, or other legally binding procedures; and,

f) Obtain easement accessibility agreements for locations requiring sewer system operations and maintenance, as applicable.

3.1 City Municipal Code

The legal authorities for the City to comply with the SSMP requirements are contained within Municipal Code Title 13 (Public Services), Chapters 13.07 (Sanitary Sewers), 13.08 (Sanitary Sewers and Industrial Waste) and 13.09 (Sewer Service Charges), and Title 15 (Building and Construction) Chapter

15.20 (Plumbing Code), which adopts by reference the 2021 California Plumbing Code.

3.2.1 Prevention of Illicit Discharges

Measures to prohibit illicit discharges are currently included in the City's Municipal Code Title 13.07.010, and Title 13.08, which refers the reader to the 202 1 California Plumbing Code dealing with these provisions in Chapter 3 sections 303, 305, 306; Chapter 7 section 714 and Chapter 11 section 1101. The specific purpose of the section is to prevent the discharge of any pollutant or any combination of pollutants into the sewers that would obstruct or damage the sanitary sewer system, interfere with treatment, or threaten harm to human health or the environment. Additionally, Section 714 (Damage to Public Sewer or Private Sewage System) prohibits the opening or entering of any appurtenance and prohibits the discharge of any cesspool effluent directly into a manhole or other opening in the City's collection system, except pursuant to special permission issued by the City for such discharge.

Examples of discharges that are covered under the current City legal authorities are discussed below:

a) Stormwater - Municipal Code Section 13.08.730 (Deposit of Certain 21 | Page
Substances Prohibited) specifically prohibits the discharge of stormwater into a City sewer. The California Plumbing Code specifically limits the discharge of stormwater in Chapter 11, Section 1101. 3 (Storm Water Drainage to Sanitary Sewer Prohibited).

b) Industrial Waste - The legal authority for these wastes is contained in Chapter 13.08 Section 500 et seq. The City has also adopted by reference the California Plumbing Code , which also prohibits these types of discharges in Chapter 3, Section 306 (Damage to Drainage Systems or Public Sewer).

c) FOG- Title 13.08.730 of City's Municipal Code (Deposit of Certain Substances Prohibited) specifically prohibits the discharge of FOG materials into a City sewer. The City Council also has adopted the FOG - related Ordinance No. 1066 that will deal directly with this issue. The City has also implemented public outreach efforts to educate and train residential households and FSEs on the problems related to FOG in the sewer system. In addition, the City has also adopted by reference the California Plumbing Code, which deals specifically with this issue in Chapter 10, Sections 1009, 1014 and 1015.

d) I/I- Section 306.2 of the California Plumbing Code prohibits the discharge of extraneous waters to a sanitary drainage system. City Municipal Code Chapter 13.07, Section 200, specifically limits the disposal of I/ I. Section

13.07.060 requires the house lateral to be maintained by the owner and provides the City with the authority to require or complete repairs when necessary to assure safe and sanitary conditions.

3.2.2 Proper Design and Construction of Sewers and Connections

The City has the responsibility for the review and approval of plans and specifications for the construction and dedication of sanitary sewers, house laterals and sewer-related appurtenances through the development processes of the Public Works Department and Community Development Department. The Division ensures all construction within the public right- of-way complies with adopted codes, ordinances, engineering standards, and the Subdivisions Map Act. All sewers and sewer related facilities are to be designed and constructed according to the "Standard Specifications of Public Works Construction" as adopted by the City Council and must be filed in the office of City Engineering and be prepared under the direct supervision of and signed by a Registered Civil Engineer of the State of California.

The authority for the design, approval, inspection and construction of all new, rehabilitated and/or replaced sewer pipelines and appurtenances, pump stations and other sewer infrastructure is granted in Chapter 13.08, Articles 1,3 and 4 of the City Munici pal Code. The City has no responsibility for the maintenance and/or replacement of house laterals.

Enforcement of all sanitary sewer provisions is granted to City staff in Municipal Code Sections 1.12.020 and 13.07.160 (Violation - Penalty). All sections provide the authority for the Director of Public Works, or his/her, designee to administer, implement and enforce any violation of the provisions of the sanitary se wer and industrial waste codes.

Chapter 4 Operation and Maintenance Program

Chapter 4 of this SSMP addresses the requirements included in Attachment D, Section 4 of the Order.

The requirements state:

a) Operation and Maintenance Program: The SSMP must include those elements listed below that are appropriate and applicable to the Enrollee's system:

b) 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 storm water conveyance facilities;

c) Describe routine preventive operation and maintenance activities by staff and contractors, including inspection and maintenance activities; a system for scheduling regular maintenance and cleaning of the sanitary sewer system, with more frequent inspections and maintenance targeted at known problem areas , including areas with tree root problems . The Preventive Maintenance Program should have a system to document scheduled and conducted activities, such as work orders;

d) Develop a rehabilitation and replacement plan to identify and prioritize system deficiencies and implement short-term and long-term rehabilitation actions to address each deficiency. The program should include regular visual and CCTV inspections of manholes and sewer pipes, and a system for ranking the condition of sewer pipes and scheduling rehabilitation.

Rehabilitation and replacement should focus on sewer pipes that are at risk of collapse or prone to more frequent blockages due to pipe defects. Finally, the rehabilitation and replacement plan should include a capital improvement plan that addresses proper management and protection of the infrastructure assets. The plan shall include a time schedule for implementing the short-term and long-term plans, plus a schedule for developing the funds needed for the capital improvement plan;

e) Provide training on a regular basis for staff in sanitary sewer system O&M, and require contractors to be appropriately trained; and

f) Provide equipment and replacement part inventories, including identification of critical replacement parts.

4.1 Collection System Mapping

The City has a GIS that it uses to create and maintain maps of its wastewater collection system facilities. The GIS was created in 2007 by conversion of CAD drawings and the City's scanned sewer record drawings and is maintained in the USD of the maintenance yard. Manholes, sewers, sewer laterals , and storm drain system components are continually added to the City's GIS through ongoing mapping maintenance efforts. Each manhole and pipe has a unique identifier. Pipe attributes stored in the GIS include pipe length, diameter, slope, material, year built, upstream and downstream manholes, and upstream and downstream invert elevations, and links to plans. Manhole attributes include year built, rim and invert elevations, and street address. In addition to being used to create sewer maps, the GIS is used as the database for other applications such as hydraulic modeling, maintenance management, video inspections, and for ad -hoc mapping and 23 | Page
database queries.

A set of map sheets is periodically generated from the GIS in pdf format suitable for viewing in Adobe Acrobat and for printing hard copy sewer map books for various uses including field maintenance activities. The map sheets are at a scale of approximately 1” = ~ 333' when printed on 11 by 17 inch pages. The maps show all parcels with addresses and street names, manholes with identifiers and special symbols for deep manholes, pipes with diameters, lengths, and flow direction arrows, and service laterals. In addition to the City's sewers, sewers owned and operated by other agencies (Sanitation District 14 of Los Angeles County, CSMD, and the City of Palmdale) are shown in different colors. Storm water conveyance facilities as included in the City's storm drain GIS are also shown on the maps, including inlets, manholes, pipes, open channels, and retention basins.

4.1.1 Updates to Existing Drawings

The field crews use electronic and hard copy maps that were produced using the GIS. Proposed corrections are identified by field crews and communicated to Utility Services staff using the Mapping/GIS Update/Correction Form shown in Appendix A. High priority corrections (those that may result in poor decision - making and potentially leading to an SSO) are entered into the GIS and updated map pages are issued as soon as possible to the field crews. Low priority corrections and new facilities are incorporated into the GIS and updated map pages are issued not less than annually.

Record drawings for LACSD trunk sewers and City sewer mains, lift stations, and appurtenant facilities are available at the Engineering counter in hard copy form.

In addition, the City scans sewer system record drawings and links the scanned images to the associated sewer facilities in the GIS. These images are also available electronically to staff through the City's Intranet.

4.1.2 New Improvement Plan Drawings

Developers are required to prepare and submit as -built drawings upon installation of new sewer mains, storm drains, and associated facilities. The City scans all of these drawings and maintains them in a document management system. On an as needed basis, the City updates the GIS to include these new facilities and then updates the pdf map set and issues revised map book pages to all map book holders.

4.2 Maintenance
The elements of the City's wastewater collection system Operation and Maintenance Program include proactive, preventive, and corrective maintenance of gravity sewers, and periodic inspection and preventive maintenance of lift station. The details of the Ci ty's operation and maintenance programs are generally described in this section.

4.2.1 Preventive Maintenance

The City cleans all sewers utilizing a grid system. The City adjusts the frequency of repeat cleanings based on the results from prior cleaning activities as delineated on the Sewer Work Order Form in Appendix B. The process is shown in the flow chart below.

The standard cleaning results are shown in Table 2, along with the criteria for changing cleaning frequencies. See Sewer Cleaning Flow Chart in Figure 3. 24 | Page

After each cycle of wastewater collection system cleaning has been completed, the City will re -evaluate the preventive maintenance approach where each asset is periodically cleaned based on the frequency appropriate to maintaining reliable operation.

Figure 3 - Sewer Cleaning Flowchart

The City's SOP for sewer cleaning is in cluded as Appendix C.

Gravity sewer maintenance is scheduled using an Excel spreadsheet. Work orders are issued to the sewer cleaning crews and the results of their work are recorded on the completed work orders which, in turn, are entered into the spreadsheet . A sample Work Order Form is included as Appendix B. Gravity sewers, where the field crew encounters problems during cleaning are scheduled for CCTV inspection and appropriate action

Excellent (no or minor defects) 0 or 1 20
Good (some defects but not deteriorating) 2 10
Fair (moderate defects) 3 7
Poor (defects deteriorating) 4 5
Immediate Attention 5 1 (until repaired or
rehabilitated)

The City may assess the condition of the manholes and other structures using City field crews and visual inspection methods during its system -wide sewer cleaning. Manhole inspection is noted on the Daily Crew Sheet; if there are any structural defects, unsanitary issues, roach/vermin issues, or surcharging/flow issues a Defect Sheet is filled out. A sample of the Daily Crew Report is included as Appendix D, and a Defect Sheet is included as Appendix E.

City crews conduct minor corrective maintenance; major repairs are typically contracted out.

The USD maintains a list of known structural deficiencies. The list is maintained in priority order. Urgent priority structural deficiencies, which may cause an SSO, are corrected as soon as possible.

Sewers and appurtenant structures are treated as needed to control infestations noted during regular inspections or identified through complaints.

Contract Services apply root control chemicals on an as-needed basis in order to reduce the rate of root growth and subsequent structural damage to the pipe. Application process es will vary depending on type of root control product used. Depending on the manufacture r’s guidelines, the pipe segments are cleaned as needed prior to application of the root control chemicals.

4.2.2 Reactive Maintenance

Reactive maintenance activities typically include investigation and response to complaints regarding a manhole overflow, missing or shifted manhole covers, manhole covers that are excessively noisy, sewer odor, etc. Sewer complaints received by the USD are typically investigated and appropriate actions are taken to identify the source of the problem and resolve the issue if possible.

4.2.3 Lift Station and Force Main

The City monitors the operation of its lift station using operational inspections and 27 | Page
alarms. The City conducts weekly operational inspections of the lift station and the wet well is cleaned by City staff as needed. Preventive maintenance for mechanical and electrical equipment is scheduled as appropriate according to manufacturer's specifications. The City monitors the pump discharge pressure during its operational inspections. The deposition of solids will cause the pump discharge pressure to gradually increase over time. The City will use this data to determine if and when the force main requires cleaning.

Lift Stations at City -owned facilities such as parks, stadiums, and event centers, are the sole responsibility of the PARCS Department. The Utility Services Division is available to assist with spill response, if necessary.

4.3 Rehabilitation and Replacement Plan

USD has a Rehabilitation and Replacement Program in place to:

a) Ensure the timely repair of sewer facilities in imminent danger of failure or blockage;

b)
Provide for the long-range replacement of obsolete or aging assets; and

c) Improve performance and reduce spills caused by pipe defects or mechanical failures.

The Rehabilitation and Replacement Program uses data from the City's CCTV inspection and available flow monitoring programs, as well as feedback from regular maintenance activities, to prioritize and schedule the rehabilitation and replacement projects.

When sufficiently damaged, deteriorated, or near capacity sewer facilities are identified, a CIP Project is developed. A short -term repair program would be completed in two years or less, while a long -term repair program would require longer than two years for completion. Priorities and timing are based upon necessity and available budget.

4.3.1 Gravity Sewers

City crews assess the condition of gravity sewers using CCTV and use the industry-standard PACP to assign a condition grade from 1 to 5. The results, in terms of the most severe defect found in each pipe, are shown on Table 4 which shows the ongoing condition assessment.

Total 2,903

4.3.2 Lift Station

Before the City took over the sewer system from Los Angeles County in July 2008, the lift station was found to be in good condition. Future lift station condition assessments will be conducted based on the Lift Station Checklist included in Appendix F-1. The results will be used to identify major maintenance and capital improvement projects. The crews shall also take and retain pictures of these facilities, and complete a defect sheet if any deficiencies are identified during the inspections. A comprehensive S.O.P for Lift Station Condition Assessment is used for regular inspections. The City will initiate an inspection program when the age of the force main approaches 30 years.

4.3.3 Capital Improvement Program

The City requested withdrawal from the CSMD in December 2006. In order to generate funds for maintenance and reconstruction of sewer system, the City Council established a sewer service charg e beginning in fiscal year 2007 -08. The sewer service charge is broken down into an O&M component and a capital replacement component. The sewer service charge is determined by multiplying the number of sewage units by the rate established by City Council. A single - family residence represents 1 (one) sewage unit and is the basis for determining sewage charge for other users. The amount of sewer service charge assessed is based on current land use. Current sewage units for designated land uses are identified in 'Table
A' of the Chapter 13.09.120 of the Lancaster Municipal Code.

The City is required to:
a) Set sewer service charges that meet on -going ope rating expenditures of the sanitary sewer system; and
b) Provide for the timely replacement and rehabilitation of existing infrastructure.

A portion of the sewer charges collected bi -annually through property tax rolls is set aside as funding for future CIP Projects. It is anticipated that both short - and long-term CIP Projects will be adequately funded through this source.

4.4 Training Program

4.4.1 City Staff

The City uses a combination of on- the-job training, conferences, seminars, and other training opportunities to provide technical training for its wastewater collection system staff. The City also requires each collection system worker to have obtained appropriate certification for their level of responsibility and to maintain that certification. Various training venues are provided to obtain the necessary continuing education credits for CWEA certifications. The safety -related training for the wastewater co llection crew members is specified in the City's Illness and Injury Prevention Plan maintained by the Human Resources Division. Vendors provide training for new equipment. Each person who is required to enter a confined space is provided with Confined Space training and certification on an annual basis.

Chapter 5 Design and Performance Provisions

Chapter 5 of this SSMP addresses the requirements included in Attachment D, Section 5 of the Order.

The requirements state:

Design and Performance Provisions:

a) Design and construction standards and specifications for the installation of new sanitary sewer: systems, pump stations and other appurtenances; and for the rehabilitation and repair of existing sanitary sewer systems; and

b) Procedures and standards for inspecting and testing the installation of new sewers, pumps, and other appurtenances and for rehabilitation and repair projects.

5.1 Design & Construction Standards and Specifications Documents

The City uses established guidelines for design and construction of new sanitary sewers, pump stations and appurtenances. The following is a summary of documents used by the City as design and construction standards and specifications.

5.1.1 Ordinance No. 910 (Sewer Ordinance)

City Ordinance No. 910 adopted Chapters 13.07, 13.08 and 13.09 as the City's Sanitary Sewer and Industrial Waste Ordinance. With respect to design and performance provisions, the ordinance includes regulations for design and permitting, installation, inspection, and maintenance. Article 3 of Chapter 13.08 (13.08.175 to 13.08.290) sets minimum standards for sewer diameter, pipeline grade, flow velocity, depth, house lateral design, manhole spacing and location, pipe material, and pipe and installation requirements. Article 4 (13.08.325 to

13.08.345) specifies City inspection procedures for sewer work and Article 5 (13.08.375 to 13.08.390) specifies maintenance provisions. For additional requirements, the ordinance refers to the Engineering Design Guidelines P olicies and Procedures, the Standard Specifications for Public Works Construction, and the City Standard Plans, which are described in more detail below along with other documents that the City uses. The ordinance requires that all designs and installations be prepared and approved by a registered civil engineer prior to approval by the City.

5.1.2 City Engineering Design Guidelines Policies and Procedures

The City's Engineering Design Guidelines, Policies and Procedures establish design guidelines for private development and public projects including sewer rehabilitation and repair projects, within the City. Section 2.4, Sewer Improvement Plans, of that document identifies design criteria for new sewer systems including lateral connections, sewer mains, manholes, and sewer loading criteria (unit flow factors). This section also includes the City's submittal requirements, sewer improvement plan checklist, standard sewer improvement plan notes, and testing, inspection, record drawings and dedication requirements, which would be included in the Contract Drawings and Special Provisions for sewer projects. 48 | Page

City's Engineering Design Guidelines, Policies and Procedures contain standard requirements for sewer rehabilitation and repair projects; however, the City also establishes project- specific design criteria for these projects because existing methods are co nstantly evolving, new methods are continually being developed, and each project is typically unique.

As needed, the City will update, change, or add specific guidelines for wastewater pump station design and plans and is considering the development of basic evaluation and design guidelines for rehabilitation and repair projects, such as pre- design inspection requirements, calculation requirements for various techniques, and identifying acceptable rehabilitation and repair methods.

5.1.3 Los Angeles County Department of Public Works Guidelines for Wastewater Pump Station Design and Plan Submittal Procedures

Los Angeles County's Guidelines for Wastewater Pump Station Design and Plan Submittal Procedures recommends minimum acceptable design and plan submittal requirements for wastewater pump stations. This document establishes plan requirements and calculation requirements for structural elements, estimates of flows, wet well design, head and surge, force main, noise, ventilation, and sizing of major pieces of equipment. Detailed design criteria are defined for wet wells and dry wells, force mains, valve vaults, access hatches, electrical and controls, pumps and motor, valves, emergency generators, air compressors, buildings and canopy and protective coatings. This document also specifies requirements for plan submittal, inspection, testing, record drawings, and acceptance (dedication), which would be included in the Contract Drawings and Special Provisions for sewer projects. Designs will be reviewed on a case -by-case basis and applicable modifications to the County guidelines made as determined by the City.

5.1.4 "Greenbook" Standard Specifications for Public Works Construction

The Greenbook, written by Public Works Standards, Inc. provides specifications that have general applicability to public works projects. Part 1 of the Greenbook specifies general provisions for construction. Parts 2 through 4 of the Greenbook specify requirements for construction materials, construction methods and inspection and testing procedures, which apply to pipelines (pressure and gravity), earthwork, structural work, electrical components (for pump station work) and coatings. Part 5 of the Greenbook specifies materials, construction methods and inspection and testing procedures for rehabilitation projects, including pipeline rehabilitation through point repairs and various liners, and manhole/structure rehabilitation.

Construction requirements for site improvements, structural, basic electrical work and earthwork for pump stations are covered in the Greenbook. Construction requirements for mechanical equipment, buildings, valves, backup power, and other special equipment are project -specific and would be covered in the Contract Drawings and Special Provisions.

49 | Page

5.1.5 Standard Plans for Public Works Construction and City Standard Plans

The Standard Plans for Public Works Construction is a compilation of standard plans for use in conjunction with the Greenbook standard specifications. Section 2 includes standard plans (details) for sewers and sanitation, including manholes/structures and pipe and appurtenances. The City Standard Plans, which are included as part of the Engineering Design Guidelines Policies and Procedures, contain pipeline trench details.

5.1.6 Contract Drawings and Special Provisions

For each design project, the City approves Contract Drawings and Special Provisions prepared and signed by a registered civil engineer that are specifically tailored for that facility. The Contract Drawings and Special Provisions supplement the Greenbook, the City Standard Drawings, and the Standard Plans for Public Works Construction to form the construction Contract Documents. As mentioned above, construction requirements for mechanical equipment, valves, backup power, and other special equipment for pump stations are specified in the Contract Drawings and Special Provisions.

5.1.7 Industry Standards, Codes and Regulations

In addition to the guidelines above, facility design and construction requirements incorporate a number of industry standards and applicable codes and regulations including, but not limited to:

 American Society of Mechanical Engineers (ASME) Standards;  American National Standards Institute (ANSI) Standards;  American Society for Testing and Material (ASTM) Standards;  American Water Works Association (AWWA) Standards;
 Hydraulic Institute (HI) Standards;
 American Concrete Institute (ACI) Standards;
 National Electric Code (NEC);
 National Electric Manufacturer's Association (NEMA) S tandards;  City Municipal Codes, including but not limited to the Electrical, Mechanical, Plumbing, Fire and Building Codes;
 California Plumbing Code;
 State of California Industrial Safety Orders; and
 Applicable State and Federal regulations.

5.2 Inspection and Testing Procedures

The City has established procedures for inspection and testing of new sanitary sewer systems and repair and rehabilitation projects, including gravity sewers, force mains, pump stations, pipeline and manhole repair and rehabilitation, and pump station upgrades and rehabilitation.

50 | Page
Inspection, testing, and acceptance criteria for sanitary sewers, force mains, manholes and lateral connections are specified in the City's Engineering Design Guidelines, Policies and Procedures, and in the Greenbook, as described above. The documents include requirements for submitting record drawings and photographic documentation of construction; cleaning requirements; testing of sewer lines and manholes; post- installation video inspection; soils testing; inspection of structure excavations; and backfill compaction testing. The project- specific Contract Drawings and Special Provisions include additional testing requirements, as applicable.

Inspection, testing and acceptance procedures for pump stations are described in the Guidelines for Wastewater Pump Station Design and Plan Submittal Procedures. The guidelines include requirements for submittal of record drawings, operation and maintenance manuals, and photographic documentation of construction; inspections by city as applicable for compliance with building, plumbing, mechanical and electrical cod es; factory test documentation for materials and equipment; functional tests of equipment witnessed by the manufacturer's representative, contractor, and City inspector; demonstration testing witnessed by the manufacturer's representative, contractor, and City engineer; and certified reports of noise testing. These requirements are written into project- specific “
Special Provisions”.

Appendix L – Private Property Damage Procedures

Customer Relations Guidelines

It is important for employees to communicate effectively and in a timely manner with the City's customers, especially in a sewage backup situation. How we communicate - on the phone, in writing, or in person - is how we are perceived.

Good communication wi th the homeowner results in greater confidence in our ability to address the problem satisfactorily, less time to resolve the claim, and less damage done to the property.

As a representative of the City, you will occasionally have to deal with an irate homeowner. A backup is a stressful event and even a reasonable homeowner can become irate should he/she perceive us as being indifferent, uncaring, unresponsive, or incompetent.

Although sometimes difficult, effective management of a sewage backup situation is critical. If it is not managed well, the situation can end up in a costly, prolonged process with the homeowner. We want the homeowner assured that we are responsive and that the homeowner's best interest is a top priority.

Communication Tips

a) Give the homeowner ample time to explain the situation or to vent. Show interest in what the homeowner has to say, no matter how many times you have heard it before, or how well you understand the problem.

b) As soon as possible, let the customer know that you will determine if the source of the sewer backup is in the sewer main and, if it is, will have it corrected as quickly as you can.

c) Acknowledge the homeowner's concerns. For example, if the homeowner seems angry or worried about property damage, say something like, "I understand you're concerned about the possible damage to your property, but a professional cleanup crew can restore the area, and if it is determined that the City is at fault, the property owner has the right to file a claim for any reasonable repairs or losses resulting from this incident".

d) Express regret for any inconveniences caused by the incident, but do not admit fault.

e) As much as possible, keep the homeowner informed on what is being done and will be done to correct the problem.

f) Keep focused on getting the job done in a very professional manner. Don't wander from the problem with too much unnecessary small talk with the homeowner.

g) Don't find fault or lay blame on anyone or the City.

h) Make sure someone follows up with a telephone call to ensure everything is being handled as it should be.

Before you leave, make sure the homeowner has the name and telephone number of someone at the City to call if he/she has questions or wants additional information. The customer information letter and the City claim form contains this information and you should take the time to review this with the homeowner. 52 | Page

Appendix N – Methods for Estimating Spill Volume

A variety of approaches exist for estimating the volume of a sanitary sewer spill. This appendix documents the three methods that are most often employed. The person preparing the estimate should use the method most appropriate to the sewer overflow in question and use the best information available.

Method 1 - Eyeball Estimate

The volume of small spills can be estimated using an "eyeball estimate". To use this method, imagine the amount of water that would spill from a bucket or a barrel. A bucket contains 5 gallons and a barrel contains 50 gallons. If the spill is larger than 50 gallons, try to break the standing water into barrels and then multiply by 50 gallons. This method is useful for contained spills up to approximately 200 gallons.

Method 2 - Measured Volume

The volume of small spills that have been contained can be estimated using this method. The shape, dimensions, and the depth of the contained wastewater are needed. The shape and dimensions are used to calculate the area of the spills and the depth is used to calculate the volume.

Figure 4 - Common Shapes and Dimensions

54 | Page
Step 1 Sketch the shape of the contained sewage (see images above) Step 2 Measure or pace off the dimensions
Step 3 Measure the depth at several location and select an average Step 4 Convert the dimensions, including depth, to feet Step 5 Calculate the area in square feet using the following formulas:

Rectangle: Area = Length (feet) x Width (feet)
Circle: Area = Diameter (feet) x Diameter (feet) x 0.79 Triangle: Area = Base (feet) x Height (feet) x 0.5
Step 6 Multiply the area (square feet) times the depth (feet) to obtain the volume in cubic feet
Step 7 Multiply the volume in cubic feet by 7.5 to covert to gallons

Method 3 - Duration and Flowrate

Calculating the volume of larger spills, where it is difficult or impossible to measure the area and depth, requires a different approach. In this method, separate estimates are made of the duration of the spill and the flowrate. The methods of estimating duration and flowrate are:

Duration: The duration is the elapsed time from the time the spill started to the time that the flow was restored.

Start Time: The start time IS sometimes difficult to establish. Here are some approaches:

a) Local residents can be used to establish start time. Inquire as to their observations.

b) Spills that occur in rights -of-way are usually observed and reported promptly. Spills that occur out of the public view can go on longer. Sometimes observations like odors or sounds (e.g. water running in a normally dry creek bed) can be used to estimate t he start time.

c) Changes in flow on a downstream flowmeter can be used to establish the start time.

d) Typically, the daily flow peaks are "cut off' or flattened by the loss of flow. This can be identified by comparing hourly flow data during the spill event with flow data from prior days.

e) Conditions at the spill site change over time. Initially there will be limited deposits of toilet paper and other sewage solids. After a few days to a week, the sewage solids form a light - colored residue. After a few weeks to a month, the sewage solids tum dark. The quantity of toilet paper and other materials of sewage origin increase over time. These observations can be used to estimate the start time in the absence of other information. Taking photographs to document the observations can be helpful if qu estions arise later in the process.

f) It is important to remember that spills may not be continuous. Blockages are not usually complete (some flow continues). In this case the spill would occur during the peak flow periods (typically 6 am to 9 am and 4 pm to 8 pm each day). Spills that occur d ue to inflow and infiltration in excess of capacity will occur only during, and for a short period after, heavy rainfall.

55 | Page
End Time: The end time is usually much easier to establish. Field crews on -site observe the "blow down" that occurs when the blockage has been removed. The "blow down" can also be observed in downstream flowmeters.

Flowrate: The flowrate is the average flow that left the wastewater collection system during the time of the spill. The flowrate is expressed in gallons per minute.

There are three common ways to estimate the flowrate:

a) The San Diego Manhole Flowrate Chart: This chart, included as Appendix N, shows sewage flowing from manhole covers at a variety of flowrates. The observations of the field crew can be used to select the appropriate flowrate from the chart. If possible, photographs are useful in documenting the basis for the flowrate estimate.

b) Flowmeter: Changes in flows in downstream flowmeters compared to their typical readings can be used to estimate the flowrate during the spill.

c) Counting Connections: Once the location of the complete blockage is known, the number of upstream connections can be determined from the sewer maps. Multiply the number of connections by 200 to 250 gallons per day per connection or 8 to 10 gallons per hour per connection.

For example:

22 upstream connections x 9 gallons per hour per connection = ~ 198 gallons per hour / 60 minutes per hour
= ~ 3.3 gallons per minute

Spill Volume: Once duration and flowrate have been estimated, the volume of the spill is the product of the duration in hours or days and the flowrate in gallons per hour or gallons per day.

For example:

Spill start time ~ 11:00
Spill end time ~ 14:00
Spill duration ~ 3 hours

3.3 gallons per minute x 3 hours’ x 60 minutes per hour ~ 594 gallons

Chapter 6 Spill Emergency Response Plan (SERP)

6.1 Purpose
The purpose of the City of Lancaster 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 documenting 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.

6.2 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.

6.3 Spill Emergency Response Plan and Response Workbook

The City’s Spill Emergency Response Plan (SERP) and Sewer Spill/Backup Response Workbook are included as Attachment 6.3.

Chapter 7 Sewer Pipe Blockage Control

Chapter 7 of this SSMP addresses the requirements included in Attachment D of the Order. The requirements state:

a) FOG Control Program: Each Enrollee shall evaluate its service area to determine whether a FOG control program is needed. If an Enrollee determines that a FOG program is not needed, the Enrollee must provide justification for why it is not needed. If FOG is found to be a problem, the Enrollee must prepare and implement a FOG source control program to reduce the amount of these substances discharged to the sanitary sewer system. This plan shall include the following as appropriate:

b) An implementation plan and schedule for a public education outreach program that promotes proper disposal of FOG:

c) A plan and schedule for the disposal of FOG generated within the sanitary sewer system service area. This may include a list of acceptable disposal facilities and/or additional facilities needed to adequately dispose of FOG generated within a sanitary sewer system service area;

d) The legal authority to prohibit discharges to the system and identify measures to prevent s and 60 | Page
blockages caused by FOG;

e) Requirements to install GRDs (such as grease traps or grease interceptors), design standards for the removal devices, maintenance requirements, BMP requirements, record keeping and reporting requirements;

f) Authority to inspect grease producing facilities, enforcement authorities, and whether the Enrollee has sufficient staff to inspect and enforce the FOG ordinance;

g) An identification of sanitary sewer system sections subject to FOG blockages and establishment of a cleaning
& maintenance schedule for each section; and

h) Development and implementation of source control measures for all sources of FOG discharged to the sanitary sewer system for each section identified in (f) above.

7.1 Extent and Nature of City FOG Control Program

City Ordinance No. 1066 implements FOG control measures within the City boundary. This section of the SSMP presents the extent and nature of SSOs related to FOG and the need for a FOG Control Program.

There are over 400 commercial FOG sources (FSEs) in the City's wastewater collection system service area (see Figure 2 -1). There are likely other FOG sources (e.g. churches, micro -kitchens, and single and multi-family) that are also discharging FOG to the City's sewer system. The City frequently cleans certain sewer lines known to be prone to blockages, in order to prevent SSOs due to the deposition of FOG and other causes. The City adds sewer lines to its preventive m aintenance program following blockages or SSO events and in response to observations of grease or other debris during CCTV inspections or during proactive cleaning of sewers.

The City's preventive maintenance approach to minimizing FOG- related SSO events has been effective. Through following our proactive plan, we experienced consistently less spill numbers and volumes per spill than the statewide and regional average SSOs, based on the Statewide SSO Reduct ion Program Report for FY 2022 /2023, which can be accessed at:

https://www.waterboards.ca.gov/about_us/performance_report_2223/plan_assess/124_sanitary_sewage_ov erflow.html

The City will remain proactive in ensuring that FOG-related SSOs are kept to a minimum by initiating additional FOG control measures to support/enhance its current efforts to control FOG in the sewer system. These efforts may include frequent ins pections of FSEs and community outreach.

7.2 FOG Control Program Activities

The City's FOG Control Program currently consists of providing preventive maintenance for its problematic gravity sewers. The City will continue to collect data related to sewer service calls, sewer cleaning activities, SSOs, and CCTV inspections to identi fy problematic gravity sewer lines. This data will be analyzed and problematic lines will be cleaned more frequently. Cleaning schedules for these sections will be determined based on severity, ranging from monthly to semi- monthly. The City will continue t o evaluate the effectiveness of its FOG Control Program and public outreach program during future SSMP updates. Table 6 lists the activities that the City includes in its current FOG Control Program.

7.2.1 FOG Preventive Maintenance

The City's preventive maintenance program will continue its focus on problematic sewer locations. The City will employ the methods outlined in Chapter 4 - Operations and Maintenance Program to optimize its preventive maintenance activities. Additionally, the FOG control program will continue to participate in community outreach including community partner meetings, attendance at community events, and regular review of business licenses in order to provide education and training along with ens uring new businesses are properly evaluated for their potential participation.

7.2.2 GRD Installation, Design, Maintenance, and Record Keeping

The City has developed and implements a robust FOG control program starting from project planning, design, construction and commissioning, which proactively prevents discharge of FOG in City's sewer lines. The City has adopted Muni cipal Code Section 13.10 and can use that authority to require new, remodeled or problematic FSEs to install GRDs .

7.3 FOG Disposal Facilities

The list of approved waste oil/grease haulers can be found at:
https://apps1.cdfa.ca.gov/IKG/Transporters.aspx
Additionally, the City of Lancaster accepts waste oil for drop -off only at the City Maintenance Yard located at 615 W Avenue H, Lancaster, CA 93534. For additional information you may call (661) 723-5985.

7.4 Staffing

The City maintains a staffing adequate to perform routine maintenance and respond to an SSO. A minimum of four utility maintenance workers are on staff during all regular work day. Inspectors are also utilized for FSE FOG ins pections.

Chapter 8 System Evaluation, Capacity Assurance and Capital Improvements

Chapter 8 of this SSMP addresses the requirements included in Subsection D.13. (viii) of the Order.

The requirements state:

a) Evaluation: Actions needed to evaluate those portions of the sanitary sewer system that are experiencing or contributing to an SSO discharge caused by hydraulic deficiency. The evaluation must provide estimates of peak flows (including flows from SSOs that escape from the system) associated with conditions similar to those causing overflow events, estimates of the capacity of key system components, hydraulic deficiencies (including components of the system with limiting capacity) and the major sources that contribute to the peak flows associated with overflow events;

b) Design Criteria: Where design criteria do not exist or are deficient, undertake the evaluation identified in (a) above to establish appropriate design criteria; and

c) Capacity Enhancement Measures: The steps needed to establish a short-term and long- term CIP to address identified hydraulic deficiencies, including prioritization, alternatives analysis, and schedules. The CIP may include increases in pipe size, inflow and infiltration (III) reduction programs, increases and redundancy in pumping capacity, and storage facilities. The CIP shall include an implementation schedule and shall identify sources of funding.

d) Schedule: The City shall develop a schedule of completion dates for all portions of the capital improvement program developed in (a) - (c) above. This schedule shall be reviewed and updated consistent with the SSMP review and update requirements as describ ed in Section D.14 (of the GWDR).

8.1 Capacity Evaluation

As part of the original SSMP written in 2009, a comprehensive capacity evaluation using a dynamic hydraulic model was performed to quantify flows and capacities in all major sewers under current and future flow conditions. This evaluation and its findings are documented in the report:

City of
Lancaster Sewer Master Plan, September 2009 (Master Plan).

The conclusion of the capacity evaluation was that Lancaster's sewer system has adequate capacity for current and future flows through at least 2030, and that no capital improvements are required at this time for the purpose s of increasing sewer capacity. However, upon re -evaluation of the system based on operational knowledge, an updated comprehensive capacity evaluation should be performed prior to 2025.

In the event that new sanitary sewer projects are proposed, the City's Engineering Design Guidelines, Policies and Procedures provide guidelines for public and private development. Section

2.4 of that document identifies design criteria for new sewer systems including unit flow factors, peaking factors, hydraulic friction factors, minimum slopes, and maximum allowable depth of flow. Prior to the approval of new sewers, the City requires that developers perform a sewer area study that applies these criteria to confirm the adequacy of the proposed sewers.

8.2 Capacity Enhancement Measures and Schedule

Because of the uncertainty in the wet weather flow estimates and the potential for capacity problems in the CSD -14 system in the future, the City has installed surcharge monitors at ten locations inside sewer manholes that are predicted to surcharge, as well as in City manholes that are closest to exceeding capacity criteria. The monitor locations are described in the Master Plan and may be modified over time as initial data is gathered and assessed. These monitors will be checked after major storms to determine if surcharging actually occurred. The City will share its modeling and monitoring findings with CSD -14, who are responsible for ensuring that the trunk sewers have adequate capacity.

8.3 Capital Improvement Program

The City maintains a robust CIP. When sufficiently damaged, deteriorated, or near capacity sewer facilities are identified, a CIP Project is developed. A short- term repair program would be completed in two years or less, while a long term repair program would require longer than two years for completion. Priorities and timing are based upon necessity and available budget. Slip lining, point repair, pipe bursting, and replacement are included as methods that may be employ ed to improve the sewer system.

Chapter 9 Monitoring, Measurement, and Program Modifications

Chapter 9 of this SSMP addresses the requirements included in Attachment D-9 of the Order. The requirements state:

a) Maintain relevant information that can be used to establish and prioritize appropriate SSMP activities;

b) Monitor the implementation and, where appropriate, measure the effectiveness of each element of the SSMP;

c) Assess the success of the preventative maintenance program;

d) Update program elements, as appropriate, based on monitoring or performance evaluations; and

e) Identify and illustrate SSO trends, including: frequency, location, and volume.

9.1 Performance Measures

Performance measures show average annual basic maintenance measurements and SSO data. The indicators that the City uses to measure the performance of its wastewater collection system and the effectiveness of its SSMP are:

a)
Total number of SSOs and SSO rate per 100 miles per year;

b) Portion of SSOs for each cause (roots, grease, debris, rags, pipe failure, capacity, lift station failure, vandalism, and other);

c) Portion of sewage contained compared to total volume spilled,

d) Portion of spilled sewage discharged to surface water, and

e) Planned to actual performance for preventive maintenance as a percentage.

Table 7 below shows basic historical maintenance measurements and SSO data over the past six years.

It can be seen that the City's rate of SSOs has decreased over the years and the percentage of runoff contained has risen. The City’s preventive maintenance and inspections detect problems prior to a surcharge, and community outreach has helped to prevent these spills from occurring in the first place. Additionally, staff’s quick response time and exceptional training ensure the spill volumes in SSOs are minimal.

Chapter 11 of the SSMP addresses requirements included in Subsection D. 13. (xi) of the Order.

Requirements state:

a) The Enrollee shall communicate on a regular basis with the public on the development, implementation, and performance of its SSMP. The communication system shall provide the public the opportunity to provide input to the Enrollee as the program is developed and implemented.

b) The Enrollee shall also create a plan of communication with systems that are tributary and/or satellite to the Enrollee's sanitary sewer system.

11.1 Communication during SSMP Development and Implementation

The City posted a notice on its website to inform interested members of the public that it has developed an SSMP. The City will make the SSMP documents and contact information available for review at the City Hall located at 44933 Fern Avenue, and at the Maintenance Yard located at 615 W. Avenue H, and will post them on the City's website at www.cityoflancasterca.org. The City will also post updates to the SSMP on this website to keep interested citizens informed of progress.

11.2 Communicating Sanitary Sewer System Performance

The City reports s electronically to the CIWQS. The URL for the CIWQS public access site is:

https://www.waterboards.ca.gov/ciwqs/publicreports.html

The City will report the performance of its sanitary sewer system to the City Council each year at a regularly scheduled meeting, and the performance information shall be included in the minutes of that public meeting.

Once accepted by City Council, the City posts i nformation on the performance of its sanitary sewer system on its website. The information includes the performance indicators listed in Section 9 – MMPM and is compiled annually.

11.3 Communication with Tributary/Satellite Sanitary Sewer System City sewers convey flow from a small number of connections owned by customers of the Los Angeles County Department of Public Works and the CSMD. The CSMD flow represents less than 1 % of the total flow moving through City sewer lines.

1. PURPOSEThe purpose of the City of Lancaster 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 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.

City of Lancaster Spill Emergency Response Plan 5-25-23 © 2004-2023 DKF Solutions Group, LLC. All rights reserved. Page 5 of 49 DRAINAGE CONVEYANCE SYSTEM: A drainage conveyance system is a publicly- or privately-owned separate storm sewersystem, 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.

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. The Sewer System Management Plan is available to the public at https://www.cityoflancasterca.org/our-city/depart-ments-services/development-services/utility-services/sewer-collection-system/sewer-system-management-plans .

5. SPILL EMERGENCY RESPONSE PLAN OBJECTIVESThe 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 one wastewater lift stations. In the event of a station failure the SCADA alarm system is acti-vated and the City is contacted. An overflow or other significant alarm at the pump station requires a site visit. In the event that an SSO has occurred or is imminent due to a pump station failure, the first responder should use their professional experience and judgment to determine if it is necessary to call for assistance. The first responder should initiate and organize delivery of portable pumping units (including fuel), hoses, portable lights, and appropriate traffic control devices, if required. 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 OBSERVATIONPublic 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: Emergency Contact Information | City of Lancaster (cityoflancasterca.org). The City’s telephone number for reporting sewer problems is (661) 723-5985during regular business hours or the Sheriff's Department at(661) 948-8466after hours, weekends, and holidays. Normal Work Hours: Calls 7:00 to 5:00 Monday thru Thursday and 7:00 to 4:00 Friday are received at the main district office. The main office will notify the Field Crew via phone and will send an email to the Field Crew with caller information (name, address, phone, nature of complaint). After Hours: After hours call the Sheriff’s Department and the Sheriff Dispatcher receives the call, takes the information from the caller, and communicates it to the Public Works Standby Crew at (661) 510-4362. 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. If the spill or backup is in the City’s service area, the Field Crew (during business hours) or standby employee (after hours) will respond to the address of the complaint and do an investigation. If the complaint is not a spill, the crew members’ findings and actions taken, if any, are logged into the City Computerized Maintenance Man-agement System (CMMS) or work order system. If after hours it is entered into the standby activity log using a field laptop if available. If a field laptop is not available, the information will be entered into CMMS, the work order system, or the standby activity log when the employee returns to the City. If the complaint is a spill, the crew member will complete the Sanitary Sewer Spill and Backup Response Workbook and then enter the findings and actions taken into the City’s CMMS, work order system, or standby activity log. 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 Permit Technician Staff when they pull a permit. The following procedures are to be followed in the event that a contractor/plumber causes or witnesses a sanitary sewer spill. If the contractor/plumber causes or witnesses a spill they should: 1. Immediately notify the City at 661-723-5985 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 2. Protect storm drains. 3. Protect the public. 4. Direct ALL media and public relations requests to the Communications Department at 661-723-6000. 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 Field Crew performs the following: Follows the instructions in the Sanitary Sewer Spill/Backup Response Workbook. If the customer is not home the Field Crew completes the Door Hanger and leaves it on the customer’s door. If the customer is home the Field 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 Field Crew:

Page 12 of 49 Follows the instructions in the Sanitary Sewer Spill/Backup Response Workbook. Notifies Assistant Director or Public Works Supervisor of the incident. Relieves blockage and cleans impacted areas. Forwards the completed Sanitary Sewer Spill/Backup Response Workbook to the Public Works Supervi-sor. Benjamin Stewart, Supervisor - Utility Services 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 Field Crew: 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 Public Works Supervisor. The Public Works Supervisor notifies the Risk Manager of incident. The Risk Manager or designee: Reviews incident reports, claim form and other incident information and forwards, as appropriate, to Allied World Insurance. Communicates with claimant as appropriate. Communicates with Allied World Insurance 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 Public Works Supervisor, or Assistant Director, or Lead Utility Workers 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 SAFETYThe 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 (SSS-WDR), the City provides written documentation of access restrictions and/or safety hazards in the corresponding 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.

City of Lancaster Spill Emergency Response Plan 5-25-23 © 2004-2023 DKF Solutions Group, LLC. All rights reserved. Page 14 of 49 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 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 Public Works Supervisor, or Assistant Director, or Lead Utility Workers. 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. 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 Public Works Maintenance Yard.

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 Field 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 DISINFECTIONClean 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. 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 Cal OES for spills greater than or equal to 1,000 gallons. For spills less than 1,000 gallons, contact County of Los Angeles, Department of Public Health, Environmental Health for direction. 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. County of Los Angeles, Department of Public Health, Environmental Health instructions and directions regarding placement and language of public warnings will be followed. Additionally, the Supervisor or Lead Utility Maintenance Worker will use their best judgment regarding supplemental sign placement in order to protect the City of Lancaster
Spill Emergency Response Plan 5-25-23

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.

In the event that an overflow occurs at night, the location will be inspected first thing the following day. The field crew will look for any signs of sewage solids and sewage-related material that may warrant additional cleanup activities.

When contact with the local media is deemed necessary, the Communications Department or their designee will provide the media with all revelvant information.

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. 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.

City of Lancaster Spill Emergency Response Plan 5-25-23 © 2004-2023 DKF Solutions Group, LLC. All rights reserved. Page 20 of 49 Receiving Surface Water Sampling (RSW)1Sampling 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. 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. 1The 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.

City of Lancaster Spill Emergency Response Plan 5-25-23 © 2004-2023 DKF Solutions Group, LLC. All rights reserved. Page 21 of 49 Field BlanksField 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 con-tainers 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. 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 Public Works Maintenance Yard. The kit is inspected quar-terly by the Environmental Senior Specialist. Additionally, any City employee utilizing the kit is responsible for decontaminating 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, preserved 10 Bacti sample bottles: 6 for samples (3 sets of duplicates), 2 for Field Blanks and 1 extra in the event of contamination, or other contingency 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 Field Crew in a “ready to be used” condition by the lab) used at the City may be summarized as follows:

1. Physical removal2. Tap water rinse 3. Air dry 9.12 SAMPLING PROCEDURES 9.12.1 Sample Location and Identification Procedures Samples will be collected by the Environmental Senior Specialist. It is impossible to establish hard and fast rules concerning sampling locations. However, the following general guidelines should be applied when-ever 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. 9.12.3 Follow Up Sampling Sampling will be repeated every 24 hours, or as directed by the RWQCB or the Los Angeles County De-partment of Environmental Health, until such time as one of the following criteria have been met: The Los Angeles County Department of 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.

City of Lancaster Spill Emergency Response Plan 5-25-23 © 2004-2023 DKF Solutions Group, LLC. All rights reserved. Page 24 of 49 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. 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.

City of Lancaster Spill Emergency Response Plan 5-25-23 © 2004-2023 DKF Solutions Group, LLC. All rights reserved. Page 30 of 49 These complaint records include, but are not limited to, records documenting how the City responded to notifi-cations of spills. Each complaint record must, at a minimum, include the following information: 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; All complaint records will be maintained for a minimum of five years whether or not they result in a spill. Spill files (field notes, spill/Backup Response Workbook) are kept electronically on the City H Drive. 11. POST-SPILL ASSESSMENTS OF SPILL RESPONSE ACTIVITIES (ref. 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, City of Lancaster Spill Emergency Response Plan 5-25-23 © 2004-2023 DKF Solutions Group, LLC.

The following procedures will be observed for all sewer overflows/backups into/onto private property: City staff will offer a City claim form irrespective of fault whenever it is possible that the sanitary sewer backup may have resulted from an apparent blockage in the City-owned sewer lines or whenever a City customer re-quests a claim form. The claim may later be rejected if subsequent investigations into the cause of the loss indi-cate the City was not at fault. It is the responsibility of the Field Crew to gather information regarding the incident and notify the Public Works Supervisor or their designee. It is the responsibility of the Risk Management or their designee to review all claims and to oversee the adjust-ment and administration of the claim to closure. 14.

Key Definitions & Category Determination A-3 : Page 1

NOTE: All references to “SSWDR” refer to State Water Board Order No. WQ 2022-0103-DWQ.

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 duri ng dry conditions. Waters of the State include waters of the United States.

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 “Y our 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.
• Leave a message on the customer’s voicemail.

6. If the property owner is unable or unwilling to address the cause of the Spill , immediately contact your supervisor and discuss whether Code Enforcement, the County Department of Environmental Health or Regional Water Quality Control Board should be notiﬁed.

1. Document the service call according to City procedures.

2. STOP. Do not continue to P AGE 2
Go to PAGE 2

1. Document arrival time.

2. Consider the need to call out additional staﬀ, contractor or mutual aid assistance .

3. If it is possible that this is a Category 1 spill greater than or equal to 1,000 gallons or a Category 2 spill that is threat ening to discharge to waters of the State , immediately make the 2 -hour notiﬁcation to Cal OES and obtain a control number.

BEGIN DIVERSION AND CONT AINMENT, AS NECESSARY

1. DIVERT AWA Y 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 .

Volume Estimation Computations & Examples E-1: Page 1
Miscellaneous Computations & Examples

To convert inches to feet
(NOTE: for the purposes of
this worksheet, the unit of
measurement will be in
feet for formula examples)
Divide the inches by 12 or use the chart on the right.

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.

Area/Volume of a Rectangle or Square
Formula: Length x Width x Depth = Volume in cubic feet

25' X 12' X 0.14' = 42 Cubic Feet
Length Width Depth Volume

Multiply the volume by 7.48 gallons to determine the volume in gallons:

Volume gal/ft3 Volume

Area/Volume of a Right Triangle
Formula: Base x Height x Depth = Volume in cubic feet

0.5 X 45' X 10' X 0.05' x 7.48 = 84.15 gallons Base Height Depth gal/ft3 Volume

Area/Volume of a Circle

STEP 2: Draw/sketch the outline (footprint) of the spill. Then break the footprint down into recognizable shapes.

Label/identify each sketch outline area (Area 1, Area 2, etc.) See example below.

STEP 3: Calculate the area of the footprint by completing the table below for each area in Step 2. Measure actual depth of standing sewage whenever possible. When depth varies, measure several representative sample points, and determine the average. If the depth is not measurable because it is only a wet stain, use the following estimated depths: Depth of a wet stain on concrete surface: 0.0026' (1/32") Depth of a wet stain on asphalt surface: 0.0013' (1/64") Rectangles:

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 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 Field Crew may advise you to consider relocating temporarily while the living area is cleaned. In that case, if the City is found to be responsible for the backup you may submit a claim for reimbursement of reasonable lodging for one night. Additional lodging and other expenses may be discussed with Risk Management.

To discuss this matter, contact the City Clerk’s Office at 661-723-6020. To submit a claim for damages contact the Risk Manager at 661-723-6015 .

Your Responsibilities as a Private Property Owner (Backup Only) F-4: 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.”

Spill cleanup inside the home:

For large clean ups, a professional cleaning firm should be contacted to clean up impacted areas, If you hire a contractor, it is recommended to get estimates from more than one company. 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.

Sus Responsabilidades Como Propietario de Una Propiedad Privada F-4 Página 1: en español

Cómo funciona un sistema de alcantarillado
Las tuberías de alcantarillado de un propietario se denominan servicios laterales y están conectadas a líneas troncales principales y regionales locales más grandes. 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 rápid amente, 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.

Limpieza de derrames dentro de la casa:

Para grandes limpiezas, se debe contactar a una empresa de limpieza profesional para limpiar las áreas afectadas. Si contrata a un contratista, se recomienda obtener estimaciones de más de una compañía. A veces, el seguro del propietario de vivienda pagará la limpieza necesaria debido a las reservas de alcantarillado. No todas las pólizas tienen esta cobertura, así que consulte con su agente.

Si decide limpiar un pequeño derrame dentro de su casa, protéjase de la contaminación observando las siguientes medidas de seguridad. Aquellas personas cuya resistencia a la infección esté comprometida no deben intentar este tipo de limpieza.

Otros consejos:
o Mantenga a los niños y mascotas fuera del área afectada. o Apague los sistemas de calefacción / aire acondicionado o Use botas de goma, guantes de goma y gafas durante la limpieza. o Deseche los artículos que no se puedan lavar y desinfectar (como: colchones, alfombras, cosméticos, juguetes, etc.)
o Retire y deseche los paneles de yeso y el aislamiento contaminado con aguas residuales o aguas de inundación.
o Limpie a fondo todas las superficies duras (como pisos, concreto, molduras, muebles de madera y metal, mostradores, electrodomésticos, fregaderos y otros accesorios de plomería) con agua caliente y ropa o detergente para platos.
o Ayude al proceso de secado con ventiladores, unidades de aire acondicionado y deshumidificadores. o Después de completar la limpieza, lávese las manos con agua y jabón. Use agua que haya sido hervida por 1 minuto (deje que el agua se enfríe antes de lavarse las manos) O use agua que haya sido desinfectada (solución de 1/8 cucharadita de lejía doméstica por 1 galón de agua). Dejar reposar durante 30 min. Si el agua está turbia, use ¼ cucharadita de lejía de uso doméstico por 1 galón de agua. o Lave la ropa usada durante la limpieza con agua caliente y detergente (lave aparte de la ropa no contaminada).
o Lavar la ropa contaminada con aguas residuales en agua caliente y detergente. Considere usar una lavandería hasta que su sistema de aguas residuales en el sitio haya sido inspeccionado y reparado profesionalmente.

Limpieza de derrames fuera de la casa:
o Mantenga a los niños y las mascotas fuera del área afectada hasta que se haya completado la limpieza. o Use botas de goma, guantes de goma y gafas protectoras durante la limpieza del área afectada. o Limpie los sólidos de alcantarillado (material fecal) y colóquelos en un inodoro o bolsa doble que funcione correctamente y colóquelos en un contenedor de basura.
o En áreas de superficies duras como el asfalto o el concreto, es seguro usar una solución de lejía al 2%, o ½ taza de lejía a 5 galones de agua, pero no permita que llegue a un drenaje de tormenta ya que la lejía puede dañar la ambiente.
o Después de la limpieza, lávese las manos con agua y jabón. Use agua que haya sido hervida por 1 minuto (deje enfriar antes de lavarse las manos) O use agua que haya sido desinfectada (solución de 1/8 cucharadita de cloro por 1 galón de agua). Dejar reposar durante 30 min. Si el agua está turbia, use ¼ cucharadita de lejía de uso doméstico por 1 galón de agua. o Lave la ropa usada durante la limpieza con agua caliente y detergente (lave aparte de la ropa no contaminada).
o Lavar la ropa contaminada con aguas residuales en agua caliente y detergente. Considere usar una lavandería hasta que su sistema de aguas residuales en el sitio haya sido inspeccionado y reparado profesionalmente.

Busque atención
inmediata si se lesiona
o se enferma durante
o después del proceso
de limpieza.

Surface water sampling helps to ensure water quality by identifying areas of concern and potential failure mechanisms that may impact surface waters or stormwater infrastructure in the service area.

Minimize Impacts
Surface water sampling allows for the proper evaluation of potential contamination following a sanitary sewer
spill.

Having a thorough understanding of the service area and its various challenges can help responders be better prepared to minimize the impacts of a spill on local surface waters and stormwater infrastructure.

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.

Personal Protective Equipment
Personal Protective Equipment (PPE) should be used when conducting surface water sampling. The PPE that is required includes:
• Gloves
• Eye Protection

Sampling Equipment

In addition to PPE, other sampling equipment is necessary:
• Sample Bottles & Containers
• Cooler with Ice, or Ice packs
• Sampling Pole, or
• Rope & Bucket

The use of PPE and proper sampling equipment is important for the safety of the sampler and for ensuring accurate and reliable sampling results.

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 2 of 4
Identify the point of the spill where the wastewater entered the waterway and take a photograph of this location with a reference point in the picture.

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.

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.

Step 1 of 9
Don the appropriate PPE from your sampling kit. 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.

Step 4 of 9
Remove the seal from the Ammonia sample container just
prior to collecting your sample, as applicable.

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.

Surface Water Sampling SOP: Surface Water Sampling G-6: Page 4

Step 7 of 9
Fill the Ammonia sample bottle to the fill line, and
immediately replace the cap. If there is no clear fill line, fill it to the “neck” of the bottle.

Acquire samples from each location.

Step 8 of 9
Open the Bacteria sample container and allow water to
gently flow into the bottle just to the fill line.

Acquire samples from each location.

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.

Step 1 of 4: Documentation
All samples must be labeled with their location, your name, and the date and time they were collected. Refer to the state requirements found on the last page of this document.

Record this information on the chain of custody form and the surface water sampling worksheet.

Chain of Custody Record Surface Water Sampling Worksheet

Step 2 of 4: Contact the Lab
Inform the lab that the following samples require processing: ammonia -nitrogen and total/fecal coliform. Provide any additional information the lab may require.

Step 3 of 4: Transport Samples
Place the samples in the cooler on the ice pack and transport them to the lab within 6 hours of collection time. Complete the chain of custody form and ensure all samples are properly secured during transport.

Step 4 of 4: Post Warning Signs
If directed by your supervisor or the county environmental health division, post warning signs in the affected area. Keep track of sign locations and remove warning signs and lift restrictions only when authorized to do so.

The Enrollee shall collect receiving water samples
at the following locations:
