CITY OF NATIONAL CITY SEWER SYSTEM MANAGEMENT PLAN PAGE 11 Chapter 4: Operation and Maintenance Program
The City follows an Operation and Maintenance Program that includes the required items below as listed in the SSSWDR Attachment D, Section 4.
4.1 Updated Map of Sanitary Sewer System
(1) An up-to-date map(s) of the sanitary sewer system, and procedures for maintaining and providing State and Regional Water Board staff access to the map(s). The map(s) must show gravity line segments and manholes, pumping facilities, pressure pipes and valves, and applicable stormwater conveyance facilities within the sewer system service area boundaries;
The City maintains an up-to-date Geographic Information System (GIS) database of the sanitary sewer system, including all gravity line segments and manholes, pumping stations, pressure pipes and valves, as well as direction of flow and material when available. This database was used by D-MAX Engineering, Inc. to create a map of the City’s existing wastewater facilities and pipes, as shown in Appendix D. Manhole identifications shown on the maps are catalogued in the Sewer Manhole Index. This index lists all Cityowned manholes, along with their invert elevations and an associated direction identified (i.e. N, S, E and/or W). A pdf map of applicable storm water conveyance facilities is maintained by the Storm Water Division of the Engineering and Public Works Divisions.
4.2 Preventive Operation and Maintenance Activities
(2) A scheduling system and a data collection system for preventive operation and maintenance activities conducted by staff and contractors. The scheduling system must include:
• Inspection and maintenance activities;
• higher-frequency inspections and maintenance of known problem areas, including areas with tree root problems; and
• regular visual and closed-circuit television (CCTV) inspections of manholes and sewer pipes.
(3) The data collection system must document data from system inspection and maintenance activities, including system areas/components prone to root-intrusion potentially resulting in system backup and/or failure.
The City is committed to a regular sanitary sewer maintenance program in order to reduce and prevent spills and to extend the useful life of the system. This includes routine maintenance and cleaning of wastewater facilities and pipelines. These procedures are documented in the Sewer Operations, Maintenance, and Repair Program SOP (Appendix
CITY OF NATIONAL CITY SEWER SYSTEM MANAGEMENT PLAN PAGE 12 D). The City has divided its sewerage system into 11 sections for routine maintenance and cleaning. Approximately one section is cleaned each month, which ensures that all gravity mains in the City are cleaned at least once per year. Sections of the sewer system that require more frequent cleaning are identified on the high frequency maintenance list.
The list includes fats, oils, and grease (FOG) problem areas that require at least monthly cleaning and maintenance. These hotspots are presented in the sewer cleaning frequency map (Appendix D). City staff also conducts visual inspections of the manholes and pipes as part of the cleaning protocol. Closed circuit televising (CCTV) of manholes and sewer pipes are done based on these observations. Known problem areas and complaint issues are prioritized for video inspection.
Additionally, the City inspects and maintains two force mains. The force main at 14th Street and Tidelands Avenue is a very short segment and can be easily accessed via manhole inspection. The force main at 24th Street (Bay Marina Drive) and Tidelands Avenue is inspected at least twice per year. It should be noted that this force main is not always used on daily basis. The City’s two pump stations at these locations are inspected every business day. A pump station operation and maintenance SOP was developed in August 2016 for each pump station location and is included in Appendix D. An Emergency Response Plan specific to these pump stations was also developed in December 2023 and is included in Appendix D. A hard copy of the pump station SOP and appendices is kept in the Public Works office.
The City documents the Preventative Maintenance (PM) program of scheduled and conducted activities in several ways. A typical monthly schedule for maintenance and cleaning of wastewater facilities and pipes is provided in the City’s Wastewater Division Basic Work Schedule packet (Appendix D). This packet includes the forms used to document manhole inspections and sewer cleaning. The Sanitary Sewer Manhole Inspection Form and the Sewer Cleaning Log Form are completed by sewer staff following cleaning activities. Additionally, the sewer staff records activities in daily log books. Sewer related complaints are tracked using the Work Request Form. Finally, CCTV printouts with photos are generated following each video inspection.
Cleaning and maintenance schedules are reviewed and adjusted as necessary upon completion of sewer televising and after spills. Sites are added to the High Frequency Maintenance List as necessary. The current list of sewer hotspots has been digitized and is updated as needed to help aid in program planning. Additionally, the FOG inspection program results are tracked in an electronic database, and may be used to compare to the list of priority cleaning locations.
CITY OF NATIONAL CITY SEWER SYSTEM MANAGEMENT PLAN PAGE 13
4.3 Training

A spill Reporting Flowchart is included as Attachment 5. (12) Conduct post-spill assessments of spill response activities; Spill post-spill assessments are addressed in Section 5 of the SERP. A Spill Reporting Form is included as Attachment 5 and documents actions taken to prevent future spills. (13) Document and report spill events as required in this General Order; and Spill notification and reporting procedures are discussed in Section 4 of the SERP including all documentation and reporting requirements. (14) Annually, review and assess effectiveness of the Spill Emergency Response Plan, and update the Plan as needed.
Spill reviews are addressed in Section 5 of the SERP. Updates to the Plan are made as necessary. The SERP is also reviewed and updated as needed during audits of the SSMP.
The SERP also complies with the additional notification requirements outlined in RWQCB Order R9-2007-0005, Waste Discharge Requirements for Sewage Collection Agencies in the San Diego Region. These include:
(1) For Category 1 SSOs, the Sewage Collection Agency shall provide notification of the spill to the Regional Board by phone, email, or fax within 24 hours after the City becomes aware of the spill, notification is possible, and notification can be provided without substantially impeding cleanup or other emergency measures. The information reported to the Regional Board shall include the name and phone number of the person reporting the spill, the responsible sewage collection agency, the estimated total sewer overflow volume, the location of the spill, the receiving water (if any), the start date/time of the spill (or whether or not the sewer overflow is still occurring at the time of the report), and confirmation that the local health services agency was or will be notified as required under the reporting requirements of the local health services agency.
CITY OF NATIONAL CITY SEWER SYSTEM MANAGEMENT PLAN PAGE 19 (2) The Sewage Collection Agency shall provide notification of all Private Lateral Sewage Discharges (as defined in the State Board Order), for which they become aware of, that equal or exceed 1,000 gallons; result in a discharge to a drainage channel and/or surface water; and/or discharge to a storm drainpipe that was not fully captured and returned to the sanitary sewer system, to the Regional Board by phone or fax within 24 hours after the City becomes aware of the Private Lateral Sewage Discharge, notification is possible, and notification can be provided without substantially impeding cleanup or other emergency measures. The information reported to the Regional Board shall include the following information, if known: the name and phone number of the person reporting the Private Lateral Sewage Discharge, the service area where the Private Lateral Sewage Discharge occurred, the responsible party (other than the Sewage Collection Agency, if known), the estimated Private Lateral Sewage Discharge volume, the location of the Private Lateral Sewage Discharge, the receiving water (if any), the start date/time of the Private Lateral Sewage Discharge (or whether or not the sewer overflow is still occurring at the time of the report), and confirmation that the local health services agency was or will be notified as required under the reporting requirements of the local health services agency.
(3) The following requirement supersedes the Private Lateral Sewage Discharge Reporting Timeframe for Private Lateral Sewage Discharge in the State Board Monitoring and Reporting Program No. 2022-0103-DWQ: For Private Lateral Sewage Discharges that occur within a Sewage Collection Agency’s service area and that a Sewage Collection Agency becomes aware of, the Sewage Collection Agency shall report the Private Lateral Sewage Discharge to the State Board Online spill Database within 30 days after the end of the calendar month in which the Private Lateral Sewage Discharge occurs. The Sewage Collection Agency must identify the sewage discharge as occurring and caused by a private lateral, and responsible party (other than the Sewage Collection Agency) should be identified, if known. The City will not be responsible for the cause, cleanup, or repair of Private Lateral Sewage Discharges, but only the reporting of those within their jurisdiction and for which they become aware of.
CITY OF NATIONAL CITY SEWER SYSTEM MANAGEMENT PLAN PAGE 20 Chapter 7: Sewer Pipe Blockage Control Program
The Sewer System Management Plan must include procedures for the evaluation of the Enrollee’s service area to determine whether a sewer pipe blockage control program is needed to control fats, oils, grease, rags and debris. If the Enrollee determines that a program is not needed, the Enrollee shall provide justification in its Plan for why a program is not needed.
The City’s Fats, Oils and Grease (FOG) Control Program addresses the mandatory SSMP provisions outlined in the SSSWDR Attachment D, Section 7. The City’s FOG Control Program helps reduce the amount of pipe-blocking substances discharged to the sanitary sewer system as described below.
The procedures must include, at minimum:
(1) An implementation plan and schedule for a public education outreach program that promotes proper disposal of pipe-blocking substances;
The City is committed to reducing the amount of pipe-blocking substances discharged to the sanitary sewer system through the implementation of an effective public outreach program to food service and manufacturing establishments (FSEs) and to residents. The City’s Engineering Division annually updates new food service locations within the City’s service area based on business license registration. FOG compliance inspections are conducted at selected FSEs as part of the City’s FOG Inspection Program. High priority facilities are routinely selected for inspection. These include FOG-producing facilities that are in close proximity to known FOG hotspots and sites that failed to comply during the last inspection. Additional FSEs are selected for inspection each year based on time elapsed since their most recent inspection, historical inspection results, FOG generation potential, or other factors pertinent to the City’s sewer system management program implementation. The City may also utilize a FOG BMP Operation and Maintenance SelfVerification process where deemed appropriate and effective; a copy of the FOG BMP Operation and Maintenance Self-Verification Form is provided in Appendix F.
FOG inspections include an assessment of the grease control device (GCD) condition where applicable and appropriate, food and grease waste disposal practices, drain screen presence and condition, spill preparedness, and employee training. Businesses also report on GCD maintenance and sewer lateral maintenance. FOG inspection forms are completed digitally via web-based software which produces a report that is emailed to the Responsible Party.
During the inspections, business owners are educated on the City’s FOG Control Program and the BMPs required for proper FOG disposal to prevent spills. The required minimum
CITY OF NATIONAL CITY SEWER SYSTEM MANAGEMENT PLAN PAGE 21 FOG BMPs for FSEs, as well as a FOG fact sheet and employee training template are accessible on the City’s website:
(https://www.nationalcityca.gov/government/engineering-public-works/engineeringdivision/fats-oils-and-grease-fog-control-program) and attached in Appendix F.
Businesses receive a list of corrective actions following the inspection, and inspectors work with business owners until compliance is achieved. Enforcement actions are taken as necessary.
The public are reminded of proper residential FOG disposal on the City’s website (https://www.nationalcityca.gov/government/engineering-public-works/engineeringdivision/fats-oils-and-grease-fog-control-program). Residential FOG BMPs are presented on the website and in Appendix F. Both residents and FSEs are reminded of the importance of private sewer lateral maintenance on the City’s website and in the Sewer Lateral Handout in Appendix F. The City encourages residents to report any potential sewer spill to the City’s Storm Water Hotline at (619) 336-4389.
Lastly, the City began adding residential FOG control messages to its environmental educational calendar in 2015 to help educate residents about how they can reduce FOG discharges to the City’s sanitary sewer system. The calendar is produced every year and distribute to the public. FOG-related messages include methods and resources for proper disposal of grease and common “Do’s” and “Don’ts” for residential grease control. (2) A plan and schedule for the disposal of pipe-blocking substances 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 substances generated within a sanitary sewer system service area;
Residents can store their cooled used cooking oil and grease in a leak-proof container and drop it off at one of EDCO’s 6 buyback locations. Directions and hours can be found on EDCO’s website (www.edco.com). Residential used cooking oil and grease is also accepted at the South Bay Household Hazardous Waste Collection Facility.
The City’s Minimum FOG BMPs for FSEs require that waste cooking grease/oil and FOG from GCD maintenance must be hauled away by an authorized grease hauler and properly disposed of or recycled, and prohibits disposal to the sanitary sewer or storm drain system.
(3) The legal authority to prohibit discharges to the system and identify measures to prevent spills and blockages caused by FOG;
The City possesses the legal authority to prohibit discharges to the sewer system and to identify measures to prevent spills and blockages caused by FOG through the National
CITY OF NATIONAL CITY SEWER SYSTEM MANAGEMENT PLAN PAGE 22 City Municipal Code, Sections 14.06.180, 14.06.190, 14.16.020, 14.16.080, and 14.24.
Excerpts are provided in Appendix C.
(4) Requirements to install grease removal devices (such as traps or interceptors), design standards for the removal devices, maintenance requirements, best management practices requirements, record keeping and reporting requirements; The City’s minimum FOG BMPs (see Appendix F) require that all FSEs within the City have a grease control device (GCD) in the private sanitary sewer system downstream of the kitchen or FOG-generating work area. GCD options include gravity grease interceptors or hydromechanical grease interceptors. City of National City Fats, Oils and Grease Discharge Control Ordinance No. 2024-2531 addresses the installation of grease removal devices (see Appendix C) at new and existing facilities. Design and sizing standards are per 2022 California Plumbing Code, Chapter 10 standards.
All FSEs shall be required, at a minimum, to comply with the following grease control maintenance requirements, when applicable:
• GCDs shall be maintained in efficient operating condition by periodic removal of the full content of the GCD, which includes wastewater, accumulated FOG, floating materials, sludge and solids.
• No FOG that has accumulated in a GCD shall be allowed to pass into any sewer lateral, sewer system, storm drain, or public right-of-way during maintenance activities.
• GCDs shall be fully pumped out and cleaned at a frequency such that the combined FOG and solids accumulation at no time exceeds 25% of the total design hydraulic depth of the GCD. This is to ensure that the minimum hydraulic retention time and required available hydraulic volume is maintained to effectively intercept and retain FOG discharge to the sewer system.
• If a GCD, at any time, contains FOG and solids accumulation that does not meet the requirements described in the previous paragraph, the FSE shall be required to have the GCD serviced immediately such that all fats, oils, grease, sludge, and other materials are completely removed from the GCD. If deemed necessary, the City may also require an increase in the maintenance frequency of the GCD from the current frequency.
• Wastewater, accumulated FOG, floating materials, sludge/solids, and other materials removed from the GCD shall be disposed off-site properly by waste haulers in accordance with federal, state and/or local laws.
CITY OF NATIONAL CITY SEWER SYSTEM MANAGEMENT PLAN PAGE 23 Pre-treatment grease control best management practices (source control BMPs) and maintenance requirements are reviewed with business owners of FSEs during FOG compliance inspections (see Appendix F). Source control BMPs are especially important in limiting the amount of FOG that reaches a GCD. Proper implementation of these ensures that the GCD is functioning effectively and reduces the frequency of GCD maintenance. GCDs are required to have a total grease and solids accumulation of less than 25% by volume in order to be in compliance.
Records of GCD cleaning and maintenance, sewer lateral maintenance, as well as documentation of waste hauling from GCDs and/or grease bins and employee training are required to be kept by FSEs for a minimum of two years as applicable. Requirements for record keeping are discussed during FOG inspections and contact information to report a spill is provided. See Appendix F for details. (5) Authority to inspect grease producing facilities, enforcement authorities, and whether the Enrollee has sufficient staff to inspect and enforce the fats, oils, and grease ordinance;
The City has the authority to inspect grease producing facilities through the National City Municipal Code Section 14.16.080 and 14.24, and enforces any violation of its sewer ordinances per Municipal Code Chapters 1.44 and 1.48. Municipal code excerpts are in Appendix C.
Routine and follow up FSE inspections are conducted by trained City or contract staff.
Escalated enforcement action (e.g. administrative citation) is done by the City’s Code Enforcement.
(6) An identification of sanitary sewer system sections subject to fats, oils, and grease blockages and establishment of a cleaning maintenance schedule for each section; and
The City has identified sections of their sanitary sewer system subject to high levels of FOG. These are shown on the sewer cleaning frequency map (Appendix D). The City has established cleaning and maintenance schedules for these problem sections as noted on the High Frequency Maintenance List are provided in Appendix D. The list of sewer cleaning hotspots has been digitized and is used to help in FOG program planning.
Additionally, FOG inspection program results are tracked in an electronic database and may be compared to the list of priority cleaning locations. (7) Implementation of source control measures for all sources of fats, oils, and grease discharged to the sanitary sewer system for each section identified above.
Source control best management practices (BMPs) remove a significant portion of FOG before the effluent reaches the sanitary sewer system. For FSEs, this helps GCDs perform
CITY OF NATIONAL CITY SEWER SYSTEM MANAGEMENT PLAN PAGE 24 more effectively and also reduces the maintenance frequency for GCDs. As previously discussed, the City conducts FOG inspections at selected FSEs each year, and may also utilize a FOG BMP Self-Verification program where appropriate. All FSEs shall be required, at a minimum, to comply with the following FOG BMPs, when applicable:
• Installation of Drain Screens. Drain screens shall be installed on all drainage pipes in food preparation and utensil cleaning areas.
• Segregation and Collection of Waste Cooking Oil. All waste cooking oil shall be collected and stored properly in recycling receptacles such as barrels or drums.
Such recycling receptacles shall be maintained properly to ensure that they do not leak. Licensed waste haulers or an approved recycling facility must be used to dispose of waste cooking oil. Maintenance logs showing waste hauling-pumping frequency or receipts, or legible copies of receipts from an authorized waste hauler must be kept on site at all times and be accessible for inspection at request of authorized inspector.
• Disposal of Food Waste. All food waste shall be disposed of directly into the trash or garbage, and not in sinks. Double-bagging food wastes that have the potential to leak in trash bins is highly recommended.
• Employee Training. Employees of the FSE shall be trained by ownership/management periodically. Training shall be documented and employee signatures retained indicating each employee’s attendance and understanding of the practices reviewed. Training records shall be available for review at any reasonable time by an inspector or city representative. Training shall include the following subjects:
o Proper implementation of FOG minimum BMPs that employees will be responsible for implementing
o How to “dry wipe” pots, pans, dishware and work areas before washing to remove grease.
o How to properly dispose of food waste and solids in enclosed plastic bags prior to disposal in trash bins or containers to prevent leaking and odors. o The location and use of absorption products to clean under fryer baskets and other locations where grease may be spilled or dripped.
CITY OF NATIONAL CITY SEWER SYSTEM MANAGEMENT PLAN PAGE 25 o How to properly dispose of grease or oils from cooking equipment into a grease receptacle such as a barrel or drum without spilling. • Maintenance of Kitchen Exhaust Filters. Filters shall be cleaned as frequently as necessary to be maintained in good operating condition. The wastewater generated from cleaning the exhaust filter shall be disposed properly. • Kitchen Signage. Best management and waste minimization practices shall be posted conspicuously in the food preparation and dishwashing areas at all times.
The City’s residential BMPs (Appendix F) highlight the source control BMPs that residents should use to minimize FOG. These include: place cooled oil and grease into trash bins or leak-proof containers for disposal, scrape food scraps from dishes into the trash, and use a strainer in the sink to collect excess food particles, among others.
CITY OF NATIONAL CITY SEWER SYSTEM MANAGEMENT PLAN PAGE 26 Chapter 8: System Evaluation, Capacity Assurance, and Capital Improvements
The City’s System Evaluation and Capacity Assurance Plan includes the mandatory procedures and activities, as outlined in the SSSWDR Attachment D, Section 8.
The Plan must include procedures and activities for:
(1) Routine evaluation and assessment of system conditions; (2) Capacity assessment and design criteria;
(3) Prioritization of corrective actions; and
(4) A capital improvement plan.
These requirements are addressed in the following sections.
8.1 System Evaluation and Condition Assessment
The Plan must include procedures to:
(1) Evaluate the sanitary sewer system assets utilizing the best practices and technologies available;
(2) Identify and justify the amount (percentage) of its system for its condition to be assessed each year;
(3) Prioritize the condition assessment of system areas that:
o Hold a high level of environmental consequences if vulnerable to collapse, failure, blockage, capacity issues, or other system deficiencies; o Are located in or within the vicinity of surface waters, steep terrain, high groundwater elevations, and environmentally sensitive areas; o Are within the vicinity of a receiving water with a bacterial-related impairment on the most current Clean Water Act section 303(d) List; (4) Assess the system conditions using visual observations, video surveillance and/or other comparable system inspection methods;
(5) Utilize observations/evidence of system conditions that may contribute to exiting of sewage from the system which can reasonably be expected to discharge into a water of the State;
(6) Maintain documents and recordkeeping of system evaluation and condition assessment inspections and activities; and
The City’s 2008 Sewer System Hydraulic Analysis, 2011 Sewer System Master Plan, and
CITY OF NATIONAL CITY SEWER SYSTEM MANAGEMENT PLAN PAGE 27 2019 Sewer Master Plan Review and CIP Update (all in Appendix G) summarize the City’s approach to the evaluation and condition assessment of its sanitary sewer system. The latter incorporates the critical findings of the 2018 Manhole Condition Assessments conducted by NV5 and the 2009 Sewer Closed-Circuit Television and Condition Assessment Report by others.
The CCTV inspection program serves to regularly document the defects in the collection system and is based on NASSCO PACP standards. The City has CCTV equipment that is regularly used to inspect the collection system. The noted defects are assigned a severity rating and based on the quantity of defects and the noted severity of the defects along a pipe segment, the rehabilitation / replacement method is identified and subsequently prioritized. The findings of the condition assessment program are evaluated against the capacity related projects to avoid potential conflict of the type of improvements needed.
In addition, the City maintains a prioritized list of sewer problem areas. Sections of the sewer system that require more frequent cleaning are identified on High Frequency Maintenance list (Appendix D). City staff also conduct visual inspections of the manholes and pipes as part of the cleaning protocol. Televising of manholes and sewer pipes are done based on these observations, and known problem areas and complaint issues are prioritized for video inspection. Footage taken by City crews is reviewed by sewer staff after collection, and maintenance is done as necessary based on the CCTV footage. (7) Identify system assets vulnerable to direct and indirect impacts of climate change, including but not limited to: sea level rise; flooding and/or erosion due to increased storm volumes, frequency, and/or intensity; wildfires; and increased power disruptions.
The City has completed a climate change asset vulnerability assessment to determine potential impacts of sea level rise, wildfire, increased storm volume, frequency, or intensity leading to higher flows, and higher temperatures. A summary of assessment findings has been included in Appendix G. Additionally, the City has ensured backup generators and bypass procedures are in place for the City’s two pump stations to ensure continued operation in the event of power disruptions or capacity exceedances due to storm or tidal influence. The City has recently inspected most of its sewer pipes with CCTV and visited its sewer manholes to collect updated elevation data, which it is using to update hydraulic modeling and condition assessments. This information will be used to prepare an updated list of proposed capital improvements, which will likely also help address future impacts of climate change. The City is also currently evaluating increasing capacity at the two points where its system connects into the downstream City of San Diego South Metro Interceptor, which takes wastewater to the City of San Diego’s treatment plant.
CITY OF NATIONAL CITY SEWER SYSTEM MANAGEMENT PLAN PAGE 28
8.2 Capacity Assessment and Design Criteria
The Plan must include procedures to identify system components that are experiencing or contributing to spills caused by hydraulic deficiency and/or limited capacity, including procedures to identify the appropriate hydraulic capacity of key system elements for:
(1) Dry-weather peak flow conditions that cause or contributes to spill events; (2) The appropriate design storm(s) or wet weather events that causes or contributes to spill events;
(3) The capacity of key system components; and
(4) Identify the major sources that contribute to the peak flows associated with sewer spills.
The capacity assessment must consider:
(1) Data from existing system condition assessments, system inspections, system audits, spill history, and other available information; (2) Capacity of flood-prone systems subject to increased infiltration and inflow, under normal local and regional storm conditions;
(3) Capacity of systems subject to increased infiltration and inflow due to larger and/or higher-intensity storm events as a result of climate change; (4) Increases of erosive forces in canyons and streams near underground and aboveground system components due to larger and/or higher-intensity storm events;
(5) Capacity of major system elements to accommodate dry weather peak flow conditions, and updated design storm and wet weather events; and (6) Necessary redundancy in pumping and storage capacities.
The City’s 2008 Sewer System Hydraulic Analysis, 2011 Sewer System Master Plan, and 2019 Sewer Master Plan Review and CIP Update (all in Appendix G) summarize the City’s design criteria to ensure sufficient capacity and preserve the estimated lifetime of wastewater infrastructure.
The 2019 Sewer Master Plan Review and CIP Update indicates 155 gravity mains recommended for upsizing by 2038. Replacement diameters for all gravity mains are identified to satisfy the City’s design criteria and accommodate peak flows through 2027.
CITY OF NATIONAL CITY SEWER SYSTEM MANAGEMENT PLAN PAGE 29
8.3 Prioritization of Corrective Action
The findings of the condition assessments and capacity assessments must be used to prioritize corrective actions. Prioritization must consider the severity of the consequences of potential spills.
Overall, the City’s approach to project prioritization is to distinguish between high priority improvements, such as choke points identified in the system that may have an elevated risk, and other, more moderate priority system upgrades. The timing of moderate priority projects may be driven by opportunities to combine these projects with other street improvement projects for cost efficiency. On the other hand, high priority projects are undertaken directly, even when there are not opportunities to combine them with other projects, due to their higher level of importance. It should be noted that Engineering and sewer staff work cooperatively when prioritizing sewer projects and consider capacity data, as well as recent CCTV inspection data, and input from field staff on known problem areas. The City’s Engineering Division in coordination with sewer staff reviews the CIP on an annual basis to ensure the most critical needs are addressed.
In addition to the list of pipes recommended for upsizing based on the hydraulic analysis, the City maintains a prioritized list of sewer problem areas. Sections of the sewer system that require more frequent cleaning are identified on High Frequency Maintenance list (Appendix D). City staff also conduct visual inspections of the manholes and pipes as part of the cleaning protocol. Televising of manholes and sewer pipes are done based on these observations, and known problem areas and complaint issues are prioritized for video inspection. The City has CCTV equipment that is regularly used to inspect the collection system. Footage taken by City crews is reviewed by sewer staff after collection, and maintenance is done as necessary based on the CCTV footage. Again, problem areas identified in the CCTV footage are communicated to the Engineering staff for consideration in the prioritization of sewer system capital improvement projects.
The City’s Engineering Division in coordination with sewer staff reviews the CIP on an annual basis to ensure the most critical needs are addressed. The City contracted a consultant to conduct a hydraulic analysis in 2018-19 of the current wastewater infrastructure. A phased and prioritized Capital Improvement Program was developed based on the results, including recommended immediate projects, short-term projects, 2012 projects, 2017 projects, and 2027 projects. The report also includes recommendations for monitoring and CCTVing to help prioritize projects.
8.4 Capital Improvement Plan
The capital improvement plan must include the following items:
1) Project schedules including completion dates for all portions of the capital improvement program;
CITY OF NATIONAL CITY SEWER SYSTEM MANAGEMENT PLAN PAGE 30 The City’s CIP is presented in the 2011 Sewer System Master Plan and 2019 Sewer Master Plan Review and CIP Update (Appendix G) as previously described. Based on the hydraulic model results presented in the 2019 update, gravity mains were prioritized in a specific year by their inability to satisfy criteria for peak dry weather conditions, and then by their inability to satisfy criteria in peak wet weather conditions. NV5 utilized the NASSCO Pipeline Assessment and Certification Program (PACP) structural observations to further prioritize projects within time-increments. Each phase corresponds to one year with an annual budget of approximately $1.4 Million in construction costs. Phases 1 through 3 are grouped by location and ordered from downstream to upstream. Phases 4 and onward are prioritized based on the estimated depth-to-Diameter. It recommends that future Phases be re-evaluated to determine if conditions have changed that could require reprioritization of the proposed improvements. (2) Internal and external project funding sources for each project; and Funding for these projects is through the Sewer Service Fund. The City allocates funds as needed each year for rehabilitation and replacement of their sewer system. The City’s Engineering Division in coordination with sewer staff reviews the CIP on an annual basis to ensure the most critical needs are addressed.
(3) Joint coordination between operation and maintenance staff, and engineering staff/consultants during planning, design, and construction of capital improvement projects; and Interagency coordination with other impacted utility agencies.
The Engineering Division in coordination with sewer staff reviews the CIP schedule on an annual basis and adjusts if necessary to address the most critical issues. Details on the current CIP phases through 2024 are presented in the supporting map in Appendix H.
The City of National City maintains an open line of communication with other adjacent agencies. These include the County of San Diego, City of Chula Vista, City of San Diego, Port of San Diego, and Naval Base San Diego. Appendix E includes the contact information for these jurisdictions.

Chapter 1.44 - ADMINISTRATIVE CITATIONS
Sections:
1.44.010 - Applicability.
This chapter provides for administrative citations which are in addition to all other legal remedies, criminal or civil, which may be pursued by the city to address any violation of this code and bring about compliance.
The administrative citations process set forth in this chapter may be utilized for compliance efforts to correct noncontinuing or continuing violations of this code, such as those that pertain to licensing, animal control, minor building, plumbing, electrical, mechanical, fire, grading or zoning violations, subject to the provisions of Section 1.44.030D.
Use of this chapter or determination of what constitutes a minor violation shall be at the sole discretion of the city official charged with responsibility for enforcement of the particular code. (Ord. 2242 § 4 (part), 2004; Ord. 2140 § 3 (part), 1998: Ord. 2121 (part), 1996)
1.44.020 - Enforcement officer defined.
For purposes of this chapter, "enforcement officer" means any public officer, city employee or agent of the city with the authority by statute, ordinance or regulation to enforce any provision of this code. (Ord. 2140 § 3 (part), 1998: Ord. 2121 (part), 1996)
1.44.030 - Administrative citation.
Whenever an enforcement officer determines that a violation has occurred, the enforcement officer shall have the authority to issue an administrative citation to any person responsible for the violation.
An administrative citation should provide the following information whenever possible:
The date of the violation;
The identity of the responsible person (owner, tenant, etc.), if available; The address or a definite description of the location where the violation occurred; The section of this code violated and a description of the violation; The amount of the fine for the code violation;
A description of the fine payment process, including a description of the time within which and the place to which the fine shall be paid;
An order prohibiting the continuation or repeated occurrence of the code violation described in the administrative citation;
9. 10.
C.
D.
1. 2.
3. 4.
E.
A.
A description of the administrative citation review process, including the time within which the administrative citation may be contested and directions on how to contest the administrative citation may be obtained;
A statement that the property will be reinspected for compliance, and reinspection fees charged for each reinspection thereafter; and
The name and signature of the citing enforcement officer. The signature of the responsible party may be requested but is not necessary. If refused, the issuing officer may note this fact.
The administrative citation may, but need not, be signed by the person responsible for the violation.
The following procedures will apply in issuing administrative citations for minor code violations of a continuing nature, such as building, plumbing, mechanical, grading, zoning, fire or electrical code:
First, a notice of violation shall be issued allowing a minimum period for voluntary compliance and reinspection at no charge for particular violation(s). Except for building code violations or conditions affecting immediate fire and life safety, the correction period should not be less than ten days nor exceed thirty days. Building code violations shall allow for a thirty-day correction period. If conditions affecting immediate fire or life safety concerns require an immediate shutdown of the premises, or any affected portion if feasible, until correction is made, the citation shall establish a defined period for compliance and reinspection not to exceed thirty days. However, under this circumstance, a separate order to stop work or vacate the premises may be required.
If, upon reinspection, voluntary compliance is not obtained and the condition(s) not satisfactorily corrected, an administrative citation may then be issued which addresses all remaining violations collectively, imposes a fine and establishes a further date for compliance and reinspection. A maximum of fifteen days may be allowed. Reinspection fees are chargeable at this point.
A second or subsequent administrative citation may be issued and a further fine and reinspection fee be imposed if, upon subsequent reinspection, compliance has not been obtained for the particular violation(s) cited under a preceding administrative citation.
If compliance is obtained after an administrative citation is issued and the same or similar violation occurs again, an administrative citation and assessment of the penalty applicable to a second violation may be issued instead.
An administrative citation may be used for code violations that are not of a continuing nature but may be characterized as a single event or occurrence, such as animal control violations, dumping, pollution or littering, without prior issuance of a notice of violation where the issuing officer concluded that enforcement action, rather than a verbal warning, is warranted. (Ord. 2242 § 4 (part), 2004; Ord. 2140 § 3 (part), 1998: Ord. 2121 (part), 1996)
1.44.040 - Method of service.

Upon the filing of a request for a hearing of an administrative citation, a hearing officer shall be chosen by the parties, who shall be neutral and unbiased as to the matter in contention. Experience in the subject area is preferred but not a prerequisite. The city shall maintain a panel of candidates available to serve as hearing officers for the administrative citation hearings. The enforcement officer or other designated city representative and the aggrieved party shall select a hearing officer from the list by alternatively striking names from the panel list, beginning with the aggrieved party. The city and the aggrieved party may share the cost of the hearing officer, or if the aggrieved party chooses, the city will pay the full cost of the hearing officer, if requested by the aggrieved party in writing prior to the hearing.
The hearing should occur not later than sixty days from the time of the request for administrative hearing filed by the aggrieved party, unless waived by the city and the aggrieved party. (Ord. 2277 § 2, 2005: Ord. 2242 § 4 (part), 2004; Ord. 2121 (part), 1996)

The following information and procedures will allow City staff to complete preventative and scheduled maintenance on the Sanitary Sewer System (SSS) to keep the system functioning and prevent the occurrence of spills.
1.1 Spills
According to the Statewide General Waste Discharge Requirements (WSR) for Wastewater Collection Agencies, a Spill is any 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.
Spills include:
• Overflows or releases that reach waters of the US
• Overflows or releases that do NOT reach waters of the US, and • Wastewater backups into buildings on private property that are caused by blockages or flow conditions within the publicly owned portion of a SSS Spills contain high level of pollutants that can contribute to surface and ground water pollution, threaten public health, adversely affect aquatic life and impair recreational use and environment of surface waters.
1.2 Major Sources of Spills
The Statewide General WDR for Wastewater Collection Agencies asserts that many spills are preventable through proactive attention on sanitary sewer system management using the best practices and technologies available to address major causes of spills, including but not limited to:
• Blockages from sources including but not limited to:
• Fats, oils and grease;
• Tree roots;
2 • Rags, wipes and other paper, cloth and plastic products; and • Sediment and debris.
• Sewer system damage and exceedance of sewer system hydraulic capacity from identified system-specific environmental, and climate-change impacts, including but not limited to: Sea level rise impacts including flooding, coastal erosion, seawater intrusion, tidal inundation and submerged lands; • Increased surface water flows due to higher intensity rain events; • Flooding;
• Wildfires and wildfire induced impacts;

1 SECTION 1 PUMP STATION AND PIPELINE OVERVIEW
1.1 Scope of Services
Harris, with sub-consultant, EDI, was retained by the City of National City to prepare Operations and Maintenance Manuals for the City’s two sewer pump stations specific to each site (14th Street Sewer Pump Station (SPS) and the Bay Marina Drive SPS), incorporating SCADA content and calculations as appendices or attachments. The recommendations are based on industry standard guidelines and include manufacturer specific recommendations for operation and maintenance.
Manual will include procedural recommendations for proper operation and maintenance of all equipment including HVAC, mechanical, sensors, electrical equipment and SCADA.
Identification of critical deficiencies with general recommendations on how to address them will be provided under separate cover. It is anticipated that three (3) copies of the draft report, plus pdf copy, will be submitted for City review and comment. A brief bullet-format assessment and recommendations memo will accompany the draft submittal with appendices that will include checklists, photographs, and recommendations pertinent to O&M. Recommendations are to be relevant to electrical and SCADA equipment and settings at each site, with applicable calculations, sketches, and annotated photographs as may be required to communicate assessment and procedural recommendations for proper operation and routine maintenance.
Calculations and recommendations for revising pumping operational parameters are included in the scope of services.
1.2 Work Completed to Date

1. Hydro Ranger Program including Set Points.
2. VFD (variable frequency drive) Program and Set Points.
3. Micro PLC program
1.2.2 Overview of the 14th Street SPS and Pipeline
A summary overview of the site follows:
1. Location: The 14th Street SPS is located at 1400 Tidelands Avenue. Access to the facility is through the Port of San Diego’s General Services and Procurement Department located at 1400 Tidelands Avenue. The SPS consists of a below-grade wet well and an abovegrade single story dry room that houses the electrical equipment. Influent to the pump station consists of discharges from commercial and government tenants, including a dog kennel operator and maritime operations. Maritime operations include buildings and ships at port. The pump station discharges to a manhole located approximately 10 feet north from the SPS. The pump station was upgraded in 2007.
August 2016 1-2 City of National City
H&A: 140.192.02 14th Street SPS O&M Manual
2. Regulatory Deficiencies: The building is deemed by NFPA to be a Hazardous Classified Class 1 facility because it encloses the space above the wet well. Access is not being restricted for confined space per OSHA requirements. The building should be more thoroughly checked for compliance with Division 1 or Division 2 ventilation requirements, and for or electrical conformance NFPA 820 and 70 regulations.
3. The SCADA or remote monitoring equipment was installed but not operational. There is no communication line connection and the system is not powered.
4. Per design and installed, is a control cabinet which house the level controllers (Hydro Ranger) and mini-plc relays etc. It appears that the mini-plc is not working.

This section describes equipment, with a discussion of operation and maintenance procedures.
3.1 Introduction and Summary
The site visits conducted at the 14th Street SPS on December 7, 2015 confirmed the pump station layouts, the mechanical equipment, electrical equipment, instrumentation, and pump controls.
3.2 Pump Station Site
The pump station site should be kept in a neat and orderly appearance.
Operation and Maintenance
Daily
1. Lights working?
2. Noticeable sewage odor?
3. Inspect pump station for any vandalism or damage
Monthly
1. Clean up any trash or debris found on the site.
Annually
1. Building interior/exterior needs painting?
2. Existing walls/fences need repair?
3. Reroofing required?
3.3 Components, Operations and Controls
3.3.1 Wet Well
The 14th Street SPS has a 6-ft diameter wet well and is approximately 22 feet deep. The wet well was lined with Ameron Arrow-Lock PVC in 2007 as part of the pump replacement project. The wet well lining is good condition. See Appendix AppF15 for information on Arrow-Lock.
Operation and Maintenance
Daily
1. Check wet well level. Corresponds to the depth of the ultrasonic? Monthly
1. Remove oil and grease from wet well walls.
2. Remove any grit deposits and rags that may accumulate at the bottom of the wet well.
This may require drawing down the wet well and vacuuming it out. The periodic removal of rags may reduce the frequency of removing them from the pump impeller.
August 2016 3-2 City of National City
H&A: 140.192.02 14th Street SPS O&M Manual
Annually:
1. Inspect wet well for any signs for lining damage or concrete pitting/rebar exposure. At the first signs of lining damage or concrete deterioration, implement plans to repair damage.
2. Inspect all brackets, ladders and pump rails should be inspected for corrosion or damage.
Repair as necessary.
3. Do hatches open and close smoothly? Repair if necessary.
3.3.2 Isolation Valves
The 14th Street SPS uses Dezurik plug valves to isolate equipment throughout the SPS. Catalog cuts are included in Appendices AppF07 to AppF09.
The valves appear to be in good condition and are operated with conventional right-hand-rule of closing when the operator is turned in the clockwise direction. All valves are equipped with handwheel or lever operators. Valves should be operated slowly to minimize the water hammer (surge) effect in the pipeline and other equipment.
Operation and Maintenance
Annually
1. Valves should be exercised to ensure that they will open/close when required.
2. Check valve seat for wear and replace if necessary.
3. Check valve for leakage. Replace packing if necessary.
4. Touch-up paint where necessary.
5. No lubrication is necessary unless the valve is disassembled.
3.3.3 Flow Control Valves
14th Street SPS uses swing check valves with outside lever and spring for flow control. The check valves are manufactured by M&H. Catalog cuts are included in Appendices AppF10 and AppF11.
The check valves are located downstream of the pumps and prevent flow from entering the wet well via the pumps. The valves open automatically when the pumps run and close slowly based on the weight/spring on the lever arm. The speed in which the valves close can be adjusted by the placement of the weight/spring on the lever arm. As with all valves, the valve closing speed should be slow to avoid water hammer occurrences.
Valve wear usually occurs primarily to the clapper hinge-and-shaft assemblies and should be checked for looseness. Valves should be chatter-free, not leaking, and seating properly.
Operation and Maintenance
Daily
1. Observe check valve when pump is running to ensure valve is operational.

3.3.4 Level and Pressure Control Equipment
3.3.4.1 Level Control Equipment
The level control equipment/control panel is designed to control the pump motors in response to the level of the wet well. The main level sensing equipment consists of two ultrasonic level detection/measuring equipment. The ultrasonic level sensors are Siemens Hydroranger 200. The manual of the Siemens Hydroranger 200 is attached in Appendix AppG01.
The ultrasonic level measuring system is composed of an ultrasonic transmitter/receiver placed on top of the wet well and control panel. The depth is measured by the amount of time the sound is emitted then received. The two Siemens Hydroranger 200 are arranged such that one is the lead the other as back-up. The Hydroranger has four relay outputs and one analog output. Relay one is to call the lead pump and relay 2 is to call the lag pump. Relay 3 is not used. Relay 4 is for “ECHO LOSS” meaning failure. Relay 1 is set to start and stop the lead pump at programed levels. If for some reason the level still continue to rise at a certain level, relay 2 is set to start and stop the lag pump. In addition the level sensors are programmed such that the lead and lag pumps alternate at each cycle. Upon failure of the lead level sensor the backup will take over.
The existing program and setting of the sensors is shown in Appendix AppG02.
The analog outputs of the level sensors are fed to an Allen Bradley MicroPLC Model 1100 and the outputs are fed to two VFDs. In addition the programmable logic controller (PLC) monitors the condition of the lead level sensor. The operation and maintenance manual of the PLC is attached in Appendix AppG03.
In addition to the ultrasonic level sensors, two float switches are installed to indicate very low level and very high level of the wet well. The float switches contacts are fed into an intrinsically safe relays and the output of the intrinsically safe relays are fed into the control system. These float switches serves as alarm points. The intrinsically safe relays are Safepak® by Gems Sensor and controls. The operation and maintenance manual of the Safepak is shown in Appendix AppG11.
Additional controls:
The SPS has a three phase power failure monitor. The power failure monitor detects under voltage and phase loss. A good power output (normally close) is use to activate a power failure relay. In normal power this relay is energized thus a loss of power or of any phase, this relay will de-energize. The manual of the power fail monitor is shown on Appendix AppG12.
In the event of this system abnormality, control power to the controller will be disconnected and pump motors cannot operate. In addition, an alarm light will light up indicating loss of power or loss of any phase.

H&A: 140.192.02 14th Street SPS O&M Manual
Since the pump motor and pump for this location are submersible, there is a seal fail detector. The detector checks if moisture has infiltrated the motor which is primarily caused by the failure of the seal between the pump and motor. The seal fail detector has no trademark but a picture is show under pictures. The seal fail will stop any pumping in addition to low level detected by the low level float switch.

H&A: 140.192.02 14th Street SPS O&M Manual
3.3.6 Pump Control Panel/Variable Frequency Drives
The pump control panel consists mainly of a VFD and motor starter. The pump motors are intended to run on VFD but can be switch to motor starter (BY-PASS) via selector switch.
The operation of the pump motor controller is dictated by the level control equipment/control panel.
The Variable Frequency Drives (VFD) used at both sites are Mitsubishi Model F700 VFD’s. The manual of the VFD can be found in Appendix AppG04.
To keep track of the operating hours of the pump/pump motor, a elapse timer is used. The manual of the elapse time is shown in Appendix AppG16.
The updated control diagram of the controller is shown in Appendix AppA05. The control diagram provided by the City shown in Appendix AppA02 is incomplete.
The inputs to the pump control panel are:
1. Low Level – stop pumping operation
2. VFD Call – Start and Stop pumping
3. High Speed – causes the VFD to run a preset speed.
Operation and Maintenance
Daily
1. Record each pump operational hours.
2. Operate pumps separately as duty/standby to see if both are operational.
3. Check if alternative pump setting is on.
4. Check if any circuit breakers were tripped. Determine cause and repair.
Monthly
1. For VFDs - Test audio and visual alarms for PS failure
3.4 Safety Procedures and Precautions
Any time pumps, isolation valves, check valves, or any control panels require work, the appropriate circuit breakers should be disengaged. A lock-out/tag or other lock-out device should be attached to the circuit breaker to alert staff. The tag should remain on the circuit breaker or until all repairs have been completed and pumping station returned to service. The lock-out/tag notification serves to inform all staff that the pump station is non-operational. A sewer by-pass may be required if the repair time is lengthy.
The lock-out/tag for any type of valve repair/maintenance may seem unwarranted, but it will serve to prevent any spills if the pumps are activated for any reason.
Any work on live electrical equipment shall be conducted in accordance with National Fire Protection Agency (NFPA) 70E standards.

3 SECTION 3 PUMP ROOM AND MOTOR/CONTROL ROOM
This section describes equipment, with a discussion of operation and maintenance procedures.
3.1 Introduction and Summary
The site visits conducted at the Bay Marina Drive SPS on December 7, 2015 confirmed the pump station layouts, the mechanical equipment, electrical equipment, instrumentation, and pump controls.
3.2 Pump Station Site
The pump station site should be kept in a neat and orderly appearance.
Operation and Maintenance
Daily
1. Lights working?
2. Noticeable sewage odor?
3. Inspect pump station for any vandalism or damage
Monthly
1. Clean up any trash or debris found on the site.
Annually
1. Building interior/exterior needs painting?
2. Existing walls/fences need repair?
3. Reroofing required?
3.3 Components, Operations and Controls
3.3.1 Wet Well
The Bay Marina SPS has circular two wet wells connected with a 12-inch ductile iron pipe (DIP) at the inverts. The smaller wet well is 6-feet diameter and the larger wet well is 8-feet diameter.
The wet wells do not appear to be lined. The smaller wet well was not replaced in 2007 and is discolored and shows some pitting of the concrete. The galvanized ladder shows signs corrosion pitting and does not extend to the top of the wet well access. The larger wet well appears to be in better condition with discoloration on the wet well walls. The stainless steel brackets holding the ultrasonic transducers and the pump rails appear to be in good condition.
Operation and Maintenance
Daily
1. Check wet well level. Corresponds to the depth of the ultrasonic?
August 2016 3-2 City of National City
H&A: 140.192.02 Bay Marina Drive SPS O&M Manual
Monthly
1. Remove oil and grease from wet well walls.
2. Remove any grit deposits and rags that may accumulate at the bottom of the wet well.
This may require drawing down the wet well and vacuuming it out. The periodic removal of rags may reduce the frequency of removing them from the pump impeller.
Annually:
1. Inspect wet well any signs for concrete pitting and rebar exposure. At the first signs of concrete deterioration, implement plans to repair damage.
2. Inspect all brackets, ladders and pump rails should be inspected for corrosion or damage.
Repair as necessary.
3. Do hatches open and close smoothly? Repair if necessary.
3.3.2 Isolation Valves
The Bay Marina Drive SPS uses Dezurik plug valves to isolate equipment throughout the SPS.
Catalog cuts are included in Appendices AppF07 to AppF09.
The valves appear to be in good condition and are operated with conventional right-hand-rule of closing when the operator is turned in the clockwise direction. All valves are equipped with handwheel or lever operators. Valves should be operated slowly to minimize the water hammer (surge) effect in the pipeline and other equipment.
Operation and Maintenance
Annually
1. Valves should be exercised to ensure that they will open/close when required.
2. Check valve seat for wear and replace if necessary.
3. Check valve for leakage. Replace packing if necessary.
4. Touch-up paint where necessary.
5. No lubrication is necessary unless the valve is disassembled.
3.3.3 Flow Control Valves
The Bay Marina Drive SPS uses swing check valves with outside lever and spring. The Bay Marina Drive SPS check valves are manufactured by Milikin. Catalog cuts are included in Appendices AppF03 to AppF06.
The check valves are located downstream of the pumps and prevent flow from entering the wet well via the pumps. The valves open automatically when the pumps run and close slowly based on the weight/spring on the lever arm. The speed in which the valves close can be adjusted by the placement of the weight/spring on the lever arm. As with all valves, the valve closing speed should be slow to avoid water hammer occurrences.
Valve wear usually occurs primarily to the clapper hinge-and-shaft assemblies and should be checked for looseness. Valves should be chatter-free, not leaking, and seating properly.
August 2016 3-3 City of National City
H&A: 140.192.02 Bay Marina Drive SPS O&M Manual
Operation and Maintenance
Daily
1. Observe check valve when pump is running to ensure valve is operational.

2. Check valve seat and bearing surfaces and replace packing boxes if necessary.
3. Check bolt tightness and hinge pin for wear, replace if necessary.
4. Touchup paint where necessary.
5. No lubrication required unless valve is disassembled.
3.3.4 Level and Pressure Control Equipment
3.3.4.1 Level Control Equipment
The level control equipment/control panel is designed to control the pump motors in response to the level of the wet well. The main level sensing equipment consists of two ultrasonic level detection/measuring equipment. The ultrasonic level sensors are Siemens Hydroranger 200. The manual of the Siemens Hydroranger 200 is attached in Appendix AppG01.
The ultrasonic level measuring system is composed of an ultrasonic transmitter/receiver placed on top of the wet well and control panel. The depth is measured by the amount of time the sound is emitted then received. The two Siemens Hydroranger 200 are arranged such that one is the lead the other as back-up. The Hydroranger has four relay outputs and one analog output. Relay one is to call the lead pump and relay 2 is to call the lag pump. Relay 3 is not used. Relay 4 is for “ECHO LOSS” meaning failure. Relay 1 is set to start and stop the lead pump at programed levels. If for some reason the level still continue to rise at a certain level, relay 2 is set to start and stop the lag pump. In addition the level sensors are programmed such that the lead and lag pumps alternate at each cycle. Upon failure of the lead level sensor the backup will take over.
The existing program and setting of the sensors is shown in Appendix AppG02.
The analog outputs of the level sensors are fed to an Allen Bradley MicroPLC Model 1100 and the outputs are fed to two VFDs. In addition the programmable logic controller (PLC) monitors the condition of the lead level sensor. The operation and maintenance manual of the PLC is attached in Appendix AppG03.
In addition to the ultrasonic level sensors, two float switches are installed to indicate very low level and very high level of the wet well. The float switches contacts are fed into an intrinsically safe relays and the output of the intrinsically safe relays are fed into the control system. These float switches serves as alarm points. The intrinsically safe relays are Safepak® by Gems Sensor and controls. The operation and maintenance manual of the Safepak is shown in Appendix AppG11.
Additional controls:
The SPS has a three phase power failure monitor. The power failure monitor detects under voltage and phase loss. A good power output (normally close) is use to activate a power failure
August 2016 3-4 City of National City
H&A: 140.192.02 Bay Marina Drive SPS O&M Manual
relay. In normal power this relay is energized thus a loss of power or of any phase, this relay will de-energize. The manual of the power fail monitor is shown on Appendix AppG12.
In the event of this system abnormality, control power to the controller will be disconnected and pump motors cannot operate. In addition, an alarm light will light up indicating loss of power or loss of any phase.
The flow is detected by the operation of a check valve in the discharge. A limit switch is incorporated to detect operation of the flow switch. The contact is wired to a time delay relay. If after a period of time the check valve fails to open pump motor will stop in addition to low level detected by the low level float switch.

3.3.4.2 Pressure Control Equipment
There does not appear to be pressure switches on the discharge line of the pumps at this SPS. The purpose of the pressure switch is to disengage the pumps if the check valve doesn’t open or there is a valve closed in the line. The pressure switch is generally set 5 psi higher than the highest pressure in the VFD envelope.
There are no pressure gauges on the discharge line.
Operation and Maintenance
Daily
1. Inspect pressure gage while pumps are running to determine if pressure gage is working.

3.3.6 Pump Control Panel/Variable Frequency Drives
The pump control panel consists mainly of a VFD and motor starter. The pump motors are intended to run on VFD but can be switch to motor starter (BY-PASS) via selector switch.
The operation of the pump motor controller is dictated by the level control equipment/control panel.
The Variable Frequency Drives (VFD) used at both sites are Mitsubishi Model F700 VFD’s. The manual of the VFD can be found in Appendix AppG04.
To keep track of the operating hours of the pump/pump motor, a elapse timer is used. The manual of the elapse time is shown in Appendix AppG16.
The updated control diagram of the controller is shown in Appendix AppA05. The control diagram provided by the City shown in Appendix AppA02 is incomplete.
The inputs to the pump control panel are:
1. Low Level – stop pumping operation
2. VFD Call – Start and Stop pumping
3. High Speed – causes the VFD to run a preset speed.
Operation and Maintenance
Daily
1. Record each pump operational hours.
2. Operate pumps separately as duty/standby to see if both are operational.
3. Check if alternative pump setting is on.
4. Check if any circuit breakers were tripped. Determine cause and repair.
August 2016 3-7 City of National City
H&A: 140.192.02 Bay Marina Drive SPS O&M Manual
Monthly
1. For VFDs - Test audio and visual alarms for PS failure
3.4 Safety Procedures and Precautions
Any time pumps, isolation valves, check valves, or any control panels require work, the appropriate circuit breakers should be disengaged. A lock-out/tag or other lock-out device should be attached to the circuit breaker to alert staff. The tag should remain on the circuit breaker or until all repairs have been completed and pumping station returned to service. The lock-out/tag notification serves to inform all staff that the pump station is non-operational. A sewer by-pass may be required if the repair time is lengthy.
The lock-out/tag for any type of valve repair/maintenance may seem unwarranted, but it will serve to prevent any spills if the pumps are activated for any reason.
Any work on live electrical equipment shall be conducted in accordance with National Fire Protection Agency (NFPA) 70E standards.

6 SECTION 6 INSTRUCTION AND TRAINING
6.1 Confined Space Entry
Confined space is defined by OSHA under 29 CFR Part 1926 Construction. It is defined as a space that
1. Is large enough and so configured that an employee can bodily enter and perform assigned work;
2. Has limited or restricted means for entry or exit; and
3. Is not designed for continuous human occupancy.
A permitted confined space means a confined space that either
1. Contains or has the potential to contain a hazardous atmosphere,
2. Contains a material that has the potential for engulfing an entrant,
3. Has an internal configuration such that an entrant could be trapped or asphyxiated by inwardly converging walls or a floor which slopes downward and tapers to a smaller cross-section; or
4. Contains any other serious safety or health hazard.
All confined spaces should have posted placards identifying the confined space and if it is a permitted confined space. The placards should be placed outside of the designated space.
As defined by OSHA, the wet wells are considered permitted confined space. All entrants into the wet well should be trained in permitted confined space entry.
Confined space training may be obtained from OSHA through their website:
http://www.oshatraining.com/Online-Confined-Spaces-in-Construction-Training-Course.php
6.2 Operator Training

1 SECTION 1: PURPOSE
The City of National City (City) has developed a Spill Emergency Response Plan (SERP) in order to protect public health and safety and the environment in the event of a spill from its system (spill).
This SERP is written in accordance with the following regulations:
• State Water Resources Control Board (SWRCB) Order WQ 2022-0103-DWQ, Statewide General Waste Discharge Requirements General Order for Sanitary Sewer Systems (General Order)
• Regional Water Quality Control Board (RWQCB) Order R9-2007-0005, Waste Discharge Requirements for Sewage Collection Agencies in the San Diego Region The City takes all feasible steps to prevent spills from its collection system. However, if a spill does occur the City makes every effort to contain the spill and mitigate the impacts of it. The City strives to prevent any wastewater from ultimately discharging to a receiving water body. This SERP provides City staff with the necessary direction and guidance to ensure a prompt and effective spill response 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 toxic discharges to waters of the State.
SECTION 2: BACKGROUND
The General Order defines a spill to include 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 the General Order if the exfiltrated sewage remains in the subsurface and does not reach a surface water of the State.
The General Order and RWQCB Order R9-2007-0005 define spill categories as follows:
2 SPILL CATEGORIES
CATEGORY 1 A Category 1 spill is a spill of any volume of sewage from or caused by a sanitary sewer system regulated under this General Order that results in a discharge to:
• A surface water, including a surface water body that contains no flow or volume of water; or
• 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 Enrollee-owned and/or operated lateral that discharges to a surface water is a Category 1 spill.
CATEGORY 2 A Category 2 spill is a spill of 1,000 gallons or greater, from or caused by a sanitary sewer system regulated under this General Order 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 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 this General Order 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 A Category 4 spill is a spill of less than 50 gallons, from or caused by a sanitary sewer system regulated under this General Order 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.
Private Lateral
Sewage Discharge
(PLSDs)
Discharges of untreated or partially treated wastewater resulting from blockages or other problems within a privately owned sewer lateral connected to the enrollee’s sanitary sewer system or from other private sewer assets.
All Spills (Category 1, Category 2, Category 3, Category 4, and PLSDs) are reported to the SWRCB using the online California Integrated Water Quality System (CIWQS). However, regulatory notification and reporting requirements vary based on the type of spill. See Section 4 “spill Notification and Reporting Procedures” for more details.
3 SECTION 3: SPILL RESPONSE PROCEDURES
This section includes the following procedures as required by the General Order, 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 the General Order, State law and regulations, and applicable Regional Water Board Orders; • Ensure that appropriate staff and contractors implement the Spill Emergency Response Plan 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 beneficial uses in the receiving waters; • Implement technologies, practices, equipment, and interagency coordination to expedite spill containment and recovery;
• Implement pre-planned coordination and collaboration with storm drain agencies and other utility agencies/departments prior, during, and after a spill event; • Conduct post-spill assessments of spill response activities; • Document and report spill events as required in this General Order; and • Annually, review and assess effectiveness of the Spill Emergency Response Plan, and update the Plan as needed.
Residents or City staff may report a spill to Public Works. A Work Request is generated in CityWorks based on the report by administrative staff or the spill response crew (if after hours).
All calls or emails to Public Works that indicate a potential sewer discharge or potential storm water discharge are immediately called in to the Public Works Crew Supervisor and wastewater crew. Additionally, email communication of reported discharge issues is sent to all applicable Public Works staff. These procedures prevent any potential delays in initial spill response.
Contact information for applicable personnel is listed below. It should also be noted that the City recently merged the Public Works and Engineering Departments. Therefore, all references are to the Assistant Director of Engineering & Public Works in this SERP. • ASSISTANT DIRECTOR OF ENGINEERING & PUBLIC WORKS

An overview of the City’s spill response protocol is provided as Attachment 1. It is the responsibility of sewer staff to follow these standard response procedures:
A. GENERAL
1. Assess the situation upon arrival and confirm that a spill has occurred. Contact the reporting party indicated on the Work Request if necessary for more information.
2. Follow the City’s Spill Response Flowchart (Attachment 1)
3. Estimate the Spill flow rate and volume using the City’s Methods for Estimating Spill Volume (Attachment 2)
4. Notify the Assistant Director of Engineering & Public Works of all confirmed spills, both public spills and PLSDs, while onsite.
5. Take immediate steps to contain, mitigate, and cleanup the spill using standard procedures and best practices. See sections below for procedural details.
6. Complete the City’s Spill Reporting Form (Attachment 3)
7. Follow the City’s Spill Reporting Flowchart (Attachment 4), which may require notification of other agencies. Regulatory Agency and Adjacent Jurisdiction Contact Information is included in Attachment 5. Should online reporting channels be disabled for any reason, reports may be submitted to the RWQCB using a fax reporting form (Attachment 6).
B. SPILL CONTAINMENT
The primary objective of the spill response is to protect public health and safety and the environment. Every effort must be made to contain the spill and prevent wastewater from contaminating storm drains, drainage channels, or surface waters. This requires staff to complete the following measures during spill containment. These tasks are accomplished through a division of labor and many occur simultaneously.
1. Assess the cause and extent of spill upon arrival.
2. If applicable, evacuate anyone in the path of the flow.
3. Determine the immediate destination of the overflow (e.g. building, street, unpaved surface, storm drain, water body).
4. If suspicious substances or odors are present and may be hazardous, staff should call the Fire Department (Dial 911). Staff should await the direction of the Fire Department before continuing the spill response if containment cannot be continued without harmful exposure or contact.
5 5. Immediately contain the flow:
• Use sand bags and other accessible BMPs to stop the flow and protect storm drains.
• Direct the overflow to a low point if possible.
• Recover the ponded material using the Vactor truck. Additional details on spill cleanup are in Section E.
6. Determine if the spill is public (caused by a failure in the City’s line) or private (caused by conditions in a privately owned lateral). Refer to Section C “spill Cause” for details.
7. Identify and request any additional City staff, contractors, or equipment necessary to stop the flow and contain it. Organize and put into action upon arrival.
8. Control perimeter of overflow site with appropriate barricades, cones, or vehicles to restrict access.
9. Establish traffic control around the spill area and work zone. Contact the National City Police Department for assistance if the spill is in a high traffic area. • Dispatcher (619) 336-4411
• Sewer Pager (619) 896-2671
• Street Pager (619) 896-2766
10. Estimate spill volume (see Attachment 2 “Methods for Estimating Spill Volume”) to include on Spill Reporting Form (Attachment 3). See Section F “Spill Documentation” for details.
11. Take pictures to document the spill. See Section F “Spill Documentation” for details.
C. SPILL CAUSE
Spills may be caused by problems in the City’s line (public) or by conditions in a privately owned lateral (private). Public Spills result from sewer main blockages or sewer main pipe failures. They may also be caused by pump station failures. Private Spills result from private lateral blockages or private lateral pipe failures or grease control device overflows.
The City is entirely responsible for the containment and recovery of Spills caused by issues with public sewer mains or pump stations. The City responds to and notifies the appropriate regulatory agencies of PLSDs (see Section 4), but it is the responsibility of the property owner to mitigate or repair any damages from a private spill. The City will contain the spill if it reaches the public right-of-way and contact a plumbing company if the property owner or manager cannot be reached. The owner will be billed for the cost of the plumber and the City’s operational costs in spill containment.
D. CORRECTION OF SPILL CAUSE
Corrections of spills that result from issues with a public mainline, private lateral, force main leak, or pump station are discussed below. Proper spill containment (as previously described in Section B) applies to all spills.
PUBLIC MAINLINE
• Inspect the flow conditions in the upstream and downstream manholes to determine the location of the blockage.
• Relieve blockage by flushing and rodding.
6 • Divert pipe flows as necessary to allow for inspection by closed circuit television (CCTV). • Bypass the affected manholes for prolonged blockages or pipe collapses. Bypassing can be done by high lining or by the use of temporary pipeline around the affected area to transport water to a parallel main.
• Complete proper spill cleanup (Section E) and spill documentation (Section F).
PRIVATE LATERAL
• Notify property owner or manager of a spill caused by the private lateral. Inform them that they are responsible for corrective actions and must call a licensed contractor immediately.
• If the property owner or manager cannot be reached, the City will contain the spill and attempt to relieve the stoppage following this SERP and then contact a plumbing company if necessary. The owner will be billed for the cost of the plumber and the City’s operational costs in spill containment and correction.
• Complete proper spill documentation (Section F).
FORCE MAIN LEAK
• When a force main leak causes a spill, it will be bypassed while emergency repairs are made to the pipeline. Bypassing can be done by high lining or by the use of temporary pipeline around the affected area to transport water to a parallel main. • Repairs may be done by City staff or by a private contractor depending on the damage to the pipeline, location of leak, volume of overflow and the depth of the pipe. • Complete proper spill cleanup (Section E) and spill documentation (Section F).
PUMP STATION FAILURE
• Each pump station is fitted with an alarm system that alerts the National City dispatchers in the event of:
o Power failure,
o High water level in the wet well, and/or
o Low water level in the wet well,
o Pump failure,
o Either of the pumps not operational.
• City staff or after hours stand-by crews will respond immediately after notification is received. The Public Works staff member or the designated backup will proceed to the lift station to assess the situation and resolve the problem. • If the First Responder requires assistance, he/she will request the appropriate personnel for assistance.
• In the event an emergency bypass procedure is required to prevent a potential spill occurrence at a lift station, City staff will implement the bypass procedure developed specifically for the lift station and described in the City’s Emergency Response Plan specific to the City’s Lift Stations.
7 • If a spill occurred, complete proper spill cleanup (Section E) and spill documentation (Section F).
In the event of a power failure, all sewer staff will report to Public Works for assigned tasks. There are two (2) pump stations on the west side within the City’s sewerage system. The northern station is located at 14th Street and Tidelands Avenue. The southern station is located at 24th Street (Bay Marina Drive) and Tidelands Avenue. Pump stations will be regularly inspected to note the level of wastewater within the wet wells. (It should be noted that the wells have sufficient storage capacity for several days without power.) Additionally, manholes at sea level or below that could fill during a power outage will be periodically checked. If pumping is necessary, the City maintains a generator at the Public Works yard that can be transported to the stations, along with pumping connections.
Note that detailed Operation and Maintenance manuals were prepared for both pump stations in August 2016, and an Emergency Response Plan specific to the City’s Lift Stations was prepared in December 2023.
E. SPILL CLEANUP
Spill sites are thoroughly cleaned as soon as possible. It is important that no residue remain from the spill that could be transported by future rains or could result in human contact. Site restoration is accomplished through the following steps:
1. If spill containment led to spill ponding, vacuum the ponded wastewater and return it to the wastewater system.
2. Wash down all spill areas. Recover the wash water and return it to the wastewater system.
3. Flush, rake, or pick up solids and debris with the Vactor truck and haul away for proper disposal.
4. Disinfect the spill site with disinfectant. Recover the wash water and return it to the wastewater system.
5. Take pictures to document the restoration efforts.
F. SPILL DOCUMENTATION
Applicable records shall be maintained by the City for a minimum of five (5) years and shall be made available for review by the Water Boards during an onsite inspection or through an information request. These include work request forms, spill reporting forms, and any other compliance documentation.
Work Request
A Work Request is generated in CityWorks when a spill is reported to Public Works. A description of the problem and the actions taken by Public Works is completed following the Public Works response. This ensures that sewer incidents are appropriately categorized and directs spill documentation and reporting as necessary. If a sanitary sewer leak, spill or overflow occurred, staff confirm that the Assistant Director of Engineering & Public Works has been notified and are instructed to complete the Spill Reporting Form.
Work Requests are kept on file at the City for at least five (5) years.
Spill Reporting Form
8 The Spill Reporting Form (Attachment 3) follows the outline of incident information as presented in the CIWQS online reporting form. It is organized into sections for background information, spill location, initial observations, spill details, spill response, and notification. Page one is generally complete by the Spill Response field crew, while the second page is completed by supervisory staff and the Assistant Director of Engineering & Public Works. This organization ensures that all information required by CIWQS is recorded in a way that facilitates data entry.
Applicable sections of the spill Reporting Form are completed onsite, including an estimate of the spill volume (see Attachment 2 “Methods for Estimating Spill Volume”). spill reporting forms are submitted to the Assistant Director of Engineering & Public Works immediately following a spill.
The reporting form is reviewed and finalized by the Assistant Director of Engineering & Public Works. Spill Reporting Forms are kept on file at the City for at least five (5) years.
Photographs
Photos shall be taken of spills during spill containment procedures and following spill cleanup.

Details on the requirements for spill entry into CIWQS is provided in Section 4 “Spill Notification and Reporting Procedures”. It should be noted that if CIWQS becomes unavailable for any reason, reporting timelines must still be met and information should be faxed or emailed to the San Diego RWQCB. Attachment 6 (RWQCB Fax Reporting Form) may be used. The City would then enter the data into CIWQS as soon as possible.
G. POSTING
When public health may be at risk, it becomes necessary to post signs warning of contamination in appropriate locations. The San Diego County Department of Environmental Health and Quality (SDCDEHQ) will direct the closure of beach areas and the posting of warning signs. The City will provide assistance to the SDCDEHQ as requested and the Assistant Director of Engineering & Public Works will keep in contact with the SDCDEHQ until warning signs are removed. The Spill Reporting Form (Attachment 3) includes a question to address posting of health warnings.
H. WATER QUALITY MONITORING
As identified on the City’s Spill Response Flowchart (Attachment 1) and on the Spill Reporting Form (Attachment 3) and Flowchart (Attachment 4), sewage spills in which an estimated 50,000 gallons or greater are discharged into a surface water, the Enrollee shall conduct the following water quality sampling no later than 18 hours after the City’s knowledge of a potential discharge to a surface water:
• Collect one water sample, each day of the duration of the spill, at:
o A point in a drainage conveyance system before the drainage conveyance system flow discharges into a receiving water, if sewage discharges to a surface water via a drainage conveyance system; and/or
o Each of the three receiving water sampling locations:
• A point in the receiving water where sewage initially enters the receiving water.
9 • A point in the receiving water, upstream of the point of sewage discharge, to capture ambient conditions absent of sewage discharge impacts.
• A point in the receiving water, downstream of the point of sewage discharge, where the spill material is fully mixed with the receiving water. • If the receiving water has no flow during the duration of the spill, the City must report “No Sampling Due To No Flow” for its receiving water sampling locations.
D-MAX Engineering, Inc. sampling staff are available on-call to respond to spills when requested by the City, in accordance with the procedures on the response flowchart and reporting form. For spills that reach surface waters, monitoring and testing activities will include the following steps:
1. Trained staff will gather representative samples upstream and downstream of any location where spill reached a receiving water body, as well as at the location where the spill entered the water. Sampling will consider spill travel time in the surface water and areas where monitoring may not be possible.
2. Trained staff will collect all samples using proper sampling procedures. This includes documentation of proper maintenance and calibration of monitoring instruments and devices.
3. Log the sample location, time, and water temperature on the chain of custody form.
4. An accredited or certified laboratory will analyze the samples for selected constituents, which may include:
• Ammonia;
• Bacterial Indicators (Total and Fecal Coliform, Enterococcus, and E. coli); • Biochemical Oxygen Demand (BOD);
• Dissolved Oxygen (DO); and
• Total Suspended Solids (TSS)
5. Conduct additional sampling requirements as imposed by the SDCDEH and/or the RWQCB.
Water quality results are required to be uploaded into CIWQS for Category 1 spills in which 50,000 gallons or greater are spilled to surface waters. Water sampling results may be sent to the SDCDEH and the San Diego RWQCB as well as to other regulatory agencies as directed.
10 SECTION 4: SPILL NOTIFICATION AND REPORTING PROCEDURES The City has a responsibility to report and monitor all spills in accordance with the regulatory requirements. The chain of communication for reporting spills is generally summarized below. All spills (Category 1, Category 2, Category 3, Category 4, and PLSDs) are reported to the SWRCB using the online CIWQS. However, regulatory notification and reporting requirements vary based on the type of spill. Additional details are provided in the response and reporting flowcharts in Attachments 1 and 4.
1. Reports of spills are received by the Public Works front desk. A work order is generated using CityWorks and appropriate sewer personnel are dispatched to the site.
2. Sewer staff respond to the spill. Staff notify the Assistant Director of Engineering & Public Works of all confirmed spills, both public spills and PLSDs, while onsite.
3. The sewer crew lead records spill-related information (e.g. spill volume, GPS coordinates, photographs) while onsite and completes the Spill Reporting Form (Attachment 3).
4. The Assistant Director of Engineering & Public Works reports the spill per methods and timelines outlined on the Spill Reporting Flowchart (Attachment 4) and reviews the spill Reporting Form.
5. Regulatory reporting requirements based on the type of discharge are outlined below, as presented in the Spill Reporting Flowchart (Attachment 4).

1 METHODS FOR ESTIMATING SPILL VOLUME
There are a variety of methods to estimate the volume of a sanitary sewer overflow. The three methods that will most likely be used by the City of National City are presented below. The method most appropriate to the sewer overflow in question should be used by the person who is making the estimate. Every effort should be made to make the best possible estimate of the spill volume.
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 100 gallons.
Method 2 --- Measured Volume
The volume of most contained spills can be estimated using this method. The shape, dimensions, and the depth of the spilled wastewater are needed. Shape and dimensions are used to calculate the area of the spill and the depth is used to calculate the volume.
Step 1. Sketch the shape(rectangle, circle, triangle) of the contained sewage.
Step 2. Measure or pace off the dimensions (length, width, diameter, etc).
Step 3. Measure the depth at several locations and calculate an average (i.e. total of all depths measured divided by number of measurements taken).
Step 4. Convert the dimensions, including depth, to feet.
Step 5. Calculate the area using the following formulas:
Rectangle Area = length (feet) x width (feet)
Circle Area = 0.785 x diameter (feet) x diameter (feet) Triangle Area = 0.5 x base (feet) x height (feet)
Step 6. Multiply the area (square feet) times the depth (in feet) to get volume (in cubic feet).
Step 7. Multiply the volume (cubic feet) by 7.5 to convert it to gallons.
Method 3 --- Duration and Flow Rate
Some spills do not pond at the site, but instead may flow into the storm drain system and receiving waterways. For such spills, you need to establish the time duration of the spill and the flow rate. The methods of estimating duration and flow rate are:
Duration: The duration is the amount of time elapsed from the time the spill started to the time the spill stopped.
Start time is sometimes difficult to establish. Here are some approaches:
Local residents can be used to establish start time. Inquire as to their observations.
Spills that occur in rights-of-way are usually observed and reported quickly. Spills that
2 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 the start time.
Changes in flow on a downstream flowmeter can be used to establish the start time.
Typically the daily flow peaks are “cut off” or flattened by the loss of flow. This can be identified by comparing hourly flow data, when available.
Conditions at the spill site change with time. Initially there will be limited deposits of grease and toilet paper. After a few days to a week, the grease forms a light colored residue. After a few weeks to a month the grease turns dark. In both cases the quantity of toilet paper and other materials of sewage origin increase in amount. These changes with time can be used to estimate the start time in the absence of other information.
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.
Flow Rate: The flow rate is the average flow that left the sewer system during the time of the spill. There are three ways to estimate the flow rate:
San Diego Manhole Flow Rate Chart: This chart shows the sewage flowing from a manhole cover for a variety of flow rates. The observations of the field crew are used to select the approximate flow rate from the chart.
Flowmeter: Changes in flows in the downstream flowmeters can be used to estimate the flow rate during the spill.
Estimate based on up-stream connections: Once the location of the spill is known, the number of upstream connections can be determined from the City sewer maps.
Multiply the number of connection by 200 to 250 gallons per day per connection or 8-10 gallons per hour per connection.
Once duration and flow rate have been estimated, the volume of the spill is the product of the duration in hours or days times the flow rate in gallons per hour or gallons per day. That is, Volume of spill = duration (in hours or days) x flow rate (in gallons/hour or gallons/day) Additional Information
The methods presented here have been adapted from the Regional Water Quality Control Board (RWQCB) San Francisco Bay Region requirements for reporting Sanitary Sewer Overflows (SSO) as shown at http://www.waterboards.ca.gov/sanfranciscobay/publications forms/documents/sso%20reporting%20requireme nts%20nov%2011%202004.pdf and the City of San Diego Sewer System Management Plan at https://www.sandiegocounty.gov/content/dam/sdc/dpw/WASTEWATER/SDCSD Sewer System Management Pla n 2020.pdf.
