Introduction
The California State Water Resources Control Board (“SWRCB”) promulgated a waste discharge requirement (“WDR”) permit on May 2, 2006 to regulate sanitary sewer systems. This permit is known as SWRCB Order No. 2006-0003, Statewide General Waste Discharge Requirements for Sanitary Sewer Systems. On July 30, 2013, Attachment A to the Order was promulgated and became effective on September 9, 2013 and is known as Attachment A, SWRCB Order No. WQO 2013-0058-EXEC, amending the Monitoring and Reporting Program for Statewide General Waste Discharge Requirements for Sanitary Sewer Systems (together these documents constitute the “SSS WDR”). Recently, a reissuance of the General Order occurred to update the 16-year-old Order. Order 2022-0103-DWQ will be in effect as of June 5, 2023. This Sewer System Management Plan (SSMP) is intended to update the City’s existing SSMP, in continued compliance with the WDR.
System Overview
The City of Santa Monica, Department of Public Works – Water Resources Division (WRD) provides wastewater collection services over 8.25 square miles in area and servces a resident population of approximately 91,105 (2021). In addition to collecting sewage from parcels within its corporate boundaries, the WRD also collects pass-through flow from the City of Los Angeles, via the Coastal Interceptor System (CIS) and unmetered locations, and conveys (via pumps and/or gravity collection) the sewage to the City of Los Angeles Hyperion Water Reclamation Plant for treatment and disposal.
The WRD is responsible for wastewater collection and pumping in the City, which consists of approximately 154 miles of sewer pipe ranging in diameter from 6-inches to 72-inches, over 2,800 maintenance manholes, two flow-monitoring and sampling stations, and the Moss Avenue Pumping Station (MAPS) that has a pump capacity of 26- million gallons per day (mgd). Sewage also enters Santa Monica from the City of Los Angeles through one metered location and from three unmetered locations and leaves Santa Monica for treatment at the City of Los Angeles Hyperion Water Reclamation Plant through one metered and six unmetered locations. The City of Santa Monica’s 72-inch CIS connection to the City of Los Angeles was designed for the development sunset year of 2090 and has a capacity of approximately 52 mgd. The CIS is owned and maintained by the City of Los Angeles. Presently, the maximum peak instantaneous flow approaches 32.67 mgd and the annual daily averages flow is approximately 14.54 mgd. This flow rate includes all dry weather runoff diversions into the sanitary sewer systems. Long-term build out (e.g., 2020 Regional Housing Needs Assessment) and populaion density increases is evaluated through the City’s WAter and Wastewater Master Plans that is updated every four to five years. Asthe City recognizes the importance of planning for all aspects of future development, water and sewer capacity and demand forecasts are reviewed regularly and updated as needed to keep abreast of changing conditions.
The WRD is also responsible for all water-related assets that support the safe treatment and distribution of potable and recycle water within the City, as well as the collection and conveyance of all sanitary and SEWER SYSTEM MANAGEMENT PLAN 2023

3.2 Agreement with Satellite Agency
The City of Santa Monica does not have a large enough treatment plant to treat all of the wastewater generated in the city. For this reason, there is an agreement with the City of Los Angeles to accept wastewater from Santa Monica. The City of Los Angeles charges Santa Monica based on the amount and strength of flow that is sent to the Hyperion Water Reclamation Plant for final treatment and disposal. These measurements are taken at two outfalls just at the entrance of Santa Monica city limits and right before flow leaves the city.
The City of Los Angeles has tributary areas that combine with sewage from the City of Santa Monica.
These tributaries feed into six different locations around Santa Monica that eventually pass through back into the LA sewer system. The largest amount of pass through comes via the Coastal Interceptor System (CIS) which transports flow from areas upstream of Santa Monica’s service area.

SEWER SYSTEM MANAGEMENT PLAN 2023
WRD SSMP Operations and Maintenance Program Element 4 Page 4-1 ELEMENT 4 - OPERATIONS AND MAINTENANCE (O & M) PROGRAM
SWRCB Requirement:
The SSMP must include those elements listed below that are appropriate and applicable to the Enrollee’s system:
a. Maintain an up-to-date map of the sanitary sewer system, showing all gravity line segments and manholes, pumping facilities, pressure pipes and valves, and applicable storm water conveyance facilities;
b. Describe routine preventive operation and maintenance activities by staff and contractors; including a system for scheduling regular maintenance and cleaning of the sanitary sewer system with more frequent cleaning and maintenance targeted at known problem areas. The Preventative Maintenance (PM) program should have a system to document scheduled and conducted activities, such as work orders;
c. Develop rehabilitation and replacement plan to identify and prioritize system deficiencies and implement short-term and long-term rehabilitation actions to address each deficiency. The program should include regular visual and TV inspections of manholes and sewer pipes, and a system for ranking the condition of sewer pipes and scheduling rehabilitation. Rehabilitation and replacement should focus on sewer pipes that are at risk of collapse or prone to more frequent blockages due to pipe defects. Finally, the rehabilitation and replacement plan should include a capital improvement plan that addresses proper management and protection of the infrastructure assets. The plan shall include a time schedule for implementing the short- and long-term plans plus a schedule for developing the funds needed for the capital improvement plan;
d. Provide training on a regular basis for staff in sanitary sewer system operations, maintenance, and require contractors to be appropriately trained; and e. Provide equipment and replacement part inventories, including identification of critical replacement parts.
4.1 Collection System Maps
The WRD ESRI-GIS database was initially based upon as-built record drawings and was limited to horizontal data. As time progressed, more field information (e.g., elevation and pipe slope) is added to the GIS database. Linear assets older than 75 years usually have limited construction data and the record as-built drawings associated with the assets provide the best engineering data. As the WRD’s asset management plan grows, more information is incorporated including vertical pipe invert and soffit elevations, manhole rim elevations and pipe segment slopes. The database is continuously growing and is also tied to the WRD’s maintenance management system.
SEWER SYSTEM MANAGEMENT PLAN 2023
WRD SSMP Operations and Maintenance Program Element 4 Page 4-2 The City also has limited copies of its older (1960) sewer atlas, which provides some additional data, and can be used to find appropriate as-built drawings. The last update of the sewer atlas occurred in 2000, at which time the City switched to the current GIS system.
As-built drawings are on file at the City’s Department of Public Works – Engineering Division. The Engineering Division is also responsible for the construction of the collection system assets. The City is in the process of incorporating these drawings into the GIS format as funding and resources allows.
Collections system maps are revised as necessary when discrepancies are discovered in the field.
Wastewater crew relay the changes to the supervisor who then passes the information to the Engineering division for revision in the GIS system. Field crews are equipped with hard copies of the maps, tablets for digital access, and access to the Hansen database for work order observations.
4.2 Preventative Maintenance
The elements of the City’s sewer system operation and maintenance (O&M) program include:
x Preventative and corrective maintenance;
x Closed Circuit Television (CCTV) inspections in order to evaluate the condition of the gravity sewers;
x Routine sewer jetting to maintain gravity flow and minimize SSOs; x Replacement and repair of sewers that are in poor condition.
4.2.1 Computer Maintenance Management Systems (CMMS)
To plan and track O&M activities, the City utilizes a computerized maintenance management system (CMMS). The CMMS (Hansen) is capable of tracking equipment and staff by work orders, assisting in the planning and prioritizing of O &M work based on past activity, and maintaining accurate work order and other maintenance documentation used in collection system analysis and reporting. The CMMS is also GIS compatible. The CMMS is the central location for asset history, work orders, and labor hours. The WRD is currently replacing the Hansen CMMS system with a new, modern system provided by MentorAPM that would increase functionality, including tracking vertical assets, asset age, performance, and criticality impacts.
4.2.2 Gravity Sewers
The Wastewater team clean all City-owned sewer pipes between 4-72 inches in diameter. The schedule of cleaning can be every 2 months, 4 months, 6 months, yearly, and every 3-5 years, depending on the condition of the line, operating history, and service area characteristics. The priority is to clean those lines that have a history of blockage or SSOs. Portions of the collection system with repeated SSOs are evaluated for immediate replacement or prioritization as part of the City’s Capital Improvement Program (CIP), depending on the specific conditions present in the line.
SEWER SYSTEM MANAGEMENT PLAN 2023
WRD SSMP Operations and Maintenance Program Element 4 Page 4-3 The Wastewater team utilizes a hydro jetting truck and combo unit trucks to flush and jet sewer lines.
One complete video-capable truck is available for immediate deployment 24 hours per day, and routine main jetting is conducted 5 days a week.
High frequency cleaning occurs in those areas that are known to have many food service establishments (FSEs) that generate FOG and those areas that are known to suffer from persistent root intrusion. These areas are maintained every 2-4 months. Lines that are larger than 15 inches are scheduled to be cleaned at least biennially.
Historical line cleaning results are provided in Table 4-1. Line connections and manholes are inspected at the time of cleaning. Any issues noted during the inspection are scheduled for repair. Either the City or a hired contractor conducts any repairs.

4.2.3 Closed Circuit Television (CCTV) Inspections
The City conducts system-wide routine preventative maintenance activities, including closed circuit television (CCTV) reconnaissance of its collection system, utilizing experienced dedicated O &M staff to ensure efficient and reliable operation of the various components of the sewer system.
One complete video-capable truck is available for immediate deployment 24 hours per day, and routine main jetting is conducted 5 days a week. The priority is to clean those lines that have a history of blockage or SSOs. Portions of the collection system with repeated SSOs are evaluated for immediate replacement or prioritization as part of the City’s CIP, depending on the specific conditions present.
SEWER SYSTEM MANAGEMENT PLAN 2023
WRD SSMP Operations and Maintenance Program Element 4 Page 4-4 The City previously utilized WinCam software for facilitating CCTV activities. Presently, Granite Net will be the new provider for the City’s CCTV program. The City anticipates being able to CCTV every line in the service area within 3-5 years.
4.3 Rehabilitation and Replacement Program
The City has a long-term program to rehabilitate and replace lines in the system that may be deficient.
The program has prioritized portions of the sewer system that have persistent issues, older line segments, and upsizing lines that are 6 inches. This work is included in the City’s CIP process. CIPs are approved biannually. On average, the City replaces 1-2 miles of sewer pipes each year.
4.4 Training
The City encourages, and requires staff, to obtain professional certifications or licenses (e.g., California Water Environment Association). WRD staff receives training on a regular basis in sewer system O&M developments and techniques, and in work safety topics. In addition, many WRD staff maintains various professional certifications through related continuing education or professional participation credits.
Confined space training
4.5 Equipment and Replacement Parts
Critical equipment and replacement part inventories are maintained at the City Maintenance Yard (Yards) Complex, located at 2500 Michigan Avenue in Santa Monica. Mechanical equipment and WRD trucks and support vehicles are fueled, serviced and repaired at the Yards, and many of the administrative functions related to the collection system are also housed in this central location.

These plans extend to sewer mainlines, structures, structures and appurtenances like manholes, lift stations, and service laterals.
5.1.1 General
The City has standards established for new construction, replacement, and renewal regarding any work on the collections system. There is a periodic review of these standards by the Engineering Division. The last update was done in 2021. The most up-to-date version of Standards is available at the City website.
Please see the link below.
Specifications subject to inspection during construction are Construction Standards Institute (CSI) based and are modified as applicable by the Standard Specifications for Public Works Construction (GREENBOOK), latest edition, which is jointly produced by representatives of the American Public Works Association (APWA), the Associated General Contractors of California, the Engineering Contractors Association, the Southern California Contractors Association and BNi Publications, Inc.
Complete versions of the City’s Standards Specifications and Standard Plans are located at the City website. Please click through to:
https://www.santamonica.gov/standard-detail-and-specifications
5.1.2 Moss Avenue Pump Station
MAPS is a sewer pump station owned by the City. MAPS is a critical component of the Coastal Interceptor System (CIS), which moves sewage along the coast from northern Los Angeles, through Santa Monica, and eventually to the Hyperion Treatment Plant. MAPS is the City’s single most critical sewer utility asset as it is in very close proximity to the Santa Monica Pier.
The pump station is equipped with two discharge force mains. To-date, this pump station has predominantly used a single force main for all discharge. Utilizing both force mains, MAPS’ firm capacity (three duty pumps running) has been field measured at 27.6 MGD discharging through a dual force main SEWER SYSTEM MANAGEMENT PLAN 2023
WRD SSMP Design and Performance Element 5 Page 5-2
configuration. The maximum capacity (four pumps running) has been field measured as 36.9 MGD discharging through dual force mains as per the MAPS Evaluation Report 2015.
Detailed information for the MAPS, junction boxes, gauging stations and siphons was obtained from Operations and Maintenance and As-Built Drawings.
5.1.3 Authorized Pipe Materials
The City currently requires polyvinyl chloride pipe as the standard for authorized pipe material.
Specifically, PVC SDR-26 is the type called out for usage in the City. For any pipe lining, cured-in-place-pipe (CIPP) is required.
5.1.4 Private Sewer Systems and Laterals
All private sewer systems and private sewer laterals are required to be design, installed, inspected and accepted per the Green Book and the City Adaptations to the Green Book. Private sewer laterals must also conform to the requirements of the California Plumbing Code.
5.2 Inspection and Testing Criteria
Wastewater construction inspection and testing criteria is based on the Green Book. Standards and specifications are reviewed before any job is put out to bid. Any additional technical requirements will be called out and added to any specific construction project. This criteria applies to new and rehabilitated gravity sewers and new and rehabilitated manholes.
These standards, which are based on Standard Specifications for Public Works Construction, are updated as required by CSMWRD staff and are made available to the public by the Civil Engineering Division upon request so that all engineering contractors and civil engineers are aware of the CSMWRD’s standards for wastewater construction. Presently, City wastewater projects are designed by the Civil Engineering Division within the City, and each project’s contract documents contain all wastewater specification standards, construction notes and details for the project. They are modified to be site-specific on a project-by-project basis. Contract documents are prepared in-house using consultant civil engineers for the plans and technical specifications.
Typically, because of historic development within the City, there are unique construction challenges presented by interfering utilities and confined rights-of-way, which require site or project specific modifications to existing standards. In those cases, the City usually depends upon construction applicants’ private engineers to modify or design a new standard and will review and approve it for site-specific construction.

CSMWRD SSMP Overflow Emergency Response Plan Element 6 Page 6-1 Element 6 Spill Emergency Response Plan
SWRCB Requirements:
a. Each Enrollee shall develop and implement an Spill Emergency Response Plan (SERP) that identifies measures to protect public health and the environment. At a minimum, this plan must include the following:
b. Proper notification procedures so that the primary responders and regulatory agencies are informed of all SSOs in a timely manner;
c. A program to ensure an appropriate response to all overflows; d. Procedures to ensure prompt notification to appropriate regulatory agencies and other potentially affected entities (e.g., health agencies, Regional Water Boards, water suppliers, etc.) of all SSOs that potentially affect public health or reach the waters of the State in accordance with the Monitoring and Reporting Program (MRP). All SSOs shall be reported in accordance with this MRP, the California Water Code, other State Law, and other applicable Regional Water Board WDRs or NPDES permit requirements. The SSMP should identify the officials who will receive immediate notification;
e. Procedures to ensure that appropriate staff and contractor personnel are aware of and follow the Emergency Response Plan and are appropriately trained;
f. Procedures to address emergency operations, such as traffic and crowd control and other necessary response activities; and
g. A program to ensure that all reasonable steps are taken to contain and prevent the discharge of untreated and partially treated wastewater to waters of the United States and to minimize or correct any adverse impact on the environment resulting from the SSOs, including such accelerated or additional monitoring as may be necessary to determine the nature and impact of the discharge.
6.1 Purpose
The City’s SERP serves as a guide for efficiently and appropriately responding to sewer spills. The SERP has directions for staff to follow regarding response, cleanup, and reporting of any sewer spills in the City’s service area.
6.2 Sanitary Sewer Overflow Emergency Response Plan
An SSO is any overflow, spill, release, discharge, or uncontrolled diversion of untreated or partially treated wastewater from a sanitary sewer. SSOs may contain high levels of suspended solids, pathogenic organisms, toxic pollutants, nutrients and oil and grease and can adversely impact human health and the environment. In order to minimize the potential for health and environmental impacts, the City has developed the following plan and standard operation procedure (SOP) for responding to all SSOs.
SEWER SYSTEM MANAGEMENT PLAN 2023
CSMWRD SSMP Overflow Emergency Response Plan Element 6 Page 6-2 SSO Emergency Response Plan:
City water resources and inspection staff have been trained to respond promptly upon receiving notification of an uncontrolled sewage discharge. An SSO can originate from residential structures, commercial facilities, or City related devices, (e.g., broken sewer lines, and/ or manhole covers). Time is of the essence in responding to SSO incidents to control and reduce the potential for impact to the storm drain system and waters of the State.
The SSO plan involves two basic steps.
Step# 1- Upon notification, City Wastewater staff (both Operations and Water Resources Protection Program (WRPP) inspector) responds and identifies the location of the overflow and its characteristics (i.e., apparent source, volume released, extent, and whether it is on private property etc.). They also determine the potential cause of the SSO and the responsible party. This information is recorded on the SSO Response Form. To ensure containment, CSM Wastewater Staff locate the nearest down gradient (down slope) storm drain and determine if the release has, or will, reach this drain. Based on site conditions, the onsite incident manager decides if immediate action or additional staff or equipment is needed to prevent the release from reaching this drain. If the SSO occurred because of a blockage at a main City sewer line, the onsite incident manager will direct CSM Wastewater Staff to immediately contain the discharge by completely berming the storm drain inlet and to clear the blockage. Once the nature and extent of the discharge are known, staff will begin immediate cleanup of discharges caused by a city-owned pipeline; typically by vacuuming the discharge for lawful disposal.
Staff also ensures the release area (all public areas) are cleaned and disinfected after the normal sewer flow is restored and the blockage relieved. If the release has reached the storm drain system, staff will routinely check a couple of storm drain catch basins downstream from the contaminated catch basin to verify how far the release has traveled down the storm drain line.
Depending on the severity of the release, samples may be required to be taken from those catch basins and analyzed for pathogenic organisms. Sampling, if any, conforms to steps taken in the City’s Water Quality Management Plan (WQMP).
If a release from a City-owned main has visibly impacted private property, the onsite staff will photo document all such impacts identified at the time of the release response. Staff also documents the contact information of the property owner and any notes regarding the potential impact in their field notebook. Questions regarding repair costs are directed to the CSM Office of Risk Management at (310) 458-8910.
Step # 2- If the SSO occurred because of a blockage or other problems within a privately owned lateral line resulting in a discharge to the ground surface and /or into the public right-of-way such as City streets, alleys or sidewalks, CSM Wastewater staff will contain and prevent further discharges into the Public Right- of- Way as described in Step #1, above. This is typically done by using a City vacuum truck. CSM staff then contact the subject property owner/manager and direct SEWER SYSTEM MANAGEMENT PLAN 2023
CSMWRD SSMP Overflow Emergency Response Plan Element 6 Page 6-3 them to immediately contact a private plumber to relieve the sewer blockage. In instances where there is no effective response from the property owner or manager to abate the SSO within a reasonable time frame (less than an hour), or at the discretion of the onsite incident manger or the WRPP Inspector, the water service may be temporarily turned off at the subject property after proper notifications are made by calling the CSM Water Division staff and requesting a temporary water service disruption.
Before attempting to turn off the water service, CSM Wastewater Staff will try to contact the property owner or manager. Wastewater Operations Staff will make notification if a WRPP Inspector is unavailable (i.e., after hours, weekends). Notification is made verbally and by posting a large placard in a common area and a door hanger on each unit or residence/ business. Each placard and door hanger has contact information for the CSM and the Los Angeles County DHS Public Health. If possible, door hanger notifications are placed on each tenant’s door depending on access.
Note: The duration, and therefore volume, of the SSO discharge is estimated from when the SSO is first reported to the City, NOT when staff arrives to the site. Staff are required to accurately estimate the volume of the discharge and note how the estimate was derived in their field book.
Photographs of the SSO site are also included in the incident file when damage to private property is known to have occurred.
Other agency contact/reporting include:
- Office of Emergency Services (OES) at (800) 852-7550 to obtain an OES Control#. After business hours including weekends, CSM Wastewater staff makes the notification to OES and provides WRPP inspection staff with the OES Control #.
For logistics planning, staff has determined it typically takes 45-60 minutes for a private plumber to arrive and/ or relieve the sewer blockage on private property. Prior to the arrival of the plumber if the water is not shut down, City staff ensure that the property owner makes all efforts to contain sewer discharges on their property and not allow any discharges onto the public right-of-way.
Any discharge that reaches the public right-of-way will be contained by City staff.
Wastewater Staff monitor the SSO site continuously to make sure the plumbing problem is corrected and sewage at the site has been cleaned up and the release area is disinfected.
Wastewater Operations Staff will disinfect the impacted street and sidewalk (public areas) immediately in contact with the release using chlorine/water solution. Large discharges from private property requiring clean-up will be billed to the property owner for cost recovery of labor and equipment use. Once the sewer blockage is cleared, and the contaminated area cleaned and disinfected, the property owner/manager may call and request the Water Division to turn the water service back on, if needed.
If there is an extensive damage to privately owned properties because of an overflow and release of sewage due to a SSO, depending on the cause, staff will call or advise the property owner to SEWER SYSTEM MANAGEMENT PLAN 2023
CSMWRD SSMP Overflow Emergency Response Plan Element 6 Page 6-4 directly contact LA County Dept. of Health Services (DHS) at 310-665-8484 to evaluate the health hazard and recommend detailed procedures for proper clean-up. Staff will also contact the CSM Office of Risk Management to evaluate any damages if the SSO is caused by blockages or flow conditions within the publicly owned portion of a sanitary sewer system.
It is important to remember that spills into the City storm drain system from SSO’s typically are captured by one of the City diversion BMP projects such as SMURFF, Wilshire Blvd., Montana Ave., Rose Ave., Ashland Ave., Sunset-Canyon and Centinela-Pearl projects and therefore normally do not reach Santa Monica Bay as long as those diversion projects are operational at the time of the incident. Staff will confirm the operational status of the subject BMP project as part of the SSO response procedures.
Once the SSO response incident is concluded, WRPP Inspection Staff forward the required data to the California Integrated Water Quality System (CIWQS) by visiting the agency database at:
http://ciwqs.waterboards.ca.gov and entering on-line the requested information about the SSO.
WRPP Inspection Staff also retain a copy of all completed reports about an SSO incident in a folder designated for SSO records.
SSO Equipment and Training
Typical equipment required for response to an SSO, depending on location and size of the release, includes, but is not limited to, personal protective gear, reporting forms, traffic control devices such as cones or barricades, absorbent materials, sampling equipment, disinfectant solutions, pipe snake, vacuum trucks, backhoe, replacement pipe, and street sweepers.
The City conducts regular training to familiarize staff with health and safety issues, standard response procedures, and regulatory and technological developments. The City also encourages staff to recommend more efficient ways of completing work tasks based on staff field experience.
Moss Avenue Pump Station (MAPS) Emergency Response
CSM staff monitors MAPS through SCADA alarm system during and after hours. Upon discovery or notification of an SSO at the facility, staff would respond to the MAPS to make necessary SSO assessment.
Staff would check the generator, wet well operation, pumps, and force mains. For SSOs that occur because of MAPS or force mains, notifications to proper regulatory agencies and response procedures apply that are discussed as part of this SOP.
Specific procedures include:
Wet Well
x Observe SCADA screen and PLC panel to confirm proper wet well level x If SCADA and PLC not operational, emergency notification to Plant Operator, Supervisor and Senior WRD staff and SCADA technician.
x Call emergency pump contractor for emergency pump/bypass equipment set-up at facility.

7.3 FOG Control Program
The City has determined that a FOG control program is necessary per SSMP requirements. There are approximately 474 food service facilities located within City limits and discharge to City sewers.
Operations and maintenance staff have also noted the tendency for grease buildup in specific sewer lines due to proximity to sources or hydraulic conditions. This section discusses measures the City takes to control FOG.
The City’s FOG control program consists of focused cleaning and maintenance as well as source control.
The following subsections discuss identification and cleaning of grease-prone areas, legal authority to prohibit grease discharge or require a grease removal device, facility inspection, and public outreach.
Water Resources Protection Program and Source Control
The City of Santa Monica Water Resources Protection Program (WRPP) facilitates the FOG Source Control Program and ensures compliance with federal, state, and local regulations for wastewater pretreatment standards prior to discharge into the City’s wastewater collection system. WRPP Staff oversees all industrial and business customers that have the potential to adversely affect the CSM wastewater system by the issuance of Industrial Wastewater permits every year, inspections, and applicable unannounced sampling events for approximately 870 businesses requiring pre-treatment and/or regular monitoring for toxic substances, such as inorganic toxic substances, such as acids & SEWER SYSTEM MANAGEMENT PLAN 2023
WRD SSMP Fats, Oils, And Grease (FOG) Control Program Element 7 Page 7-3 metals, fats from grease and oil producing food-related operations, and other oil and grease producing operations, such as automotive uses, prior to connection and discharge to the wastewater system. For FOG control, there are 474 permittees subject to inspection. For instances of non-compliance with sewer limitations and prohibited discharge standards as specified in the Santa Monica Municipal Code, the WRPP relies on various escalating enforcement actions such as the issuance of Notices of Correction (NOC), Notices of Violation (NOV), administrative citations, and referral to the City Attorney’s office for prosecution. Every permittee inspection is stored in a Hansen 8 computer database as well as a hard copy file. WRPP is also in constant contact with CSM Wastewater staff about any significant findings in the collections system. The WRPP also advises residential customers through outreach information and in tandem with the City’s Household Hazardous Waste Program, the proper disposal methods for toxic materials (such as mercury), waste cooking oil, and other household hazardous waste. In addition, the WRPP has distributed education material on the importance of preventing FOG from entering the sanitary sewer system and brochures on roots and how they adversely affect the wastewater system to the residents of Santa Monica. This information is also distributed to residents at the City of Santa Monica Festival, which is held yearly.
The City also requires the installation of pretreatment devices such as clarifier and grease interceptors for new and remodeled facilities and requires pretreatment devices to be installed in other older facilities that have caused SSOs.
The City also has an annual inspection and random sampling program and keeps records of all permits with proof of regular maintenance of all pretreatment devices by the permit holder.
Wastewater Operations Program
The Wastewater Operations Staff is responsible for the cleaning, monitoring and maintenance of the City’s wastewater collection system. Maintenance consists of four (4) full-time crews, five to six days a week jetting and cleaning the local collection system and the CIS. Wastewater Operations also maintains the City’s Moss Avenue Pumping Station (MAPS), end of line diversions into the sewer system.
The City completed replacing and/or lining 80% of its sewer mains and manholes in 2002. Areas of concern based previous experience are tracked on the City GIS system and are cleaned more frequently.
Together with the CSM Civil Engineering & Architecture Division problem-prone pipelines having both structural and flow capacity issues are prioritized for replacement to minimize the potential for serious SSO incidents.
7.4 GWRD Requirements Response
Requirement (a): An implementation plan and schedule for a public education outreach program that promotes proper disposal of FOG.
Response: The City regulates FOG through WRPP’s Source Control Program and with regular, proactive sewer cleaning. Areas that have a high density of FSEs tend to have higher cleaning frequencies. FSEs are also inspected routinely by WRPP. Finally, public outreach regarding FOG issues is provided for businesses as well as the general public.
SEWER SYSTEM MANAGEMENT PLAN 2023
WRD SSMP Fats, Oils, And Grease (FOG) Control Program Element 7 Page 7-4 Requirement (b): A plan and schedule for the disposal of FOG generated within the sanitary sewer system service area. This may include a list of acceptable disposal facilities and/or additional facilities needed to adequately dispose of FOG generated within a sanitary sewer system service area.
Response: There are grease disposal sites available in Los Angeles County that accept spent grease from nearby commercial disposal companies. The City provides FSEs with a vendor list of California Registered Inedible Kitchen Grease Commercial Transporters. No vendor is recommended or preferred by the City.
Requirement (c):The legal authority to prohibit discharges to the system and identify measures to prevent SSOs and blockages caused by FOG
Response: Santa Monica Municipal Code provides the legal basis for the City’s Source and FOG control program. This is noted in Element 3. More specifically, SMMC 5.20.110 provides requirements for grease disposal and FSE BMPs. SMMC 5.20.080 provides requirements for grease interceptor installation.
Requirement (d): Requirements to install grease removal devices (such as traps or interceptors), design standards for the removal devices, maintenance requirements, BMP requirements, record keeping and reporting requirements.
Response: The City’s WRPP team meets this requirement as described in Requirement (c). Also, WRPP observes FSE BMPs and record keeping during routine inspections.
Requirement (e): Authority to inspect grease producing facilities, enforcement authorities, and whether the Enrollee has sufficient staff to inspect and enforce the FOG ordinance.
Response: WRPP conducts regular inspections of FSEs and is granted authority to inspect and enforce via SMMC 5.20.
Requirement (f): An identification of sanitary sewer system sections subject to FOG blockages and establishment of a cleaning maintenance schedule for each section Response: The City’s Wastewater team prioritizes areas of high FSE concentration and areas where there may be high FOG discharger for more frequent cleaning of connected sewer lines. Wastewater is flexible and will tend to any area that may have become problematic.
Requirement (g): Development and implementation of source control measures for all sources of FOG discharged to the sanitary sewer system for each section identified in (f) above.
Response: Similar to the response to (f), WRPP supports the Wastewater team and follows up on those FSEs that are discharging significant amount of FOG.

Element 8 –Capacity Assurance Plan
SWRCB Requirements:
The Enrollee shall prepare and implement a capital improvement plan (CIP) that will provide hydraulic capacity of key sanitary sewer system elements for dry weather peak flow conditions, as well as the appropriate design storm or wet weather event. At a minimum, the plan must include:
a) Evaluation: Actions needed to evaluate those portions of the sanitary sewer system that are experiencing or contributing to an SSO discharge caused by hydraulic deficiency. The evaluation must provide estimates of peak flows (including flows from SSOs that escape from the system) associated with conditions similar to those causing overflow events, estimates of the capacity of key system components, hydraulic deficiencies (including components of the system with limiting capacity) and the major sources that contribute to the peak flows associated with overflow events;
b) Design Criteria: Where design criteria do not exist or are deficient, undertake the evaluation identified in “a” above to establish appropriate design criteria; and c) Capacity Enhancement Measures: The steps needed to establish a short- and long-term capital improvement plan (CIP) to address identified hydraulic deficiencies including prioritization, alternatives analysis, and schedules. The CIP may include increases in pipe size, I/I reduction programs, increases and redundancy in pumping capacity, and storage facilities. The CIP shall include an implementation schedule and shall identify sources of funding. d) Schedule: The Enrollee shall develop a schedule of completion dates for all portions of the capital improvement program developed in (a-c) above. This schedule shall be reviewed and updated consistent with the SSMP review and update requirements as described in Section D.
14. 8.1.1 System Capacity Evaluation
Evaluation of a sanitary sewer collection system during dry and wet weather conditions involves evaluation of both capacity and general operational issues. The capacity of the system is primarily controlled by population and significant commercial/industrial dischargers. Operational issues that may lead to inadequate level of service system performance include roots, fats, oils and grease. The hydraulic model is an important utility management tool to assist in identifying locations of capacity constraints or velocity concerns that may exist in the existing system or are projected to arise under future dry or weather flows.
Depth of flow in relation to pipe diameter, or depth-to-diameter (d/D) ratio is an element of the City’s existing design criteria and is used herein to identify potential capacity problems within the system, which may result in sewer overflows. A wet weather assessment of the sanitary sewer system is focused on the elimination of wet weather overflows for a particular design storm event. Design storms are primarily defined by their duration and the return period. Duration is the amount of time over which a rain event occurs, where the return period is a measurement of the likelihood a particular event will SEWER SYSTEM MANAGEMENT PLAN 2023
WRD SSMP Capacity Assurance Plan Element 8 Page 8-2
occur. For example, a 5-year storm will theoretically occur once every 5 years. Since the selection of the design storm can have a significant impact on determining the adequacy of system capacity, this design criteria driven level of service element of the Sanitary Sewer Master Plan had careful consideration in this planning effort. Based on discussions with City staff, the design storm selected to be incorporated in the hydraulic model simulation is a 10-year 24-hour event. This design criterion is also used by City of Los Angeles, the regional wastewater conveyance and treatment provider, in the assessment of its sewer system hydraulic capacity analysis programs to contain peak wet weather flows in the sewer design to avoid SSOs.
8.1.2 Existing Conditions Collection System Evaluation
The purpose of a sanitary sewer system is to collect sewer flow from various origins in the City and convey these flows to a designated point of discharge. The maximum and minimum flow rates in any given day can vary, but generally follow some typical daily diurnal patterns for residential and nonresidential customers. The sanitary sewer system should be designed to carry the maximum rate within an acceptable range of velocity without the sewer system backing up during these peak daily flows. In contrast, the sewer system should also have adequate flows and velocity to convey the minimum flow without deposition of suspended solids during the minimum daily time periods, which is typically in the middle of the night. The City’s hydraulic model was developed to effectively simulate the system’s hydraulic behavior at specific time period and analyze its performance under various flow conditions.
The InfoSewer model uses steady-state simulations in its hydraulic analysis calculations for the analysis of utility sewer systems. For a steady-state analysis, all flows are assumed to accumulate in the system and discharge only at the outlets. This means that even if a pipe has a flow beyond its maximum capacity, the flow is still carried downstream including through pumps and force mains so that full/maximum flow conditions are carried through to all affected downstream facilities. The transition between gravity flow and pressurized flow is also ensured by assuming that all flows are transported through each force main, subject to the upstream hydraulic control. The hydraulic evaluation of the City’s existing collection system was performed using the collection system model developed as described earlier and is explained in this section.
The existing system evaluation applies current sewage flows to applicable spatial locations in the system and incorporates current infrastructure configurations and applicable operational strategies, typically associated with pump stations, force mains and diversion structures. A sanitary sewer collection system has basically two main functions: to convey the designed peak discharge and to transport solids so that deposits are kept to a minimum. It is imperative; therefore, that the sanitary sewer has adequate capacity for the peak flow and that it functions at minimum flows without excessive maintenance and odor generation. The existing system scenario takes into consideration the current flows in the existing infrastructure, both under dry and wet weather conditions. The existing scenario incorporates all facilities in the existing sanitary sewer system including gravity mains 10-inch in diameter and greater (and all 8-inch mains directly upstream from 10-inch mains), maintenance holes, lift stations, pumps, force mains, and the outfall station located at SM-1. For the dry weather scenario, sewer flows are loaded to each node in the system based on the summation of account-level tributary sewer flows, as SEWER SYSTEM MANAGEMENT PLAN 2023
WRD SSMP Capacity Assurance Plan Element 8 Page 8-3
derived from water consumption data. To simulate wet weather conditions stemming from infiltration and inflow, a peaking factor (PF) was applied to the dry weather loads at all nodes in the sewer system network. This wet weather PF is calculated as the ratio between the average day flows and the flows that occur on the day out of the year when the highest flows are recorded during a particular wet weather event.
An understanding of the hydraulic condition of the existing system is essential to identify existing system related capacity limitations and to help prioritize recommended system improvements resulting from the ultimate system capacity analysis. The InfoSewer hydraulic model developed as a part of the Sewer Master Plan was used to perform the capacity analysis of the existing collection system. The capacity analysis was performed for various existing flow scenarios including existing average, peak dry weather, and peak wet weather flow scenarios. Improvements are identified based on the evaluation of the existing system during the peak hours of wet weather conditions. The capacity analysis performed herein is consistent with generally accepted methods and is based on the consideration of the depth of flow with respect to the diameter of the pipe. A capacity limited section along a pipeline is identified as a potential capacity related improvement project if the depth to diameter (d/D) ratio exceeds the criteria established to define system performance during the designated wet weather flow scenario conditions. The hydraulic model constructed for this study was used to evaluate performance of the collection system using the criteria for d/D ratio and velocity for gravity pipes, and surcharge depth for maintenance holes. Under existing dry and wet weather flow conditions, a large majority of the City’s sewer collection system pipelines have excess or reserve capacity. The existing hydraulic modeling simulation identified approximately 1 percent of the total sanitary sewer pipeline system had d/D ratios greater than the 0.75 criteria. This finding indicates the City’s sewer system has available capacity in much of the local sewer system.
8.1.3 Background of InfoSewer Software Modeling
The City’s sanitary sewer collection system was modeled using the InfoSewer Version 7.6 software by Innovyze. The InfoSewer software can simulate all aspects of the City’s sanitary sewer collection system through a hydraulic model network. A hydraulic model network is a mathematical representation of the collection system represented by a series of nodes and links. Nodes represent maintenance holes, storage basins, wet wells, junction boxes, and outfalls. Links, as the name implies, represent any hydraulic structure connecting two nodes. Sanitary sewer pipelines, force mains, lift stations, weirs, and gates are all represented by links in this model. During the conduct of hydraulic simulations, the model considers the available storage at these hydraulic elements (through filling and draining) and can simulate unsteady state flow conditions under both open channel and surcharged conditions for varying time periods. Additionally, this model allows simulation of single path and multiple path flow networks, backwater curves, flow reversals, pumps, weirs, siphons, gates, orifices, parallel pipes, and other diversion structures necessary to simulate a sanitary sewer system, such as the City's.

8.2 Design Criteria
The City’s wastewater construction standards are maintained by the Engineering Division of the Public Works Department. These standards are updated as required by City staff and are made available to the public by the Civil Engineering Division upon request so that all engineering contractors and civil engineers are aware of the City’s standards for wastewater construction. Presently, public wastewater projects are designed by the Civil Engineering Division and each project’s contract documents contain all wastewater specification standards, construction notes and details for the project. They are modified to be site-specific on a project-by-project basis. Contract documents are prepared in-house using consultant civil engineers for the plans and technical specifications. Specifications are Construction Standards Institute (CSI) based and are modified as applicable by the Standard Specifications for Public Works Construction (GREENBOOK), latest edition, which is jointly produced by representatives of the American Public Works Association (APWA), the Associated General Contractors of California, the Engineering Contractors Association, the Southern California Contractors Association and BNi Publications, Inc.
8.3 Capital Improvement Goals and Schedules
As part of the City’s collection system CIP, land use and flow modeling are utilized to develop and prioritize five-year and 30-year CIP goals and schedules for consideration and approval by the City Council. The approved CIP projects are implemented as funds become available through a combination of Counciladopted incremental development financing (for increases in land use), Council-approved rate increases (for rate payers), and/or Council-approved increased Wastewater Capital Facility Fees.
The City of Santa Monica pays the City of Los Angeles an Amalgamated Sewerage System Facilities Charge (ASSFC) for upward changes in land use by building permit. Until July 2008, Santa Monica paid Los Angeles by utilizing the Santa Monica Wastewater Capital Facilities Fee collected at the time of permit issuance.
This has left Santa Monica’s CIP program at the same monetary level and funded through a combination of rates collected from rate payers and wastewater capital facility fee at building permit issuance or change of land use.
Currently, the City is on a 100-year sewer line replacement schedule and presently replaces 1 to 2 miles of sewer per year.
8.3.1 CIP Prioritization Criteria
In addition to the individual prioritization of capacity-related projects, other key factors have been integrated in the overall prioritization process. While some of these factors may be somewhat external to the performance of the City’s Wastewater Enterprise, they will influence the timing and potential cost aspects of the program’s implementation and have an influence on the level of community disruption and overall quality of life in Santa Monica. These implementation elements include spatial demand triggers that link to CIP requirements and associated development projects, inclusion of a broader infrastructure management perspective by coordinating the CIP with other projects (e. g., underground utility and paving projects) to minimize community disruption, consideration for cost segregation so that growth pays an SEWER SYSTEM MANAGEMENT PLAN 2023
WRD SSMP Capacity Assurance Plan Element 8 Page 8-5
appropriate share of costs, and an effort to develop a leveled CIP to match the programmed improvements with capital budgeting and ratepayer affordability and acceptance.

SEWER SYSTEM MANAGEMENT PLAN 2023
WRD SSMP Monitoring, Measurement, and Program Modifications Element 9 Page 9-1 Element 9 – Monitoring, Measurement, and Program Modifications SWRCB Waste Discharge Requirement:
The Enrollee shall:
a. Maintain relevant information that can be used to establish and prioritize appropriate SSMP activities;
b. Monitor the implementation and, where appropriate, measure the effectiveness of each element of the SSMP;
c. Assess the success of the PM program;
d. Update program elements, as appropriate, based on monitoring or performance evaluations; and
e. Identify and illustrate SSO trends, including: frequency, location, and volume.
9.1 Performance Measures
Annual performance indicators that the City will use to measure the health of the wastewater collection system and the effectiveness of the SSMP are:
x SSOs: Total number, SSO rate, and number for each cause (e.g., roots, grease or FOG-related blockage, debris, line failure, capacity deficiency, storm flow exceeding design, lift station failure, or other);
x Total volume of SSOs and volume contained and returned to the system; x Total volume and percentage of SSO volume that reached surface water; and x Footage of main lines and percentage of system cleaned annually.
9.2 Monitoring and Measurement
Over the past three years the City’s commitment to asset management and preventative O & M activities has resulted in fewer FOG related SSO incidents. The City regularly tracks and monitors the general effectiveness of preventative maintenance measures through work orders/service requests, number and location of reportable SSO reports, and required annual regulatory reports. Information collected includes cause and location of stoppages; number, cause, location, and volume of SSOs; stoppage response time; number and reason for customer complaints; and type of debris found. The City has selected these certain, specific parameters because they can be documented and compared on an annual basis in a simple format. In addition, experience has shown that these parameters are straightforward, quantitative, and are focused on results.
In addition to the City tracking and monitoring measures, all documented SSO events are reported through the California Integrated Water Quality System (CIWQS) database within the required timeframe.

WRD SSMP Program Audits Element 10 Page 10-1
Element 10 – SSMP Program Audit
SWRCB Waste Discharge Requirement:
As part of the SSMP, the Enrollee shall conduct periodic internal audits, appropriate to the size of the system and the number of SSOs. At a minimum, these audits must occur every two years and a report must be prepared and kept on file. This audit shall focus on evaluating the effectiveness of the SSMP and the Enrollee’s compliance with the SSMP requirements identified in this subsection (D.13), including identification of any deficiencies in the SSMP and steps to correct them.
10.1 SSMP Audits
Internal audits will be conducted by Wastewater Division staff with assistance from WRPP on a biannual (every 2 years) basis to determine the relevance and effectiveness of each element of the SSMP. In addition to reviewing each element of the SSMP, the audits will also include a review of schedule progress for measures implemented to correct any identified deficiencies from the prior version. Based on the findings of the audit process, the SSMP will be updated or modified accordingly. A copy of the audit report checklist and findings report will be retained in the file. The audit checklist was based on the City’s knowledge and size of its system, and the number of FOG related SSO’s. The Audit also incorporates the elements from example self-audits provided by the State Water Resources Control Boards Enforcement Division.

WRD SSMP Communication Program Element 11 Page 11-1
Element 11 – Communication Program
SWRCB Waste Discharge Requirement:
The Enrollee shall communicate on a regular basis with the public on the development, implementation, and performance of its SSMP. The communication system shall provide the public the opportunity to provide input to the Enrollee as the program is developed and implemented.
The Enrollee shall also create a plan of communication with systems that are tributary and/or satellite to the Enrollee’s sanitary sewer system.
11.1 Communication Program Discussion
The CSM maintains active public outreach and communication efforts with all its customers, the publicat-large and surrounding agencies to provide timely information on City projects, improvements, and emergency situations.
Communication outlets range from public meetings and hearings, representation at community groups, to time-critical posting of signage in emergency situations and updates, posting to the CSM public website (https://www.santamonica.gov/) and 24-hour telephone reporting systems. Also, part of the CSM website are links to agenda and minutes from City Council meetings. Additionally, newsletters and brochures are developed and distributed community-wide and staff regularly meets with other area agencies. Informational flyers are often included with customer bills to update the rate payers on system operations, proposed City projects and programs, and the City has public information staff and inter-governmental management staff to maintain routine contact with news and media outlets in a timely manner.
11.2 Communication with Satellite Wastewater Collection Systems The City of Santa Monica communicates regularly with the City of Los Angeles which accepts and treats flow from the City. The City of Santa Monica and other satellite agencies that have their flow treated by Los Angeles attend quarterly contract Cities meetings at which treatment plant, collections system and pretreatment issues are discussed and coordinated.

1 TITLE: TASK #:
JOB TO BE PERFORMED: FREQUENCY: As Required
PROCEDURES
The section of the SSMP provides an overview and summary of the City’s emergency response documents and procedures for sewer overflows.
6.1 Overflow Emergency Response Plan Elements
Pursuant to current regulations, the City has developed and implemented a sanitary sewer overflow emergency response plan (SSO Plan). The SSO Plan identifies measures to protect public health and the environment in the event of an overflow and includes the following elements:
x Proper notification procedures so that the primary responders and regulatory agencies are informed of all SSOs in a timely manner;
x A program to ensure appropriate response to all overflows; x Procedures to ensure prompt notification to appropriate regulatory agencies and other potentially affected entities (e.g. health agencies, regional water boards, water suppliers, etc.) of all SSOs that potentially affect public health or reach the waters of the State. x Procedures to ensure that appropriate staff and contractor personnel are aware of and follow the SSO Plan and are appropriately trained;
x Procedures to address emergency operations, such as traffic and crowd control and other necessary response activities; and
x Procedures to ensure that all reasonable steps are taken to contain untreated wastewater and prevent discharge of untreated wastewater to waters of the United States and minimize or correct any adverse impact on the environment resulting from the SSOs, including such accelerated or additional monitoring as may be necessary to determine the nature and impact of the discharge.
6.2 Sanitary Sewer Overflow Emergency Response Plan
An SSO is any overflow, spill, release, discharge, or uncontrolled diversion of untreated or partially treated wastewater from a sanitary sewer. SSOs may contain high levels of suspended solids, pathogenic organisms, toxic pollutants, nutrients and oil and grease and can adversely impact human health and the City of Santa Monica
Public Works Department – Water Resources Division
Standard Operating Procedures
2 environment. In order to minimize the potential for health and environmental impacts, the City has developed the following plan and standard operation procedure (SOP) for responding to all SSOs.
SSO Emergency Response Plan:
City water resources and inspection staff have been trained to respond promptly upon receiving notification of an uncontrolled sewage discharge. An SSO can originate from residential structures, commercial facilities or City related devices, (e.g. broken sewer lines, and/ or manhole covers). Time is of the essence in responding to SSO incidents in order to control and reduce the potential for impact to the storm drain system and waters of the State.
The City SOP for responding to typical SSOs is available in hardcopy by request. The SSO plan involves two basic steps.
Step# 1- Upon notification, City Wastewater staff (both Operations and Water Resources Protection Program (WRPP) inspector) responds and identifies the location of the overflow and its characteristics (i.e. apparent source, volume released, extent, and whether or not it is on private property etc.). They also determine the potential cause of the SSO and the responsible party. This information is recorded on the SSO Response Form. To ensure containment, CSM Wastewater Staff locate the nearest down gradient (down slope) storm drain and determine if the release has, or will, reach this drain. Based on site conditions, the onsite incident manager decides if immediate action or additional staff or equipment is needed to prevent the release from reaching this drain. If the SSO occurred because of a blockage at a main City sewer line, the onsite incident manager will direct CSM Wastewater Staff to immediately contain the discharge by completely berming the storm drain inlet and to clear the blockage. Once the nature and extent of the discharge are known, staff will begin immediate cleanup of discharges caused by a City-owned pipeline; typically by vacuuming the discharge for lawful disposal.
The information collected on the SSO response form along with any other relevant information is reported by Wastewater Staff to all required outside agencies such as the Office of Emergency Services, LA County Dept. of Health Services, LA Regional Water Quality Control Board, and if applicable, LA Co. Flood Control and City of Los Angeles (see below for more detail).
Staff also ensures the release area (all public areas) are cleaned and disinfected after the normal sewer flow is restored and the blockage relieved. If the release has reached the storm drain system, staff will routinely check a couple of storm drain catch basins downstream from the contaminated catch basin to verify how far the release has traveled down the storm drain line.
Depending on the severity of the release, samples may be required to be taken from those catch basins and analyzed for pathogenic organisms. Sampling, if any, is implemented at the discretion City of Santa Monica
Public Works Department – Water Resources Division
Standard Operating Procedures
3 of the Water Resources Protection Program (WRPP) Inspector on site, and is based on site specific observations. If there is a question about the necessity for sampling, onsite staff confers with the WRPP supervisor on duty. All WRPP Inspector staff have basic sampling equipment available as part of their standard response equipment.
If a release from a City-owned main has visibly impacted private property, the onsite staff will photo document all such impacts identified at the time of the release response. Staff also documents the contact information of the property owner and any notes regarding the potential impact in their field notebook. Questions regarding repair costs are directed to the CSM Office of Risk Management at (310) 458-8910.
Step # 2- If the SSO occurred because of a blockage or other problems within a privately owned lateral line resulting in a discharge to the ground surface and /or into the public right-of-way such as City streets, alleys or side-walks, CSM Wastewater staff will contain and prevent further discharges into the Public Right- of- Way as described in Step #1, above. This is typically done by using a City vacuum truck. CSM staff then contact the subject property owner/manager and direct them to immediately contact a private plumber to relieve the sewer blockage. In instances where there is no effective response from the property owner or manager to abate the SSO within a reasonable time frame (less than an hour), or at the discretion of the onsite incident manger or the WRPP Inspector, the water service may be temporarily turned off at the subject property after proper notifications are made by calling the CSM Water Division staff and requesting a temporary water service disruption.
Before attempting to turn off the water service, CSM Wastewater Staff will try to contact the property owner or manager. Wastewater Operations Staff will make notification if a WRPP Inspector is unavailable (i.e. after hours, weekends). Notification is made verbally and by posting a large placard in a common area and a door hanger on each unit or residence/ business. Each placard and door hanger has contact information for the CSM and the Los Angeles County DHS Public Health. If possible, door hanger notifications are placed on each tenant’s door depending on access.
Note: The duration, and therefore volume, of the SSO discharge is estimated from when the SSO is first reported to the City, NOT when staff arrives to the site. Staff are required to accurately estimate the volume of the discharge and note how the estimate was derived in their field book.
Photographs of the SSO site are also included in the incident file when damage to private property is known to have occurred.
Other agency contact/reporting contacts include:

Standard Operating Procedures
4 - Office of Emergency Services (OES) at (800) 852-7550 to obtain an OES Control#. After business hours including weekends, CSM Wastewater staff makes the notification to OES and provides WRPP inspection staff with the OES Control #.
- LA County Dept. of Health Services at (213) 974-1234 and obtain a ticket #. After business hours including weekends, CSM Wastewater staff contact the agency and provide WRPP inspection staff with the incident ticket#.
- Los Angeles County Department of Health Services (DHS) “Public Health” at 310-665-8484 (8:00am-5:00pm) to respond if sewage has been released at private properties. After business hours including weekends Wastewater Staff call the Los Angeles County Department of Health Services at (213) 974-1234. Los Angeles County DHS will direct clean-up of private property outside surfaces i.e. grass, sidewalk, and patio areas. Wastewater staff does not perform clean up services on private property and therefore the clean-up is the responsibility of the property owner.
- LA Regional Water Quality Control Board at (213) 576-6657. The Contact is Augustine Anijielo who may also be e-mailed at [email protected]. After hours including weekends, Wastewater Staff will notify the agency.
-For sewer discharges into the County of Los Angles Flood Control storm drain system, call 24/7 dispatch – 1-800-675-4357. For Sewer discharges into the City of Los Angeles storm drain system, call 1-800-974-9794. WRPP inspection staff calls in incidents during regular work hours.
Wastewater Staff makes this call during after hours, including weekends. -For a significant spill (i.e. a spill that would bypass treatment and/or enter Santa Monica Bay) the Recreational Waters Program at (626) 430-5360 is also contacted. -For a significant spill into Ashland or Rose Diversions the contact is:
x Jared Deck at (562) 861-0316
x Mike Stephenson: (323) 776-7610
During weekends and after hours: Dispatch: (800) 675-4357 For logistics planning, staff has determined it typically takes 45-60 minutes for a private plumber to arrive and/ or relieve the sewer blockage on private property. Prior to the arrival of the plumber if the water is not shut down, City staff ensure that the property owner makes all efforts to contain sewer discharges on their property and not allow any discharges onto the City of Santa Monica
Public Works Department – Water Resources Division
Standard Operating Procedures
5 Public Right-of- Way. Any discharge that reaches the public right-of-way will be contained by City staff.
Wastewater Staff monitor the SSO site continuously to make sure the plumbing problem is corrected and sewage at the site has been cleaned up and the release area is disinfected.
Wastewater Operations Staff will disinfect the affected City street and sidewalk (public areas) immediately in contact with the release using chlorine/water solution. Large discharges from private property requiring clean-up will be billed to the property owner for cost recovery of labor and equipment use. Once the sewer blockage is cleared, and the contaminated area cleaned and disinfected, the property owner/manager may call and request the Water Division to turn the water service back on, if needed.
If there is an extensive damage to privately owned properties because of an overflow and release of sewage due to a SSO, depending on the cause, staff will call or advise the property owner to contact directly LA County Dept. of Health Services (DHS) at 310-665-8484 to evaluate the health hazard and recommend detailed procedures for proper clean-up. Staff will also contact the CSM Office of Risk Management to evaluate any damages if the SSO is caused by blockages or flow conditions within the publicly owned portion of a sanitary sewer system.
It is important to remember that discharges into the City storm drain system from SSO’s typically are captured by one of the City diversion BMP projects such as SMURFF, Wilshire Blvd., Montana Ave., Rose Ave., Ashland Ave., Sunset-Canyon and Centinela-Pearl projects and therefore normally do not reach Santa Monica Bay as long as those diversion projects are operational at the time of the incident. Staff will confirm the operational status of the subject BMP project as part of the SSO response procedures.
Once the SSO response incident is concluded, WRPP Inspection Staff forward the required data to the California Integrated Water Quality System (CIWQS) by visiting the agency database at:
http://ciwqs.waterboards.ca.gov and entering on-line the requested information about the SSO.
WRPP Inspection Staff also retain a copy of all completed reports about an SSO incident in a folder designated for SSO records.
SSO Equipment and Training
Typical equipment required for response to an SSO, depending on location and size of the release, includes, but is not limited to, personal protective gear, reporting forms, traffic control devices such as cones or barricades, absorbent materials, sampling equipment, disinfectant solutions, pipe snake, vacuum trucks, backhoe, replacement pipe, and street sweepers.

WATER QUALITY MONITORING PLAN
CSMWRD WATER QUALITY MONITORING PLAN Page 1
SECTION 1.0: GENERAL SAMPLING PROCEDURES
This section provides basic procedures for wastewater sampling used for assessing inspection, compliance, and for monitoring the quality of sewage flows in City sewer main lines or accidental discharges to the ocean or other surface water (i.e. SSOs) with a volume of 50,000 gallons or more. The procedures outlined here are based on the U.S. EPA sampling procedures titled: Operating Procedure Number SESDPROC-306-R2. It is important to remember that the monitoring at the City’s outfalls ONLY needs to be implemented if the City’s diversions are not working AND the discharge (single event) exceeds 50,000 gallons. If the diversions are working, all discharges will either be diverted to the Hyperion Treatment Plant or to the City’s SMURRF treatment plant. In these cases, there would be NO discharge to surface waters or the ocean. All water quality sampling will be conducted by Water Resources Protection Programs (WRPP) staff unless after hours or in the event of a City-wide emergency.
In the unlikely event that an SSO or sewer break occurs and the release volume to the storm drain is 50,000 gallons or more and none of the City’s diversion structures are operable, grab samples for water quality will be collected at the appropriate storm drain outfall to receiving waters (i.e. the ocean). There are seven drainage areas in the City that have outfalls at the beach, each with their own City or County operated diversion structure. These drainage area outfalls include:
x Montana Outfall
x Wilshire Outfall
x Santa Monica Pier Outfall,
x Pico-Kenter Outfall,
x Ashland Outfall,
x Rose Outfall, and
x Sunset Canyon Outfall
x Westside Water Quality BMP (filters flows).
A figure showing the location of outfalls within City boundaries is provided in the Element 13 Appendix.
Sampling of subject discharges at the Sunset Canyon or Rose Outfalls will be coordinated with LA County.
1.1 – Standard Sampling Equipment
At a minimum, the following list of equipment should be on hand for typical wastewater sampling activities. Because all sampling is site specific, it is important that knowledge of the site or file
WATER QUALITY MONITORING PLAN
CSMWRD WATER QUALITY MONITORING PLAN Page 2
information be utilized to ensure any necessary specialized equipment is also identified and added to this basic list. Typical sampling equipment includes:

1.2 – Parameters Field Measurements
During sampling, parameters such as temperature, pH, and EC may be measured in the field. Water quality measurements and instrument calibration details will be recorded in field books and in sampling notebooks.
1.2.1 – Field Equipment Calibration
To ensure that data are representative of the actual field conditions, field equipment will be routinely calibrated. For each calibration, the time and date of the procedure, equipment identification number, the calibration procedure and type of standards used will be recorded on field forms and in notebooks accompanying the equipment.
WATER QUALITY MONITORING PLAN
CSMWRD WATER QUALITY MONITORING PLAN Page 3
1.2.2 – Temperature Measurements
Temperature measurements will be made with a mercury-filled thermometer or an electronic thermistor, and all measurements will be recorded in degrees Fahrenheit.
1.2.3 – pH Measurement
The pH measurement will be made as soon as possible after collection of the sample, generally within a few minutes. The pH will be measured by immersing the pH probe into an aliquot of the sample. The pH meter will be calibrated per manufacturer specifications. Two buffer solutions (either pH-4 and pH7, or pH-7 and pH-10, whichever most closely bracket the anticipated range of sample conditions) will be used for instrument calibration.
1.2.4 – Specific Electrical Conductance (EC) Measurement In the event EC parameters are necessary, the EC will be measured by immersing the conductivity probe into an aliquot of the sample. The probes used should automatically compensate for the temperature of the sample. Measurements will be reported in units of micro-Siemens (µS) per square centimeter (equivalent to micromhos or µmhos) at 25 degrees Celsius (77 degrees Fahrenheit).
The EC meter will be calibrated in accordance with the equipment manufacturer’s specifications and as outlined in the instruction manual for the EC meter used. The EC meter will be calibrated with a standard potassium chloride (KCl) solution recommended by the instrument manufacturer.
1.3 – Safety
Proper safety procedures must be observed at all times when collecting wastewater/water samples. It is incumbent on the sampling staff to be aware of potential hazards that may be encountered, and any special safety conditions (e.g. traffic, confined space, etc.) before planning or implementing the field sampling activity. Independent sampling consultants working for the City’s Water Resources Protection Programs (WRPP) must have a site specific Health and Safety Plan (HASP) signed by a Certified Industrial Hygienist or other qualified professional. Sampling conducted by WRPP staff shall be pursuant to all relevant, applicable and most current City health and safety plan (HASP) guidelines.
1.4 – General Sampling Precautions
In order to collect representative and defensible data, field sampling must be conducted with a defined goal in mind (e.g. is the data for compliance, scheduled monitoring, or an enforcement action), and be conducted in an organized and repeatable fashion. Some general sampling precautions are:
WATER QUALITY MONITORING PLAN
CSMWRD WATER QUALITY MONITORING PLAN Page 4
x Store samples in a clean secure location in order to avoid contamination. x Do not overflow bottles that contain preservatives while sampling. x Maintain proper custody procedures at all times (i.e. do not leave samples unattended). x Document all field activities in ink in a field notebook. x To the extent possible, sample collection should progress from the least contaminated location to the most contaminated location in order to minimize the potential for significant crosscontamination from sampling equipment. x If possible, segregate suspected high level contamination samples while storing and transporting from those with potentially lower levels of contamination. x Always use a new pair of clean gloves for each sample location. x Always use new laboratory-cleaned sample bottles.
x Always strictly observe laboratory sample preservative requirements and analytical method holding times.
1.5 – General Sampling Considerations
Because field, operational, or sampling conditions usually vary from one site to the next, the complexity of sampling at a particular site can also be markedly different from another. Key to any sample activity considerations are the specific pollutant limitations for the CSM. These can be found in CSM Municipal Code Section 5.20.040. In addition, the most recent bacterial Total Maximum Daily Load (TMDL) for Santa Monica Bay (receiving waters for our outfalls) is also relevant and applicable.
1.6 – Water Quality Samples
Grab samples will be collected to assess the water quality. The sampler will wear clean chemically resistant gloves as specified in the HASP while collecting the sample. Samples will be collected directly from the sampling device into laboratory-prepared bottles. Gloves will be changed at each individual sample location.
If known, each sampling episode should generally begin with the location having the lowest concentration of target compounds. Successive samples should generally be sampled in sequence of increasing concentration. Field QA/QC samples including equipment blanks, field blanks, trip blanks, and duplicates will be collected as necessary during each sampling event.
If a bladder pump or electric submersible pump is being used to sample, the flow rate will be adjusted to 1) approximately 100 milliliters per minute (mL/min); 2) a rate specifically selected based on discharge flow rates; or 3) as low as possible. This rate will be maintained until the discharge line has been purged and the sample collected.
WATER QUALITY MONITORING PLAN
CSMWRD WATER QUALITY MONITORING PLAN Page 5
All samples will be sent to a State-certified testing laboratory for analysis. Sample analysis will, at minimum, include the following methodologies:
x All outfall samples will be tested for Fecal Coliform by Method SM 9221B, Total Coliform by Method SM 9221E, Enterococcus and Fecal Streptococcus by Method SM 9230B, and in situ pH and field temperature.
x Additional analytes may be added based on knowledge of the discharge source.
1.7 വ Sample Containers and Preservation
Appropriate pre-cleaned sample containers and preservatives for the analyses to be performed will be obtained from the subcontracted analytical laboratory. Appropriate sample containers, volumes, preservation, and holding time requirements are prioritized on Table 1 located in the Element 13 Appendix.
1.8 വ Sample Labeling
Sample containers will be labeled before or immediately after sampling with self-adhesive tags having the following information written in waterproof ink:
x Project number;
x Sample identification number (unique);
x Date and time sample was collected;
x Initials of sample collector; and
x Preservatives used
1.9 വ Quality Control Samples
To evaluate the precision and accuracy of analytical data, quality control samples, such as duplicates and blanks, will be periodically collected and/or prepared (e.g. one per location). These samples will be analyzed for the same analytes using unique (i.e. blind) sample identification number.
1.10 വ Sample Handling, Storage, and Transportation
Efforts will be made to handle, store, and transport supplies and samples safely. Exposure to dust, direct sunlight, high temperature, adverse weather conditions, and possible contamination will be avoided. Immediately following collection, sample bottles will be sealed within a Ziploc bag and placed in a clean chest that contains ice (if cooling is required), and will be transported to the subcontracted laboratory as soon as practical. Samples may only be held in the dedicated sample refrigerator at the WRPP offices.
WATER QUALITY MONITORING PLAN
CSMWRD WATER QUALITY MONITORING PLAN Page 6
2.0 – Field Activity Documentation
The WRPP and Wastewater Division maintain all of its analytical data in an automated data system. In order to maximize the efficiency and accuracy of the data system, all laboratory data is transmitted from the laboratory to the WRRP in an electronic format (WRPP will handle all lab interactions). The responsible party on the COC will receive a copy of the data (including the accompanying COC) in a PDF format. The PDF format provides certainty that the data has not been altered after being generated by the laboratory. Another copy of the data is transmitted directly to the WRPP/Wastewater Division information and technology manager for direct downloading into the data system. It is recommended that if the PDF format is retained, that it be disposed of after three years or pursuant to the most current City document retention guideline. Both the laboratory and the data system will have possession of an approved copy of the data. The current analytical laboratory for the WRRP is the Weck Laboratories Inc., located in the City of Industry, California, 91745, www.wecklabs.com. The laboratory contact is Kim Tu, telephone: (626) 336-2139 and fax: (626) 336-2634, [email protected]. As the contract manager, WRPP is aware of the most current contract laboratory and contact information. If you have any questions, please contact WRPP directly.
Field activities will be documented through field notes, electronic records and/or photographic records.
Field personnel will be responsible for maintaining field logs and more specific records for individual tasks being performed. Information recorded in field logs will include, but may not be limited to, the following:
x Description of field activities;
x Personnel and companies represented at the sample location or source of the discharge; x Field and weather conditions;
x Calibration records;
x Deviations from accepted work or sampling plans, accompanied by a justification for the deviation; and
x Description of equipment problems.
Entries to field logs and task-specific data forms will be made in indelible ink and signed and dated by the personnel making the entry. If changes to entries are necessary, the person making the change will cross out the item to be changed with a single line and initial and date the change. An explanation of the change should be recorded, if necessary.
Photographs of field activities, events of conditions will be supplemented with written records of the subject, date and time of the photographs. All sample location specific information collected electronically by computerized or automated measurement devices will be kept on file at the City’s
WATER QUALITY MONITORING PLAN
CSMWRD WATER QUALITY MONITORING PLAN Page 7
Water Division. Copies of results and records will remain within the Water Division’s project files for a minimum period of three years.
2.1 – Field Data Sheets
A field record will be kept for each day of fieldwork or sampling. A sampling record will be used for each sample location to record the information collected during water quality sampling.
Water quality sampling forms will record the following information:
x Sample identification;
x Duplicate identification, if applicable;
x Date and time sampled;
x Sample location (i.e. outfall name & GIS coordinates); x Owner’s name of site of discharge source;
x Extraordinary circumstances (if any);
x Results of instrument calibration/standardization and field measurements (temperature, pH, EC) and observed relative turbidity;
x Depth from which sample was obtained (if from a diversion structure); x Number and type of sample container(s); and
x Times and volumes corresponding to water quality measurement.
2.2 – Chain-of-Custody Procedures
The methodology described within this section is in general accordance with the procedures described in ASTM Standard D4840-88 (1993) (Practice for Sampling Chain-of-Custody Procedures) (ASTM, 1993b).
After samples have been collected and labeled, they will be maintained under chain-of-custody (COC) procedures. These procedures document the transfer of custody of samples from the field to the laboratory. Each sample sent to the laboratory for analysis will be recorded on a COC record, which will include instructions to the laboratory for analytical services.
Information contained on the triplicate COC record will include:
x Project number;
x Signature of sampler(s);
x Date and time sampled;
x Sample identification;
x Number of sample containers;
x Sample matrix (water);
WATER QUALITY MONITORING PLAN
CSMWRD WATER QUALITY MONITORING PLAN Page 8
x Analyses required;
x Remarks, including preservatives, special conditions, or specific quality control measures; x Turnaround time and person to receive laboratory report; x Method of shipment to the laboratory (i.e. hand delivered, courier, etc.; x Release signature of sampler(s), and signatures of all people assuming custody; and x Condition of samples when received by the laboratory.
Blank spaces on the COC record will be crossed out between the last sample listed and the signatures at the bottom of the sheet.
The field sampler will sign the COC record and will record the time and date at the time of transfer to the laboratory or to an intermediate person. A set of signatures is required for each relinquished/reserved transfer, including transfer within the City Water Division. The original imprint of the COC record will accompany the sample containers. A duplicate copy will be placed in the project file.
If the samples are to be shipped to the laboratory, the original COC record will be sealed inside a plastic Ziploc bag within the ice chest, and the chest will be sealed with custody tape, which has been signed and dated by the last person listed on the chain-of-custody. U.S. Department of Transportation (USDOT) shipping requirements will be followed and the sample shipping receipt will be retained in the project files as part of the permanent COC document. It is required that the shipping company not sign the COC forms as a receiver; instead the laboratory will sign as a receiver when the samples are delivered at the laboratory.
Note: The standard operating procedure is to hand deliver the samples to the lab, or use a lab provided courier.
WATER QUALITY MONITORING PLAN
CSMWRD WATER QUALITY MONITORING PLAN Page 9
3.0 – Equipment Cleaning
Equipment or sampling apparatus that contacts a sample will be decontaminated prior to use unless it is pre-cleaned during manufacture and has remained in its sanitary seal or other original packaging (i.e. disposable equipment). The purpose of decontamination is to minimize the potential for cross contamination during investigation activities.
Bailers, sampling pumps, and other non-dedicated purging or sampling apparatus will be cleaned before and after sampling each location. Factory new and sealed disposable bailers may be used for sampling, but may not be reused. Thermometers, pH electrodes, and EC probes that will be used repeatedly, will be cleaned before and after each sampling and at any time during sampling if the object comes in contact with foreign matter.
Cleaning of reusable equipment (water level probe, submersible pump, etc.) that is not dedicated to a particular sample location will consist of the following:
x Bailers – the inside and outside of bailers will be cleaned in a solution of biodegradable detergent and potable water, followed by a rinse with deionized (DI) water. The bailers may also be steam cleaned, followed by a DI water rinse;
x Pumps – downhole, reusable portions of purge pumps will be steam cleaned on the outside or washed with laboratory-grade detergent followed by a potable water rinse. If the pump does not have a backflow check valve, the inside of the pump and tubing should also be steam cleaned. For a purge pump with a backflow check valve, the interior of the pump and tubing may be cleaned by pumping a laboratory grade detergent and potable water solution through the system followed by a potable water rinse, or by steam cleaning; and x Water Quality Meters – meters will be cleaned by rinsing the portion of the probe that was in contact with the groundwater sample in DI water, and allowing it to air dry.
Sample bottles and bottle caps will be provided by the subcontracted laboratory using standard U.S. EPA approved protocols. Sample bottles and bottle caps will be protected from contact with solvents, dust, or other contamination. Sample bottles will not be reused.

THE ADVANTAGES ARE CLEAR
• Reduction of plumbing repair bills• Prevention of costly property damage, business interruption and/or expensive, unpleasant cleanup due toclogged sewers and overflows • Protection from potential health hazards caused by the accumulation of fats, oils, grease and food particles in yoursewer pipes • Protection for marine life and swimmers from health risks and beach closures due to sewage overflows spilling intoour storm drain system. • Protection for our sanitary sewer system and the
Hyperion Water Treatment Plant.
COMPLIANCE IS MANDATORYAll restaurants, eateries and food preparation facilities musthave a valid Industrial Wastewater Permit.This permit definesdischarge limitations established by the City Ordinance 5.20.40and the U.S. Environmental Protection Agency under theFederal Clean Water Act.Your permit may also require theinstallation of a pretreatment equipment.We encourage business and property owners to take pro-active steps towards preventing fats, oils, and grease fromentering the sewer system by implementing “ Best ManagementPractices” (BMP’s).We regularly monitor wastewater enteringthe sewer and stormdrain systems from your facilities andalert you to any discharges that exceed the limits specified inyour Industrial Wastewater Permit. Our staff will help youidentify the source of the problem, recommend solutions andgive you time to correct the situation. In the event noncompliance continues without resolution, we may be forcedto deny sewer service to your facility.
If you have questions about thepermitting process, pretreatmentsystems, or testing, please don’t hesitate to call us at 310-458-8235.
For water conservation information, please call
310-458-8972 ext 1.
We are pleased to provide youwith the practical and technicalinformation you need to protectyour business, the public health,and our environment.
Use of an in-ground greaseinterceptor prevents grease,oil and fat from reaching Santa Monica Bay.Constant testing of wastewaterdischarges into the sewer andstormdrains helps to ensurethe health of the public and Santa Monica Bay.

WHY NOT?Clean beaches, storm drains, and sewers are just good business.You do everything you can to keep customers comingback. Obviously, sewer overflows and backups are not conducive to repeat business.Often, cooking by-products containing grease are washed intoyour plumbing system through the sinks and floor drains inyour food preparation areas. Over time, the grease clogs yourpipes, sewer lines become blocked, and you have a costly,inconvenient problem to fix,but your problem can becomeeveryone else’s problem, too.Once sewer lines become blocked, wastewater full of fat, oil andgrease are forced up through manhole (utility) covers onto ourstreets and into our storm drain system.The untreated sewage flows through our storm drains to thebeach(see diagram below). Our beaches get poor grades for cleanlinessand sometimes are closed to the public due to significant health risks.The dangerous pathogens found in waste water are not favorable to marine citizens and businesses.Our Water Pollution Prevention Program is designed to protect public health,our environment and your business.
THE SOLUTION...BEST MANAGEMENT PRACTICES Prevent fats, oils and grease from entering your pipes and thesewer system. These simple “Best Management Practices”will enable your restaurant to operate efficiently, safely and cost effectively.• Install an appropriatelysized greasetrap or interceptor inyour place ofbusiness. • Maintain, clean and service your grease trap or
interceptor regularly.
• Filter screens should not be washed on-site. A filter cleaning service must be used, unless you have a grease interceptor.• Do not use prohibited substances such as chlorine, acids and solvents with your grease trap or interceptor, as they may cause serious damage to your pretreatment system and the environment. • Be cautious of chemicals and additives that claim to
dissolve grease (including soaps and detergents). Often,these substances move the grease down your pipes onlyto clog sewer lines elsewhere. • Collect used grease and oil in a proper container that provides secondary containment and recycle. Do not pourgrease into sink, floor drains, or in dumpsters. • Scrape solids and food scraps from cooking surfaces,
plates and utensils into the trash can. Recycle food scrapswhenever possible.The use of garbage disposals is strictly prohibited. • Wash mats and equipment indoors, near kitchen floor
drain, or in janitor’s sink. Remember, untreated water inour storm drainsflow into the ocean. • In the event of a
grease spill in thealley or parking lot,use dry method forspill cleanup suchas kitty litter. Do not hose down spills. • Sweep up food particles, cigarette butts, dirt, sediment and trash from outside areas before rinsing or steam cleaningsurfaces. Use equipment that minimizes water useage andrunoff. Do not use toxic bleaches or detergents which could run into storm drains.
Mop up excess water
and dispose of in
toilet, sink, or
floor drains
connected to the
sanitary sewer.
Sewer lines take waste water to Hyperion Waste Water Treatment Plant Excessive grease contributes to blocked pipes cause sewer overflows intostorm drains leading into the Santa Monica Bay.
Recycle grease,do not pourdown drain. The storm drains take untreated waste water to the bay.
The above diagram shows how an underground grease interceptor prevents fats, oils, and grease from entering the sanitary sewer system.
