EXECUTIVE SUMMARY
On December 6, 2022, the State Water Resources Control Board (SWRCB) adopted Order No.

WQ 2022-0103-DWQ, a General Waste Discharge Requirement (WDR) for all publicly owned sanitary sewer collection systems in California with more than one (1) mile of sewer pipe. This General Order serves as statewide waste discharge requirements and supersedes the previous SWRCB Order No. 2006-0003-DWQ and amendments thereafter. The goal of Order No. WQ 2022-0103-DWQ is to provide a consistent statewide approach for reducing Sanitary Sewer Overflows (SSOs) by requiring to:

1. Comply with federal and state prohibitions of discharge of sewage to waters of the State, including federal waters of the United States;

2. Comply with specifications, and notification, monitoring, reporting and recordkeeping requirements in the General Order that implement the federal Clean Water Act, the California Water Code (Water Code), water quality control plans (including Regional Water Board Basin Plans) and policies;

3. Proactively operate and maintain resilient sanitary sewer systems to prevent spills;

4. Eliminate discharges of sewage to waters of the State through effective implementation of a Sewer System Management Plan;

5. Monitor, track, and analyze spills for ongoing system-specific performance improvements; and

6. Report noncompliance with the General Order per reporting requirements.

The critical component of Order No. WQ 2022-0103-DWQ is the development of a Sewer System Management Plan (SSMP). There are eleven specific elements required in the WDR. The eleven milestones, and the applicable schedule for the City, include:

1. Sewer System Management Plan Goal and Introduction

2. Organization

3. Legal Authority

4. Operation and Maintenance Program

5. Design and Performance Provisions

6. Spill Emergency Response Plan

PROHIBITIONS AND PROVISIONS
The State Water Resources Control Board (SWRCB) Order No. WQ 2022-0103-DWQ mandates that the City of Vernon (City) comply with the following discharge prohibitions and provisions.

I. PROHIBITIONS
To meet the provisions contained in Division 7 of the California Water Code and regulations adopted thereunder, and the provisions of the Clean Water Act and regulations adopted thereunder, the City is required to comply with the following prohibitions:
o Any discharge from a sanitary sewer system that has the potential to discharge to surface waters of the State is prohibited unless it is promptly cleaned up and reported as required.
o Any discharge from a sanitary sewer system, discharged directly or indirectly through a drainage conveyance system or other route, to waters of the State is prohibited. o Any discharge from a sanitary sewer system that creates a nuisance or condition of pollution as defined in Water Code section 13050(m) is prohibited.

In any enforcement action, the Regional Board will consider the efforts of the City to contain, control, clean up and mitigate sewage spills from its collection system in accordance with Section 13327 of the California Water Code. The City will make every effort to contain sewage spilled from its collection systems and to prevent the sewage from entering storm drains and surface water bodies. The City will also make every effort to prevent sewage from discharging from storm drains into flood control channels and open ditches by blocking the storm drainage system and by removing the sewage from the storm drains. The use of the storm drain pipe system to contain the sewage by blocking the drain pipes, and recovering and cleaning up the spilled sewage, in order to prevent the sewage from being discharged to a surface water body is not a violation of the prohibitions listed above.

II. PROVISIONS
As stated in Order No. WQ 2022-0103-DWQ, the City must meet the provisions set forth in Section 6 PROVISIONS (complete descriptions in Appendix A):
o Enforcement Provisions
a. The following enforcement provisions are based on existing federal and state regulations, laws and policies, including the federal Clean Water Act, the state Water Code and the State Water Board Enforcement Policy. i. Enforceability of Clean Water Act and Water Code Violations o The City must comply with all conditions of Order No. WQ 2022- 0103-DWQ. Any noncompliance with Order No. WQ
2022-0103-DWQ constitutes a violation of the California Water Code and a potential violation of the Clean Water Car and is grounds for enforcement action.
ii. Monetary Penalties
City of Vernon
Sewer System Management Plan, Volume I
Update Report
August 2026

o The Water Code provides the State and Regional Water
Boards the authority to pursue formal enforcement actions, including imposing administrative liability and civil monetary penalties, for non-compliance with the requirements of the General Order and violations of the Clean Water Act.
iii. Falsifying or Failure to Report
o The Water Code provides that any person failing or refusing to furnish technical or monitoring program reports, as
required under the General Order, or falsifying any
information provided in the technical or monitoring reports is subject to administrative liability and civil monetary penalties. iv. Severability of General Order
o The provisions of the General Order are severable; if any provision of the Order, or the application of any provision of the Order to any circumstance, is held invalid, the application of such provision to other circumstances and the remainder of the Order shall not be affected thereby.
v. Indirect Discharges
o In the event that a spill enters into a drainage conveyance system, the City shall take all feasible steps to prevent discharge of sewage into waters of the State by blocking or redirecting the flow in the drainage conveyance system, removing the sewage from the drainage conveyance system, and cleaning the system in a manner that does not
inadvertently impact beneficial uses of the receiving water body.
vi. Water Boards’ Considerations for Discretionary Enforcement o Consistent with the State Water Board Enforcement Policy, when considering Water Code section 13327 factors, the State Water Board or a Regional Water Board may consider the
City’s efforts to contain, control, clean up, and mitigate spills. vii. Enforcement Discretion Based on Reporting Compliance o Consistent with the State Water Board Enforcement Policy, City of Vernon

1.1 COMPLIANCE SUMMARY
The City of Vernon was founded in 1905 and is located approximately 5 miles southeast of downtown Los Angeles California. Over its long history, Vernon has been developed as an industrial community. Currently, the City’s owned and operated sanitary sewer collection system is made up of gravity sewers. The gravity system consists of approximately 44 miles of pipe. The City does not own or operate a sewer lift station and/or pressure pipes.

As part of the requirements in Order No. WQ 2022-0103-DWQ, the City has developed a Sewer System Management Plan (SSMP) to incorporate and address the sewer system’s management activities, planning and procedures. The goal of this SSMP is to provide a plan and schedule to properly manage, operate, and maintain all parts of the City’s sanitary sewer collection system, in order to reduce and prevent Sanitary Sewer Overflows (SSO’s), as well as contain and mitigate any SSO’s that do occur. Accordingly, the SSMP will satisfy the requirements of SWRCB Order No.

WQ 2022-0103- DWQ.

The following specific performance indicator goals have also been identified:
o Inspect 33% of all Interceptors annually;
o Clean 50% of all gravity mains annually;
o Conduct a CCTV video inspection of all Fats, Oils and Grease (FOG) hot spots and areas of interest every ten years;
o Conduct internal audits to the SSSMP every three years from the date the last audit was performed. The next internal audit must be completed in 2029. o Conduct updates to the SSMP every six years from the date the last update was City of Vernon

ELEMENT 3. LEGAL AUTHORITY
The City’s Legal Authority addresses the mandatory SSMP element outlined in Attachment D, 3 Legal Authority of SWRCB Order No. WQ 2022-0103-DWQ. This Order is attached as Appendix A.

The City will demonstrate, through sanitary sewer system use ordinances, service agreements, or other legally binding procedures, that it possesses the necessary legal authority to:
o Prevent illicit discharges into its sanitary sewer system from inflow and infiltration (I&I); unauthorized stormwater; chemical dumping; unauthorized debris; roots; fats, oils, and grease; and trash, including rags and other debris that may cause blockages; o Collaborate with storm sewer agencies to coordinate emergency spill responses, ensure access to storm sewer systems during spill events, and prevent unintentional cross connections of sanitary sewer infrastructure to storm sewer infrastructure; o Require that sewer system components and connections be properly designed and constructed;
o Ensure access for maintenance, inspection, and/or repairs for portions of the service lateral owned and/or operated by the City;
o Enforce any violation of its sewer ordinances, service agreements, or other legally binding procedures; and
o Obtain easement accessibility agreements for locations requiring sewer system operations and maintenance, as applicable.

3.1 COMPLIANCE SUMMARY
The City is regulated by several agencies of the United States Government and the State of California, pursuant to the provisions of Federal and State Law. Federal and State Laws (including, but not limited to: 1) Federal Water Pollution Control Act, commonly known as the Clean Water Act (33 U.S.C. Section 1251 et seq); 2) California Porter Cologne Water Quality Act (California Water Code section 13000 et seq.); 3) California Health & Safety Code sections 25100 to 25250; 4) Resource Conservation and Recovery Act of 1976 (42 U.S.C. Section 6901 et seq.); and 5) California Government Code, Sections 54739-54740) grant to the City the authority to regulate and/or prohibit, by the adoption of an ordinance, and by issuance of control mechanisms, the discharge of any waste, directly or indirectly, to the City sewerage facilities. Said authority includes the right to establish limits, conditions, and prohibitions; to establish flow rates or prohibit flows discharged to the City sewerage facilities; to require the development of compliance schedules for the installation of equipment systems and materials by all users; and to take all actions necessary to enforce its authority.

Due to the industrial nature of the City a large number of wastewater generators are classified as Industrial Waste Dischargers by the Sanitation Districts of Los Angeles County (Districts), and thus required to obtain an Industrial Waste Discharge Permit. The Districts are a group of special districts serving the wastewater and solid waste management needs of over five million people and City of Vernon
Sewer System Management Plan, Volume I
Update Report
August 2026

3000 industrial users in Los Angeles County. The Districts were formed under the County Sanitation District Act, passed in 1923 by the California State Legislature. This Act provides for the formation of sewerage authorities based not on political boundaries but rather on the geographic boundaries of the waste disposal problems to be solved.

The Districts adopted a Wastewater Ordinance effective April 1, 1972, as amended on July 1, 1980, July 1, 1983, November 1, 1989, and July 1, 1998 to protect and finance the operation of the Districts' wastewater conveyance, treatment, and disposal facilities. Individual Districts also adopted Connection Fee Ordinances in 1981 (which were amended in 1984, 1990, 1992, and 1997).

Companies that discharge industrial wastewater to the sewerage system are governed by both the Wastewater Ordinance and the Connection Fee Ordinance for the District in which the discharge is located. These legal mechanisms establish the Districts' Industrial Wastewater Discharge Permit, Connection Fee, and Surcharge Programs. The Industrial Wastewater Discharge Permit Program allows for the regulation of industrial wastewater dischargers to protect the public health, environment, and the public sewerage system.

Through a series of Ordinances and Resolutions adopted by the City Council, the Sanitation Districts of the County of Los Angeles, Section 8.32.180 the Municipal Code of the City of Vernon and internally developed Plans and Requirements, the City possesses the necessary legal authority required by Attachment D, 3 Legal Authority of SWRCB Order No. WQ 2022-0103-DWQ:
o The City prevents illicit discharges into its sanitary sewer system through the Municipal Code of the City of Vernon (Section 13.24.070, 13.24.110 and 13.25.070), the Industrial Waste Discharge Permit Requirements of the Sanitation Districts of Los Angeles County (Section 3.2.B.3), and the Wastewater Ordinance of the Sanitation Districts of Los Angeles County (Sections 305 and 406);

To reduce the amount of Fats, Oils and Grease (FOG) discharged to City’s sanitary sewer system, the City has developed a FOG control program. All major industrial users within the City’s service area are identified as part of an initial occupancy inspection by the Department of Public Works.

Accordingly, these customers must complete an Industrial Waste Discharge Permit application with the Sanitation Districts of Los Angeles County (LACSD). This application includes a wastewater sewerage plan showing sewers and associated facilities for the handling of industrial wastewater from the point of origin to the public sewer connection, and identification of all wastewater generation processes. When applicable, additional plans containing spill containment systems, grease interceptors and/or flow measurement systems are included. The City is within LACSD District No.’s 1, 2 and 23. The City requires the installation of a grease interceptor prior to providing service for all new restaurants.

Sand and Grease interceptor inspections for major industrial users are conducted by LACSD staff.

8.1 COMPLIANCE SUMMARY
The City is in the process of developing a System Evaluation, Capacity Assurance, and Capital Improvements Plan which meets the requirements of Attachment D, 8 System Evaluation, Capacity Assurance, and Capital Improvements of SWRCB Order No. 2022-0103-DWQ:
o The City’s 2008 Sewer System Hydraulic Analysis includes wastewater flow projections and a hydraulic analysis of all City-owned gravity mains. The analysis, performed with an H20Map Sewer hydraulic model, includes estimates of peak dry and wet weather flows. The City completed the 2009 Wet Weather Flow Study, which was utilized to calibrate the hydraulic model. The 2008 Sewer System Hydraulic Analysis outlines a Wastewater Capital Improvement Program to mitigate projected deficiencies in the Existing, 5-Year, 10-Year and 20-Year (Planning Horizon) time increment. Sanitary Sewer Overflows were not allowed to exit the system during the hydraulic analysis. o As an alternative to upsizing the capacity of a sewer line, the City may opt to require a reduction in flow of an industrial waste discharger to such an extent that the existing sewer line will have sufficient capacity to meet the City’s design criteria. Per the municipal code, the City has the authority to require a reduction in flow from a business which are violating their LACSD permit;
o The City’s 2008 Sewer System Hydraulic Analysis summarizes the appropriate design and replacement criteria necessary to ensure sufficient capacity, as well as preserve the estimated life-cycle of wastewater infrastructure;
o The City established a short- and long-term Capital Improvement Program (CIP) to address projected hydraulic deficiencies in the 2008 Sewer System Hydraulic Analysis. This includes projected cost estimates, alternatives analysis and project prioritization by 5-Year time increment. The City’s 2008 Sewer System Hydraulic Analysis presents a phased and prioritized Wastewater Capital Improvement Plan (CIP), with funding anticipated through the City’s General Fund;
o Currently, the City is in the process of preparing and implementing an updated Capital Improvement Program (CIP). The City has already established an annual budget for Overflow Emergency Repairs, including hiring an On-Call Contractor to handle all Sewer and Over Flow Emergency Repair services. As part of developing the CIP, the City is planning to do the next round of citywide sewer CCTV inspections within the next 5 years, as part of their ten-year cycle for CCTV inspections. The inspections will help the City develop sewer improvements such as slip lining and/or replacement of damaged sections needed to ensure the sewer design and capacity is efficient and results in fewer overflows and potential hazard to the public.

SANITARY SEWER OVERFLOW RESPONSE PLAN
City of Vernon
Sanitary Sewer Overflow Response Plan
August 2026

SECTION 1: PURPOSE
The purpose of the Sanitary Sewer Overflow Response Plan is to minimize the impact of sanitary sewer overflows (SSO's) to the public and the environment. All sanitary sewer overflows will be responded to in a timely manner to expedite the necessary steps to relieve the overflow. Relieving the sewage blockage and spill containment will be the highest priority of the City of Vernon (City), taking into consideration public health and safety concerns. This response plan is a guideline for the standard operating procedures in the event of a sanitary sewer overflow. The response plan will be reviewed periodically to ensure that all corrective measures are being taken.

As the primary first responders, the Department of Public Works will respond to a potential sanitary sewer overflow (SSO) site and will enlist the assistance of the Department of Health & Environment Control. Should the SSO involve hazardous material, the Fire Department will implement the necessary Standard Operating Procedure for the handling of hazardous materials.

If there is no hazardous material involved, the Public Works crew will proceed with containment, clean-up, and restoration.

SECTION 2: SPILL RESPONSE
Once notification is received, the City's Public Works crew will respond to the spill site with the proper spill response and safety equipment. After normal business hours, the City's Public Works stand-by crew will respond. The Street Supervisor, or senior crew member, will assess the problem and assign the crew job duties to eliminate the overflow if originating from a City-owned facility. If the overflow originates from private infrastructure, the Street Supervisor or senior crew member will instruct the appropriate private wastewater generator to eliminate the overflow. The Street Supervisor or senior crew member will notify the Public Works Director as soon as reasonably possible, but not to exceed 48 hours whether the problem occurs during, or after, normal business hours.

SECTION 3: CONTAINMENT
Containment is a top priority for the City. The Public Works crew will make any reasonable effort to keep the SSO as small of an area as possible. It is preferred that the crew keeps the SSO out of storm drains. To make sure the SSO is contained, the Public Works crew will use the following methods:
o Use sandbags, soil or other containment devices/material to keep the overflow from reaching a storm drain.
o Should the overflow take place in an area not normally accessible to the public, the Public Works crew will use any reasonable means to contain the flow in that area for recovery. o Should the flow be too much to be contained on the street, the Public Works crew will attempt to contain the spill in the storm drain and recover it from that point. o Contracted Agency – Depending on SSO
City of Vernon
Sanitary Sewer Overflow Response Plan
August 2026

SECTION 4: EMERGENCY TRAFFIC CONTROL
If the spill occurs in a roadway, traffic should be prevented from driving through the spill. The City's Public Works crew will use delineators, cones and even City vehicles to create a safe traffic diversion around the spill area. Pedestrians will be diverted to a safe area. Care will be taken not to direct pedestrians into traffic lanes.

In the event that the spill is located in a high traffic area, the Public Works crew will seek assistance from the City's Police Department (Non-Emergency) at (323) 587-5171.

SECTION 5: BLOCKAGE REMOVAL
The Street Supervisor, or senior crew member, will assess the problem and assign the crew job duties in order to remove the blockage from City-owned infrastructure.

SECTION 6: BYPASS
If the blockage is not relieved within the first few attempts and is projected to exceed the capacity of the temporary flow containment area, it is crucial that bypass procedures are followed immediately. The Street Supervisor, or senior crew member, will locate the nearest downstream manhole that can accept the additional flow, and set up an appropriately sized pump. The pump discharge hose should be secured or placed far enough into the receiving manhole that it will not come out during pumping. The pump and pump hose should be protected from traffic by barricades.

SECTION 7: REPORTING AND NOTIFICATION
For any discharges of sewage that result in a discharge to a drainage channel or a surface water, the City, as soon as possible but not later than two (2) hours after becoming aware of the discharge, notify the Vernon Department of Health & Environmental Control, State Office of Emergency Services (for discharges of 1,000 gallons or more of sewage), Los Angeles County Health Department (for discharges that enter L.A. River), Long Beach City Health Department (for significant spills into L.A. River that may affect City of Long Beach) and the Los Angeles Regional Water Quality Control Board. Notification to the Los Angeles Regional Water Quality Control Board should be followed-up with a fax or email, and should also specify that the State Office of Emergency Services, Los Angeles County Health Department and Long Beach Health Department have already been notified.

SEWER AND STORM DRAIN PROGRAMMED

MAINTENANCE SYSTEM

CITY OF VERNON

DEPARTMENT OF PUBLIC WORKS

SEWER AND STORM DRAIN

PROGRAMMED MAINTENANCE SYSTEM
The objective of this Programmed Maintenance System is to ensure that the sewer and storm drain systems in the City of Vernon perform as designed without service interruptions due to lack of maintenance. The City's sewer and storm drain systems receive a wide variety of discharges and with nearly 1000 manholes in the sewer system alone, it is impractical to attempt to maintain the system without a programmed maintenance approach. When fully implemented, this Programmed Maintenance System will keep the sewer and storm drain systems operating properly and provide important data, to be used to identify trouble spots before they cause problems.

Since most of the work related to this Programmed Maintenance System will take place in the street, it is important that traffic safety be put first. Always use proper delineation when occupying a traffic lane. If, at any time, it is necessary to divert traffic into opposing traffic lanes, a flagman or flagmen MUST be used. If adequate personnel are not available immediately, wait until the job can be performed safely before blocking traffic. Whenever possible, try to schedule the appropriate crews ahead of time to avoid unnecessary delays. Failure to follow standard traffic safety procedures when working in the street can have serious consequences for City personnel, the City itself, and the public.

SEWER SYSTEM

1. Inspection
All aspects of the sewer system shall be inspected as a part of this Programmed Maintenance System. The first and most visible part of the sewer system is the manhole frame and cover. The condition of each frame and cover should be checked for damage, fit, and wear. The frame and cover should also be flush with the street level and any sags should be recorded. Also, a record should be made of any signs of asphalt deterioration around the manhole that could result in rainwater infiltration.

Next, the condition of the manhole structure should be checked. Remember to use confined space entry techniques whenever opening and/or entering a manhole.

The walls of the manhole should be structurally sound and free from debris. Brick manholes should' be checked for loose or missing bricks and deteriorating grout.

Concrete manholes should be checked for the condition of the concrete coating as well as evidence of concrete deterioration. The condition of the shelf (or bench) including structural deterioration as well as the presence of debris on the shelf should be recorded. If the manhole has any other lines entering the structure, such as in the case of junction or drop manholes, the location of these lines should be recorded.

Finally, the amount of cockroaches present in the manhole should be recorded.

After evaluating the physical attributes of the manhole structure, attention should be diverted to the actual flow of wastewater. An estimation of the flow rate (half full, quarter full, etc.) should be made as accurately as possible. The nature of the flow (color, unusual odor, large amounts of grease or debris, etc.) should also be recorded.

These observations should be made as carefully as possible but they will be used for general information only. Specific data on flow rates and wastewater quality will be obtained through separate programs.

2. Cleaning
If debris or grease is present on the walls and/or shelf of a manhole, the debris should be cleaned off using a high pressure water sprayer. Care should be taken not to damage the structure during the cleaning process. Main line cleaning should be accomplished with the Jetter truck. While jetting, the operator must pay close attention to the water jetting back through the manhole to see if any solid matter is being drawn back into the manhole. If material is being drawn back, the operator should try to identify the material. If large amounts of grease are dislodged, another crew should be stationed at the next downstream manhole to chop up any big chunks to prevent clogging the line further downstream. In all cases, if unusual amounts of grease or debris are encountered, a supervisor should be contacted to determine the best course of action.

3. Insect Control
Insects, mainly cockroaches, can thrive in the sewer environment. These unwanted guests can spread disease from contact with waste water and also physically damage a sewer system. For these reasons, the populations of insects within the sewer system must be controlled by the use of insecticides. Insect control spraying should only occur during the weather that will produce the best result. For the currently used insecticide, the month of June has been identified as the optimum time of year to apply the product. The insecticide shall be applied in accordance with the manufacturer's recommendations. Use all required safety gear and traffic control techniques when applying the product.

4. Record Keeping
Record keeping is a vital part of any Programmed Maintenance System. The data collected will be entered into a computer where it can be easily analyzed and sorted.

The sewer inspection data shall be recorded on the attached Sewer Inspection Record sheet. The use of this standardized form will speed the collection of data in the field as well as set the format for data entry into the computer. These forms shall be turned in for computer entry at the end of each week. It is important that the data collected on this form be as accurate as possible. The City's sewer maintenance database is only as useful as it's data is accurate.

When completing the Sewer Inspection Record sheet, pay close attention to all entries. If a particular entry item does not apply to the manhole in question, mark the space “N/A”. There are several places where the relative condition of a specific element of the sewer system is to be estimated. Values ranging from Good to Very Poor should be judged with respect to the element in question. For instance, in order to receive a Good rating, the frame and cover of a manhole should fit well, be undamaged, and have good asphalt all around. A Very Poor rating would indicate that the frame and cover are severely damaged and are in need of immediate replacement. Values in between Good and Very Poor should be assigned depending on the severity of the damage. A brief description of the damage, if any, should be made in the comments area at the bottom of the form.

When assessing the condition of manhole walls, assign Good ratings to manholes that have no apparent defects. Peeling coatings and loose bricks are common defects in manhole walls and the severity of the defects should be reflected with either a Fair or Poor rating. The Very Poor rating should only be assigned to a manhole that is in immediate need of repair. Again, a brief description of the defects should be made in the comments section at the bottom of the form. Evidence of a sewer surcharge or backup will be a coating of waste water residue on the manhole walls with a "ring" at the high water mark. If such evidence is present, record the approximate high water height above the shelf in the comments section at the bottom of the form.

The condition of the invert and shelf is somewhat more difficult to quantify. Some defects may not be visible through the waste water. If the flow through the invert is smooth and no debris is visible on the shelf, the invert and shelf should be given a Good rating. Disrupted flows due to debris or structural damage and the presence of debris on the shelf will give either a Fair or Poor rating depending on the severity of the damage. A Very Poor rating should be assigned if there is a substantial disruption of the flow that cannot be repaired with normal cleaning. A Very Poor rating should also be given if the invert shows structural damage that allows waste water to leak out of the sewer system.

Again, briefly describe the nature of the defect in the comments section at the bottom of the form. On the reverse side of the Sewer Inspection Record are several diagrams showing sewer invert types. Determine which of the diagrams matches the invert in the manhole and enter the letter below the diagram in the corresponding space on the form.

If the invert type does not exactly match a diagram but is only slightly different, record the letter of the closest match. If there is absolutely no match, enter an X and draw a simple sketch in the blank diagram. If there are additional laterals or mains entering the manhole, note the size of each in the comments section of the Inspection Record. Also record the distance from invert to invert of any drop laterals or connections in the manhole.

STORM DRAIN SYSTEM

1. Inspection
Storm drain catch basins are the principal focus of the storm drain section of this Programmed Maintenance System. As the primary entrances to the storm drain system, catch basins play a vital role in the control of storm water. Catch basins are built into the street, usually in the sidewalk with an opening in the curb face. Since they are located close to traffic areas, catch basins are subject to damage from vehicles. With this fact in mind, damage to the structure caused by vehicular traffic should be checked for first.

Look for signs of damage such as cracked or broken concrete on the sidewalk or at the curb face entrance.

Another aspect of catch basin maintenance has nothing at all to do with the collection of storm water. Catch basins may collect storm water, but they also double as sidewalks, and as such must be safe to walk on. Any cracks, displacements, or tripping hazards must be noted and scheduled for repair. The access manhole cover should be flush with the surrounding concrete and fit well. When evaluating a small crack, remember that a nasty fall can come from a displacement as small as 1/4 inch high! While inspecting the exterior of the catch basin, look in the gutter for any signs of staining or water draining into the catch basin while it is not raining. Any nonrainwater discharges should be recorded and the source identified. As a general rule, only rain-water is allowed to enter the storm drain. If any other liquids are entering a catch basin, appropriate actions should be taken as soon as possible.

After the exterior of the catch basin has been inspected, the interior inspection should begin. As always, use confined space entry techniques whenever opening and/or entering a catch basin. The first thing to look for is debris. While all catch basins collect a certain amount of trash, some collect unusually large amounts. The relative amount of debris should be recorded. After the debris has been removed using the cleaning techniques to follow, the general condition of the structure should be assessed. Any cracks in or degradation of the concrete interior of the catch basin should be noted. Also check for any inlet connections other than the curb face inlet. lf any other inlets are found, the address of the property to which the inlet is connected should be recorded.

In addition to inspecting each catch basin, the manholes into the main storm drain lines must be checked. The physical aspects (such as manhole frame and cover, walls, invert, etc.) should be checked in much the same manner as the sewer manholes.

The pipe, however, should be dry unless it is raining or has recently rained. While it is true that there are some legal storm drain discharges, any storm drain that runs in dry weather must be investigated. The responsibility of sewer and storm drain personnel is to try to identify the source and notify a supervisor for appropriate action. Important information to report includes the date and time that the flow was observed, the location where the flow enters the storm drain, and the nature of the discharge. If the flow is clearly coming from an above ground source, note the address of the discharger.

Otherwise, try to isolate the location of the source to between two manholes. In any event, this information must be relayed to a supervisor in a timely manner so appropriate action can be taken. Again, it is the responsibility of the sewer and storm drain inspection personnel only to report suspicious discharges to a supervisor. Any and all enforcement of storm water laws shall be left to the appropriate agencies.

2. Cleaning
Improper cleaning of catch basins can lead to serious problems during wet weather. For this reason, particular care must be taken to ensure that the system will flow freely when called upon to do so. As always, use confined space entry techniques whenever entering a catch basin. The first step in the cleaning process is to make sure that there is no hazardous materials in the catch basin. Use a rake or similar tool to move the debris around to ensure that there is no hazardous materials present. If hazardous materials are encountered, they should be left alone until a representative of the Fire Department can be summoned to the scene to determine how to handle the hazardous material. Don't take any chances with hazardous materials. Once the catch basin is free of hazardous materials, the debris should be removed using the vacuum truck.

Once the catch basin has been cleaned thoroughly and has been proven safe for entry using confined space entry techniques, the lateral must be visually checked for obstructions. Physically climbing into the catch basin and looking down the lateral using a flashlight or mirrors for light is the only way to positively verify that the lateral is clear. If the lateral is clogged, or if the lateral turns so it is impossible to see all the way to the main line, the lateral must be cleaned by using the jetter or whatever means necessary to clear the line. If it is necessary to clean the lateral, a second visual check shall be performed to ensure that the obstruction has been removed. It is very important that every catch basin lateral be free from obstructions.

If debris is encountered in a storm drain main line, it must be removed. If large amounts of dirt, sand, or other sediment is found on a storm drain main line, an effort must be made to identify the source. Vacant lots and construction projects can produce a very muddy runoff that can silt up in the main. Dirt, sand, and other debris can also be a sign of a damaged or broken line. In any case, sediment in the line should be reported to the supervisor so that appropriate action can be taken. It may be necessary to pre-form an internal inspection of the pipe.

3. Record Keeping
The data gathered during the storm drain inspection and cleaning shall be recorded on the attached storm drain inspection record. These standardized forms should be completed in much the same way as the sewer inspection records. It is crucial to the success of this program that the data entered onto the forms be accurate. Data based on assumptions is frequently inaccurate. If there is any question on any data, do not guess. It is better to leave the form blank than to record inaccurate data.

The storm drain inspection records have been separated into two parts; one for the catch basins and one for the main line manholes. The same sort of estimates of the condition of manholes made during the sewer inspection will be made again with the storm drain system. A Good rating means that there is no apparent damage. A Fair rating means that there is minor damage that does not need repair. A Poor rating means that the damage is severe enough to need repair, but the repairs do not necessarily need to happen right away. A Very Poor rating shall be reserved for damage that needs to be repaired right away.

Summary
This Programmed Maintenance System will provide a guideline for the inspection and maintenance of the City's sewer and storm drain systems. This Programmed Maintenance System will also allow us to better understand the dynamic nature of the sewer and storm drain systems. ln the long run, this Programmed Maintenance System will provide a better maint8ined sewer and storm drain and will reduce wasted efforts by identifying small problems before they become large one

PUBLIC OUTREACH FOR FOG CONTROL

FOG REGULATIONS
Frequently Asked Questions (FAQs)

General Questions
What is the Fats, Oils, and Grease (FOG) Ordinance and why does it exist?

Chapter 13.25 of the Vernon Municipal Code (VMC) establishes rules governing the discharge of fats, oils, and grease (FOG) into the City's sewer system. FOG discharged by food service establishments is one of the leading causes of sewer line blockages and sanitary sewer overflows (SSOs). The ordinance is designed to protect the sewer infrastructure, prevent spills, and maintain compliance with state and federal water quality laws. To view Chapter 13.25 of the VMC in its entirety, please visit www.cityofvernonca.gov/FOG.

Who must comply?
All food service establishments (FSEs) operating within the City of Vernon must comply. An FSE is broadly defined as any commercial entity operating in a permanent structure where food is stored, prepared, served, manufactured, packaged, or otherwise handled for sale or public consumption.

When did this go into effect?
Ordinance No. 1312 was adopted on April 21, 2026 and became effective May 22, 2026. There is a January 1, 2030 deadline which applies to FOG Discharge Permit requirements and grease interceptor installation for certain existing FSEs.

Permits
Do I need a permit?
Yes. Every FSE that discharges or may discharge FOG into the City's sewer system must obtain a FOG Discharge Permit. You must apply for a permit when you apply for a new or renewed business license. All FSEs must hold a valid permit no later than January 1, 2030. (VMC § 13.25.120)
How do I apply for a permit?
Submit a completed application in the form prescribed by the City, along with the required permit fee. Your application must include your FSE's name, address, owner information, food types and processes, assessor's parcel number, and property owner

FOG REGULATIONS
Frequently Asked Questions (FAQs)

or lessor details. The City may also require site plans, plumbing diagrams, and other documentation. (VMC § 13.25.130)
For how long is a permit valid?
FOG Discharge Permits are issued for a period of up to three years. You must renew your permit before it expires and pay all outstanding fees before renewal will be granted. (VMC § 13.25.170)
Can I transfer my permit to a new owner or location?
No. FOG Discharge Permits are non-transferable. Any permit transferred to a new owner, operator, or facility is automatically void. The new operator must apply for their own permit. (VMC § 13.25.180)
Grease Interceptors
What is a grease interceptor and do I need one?
A grease interceptor is an underground multi-compartment device that separates and retains FOG from wastewater before it enters the sewer system. Unless the City grants a conditional waiver, all FSEs are required to install, operate, and maintain an adequately sized grease interceptor. (VMC § 13.25.090)
When must I install a grease interceptor?
New construction FSEs must install a grease interceptor before commencing any discharge. Existing FSEs connected to sewer hot spots must comply by January 1, 2030. (VMC § 13.25.090)
What if installation is impossible or impractical at my location? You may apply to Vernon’s Director of Public Works (Director) for a conditional waiver allowing an alternative pretreatment technology, provided it is at least as effective as a grease interceptor. You must demonstrate effectiveness through at least three months of downstream visual monitoring at your own expense. Waivers are valid for up to three years and may be revoked if conditions change. If no physical installation is possible at all, the City may charge a Grease Disposal Mitigation Fee. (VMC § 13.25.100)
How often must I clean and maintain my grease interceptor? Grease interceptors must be fully pumped and cleaned often enough that combined FOG and solids never exceed 25% of the total liquid depth. At minimum, maintenance must occur at least every six months. Your actual frequency may be

FOG REGULATIONS
Frequently Asked Questions (FAQs)

higher depending on your operations. Maintenance records must be kept for at least three years. (VMC § 13.25.240)
Day-to-Day Compliance
What is the discharge limit for oil and grease?
No FSE may discharge total dispersed oil and grease exceeding 650 mg/L, and no visible floatable oil and grease may be discharged at any time. (VMC § 13.25.060) What are best management practices (BMPs) and am I required to follow them? BMPs are operational practices that minimize FOG from entering the sewer system. All FSEs are required to implement BMPs, which include: installing drain screens in food prep areas; storing and disposing of waste cooking oil in sealed containers using licensed waste haulers; disposing of all food waste in trash (never sinks); dry-wiping pots and pans before washing; posting BMP guidelines prominently in kitchen and wash areas; and training all employees at least twice per year. (VMC § 13.25.230) Can I use chemical or biological additives to break down grease? No, not without prior written authorization from the Director. Emulsifying additives and biological grease remediation products are prohibited without that written approval. (VMC § 13.25.070)
What do I do if I have an accidental FOG discharge?
Immediately notify the City by telephone using the number in your permit. If the discharge could cause sewer blockages or SSOs, also contact the Health & Environmental Control Department and Public Works Department. Written confirmation of the incident must be submitted to the Director within three business days, describing the cause, immediate corrective actions taken, and steps to prevent recurrence. (VMC § 13.25.280)
Penalties and Enforcement
What happens if I don’t comply?
Non-compliance can result in: criminal misdemeanor charges with fines up to $1,000 and/or imprisonment up to six months per violation per day; civil penalties up to $25,000 per violation per day; permit suspension or revocation; and cost recovery from your business and/or your property owner for any City sewer cleanup, repair,

FOG REGULATIONS
Frequently Asked Questions (FAQs)

and remediation costs, which may be collected as a lien or special assessment on the property. (VMC §§ 13.25.310–13.25.350)
Can I appeal a City decision?
Yes. You may appeal any final written decision of the Director to the City Administrator by filing a written Notice of Appeal with the City Clerk within 15 calendar days of service of the Director's decision. The City Administrator's decision is the City's final administrative action and is subject to judicial review under Code of Civil Procedure Section 1094.5. (VMC § 13.25.340)
