Chapter 1 Introduction This Sewer System Management Plan (SSMP) has been prepared in compliance with the requirements of the State Water Resources Control Board (SWRCB), Order 2006-0003 DWQ, Statewide General Waste Discharge Requirements (WDRs) for Sanitary Sewer Systems. The goal of the WDRs is to provide a consistent statewide approach for reducing Sanitary Sewer Overflows (SSOs). This chapter includes a brief overview of the City of Coronado’s (City) service area and sanitary sewer system, a summary of the regulations that serve as the impetus for the development of this SSMP, and the purpose and organization of this SSMP.

1.1 Service Area and Sewer System

The City of Coronado is located on a peninsula on the western side of San Diego Bay. The City serves a population of approximately 26,500 customers within a 13.5 square mile area. The City has numerous hotels and motels, including the Hotel Del Coronado, and experiences a large tourist population, especially during the summer months, as well as a large daytime workforce to support the navy base. The City’s commercial area is primarily located along Orange Avenue, and includes small retail shops and restaurants. Shown in Figure 1-1 is the City’s boundary. The City’s wastewater collection system consists of approximately 45 miles of gravity and pressurized pipelines, approximately 750 manholes, and sixteen (16) pump stations. On average, the City, which is considered built-out, transfers approximately 3.2 million gallons per day (MGD) of sewage, including sewage flows from the two navy bases, the Naval Amphibious Base (NAB) and the Naval Air Station North Island (NASNI). Although the NAB and NASNI own and operate independent sewage facilities, they contract with the City to convey the flows through the City’s system to the Transbay Pump Station from where it is pumped to the City of San Diego’s Metropolitan wastewater collection system and conveyed to the Point Loma Wastewater Treatment Plant.

1.2 Waste Discharge Requirements

On May 2, 2006, the SWRCB adopted Order 2006-0003 DWQ, the Statewide General Waste Discharge Requirements for Sanitary Sewer Systems, which requires all federal and state agencies, municipalities, counties, districts, cities, and other public entities that own or operate a sanitary sewer system greater than one mile in length to comply with the elements of the WDRs. The WDRs serve to provide a unified statewide approach for reporting and tracking SSOs, establishing consistent and uniform requirements for SSMP development and implementation, establishing consistency in reporting, and facilitating consistent enforcement for violations. On June 27, 2006, the Executive Director of the SWRCB executed a memorandum of agreement with the California Water Environment Association (CWEA), outlining a strategy and time schedule for CWEA to provide training on the (1) adoption of the program, (2) SSO database electronic reporting, and (3) SSMP development. This agreement also extended the completion dates for most tasks by six (6) months from the dates shown in the adopted WDRs.

The WDRs include directives for owners and operators of sanitary sewer systems to demonstrate adequate and efficient management, operation, and maintenance of the sanitary sewer system. Generally, the WDRs require that:

a) In the event of an SSO, all feasible steps be taken to control the released volume and prevent untreated wastewater from entering storm drains, the bay and ocean, etc.

b) If an SSO occurs, it must be reported to the SWRCB using California Integrated Water Quality System (CIWQS), the online reporting system developed by the SWRCB. The City completed its enrollment into the program and the demographic questionnaire, and electronic reporting commenced in November 2006.

c) An SSMP with all mandatory elements be developed and approved by the governing body that owns or is responsible for the operation of the sanitary sewer system. The SSMP must include provisions to provide proper and efficient management, operation, and maintenance of the sanitary sewer system.

This document includes an Operation and Maintenance Program; a Fats, Oils, and Grease Control Program; a Sanitary Sewer Overflow Response Plan; and a System Evaluation and Capacity Assurance Plan as well as the remaining components which comprise a comprehensive SSMP. The completion dates for each mandatory element are determined according to the size of population served by the federal and state agencies, municipalities, counties, districts, cities, and other public entities that own or operate a sanitary sewer system. Based on an estimated population of approximately 26,500 customers, the City must comply with the schedule provided for agencies that serve a population between 10,000 and 100,000.

1.3 Purpose

The City recognizes the importance of preventing sewage spills not only to safeguard public health and safety, but to protect of our surrounding waters and the overall environment. This SSMP is designed to ensure continuous improvement in system performance, response, monitoring, data recording, and documentation for future system assessments. The City considers the completeness and practicality of the SSMP a critical component for its long range plans to comply with all applicable regional, State, and Federal requirements under the Clean Water Act (CWA), the San Diego Regional Water Quality Control Board and the WDRs. This document provides a summary of the action plan implemented by the City to comply with the sanitary sewer system requirements imposed by the WDRs and other governing agencies. It also includes the specific details of the activities and procedures that City staff follows to implement the various programs encompassed in its overall efforts to efficiently manage, operate, and maintain its sanitary sewer system and facilitate the reduction and potential elimination of SSOs.

1.4 SSMP Elements and Organization

Chapter 2 Goals and Objectives The following sections include a summary of the City’s goals that reflect its commitment to continue its effort towards ensuring the effective and efficient management, operation and maintenance of the sanitary sewer system.

2.1 Regulatory Requirements for Goals Element

This first element of an SSMP requires that the City institute goals to properly manage, operate, and maintain all parts of the sanitary sewer system. Establishing goals allows the City to manage its sanitary sewer system to achieve its ultimate goal of reducing and preventing SSOs and to properly mitigate any SSOs that may occur. To achieve the goals established by the City, it becomes imperative for City staff to consistently maintain quality working procedures and continue efforts towards identifying and implementing improvements in managing the sanitary sewer system. The WDRs require that the City, at a minimum, develop goals that incorporate and achieve the following:

• Properly manage, operate, and maintain all parts of the sanitary sewer system;

• Provide adequate capacity to convey peak flows;

• Minimize the frequency and volume of SSOs;

• Mitigate the impacts of SSOs if they occur;

• Inform and educate the public on programs, projects, and issues related to the sanitary sewer system; and

• Properly implement regulatory notification and reporting requirements.

2.2 Goals for City System Maintenance and Management

The City has establish several internal core objectives to allow City staff to focus on complying with the WDRs, and to developing and implementing strategies and procedures to achieve successful overall management and maintenance of the sanitary sewer system. Goals promote unified efforts towards implementing improvements as they affect the operations, maintenance, and management of the sanitary sewer system. They also reflect performance, safety, levels of service, resource use, and other criteria. The City’s ultimate goals include operating and maintaining all portions of the City’s sanitary sewer system to minimize the potential for SSOs and to quickly and effectively mitigate the impacts associated with an SSO if it were to occur so as to protect life, environment, and property while adhering to regulatory requirements. To achieve these goals, the City’s SSMP includes methods for ensuring that adequate capacity to convey the peak wastewater flows is

Chapter 3 City Organization and Communication An organizational chart for the City’s Public Services Division serves to identify the administrative, maintenance, and management positions responsible for implementing, managing, and updating the overall measures included in this SSMP. This chapter identifies the City staff who is responsible for implementing the plans and procedures included in the SSMP, responding to SSO events, and meeting the SSO reporting requirements. The communication plan that accompanies the organizational chart serves to define the role of each position to ensure that all elements of this SSMP are addressed on a regular basis and that all appropriate staff is properly informed. A specific response and notification plan to document the SSO emergency response and reporting procedures was developed and is included in the City of Coronado Sanitary Sewer Overflow Response Plan (SSORP) included in Appendix E. The response procedure identifies the staff positions responsible for managing the SSO response, investigating the SSO cause, and reporting the SSO to the appropriate parties. The SSORP also includes a consolidated list of contact information of key personnel and contractors available to respond to SSOs. The sequence of communication for reporting SSOs, and the appropriate agencies to be notified, is also included.

3.1 Regulatory Requirements for the Organization and Communication Element

It is required that the City’s SSMP clearly identify the staff responsible for implementing measures outlined in this SSMP. The WDRs require that the City identify the following:

a) The name of the responsible or authorized representative;

b) The names and telephone numbers for management, administrative, and maintenance positions responsible for implementing specific measures of the SSMP program. The SSMP must identify lines of authority through an organization chart or similar document with a narrative explanation; and

c) The chain of communication for reporting SSOs, from receipt of a complaint or other information, including the persons responsible for reporting SSOs to the State and Regional Water Board and other agencies if applicable (such as County Health Officer, County Environmental Health Agency, and/or State Office of Emergency Services).

3.2 Discussion on Organizational Structure

The City’s organizational structure for Public Services’ Operation and Maintenance Services Division, which is primarily responsible for implementing and overseeing the SSMP and the related plans and procedures, is described in the following sections. Additionally, the general responsibilities of the personnel and chain of communication are included.

The Management Analyst coordinates with other City departments and outside agencies and provides administrative support to the Director of Public Services. The Management Analyst assists with implementing division goals, policies and procedures, coordinating work plans and budget information for the Director of Public Services that is necessary for managing annual budgets for the various divisions of the Public Services Department.

3.2.4 Authorized Representative

Currently, the Director of Public Services is identified as the City’s LRO and authorized representative registered with the State of California to officially sign and certify SSO reports submitted via California Integrated Water Quality System (CIWQS), the state’s on-line reporting system. As well, the LRO is responsible for certifying the SSMP milestones. The City has identified the Public Services Supervisor as an additional LRO and the Management Assistant as a data submitter.

3.3 City Communication Structure for Collection System Issues

Communication of activities is important in order to keep managerial staff informed of successes and potential problems. Additionally, implementation of the various elements of the SSMP will require constant coordination among the various divisions identified in the organization chart. Therefore, clearly identifying the specific positions and staff as well as establishing communication protocols is necessary to ensure the appropriate personnel are properly informed to respond to sanitary sewer system related issues in the most effective and efficient manner.

3.3.1 SSMP Communication Structure

Continual communication between Public Services and the Engineering Department, as well as along the levels of hierarchy facilitates and supports activities that allow the Wastewater Operations and Maintenance Division to inform the appropriate staff about the operation and management of the collection system. Generally, the communication plan will follow the chain of command identified in the organizational chart. Specific levels of authority will be required to facilitate implementation and enforcement of the plans and procedures developed for the SSMP. As the various plans and procedures are implemented, an assessment as to the effectiveness of the plans will best be determined by the labor force that executes and evaluates the immediate impacts of the plans and procedures. Efficient and timely responses will be essential to ensure that the adopted plans and procedures are effective for the management and operation of the wastewater system. Figure 3-3 shows the communication protocol that the City should follow for the SSMP. Figure 3-3 also provides a summary of general responsibilities among the staff as it affects the


3-10

management, operation, and maintenance of the City’s sanitary sewer system. The responsibilities listed are to illustrate the overall importance of continual communication within the organization regarding wastewater related issues.

3.3.2 SSO Response and Communication Structure

A communication structure related specifically to SSO response and reporting is discussed in Chapter 7 of this SSMP and more thoroughly documented in Appendix E, which contains a copy of the City’s SSORP. Notifications may be received via telephone calls. Calls or complaints of actual or possible SSOs received via telephone are routed to the Wastewater Operations and Maintenance staff from either the Public Service’s front desk or the Coronado Police Dispatch Center. If a Wastewater Operations and Maintenance staff member is not available or non-responsive, then the designated backup staff member is notified. The City staff member to arrive first at the location is considered the First Responder. The First Responder will determine whether to direct additional Wastewater Operations and Maintenance staff, other City personnel, and/or approved contractors to the SSO location if the SSO cannot be fully contained or recovered or if it has reached public waters. The information obtained during the initial notification of a possible SSO may warrant the First Responder, in his/her best professional judgment, to dispatch Wastewater Operations and Maintenance staff or other City personnel before proceeding to the reported SSO location. Notifications to the following staff members and agencies will be performed as required:

• Director of Public Services

• Public Services Supervisor

• County Department of Environmental Health

• Governor’s Office of Emergency Services

• Coronado Police Department (as needed)

• Coronado Fire Department (as needed)

• San Diego Regional Water Quality Control Board (as needed)

• Coronado Risk Management (when a public SSO enters a home or business)

• City of Coronado Code Enforcement (when a violation of City Codes is noted) Other staff that will be notified, especially if the SSO could not be fully contained or recovered, or if it reaches public waters, includes:

• City Manager

• Assistant City Manager Notification to the City staff listed above is required in anticipation of possible media coverage and heightened scrutiny over the response efforts. The City Manager can also determine whether it would be prudent to notify the Mayor and City Council.

Chapter 4 Legal Authority To prevent SSOs to the maximum extent possible and meet state and federal requirements, each governing agency must ensure that its existing codes, ordinances, policies and procedures include the necessary requirements to implement and fulfill the specific needs of the agency, and to protect the health and safety of people, property, and environment. This chapter of the SSMP includes a discussion of the City’s current legal authority for the collection and conveyance of wastewater, and includes recommended revisions to the City’s ordinances.

4.1 Regulatory Requirements for Legal Authority Provisions

The WDRs require that the City show, through ordinances, service agreements, or other legally binding procedures, that the City possesses the legal authority to:

a) Prevent illicit discharges into its sanitary sewer system including, but not limited to, inflow and infiltration (I/I), storm water, chemical dumping, unauthorized debris, and cut roots, etc.;

b) Require that sewers and connections be properly designed and constructed;

c) Ensure access for maintenance, inspection, or repairs for portions of the lateral owned or maintained by the City;

d) Limit the discharge of fats, oils, grease, and other debris that may cause blockages; and

e) Enforce any violation of its sewer ordinances.

4.2 Background for Legal Authority

The California Water Code of the California Code of Regulations, the Federal Clean Water Act of the United States Code, and the California Waste Discharge Requirements grant the City the authority to establish codes, agreements, policies, and procedures for the construction, operation, and maintenance of a wastewater collection system, and the ability to enforce the necessary requirements. Below is a discussion of the relevant sections granting this authority. California Water Code Section 13271, California Code of Regulations: Section 13271 of the California Water Code, Title 23 of the California Code of Regulations, prohibits the discharge of sewage and hazardous material into the waters of the State and requires the proper notification of authorized agencies in the event of an SSO. Entities which do not properly follow the requirements of this section may be found guilty of a misdemeanor and punished by fine, imprisonment, or both. Clean Water Act, Section 1251 of Chapter 33 of the United States Code: In 1972, the federal Congress enacted the Federal Water Pollution Control Act, commonly known as the Clean Water Act (CWA). The CWA prohibits the discharge of pollutants, including sewage, into

Legal Authority

4-2

public waters of the United States. The federal government has the authority to enforce compliance with the CWA via specific permits, such as National Pollutant Discharge Elimination System (NPDES) permits, as well as court action such as administrative orders and consent decrees. Code of Federal Regulations, Title 40, Protection of the Environment: The Environmental Protection Agency (EPA), in its general pretreatment regulations (40 CFR Part 403), and the City, in its municipal code, prohibit any user from discharging solid or viscous pollutants, such as fats, oils, and grease (FOG) wastes, in amounts which will cause obstructions (blockages) to the flow in the wastewater system and interfere with the operation of the wastewater system. California Waste Discharge Requirements: On May 2, 2006, the SWRCB adopted the Statewide General Waste Discharge Requirements for Sanitary Sewer Systems, Order No. 2006-0003 DWQ. The WDRs are applicable to all federal and state agencies, municipalities, counties, cities, and other public entities that own or operate sanitary sewer systems greater than one mile in length that collect and/or convey untreated or partially treated wastewater to publicly owned treatment facilities in the state of California. Specifically, the WDRs require all affected agencies, municipalities, counties, cities, and other public entities to take a proactive approach to ensure a system-wide operation, maintenance, and management plan is established to effectively reduce the potential, quantity, and frequency of SSOs that may occur and impact surface or ground waters, threaten public health, adversely affect aquatic life, and impair the recreational use and aesthetic enjoyment of surface waters.

4.3 Summary and Evaluation of the City’s Existing Legal Authority

The City’s legal authority and powers pertaining to the City’s wastewater collection system originate from the powers granted by the State and Federal governments, and are codified in City of Coronado Municipal Code. Title 60.04 of the City’s Municipal Code is specific to the City’s wastewater collection system. These codes are included in Appendix A for reference. The codes provide for the regulation of contributors to the City’s wastewater collection system through the issuance of permits and enforcement of general requirements. Through these codes the City establishes the authority to monitor and enforce activities, require user reporting, and set fees for the equitable distribution of costs. The following sections include a summary of the City’s existing codes as they apply to its sanitary sewer system.

4.3.1 Prevention of Illicit Discharges

The City is required to prevent discharges of illicit and undesirable substances from entering the wastewater collection system. Illicit discharges include, but are not limited to, the release of I/I, storm water, chemical dumping, unauthorized debris and constituents, and cut roots. Discussed below is the City’s Municipal Codes to control the discharge of the prohibited substances. Section 60.04.900, Prohibitions, includes a general description of the various types of substances restricted by the City from being directly or indirectly discharged into the collection system. This section of the ordinance provides the City the authority to regulate the specific type of substances permitted to be discharged into its wastewater collection system.


June 2009

4-3

Sub-Section H of Section 60.04.900, Prohibited Items, includes a description of the specific types of items prohibited from discharging into the City’s wastewater collection system. The descriptions of the prohibited substances included in this section are adequate and comprehensive as to the types of substances not permitted to be discharged into the collection system. Additionally, the City further restricts the substances allowable into the system by including a description of the effects on the system the City intends to avoid. Generally, the prohibited items include substances with characteristics that may cause:

• Obstructions to the flow in the sewer system;

• Interference with the operation of the POTW;

• Damage or create a hazard to City’s wastewater collection system structures;

• Damage or create a hazard to the City’s wastewater collection system equipment;

• Damage or create a hazard to City personnel;

• A public nuisance or create a hazard to life; and/or

• Interference with the maintenance of the sewage collection system. Regulating the type of substances allowable in the City’s wastewater collection system serves to protect and maintain its integrity.

4.3.2 Proper Connections and Construction

The City’s requirements for the design and construction of new, rehabilitated, and replaced sewer system facilities, including mains, tie-ins, service laterals, cleanout, manholes, and other system appurtenances, necessary to ensure the proper operation of the sewer system are summarized below. The City has adopted the Standard Plans and Specifications for Public Works Construction (Greenbook), 2006 edition; the San Diego Regional Standard Drawings (SDRSD) 2006 Update; and the City-annotated SDRSD 2007 (included in Appendix C), as the referenced standard specifications and drawings for public services projects. The City also uses the Standard Special Provisions for Permit Construction, which are included in Appendix D. The City requires that all public sewer mains within the City be constructed in accordance with the Greenbook, 2006 edition prepared by the American Public Works Association, the SDRSD 2006 Update, and the City-annotated SDRSD 2007. The documents include minimum design standards for sewer mains, sewer manholes, and sewer laterals, and general guidelines for common sewer rehabilitation options. Additionally, the City also requires compliance with the Standard Special Provisions for Permit Construction, adopted in May 2008 which is included in Appendix C. The provisions include additional requirements for the design and construction of manholes, sewer laterals, and connections to existing mains.

4.3.3 Accessibility for Maintenance, Inspection, and Repair

The City’s Municipal Code does not expressly document access requirements for maintenance or repair of the wastewater collection system. Instead, accessibility requirements for this

Legal Authority

4-4

purpose are managed through the plan reviews for new sewer service where City staff ensures that sewer system facilities are constructed to specific standards within the public right-of-way or within adequate, permanent easements. Section 60.04.180, Inspection and Sampling, of the City’s Municipal Code provides the City with the authority to access every facility that is involved directly or indirectly with the discharge of wastewater to the City’s wastewater system for inspection and sampling purposes. The facilities to which City staff have access include, but are not limited to sewers, wastewater pumping stations, pollution control plants, all industrial processes, FSE facilities or other facilities which discharge grease and oil at levels which can cause blockages to the sewer, industrial wastewater generation, conveyance and pretreatment facilities and all similar wastewater facilities. Although this section provides City staff the authority to access wastewater related facilities, it does not allow City staff to access the facilities for maintenance purposes or to perform these functions on systems that discharge domestic wastewater. In the event a site inspection reveals improper maintenance and\or cleaning and there is imminent danger to the City’s sewer facilities or the public, the City should have the authority to access the site and related facilities to perform the necessary maintenance and cleaning in an effort to prevent exposing the public to a health risk or hazard and compromising the operation of the City’s wastewater collection system. Additionally, the City should have access to the site for maintenance and cleaning purposes in the event an emergency occurs that requires the immediate cleaning of the sewer facilities discharging into the City’s wastewater system. It is recommended that the City’s legal authority be expanded to include access by City staff to sites for performing necessary maintenance and cleaning of sewer facilities which are determined to be in or may result in the violation of the provisions included in the code or the conditions of the permit. Also, provisions are recommended to provide staff access to sewer facilities that discharge domestic wastewater.

4.3.4 Limit Fats, Oils, and Grease Discharge

To limit the discharge of FOG and other debris that may cause blockages, the City’s Municipal Code addresses the requirement or potential requirement for sewerage pretreatment equipment. Section 60.04.144, Permit Conditions, Special (Food Establishments), addresses the requirement for the pretreatment of grease prior to it being discharged into the City’s wastewater collection system. This section gives the City authority to require an FSE to install an approved type grease pretreatment device in the waste line leading from the food preparation or cleanup where grease may be introduced into the sewerage system. Additionally, the City recently prepared The City of Coronado Fats, Oils, and Grease Control Program (FOG Control Program), that documents and establishes the formal procedures City staff implements to effectively minimize the direct or indirect discharge of all wastewater or waste containing FOG into the City’s wastewater collection system. It includes several components necessary to reduce the quantity of FOG discharged into the City’s wastewater


June 2009

4-5

collection system to achieve the goal of minimizing SSOs due to excessive FOG. The elements include:

• Kitchen Best Management Practices

• Grease Trap Installation, Operation and Maintenance Requirements

• Grease Interceptor Installation, Operation and Maintenance Requirements

• Notification Requirements

• Record Keeping and Reporting Requirements

• Permits, Inspection, and Enforcement

• Public Education

Food Service Establishments (FSEs) and other non-domestic waste and wastewater generating facilities are required to obtain a Food Establishment Wastewater Discharge Permit which sets forth the specific terms, conditions, and criteria required for compliance with the City’s Municipal Codes, FOG Control Program, and policies for each facility requiring connection to the City’s wastewater collection system. The City’s objective is to continue to implement and enforce actions against users of the wastewater collection system that violate the prohibition of discharging FOG into the wastewater collection system. The City will continue enforcement actions for noncompliance and it will be possible for other regulatory agencies, including the EPA or the State to initiate their own enforcement actions, if, in their opinion, the City does not implement adequate enforcement.

4.3.5 Violation Enforcement

The authority for the City to enforce penalties for violations of the City’s Municipal Code and other adopted policies as they pertain to its wastewater collection system is included in Section 60.04.190, Enforcement, of the municipal code. This section codifies the City’s authority to enforce violations with respect to the sanitary sewer system. Enforcement procedures for violations of the City’s provisions may include any of the following:

Administration: Any person found to be violating any provision of this chapter shall be served by the Director with written notice stating the location and nature of the violation. Within 30 days after the date of the notice, unless a shorter time is necessary due to the nature of the violation, a plan for the satisfactory correction thereof shall be submitted to the Director by the person found to be in violation. If the violation is not corrected by timely compliance, or a satisfactory correction plan submitted within the specified time, the Director may order any person to show cause why enforcement action should not be taken. A written notice shall be served on the person specifying the time and place of a hearing, the reason why the action is to be taken and the proposed enforcement action. The Director may propose any enforcement action reasonably necessary to abate the violation. Based upon the evidence presented at the hearing the Director shall determine the appropriate enforcement action which should be taken, if any.

Chapter 5 Operation and Maintenance Program This chapter of the SSMP discusses the City’s operations, maintenance and other related measures and activities as they pertain to its sanitary sewer system.

5.1 Regulatory Requirements for Operation and Maintenance Program

The WDRs require that the SSMP contain descriptive measures of the City of Coronado’s Operation and Maintenance Program (O&M Program) that are implemented by City staff to facilitate proper and efficient management and maintenance of the sanitary sewer system and the affected appurtenances. The WDRs require that the SSMP include a description of each of the following components as they apply to the City’s sanitary sewer system:

a) Maintenance of up-to-date sanitary sewer system map showing all gravity line segments and manholes, pumping facilities, pressure pipes and valves, and applicable storm water conveyance facilities;

b) 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 Preventive Maintenance Program should have a system to document scheduled and conducted activities, such as work orders;

c) Development of a rehabilitation and replacement plan to identify and prioritize system deficiencies and implant 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 and maintenance, and repair contractors to be appropriately trained; and

e) Development of equipment and replacement part inventories, including identification of critical replacement parts.

5.2 City’s Operation and Maintenance Program

The City prepared a comprehensive O&M Program which includes a summary of the City’s current procedures and practices as they pertain to the O&M activities related to its sanitary sewer system. The City’s O&M Program contains information pertaining to the following components for compliance with the WDRs:

O&M Program

5-2

• Inventory and Mapping of the Sanitary Sewer System Assets

• Preventive Maintenance Program

• Sanitary Sewer Overflow Response Plan

• Fats, Oils, and Grease Control Program

• Wastewater System Inspection and Assessment Program

• Capital Improvement Program Project Identification

• Equipment and Replacement Part Inventories

• Training and Safety Program

• Design and Performance Provisions

5.3 Discussion of Regulatory O&M Components

To address the components listed in Section 5.1 and as required by the WDRs, the following subsections provide a summary of the applicable O&M procedures currently being implemented. A copy of the O&M Program is included in Appendix B of the SSMP for reference.

5.3.1 Sanitary Sewer System Mapping

The location of the City‘s sewer pipes and associated appurtenances operated and maintained by the City are documented on laminated map books. The map books were prepared using as-built drawings information which is also included in the City’s geographic information system (GIS). Updates to the GIS information are typically generated by Wastewater Operations and Maintenance staff while performing routine operation and maintenance activities. Discrepancies between information contained on the map books and field conditions are manually documented on the map books. The map books, containing comments, are submitted to GIS staff for the updating of electronic files. For efficiency, GIS updates occur irregularly to accumulate several changes for editing at one time. The City is currently in the process of updating its map books to reflect newly installed and realigned wastewater and storm water infrastructure including conveyance facilities, manholes, and pumping facilities. As well, the updating process has included verification of existing information contained in the City’s system database. Completion of the conversion of the graphic information to the computerized mapping system, population of the GIS database, assignment of identifying labels to all pipeline segments and manholes, and establishment of a routine updating and maintenance procedure will enhance the City’s ability to effectively manage the system and facilitate implementation of an asset management program for the wastewater collection system.

5.3.2 Preventive Maintenance Program

The City is committed to a regular sanitary sewer system maintenance program. To minimize and prevent system blockages and preserve and extend the useful life of the sanitary sewer system, the City’s Preventive Maintenance Program primarily includes scheduled maintenance


June 2009

5-3

of wastewater facilities including sewer pump stations and wet wells and the routine cleaning of the wastewater collection system pipelines. The Preventive Maintenance Program also includes increased cleaning of known sewer system problem areas, routine root control, FOG control, and response to customer complaints. The Preventive Maintenance Program is further documented in the O&M Program. System Cleaning The scheduling and performance of maintenance and cleaning activities is currently performed by the City’s Wastewater Operations and Maintenance Division. Cleaning activities are manually scheduled on an annual basis and completed by drainage basin. A two (2) man crew (rotated among the six (6) Wastewater Operations and Maintenance staff members) is assigned to perform daily routine cleaning tasks. The City’s Wastewater Operations staff work daily to eliminate potential pipe and manhole blockages and to ensure relief valves and pump stations are operational. Additionally, crews clean high frequency maintenance locations (HFMLs) on a monthly basis. These locations include areas with pipeline sags and areas identified as having excessive amounts of grease accumulation and root concentrations. The cleaning of HFMLs is tracked and scheduled manually. Cleaning efforts are documented manually on daily reports. Documented information pertaining to sewer pipeline cleaning activities includes the section of pipe cleaned, lineal footage cleaned, the type of debris removed, names of staff performing the cleaning, and any additional pertinent comments. HFMLs identified as requiring repair are included on the City’s CIP list. Reports summarizing daily progress are generated by maintenance crews and submitted to the Public Services Supervisor to track progress and status of wastewater collection facilities. Daily progress reports and work-related forms are filed at the Operations Yard for future access and reference. Pump Station Maintenance The City’s Wastewater Operations and Maintenance staff are responsible for ensuring the proper operation and maintenance of its sixteen (16) pump stations. Maintenance of each sewer pump station includes checking and/or recording various pump station parameters, routine cleaning of wet wells, draining water from mechanical seals, and greasing pump bearings. As the maintenance activities are performed, maintenance efforts are manually documented by staff. The records are submitted to the Public Services Supervisor and maintained by the Public Services Department. Root Treatment A component of the City’s cleaning efforts includes utilization of the City’s jet-rodder/vactor and routine chemical treatment to minimize the potential for SSOs due to root-related problems. The City’s root treatment program is performed by a contractor retained by the City to perform routine chemical treatment of select portions of the City’s sanitary sewer system. The treatment includes the application of chemical root inhibitors to reduce or eliminate roots intruding into the pipes. As locations are identified for chemical treatment for root control, location information is

O&M Program

5-4

recorded and treatment is either scheduled with the contractor or performed by Wastewater Operations staff using products maintained at the Public Services Yard. Odor Control Wastewater Operations staff inspect the City’s wastewater pump stations equipped with odor control beds and/or ventilation systems to prevent odor related issues from arising, identify potential odor causing problems, and ensure the odor control systems are operational and functioning properly.

5.3.3 Sanitary Sewer System Inspection and Condition Assessment Program

Regular and systematic inspection and assessment of sanitary sewer system facilities provides a means to monitor the condition of the facilities, the effectiveness of maintenance operations, and provides a basis for identifying and scheduling capital improvements. As well, the overall assessment can be used to determine the funding required to repair, rehabilitate, and replace portions of the collection system and to prioritize the allocation of funds and optimize the expenditure and efforts to operate a sewer collection system. System Inspection and Assessment Approximately 100,000 lineal feet of the City’s wastewater system, including numerous manholes, were inspected and televised approximately ten (10) years ago, in 1998, by a contractor as part of updating the City’s Sewer Master Plan. Since the televising of the City’s wastewater collection system, City Wastewater Operations staff hve performed CCTV inspections after an SSO occurrence, at the request of the Engineering Department or in specific areas following the annual scheduled cleaning. Manholes are visually inspected by City staff during the annual cleaning of the sewer pipelines and defects are noted in the log books and evaluated for repair or replacement. Work orders for CCTV inspections are generated and tracked manually by Wastewater Operations staff. The pipelines inspected are manually documented by staff members in a log book and the information is utilized for recording, tracking, and reporting purposes. A copy of the wastewater collection system map book is kept in the CCTV van and is highlighted to track progress. Repair and Rehabilitation Projects The City’s Wastewater Operations and Maintenance Division is responsible for performing various types of wastewater facility repairs and rehabilitation improvements. Repair and rehabilitation work performed by maintenance crews may include point repairs at cracks, joints, and service interfaces, repairing collapsing or broken sewer pipe, and removing obstructions in the sewers that hinder flows and cleaning operations. Based on the information obtained from the CCTV and manhole inspections that occurred in 1998 and the frequent CCTV and manhole inspections that have been performed since, pipeline and manhole replacement projects have been identified and prioritized. Approximately five (5)


June 2009

5-5

segments per year have been replaced and have typically consisted of upsizing 6-inch to 8-inch pipelines. The Wastewater Operations staff is able to implement mitigation efforts and perform repairs for pipelines 6 to 8 inches in diameter to restore or replace failing wastewater collection sewer lines. Repairs for pipelines greater than 8 inches in diameter and repairs that require an extensive construction effort are directed to the Engineering Division to be performed by independent contractors retained by the City. CIP Development The Citys Engineering Department staff, coupled with recommendations provided by Public Services Wastewater Operations staff, prioritizes pipeline replacements and rehabilitations to address critical issues including structural integrity, effectiveness in reducing infiltration and inflow, effect on flow capacity, and community impacts. Based on the results of the City’s 2000 Master Plan document, in conjunction with the results of the CCTV inspection efforts performed as part of the Master Plan, and the CCTV inspections performed since the Master Plan was prepared, the City has prioritized the repair, rehabilitation, or replacement of deficient sewer pipelines, pump stations, and associated appurtenances. The City prepares a two- (2) year budget and annually updates the CIP project list. Projects are identified from a master list of needs. As additional projects are identified, they are prioritized for repair, rehabilitation, or replacement to ensure the proper management and protection of infrastructure assets. The time schedule for implementing the short- and long-term projects, plus a schedule for developing the funds needed for the capital improvement plan are also updated.

5.3.4 Training Program

Prior to performing any work on City facilities, City Wastewater Operations and Maintenance staff is trained on the existence and the provisions of the wastewater operations and maintenance policies, procedures, safety policies, and the equipment used. Training for operation of City equipment includes primarily “on-the-job” training in conjunction with bi-weekly “tailgate” meetings to discuss safety issues and operating procedures. The Public Services Supervisor documents the training subject, duration and staff attendance. The Public Services Supervisor documents the type of training staff members receive, which includes:

1. Confined Space

2. Trenching and Shoring

3. Pumps

4. Basic Electricity

5. Hydraulics

6. Jetting Techniques

7. Various Safety Procedures

O&M Program

5-6

As necessary and determined by appropriate managerial staff, training programs may also include supplemental technical training required to efficiently and safely perform specific job related duties.

5.3.5 Equipment and Replacement Part Inventories

The Wastewater Operation and Maintenance Division maintains an inventory of materials and equipment available for the necessary O&M activities on the City’s wastewater collection system. This inventory is included as an attachment to the O&M Program Technical Memorandum in Appendix B. The list is maintained and manually updated on a regular basis by Wastewater Operations staff. As well, funds are reserved for scheduled repairs and replacement of materials and equipment necessary for ensuring the proper maintenance and operation of the wastewater collection system. City maintenance vehicles and sanitary sewer system replacement parts are made readily accessible to operations staff. The replacement parts, maintained in the Public Services Yard, are for specific types of repairs performed by Wastewater Operations and Maintenance staff. Sufficient supplies are kept to quickly address various types of routine and emergency conditions that may occur. This minimizes the possibility of an overflow and restores service to the customer with minimal interruption. For repairs that extend beyond the City’s internal resource capabilities, the City retains the services of professional contractors.

Chapter 6 Design and Performance Provisions This chapter of the SSMP discusses the City’s design and construction standards and serves to fulfill the Design and Performance Provisions required by the WDRs.

6.1 Regulatory Requirements for Design and Performance Element

The WDRs require that the SSMP address the following:

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

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

6.2 Discussion on Design and Performance Provisions

The City has adopted the Standard Plans and Specifications for Public Works Construction (Greenbook), 2006 edition; the San Diego Regional Standard Drawings (SDRSD) 2006 Update; and the City-annotated SDRSD 2007 (included in Appendix C), as the referenced standard specifications and drawings for public services projects. The City also uses the Standard Special Provisions for Permit Construction, which are included in Appendix D. To address the components listed in Section 8.1 and as required by the WDRs, the City’s requirements for the design and construction of new, rehabilitated, and replaced sewer system facilities, including mains, tie-ins, service laterals, cleanout, manholes, and other system appurtenances, necessary to ensure the proper operation of the sewer system are summarized below. a) Design and Construction Standards and Specifications The requirements for the design and construction of new, rehabilitated, and replaced sewer system facilities, including mains, tie-ins, service laterals, cleanout, manholes, and other system appurtenances, are necessary to ensure the proper operation of the sewer system. The City requires that all public sewer mains within the City be constructed in accordance with the Greenbook, 2006 edition prepared by the American Public Works Association, the SDRSD 2006 Update, and the City-annotated SDRSD 2007. The documents include minimum design standards for sewer mains, sewer manholes, and sewer laterals, and general guidelines for common sewer rehabilitation options. The City also requires compliance with the Standard Special Provisions for Permit Construction, adopted in May 2008 which is included in Appendix C. The provisions include additional

Design and Performance Provisions

6-2

requirements for the design and construction of manholes, sewer laterals, and connections to existing mains. Design and construction considerations for wastewater facilities that the City considers non-standard, such as pump or lift stations, force mains, inverted siphons, internal sealing of existing sewers, treatment plants, outfall sewers, energy dissipaters, regulating devices, and/or flow measurement devices, are not included in the Greenbook or the SDRSDs and require prior approval from the City Engineer before design can begin. b) Inspecting and Testing The City may require compliance with the latest Greenbook standards for all cleaning and video inspections performed by contractors when retained for construction and installation of wastewater pipelines and manholes. The contractor performing work on the City’s sewer facilities is responsible for conducting a CCTV inspection for all new and rehabilitated sanitary sewer systems and other appurtenances and submitting a copy of the CCTV report and inspection documentation to the City to ensure compliance with City design and construction policies.

6.3 Conclusion

The requirements contained in the City’s current policies and procedures address the required components of the WDRs. However, the City will consider including the following provisions and requirements:

• Acceptable rehabilitation options for pipelines and manholes using various lining and coating methods

• A list of commonly used and City approved materials for rehabilitation options

• Plan and profile drawing submittals of wastewater facilities for the City’s review and approval

• Horizontal and vertical alignment standards for wastewater collection facilities

Chapter 7 Sanitary Sewer Overflow Response Plan This chapter of the SSMP provides a summary of the City’s SSORP. A copy of the City’s SSORP is included in Appendix E for reference.

7.1 Regulatory Requirements for Overflow Emergency Response Plan

The WDRs require that the City develop and implement an overflow emergency response plan which identifies measures to protect public health and the environment. At a minimum, the plan must include the following:

a) Proper notification procedures so that the primary responders and regulatory agencies are informed of all SSOs in a timely manner;

b) A program to ensure an appropriate response to all overflows;

c) 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;

d) Procedures to ensure that appropriate staff and contractor personnel are aware of and follow the Emergency Response Plan and are appropriately trained;

e) Procedures to address emergency operations, such as traffic and crowd control and other necessary response activities; and

f) 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.

7.2 Discussion of Overflow Emergency Response Plan

The City prepared the SSORP, which establishes the formal procedures for City staff to contain, correct, and clean up SSOs. The SSORP is intended to provide the City with a comprehensive document that includes components necessary for minimizing the effects of SSOs on the environment while protecting the public’s health and safety. The SSORP includes a strategy for the Sewer Maintenance Division to mobilize labor, material, tools, and equipment to contain, mitigate, and clean-up residuals from an SSO and correct or repair any condition which may cause or contribute to an SSO. The document provides the

SSORP

7-2

necessary guidelines for City staff to respond to an SSO event and contains the following elements:

• Introduction and Regulatory Requirements

• Sanitary Sewer Overflow Response Plan

• Public Advisory of Sewage Contamination Procedures

• SSO Reporting Requirements

• Training Requirements

• SSORP Updating Requirements

• Various Attachments

To address the components listed in Section 7.1 and as required by the WDRs, the following subsections provide a summary of the applicable procedures that are currently being evaluated for implementation and included in the SSORP. Further detailed descriptions of the policies and procedures as they pertain to responding to SSOs are included in the SSORP document included in Appendix E.

7.2.1 SSO Notification Procedures

The SSORP includes procedures for proper notification of the appropriate staff in a timely manner. Calls or complaints of possible or actual SSOs are received via telephone calls. All telephone calls are routed directly to the Wastewater Maintenance Division from either the City’s Customer Service or Coronado’s Police Dispatch center if the notification is received during non-business hours. The On-Call Duty staff member will respond to the notification or secure the appropriate back-up for response. Lift stations Alarms: The City’s Wastewater Maintenance staff is responsible for responding to any possible or actual SSO reported at any of the 16 lift stations. When an alarm at any of the pump stations is activated, the alarm signal is transmitted to the City’s alarm company, Security Signal Devices (SSD) Systems. SSD Systems notifies the Public Services Administration Department or the Coronado Police Department which alerts the On-Call Duty staff member or designated back-up during non-business hours, weekends, and City holidays. After receiving notification of an alarm activated at a lift station, the On-Call Duty staff member or the designated back-up will notify available crews to proceed to the lift station to assess the situation and resolve the problem. If the First Responder requires assistance, he or she will contact the appropriate personnel for assistance. Public Advisory: The County Department of Environmental Health has primary responsibility for determining when to post notices of polluted surface waters or ground surfaces that resulted from uncontrolled wastewater discharges from the City’s facilities. The County Department of Environmental Health may also make a determination and direct the City to post notices. Under the advisement of the Director of Public Services, Public Services staff may be directed to post warning signs prior to receiving direction from the County Department of Environmental Health. The postings do not necessarily prohibit the use of recreational areas, unless posted otherwise, but provide a warning of potential public health risks due to sewage contamination.


June 2009

7-3

The posting of notices shall be done as soon as practicable following the initial response to the overflow. Signs should be posted on either side of the point of entry where sewage entered the body of water or public facility and the nearest public access point to that body of water or public facility. Examples of signs are included in Attachment H of the SSORP, contained in Appendix E.

7.2.2 SSO Response

The City’s SSORP includes response priorities, safety, and overflow containment, correction, and clean-up measures for potential or actual SSOs of various types. Specific actions to be performed by Wastewater Maintenance Division staff and additional crews for public, private, and lift station SSOs are outlined and described. To summarize the SSO response procedures, a flow chart that illustrates the City’s emergency response procedures, including notification and request of additional resources as required in the event of a large SSO, is included in Figure 4-1 of the SSORP. Figure 4-1 offers a concise overview of the steps required to quickly respond to an actual or possible SSO event.

7.2.3 Procedures for Prompt Notification of Regulatory Agencies

The volume, impact, and location of an SSO determine the level of notification required to comply with City and regulatory requirements. Table 2-2 of the SSORP summarizes the officials and agencies to be notified of an SSO and under what conditions they are to be notified of an SSO. Attachment F of the SSORP includes a list of the specific names and telephone numbers of the individuals to be notified. The contact list should be updated as necessary and verified at least every six (6) months.

7.2.4 Training of Appropriate Staff and Contractor

Appropriate staff including Wastewater, Storm Water, and Solid Waste staff as well as the Sweeper Operator and Weekend Maintenance Worker III will participate in regularly scheduled training sessions to assist response crews in awareness of their responsibilities and executing their duties. The training sessions will be organized based on the latest SSORP as well as other reference materials. Training will also incorporate hands-on field demonstrations to insure the preparedness of all response personnel to all anticipated situations. Training and event participation will be documented and maintained. Currently, Wastewater Maintenance staff is encouraged to receive training through various vendors. Additionally, the City requires specific staff levels to receive training and certification through the California Water Environment Association (CWEA). All Wastewater Maintenance staff is required to have a Class B license and air and tank endorsements. Additional certification requirements may be imposed if deemed necessary by the SDRWQCB.

7.2.5 Emergency Procedures and Response Activities

Guidelines for traffic and crowd control to limit public access to areas potentially impacted by un-permitted discharges of sewage based on the various types of SSOs are also provided. Traffic and crowd control guidelines are included in Section 2.6 of the SSORP.

SSORP

7-4

Additional response activities are detailed in Chapter 3 of the SSORP and may include posting of notices, which shall be done as soon as practicable following the initial response to the overflow.

7.2.6 SSO Prevention and Containment

The City’s O&M Program (see Appendix B) documents the procedures the City follows to prevent SSOs. The City’s Preventive Maintenance Program includes the routine cleaning and inspection of the wastewater pipelines and specifically the HFMLs. The SSORP provides the guidance to facilitate and ensure the proper response to any type of potential SSO occurrence. The SSORP includes a strategy for the Wastewater Maintenance Division to mobilize labor, material, tools, and equipment to contain, mitigate, and clean-up residuals from an SSO and correct or repair any condition which may cause or contribute to an SSO. Appropriate mitigation measures to contain the SSO and recover spilled sewage to minimize the impact to the public or environment are included. Additionally, City staff will implement monitoring measures and perform a thorough assessment of the site for potential future SSOs and to prevent SSOs from re-occurring. The efforts serve to minimize and correct any adverse impact on the environment that may potentially result from an SSO.

Chapter 8 Fats, Oils, and Grease Control Program This chapter of the SSMP discusses the City’s FOG Control Program and includes identification of HFMLs and source control.

8.1 Regulatory Requirements for a FOG Control Program

To comply with the WDRs, the City is required to evaluate its service area to determine whether a FOG Control program is necessary. If deemed necessary, the City is required to develop and implement a FOG Control Program to effectively control the quantity of FOG that is discharged into the City’s sanitary sewer system. The FOG Control Program shall include the following as appropriate:

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

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;

c) The legal authority to prohibit discharges to the system and identify measures to prevent SSOs and blockages caused by FOG;

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

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

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

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.

8.2 Discussion of FOG Control Program

The City has prepared the FOG Control Program to document its current activities and facilitate the maximum beneficial public use for the City’s sanitary sewer system while preventing blockages of the sewer lines and reducing the adverse affects on sewage treatment operations resulting from discharges of FOG into the system. The City’s FOG Control Program documents the processes and procedures intended to reduce the quantity of FOG discharged into the City’s sanitary sewer system to achieve the goal of

FOG Control Program

8-2

minimizing SSOs due to excessive FOG. Elements of the City’s FOG Control Program include the following:





• Record Keeping and Reporting Requirements

• Permits and Enforcement

• Drawing Submittals


To address the components listed in Section 6.1 and as required by the WDRs, the following subsections provide a summary of the applicable FOG control procedures currently being implemented. The complete FOG Control Program is included in Appendix F.

8.2.1 Public Education Program

The primary focus of the City’s FOG Control Program has been on source control, with a concentrated effort on educating FSE staff on the negative impacts of putting FOG into the wastewater collection system. During the regularly performed site inspections, City staff provides informative and practical suggestions for reducing the quantity of FOG discharged into the City’s wastewater and storm drain system, engaging FSE staff in reducing FOG related SSOs. As necessary, the City will require an increase in the cleaning frequency of the pretreatment devices to ensure the FSE is in compliance with the City’s code and permitting requirements. To date, the City’s efforts to educate FSE staff has been effective in attaining the desired results from the FSEs.

8.2.2 Disposal of FOG

The FOG Control Program includes a description of BMPs, which include simple and effective practices that an FSE can implement to prevent and reduce the quantity of FOG discharged into the sanitary sewer system. Inspections performed by City staff provide the City an opportunity to reiterate the importance of limiting FOG discharge into the City’s wastewater collection system and reduce the potential of SSOs due to excessive FOG. The requirement for the pretreatment of wastewater flows generated at FSEs is included in the FOG Control Program and primarily includes the installation of grease removal devices as determined necessary by the City. The cleaning and removal of all accumulated grease is required to be performed by a licensed waste hauler with an approved license from an authorizing agency.


June 2009

8-3

8.2.3 Legal Authority to Prohibit Discharges

The City is required to prevent discharges of illicit and undesirable substances from entering the wastewater collection system. Illicit discharges include, but are not limited to, the release of I/I, storm water, chemical dumping, unauthorized debris and constituents, and cut roots. The City’s current legal authority to limit and prohibit FOG is established through its existing Municipal Codes and permitting procedures.

8.2.4 Requirements for Installation of Pretreatment Devices

The City’s FOG Control Program requires that each FSE be solely responsible for the proper operation, maintenance and repair of the approved grease removal equipment. Sizing and installation requirements for the grease removal equipment are approved by the City’s Director of Public Services or the Director’s designee. Cleaning and removal of accumulated grease is required to be performed by a licensed waste hauler with an approved license from an authorizing agency. To ensure proper disposal of the collected grease, the City requires that tracking logs be maintained by each FSE for a period of up to three (3) years and be made available to City Inspectors during scheduled and routine inspections. Additionally, the City’s Municipal Code includes provisions for requiring the installation of grease removal equipment. Discussed below is the City’s Municipal Code which addresses the requirements of grease removal equipment. Section 60.04.140, Permit Conditions, Special (Pretreatment), provides the City the authority to impose pretreatment requirements necessary to achieve specific discharge conditions including pretreatment levels acceptable to the Director of Public Services, target parameter concentrations, and categorical pretreatment standards in compliance with EPA and CWA requirements. Section 60.04.144, Permit Conditions, Special (Food Establishments), includes a summary of the type of equipment, devices and controls that may be required by the Director of Public Services. Specifically, it addresses the requirements for the installation and maintenance of the approved grease pretreatment device by the permittee. Section 60.04.150, Permit Conditions, Standard, is a summary of the standard conditions that are incorporated by reference into every discharge permit issued. The subsections provide the City with the authority to require sampling and monitoring facilities, revoke a discharge permit, require record retention, and require access to the permittee’s premises for sampling or for performing repairs. Section 60.04.150C, Sampling and Monitoring Facilities, provides the City the authority to require wastewater collection system users to install and maintain sewerage monitoring devices, determine the general requirements, and approve the installation of specific devices and proposed procedures for sampling and monitoring the wastes, wastewater flow, and facilities in compliance with the City’s requirements. Additionally, the section also allows the City to require the permittee to provide results of periodic measurements and analysis.

FOG Control Program

8-4

8.2.5 Facility Inspection

Implementation of the FOG Control Program will require all applicable FSEs to obtain and renew a Food Establishment Waste Discharge Permit. Although the requirements for compliance with the permit will vary among FSEs, generally each permit will require the FSE to meet the requirements for installation of FOG removal equipment, comply with applicable City policies, and pay all required fees. To determine whether the FSE is in compliance with the conditions of the Food Establishment Waste Discharge Permit, FOG Control Program, and the City’s Municipal Code, authorized personnel of the City will have the authority to inspect each FSE. Compliance with the FOG Control Program and City Municipal Code Section 60.04.150 requires that reasonable access to all parts of the FSE be made available when inspection and/or sampling of the wastewater is required.

8.2.6 Maintenance Schedule for High Frequency Maintenance Locations

The performance and scheduling of preventive maintenance activities is performed by the existing Wastewater Operations staff. The Preventive Maintenance Program includes a repetitive cleaning schedule for the areas that have been identified by City staff as HFMLs. The City’s HFMLs include pipe segments with high FOG and root concentrations. The pipe segments within the wastewater system identified as HFMLs are routinely cleaned on a monthly or bi-monthly basis.

8.2.7 Development and Implementation of Source Control Measures

Detailed information pertaining to the implementation of the City’s FOG Control Program and the source control measures for all sources of FOG discharged to the sanitary sewer system is included in the FOG Control Program which is included in Appendix F for reference.

Chapter 9 System Evaluation and Capacity Assurance Plan Identified as an element of the SSMP, the WDRs require each agency to prepare a System Evaluation and Capacity Assurance Plan. This section discusses the City’s capacity management measures to address the current and future capacity requirements of its collection system and the recommended capacity improvement projects.

9.1 Regulatory Requirement for System Evaluation and Capacity Assurance Plan

The WDRs require that the City prepare and implement a capital improvement plan 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 for 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 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 for the CIP 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 of the WDRs.

9.2 Discussion on System Evaluation and Capacity Assurance Plan

The City’s current Sewer Master Plan was completed by Poutney & Associates in 2000. The Sewer Master Plan evaluated the City’s sanitary sewer system, which included approximately 38 miles of gravity sewer ranging from 6 to 36 inches in diameter; 7 miles of force mains, ranging from 3 to 24 inches in diameter, and twelve (12) pump stations. The City is currently in the process of preparing an update to its Sewer Master Plan.

System Evaluation and Capacity Assurance Plan

9-2

The 2000 Sewer Master Plan presented an assessment of the hydraulic capacity of the existing major sewer pipelines located within the City service area. The capital improvement projects identified were considered to be required to correct system deficiencies under existing and build-out peak dry weather flow and peak wet weather flow conditions. Additionally, the sewer system was evaluated based on future designated land use to ensure that there was sufficient capacity in the sanitary sewer system under build-out conditions. A steady state hydraulic model was created in order to evaluate the capacity of the City’s gravity sewer system. The following subsections provide a brief summary of the modeled system, flow estimates, and evaluation criteria used for the City’s sewer system capacity evaluation to address the components listed above in Section 9.1 and as required by the WDRs. a) Evaluation The capacity assessment completed as part of the City’s Sewer Master Plan was based on hydraulic modeling of the City’s collection system under current and future estimated peak dry and wet weather design flows. The estimated average flows were determined based on the developed land use, planned development and wastewater generation factors for dry weather conditions. Peak dry weather flows were estimated by applying a dry weather peaking factor to the average flow based on the City of San Diego Sewer Design Guide (1994). Peak wet weather flows were estimated by applying a base infiltration rate of 10,000 gallons per day per mile of pipe (gpd/mi) to the peak dry weather flows. An infiltration rate of 30,000 gpd/mi was applied to pipes with deeper invert elevations. While this method is appropriate for basin infiltration, it does not account for surface flows entering the sewer system during rain events. In its update of the Sewer Master Plan, the City will address the peak wet weather flow conditions as required by the WDR. The Sewer Master Plan also did not appear to calibrate peak dry or wet weather flows during analysis. The system evaluation was performed to identify improvements necessary to adequately convey existing wastewater discharges and support future wastewater flows through build-out conditions. Table 9-1 summarizes the average, peak dry weather and peak wet weather flow estimates used in the model. The Sewer Master Plan addressed the dry and wet weather capacity issues for the system limits at the time. Additionally, the Sewer Master Plan included a summary of improvement projects and planned sewer facilities to improve hydraulic capacity and provide increased system reliability.

b) Design Criteria: The City’s 2000 Sewer Master Plan established design criteria for peak dry and wet weather flows, population density, per capita sewage generation, pipe criteria, and infiltration rates. The evaluation included a review of dry weather peak flow conditions and identified areas of the system that required modification and/or expansion. Recommendations for assessing current and future capacity requirements as well as a proposed schedule to complete the modifications were also included. Hydraulic Model Development The City’s system was divided into nine (9) separate gravity systems. A hydraulic model was developed for each of the nine study areas defined. Each study area was developed based upon the City’s prior studies and/or master planning efforts and available data. The model developed focused on gravity sewers of 8-inch diameter and larger. The City’s trunk sewers serve to collect and ultimately convey wastewater flows to the City of San Diego sewer system. The following provides a brief summary of the model created and the method used for developing the model. The wastewater collection system was modeled using “FLUSH”, a steady-state hydraulic model utilizing Manning’s equations to calculate the depth based upon inputted flows. The steady-state simulation utilized in the Sewer Master Plan was common practice at the time. The City’s system was modeled as a gravity system up to the point where flow entered a pump station. Pumped flows were entered into the model at the manhole where force mains ended. Force mains and pump stations were not included in the model system because “FLUSH” did not have the capability of analyzing these facilities. The Sewer Master Plan hydraulic analysis does not meet WDR criteria for evaluating system capacity, pump station storage, or pump station capacity during wet weather events. Existing and build-out average flows were determined for each subsystem and entered into the model from residential population and non-residential equivalent population projections based on available land use information, employee counts, and residential density. Peaking factors for dry weather and wet weather flows were assigned based on cumulative populations for each subsystem. Estimated Wastewater Generation Rates Estimates for wastewater generation rates are typically prepared using population and/or land use data. While it is also typical to express wastewater generation estimated in terms of Equivalent Dwelling Units, the Sewer Master Plan used equivalent population to generate wastewater flows. The following provides a summary of the methodology used to develop the wastewater generation rates in the Sewer Master Plan. The Sewer Master Plan estimated the wastewater generation using an equivalent population approach and a unit generation rate of 80 gallons per capita per day. Existing flows were calculated for the existing system based on land use from the City’s 1993 General Plan update. An equivalent population was assigned for each land use zone designation (residential,


9-4

commercial, resort, and hotel). Specific facility uses such as City Hall, police and fire stations, the hospital, and schools, were assigned typical per person unit flow rates. The unit flow rates were then converted to an equivalent population based on employee count and student enrollment. Future (2020) flows were calculated in a similar fashion to the existing flows, with future land use changes directed by the City Planning Department. Table 9-2 summarizes the unit generation rate factors that were used in the 2000 Sewer Master Plan.

Table 9-2 Unit Generation Rates and Population Densities

Land Use Unit Generation Rate Residential 80 gpd/person City Hall 15 gpd/employee Police Station 15 gpd/employee Fire Station 80 gpd/person

Hospital 171 gpd/bed 11 gpd/employee

Junior/High School 21 gpd/student Elementary School 16 gpd/student Land Use Population Density Residential (up to 12 DU/acre) 2.6 people/DU Residential (up to 47 DU/acre) 1.8 people/DU Commercial 43.9 people/net-acre Resort 1.25 people/room Hotel/Motel 1.0 people/room

System Capacity Analysis The Sewer Master Plan analyzed system capacity in the model based on the estimated peak wet weather flows for the existing and build-out conditions to identify capacity deficiencies and develop CIP projects. The existing and build-out scenarios were modeled under the peak dry and wet weather conditions and results were compared to threshold criteria to determine capacity deficiencies. The threshold criterion was depth-to-diameter ratios (d/D) at the design flow (Design Q) designated as d/D. This d/D ratio was identified in the design criteria for the existing and new/replaced pipes and was used to identify pipes needing improvement. For existing pipes, the City’s criteria allowed a maximum d/D = 1.0 for all pipe diameters. For new or replaced pipe, the City’s criteria allowed a maximum d/D = 0.75 for pipes with diameters greater than eighteen (18) inches and d/D = 0.50 for pipe with diameters eighteen (18) inches and less. Thus, pipes with d/D ratios exceeding the thresholds were identified as needing improvement.

c) Capacity Enhancement Measures Based on the threshold criteria discussed above, CIP projects for the replacement of gravity sewer pipelines were developed. The projects were assigned a priority based on the capacity, pipe condition, and proposed timeline for repair and/or replacement. A brief description of projects organized by priority is provided below.

Priority 1 replacements included pipes with existing flows that exceeded the pipe capacity. Various existing 10 and 12-inch pipes were recommended for upsizing to 15 and 18-inch pipes, respectively. Priority 1 pipe replacements were scheduled for replacement within five (5) years. Priority 2 pipes were those which were found to be cracked or shattered, have infiltration, or have root blockages obstructing flow, as shown during CCTV video review. Priority 2 pipe replacements were scheduled for replacement within six (6) to ten (10) years. Priority 3 pipes had major roots which would decrease capacity and cause debris accumulation. Priority 3 pipe replacements were scheduled for replacement within eleven (11) to fifteen (15) years. Priority 4 pipes had minor problems and were recommended for monitoring. Priority 4 pipes were scheduled for replacement within sixteen (16) to twenty (20) years.

As part of the Sewer Master Plan, the City’s force mains were evaluated based on age and condition of pipe, corrosion, and redundancy. The Sewer Master Plan identified 34,000 feet of new parallel force mains as Priority 1 projects. The Sewer Master Plan visually inspected 100 of the 710 existing manholes (approximately 14%). Fifteen (15) were identified as being in poor condition and an additional 20 were identified as requiring repair or replacement. A total of twenty-six (26) manholes were recommended for repair or replacements within five (5) years, as Priority 1 projects. An additional twelve (12) manholes were recommended for minor repairs to be completed within six (6) to ten (10) years, as Priority 2 projects. A visual site inspection was conducted for each of the City’s twelve (12) pump stations. As-builts and maintenance information also reviewed. The site inspections found that none of the pump stations had emergency backup power or emergency bypass connections (with the exception of the Glorietta Pump Station). The Glorietta Pump Station was found to have various deficiencies and recommended for the following upgrades: electrical service upgrade, wet well expansion, site piping consolidation, pump upgrades, odor control system improvements, and air release valve improvements. The Sewer Master Plan recommended, for each pump station, emergency electrical power connections and emergency portable generators. The Transbay Pump Station was also recommended for continued monitoring to verify station capacity. The City identified projects based on recommendations from the Sewer Master Plan. Projects that have been completed to date are listed in Table 9-3.

9.3 Recommendations for Capacity Assurance Plan

The City is currently updating its Sewer Master Plan based upon completed projects and newly identified projects, as discussed above. The City’s previous Sewer Master Plan did not take into account the current WDR criteria. Therefore, the City may want to consider the following actions in the next update of its Sewer Master Plan:

1. Perform a wastewater flow analysis focused on the Transbay Pump Station that analyzes available sewer metering data to confirm that the flow estimates used in the model reflect peak dry weather flow conditions and an appropriate design storm or wet weather event.

2. Develop a new dynamic hydraulic model to assess the capacity of the sanitary sewer system over an extended period. The model should include all pump stations and force mains.

3. Re-evaluate sewage generation criteria utilizing flow meter records and compare to land use and population forecasts available from the San Diego Association of Governments.

4. Apply industry standard (i.e. more conservative) trigger criteria and re-evaluate: (1) recommended projects; (2) potential capacity constraints within the wastewater collection system; and (3) the estimated required completion dates (in order to avoid a capacity related sewer system overflow).

5. Update the wastewater collection system capacity assessment, and consequently the Sewer Master Plan, at least every ten (10) years. The capacity assessment update should occur sooner if conditions arise that are expected to have significant capacity impacts on the system.

Chapter 10 Monitoring, Measurement, and Program Modifications This chapter of the SSMP discusses the parameters the City will utilize to track and monitor the progress of implementing elements of the SSMP, the effectiveness of the SSMP, and how the City intends to update and revise the SSMP to keep it current.

10.1 Regulatory Requirements for Monitoring, Measurement, and Program Modifications

The WDRs require the City to:

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

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

c) Assess the success of the Preventive Maintenance Program;

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

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

10.2 Discussion of Monitoring, Measurement, and Program Modifications

To date, the City has effectively managed and maintained information pertaining to the wastewater infrastructure by means of manually recording preventive maintenance activities and documenting notifications received regarding potential and actual SSO occurrences. The City has tracked performance measures through logs and reports including, but not limited to, the length of pipe cleaned and televised, the quantity, cause and location of stoppages, SSOs, and the scheduled maintenance of HFMLs. The City will continue to monitor the performance measures it currently tracks. To address the components listed in Section 11.1 and as required by the WDRs, the following subsections provide a summary of the procedures to be implemented to properly monitor program progress and implement necessary modifications.

10.2.1 Maintain Information Pertaining to SSMP Activities

The City has designated the Public Services Supervisor as the individual responsible for continually monitoring the SSMP provisions to ensure that the system is maintained in conformance with the document.

10.2.2 Monitor and Measure SSMP Elements

As the SSMP elements are implemented and evolve due to new technology, equipment, code changes, specific program enhancements, and the collection system’s rehabilitation through implementation of the CIP, the City will modify the elements. The Public Services Supervisor should identify and recommend updates to this SSMP as part of the City’s regular performance measurement assessments. The following performance parameters may be utilized, along with other typical industry and EPA performance indicators, to evaluate the City’s system:

1. Pipe age

2. O&M cost/mile/year

3. O&M staff/100 miles

4. Percent of system maintained, repaired, and/or replaced each year

5. Total annual percent cleaned

6. System cleaning cycle frequency

7. FOG program activities

8. Percent CCTV’d per year

9. I&I monitoring

10. Planning goals status

10.2.3 Assessment of Preventive Maintenance Program

The City’s O&M Program includes a summary of the City’s current procedures and practices as they pertain to O&M activities. On a regular basis, at least once every two (2) years, the City should evaluate the effectiveness of the O&M Program elements and staffing levels. Recommendations for appropriate adjustments and an implementation schedule should be developed. Implementation of any changes should be based on the urgency of the need, coordination with other program elements, and management approvals.

10.2.4 Update Program Elements

The City must review this SSMP on a regular basis and update the document with any significant changes. The SSMP must be reviewed, updated, and re-certified at least once every five (5) years. The City’s process should include distributing the SSMP to appropriate City staff for review, to ensure the most current legal authority, response plans, organizational charts, equipment lists, and contact/notification information are included. Once the City makes operational, maintenance, management, and administrative changes, the City may consider distributing the SSMP to other agencies to perform a peer review of the document. Once recommendations are incorporated into the document, the SSMP will be ready for public dissemination and ultimately for recertification by the City Council. The City is responsible for

10-3

maintaining the SSMP program as required by the SDRWQCB and will make the SSMP accessible to the public.

10.2.5 Identify and Illustrate SSO Trends

The City currently maintains a spreadsheet with information as to the emergency calls received reporting potential and/or actual SSOs. The City also submits SSO information on the CIWQS website, which is accessible to the public. The City will continue to document SSO trends. Additional information to be included in the documentation process is the frequency and approximate volume of the SSO. Finally, the City is efficiently and effectively implementing the measures to properly document and report any SSOs as required by the WDRs.

10.3 SSMP Modifications

The City must update the SSMP periodically to include current information, and modify the programs as necessary to ensure program effectiveness and continual compliance with the WDRs. Information that will be routinely updated includes, but is not limited to, contact names and phone numbers for City staff responsible for implementation of specific SSMP programs, staff on stand-by for SSO response, and approved contractors and vendors. As modifications to elements of this SSMP are deemed necessary, the City will implement them at the earliest practical time. However, changes will be officially made to this SSMP during the annual or bi-annual update to the document. A comprehensive SSMP update and recertification will occur every five (5) years or as necessary and will include any significant program changes.

Chapter 12 Public Education and Outreach The primary objective of a Public Education / Outreach Program is to increase public awareness of sanitary sewer system issues, to promote a sense of stewardship for the City’s system and facilitate its efforts towards the effective and efficient management, operation, and maintenance of the sanitary sewer system. This chapter of the SSMP discusses the City’s efforts to educate and inform the public and affected agencies regarding the proper use of the City’s sanitary sewer system.

12.1 Regulatory Requirements for Public Education and Outreach

The WDRs require the City to 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 City as the program is developed and implemented.

12.2 Discussion of Public Education and Outreach

The City’s Public Education and Outreach Program, established to communicate its efforts to comply with the WDRs and address the development and implementation of this SSMP, will serve to educate, inform, and engage key stakeholders. These include agencies served by the City’s sanitary sewer system or that may be affected by an SSO, and businesses, developers, contractors, vendors, and plumbers whose business could be impacted by specific requirements or elements of this SSMP. Through the City’s Director of Public Services and Executive team, the City should coordinate external communications between the City and the public regarding the development and implementation of this SSMP and the various elements. The Director of Public Services will be responsible for preparing and providing pertinent information for news releases, articles, and the website. Additionally, the Director of Public Services can work closely with the City Council, City departments, news media, the public and affected agencies to assist in promoting an open and frequent exchange of information necessary for the systematic and effective implementation of the various SSMP elements. The following includes a summary of the City’s efforts to educate, inform and engage the public’s support and participation in the proper utilization of the City’s sanitary sewer system, and to comply with the WDR requirements. City of Coronado Official Website The City’s current outreach efforts include maintaining a website (http://www.coronado.ca.us) to inform the public about City activities. The City’s website is an effective communication channel for providing alerts and news to the public. The main page of the website provides access to various City departments and includes links to information, important announcements, and

Public Education and Outreach

12-2

agendas for City Council meetings, as well as other key information for City residents. The City can utilize the website to publish its SSMP, providing the public the opportunity to view and offer input to the City as the SSMP elements are implemented. As well, the City can utilize the website to notify the public of important upcoming activities related to sewer system management. City of Coronado FOG Control Program The public outreach element included in the FOG Control Program includes a concentrated effort to educate FSE staff regarding proper management of FOG generated on site. During the site inspections, City staff provides information to FSE staff that results in the reduction of FOG discharged into the City’s wastewater collection system. Additionally, providing information through various forms of media is an effective way to engage the public in recognizing the importance of reducing the quantity of FOG introduced to the sanitary sewer system. Information can also be promulgated regarding the threat of excessive quantities of FOG as a cause of potential and actual SSOs. City of Coronado Sanitary Sewer Overflow Response Plan The SSORP includes a Public Advisory of Sewage Contamination Procedures chapter which includes a description of the action that City staff must take to limit public access to surface waters and other areas that may have been impacted by an SSO, as well as to notify the public of potential hazardous conditions. Examples of signs that may be posted to provide a warning of potential public health risk are included in Attachment H of the SSORP. Should additional notification of sewage contamination be deemed necessary, City staff is required to provide, in cooperation with the City’s Director of Public Services, further notices through the use of pre-scripted notices made available to the printed or electronic news media for immediate publication or airing, or by other measures, such as door hangers. Public Meetings Public meetings to discuss City-related issues are held regularly in the City Council Chambers, located at 1825 Strand Way. The City encourages residents to attend City Council meetings to become better informed about how the City works and to learn about various issues. The City Council meetings provide the residents and concerned citizens a forum to provide the Council with input on particular programs through the Oral Communication session portion of each City Council meeting. During the Oral Communication session, each person who wishes to address the City Council on an item not on the agenda may do so. Copies of the Council Agenda are made readily available to the public through the City’s website or the City Clerk's Office. The City Council is required to certify the completed SSMP during a public City Council meeting. Project specific meetings may also be convened with community leaders and other citizens to discuss the impacts, schedule and criteria of sewer related projects and efforts. These meetings give citizens a forum to learn about the City’s activities, voice their concerns, and receive clarification on a variety of issues. Often the project managers will arrange these meetings.

12.3 Public Education and Outreach Media

A variety of means exist to educate and inform the public regarding impacts to the City’s sanitary sewer system facilities. The following list identifies several forms of media available for the City to use to educate and inform the public:

• Bi-annual inserts in water and/or sewer bills;

• Press releases;

• Direct mailers;

• Door hangers;

• Brochures distributed at City locations and kiosks;

• Posters and flyers displayed prominently in public areas, such as on buses, libraries, recreational centers, and so on;

• Announcements and notices placed on the City’s web site;

• Advertisements placed in the City’s news letter; and

• Specific events held to educate the public on the effects of SSOs on the public and on environment; for example: an earth day fair, open house events, and other appropriate venues.

Examples of educational campaigns are included in Appendix G, which includes a flyer advertising that the drain is not a dump for FOG, a door hanger presented in both English and Spanish that can be left with residents, and best kitchen practices for businesses. Additionally, an example of text that may be included on a postcard and mailed to residents soon after a FOG related SSO has occurred is shown. This postcard would alert people to the effort involved in clearing a blockage and to reiterate not to put FOG down the drain. Translation services may be required and anticipated during any educational campaign. Educating the public to reduce FOG is an important task that should have a specific amount of time dedicated to its success. Investment up front in educating the public will reduce the financial expenditure in responding to and mitigating FOG related SSOs as they will be effectively reduced. Staff from the Public Services Department and other affected departments should work closely with the City’s Director of Public Services to develop appropriate messages and to determine on which media the messages should be disseminated. Additionally, the City intends to communicate on a regular basis with interested parties on the implementation and performance of this SSMP. The Public Education and Outreach Program will allow interested parties to provide input as the SSMP and its elements are developed and implemented.

1.0 INTRODUCTION

The City of Coronado (City) serves a population of approximately 26,500 customers within a 13.5 square mile area. The City’s wastewater collection system consists of approximately 45 miles of gravity and pressurized pipelines, approximately 750 manholes, and sixteen (16) pump stations. On average, the City, which is considered built-out, transfers approximately 3.2 million gallons per day (MGD) of sewage, including sewage flows from the two navy bases, the Naval Amphibious Base (NAB) and the Naval Air Station North Island (NASNI). Flows are conveyed to the City of San Diego's Metropolitan wastewater collection system, where they are conveyed to the Point Loma Wastewater Treatment Plant. As the City’s infrastructure ages over time, it is critical for the City to employ an Operation and Maintenance Program capable of sustaining adequate service to its customers via existing systems. The City’s Public Services Department is responsible for ensuring the proper and efficient operation of the wastewater collection system. It is tasked with implementing the regularly scheduled maintenance and cleaning of the City’s sewer pump stations and sewer pipe lines, responding to potential and/or actual sanitary sewer overflows (SSOs), closed circuit television (CCTV) inspection and assessment of the wastewater system, and facilitating a Fats, Oils and Grease (FOG) Control Program. This technical memorandum summarizes the City’s current procedures and practices as they pertain to the Operation and Maintenance (O&M) activities, and recommends changes to augment the City’s current activities to facilitate compliance with the Statewide General Waste Discharge Requirements (WDRs) for Sanitary Sewer System adopted as Order 2006-003 on May 2, 2006 and supplemented in the San Diego Region Order R9-2007-0005 adopted on February 14, 2007. This technical memorandum contains an evaluation of the elements affecting the O&M of the City’s wastewater collection system including, but not limited to, system inventory and mapping, inspection and assessment of the system including objective standards, the CIP project identification process, preventive maintenance procedures, and repair and rehabilitation procedures.

1.1 REGULATORY REQUIREMENT FOR OPERATION AND MAINTENANCE PROGRAM

The WDRs require all federal and state agencies, municipalities, counties, districts, and other public entities that own or operate a sanitary sewer system greater than one mile in length to comply with the elements of the WDRs. The WDRs serve to provide a unified statewide approach for reporting and tracking SSOs, establishing consistent and uniform requirements for developing and implementing a Sewer System Management Plan (SSMP), establishing consistency in reporting, and facilitating consistent enforcement for violations. The WDRs require that the City’s SSMP contain descriptive measures of the City’s O&M Program implemented by City staff to facilitate proper and efficient management and maintenance of the wastewater collection system and affected appurtenances. The WDRs



June 2009 2

require that the City’s SSMP include a description of each of the following components as they apply to the operation and maintenance activities pertinent to the wastewater collection system: • Maintenance of up-to-date sanitary sewer system map showing all gravity line segments

and manholes, pumping facilities, pressure pipes and valves, and applicable storm water conveyance facilities;

• Routine preventive operation and maintenance activities by staff and contractors. The Preventive Maintenance Program should have a system to document scheduled and conducted activities, such as work orders;

• Development of a rehabilitation and replacement plan to identify and prioritize system deficiencies and implement short-term and long-term rehabilitation actions to address each deficiency. The program should include regular visual and 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;

• Training, provided on a regular basis, for staff in sanitary sewer system operation and maintenance, and for repair contractors; and

• Inventory of equipment and replacement parts, including identification of critical replacement parts.

2.0 CITY’S OPERATION AND MAINTENANCE PROGRAM

The City’s current O & M procedures and practices address the following components:

• Inventory and Mapping of the Wastewater Collection System Assets • Preventive Maintenance Program • Sanitary Sewer Overflow Response Plan (SSORP) • Fats, Oils, and Grease (FOG) Control Program • Wastewater System Inspection and Assessment Program • Capital Improvement Program (CIP) Project Identification • Equipment and Replacement Part Inventories • Training and Safety Program

The following sections highlight the City’s O&M efforts and include recommendations that the City may implement to improve its O&M program.

2.1 INVENTORY AND MAPPING OF THE WASTEWATER COLLECTION SYSTEM

The location of the City‘s sewer pipes and associated appurtenances operated and maintained by the City are documented on laminated map books. The map books were prepared using as-built drawings information which is also included in the City’s geographic information system (GIS). The information contained in the GIS includes location information and pertinent facility attributes. Discrepancies between information contained on the map books and field conditions are manually documented on the map books by Wastewater Operations staff. Copies of the map book pages containing the noted discrepancies and corrections are provided to the GIS staff for updating of the relevant information. The City is currently in the process of updating their map books to reflect newly installed and realigned wastewater and storm water infrastructure including conveyance facilities, manholes, and pumping facilities. Completion of the conversion of the graphic information to the computerized mapping system, population of the GIS database, assignment of identifying labels to all pipeline segments and manholes, and establishment of a routine updating and maintenance procedure will enhance the City’s ability to effectively manage the system and implement an asset management program for the wastewater collection system. The City is working towards developing formal standard operating procedures for performing regular updates to the GIS information.

2.2 PREVENTIVE MAINTENANCE PROGRAM

To minimize and prevent system blockages and extend the system’s useful life, the City’s wastewater collection system requires frequent maintenance due to age, extended use, debris accumulation, and tree root intrusion. The City’s Preventive Maintenance Program primarily includes scheduled maintenance of wastewater facilities including sewer pump stations and routine cleaning of various wastewater collection system pipelines. The Preventive Maintenance program also includes routine root control, FOG control, and response to customer complaints. The following paragraphs describe the City’s current preventive maintenance procedures as they apply to the wastewater collection system. The scheduling and performance of maintenance and cleaning activities is currently performed by staff within the Wastewater Operations Division. Cleaning activities for the City’s sewer pipelines, wet wells, and pump stations are manually scheduled on an annual basis and completed by drainage basin. Work is assigned and performed and reports summarizing daily progress are generated by maintenance crews and submitted to the Public Services Supervisor to track progress and status of wastewater collection facilities. Daily progress reports and work-related forms are filed at the Public Services Yard for future access and reference. A wall map of the City, divided into basins and depicting the City’s wastewater collection system, is highlighted daily by the maintenance crews to reflect the cleaning completed. The map serves to provide City maintenance crews with a comprehensive view of the progress of the preventive maintenance efforts by basin.

2.2.1 Pump Station Maintenance

Maintenance activities are scheduled for pump stations and wet wells throughout the week. The pump stations and wet wells are inspected twice per week by Wastewater Operations’ staff members. Maintenance of each sewer pump station and wet well includes checking and/or recording the following pump station parameters:

• Air quality of underground stations, • Wet well liquid level, • Pump meter readings, • Pump settings, • Pump oil levels, • Alarm system, and • Condition of belts.

Other maintenance activities include routine cleaning of wet wells, draining water from mechanical seals, and greasing pump



June 2009 5

bearings. As the maintenance activities are performed, maintenance records are manually produced by staff. The records are submitted to the Public Services Supervisor and maintained by the Public Services Department.

2.2.2 System Cleaning

The City’s 45 miles of wastewater collection system are contained within six (6) drainage basins. The City’s cleaning efforts focus on one (1) drainage basin at a time in the direction of flow to convergence locations. The City’s Wastewater Operations staff work daily to eliminate potential pipe and manhole blockages and ensure relief valves and pump stations are operational. A two man crew (rotated among the five (5) Wastewater Operations’ staff members) is assigned to perform daily routine cleaning tasks of the City’s wastewater collection system, which includes gravity sewer and force mains and pump station wet wells. Additionally, crews clean high frequency maintenance locations on a monthly basis. These locations include areas with pipeline sags and areas identified as having excessive amounts of grease accumulation and/or concentrations of roots. The Transbay Pipeline, which traverses San Diego Bay and is considered to be a high risk facility as it conveys the City’s sewage flows to San Diego’s Metropolitan wastewater collection system, is on a three (3) year cleaning schedule and inspection schedule. The City is currently preparing to perform the hydraulic flushing and inspection of the pipeline. There are two (2) vacuum/jetter trucks and one confined space vehicle available to perform cleaning operations. The Wastewater Operations’ crews utilize one (1) combination vacuum/jetter vehicle and one (1) trailer mounted mechanical rodder. The sewers are typically cleaned by putting high pressure water jetting nozzles in the pipe and manually removing debris from the downstream manhole. Appurtenances are inserted at the downstream manhole to capture and remove debris. Debris removed from the sewer pipelines is decanted in a screened manhole located at the Public Services Yard. The liquid is discharged into the sewer and the debris is removed and relocated to a holding area in the Public Services Yard. The debris is transferred to a landfill as necessary. Progress ranges from 1,000 to 3,000 lineal feet per day, depending on the existing conditions, staffing available, and other assigned duties.

Cleaning of high frequency maintenance locations (HFMLs) is tracked and scheduled manually. Cleaning efforts are documented manually on daily reports. Documented information pertaining to sewer pipeline cleaning activities includes the section of pipe cleaned, lineal footage cleaned, the type of debris removed, names of staff performing the cleaning, and any additional pertinent comments.

2.2.3 Root Treatment

A component of the City’s cleaning efforts includes utilization of the City’s vacuum/jet rodder and routine chemical treatment to minimize the potential for SSOs due to root related problems. The City’s root treatment program is performed by a contractor retained by the City to perform routine chemical treatment of select portions of the City’s sanitary sewer system and includes the application of chemical root inhibitors to reduce or eliminate roots intruding into the pipes. As locations are identified for chemical treatment for root control, location information is recorded and treatment is performed by either the contractor or Wastewater Operations’ staff, using products maintained at the City Public Services Yard.

2.2.4 Odor Control

To prevent the potential side effect of strong odors migrating from the City’s wastewater facilities, the City’s preventive maintenance program includes the routine inspection of odor control systems at each pump station. Wastewater Operations staff inspect the City’s wastewater pump stations equipped with odor control beds and/or ventilation systems to prevent odor related issues from arising, identify potential odor causing problems, and ensure the odor control systems are operational and functioning properly. As well, Wastewater Operations staff check to ensure the facilities are sealed properly to reduce potentially bothersome odors from escaping.

2.3 SANITARY SEWER OVERFLOW RESPONSE PLAN

SSOs may occur due to blocked sewers, a restriction in the wastewater collection system, pipe failures, flows exceeding the capacity of the system, mechanical malfunctions, and other natural or man-made causes. The City recognizes the importance of protecting the health and safety of the public as well as the environment by preventing sewer flows from reaching surface waters and waters of the United States. This requires the implementation of procedures to minimize the impact of an SSO if one were to occur and comply with state regulations. In response to the potential occurrence of an SSO, the City prepared a SSORP which establishes the formal procedures for City staff to respond to, contain, correct, and clean up SSOs, and minimize the effects of SSOs on the environment while protecting the public’s health and safety. The City’s SSORP serves to supplement and be consistent with existing emergency plans and standard operating procedures currently implemented by the City. The overall plan facilitates coordination and mobilization of necessary equipment and personnel in an organized and efficient manner when responding to an SSO. The SSORP also incorporates the Monitoring



June 2009 7

and Reporting Procedures mandated by the WDRs. The primary goal in establishing an official SSORP is to ensure that City staff responds appropriately and efficiently to all known SSOs immediately.

2.4 FATS, OILS, AND GREASE CONTROL PROGRAM

Proper handling and disposal of waste containing excessive FOG quantities is important since it can accumulate in the wastewater collection system and eventually block collection pipes and sewer lines, resulting in backups and overflows on streets, properties, and potentially onto private property. Wastewater discharges containing high concentrations of FOG from food service establishments (FSEs) have been identified as a significant cause of blockages and overflows in the City’s wastewater collection system. Overflows of wastewater into the storm water collection system that ultimately reach our natural bodies of water could be greatly reduced by controlling the discharge of FOG into the wastewater collection system. SSOs are readily preventable by best management practices and proper maintenance at FSEs. The City’s proactive preventive maintenance procedures have been successful in minimizing the frequency of SSOs, facilitating the maximum beneficial public use of the city’s wastewater collection system while preventing blockages of sewer lines and pump stations, and reducing the adverse affects on sewage treatment operations resulting from discharges of FOG into the system. The City’s FOG Control Program establishes the general restrictions and requirements for FSEs that handle and discharge wastes containing FOG. It also provides information on various methods for effectively controlling and limiting the quantity of FOG discharged into the City’s wastewater collection system. In addition to requiring compliance with the City Municipal Code, policies, and the WDRs, the FOG Control Program serves as an additional enforcement mechanism to require accountability by the FSE for site specific maintenance and management of the facility.

2.5 WASTEWATER SYSTEM INSPECTION AND CONDITION ASSESSMENT PROGRAM

Regular and systematic inspection and assessment of sanitary sewer system facilities provides a means to monitor the condition of the facilities, the effectiveness of the maintenance operations, and a basis for identifying and scheduling capital improvements. As well, the overall assessment can be used to determine the funding required to repair, rehabilitate, and replace the City’s collection system as necessary, as well as to prioritize the allocation of funds and optimize the expenditure and efforts necessary to operate the sewer collection system.

2.5.1 System Inspection and Assessment

Approximately 100,000 lineal feet of the City’s wastewater system, including numerous manholes, were video inspected approximately ten (10) years ago, in 1998, by a contractor as part of updating the City’s Master Plan. Since the televising of the City’s wastewater collection



June 2009 8

system, City Wastewater Operations staff has performed CCTV inspections after an SSO occurrence, at the request of the Engineering Department or in specific areas following the annual scheduled cleaning. The City employs CCTV technology for the inspection of pipelines. With the use of the City’s one (1) CCTV vehicle, the City performs inspections of select sewer pipelines within the City’s wastewater collection system. The vehicle is equipped with Flexidata by Peer Point and can televise up to approximately 800 LF of pipe at a time. Manholes are visually inspected by City staff during the annual cleaning of the sewer pipelines and defects are noted in the log books. For wastewater collection system force mains, inspection and cleaning ports are being installed to facilitate access for inspection and assessment and cleaning purposes. Work orders for CCTV inspections are generated and tracked manually by Wastewater Operations staff. Progress is manually recorded by a staff member in a log book and utilized for recording, tracking, and reporting purposes. A copy of the map book is kept in the CCTV van and is highlighted to track progress.

2.5.2 Repair and Rehabilitation Projects

It is critical for the City to maintain a sewer replacement and rehabilitation program in order to sustain adequate service to its customers and maintain the condition and performance of the wastewater collection system. The City’s Wastewater Operations Division is responsible for performing various types of wastewater facility repairs and rehabilitation improvements. Repair and rehabilitation work performed by maintenance crews may include point repairs at cracks, joints, and service interfaces, repairing collapsing or broken sewer pipe, removing obstructions in the sewers that hinder cleaning operations, some video inspection and other related work. A rehabilitation and replacement plan serves to identify and prioritize system deficiencies and establish short- and long-term rehabilitation actions to address each deficiency. Pipeline replacement projects were identified and prioritized based on CCTV inspections performed in 1998. Since the CCTV inspection was performed, approximately five (5) segments per year have been replaced and have typically consisted of upsizing 6-inch to 8-inch pipelines. The Wastewater Operations staff is able to implement mitigation efforts and perform repairs for pipelines 6- to 8-inches in diameter to restore or replace failing wastewater collection sewer lines. Repairs for pipelines greater than 8-inches in diameter and repairs that require an extensive construction effort are either directed to the Engineering Division or performed by independent contractors retained by the City.

2.6 CIP PROJECT IDENTIFICATION

The City’s engineering staff, coupled with recommendations provided by Public Services’ Wastewater Operations’ staff, prioritizes pipeline replacements and rehabilitations to address critical issues including structural integrity, effectiveness in reducing infiltration and inflow, effect on flow capacity, and community impacts. Based on the results of the City’s 2000 Master Plan



June 2009 9

document, in conjunction with the results of the CCTV inspection efforts performed as part of the Master Plan and the CCTV inspections performed since the Master Plan was prepared, the City has prioritized the repair, rehabilitation, or replacement of the deficient sewer pipelines, pump stations, and associated appurtenances. The City prepares a two (2) year budget. Projects are identified from a master list of needs. For the upcoming budget cycles, City staff has prioritized the list of CIP projects for repair, rehabilitation, or replacement of the deficient wastewater facilities at risk of collapse or prone to more frequent blockages due to pipe defects. The priority list can be used to update and initiate capital improvement program projects. New projects are added to the list of CIP projects currently identified by the City to ensure the proper management and protection of infrastructure assets. The time schedule for implementing the short and long-term projects, plus a schedule for developing the funds needed for the capital improvement plan, is in the process of being updated.

2.7 EQUIPMENT AND REPLACEMENT PART INVENTORIES

The Wastewater Operations Division maintains an inventory of materials and equipment available for the necessary operation and maintenance activities of the City’s wastewater collection system and is included in the attachment to this memorandum. The list is maintained and manually updated on a regular basis by Wastewater Operations’ staff. As well, funds are reserved for scheduled repairs and replacement of materials and equipment necessary for ensuring the proper maintenance and operation of the wastewater collection system. The City’s maintenance vehicles and sanitary sewer system replacement parts are made readily accessible to operations staff. The replacement parts, maintained in the Public Services Yard, are for specific types of repairs performed by Wastewater Operations staff. Sufficient supplies are kept to quickly address various types of routine and emergency conditions that may occur. This minimizes the possibility of an overflow and restores service to the customer with minimal interruption. For repairs that extend beyond the City’s internal resource capabilities, the City retains the services of professional contractors.

2.8 TRAINING AND SAFETY PROGRAM

Prior to performing any work on City facilities, City Wastewater Operations staff is trained on the existence and the provisions of wastewater operation and maintenance policies, procedures, safety policies, and the equipment used. Training on the operation of City equipment includes primarily “on-the-job” training in conjunction with bi-weekly meetings to discuss safety issues and operating procedures. The Services Supervisor documents the training subject, duration and attendance. The Lead Pump Mechanic is required to receive Collection and Mechanical Technology certification through CWEA and hold a Class B California drivers license. Maintenance Workers II and Maintenance Workers III are required to hold a Class B California drivers license. The City provides at least two (2) opportunities a year for staff to attend training administered by



June 2009 10

outside training agencies. The Services Supervisor documents the type of training staff members receive, which includes:

1. Confined Space

2. Trenching and Shoring

3. Pumps

4. Basic Electricity

5. Hydraulics

6. Jetting Techniques

7. Various Safety Procedures As necessary and determined by appropriate managerial staff, training programs may also include supplemental technical training required to efficiently and safely perform specific job related duties.

3.0 DESIGN AND PERFORMANCE PROVISIONS

As new and rehabilitation projects that require the repair and replacement of aging infrastructure emerge, the City should apply comprehensive design guidelines and construction specifications for industry-accepted construction methods to ensure appropriate and consistent methods are implemented throughout the City. This section serves to summarize the relevant City policies, standard drawings, and applicable technical provisions currently utilized by the City to establish a reliable and safe wastewater collection system in compliance with the WDRs. The WDRs specifically require that the following components be addressed:

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

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

3.1 DISCUSSION OF REGULATORY DESIGN AND PERFORMANCE PROVISIONS

To address the requirements required by the WDRs, the following subsections provide a summary of the procedures currently being implemented. The standards follow industry accepted practices and apply to the design, repair, and replacement of new and existing sewer infrastructure.

a. Design and Construction Standards and Specifications

The City’s requirements for the design and construction of new, rehabilitated, and replacement sewer system facilities, including mains, tie-ins, service laterals, cleanouts, manholes, and other system appurtenances necessary to ensure the proper operation of the sewer system are included in the Standard Specifications for Public Works Construction (Greenbook) 2006 Edition, the San Diego Regional Standard Drawings (SDRSD) 2006 Update, the City-annotated SDRSD Drawings 2007 and the City of Coronado Standard Special Provisions for Permit Construction. Collectively the standards allow the City to require and enforce the proper construction and connections to the City’s collection system, and ensure access to City sewer pipelines for maintaining, inspecting, and repairing the system.

b. Inspecting and Testing The City requires compliance with the latest Greenbook standards for all cleaning, video inspections, and testing performed by contractors when retained for construction and installation of wastewater pipelines and manholes. The information provided by the contractor is subsequently reviewed by the City’s designated inspector to ensure compliance with design and construction policies. For unique projects, or projects not covered by the standard materials, specific inspection and testing requirements are developed by the engineer.

Chapter 1 Introduction Because Sanitary Sewer Overflows (SSOs) of various volumes may occur in spite of concerted prevention efforts, the City of Coronado (City) has prepared this Sanitary Sewer Overflow Response Plan (SSORP). SSOs may occur from blocked sewers, pipe failures, mechanical malfunctions, and other natural or man-made causes. City crews are constantly on alert and ready to respond upon notification and confirmation of an SSO. This SSORP establishes the formal procedures for City staff to respond to, contain, correct, and clean up SSOs, and it is intended to minimize the effects of SSOs on the environment while protecting the public’s health and safety. Chapter 1 provides an overview of the City’s wastewater collection system, the purpose and goals of the SSORP, the regulatory authority requiring this plan, an overview of this document’s organization, and definitions of terms contained in this document.

1.1 Wastewater Collection System Overview

The Wastewater Division is responsible for the maintenance of 16 sewer pump stations and more than 45 miles of underground sewer pipe line. On average, Coronado transfers 3.2 million gallons per day of sewage, including sewage from the Coronado Cays and all Navy bases, to the City of San Diego's Metropolitan wastewater conveyance system for treatment at the Point Loma Wastewater Treatment Plant.

1.2 Purpose and Objective

The City recognizes the importance of protecting the health and safety of the public as well as the environment by preventing sewer flows from reaching surface waters and waters of the United States. The City also understands the need to implement procedures to minimize the impact of an SSO, if one were to occur, and comply with the requirements of state regulations. The overall objective in establishing an official SSORP is to ensure that City staff immediately responds appropriately and efficiently to all known SSOs. The objectives of the SSORP can be summarized as:

• Protect public health and safety, and the environment;

• Minimize the effects of SSOs;

• Satisfy regulatory and discharge permit conditions;

• Protect private and public property;

• Protect City personnel; and

• Protect all City owned assets.

Introduction

1-2

This SSORP is intended to supplement and be consistent with existing emergency plans and standard operating procedures currently implemented by the City. The overall plan will facilitate coordination and mobilization of necessary facilities and personnel in an organized and efficient manner when responding to an SSO.

1.3 Organization of this SSORP

This document provides the necessary guidelines for City staff to respond to an SSO occurrence. This SSORP contains the following elements:

• Introduction;

• Sanitary Sewer Overflow Response Procedures;

• Public Advisory Of Sewage Contamination Procedures;

• SSO Reporting Requirements;

• Training and Safety Requirements;

• SSORP Updating Requirements; and

• Various Attachments.

1.4 Regulatory Requirements

The following regulatory requirements establish the impetus for the City to develop and follow procedures to minimize the potential for and impact of SSO occurrences. California Water Code Section 13271, California Code of Regulations: Section 13271 of the California Water Code, Title 23 of the California Code of Regulations, prohibits the discharge of sewage and hazardous material into the waters of the State and requires the proper notification of authorized agencies in the event of an SSO. Entities which do not properly follow the requirements of this section may be found guilty of a misdemeanor and punished by fine, imprisonment, or both. California Waste Discharge Requirements: On May 2, 2006, the State Water Resources Control Board adopted the Statewide General Waste Discharge Requirements (WDRs) for Sanitary Sewer Systems, Order No. 2006-0003. The WDRs are applicable to all federal and state agencies, municipalities, counties, districts, and other public entities that own or operate sanitary sewer systems greater than one (1) mile in length that collect and/or convey untreated or partially treated wastewater to publicly owned treatment facilities in the state of California. Specifically, the WDRs, as part of the Monitoring and Reporting Program and Order No. WQ 2008-0002 EXEC (adopted on February 20, 2008), require that the City establish monitoring, recordkeeping, reporting, and public notification requirements for SSOs, including on-line reporting requirements through the State’s California Integrated Water Quality System (CIWQS) web-site.

Clean Water Act, Section 1251 of Chapter 33 of the United States Code: In 1972, the Federal Congress enacted the Federal Water Pollution Control Act, commonly known as the Clean Water Act (CWA). The CWA prohibits the discharge of pollutants, including sewage, into public waters of the United States. The federal government has the authority to enforce compliance with the CWA via specific permits, such as National Pollutant Discharge Elimination System permits, as well as court actions such as administrative orders and consent decrees.

1.5 Definitions

Category 1 Sanitary Sewer Overflow: All discharges of sewage resulting from a failure in the City’s wastewater collection system that:

• Equals or exceeds 1,000 gallons; or

• Results in a discharge to a drainage channel and/or surface water; or

• Discharges to a storm drain and was not fully captured and returned to the wastewater collection system.

Category 2 Sanitary Sewer Overflow: All non-Category 1 SSO discharges of sewage resulting from a failure in the City’s wastewater collection system. First Responder: The City’s Wastewater Division staff member who is initially notified of a possible or actual SSO and arrives first at the reported location of the possible or actual SSO. Private Lateral Sewage Discharge: Sewage discharges that are caused by blockages or other problems within a privately owned lateral. Public Waters: Any body of water such as the ocean, bay, lake, pond, river, stream, or creek where there is the potential for human contact as defined by the County of San Diego Department of Environmental Health (DEH). Sanitary Sewer Overflow: A sanitary sewer overflow (SSO) is any overflow, spill, release, discharge, or diversion of sewage from a wastewater collection system. SSOs include:

• Release of untreated or partially treated sewage that reach waters of the United States;

• Release of untreated or partially treated sewage that does not reach waters of the United States; and

• Sewage backups into buildings and private property that are caused by blockages or flow conditions in a wastewater collection system, other than a building lateral. Sewage backups into buildings caused by a blockage or other malfunction of a building lateral that is privately owned is an SSO when sewage is discharged off of a private property into public streets, storm drains, or waters of the State.

Sewage: Any liquid waste and water borne solid waste resulting from residential, commercial, industrial, or institutional activities or uses.

Introduction

1-4

Standby Person: A designated Wastewater Division staff member who is on call to perform his or her assigned duties outside of his or her regularly assigned working shift. Surface Waters: All permanent and intermittent drainage ways, lakes, and reservoirs, either public or private, which are not man-made for the treatment of municipal, agricultural, or industrial waste, and wholly or partially within the boundaries of the City. SSOs to storm drains tributary to surface waters shall be reported as discharges to surface waters. Untreated or Partially Treated Wastewater: Any volume of sewage discharged from the wastewater collection system upstream of a wastewater treatment plant. Wastewater Collection System: Any system of pipes, pump stations, sewer lines, etc., used to collect and convey sewage to a treatment plant. Temporary storage and conveyance facilities (such as vaults, temporary piping, construction trenches, wet wells, impoundments, tanks, high-lines, etc.) are considered to be part of the sanitary sewer system, and discharges of sewage to these facilities are not SSOs. Waters of the United States: All waters of the United States as defined in the Code of Federal Regulations, Volume 40, Section 122.2 (40 CFR 122.2) such as navigable waters, rivers, streams, lakes, natural ponds, wetlands, etc., including tributaries to traditional navigable waters.

Chapter 2 SSO Response Procedures SSOs are caused by a blockage or a restriction in the wastewater collection system, pipe failures, flows exceeding the capacity of the system, and other natural or man-made causes. In the event of an SSO, the City’s Public Services staff must respond and be prepared to:

• Contain the SSO;

• Mitigate the overflow;

• Clean up the contaminated area; and

• Notify the appropriate authorities.

Public Services staff from the Wastewater and Storm Water Divisions is primarily responsible for responding to potential or actual SSOs. This section presents a strategy for the City’s Wastewater Division and Storm Wwater Division staff to mobilize labor, materials, tools, and equipment to contain, mitigate, and clean-up residuals from a sewer overflow and correct or repair any condition which may cause or contribute to a sewage discharge. This plan is applicable to a wide range of potential system failures that could create an SSO. Figure 2-1 summarizes the process presented in this chapter and offers a concise overview of the following steps required to quickly respond to an actual or possible SSO event.

2.1 Receiving Information about a Possible SSO

An SSO may be detected by City employees or the public. Suspicious circumstances, such as foul odors, backed up plumbing, unusual flooding, unusually low flows entering a pump station or treatment plant, and so on, may also indicate the possibility of an actual or impending SSO. This section describes how the City’s Wastewater Division staff is notified of possible SSOs.

2.1.1 Notifications of Possible SSOs

Notifications of possible SSOs may be received via telephone calls. Calls or complaints received via telephone for actual or possible SSOs are routed to the Wastewater Maintenance staff or available response crews. If a designated Wastewater Maintenance staff member is not available or non-responsive, then the designated backup person is notified. Figure 2-2 shows how a possible SSO will be reported to the designated Wastewater Maintenance staff member.

Figure 2-2 Process for Alerting Staff of a Possible Sanitary Sewer Overflow

As illustrated in Figure 2-2, notification of a potential or actual SSO will be routed directly to a Wastewater Maintenance staff member during normal business hours. During non-business hours, weekends, and on designated City holidays, calls will be received by the City of Coronado Police Dispatch Center and forwarded to the On-Call Public Services’ Duty staff member who will then contact available and qualified SSO response staff members. Upon receipt of a notification of a potential SSO, the Wastewater Maintenance staff member or the designated backup will obtain as much information as possible from the reporting entity. The relevant information that should be collected includes:

• Time and date the call/SSO report was received;

• Specific location (address, cross streets, etc.);

• Description of problem;

• Time the possible SSO was noticed by the caller;

• Caller’s name and telephone number;

• Observations of the caller (e.g. odor, duration, back or front of property, etc.); and

• Other relevant information that will enable the responding City staff personnel and crews, if required, to quickly locate, assess, contain, and relieve the SSO.

The Sewer Overflow Report form in Attachment A is used by the Wastewater Maintenance staff member or designated backup to capture the relevant information needed to respond to a report of a possible SSO as well as being useful for initiating the work order assignment.

2.1.2 Wastewater Maintenance Personnel Notifications of Possible SSOs

Possible and actual SSOs detected by Wastewater Maintenance personnel in the course of their normal duties are reported immediately to the Public Services Supervisor or designated backup. Personnel on-site observing the SSO should begin efforts to contain and minimize the effects of the SSO as further described in sub-section 2.5 below.

2.1.3 Pump Station Alarm Notifications of Possible SSOs

The City’s sixteen (16) sewer pump stations are equipped with alarm systems. Each pump station transmits signals directly to Security Signal Device (SSD) Systems, the alarm company contracted by the City, during business and non-business hours. An alarm signal is transmitted due to any of the following conditions:

• Power failure;

• High water level in the wetwell;

• Low water level in the wetwell; and/or

• Loss of echo

Upon receipt of an alarm signal, SSD Systems will notify Public Services or the police department who will dispatch available crew. The Wastewater Maintenance staff member or the designated backup will proceed to the pump station to assess the situation and resolve the problem. If the First Responder requires assistance, he will contact the appropriate personnel for assistance. In the event an emergency bypass procedure is required to prevent a potential SSO occurrence at a pump station, City staff will implement the bypass procedure developed specifically for the pump station and described in detail in the City’s Standard Operating Procedures for Emergency Pump Station Bypass.

2.2 First Responder Responsibilities

Based on the information provided during the notification of a possible or actual SSO, the Wastewater Maintenance staff member or the designated backup shall proceed to the SSO location to assess the cause and extent of the SSO. The City staff person to arrive first at the location is considered the First Responder. The First Responder will determine whether to direct


June 2009

2-5

additional Wastewater Maintenance staff, other City personnel, and/or approved contractors to the SSO location if the SSO cannot be fully contained or recovered or if it has reached public waters. The information obtained during the initial notification of a possible SSO may warrant the First Responder, in his best professional judgment, to dispatch Wastewater Maintenance staff or other City personnel before proceeding to the reported SSO location. It is the responsibility of the First Responder to protect the health and safety of the public by mitigating the impacts of the SSO to the maximum extent possible. Areas where public contact with sewage is possible shall be isolated using barricades, signs, or other effective means. Upon determining if the SSO originated in the City’s jurisdiction, the First Responder will perform the following:

• Implement efforts to stop or contain the overflow;

• Determine the cause of the SSO, e.g. sewer line blockage, or pipeline break, etc.;

• Obtain photographic documentation before and after overflow containment;

• Identify and request, if necessary, additional personnel, materials, and equipment necessary to minimize, contain, or isolate the impact of the SSO; and

• Control public access to affected area.

If the First Responder determines the SSO is not within the City’s jurisdiction, he or she should notify the responsible agency, homeowner, or business owner to respond to the overflow. If the SSO poses an imminent danger to the public, public health, property, or to public waterways of the United States, then the First Responder should take prudent emergency actions, as described further in the following sections, to mitigate the SSO until staff of the responsible party arrives. Figure 2-1 offers a concise overview of the steps required to respond to an actual or possible SSO occurrence. If the First Responder cannot locate the SSO or the reported problem, he or she shall attempt to obtain additional information from the incident reporter or Police Dispatch Operator to clarify reported data and to locate the problem. If the SSO or reported problem still cannot be located, the First Responder shall check the system for normal flows, advise the Police Dispatch Operator of the non-condition, remain at the location for a reasonable period of time, and prepare the final field report.

2.3 Dispatch of Crew(s) to SSO Location

Failure of any element within the wastewater collection system that threatens or causes an SSO triggers an immediate response to isolate and correct the problem. City Wastewater Maintenance Division crews and equipment are stationed at the City Public Services Yard, from where they are dispatched. The equipment is available 24-hours a day. An On-Call Public Services Duty Lead is placed on “standby” to receive notification from the Police Dispatch Center of an actual or potential SSO occurrence and notify available and qualified staff to respond to any site of the reported SSO. Also, additional City maintenance personnel are available in case additional resources are necessary. Attachment B contains the names and rotational schedule for the City’s “standby” staff. Also listed are the telephone numbers for the


2-6

Duty Phone and Duty Pager and additional instructions to ensure the telephone and pager are properly exchanged between the staff. Attachment C contains the names and contact information of the Public Services staff that may be contacted to respond to an SSO occurrence. All departments that may be required to provide resources in the event of an SSO should ensure that standby lists are prepared and distributed to all affected departments to facilitate communications as necessary. Standby lists for each department should be updated on a routine basis. All employees dispatched to an SSO location shall proceed immediately to the site. Overflows within the City’s jurisdiction that enter into areas outside the City’s authority will continue to be contained and the affected agency will be notified of the SSO to ensure proper cleaning and notifications are completed.

2.4 Requesting Additional Resources

If the First Responder determines that notification of additional staff beyond the available SSO response crews is required and/or City approved contractors are necessary to fully contain and recover the overflow, the First Responder or designated backup will mobilize the additional resources necessary. The City has access to additional resources from its own staff, as well as from outside on-call contractors who can be mobilized in case of an emergency or major SSOs. The list of City-approved contractors is provided in Attachment D.

2.5 Overflow Containment, Correction, and Clean-up

This section describes specific actions to be performed by Public Services staff members and additional crews responding during an SSO. The objectives of the following actions are to:

• Protect public health, the environment, and property from SSOs and restore the surrounding area to its original condition;

• Contain the sewage discharged to the maximum extent possible and prevent the discharge of sewage into surface waters;

• Establish perimeters and control zones with cones, barricades, sign postings, caution tape, vehicles, and/or terrain;

• Promptly notify regulatory agencies of preliminary SSO information and potential impacts as appropriate;

• Restore normal operating conditions of the wastewater collection system; and

• Minimize the City’s exposure to any regulatory agency penalties and fines.

Under most circumstances, the City will oversee, manage, and perform the tasks necessary to properly and effectively correct, contain, and clean up SSOs. The City shall respond with its own staff, equipment, and/or contractors. These personnel have the skill and experience to respond


June 2009

2-7

rapidly and in the most appropriate manner. Implementation of rapid and temporary SSO response measures is critical to controlling and mitigating an SSO. Therefore, it is important that temporary actions to divert flows and fix the problem do not create sewer system back-ups or additional problems elsewhere in the system. The SSO Response Flowchart shown in Figure 2-1 above illustrates emergency response procedures including notification and request of additional resources as required in the event of a large SSO.

2.5.1 Initial Measures and Containment

Minimizing the impacts to the public and environment are essential functions the First Responder must consider when responding to an SSO. The First Responder shall:

• Initiate measures to stop and contain the overflowing sewage and recover as much spilled sewage as possible;

• Determine the immediate destination of the overflow (e.g. street, curb, gutter, storm drain, drainage channel, creek bed, body of water, etc.);

• Identify and request, if necessary, assistance or additional resources (materials and equipment) to contain or isolate the overflow;

• Take immediate steps to contain the overflow (e.g. block storm drain, recover sewage with a vacuum truck, dig or construct a containment pond, divert flow into a downstream manhole, etc.); and

• Restore wastewater collection system to normal operating conditions if possible.

2.5.2 Additional Measures for Prolonged Overflow Conditions

In the event of a prolonged sewer line blockage or sewer line collapse, the responding City crew shall establish a portable by-pass pumping operation around the obstruction, continuously or periodically monitor the by-pass pumping operation, and perform emergency repairs to stop the overflow. Table 2-1 can be used as a guide to selecting the appropriate pump.

2.5.3 Correction of SSO Cause

Once the SSO has been contained efforts to correct the cause of the SSO should commence. These efforts may involve, but not be limited to, removing the pipe blockage by flushing or rodding, repairing a damaged pipeline or manhole, and manually operating pump station controls. Care must be taken to prevent additional SSOs from occurring as a result of the corrective action taken to resolve the identified problem.

2.5.4 Clean-up

All SSO sites must be thoroughly cleaned as soon as possible after an overflow. No readily identifiable residue (e.g., sewage solids, papers, plastics, etc.) is to remain. Clean-up of all SSOs will be handled according to the following procedures:

• The SSO site must be secured to prevent contact by members of the public until the site has been thoroughly cleaned;

• Where practical, the area shall be thoroughly flushed and cleaned of any sewage or wash-down water using high-pressure water hose or vactor truck; wash-down water shall be contained and recovered; solids and debris shall be flushed, swept, raked, or picked-up by hand, and hauled away for proper disposal;

• Where appropriate (typically in areas with hard surfaces), areas that came in contact with the sewage shall be disinfected and deodorized; proper contact time for proper disinfection must be ensured;

• Where sewage has resulted in ponding, the pond must be pumped dry and the residue removed and disposed of properly; and

• If sewage has discharged into a body of water that may contain fish or other aquatic life, disinfection will not be performed and the appropriate agency will be contacted.

2.6 Traffic and Crowd Control

The purpose of traffic and crowd control is to limit public access to areas potentially impacted by discharges of sewage. The following traffic and crowd control recommendations may be used as a guide for the various types of SSOs. All traffic control setups shall conform to the appropriate standards and criteria to ensure the safety of the crews and vehicles.

2.6.1 Category 2 SSOs

Small SSO (Up to 1,000 gallons) • Set up cones to direct traffic away from spill area; and

• Use City personnel to control traffic and pedestrians.


June 2009

2-9

2.6.2 Category 1 SSOs

Medium SSO (1,000 to 10,000 gallons) • Perform lane closures as necessary;

• Place proper signage for any lane closures and contaminated area signs;

• Close affected entrances or exits from public and private facilities; and

• Place caution tape and barricades to protect pedestrians from contaminated area.

Large SSO (greater than 10,000 gallons) • Assess spill situation;

• Inform City Police Department of any law enforcement assistance necessary for roadway closures and traffic control;

• Delegate responsibility to County Health Department of informing public of hazards;

• Place signage to inform public of potential hazards to public health and safety; and

• Block public access to hazard using barricades, cones, and caution tape.

2.7 Preliminary Assessment of Damage to Private and Public Property

Initial assessment of the SSO site is performed by the First Responder, who is a Wastewater Maintenance staff member or the designated backup person. The First Responder will determine whether the SSO originated from the City’s collection system or a private business or residence. Once the source of the SSO is determined, containment and cleanup procedures are executed, and a Sewer Overflow Report (see Attachment A) will be completed. Wastewater Maintenance staff members shall determine if CCTV inspection of the sewer main shall be performed to determine the potential cause of SSO and the condition of the pipe or manhole at the location of the overflow.

2.7.1 Public Source SSO

If it is determined that the source of the SSO is from the City’s wastewater collection system, containment and cleanup procedures are executed to prevent the SSO from reaching adjacent private properties, local water bodies, and the storm drain system. Once the SSO is contained and cleaned, City staff will complete the Sewer Overflow Report and notify the appropriate agencies. If it is determined that the SSO has reached a private residence or business, the SSO is reported to the Services Supervisor or available supervisor prior to Wastewater Division personnel leaving the site. A Damage Report to Private Property (see Attachment E) is completed and attached with the Sewer Overflow Report to be forwarded to the Services


2-10

Supervisor. Photographs and/or video footage should be taken of the overflow and area impacted by the SSO. Photographs and/or video footage should be filed with the Sanitary Sewer Overflow Field Report.

2.7.2 Private Source SSO

If it is determined that the source of the SSO is from a sewer lateral, the responding Public Services staff and crews will use discretion in assisting the property owner/occupant as reasonably as they can. City’s Public Services staff is cautioned that the City and the responding staff and crews may be liable for further damages inflicted to private property during such assistance. If City’s Public Services staff and crews enter private property, it should be with the expressed permission of the owner/occupant of the property. Staff is directed to take appropriate still photographs and video footage, if possible, of the surrounding and impacted area in order to thoroughly document the nature and extent of the impacts. Photographs and/or video footage should be filed with the Sanitary Sewer Overflow Field Report. In the event that flow from an SSO originating from a sewer lateral extended into the public right-of-way, City staff will execute containment and cleanup procedures at the expense of the property owner to prevent the SSO from reaching adjacent private properties, local water bodies, and the storm drain system. Once the SSO is contained and cleaned, staff will complete the Sewer Overflow Report and submit it to the Services Supervisor. Staff is directed to take appropriate still photographs and video footage, if possible, of the surrounding and impacted area in order to thoroughly document the nature and extent of the impacts. Photographs and/or video footage should be filed with the Sewer Overflow Report and saved in the I/Divisions/SSO folder.

2.8 Notification Requirements

The volume, impact, and location of an SSO determine the level of notifications required to comply with City and regulatory requirements. Table 2-2 provides a summary of the officials and agencies who should be informed of an SSO as soon as practicable without impeding containment or other emergency response measures. Attachment F lists the specific names and numbers of the individuals holding these positions. The City is not required to send reports to the San Diego Regional Water Quality Control Board; this reporting is now achieved using the web-based on-line SSO reporting system, CIWQS, which is further described in Chapter 4.0 below.

2.9 Monitoring and Mitigation

The First Responder who confirmed the SSO must ensure that the provisions of this SSORP and other directives are met. City staff shall conduct an assessment of the impacts following an SSO. Appropriate mitigation and monitoring measures shall be implemented following the assessment to monitor the site for potential future SSOs and to prevent SSOs from re-occurring. CCTV inspections shall be scheduled subsequent to an SSO occurrence to ensure the problem has been resolved and to identify any additional potential problems that may require immediate resolution.

2.10 SSO Documentation

Documenting SSOs and their causes provides information for: • Management for performance measurement and decision-making;

• Regulators to meet established reporting requirements;

• Planning future maintenance and repair activities;

• Engineering determinations regarding capacity, rehabilitation, or replacement; and

• Reference for historical performance or claims.

The First Responder shall ensure that the SSO is properly investigated and documented. Information compiled during the investigation of the SSO shall be recorded on the Sanitary Sewer Overflow Report as shown in Attachment A. Copies of supporting information shall be compiled. The minimum information required from the investigation is:

• Cause of SSO;

• Volume of SSO including volume released and volume recovered;

• Location of point of discharge, including Global Positioning System (GPS) coordinates;

• Ultimate destination of the SSO;

• Impact and extent of impact;

• Estimated start time of SSO;

• Time City received notification of SSO;

• Arrival time of crew(s) and time to correct the SSO;

• End time of SSO;

• Water body impacted and results of bacteriological monitoring, if applicable;

• Actions taken to mitigate the SSO; and

• Notifications to regulators and others.

A variety of approaches exists for estimating SSO volumes. Attachment G provides guidance on estimating the volume of sewage that escaped from the wastewater collection system and the amount of sewage recovered. Once the results of the SSO investigation are completely documented on the Sanitary Sewer Overflow Report, a copy of the form shall be provided to the Public Services Supervisor. The Public Services Supervisor shall follow up, in person or by telephone, with the person(s) initially reporting the SSO. The cause of the SSO and its resolution will be disclosed.


June 2009

Chapter 3 Public Advisory of Sewage Contamination Procedures This chapter describes the action the City must take to limit public access to surface waters and other areas potentially impacted by SSOs originating from the wastewater collection system. The DEH has primary responsibility for determining when to post notices of polluted surface waters or ground surfaces that resulted from uncontrolled wastewater discharges from City facilities. The DEH may also make a determination and direct the City to post notices. Under the advisement of the Director of Public Service, Public Services staff may be directed to place warning signs without the direction of the DEH. The postings do not necessarily prohibit the use of recreational areas, unless posted otherwise, but provide a warning of potential public health risks due to sewage contamination. The posting of notices shall be done as soon as practicable following the initial response to the overflow. Signs should be posted on either side of the point of entry where sewage entered the body of water or public facility as well as at the nearest public access point to that body of water or public facility. Examples of signs are included in Attachment H. Staff shall regularly inspect the posted notices and replace any missing or damaged warning signs. Posted notices shall not be removed until it is determined that the threat to public health and safety is eliminated, or at the direction of the DEH. Should additional notification of sewage contamination be deemed necessary, DEH will distribute NEWS RELEASES and advise the public of the affected areas.



June 2009

Chapter 4 SSO Reporting Requirements City staff shall monitor and report SSOs, regardless of size and recovery, originating from the City’s wastewater collection system. The City is also required to report any known SSOs that occur on private property from private laterals. This chapter details the reporting procedures necessary to comply with State Water Resources Control Board and City requirements.

4.1 SSO Identification, Tracking, and Logging

A work order must be created to track and monitor each SSO event. Using a completed Sewer Overflow Report form (Attachment A), the Public Services Supervisor or designee can create the work order and enter the necessary data from the forms. All forms, documentation, and monitoring results should be kept with the work order.

4.2 SSO Category Classification

SSOs are divided into three categories:

• Category 1 Sanitary Sewer Overflow: All discharges of sewage resulting from a failure in the City’s wastewater collection system that:

o Equals or exceeds 1,000 gallons; or

o Results in a discharge to a drainage channel and/or surface water; or

o Discharges to a storm drain and was not fully captured and returned to the wastewater collection system.

• Category 2 Sanitary Sewer Overflow: All non-Category 1 SSO discharges of sewage resulting from a failure in the City’s wastewater collection system.

• Private Lateral Sewage Discharge: Sewage discharges that are caused by blockages or other problems within a privately owned lateral.

Figure 4-1 shows a flow chart that will guide City staff in determining the category classification of an SSO, and the reporting requirements that are necessary.

4.3 On-Line Reporting Requirements

As of January 2, 2007, the WDR requires that the City report SSOs using CIWQS, an internet-based reporting system. This section describes the reporting procedures.

June 2009

4-3

4.3.1 Reporting Authority and Access

At a minimum, the City is required to have one (1) Legally Responsible Official (LRO) who is registered with the State of California to officially sign and certify SSO reports submitted via the CIWQS web-site. Currently, the Director of Public Services is identified as the City’s LRO. The City has identified the Public Services Supervisor as an additional LRO to act as a backup. The City has identified Data Submitters. These are individuals registered with the State to enter SSO data, create and edit SSO reports, and review data. Data Submitters cannot certify reports. Data Submitters are typically the First Responders to an SSO location, or the person who collects the SSO data for reporting. The City’s Management Assistant has been identified as a Data Submitter and can identify and register as many Data Submitters as deemed necessary. Each Agency is assigned a unique Waste Discharge Identification Number. The City of Coronado’s number is WDID #9SSO10647. All LROs and Data Submitters receive a unique logon and password. This information should be guarded and protected. If an authorized user suspects his or her logon and password have been lost, stolen, or otherwise compromised, that person shall contact the State Water Resources Control Board via the CIWQS help desk at 866-792-4977.

4.3.2 Mandatory Information to Report via CIWQS

Specific mandatory information must be included for each SSO report submitted via CIWQS, prior to finalizing and certifying an SSO report. The following information is required for all Category 2 SSOs:

1. Location of SSO using GPS coordinates;

2. Regional Water Board 9;

3. San Diego County;

4. Whether the SSO entered a drainage channel and/or surface water;

5. Whether the SSO was discharged into a storm drain pipe that was not fully captured and returned to the wastewater collection system;

6. Estimated SSO volume in gallons;

7. SSO source (e.g. manhole, cleanout, pipeline, etc.);

8. SSO cause (e.g. mainline blockage, roots, grease, etc.);

9. Time of SSO notification or discovery;

10. Estimated operator arrival time;

11. SSO destination; and

12. Estimated SSO end time.

SSO Reporting Requirements

1. All information listed for Category 2 SSOs;

2. Identification of sewage discharge as a private lateral sewage discharge; and

3. Responsible party contact information, if known.

The CIWQS reporting requirements are not in lieu of other reporting requirements. The City must also perform Regional Board reporting requirements, the Governor’s Office of Emergency Services reporting, and notifications to the DEH. Once the data is properly entered into the CIWQS database, and the SSO investigation is complete, the SSO report must be certified by the LRO according to the timeframe included in Table 4-1.

In the event that the CIWQS SSO On-line Database is not available to submit required reports or certify reports, City staff must fax all required information to the San Diego Regional Water Quality Control Board office at 858.571.6972 in accordance with the time schedules identified in Table 4-1. The City is also obligated to enter all required information into the On-line SSO Database as soon as practicable.

4.4 Recordkeeping and Document Retention

The City must retain individual SSO records for a minimum of five (5) years from the date of the SSO occurrence. This period may be extended when requested by a San Diego Regional Water Quality Control Board Executive Officer. All records shall be made available for review upon State or Regional Board staff’s request. Specific records that must be retained include, but are not limited to:

• Certified reports as submitted on-line;

• Original recordings of continuous monitoring efforts;

• SSO call logs;

• Action(s) or planned action(s) to prevent future SSOs from recurring;

SSO Reporting Requirements

4-6

• Work orders, work completed, and maintenance records associated with responses and investigations of SSO related problems;

• A list and description of complaints from customers or others; and

• Documentation of performance and implementation measures.

To facilitate the City’s ability to report regularly on SSOs, the Public Services Supervisor maintains an Excel™ spreadsheet that contains information about each SSO. Attachment I shows the data and attributes collected about each SSO. The Public Services Supervisor should input data as soon a practicable after an SSO event. This database can be queried for trends and used as a cross reference for the on-line SSO reporting requirements.

Chapter 5 Training and Safety Appropriate staff, including Wastewater, Storm Water, and Solid Waste staff as well as the Sweeper Operator and Weekend Maintenance Worker III will participate in regularly scheduled training sessions to assist response crews in awareness of their responsibilities while executing their duties. These training sessions will be organized based on the latest SSORP, as well as other reference materials. Training sessions shall also incorporate hands-on field demonstrations to insure the preparedness of all response personnel to all anticipated situations. An overview of the Sewer System Management Plan (SSMP) and the SSORP should be provided to City staff. This will serve as a mode of instructing staff on the SSMP, SSOs, and required documentation. Field demonstrations will be performed to test equipment, response time, training effectiveness, resources, and manpower capabilities. Additionally, City staff will make the SSORP available to any contractor who may provide service to the City to ensure that the contractors are properly informed of the response procedures. Training and event participation will continue to be documented and maintained. Currently, Wastewater Maintenance staff is encouraged to receive training through various vendors. Additionally, the City requires specific staff levels to receive training and certification through the California Water Environment Association (CWEA). All Wastewater Maintenance staff is required to have a Class B license and air and tank endorsements. Additional certification requirements may be imposed if deemed necessary by the SDRWQCB.

Chapter 6 Updating this SSORP This SSORP reflects the City’s established procedures for responding to reports of possible and confirmed SSOs originating from its wastewater collection system. As policies change and response procedures are refined, the SSORP will be reviewed and modified to reflect all necessary changes.

6.1 Review and Update of the SSORP

City staff shall maintain this SSORP, and amend or update it as necessitated by the addition of new facilities, or changes in the operation or maintenance of the wastewater collection system that may materially affect the potential for SSOs. At a minimum, the plan will be reviewed annually and will include updating telephone numbers and forms in the attachments as well as a review of procedures. The annual review of the plan will also ensure all provisions of the plan are being met and implemented. City staff shall also review and amend this SSORP as appropriate after any SSO occurrence. SSORP deficiencies and updates will be addressed and modified accordingly. The plan performance will be routinely evaluated, reviewed and updated.

6.2 SSORP Availability

The SSORP should be distributed to the appropriate staff, City Departments, RWQCB, and be made available to the public for review. Staff shall ensure that this SSORP is readily available to sewer system maintenance personnel, and that said personnel are familiar with the plan and comply with it at all times.

Attachment G Possible Methods for Estimating Spill Volume

City of Coronado SSORP Page 1 of 3 Revised 06/2009 Attachment G

Possible Methods for Estimating Spill Volume

A variety of approaches exist for the estimation of the volume of a sanitary sewer overflow. This attachment documents three methods that are most often employed. Other methods are also possible. The person preparing the estimate shall use the method most appropriate to the SSO in question using his/her judgment. Every effort shall be made to make the best possible estimate of the volume. Method 1 Eyeball Estimate The volume of very small SSOs can be estimated using an “eyeball estimate.” To use this method, imagine the amount of water that would spill from a bucket or a barrel. A bucket contains 5 gallons and a barrel contains 50 gallons. If the SSO is larger than 50 gallons, try to break the standing water into barrels and then multiply by 50 gallons. This method is useful for contained spills up to 100 gallons. Method 2 Measured Volume The volume of some small SSOs can be estimated using this method if it is not raining. In addition, the shape, dimensions, and depth of the spilled sewage are needed. The shape and dimensions are used to calculate the area of the spill and the depth is used to calculate the volume.

Step 1 Sketch the shape of the contained sewage

Step 2 Measure or pace off the dimensions

Step 3 Measure the depth in several locations

Step 4 Convert the dimensions, including depth to feet.

Step 5 Calculate the area using the following formulas:

Rectangle Area = length x width

Circle Area = diameter x diameter x 0.785

Triangle Area = base x height x 0.5

Step 6 Multiply the area times the depth

Step 7 Multiply the volume by 7.5 to convert it to gallons Method 3 Duration and Flow Rate Calculating the volume of SSOs where it is difficult or impossible to measure the area and depth requires a different approach. In this method, separate estimates are made of the duration of the SSO and the flow rate. The methods of estimating duration and flow rate are: Duration: The duration is the elapsed time from the start time to the end time, when the SSO stopped.

Start time is sometimes difficult to establish. Here are two approaches:

• For very large overflows, changes in flow on a downstream flow meter can be used to establish the start time. Typically the daily flow peaks are “cut off” or flattened by the loss of flow. This can be identified by comparing hourly flow data.


• Conditions at the SSO site change with time. Initially, there will be limited deposits of grease and toilet paper. After a few days to a week, the grease forms a light colored residue. After a few weeks to a month the grease turns dark. In both cases the quantity of toilet paper and other materials of sewage origin increase in amount. These changes with time can be used to estimate the start time in the absence of other information.

• Sometimes it is simply not possible to estimate the start time. End time is usually much easier to establish. Field crews on-site observe the “blow down” that occurs when the blockage has been removed. The “blow down” can also be observed in downstream flow meters.

Flow Rate: The flow rate is the average flow left in the sewer system during the time the SSO stopped. There are three ways to estimate the flow rate:

• San Diego Manhole Flow Rate Reference Sheet: This sheet, presented in Figure G-1, shows the sewage flowing from a manhole cover for a variety of flow rates. The observations of the field crew are used to select the approximate flow rate from the chart.

• Flow meter: Changes in flows in the downstream flow meters can be used to estimate the flow rate during the spill (better for large SSOs).

• Estimate based on up-stream connections: Once the location of the SSO is known, the number of upstream connections can be determined from system maps. Multiply the number of connections by 200 to 250 gallons per day per connection, 8 to 10 gallons per hour per connection, or other flow rates that are consistent with the City’s data for its connections.

Once duration and flow rate have been estimated, the volume of the SSO is the product of the duration in hours or days times the flow rate in gallons per hour or gallons per day.

Chapter 1 Introduction Sanitary Sewer Overflows (SSOs) are a major concern to wastewater agencies across the State of California. There are several factors that contribute to the periodic failures of wastewater collection systems that may potentially result in the occurrence of an SSO. SSOs can be attributed to many causes, including high concentrations of fats, oils, and grease (FOG), roots, the poor condition of the wastewater collection system lines, wet weather flows, or a combination of the causes. It has been estimated that more preventable SSOs are caused by FOG than by any other factor, prompting state and local regulating agencies to focus on FOG Control Program development as a key element in complying with the mandates set forth under the General Waste Discharge Requirements for Sanitary Sewer Systems Order No. 2006-0003 (WDRs), and supplemented in the San Diego Region Order R9-2007-0005 adopted on February 14, 2007. To comply with one of the eleven (11) mandatory elements of the WDRs, the City of Coronado (City) has prepared a FOG Control Program to effectively reduce the quantity of FOG and other debris discharged to the wastewater collection system that may cause sewage collection system blockages or SSOs. This FOG Control Program establishes the formal procedures that City staff implements to effectively reduce the potential for SSOs and the direct or indirect discharge of wastewater, or other waste, containing FOG into the City’s wastewater collection system. Chapter 1 provides an overview of the FOG Control Program, the purpose and goals of the program, the regulatory authority requiring this program, an overview of this document’s organization, and definitions of terms contained in this document.

1.1 FOG Control Program Overview

A FOG Control Program documents the processes and procedures an agency implements to ensure that SSOs caused by the discharge of FOG are minimized and potentially eliminated. The FOG Control Program also includes informing residents and business owners of the proper methods to dispose of FOG. Proper disposal of FOG is important since it can accumulate in the sewer system and eventually block collection pipes and sewer lines, resulting in backups and overflows on streets, properties and even in private residences. Sewer overflows are unsanitary and negatively impact the environment. They are costly to agencies and the rate payers since the expense of cleaning up overflows and any repairs associated with improper disposal of FOG can lead to increased sewer rates. To manage and control, in a cost effective manner, the discharge of FOG into the City’s wastewater collection system to the maximum extent practicable, this FOG Control Program includes policies and procedures to address potential FOG contribution to the wastewater collection system by Food Service Establishments (FSEs).

Introduction

1-2

1.2 Purpose and Goals

The primary goal of a FOG Control Program is to reduce SSOs and blockages to protect public health and the environment by minimizing public exposure to unsanitary conditions. A FOG Control Program includes control mechanisms that will establish regulations and policies for the disposal of FOG from FSEs. By controlling the FOG discharge into the wastewater collection system, FOG buildup in the system can be lessened, thereby increasing the operating efficiency of the system and reducing the number of sewer line blockages and overflows. In addition, an effective FOG Control Program can minimize revenue losses associated with maintenance activities necessary to remove FOG from the collection system and reactionary enforcement actions required to restrict public activities and access to public facilities due to an SSO occurrence. The purpose of this FOG Control Program is to facilitate the maximum beneficial public use of the City’s wastewater collection system while preventing blockages of sewer lines and pump stations, and reducing the adverse effects on sewage treatment operations resulting from discharges of FOG into the system. This program provides the City with a comprehensive document that includes components necessary to reduce the quantity of FOG discharged into the City’s wastewater collection system to achieve the goal of minimizing SSOs caused by excessive FOG.

1.3 Elements of the FOG Control Program

Implementation of a long-term FOG Control Program includes various elements of controls for all new and existing FSEs. Elements of the FOG Control Program include the following:





• Recordkeeping and Reporting Requirements

• Permits, Inspections, and Enforcement

• Drawing Submittals


Implementation of control mechanisms may require preparation of and/or revisions to FOG-related Municipal Codes and FOG related permit(s), which serve to define general prohibitions and restrictions on discharges, facility requirements, administrative requirements, procedures for recovering costs associated with FOG discharges and blockages, and enforcement tools for implementing the program.

1.4 Organization of this Document

This document provides the guidelines necessary for the City to implement a comprehensive FOG Control Program. It illustrates the participation required on behalf of City staff and the FSEs to allow for effectively managing and controlling the discharge of FOG into the City’s wastewater collection system. In addition to providing a summary of the elements of a FOG Control Program, Chapter 1 also contains information regarding the regulatory requirements and common acronyms and definitions used within the document. Chapter 2 contains information on several basic elements of a FOG Control Program which FSEs are required and responsible for establishing, implementing and maintaining. Chapter 3 includes various recommended Best Management Practices (BMPs) designed to effectively reduce the quantity of FOG discharged from FSEs into the City’s wastewater collection system. Also included is information to effectively implement the recommended BMPs. Chapter 4 includes information regarding the requirement for pretreatment of wastewater flows generated at FSEs prior to discharging into the City’s wastewater collection system. Pretreatment includes installation of grease removal devices or a City-approved site specific pretreatment program in existing and new FSEs. It also includes maintenance and inspection requirements. Chapter 5 addresses Food Establishment Waste Discharge (FEWD) Permit requirements for new and existing FSEs. Chapter 6 includes information regarding the inspection and various enforcement procedures that may be applied for compliance with the FOG Control Program. Chapter 7 addresses the requirements for the submittal of development plans for new and remodeled facilities. Chapter 8 describes current public outreach efforts to educate the public about the program and how to reduce FOG.

1.5 Regulatory Requirements

The EPA, in its general pretreatment regulations (40 CFR Part 403) and the City, in its Municipal Code, Section 60.04.900, Prohibitions, prohibits any user, including FSEs, from discharging solid or viscous substances, such as FOG wastes, in such quality, size, or quantity that may cause obstructions (blockages) to the flow in the wastewater system and interfere with the operation of the wastewater system or the Public Owned Treatment Works (POTW).

Introduction

1-4

The following regulatory requirements establish the impetus for the City to develop a FOG Control Program, implement the elements, and thoroughly follow procedures to ultimately minimize the potential of SSOs due to the discharge of excessive FOG into the City’s wastewater collection system. California Water Code Section 13271, California Code of Regulations: Section 13271 of the California Water Code, Title 23 of the California Code of Regulations, prohibits the discharge of sewage and hazardous material into the waters of the State and requires the proper notification of authorized agencies in the event of an SSO. Entities which do not properly follow the requirements of this section may be found guilty of a misdemeanor and punished by fine, imprisonment, or both. California Waste Discharge Requirements: On May 2, 2006, the State Water Resources Control Board adopted the Statewide General Waste Discharge Requirements for Sanitary Sewer Systems, Order No. 2006-0003. The WDRs are applicable to all federal and state agencies, municipalities, counties, cities, and other public entities that own or operate wastewater collection systems greater than one mile in length that collect and/or convey untreated or partially treated wastewater to publicly owned treatment facilities in the State of California. Specifically, the WDRs require compliance with the provisions contained in Division 7 of the California Water Code as well as the additional provisions included with the WDRs, which require the City to evaluate its service area to identify and assess FOG related problems. If it is determined that a FOG source control program is necessary, the City must prepare and implement a FOG Control Program. This FOG Control Program fulfills the requirement and documents the City’s efforts to comply with the WDRs. Clean Water Act, Section 1251 of Chapter 33 of the United States Code: In 1972, the federal Congress enacted the Federal Water Pollution Control Act, commonly known as the Clean Water Act (CWA). The CWA prohibits the discharge of pollutants, including sewage, into public waters of the United States. The federal government has the authority to enforce compliance with the CWA via specific permits, such as National Pollutant Discharge Elimination System permits, as well as court actions such as administrative orders and consent decrees.

1.6 Definitions

The following is a summary of acronyms and definitions typically used in a FOG Control Program. Also included are acronyms specific to the City of Coronado and its wastewater collection system. BMP This is the acronym for Best Management Practices. BMPs include schedules of activities, prohibitions of practices, maintenance procedures, and other management practices to prevent or reduce the introduction of FOG into wastewater collection facilities. Domestic Wastewater Liquid and waterborne wastes derived from the ordinary living processes in a dwelling unit, said wastes being of such character as to permit satisfactory disposal, without special treatment, into a public sewer.

FOG This is the acronym for Fats, Oils, and Grease. FOG includes any substance such as a vegetable or animal product that is used in or is a by-product of the cooking or food preparation process, and that turns or may turn viscous or solidify with a change in temperature or other conditions. FSE This is the acronym for Food Service Establishment. An FSE is a place where food is prepared and served for consumption by the public. This includes, but is not limited to, retail establishments selling prepared foods and drinks for consumption on the premises, and also cafeterias, lunch counters and refreshment stands selling prepared foods for immediate consumption. Restaurants, lunch counters, and drinking places operated as a subordinate service facility by other establishments shall also be included. Bars that do not serve food and markets that sell exclusively pre-packaged food and/or unprocessed fruit or vegetables are typically not included. Grease A liquid or solid material composed primarily of fats and oils from animal or vegetable sources. Grease Trap This is a device, typically located under sinks inside FSEs, designed to collect and contain food wastes and grease from the waste stream while allowing the remaining wastewater to be discharged to the wastewater collection system. Grease Interceptor This is a device, typically located underground and outside of an FSE, designed to collect and contain food wastes and FOG material from the waste stream while allowing the remaining wastewater to be discharged to the wastewater collection system. Grease Hauler A person who collects the contents of a grease interceptor or trap and transports it to an approved recycling or disposal facility. Non-Domestic Wastewater Wastewater that is not Domestic Wastewater. Non-Domestic Wastewater shall not include wastewater that arises from strictly residential activities and places engaged exclusively in retail business. Pretreatment or Treatment The reduction of the amount of pollutants, the elimination of pollutants, or the alteration of the nature of pollutant properties in wastewater to a less harmful state prior to or in lieu of discharging or otherwise introducing such pollutants into the City’s Sewer System or POTW. The reduction or alteration can be obtained by physical, chemical or biological processes or process changes by other means. Sewage Any liquid waste and waterborne solid waste resulting from residential, commercial, industrial, or institutional activities or uses.

Introduction

Chapter 2 Food Service Establishment Responsibilities According to the California Fats, Oils, and Grease Work Group, which is affiliated with Tri-TAC, it has been estimated that more SSOs are caused by excessive FOG than by any other factor. Therefore, active participation by the FSEs is imperative for the success of a FOG Control Program. This chapter includes a description of several basic elements that are part of a FOG Control Program for which each FSE is responsible. FSEs shall be responsible for ensuring that, at a minimum, the following basic elements of a FOG Control Program are established and maintained:

• Kitchen BMPs and Employee Training

• Spill Response Kits

• Grease Traps

• Grease Interceptors

• Notification

• Record Keeping and Reporting

• Compliance Agreement

• FEWD Permit

The following sections describe these basic FSE responsibilities in more detail.

2.1 Kitchen Best Management Practices (BMPs)

BMPs are practices, procedures, and maintenance activities performed by FSE staff to reduce the FOG in the wastewater discharged to the City’s wastewater collection system. Reducing the quantity of FOG discharged to the wastewater collection system reduces the potential for SSOs due to excessive FOG. Each FSE shall implement the BMPs as they pertain to handling and disposing of wastes containing FOG. As well, training of new and existing employees to properly implement BMP activities adopted for the establishment will serve to ensure and reinforce proper handling and disposal of FOG. Kitchen BMPs are described in greater detail in Chapter 3.

2.2 Spill Response Kits

In accordance with the City’s FOG Control Program, all FSEs should be equipped with a spill response kit to handle all unintentional spills. Spill response kits should include instructions to follow in case of a spill, cloths, plugs, a container of sealant, one bag of absorbent material and a pair of rubber gloves.

Food Service Establishment Responsibilities

2.3 Grease Traps

Grease traps are small grease control devices with manual grease removal, typically installed inside and above ground, generally cleaned and maintained by the FSE staff. A grease trap operates by gravity separation and uses a flow control device and baffles to allow the separation of floating FOG and settled solids. For the grease trap to perform correctly, the floating FOG and settled solids must be removed regularly, requiring frequent cleaning. The criteria for requiring the installation of a grease interceptor at new and existing FSEs is included in Chapter 4.

2.4 Grease Interceptors

A grease interceptor is designed to use gravity to separate FOG from wastewater as the wastewater moves through the chamber. To perform according to design specifications, the chamber requires periodic cleaning and maintenance, including removal of accumulated FOG and solids, which must be disposed of in a proper manner at regular intervals. The City’s Municipal Code contains requirements for the installation and maintenance of a grease interceptor by FSEs that may be a source of food and/or FOG. The criteria for requiring the installation of a grease interceptor at new and existing FSEs is included in Chapter 4.

2.5 Notification

Occasionally, FOG-related SSOs occur or FSEs change ownership, expand, modify their fare, or close. These are key events that affect the City’s monitoring and enforcement procedures for controlling FOG. As a result, each FSE shall be responsible for the following notification procedures when necessary. 1) Notification of Discharge and/or SSO

a) In the event an FSE is unable to comply with the City Municipal Code and/or the FOG Control Program, due to a breakdown of equipment, accidents, or human error; or the FSE has reasonable belief that its discharge will violate the conditions of the FEWD Permit and/or the FOG Control Program, the FSE or its representative shall immediately notify:

Public Services (619)-522-7380

b) If the material discharged has the potential to cause or results in a sewer blockage or an SSO, the FSE shall immediately notify:

Public Service (619)-522-7380 or Coronado Police Dispatch Center (619)-522-7350


June 2009

c) Within five (5) days of an SSO occurrence, the FSE shall submit in writing a detailed report to the City’s Director of Public Services describing the cause of the discharge and the measures to be taken by the FSE to prevent similar occurrences in the future.

d) Such notification shall not relieve the FSE of any expense, loss, damages or other

liability that may be incurred as a result of damage to any wastewater systems, fish kills or any other damage or otherwise arising out of a violation of the City’s Municipal Codes or other applicable law.

2) Notification Regarding Change in Operations (60.04.150)

In accordance with City Municipal Code section 60.04.150, an FSE shall notify the Director of Public Services or the Director’s designee in writing prior to any facility expansion and/or remodeling or process modifications that may result in new or substantially increased FOG discharges or a change in the nature of the discharge. The FSE shall submit an amended discharge permit application including any information requested by the Director of Public Services or the Director’s designee for evaluation of the effect of such expansion and/or remodeling or process modifications on the FSE’s FOG discharge to the wastewater collection system. Additionally, the FSE shall notify the Director of Public Services or the Director’s designee as soon as practicable, in the event of a change in ownership, sale, or cessation of operation. All notifications shall be sent to:

City of Coronado Director of Public Services Wastewater Operations 101 B Avenue Coronado, CA 92118

The written notification shall state:

• FSE name;

• Name and title of the FSE’s contact person or person most knowledgeable concerning the facility expansion and/or remodeling or process modifications;

• Address and telephone number of the FSE;

• Date of the proposed facility expansion and/or remodeling or process modifications; and

• Reasons for the proposed facility expansion and/or remodeling or process modifications.

2.6 Recordkeeping and Reporting Requirements

Each FSE shall be responsible for maintaining accurate and up-to-date records documenting the cleaning and inspection of grease pretreatment devices. Inspection and cleaning records are required to be maintained on the premises for a minimum of three (3) years and made

Food Service Establishment Responsibilities

2-4

available to the Director of Public Services or the Director’s designee for review upon inspection of the facility. It is considered a violation of the City’s Municipal Code if the FSE fails to maintain and keep accurate and up-to-date records of all cleaning and maintenance of grease removal devices, removal of FOG wastes, and inspections performed by the Director of Public Services or the Director’s designee. Inspection records should, at a minimum, document the:

• Date of inspection;

• Name of person who performed the inspection;

• Estimated volume of FOG present at the time of inspection; and

• Signature of the manager or designee of the FSE.

Cleaning records should, at a minimum, document the:

• Date of maintenance;

• Name of company and person who performed maintenance;

• Estimated volume of FOG removed; and

• FOG disposal location.

A manifest from the permitted waste hauler is an acceptable record if it contains all of the above information.

2.7 Food Establishment Waste Discharge Permit

All FSEs requiring wastewater collection service are required to obtain a FEWD Permit from the City. The permit is legally binding and sets forth the terms, conditions, and criteria of the FOG Control Program. It is prepared and maintained under the authority of the City, and its provisions may be periodically modified. The City of Coronado’s Municipal Code contains requirements for a FEWD Permit for FSEs requiring connection to the City’s wastewater collection system. Compliance with the permit conditions is required before issuing or renewing the permit. Additional information regarding permitting is included in Chapter 5.

Chapter 3 Best Management Practices A fundamental component of the FOG Control Program is implementation of BMPs. The City is working with the food service industry to implement BMPs at all FSEs. This chapter contains several recommended operating procedures and guidelines designed to effectively reduce the amount of FOG discharged to the City’s wastewater collection system and to protect public health and the environment from the hazards presented by FOG-related SSOs.

3.1 Purpose of BMPs

BMPs are designed to assist facilities to comply with environmental regulations, prevent pollution, and serve to assist an FSE with the development of procedures and/or practices specific to the facility that reduce the amount of FOG in their wastewater discharge.

3.1.1 Description and Applicability

BMPs are practices that focus on good housekeeping measures and operations management techniques and include a series of activities that effectively manage and control disposal of waste FOG generated from the operation of an FSE. FSEs shall use BMPs to control FOG in the wastewater discharge and to prevent obstructions from entering the sewer mains.

3.1.2 Food Service Establishments

Benefits to FSEs include the reduction of FOG and solids accumulation in grease removal equipment, thereby reducing the maintenance needs and costs of the device, and thus reducing the potential for the FSE to cause a blockage resulting in an SSO. BMPs assist the FSEs to reduce costs associated with pumping frequencies, plumbing maintenance costs and compliance with environmental and regulatory standards. Due to the variety of FSEs that generate FOG, the BMPs implemented at each site are tailored to best accommodate the requirements of each FSE.

3.2 Best Management Practices

There are various simple and effective practices that all FSEs can implement to prevent and reduce the quantity of FOG discharged into the wastewater collection system. At a minimum, all FSEs are required to implement enforceable BMPs. A copy of the City’s recommended BMPs is included in Attachment A. The following BMPs are provided to assist FSEs with development of site specific procedures and/or practices to reduce the amount of FOG in their wastewater discharge.

Best Management Practices

3-2

• Trash Disposal: Dispose of food waste and fatty scraps into the trash or garbage bin. Do not discard into sink. Use plastic trash bags to prevent leaks and odors. Double-bag waste that has the potential to leak in trash bins. Ensure trash bins are covered when not in use and notify trash hauler if the bin leaks.

• Pre-Wash: Before washing pots, pans, dishware, floor mats, and work areas, dry wipe

or scrape food scraps, and dispose of them in trash.

• Use of Drain Screens: Install removable screens on all drainage pipes in food preparation areas. Keep screens in sink and floor drains clean and in good repair. Dispose of collected solids in trash, not down the drain.

• Yellow Grease Disposal: Dispose of grease and oil from cooking equipment (pots,

pans, and fryers) by pouring waste oil and yellow grease into covered containers (drums, barrels) for storage and recycling. Provide secondary containment to capture any liquid grease or oil that may spill from the primary container. Use a licensed waste hauler or recycling facility to dispose of liquid grease and oil before the container is full. Keep a written log with manifests and invoices of waste oil pick ups to show the City’s authorized inspector during the site inspection.

• Mat Cleaning: Clean and wash floor mats in a utility mop sink connected to grease

removal equipment. DO NOT empty mop or wash water into storm drains.

• Hood Cleaning: Clean hoods and filters in sinks that flow to grease removal equipment and clean as frequently as necessary to maintain good operating condition. Use a licensed waste hauler to dispose of wastewater collected from cleaning hoods and filters.

• Spill Prevention: Place absorbent materials, such as paper towels or pads, under fryer

baskets and other areas where grease may drip or spill during cooking, frying or during the transfer of grease to storage or disposal containers.

• Spill Kits: Maintain a spill kit accessible for use by employees that includes absorbent

pads, kitty litter or equivalent absorbing material, and paper towels. Require the use of the spill kit to clean up spilled FOG.

• Super Hot Water: DO NOT pump water hotter than 140oF through grease removal

equipment.

• Employee Training: Post signs to show kitchen best management practices in food preparation, dishwashing, and maintenance areas. Employees will be trained regularly and records of staff training retained.

Additionally, to ensure that the building drains and sanitary service lines are properly maintained to avoid FOG and debris accumulation that may result in or contribute to SSOs, it is recommended that FSEs have their building drains and service lines professionally cleaned on a regular basis.

3.3 Implementation of BMPs

The success of a BMP program requires proper implementation and continual re-enforcement of the adopted BMPs.

3.3.1 Employee Training and Awareness

The effectiveness of BMPs is largely dependent upon the training of employees on the proper BMP implementation methods of BMPs for FOG waste handling and disposal. To promote effective and proper employee implementation, each FSE should at a minimum:

• Train employees on the BMPs adopted for their establishment;

• Maintain records of employee training;

• Provide constant reinforcement on proper disposal of FOG with employees; and

• Post “No Grease” and BMP signs near sinks and dishwashers. Signs should be written in the language(s) that is commonly spoken by employees.

Posting signs at key locations serves to remind employees of the adopted BMPs and reinforce the importance of proper and continual implementation. Routine training ensures that all new employees are properly trained and that existing employees receive updated information. Training of employees should include information on the potential environmental and facility impacts of grease in the wastewater collection system.

3.3.2 Inspections

Routinely scheduled inspections by the Director of Public Services or the Director’s designee to inspect FSEs for proper implementation of BMPs serve to reinforce the importance of limiting FOG discharge into the City’s wastewater collection system and reduce the potential of SSOs due to excessive FOG. Training of the FSE staff ensures that employees are trained on the proper FOG handling and disposing methods and that BMPs are being implemented.

Chapter 4 FOG Removal Equipment Pretreatment of wastewater flows generated at FSEs removes excessive amounts of FOG in the wastewater prior to its being discharged into the City’s wastewater collection system. A pretreatment program requires FOG producing FSEs to install the appropriate type and size of grease removal equipment. Alternative oil and grease removal technologies shall be subject to written approval by the Director of Public Services or the Director’s designee. The equipment approved for the collection, filtration, and storage of FOG must be regularly and appropriately maintained. This chapter describes acceptable grease removal equipment, including grease interceptors. Grease interceptors, or other approved grease control devices deemed necessary by the Director of Public Services or the Director’s designee, shall be installed solely at the FSE’s expense. Proper operation, maintenance, and repair of grease traps or interceptors or other approved pretreatment devices shall be performed solely at the FSE’s expense.

4.1 Grease Traps

Grease traps are small devices installed inside a facility and connected directly to the outgoing drains of sinks. Grease traps are designed to separate and retain grease from the wastewater generated by the FSE. Figure 4-1 illustrates the common components of a grease trap.

Figure 4-1 Typical Grease Trap

FOG Removal Equipment

4-2

Typically, grease traps are installed in kitchens under the floor or near the sink, and are much smaller than grease interceptors. Since grease traps hold small quantities of captured FOG, such traps must be cleaned frequently. For grease traps to be effective, the units must be properly sized, constructed, and installed in a location to provide easy access for cleaning and an adequate retention time for settling and accumulation of the FOG. Installation Requirements An FSE may use or may be required to install grease traps, in lieu of installation of a grease interceptor when:

• Installation of an interceptor cannot physically be accomplished; • There is not adequate slope for gravity flow between a proposed grease interceptor and

the private collection lines or the public sewer; and/or • No alternative pretreatment device can be installed.

Sizing and installation of grease traps shall be per the manufacturer’s recommendations and conform to the latest edition of the California Plumbing Code. Maintenance Requirements Businesses shall be responsible for performing adequate testing and monitoring to ensure that the grease traps are functioning properly. Minimum grease trap operation and maintenance requirements include the following:

• Grease traps shall generally be operated and maintained in accordance with the manufacturer’s specifications.

• Grease traps shall be maintained in efficient operation condition by removing accumulated grease on an as needed basis, or at the frequency specified by the manufacturer, but not less than on a weekly basis.

• Grease traps shall be inspected periodically, but in no event less than once a month, to check for leaking seams and pipes, and for effective operation of the baffles and flow-regulating device. Grease traps and their baffles shall be maintained free of all caked-on FOG and waste. Removable baffles shall be removed and cleaned during the maintenance process.

• Dishwashers and food waste disposal units shall not be connected to or discharged into any grease trap.

• All FSEs required to install and maintain a grease trap shall maintain a maintenance record that documents the cleaning activities for the grease traps. Records should include the name of employee who performed the cleaning, date/time of cleaning,


June 2009

4-3

amount of grease removed, and the disposal location for the grease. Records shall be kept on site for a minimum of three (3) years.

All maintenance records shall be made available to the City’s Director of Public Services or the Director’s designee at the time of inspection and/or at the Director of Public Services’ or the Director’s designee’s request.

4.2 Grease Interceptors

The installation and maintenance of a grease interceptor is an important measure for ensuring that the FSE does not contribute to potential problems in the wastewater collection system. Grease interceptors are located outside, underground and include a multi-compartment tank that serves to reduce the quantity of FOG in the wastewater before discharging the wastewater into the wastewater collection system. Grease interceptors typically include two compartments that function to physically separate, remove, and retain FOG and solids from wastewater discharged from the FSE. Due to the differences in specific gravity, the FOG rises to the top and is retained by a baffle installed in the effluent chamber. The separated FOG and solids are retained while the liquid flows to the wastewater collection system. The hydraulic detention capacity of the unit decreases as grease and solids accumulate; therefore, regular pumping, cleaning, and maintenance of grease interceptors are essential to ensure proper operation. Figure 4-2 illustrates the common components of a grease interceptor. For the units to be effective, they must be properly sized, constructed, and installed in a location that provides easy access for inspection and cleaning. Grease interceptors are pretreatment facilities that are subject to plan submission and operations requirements according to the provisions included in the City’s Municipal Code section 60.04.140.

Figure 4-2 Typical Grease Interceptor


4-4

4.3 Installation Requirements

Individual grease interceptors may be required for FSEs whether or not such facilities are located in a separate building or structure or occupy space in a building or structure that is occupied by other businesses. If the volume or nature of food service provided by the establishment involves significant food preparation, a discharge of FOG waste is highly likely and a grease interceptor may be required. Exceptions to the requirement for a grease interceptor are pursuant to the permit conditions set forth in Chapter 5. Each new grease interceptor that is installed to replace or upgrade an existing grease interceptor will be required to meet all criteria in accordance with City requirements. For properties with multiple FSEs on a single parcel, each FSE is required to install and maintain a separate grease interceptor.

4.4 Maintenance Requirements

Each FSE shall be responsible for adequate maintenance, testing, and monitoring of the grease interceptors to ensure that the grease interceptors are functioning properly and to the City’s standards. At a minimum, maintenance procedures for grease interceptors should include:

• Observe proper grease interceptor cleaning and maintenance procedures to ensure that the device is operating properly. Regular and proper service maximizes interceptor efficiency, prevents spills and minimizes odor.

• Train all employees to regularly check the depth of solids and thickness of retained FOG. Generally, an interceptor loses its effectiveness and does not separate FOG properly when excessive amounts of FOG and/or solids accumulate. The interceptor requires servicing when the combined thickness of solids at the bottom and FOG material on the surface is at 25% of total liquid depth in the interceptor. The frequency of servicing is determined by the accumulation rate of FOG and solids.

• Inspect grease interceptor after cleaning to ensure that service was performed correctly, that entire contents were pumped out, and to verify that all pipes and baffles are intact.

• Maintain a maintenance record that documents the cleaning activities for the grease interceptor. Records should include the name of the company who performed the cleaning, date/time of cleaning, amount of grease removed, and the disposal location for the grease. Records shall be kept for a minimum of three (3) years.

4.5 Cleaning

Cleaning must be performed by a licensed waste hauler with an approved license from an authorized agency. All chambers of a grease interceptor shall be left completely empty upon completion of the pumping operation. The grease mat, liquids, sludge, and scrapings from the interior walls must be completely removed. Under no circumstances will the waste hauler reintroduce the removed water or materials into the City’s wastewater collection system. All

water and materials removed from the grease interceptor must be disposed of at qualified disposal stations. Since the FSE is the generator of the grease waste, it is liable for the condition of its pretreatment devices, and shall be responsible for payment of all cleaning service fees. It is recommended that the FSE owner or designee be present during the cleaning and maintenance activities to ensure that the grease interceptor is being completely and properly cleaned and maintained. A maintenance log serves as a record of the cleaning frequency and can assist the FSE manager in reducing costs by efficiently scheduling service. A grease interceptor shall be considered out of compliance if the Director of Public Services or the Director’s designee determines any of the following conditions exist:

• The interceptor is incapable of retaining adequately the floatable and settleable material in the wastewater flow;

• The interceptor is structurally incomplete;

• Any part of the grease interceptor is broken, missing, or in need of total replacement;

• The interceptor directly or indirectly causes damage to the City’s sewer system;

• The interceptor is incorrectly sized for the facility; or

• The total volume of captured grease and solid material displaces more than 25% of the capacity of the interceptor as calculated using an approved dipping method.

When the Director of Public Services or the Director’s designee finds a grease interceptor out of compliance, the FSE owner/operator will be properly notified of the violation and be required to properly install, at the FSE owner’s/operator’s expense, an interceptor in compliance with the City’s requirements or increase cleaning frequency to ensure that the combined thickness of solids at the bottom and FOG material on the surface does not exceed 25% of total liquid depth in the interceptor.

4.6 Inspections

The City’s Director of Public Services or the Director’s designee may inspect and sample any FSE’s wastewater discharges to determine whether conditions of the FEWD Permit are being met. Reasonable access to the FSE shall be made available when inspection and/or sampling of the wastewater are required. The FSE shall make the following available for the purpose of inspections:

• Access to grease pretreatment devices;

• Manifests, receipts, and invoices of grease pretreatment device maintenance;

• Documents identifying the waste hauler; and

• Documents identifying the disposal site locations.

4.7 Monitoring Facilities

Monitoring facilities serve to permit sampling and flow measurement of the wastewater steam and may be utilized to ensure that the FSE does not contribute excessive FOG quantities that may result in potential problems of the wastewater collection system. The Director of Public Services or the Director’s designee may require the installation and maintenance of sewage monitoring devices and controls to facilitate implementation of the provisions contained in the Municipal Code. The type of monitoring and/or control facilities to be implemented must be approved by the Director of Public Services or the Director’s designee, and shall be in accordance with the City’s requirements.

4.7.1 Other Monitoring Equipment and Controls

The Director of Public Services or the Director’s designee may require other or additional devices for monitoring, treatment, and control of wastewater volume and quality. The Director of Public Services or the Director’s designee shall approve such devices on a case by case basis for each specific application and purpose.

4.7.2 Monitoring Facility Locations

Typically, monitoring facilities are located on the FSE premises. However, with the approval of the Director of Public Services or the Director’s designee, the monitoring facility may be located in the public right-of-way and located such that it will not be obstructed by landscaping or parked vehicles. Whether constructed on the premises or within the public right-of-way, the location of approved monitoring facilities shall be provided in accordance with the City’s requirements and all applicable local construction standards and specifications. The approved devices shall be tamper-proof or tamper-resistant and where appropriate, be integrated such that monitoring or treatment devices cannot be bypassed or defeated. As well, they shall be installed in a manner that can be inspected and verified by City staff at all reasonable hours.

4.7.3 Maintenance Requirements

Each FSE shall be responsible for adequate maintenance, calibration and standardization of wastewater monitoring, treatment, and control devices and systems. The FSE is responsible for ensuring that each facility is functioning according to the manufacturer’s specifications or as required by the City’s Municipal Code. Maintenance, calibration, and standardization records shall be maintained for a minimum of three (3) years.

Chapter 5 Food Establishment Waste Discharge Permit Requirements The permit application process allows the City to commence the tracking and monitoring of FSEs to control the discharge of FOG into the wastewater collection system. This section describes the general criteria of a FEWD Permit.

5.1 Permit Requirements

All FSEs are required to obtain and renew a FEWD Permit to discharge wastewater into the City’s wastewater collection system. Requirements of the permit will vary among FSEs, but, in general, each permit will require the FSE to meet the requirements for installation of FOG removal and monitoring equipment, comply with applicable City policies, and pay all required fees. Fees for obtaining the required permit(s) will be assessed and reflect the specific permit requirements. As well, the permit will contain specific conditions applicable to the particular operation or location. A permit is issued for a specified time period, not to exceed five years and may be issued for a period of less than one (1) year. A copy of the City’s FEWD Permit is included in Attachment B.

5.2 New FSEs

Individual grease interceptors shall be required for all new FSEs on a case-by-case basis and per City policy. During the plan review/building permit process, there is a full opportunity to plan for the new installation with the cost component being part of the facility’s initial capital investment. Each new grease interceptor or trap that is installed to replace or upgrade existing grease interceptors or traps will be required to meet all criteria stated in the City’s Municipal Codes, the adopted Uniform Plumbing Code, and plan check requirements.

5.3 Existing FSEs

FSEs planning or undergoing substantial remodeling have opportunities similar to new FSEs to design and install grease interceptors, and therefore will be required to comply with the same conditions as new FSEs. Existing FSEs that discharge to sewer lines known to be a source of SSOs or sewer lines where frequent cleaning is required may be required to install a complete grease interceptor system. Site specific requirements vary according to the location of the sewer lines identified as “high frequency maintenance sites.” Since there is the potential for new high frequency maintenance sites to develop, a site-specific preventive approach in dealing with the FSE must be developed based on the quantity of FOG generated. This is indicated by the nature and magnitude of the operation and provides the apparent immediate benefit of preventing blockages and sewer spills.

Food Establishment Waste Discharge Permit Requirements

5-2

5.4 FSE Site Modifications

In addition to new construction and the remodel and/or expansion of an existing structure, changes in the operation of the FSE may also prompt the requirement for the installation of pretreatment devices. The following is a list of changes that could initiate an increase in FOG discharges and require owners of FSEs to install pretreatment devices:

• Menu changes;

• Menu expansion;

• Seating capacity, operations, equipment, or production expansion;

• Changes in facility management and the use of BMPs;

• Changes in discharge volume;

• Changes in nature of discharge; and/or

• Changes to the building plumbing/sewer system. The owner or operator of the FSE shall notify the Director of Public Services or the Director’s designee when any of these events are planned in order to determine the overall impacts which may trigger modifications to the existing permit and/or pretreatment devices. The Director of Public Services or the Director’s designee may require the FSE to submit an amended FEWD Permit application in accordance with the City Municipal Code for review and approval.

5.5 Exemption from Food Establishment Waste Discharge Permit

At the discretion of City staff, FSEs with limited food preparation capabilities may be exempt from obtaining a FEWD Permit. Exempted establishments shall be engaged only in reheating, hot holding or assembly of ready-to-eat food products and, as a result, there is no wastewater discharge containing significant amounts of FOG. An FSE with limited food preparation capabilities does not include any operation that changes the form, flavor or consistency of food.

Chapter 6 Inspection and Enforcement The City’s objective is to implement and enforce actions against users of the wastewater collection system who violate the prohibition of discharging FOG into the wastewater collection system. The City will initiate enforcement actions for noncompliance. It is also possible for other regulatory agencies, including the EPA or the State, to initiate their own enforcement actions. The City has a range of enforcement responses that can be applied to gain compliance with the FOG Control Program and respective City Municipal Code. Enforcement actions are implemented when an owner of an FSE has failed or refused or violated compliance requirements. They include an escalating response strategy to violations. Fines may be implemented in conjunction with the City’s established Municipal Code procedures or permitting processes and procedures.

6.1 Inspections

To determine whether an FSE is in compliance with the conditions of the FEWD Permit, FOG Control Program, and City Municipal Code, the Director of Public Services or the Director’s designee will inspect each FSE a minimum of once annually. A copy of the City’s FEWD Inspection Form, used during FSE inspections, is included in Attachment C to facilitate documenting potential violations of specific sections of the ordinances. Reasonable access to all parts of the FSE shall be made available when inspection and/or sampling of the wastewater are required. The FSE shall make available, for the purpose of inspection, the following:

• Access to grease pretreatment devices;

• Access to flow measuring and monitoring devices;

• Manifests, receipts, and invoices of grease device maintenance;

• Documents identifying the waste hauler carrier;

• Documents identifying the disposal site locations; and

• Records of employee training in best management practices. For FSEs noted to have FOG discharge and/or grease removal equipment, the following items will be inspected once every twelve (12) month period for permit, FOG Control Program, and code compliances:

• Permit Renewals

• BMP Inspections

• Grease Removal Equipment

• Cleaning Service Records

Inspection and Enforcement

6-2

Based on the results of the inspection, the status of the FSE’s existing FEWD Permit may be renewed, extended or revoked. If violations are encountered, the Director of Public Services or the Director’s designee shall note the violation(s) and include a description(s) of the violation(s) on the FEWD Inspection Form. The documentation of the violation(s) shall serve as the formal ‘Notice of Non-Compliance’ or ‘Notice of Violation.’ Additionally, the Director of Public Services or the Director’s designee shall schedule a follow-up inspection of the FSE to determine whether the required corrective actions have been implemented and if additional improvements are necessary.

6.2 Enforcement

All users of the City’s wastewater collection system and facilities are required to comply with the FOG Control Program and all applicable elements of the City’s Municipal Code.

• Issuing written notices of violation which may require a compliance plan for the satisfactory correction of the violation;

• Increasing the inspection schedule;

• Requiring a Show Cause Hearing;

• Terminating sewer service;

• Pursuing civil penalties and/or criminal penalties;

• Suspending or revoking of the FEWD Permit; and/or

• Assessing costs and charges to reimburse the City to clean and/or repair damages to the wastewater collection system or other affected sewer facilities.

6.2.1 A Compliance Order

The Director of Public Services or the Director’s designee can direct the user to achieve or restore compliance with the FEWD Permit or any other provisions of the City’s Municipal Code, by a specific date. The terms of the order need not be discussed with the user in advance.

6.2.2 A Show Cause Hearing

Upon determination by the Director of Public Services or the Director’s designee that an FSE or owner of the property is in noncompliance with its FEWD Permit or any other applicable provision of the Municipal Code, the Director of Public Services or the Director’s designee may require a Show Cause Hearing that requires the owner of the FSE or property to appear at the City office for a Show Cause Hearing on a specified date and time to show cause to the City as to why criminal and/or civil actions should not be taken against the user and/or why sewer service should not be discontinued to the user’s facility.

6.2.3 Suspension or Termination of Sewer Service

In the event that a violation of the City’s Municipal Code or FEWD Permit conditions causes or contributes to a sewer system overflow event or an overflow event emanating from a sewer lateral or private system and such event is creating or contributing to an immediate or impending threat to the public’s health or safety or to the environment, the Director of Public Services or the Director’s designee may discontinue the sewer and/or water service to the FSE or to the property, and such service discontinuation shall remain in effect until the private sewer lateral impairment is repaired or until the matter is heard and sewer and/or water service is ordered restored by the Director of Public Services or the Director’s designee.

Inspection and Enforcement

6-4

6.2.4 Administrative Enforcement of Civil and/or Criminal Penalties

The Director of Public Services or the Director’s designee may pursue Administrative Civil Penalties against any user who has violated or is violating any prohibition, limitation, or requirement contained in the City’s Municipal Code and/or the FEWD Permit. The enforcement response shall be dependent upon the magnitude and duration of the violation, its effect on the POTW and the environment and whether or not there is a danger to the health and safety of the general public due to a wastewater generation or discharge. Civil Penalties All users of the City’s wastewater collection system and facilities are subject to the Civil penalties assessed in accordance with the City’s Municipal Code as well as additional provisions to further enforcement actions of federal, state and local regulatory agencies. In the event the City is the subject of fines, penalties, or legal actions as a result of actions of the FSE or other parties in violation of the FOG Control Program, the FEWD Permit or the City’s Municipal Code, the City shall be entitled to recover from the responsible party(ies) all costs and expenses to which the City has been subjected. Civil penalties shall be assessed according to the City Municipal Code or as assessed by the City Manager or the City Council based on the extent of the violation(s). Criminal Penalties Except as otherwise provided by law or City Municipal Code, any person who violates any provision of the FOG Control Program, the FEWD Permit, or the City’s Municipal Code may be convicted of a misdemeanor, which upon conviction may be punishable by a fine of not more than $10,000 for each day in which such violation occurs, or punishment by imprisonment in the City or county jail for not more than one (1) year, or by both the fine and imprisonment. Suspension or Revocation of Permit A FEWD Permit may be suspended and/or revoked for the following reasons:

• Failure to comply with the conditions of the FEWD Permit or City Municipal Code;

• Failure to install required grease pretreatment or monitoring devices as required by the FEWD Permit;

• Failure to comply with the reporting and/or pretreatment requirements or pretreatment device maintenance as required by the FEWD Permit and the City Municipal Code;

• Failure to pay all applicable charges and fees;

• Failure to report significant changes in operations, wastewater volume, constituents, and/or characteristics prior to discharge;

• Tampering with monitoring equipment;

• Failure to meet effluent limitations;

• Failure to comply with a Compliance Order issued to require compliance with a FEWD Permit or other provision of the City’s Municipal Code;


June 2009

6-5

• Knowingly providing a false FEWD Permit application or making false representations, or submitting false documents, reports or logs to the City’s Director of Public Services or the Director’s designee;

• Failure to notify the City of modifications to the FSE facilities such that the conditions are not consistent with the information presented in the original FEWD Permit application;

• Refusal to allow inspections during normal business hours or after hours if emergency conditions exist (overflow or suspected overflow);

• Interference with the Director of Public Services or the Director’s designee during the FSE inspection or in sampling an FSE’s discharge or in inspecting and sampling an overflow event; and/or

• Causing or contributing to sewer blockages or sewer overflows within the public sewer, or failing to address the conditions leading to more than one (1) overflow event from a private system within a twelve (12) month period.

6.2.5 Cost Recovery (Clean Up Costs)

Enforcement activities often commence with investigations of blockages in and overflows from the wastewater system. Such investigations may include closed circuit television inspection of sewer lateral lines and privately owned service lines. These inspections are used to determine contributing factors causing the blockage or overflow, such as defective infrastructure, accumulated roots and/or debris; and to seek visual evidence of FOG waste accumulation between the site of the stoppage or overflow and upstream FSEs. FSEs found to have contributed to a sewer blockage, SSO, obstruction, interference, damage, or any other impairment to the City’s sewer facilities, to the operation of those facilities or to have caused any sewer system interferences resulting from the discharge of wastewater or waste containing FOG or other not approved constituents, may be ordered to install and maintain a grease interceptor and/or wastewater monitoring devices, and may be subject to a more restrictive plan to abate future problems. Furthermore, sewer lateral failures and SSOs caused by FSEs alone or collectively, are the responsibility of the private property owner or FSE(s) and they shall be liable for all costs required to clean or repair the facilities together with expenses incurred by the City to resume normal operations. If the City must act immediately to clear a sewer blockage or contain and clean up an SSO caused by blockage of a private or public sewer lateral or system serving an FSE, or acts at the request of the property owner or operator of the FSE, the City’s costs for such abatement shall be entirely borne by the property owner or operator of the FSE, and may constitute a debt to the City.

Chapter 7 Drawing Submittals The City ensures that all plumbing related components of a new, modified or existing FSE are properly addressed. Approval of required plans shall be required prior to the City issuing a construction permit. The City requires that plans be submitted on all projects that require alteration, removal, or addition of any type or size of plumbing fixtures. The purpose of the plans is to verify that all development requirements established in the City’s Municipal Code and included in the adopted conditions of approval for the project are addressed. Plans for proposed new or existing FSEs will be required and shall be in compliance with the requirements included in the City’s Municipal Code. The City may require facility site plans, mechanical and plumbing plans, and other details to show the sewer locations and connections for its facility or premises. Plan check submittals for review of an existing or proposed grease interceptor, monitoring and metering facilities, and/or operating procedures shall be in a form and contain content as required by the City. Where it is determined that installation of grease removal equipment is required, the Director of Public Services or the Director’s designee shall approve the size of the grease removal equipment. The review of the plans and procedures shall in no way relieve an owner or operator of an FSE of the responsibility of modifying the facilities or procedures in the future, as necessary to meet the requirements of the City’s FOG Control Program, City Municipal Code or any additional requirements of other regulatory agencies.



June 2009

8-1

Chapter 8 Public Outreach It is the expectation of the City that efforts to keep FOG from entering into the wastewater system can be achieved with public education and through the common interest in preventing health hazards and damage to homes and businesses. The City’s Fats, Oils, and Grease Control Program documents its current activities which serve to facilitate the maximum beneficial public use for the City’s sanitary sewer system while preventing blockages of the sewer lines and reducing the adverse affects on sewage treatment operations resulting from discharges of FOG into the system. The primary focus of the City’s FOG Control Program has been on source control with a concentrated effort in educating FSE staff on the negative impacts of putting FOG into the wastewater collection system. During the regularly performed site inspections, City staff provides informative and practical suggestions for reducing the quantity of FOG discharged into the City’s wastewater collection system, engaging FSE staff in reducing FOG related SSOs. During the inspections, City staff provides FSE owners and staff with information regarding BMPs, which include simple and effective practices that an FSE can implement to prevent and reduce the quantity of FOG discharged into the sanitary sewer system. Routine inspections performed by City staff provide the City an opportunity to reiterate the importance of limiting FOG discharge into the City’s wastewater collection system and reduce the potential of SSOs due to excessive FOG. To date, the City’s efforts to educate FSE staff has been effective in attaining the desired results from the FSEs.

From your Department of Public Services

Help us protect our environment!

Grease, oil, and fat should go from

the Pan...

...to the Can.

Never pour grease, cooking oil, or fat down the sink.

They can clog drains and cause sewer pipes to back up.

Cool down your cooking oil, grease, and fat - pour them into a container

with a secure lid.

Trash the can – not your pipes!

Wipe out pots and pans with a paper towel before doing dishes – you will use less soap

and decrease clogs.

Dispose of food scraps in the trash – not down garbage disposals, drains, or toilets.

Appendix G – Public Outreach

Sample Postcard Text for Residents Dear Resident, You are receiving this message because your neighborhood has recently experienced a sanitary sewer spill related to a build-up of fats, oils, and grease in the sewer pipes. Cooking grease coats pipelines much like fatty foods clog human arteries. The grease clings to the insides of the pipe, eventually causing blockages and potential sewer spills. By following a few simple steps, you can help prevent costly sewer spills in the future.

• Pour your cooking oil (this includes salad oil, frying oil and bacon fat) into an old milk carton, frozen juice container, or other non-recyclable package, and dispose of it in the garbage.

• Wipe dishes and pots that are coated with greasy leftovers (butter, peanut butter, etc.) with a disposable towel prior to washing or placing in the dishwasher.

• Place food scraps and fat trimmings from meat in a trashcan.

If you have questions, please contact us at 619.522.7380. Sincerely, Director of Public Services
