5 Introduction A. Sewer System Management Plan In May 2006, the State Water Resources Control Board (SWRCB) adopted Statewide General Waste Discharge Requirement Order No (WDR Order) which requires publiclyowned treatment facilities to develop and implement a Sewer System Management Plan (SSMP). The purpose of the SSMP is to facilitate proper funding and management of sanitary sewer systems. SSMPs must include provisions to provide proper and efficient management, operation, and maintenance of sanitary sewer systems, while taking into consideration risk management and cost benefit analysis. Additionally, each SSMP must contain a spill response plan that establishes standard procedures for immediate response to an sanitary sewer overflows in a manner designed to minimize water quality impacts and potential nuisance conditions. An SSMP is required for sanitary sewer collection systems comprised of more than one mile of pipe that convey untreated wastewater to a publicly owned treatment facility. There are eleven specific SSMP elements that are required to be completed and certified between 2008 and The Central Valley Region of the Regional Water Quality Control Board (RWQCB) adopted the State Board s requirements and due dates. This SSMP was prepared by East Bay Municipal Utility District (EBMUD) staff. The SSMP is in compliance with requirements of the Central Valley Region of the Regional Water Quality Control Board and the State Water Resources Control Board. The structure of this SSMP follows the WDR Order. B. Sanitary Sewer System Facilities EBMUD (the District) operates three wastewater facilities that serve the Camanche North Shore Recreation Area (CANS) and Pardee Recreation Area (PARA) in Amador County and Camanche South Shore Recreation Area (CASS) in Calaveras County. The sewer system at CANS consists of 5.4 miles of gravity sewers, 0.5 miles of force main, 154 sewer laterals (one mile) and four sewer lift stations. The sewer system at CASS consists of 7.4 miles of gravity sewers, 1.6 miles of force main, 263 sewer laterals (2.5 miles) and seven sewer lift stations. The sewer system at PARA consists of 1.5 miles of gravity sewers and 105 sewer laterals (0.4 miles). The sewer main lines range from 4 inches to eight inches in diameter, the sewer laterals are 4 inches in diameter and the force mains are 3 or 4 inches in diameter. Maintenance and repair of the sewer collection systems including main lines, force mains, laterals and lift stations are the responsibility of EBMUD. The maintenance of the sewer laterals from the connection point cleanout to the residence is the responsibility of resident. Moke_SSMP 2010.doc v

19 Effective Date: Feb. 2, 2010 Document Name: E4 Operations and Maintenance Program The GIS database for the collection system is currently stored on a standalone PC workstation at G:\projects\WasteWater\mxd\InterceptorData.mxd and routinely backed up on a network server. Printouts from the GIS database are located on EBMUD s internal online document storage system (DOX: Map Updates System maps are reviewed for accuracy and field verified to ensure current conditions are depicted at least once per year. Maps are updated as required based on this review. Maps are also updated any time new facilities are added or existing facilities are modified. Updates to the master map and map book set will continue to be edited by hand until the set can be replaced by a fully developed GIS map system. 4.2 Preventive Maintenance EBMUD conducts routine maintenance and preventive maintenance (PM) activities by dedicated EBMUD Wastewater Maintenance Worker staff for its sewer collection systems Computerized Maintenance Management System (CMMS) A customized CMMS developed by EBMUD is called the Asset Information Management System (AIMS) ( and is used by Pardee Section Wastewater Maintenance staff to: Request maintenance services and manage both planned and unplanned maintenance activities Track equipment inventory and maintenance Plan and prioritize maintenance work Maintain timely and accurate activity records which can be easily accessible and used for appropriate analysis and reporting The CMMS covers EBMUD s entire Mokelumne wastewater collection and treatment systems. Components specific to the sewer collection systems included in the CMMS are: Collection System Mains and Laterals Sewer Lift Stations Manholes Moke_SSMP 2010.doc Page 9 of 33

20 Effective Date: Feb. 2, 2010 Document Name: E4 Operations and Maintenance Program Cleanouts Other utilities that impact or may be impacted by their operation and maintenance or operation and maintenance of EBMUD s collection system Preventive Maintenance, Inspections and Activities Pardee Wastewater Maintenance Worker staff performs routine inspections, cleaning, and other PM activities for all wastewater collection, lift stations and treatment systems. The procedures are documented in the O&M Plan and work orders are managed and tracked by the AIM PM System and the GIS based Map System. The O&M Plan describes the priority of PM work orders based on criticality and urgency criteria from 24 hours (emergency/safety) up to 180 days (secondary non-critical or minor). Intermediate priority needs include regulatory, process/essential, and secondary critical. Inspection and testing, both routine and non-routine, are conducted to preserve equipment and facilities from failure and deterioration that could lead to sewer system overflows. If the inspections and testing indicate accumulation of debris and other items of concern in the sewer main line(s), additional condition assessment inspections may be conducted as part of the R&R Plan (see below). Upon completion of a capital improvement project, inspection and testing may be revised to include smoke testing, video inspections, leak check of manholes, root treatment, and/or inflow assessments. The sewer mains have on occasion exhibited problems with debris accumulation that could lead to sewer system overflows (SSOs), thus would be scheduled to be cleaned out. Based on inspection and testing results, corrective maintenance is also initiated and tracked through AIMS. EBMUD has a routine sewer main and lateral cleaning program including the equipment and personnel required to perform sewer cleaning. EBMUD performs cleaning based on a defined schedule with the goal of completing each system in its entirety within three years, and hot spots with greater cleaning and treatment, as warranted, as frequently as once per month. Cleaning needs are varied from location to location and may include hydro-jetting, mechanical rodding, vacuuming, root treatment and removal, and flushing. Cleaning schedules have been derived based on conventions of best management practices for O&M of sewer collection systems within the regional industry as well as an extensive history of practical operation of the wastewater collection systems at the recreation areas.

21 Effective Date: Feb. 2, 2010 Document Name: E4 Operations and Maintenance Program 4.3 Rehabilitation and Replacement (R&R) Plan The Upcountry Utilities Infrastructure Master Plan (UUIMP) establishes a long-term strategy to address rehabilitation and repair needs for EBMUD s upcountry infrastructure utilities including wastewater collection, treatment and disposal systems. Its objectives are to render a current assessment of facility issues, prioritize rehabilitation and repair needs, and provide a rational basis for justifying capital funding for critical upcountry improvements. The UUIMP is updated every two years to ensure that upcountry infrastructure issues remain current. It is intended to be used as a planning resource for regular updating of the 10-year plan for Remediation Program. The repair and rehabilitation needs for upcountry wastewater facilities have historically been addressed through the administration of the Remediation Program Remediation Program The Remediation Program maintains District facility compliance with federal, state and local environmental regulations, including new and anticipated requirements. This program funds capital improvement needs for EBMUD s wastewater systems Preventative and Corrective Maintenance Procedures The R&R Plan is driven by EBMUD s Upcountry Wastewater Systems O&M Plan. The Preventative and Corrective Maintenance Programs for the collection systems, lift stations, and wastewater treatment and disposal facilities are described in the O&M Plan Budget EBMUD develops a 5-year Capital Improvement Program (CIP) and an annual operating budget. The CIP and operating budget are prepared as part of EBMUD s biennial budget process. Moke_SSMP 2010.doc Page 11 of 33

22 Effective Date: Feb. 2, 2010 Document Name: E4 Operations and Maintenance Program Capital The long-term capital budget consists of funds allocated for projects to rehabilitate and repair the wastewater facilities under the CIP. Project prioritizations are based on the results of the UUIMP which includes SSMP s Element 4 O&M Program, Element 5 Design and Performance Standards and Element 8 System Evaluation and Capacity Assurance Plan. The CIP has funds available for short-term unplanned projects. These short-term and long-term projects will be managed through the Remediation Program, the Recreation Areas Program and the Supply Reservoirs Program. The goals of these programs are to: Ensure public and employee safety Surpass environmental and regulatory requirements Enhance infrastructure reliability Ensure the wastewater systems meet current and future facility capacity needs and are in compliance with current standards Operating The operating budget consists of resources necessary to operate and maintain the collection system. Such resources include staff, energy, chemicals, parts and materials, vehicles, fuel, and outside contracts. Labor costs and other expenses are tracked continuously. The budget for these resources is established based on the District s salary schedule and staffing plan, and historical data, trending/projections, and inflation factors Resources The main source of revenue for operating, maintaining, and repairing the collection system and treatment and disposal facilities will come from bonds and revenue. The improvements constructed will be paid, in part, by revenue collected from the operation of the recreation areas and lease rates in the mobile home parks. Moke_SSMP 2010.doc Page 12 of 33

27 Effective Date: Aug. 2, 2010 Document Name: E5 Design and Construction Standards 5.2 Inspection & Testing Standards EBMUD s standard specifications include methods and requirements for testing and accepting the construction of pipe, manhole, cleanout, and sewer laterals in the sewer collection system. Prior to acceptance, EBMUD requires inspection by CCTV to detect obstructions or defects in the sewer collection system. The specifications also include methods and requirements for testing the mechanical and electrical equipment and the functionality of the sewer lift stations. Construction management and inspection during construction of new, rehabilitated or repaired projects is performed by EBMUD staff. Pardee Wastewater Maintenance staff performs routine inspections and cleaning activities for all wastewater collection systems and lift stations. The procedures are documented in the O&M Plan. Inspection and testing, both routine and non-routine, are conducted to preserve equipment and facilities from failure and deterioration that could lead to sewer system overflows. If the inspections and testing indicate accumulation of debris and other items of concern in the sewer main line(s), additional condition assessment inspections may be conducted as part of the R&R Plan (see Element 4.3) or as documented in the Master Plan.

28 Effective Date: Feb. 2, 2010 Document Name: E6 Emergency Response Plan 6.0 Emergency Response Plan The EBMUD overflow emergency response program consists of plans and procedures to protect public health and the environment and satisfy strict regulatory reporting requirements. Guidelines and procedures have been established for notification and reporting, chain of communication, and appropriate response, mobilization, abatement, and mitigation standards and best management practices. These plans and procedures are documented in the Pardee Area Control Center (ACC) Emergency Notification Guidelines, the Operations and Maintenance (O&M) Plan and the Sanitary Sewer Overflow Prevention & Response Plan. 6.1 Initial Notification The EBMUD may receive information regarding potential SSOs from the ACC, EBMUD or contractor employees, or the general public. The Oakland Control Center (OCC) may also receive calls when the ACC requires backup coverage. Upon confirmation of the SSO through visual verification by EBMUD first responders, staff will contact and request appropriate resources to be dispatched and initiate the communication chain of command listed in the Emergency Notification Flowchart shown below. The EBMUD Regulatory Compliance Division staff or the designated standby emergency person is responsible for notifying the appropriate regulatory agencies within the mandated reporting time periods. Standby procedures are documented in the Regulatory Compliance Standby binder operating procedures. 6.2 Response Mobilization and Public Notification Upon determining the level of response required, all necessary appropriate actions shall be taken to contain and control the SSO, mitigate public and environmental impacts, and document the SSO. The Shift or Standby Supervisor is responsible for dispatching additional persons and equipment to assist with the response. If the size and extent of the spill is beyond EBMUD s capability to respond in a timely manner, contractors are available to dispatch a variety of cleanup equipment and support personnel. If the SSO is in the vicinity of a swimming, bathing, boating or any other recreation area where the public health could be affected, public notification/posting procedures are described by the EBMUD Mokelumne Watershed and Recreation Division. The affected areas may be restricted or closed to the public and appropriate warning signs posted. The Mokelumne Watershed Rangers are responsible for security and will coordinate with the EBMUD Public Affairs if Moke_SSMP 2010.doc Page 18 of 33

29 Effective Date: Feb. 2, 2010 Document Name: E6 Emergency Response Plan additional public and/or other media communication is required (see Element 11 SSMP Communication Program). 6.3 SSO Abatement and Impact Mitigation Plan SSO response and cleanup procedures are outlined in the Emergency Notification Guidelines, the O&M Plan, and the Sanitary Sewer Overflow Prevention & Response Plan. Types of corrective actions are described to assess the SSO, stop the upstream source temporarily until cleanup and repairs can be completed, contain spillage materials while cleaning the point of blockage, contain further migration if sewage has reached surface waters, and strategies for pumping the spillage back into the sewer system or tank truck. The level of response will depend whether the spillage has migrated or has a high potential to migrate to surface waters, contaminate drinking water, or threaten public health. For overflows that have migrated to surface waters or threaten to migrate to surface waters, the procedures specify immediate actions to stop the source and then contain the sewage. The most effective actions which will provide the most immediate cessation of spillage flow should be considered first, such as blocking a manhole cover or building an earthen berm or using sandbags. Documentation of the site conditions is necessary during the initial assessment phases by the first responders, which is needed to report to regulatory agencies. Estimates of spillage flow rates and when the overflow began are calculated to determine the appropriate cleanup methods and required equipment and containers necessary to quickly recover the sewage. Time permitting, environmental samples are collected to document the extent of environmental and public health impacts. Sample collection and sample handling procedures are described in the plans, which may be used for litigation or regulatory purposes. Biohazard safety and personal protection procedures are specified in the emergency response plans as required by Workplace Health and Safety Required Safety Practices. Refresher training is provided annually and as necessary during daily tail gate safety meetings. Environmental compliance and first responder refresher training are provided frequently on an as-needed basis, but at a minimum, annually. Moke_SSMP 2010.doc Page 19 of 33

31 Effective Date: Feb. 2, 2010 Document Name: E7 FOG Control Program 7.0 FOG Control Program EBMUD owns and maintains the sewer systems which collect and transport domestic wastewater from all connections to treatment, storage, and disposal systems at three recreation areas. Implementation of the Sanitary Sewer Operation, Maintenance, Overflow Prevention, and Response Plan (SSOPP, Nov. 2002) consists of conducting ongoing preventative maintenance, inspections, and corrective maintenance as required in each waste discharge permit. Discharge of fats, oils, and grease (FOG) into the collection system are listed as prohibited materials that cause obstruction of flow or could damage the sewerage facilities. This FOG program consists of enforcement and public education outreach at EBMUD s recreation areas. 7.1 Source Identification Wastewater discharges from residential mobile home park sites, common area use sites, and one food service facility at each recreation area (snack bar/café) are potential sources for causing grease-related sanitary sewer overflows (SSOs) and blockages in the sewer collection systems. Source control measures are limited to appropriate level of inspections and maintenance upstream of sewer hot spot areas of blockages and public outreach. 7.2 Legal Authority for the FOG Program The Pardee Recreational Vehicle (RV) Park Site Use Conditions, Camanche South Shore Longterm RV Park rules and Regulations, and Camanche North Shore and South Shore Mobile Home Park Rules and the EBMUD Watershed and Recreation Rules and Regulations (Board Resolution No ) each specifically address prohibitions of any non-sewage materials into the collection system or any action which may cause, threaten to cause or is capable of causing damage or impacting the operation of the sewerage facilities. The resolution provides legal authority for EBMUD to take all necessary steps to adequately maintain, operate, and prevent spills from its sanitary sewer collection systems, including, but not limited to implementing a FOG program. Each facility s Waste Discharge Requirements (WDRs) also require maintaining the system in good working order, operating as efficiently as possible and taking all reasonable steps to minimize/prevent any adverse impact to the waters of the state.
