9 Introduction Background This Sewer System Management Plan (SSMP) has been prepared in compliance with the State Water Resources Control Board (SWRCB) Order : Statewide General Waste Discharge Requirements for Sanitary Sewer Systems (GWDR), as revised by Order No. WQ EXEC on February 20, The GWDR prohibits sanitary sewer overflows (SSOs), requires reporting of SSOs using the statewide electronic reporting system, and requires the development and implementation of a Sewer System Management Plan (SSMP). This SSMP has also been prepared to meet the requirements of the San Francisco Bay Regional Water Quality Control Board (RWQCB). This SSMP has been prepared by the City of Berkeley (City) with assistance from Larson Consulting. Organization of SSMP The structure of this document follows the section numbering and nomenclature used in the GWDR. The SSMP includes eleven sections, as follows: 1. Goals 2. Organization 3. Legal Authority 4. Operation and Maintenance Program 5. Design and Performance Provisions 6. Overflow Emergency Response Plan 7. Fats, Oils and Grease (FOG) Control Program 8. System Evaluation and Capacity Assurance Plan 9. Monitoring, Measurement, and Program Modifications 10. SSMP Audits 11. Communication Program Sanitary Sewer System Overview The City provides sanitary sewer service to a population of approximately 105,000 people located within its 10.5 square mile service area. The City s wastewater collection system includes approximately 258 miles of main sewer lines, 7,200 manholes, and 32,000 lower laterals (from the curb/easement boundary to the sewer main in the public right of way) with a total length of approximately 130 miles. The maintenance of private lateral (upper lateral) is the responsibility of the property owner. There are seven sewer pump stations (all located within the Marina and Aquatic Park). The University of California Berkeley Campus discharges into the City s sewer system. In addition there are several small sewer basins located within the Cities of Albany, Kensington, and Oakland City of Berkeley Introduction Page-1

10 that discharge into the City s wastewater collection system. Each satellite is responsible for the management, operation, and maintenance of their respective sanitary sewer facilities. The City s wastewater collection system discharges into the East Bay Municipal Utility District (EBMUD), Special District No. 1 interceptor system located along the City s western and southern (Adeline Street) boundaries. Historical Perspective A Cease and Desist Order issued by the San Francisco Bay Regional Water Quality Control Board in 1986 requiring the seven East Bay agencies that discharge to EBMUD, including the City of Berkeley, to eliminate overflows and to upgrade their sewer systems in order to reduce the quantity of infiltration/inflow being discharged to EBMUD. In response to the Cease and Desist Order, the City began a long-term Capital Improvement Program for sewer replacement and rehabilitation. The objectives of the program were to eliminate overflow conditions, increase sewer capacity and to upgrade and replace the components of the aged or deteriorated wastewater collection system. The City has upgraded by replacement or rehabilitation approximately 170 miles of it sewer mains (63%) and 68 miles (52%) of its lower laterals as of March The City s Capital Improvement Master Plan has been updated periodically to include a Proactive Back Line Sewer Replacement Program that is focused on public sewer mains located on private property in order to protect open creeks and to include an ongoing cyclic replacement program.

The City will act to amend its Municipal Code to provide access for maintenance, inspection, or repairs for portions of the sewer service lateral owned or maintained by the City by July 1, The City will pursue agreements with its satellite sewer systems with the goal of establishing limits on the peak flows discharged to the City s sewer system facilities following the establishment of capacity flow limits for the City s discharge to EBMUD. The capacity flow limits are anticipated in 2012 at the earliest. City of Berkeley Page 3-2

23 Section 4. Operations and Maintenance Program 4.1. Introduction This section of the SSMP provides an overview of the City s sewer system operations and maintenance (O&M) program Regulatory Requirements for Measures and Activities (O&M) Element of SSMP RWQCB Requirement (Measures and Activities): (a) Maintain up-to-date maps of the wastewater collection system facilities; (b) Allocate adequate resources for the operations, maintenance and repair of the collection system; (c) Prioritize preventive maintenance activities; (d) Identify and prioritize structural deficiencies and implement a program of short-term and long-term actions to address them; (e) Provide contingency equipment to handle emergencies, and spare/replacement parts intended to minimize equipment/facility downtime; (f) Provide training on a regular basis for staff in collection system operations, maintenance, and monitoring; and (g) Implement an outreach program to educate commercial entities involved in sewer construction or maintenance about the proper practices for preventing blockages in private laterals. This requirement can be met by participating in a region-wide outreach program GWDR Requirement (Operations and Maintenance): The summarized requirements for the Operations and Maintenance Program are: 1. Maintain an up-to-date map of the sanitary sewer system, showing all gravity line segments and manholes, pumping facilities, pressure pipes and valves, and applicable storm water conveyance facilities; 2. Describe routine preventive operation and maintenance activities by staff and contractors, including a system for scheduling regular maintenance and cleaning of the sanitary sewer system with more frequent cleaning and maintenance targeted at known problem areas. The preventative maintenance (PM) program should have a system to document scheduled and conducted activities, such as work orders; 3. Develop 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 City of Berkeley Page 4-1

24 schedule for implementing the short-term and long-term plans plus a schedule for developing the funds needed for the capital improvement plan; 4. Provide training on a regular basis for staff in sanitary sewer system operations and maintenance, and require contractors to be appropriately trained; and 5. Provide equipment and replacement part inventories, including identification of critical replacement parts Section Organization The majority of the RWQCB and GWDR requirements for the Operations and Maintenance Program element of the SSMP are in agreement. The following presents the GWDR requirements first. The RWQCB requirements that are not satisfied by the response to the GWDR requirements follow at the end of this section Collection System Mapping The City has a geographical information system (GIS) that includes the information for its wastewater collection system assets. The GIS information is available to appropriate City staff. The field crews use hard copy maps called Block Books. The hard copy maps are updated annually. Corrections that are identified by the field crews are entered on a single map set that is maintained in the office. Corrections and new facilities are incorporated into the maps during the annual update Preventive Maintenance The elements of the City s sewer system O&M Program include proactive, preventive, and corrective maintenance of gravity sewers, and periodic inspection and preventive maintenance for the pump stations. The details of the City s O&M programs are described in this section Gravity Sewers The City proactively cleans its sewer system every six years, and it preventively cleans sewers with a history of problems every 1, 3, 6, or 12 months. Two sewer cleaning crews are assigned to these activities. The City s standard operating procedure for sewer cleaning is included as Appendix 4-A. The City uses closed circuit television (CCTV) for troubleshooting and to identify the causes of blockage and SSOs. One CCTV crew is assigned to these activities. The City has one sewer repair crew to correct problems identified by the CCTV or sewer cleaning crews. Repairs are completed in priority order. The wastewater collection system staff maintains a list of known structural deficiencies. This list is maintained in priority order. High priority structural deficiencies are repaired as soon as possible by the City s sewer repair crew or by an outside contractor. Gravity sewer preventive maintenance is currently scheduled using lists of line segments and lower laterals that require more frequent cleaning. System-wide gravity sewer maintenance is scheduled using Block Maps. Completed gravity sewer and lower lateral maintenance is recorded using work orders. The completed work is recorded in the City s computerized maintenance management system (CMMS) starting in March City of Berkeley Page 4-2

25 Pump Stations The City conducts a weekly operational inspection of its pump stations. The wet well is cleaned every four months. Mechanical and electrical equipment preventive maintenance is scheduled annually Non-Routine Maintenance Non-routine maintenance activities include investigation and response to any complaints regarding a manhole overflow, missing or shifted manhole covers, manhole covers that are excessively noisy, residential plumbing troubles, pump station malfunction, unexpected sewer odor, etc. Sewer complaints received by the Public Works Department are investigated and appropriate actions are taken to resolve the source of the problem Rehabilitation and Replacement Plan The City s rehabilitation and replacement program is driven by its ongoing gravity sewer condition assessment effort based on CCTV. The City has rehabilitated approximately 170 miles of gravity sewers (63%) and 68 miles of lower laterals (52%). The City has budgeted a total of $1.13 million for FY 2010 and FY 2011 for CCTV inspection. This rate of expenditure is expected to result in completing the inspection of all of the older gravity sewers within five years. The information gathered during the condition assessment will be used to select gravity sewers for repair/ rehabilitation/replacement. The City has an annual sewer rehabilitation and replacement program to rehabilitate or replace the portions of its wastewater collection system where conditions warrant. The projects that are included in the City s Capital Improvement Program are shown in Appendix 4-B. The funds that support the Capital Improvement Program come from the City s Sewer Fund. The sewer fund is an enterprise fund and sewer fees are established to meet projected needs Training Program City Staff The City uses a combination of in-house classes; on-the-job training; and conferences, seminars, and other training opportunities to train its wastewater collection system staff. In most cases, equipment and operations training is initially provided by the vendor or manufacturer of the equipment. Ongoing technical training is provided through on-the-job training and rotation among the different maintenance crews and equipment. The City also relies on regional and statewide training available through seminars and conferences. The training resources are shown on Table Staff Contracted for City Projects The City s contract language requires contractors working in the wastewater collection system to provide training for their employees regarding the potential to cause SSOs. The City construction specifications require that all contractors and subcontractors be experienced with sanitary sewer work and that they fully comply with all laws, regulations, and standards governing sewer work, sanitation, and public health.

Wear proper personnel protective equipment (PPE). 2. Fill the water tank at or near the first jobsite. 3. Determine and confirm location of upstream and downstream manholes (use street addresses, if possible). 4. Look for any overhead utilities that may come into contact with the vacuum boom during the cleaning operation. 5. Set up proper traffic control by placing traffic signs, flags, cones and other traffic control devices. 6. Move the cleaning unit into the traffic control so that the hose reel is positioned over the manhole. 7. Open the manhole and use the gas detector to determine if it is safe to proceed with the cleaning operation. 8. Install the Warthog nozzle on the hose. Cleaning Operation 1. Insert the debris trap. 2. Start the auxiliary engine. 3. Lower the hose, with a guide or roller to protect the hose, into the manhole and direct it into the sewer to be cleaned. 4. Start the high pressure pump and set the engine speed to provide adequate pressure for the sewer cleaning operation. 5. Open the water valve and allow the hose to proceed up the sewer. The hose speed should not exceed 3 feet per minute. 6. Allow the hose to proceed 25% of the length of the sewer and pull the hose back. 7. Observe the nature and the quantity of debris pulled back to the manhole. 8. If there is little or no debris, allow the hose to proceed to the upstream manhole. 9. If there is moderate to heavy debris, clean the remaining portion of the sewer in steps not to exceed 25% of the length of the sewer. 10. Open the upstream manhole and verify that the nozzle is at or past the manhole. 11. The sewer has been adequately cleaned when: Successive passes with a cleaning nozzle do not produce any additional debris; and The sewer is able to pass a full size, six-wire skid ( proofer ) for its entire length. 12. Determine the nature and quantity of the debris removed during the cleaning operation. Use the codes in Table 4-A-1 to report the nature and quantity of debris.

35 Section 5. Design and Performance Provisions 5.1. Introduction This element of the SSMP presents the City s Design and Construction Standards Regulatory Requirements for Design and Performance Provisions Element of SSMP (Design and Construction Standards) The summarized requirements for the Design and Performance Provisions element of the SSMP, which includes Design and Construction Standards, are: RWQCB Requirement The Collection System Agency shall identify minimum design and construction standards and specifications for the installation, rehabilitation and repair of new and existing sewer systems. The Collection System Agency must evaluate if the existing design standards are appropriate and up-todate. If the Collection System Agency believes its current standards are appropriate, the Collection System Agency can refer to existing documentation. The Collection System Agency shall identify procedures and standards for inspecting and testing the installation of new sewers, pump stations, and other appurtenances; and for rehabilitation and repair projects. As with design and construction standards, the SSMP should refer to existing documentation if standards for inspection and testing are already in place GWDR Requirement The Enrollee must have design and construction standards and specifications for the installation of new sewer systems and for the rehabilitation and repair of existing sewer systems. The Enrollee must also have procedures and standards for inspecting and testing the installation of new sewers, pump stations, and other appurtenances; and for rehabilitation and repair projects Standard Specifications for Wastewater Facilities The City s standards pertaining to the design, construction, and inspection of gravity sewer systems, sewer force mains, and other facilities to be operated and maintained by the City consist of the standards included in Appendix 5-A, the California Plumbing Code, the City of Berkeley/East Bay Municipal Utility District (EBMUD) Standard Specifications, and the Standard Specifications for Public Works Projects by Public Works Standards, Inc., also known as the Greenbook. City of Berkeley Page 5-1

36 Appendix 5-A: Design Standards for Sanitary Sewers Sewer Mains General The City is fully developed (e.g. there are no vacant lots) and the majority of the current and future sewer system design and construction projects consist of rehabilitation of the existing sewers. The City will use the Greenbook Standard Specifications for Sanitary Sewer Design for the design of its rehabilitation projects. The design of new sewers shall conform to the City of Berkeley Design Standards, East Bay Municipal Utility District (EBMUD) Standard Specifications, and the Greenbook Standard Specifications for Sanitary Sewer Design. Materials Gravity sewers and laterals shall be Cast Iron Pipe, Extra Strength Vitrified Clay Pipe (VCP) or High-Density Polyethylene (HDPE) pipe, with a minimum standard diameter ratio (SDR) of 21. Other materials may be used based on site conditions. Sewer force mains shall be Ductile Iron pipe or HDPE SDR-17. Use the same pipe material from structure to structure. Alignment Horizontal Conform to the State of California, Department of Health Services, Criteria for Separation of Water and Sanitary Sewer. Horizontal separation from storm drains or other sewer mains shall be a minimum of five feet clear between pipes except at crossings. Horizontal separation from other utilities, such as gas, underground electric, underground television cable, etc., shall be a minimum of four feet clear between the pipes except at crossings. Horizontal curves in gravity sewer mains are not allowed. All sewer main trenches that are parallel to and deeper than the footing of any adjacent structure must be at least 45 degrees from the footing as required in the Uniform Plumbing code. Vertical Conform to the State of California, Department of Health Services, Criteria for Separation of Water and Sanitary Sewer. Provide a minimum of six inches of vertical separation from storm drains or other utilities, such as gas, underground electric, underground television cable, etc. When the minimum cannot be maintained, plans shall indicate installation of felt expansion material or equivalent between facilities. To protect the sewer main from distorting under extreme loads, other measures, such as concrete encasement or ductile iron pipe, may be utilized. Vertical curves in gravity sewer mains are not allowed. City of Berkeley Page 5-2

37 Pipe Sizing Criteria Design Flow The design flows shall be based on the following criteria: A. The average daily wastewater flow, in gallons per day (GPD) shall be: Single Family Residential 280 GPD per unit Multi-Family Residential 200 GPD per unit Commercial 1,750 GPD per net acre Industrial 2,450 GPD per net acre School 20 GPD per student Park and Open Space 170 GPD per net acre B. The capacity of the sewer shall be 3 times the average daily wastewater flow from a. above. C. Sewers that connect to existing sewers shall be designed to carry infiltrated water in addition to the volumes above. Design Velocity Gravity sewers shall maintain a minimum velocity of 2 fps when the pipe is flowing full. For the analysis of existing or proposed sewer systems, use the Manning Equation. Manning s Equation is: where: V is the velocity of flow measured in feet per second. r s represents the hydraulic radius of the wetted cross-section of the pipe measured in feet. It is obtained by dividing the flow area by the length of the wetted perimeter. represents the slope of the energy gradient. It is numerically equal to the slope of the invert and the hydraulic surface in uniform flow. A represents the cross-sectional area of the flowing water in square feet. Q is the quantity of flow measured in cubic feet per second. n is the coefficient of roughness which is used in Manning s Equation to calculate flow in a pipe. The following Manning s roughness coefficients shall be applied for all design: For new pipe: n = For existing pipe: n = Pipe Size Gravity sewer pipes shall be designed to flow 75% full at the future peak flow. City of Berkeley Page 5-3

38 Minimum Pipe Size The minimum main sewer pipe size is 8-inch diameter. The minimum lower lateral pipe from a single-family house is 4-inch diameter. The size of the lower lateral pipe serving an apartment building or a large complex shall be determined by estimating the peak flows and using the peak flow to size the pipe. This is accomplished by counting units and plumbing fixtures as the basis for the flow estimate. Minimum Pipe Slope The minimum pipe slope for gravity sewers is listed as follows: Pipe Size, inches Minimum Slope, ft/ft Sewer Main and Lateral Pipe Trench Cover and Bedding Cover is the distance from the top of the pipe to final finished grade measured directly over the pipe. Minimum cover for all sewer mains and laterals shall be 36 inches. Where cover is less than 36 inches, special construction techniques must be approved such as concrete encasement, use of ductile iron pipe, concrete cap over the trench or the use of controlled density fill (CDF). Compaction for the new sewer trench must have a relative compaction test of 90% in unpaved area and a minimum of 95% relative compaction test in the vehicular traffic area. Sewer pipe bedding shall be imported and a mixture of combined mineral aggregates. Trench cover or a backfill material shall conform to either its native material or an imported material to compaction test. Connection to an Existing Sewer Main A. Connect new mains to existing at existing manholes or by constructing a new manhole over the point of connection. Elevations of mains connecting to existing sewer mains shall be as follows: Side sewer mains connecting to an existing main at an angle of 30 degrees or greater shall be at least 0.1 foot higher than existing. Connect sewer mains so that the crown of the smaller main is no lower than the crown of the larger main. B. Where laterals are the same size as the main, connection must be made with a manhole. Use a wye for all other lateral connections. City of Berkeley Page 5-4

39 Manholes and Rodding Inlets A manhole is required at every horizontal or vertical change in alignment. Maximum distance between manholes is 300 feet. A manhole is required at the end of every main in excess of 200 feet in length. Rodding inlets may be installed in lieu of manholes at the end of a sewer main where the distance is less than 200 feet to the nearest manhole and the main size is 10-inch or less. The manhole shall be designed such that the angle in the horizontal plain between the downstream and any incoming sewer is a minimum of 90 degrees. Stubs provided out of manholes for future extensions shall have rodding inlets provided when more than one length of pipe is installed or where service laterals are connected to the stub. Private sewer mains must connect to the public main at a manhole. Standard drop manhole installations are required when the difference in elevation between the incoming and outgoing sewer is greater than 2 feet. Manholes shall have a minimum barrel of 48 inches for sewer pipe 30 inches and less. Sewer Laterals The minimum sewer lateral size is 4-inch. The minimum slope of sewer laterals is 2 percent or ¼-inch per foot for 4-inch laterals. All sewer laterals, from property line or edge of easement to the point of connection with the main line or a manhole, shall generally be perpendicular to the curb alignment or easement and will have an angle of intersection with the downstream section of sewer of no less than 90 degrees. No lateral alignments adverse to the flow of the main will be permitted. Lateral connections must be accessible and easy to locate. Abandonment A. Any existing sewer mains and service laterals that will not be used shall be abandoned and the following must be noted on the plans: Sewer mains that are to be abandoned shall be securely closed at all pipe ends with a cap or at manholes with a concrete plug. Further, mains 12-inch and larger must be filled with a sand slurry or other suitable material. B. Manholes to be abandoned shall require removal of upper portion (down to 3 feet from finish grade) and perforation of the bottom either by using jack hammer or any tools or equipments and shall be filled with backfill material and compacted to 90 percent relative compaction.

41 Section 6. Overflow Emergency Response Plan 6.1. Introduction Purpose The purpose of the Overflow Emergency Response Plan (OERP) is to support an orderly and effective response to sanitary sewer overflows (SSOs). The OERP provides guidelines for City personnel to follow in responding to, cleaning up, and reporting SSOs that may occur within the City s service area Regulatory Requirements for OERP Element of SSMP RWQCB Requirement The collection system agency must develop an overflow emergency response plan that provides procedures for SSO notification, response, reporting, and impact mitigation GWDR Requirement The collection system agency shall develop and implement an overflow emergency response plan that identifies measures to protect public health and the environment. At a minimum, this 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 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 Waste Discharge Requirements or National Pollutant Discharge Elimination System (NPDES) permit requirements. The Sewer System Management Plan 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 untreated wastewater and prevent discharge of untreated wastewater to waters of the United States and minimize or correct any adverse impact on the environment resulting from the SSOs, including such accelerated or additional monitoring as may be necessary to determine the nature and impact of the discharge. City of Berkeley Page 6-1

42 6.3. Goals The City s goals with respect to responding to SSOs are: Respond quickly to minimize the volume of the SSO; Eliminate the cause of the SSO; Contain the spilled wastewater to the extent feasible; Minimize public contact with the spilled wastewater; Mitigate the impact of the SSO; and Meet the regulatory reporting requirements SSO Detection The processes that are employed to notify the City of the occurrence of an SSO include observation by the public, receipt of an alarm, or observation by City staff during the normal course of their work Public Observation Public observation is the most common way that the City is notified of blockages and spills. Contact information for reporting sewer spills and backups is in the phone book and on the City s website: The City s telephone number for reporting sewer problems is (510) The City is in the process of adding the reporting sewer spills and backups to its system Normal Work Hours The City s regular working hours are Monday through Friday from 7:30 a.m. to 5:00 p.m., except holidays. When a report of a sewer spill or backup is made during normal work hours, the Public Works Customer Service Call Center receives the call, takes the information from the caller, and communicates it to the field crew. The information regarding the service call is documented in a log book After Hours Service calls are forwarded to the Answering Service who receives the call, takes the information from the caller, and communicates it to the City s Swing Shift (until 9:30 p.m.) or the Public Works Standby Crew. The Answering Service confirms receipt of the service call with the pertinent information received from the caller in a daily log that is sent to Public Works Customer Service City Staff Observation City staff conducts periodic inspections of its sewer system facilities as part of their routine activities. Any problems noted with the sewer system facilities are reported to appropriate City staff who, in turn, respond to emergency situations. Work orders are issued to correct non-emergency conditions. City of Berkeley Page 6-2

43 Alarms Pump station alarms are transmitted via autodialer to the City s Emergency Communication Center. The information is communicated to field crews or standby personnel for response as described above SSO Response Procedures Sewer service calls are considered high priority events that demand a prompt response. The notification and response procedure flow chart is shown in Figure First Responder Priorities The first responder s priorities are: To follow safe work practices. To respond promptly with the appropriate equipment. To contain the spill wherever feasible. To restore the flow as soon as practicable. To minimize public access to and/or contact with the spilled sewage. To promptly notify the Public Works Senior Supervisor or Public Works Supervisor (working hours) or the On Call Supervisor (after hours) in event of major SSO. To return the spilled sewage to the sewer system. To restore the area to its original condition (or as close as possible) Safety The first responder is responsible for following safety procedures at all times. Special safety precautions must be observed when performing sewer work. There may be times when City personnel responding to a sewer system event are not familiar with potential safety hazards peculiar to sewer work. In such cases it is appropriate to take the time to discuss safety issues, consider the order of work, and check safety equipment before starting the job. City of Berkeley Page 6-3

44 Figure 6-1: Notification and Response Procedure Flow Chart City of Berkeley Page 6-4

45 Initial Response The first responder must respond to the reporting party/problem site and visually check for potential sewer stoppages or overflows. The first responder should: Note arrival time at site using Sewer Field Crew Report form. A sample report is included as Appendix 6-A. Verify the existence of a sewer system spill or backup. Identify and assess the affected area and extent of spill. Contact caller if time permits. Notify the Public Works Senior Supervisor or Public Works Supervisor (working hours) or the On-Call Supervisor (after hours) o If the spill appears to be large, flowing to a storm drain, in a sensitive area, or there is doubt regarding the extent, impact, or how to proceed. o If additional help is needed. If the spill is large or in a sensitive area, document conditions upon arrival with photographs. Decide whether to proceed with clearing the blockage to restore the flow or to initiate containment measures. The guidance for this decision is: o Small spills proceed with clearing the blockage. o Moderate or large spill where containment is anticipated to be simple proceed with the containment measures. o Moderate or large spills where containment is anticipated to be difficult proceed with clearing the blockage; however, call for additional assistance after 15 minutes without clearing the blockage and implement containment measures Restore Flow Using the appropriate cleaning equipment, set up downstream of the blockage and hydro clean upstream from a clear manhole. Attempt to remove the blockage from the system and observe the flows to ensure that the blockage does not recur downstream. If the blockage cannot be cleared within a reasonable time (15 minutes), or the sewer requires construction repairs to restore flow, then initiate containment and/or bypass pumping. If assistance is required, immediately contact other employees, contractors, and equipment suppliers Initiate Spill Containment Measures The first responder should attempt to contain as much of the spilled sewage as possible using the following steps: Determine the immediate destination of the overflowing sewage. Plug storm drains using air plugs, sandbags, and/or plastic mats to contain the spill, whenever appropriate. If spilled sewage has made contact with the storm drainage system, attempt to contain the spilled sewage by plugging downstream storm drainage facilities. City of Berkeley Page 6-5

46 Contain/direct the spilled sewage using dike/dam or sandbags. Pump around the blockage/pipe failure/pump station Water Quality Sampling and Testing Water quality sampling and testing is required whenever 1,000 gallons or more of spilled sewage enters a water body to determine the extent and impact of the SSO. The water quality sampling procedures are: The first responder should notify the City Environmental Health Division to collect samples. Samples should be collected as soon as possible after the discovery of the SSO event. The water quality samples should be collected from upstream of the spill, from the spill area, and downstream of the spill in flowing water (e.g. creeks). The water quality samples should be collected near the point of entry of the spilled sewage and every 100 feet along the shore for stationary water bodies. The City Environmental Health Division will analyze the results to determine the nature and impact of the discharge. Additional samples will be taken to determine when posting of warning signs can be discontinued. The basic analyses should include total coliform, fecal coliform, biochemical oxygen demand (BOD), dissolved oxygen, and ammonia nitrogen Recovery and Clean-Up The recovery and clean-up phase begins when the flow has been restored and the spilled sewage has been contained to the extent possible. The SSO recovery and clean-up procedures are: Estimate the Volume of Spilled Sewage Use the methods outlined in Appendix 6-E to estimate the volume of the spilled sewage. Wherever possible, document the estimate using photos of the SSO site before and during the recovery operation Recovery of Spilled Sewage Vacuum up and/or pump the spilled sewage and discharge it back into the sanitary sewer system Clean-up and Disinfection Clean-up and disinfection procedures should be implemented to reduce the potential for human health issues and adverse environmental impacts that are associated with an SSO event. The procedures described are for dry weather conditions and should be modified as required for wet weather conditions. Where clean-up is beyond the capabilities of City staff, a clean-up contractor will be used Private Property The City will follow the protocol outlined in Appendix 6-B. The incident will be documented using the Private Property Incident Form included as Appendix 6-C. City of Berkeley Page 6-6

47 Hard Surface Areas Collect all signs of sewage solids and sewage-related material either by hand or with the use of rakes and brooms. Wash down the affected area with clean water until the water runs clear. Take reasonable steps to contain and vacuum up the wastewater. Disinfect all areas that were contaminated from the overflow using disinfectant solution. Apply minimal amounts of the disinfectant solution using a hand sprayer. Document the volume and application method of disinfectant that was employed. Allow area to dry. Repeat the process if additional cleaning is required Landscaped and Unimproved Natural Vegetation Collect all signs of sewage solids and sewage-related material either by hand or with the use of rakes and brooms. Wash down the affected area with clean water until the water runs clear. The flushing volume should be approximately three times the estimated volume of the spill. Either contain or vacuum up the wash water so that none is released. Allow the area to dry. Repeat the process if additional cleaning is required Natural Waterways The Department of Fish and Game should be notified in the event an SSO impacts any riparian habitat. Fish and Game will provide the professional guidance needed to effectively clean-up spills that occur in these sensitive environments. Clean-up should proceed quickly in order to minimize negative impact. Any water that is used in the clean up should be de-chlorinated prior to use Wet Weather Modifications Omit flushing and sampling during heavy storm events with heavy runoff where flushing is not required and sampling would not provide meaningful results Public Notification Post signs and place barricades to keep vehicles and pedestrians away from contact with spilled sewage. Do not remove the signs until directed by the City Environmental Health Division. A sample warning sign is included as Appendix 6-G. Creeks, streams and beaches that have been contaminated as a result of an SSO should be posted at visible access locations until the risk of contamination has subsided to acceptable background levels. The warning signs, once posted, should be checked every day to ensure that they are still in place. In the event that an overflow occurs at night, the location should be inspected first thing the following day. The field crew should look for any signs of sewage solids and sewage-related material that may warrant additional clean up activities. Major spills may warrant broader public notice. The City Manager will authorize contact with local media when significant areas may have been contaminated by sewage. City of Berkeley Page 6-7

48 6.9. Failure Analysis Investigation The objective of the failure analysis investigation is to determine the root cause of the SSO and to identify corrective action(s) needed that will reduce or eliminate future potential for the SSO to recur. The investigation should include reviewing all relevant data to determine appropriate corrective action(s) for the line segment. The investigation should include: Reviewing and completing the Sewer Field Crew Report form, Reviewing past maintenance records, Reviewing available photographs, Conducting a CCTV inspection to determine the condition of the line segment immediately following the SSO and reviewing the video and logs, and Interviewing staff that responded to the spill. The product of the failure analysis investigation should be the determination of the root cause and the identification of corrective actions. The Collection System Failure Analysis Form (Appendix 6-D) should be used to document the investigation SSO Categories The California State Water Resources Control Board (SWRCB) has established guidelines for classifying and reporting SSOs. Reporting and documentation requirements vary based on the type of SSO. There are three categories of SSOs as defined by the SWRCB 1 : Category 1 - All discharges of sewage resulting from a failure in the City s sanitary sewer system (mains and lower laterals) that: A. Equal or exceed 1,000 gallons, or B. Result in a discharge to a drainage channel and/or surface water; or C. Discharge to a storm drainpipe that was not fully captured and returned to the sanitary sewer system. Category 2 - All other discharges of sewage resulting from a failure in the City s sanitary sewer system (mains and lower laterals). Private Lateral Sewage Discharges - Sewage discharges that are caused by blockages or other problems within a privately owned lateral SSO Documentation and Reporting All SSOs should be thoroughly investigated and documented for use in managing the sewer system and meeting established notification and reporting requirements. The procedures for investigating and documenting SSOs are: 1 State Water Resources Control Board Monitoring and Reporting Program No DWQ (as revised by Order No. WQ EXEC) Statewide General Waste Discharge Requirements for Sanitary Sewer Systems, California State Water Resources Control Board, February 20. City of Berkeley Page 6-8

49 Internal SSO Reporting Procedures Category II SSOs The field crew will fill out the Sewer Field Crew Report form and turn it in to the Public Works Senior Supervisor or the Public Works Supervisor. The Public Works Senior Supervisor or Public Works Supervisor will forward the report to the Public Works Maintenance Superintendent Category I SSOs The field crew will immediately notify the Public Works Senior Supervisor or Public Works Supervisor (working hours) or the On Call Supervisor (after hours). The Supervisor will notify the Public Works Maintenance Superintendent or the Deputy Director of Public Works. The field crew will fill out the Sewer Field Crew Report form and turn it in to the Public Works Senior Supervisor or Public Works Supervisor. The Public Works Senior Supervisor or Public Works Supervisor will forward the report to the Public Works Maintenance Superintendent. The Public Works Senior Supervisor or Public Works Supervisor (working hours) or the On Call Supervisor (after hours) will meet with field crew(s) at the site of the SSO event to assess the situation and to document the conditions with photos. In the event of a very large overflow or an overflow in a sensitive area, the Deputy Public Works Director or the Public Works Director will notify the City Manager. The City Manager may notify the City Council External SSO Reporting Procedures 2 The California Integrated Water Quality System (CIWQS) electronic reporting system should be used for reporting SSO information to the SWRCB whenever possible. A flow chart is included as Figure 6-2 showing the external reporting response requirements based on the type of SSO Category 1 SSOs that reach Waters of the State If a Category I SSO results in a discharge to waters of the State (a drainage channel or a surface water, if not fully recovered), the following reporting requirements apply: Within two hours of notification of the spill event the Public Works Senior Supervisor or Public Works Supervisor will: o Prepare an initial electronic report using RWQCB Electronic Reporting System, o Notify OES (and obtain spill number for use in other reports), and o Notify the City Environmental Health Division Within 24 hours of notification of the spill event, the Public Works Maintenance Superintendent or his/her designee will certify to the RWQCB that OES and the City Environmental Health Division were notified within two hours. This notification should be made using the RWQCB Electronic Reporting System. 2 Ibid. City of Berkeley Page 6-9

60 Appendix 6-E: Methods for Estimating Spill Volume A variety of approaches exist for estimating the volume of a sanitary sewer spill. This appendix documents the three methods that are most often employed. The person preparing the estimate should use the method most appropriate to the sewer overflow in question and use the best information available. Method 1 Eyeball Estimate The volume of small spills can be estimated using an eyeball estimate. To use this method imagine the amount of water that would spill from a bucket or a barrel. A bucket contains 5 gallons and a barrel contains 50 gallons. If the spill is larger than 50 gallons, try to break the standing water into barrels and then multiply by 50 gallons. This method is useful for contained spills up to approximately 200 gallons. Method 2 Measured Volume The volume of most small spills that have been contained can be estimated using this method. The shape, dimensions, and the depth of the contained wastewater are needed. The shape and dimensions are used to calculate the area of the spills and the depth is used to calculate the volume. Common Shapes and Dimensions RECTANGLE CIRCLE TRIANGLE W I D T H DIAMETER H E I G H T LENGTH BASE Step 1 Step 2 Step 3 Step 4 Step 5 Step 6 Step 7 Sketch the shape of the contained sewage (see figure above). Measure or pace off the dimensions. Measure the depth at several locations and select an average. Convert the dimensions, including depth, to feet. Calculate the area in square feet using the following formulas: Rectangle: Area = length (feet) x width (feet) Circle: Area = diameter (feet) x diameter (feet) x 0.79 Triangle: Area = base (feet) x height (feet) x 0.5 Multiply the area (square feet) times the depth (in feet) to obtain the volume in cubic feet. Multiply the volume in cubic feet by 7.5 to convert it to gallons City of Berkeley Page 6-20

61 Method 3 Duration and Flowrate Calculating the volume of larger spills, 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 spill and the flowrate. The methods of estimating duration and flowrate are: Duration: The duration is the elapsed time from the time the spill started to the time that the flow was restored. Start time: The start time is sometimes difficult to establish. Here are some approaches: Local residents can be used to establish start time. Inquire as to their observations. Spills that occur in rights-of-way are usually observed and reported promptly. Spills that occur out of the public view can go on longer. Sometimes observations like odors or sounds (e.g. water running in a normally dry creek bed) can be used to estimate the start time. Changes in flow on a downstream flowmeter can be used to establish the start time. Typically the daily flow peaks are cut off or flattened by the loss of flow. This can be identified by comparing hourly flow data during the spill event with flow data from prior days. Conditions at the spill site change over time. Initially there will be limited deposits of toilet paper and other sewage solids. After a few days to a week, the sewage solids form a lightcolored residue. After a few weeks to a month, the sewage solids turn dark. The quantity of toilet paper and other materials of sewage origin increase over time. These observations can be used to estimate the start time in the absence of other information. Taking photographs to document the observations can be helpful if questions arise later in the process. It is important to remember that spills may not be continuous. Blockages are not usually complete (some flow continues). In this case the spill would occur during the peak flow periods (typically 10:00 to 12:00 and 13:00 to 16:00 each day). Spills that occur due to peak flows in excess of capacity will occur only during, and for a short period after, heavy rainfall. End time: The end time is usually much easier to establish. Field crews on-site observe the blow down that occurs when the blockage has been removed. The blow down can also be observed in downstream flowmeters. Flow Rate: The flowrate is the average flow that left the sewer system during the time of the spill. There are three common ways to estimate the flowrate: The San Diego Manhole Flowrate Chart: This chart, included as Appendix 6-F, shows sewage flowing from manhole covers at a variety of flowrates. The observations of the field crew can be used to select the appropriate flowrate from the chart. If possible, photographs are useful in documenting basis for the flowrate estimate. Flowmeter: Changes in flows in downstream flowmeters can be used to estimate the flowrate during the spill. Counting Connections: Once the location of the spill is known, the number of upstream connections can be determined from the sewer maps. Multiply the number of connections by 200 to 250 gallons per day per connection or 8 to 10 gallons per hour per connection. City of Berkeley Page 6-21

62 For example: 22 upstream connections x 9 gallons per hour per connection = 198 gallons per hour / 60 minutes per hour = 3.3 gallons per minute Spill Volume: Once duration and flowrate have been estimated, the volume of the spill is the product of the duration in hours or days and the flowrate in gallons per hour or gallons per day. For example: Spill start time = 11:00 Spill end time = 14:00 Spill duration = 3 hours 3.3 gallons per minute x 3 hours x 60 minutes per hour = 594 gallons City of Berkeley Page 6-22

65 Section 7. FOG Control Program 7.1. Introduction This section presents the City s Fats, Oils, and Grease (FOG) Control Program. This FOG Control Program will be managed, staffed, and administered by the East Bay Municipal Utility District (EBMUD). The City Environmental Health Division will assist EBMUD in investigating problem areas Regulatory Requirements for FOG Control Element of SSMP The summarized requirements for the FOG Control element of the SSMP are: RWQCB Requirement The collection system agency must evaluate its service area to determine whether a FOG control program is needed. If so, a FOG control program shall be developed as part of the SSMP. If the collection system agency determines that a FOG program is unnecessary, proper justification must be provided GWDR Requirement The collection system agency shall evaluate its service area to determine whether a FOG control program is needed. If the collection system agency determines that a FOG program is not needed, the collection system agency must provide justification for why it is not needed. If FOG is found to be a problem, the collection system agency must prepare and implement a FOG source control program to reduce the amount of these substances discharged to the sanitary sewer system. The FOG source 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 grease removal devices, maintenance requirements, BMP requirements, record keeping and reporting requirements; (e) Authority to inspect grease producing facilities, enforcement authorities, and determination of whether the Agency has sufficient staff to inspect and enforce the FOG ordinance; (f) An identification of sewer system sections subject to FOG blockages and the 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 sewer system, for each sewer system section identified in (f) above. City of Berkeley Page 7-1

66 7.3. Nature and Extent of FOG Problem Data regarding the nature and extent of the FOG problems in City s sewer system was analyzed. The City reported 13 SSOs associated with public sewer mains during CY Three of the SSOs (23% of the total) were caused by grease: one SSO was located in a commercial area, one was located in a high-density residential area, and one was located in a residential area. The locations of FOG-related SSOs are shown in Figure 7-1. The City s preventive maintenance efforts combined with the EBMUD FOG Source Control Program appear to be effective in minimizing the problems associated with commercial FOG sources. Figure 7-1: Locations of FOG-Related SSOs City of Berkeley Page 7-2

67 7.4. FOG Source Control Program The City will continue to contract with EBMUD for FOG Source Control Program services. The EBMUD Regional FOG Control Program is described in Appendix 7-A. The City Environmental Health Division has a Commercial Food Facility Inspection Program that inspects restaurants and other food service establishments within the City. The inspections for sanitation compliance include checking the food handling facilities practices and storm water inspections, as well as for wastewater discharge in order to control FOG in identified hot spots. The City Environmental Health Division will assist EBMUD in the investigation of problem restaurants and other food service establishments Public Outreach Program City crews provide information on proper FOG disposal to residents that have experienced a FOG-related blockage or SSO. EBMUD will prepare materials to be used as the basis for a focused public education/outreach program. EBMUD and the City will provide the public education/outreach materials to commercial and residential sources that are tributary to sewers that experience FOG-related stoppages and SSOs Acceptable FOG Disposal Facilities A list of grease haulers approved by EBMUD is included as Appendix 7-B. There is adequate disposal capacity for FOG from commercial sources within the City s service area FOG Preventative Maintenance The City s preventive maintenance program is focused on the problematic sewer line segments. The results of the sewer cleaning operations will be used to revise sewer cleaning frequencies. The City staff will provide the EBMUD FOG Source Control Program staff with timely notice when gravity sewers experience FOG-related blockages or SSOs. City of Berkeley Page 7-3

Introduction This section of the SSMP presents the City s programs and activities to provide adequate system capacity and thereby prevent system overflows Regulatory Requirements for the System Evaluation and Capacity Assurance Plan Element of SSMP The summarized requirements for the System Evaluation and Capacity Assurance Plan (SECAP) element of the SSMP are: RWQCB Requirement 4 (a) Each wastewater collection system agency shall establish a process to assess the current and future capacity requirements for the collection system facilities. (b) Each wastewater collection system agency shall prepare and implement a capital improvement plan to provide hydraulic capacity of key sewer system elements under peak flow conditions GWDR Requirement 5 The Enrollee shall 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 of the capacity of key system components, hydraulic deficiencies (including components of the system with limiting capacity) and the major sources that contribute to the peak flows associated with overflow events. (b) Design Criteria: Where design criteria do not exist or are deficient, undertake the evaluation identified in (a) above to establish appropriate design criteria. (c) Capacity Enhancement Measures: The steps needed to establish a short-term and long-term capital improvement plan to address identified hydraulic deficiencies, including prioritization, alternatives analysis, and schedules. The capital improvement plan may include increases in pipe size, inflow and infiltration (I/I) reduction programs, increases and 4 Sewer System Management Plan (SSMP) Development Guide, San Francisco Bay Regional Water Quality Control Board in cooperation with Bay Area Clean Water Agencies, July State Water Resources Control Board Order No Statewide General Waste Discharge Requirements for Sanitary Sewer Systems, California State Water Resources Control Board, May 2, City of Berkeley Page 8-1

The City will update the data and analysis of performance measures at the time of the evaluation. The City may use other performance measures in its evaluation. The City will prioritize its actions and initiate changes to this SSMP and the related programs based on the results of the evaluation. City of Berkeley Page 9-2

75 Figure 9-1: Trend in SSO Events by Asset Type 9.6. SSMP Updates The City will update its SSMP at least every five years. The first update will be completed on or before August 31, The City will determine the need to update its SSMP more frequently based on the results of the annual audit and the performance of its sanitary sewer system using information from the Monitoring and Measurement Program. In the event that the City decides that an update is warranted, the process to complete the update will be identified at that time. The City will complete the update within one year following identification of the need for the update. The City staff will seek the approval from the City Council for any significant changes to the SSMP. The authority for approval of minor changes such as employee names, contact information, or limited procedural changes is delegated to the Director of Public Works. City of Berkeley Page 9-3

77 Section 10. SSMP Program Audits Introduction This section of the SSMP presents the process that the City will follow to audit its SSMP program Regulatory Requirements for the SSMP Program Audits Element of SSMP The summarized regulatory requirements for the SSMP are: RWQCB Requirement Each wastewater collection system agency shall conduct an annual audit of their SSMP which includes any deficiencies and steps to correct them (if applicable), appropriate to the size of the system and the number of overflows, and submit a report of such audit along with their annual report by March 15 th of the following year GWDR Requirement As part of the SSMP, the Enrollee shall conduct periodic internal audits, appropriate to the size of the system and the number of SSOs. At a minimum, these audits must occur every two years and a report must be prepared and kept on file. This audit shall focus on evaluating the effectiveness of the SSMP and the Enrollee s compliance with the SSMP requirements, including identification of any deficiencies in the SSMP and steps to correct them SSMP Audits The Environmental Protection Agency (EPA) and the RWQCB conducted an inspection of the City s sanitary sewer system programs and activities. The questionnaire that the City completed in response to EPA s request for information is included as Appendix 10-A. The questionnaire is intended to provide information for use in future audits. The City will audit its SSMP every year. The audit will determine whether the SSMP meets the current requirements of the GWDR, whether the SSMP reflects the City s current practices, and whether the City is following the SSMP. The first audit will be completed by March 1, 2010 and will cover CY The audit will be conducted by a team consisting of City Public Works Department staff. The audit team may also include members from other areas of the City, outside agencies, and/or contractors. The scope of the audit will cover each of the sections of the SSMP. The SSMP Audit Checklist, based on the requirements in the GWDR, will be used for the audit (included as Appendix 10-A). The results of the audit will be included in an SSMP Audit Report. The SSMP Audit Report will focus on the effectiveness of the SSMP program, compliance with the GWDR requirements, and identification of any deficiencies in the SSMP. The SSMP Audit Report will identify revisions that may be needed for a more effective program. Information collected as part of Section 9 of the SSMP, Monitoring, Measurement, and Program Modifications, will be used in preparing the audit. City of Berkeley Page 10-1

78 Tables and figures or charts will be used to summarize information about these indicators. The Audit Report will be submitted to the RWQCB, along with the Annual Report of SSOs, by March 15 th of each year. Copies of the annual Audit Reports will be maintained by the City for five years.

107 Section 11. Communication Program Introduction This section of the SSMP outlines the process involved in communicating with interested members of the public regarding the development, implementation, and performance of this plan. This Communication Program also addresses communication between Berkeley and its satellite sewer systems Regulatory Requirements for the Communications Program Element of SSMP The requirements for the Communication Program section of the SSMP are: RWQCB Requirement The RWQCB does not require a Communication Program GWDR Requirement The City shall: (a) Communicate on a regular basis with the public on the development, implementation, and performance of its SSMP. The communication system shall provide the public the opportunity to provide input to the Enrollee as the program is developed and implemented. (b) Create a plan of communication with systems that are tributary and/or satellite to the Enrollee s sanitary sewer system Communication during SSMP Development and Implementation The City posted a notice on its website and with the official notices on the Bulletin Board at City Hall to inform interested members of the public it was developing an SSMP. The notice was: The City of Berkeley is updating its Sewer System Management Plan (SSMP) to meet the requirements established by the State Water Resources Control Board Order , Statewide General Discharge Requirements of Sanitary Sewer Systems. The goal of the SSMP is to minimize the frequency and severity of sanitary sewer overflows. The SSMP will cover the management, planning, design, operation and maintenance of the City s sanitary sewer system.
