3 Introduction A. Sewer System Management Plan This Sewer System Management Plan (SSMP) has been prepared by the Monterey Regional Water Pollution Control Agency (MRWPCA). It is a summary of the policies, procedures, and activities that are included in the planning, management, operation, and maintenance of the MRWPCA sanitary sewer system. This SSMP is intended to meet the requirements of the State Water Resources Control Board. The structure (section numbering and nomenclature) of this SSMP follows the General Waste Discharge Requirements for Wastewater Collection Agencies (GWDR), State Water Resources Control Board Order Number dated May 2, B. Sanitary Sewer System Facilities The MRWPCA owns and operates a sanitary sewer system that serves a population of approximately 250,000 people in 11 member entity jurisdictions. These jurisdictions include City of Del Rey Oaks, City of Monterey, City of Pacific Grove, City of Salinas, City of Sand City, City of Seaside, Castroville Community Services District, Marina Coast Water District, Moss Landing County Sanitation District, Boronda County Sanitation District and Monterey County. The sewer system consists of trunk line transportation services for each of the of 11 member entities via a system of 10 Agency-owned pump stations and 34 miles of pipeline. Each MRWPCA member entity owns, operates, and maintains their own sewerage collection system of smaller gravity mains and operates under an entity-specific SSMP as specified in the GWDR. MRWPCA's system is subdivided into four pipeline systems: Monterey Peninsula Interceptor System (Pacific Grove Monterey Seaside - Fort Ord and Marina), which represents 46 percent of the total flow to the regional treatment plant (RTP). Salinas Interceptor System (Salinas to the treatment plant) --This represents 51 percent of the total flow to the treatment plant. Castroville Interceptor System (Moss Landing-Castroville) This represents 3 percent of the total flow to the treatment plant. Outfall System (Treatment plant to the deep-water ocean outfall)-this conveys all the treated effluent from the treatment plant not processed thorough the tertiary plant and distribution system. Each trunk line consists of a single pipeline with no parallel or looped lines. The pipelines range in size from 6 to 60 inches in diameter and are between 20 and 28

4 years old. The lines include ductile iron and both lined and unlined concrete pipe. Most of the lines are force mains. Operating pressures range from several hundred feet of head on the discharge side of large pump station to un-pressurized gravity flows, depending on system hydraulics. C.

8 Section I: Goals A. Introduction This SSMP section identifies goals MRWPCA has set for the management, operation and maintenance of the sewer system. These goals are the defining targets at which the more specific objectives of the SSMP are aimed. These goals also assist Agency staff in providing the best quality work and putting into practice improvements in management related to the wastewater conveyance system. B. Regulatory Requirements for Goals Section The summarized requirements for the Goals section of the SSMP are: GWDR Requirement The collection system agency must develop goals to properly manage, operate, and maintain all parts of its wastewater collection system in order to reduce and prevent SSOs, as well as to mitigate any SSOs that occur. C. SSMP Goals The SSMP is a critical component to satisfying the Agency s mission statement: The Monterey Regional Water Pollution Control Agency is dedicated to meeting the wastewater and reclamation needs of our member agencies while protecting the environment. In support of this mission, the MRWPCA has developed and implemented the following goals for the management, operations and maintenance of the Agency wastewater conveyance system. Minimize the number and impact of sanitary sewer overflows (SSOs) that occur; Maintain or improve the condition of the collection/conveyance system infrastructure in order to provide reliable service and adequate capacities now and into the future; Properly manage, operate, and maintain the wastewater collection system; Prevent public health hazards; Prevent unnecessary damage to public and private property; Perform all management, operations and maintenance in a safe manner to avoid personal injury and property damage; Maintain design construction standards and specifications for the installation of new wastewater systems; Verify the wastewater collection system has adequate capacity to convey sewage during peak flows;

9 Respond to sanitary sewer overflows quickly and mitigate the impact of the overflow; Provide training on a regular basis for staff in collection maintenance and operations; Encourage and support participation in the California Water Environment Associations voluntary Wastewater Certification Program and on-going training programs; Assist Member Entities with Fats, Oil, and Grease (FOG) program maintenance. These programs limit fats, oils, grease, and other debris that may cause blockages in their sewage collection systems; Identify and prioritize structural deficiencies and implement short-term and long-term maintenance and rehabilitation actions to address each deficiency; Meet all applicable regulatory notification and reporting requirements; Provide excellent customer service; and Assist member entities in meeting these goals as well as the goals of their individual SSMPs. This SSMP supports the MRWPCA s existing operations and maintenance program by providing guidelines and procedures for management of the Agency wastewater conveyance system. The SSMP will support the Agency in reducing the frequency and impacts of SSOs by providing guidance for appropriate maintenance, capacity management, and emergency response.

10 Section II: Organization A. Introduction This section of the SSMP identifies MRWPCA staff responsible for maintaining and implementing this SSMP, responding to SSO events (both Agency SSOs and member entity SSOs), and meeting the SSO reporting requirements. This section also identifies the Authorized Representative or Legally Responsible Officer for completing and certifying all SWRCB required spill reports. B. Regulatory Requirements for Organization Section The summarized requirements for the Organization section of the SSMP are: GWDR Requirement The collection system agency s SSMP must identify: (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 in the SSMP program.

58 Section IV: Operations and Maintenance Program A. Introduction This section of the Sewer System Management Plan (SSMP) is intended to provide an overview of the Agency s sewer system operations and maintenance program. B. Regulatory Requirements for the Operations and Maintenance Program Section The requirements for the Operations and Maintenance Program section of the SSMP are: GWDR Requirement (Operations and Maintenance): The GWDR requirements for the Operations and Maintenance Program are: (a) Maintain an up-to-date map of the sanitary sewer system, showing all gravity line segments and manholes, pumping facilities, pressure pipes and valves, and applicable storm water conveyance facilities; (b) Describe routine preventive operation and maintenance activities by staff and contractors, including a system for scheduling regular maintenance and cleaning of the sanitary sewer system with more frequent cleaning and maintenance targeted at known problem areas. The Preventative Maintenance (PM) program should have a system to document scheduled and conducted activities, such as work orders; (c) Develop 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; (d) Provide training on a regular basis for staff in sanitary sewer system operations and maintenance, and require contractors to be appropriately trained; and (e) Provide equipment and replacement part inventories, including identification of critical replacement parts. C. Operations and Maintenance Program The following presents the portions of the Operations and Maintenance Program that respond to the SWRCB requirements.

59 1. System Overview Each MRWPCA entity owns, operates and maintains their own sewage collection systems and operates under their own Collection System WDR. The sewage within the Agency area is conveyed to regional pump stations owned and operated by MRWPCA. These stations then pump the sewage to the regional treatment plant north of the City of Marina. MRWPCA provides "trunk line" transportation services via a system of 10 Agency-owned pump stations and 30 miles of pipeline. MRWPCA also operates under contract 18 pump stations owned by some of its member entities. MRWPCA's system is subdivided into four pipeline systems: Monterey Peninsula Interceptor System (Pacific Grove Monterey Seaside Fort Ord and Marina) represents 46 percent of the total flow to the treatment plant. Salinas Interceptor System (Salinas to the treatment plant) -This represents 51 percent of the total flow to the treatment plant. Castroville Interceptor System (Moss Landing Castroville) This represents 3 percent of the total flow to the treatment plant. Outfall System (Treatment plant to the deep-water outfall) This conveys all the treated effluent from the treatment plant not processed thorough the tertiary plant and distribution Average dry weather flows are currently on the order of 21 mgd. Peak wet weather flows in winter months are often on the order of 40 mgd. Pipelines As noted above, MRWPCA owns and operates approximately 30 miles of force main/gravity pipelines comprising three "trunk line" interceptor systems. Each trunk line consists of a single pipeline with no parallel or looped lines. The pipelines range in size from 6 to 60 inches in diameter and are between 20 and 28 years old. The lines include ductile iron and both lined and unlined concrete pipe. Most of the lines are force mains, and flowing full so the force mains cannot be readily internally inspected. Operating pressures range from several hundred feet of head on the discharge side of large pump station to un-pressurized gravity flows depending on system hydraulics. Table 4.1 represents a simple schedule that shows the size of pipe, and its function.

Map corrections are noted by field crews and submitted to the Engineering Supervisor. Maps are updated as appropriate. 2. Preventive and Routine Operation and Maintenance MRWPCA maintains 28 pump stations. Ten stations are owned by MRWPCA. The other eighteen stations are owned by member entities that contract with MRWPCA for maintenance. The pump stations have a Lead Mechanic in charge of preventive maintenance and usually operate with a crew of between two and four mechanics depending on work load. This work force maintains all of the stations and the transmission lines. The crews perform routine preventative maintenance, predictive maintenance, repair, and installation of equipment. Each of the stations MRWPCA owns are checked 2 to 3 times a week. The smaller City stations are checked weekly. The monitoring frequency is dependent on the size, location, volume of flow and type of alarm system installed. Each station has inspection sheets that cover daily, weekly, and monthly checks. All repair work and preventive maintenance checks are managed through the Agency s computer management system. Repair work orders are routed through the Agency Planner who ensures the necessary parts are ordered and the repair is then scheduled. In the event of work that cannot wait for scheduling, the maintenance department has a Senior Mechanic who is

62 assigned all HOT work for the day and is responsible to respond. The Agency also has four electricians. The majority of the stations have built in Emergency Generators that start automatically during a power outage. These Generators are on a weekly and Monthly Preventative Maintenance Schedule, maintained by the Agency Planner using a CMMS program. Additionally MRWPCA has two portable Generators for use at the stations with no stationary emergency power. These portable generators are also on the preventative maintenance schedule along with all emergency response equipment. 3. Rehabilitation and Replacement Program The Agency has no typical collection systems per say and does not have a programmed inspection system for force mains. MRWPCA has in the past inspected small portions of the force mains by shutting down small parts of the system but this method is both dangerous and cost prohibitive. The Agency has now adopted a preventative maintenance program of checking all above ground facilities such as air relief valves on a quarterly basis and checking manholes on an annual basis to visually inspect the lines where possible. The Agency pipelines are either completely submerged or are lined, substantially reducing the risk of a pipe failure. The Agency has a number of funds that are used to replace equipment and maintain the Agency facilities. These include a Equipment Replacement Fund with a approximately $1.5 Million, a major Operations and Maintenance Fund that is used for unscheduled major repairs and General Fund where normal or routine repairs are budgeted. Each year the Agency s Five Year and Ten Year Capital Improvement Plan (CIP) is reviewed and projects are funded based on priorities throughout the agency. The average CIP budget is approximately $4.5 million per year. The current approved project plan is available on the Agency website at 4. Training MRWPCA uses a combination of in-house classes; on the job training; and conferences, seminars, and other training opportunities to train its staff. The Agency requires all maintenance employees to hold a CWEA Mechanical or Electrical certification. Additionally we have a number of employees with CWEA Collection Technology Certifications. However, since MRWPCA doesn t maintain typical collection systems, this certification has not been made a requirement. The Agency does give a one-time bonus for Agency personnel that become certified in this field. The Agency has an ongoing training program for its employees for their requirements to acquire continuing educational units for each certificate. Additionally the Agency provides a number of safety related courses throughout the year as well as a safety training program through CSRMA. Listed below are the Maintenance Departments member s certifications:

Equipment and Replacement Parts MRWPCA maintains a store room with a number of spare parts for all major pump stations along with a spare pump assembly for all major pump assemblies at the station. The Agency also contracts with a number of our member entities to maintain their pump and lift stations. In these cases it is cost prohibitive to stock all the different end items and repair parts so the Agency has established a method to pump around each of these stations with portable equipment until repairs parts can be obtained. The key to this strategy and what makes it a viable option to having to have a large volume of parts is that each pump station has a minimum of two pumps; each station the Agency operates is designed to pump peak wet weather flow with only one pump. So in order for the station to be incapable of meeting its flow demands it would be necessary for both pumps to fail. Agency Standard Operating Procedures are to establish a pump around contingency plan when any station is down to one pump, or in danger of not meeting pumping capacity. This policy allows for the ordering of any needed parts if not on hand. For normal expendable parts and materials such as oil, grease, filters, and fan belts needed to run auxiliary equipment a supply is either kept in the Agency store room or are obtainable from local venders. Additionally the agency has a Maintenance Planner who is responsible for establishing procedures to ensure that all vender lists are kept current and that the Agency s Computer Management Program is updated for each asset with the critical repair part numbers and suppliers. To accomplish this task the Agency has a dedicated store room clerk to assist the Planner. The clerk works in the store room updating inventories and ensuring necessary materials and spare parts are kept at assigned levels.

65 Section V: Design and Performance Provisions A. Introduction The Agency s design and construction standards are used by the Agency staff and are communicated to consulting engineers and/or contractors at the start of a design process or proposed development. B. Regulatory Requirements for the Design and Performance Provisions Section The regulatory requirements for the Design and Performance Provisions section are: GWDR Requirement (Design and Performance Provisions): (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. C. Design Criteria Since the Agency does not maintain a typical collections system, design criteria are evaluated on a case-by-case basis and utilize the most current California Building, Mechanical, Electrical, Plumbing and Fire Codes as well as industry standards. D. Construction Standards Since the Agency does not maintain a typical collections system construction standards are evaluated on a case-by-case basis and utilize the most current California Building, Mechanical, Electrical, Plumbing and Fire Codes as well as industry standards. The Agency employs the latest version of the Standard General Conditions of the Construction Contract prepared by the Engineers Joint Contract Documents Committee and issued and published jointly by the American Consulting Engineers Council, the National Society of Professional Engineers, and the American Society of Professional Engineers. The Agency also employs the latest version of the State of California Department of Transportation Standard Plans and Standard Specifications as appropriate to the specific project.

66 Section VI: Sanitary Sewer Overflow Emergency Response Plan A. Introduction The Agency has an aggressive Emergency Response plan that is centered around responding to the Agency s 10 pump stations and the 16 lift stations that the MRWPCA maintains for the Cities of Pacific Grove (7), Monterey (5) and Seaside Sanitation District (4). Two pump stations have numerous alarm systems that are monitored 24/7 at the MRWPCA s Regional Treatment Plant. Each station has a primary alarm system and a secondary back up system. During the normal work day the Agency Pump Station maintenance crews respond to alarms. During off hours the Agency maintains an On-call Mechanic and an On-call electrician to respond to any alarms after hours. Since the Agency has no typical collection system piping; only transmission piping (Force main/gravity mains) from the Agency pump stations to the RTP, the Agency maintains a number of emergency repair clamps. Additionally the Agency retains emergency contact numbers for local Construction companies that have the ability to conduct repairs on Agency lines if necessary. 1. Purpose The Sanitary Sewer Overflow Response Plan (SSORP) is designed to ensure that every report of a confirmed sanitary sewer overflow (SSO) is immediately dispatched to the appropriate crews. This plan provides a procedure that, when enacted in response to the sewer overflow/spill, reduces or eliminates public health hazards, prevents unnecessary property damage, and minimizes the inconvenience of service interruptions. This plan provides procedures for Agency staff to follow in responding to, cleaning up, and reporting SSOs. 2. Safety Whenever qualified Agency personnel respond to a report of an overflow/spill, they may encounter an emergency situation that requires immediate action. The most critical aspect of resolving an incident of this nature is to safely and competently perform the actions necessary to return the system or facility to normal operations as soon as possible. The most important item to remember during this type of incident is that safe operations always take precedence over expediency or shortcuts. Upon arrival at an SSO, the Field Maintenance Personnel will conduct a hazard assessment to determine potential safety hazards. There is always a possibility that a sewage overflow may contain unknown hazardous waste or chemicals. On rare occasions, gasoline and industrial solvents have been found in the sewer system. If a hazardous waste is suspected the responding field crew will notify the RTP operations staff immediately and will request the local Fire Department s Hazardous Materials Response Team. The Maintenance Manager and Compliance Engineer should be notified as soon as possible. Personnel shall stay clear of any hazards and secure the area from the public.

67 Depending on the nature or cause of the SSO, personnel may be required to remove a mainline blockage, repair a damaged section of pipeline, or wash/clean a City street. At this point, it is essential that all standard safety procedures and/or duties are followed as deemed appropriate. Typical responses may require personnel to implement the following types of safety procedures: Standard personal protective equipment; Lock-out/tag-out of equipment for repairs; Confined space entry procedures; Traffic control; Implementation of Stormwater BMP s; Heavy equipment operation; and/or Adequate communication via two-way radio and/or cellular telephone. B. Regulatory Requirements for SSORP Section The requirements for the SSORP section are: 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;

68 (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. C. Sanitary Sewer Overflow Response 1. Receipt of Information Regarding SSO MRWPCA Staff maintains an emergency procedure manual within the RTP control room which is manned 24 hours a day seven days a week. In the event of a SSO from one of the Agency facilities or a broken pipeline along the sewer transportation system and the notification form an outside source, the call will be routed to the RTP Control Room. The Control Room Operator will start the notification process along two paths. First, the operator will notify the on-call mechanic who will be the first responder to the alarm or incident. Second, once the Operator has the needed information, they will start the outside notifications beginning with OES within two hours of the reported incident. The reporting form has been provided in this section as Appendix VI-1 and was been updated in June The operator will then start notifying the required staff based on the direction of the on-scene responder. Depending on the size of the incident, the operator will call in additional control room help to manage the situation and continue reporting. The Agency s Emergency Operations Center Standing Operation Procedures outline the duties of those who may be called in as a result of an incident. The Control Room Operator should obtain all relevant information available regarding the overflow, including: Time and date call was received; Specific location; Description of problem; Time possible overflow was noticed by caller; Caller s name and phone number; Observations of the caller (e.g., odor, back or front of property); and Other relevant information that will enable the responding investigator and crews, if required, to quickly locate, assess, and stop the overflow. 2. Overall Detection of Spills and Leaks MRWPCA mans its Regional Treatment Plant 24 hours a day seven days a week. The Agency s ten pump stations and sixteen of the eighteen pump stations owned by the Member entities and operated by the Agency have redundant alarm systems. One system is a radio system the other is a phone system on either hard wire or a cellular phone. The other two stations are small enough that two alarm systems are not warranted. During the normal work day if an alarm is received in

69 the control room the Operator calls the Lead Mechanic in the field responsible for the maintenance of the pump stations to respond. If the alarm is received after hours or on weekends or holidays the control room operator calls the on-call mechanic and or electrician to respond to the alarm. Once the mechanic/electrician arrives at the station as the initial first responder they are responsible to correct the alarm or call out the necessary personnel to assist with the condition causing the alarm. If there is a failure in the piping system the detection would be from one of two sources; the public who visually sees the bypass or from alarms in the RTP control room that would show a loss of pressure in the header pressure of our bigger stations or potentially some other unusual alarm/flow pattern. If one of these conditions occurs then the same procedure for calling out agency personnel and notifications applies. 3. Responding to an SSO The Control Room Operator records the information and contacts the designated Field Maintenance Personnel. The response time is typically 15 to 30 minutes. A crew personnel list is updated on a daily basis. If an SSO occurs during non-business hours, the on-call Field Maintenance Staff is contacted. This person must respond within 45 minutes of receiving the information. As indicated above, the Agency always has an operator on duty at the RTP control room. To respond to alarms from the pump stations there is always a minimum of three employees; a mechanic, electrician and Generator mechanic on-call and available to respond to pump station alarms. Additionally the Maintenance Supervisor and Maintenance Manager are assigned agency vehicles so that they can respond as well if needed. The Agency has a response manual that lists the possible alarms from the stations and possible actions that can be taken for each alarm. Listed in Appendix VI-2 to this plan is a complete list of station information with current information on the particular pump station. The tables include by-pass locations and equipment needed for an emergency response if needed. To assist in the response the Agency also has a number of trucks and emergency equipment stationed throughout the Agency s service area of responsibility to speed the response if additional personnel are needed. The Agency has agreements in place with member entities to assist in the initial response if the problem is within a member entities pump station which MRWPCA is under contract to maintain. A guide to aid in determining SSO quantities is included as Appendix VI Responding Staff Responsibilities The Agency uses an On-scene Commander to determine the necessary recovery and clean-up steps. The recovery of an incident within the MRWPCA system will be one of two types. The first type is reacting to and repairing/pumping around a failed pump station due to electrical/mechanical or natural causes. If a pump station fails the On- Scene Commander will first take all possible actions to restore the pump station

70 to normal operations. If this is not possible the Agency has the necessary equipment to either pump around the stations and/or hook-up emergency electrical generators to run the station. The Agency has numerous repair parts that will facilitate a quick repair and recovery. In Appendix VI-2 to Section VI there is a general pump station information guide with a list of necessary emergency equipment necessary to pump around the stations. The pump station data sheets also list equipment, flow, and by-pass locations. The second type of recovery would be from a broken or ruptured transportation pipe. In this case the Agency has a number of Contractors that would be called to conduct the necessary repairs. MRWPCA also has a number of repair clamps for our smaller diameter pipes. Most pipeline repairs will be contracted out on an emergency basis and under the direction of one of the Agency s engineers with assistance from the Maintenance department. Recovery for this type incident will very from site to site. The Field Maintenance Personnel responding to a sewer backup has the immediate responsibility to protect people, property, and the environment from the effects of a sewage spill overflow. To meet these objectives in a rapid, effective, and organized manner, staff will respond and fulfill the duties in the following categories as directed by this plan. REDUCE or STOP the overflow at its source. CONTAIN spilling sewage from entering waterways. CAPTURE the sewage where it can be recovered and returned to the sewer system. CONTAIN sewage in advantageous locations (i.e., vacant lots, plugged storm system, curb/gutter, etc.) Containment materials include sand, sand bags, etc. CONTROL the spill area and bypass the area if necessary. BYPASS the obstructed line by pumping the spillage into another nonrestricted line or vacuum with a VacCon. CLEANUP the affected public areas to ensure public safety. (The Wastewater Supervisor must approve cleaning on private property.) WASH DOWN and CONTAIN run-off, being careful not to wash sewage into storm drainage system. D. SSO Response Procedures This section provides the step-by-step procedures explaining the actions to be taken in response to an SSO. A flow diagram of the SSO response process is included as Figure VI-1.

If required, Maintenance Manager will notify local regulatory agencies Document SSO, volume spilled, volume recovered, how volume was determined. Complete SSO Reporting Requirements

72 E. SSO Recovery and Cleanup Procedures This section provides guidelines and procedures for cleaning and disinfecting the area contaminated by a sanitary sewer overflow. 1. SSO on Public Property To minimize health affects to the public and to protect the environment: Start cleaning the wastewater spill area as soon as possible. Secure the affected area with cones, barricades, caution tape, etc. Take pictures to document the overflow. This is very important if the overflow causes property damage. Inspect the storm drain catch basins to determine whether wastewater has entered the storm system and to what extent. If necessary, install plugs, sandbags, sand/rock, etc. to contain the sewage. Flush the area with water and vacuum up all liquid and/or pump it back into the collection system. Remove all debris found in the spill area. If a disinfectant is used, it must be collected and deposited in the collection system. Thoroughly inspect the spill area before you leave. 2. SSOs that reach Surface Water If an SSO is confirmed to have entered a creek or waterway, determine the extent of the SSO: It must be determined if the creek is safe to enter. During the winter storm season, cleaning the creek may not be possible due to high water flows. Cleaning a creek can be very difficult. Get plenty of help; contact additional field maintenance crew members if necessary. If possible, block the creek downstream of the contaminated flow based on visual evidence. Block the creek in an area that is safe to enter and is accessible to pumps. Pump or vacuum contamination from creek and return it to collection system. As soon as possible, contact the Maintenance Manager who will notify required State agencies, post public SSO spill signs, and sample the creek. Follow-up sampling will also be required. F. Public Access and Warning During any incident MRWPCA deploys its Safety Officer to ensure that both the public and employees are protected and are performing their duties safely. The Safety Officer along with the On-Scene Commander will take all measures necessary to protect the public by limiting access to the incident site. This is done in cooperation with the local fire and police departments. MRWPCA has the necessary signage, cones and barriers to shut down or divert traffic around the affected pump station or pipeline. The Local Police

73 in our service area will assist with this task. Additionally the Public Works departments within the cities where we operate also assist in this task. The Control room maintains a current contact list of all Public Works, Fire and Police numbers necessary to seek help if necessary the Safety Officer or the On-scene Commander will make this call depending on the situation and necessity to block public access. Warnings are posted by both the Agency and the Monterey County Health Department, as each site is different and the duration and quality of the by-pass is different. It is determined at the location of the spill, quality and effected area what steps are taken and what type of warnings are posted. The Health Department makes this determination. The normal procedure would be to post the affected areas along the coast line and with signs that there was a sewage spill and that the affected areas should not be used for any recreational activates until the Health department deems the area safe. MRWPCA has the necessary signage to post the affected areas; additionally the Health Department also has official posting materials. G. Water Quality Sampling and Testing The Agency has a very aggressive sampling program. If there is an incident, Agency personnel sample up stream, entry point, and downstream of the affected area. These samples are collected and taken to the Agency Lab for analysis. Most Field Maintenance trucks carry sample kits on them and if they do not have the kits the Agency s Source Control personnel are called out to take the samples. Additionally samples are taken by the Monterey County Health Department for analysis at their labs. This gives us two samples from the same area to compare. The signage is not removed from the affected areas until the Monterey County Health Department declares the area safe. The key task here is that the scene is not secured or opened up until samples are taken and not declared safe until the County validities clean samples. Sampling protocols are followed in accordance with our Lab and our Source Control standard operating procedures. Lab and Source Control employees are trained to these standards. H. Investigation and Documentation The investigation of an incident starts as soon as there is a problem, MRWPCA doesn t have any collection systems to examine case hot spots or deteriorating collection systems lines so video investigations are not used. Investigations follow this basic check list: 1) Cause of incident (Equipment failure, natural, or man-made/operator error) 2) Review of Preventative Maintenance (Check Lists and CMMS) 3) Condition of station or pipe line (to include pictures of facility and effected areas) 4) Record keeping (seeing if problem was avoidable) 5) Operator actions Once the information is gathered a report is developed using the CIWQS reporting tool online and is followed-up with until complete to ensure the initial information is correct. The initial report is sent in as soon as possible and then a more accurate up-to-date report is submitted within the time lines laid out in the GWDR.

74 I. Regulatory Notification and Reporting The agency uses the notification check list in Appendix VI-1 to make notifications to all necessary agencies, key to the notification process is the 2 hour requirements to contact state OES. MRWPCA uses the same time line to notify the RWQCB, for these reports we use the CIWQS reporting system. Additionally, Agency personnel contact all senior staff members to include but not limited to the General Manager, Assistant General Manager, Deputy General Manager, and other senior staff as necessary. Additionally, affected member entities Board of Directors and Public Works Departments are called if necessary, the Call back sheet lists who called, who was talked to and the time of the contact. J. Equipment Listed below is the current equipment list used for Maintenance and Emergency Response activities for MRWPCA. In addition MRWPCA belongs to the Waste Water Area Response Networks and has the ability to call for additional equipment if necessary.

81 Appendix VI-2: Lift Station Information

82 Appendix VI-3: 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 five 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. Step 1 Sketch the shape of the contained sewage (see Figure A). Step 2 Measure or pace off the dimensions. Step 3 Measure the depth at several locations and select an average. Step 4 Convert the dimensions, including depth, to feet. Step 5 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 Triangle: Area = base (feet) x height (feet) x 0.5 Step 6 Multiply the area (square feet) times the depth (in feet) to obtain the volume in cubic feet. Step 7 Multiply the volume in cubic feet by 7.5 to convert it to gallons. Figure A: Common Shapes and Dimensions used for Estimating Spill Size

83 Method 3: Duration and Flow Rate 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 flow rate. The methods of estimating duration and flow rate 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 a few 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. 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 light-colored residue. From 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. Flow Rate The flow rate is the average flow that left the sewer system during the time of the spill. Two common ways to estimate the flow rate are described below: 1. San Diego Manhole Flow Rate Chart: This chart, included as Appendix VI-F-1, shows sewage flowing from manhole covers at a variety of flow rates. The observations of the field crew can be used to select the appropriate flow rate from the chart. If possible, photographs are useful in documenting the basis for the flow rate estimate. 2. 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 eight to ten gallons per hour per connection.

84 For example: 22 upstream connections x 9 gallons per hour per connection Spill Volume = 198 gallons per hour 60 minutes per hour = 3.3 gallons per minute Once duration and flow rate have been estimated, the volume of the spill is the product of the duration in hours or days and the flow rate 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
