19 - SSMP RecertificationITEM NO. 19 Costa Mesa Sanitary District Memorandum To: Board of Directors ...an Independent Special District From: Scott Carroll, General Manager Date: July 31, 2013 Subject: Sewer System Management Plan (SSMP) Recertification and Implementation Schedule of Audit Findings Summary On June 27, 2013, the Board of Directors received an internal audit report of the District's Sewer System Management Plan (SSMP). The audit was performed by Environmental Engineering & Contracting, Inc. (EEC) in which they found four minor nonconformance issues. Staff has prepared an implementation schedule to complete the minor nonconformance issues. In addition, staff has completed amending the SSMP to reflect the changes that have occurred in the last two years since the SSMP was last amended and certified by the Board. Staff Recommendation That the Board of Directors: 1. Approves amending and recertifying the SSMP; and 2. Approves the Implementation Schedule of the audit findings. Analysis In compliance with the Statewide General Waste Discharge Requirements (GWDR) for Sanitary Sewer Systems (State Water Resources Control Board Order No. 2006-003 - DWQ), the District developed and implemented a comprehensive Sewer System Management Plan (SSMP), with the primary objective of reducing and preventing Sanitary Sewer Overflows (SSOs). A key requirement of the SSMP is that routine internal audits be performed to evaluate the effectiveness of the SSMP as well as the District's compliance with the SSMP elements. Protecting our community's health and the environment by providing solid waste and sewer collection services. www.crosdca.gov Board of Directors July 31, 2013 Page 2 of 3 CMSD entered into an agreement with EEC to perform a self -audit of the Districts' SSMP and EEC provided their findings to the Board on June 27, 2013. EEC identified several minor nonconformance issues that can be easily corrected. Attachment A is a list of the minor nonconformance issues along with the scheduled deadline for completion. In addition, staff has completed amending the SSMP to reflect the changes that have occurred in the last two years since the SSMP was last amended. Some of the changes to the SSMP include adding new programs such as: • Residential FOG Recycling Program • Mainline Cleaning Program • Force main Rehabilitation Program Attachment B is a copy of the amended SSMP Strategic Plan Element & Goal This item complies to the objective and strategy of Strategic Plan Element 1.0, Sewer Infrastructure, which states: "Our objective is to collect and transport wastewater to meet the needs of existing and future customers. " "We will do this by the careful management of the collection infrastructure using prudent planning and maintenance, with financial strategies to maintain sufficient capacity and respond to changing regulatory demands." Legal Review Not applicable Financial Review There are no financial impacts for revising the SSMP. All revisions were performed by in- house staff. The minor nonconformance issue for reevaluating the system wide cleaning frequency may have a financial impact to the District depending on the course of action taken, if any. Staff will report back to the Board if a financial impact is going to occur. Public Notice Process Copies of this report are on file and will be included with the entire agenda packet for the July 31, 2013 Board of Directors regular meeting at District headquarters and on District's website.

GOAL A. INTRODUCTION The Costa Mesa Sanitary District (CMSD) is an independent special district governed by an independent five member Board of Directors elected at large by the residents. The District was formed in 1944, nine years before the City of Costa Mesa was incorporated, and provides sewer service and solid waste collection. The boundaries of the District include the entire City of Costa Mesa and portions of the City of Newport Beach and the unincorporated territory of the County of Orange. The District serves a residential population of approximately 116,700 plus various public, commercial, industrial and retail land uses. The District's facilities include 224.2 miles of mainline, 108.8 miles of private property sewer lateral pipelines, 24,870 service lateral connections, 4,650 manholes and 20 pumping stations. A detailed list of the sizes and lengths of the District owned sewer lines can be found in the Costa Mesa Sanitary District's Sewer Master Plan. The District's headquarters is located at 628 W. 19th Street, Costa Mesa and the District's Yard is located at 174 W. Wilson Street, Costa Mesa. The yard facility became operational in October 2010 and in February 2011, the U.S. Green Building Council (USGBC) certified the District Yard as Platinum LEED (Leadership in Energy and Environmental Design) for demonstrating the building uses of sustainability practices and environmental protection. Platinum LEED is the highest certification awarded by USGBC. In order to further the goal of a successful and comprehensive sewer system program, the CMSD Board of Directors established an Operations Committee that is comprised of two Directors, engineering staff and administrative staff. The committee meets monthly and reviews in detail all facets of the sewer program. This allows the Directors and staff to become knowledgeable and intimately involved in furtherance of the program. On Saturday, February 23, 2013, the Santa Ana River Basin Section (SARBS) of the California Water Environment Association (CWEA) named the Costa Mesa Sanitary District (CMSD) as the recipient of the 2012 Collection System of the Year award. SARBS, which boundaries include Orange, Riverside and San Bernardino Counties, is one of 17 geographical local sections of CWEA that trains and certifies wastewater professionals and promotes sound policies to benefit society through protection and enhancement of statewide water environment. On April 19, 2013, CMSD won the award again from CWEA. The designation of `Collection System of the Year' is one of the most prestigious SARBS /CWEA awards which recognizes an agency's significant accomplishments, safety record, training program, regulatory compliance, maintenance program along with documented administrative and emergency procedures. The Santa Ana Region of the State Water Quality Control Board oversees the water quality in the local waters of the State, particularly the Pacific Ocean and the Newport Beach Upper and Lower Bay. The beaches along the coast have been closed numerous 1 COSTA MESA SANITARY DISTRICT -SSMP 2/25/13 times due to contaminated surface water runoff and sewer spills and the closures have impacted the economy associated with summer beach activity. In response to the beach closures, the Regional Water Quality Control Board adopted new storm drain and sewer regulations. The sewer regulations, termed the Waste Discharge Requirements (WDR), were adopted on April 26, 2002, and applied to all the sewer system owners in Orange County whose lines are tributary to the Orange County Sanitation District treatment plants. Therefore, these regulations applied directly to the Costa Mesa Sanitary District. Subsequent to the regional order, on May 2, 2006 a statewide WDR was adopted and the local order was rescinded. One of the requirements of the WDR is the preparation and implementation of a comprehensive Sewer System Management Plan (SSMP). By preparing and practicing the procedures in the plan, the occurrence of sewer spills should decrease. This update to the SSMP will reflect the changes occurring at the District since the SSMP was last revised. Along with the recommendation to the Board of Directors to certify and adopt the SSMP is to also direct District staff to continually update the plan and bring it back to the Board at appropriate intervals for approval. The Costa Mesa Sanitary District recognizes the importance of protecting ocean water quality by preventing sewer spills and has historically taken a proactive approach to comprehensive sewer system management. B. REGULATORY BACKGROUND The Costa Mesa Sanitary District lies in Region 8 of the State Water Resources Control Board. The Region 8 WDR adopted in 2002 was partially in response to the Orange County Grand Jury report that analyzed ocean water pollution and identified grease in sewer lines as a substantial cause of sanitary sewer overflows (SSOs). Along with the WDR, the Regional Water Quality Control Board (RWQCB) also adopted Monitoring and Reporting Requirements in order to insure consistent and accurate sewer spill reporting. After the State Water Resources Control Board viewed the success of the regional WDR, a statewide order was adopted and the local order rescinded. The statewide order is nearly identical to the regional order and covers all sewer system owners in the State of California who own one mile or more of sewer lines. The statewide order is Order No. R3- 2006 - 0003 -DWQ, Statewide General Waste Discharge Requirements for Sanitary Sewer Overflows, (SSOs) and was adopted on May 2, 2006. The Costa Mesa Sanitary District Sewer System Management Plan (SSMP) is tailored to meet this order. The SWRCB developed the WDR to promote uniformity in the management of California's wastewater collection systems and reduce SSOs. The SWRCB found that cities and districts that have implemented SSMPs similar to this have been effective not only in improving spill reporting, but also in mitigating SSO impacts. Data also supported the conclusion that better collection system management will benefit water quality and prolong the life of sanitary sewer systems. 2 COSTA MESA SANITARY DISTRICT -SSMP 2/25/13 The SWRCB may regulate sanitary sewer overflows based on authority in the Federal Clean Water Act (EPA 2002) and the Porter - Cologne Water Quality Control Act, Section 13263 (California Water Code of Regulation 2006). C. PURPOSE AND GOALS OF THE SSMP This document has been developed to comply with WDR R3- 2006 - 003 -DWQ and sets specific wastewater collection system requirements and upholds State water quality standards. The WDR requires permittees to prepare and implement a SSMP in order to: • Provide a plan and schedule to properly manage, operate, and maintain all parts of the sanitary sewer system in order to provide reliable service in the future, • Reduce and prevent SSOs, • Help mitigate any SSOs that do occur. Sanitary sewer overflows are overflows from sanitary sewer systems of domestic, industrial, and/or commercial wastewater. SSOs may cause a public nuisance, particularly when untreated wastewater is discharged to waters designated for contact recreation. Proactively manage the sewage system CMSD operates in a way that prevents SSOs. 3 COSTA MESA SANITARY DISTRICT -SSMP 2/25/13 II. ORGANIZATION A.

C. CHAIN OF COMMUNICATION FOR REPORTING SSOs After receiving a complaint or report of a potential SSO, the Maintenance Supervisor and the District Engineer are notified. In the case of a power failure or other emergency within a pumping station, an alarm auto - dialer system will call to inform six District members of the emergency in the following order: Maintenance Supervisor, Maintenance Workers III and I (there are two MW I and one MW III within the organization), District Engineer and then the General Manager. The first responder will report an overflow or hazard immediately to the District Engineer and then to the General Manager. The District's Engineer is responsible for reporting the overflow to the appropriate regulatory agencies. The response process for SSOs is described in section VI in more detail. The District's Engineer is a Legally Responsible Official (LRO) and is responsible for overseeing the reporting process. The District Engineer receives the spill report from the Maintenance Supervisor and drafts up the required report with consideration given to volume calculations, vacuum and wash down operations, cause of spill, timeliness of response, etc. After discussions are complete, the report is finalized, reviewed by the General Manager and then transmitted to the appropriate authorities by the District Engineer. The District reports all spills except private property spills where the spill is contained on -site. As a first priority during a sewer spill, District staff and field crews notify the appropriate agencies by phone that a spill has occurred instead of depending on the report as a means of notification. If the spill is significant or the result of a major emergency involving CMSD sewer lines or pumping stations, the District follows a pre- described procedure. The following page contains the Organizational Chart showing the lines of authority of all the administrative and field staff and their respective responsibilities during such an emergency. In order to properly respond to a sewer system emergency that requires reconstruction of District sewer facilities, the District placed its long standing high quality contractors on emergency services agreements. The list contains contractors who have demonstrated expertise in pumping station construction, pipeline construction, televising, and pipeline rehabilitation utilizing trenchless technology. These contractors are staffed with well - experienced workers who are able to handle the scope of emergencies experienced in the District.

COSTA MESA SANITARY DISTRICT - SSMP III. LEGAL AUTHORITY 2/25/13 The District must demonstrate, through sanitary sewer system use ordinances, service agreements, or other legally binding procedures, that it possesses the necessary legal authority to: (A) Prevent illicit discharges into its sanitary sewer system. (B) Require that sewers and connections be properly designed and constructed. (C) Ensure access for maintenance, inspection, or repairs for portions of the lateral owned or maintained by the District. (D) Limit the discharge of fats, oils, and grease and other debris that may cause blockages, and (E) Enforce any violation of its sewer ordinances. A. PREVENT ILLICIT DISCHARGES INTO ITS SANITARY SEWER SYSTEM The Sanitary District has the power to install sewers and enact regulations related thereto, including the prohibition of private sewer systems and requiring all inhabited property to be connected to District sewers (Health and Safety Code Section 6400 et seq.) Once exercised, a sanitary district's power is controlling over any general law city or county regulation pertaining to the same subject (Home Gardens Sanitary District v. City of Corona (2002) 116 Cal.Rptr.2d 638.) A permit from the District is required to connect to, use, or maintain a connection to the District's facilities (District Operations Code Section 6.04.060 (a)). Any person, firm or corporation that connects or discharges to the District's sewerage system without a valid permit is guilty of a misdemeanor (District Operations Code Section 6.04.060 (f)). In the Costa Mesa Sanitary District, illegal connections are usually connections to the sewer system by property owners who have drainage problems due to flat areas and low spots and who solve those problems by draining those areas to an inlet that is connected to the sewer system. When instances of these illegal connections are found, the property owner is required to immediately remove the connection. B. REQUIRE THAT SEWERS AND CONNECTIONS BE PROPERLY DESIGNED AND CONSTRUCTED Results of District -wide video inspection show that vitrified clay pipe will remain in excellent condition if proper construction practices are followed. Providing continuous inspection during the installation procedure insures the proper construction practices are followed. Continuous inspection of other utilities being installed in the vicinity of the sewer lines insures proper protection methods are provided for the sewer lines and lengthens the life expectancy of the lines. C COSTA MESA SANITARY DISTRICT - SSMP 2/25/13 Title 6 of the Operations Code regulates sewer construction. All sewer construction must be in accordance with District standards (Section 6.01.010). The type of materials and inspection requirements by District staff are provided in Chapter 6.01. The Sanitary District has its Standard Plans and Specifications for the Construction of Sanitary Sewers that insures the sewer lines and connections are properly designed and constructed. The District's specifications by reference incorporate the Standard Plans and Specifications for Public Works Construction (Green Book), which assists in insuring proper design and construction of sewer facilities. C. MAINTENANCE, INSPECTION, OR REPAIRS OF SEWER LATERALS The Costa Mesa Sanitary District does not own or maintain the sewer laterals within the District boundary. By ordinance, the sewer laterals, even when located within public streets remain private and are owned and maintained by the property owner (District Operations Code Chapter 6.02). The District does require CCTV inspection and repairs of private sewer laterals under certain conditions that will assist in preventing sewer spills (District Operations Code Chapter 6.03). D. LIMIT THE DISCHARGE OF FATS, OILS, AND GREASE AND OTHER DEBRIS THAT MAY CAUSE BLOCKAGES Every owner, tenant and persons using property shall have a duty not to cause, permit or allow the accumulation of grease in the District's sewer line so that sewage spills may occur. Such persons shall use reasonable methods to reduce grease accumulation in the District's sewer lines including but not limited to reducing or eliminating the grease that is deposited in the sewer and utilizing enzymes and similar products that prevent grease build -up. No person shall discharge grease into the sewer system so as to cause an accumulation in the District's lines so as to substantially contribute to the possibility of a sewage overflow (District Operations Code Section 6.07.040). On November 21, 2011, the District implemented a convenient program for residents to dispose of unwanted cooking grease. In a partnership with the Orange Coast College (OCC), residents can bring any type of grease filled jugs, bottles and/or containers to the OCC Recycling Center located on Adams Street between Harbor Blvd and Fairview Road in Costa Mesa. The grease is poured into one of the two 50 gallon vats that are stored in front of the recycling center. When the vats are full, a contractor will arrive to pump out the grease and then transport the material to a rendering facility where the grease is recycled into useable products such as candles, soap, pet food and biofuel for automobiles. The program has successfully collected and recycled over 1,000 gallons of grease. No Food Service Establishment shall discharge into the District's system without obtaining a permit from the District describing the business operations and discharge and any FOG prevention measures being undertaken or to be undertaken to reduce the 10 COSTA MESA SANITARY DISTRICT - SSMP 2/25/13 discharge of FOG into the District's system in accordance with this chapter (District Operations Code Section 6.07.050). The District has adopted Ordinances No. 51 and 81, which control fats, oils, and greases (FOG). Grease has been identified as the number one cause of sewer line stoppages and spills by the Sanitary District and by the Orange County Grand Jury who conducted a countywide study. Because of this finding, FOG has been identified as the most important first step in improving sewer system reliability. As stated earlier, the District has the legal authority to control discharges to the sewer system for all sewer facilities located on private property that are outside any structures located on the property. This authority allows the District to require grease interceptors, as by Code the interceptor is located outside the building. The legal authority for plumbing fixtures inside a building rests with the local agency building department. The Sanitary District has been working with the Building Officials of the three building departments within the District's service area (Costa Mesa, Newport Beach, and Orange County) to urge adoption of FOG reduction policies, which will be consistent with the goal of removing FOG from the sewer system. The District controls the discharge of other debris into the sewer system through its ordinances and through the ordinances of the Orange County Sanitation District, whose regulations prohibit unapproved debris from being discharged into the system. Both the Costa Mesa Sanitary District and the Orange County Sanitation District only allow discharges from permanently install plumbing fixtures unless authorized by special discharge permit. E. ENFORCEMENT OF VIOLATIONS OF CMSD SEWER ORDINANCES The District has enacted an Operations Code by ordinance. Any person, firm, or corporation violating the penal provisions of this ordinance shall be guilty of a misdemeanor and punishable by a fine of up to one thousand dollars per day and /or up to six months in jail (Section 1.02.010). Violations of the connection permit provisions of the Operations Code are also subject to administrative citations (Section 1.06.010(d). Violations of the Operations Code may result in termination of service in accordance with Health and Safety Code Section 6523.2. 11 COSTA MESA SANITARY DISTRICT - SSMP 2/25/13 I li�l7_9 DI : 7: IV0 to] ► 1. 1` f-111ul.1ILIINW0 /:1► Eli WOWZIZH:7:1u1 A. THE CMSD SANITARY SEWER SYSTEM MAP The District has a hand -drawn Sewer Atlas that is continuously updated as new facilities are constructed. The Atlas shows the location of all sewer mains, manholes, laterals, pumping stations and pressurized sewer lines (force mains). The Atlas also has reference numbers to the particular construction plans that were used to build each portion of the system. In addition to the Sewer Atlas, plans of the sewer system are included in the Sewer Master Plan Update. The maps in the Master Plan are also updated as new facilities are constructed and are used in conjunction with the sewer line capacity calculations as a planning tool for the yearly Capital Improvement Program. Because the Sewer Atlas is a hand -drawn set of maps, and because a computerized GIS system can provide multiple planning tools such as sewer main cleaning maps, computerized maintenance management system (CMMS), and hydraulic modeling, the CMSD Board of Directors directed District staff at the regular meeting held August 27, 2009, to bring back a negotiated contract with Environmental Engineering and Contracting (EEC) to convert the District's mapping system to GIS. As of February 25, 2013, the GIS Atlas is 100% and the CMMS is 100% complete. The locations of all the storm water conveyance facilities are shown on separate maps prepared by the agencies owning the storm drains and copies of these plans in reduced size format have been distributed to the CMSD General Manager, District Engineer, Inspector, Field Crews, and Administrative Office. The District recognizes the link between a sewer spill and its travel in a storm drain facility to the receiving waters. The District has educated its Staff to understand the storm drain network and utilize it to capture a spill if it has entered the storm drain system. The District understands the NPDES regulations for storm drain system owners contain requirements prohibiting sewer system spills into the storm drains. The NPDES requires the storm drain system owners to adopt measures that will decrease the possibility of sewer spills reaching the waters of the state. B. PREVENTATIVE MAINTENANCE PLAN On July 26, 2012, the District approved a new cleaning method by dividing the District into five sections and cleaning slightly more than one -half of the system each year. This simpler approach will decrease travel time and increase efficiency by concentrating work in selected areas rather than having to drive to certain areas just to clean selected sewer lines. Cleaning sewers every two years is a safe and reliable practice that will not lead to backups and sanitary sewer overflows. Sewer lines requiring annual maintenance will continue being cleaned annually. Areas needing more frequent cleaning — known as hot spots or enhanced maintenance areas — are cleaned as frequently as necessary. These include the inverted siphons that run under flood control channels or commercial areas with multiple restaurants. The District has developed GIS maps of areas of the system requiring cleaning once per year and areas requiring cleaning once every two years. An example of an area 12 COSTA MESA SANITARY DISTRICT - SSMP 2/25/13 requiring cleaning once a year is the 15" VCP sewer main in Adams Avenue that handles a large service area. Examples of lines requiring cleaning once every two years are 8" lines in cul -de -sacs that only serve a few residences. The GIS maps and CMMS will provide an enhanced planning tool consisting of boundary lines around sewer sheds so they can be cleaned from the higher elevations to the lower elevations along with colored cleaning maps. Currently, the CMSD Maintenance Supervisor uses the GIS and CMMS to plan and document cleaning activities. With the recent addition of a new maintenance worker, District field crews now total four men including the Maintenance Supervisor. The increase in field crew size coupled with the recent purchase of a new sewer cleaning truck (Vac -con truck) gives the District the ability to perform regular sewer line cleaning. The District continues to use two sewer - cleaning crews, one in -house crew and one contract crew; however, the in- house crew is now responsible "maintenance cleaning" half of the system. The in -house crew works at the discretion of the Maintenance Supervisor and will also clean hot spots, washes out pumping station wet wells, responds to emergencies, and assists in the pumping station preventative maintenance program. In order to alleviate the extra time involved in cleaning and maintaining hot spots and lower the risk of SSOs, the District established two committees; Hot Spot and Pump Station Committees. Both committees include in attendance the General Manager, engineering and field staff, and the District's FOG consultant EEC. The committees meet approximately once every three months to analyze the hot spots and pump stations operational mode to determine improvements. Since inception of the committees, 95 original hot spot locations have been reduced to 43 locations and there has been zero SSOs caused by the District's pumping stations. Due to the dynamic nature of sewer pumping stations and the risk of large spills, in addition to the Maintenance Supervisor and one crewmember that have backgrounds in preventative maintenance of pumping stations, the District retains qualified contractors to perform routine and special maintenance on the pumping stations. The District uses JIMNI Systems and Xylem, Inc. for pump station maintenance. The Maintenance Supervisor keeps a spreadsheet tracking the dates and categories when preventative maintenance is performed at each pumping station. To enhance the District's SCADA alarm system for pumping stations, the District installed a more reliable system that eliminates false alarms and notifies staff when power is restored and/or when water levels are back to normal. The new system will reduce overtime and unnecessary response times. These improvements are now complete. The District's preventative maintenance program for pumping stations began years ago when staff obtained the recommended pump maintenance schedule from the pump manufacturer and for the rest of the piping, valves, and other equipment in the station and valve vault, the District used the recommended maintenance schedule provided by Schuler Engineering Corporation. Bruce Schuler is both a registered civil engineer and construction contractor and was requested to provide an outline for the program because of his extensive experience in construction and rehabilitation of pumping stations. Schuler Engineering Corporation is also one of the District's emergency contractors as 13 COSTA MESA SANITARY DISTRICT - SSMP 2/25/13 well as having bid and successfully constructed various District projects. The Maintenance Supervisor then captured the above information into a comprehensive spreadsheet, including expanding the categories and parameters, which is the working document for the maintenance of the pumping stations. In order to prevent private property sanitary sewer overflows from residential properties, the Board of Directors established Project #186 Sewer Lateral Assistance Program. The program provides matching funds of up to $1,600 per parcel for residents to construct a sewer cleanout or clean, repair, rehabilitate, or replace their sewer lateral. The program is funded at a yearly level of $200,000 exclusive of staff costs. Since the program's inception in July 2007, nearly 800 applicants have participated in the program with an approximate average reimbursement of costs of $1,050 per parcel. The program has prevented a significant number of backups from occurring and is very well received by the residents. The program is set to remain in the yearly budget. C. REHABILITATION AND REPLACEMENT PLAN As written in the Costa Mesa Sanitary District Sewer Master Plan Update, there are no known structural deficiencies in the sewer system. The District's 1989 -1993 video of the sewer system disclosed the few gravity line segments that necessitated point repairs and these repairs were handled in the early 1990s. Since then the District has completed small yearly televising projects to stay ahead of needed repairs and to supplement the FOG program. The District re- televised the entire system under Project #175 from 1/1/06 to 3/15/06 under a cooperative project with the Orange County Sanitation District (OCSD). The Sanitation District is concerned with the excessive rainwater and ground water arriving at their two treatment plants during the rainy season. Water may enter the sewer system through infiltration (groundwater entering the sewer system through cracks in sewer lines and manholes) and inflow (surface water entering the sewer through the holes in manhole covers when streets become flooded or through backyard illegal connections that drain rainwater). Termed UI for Infiltration/Inflow, the water places a large strain on the sewer treatment plants as the flows doubles from 240 million gallons per day (MGD) to 480 MGD. On June 19, 2012, the District's Operations Committee received a presentation about the CMSD'S I/I program and a plan to plug and seal an additional 200 manholes to reach a total of 1,008 manholes plugged and sealed out of 4,650 manholes. In addition, staff purchased standard manhole covers without vent holes to alleviate the need to plug said vent holes. The Board of Directors has approved a yearly repair projects in the Capital Improvement Program (CIP) as demonstrated by the projects completed below in the last two years: • Project #129 — Bristol Street Sewer, Phase II — replaced 700 linear feet of sewer main by using no -dig technology pipe bursting. Total cost including construction and design: $611,061. The budgeted amount was $634,324. 14 COSTA MESA SANITARY DISTRICT - SSMP 2/25/13 • Project #164 — Root Control Program — Removed offending roots from twelve hot spot locations and then installed a short section of cured -in- place -pipe (CIPP) over the joint to prevent recurrence of the roots. Total cost including construction and design: $104,570. The budgeted amount was $121,400. • Project #171 — Irvine Pump Station Force Main — Replaced 3,000 linear feet of sewer force main by slip ling a new high density polyethelyne (HDPE) line inside the existing pipe. Total cost including construction and design: $379,087. The budgeted amount was $405,665. • Project #185 — System Wide Sewer Reconstruction, Phase I — Reconstructed 95 Grade 5 deficient line segments. Total cost including construction and design: $767,275. The budgeted amount was $1,086,000. • Project #189 — Rehabilitating Six Sewers Transferred to CMSD — Replaced 602 feet of sewer main to remove 90% sag and rehabilitated manholes. Total cost including construction and design: $672,700. The budgeted amount was $697,666. • Project #190 — Canyon Force Main Rehabilitation — CIPP 545 feet of sewer force main. Total cost including construction and design: $125,433. The budgeted amount was $141,000. • Project #191 — Emergency Work on Santa Ana & 23rd Street Force Mains — Relined 1,500 feet of sewer force mains and replaced piping and valves in and around two sewer pump stations. Total cost including construction and design: $758,726. The budgeted amount was $850,000. • Project # 192 — System Wide Sewer Reconstruction, Phase II — Reconstructed 73 Grade 5 deficient line segments. Total cost including construction and design: $184,675. The budgeted amount was $1,115,361. The total cost spent on the CIP projects mentioned above is $3,603,527. The sewer pumping stations and pressurized sewer lines (force mains) require a more aggressive maintenance program. The 20 pumping stations have equipment that operates in short cycles throughout each hour of the day. The stations are monitored and maintained daily and because of the continuous operation, any deficiencies are readily apparent. Maintenance is ongoing and on an as- needed basis. The pumping stations are upgraded or rebuilt as soon as the maintenance staff believes the risk of problems begins increasing. As part of the Sewer Master Plan, a chart was prepared with installation dates, line size, pipe material, flow rate, and pressure for each of the 20 force mains. Because these lines flow under pressure, they have a shorter life expectancy than gravity sewers. Whereas gravity sewers can be video inspected while they are in operation, force mains must be totally shut down and the system by- passed in order to allow the camera to travel down the line. A replacement schedule has been prepared, which is based on the anticipated life expectancy of each force main. The District has also kept records of previous ruptures, if any, and the causes. District staff has met with a corrosion specialist to 15 COSTA MESA SANITARY DISTRICT - SSMP 2/25/13 consider field- testing the force mains and soils conditions to better predict the life expectancy of each force main. The current yearly sewer charges provide approximately $1.6 million per year for the Capital Improvement Program. By law, these funds must be used for maintenance and rehabilitation projects and not for expansion projects. In addition to these funds, various other items in the budget are dedicated to sewer system maintenance and operation. On July 17 -18, 2012, the District embarked on an innovative process to assess the condition of force mains. The District hired a company called, Pipeline Inspection and Condition Analysis Corp. or PICA, to provide direct condition assessment of force main pipes through the use of in -line inspection tools. Direct condition assessment is the only way for Asset Managers to truly know if a pipeline can be repaired or rehabilitated, or if the pipeline truly needs to be replaced. "Good Decisions start with Good Information ": this is the premise under which PICA operates. PICA provided accurate measurements of remaining wall thickness for the Santa Ana Avenue and 23rd Street force mains. Their unique, patented technology can "see" through liners, scale and tubercles to detect graphitization and pitting, erosion and cracks. Their tools use electromagnetic technology which does not require the sensors to be in contact with the pipe wall inside the pipe. The tools have equal sensitivity to wall - loss regardless of whether it is on the inside or outside of the pipe. PICA can detect leaks, of course, but they can also detect thinning that will lead to leaks in the near future, allowing the District to make proactive repairs to prevent the next leak. The PICA technology was able to determine that the Santa Ana Avenue and 23rd Street force mains had significant corrosion causing the walling thickness to be less than 20 %. Imminent failure was on the horizon, so armed with this information the District immediately performed emergency work by relining the force mains (Project #191). The District plans on using this technology for assessing all of the force mains. In September 2012, the District received the 2012 Innovative Project of the Year award for this project from the California Special Districts Association (CSDA). The District also established an Asset Management Fund for future sewer replacement for the time when the sewer system reaches its life expectancy. The fund was established in fiscal year 2012 -13 and has a current balance of $5,140,291. The Board of Directors directed staff to ensure the Asset Management Fund has enough funding to replace sewer infrastructure for the next thirty years. The Board also established an Earthquake Fund to replace sewer infrastructure that might be damaged in earthquakes. The Earthquake Fund has a current balance of $1,000,000. D. EDUCATION AND TRAINING On a yearly basis, the Maintenance Supervisor and field crew attend formalized collection systems training seminars. The seminars include use of combination vacuum/jetting vehicles, hoses and nozzles, sewer cleaning procedures, and emergency response including blocking storm drains and recovering spilled effluent. The Maintenance Supervisor is certified as a Grade 3 operator for collection system maintenance under the California Water Environment Agency (CWEA) certification Irli COSTA MESA SANITARY DISTRICT - SSMP 2/25/13 program. The District's Maintenance Worker III employee is certified as a Grade 1 operator for collection system maintenance under CWEA certification program and he is currently studying for the Grade 2 certification. The Maintenance Worker I employee is currently studying for the Grade 1 certification. CWEA requires a pre - determined number of education hours (contact hours) per year in order to maintain certification. The Maintenance Supervisor and the maintenance workers have receive formalized training from the ITT Flygt Corporation, the manufacturer of the pumps used in the majority of the 20 pump stations. The District Engineer is a member of the Orange County WDR Steering Committee and Orange County WDR General Group. As part of his activities, the District Engineer runs an education program consisting of a quarterly education seminar focusing on various aspects of a comprehensive sewer system management program. Seminar topics have included design and maintenance of sewer siphons, design and maintenance of sewer pumping stations, current no -dig technology advancements, education materials, etc. E. EQUIPMENT AND REPLACEMENT PARTS INVENTORY For the Sanitary District, keeping critical replacement parts available encompasses stocking spare pumps that can be used as replacements while pumps are serviced or replaced. The District attempts to use the same model pumps in as many stations as possible to simplify maintenance and replacement. The District also attempts to use the identical equipment in each of the pumping stations, including electrical panels, liquid level sensors, back up sensors, valves, by -pass connection, etc. The District normally uses contractors to work on the sewer lines. As described under the emergency response section of this report, the District has selected high quality contractors under on -going emergency service agreements to allow the District the ability to have contractors both on -call for normal work and on -call for emergency work. The District has the necessary equipment to work on the pumping stations with the exception of a crane large enough to remove the pumps from the pumping stations. However, in the fall of 2013, the District will acquire a new utility truck with a crane capable of removing large pumps. Under a Letter of Understanding (LOU) with the local water district, the Mesa Water District, the District's have a mutual sharing agreement. This has fostered into the Sanitary District requesting Mesa provide their crane as needed. The District may also rent a crane as it has done so in the past. In addition to small tools, the District has recently purchased a 2013 combination vacuum/jetting sewer cleaning truck. The District also has three trailers mounted emergency diesel generators, three bypass pumps, several trash pumps and a utility truck with hoist capable of lifting the small pumps. The Maintenance Supervisor has established an inventory of critical parts and equipment on hand. 17 COSTA MESA SANITARY DISTRICT - SSMP 2/25/13 V. DESIGN AND PERFORMANCE PROVISIONS A. STANDARDS FOR INSTALLATION, REHABILIATION AND REPAIR The District requires all new or rehabilitated sewer installations be tested and inspected pursuant to the provisions of Title 7 of the District Operations Code and a permit is required for such connections. The primary design and performance standards the District uses in design and installations of new sewer systems are: • Title 7 of the District Operations Code • The Costa Mesa Sanitary District Standard Plans and Specifications for the Construction of Sanitary Sewers • Standard Specifications for Public Works Construction ( "Green Book ") • American Public Works Association Standard Plans for Public Works Construction The standards listed above outline construction specifications for installing new sewer systems, pump stations, and other appurtenances; and for rehabilitation and repair of existing sewer systems. Design criteria include specifications for items such as pipe materials, minimum sizes, minimum cover, strength, minimum slope, trenching and backfill, structure standards, and other related provisions. All new construction, rehabilitation, or repair of the sanitary sewer system adheres to these standards. Additionally, the District has standardized its use of equipment in the pumping stations for ease of maintenance and replacement. This includes the pumps, liquid level indicators, electrical components, valves, piping and telemetry. The District is implementing no -dig pipeline rehabilitation as one of the methods for replacement. The Sanitary District considers no -dig technology to be the future answer to pipeline rehabilitation as systems reach their life expectancy. Parts of the Sanitary District's system will be 100 years old in 2050 and although vitrified clay pipe may have a life expectancy far greater than 100 years, the District believes no -dig rehabilitation methods will be the standard rehabilitation practice. B. STANDARDS FOR INSPECTION AND TESTING OF NEW AND REHABILITATED FACILITIES The District's standard public works contract provides the work is not placed into service and accepted by the Board of Directors until inspection and testing is completed. Additionally, no dedication will be accepted and no tie into District facilities will be allowed where the District Engineer has not approved the plans and drawings and has not inspected the project during its course of construction (District Operations Code Section 6.01.070). The District provides continuous inspection during the construction of sewer facilities and believes that proper installation is the key element to insure proper operation and COSTA MESA SANITARY DISTRICT - SSMP 2/25/13 maximum life expectancy. Inspection and testing of new or rehabilitated facilities ensures that the established standards are being implemented in the field. Acceptance testing for gravity sewers can include: low pressure air test or water test to identify leakage, mandrel test to identify deflection of flexible pipe, and television inspection to identify grade variations or other construction defects. CMSD adheres to these standards for inspection and testing of new or rehabilitated facilities that are outlined in the above listed standards. lut COSTA MESA SANITARY DISTRICT - SSMP 2/25/13 VA�11i /WRI1101ATAfluiN.'T jN [IMAR*111)LMDI UARL1 The Overflow Emergency Response Plan (OERP) is developed as part of the CMSD Sewer System Management Plan. The purpose of the plan is to establish guidelines and measures to protect public health and the environment in case of an accidental overflow. In the case of an overflow, CMSD shall dispatch the appropriate crews to investigate, identify the cause, and provide appropriate action to minimize the effects of the overflow on public health and quality of surface waters. The OERP further specifies the required notification and reporting that is necessary for local and state agencies. Appropriate CMSD personnel will be required to read the OERP and familiarize themselves with the procedures. The OERP should be kept in an easily available location for all utility personnel and public access reference. A. SSO NOTIFICATION PROCEDURES Outside of regular business hours, the District's general phone number (949) 645 -8400 has information on who to call for after -hours emergencies, and the Costa Mesa Police Department Dispatch follows District procedures for SSO's. Because the majority of after -hours emergency calls for gravity sewer SSOs pertain to private small size sewers, the first responder is C &R Drains, a local plumber. C &R Drains is under contract to the District to provide first responder service and has the ability to unclog any private sewer backup. If upon arrival at the SSO C &R Drains finds the backup to be in a District sewer main, C &R Drains will call the CMSD Maintenance Supervisor who lives locally and who will respond with the District's combination jetting /vacuum sewer cleaning truck. If there is a sewer alarm from one of the sewer pumping stations, the hierarchy for the alarm auto - dialer system is the CMSD Maintenance Supervisor, the Maintenance Workers III, both Maintenance Workers I, the District Engineer and then the General Manager. Besides C &R Drains, the District also has National Plant Services, a sewer cleaning company who is another emergency responder under contract to the District, ready to respond. For emergencies at pump stations, the District has a contract with JIMNI Systems as the first responder. All District Staff and field crews have preprogrammed cellular phones to facilitate instant communications. Should cellular phone communications be down during the emergency, the District has low band two -way radios for use to communicate between District staff, field crews and the Water Emergency Response Organization of Orange County (WEROC) if need be. B. APPROPRIATE RESPONSE TO ALL OVERFLOWS District policy is to respond to all spills within the District — and even provide mutual aid outside the District — whether on public or private property and to take all steps possible to prevent the spills from reaching the storm drains, flood control channels, or waters of the State, all in accordance with the waste discharge requirements. 20 COSTA MESA SANITARY DISTRICT - SSMP 2/25/13 Organization of this document details the lines of authority and responsibilities of District personnel during an emergency. Because the District provides only sewer service and trash collection service, the District has equipment and manpower dedicated solely to sewer system maintenance, operation, and emergency response. C. REGULATORY NOTIFICATION PROCEDURES If a SSO occurs, it is required that certain regulatory agencies be contacted. The following reporting criteria explain when notifications should be sent and the various forms that are required. Regulatory notification procedures are administered by the District's Engineer. 1) Oral Notification As a first priority during a Category 1 sewer spill, District staff and field crews immediately notify the appropriate agencies (not later than two hours after becoming aware of the discharge) by phone that a spill has occurred following the direction to do so, such that reporting can be provided without substantially impeding cleanup or other emergency measures. The District follows the same procedure for Category 2 spills instead of depending on a written report as a means of notification, well within the requirement for Category 2 SSOs of reporting to the Online SSO Database within 30 days after the end of the calendar month in which the SSO occurs. The District also verbally reports all private property spills that are not fully recoverable immediately upon discovery. Category 1 sewer spills are spills from the District's sanitary sewer system equal to or greater than 1,000 gallons or where the spill enters waters of the state or where the spill enters a storm drain system and is not recovered, and require notification to the appropriate State agencies. Each of the following must be notified in the case of a Category 1 and Category 2 sewage spill: Orange County Health Care Agency Environmental Health Department: 714/433 -6419 or 6281 After Hours — Control 1 714/628 -7008 Regional Water Quality Control Board — Santa Ana Region: 951/782 -4130 Fax 951/781 -6288 Any discharge of sewage into or onto a waterway must also be reported to California Emergency Management Agency (CaIEMA) (formerly OES): CaIEMA: 800/852 -7550 Fax 916 - 262 -1677 21 COSTA MESA SANITARY DISTRICT - SSMP 2) Written Report 2/25/13 The District reports all Category 1 spills within 3 business days as required in the Monitoring and Reporting Program, and the District also reports all Category 2 spills within 3 business days. Both Category 1 and Category 2 spills are included in the monthly spill report. The District does not submit written reports of private property spills, only verbal reports when it is discovered a private property spill is not, and cannot be, fully contained. Where there are no public spills during the month, the District submits a monthly no -spill report. The District reports the spills in accordance with the on -line CIWQS reporting forms and State Water Resources Control Board Monitoring and Reporting Program No 2006 - 0003 -DWQ (As Revised by Order No WQ 2008-0002 - Exec) SSO Reporting Timeframes. The District's Engineer is responsible for overseeing the reporting process. The District Engineer receives the spill report from the Maintenance Supervisor and drafts up the required report with the consideration given to volume calculations, vacuum and wash down operations, cause of spill, timeliness of response, etc. After discussions are complete, the report is finalized and submitted to the General Manager for review. Once approved by the General Manager, the District Engineer transmits the spill report to the appropriate authorities. As required in the Monitoring and Reporting Requirements, the District also completes the annual questionnaire by the end of December each year. D. TRAINING PROCEDURES The role of each person during an emergency has been established and is clear and concise. The District has pre - established responsibilities for staff members that work concurrently with the field crews to provide an efficient response. All CMSD staff members are required to read and sign off having read and understood the sewer system management plan and spill reporting form. Maintenance workers are required to keep copies of the Sewer System Management Plan and the spill reporting form in each vehicle. If the emergency is during normal working hours, all maintenance workers and the supervisor are working as appropriate to handle the emergency. At the same time, District Staff is positioned as follows: • The General Manager will be in District Headquarters providing overall direction and setting priorities. • District Engineer will also be in District Headquarters to gather and assess information and develop an action plan to arrange various resources such as contractors, pumper trucks, and other independent contractors. The preprogrammed cell phones that the field crews and staff have allow instant communications and organization from the District office. • The CMSD Inspector is in the field and while providing direction to the maintenance workers in the field reporting continuously to the District Engineer to insure the best possible actions are taken. 22 COSTA MESA SANITARY DISTRICT - SSMP 2/25/13 • The Maintenance Supervisor is in the field responding to the action plan developed by the District Engineer, as well as documenting the situation with pictures and verbal reports back to the District office. The Maintenance Supervisor will immediately verbally report any sewer spills to the required agencies and as soon as possible file the written report. • Maintenance Workers are in the field responding to the action plan developed by the District Engineer. • The Executive Assistant/Deputy Clerk of the District is keeping the Board of Directors apprised of the situation via e -mail, cellular telephone or in person. • The Permit Technician, Management Analyst and /or Administrative Assistant is working in the District Headquarters providing resources to staff that may include obtaining equipment, food, water, first aide, etc. • The Finance Manager is tracking all costs, including staff hours, related to the operations in order for the District to be eligible for reimbursement in case the emergency situation is declared a disaster by the Governor. • The Administrative Services Manager is procuring and maintaining essential equipment and supplies. E. EMERGENCY RESPONSE OPERATIONS The District's field crews respond to all emergencies, and if needed, the District utilizes its list of pre- approved qualified contractors. The list of contractors is attached to this SSMP, and the SSMP will be carried in each field vehicle as well as being in the appropriate administrative offices and in the Sewer Master Plan. The independent contractors on the list have demonstrated exceptional workmanship over the years and the District has signed emergency services agreements on file so there will be no delays in responding to an emergency. Both the District and the emergency contractors have traffic control equipment that can be used for crowd control. F. PROGRAM TO CONTAIN AND PREVENT SEWAGE DISCHARGES TO SURFACE WATERS The District shall continue to maintain one in -house two -man field crew, one contract two -man, and a supervisor who are responsible for cleaning the system and for being the first responders in the event of a sewer main spill. During normal working hours, the response time is a few minutes and after hours the contract plumber or maintenance supervisor are usually on -scene within one -half hour. 23 COSTA MESA SANITARY DISTRICT - SSMP 2/25/13 The District has one combination jetting /vacuum truck, traffic control equipment, three by -pass pumps and hoses, several trash pumps and three trailer- mounted standby generators. The District field crews are required to use mats to block the catch basin entrances to the storm drains and use the vacuum truck to vacuum up spills and the wash down water. The District also uses the storm drain system as a containment device if needed. The outlet to the storm drain is blocked and the spill and wash down water are vacuumed from the line. The impact of spills is minimized by washing the spill down with water to the maximum extent possible. The Orange County Health Care Agency has requested that only fresh water be used because disinfectants pose their own problems. The District relies on the Orange County Health Care Agency ( OCHCA) for monitoring water quality and posting beach closures. All spills are reported immediately to the OCHCA office. The District uses the following four -step approach to private property SSOs that are discharging to the public right -of -ways: • First, field crews block the storm drains so discharges will not enter the system. If they already have, the District uses the storm drain as a containment device and extracts the discharge and water used to flush the system from a downstream point in the system. • Secondly, the District sandbags the public right -of -way to prevent further discharges from leaving the property. • Thirdly, the District notifies the property owner or management company of the spill and directs them to hire an emergency plumber to clear the system. District crews never leave the site until the problem is resolved and the spill is stopped and cleaned up. • Fourthly, in addition to the regular reporting of spills, the District requests the Orange County Health Care Agency notify the property owner of the spill and demand corrective action. The District Board has entered into contracts to perform emergency work that are preapproved with contractors that already possess the license and insurance to perform such work. The District Board has enacted an ordinance, District Operations Code Section 4.04.120(a), that authorizes the General Manager to order emergency work in accordance with Public Contracts Code Sections 22035 and 22050. Upon the General Manager's discretion, C &R Drains will be called out to alleviate a private property backup if the property owner or property manager is unavailable. In addition, the District has also developed an Emergency Response Plan for the majority of the sewer pumping stations within the District. The stations without the emergency response plans are planned for abandonment. The Emergency Response Plans contain the procedures to be implemented to prevent an SSO should the pump station become inoperable or a major emergency, such as a downed bridge that contains 24 COSTA MESA SANITARY DISTRICT - SSMP 2/25/13 a force main, occurs. The plans include calculations of the number of pumper trucks required, two different pre - determined driving routes to two disposal points while avoiding potential high traffic or disaster points such as bridges, emergency contact list, etc. These major emergency plans were completed in July 2009 and a copy is present in all the field vehicles, in the Maintenance Supervisor, General Manager and District Engineer's offices. 25 COSTA MESA SANITARY DISTRICT - SSMP VII. FOG CONTROL PROGRAM 2/25/13 Studies by the District have identified the main causes of SSOs within the District and efforts have been prioritized to eliminate the causes. The Management Analyst keeps a running spreadsheet of the sewer spills that includes the causes of the spills and the District's management team that consist of the General Manager, Maintenance Supervisor and Engineer along with the field crew use the causes to plan activities, programs and policies to eliminate the causes. The District has identified restaurant grease as the number one cause of sewer line blockages and spills. The District has retained the firm of Environmental Engineering and Contracting (EEC) to manage its FOG program at a yearly cost of $104,000. Approximately five staff members from EEC perform functions in the FOG program including engineers, administrators, and inspectors. In addition to EEC, the District contracts with the Orange County Health Care Agency (OCHCA) to perform a FOG BMP inspection one -time per year at each of the food service establishments (FSEs) inside the District. The cost per inspection is slightly less than $20 per location. These inspections complement the EEC inspections giving the District a two - pronged approach for insuring the FSEs follow the prescribed practices in the FOG notebook developed for each FSE. A. PUBLIC EDUCATION OUTREACH PROGRAM The District's contractor EEC has prepared and distributed a FOG notebook to each FSE inside the District. The notebook includes log sheets for interceptor cleaning, employee education, BMPs, guidelines, and posters. Additionally, the District has made available, on its internet site, educational materials regarding Fats, Oils and Grease (FOG) and the sewer system. The site contains the following five educational materials that can be downloaded by the public: • Keep Fats, Oils, & Grease Out of Your Drain brochure (English & Spanish version) • Homeowner's Guide to Sewer Lateral Maintenance. • Residential FOG Recycling video. • Kitchen Best Management Practices • FAQs about FOG • Grease Interceptor Diagram The District also issues a quarterly newsletter with information regarding keeping Fats, Oils and Grease (FOG) out of the sewer system. In 2011, the District implemented its residential FOG Recycling Program to coincide with traditional holidays (e.g. Thanksgiving, Passover, Christmas, etc.) where residents will be able to properly dispose their grease. Residents can deliver their jug filled grease to the Orange Coast College (OCC) Recycling Center, which is open to the public seven days a week. A contractor will periodically arrive at OCC to remove the grease and W COSTA MESA SANITARY DISTRICT - SSMP 2/25/13 transport it to a recycling facility where it will be recycled for reusable products such as bio -fuel, candles, soap, etc. Over 1,000 gallons of grease has been collected. B. FOG DISPOSAL PLAN The District requires all new commercial construction and existing commercial properties that have been found responsible for previous SSOs to install appropriate grease- reducing devices, including grease interceptors. The interceptors are required to be inspected and pumped out by a licensed company on a regular basis, normally on a quarterly basis. C. LEGAL AUTHORITY TO PROHIBIT DISCHARGES TO THE SYSTEM A permit from the District is required to connect to, use or maintain a connection to the District's facilities (District Operations Code Section 6.04.060 (a)). Any person, firm or corporation that connects or discharges to the District's sewerage system without a valid permit is guilty of a misdemeanor (District Operations Code Section 6.04.060 (f)). The District also has the right to terminate a property from District's service (District Operations Code Section 6.02.080). Every owner, tenant and persons using property shall have a duty not to cause, permit or allow the accumulation of grease in the District's sewer line so that sewage spills may occur. Such persons shall use reasonable methods to reduce grease accumulation in the District's sewer lines including but not limited to reducing or eliminating the grease that is deposited in the sewer and utilizing enzymes and similar products that prevent grease build -up. No person shall discharge grease into the sewer system so as to cause an accumulation in the District's lines so as to substantially contribute to the possibility of a sewage overflow (District Operations Code Section 6.07.040). D. GREASE REMOVAL DEVICE REQUIREMENTS The District's Operation Code requires that all new commercial construction shall have appropriate grease- reducing devices, including sewer interceptors, unless the developer demonstrates, to District Engineer's satisfaction, that such devices are not necessary (Section 6.07.030). The District also requires that no Food Service Establishment shall discharge into the District's system without obtaining a permit from the District describing the business operations and discharge and any FOG prevention measures being undertaken or to be undertaken to reduce the discharge of FOG into the District's system in accordance with this chapter (Section 6.07.050). Furthermore, in cases in which a property is a source of sewer spills on more than one occasion such that recurrence is likely, or in cases in which there is an imminent danger of future sewer spills, the District may order that a property install a sewer interceptor or other appropriate device to protect the District's system (Section 6.07.070). In addition, the Orange County Sanitation District, which is the sewer treatment agency for all the sewage generated within the CMSD boundaries, has adopted Ordinance No. 27 COSTA MESA SANITARY DISTRICT - SSMP 2/25/13 OCSD -25 regarding FOG control which requires the installation of interceptors on all food service establishments, including existing establishments, to install appropriate grease- reducing devices, including sewer interceptors. E. INSPECTION OF GREASE PRODUCING FACILITIES The District has adopted three grease control ordinances, Ordinance 41, in 2003, Ordinance 51, in 2005, and Ordinance 81 in 2010 codified as Section 6.07 of the District's Operations Code, giving the District legal authority to implement a comprehensive grease control program. The District retained Environmental Engineering and Contracting (EEC) to prepare program documents and the Board of Directors adopted these in 2004. The District began its grease control program on January 2, 2005 and has issued a permit to each of the 393 food service establishments inside the District. All 449 food service establishments have been prioritized for inspection with concentration on the heavy grease producing FSEs or those FSEs upstream of hotspots. EEC has produced a GIS map identifying all the FSEs and the hot spots for the Maintenance Supervisor's use in cleaning the system. Notebooks have been distributed to the FSEs and contain posters, BMPs and other materials for reducing grease discharges into the sewer system. Televising the sewer main lines at point of entry of the food service establishment's sewer laterals occurs to gather support evidence for compliance with the grease control ordinances. The follow - up inspections have disclosed a reduction of grease discharged by food service establishments. F. CLEANING SCHEDULE FOR SEWER SYSTEM SECTIONS SUBJECT TO FOG BLOCKAGES The District has identified a number of problem areas that are more prone to blockages and SSOs. These areas are typically inverted sewer siphons and areas with excess grease build -up. These enhanced cleaning areas, or `hot spots', are shown on the GIS map prepared by EEC. G. SOURCE CONTROL MEASURES FOR 'ENHANCED MAINTENANCE AREAS' CMSD and Orange County Sanitation District, which is the sewer treatment agency for all the sewage generated within the CMSD boundaries, have adopted ordinances requiring installation of appropriate grease- reducing devices, including sewer interceptors, on all new commercial developments and existing food service establishments. Furthermore, CMSD has adopted an ordinance allowing the District to require the installation of appropriate grease- reducing devices, including sewer interceptors, on existing properties that are found to be causing or potentially causing SSOs. COSTA MESA SANITARY DISTRICT - SSMP 2/25/13 Additional source control measures for the `Enhanced Maintenance Areas' identified by the District consist of a public education and awareness program that includes distribution of the District's pamphlets for restaurant and homeowner grease control, FOG video on the District's website and a newsletter. The District has also distributed its grease control notebooks to all 449 food service establishments inside the District. The notebook contains a poster, BMP list, and other information relative to the District's grease control program. Since inception of the FOG program, the District has required three FSEs to retroactively install gravity grease interceptors. This was based on the evidence found from CCTV monitoring of the point the sewer lateral enters the sewer main. The FSEs were contributing to a hot spot and were unable to reduce their FOG discharges through BMPs.

The main purpose of a Master Plan is to compare the projected peak flow from the land uses adopted in the General Land Use Plan with the carrying capacity of the sewer lines. New parallel lines or by -pass lines supplement lines identified as unable to handle the maximum flows. The construction of proposed sewer lines is included in the District's capital improvement projects. The Sewer Master Plan was last updated in 2005 and will be next updated when the GIS flow modeling software is installed, which will be approximately in 2013. A. EVALUATION The District's Sewer Master Plan incorporates a hydraulic analysis of the sewer mains in the system. The peak flow estimates are estimated using flow coefficients developed by the District based on land usage. The flow coefficients used by the District have been compared to the coefficients used by Orange County Sanitation District and the City of Los Angeles and found to be reasonable. Special cases, such as high -rise office buildings, hotels and high volume industrial uses are evaluated separately using a peak flow estimate for the individual parcels. The capacity of each line is determined and those lines unable to handle future master planned flows are identified. The current system capacity is able to handle, without surcharge, the current dry weather and wet weather peak sewer flows. I11 l 111 W to @ go IN IWN all /.1 The district has adopted the industry standard of designing new sewer lines up to 18 inches in diameter to be flowing no more than half full at peak wet weather flow. Lines 21 inches or larger are designed to be flowing no more than three quarters full at peak wet weather flow. However, when analysis of existing conditions are completed for the purposes of determining when additional capacity is required, flows above these limits, but less than completely full are accepted. At no time are sewers allowed to flow in a surcharged or pressurized condition. C. CAPACITY ENHANCEMENT MEASURES The District's Sewer Master Plan includes the short and long term CIP to address identified hydraulic deficiencies. Funding for the Capital Improvement Plan is from fees collected from new construction. The District is also active in reducing Inflow and Infiltration (UI). The District has ruled out Infiltration as a source of water in the system but has identified Inflow as a source of water and has begun plugging and sealing manhole covers; particularly manhole covers located in gutters and alley flow lines. The District will be considering completely 30 COSTA MESA SANITARY DISTRICT - SSMP 2/25/13 sealing all manholes in alley flow lines and completely sealing manholes in the vicinity of gutters or curb and gutter. The District is working with the City of Costa Mesa; owners of the local storm drain system, to identify the means by which Inflow enters the system. The District will begin a program to identify illegal connections and the number of backyard swimming pools directly connected to the system. D. CIP SCHEDULE The District's Sewer Master Plan was last updated in 2005 and will be next updated when the GIS flow modeling software is installed, which will be approximately in 2013. 31 COSTA MESA SANITARY DISTRICT - SSMP 2/25/13 IX. MONITORING, MEASUREMENT, AND PROGRAM MODIFICATIONS The SSMP will be reviewed yearly to insure all the provisions are implemented and the effectiveness discussed at a meeting of all field and engineering staff. Updates will occur as appropriate but will occur no longer than once every five years. Performance evaluations are ongoing because the daily operation of the District includes all the elements of the program. District Staff will request the Board of Directors include a yearly or regular appropriation to fund the updating. A recommendation was made to the Board of Directors of the District to consider the Sewer Master Plan Update and its three elements; the Master Plan, the Sewer System Management Plan, and the Emergency Response Program as on -going concerns that will be continually reviewed and updated. X. SSMP PROGRAM AUDITS The District will perform an internal audit evaluating its SSMP and its compliance with the WDR every two years year and will report the results of the audits along with recommendations and suggested improvements to the CMSD Board of Directors. XI. COMMUNICATIONS PROGRAM The District Engineer will provide interested parties with status updates on the implementation of the components of the SSMP and will also consider comments made by interested parties.
