11 T OWN OF H ILLSBOROUGH S ANITARY S EWER M ANAGEMENT P LAN 1. Introduction This chapter of the Town of Hillsborough s (Town) Sanitary Sewer Management Plan describes the Plan s purpose, organization and the regulatory requirements that it satisfies. 1.1 History Public Works (PW) Department staff initiated the SSMP in 2007 in response to Order No DWQ, Statewide General Waste Discharge Requirements for Sanitary Sewer Systems (WDR) and included the Department s routine sewer system collection practices. On October 29, 2013, the San Francisco Bay Regional Water Quality Control Board (RWQCB) visited the Public Works Department to inspect the Town s sanitary sewer collection system. The RWQCB evaluated the Town s compliance with state and legal requirements and provided the Town with recommendations for its response to and reporting of SSOs and for improvements to the Town s SSMP. The Fiscal Year (FY) revisions to the SSMP are robust and comprehensive, and represent the Public Works Department s concerted efforts to improve its maintenance and management of the sewer collection system. Staff reexamined, reevaluated, updated and improved the previous SSMP to best reflect the current Public Works Department organization, its improved practices and the RWQCB s recommendations. The Department is tasked with addressing, implementing and practicing all aspects of the SSMP associated with the operation and maintenance of the sanitary sewer system, emergency response and spill reporting, staff training, mapping, design, system capacity assessment and monitoring of the sewer collection effort as a whole. 1.2 Purpose The purpose of the Town s Sanitary Sewer Management Plan is to describe the Town s efforts and plans to effectively manage its wastewater collection system. Effective management of the Town s collection system includes: Minimizing the frequency and impact of sanitary sewer overflows (SSOs); Effectively and efficiently mitigating the impacts of SSOs should they occur; Providing adequate sewer capacity to convey peak flows; Maintaining and improving the condition of the collection system infrastructure to provide continual reliable service; and Engaging and educating the public regarding programs and issues related to the Town s wastewater collection system. The Town recognizes the importance of preventing sanitary sewage spills to safeguard surface waters, the environment and public health and safety. The Town has updated its Sanitary Sewer Management Plan to ensure continuous improvement of its sanitary sewer system infrastructure and operations, including those related to performance, maintenance, inspection, condition assessment, monitoring, spill response, reporting and identification of repair and replacement needs. The Plan describes the Introduction Page 1

12 T OWN OF H ILLSBOROUGH S ANITARY S EWER M ANAGEMENT P LAN specific activities and procedures the Town s sanitary sewer personnel follow to prevent SSOs and other sanitary sewer performance issues. The Town s SSMP is intended to be updated every 5 years but is designed to be a living document that is continually revised to reflect current changes in sanitary sewer practices, technology, regulation and the Town s collection system. The Town considers its SSMP to be a critical component for short- and longterm planning and budgeting. It also helps ensure that the Town complies with all applicable regional, state and federal sanitary sewer requirements established by the Environmental Protection Agency, the California State Water Resource Control Board, The San Francisco Regional Water Resources Control Board and other regulatory agencies. 1.3 Regulatory Requirements State Water Resource Control Board Order No DWQ The Town s SSMP has been updated in compliance with the State Water Resource Control Board (SWRCB) pursuant to Order No DWQ, Statewide General Waste Discharge Requirements for Sanitary Sewer Systems. The WDR requires all public entities that own or operate a wastewater collection system greater that one mile in length to comply with the elements of the WDR. Noncompliance with the Order constitutes a violation of the California Water Code and is grounds for enforcement action. Generally, the WDR require that: In the event of an SSO, all feasible steps shall be taken to control the released volume and prevent untreated wastewater from entering storm drains and water bodies. If an SSO occurs, it must be reported to the SWRCB using California Integrated Water Quality System (CIWQS), the online reporting system developed by the SWRCB. An SSMP with all mandatory elements be developed and approved by the governing body that owns or is responsible for the operation of the wastewater collection system. The SSMP must include provisions to provide proper and efficient management, operation and maintenance of the sanitary sewer system. A copy of this Order can be found as Appendix A Monitoring and Reporting Program Order EXEC Effective September 9, 2013, Order No DWQ, Statewide General Waste Discharge Requirements for Sanitary Sewer Systems was amended by Monitoring and Reporting Plan (MRP) Order EXEC. This Order replaced earlier monitoring and reporting requirements outlined in MRP Order EXEC. This new order was adopted by the State Water Board to better advance its Sanitary Sewer Overflow Reduction Program objectives, assess Enrollee compliance and enforce WDR requirements. In particular, it: Changes notification requirements for spills that reach surface water; Defines new spill categories and refines spill report fields; Includes additional reporting and water quality monitoring requirements for sanitary sewer spills where 50,000 gallons or greater reach surface waters; and Specifies SSMP electronic submission by Enrollees to the State Water Board. A copy of this order, along with Water Board s Fact Sheet can be found as Appendix B. Introduction Page 2

13 T OWN OF H ILLSBOROUGH S ANITARY S EWER M ANAGEMENT P LAN Additional Regulatory Requirements The following regulatory requirements also establish the need for the Town to maintain and implement a comprehensive SSMP, follow procedures to minimize the potential of SSOs and demonstrate the proper and efficient management, operation and maintenance of its wastewater collection systems. California Water Code Section 13271, California Code of Regulations: Section of the California Water Code, Title 23 of the California Code of Regulations, prohibits the discharge of sewage and hazardous material into the waters of the State and requires the proper notification of authorized agencies in the event of an SSO. Entities which do not properly follow the requirements of this section may be found guilty of a misdemeanor and punished by fine, imprisonment, or both. Clean Water Act, Section 1251 of Chapter 33 of the United States Code: In 1972, the federal Congress enacted the Federal Water Pollution Control Act, commonly known as the Clean Water Act (CWA). The CWA prohibits the discharge of pollutants, including sewage, into public waters of the United States. The federal government has the authority to enforce compliance with the CWA via specific permits, such as National Pollutant Discharge Elimination System (NPDES) permits, as well as court action such as administrative orders and consent decrees. 1.4 SSMP Organization This document begins with this introduction to the SSMP, followed by an overview of Hillsborough and its collection system. The body of the document is organized to discuss the eleven WDR elements in the order that they are presented in SWRCB Order No DWQ, Section D.13: Goals; Organization; Legal Authority; Operation and Maintenance Program; Design and Performance Provisions; Overflow Emergency Response Plan; Fats, Oils, and Grease (FOG) Control Program; System Evaluation and Capacity Assurance Plan; Monitoring, Measurement and Program Modifications; SSMP Program Audits; and Communication. The Plan s Appendix provides documents referenced in the SSMP, arranged by Plan section, in the order that they are first referenced. 1.5 SSMP Plan Certification, Availability and Declaration As required by SWRCB Order No DWQ, Section D.14, the Town s updated SSMP was presented to the Town s City Council for approval at a public meeting on March 11, Additionally, per Section E.14 of the Order, the Town s Public Works Director and City Engineer has completed the Introduction Page 3

Sanitary Sewer Service Area and Collection System Overview 2.1 Service Area The Town of Hillsborough (Town) is a residential community located in San Mateo County, California. It is west of Highway 101 and El Camino Real and east of Highway 280 within a short commute to San Francisco and minutes from the San Francisco International Airport. Figure 1: Map of Town of Hillsborough The Town has a total area of 6.23 square miles and a population of approximately 10,850. Hillsborough is a single family residential community with just five commercial businesses (three private schools, one racket club and a private golf course). The Town is, by and large, fully developed and built-out. Hillsborough enjoys a mild, Mediterranean climate with temperatures that vary from a mean average of 50 degrees Fahrenheit in January to a mean average of 72 degrees Fahrenheit in July and a mean annual rainfall of approximately 23 inches. Sanitary Sewer Service Area and Collection System Overview Page 5

16 T OWN OF H ILLSBOROUGH S ANITARY S EWER M ANAGEMENT P LAN 2.2 Sanitary Sewer System The Town s sanitary sewer system is managed by the Town s Public Works Department, Street and Sewer Division. The Division organizes its sanitary sewer system into sewer basins. The system is comprised of a collection system and sanitary sewer pump stations Sanitary Sewer Basins The Town s sanitary sewer system consists of two primary sewer drainage basins: the Burlingame Sewer Basin and the San Mateo Sewer Basin. Wastewater from the Town s Burlingame Basin flows north into Burlingame s wastewater treatment plant. Wastewater from the San Mateo Basin flows south into San Mateo wastewater treatment plant. The Town has approximately 3,915 sewer accounts. Of these 3,915 accounts, 1,800 (46%) are in the Burlingame Sewer Basin and 2,115 (54%) are in the San Mateo Sewer Basin. Sanitary Sewer Service Area and Collection System Overview Page 6

17 T OWN OF H ILLSBOROUGH S ANITARY S EWER M ANAGEMENT P LAN Figure 2: Map of Wastewater Basins The Town has divided its two sewer drainage basins into 108 mini-basins that identify small areas of the collection system that can be efficiently and effectively cleaned within a few days. The effectiveness of this approach is further discussed in Element 4, Operations and Maintenance Sanitary Sewer Collection System Hillsborough s sanitary sewer system is comprised of 98 miles of collection system mainlines, 2,565 manholes, and 4 sewer pump stations. Pipe sizes range from four to twenty-eight inches in diameter and are predominately made of vitrified clay pipe. Nearly two-thirds of the Town s collection system was built before Forty-two percent of the Town s collection system lies in easement areas.

Approximately one-half mile of the collection system is comprised of forced mains. These forced main areas are serviced by four sanitary sewer pump stations located in two locations: Central Hillsborough: Hayne and La Honda lift pump stations. Southern Hillsborough: Brooke Court and Sugar Hills lift pump stations. Sanitary Sewer Service Area and Collection System Overview Page 8

19 T OWN OF H ILLSBOROUGH S ANITARY S EWER M ANAGEMENT P LAN The pump stations were constructed between 1976 and 2002 and have varying flows. The lift stations are located in areas that allow them to assist in the conveyance of wastewater to a gravity point from which it flows downhill to either the San Mateo or Burlingame treatment plants. All four pump stations have pumps that automatically alternate and adjust based on flow. Wet well operations are set to limit pump starts and stops and in-line storage of wet weather flows occurs automatically. Power outages occur infrequently and average about eight a year. Each pump location has a backup generator that is monitored by the Town s SCADA system 24 hours a day. In addition to the four pump stations, the Town also owns and maintains two sewer ejector systems located at the Hillsborough Police Station and the Public Works Corporation Yard. Both of the sewer ejectors are for single facilities and are managed and maintained in the same manner as the sewer pump stations. Public Works may eventually take both small sewer ejectors out of service during a planned future renovation and gravity feed the associated systems.

Element 1: Goals and Objectives This chapter describes the goals and objectives that the Town has established to properly maintain and operate its sanitary sewer collection system. The goals represent the Town s overall vision and the objectives provide specifics on the attainment of its goals. The sanitary system maintenance goals and objectives have been or will be adopted into the Town s Annual Budget. 3.1 Goals The Town s goals for operating and maintaining its sanitary sewer system align with those identified in the WDR: Properly manage, operate, maintain and improve all parts of its wastewater system; Provide adequate capacity to convey peak flows; Minimize the frequency and volume of SSOs; Mitigate the impacts of SSOs if they occur; and Ensure the safety of Town employees, residents and the public at large. SSD crews conduct daily preventative maintenance and rapid response to prevent, contain and mitigate SSOs. The SSD works regularly with Engineering Division and Public Works (PW) managers to identify sanitary system structural issues in order to improve the condition and extend the life of the Town s collection system over time. 3.2 Objectives The Town s objectives for operating and maintaining its sanitary sewer system are measured annually as key performance indicators: Measurably increase preventative maintenance on the collection system to decrease SSOs. Conduct 53,000 linear feet of video condition assessment each year and conduct a complete video assessment of the entire sewer system every ten years (more frequently for problem areas). Pre-schedule and conduct monthly, quarterly, bi-annual, annual and as needed preventative hydro-jet and power-rod maintenance, progressing methodically through approximately twothirds of the Town s sewer basins annually and the entire system every 18 months. Conduct root control foaming on approximately 80,000 linear feet of identified root control areas each fiscal year on a 2 year rotating basis for a total of 160,000 linear feet every two years. Conduct annual FOG outreach program targeting all schools, the country club and the year s identified hotspots and provide information to residents via website and newsletter. Conduct annual analysis of SSOs, repeat non-scheduled maintenance and other maintenance activity data captured in Lucity, the Town s computerized maintenance management system, to Element 1: Goals and Objectives Page 11

22 T OWN OF H ILLSBOROUGH S ANITARY S EWER M ANAGEMENT P LAN identify and refer potential problem areas to Engineering for structural improvement consideration. Annually evaluate the funding needs to operate and maintain the sanitary sewer system using the most up-to-date Sewer Utility Cost-of-Service Independent Rate Study. Annually review the priority of projects in the adopted 5-year Capital Improvement Project (CIP) budget to address and prioritize the most critical maintenance needs. Include lateral launching (video of lateral) during main line inspections, where possible. Substantially decrease down-time of sanitary sewer pumps by operating all pump stations at peak efficiency and performing regularly scheduled inspections and preventative maintenance on equipment at all sanitary sewer pump stations. Provide bi-monthly operational training to improve operational efficiencies and performance. Provide annual SSMP training and a minimum of 12 classroom hours per 24 month period for each SSD employee. Reflect key maintenance and operation changes in the SSMP each year, conduct an SSMP audit every 2 years and complete a thorough SSMP update every 5 years, as necessary.

Element 2: Organization, Communication and Reporting This chapter provides the Town s organizational chart and identifies the agency staff responsible for implementing, managing and updating the SSMP and the chain of communication for responding to and reporting SSOs Reorganization The purpose of this section is to explain the reorganization of the Public Works Department in Fiscal Year The Town reorganized its Public Works Department in order to strengthen the SSD and its ability to prevent and respond to SSOs. In 2011, there were several contracted Public Works positions and the Town s Engineering Division was entirely composed of contracted staff. Additionally, the Sewer and Streets Divisions were managed separately. In Fiscal Year , the Public Works Department was re-organized. Key contract staff positions were converted to in-house staff positions. A Public Works Superintendent position was also added in 2012 in order to streamline communication between field operations and engineering and to assist with sewer maintenance and capital improvement projects. Additionally, the Sewer Division and Streets Division were combined into one division to allow for more staff to be available for sewer operations and maintenance Organization The following section provides an organizational chart for the Public Works Department. The chart provides the names for management, administrative and maintenance positions responsible for implementing specific measures in the SSMP. All Public Works staff can be reached via the Public Works main telephone line (650) A brief description of key positions as they relate to the SSMP follows the organizational chart.

The Town s sanitary system overflow detection, notification, response and reporting process is briefly discussed in Element 6 of this SSMP and is fully described in the Town s Sanitary Sewer Overflow Emergency Response Plan, which is provided as Appendix D. SSOs may be discovered and/or reported by the general public, a Town contractor or Town staff. In all cases, SSOs can be immediately reported by calling (650) during business hours or (650) after hours. Additionally, all Town Department administration desks and Public Works Department staff have access to hand-held radios for reporting and dispatching purposes Normal Hours Normal hours for the Town s Public Works Department are Monday through Thursday, 7 a.m. to 5 p.m. and Fridays 7:30 a.m. to 4:30 p.m. When a report of a sewer spill or backup is made by the public during normal work hours, Public Works administrative staff receives the call, dispatches the Sewer Department s nearest crew and starts a Sewer Request Form in Lucity. The Sewer Supervisor is also notified and contacts the customer and completes the Sewer Request Form. Element 2: Organization, Communication and Reporting Page 16

27 T OWN OF H ILLSBOROUGH S ANITARY S EWER M ANAGEMENT P LAN After Hours After hours service calls are received by Hillsborough Police Department s Non-Emergency Dispatcher who then notifies the Public Work s On-Call Employee. The On-Call Employee responds and initiates the reporting and tracking documentation by entering the information into Lucity. The information is put into a custom SSO spill report form, which associates the information with a point on the Geographical Information System (GIS) map. The on-call staff also fills out hard copy field reports in the field, which are attached to the electronic file. In all cases, one or more first responders arrive and assess the situation. If the event is an SSO, the responder(s) calls the Sewer Supervisor and Public Work Superintendent. The most senior SSO First Responder available is responsible for directing the initial sewer response crew and support standby crew through the entire SSO event from mitigation, cause removal, clean-up and follow-up closed circuit television (CCTV). The SSO First Responder is also responsible for ensuring proper event documentation and photographs, timely reporting to appropriate agencies and arranging for the collection of water samples as necessary. After the event, the SSO First Responder is responsible for communicating the details of the event to management, ensuring that all necessary paperwork is completed in full.

Title 13 Public Service, Division III. Sewage and Sewers: This Title contains four chapters dedicated to the construction and maintenance of the Town s sewer system: Chapter Construction and Maintenance: The purpose of this chapter is to provide the requirements for sewer system permits, inspections, bonds (for work in easements) and conformance to the California Plumbing Code and the Town of Hillsborough Standard Details. It prohibits stormwater from wastewater conveyance systems, describes appropriate wastewater connections and fees, confers responsibility of private sewer lateral responsibility to the private property owner and requires the improvement of sewer laterals upon new construction, significant remodel and/or parcel subdivision. Finally, it requires the repair/replacement of the connecting sewer main upon abandonment of a private lateral line. Chapter Private Sewer Laterals: The purpose of this chapter is to establish responsibilities and requirements of the Town and individual property owners for the inspection and repair of private sewer laterals, which are determined to be causing or contributing to sanitary sewer overflows. It describes the steps the Town will be taking to reduce or eliminate infiltration and inflow coming from defective laterals. It also describes incentives that will be offered by the Town to encourage homeowners to rehabilitate their sewer laterals, and it revises the Hillsborough Municipal Code as necessary to clarify what will be required when homeowners or private contractors do sewer lateral rehabilitation work. Chapter Sewer Service Charges: The purpose of this chapter is to set forth the sewer service charges and related provisions to meet the expenses of the Town s Sewer Division and its contractual obligations with respect to its sewer treatment agreements. Chapter Prohibited Connections: The purpose of this chapter is to prohibit the discharge of stormwater and non-sewage wastewater into the Town s sewer system and provide for the inspection, abatement and penalization of said discharges. Chapter Plumbing Code: The purpose of this chapter is to regulate the installation, repair and maintenance of all plumbing fixtures, appliances and systems (including, but not limited to, water supply, domestic water piping, sanitary drains, wastes, vents and drainage of other concentrations of water or wastes), swimming pools, spas and hot tubs, including design and materials, and to provide for inspections, violations, and adopting uniform rules, regulations and standards in respect thereto. Chapter Public Improvement Standards: The purpose of this chapter is to establish standards for the design and improvement of private developments and the acceptance, dedication and improvements of public lands.

Element 4: Operation and Maintenance Program This chapter provides a detailed description of the Town s effective management, operation, maintenance, inspection, repair, replacement and funding of its sanitary sewer collection system and is comprised of the following sections: Information Management and Mapping Prioritized Preventative Maintenance Inspections and Condition Assessment Repairs Resources and Budget Equipment and Inventories Training Outreach to Plumbers and Contractors 6.1 Collection System Information Management and Mapping This section describes Hillsborough s sanitary sewer mapping systems and the steps in place to keep map related data updated. Hillsborough maintains geographically based datasets on of all its wastewater assets, including: Gravity and Force Mains; Manholes; Pump Stations; Laterals; Meters; and Other Sewer Assets. Hillsborough effectively manages and maintains geographically based asset and attribute data in order to render detailed maps of its sanitary sewer systems using the following software: Automated Computer Assisted Drafting (AutoCAD); Geographical Information System (GIS); Global Positioning System (GPS); Computerized Maintenance Management System (CMMS); Community Development Software (CRW); Element 4: Operation and Maintenance Program Page 29

40 T OWN OF H ILLSBOROUGH S ANITARY S EWER M ANAGEMENT P LAN Supervisory Control and Data Acquisition (SCADA); and Smart Manhole Covers. The Town uses the above software and associated hardware to provide electronic and hard copy maps for its field and office employees. The following briefly describes Hillsborough s use of this software Automated Computer Assisted Drafting AutoCAD is a software application for 2D and 3D computer-aided design and drafting. It is used by Hillsborough and its design contractors/consultants for sewer system construction design work. Pertinent data regarding sanitary sewer collection system projects designed/created in AutoCAD, and in particular information pertaining to sewer asset features (e.g., manhole number, mainline size and length), are imported into ArcESRI upon project construction/ completion. The Engineering Division developed a set of AutoCAD standards to ensure that all plan information, whether developed by the Town, consultants or private owners, can be seamlessly brought into the Town s GIS system Geographical Information System The Town uses ArcMap 10.2 to capture, store, manipulate, analyze, manage and present geographical data for all of the Town s utility assets, including all sanitary sewer assets. GIS also stores and manages certain static attribute classes (e.g., size, material type) associated with its utility assets. Non-static attribute classes, such as maintenance records, are stored and managed in the Town s CMMS system. The following table provides examples of sewer asset and attribute data stored, managed and maintained in GIS.

All Town employees have read-only access to Element 4: Operation and Maintenance Program Page 30

41 T OWN OF H ILLSBOROUGH S ANITARY S EWER M ANAGEMENT P LAN GIS via a user friendly and robust GIS web portal. Town employees use the GIS portal to access and manipulate (turn on/off) utility asset data layers, locate assets, view asset attributes, print maps and conduct other non-administrator level uses of the available data. The Town has a process for Town employees to correct/update GIS data as changes are identified or improvements are made to the system. The Town has integrated its GIS, CMMS, CRW and handheld GPS systems. The advantages of this integration to field, management and administrative staff and efficient sewer operations are described below Global Positioning Systems The Town owns several types of GPS enabled devices for use by field and management employees: Handheld GPS: The Town owns a Trimble GeoXH GeoExplorer 6000 Series, with a Trimble Tornado external GPS antenna. This is a professional grade GPS hand-held unit with sub-footage accuracy and post-processing software. It is integrated with the Town s GIS and is capable of importing and storing Town GIS data, assets and attributes. The device can also be used as a camera (photos are attached to GPS points). Computer Tablets: The Town recently purchased several computer tablets of varying sizes, types and capabilities. The Town is testing its newly implemented CMMS software on these tablets and will purchase additional computer tablets once testing is completed. The tablets are GPS enabled and can be useful when the handheld GPS is not available and sub-footage GPS accuracy is not necessary. The units can also be used to take photos and videos of assets and field conditions as necessary. Sanitary and Street Division Supervisors, Lead Workers and Inspectors will eventually have access to a computer tablet for field use. Smart Phones: The Town provides all field employees with smart phones. Smart phones are GPS enabled and can take photos and videos as well. Smart phones can be used to locate assets when GPS accuracy is not of critical concern. Town employees are trained to use the Trimble GPS or GPS enabled devices to quickly find utility assets in the field and accurately geo-locate assets that are mis-mapped in the Town s GIS database. The use of the Town s GPS devices is especially critical in finding sanitary sewer assets in heavily vegetated and sometimes difficult to access easement and open space areas. These devices, and the data that can be collected by them, can substantially improve employee response time and performance during critical events such as SSOs Computerized Maintenance Management System The Public Works Department is implementing a CMMS program, called Lucity ( to plan, assign, record, manage and report on its day-to-day operations for all its Divisions, including the SSD. Lucity is fully integrated with the Town s GIS and allows the Public Works Department and its Divisions to: Schedule preventative maintenance and inspections based on priority, geographical location, route, equipment and personnel needs and other considerations; Quickly locate, identify and access information on all utility assets; Manage work orders and associate them to GIS-based assets in order to track and analyze maintenance history; Use maintenance history to identify problematic assets for possible repair/replacement (CIP); Element 4: Operation and Maintenance Program Page 31

42 T OWN OF H ILLSBOROUGH S ANITARY S EWER M ANAGEMENT P LAN Access documents, pictures and videos on mobile computing devices in the field in real time; and Create and run reports for regulatory compliance, budgeting, management and to identify potential improvements in operational efficiency. Figure 15: Lucity Software System The SSD used a different third-party CMMS software solution than Lucity from 2006 through On November 15, 2013, the Town transferred all CMMS data from its former CMMS software into Lucity. Since that time, all SSD work orders, inspections and other work activities are managed by and saved in Lucity. Further, the SSD has scheduled all preventative maintenance in Lucity. (Preventative maintenance is further discussed later in this chapter). Lucity is a powerful work planning, resource management, work order management, record keeping and GIS enabled software that provides SSD field employees, supervisors and managers the tools necessary to effectively manage collection system operations and maintenance. It is also a powerful report and analytical tool with fully customizable queries and reports that provide supervisors and managers the ability to analyze historical performance to find opportunities for work efficiency and improvement. Sewer crews are assigned weekly assignments utilizing the electronic work order process in Lucity. The work order process allows staff and supervisors to manage their workload on an hourly, daily, weekly and monthly basis, and track maintenance activities on Town assets. The SSD is currently using printed work orders and maps during the Lucity implementation and testing stage. Printed work orders are completed in the field, entered into Lucity and then filed. Printed copies of work orders ensure that there is a backup of all completed work in the event of unforeseen software issues or implementation bugs. The Town will eventually phase out paper work orders in favor of electronic work orders. Electronic work orders will be managed on computer tablets connected to Town servers via cell phone Element 4: Operation and Maintenance Program Page 32

43 T OWN OF H ILLSBOROUGH S ANITARY S EWER M ANAGEMENT P LAN or wireless signals. This will enable field employees to receive, view, manage, complete and transmit work orders in real time. They will also be able to receive and/or view in the field photos, maintenance manuals and other documents associated with sewer assets of concern. The Town s use of Lucity is intended to help maintenance workers do their jobs more effectively and efficiently Community Development Software The Town uses community development software called CRW ( to permit, manage inspections of, regulate land use for and track construction and development projects. CRW is integrated with the Town s GIS system. The SSD supervisors and inspectors use CRW to monitor and track both CIP and private sewer construction projects. Projects and inspections are tracked and managed utilizing CRW s Trakit tool. This software tracks permit issuance, responsible parties, plan checking, correction notices, special conditions, submittals, products and materials and inspections. The Building Department also uses CRW to monitor, track and coordinate efforts with Public Works. CRW provides non-town employees (e.g., residents, contractors, architects, developers) the opportunity to view project permit and status updates in real time. It also allows the exchange of electronic forms, plans and permits between the Town and the construction project team. This software is utilized in addition to the Town s CMMS program Lucity. Figure 16: CRW Software Supervisory Control and Data Acquisition The Town s Supervisory Control and Data Acquisition System (SCADA) was updated in March 2012 and provides 24/7 operation monitoring and notification for all four sewer pump stations and the two sewer ejector pumps. SCADA also provides 24/7 immediate text notification to management, supervisors, key Element 4: Operation and Maintenance Program Page 33

44 T OWN OF H ILLSBOROUGH S ANITARY S EWER M ANAGEMENT P LAN staff, standby personnel and on-call staff in the event of a system malfunction or high flow issue. The SCADA software also provides monitoring, management, trend, tracking and reporting tools and capabilities. Figure 17: SCADA System Smart Manhole Covers The Town invested in its smart manhole cover system in Smart manhole covers provide a 24/7 early warning flow monitoring system. The smart covers are installed in seventeen locations throughout the Town s service area. These locations were chosen based on historic problematic issues or close proximities to hotspots. The smart cover electronic sensors can be relocated as needed to other high priority locations. The smart cover software provides 24/7 immediate text notifications to management, supervisors, key staff, standby personnel and on-call staff. The software also provides monitoring, management, trends, tracking and reporting tools. Figure 18: Smart Manhole Cover Locations Element 4: Operation and Maintenance Program Page 34

45 T OWN OF H ILLSBOROUGH S ANITARY S EWER M ANAGEMENT P LAN The primary function of the smart cover system is the prevention of SSOs. Through the advanced alarming and notification capabilities of the smart cover system, key Town staff has the ability to dispatch crews to resolve blockages within the collection system prior to an SSO occurring. The second major function of the smart cover system is data collection and logging to provide staff with hydraulic level information pertaining to the Hillsborough collections system at locations where the smart covers are installed. The Town s smart covers are connected with the Town s SCADA system. Figure 19: Smart Manhole Cover System Communication Diagram Maps and Map Books The Town has historically provided printed map books to its field maintenance workers and supervisors. Map books are hard-bound sets of over 180 map tiles that display parcels and street information along with sewer, storm, water and facility assets. They are printed as needed and are referenced by field staff to find and identify sewer assets and to plan and manage maintenance and operational activities. For example, sanitary sewer crews may use their map book to find sanitary sewer manholes in easement areas or to determine where to block storm drainage networks in the event of a sewage spill. The Town recently procured a 42 wide plotter/printer to print wall-sized map sheets, and contracts with print vendors to print larger scale maps as needed. These maps are wall mounted in the Town s Emergency Operations Center (EOC) and Training Room and are used to inform in-office operations and maintenance planning meetings and discussions. The EOC also has a 54 flat-panel, touch screen monitor on which GIS can be displayed. The Town has several other large, flat screen monitors in the Superintendent and Town Hall meeting rooms on which maps can also be displayed in detail. Wall maps of the Town s utility systems can also be found in the Superintendent, Supervisor and Main Office areas. Additionally, access by SSD field employees and supervisors to Lucity via computer tablets in the field will provide them with full GIS map functionality and access to real-time geo-location of all Town utility assets and associated inspections and work histories. The purpose of maintaining these systems and map books is to provide all SSD employees with accurate and up-to-date, geographically based sanitary sewer system information in the office and field environments. Element 4: Operation and Maintenance Program Page 35

46 T OWN OF H ILLSBOROUGH S ANITARY S EWER M ANAGEMENT P LAN Figure 20: Map Book Information and Map Maintenance The Town maintains mapping system information via the following methods: 1. Daily updates via field observations/surveys; 2. CCTV; 3. Inspections and Condition Assessment; and 4. Capital Improvement, Development Projects, As Build Drawings Field Observations Field employees sometimes encounter discrepancies and errors in the location of assets in current maps. Employees take the following steps to correct mapping errors: Accurately locate asset; Submit geo-coordinates or map-redline to Engineering (either in writing on a printed map or electronically using Lucity s red-line function); Engineering verifies correction against GIS data, construction plans and other sources; Engineering accurately (re)locates asset in GIS; GIS corrections are auto-updated in Lucity on a weekly basis for immediate reference; and Map books are updated quarterly or more frequently if needed. Element 4: Operation and Maintenance Program Page 36

47 T OWN OF H ILLSBOROUGH S ANITARY S EWER M ANAGEMENT P LAN CCTV The Town utilizes CCTV to identify defects, confirm sewer lengths and configurations of the sanitary sewer system. The Town requires contractors to CCTV pre- and post-construction. The Town s required rating system is consistent with the National Association of Sewer Service Companies (NASSCO) Pipeline Assessment and Certification Program standards. Individual pipe segments are video inspected and pipes with deficiencies assessed and graded. This new information is then verified by staff to insure that deficiencies and pipe configurations are accurately reflected in the Town s GIS. Inspections and Condition Assessments The Town also updates GIS information during inspection and condition assessment projects. For example, in 2011 the Town implemented a manhole inspection project. All data collected during the project inspections (such as manhole component materials, sizes, condition, etc.) were captured in a GIS layer. Capital Improvement and Development Projects AutoCAD drawings and datasets for all capital improvement, development projects and as-built drawings are sent to the Engineering Division as part of project close-out. Engineering uses this information to update the Town s GIS. 6.2 Prioritized Preventative Maintenance Goals and Objectives The Town uses its information management and mapping tools and data, along with field knowledge and experience, to plan, prioritize, schedule and document preventative maintenance on all its sanitary sewer assets in order to reduce SSOs. The Town s collection system needs frequent maintenance due to the age, material and makeup of its system. The overarching goal of the Town s prioritized preventative maintenance program is to prevent SSOs, sewer issues and customer complaints, and to respond quickly to and contain them when they occur. The objectives of the preventative maintenance program include: Decrease the volume and number of SSOs through on-going and targeted prioritized preventative maintenance. Clean all 98 miles of Town sewer mainlines within the identified required maintenance period of 18 months and document issues; Continue with monthly, quarterly and bi-annual cleaning of all identified sewer main hot-spots. Conduct a video condition assessment of all 98 miles of sewer mainline every ten years and more frequently for problematic areas. Root-foam approximately 80,000 linear feet of sewer mains every year and repeat foaming on said root-foamed lines every two years. Replace or repair all sewer lines with grade 5 defects immediately if failure is likely or has occurred, and within 2 years if immediate failure is not likely. Replace or repair all sewer lines with grade 4 defects within five years of discovery. Visually inspect all 2,750 manholes every three years. Element 4: Operation and Maintenance Program Page 37

48 T OWN OF H ILLSBOROUGH S ANITARY S EWER M ANAGEMENT P LAN Refer mainlines with repeat non-scheduled maintenance to sewer engineering for evaluation. Conduct appropriate analysis/evaluation of SSOs utilizing historical maintenance and activity data and records and provide recommendations to reduce future risk. The Town s sanitary sewer assets that have prioritized preventative maintenance scheduled in the Town s Lucity system are: Sanitary Sewer Gravity and Forced Mains; Manholes; Sanitary Sewer Pump Stations; Sanitary Sewer Pump Station Generators; and Other Sewer Assets Sanitary Sewer Preventative Maintenance The Town has created a prioritized preventative maintenance schedule to clean all 98 miles of sewer mains at least once every 18 months. In order to schedule and execute this effectively, Hillsborough used GIS to divide its sanitary sewer collection system into 12 major sewer basins that logically group the convergence of pipe networks into one point of flow into a single trunk line. These 12 major sewer basins were further divided into 108 mini basins that represent cleaning areas. The 108 mini-basins are logical boundaries that identify small areas of the collection system that can be efficiently and effectively cleaned within a few days. Hillsborough uses these mini-basins to schedule preventative maintenance work orders in Lucity. The preventative maintenance schedules entered into Lucity are based on the asset type, maintenance activity, frequency, priority, equipment needs and employee requirements. The schedule strategically and systematically moves from North to South through the entire sewer conveyance system over an 18 month period. The PM cleaning schedule is designed to coordinate several maintenance crews and cleaning methods within the same area so that they can support each other and still be flexible enough to respond to as-needed maintenance activity. The work orders follow sanitary sewer flows so that crews work from upstream to downstream as mainlines converge into trunk lines. Figure 21 provides a map of the 108 mini-basins. Element 4: Operation and Maintenance Program Page 38

49 T OWN OF H ILLSBOROUGH S ANITARY S EWER M ANAGEMENT P LAN Figure 21: Map of Hillsborough Sewer Mini-Basins Hillsborough performs a number of preventative maintenance activities on its system, including root foaming, hydro-jetting, power- and hand-rodding and pump station maintenance. As mentioned, the Town has scheduled all of these preventative maintenance activities in Lucity. Following is a preventative maintenance schedule for each preventative maintenance activity. The table shows the number of months it will take SSD crews to complete the maintenance task at least once for all applicable assets in the Town. For example, SSD crews will hydro-jet flush all accessible sewer main lines at least once every 18 months. Element 4: Operation and Maintenance Program Page 39

The Town conducts root foaming operations in each of these basins independently. The Town conducts 93,000 linear feet of root foaming in the Burlingame basin and conducts 73,000 linear feet of root foaming in the San Mateo basin. The Town plans to conduct Burlingame basin root foaming operations in May/June every even year and in July/August every odd year. In each case, the Town is scheduled to hydro-jet all root-foam treated lines approximately six weeks after treatment. The areas targeted for root foaming within each basin were identified based on data received from the past maintenance work records, CCTV inspections and visual inspections. SSD will adjust root-foaming routes and areas based on future findings and assessments. The use of two contracts in two separate basins within Hillsborough will allow the Town to manage root foaming activities more efficiently. Additionally, the SSD crews conduct as needed root-foaming. The Town notifies its downstream WTPs of all root-foaming activities. Hydro-Jetting The Town uses the hydro-jet equipment to clear large sewer mains of roots, FOG and other debris. At the time of writing, the Town owns two large vactor jet trucks for cleaning large and easily accessed sewer mains and is procuring a mini hydro-jetter in order to better clean easement lines located in open space and difficult to reach easement areas. Difficult to access lines are typically/currently cleaned using hand-rodding. Hand-rodding is difficult and time consuming work. The Town s goal is to improve operator efficiency and safety by replacing the hand-rodding activities whenever feasible with minijetting. The Town has annual preventative maintenance hydro-jetting scheduled in Lucity. The Town also performs as needed hydro-jetting when responding to reported or discovered issues. Power- and Hand Rodding The Town uses power-rodding and hand-rodding equipment to clear sewer main lines of roots and debris. The power-rodder is used when there is reasonable access and the need to cut through heavy root intrusion or debris. The hand-rodder is used when access is an issue for the power-rodder. The hand-rodder will be phased out in preference of mini-hydro-jetter, where practical. The Town has annual power-and hand-rodding preventative maintenance scheduled in Lucity each year. Element 4: Operation and Maintenance Program Page 40

51 T OWN OF H ILLSBOROUGH S ANITARY S EWER M ANAGEMENT P LAN Pump Stations The objective of the pump station maintenance and inspection program is to ensure that the Town s four sewer pump stations operate as designed and at peak efficiency, particularly during heavy wet weather flows. The Town supplements regular SSD staff pump station inspection and maintenance with periodic services from professional contractors. The Town contracts with specialty contractors for pump repairs, generator service and electrical work to assist in the maintenance and inspection of the Town s sewer pump stations. All four sewer pump stations have pumps that alternate automatically. None of the stations have lead/lag pumps. Wet well operations are set to limit pump starts and stops, and in-line storage of wet weather flows occurs automatically. Power outages occur infrequently and average about eight per year. The Town has backup generators at each site. The generators are exercised under load on a set schedule. In addition the Town has two portable generators that are shared between the Water and Sewer and Street Divisions, as needed. Inspection Process Sewer pump stations are inspected weekly, monthly, quarterly and annually. Records of these inspections are maintained in Lucity. Maintenance records are referenced by management, operations and maintenance crews to ensure established procedures are being followed to ensure maximum reliability. Following is a description of sewer pump station inspections and maintenance, by frequency: Weekly Inspections: Meter reading; Inspect wet well for general appearance and excessive grease buildup on surface, clean when needed; Clean up trash or debris material, including in the sump pump area of station; Run each pump by hand/manual control and watch level control go up and down to ensure pumps are operating properly; Place pump controls back in auto position prior to leaving station; Visually inspect emergency generator for fuel and ability to operate properly; Test all panel lights and change as needed to ensure proper operation; Complete all required paper work; and Lock up station, reset entry alarm close all panels prior to leaving. Monthly Inspections: Open up wet well and visually inspect the pumping of each pump; Completely pump down the wet well to its lowest point and make a visual inspection; Hose the wet well down during the pump down process; Check wet well floats (if applicable) for grease build up, clean as needed; Run the power backup generator and check the fuel level, battery and general condition; and Turn in operation log sheets at the end of the month. Element 4: Operation and Maintenance Program Page 41

52 T OWN OF H ILLSBOROUGH S ANITARY S EWER M ANAGEMENT P LAN Quarterly Inspections: Use the vacuum truck to clean grease and grit from the wet well; and Operate generator under load for 15 minutes (This test is to be conducted by tripping power to the station and observing a successful transfer to generator power. Emergency generators are to be operated per manufacture s requirements and in compliance with any City, County, or State agency operating permit.) Bi-Annual Inspection: Inspect impeller and ensure that it is free of debris. Annual Inspections: Pump out and clean wet wells at least once a year, or more often if necessary, to prevent solids and grease build-up, which can create odors and damage to the pump; Inspect check valves to ensure proper working order and to prevent backflow from the force main to the wet well; Inspect and clean floats to assure proper performance; Inspect and test light and alarm systems; and Test the emergency backup generator by operating the units under load per operating permit requirements and visually check fuel level, battery and general condition. Additionally, the pumps and pump facilities receive annual inspection and maintenance from third-party pump maintenance and electrical contractors.

Where appropriate, the crew forwards to the Engineering Division recommendations for major rehabilitation or formal engineering inspection of specific stations as a standard part of the preventative maintenance program. Additionally, the SSD utilizes a SCADA system to monitor pump run-times. SCADA is set to send alarms to SSD staff via text and . The alarms include, but are not limited to, high and low-wet well levels, pump overload, dry pit flooding and power failure alarms. Element 4: Operation and Maintenance Program Page 42

53 T OWN OF H ILLSBOROUGH S ANITARY S EWER M ANAGEMENT P LAN Preventative Maintenance Evaluation and Performance Indicators The SSD meets quarterly to: Evaluate the effectiveness of certain types of cleanings and inspections; Evaluate trend screens from SCADA and Smart Cover System; Discuss whether the frequency of cleaning is appropriate at each location; and Identify if other problem areas have surfaced that should be added to the PM list. Preventative maintenance schedules in Lucity are adjusted based on the findings of these quarterly meetings. 6.3 Scheduled Inspections and Condition Assessments The Town s inspections and condition assessment efforts are closely integrated into the preventative maintenance program described above. The Town uses inspections and condition assessments to proactively identify and prioritize structural deficiencies and implement short and long term prioritized actions to address discovered deficiencies. The Town s monitoring and inspection program is designed to prevent excessive inflow/infiltration, service interruptions and system failures that could result in SSOs. Problem areas are identified using a variety of tools, including visual inspection, video inspection, smoke testing, flow meters, SCADA and smart manhole covers. Inspections are pre-scheduled in Lucity for all sewer collection mains and assets CCTV The Town video assessed its entire sanitary sewer collection between 2008 and The assessment assigned every sanitary sewer segment a condition assessment of 1 (excellent) through 5 (critical failure). The Town used the assessment results to create a repair and replacement schedule for all category 4 and 5 segments and place critical through moderate condition lines on a regular preventative maintenance schedule (until such time as the lines are repaired/replaced). The Town has since created a preventative maintenance schedule in Lucity to conduct video condition assessment of all 98 miles of sewer mainline every ten years and more frequently for problematic areas. The Town s rating system is consistent with the NASSCO Pipeline Assessment and Certification Program standards. Individual pipe segments are video inspected and deficiencies assessed and graded. This new information is then verified by staff to insure that deficiencies and pipe configurations are accurately reflected in the Town s GIS. CCTV video is maintained on the Town s server, linked to the appropriate pipe asset and is readily available to office and field staff via Lucity Sewer Manhole Inspections and Maintenance From , The Department conducted a Manhole Assessment Condition Program (MACP) in which 2,750 manholes were inspected. The inspections were comprised of visual inspection and assessment to grade the condition of the manhole from 1 to 5, per NASCO standards. The program was designed to prevent I/I. All data collected during the inspection (such as manhole component materials, sizes, condition, etc.) was captured in GIS. The Town has an ongoing MACP program in which it visually inspects 2,750 manholes every 3 years. The manhole inspections are scheduled in Lucity. Element 4: Operation and Maintenance Program Page 43

54 T OWN OF H ILLSBOROUGH S ANITARY S EWER M ANAGEMENT P LAN Smoke Testing The Town conducted a 2012 Smoke Testing project completed in the Burlingame (North) sewershed wastewater collection system. The associated report provided recommendations to address infiltration/ inflow deficiencies. Collection system field inspections included mainline and private service lateral smoke testing and private sewer lateral closed circuit television inspections. Inspections were performed to identify and document public and private I/I defects. The table below provides an overview of the smoke testing conducted.

The most common public-sector smoke source location was at the manhole, with seven smoke source observations through holes in the cover or other leaks around the manhole. These defects were corrected by replacing vented manhole covers and by repairing the seal between the manhole frame and chimney interface as part of the Town s manhole rehabilitation program. Several main sewer defects located near several streams or storm channels were also discovered. These defects were investigated through additional CCTV inspection and dye testing to confirm whether they were direct I/I source connections and, if so, corrected. Seventy-seven I/I sources were observed on private property. The most common sources included defective cleanouts (with missing or vented caps), service laterals, area drains and downspouts. The Town continues to work with owners to eliminate private property cross connections. Element 4: Operation and Maintenance Program Page 44

The Town has contract vendors for significant, as-needed emergency repairs. This includes an annual point repair program for grade 4 and grade 5 sewer main deficiencies. Large repairs or pipe failures are referred to Engineering for inclusion in CIP projects and bids. 6.5 Resources and Budget The Town allocates funding for the operation, maintenance and repair of its collection system through its sanitary sewer enterprise fund Rate Paying Structure The current sewer rates were adopted in The Town s rates can be found on the Finance Department website at The Town hired a sewer rate consultant to establish the 2011 adopted sewer rates. These sewer rates, coupled with borrowings from the State s Revolving Loan Fund and the capital reserves, will pay for the near-term rehabilitation and replacement of sanitary sewer infrastructure. The Town will be undergoing another sewer rate study during the 2014/15 budget cycle. All budgets and association rate studies are reviewed by the Town s Financial Advisory Committee annually and are approved by the Town s City Council. The Town s annual budgets can be found on the Town s Finance Department webpage Capital Improvement Plan The Town has a three-year business plan that includes a five-year capital improvement program. The approved Three-Year CIP budget for Fiscal year 2014/15 can be found in the Town s FY 2014/15 Adopted Budget, available on the Town s Finance Department webpage at Individual CIP projects run cradle-to-grave and therefore can begin before and continue beyond any current budget cycle. The Five-Year CIP will only identify funds being newly allocated to the existing project. The sanitary sewer rehabilitation, inflow/infiltration improvements and capital Town upgrades (Sewer CIP) requires long-term conceptual planning. The Town is currently addressing compliance with an Administrative Civil Liability by the RWQCB resulting from sewer overflows. Compliance to the cease and desist order is projected to be in excess of $25M, partially funded by cost sharing with two other agencies and a State Revolving Fund loan. In addition, the Town is in need of rehabilitating its storm drain infrastructure in order to fix deficiencies that may cause localized flooding, landslides and infiltration into the sewer system. The master plan study completed in 2014 indicates a range of $16M (for medium to high priority repairs) to $32M (for all repairs). Currently, storm drain improvements are only funded by a $7.32 parcel tax and sewer rates. These sources are inadequate for the storm drain needs. The Town will be evaluating new sources of funding for these projects. Additional information can be found in the Town s FY 2014/15 Adopted Budget, available on the Town s Finance Department webpage at Element 4: Operation and Maintenance Program Page 45

Element 6: Overflow Emergency Response Plan This chapter provides a brief overview and description of the Town s Sanitary Sewer Overflow Emergency Response Plan (OERP). 8.1 Overflow Emergency Response Plan The purpose of Hillsborough s Sanitary Sewer Overflow Emergency Response Plan is to support an orderly and effective response to Sanitary Sewer Overflows. The OERP provides step-by-step guidelines for Town personnel to follow in responding to, cleaning up and reporting SSOs that may occur within the Town s service area. Town employees, contractors and residents are trained and educated to immediately notify the Town in the event of a possible sanitary sewer overflow by calling the Public Works Department main line during normal business hours, or the Town s Police Department Dispatch number at during non-business hours. The Town s Public Works employees are required to report all wastewater overflows found and to take the appropriate action to secure the wastewater overflow area, properly report to the appropriate regulatory agencies, relieve the cause of the overflow and ensure that the affected area is cleaned as soon as possible to minimize health hazards to the public and protect the environment. The Town s goal is to respond to sewer system overflows as soon as possible following notification. The Town will follow reporting procedures in regards to sewer spills as set forth by the San Francisco Regional Water Quality Control Board and the California State Water Resources Control Board. Sewer Division employees enter all SSO information into CIWQS, as described on the website and in the California Water Board s Enrollee s Guide to the SSO Database. All Town personnel who may have a role in responding to, reporting and/or mitigating a sewer system overflow receive training on the contents of the OERP. All new employees receive training before they are placed in a position where they may have to respond to SSOs. Current employees receive annual refresher training on the OERP. The Town documents all OERP training. SSO First Responders are well trained and are responsible for ensuring proper event documentation and photographs, timely reporting to appropriate agencies and the collection of water samples as necessary. After the event, the SSO First Responder is responsible for communicating the details of the event to management, ensuring all necessary paperwork is completed in full. The Town s Sewer Supervisor and the Public Work Superintendent are responsible for developing a plan to prevent future spills, whether through modifications to preventative maintenance activities or coordinating with engineering for structural rehabilitation or replacement. The Town s OERP was updated in April 2014 and is provided as Appendix D. Element 6: Overflow Emergency Response Plan Page 51

Element 7: Fats, Oils and Grease Control Program The SWRCB Order No DWR states that wastewater collection agencies shall evaluate their service area to determine whether a FOG (Fats, Oils and Grease) Control program is needed. In the mid s, the Town s conducted a FOG survey. The survey identified only seven facilities that produce measurable amounts of fats, oils and grease, as follows: Four public schools; Two private schools; and One country club. The remainder of the Town, except for municipal facilities, consists of single family homes. The Town worked with the seven identified food service facilities to either improve their grease interceptor or to install a new grease control device that conforms to the California Plumbing Code and the San Mateo Environmental Health Department requirements. Further, the survey found only six areas within the sewer conveyance system with signs of significant FOG buildup or accumulation, which included three of the Town s four sewer pump stations. These FOG areas have regularly scheduled in Lucity. The Town has the legal authority to prohibit discharges of FOG that could result in sanitary sewer system blockages and SSOs. The Town also has the authority to inspect grease producing facilities. However, the County Environmental Health Department is responsible for regular inspections of FOG producing commercial and school establishments within the Town. The Town also makes annual visits to these sites to provide educational information. Despite the fact that Hillsborough consists of single family homes and has very few areas with FOG issues, the Town conducts FOG outreach on a periodic basis, primarily through water bill stuffers, newsletter articles, e-notify messages and Town website content ( Fat, oil and grease buildup in the Town s sanitary sewer collection system is effectively controlled during the Town s regular preventative maintenance cleaning schedule. However, the Town s sewer field crews are trained to identify and report possible FOG issues to their supervisor so that the Division can investigate and take further action.

Element 8: System Evaluation and Capacity Assurance Plan The purpose of this chapter is to describe the Town s process to assess its current and future capacity requirements for its sanitary sewer collection system facilities Capacity Assurance The Town has conducted several capacity assessments of its wastewater collection system. The purpose of the assessments is to document the condition and capacity of the existing Town wastewater infrastructure, determine future facility requirements, and develop recommendations for near-term and longer-term improvements. Flow monitoring and system modeling (capacity analysis) were performed by Brown and Caldwell, Inc. on the 2011 Burlingame Sewershed Master Plan and RMC Water and Environment, Inc. performed flow monitoring and system modeling on the 2011 San Mateo Sewershed Master Plan. Both plans were updated in Additional modeling was performed in 2014, but additional flow monitoring was not performed. The Town is actively implementing the recommendations outlined in the master plans. The plans are available upon request Historical Information The Town s first comprehensive study of its sanitary sewer system was an Infiltration and Inflow (I&I) Study completed in The study divided the sanitary sewer system into twelve sewer basins, six of which flow into the San Mateo sewershed system south, and six of which flow into the Burlingame sewershed system north.

The study also included hydraulic analyses that identified the Crystal Springs/El Cerrito trunk sewer as being capacity deficient. The study concluded that sewer system rehabilitation to reduce I/I in the Lakeview and Crystal Springs basins would be cost-effective. Subsequent to the 1991 study, the Town required that developers conduct studies in the Lakeview and Crystal Springs basins, including additional flow monitoring at eight locations within the established 12 basins. The project also included further studies to develop recommendations for improvements to the Crystal Springs/El Cerrito trunk to the South and the Sanchez line to the North. Surveying, development of a hydraulic model, and closed-circuit television (CCTV) inspection of the Crystal Springs/El Cerrito trunk sewer to assess the capacity of the sewer and determine required improvements were conducted. Additional studies included 2011 smoke testing and CCTV inspection of sewers in portions of the Crystal Springs and Lakeview basins (sub-basins 2 and 7), which were identified as being cost-effective for I/I reduction. Hillsborough subsequently completed about 24,000 feet of sewer rehabilitation in these areas, and designed and constructed the Phase I Crystal Springs Sewer Improvement Project, which is comprised of 4,350 feet of new 24-inch diameter trunk sewer from Polhemus Road to Woodridge Road. Design of the Phase II Project, which will extend 10,700 feet downstream along Crystal Springs Road and El Cerrito Avenue to the San Mateo city limits, is also complete and the project is currently out to bid, with construction tentatively scheduled to start in the summer of 2014, concurrent with the construction of the downstream system upgrade through San Mateo to the waste water treatment plant.

Element 9: Monitoring, Measurement and Program Modifications This chapter discusses the Town s plans for monitoring and measuring the effectiveness of its SSMP, as well as procedures for making modifications to any part of its SSMP program Information Management As detailed in the Collection System Information Management and Mapping in Element 4, the Town utilizes CMMS, GIS and GPS software to manage and maintain all relevant information and data about its sanitary sewer system necessary to evaluate its performance. The Town also utilizes CIWQS ( to track SSOs and other relevant information SSMP Implementation The Town will assess its implementation of its SSMP annually in March. The Town will use performance indicators outlined in its Sanitary Sewer Management Plan as a basis to monitor and measure its ongoing performance. The Town will compare the results of these measurements against annual stated goals and prior years performance. In addition, the SSD Supervisor will informally track performance against indicators on a quarterly basis.

Element 10: SSMP Internal Audits The Town will audit its SSMP every two years, with the next audit due March 15, (The audit has been entered into Lucity as a pre-scheduled regulatory task.) The SSMP audit will consider any updates to the WDR or other regulatory requirements. It will then compare the Town s SSMP to its current sanitary sewer maintenance practices to determine whether the Town is following its SSMP. Finally, it will make recommendations to adjust the SSMP and/or Town sanitary sewer maintenance practices. It is anticipated that the audit will be conducted in coordination with an outside consultant. SSD staff will form the audit team and the consultant will guide the audit process. The scope of the audit will cover each of the sections of the SSMP (in addition to any changes to the SSMP guidelines). The audit team will also compare the SSDs actual performance against its performance indicators contained in Element 9 (Monitoring, Measurement and Program Modifications). It is anticipated that the audit will utilize existing SSMP audit checklist(s) in combination with audit preparation and qualitative analysis methodologies similar those outlined in Section 3, Phase IV of the EPA s Achieving Environmental Excellence: An Environmental Management Systems (EMS) Handbook for Wastewater Utilities (provided as Appendix J). The State Water Resources Control Board s Sewer Collection System Pre- Inspection Questionnaire may also serve as a reference and preparation guide. This Questionnaire, along with two example SSMP audit checklists and Phase IV of the EMS have been provided as reference and guidance material as Appendix K. These guidance documents will be referenced by the SSD in preparation of the March 2016 audit. It is anticipated that the Town will work with the selected audit consultant to refine the SSMP audit checklist and process based on best available current standards at the time the SSMP audit takes place. The results of the audit will be included in an SSMP Audit Report. The Audit Report will evaluate Hillsborough s successes in implementing the most recent version of its SSMP elements and identify revisions that may be needed for a more effective program. The Town will update its SSMP at least every five years. The next update will be completed on or before March 15, The Town acknowledges that it may the need to update its SSMP more frequently based on the results of its biannual audits, changes to the regulatory environment and/or the performance of its sanitary sewer system. In the event that an SSMP audit determines that an update of Hillsborough s SSMP is warranted, the process to complete the update will be identified at that time. The Town will endeavor to complete the update within six months following identification of the need for the update. The Public Works Department will seek the approval from the City Council for any significant programmatic changes to the SSMP. The authority for approval of modest informational or procedural changes is delegated to the Public Works Director. Element 10: SSMP Internal Audits Page 61

81 STATE WATER RESOURCES CONTROL BOARD ORDER NO DWQ STATEWIDE GENERAL WASTE DISCHARGE REQUIREMENTS FOR SANITARY SEWER SYSTEMS The State Water Resources Control Board, hereinafter referred to as State Water Board, finds that: 1. All federal and state agencies, municipalities, counties, districts, and other public entities that own or operate sanitary sewer systems greater than one mile in length that collect and/or convey untreated or partially treated wastewater to a publicly owned treatment facility in the State of California are required to comply with the terms of this Order. Such entities are hereinafter referred to as Enrollees. 2. Sanitary sewer overflows (SSOs) are overflows from sanitary sewer systems of domestic wastewater, as well as industrial and commercial wastewater, depending on the pattern of land uses in the area served by the sanitary sewer system. SSOs often contain high levels of suspended solids, pathogenic organisms, toxic pollutants, nutrients, oxygen-demanding organic compounds, oil and grease and other pollutants. SSOs may cause a public nuisance, particularly when raw untreated wastewater is discharged to areas with high public exposure, such as streets or surface waters used for drinking, fishing, or body contact recreation. SSOs may pollute surface or ground waters, threaten public health, adversely affect aquatic life, and impair the recreational use and aesthetic enjoyment of surface waters. 3. Sanitary sewer systems experience periodic failures resulting in discharges that may affect waters of the state. There are many factors (including factors related to geology, design, construction methods and materials, age of the system, population growth, and system operation and maintenance), which affect the likelihood of an SSO. A proactive approach that requires Enrollees to ensure a system-wide operation, maintenance, and management plan is in place will reduce the number and frequency of SSOs within the state. This approach will in turn decrease the risk to human health and the environment caused by SSOs. 4. Major causes of SSOs include: grease blockages, root blockages, sewer line flood damage, manhole structure failures, vandalism, pump station mechanical failures, power outages, excessive storm or ground water inflow/infiltration, debris blockages, sanitary sewer system age and construction material failures, lack of proper operation and maintenance, insufficient capacity and contractorcaused damages. Many SSOs are preventable with adequate and appropriate facilities, source control measures and operation and maintenance of the sanitary sewer system.

82 State Water Resources Control Board Order No DWQ Page 2 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 SEWER SYSTEM MANAGEMENT PLANS 5. To facilitate proper funding and management of sanitary sewer systems, each Enrollee must develop and implement a system-specific Sewer System Management Plan (SSMP). To be effective, SSMPs must include provisions to provide proper and efficient management, operation, and maintenance of sanitary sewer systems, while taking into consideration risk management and cost benefit analysis. Additionally, an SSMP must contain a spill response plan that establishes standard procedures for immediate response to an SSO in a manner designed to minimize water quality impacts and potential nuisance conditions. 6. Many local public agencies in California have already developed SSMPs and implemented measures to reduce SSOs. These entities can build upon their existing efforts to establish a comprehensive SSMP consistent with this Order. Others, however, still require technical assistance and, in some cases, funding to improve sanitary sewer system operation and maintenance in order to reduce SSOs. 7. SSMP certification by technically qualified and experienced persons can provide a useful and cost-effective means for ensuring that SSMPs are developed and implemented appropriately. 8. It is the State Water Board s intent to gather additional information on the causes and sources of SSOs to augment existing information and to determine the full extent of SSOs and consequent public health and/or environmental impacts occurring in the State. 9. Both uniform SSO reporting and a centralized statewide electronic database are needed to collect information to allow the State Water Board and Regional Water Quality Control Boards (Regional Water Boards) to effectively analyze the extent of SSOs statewide and their potential impacts on beneficial uses and public health. The monitoring and reporting program required by this Order and the attached Monitoring and Reporting Program No DWQ, are necessary to assure compliance with these waste discharge requirements (WDRs). 10. Information regarding SSOs must be provided to Regional Water Boards and other regulatory agencies in a timely manner and be made available to the public in a complete, concise, and timely fashion. 11. Some Regional Water Boards have issued WDRs or WDRs that serve as National Pollution Discharge Elimination System (NPDES) permits to sanitary sewer system owners/operators within their jurisdictions. This Order establishes minimum requirements to prevent SSOs. Although it is the State Water Board s intent that this Order be the primary regulatory mechanism for sanitary sewer systems statewide, Regional Water Boards may issue more stringent or more

83 State Water Resources Control Board Order No DWQ Page 3 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 prescriptive WDRs for sanitary sewer systems. Upon issuance or reissuance of a Regional Water Board s WDRs for a system subject to this Order, the Regional Water Board shall coordinate its requirements with stated requirements within this Order, to identify requirements that are more stringent, to remove requirements that are less stringent than this Order, and to provide consistency in reporting. REGULATORY CONSIDERATIONS 12. California Water Code section provides that the State Water Board may prescribe general WDRs for a category of discharges if the State Water Board finds or determines that: The discharges are produced by the same or similar operations; The discharges involve the same or similar types of waste; The discharges require the same or similar treatment standards; and The discharges are more appropriately regulated under general discharge requirements than individual discharge requirements. This Order establishes requirements for a class of operations, facilities, and discharges that are similar throughout the state. 13. The issuance of general WDRs to the Enrollees will: a) Reduce the administrative burden of issuing individual WDRs to each Enrollee; b) Provide for a unified statewide approach for the reporting and database tracking of SSOs; c) Establish consistent and uniform requirements for SSMP development and implementation; d) Provide statewide consistency in reporting; and e) Facilitate consistent enforcement for violations. 14. The beneficial uses of surface waters that can be impaired by SSOs include, but are not limited to, aquatic life, drinking water supply, body contact and noncontact recreation, and aesthetics. The beneficial uses of ground water that can be impaired include, but are not limited to, drinking water and agricultural supply. Surface and ground waters throughout the state support these uses to varying degrees. 15. The implementation of requirements set forth in this Order will ensure the reasonable protection of past, present, and probable future beneficial uses of water and the prevention of nuisance. The requirements implement the water quality control plans (Basin Plans) for each region and take into account the environmental characteristics of hydrographic units within the state. Additionally, the State Water Board has considered water quality conditions that could reasonably be achieved through the coordinated control of all factors that affect

84 State Water Resources Control Board Order No DWQ Page 4 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 water quality in the area, costs associated with compliance with these requirements, the need for developing housing within California, and the need to develop and use recycled water. 16. The Federal Clean Water Act largely prohibits any discharge of pollutants from a point source to waters of the United States except as authorized under an NPDES permit. In general, any point source discharge of sewage effluent to waters of the United States must comply with technology-based, secondary treatment standards, at a minimum, and any more stringent requirements necessary to meet applicable water quality standards and other requirements. Hence, the unpermitted discharge of wastewater from a sanitary sewer system to waters of the United States is illegal under the Clean Water Act. In addition, many Basin Plans adopted by the Regional Water Boards contain discharge prohibitions that apply to the discharge of untreated or partially treated wastewater. Finally, the California Water Code generally prohibits the discharge of waste to land prior to the filing of any required report of waste discharge and the subsequent issuance of either WDRs or a waiver of WDRs. 17. California Water Code section requires a water board to, after any necessary hearing, prescribe requirements as to the nature of any proposed discharge, existing discharge, or material change in an existing discharge. The requirements shall, among other things, take into consideration the need to prevent nuisance. 18. California Water Code section 13050, subdivision (m), defines nuisance as anything which meets all of the following requirements: a. Is injurious to health, or is indecent or offensive to the senses, or an obstruction to the free use of property, so as to interfere with the comfortable enjoyment of life or property. b. Affects at the same time an entire community or neighborhood, or any considerable number of persons, although the extent of the annoyance or damage inflicted upon individuals may be unequal. c. Occurs during, or as a result of, the treatment or disposal of wastes. 19. This Order is consistent with State Water Board Resolution No (Statement of Policy with Respect to Maintaining High Quality of Waters in California) in that the Order imposes conditions to prevent impacts to water quality, does not allow the degradation of water quality, will not unreasonably affect beneficial uses of water, and will not result in water quality less than prescribed in State Water Board or Regional Water Board plans and policies. 20. The action to adopt this General Order is exempt from the California Environmental Quality Act (Public Resources Code et seq.) because it is an action taken by a regulatory agency to assure the protection of the environment and the regulatory process involves procedures for protection of the environment. (Cal. Code Regs., tit. 14, 15308). In addition, the action to adopt

85 State Water Resources Control Board Order No DWQ Page 5 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 this Order is exempt from CEQA pursuant to Cal.Code Regs., title 14, to the extent that it applies to existing sanitary sewer collection systems that constitute existing facilities as that term is used in Section 15301, and 15302, to the extent that it results in the repair or replacement of existing systems involving negligible or no expansion of capacity. 21. The Fact Sheet, which is incorporated by reference in the Order, contains supplemental information that was also considered in establishing these requirements. 22. The State Water Board has notified all affected public agencies and all known interested persons of the intent to prescribe general WDRs that require Enrollees to develop SSMPs and to report all SSOs. 23. The State Water Board conducted a public hearing on February 8, 2006, to receive oral and written comments on the draft order. The State Water Board received and considered, at its May 2, 2006, meeting, additional public comments on substantial changes made to the proposed general WDRs following the February 8, 2006, public hearing. The State Water Board has considered all comments pertaining to the proposed general WDRs. IT IS HEREBY ORDERED, that pursuant to California Water Code section 13263, the Enrollees, their agents, successors, and assigns, in order to meet the provisions contained in Division 7 of the California Water Code and regulations adopted hereunder, shall comply with the following: A. DEFINITIONS 1. Sanitary sewer overflow (SSO) - Any overflow, spill, release, discharge or diversion of untreated or partially treated wastewater from a sanitary sewer system. SSOs include: (i) Overflows or releases of untreated or partially treated wastewater that reach waters of the United States; (ii) Overflows or releases of untreated or partially treated wastewater that do not reach waters of the United States; and (iii) Wastewater backups into buildings and on private property that are caused by blockages or flow conditions within the publicly owned portion of a sanitary sewer system. 2. Sanitary sewer system Any system of pipes, pump stations, sewer lines, or other conveyances, upstream of a wastewater treatment plant headworks used to collect and convey wastewater to the publicly owned treatment facility. Temporary storage and conveyance facilities (such as vaults, temporary piping, construction trenches, wet wells, impoundments, tanks, etc.) are considered to be part of the sanitary sewer system, and discharges into these temporary storage facilities are not considered to be SSOs.

86 State Water Resources Control Board Order No DWQ Page 6 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 For purposes of this Order, sanitary sewer systems include only those systems owned by public agencies that are comprised of more than one mile of pipes or sewer lines. 3. Enrollee - A federal or state agency, municipality, county, district, and other public entity that owns or operates a sanitary sewer system, as defined in the general WDRs, and that has submitted a complete and approved application for coverage under this Order. 4.

The web address for this site is This online database is maintained on a secure site and is controlled by unique usernames and passwords. 5. Untreated or partially treated wastewater Any volume of waste discharged from the sanitary sewer system upstream of a wastewater treatment plant headworks. 6. Satellite collection system The portion, if any, of a sanitary sewer system owned or operated by a different public agency than the agency that owns and operates the wastewater treatment facility to which the sanitary sewer system is tributary. 7. Nuisance - California Water Code section 13050, subdivision (m), defines nuisance as anything which meets all of the following requirements: a. Is injurious to health, or is indecent or offensive to the senses, or an obstruction to the free use of property, so as to interfere with the comfortable enjoyment of life or property. b. Affects at the same time an entire community or neighborhood, or any considerable number of persons, although the extent of the annoyance or damage inflicted upon individuals may be unequal. c. Occurs during, or as a result of, the treatment or disposal of wastes. B. APPLICATION REQUIREMENTS 1. Deadlines for Application All public agencies that currently own or operate sanitary sewer systems within the State of California must apply for coverage under the general WDRs within six (6) months of the date of adoption of the general WDRs. Additionally, public agencies that acquire or assume responsibility for operating sanitary sewer systems after the date of adoption of this Order must apply for coverage under the general WDRs at least three (3) months prior to operation of those facilities. 2. Applications under the general WDRs In order to apply for coverage pursuant to the general WDRs, a legally authorized representative for each agency must submit a complete application package. Within sixty (60) days of adoption of the general WDRs, State Water Board staff will send specific instructions on how to

87 State Water Resources Control Board Order No DWQ Page 7 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 apply for coverage under the general WDRs to all known public agencies that own sanitary sewer systems. Agencies that do not receive notice may obtain applications and instructions online on the Water Board s website. 3. Coverage under the general WDRs Permit coverage will be in effect once a complete application package has been submitted and approved by the State Water Board s Division of Water Quality. C. PROHIBITIONS 1. Any SSO that results in a discharge of untreated or partially treated wastewater to waters of the United States is prohibited. 2. Any SSO that results in a discharge of untreated or partially treated wastewater that creates a nuisance as defined in California Water Code Section 13050(m) is prohibited. D. PROVISIONS 1. The Enrollee must comply with all conditions of this Order. Any noncompliance with this Order constitutes a violation of the California Water Code and is grounds for enforcement action. 2. It is the intent of the State Water Board that sanitary sewer systems be regulated in a manner consistent with the general WDRs. Nothing in the general WDRs shall be: (i) (ii) Interpreted or applied in a manner inconsistent with the Federal Clean Water Act, or supersede a more specific or more stringent state or federal requirement in an existing permit, regulation, or administrative/judicial order or Consent Decree; Interpreted or applied to authorize an SSO that is illegal under either the Clean Water Act, an applicable Basin Plan prohibition or water quality standard, or the California Water Code; (iii) Interpreted or applied to prohibit a Regional Water Board from issuing an individual NPDES permit or WDR, superseding this general WDR, for a sanitary sewer system, authorized under the Clean Water Act or California Water Code; or (iv) Interpreted or applied to supersede any more specific or more stringent WDRs or enforcement order issued by a Regional Water Board. 3. The Enrollee shall take all feasible steps to eliminate SSOs. In the event that an SSO does occur, the Enrollee shall take all feasible steps to contain and mitigate the impacts of an SSO. 4. In the event of an SSO, the Enrollee shall take all feasible steps to prevent untreated or partially treated wastewater from discharging from storm drains into

88 State Water Resources Control Board Order No DWQ Page 8 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 flood control channels or waters of the United States by blocking the storm drainage system and by removing the wastewater from the storm drains. 5. All SSOs must be reported in accordance with Section G of the general WDRs. 6. In any enforcement action, the State and/or Regional Water Boards will consider the appropriate factors under the duly adopted State Water Board Enforcement Policy. And, consistent with the Enforcement Policy, the State and/or Regional Water Boards must consider the Enrollee s efforts to contain, control, and mitigate SSOs when considering the California Water Code Section factors. In assessing these factors, the State and/or Regional Water Boards will also consider whether: (i) The Enrollee has complied with the requirements of this Order, including requirements for reporting and developing and implementing a SSMP; (ii) The Enrollee can identify the cause or likely cause of the discharge event; (iii) There were no feasible alternatives to the discharge, such as temporary storage or retention of untreated wastewater, reduction of inflow and infiltration, use of adequate backup equipment, collecting and hauling of untreated wastewater to a treatment facility, or an increase in the capacity of the system as necessary to contain the design storm event identified in the SSMP. It is inappropriate to consider the lack of feasible alternatives, if the Enrollee does not implement a periodic or continuing process to identify and correct problems. (iv) The discharge was exceptional, unintentional, temporary, and caused by factors beyond the reasonable control of the Enrollee; (v) The discharge could have been prevented by the exercise of reasonable control described in a certified SSMP for: Proper management, operation and maintenance; Adequate treatment facilities, sanitary sewer system facilities, and/or components with an appropriate design capacity, to reasonably prevent SSOs (e.g., adequately enlarging treatment or collection facilities to accommodate growth, infiltration and inflow (I/I), etc.); Preventive maintenance (including cleaning and fats, oils, and grease (FOG) control); Installation of adequate backup equipment; and Inflow and infiltration prevention and control to the extent practicable. (vi) The sanitary sewer system design capacity is appropriate to reasonably prevent SSOs.

89 State Water Resources Control Board Order No DWQ Page 9 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 (vii) The Enrollee took all reasonable steps to stop and mitigate the impact of the discharge as soon as possible. 7. When a sanitary sewer overflow occurs, the Enrollee shall take all feasible steps and necessary remedial actions to 1) control or limit the volume of untreated or partially treated wastewater discharged, 2) terminate the discharge, and 3) recover as much of the wastewater discharged as possible for proper disposal, including any wash down water. The Enrollee shall implement all remedial actions to the extent they may be applicable to the discharge and not inconsistent with an emergency response plan, including the following: (i) Interception and rerouting of untreated or partially treated wastewater flows around the wastewater line failure; (ii) Vacuum truck recovery of sanitary sewer overflows and wash down water; (iii) Cleanup of debris at the overflow site; (iv) System modifications to prevent another SSO at the same location; (v) Adequate sampling to determine the nature and impact of the release; and (vi) Adequate public notification to protect the public from exposure to the SSO. 8. The Enrollee shall properly, manage, operate, and maintain all parts of the sanitary sewer system owned or operated by the Enrollee, and shall ensure that the system operators (including employees, contractors, or other agents) are adequately trained and possess adequate knowledge, skills, and abilities. 9. The Enrollee shall allocate adequate resources for the operation, maintenance, and repair of its sanitary sewer system, by establishing a proper rate structure, accounting mechanisms, and auditing procedures to ensure an adequate measure of revenues and expenditures. These procedures must be in compliance with applicable laws and regulations and comply with generally acceptable accounting practices. 10. The Enrollee shall provide adequate capacity to convey base flows and peak flows, including flows related to wet weather events. Capacity shall meet or exceed the design criteria as defined in the Enrollee s System Evaluation and Capacity Assurance Plan for all parts of the sanitary sewer system owned or operated by the Enrollee. 11. The Enrollee shall develop and implement a written Sewer System Management Plan (SSMP) and make it available to the State and/or Regional Water Board upon request. A copy of this document must be publicly available at the Enrollee s office and/or available on the Internet. This SSMP must be approved by the Enrollee s governing board at a public meeting.

(vi) Overflow Emergency Response Plan - Each Enrollee 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 an appropriate response to all overflows; (c) Procedures to ensure prompt notification to appropriate regulatory agencies and other potentially affected entities (e.g. health agencies, Regional Water Boards, water suppliers, etc.) of all SSOs that potentially affect public health or reach the waters of the State in accordance with the MRP. All SSOs shall be reported in accordance with this MRP, the California Water Code, other State Law, and other applicable Regional Water Board WDRs or NPDES permit requirements. The SSMP should identify the officials who will receive immediate notification; (d) Procedures to ensure that appropriate staff and contractor personnel are aware of and follow the Emergency Response Plan and are appropriately trained; (e) Procedures to address emergency operations, such as traffic and crowd control and other necessary response activities; and (f) A program to ensure that all reasonable steps are taken to contain and prevent the discharge of untreated and partially treated wastewater to waters of the United States and to minimize or correct any adverse impact on the environment resulting from the SSOs, including such accelerated or additional monitoring as may be necessary to determine the nature and impact of the discharge.

93 State Water Resources Control Board Order No DWQ Page 13 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 (vii) FOG Control Program: Each Enrollee shall evaluate its service area to determine whether a FOG control program is needed. If an Enrollee determines that a FOG program is not needed, the Enrollee must provide justification for why it is not needed. If FOG is found to be a problem, the Enrollee must prepare and implement a FOG source control program to reduce the amount of these substances discharged to the sanitary sewer system. This plan shall include the following as appropriate: (a) An implementation plan and schedule for a public education outreach program that promotes proper disposal of FOG; (b) A plan and schedule for the disposal of FOG generated within the sanitary sewer system service area. This may include a list of acceptable disposal facilities and/or additional facilities needed to adequately dispose of FOG generated within a sanitary sewer system service area; (c) The legal authority to prohibit discharges to the system and identify measures to prevent SSOs and blockages caused by FOG; (d) Requirements to install grease removal devices (such as traps or interceptors), design standards for the removal devices, maintenance requirements, BMP requirements, record keeping and reporting requirements; (e) Authority to inspect grease producing facilities, enforcement authorities, and whether the Enrollee has sufficient staff to inspect and enforce the FOG ordinance; (f) An identification of sanitary sewer system sections subject to FOG blockages and establishment of a cleaning maintenance schedule for each section; and (g) Development and implementation of source control measures for all sources of FOG discharged to the sanitary sewer system for each section identified in (f) above. (viii) System Evaluation and Capacity Assurance Plan: The Enrollee shall prepare and implement a capital improvement plan (CIP) that will provide hydraulic capacity of key sanitary sewer system elements for dry weather peak flow conditions, as well as the appropriate design storm or wet weather event. At a minimum, the plan must include: (a) Evaluation: Actions needed to evaluate those portions of the sanitary sewer system that are experiencing or contributing to an SSO discharge caused by hydraulic deficiency. The evaluation must provide estimates of peak flows (including flows from SSOs

94 State Water Resources Control Board Order No DWQ Page 14 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 that escape from the system) associated with conditions similar to those causing overflow events, estimates of the capacity of key system components, hydraulic deficiencies (including components of the system with limiting capacity) and the major sources that contribute to the peak flows associated with overflow events; (b) Design Criteria: Where design criteria do not exist or are deficient, undertake the evaluation identified in (a) above to establish appropriate design criteria; and (c) Capacity Enhancement Measures: The steps needed to establish a short- and long-term CIP to address identified hydraulic deficiencies, including prioritization, alternatives analysis, and schedules. The CIP may include increases in pipe size, I/I reduction programs, increases and redundancy in pumping capacity, and storage facilities. The CIP shall include an implementation schedule and shall identify sources of funding. (d) Schedule: The Enrollee shall develop a schedule of completion dates for all portions of the capital improvement program developed in (a)-(c) above. This schedule shall be reviewed and updated consistent with the SSMP review and update requirements as described in Section D. 14. (ix) Monitoring, Measurement, and Program Modifications: The Enrollee shall: (a) Maintain relevant information that can be used to establish and prioritize appropriate SSMP activities; (b) Monitor the implementation and, where appropriate, measure the effectiveness of each element of the SSMP; (c) Assess the success of the preventative maintenance program; (d) Update program elements, as appropriate, based on monitoring or performance evaluations; and (e) Identify and illustrate SSO trends, including: frequency, location, and volume. (x) SSMP Program Audits - As part of the SSMP, the Enrollee shall conduct periodic internal audits, appropriate to the size of the system and the number of SSOs. At a minimum, these audits must occur every two years and a report must be prepared and kept on file. This audit shall focus on evaluating the effectiveness of the SSMP and the

95 State Water Resources Control Board Order No DWQ Page 15 of 20 Statewide General WDR For Wastewater Collection Agencies 5/2/06 Enrollee s compliance with the SSMP requirements identified in this subsection (D.13), including identification of any deficiencies in the SSMP and steps to correct them. (xi) Communication Program The Enrollee shall communicate on a regular basis with the public on the development, implementation, and performance of its SSMP. The communication system shall provide the public the opportunity to provide input to the Enrollee as the program is developed and implemented. The Enrollee shall also create a plan of communication with systems that are tributary and/or satellite to the Enrollee s sanitary sewer system. 14. Both the SSMP and the Enrollee s program to implement the SSMP must be certified by the Enrollee to be in compliance with the requirements set forth above and must be presented to the Enrollee s governing board for approval at a public meeting. The Enrollee shall certify that the SSMP, and subparts thereof, are in compliance with the general WDRs within the time frames identified in the time schedule provided in subsection D.15, below.

117 AMENDED MONITORING AND REPORTING PROGRAM FOR THE STATEWIDE GENERAL WASTE DISCHARGE REQUIREMENTS FOR SANITARY SEWER SYSTEMS BACKGROUND Water Code section (2001, A.B. 285) requires the State Water Resources Control Board (State Water Board) and Regional Water Quality Control Boards (collectively Water Boards) to gather comprehensive and specific Sanitary Sewer Overflow (SSO) information. Water Code section also requires the Water Boards to make available to the public information including but not limited to the cause, estimated volume, location, date, time, and duration of the SSO; whether the SSO reached or may have reached surface waters; the response and corrective action taken by the collection system owner or operator (hereafter, Enrollee) for each SSO event; and the contact information for each Enrollee. On May 2, 2006 the State Water Board adopted Water Quality Order DWQ, Statewide Waste Discharge Requirements for Sanitary Sewer Systems (hereafter, SSS WDRs) to address Water Code section requirements and develop the framework for the statewide Sanitary Sewer Overflow Reduction Program. The SSS WDRs Monitoring and Reporting Program (MRP) includes specific SSO notification and reporting and record keeping requirements to meet SSO reporting requirements in the Water Code and facilitate compliance monitoring and enforcement for violations. The State Water Board Executive Officer issued a revised MRP for the SSS WDRs on February 20, 2008 to rectify notification deficiencies that occurred early in program implementation and to ensure that first responders (e.g., Water Boards, California Office of Emergency Services, and County Health Departments) are notified in a timely manner for SSOs discharged to surface waters. Based on over six years of implementation of the SSS WDRs, the State Water Board concluded that the February 20, 2008 revised MRP is no longer adequate to advance the Sanitary Sewer Overflow Reduction Program objectives, assess compliance, and enforce the requirements of the SSS WDRs. Following its January 24, 2012 workshop with stakeholders for the review and update of the SSS WDRs, the State Water Board directed staff to review and evaluate the existing monitoring and reporting requirements and prepare an amended MRP for the Executive Director s issuance. Staff worked with the key stakeholders (e.g., California Association of Sanitation Agencies) to revise the monitoring and reporting requirements. State Water Board staff distributed the draft versions of the MRP to all stakeholders registered on the Lyris list for the Sanitary Sewer Overflow Reduction Program, solicited comments on the draft versions of the MRP in January and March 2013, and considered all comments received in developing the final revised MRP.

118 Fact Sheet for Order EXEC Page 2 of 3 Monitoring and Reporting Program for Order DWQ INSPECTION AND AUDIT FINDINGS Since January 2007, numerous violations of the SSS WDRs have been documented by the Water Boards through data review, compliance monitoring, and onsite inspections. The most common violations related to the MRP that the Water Boards have documented are: Failure to properly estimate and report SSO volumes discharged and recovered [violation of section G of the SSS WDRs] Failure of the Enrollee to comply with all minimum MRP record keeping requirements [violation of section G of the SSS WDRs] Failure of the Enrollee to implement feasible alternatives and actions necessary to identify and correct problems causing SSOs [violation of subsection D.6 of the SSS WDRs] Unauthorized use of legally responsible official s SSO Online Database login password and electronic signature; [violation of section J of the SSS WDRs] Failure of the Enrollee to develop and/or implement an Overflow Emergency Response Plan to ensure all reasonable steps are taken to contain and prevent the discharge of untreated and partially treated wastewater to waters of the United States and to minimize or correct any adverse impact on the environment resulting from the SSOs, including accelerated or additional monitoring necessary to determine the nature and impact of the SSO [violation of subsection D.13(vi) of the SSS WDRs] Failure of the Enrollee to implement required training for sewer system operators and contractors [violation of subsections D.13(iv) and D.13(vi) of the SSS WDRs] Amendments made to the MRP in Order EXEC address these and other issues that have become apparent in the implementation of the SSS WDRs in over six years. MONITORING AND REPORTING PROGRAM AMENDMENTS State Water Board staff and other members of the Data Review Committee reviewed the current SSS WDRs reporting requirements as part of the SSS WDRs review and update process. The Data Review Committee is open to all stakeholders. Consequently, enrollees, non-governmental organizations, and other agencies have participated. As a result of this process, new reporting requirements have been developed that address the compliance and enforcement issues noted above and improve the quality and usefulness of SSO data collected. While the proposed changes streamline the reporting process overall, some fields have been added to the reports. These additions address critical information gaps in the current reporting that have been identified both internally and by stakeholders. For example, many enrollees have noted that we need to be able to separate sewer lateral spills from spills occurring in other asset types like main lines or pump stations. The where did the failure occur question on the electronic spill report form was not a required field in the original or revised 2008 MRP. Many SSO reports do not have this information, thus, we cannot differentiate lateral spills from main line, pump station, or other types of spills. This is one example of the additions in the required data entry that have been addressed in the 2013 MRP revisions.

119 Fact Sheet for Order EXEC Page 3 of 3 Monitoring and Reporting Program for Order DWQ The following is a summary of major changes made to the existing MRP (Order EXEC) and incorporated in the final revised MRP (Order EXEC): 1. Change in Notification Requirement for spills that reach surface water: Three notification calls were required (California Office of Emergency Services, Regional Water Quality Control Boards, and local Health Departments). Required notification has been changed to call California Office of Emergency Services (Cal OES) only since Cal OES notifies the Regional Water Quality Control Boards and local Health Departments when a spill notification is received. Elimination of requirement to submit a certification to Regional Water Quality Control Boards within 24 hours of making notification calls. Alignment of notification requirement with California Code of Regulations section 2250, Reportable Quantity of Sewage, by requiring notification calls for only spills of 1,000 gallons or more. Notification of Cal OES was required for all spills to surface water. Addition of requirement to update Cal OES when there are substantial changes to previously reported spill volume estimates or impacts. 2. Defined new spill categories and refined spill report fields: Replacement of spill Categories 1 and 2 with Categories 1, 2, and 3. Spills are now classified as follows: Category 1 Spills of any volume that reach surface water Category 2 Spills greater than or equal to 1,000 gallons that do not reach surface water Category 3 (formerly Category 2) Spills less than 1,000 gallons that do not reach surface water All spills to surface water will be in a distinct category with this change. Spill reporting fields were refined and streamlined with stakeholder input. 3. Addition of requirement to submit a technical report within 45 days of the end date for spills to surface water over 50,000 gallons. 4. Addition of requirement for all Permit enrollees to develop a Water Quality Monitoring plan to be implemented within 48 hours after initial notification for spills where 50,000 gallons or more reach surface water. 5. Addition of requirement for Permit enrollees to submit an electronic copy of their Sewer System Management Plan (SSMP) or provide the web address where their SSMP is posted. 6. Addition of enhanced record keeping requirements. 7. Elimination of requirement to certify Private Lateral Sewer Discharge reports. 8. Addition of a 120-day time limit for amending and re-certifying spill reports.

130 Sanitary Sewer Overflow Emergency Response Plan (ref. SWRCB Order No DWQ Element VI) 1. Purpose The purpose of the Town of Hillsborough s Overflow Emergency Response Plan (OERP) is to support an orderly and effective response to Sanitary Sewer Overflows (SSOs). The OERP provides guidelines for Town personnel to follow in responding to, cleaning up, and reporting SSOs that may occur within the Town s service area. This OERP satisfies the SWRCB Statewide General Waste Discharge Requirements (GWDR), which require wastewater collection agencies to have an Overflow Emergency Response Plan. 2. Policy The Town s employees are required to report all wastewater overflows found and to take the appropriate action to secure the wastewater overflow area, properly report to the appropriate regulatory agencies, relieve the cause of the overflow, and ensure that the affected area is cleaned as soon as possible to minimize health hazards to the public and protect the environment. The Town s goal is to respond to sewer system overflows as soon as possible following notification. The Town will follow reporting procedures in regards to sewer spills as set forth by the San Francisco Regional Water Quality Control Board (SFRWQCB) and the California State Water Resources Control Board (SWRCB). 3. Definitions As Used In This OERP CALIFORNIA INTEGRATED WATER QUALITY SYSTEM (CIWQS): Refers to the State Water Resources Control Board online electronic reporting system that is used to report SSOs, certify completion of the SSMP, and provide information on the sanitary sewer system. FROG Fats, Roots, Oils, and Grease: FOG refers to fats, oils, and grease typically associated with food preparation and cooking activities that can cause blockages in the sanitary sewer system. Tree root invasion (R) presents an additional problem. If a mat of root hair forms in the sewer line it slows the flow of wastewater and exacerbates the rate of accumulation of FOG materials. LEGALLY RESPONSIBLE OFFICIAL (LRO): Refers to an individual who has the authority to certify reports and other actions that are submitted through CIWQS. MAINLINE SEWER: Refers to Town wastewater collection system piping that is not a private lateral connection to a user. MAINTENANCE HOLE OR MANHOLE: Refers to an engineered structure that is intended to provide access to a sanitary sewer for maintenance and inspection. NOTIFICATION OF AN SSO: Refers to the time at which the Town becomes aware of an SSO event through observation or notification by the public or other source. NUISANCE - California Water Code section 13050, subdivision (m), defines nuisance as anything that meets all of the following requirements: a. Is injurious to health, or is indecent or offensive to the senses, or an obstruction to the free use of property, so as to interfere with the comfortable enjoyment of life or property DKF Solutions Group, LLC. All rights reserved. OERP Page 3

131 b. Affects at the same time an entire community or neighborhood, or any considerable number of persons, although the extent of the annoyance or damage inflicted upon individuals may be unequal. c. Occurs during, or as a result of, the treatment or disposal of wastes. PREVENTATIVE MAINTENANCE: Refers to maintenance activities intended to prevent failures of the wastewater collection system facilities (e.g. cleaning, CCTV, inspection). PRIVATE LATERAL SEWAGE DISCHARGES Sewage discharges that are caused by blockages or other problems within a privately owned lateral. SANITARY SEWER OVERFLOW (SSO) - Any overflow, spill, release, discharge or diversion of untreated or partially treated wastewater from a sanitary sewer system. SSOs include: (i) Overflows or releases of untreated or partially treated wastewater that reach waters of the United States; (ii) Overflows or releases of untreated or partially treated wastewater that do not reach waters of the United States; and (iii) Wastewater backups into buildings and on private property that are caused by blockages or flow conditions within the publicly owned portion of a sanitary sewer system. SSOs that include multiple appearance points resulting from a single cause will be considered one SSO for documentation and reporting purposes in CIWQS. NOTE: Wastewater backups into buildings caused by a blockage or other malfunction of a building lateral that is privately owned are not SSOs. SSO Categories: Category 1: Category 2: Category 3: Discharge of untreated or partially treated wastewater of any volume resulting from a sanitary sewer system failure or flow condition that either: Reaches surface water and/or drainage channel tributary to a surface water; or Reached a Municipal Separate Storm Sewer System (MS4) and was not fully captured and returned to the sanitary sewer system or otherwise captured and disposed of properly. Discharge of untreated or partially treated wastewater greater than or equal to 1,000 gallons resulting from a sanitary sewer system failure or flow condition that either: Does not reach surface water, a drainage channel, or an MS4, or The entire SSO discharged to the storm drain system was fully recovered and disposed of properly. All other discharges of untreated or partially treated wastewater resulting from a sanitary sewer system failure or flow condition. SANITARY SEWER SYSTEM: Any publicly-owned system of pipes, pump stations, sewer lines, or other conveyances, upstream of a wastewater treatment plant headworks used to collect and convey wastewater to the publicly owned treatment facility. Temporary storage and conveyance facilities (such as vaults, temporary piping, construction trenches, wet wells, impoundments, tanks, etc.) are considered to be part of the sanitary sewer system, and discharges into these temporary storage facilities are not considered to be SSOs DKF Solutions Group, LLC. All rights reserved. OERP Page 4

132 SENSITIVE AREA: Refers to areas where an SSO could result in a fish kill or pose an imminent or substantial danger to human health (e.g. parks, aquatic habitats, etc.) SEWER SERVICE LATERAL: wastewater collection system. Refers to the piping that conveys sewage from the building to the Town s UNTREATED OR PARTIALLY TREATED WASTEWATER: Any volume of waste discharged from the sanitary sewer system upstream of a wastewater treatment plant headworks. WATERS OF THE STATE: Waters of the State (or waters of the United States) means any surface water, including saline waters, within the boundaries of California. In case of a sewage spill, storm drains are considered to be waters of the State unless the sewage is completely contained and returned to the wastewater collection system and that portion of the storm drain is cleaned. 4. State Regulatory Requirements for Element 6, Overflow Emergency Response Plan General Waste Discharge Requirement (GWDR) The collection system agency shall develop and implement an overflow emergency response plan that identifies measures to protect public health and the environment. At a minimum, this plan must include the following: (a) Proper notification procedures so that the primary responders and regulatory agencies are informed of all SSOs in a timely manner; (b) A program to ensure appropriate response to all overflows; (c) Procedures to ensure prompt notification to appropriate regulatory agencies and other potentially affected entities (e.g. health agencies, regional water boards, water suppliers, etc.) of all SSOs that potentially affect public health or reach the waters of the State in accordance with the Monitoring and Reporting Program (MRP). All SSOs shall be reported in accordance with this MRP, the California Water Code, other State Law, and other applicable Regional Water Board Waste Discharge Requirements or National Pollutant Discharge Elimination System (NPDES) permit requirements. The Sewer System Management Plan should identify the officials who will receive immediate notification; (d) Procedures to ensure that appropriate staff and contractor personnel are aware of and follow the Emergency Response Plan and are appropriately trained; (e) Procedures to address emergency operations, such as traffic and crowd control and other necessary response activities; and (f) A program to ensure that all reasonable steps are taken to contain untreated wastewater and prevent discharge of untreated wastewater to Waters of the United States and minimize or correct any adverse impact on the environment resulting from the SSOs, including such accelerated or additional monitoring as may be necessary to determine the nature and impact of the discharge. The Sewer System Management Plan and critical supporting documents are available to the public at 5. Goals The Town s goals with respect to responding to SSOs are: Work safely; Respond quickly to minimize the volume of the SSO; Eliminate the cause of the SSO; Prevent sewage system overflows or leaks from entering the storm drain system or receiving waters to the maximum extent practicable; Contain the spilled wastewater to the extent feasible; DKF Solutions Group, LLC. All rights reserved. OERP Page 5

133 Minimize public contact with the spilled wastewater; Mitigate the impact of the SSO; Meet the regulatory reporting requirements; Evaluate the causes of failure related to certain SSOs; and Revise response procedures resulting from the debrief and failure analysis of certain SSOs. 6. SSO Detection and Notification ref. SWRCB Order No DWQ VI(a) The processes that are employed to notify the Town of the occurrence of an SSO include: observation by the public, receipt of an alarm, or observation by Town staff during the normal course of their work. In the event of any pump failure at a Town wastewater lift station, the high level sensor activates the SCADA alarm system and the Town is contacted. To prevent overflow, wastewater from the wet well can either be pumped into a vacuum truck for disposal to a nearby sanitary sewer manhole, or bypassed around the station into the sanitary sewer system. 6.1 PUBLIC OBSERVATION Public observation is the most common way that the Town is notified of blockages and spills. Contact numbers and information for reporting sewer spills and backups are in the phone book and on the Town s website: The Town s telephone number for reporting sewer problems is (650) during business hours, and (650) after hours (Police Non- Emergency Dispatch). Normal Work Hours When a report of a sewer spill or backup is made during normal work hours, Public Works administrative staff receives the call, starts a Sewer Request form in the CMMS (Lucity), and then notifies the Sewer Department to respond to the call. The Sewer Supervisor contacts the customer and completes the Sewer Request Form. After Hours After hours service calls are received by Police Non-Emergency Dispatch, which receives the call and then notifies the On-Call Employee. The On-Call Employee initiates the reporting and tracking documentation by entering the information into the electronic CMMC system called Lucity. The information is put into a custom SSO spill report form, which associates the information with a point on the GIS map. The on-call staff also fills out hard copy field reports in the field, which are attached to the electronic file. When calls are received, either during normal work hours or after hours, the individual receiving the call will collect the following information: Time and date of call Specific location of potential overflow or incident Nature of call In case of SSO, estimated start time of overflow and how long it has been occurring Caller s name, telephone number and address Caller s observations (e.g., odor, duration, location on property, known impacts, indication if surface water impacted, appearance at cleanout or manhole) Other relevant information The following Fig. 6.1 is an overview of receiving a sewage overflow or backup report (see next page): DKF Solutions Group, LLC.

137 7.2 First Responder Priorities The first responder s priorities are: To follow safe work practices. To respond promptly with the appropriate and necessary equipment. To contain the spill wherever feasible. To restore the flow as soon as practicable. To minimize public access to and/or contact with the spilled sewage. To promptly notify the Sewer Supervisor in event of major SSO. To return the spilled sewage to the sewer system. To restore the area to its original condition (or as close as possible). To photograph and document affected and unaffected areas from a spill. 7.3 Safety The first responder is responsible for following safety procedures at all times. Special safety precautions must be observed when performing sewer work. There may be times when Town personnel responding to a sewer system event are not familiar with potential safety hazards peculiar to sewer work. In such cases it is appropriate to take the time to discuss safety issues, consider the order of work, and check safety equipment before starting the job. This includes use of gas monitoring detectors for air quality in manholes and traffic controls at the site. 7.4 Initial Response The first responder must respond to the reporting party/problem site and visually check for potential sewer stoppages or overflows. The first responder will: Note arrival time at the site of the overflow/backup. Verify the existence of a public sewer system spill or backup. Determine if the overflow or blockage is from a public or private sewer. Identify and assess the affected area and extent of spill. Contact caller if time permits. If the spill is large or in a sensitive area, document conditions upon arrival with photographs. Decide whether to proceed with clearing the blockage to restore the flow or to initiate containment measures. The guidance for this decision is: o Small spills (i.e., spills that are easily contained) proceed with clearing the blockage. o Moderate or large spill where containment is anticipated to be simple proceed with the containment measures. o Moderate or large spills where containment is anticipated to be difficult proceed with clearing the blockage; however, whenever deemed necessary, call for additional assistance and implement containment measures. Take steps to contain the SSO. For detailed procedures refer to Appendix B: Sanitary Sewer Backup Procedures, and Appendix C: Sanitary Sewer Overflow Packet. 7.6 Initiate Spill Containment Measures The first responder will attempt to contain as much of the spilled sewage as possible using the following steps: Determine the immediate destination of the overflowing sewage DKF Solutions Group, LLC. All rights reserved. OERP Page 10

138 Plug storm drains using air plugs, sandbags, and/or plastic mats to contain the spill, whenever appropriate. If spilled sewage has made contact with the storm drainage system, attempt to contain the spilled sewage by plugging downstream storm drainage facilities. Contain/direct the spilled sewage using dike/dam or sandbags. Pump around the blockage/pipe failure. For detailed procedures refer to Appendix C: Sanitary Sewer Overflow Packet. 7.5 Restore Flow Using the appropriate cleaning equipment, set up downstream of the blockage and hydro-clean upstream from a clear manhole. Attempt to remove the blockage from the system and observe the flows to ensure that the blockage does not reoccur downstream. If the blockage cannot be cleared within a reasonable time from arrival, or sewer requires construction repairs to restore flow, then initiate containment and/or bypass pumping. If assistance is required, immediately contact other employees, contractors, and equipment suppliers. For detailed procedures refer to Appendix C: Sanitary Sewer Overflow Packet. 7.6 Equipment This section provides a list of specialized equipment that is required to support this Overflow Emergency Response Plan. Closed Circuit Television (CCTV) Inspection Unit A CCTV Inspection Unit is required to determine the root cause for all SSOs from gravity sewers. Camera -- A digital or disposable camera is required to record the conditions upon arrival, during clean up, and upon departure. Emergency Response Trucks -- A utility body pickup truck, or open bed is required to store and transport the equipment needed to effectively respond to sewer emergencies. The equipment and tools will include containment and clean up materials. Portable Generators, Portable Pumps, Piping, and Hoses Equipment used to bypass pump, divert, or power equipment to mitigate an SSO. Combination Sewer Cleaning Trucks -- Combination high velocity sewer cleaning trucks with vacuum tanks are required to clear blockages in gravity sewers, vacuum spilled sewage, and wash down the impacted area following the SSO event. Air plugs, sandbags and plastic mats SSO Sampling Kits Standard operating procedures for equipment that may be necessary in the event of a sanitary sewer overflow or backup can be found in the Corporation Yard office. 7.7 Outside Assistance Responders will refer to the Emergency Response Vendor List as necessary for assistance with the response DKF Solutions Group, LLC.

139 8. Recovery and Cleanup ref. SWRCB Order No DWQ Element 6(e) The recovery and cleanup phase begins immediately after the flow has been restored and the spilled sewage has been contained to the extent possible. The SSO recovery and cleanup procedures are: 8.1 Estimate the Volume of Spilled Sewage Use the methods outlined in the Sanitary Sewer Backup Packet (Appendix B), Sanitary Sewer Overflow Packet (Appendix C), and/or the Field Guide to estimate the volume of the spilled sewage. Wherever possible, document the estimate using photos and/or video of the SSO site before and during the recovery operation. 8.2 Recovery of Spilled Sewage Vacuum up and/or pump the spilled sewage and rinse water, and discharge it back into the sanitary sewer system. 8.3 Clean-up and Disinfection Clean up and disinfection procedures will be implemented to reduce the potential for human health issues and adverse environmental impacts that are associated with an SSO event. The procedures described are for dry weather conditions and will be modified as required for wet weather conditions. Where cleanup is beyond the capabilities of Town staff, a cleanup contractor will be used. Private Property Town crews are responsible for the cleanup when the property damage is minor in nature and is outside of private building dwellings, such as in front, side and backyards, easements, etc. In all other cases, affected property owners can call a water damage restoration contractor to complete the cleanup and restoration. If the overflow into property is the definite cause of Town system failure, the property owner can call out a water damage restoration contractor to complete the cleanup and restoration. In both cases, Town claim forms may be issued if requested by the property owners. Hard Surface Areas Collect all signs of sewage solids and sewage-related material either by protected hand or with the use of rakes and brooms. Wash down the affected area with clean water and/or deozyme or similar non-toxic biodegradable surface disinfectant until the water runs clear. The flushing volume will be approximately three times the estimated volume of the spill. Take reasonable steps to contain and vacuum up the wastewater. Allow area to dry. Repeat the process if additional cleaning is required. Landscaped and Unimproved Natural Vegetation Collect all signs of sewage solids and sewage-related material either by protected hand or with the use of rakes and brooms. Wash down the affected area with clean water until the water runs clear. The flushing volume will be approximately three times the estimated volume of the spill. Either contain or vacuum up the wash water so that none is released. Allow the area to dry. Repeat the process if additional cleaning is required.

140 Wet Weather Modifications Omit flushing and sampling during heavy storm events (i.e., sheet of rainwater across paved surfaces) with heavy runoff where flushing is not required and sampling would not provide meaningful results. 8.4 Public Notification Signs will be posted and barricades put in place to keep vehicles and pedestrians away from contact with spilled sewage. County Environmental Health instructions and directions regarding placement and language of public warnings will be followed when directed. Additionally, the Public Works Superintendent or Sewer Supervisor will use their best judgment regarding supplemental sign placement in order to protect the public and local environment. Signs will not be removed until directed by County Environmental Health, Public Works Superintendent, Sewer Supervisor, or designee. Creeks, streams and beaches that have been contaminated as a result of an SSO will be posted at visible access locations until the risk of contamination has subsided to acceptable background bacteria levels. The warning signs, once posted, will be checked at least every day to ensure that they are still in place. Photographs of sign placement will be taken. In the event that an overflow occurs at night, the location will be inspected first thing the following day. The field crew will look for any signs of sewage solids and sewage-related material that may warrant additional cleanup activities. When contact with the local media is deemed necessary, the Building and Planning Director or their designee will provide the media with all revelvant information. 9. Water Quality ref.

141 9.2 Water Quality Sampling and Testing Water quality sampling and testing is required for Category 1 SSOs of 50,000 gallons or greater to determine the extent and impact of the SSO. Town policy is to collect water samples for SSOs of 50 gallons or greater. The water quality sampling procedures must be implemented within 48 hours and include the following: The first responders will collect samples as soon as possible after the discovery and mitigation of the SSO event. The water quality samples will be collected from upstream of the spill, from the spill area, and downstream of the spill in flowing water (e.g. creeks). The water quality samples will be collected near the point of entry of the spilled sewage. The samples shall then be brought to the San Francisco Public Utilities Commission s on-site lab for analysis. 9.3 Water Quality Monitoring Plan The Town Water Quality Monitoring Plan will be implemented immediately upon discovery of any Category 1 SSO of 50,000 gallons or more in order to assess impacts from SSOs to surface waters. The SSO Water Quality Monitoring Program will: 1. Contain protocols for water quality monitoring. 2. Account for spill travel time in the surface water and scenarios where monitoring may not be possible (e.g. safety, access restrictions, etc.) 3. Require water quality analyses for ammonia and bacterial indicators to be performed by an accredited or certified laboratory. 4. Require monitoring instruments and devices used to implement the SSO Water Quality Monitoring Program to be properly maintained and calibrated, including any records to document maintenance and calibration, as necessary, to ensure their continued accuracy. 5. Within 48 hours of the Town becoming aware of the SSO, require water quality sampling for ammonia and total and fecal coliform. 6. Observe proper chain of custody procedures. 9.4 SSO Technical Report The Town will submit an SSO Technical Report to the CIWQS Online SSO Database within 45 calendar days of the SSO end date for any SSO in which 50,000 gallons or greater are spilled to surface waters.

160 Town of Hillsborough: Overflow Emergency Response Plan Sanitary Sewer Backup Response Packet Bubbled Toilets Letter B-2 Dear Town of Hillsborough Customer, Thank you for informing us that your toilet bubbled while our crews were working in proximity of your property. We apologize for the inconvenience and hope that this letter will answer some of your questions about bubbling toilets. 1. Is this a health risk? The water that came out of your toilet is potable water from the toilet bowl. Unless your toilet was in use when this occurred, this water is no different than that encountered while cleaning your toilet. 2. What is the Town doing in the street? In order to insure reliable sewer service, the Town inspects, cleans, and repairs its sewer system on a continuous basis. 3. How does sewer cleaning cause my toilet to bubble? Typical industry cleaning equipment uses high-pressure water to clean sewers. The first step is to use the high-pressure water jets to propel the hose and cleaning nozzle upstream as far as 800 feet. During this process, air within the main pipe is displaced and sometimes goes up the private lateral pipe and releases though the toilet. This can also happen during the cleaning phase, when high-pressure water is pulled downstream to the cleaning truck. 4. What causes the air to come from my toilet? Over the years, Town crews have found that the bubbling of toilets have many causes, some of which are: Obstructed vent pipes; Vent pipes that are positioned too far from the toilet; Lateral pipes that may be in use as the crew is cleaning (e.g. draining washing machine, draining bathtub, etc.); Lateral pipes that may have obstructions that are causing them to hold water (e.g. roots, grease, etc.). 5. What does Town staff do, once informed of a bubbling toilet? Once notified of a bubbling toilet, the crew leader explains to the customer what has happened, and checks to see if there is a clean-out in the customer s yard that could be opened in the future during cleaning. The crew leader then makes notes and completes paperwork that puts the address on the Town s computerized notification list. In the future, crews will notice that this address was bubbled at one time, and, before commencing the cleaning, they will notify the occupant of the possibility of bubbling toilets. In the event the occupant is not present when the cleaning begins, the crews will attempt to open clean-outs and/or lower water pressure to avoid bubbling. 6. What can I do to prevent my toilet from bubbling? When a sewer begins to drain slowly, it may be a sign that it needs to be cleaned or repaired. Trees and shrubs may have root structures that are entering the lateral pipe. The homeowner needs to make sure to have a clean-out for accessing the line. It is the homeowner s responsibility to keep the sewer lateral pipe in good working condition. It is always a good idea to keep the toilet lid down when not in use, and not install carpets in the bathroom unless they can be easily removed and cleaned.

161 Town of Hillsborough: Overflow Emergency Response Plan Sanitary Sewer Backup Response Packet Carta de Inodoros Burbujeados B-2 Spanish Estimado Cliente de la Ciudad de Hillsborough: Gracias por habernos informado que su lavabo burbujeó mientras que nuestros empleados estaban trabajando en proximidad a su propiedad. Le pedimos perdón por la inconveniencia y esperamos que esta carta le contestará algunas de sus preguntas acerca de inodoros burbujeantes. 1. Es riesgo de salud esto? El agua que salió de su inodoro es agua potable de la taza del inodoro. Menos que su inodoro estaba en uso cuando esto ocurrió, esa agua no es diferente de aquella encontrada mientras que limpia su inodoro. 2. Qué está haciendo la Ciudad en la calle? Para asegurar servicio de alcantarilla confiable, la Ciudad inspecciona, limpia, and repara su Sistema de alcantarillado en una forma continua. 3. Cómo causa la limpieza de la alcantarilla que burbujee mi inodoro? El equipamiento industrial de limpieza típico usa agua de alta presión para limpiar alcantarillas. La primer medida es de usar chorros de agua de alta presión para propulsar a la manguera y a la boquilla de limpieza contracorriente tan lejos como ochocientos (800) pies. Durante este proceso, el aire dentro la tubería principal es desplazada y a veces camina para arriba de la tubería lateral privada y se libera por el inodoro. Esto también puede ocurrir durante la fase de limpieza, cuando agua de alta presión es jalada corriente abajo al camión de limpieza. 4. Qué causa al aire que venga de mi inodoro? A lo largo de los años, los empleados de la Ciudad han encontrado que el burbujeo de inodoros tiene muchas causas, algunas de cuales son: Tubería de ventilación obstruida; Tubería de ventilación que está posicionada muy lejos del inodoro; Tubería lateral que pueda estar en uso mientras que los empleados estén limpiando (por ej., vaciando la máquina de lavar, vaciando el baño, etcétera); Tubería lateral que podrá tener obstrucciones que están causándola a contener agua (por ej., raíces, grasa, etcétera). 5. Qué hace el personal de la Ciudad, una vez informados de un inodoro burbujeante? Una vez notificado de un inodoro burbujeante, el líder de nuestros empleados le explica al cliente lo que ha ocurrido, y hace un chequeo para ver si hay una limpieza general en el patio del cliente que se pudiera abrir en el futuro durante la limpieza. El líder de personal luego toma apuntes y completa papeleo que pone a la dirección en la lista de notificación computarizada de la Ciudad. En el futuro, los empleados tomarán nota que hubo un tiempo en que esta dirección fue «burbujeada», y, antes de empezar la limpieza, ellos le avisarán al ocupante de la posibilidad de inodoros burbujeantes. En el evento que el ocupante no esté presente cuando la limpieza empiece, los empleados tratarán de abrir las limpiezas generales y/o rebajar la presión del agua para impedir la ocurrencia de burbujeo. 6. Qué puede hacer para impedir a mi inodoro de burbujeando? Cuando una alcantarilla empieza a desaguar lentamente, puede que sea un indicio que se necesita limpiar o reparar. Puede que los árboles y arbustos tengan estructuras de raíces que estén entrando a la tubería lateral. El dueño/la dueña de casa necesita asegurar de tener una limpieza general para acceder la línea. Es la responsabilidad del dueño/la dueña de mantener la tubería de alcantarilla lateral en buena condición operativa. Siempre es buena idea de mantener la tapa del inodoro bajada cuando no esté el inodoro en uso, y no instalar alfombra en el cuarto de baño menos que esa se pueda quitar y limpiar. Para más información, por favor llame al Departamento de Obras Públicas por medio del número de teléfono (650) Atentamente, La Ciudad de Hillsborough DKF Solutions Group All rights reserved.

213 Sanitary Sewer Overflows How to avoid them and what to do if you don t What? Where? Why? A sanitary sewer overflow (SSO) is a discharge of untreated human and industrial waste before it reaches the wastewater treatment facility. SSOs usually occur through manholes, plumbing fixtures and service cleanouts. SSOs are usually caused by grease, debris, root balls, or personal hygiene products blocking the sewer lines, or by unusually high flow volume. How to prevent SSOs: when clearing plugged sewer laterals: Remove root balls, grease blockages and any other debris from the sewer If you can t prevent root balls, grease or debris from entering the sewer main, call us at (650) , so we can work with you to remove the blockage and prevent blockages further downstream Use plenty of water to flush lines. when constructing or repairing sewer laterals: Contact the Building Department at (650) or the Engineering Department at (650) for a permit and lateral specifications. Check your work area. Make sure there is no debris left in the sewer line before you backfill. Avoid offset joints, which may make sewer lines vulnerable to root intrusion and grease or debris accumulation. Properly bed your joints and don t hammer tap. If you cause or witness an SSO, immediately contact: Town of Hillsborough (650) After Hours: (650) Town of Hillsborough 1320 La Honda Road Hillsborough, CA DKF Solutions Group, LLC.

225 THE BAD NEWS Fats, Oils and Grease (FOG) will clog your pipes and may cause a sewage backup into your home or a sewer spill in the street that goes down the storm drain and into the Bay or other waterways. FOG CLOGS. THE GOOD NEWS Sewer backups and sanitary sewer overflows are preventable. Just follow these Sewer Smart Tips from Backup Buster: 1. Do not pour fats, oils and grease down the drain. Dispose of them properly. 2. Put a backflow device on your sewer cleanout if you are at risk of a sewer backflow. 3. Plant appropriate trees - but don t plant them over your sewer lateral. 4. Don t let your toilet turn on you! Be prepared for disaster. 5. Have a plan to maintain your sewer system annually. FOG CLOGS SEWER SMART FACTS 1. US EPA shows that 65% of all sewer spills are FOG-related. 2. The majority of FOG-related sewer backups and spills originate in residential areas. 3. Clogged sewer pipes can cost you lots of money and inconvenience if your sewer system backs up on your property. Grease Drop-off Centers Please check with your local sewer service provider, sanitary district or public works department for proper disposal techniques. Drop off locations in the greater Bay Area are listed on the Sewer Smart website. DON'T LET YOUR SEWER TURN ON YOU OR YOUR NEIGHBORS BACKUP BUSTER SAYS: DO NOT Pour Fats, Oils or Grease(FOG) down the drain. Visit sewersmart.org for a step-by-step guide to sewer maintenance in your home.

228 Protect Your Home from Sewage Backflows Wherever a sewer system exists, so does the potential for backflows Sewer main lines can become blocked due to roots, grease buildup or debris in the pipes. When this occurs, wastewater is stopped by the blockage and then backs up toward the first possible outlet usually a manhole. However, sometimes the outlet is a fixture or drain inside a home or business. Many backflows are relatively small and can be cleaned up quickly. Left unattended, however, they can result in significant property damage. When a wastewater backflow occurs, contact your City s Public Works Department or local sanitary district as soon as possible. Their crews locate the blockage and determine it if is in the public portion of the sewer; if it is, the crew removes the blockage. Property owners are responsible for internal plumbing and lateral pipes If a backup occurs within private internal plumbing or in the lateral pipe that connects private property to the public sewer, this is the property owner s responsibility. You should contact a licensed plumbing contractor to make repairs. A permit is usually required for sewer work outside of a building. Ordinance requires device that can help to prevent backflows on private property Most sewer backups are caused by plugged private laterals and can be corrected by the property owner or a plumber. However, some are caused by obstructions in the public sewer main and when this happens, a backflow can occur in a home or business. While this number remains low, the costs associated with clean up and repair are rising. Installing a Backflow Prevention Device (BPD) is the best way to prevent wastewater from backing up into your home or business, regardless of whether the clog is in the public sewer main or a private lateral. While the types of BPDs vary, they either fit in the lateral or on top of a cleanout. This allows the backflow to occur outside the building rather than through interior fixtures or drains. Since 1962 sewer cleanouts and BPDs are required when a structure is at risk of backflow. According to the Universal Plumbing Code (UPC), a BPD is required whenever the copy copy copy copy... Spring-loaded pop-up type BPD lowest drain or fixture on the property is less than one foot above the closest upstream manhole. It is in the property owner s best interests to install one without delay. Installation of the device is relatively simple, but must be done. Check with your sanitary district for local codes and advice or have one installed by a licensed plumbing contractor. Once installed, the device should be kept accessible and free from obstructions such as dirt or vegetation. Protect your property investment If you do not already have a BPD, we recommend that you install one or have one installed as soon as possible. Most of them can easily be installed by the home owner in a very short period of time. They are available in different models ranging in price from $5 to $75 and can be purchased at plumbing supply stores. For more information, visit our web site at or contact your local sanitary district. ABAG PLAN Corporation, 101 Eighth St., Oakland, CA

229 Town of Hillsborough Public Work Department Sewer/Street Division FOG Program BEST MANAGEMENT PRACTICES FOR FOOD SERVICE FACILITIES Implement the following work practices as each may apply to your operation to help minimize discharge of FOG wastes to the sanitary sewer system. For more information call the Source Control Program at 650/ Drain Screens. Clean drain screens on all drains in food preparation areas frequently. Dispose of food solids in trash or food waste recycling container. Dish Cleaning. Scrape or wipe fat, oil, grease and other food residue from cookware, utensils, etc., prior to dishwashing. Dispose food waste in trash or food recycling container. Use detergents, not soaps (soaps contain oil) Used Oils and Grease. Collect all used cooking oils and grease from pots, pans, and fryers and dispose in designated container for recycling. Do not dispose down drain or in trash. Spill Prevention. Use container with cover to transfer cooking oils and grease from kitchen to outdoor storage container. Empty containers before they are full to avoid spills. Spill Cleanup. Use absorbents such as cat litter or paper towels to pick up oil and grease spills before mopping. Keep spill cleanup supplies well marked and readily available. Fryers. Use absorbent paper under fryer baskets. Dispose in trash or with recycled food waste. Solid Food Wastes. Dispose of food waste in trash or food waste recycling container, not in sinks. Transfer a manageable weight to prevent spill. Use heavy duty or double clear container bags to help minimize container odors and leaks. Liquid Food Wastes. Do not dispose liquid food, milk shake syrups, batters and gravy, or other oily or fatty wastes down the drain. Use materials to absorb liquid and dispose in trash or food waste container. Food Grinder. Minimize or avoid use of food grinder, as food solids can contribute to clogged drain pipes and/or fill grease traps and interceptors. Trash and Recycling Containers. Inspect trash and recycling containers regularly for leaks and replace leaking containers promptly. Drain Cleaning Chemicals. Avoid use of emulsifiers or solvents other than typical dishwashing detergents. Use of drain cleaning chemicals is not a substitute for the required physical cleaning of grease traps and interceptors. Mats and Range Hood Filters. Dispose of oily wastewaters from cleaning operations in drain connected to grease interceptor; or use professional service that provides replacement mats and filters and cleans mats and filters at off-site location. Grease Traps and Drains. Use professional service to pump and off-haul grease trap wastes. Alternatively, collect skimmed oils, grease and food solids and dispose of properly. Employee Education. Post no Grease best practices signs in appropriate work

Follow our-step-by-step guide and visit our website at If you think your home may be at risk of a sewer backup, protect your home and install a Backflow Prevention Device (BPD). You ll find samples of BPDs on our website. For more information as to whether or not your house is at risk of a backup, visit Thanks for being Sewer Smart! Be Sewer Smart! Prevent Backups This Rainy Season Protect your home Here s how to determine if you are at risk of a sewer backup. Your home is at risk if, at its lowest level, your home is not at least one foot above the nearest upstream manhole of the sewer main. In some homes, the garage may have a floor drain that also must be assessed in relation to the nearest upstream manhole. In this photo, the gray house is at risk. The pink house may be at risk if it has a floor drain in the garage. Most likely, the house on the left is not at risk. This step-by-step property walk-through guide will help you find your sewer lateral, the sewer main and next upstream manhole to help you determine if you are at risk. Where s my lateral? 1 First of all go to the curb and look for an s stamped into the concrete.

231 It s sometimes painted green. If you can t find one, look around your property line for something marked sewer. This may look like a smaller manhole. This is where your curb cleanout is located. A cleanout may be close to your home and not at the property line. New homes and remodeled homes may have two cleanouts. You can draw a line between your cleanouts see where your lateral is between your house and curb cleanouts. This is your upper lateral. Why is that important? You don t want to plant a tree right over it or dig very deep over your lateral. Remodeled home with two cleanouts Where s the main? 2 Standing on your curb, look out into the street and find the nearest upstream manhole in front of your house. Connect it to the next nearest manhole so that the dotted line passes in front of your house. The main is located under the street at that dotted line. Where does my lateral join the main? 3 You can connect the dots between curb cleanout and the dotted line between manholes in the street. Your lower lateral is not going to connect where the manhole is, but about 5-10 yards straight out from your curb cleanout where it hits the dotted line where the main line passes your property between the manholes. Your home s upper lateral runs between the two cleanouts. Your lower lateral runs from the curb cleanout to where the main runs under the street. How do I know if my house is at risk? 4 Now that you have located where your lateral joins your sewer main, locate the nearest upstream manhole in the street. Stand on the manhole cover or stand at your house. Does your lowest elevation or basement appear to be at least 1 foot above the manhole? Compare it to the elevation of the manhole. Remember, your lowest drain may be in your garage or basement where you have plumbing. If the lowest elevation does not appear to be equal to or at least 1 foot above the manhole, you may be at risk. People who live in hilly areas, especially those on the downside of the street, are most at risk. If you are unsure, put on a Backflow Prevention Device BPD anyway per your local requirements. Cleanout with BPD Sewer Smart Tips If you live in a flat area you may have difficulty figuring out which direction the sewer flows. You can ask your plumber or call your sewer or sanitation district, located in the phone book under Government listings for wastewater utility services. If your home was built or remodeled after 1962, most local building codes require that your sewer system has a cleanout and a Backflow Prevention Device (also called a sewer relief device).

232 You can buy any of these items at your local grocery, pharmacy or hardware store. You can use brand names or generic products to make a complete kit. Toilet paper Wipes & Hand Sanitizers (choose biodegradable/disposable) Heavy duty plastic garbage bags and ties Five gallon plastic bucket with tight lid Toilet seat (optional) Deodorizing chemicals - household Chlorine bleach, camp chemicals, or quick lime Small shovel to dig outdoor latrine, if necessary Paper HUMAN WASTE labels to attach to bag Heavy Duty gloves Mask Store your sanitation kit near your other Emergency Supplies. Do not intermingle the kit and supplies. Find out more about items you need to keep your family safe at: To learn more, visit or call Backup Buster Says Don t Let Your Toilet Turn On You When a disaster strikes, your water or sewer service may become disrupted. Disposing of your own human waste could become a critical problem. It s something nobody wants to think about. Be prepared! When you can t flush your toilet, you need a Sanitation Kit.

233 What you need to do when a disaster happens: How will you handle your own waste? In the event of a disaster, water and sewer lines may be broken and handling your personal human waste becomes very important for your family s health and safety. Like all emergency plans, you will be happy you spent the time to prepare when disaster strikes. How to Handle Human Waste 1 2 If the Toilet Can t Be Used (if it is not safe to enter your bathroom) Do NOT flush the toilet. Turn off water at the house so contaminated water does not enter your water system. You can still use your indoor toilet, but do not flush it in the normal way. Remove the water from the toilet bowl (scoop into bucket). Line bowl with double bagged garbage bags to collect waste. Use a sturdy 5 gal bucket with a tight fitting lid and an optional toilet seat. Line it with a double-bagged garbage bags to collect waste. Add a deodorizing chemical (such as bleach, lime, or camp chemicals) per solid deposit or at least 2 times a day. (Follow any directions on the packaging.) Add a deodorizing chemical (such as bleach, lime, or camp chemicals) per solid deposit or at least 2 times a day. (Follow any directions on the packaging.) NOTE: Your sewer lines MAY be usable, even if your water lines are broken. In this case, you may be instructed to use a bucket to take water from an outdoor pool or pond, if available, and use it to manually flush your toilet If You Do Not Have a Plastic Bucket Dig a convenient camp latrine out in your yard away from the living area. Line it with a double-bagged garbage bags to collect waste. Add a deodorizing chemical (such as bleach, lime, or camp chemicals) per solid deposit or at least 2 times a day (Follow any directions on the packaging.) Storage of Human Waste Periodically remove the garbage bag and add 1/4 cup of unscented household bleach and seal the bag containing the waste. Store it in the same area as your household waste, away from your living space, but separate from your garbage. Do not put it in your garbage can. Human Waste Take care not to puncture the bags. Label the bag HUMAN WASTE and store out of direct sunlight. Do not ever burn human waste. Directions for Proper Disposal of Waste and When to Begin Using Your Toilet Listen for public service announcements about conditions in YOUR neighborhood KNBR 680/1050, KQED/NPR 88.5 or KGO 810, KCBS 740 and KLIV 1590.

311 Section 3: EMS Internal Auditing Key Section Terms Once your organization has established its EMS, verify its effectiveness. The process of reviewing and verifying your EMS through an internal audit is critical and key to improving your system. An EMS internal audit is a tool that your wastewater facility will use periodically to identify where things are working well and where improvements are needed. This information will help you assess how well your EMS is performing. The internal audit is a documented review of whether your organization is doing what it said it would do to manage its environmental issues and whether it is doing so effectively. An EMS internal audit is conducted by your organization s employees to determine your conformance with the ISO Standard. NOTE An EMS external audit is an EMS review conducted by an independent, third-party to determine EMS conformance, typically as means to seek third-party certification (see Section 4 for more information on third-party certification). Your EMS internal audit is a snapshot in time. It evaluates your documents, procedures, and records and reviews their implementation effectiveness and consistency. The audit looks at your facility s planned activities for meeting its objectives and targets and controlling its significant aspects. It also looks for signs of management s commitment to the environmental policy and the EMS, and awareness and competency among all your wastewater employees. Step-by-Step Guide to EMS Internal Auditing Step 1) Select and Train EMS Internal Auditors Step 2) Determine EMS Audit Scope and Frequency Step 3) Prepare Staff for Your EMS Internal Audit Step 4) Conduct an EMS Desktop Review Step 5) Conduct an EMS Internal Audit a. Hold an Opening Meeting b. Audit for EMS Conformance c. Report EMS Audit Findings Step 6) Develop a System Procedure for Conducting EMS Internal Audits Step 7) Check the EMS Internal Audit Procedure for EMS Conformance Audit Finding A discovery of lack of conformance to the requirements of an (ISO based) EMS criteria/checklist. All audit findings must be resolved as found during the internal audit or through a formal EMS process of corrective and preventative action. Corrective Actions As a result of the audit findings, corrective action reports (CARs) are assigned to all nonconformances to correct EMS deficiencies as they occur. CARs track an audit finding, assigning tasks to be completed, responsibilities, and timeframes. EMS Audit A planned and documented review performed in accordance with a documented audit procedure for the purpose of verifying, through interview and an evaluation of EMS documents and records, conformance with the applicable elements of your EMS. EMS Auditor A qualified and trained individual who conducts EMS audits. Each EMS Auditor should attend documented training that presents the requirements of a standard (e.g., ISO 14001) EMS and of your organization s EMS audit procedure and discusses their roles in an EMS internal audit. EMS Lead Auditor A qualified and trained individual who plans, organizes, and directs your organization s EMS internal audits. The EMS Lead Auditor is the leader of your EMS audit team and will report audit findings and observations to management. Section 3: EMS Internal Auditing (Phase 4) Wastewater EMS Handbook 145

312 Key Section Terms, continued Major Nonconformance A deficiency in meeting the requirements of an EMS. One or more of the 17 elements of the EMS which are not addressed (e.g., no system procedure) or implemented (e.g., a number of employees are not aware that you have an Environmental Policy). Minor Nonconformance A finding that leads to a failure to conform completely with an EMS element, but is not considered to be a breakdown in your system. (e.g., for example, a number of employees were overdue on their EMS refresher training. Observation A recognition of something done incorrectly or an area of concern. While not a major or minor nonconformance with an EMS requirement, if done correctly it could strengthen the EMS or if done incorrectly, could potentially cause a system failure. Remember to also document positive observations things you are doing well. System Procedure An EMS (ISO 14001) required document that establishes purpose, scope, roles & responsibilities, the tasks to be completed, and where and how the associated records and documents are maintained. NOTE The size of a typical EMS audit team will vary depending on the size of your facility. It is recommended that you have at least two to three qualified members on your team. This will allow you to rotate your auditors to different areas and prevent scheduling conflicts when auditors are sick or on vacation. 146 Step 1) Select and Train EMS Internal Auditors Your own qualified and trained employees are the best people to conduct an internal audit. If possible, train at least two people as EMS internal auditors, with one as the lead auditor. This will allow your auditors to work as a team. This also allows audits to take place when one auditor is unavailable. Your auditors should be objective, and not audit his/her own areas of operation or service. For example, if your wastewater lab manager is one of your internal auditors, he/she should not be auditing your laboratory operations. NOTE Your EMS internal auditors require training in order to be effective reviewers of your system. Consider a three-day EMS Audit Overview or five-day EMS Lead Auditor training conducted by EMS training organizations in your area. For training, contact a certified Registrar Accreditation Board (RAB) commercial organization in your area ( Also consult the Technical Assistance Providers (TAP) Directory or contact a Local Resource Center (LRC) in your region to find out if they offer EMS training for auditors. LRCs can be found on the PEER Center Website. Step 2) Determine EMS Audit Scope and Frequency Next, determine how often you want to conduct your internal audits and determine your audit scope. All programs and elements of your EMS should be audited every year. Audit your entire EMS at one time each year or break your review into specific elements for more frequent audits, where you would review a sampling of elements every quarter, but still audit all EMS elements within a year. To determine the scope and frequency of your EMS internal audits, consider the environmental importance of the activities and the results of your previous audits. For example, you may want to focus audit efforts on significant aspect areas and activities or your objectives and targets, as well as on the findings from your previous EMS audits. This will direct your EMS audits to the most important areas for potential improvement. Conduct internal audits quarterly to simplify the audit process and to get a quarterly check up on how your EMS is working. These quarterly audits and their results can then be reviewed in a quarterly management review.

313 A sample EMS audit scope and schedule is shown below. Review your entire EMS at least every year, beginning with a review of all EMS elements during your first internal audit. Then, consider conducting a sampling of EMS elements every quarter, as shown in the schedule below. Also, remember that your EMS internal audits can be integrated with other reviews you currently conduct (e.g., environmental, health and safety, quality, or security audits, etc.).

314 Three Lessons Learned (from wastewater facilities): 1. Make cheat sheets for your employees. For example, post significant aspects and objectives and targets in work areas and have wallet cards made of your environmental policy so that employees do not have to memorize the EMS. 2. Work with your staff s schedule so that you do not disrupt the routine of daily operations in the area you are auditing be flexible with your audit schedule. 3. Establish a well-defined audit schedule and plan. Also, use an EMS checklist. These tools will effectively prepare your EMS auditor(s) and keep your audits consistent. Step 3) Prepare Staff for Your EMS Internal Audit You ve developed an EMS internal audit scope and agreed on an audit schedule. You are ready to begin and so are your internal auditors. Your job as lead EMS auditor is to support the audit function by preparing your managers, employees, and all documents and records. All of these should be readily available to your audit team according to a prearranged audit schedule. In advance of the audit, prepare management by: Reviewing their EMS responsibilities Rehearsing the type of questions that the auditor might ask (NSF Guide Second Addition, Appendix A, pages ) Organizing and tracking corrective actions that the audit identifies. Indicating on managers calendars suggested times for the pre-audit meeting to review the audit scope, plan and schedule, and the closing meeting to share audit findings Encouraging them to be visible, involved, and available for the month of preparation preceding the registration audit Prepare employees by: Three Things to Avoid (from wastewater facilities): Emphasizing the find, fix, and prevent opportunity the audit provides Reviewing the environmental policy and confirming the role it has in employees daily activities Reviewing significant aspects, objectives and targets with relevant department managers and folks on the front-line 1. Trying to be too textbook and/or using too much EMS jargon during the internal audits. Your internal auditors should take what they know and relate it to the activities that are being reviewed then tie in the EMS requirement. 2. Not providing the necessary training for your internal auditors. Make sure your auditors understand the EMS and ISO requirements AND what you are trying to accomplish with your internal audits (i.e., environmental improvement). 3. Not preparing staff for your EMS Audits all employees should understand what is expected of them during an EMS internal audit. Rehearsing the types of questions that an auditor might ask them (you may want to use the checklist you developed in the internal audit) Reviewing EMS roles and responsibilities Prepare documents and records by: Ensuring they are current, easily retrievable, and controlled according to your document control procedures For sample EMS Audit Checklists, Plans, and an Audit Report Template from wastewater facilities, see Appendix B. 148 Section 3: EMS Internal Auditing (Phase 4) Wastewater EMS Handbook
