Staff has updated the SSMP in response to the State Water Resources Control Board’s amended Sanitary Sewer System Waste Discharge Regulations, which became effective on September 9, 2013. Staff further recommends that the Council designate four Utilities Department employee classifications, the Assistant Director of Utilities Operations, Water Gas Wastewater Operations Manager, Utilities Compliance Manager and Wastewater Collections Supervisor, as Legally Responsible Officials (LRO) for purposes of managing and certifying the City’s sanitary sewer system operations to the State Board. BACKGROUND On May 2, 2006 the State Board adopted the Statewide General Waste Discharge Requirement (WDR) and Monitoring and Reporting Program (MRP) to regulate wastewater collection system management. The WDR applies to all public collection system agencies in California that own or operate collection systems with more than one mile of pipe, or sewer lines that convey untreated wastewater to a publicly owned treatment facility. One of the requirements of the WDR is that each covered agency prepare, certify and implement an SSMP. On July 26, 2013 the State Board’s Executive Director issued revised MRP requirements that became effective on September 9, 2013. These changes have been developed over the past three years with input from regulated agencies and professional organizations and are based on six years of State Board Enforcement Office field inspections of collection systems throughout the State. Some of the changes in the MRP include: City of Palo Alto Page 2 1. Reducing SSO notification requirements to a single call to the Office of Emergency Services for SSOs greater than 1000 gallons. 2. Requiring a new Water Quality Monitoring Plan and Technical Report for SSOs greater than 50,000 gallons. 3. Streamlining the information that must be reported to the State SSO system for small and medium SSOs. 4. Requiring enhanced recordkeeping for SSO events. 5. Requiring an agency to maintain an up-to-date list of Legally Responsible Officials. 6. Eliminating the reporting requirement for SSOs on private sewer laterals. 7. Adding a 120-day time limit for amending and recertifying SSO reports. These new regulations required staff to make substantial changes to the City’s July 2009 SSMP. The attached revised SSMP addresses the new MPR requirements and includes recommendations by City staff and the City’s Sanitary Sewer Support consultant to comply with requirements from the San Francisco Regional Water Quality Control Board Collection System Inspection Report of June 2012. The WDR requires the City to certify that the SSMP is in compliance with the WDR every five years or when significant updates to the SSMP are made. The SSMP must be presented to the City Council at a public meeting and formally adopted to assure that the public has the opportunity to comment on the collection systems policies and procedures as identified in the SSMP. The WDR also requires the designation of technically qualified and experienced persons to ensure that the SSMP is developed and implemented appropriately and to assure controlled and secure entry to the State SSO database. The regulations require the appointment of LROs who must certify all information submitted in the SSO reporting system. Currently, the Water Gas Wastewater Operations Manager is the LRO. Because LROs must be available around the clock, staff recommends that additional job classifications be designated LROs to assure continuous coverage. In addition, the WDRs require SSMP Program Audits at least every 2 years, with a report. Plus, the SSMP must be updated at least every 5 years and recertified by Council when significant updates are made. DISCUSSION The SSMP describes the City’s wastewater collection system management activities, and meets the requirements of the State’s WDR and the City Wastewater Treatment Plant’s National Pollution Discharge Elimination System (NPDES) 2009 permit. The intent of the SSMP is to City of Palo Alto Page 3 implement a formalized rehabilitation, operation, and maintenance program for the City’s sanitary sewer collection system. Effective management of a sanitary sewer collection system includes: 1. Maintaining or improving the condition of the collection system infrastructure to provide reliable service. 2. Cost-effectively minimizing the infiltration/inflow (I/I) of groundwater and providing adequate sewer capacity to accommodate additional flows due to storm events. 3. Minimizing the number and impact of sanitary sewer overflows (SSOs). The required elements of the SSMP are as follows: ELEMENT DESCRIPTION 1 SSMP GOALS 2 ORGANIZATION INCLUDING SSO REPORTING CHAIN OF COMMAND 3 LEGAL AUTHORITY TO OPERATE AND MAINTAIN CITY’S WASTEWATER COLLECTION SYSTEM 4 OPERATION AND MAINTENANCE OF THE WASTEWATER COLLECTION SYSTEM 5 DESIGN AND PERFORMANCE OF THE WASTEWATER COLLECTION SYSTEM 6 OVERFLOW EMERGENCY RESPONSE PLAN 7 FATS, OILS AND GREASE (FOG) PROGRAM 8 SYSTEM EVALUATION AND CAPACITY ASSURANCE PROGRAM 9 MONITORING, MEASUREMENTS AND MODIFICATIONS PLAN 10 SSMP AUDITS 11 COMMUNICATION PROGRAM RESOURCE IMPACT In addition to ensuring proper planning for sewer system rehabilitation and capacity management, the Utilities Department’s Engineering and Operations Divisions will continue to rehabilitate 20,000 – 30,000 linear feet of pipe every year through the Council approved Capital Improvement Project (CIP) budget. These funds will continue to be used to meet the requirements of the SSMP as well. Wastewater Operations will continue to operate and City of Palo Alto Page 4 maintain the collection system and those approved budgets and efforts will be focused on meeting and implementing the plan elements. Any increased efforts in the operations and maintenance of the collection system identified by the SSMP may require increases to staffing levels or CIP budget proposals for Council consideration. POLICY IMPLICATIONS This request does not represent a change in policy. ENVIRONMENTAL REVIEW Council’s adoption of the revised SSMP and designation of additional employee classifications as LROs does not meet the California Environmental Quality Act’s definition of a project, pursuant to Public Resources Code Section 21065, thus environmental review is not required.

The City owns and operates approximately 216.9 miles of gravity wastewater collection system pipeline that ranges from 6 to 72 inches in diameter, 900 feet of ten inch diameter force main, approximately 3,494 manholes and one sewage lift station. The inventory of sewer lines by size is presented in the Table I-1 below. The City also owns and maintains the lower portion of approximately 21,990 lateral service connections that serve residents and businesses within the City limits. The upper service laterals, from the cleanout or property line, are owned and maintained by the individual private property owners. The City’s wastewater is treated at the Regional Water Quality Control Plant that is operated by the City of Palo Alto in partnership with the City of Mountain View, City of Los Altos, East Palo Alto Sanitary District, Town of Los Altos Hills and Stanford University. In addition to the City of Palo Alto’s collection system, wastewater is conveyed to the Plant from several sewage collection systems operated by and serving the Cities of Los Altos and Mountain View, the Town of Los Altos Hills, the East Palo Alto Sanitary District. Each of these municipalities, districts, and unincorporated areas of Stanford University campus are obligated by agreement or contract, to operate, maintain, and improve its collection system to ensure no adverse impacts to the Plant. The Cities of Mountain View and Los Altos entered into a Joint Sewer Agreement with the City of Palo Alto in 1968, with the remaining communities serving as sub-partners in other agreements. Each satellite collection system is responsible for an ongoing program of maintenance and capital improvements for sewer lines and pump stations within its respective jurisdiction in order to ensure adequate capacity and reliability of the collection system. The responsibilities include managing overflows, controlling inflow and infiltration (I&I) and implementing collection system maintenance. Each satellite collection system must ensure that its wastewater does not adversely impact the Discharger’s treatment plant.

The purposes of these activities are to: 1. Maintain and improve the condition of the collection system infrastructure, 2. Control infiltration/inflow (I/I) and provide appropriate sewer capacity, and to 3. Minimize the number and impact of sanitary sewer overflows (SSOs) that occur. The State Water Resources Control Board (SWRCB) has issued statewide waste discharge requirements for sanitary sewer systems, which include requirements for development of an SSMP. The State Water Board requirements are outlined in Order No. 2006-0003-DWQ, Statewide General Waste Discharge Requirements for Sanitary Sewer Systems, dated May 2, 2006 (SSO WDR), and amended by Order No. 2013- 0058-EXEC, dated July 30, 2013. In addition, the City’s NPDES Permit, No. CA0037834 incorporates the requirements to comply with the SSO WDR by reference in the treatment plant permit to operate Order No. R2-2009-0032 that regulates the Palo Alto Regional Water Quality Control Plant and City of Palo Alto’s sewage collection system. This SSMP is organized by the SWRCB outline of elements; and contains quoted language taken from the SSO WDR and shown in the gray box at that beginning of each element. The SSO WDR uses the term “Enrollee” to mean each individual municipal wastewater agency that has completed and submitted the required application for coverage under the WDR (in this case, the Enrollee is the City of Palo Alto). The City’s waste discharger identification number (WDID) in the California Integrated Water Quality System (CIWQS) is 2SSO10164. Regulatory Requirements The City of Palo Alto’s SSMP contains 11 elements and is designed to meet the SSO WDR requirements and the City’s 2009 Treatment Plant NPDES Permit. The structure of this document follows the section numbering and nomenclature specified in the SSO WDR. In addition, the policies and procedures of this SSMP are consistent with the deliverables required pursuant to the two Notices of Violation issued by the RWQCB on September 30, 2011 and October 4, 2012. SEWER SYSTEM MANAGEMENT PLAN GOALS 4 Element 1. Goals SWRCB Waste Discharge Requirement: The goal of the Sewer System Management Plan (SSMP) is to provide a plan and schedule to properly manage, operate, and maintain all parts of the sanitary sewer system. This will help reduce and prevent SSOs, as well as mitigate any SSOs that do occur. In August 2006, the City of Palo Alto developed the SSMP goals based on the RWQCB’s order dated July 7, 2005. Revisions to this section were made in May 2009 and August 2013 to address the subsequent SSO WDR requirements, including the revised Monitoring and Reporting Program (MRP) effective September 9, 2013. The goals of the City of Palo Alto SSMP are to:  Properly manage, operate and maintain the wastewater collection system.  Develop and maintain design construction standards and specifications for the installation and repair of the collection system and its associated infrastructure.  Cost effectively minimize infiltration/inflow (I/I) and provide adequate system capacity to handle peak flows during a storm event.  Respond to sanitary sewer overflows quickly and mitigate the impact of the overflow to public and environmental health.  Implement a collection system maintenance program to minimize sanitary sewer overflows.  Provide regular training for WGW staff and contractors in collection system maintenance and operations and emergency response.  Provide Standard forms for various tracking/reporting compliance requirements. SEWER SYSTEM MANAGEMENT PLAN Organization 5 Element 2. Organization SWRCB Waste Discharge Requirement: The Sewer System Management Plan (SSMP) must identify: a. The name of the responsible or authorized representative as described in Section J of this Order. b. The names and telephone numbers for management, administrative, and maintenance positions responsible for implementing specific measures in the SSMP program. The SSMP must identify lines of authority through an organization chart or similar document with a narrative explanation; and c. The chain of communication for reporting SSOs, from receipt of a complaint or other information, including the person responsible for reporting SSOs to the State and Regional Water Board and other agencies if applicable (such as County Health Officer, County Environmental Health Agency, Regional Water Board, and/or State Office of Emergency Services (OES)). 2.1.

Chain-of-Communication for Reporting and Responding to SSOs In response to an SSO event, Water Gas Wastewater immediately implements its Sanitary Sewer Overflow Emergency Response Plan (OERP), discussed in detail in Element 6. The OERP provides direction for the immediate verbal and written notification of City staff and OES. The initial notification of a blockage or SSO from the public is through the City’s 24-hour Dispatch Center. SSO-related calls received by other City departments are routed to the Dispatch Center for proper documentation and tracking. The Dispatch Center is responsible for routing the calls to the Emergency Response Notification Team. SSO’s observed by City Utilities Staff in the course of their normal duties are also reported immediately to the Dispatch Center and the WGW Operations Office Staff, if feasible. During the response time, the dispatcher is in communication with the responding team to ensure each call is being routed to the appropriate supervisor or other supporting team. The Dispatch Center records communications between the callers, the responders and any other supporting team that is being dispatched to the SSO scene. Important phone numbers for City staff involved in SSO response are shown on Table 2-2.

Legal Authority SWRCB Waste Discharge Requirement: Each Enrollee must demonstrate, through sanitary sewer system use ordinances, service agreements, or other legally binding procedures, that it possesses the necessary legal authority to: a. Prevent illicit discharges into its sanitary sewer system (examples may include I/I, storm water, chemical dumping, unauthorized debris and cut roots, etc.); b. Require that sewers and connections be properly designed and constructed; c. Ensure access for maintenance, inspection, or repairs for portions of the lateral owned or maintained by the Public Agency; d. Limit the discharge of fats, oils, and grease and other debris that may cause blockages, and e. Enforce any violation of its sewer ordinances. 3.1. Legal Authority The Palo Alto City Council has the power to enact ordinances and other legally binding instruments to regulate usage and prevent discharges to the sewer, including but not limited to fats, oils, grease and debris that may cause blockages. The City has approved and adopted the Sewer Use Ordinance (Palo Alto Municipal Code, PAMC, Title 16, Chapter 16.09), the Utilities Rules and Regulations, and the Utility Standards to govern the collection, maintenance, and construction of the wastewater facilities within the City. In addition, the City has entered into several agreements with its partner agencies to the RWQCP that obligates those agencies to comply with both City requirements and the WDR and NPDES permit. The specific purpose of the City’s Sewer Use Ordinance is to prevent the discharge of any pollutant into the sewer system, the storm drain system, or surface waters, which would: 1. Obstruct or damage the collection system; 2. interfere with, inhibit or disrupt the Palo Alto Regional Water Quality Control Plant or its treatment processes; 3. pass through the treatment system and contribute to violations of the regulatory requirements placed upon the plant; or 4. result in or threaten harm to or deterioration of human health or the environment. The Utilities Rules and Regulations, approved and adopted by resolution of the City of Palo Alto City Council, govern the business operation of the City’s utilities, including access, maintenance and inspection of City-owned laterals. The Utility Standards govern the requirements for proper design, construction, and maintenance of water, gas, and wastewater utility facilities and connections within the City of Palo Alto. SSMP Element 5 contains greater detail regarding the Utility Standards governing the design and construction of sanitary sewer systems. SEWER SYSTEM MANAGEMENT PLAN Legal Authority 12 Enforcement provisions are found in the Palo Alto Municipal Code (PAMC). Violations of the PAMC can be addressed through criminal, judicial, administrative, and/or injunctive action. The City may assess monetary fines as well. 3.2.

Provisions in the 2005 Partners Agreement requires that the agencies adopt companion ordinances and regulations to assure no upset or damaging conditions will affect the RWQCP in the partner wastewater discharges. The City and partner agencies meet and discuss various issues on a regular basis. Each partner agency is responsible for its own collection operations maintenance and regulatory compliance. SEWER SYSTEM MANAGEMENT PLAN Operation and Maintenance Program 14 Element 4. Operation and Maintenance Program SWRCB Waste Discharge Requirement: The Sewer System Management Plan (SSMP) must include those elements listed below that are appropriate and applicable to the Enrollee’s system: a. Maintain an up-to-date map of the sanitary sewer system, showing all gravity line segments and manholes, pumping facilities, pressure pipes and valves, and applicable storm water conveyance facilities; b. Describe routine preventive operation and maintenance activities by staff and contractors, including a system for scheduling regular maintenance and cleaning of the sanitary sewer system with more frequent cleaning and maintenance targeted at known problem areas. The Preventative Maintenance (PM) program should have a system to document scheduled and conducted activities, such as work orders; c. Develop a rehabilitation and replacement plan to identify and prioritize system deficiencies and implement short-term and long-term rehabilitation actions to address each deficiency. The program should include regular visual and TV inspections of manholes and sewer pipes, and a system for ranking the condition of sewer pipes and scheduling rehabilitation. Rehabilitation and replacement should focus on sewer pipes that are at risk of collapse or prone to more frequent blockages due to pipe defects. Finally, the rehabilitation and replacement plan should include a capital improvement plan that addresses proper management and protection of the infrastructure assets. The plan shall include a time schedule for implementing the short- and long-term plans plus a schedule for developing the funds needed for the capital improvement plan; d. Provide training on a regular basis for staff in sanitary sewer system operations and maintenance, and require contractors to be appropriately trained; and e. Provide equipment and replacement part inventories, including identification of critical replacement parts. 4.1. Sanitary Sewer System Mapping 4.1.1. Mapping The City of Palo Alto uses Geographic Information System (GIS) technology to create, maintain, and manage maps and data sets associated with its wastewater collection system facilities, storm drainage facilities, and force mains. Location, pipe and manhole inventory data including length, diameter, material, rim/invert elevations, street address, and other information are maintained. Since 1995 the Utilities Wastewater Engineering staff has maintained and utilized the City’s GIS system for the City collection system. Hardcopies of maps of the system are maintained in all service vehicles assigned to wastewater operations, offices, and in the WGW operation center. Hard copy maps are in the form of a 200-scale map book, which are in sizes of 11”x17” and 24”x16”. Updates to Existing Drawings Field crews use hard copy maps that are maintained by the Utilities Wastewater Engineering staff. Corrections are made to maps in the GIS system by Engineering staff when requested by the field staff. Hard copy versions of the full SEWER SYSTEM MANAGEMENT PLAN Operation and Maintenance Program 15 map books are provided to the Wastewater collection section by Engineering every 18 months to 2 years. Interim changes on individual pages can be downloaded from the GIS system and given to collectiion system personnel prior to the distritbution of full map books as stated above. Proposed corrections identified by field crews are delivered by electronic service orders called “SOGEN” to the Utilities Wastewater Engineering staff as field staff discovers corrections. Engineering staff makes map revisions weekly based on these orders. Storm Drains Storm drains are also shown on a GIS-based map and can be viewed by wastewater operations staff. The City Public Works Engineering staff is responsible for maintaining the storm drain map. The storm drain GIS is equipped with a tool called “FLO” that can electronically trace the location of any overflow from the source to downstream locations, including storm drains, lift station, or creeks. In addition to the GIS map, a hard copy of the City’s storm drain system map is maintained in the WGW operation center and all service vehicles assigned to the wastewater collections operation. The system map can be used to determine the routing of SSOs, in order to potentially block storm drains and contain the volume of overflows before they reach waters. 4.1.2. New Improvement Plan Drawings Upon acceptance by the City Council of all new and dedicated infrastructure, record drawings are prepared by the Engineering Division for inclusion in the GIS and sewer maps. A copy of record drawings are scanned for map updates, catalogued, and inserted into the GIS system upon installation of newly constructed and dedicated sewer mains, storm drains, and associated facilities. Drawings are submitted in both hard copy and electronic format. A scanned copy of record drawings from contractors and developers is provided to the Wastewater Collection staff so they have a record of improvements and facilities on hand prior to the publication and receipt of updated system maps. The hardcopies of records are maintained in the WGW operation center. As part of each rehabilitation and replacement project, contractors provide GPS data for sewer colleciton facilities like cleanouts, lateral connection locations, and manholes. Engineering uses this information in its updates of the GIS and wastewater collection system facilities. 4.1.3. Future Mapping Efforts The collections systems and engineering staffs meet on a monthly basis to discuss issues related to the collection system affecting both Divisions. It is recommended that the agenda for these meetings include regular discussions of mapping needs and status of updates. SEWER SYSTEM MANAGEMENT PLAN Operation and Maintenance Program 16 Addtionally, the Utilities Maintenance Division will be exploring the use and incorporation of electronic mapping and work order computer capability for all field vehicles in the near term. A change to this type of data management and electronic availability would provide the most up-to-date mapping and data for the field crews as these computer capabilities would allow for the daily updating of all changes made to maps and infrastructure data and a much more timely sharing of information with all collection system crews and would assure accurate information as the crews procede with field operations. This change would also allow the crews to electronically manage all work orders and reduce the time and effort to manage the hard copy information now used by the crews. 4.2. Preventive Operation and Maintenance The City’s wastewater collection system Operation and Maintenance Program includes proactive, preventive, and corrective maintenance of gravity sewers, and regular inspection and preventive maintenance of the lift station and force main. The details of the City’s O&M programs are described in sections 4.2 through 4.3. Figure 4-1 provides a map of the City’s sewer system service area including the Partner Agency service areas from the 2004 Wastewater Collection System Master Plan. 4.2.1. Staffing The City has twelve operation and maintenance field (O&M) employees dedicated to wastewater collection operations and maintenance. The 12 O&M field employees consist of the following positions: 4 Installer/Repairers (I/R) 3 I/R Assistants 2 I/R Leads 1 Utilities Supervisor 1 Maintenance Assistant (MA) 1 Heavy Equipment Operator (HEO) Other wastewater collection staff that support O&M include the Water Gas Wastewater Operations Manager, Wastewater Operations Supervisor, Assistant Director, Wastewater Project Coordinator, Business Analyst, Administrative Associate, Utilities Project Coordinator, Utilities Communications Manager and a Clerical Assistant. SEWER SYSTEM MANAGEMENT PLAN Operation and Maintenance Program 17 Figure 4-1: City of Palo Alto Sewer System SEWER SYSTEM MANAGEMENT PLAN Operation and Maintenance Program 18 4.2.1. Gravity Sewers The City is committed to proactively cleaning its entire collection system on a frequency of at least every 36 months with the exception of trunk lines (lines greater than 15 inches) and certain lines located in easements. Table 4-1 shows the cleaning frequencies for the various categories of lines. Pipes with historical maintenance issues like heavy FOG deposition, “hotspot” or high frequency lines, are cleaned on a preventive maintenance schedule every 3 or 6 months. The City collects and analyzes maintenance and other condition assessment data during its proactive and preventive cleaning of lines. The cleaning frequency of hotspot lines may vary and be increased seasonally, during holiday periods for example, in areas with heavy FOG deposits. In the future the frequency of sewer cleaning may be adjusted to optimize the sewer cleaning efforts based upon cleaning results as measured by the observed results in Appendix 4-2 and condition assessment by CCTV. Table 4-1: Minimum Cleaning Frequencies for Line Type Line Type Minimum Cleaning Frequency (months) Hot Spot Lines 3 - 6 Easement Lines 36 Trunk Lines (lines greater than 15 inches) 60 Siphons 36 All Other Lines 36 Figure 4-2 provides a map of the City’s sewer system and cleaning frequencies. The City uses its own staff to perform all cleaning of City collection systemlines. Gravity sewer maintenance is currently scheduled using a computerized maintenance management system called ICOMM. Maintenance activities and cleaning results are recorded in ICOMM for each segment of pipe cleaned. Work orders generated from the ICOMM system are used for the scheduling of cleaning of “Hotspot” or high frequency sewers as well as for the system-wide cleaning of all other pipes and siphons. A paper-based work order system is used to record completed work as well as work scheduling. City field staff delivers hard copies of completed work orders to Supervisors at the end of each working day. The City’s work order form used for dispatching work and recording completed work is shown in Appendix 4-1. SEWER SYSTEM MANAGEMENT PLAN Operation and Maintenance Program 19 Figure 4-2: City of Palo Alto Sewer Line Cleaning Frequencies SEWER SYSTEM MANAGEMENT PLAN Operation and Maintenance Program 20 An important aspect of the City’s sewer cleaning program is the recording of cleaning results for each manhole-to-manhole pipe segment using code-based standard results in the Standard Measures of Observed Results attached in Appendix 4-2. The results provide a basis for the Utilities Supervisor to modify the frequency or method of cleaning for that pipe segment to reflect current field conditions. Follow-up video inspections and/or repairs are requested as needed by the Utilities Supervisor to assure quality of the cleaning and for training of City employees. This process is shown in Figure 4-3. The City is currently beginning a process to define the cleaning and maintenance requirements of all system siphons that have in the past not had regular maintenance on these line segments. This program will evaluate required equipment, porocedures, frequency of evaluation and cleaning and the possible use of contractors to conduct this work when required Cleaning is presently performed on a basin based approach utilizing fourteen (14) basins defined in the City’s GIS. Basins are geographically located to reduce travel time to the basin and maximize crew productivity once work in the basin is initiated. Figure 4-4 contains the current Wastewater Utility Basin Map. All lines in a basin, except hot spot lines, are cleaned prior to moving to the next basin. Work orders are prepared in “routes” which include about 3,500 to 5,000 linear feet of cleaning, and are provided to field crews at the start of each day. There is usually one crew working on line cleaning daily, but sometimes there are two crews working on cleaning, depending upon work load priorities and projects. Most cleaning is accomplished by hydroflushing sewer lines, using a combination high velocity jetter/vacuum truck. The City has two of these units, both of which are anticipated to be replaced during the Summer of 2014 with similar units. A rodding machine is also used on occasions in lines that may require saws to remove roots or to break large stoppages. The City monitors technology changes in sewer cleaning tools to identify potential additions to the standard array of tools available to City collection crews. New technology will be piloted by crews to determine effectiveness of the tools to support City cleaning practices.

All line segments or “assets” were rated according to a standardized defect coding system, given a damage severity index (DSI), and catalogued in ICOMMM. The data obtained from these inspections and the ratings are used to assist in the prioritization of the City’s sewer rehabilitation and replacement program, as well as the identification of hotspot lines. Current CCTV inspections are performed by City staff via the use of a CCTV van equipped with a camera, a computer, and software (Pic-Ax) that enables video results of lines to be downloaded and maintained in the ICOMMM system. Small, portable cameras are also available for use in small diameter lines/laterals and special cases where the van system is cumbersome. Chemical Root and Grease Control Lines with a history or record of significant root intrusion, or in areas that are not readily accessible such as parks or easements, may be treated with chemicals to control root growth, on an as needed basis. City staff occasionally applies commonly used chemicals for this purpose as well as grease emulsifying agents to assist with FOG control. The City is exploring the possibility of expanding the chemical root control program utilizing City staff in the future. Manhole Inspection The City will assess the condition of the manholes and other structures using City field crews and visual inspection methods during its system-wide sewer cleaning. A sample manhole inspection form for use in collecting the condition data is included as Appendix 4-3. QA/QC The City’s Lead Installer/Repairers (I/R) provide feedback to line cleaning crews on the quality of their cleaning on approximately 2% of the footage of cleaning performed. Formal QA/QC consists of performing CCTV inspection of selected lines within 2 weeks of their cleaning by crews. The Lead I/R provides feedback to cleaning crews to support modification of cleaning processes, practices, techniques, and tool use to improve line cleaning quality. Feedback is generally given in staff meetings and in one-on-one meetings with employees. Lower Laterals/Cross-bore Program The City has responsibility for lower laterals as well as main line sewers, and initiated an aggressive lateral inspection program (“cross-bore” program) in late 2011 to determine whether there were structural and maintenance issues present in laterals resulting from gas or water service lateral construction. Findings and results from this program have triggered the replacement of hundreds of lower laterals (about 300-400 per year) and helped to prioritize the future replacement of others. The City contracts for this work, which includes cleaning and CCTV inspection of all lower laterals, and supplies two staff members to assist the contractor. This group also serves as the first responders to collection system SEWER SYSTEM MANAGEMENT PLAN Operation and Maintenance Program 24 service calls, which minimizes response time to calls and prevents taking other staff away from cleaning, assessment, and repair work. It is anticipated that this program will be completed in the summer of 2014. 4.2.2. Lift Stations The City operates and maintains one lift station. Collections Division staff perform routine operational checks of the station twice a week and the wet well is cleaned quarterly. Preventive maintenance for mechanical and electrical equipment is done annually by Utilities Maintenance. The station has an audible alarm and is connected through a SCADA system to the Utilities Dispatch Center. The station serves approximately 25 homes and a portable generator is available in the event of power outages. 4.2.3. Force Mains The City has one ten (10) inch diameter discharge force main of 900 linear feet that serves the lift station, in Foothill Park. (A force main moves wastewater under pressure by using pumps or compressors located in lift stations. They carry wastewater from lower to higher elevation).The City performs annual inspections of the force main points of discharge for visible signs of corrosion or material degradation. City staff will be initiating annual above ground visual inspections of the force main aligment for signs of problems or leakage from the force main in the coming year. 4.3 Sewer Overflow Alternative Program (SOAP) To prevent recurring SSOs, the City developed and has implemented a Sewer Overflow Alternative Program (SOAP). The program requires a follow-up review of each mainline and lower lateral SSO no later than one year after the SSO. This review is scheduled (through ICOMM) for 11 months following the SSO event. The review involves a CCTV inspection of the line or lateral in which the SSO occurred to identify maintenance requirements or need for additional repairs or replacement. Adjacent laterals may also be evaluated during inspections of lower lateral overflow locations. Many lower laterals are replaced as a result of this program. Lines and laterals that are not replaced or repaired within three years and have not experienced additional SSOs, are removed from the SOAP program. The program currently includes approximately 450 line segments and lower lateral locations. 4.4 Rehabilitation and Replacement Plan Since 1988, the City has had an ongoing Capital improvement Program (CIP) to rehabilitate and replace its sewer infrastructure. Approximately 25,000 to 30,000 feet of sewer mains are addressed each year. To date, approximately 65 miles of sewer mains have been rehabilitated or replaced, primarily by pipe bursting with high-density SEWER SYSTEM MANAGEMENT PLAN Operation and Maintenance Program 25 polyethylene (HDPE) pipe. Since 2005, the sewer rehabilitation projects have also included replacement of the associated lower laterals. Areas of the system are targeted for rehabilitation based on the results of the 2005-06 CCTV inspection work and review of SSO, line cleaning maintenance records, and SOAP program inspections. In addition, sewers may also be replaced in selected “targeted work zones” where City Public Works has planned pavement rehabilitation and improvement work scheduled. The sewer rehabilitation CIP is overseen by the Utilities Engineering Division. Other minor sewer main repair work is conducted on an as-needed basis by Utilities Operations to address sewer maintenance or structural problems identified through regular maintenance or CCTV inspection activities. 4.4.1. Gravity Sewers The City’s Rehabilitation and Replacement Program is driven by the condition of its sewer system assets as described above. In addition to main replacement, lower lateral replacements are done in response to maintenance problems, follow-up to SSO events as part of the SOAP program, and upon discovery of problems with the cross-bore program. Lateral repairs and replacements are performed by City staff as well as contractors, and approximately 400 laterals are replaced annually in addition to those replaced as part of main line replacement projects. Similar to main lines, lower laterals are generally replaced by pipe bursting with HDPE pipe. 4.4.2. Lift Station The annual inspections perfomed on the lift station serve as a basis for the preparation of a deficiencies list to be considered for inclusion in the City Capital Improvement Program. 4.4.3. Capital Improvement Program The sewer system rehabilitation and replacement projects are included in the City’s Five Year Capital Improvement Program (CIP). The annual expenditures for the City’s CIP, which totals an average of $3 million to $4 million annually for wastewater collection system rehabilitation and replacement, are shown by program in Table 4-2.

The funds that support the Capital Improvement Program come from the City’s Sewer Fund. The Sewer Fund is an enterprise fund that includes annual sewer service charges, connection fees and interest. Additional funding from the Utilities Operations operations and maintenance budget is made available for emergency repairs and lateral replacement, which is administered by Utility Operations. 4.5. Training Program The City has a revised training plan that was completed in June 2013 that includes training for City-specific issues, such as operation of its key pieces of equipment, as well as general safety and operational issues, the SSMP and Operation Emergency Response Plan (OERP) and SSO response procedures. The City uses both contracted and in-house training services and requires training or certification of conformance of training of contractors on its OERP and SSO response procedures. 4.5.1. City Staff The City uses a combination of in-house classes, on-the-job training, conferences, seminars, and other training opportunities to provide technical training for its wastewater collection system staff. Vendors provide training for new tools or equipment. A portion of bi-weekly tailgate meetings are dedicated to training on various wastewatwer topics. These short meetings prior to the start of SEWER SYSTEM MANAGEMENT PLAN Operation and Maintenance Program 27 the day’s field work provide the opportunity for quick discussions of short topics related to specific collection system operations issues. The sources of technical training and training materials for the City’s wastewater collection staff are listed in Table 4-3 and Table 4-4.

In addition, the City provides free training and seminars on various professional development topics inclduing computer applications, writing, and communication skills. Individual training records are documented and maintained by the City’s Department of Human Resources. 4.5.2. Contractors Working on City Sewer Projects SEWER SYSTEM MANAGEMENT PLAN Operation and Maintenance Program 28 The City requires contractors working on its wastewater collection system to have been trained on the City’s Sanitary Sewer Overflow Emergency Response Plan or have demonstrated they they have been trained on an equivalent emergency response plan of their own. In addition, all City projects that may impact City collection system lines or facilities, require that the emergency procedures be discussed regularly, and especially at the pre-construction conference at the start of a project. 4.6. Equipment and Parts Inventory A summary of major tools and equipment used by staff to maintain the City’s collection system is shown in Table 4-5. The smaller tools are kept inside the service vehicles and are easily accessible to field staff. The larger tools and equipment are housed inside the City’s Municipal Service Center (MSC). The City also operates a General Store that maintains spare parts and critical operational items used by field crews. Access outside of regular working hours is limited to supervisory and senior management staff. Vehicles are housed at the City Maintenance Yard as are bypass pumps, hoses, and other items to assist in containing and mitigating SSOs.

In addition, record drawings of all final project elements must be submitted and approved by Utilities Engineering prior to final acceptance of any project on City infrastructure. 34 Element 6. Sanitary Sewer Overflow Emergency Response Plan SWRCB Waste Discharge Requirement: 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 Sewer System Management Plan (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. The components of the City’s Sanitary Sewer Overflow Emergency Response Plan are described below. 6.1. Goals of the Sanitary Sewer Overflow Emergency Response Plan The City’s goals with respect to responding to SSOs are:  Work safely;  Minimize public contact with the spilled wastewater;  Respond quickly to minimize the volume of the SSO;  Contain spilled wastewater to the extent feasible;  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;  Mitigate the impact of the SSO; and  Meet the reporting requirements in the SSS WDR.  Evaluate the causes of failure related to certain SSOs.  Revise response procedures resulting from the debrief and failure analysis of certain SSOs. SEWER SYSTEM MANAGEMENT PLAN Sanitary Sewer Overflow Emergency Response Plan 35 6.2 SSO Notification Procedures: Detection and Dispatch Utilities customers can report SSOs or sewer blockages by calling one of the following numbers: (650-329-2579), (650-329-2413) or the emergency 911 number. The phone numbers are included in monthly utility bills sent to customers and on the City’s website. SSO-related calls from the public are routed through the City’s 24-hour Dispatch Center. SSO-related calls that are received by other departments and/or observed by Utilities Staff during the course of their normal duties are also routed to the Dispatch Center for proper documentation and tracking. The SCADA alarm system for the City’s single lift station is routed through the Utilities Communication Center. The Dispatch Center is responsible for collecting the following information from all collection system related incoming calls:  Time and date of call  Incident number  Specific location of potential problem  Nature of call  In case of SSO, estimated start time of overflow  Caller’s name and phone number  Caller’s observation (e.g., odor, duration, location on property, known impacts, indication if surface water impacted, appearance at cleanout or manhole)  Other relevant information The Dispatch Center assigns a unique identification number to each call. This call number is used to track subsequent actions taken in response to the call. The Dispatch Center immediately notifies the Emergency Response Notification Team (ERNT) of a call through a Text/Email notification. The list of individuals on the ERNT is included in Table 6-1 below. The Dispatch Center’s Text/Email Notification to the ERNT consists of the following information:  Incident number  Location  Contact person  Phone number SEWER SYSTEM MANAGEMENT PLAN Sanitary Sewer Overflow Emergency Response Plan 36 Table 6-1: Text/Email for Emergency Response Notification Team Name Email Phone Javad Ghaffari javad.ghaffari@cityofpaloalto.org 650-444-6348 Bryan Hagins bryan.hagins@cityofpaloalto.org 650-438-2991 Jasen Strickland jasen.strickland@cityofpaloalto.org 650-444-6123 Jorge Silva jorge.silva@cityofpaloalto.org 650-444-8911 Todd Carlsen todd.carlsen@cityofpaloalto.org 650-444-6334 Rui Silva rui.silva@cityofpaloalto.org 650-444-6124 Jan January jan.january@cityofpaloalto.org 650-496-6982 Althea Carter althea.carter@cityofpaloalto.org 650-496-5976 Eric Talley eric.talley@cityofpaloalto.org 650-444-4002 Filiberto Castro filiberto.castro@cityofpaloalto.org 650-847-7038 Joel Gonzalez joel.gonzalez@cityofpaloalto.org 408-396-5775 Martin Simon martin.simon@cityofpaloalto.org 209-542-0465 Alicia Easton alicia.easton@cityofpaloalto.org 650-329-2271 Cross Bore N/A 650-213-2633 WGW Primary N/A 650-444-6198 WGW Secondary N/A 650-444-5290 Upon receiving the Text/Email Notification, the First Responder from the ERNT acknowledges receipt of the Text/Email Notification. Designation of the First Responder is discussed in Section 6.3. The Dispatcher remains in communication with the ERNT to ensure each call is ultimately routed to the appropriate personnel. The Dispatch Center records communications between callers, responders and any other supporting staff that is dispatched to the SSO scene. Figure 6-1 contains a flow chart of this SSO Detection and Dispatch process. Depending on the time of the call, the Dispatch Center uses the schedule shown in Table 6-2 to dispatch a response team. SEWER SYSTEM MANAGEMENT PLAN Sanitary Sewer Overflow Emergency Response Plan 37 Table 6-2: Schedule for Dispatching a Response Team Days Time SSO Response Team Weekdays* 0630-1600 Wastewater Service Crew 1600-2000 Wastewater Night Shift Crew 2000-0630 Standby Primary and Secondary Saturdays 0800-1630 Wastewater Service Crew 1630-0800 Primary or Secondary Lead Sundays & Holidays 0800-0630 Primary or Secondary Lead *On Fridays, the Wastewater Night Shift Crew receives sewer related calls starting at 1500 hours. 6.2.1. SSO Resulting from Lift Station or Force Main Failure The City of Palo Alto operates one wastewater lift station that is located in Foothill Park and serves a small community of approximately 25 customers. The station has two pumps that lift wastewater and discharges through 900 feet of 10- inch force main. The pump station is controlled by SCADA and maintained by the Utilities Operators and City Mechanics on a regular basis. In case of any pump failure, the high level sensor activates the SCADA alarm system and the Utilities Communication Center (UCC) is contacted. Under this situation, the UCC serves the role of City Dispatch by contacting the ERNT and then documenting subsequent actions taken. To prevent overflow, wastewater from the wet well can be pumped into a vacuum truck for disposal to a nearby sanitary sewer manhole as described in City SOP 3.10 and 3.11. 6.3 Designation of SSO Response Personnel 6.3.1. Acknowledgement of Text/Email Notification One of the following will be assigned to acknowledge the Text/Email Notification.  Utilities I/R  Utilities I/R Lead  Utilities I/R Assistant  Utilities Supervisor In-Charge  Wastewater Coordinator (Regular Business Hours only) More than one Utilities Operator is on a SSO Response Team. Since the lead of the team is dependent on the composition of operators, the team lead’s position title is not set. The lead of an SSO Response Team when a call comes in is designated the First Responder. If there is no acknowledgement within 10 minutes of receiving the Text/Email Notification, the next person listed is SEWER SYSTEM MANAGEMENT PLAN Sanitary Sewer Overflow Emergency Response Plan 38 contacted until acknowledgement is received and that person becomes the First Responder. 6.3.2. SSO Response Team Mobilization The designated First Responder will make contact with the Reporting Party and verify the following:  Verify that an SSO or blockage is occurring;  Determine if SSO appearance point(s) is from a manhole or cleanout or other location;  If the SSO is occurring from a cleanout, instruct Reporting Party not to use water to minimize the SSO;  If there is only a blockage in the main line, instruct Reporting Party not to use water in an attempt to prevent an actual overflow; and  Inform Reporting Party of the estimated arrival time of the City crew. After making contact with Reporting Party, the First Responder will reply to the ERNT via Text/Email to inform them that contact was made with Reporting Party and that the crew is on its way. The Dispatch Center documents this information. Figure 6-1 contains a flow chart of the process for City notification of a potential SSO.

Table 6-1 of the SSMP contains the list of individuals and contact information for the ERNT. 2. The First Responder is a designated staff member, depending on the time. If the staf member does not respond within 10 minutes, the next staff member on the ERNT list must respond and then becomes the Primary Person. SEWER SYSTEM MANAGEMENT PLAN Sanitary Sewer Overflow Emergency Response Plan 40 6.4 SSO Categories The responsibilities of the SSO Response Team depend on the volume and location of an incident. Four categories of SSOs are defined by the SWRCB: Category 1 SSO: Discharges of untreated or partially treated wastewater of any volume resulting from an enrollee’s sanitary sewer system failure or flow condition that:  Reach surface water and/or reach a drainage channel tributary to a surface water; or  Reach a municipal separate storm sewer system and are not fully captured and returned to the sanitary sewer system or not otherwise captured and disposed of properly. Any volume of wastewater not recovered from the municipal separate storm sewer system is considered to have reached surface water unless the storm drain system discharges to a dedicated storm water or ground water infiltration basin (e.g., infiltration pit, percolation pond). Category 2 SSO: Discharges of untreated or partially treated wastewater of 1,000 gallons or greater resulting from an enrollee’s sanitary sewer system failure or flow condition that do not reach surface water, a drainage channel, or a municipal separate storm sewer system unless the entire SSO discharged to the storm drain system is fully recovered and disposed of properly. Category 3 SSO: All other discharges of untreated or partially treated wastewater resulting from an enrollee’s sanitary sewer system failure or flow condition. Category 4 SSO - Private Lateral Sewage Discharge: Discharges of untreated or partially treated wastewater resulting from blockages or other problems within a privately owned sewer lateral connected to the enrollee’s sanitary sewer system or from other private sewer assets. PLSDs that the enrollee becomes aware of may be voluntarily reported to the CIWQS Online SSO Database. 6.5. SSO Response by Category SSO response activities are organized by the SWRCB defined SSO categories. SSO response time, determined as the difference in time from the incoming service call to arrival at the site, is typically 20 minutes during regular business hours and up to one hour after regular working hours. 6.5.1. Category 1 Response Upon arrival at the incident site, the response crew does the following: 1. Documents arrival time at the incident site; SEWER SYSTEM MANAGEMENT PLAN Sanitary Sewer Overflow Emergency Response Plan 41 2. Determines cause of the overflow; 3. Protects storm drain by placing mat, dam, or gel barrier around pertinent storm catch basin(s) or otherwise provide containment to limit the extent of the SSO; 4. Determines if the overflow or blockage is from a public or private sewer; 5. If private property is impacted, calls the Utilities Supervisor; 6. First Responder contacts Utilities Supervisor to notify him/her that the overflow has reached a storm drain, drainage channel or surface water and is not fully recoverable (see Section 6.6 for Category 1 Regulatory Notification); 7. If feasible, photographs the location of the incident and any affected areas; 8. Takes immediate steps to protect public health, relieve the blockage, provide traffic and crowd control, if necessary, around the affected spill area; 9. Posts raw sewage signs, as necessary;(Appendix 6-1); 10. If necessary, contacts the Utilities Supervisor to request additional personnel, materials, supplies, or equipment that will expedite and minimize the impact of the overflow; 11. References the storm drain collection system map to identify and block the downstream storm drain so that the wastewater can be collected from the storm drain; 12. Collects wastewater and debris from the site and storm drain and if possible, returns the wastewater to the collection system; 13. Disinfects the affected area and mitigates all other impacts of the SSO; and 14. First Responder collects and documents all event information on the City’s Main/Lateral Overflow Report Form WGWO_500. The Utilities Supervisor is responsible for determining the proper course of action for Category 1 SSOs. The Utilities Supervisor will utilize the wastewater collection system map, storm drain collection system map and other documentation to minimize the impact of the overflow to the environment and protect public health. If an SSO is confirmed to have entered a creek or waterway, the Utilities Supervisor and the Operations Manager are immediately notified. The Utilities Supervisor may request additional assistance, if needed, from City staff and/or outside agencies that are the wastewater treatment plant partners (City of Mountain View, City of Los Altos, Town of Los Altos Hills, Stanford University and the East Palo Alto Sanitary District). The SSO Response Team is responsible for the following:  Determines the extent of the SSO by investigating downstream until there is no evidence of sewage or debris along the creek or water body;  Contact the Public Works, Environmental Services Division, Watershed Protection Group (during business hours only) for technical assistance with water quality sampling; SEWER SYSTEM MANAGEMENT PLAN Sanitary Sewer Overflow Emergency Response Plan 42  Immediately post contaminated water sign(s) and protect the creek from public access on both sides (Appendix 6-2);  Photographs sign placement and evidence of the overflow in and around the creek to the farthest point reached by the sewage;  Determines if the creek is safe to enter. During the winter storm season, cleaning the creek may not be feasible due to high water flows;  If feasible, blocks the creek downstream of the affected area in a location that is safe to enter and is accessible to set up a pump or utilize VacCons;  To extent feasible, recovers and returns contaminated water to the collection system;  If the SSO is 50,000 gallons or greater, collects water quality samples within 48 hours of becoming aware of the SSO. Samples must be collected in accordance with the Spill Sampling Procedures published by the Watershed Protection Group (Appendix 6-3);  Follow up sampling will be performed until the area shows no water quality impairment and the posted signs can be removed. The Utilities Director ultimately determines when this happens and makes any follow up calls to affected agencies. 6.5.2. Category 2 Response Upon arrival at the incident site, the response crew does the following: Steps 1 through 14, noted above except step 6, which is to notify the Utilities Supervisor In-Charge that the overflow has reached a storm drain, drainage channel or surface water and is not fully recoverable. Instead, if the overflow appears to exceeds 1,000 gallons, reached the storm drain and cannot be fully recovered, or has the potential to reach waters of the US, the First Responder notifies the Utilities Supervisor so that proper notification can be made to OES within 2-hours of becoming aware of the overflow. 6.5.3. Category 3 Response Upon arrival at the incident site, the response crew does the following: Steps 1 through 14, noted above except step 6, which is to notify the Utilities Supervisor in charge that the overflow has reached a storm drain, drainage channel or surface water and is not fully recoverable. 6.6. 2 Hour Notification to Regulatory Agencies of SSOs The State Water Resources Control Board Order No. 2006-0003 states that the Office of Emergency Services (OES) is only to be notified of a Category 1 SSO greater than or equal to 1,000 gallons discharged to surface water or spilled in a location where it probably will be discharged to surface water. The Utilities Supervisor is responsible for reviewing field data for reporting to regulatory agencies (Figures 6-2). If it is determined SEWER SYSTEM MANAGEMENT PLAN Sanitary Sewer Overflow Emergency Response Plan 43 that the criteria for OES notification was met, than the Utilities Supervisor must notify OES of the event no later than two (2) hours after: a) The City has knowledge of the SSO; b) notification is possible and c) notification can be provided without substantially impeding cleanup or other emergency measures. The OES phone number is (800) 852-7550. The Utilities Supervisor is responsible for obtaining an OES Control number. Following the initial notification to OES and until the SSO report is certified in the SWRCB online SSO Database, the Utilities Supervisor must provide updates to OES regarding substantial changes to estimated volume of untreated or partially treated sewage discharged and any substantial changes to known impact(s). 6.7. Media Notification Procedure When an overflow is substantial and confirmed to be a significant public health threat, the following actions should be taken, if deemed necessary by city staff, to notify the media: 1. The Utilities Supervisor or the Operations Manager will contact the Utilities Communications Manager (UCM) to provide her/him with a SSO status report. 2. The status report must include; time, location, volume of SSO, health and safety concerns, road and/or facility closures and any other relevant information. 3. The CSM is responsible for contacting and updating the media. 4. Any calls from the media should be routed to the CSM. 5. The following personnel are authorized to release information on the incident and be interviewed by the media and are the designated spokespersons: Staff Position Contact Name Office Phone Mobile Phone Utilities Communications Manager (UCM) Katz, Debbie 650-329-2656 408-691-4225 Utilities Assistant Director Batchelor, Dean 650-496-6981 408-891-7064 SEWER SYSTEM MANAGEMENT PLAN Sanitary Sewer Overflow Emergency Response Plan 44 Figure 6-2: Regulatory Notification and Reporting Flowchart Did the SSO discharge to a drainage channel and cannot be fully recovered or did the SSO discharge to surface water? This is a Category 3 SSO. Submit a certified report to CIWQS2 within 30 calendar days of the end of the month in which the SSO occurred. NOTES: 1. Notification Phone Script: "This is (name) from the City of Palo Alto. There has been a sanitary sewer overflow that requires notification to OES. The overflow occurred at (date, time, location) and the estimated amount of the overflow is (# of gallons). A city crew was dispatched and on site at (time) to alleviate the stoppage and mitigate impacts." Make sure you obtain a OES control number for the call. Also, note if surface water was impacted and a spill rate, if applicable. 2. Report SSOs to CIWQS at http://ciwqs.waterboards.ca.gov/. This is a Category 1 SSO that requires 2-hour Notification to the State of Emergency Services (OES). Call: 800-852-7550 and use the phone script1. YES NO Is the SSO estimated to be 1,000 gallons or greater? YES This is a Category 1 SSO that does not require 2-hour Notification. NO NO This is a Category 2 SSO. Is the SSO greater than or equal to 1,000 gallons discharged to surface water or spilled in a location where it probably will discharge to surface water? Submit a draft report to CIWQS2 within three business days of becoming aware of the SSO and certify within 15 calendar days of SSO end date. Was the SSO caused by a blockage on private property? NO This is a Private Lateral Sewage Discharge. Contact the Utilities Supervisor In- Charge. YES YES START Continue Continue Continue Is the SSO ≥ 50,000 gal and reach surface water? NO Done. YES Water quality sampling required within 48 hrs of becoming aware of the SSO. In addition, submit an SSO Technical Report to CIWQS2 within 45 calendar days of the SSO end date. See SSS WDR MRP Section B.5 SEWER SYSTEM MANAGEMENT PLAN Sanitary Sewer Overflow Emergency Response Plan 45 6.8. SSO Documentation and Recordkeeping The Utilities Supervisor is responsible for reviewing and approving all field documentation pertaining to the SSO event. He/she completes an SSO Checklist to ensure proper documentation is compiled for each SSO record. Appendix 6-4 contains the SSO Checklist. The original, hard copy of all SSO related documents, including volume estimations and photographs, are maintained in the City of Palo Alto Municipal Service Center (MSC) for a minimum of 5 years from the date of the event unless otherwise directed by the RWQCB or SWRCB. If an SSO volume is 500 gallons or greater, all records for that event are stored in a separate folder with the OES event number, date and location of SSO. SSO records less than 500 gallons are compiled and stored in a single folder by month of occurrence. Both forms of SSO documentation are located in a single area in the MSC. The nature of the incident dictates what field form the crew uses to document field activities. If the blockage does not result in an overflow, the crew fills out the Sewer Main/Lateral Overflow Stoppage Report Form WGWO_501. If the blockage results in an overflow, the crew fills out the Sewer Main/Lateral Overflow Report (SSO compliance) Form WGWO_500. Appendix 6-5 and 6-6 contains the current SSO field forms WGW0_500 AND 501. ICOMMM, the City’s maintenance management system, documents all other sewer service calls through a work order system. 6.9. SSO Reporting 6.9.1. Multiple Appearance Points – Single SSO For reporting purposes, if one SSO event of whatever category results in multiple appearance points in a sewer system, a single SSO report is required in CIWQS which includes the GPS coordinates for the location of the SSO appearance point closest to the failure point, blockage or location of the flow condition that caused the SSO, and descriptions of the locations of all other discharge points associated with the single SSO event. 6.9.2. SSO Reporting for Category 1 OES shall receive notification of Category 1 SSOs greater than or equal to 1,000 gallons, as stated previously in Section 6-4. The Supervisor (Data Submitter) must then submit the initial draft report to the SWRCB’s CWIQS Online SSO database @ http://ciwqs.waterboards.ca.gov/ciwqs within 3 business days of becoming aware of the SSO SEWER SYSTEM MANAGEMENT PLAN Sanitary Sewer Overflow Emergency Response Plan 46 Within 15 calendar days of the SSO end date, the Utilities Operation Manager or other designated LRO (LRO) must review and certify the report in the CWIQS Online SSO database @ http://ciwqs.waterboards.ca.gov/ciwqs At minimum, the following mandatory information shall be reported prior to finalizing and certifying an SSO report: Draft Category 1 SSO: 1.

SSO Reporting for Private Lateral Sewage Discharges Private lateral sewage discharges (PLSD) from an upper sewer lateral that the City becomes aware of or responds to may be voluntarily reported in the CIWQS online SSO database. If the overflow is determined to be caused by a blockage in the City main that then appears from the upper sewer lateral, this overflow is a City SSO and must be reported as such. Only overflows from the upper sewer lateral that are caused by the private property owner are PLSDs. The Collections Supervisor reporting the PLSD must specify that the sewage discharge occurred and was caused by a private line and identify the responsible party, if known. No LRO certification is required for PLSDs. 6.9.6. SSO Technical Report If 50,000 gallons or greater from an SSO reaches surface waters, an SSO Technical Report must be prepared and submitted to the CIWQS online SSO database within 45 calendar days of the SSO end date. The SSO Technical Report must include, at a minimum, the following: i. Causes and Circumstances of the SSOs; a. Complete and detailed explanation of how and when the SSO was discovered. b. Diagram showing the SSO failure point, appearance point(s), and final destination(s). c. Detailed description of the causes(s) of the SSO. d. Copies of the original field crew records used to document the SSO. e. Historical maintenance records for the failure location. ii. Response to SSO: a. Chronological narrative description of all actions taken to terminate the SSO. b. Explanation of how the OERP was implemented to respond to and mitigate the SSO. c. Final corrective action(s) completed and/or planned to be completed, including a schedule or actions not yet completed. iii. Water Quality Monitoring a. Description of all water quality sampling activities conducted including analytical results and evaluation of the results. b. Detailed location map illustrating all water quality sampling points. SEWER SYSTEM MANAGEMENT PLAN Sanitary Sewer Overflow Emergency Response Plan 49 The Operations Manager or other designated LRO is responsible for the development and certification of the SSO Technical Report . 6.9.7. No Spill Certification (Monthly) Within 30 calendar days of the end of a calendar month that there are no SSO’s, the Wastewater Collections Supervisor must submit and the Utilities Operations Manager must certify a “No Spill” certification to the CIWQS online SSO database. 6.9.8. CIWQS Not Available In the event that the CIWQS online SSO database is not available, the Wastewater Collection Supervisor will fax or e-mail all required information to the RWQCB office at (510) 622-2460 in accordance with the time schedules identified above. In such an event, the City will submit the appropriate reports using the CIWQS online SSO database when the database becomes available. A copy of all documents that certify the submittal in fulfillment of this section shall be retained in the SSO document file. 6.9.9. Amending SSO Reports A City LRO is responsible for amending SSO reports. Certified SSO reports may be updated by amending the report or adding an attachment to the SSO report within 120 calendar days after the SSO end date. After 120 days, the City must contact the State SSO Program Manager to request to amend an SSO report along with a justification for why the additional information was not available prior to the end of the 120 days. The SSO Program Manager contact information follows: Russell Norman, P.E. State Water Resources Control Board Division of Water Quality 1001 I Street 15th Floor Sacramento, CA 95814 E-mail: Russell.norman@waterboards.ca.gov Phone: (916) 323-5598 6.9.10. Internal Reporting SSOs related to FOG If an SSO is determined to be caused by FOG, either from one or more food service facilities or specific residential areas, the Utilities I/R Lead will complete and transmit an ICOMMM work order to the City’s FOG Manager, Environmental SEWER SYSTEM MANAGEMENT PLAN Sanitary Sewer Overflow Emergency Response Plan 50 Control Program, located at the Regional Water Quality Control Plant (RWQCP). The work order includes the following information, at minimum:  Location of affected laterals, manholes and sewer main segments  Date, time, address, and cause of the SSO  Severity of the FOG  If available, a copy of the CCTV or a statement when it will be available The work order is subsequently returned to Utilities as a means of assuring the information was integrated into the FOG Program. 6.10 SSO Failure Analysis 6.10.1. Post-SSO Debriefing For each SSO event greater than 250 gallons, all participants involved in the response – from the person who received the call to the last person to leave the site – should meet, as soon as feasible, after the event to review and evaluate the incident and the City response procedures. The objective of the Post-SSO Debrief is to determine actions necessary, if any, to reduce the recurrence and better mitigate the effects of SSOs. The results are documented and tracked on a Post-SSO Debrief form to ensure the identified action items are implemented. The Post-SSO Debrief Form is located in Appendix 6-7. The Post-SSO Debrief documentation is filed in the final SSO file for the incident. 6.10.2. SSO Investigation and Mitigation It is the responsibility of the Utilities Supervisor in charge of Wastewater Operations/Utilities Supervisorto investigate an SSO and to ensure that the procedures in the OERP are followed or modified as a result of the incident failure analysis. The Wastewater Supervisor failure analysis is intended to determine if additional maintenance, repair/replacement or other follow-up actions or response procedures changes are needed to reduce or eliminate the likelihood of future SSOs. The procedures for investigating an SSO are as follows:  Review the incident/overflow report (WGWO_500).  Interview dispatch, first line supervisor, primary person, field service representatives, customers service representatives (if used) responding crew members or any other agency staff that were involved with the response.  Review the incident timeline and other documentation regarding the incident.  Review communications with the Reporting Party and witnesses.  Review photographs of the incident. SEWER SYSTEM MANAGEMENT PLAN Sanitary Sewer Overflow Emergency Response Plan 51  Review SSO volume estimate, volume recovered estimate, volume estimation assumptions and associated drawings.  Review past maintenance records of affected manholes and pipe segments.  Review past CCTV records.  Conduct new CCTV inspection, if necessary.  If the SSO is located within the designated hot spot areas, consider increasing the maintenance frequency.  Review any FOG related information or results from RWQCP  If the SSO is due to pipe failure, schedule repair or replacement as soon as feasible.  If the SSO is due to an under-sized pipe, infiltration/inflow or other engineering defect, contact the Utilities Engineering Division for inclusion in the CIP work.  Develop agreed upon changes and additions to the OERP and/or City Procedures resulting from the investigation and debrief session(s). 6.11 Training Applicable WGW staff shall receive annual refresher training on the procedures in the OERP. Collection system sewer maintenance and construction contractors are required to participate in training on the City OERP or demonstrate and document to the City’s satisfaction that they have been trained on emergency response procedures equivalent to those in the City OERP. City staff training will be conducted both in the classroom and in the field. Training attendance will be documented and certified by management. Exit exams will be required for certain but not all trainings. Additional training of wastewater collection system staff and contractors is discussed in Section 4.5 of this SSMP.

Fats, Oils, and Grease (FOG) Control Program SWRCB Waste Discharge Requirement: 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. Fats, oils, and grease, abbreviated as FOG, are an issue due to their ability to cause sanitary sewer blockages that may result in discharges of untreated wastewater from the City collection system. FOG discharges result from improper management of food waste in residences and commercial Food Service Establishments (FSEs). The City has over 300 FSEs in its jurisdiction. The RWQCP adopted an ordinance in 1992 requiring FSEs with grease generating activities to install grease removal devices. Additional ordinance requirements addressing FOG from FSEs were adopted in 2002, including a prohibition on installation of food waste disposers (garbage disposals), and a requirement that existing food waste disposers be removed by January 1, 2007. The Sewer Use Ordinance (SUO) was revised in 2008 and again in 2010 to include specific requirements for FSEs, to codify previously established Best Management Practices (BMPs) and to establish Grease Control Device installation requirements. 7.1 Goals for the FOG Program The City of Palo Alto implements a FOG Control Program due to the significant number of FOG-generating FSEs in the City. The benefits of a FOG Control Program include FOG discharge prevention to the sanitary sewer and storm drain systems, storm drain pollution prevention from SSO’s and FSE practices, reducing the number of FOG- SEWER SYSTEM MANAGEMENT PLAN Fats, Oils, and Grease (FOG) Control Program 63 related SSO’s, improving public health and safety, avoidance of overflow-related fines, minimizing property damage claims, reducing sewer maintenance costs and improving the FSE business environment. The primary goal of the FOG program is to reduce the number, severity and frequency of SSO’s linked to FOG and to reduce the environmental impacts and the costs associated with SSO clean up. Since 1996, the City began development a food service program to include appropriate SUO provisions, site inspection procedures, enforcement action procedures, BMPs for FSEs, outreach and education. The FOG Program began during the second half of 2006 with the addition of a full time FOG Program Investigator. In 2008, the program enhanced its data management system to track inspections, follow-up letter enforcement and storm drain program inspections as they relate to FSEs. 7.2 Outreach 7.2.1. Regional Outreach The Bay Area Pollution Prevention Group (BAPPG) promoted proper disposal of kitchen fats, oils, and grease on Bay Area Univision Spanish radio stations between Thanksgiving week and New Year’s Day in 2012. Univision aired a total of 68 paid radio spots (48 – 60 second and 20 – 30 second) on radio stations KSOL and KBRG. Additionally, Univision broadcasted 104 paid audio streaming ads on their radio website (www.univision.org) featuring a banner directing the audience to www.baywise.org. Univision also included 90 complimentary PSAs on KSOL, KBRG, and KVVF. The campaign included a total of 262 spots making 1.8 million gross impressions at a cost of $0.0045 per impression. 7.2.2. Residential Outreach Outreach for residents is an important component of the FOG program. The City maintains an interactive website http://www.cityofpaloalto.org/news/displaynews.asp?NewsID=341&TargetID=150 dedicated to Fats, Oils and Grease in the sewer system. The site educates residents how to keep FOG out of the sanitary sewer system and provides a contact number for additional information. In November 2012, residents received a utility bill insert informing residents to pour cooking oil into a container and bring it to the Household Hazardous Waste events held once a month. In addition, over 3,000 households in areas identified as having historically higher SSOs in residential areas (Old Palo Alto, Barron Park and Charleston Meadows) as well as an apartment complex associated with a SSO, received a postcard. The postcard informed residents to bring cooking oil to the household hazardous waste event and to participate in a raffle. Ten gallons of cooking oil were collected at each of the events during the holidays (December and January). Several residents brought the utility bill insert or postcard, demonstrating that this was an effective outreach tool. SEWER SYSTEM MANAGEMENT PLAN Fats, Oils, and Grease (FOG) Control Program 64 In February of 2012, the city of Palo Alto moved the waste oil drum for residents’ tallow (yellow grease or used cooking oil) from the recycling center to the RWQCP. Tallow will be collected from residents during Household Hazardous Waste events or scheduled drop-offs. Outreach efforts are further detailed in the City’s annual Clean Bay Plan report. 7.3 FOG Disposal Adequate disposal options for FOG are available in the region. The City manages the CalFOG website that includes a list of grease receiving and disposal facilities. The list can be accessed at http://www.calfog.org/GreaseFacilities.html. 7.3.1 Acceptance at RWQCP and Maximizing Energy Recovery In 2008, City staff investigated the FOG acceptance procedures at the RWQCP. The goal was to evaluate the potential to receive all hauler loads associated with the Grease Waste Hauler Contract in the City of Palo Alto and possibly other Cities in the RWQCP’s service area, which would include non-contracted haulers. At the present time, there is limited capacity for accepting more than the current amount of approximately 6,000 gallons of grease waste hauler loads per day. The RWQCP’s acceptance of GCD waste material cannot exceed 130,000 gallons per month or 1.56 million gallons per year. The RWQCP Long-Term Facilities Plan discussed the benefits of adding FOG to digesters, if digesters are chosen as a biosolids handling technology. FOG addition can significantly increase energy production. On November 8, 2011 Palo Alto voters approved Measure "E", which opened up 10 acres of Byxbee Park adjacent to the RWQCP for a ten-year period while an Energy/Compost Facility is considered for the site. The facility could, if approved, utilize FOG, food scraps, yard trimmings, and wastewater solids in the production of energy and compost. The City of Palo Alto developed a process and timeline for consideration of such a facility, as a first step following the passage of Measure "E" 7.3.2 Coordination/Data Management The Utilities Water Gas Wastewater and Public Works Watershed Protection groups now use ICOMMM to document referrals of FOG issues for investigation. When FOG is found in commercial areas, Utilities Operations sends a work order to Watershed Protection for follow up with nearby restaurants. In addition, for an apartment complex, Watershed Protection has assisted with the follow up. Outreach is also targeted using this database to prioritize areas with grease related overflows for receipt of outreach material. SEWER SYSTEM MANAGEMENT PLAN Fats, Oils, and Grease (FOG) Control Program 65 7.4 Legal Authority Chapter 16.09 of the Palo Alto Municipal Code (SUO) provides the legal authority to regulate FOG discharges to the sewer system. The SUO has specific grease control requirements for Food Service Establishments. Table 7-1 contains a summary of the SUO provisions pertinent to FOG control. Table 7-1: Sewer Use Ordinance Provisions for FOG Control Provision Palo Alto Municipal Code Reference Prohibitions 16.09.035 Standards 16.09.040 Grease Disposal Prohibited 16.09.050 Unpolluted Water 16.09.055 Standards for Other Industrial Wastes 16.09.060 Best Management Practices 16.09.065 Trucker’s Discharge Permit 16.09.070 Food Service Establishments 16.09.075 Reporting Requirements for all Permitted Dischargers 16.09.135 Requirements for Reporting Noncompliance, Increased Loading, Slug Discharges, Accidental Discharges 16.09.140 Storm Drains – Prohibited Discharges 16.09.165 Requirements for Construction Operations 16.09.170 General Prohibitions and Practices 16.09.175 Requirements for Newly Constructed, Remodeled or Converted Multi Residential, Commercial and Industrial Facilities 16.09.180 Enforcement – Notice of Non Compliance 16.09.245 Enforcement – Administrative Compliance Order 16.09.250 Enforcement: Criminal Penalties 16.09.255 Enforcement – Administrative Citation 16.09.260 Enforcement – Administrative Civil Penalties 16.09.265 Enforcement – Judicial Civil Penalties 16.09.270 Damage to Facilities 16.09.275 City Right to Terminate Discharge 16.09.280 SEWER SYSTEM MANAGEMENT PLAN Fats, Oils, and Grease (FOG) Control Program 66 7.5 Source Control The City has several high density and high volume restaurant areas including Downtown, Midtown, and the California Avenue Business District, which are known hotspots for collection system impacts related to FOG discharge. There are also several smaller clusters of FSEs and individual restaurants that warrant FOG controls. These areas and specific FSEs have been the primary targets for increased inspection, enforcement, and preventive cleaning. The partner cities to the RWQCP (City of Mountain View, City of Los Altos, East Palo Alto Sanitary District, Town of Los Altos Hills and Stanford University) remain responsible for their collection systems, SSMPs and FOG Control Programs. The City of Palo Alto will continue to support the satellite systems as needed with creation of outreach materials, training, and assistance with FSE inspections. The City’s FOG Program staff in Public Works – Environmental Services manages plan check and specifications for newly constructed and remodeled FSEs to ensure items required by the Palo Alto Municipal Code and Uniform Plumbing Code are completed prior to approval of building permits. Grease-generating drainage fixtures must be connected to a grease control device (GCD). Non-grease generating drainage fixtures including hot discharge equipment can be connected directly to the sanitary sewer system. When drainage fixtures are properly plumbed and the GCDs are properly maintained, there should be very little to no FOG discharging to the sanitary sewer system. Improperly plumbed pipes and drainage fixtures are generally associated with FOG buildup downstream, and occurrences of sewer backups or SSOs. The SUO includes a requirement for undesignated retail spaced, ensuring that new buildings must retrofit to meet the requirements if an FSE is located in new building’s undesignated retail space. New buildings constructed to house food service establishments are required to include a covered area for trash, recycling, tallow (used oil) and compostable. The area is designed to prevent water run-on to the area and runoff from the area. Drains that are installed within the enclosure for recycle and waste bins, dumpsters and tallow bins (used oil containers) serving food service facilities are optional. Any such drains installed must be connected to a GCD and the sanitary sewer. If tallow is to be stored outside, then an adequately sized, segregated space for a tallow bin must be included in the covered area. 7.6 Inspections There are over 300 FSEs in the City of Palo Alto. The FOG program includes comprehensive inspections and enforcement. Inspections of FSEs occur on a routine basis, and the City conducts more frequent inspections and enforcement where necessary based upon FSE performance. The Clean Bay Pollution Prevention Plan includes the goal of inspecting at least one-third of the FSEs each year. SEWER SYSTEM MANAGEMENT PLAN Fats, Oils, and Grease (FOG) Control Program 67 The City’s main goals for FSEs are to have GCDs maintained frequently enough to prevent FOG from escaping from GCDs and entering the sanitary sewer system, ensuring drainage fixtures are correctly plumbed, keeping a maintenance log for GCDs, not to wash kitchen equipment or discharge wastewater to the storm drain system, and to maintain the tallow bin and trash areas free of FOG and debris. The FSEs are categorized by their potential to contribute FOG to the sanitary sewer or storm drain system. Facilities located in hot spots or that have otherwise been problematic are addressed first and receive more frequent inspections. FSEs are prioritized in one of the following categories:  Problem FSEs in hot spots  Problem FSEs not in hot spots  FSEs in hot spots  FSEs that have only had minor issues in the past  FSEs with potential to generate FOG  FSEs without significant potential to generate FOG (juice bars, coffee shops, etc.) Past experience has shown that some facilities will frequently not meet all requirements and will need ongoing attention. These facilities will be re-visited as necessary. Facilities that demonstrate compliance will receive less attention. During the inspections, the FSE is ranked on a scale of 1 (worst) to 5 (best) on their compliance with BMPs and ordinance requirements. BMPs include:  Removing food waste from preparation and service items prior to washing and disposal in the trash or food scrap container (dry wipe pots, pans, and dishes before washing);  Installing drain screens in all sinks, drains, floor drains, floor sinks, dishwashers, etc. Clean screens frequently into the trash or food scrap container;  Cleaning water from floors, floor mats, exhaust hoods, large kitchen equipment, trash, recycling, tallow containers, or other dishwashing not done in a dishwasher, should be directed to the GCD prior to discharge, including outdoor cleaning;  Maintain exhaust hood and vent grease collections devices, including those on roofs, in hoods and removable filters to prevent spills and overflows;  Dispose of waste oil/grease in a tallow receptacle that is kept free of spills, and closed with a lid;  Prevent storm water pollution by keeping waste containers and surrounding area covered, clean and free of FOG and food residue, debris and leaks; and SEWER SYSTEM MANAGEMENT PLAN Fats, Oils, and Grease (FOG) Control Program 68  Cleaning up spills using dry methods first (sweeping, rags, absorbent material that are disposed in the trash), then mop and bucket. Mop water is discharged through the GCD. FSEs that cause problems in the sanitary sewer, storm drain systems or have violations of their BMPs are rated 1 or 2 depending on their location. The problematic facilities that rank 1 or 2 have one of more of the following issues:  Experienced back-ups or overflows;  Contributed to FOG build up in the sanitary sewer (identified by CCTV or cleaning records);  Unresolved compliance issues;  Failed to follow the proper BMPs;  Failed to keep records;  Had storm drain violations; and/or  Failed to comply with verbal or written directives. The City receives updated lists of FSEs from the County of Santa Clara, Department of Environmental Health and the Consumer Protection Division. Not all of the facilities on the list require an inspection by the City, as many are farmer’s markets, gas stations and general food vendors. In addition, staff attends weekly Development Review Committee meetings and is routed building plans for buildings that include FSEs. The program includes different inspection types including FSE storm drain system inspections, full FSE FOG inspections, GCD building inspections; Green Business Compliance inspections and residential inspections. Efforts are concentrated in areas of known problems and facilities with historical issues or known potential to discharge grease. Enforcement actions include Verbal Warning, Warning Letters, Notices of Non- compliance, Compliance Agreements and Administrative Citations consistent with the Enforcement Response Plan (ERP) for either wastewater or stormwater violations. During FSE inspections, outreach materials are distributed as appropriate. The BAPPG funded CalFOG to create a poster that is available in English, Spanish, Korean, Chinese, and Vietnamese. In addition to the posters, BAPPG created food scrapers with the RWQCP’s insignia and local disposal contact info from www.cleanbay.org and a phone number. These food scrapers are BMP tools to help scrape off any remaining food and FOG waste into the trash prior to rinsing kitchen items. Food scrapers are generally distributed to FSEs during inspections. In 2012, FOG Program staff created a fact sheet detailing the requirements for FSEs. This fact sheet is provided to FSEs during the permitting process to ensure that all are aware of the SUO requirements and enforcement response plan. Requirements, as well as the ban on Expanded Polystyrene (EPS) takeout containers. SEWER SYSTEM MANAGEMENT PLAN Fats, Oils, and Grease (FOG) Control Program 69 City staff educates the FSE management and staff on ordinance requirements and BMPs to the extent practical during inspections. If a violation is observed, the inspector issues enforcement consistent with the Enforcement Response Plan. For FSE’s that do not achieve compliance, enforcement will be escalated according to the appropriate Enforcement Response Plan (Pretreatment or Storm water). During the FSE storm drain system inspections compliance with storm drain regulations is assessed. Outdoors cleaning of kitchen equipment, dumping of mop water, and poor housekeeping around trash compactors, trash bins and tallow bins are addressed. Outreach materials, including those developed by the Santa Clara Valley Urban Runoff Pollution Prevention Program (SCVURPPP) are distributed to FSE’s during inspections and with follow-up Letters as appropriate. 7.7 Compliance Table 7-2 contains a historical summary of FOG FSE inspections conducted and compliance actions taken.

SEWER SYSTEM MANAGEMENT PLAN System Evaluation and Capacity Assurance Plan 70 Element 8. System Evaluation and Capacity Assurance Plan SWRCB Waste Discharge Requirement: 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 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 Sewer System Management Plan (SSMP) review and update requirements as described in Section D. 14. 8.1 Evaluation The City of Palo Alto’s Sanitary Sewer CIP plan is based on the 2004 Wastewater Master Plan, CPA’s Wastewater Operations’ identified deficiencies (repairs or replacements), and CCTV evaluation and assessment. In 2004, an update of the Master Plan was completed by MWH Americas titled, “Wastewater Collection System Master Plan –Capacity Assessment”, March 2004 (Master Plan) and approved by the City Council. The Master Plan evaluated the effectiveness of the previous 1988 Master Plan Study completed by CDM. It included a model of the collection system and an evaluation of the ability for the system to convey existing and future peak flows from a 5-year design storm, along with identification of areas with limited capacity and the need for system improvements and rehabilitation. Collection system improvements were designed for a 20-year design storm. The City requires all new developments, on a case by case basis, that propose to connect to the City system, to provide capacity evaluations to determine that the existing system can transmit the proposed flows from the new development without SEWER SYSTEM MANAGEMENT PLAN System Evaluation and Capacity Assurance Plan 71 exceeding the City’s design criteria from the Master Plans. If deficiencies are found, the evaluation must provide solutions to allow the addition of these expanded flows to the collection system without causing SSOs or system failures. This also includes capacity expansion evaluations for satellite agencies Stanford University and Los Altos Hills that currently discharge directly to and utilize capacity in the Palo Alto collection system. 8.2 Design Criteria The 1988 Master Plan Study was effective in identifying the capacity deficiencies and recommended appropriate CIP projects. Between 1990 and 2004, a majority of these CIP Capacity projects were designed and constructed. The 2004 Master Plan study further refined the previous study with more accurate modeling and significantly reduced the number of remaining capacity projects, which allowed us to refocus our attention on I/I CIP projects. Since 2004, the remaining CIP projects identified in the 2004 Master Plan, which addressed current capacity deficiencies, have been completed. See Section 5.1 for WW Design Standards governing design and construction methods. 8.3 Capacity Enhancement Measures Projects in the 2004 Master Plan were broken into three groups, phases ‘A’, ‘B’, or ‘C’. The ‘A’ group consists of high priority projects. The ‘B’ group corrects relatively minor deficiencies. The ‘C’ group identifies potential future deficiencies. The groups relate to surcharge levels of the hydraulic grade line determined by the collection system model. The Master Plan identified eight locations where capacity-related improvements were required, generally in small diameter pipelines. These eight improvement projects have since been completed and the collection system no longer has any known capacity deficiencies. From 2005 through 2007 a CCTV project was completed to assess the condition of the sanitary sewer collection mains. Pipe deficiencies identified on the video, were coded using Palo Alto’s CCTV rating system. The relative values assigned to each code provided a condition assessment of the collection system. ICOMMM, asset management software, adds up the values in a pipe segment and divides by the total length to determine a Damage Severity Index (DSI) of each pipe segment. The DSI generated by ICOMMM helped assess relative pipe condition and quickly verify the assessment by graphically displaying the results within ICOMMM. Graphical displays assist us in grouping areas into one project. Rehabilitation projects are based upon the relative DSI scores supplemented by the results of the 2005 to 2007 CCTV condition assessment results and field crew observations and input. This work has resulted in the CIP budgeting of three to four million dollars per year to systematically rehabilitate the City sanitary sewer collection system, including pipelines and manholes. The annual projects include between 20,000 and 30,000 linear feet of SEWER SYSTEM MANAGEMENT PLAN System Evaluation and Capacity Assurance Plan 72 pipe (depending on size) and manhole rehabilitation. In addition, it includes lower lateral replacements and necessary equipment to support the rehabilitation. The Wastewater Enterprise Fund, which is predominately funded by collection system sewer service charges, is the source of revenue for the annual CIP sewer rehabilitation projects. The funding is distributed among three Divisions: Utilities Engineering, Customer Services and Utilities Maintenance. Table 8-1 shows this distribution. Table 8-1: Sources of Annual Funding for Sanitary Sewer Rehabilitation Funding Source Responsible City Division General Equipment and Tools Utilities Engineering Sewer System Extensions – new laterals and pipelines Customer Services Division Sewer Lateral/Manhole Rehab/Replacement Utilities Maintenance Wastewater System Improvements Utilities Maintenance; Utilities Engineering Annual WW Collection System Rehabilitation Utilities Engineering Annual O&M Utilities Maintenance Contractual Line Item Utilities Maintenance The current anticipated Capital Improvement Program budgets are provided for each of the above programs in Table 4-2, Five Year Capital Improvement Program. 8.4 Schedule The annual projects include between 25,000 and 30,000 linear feet of pipe and associated manholes and attached lower laterals. The current capacity deficiencies identified in the 2004 Master Plan Study have all been constructed. An on-going 5-year CIP plan addresses I/I and other maintenance issues typically replacing lines in place. Figure 8-1 from the City’s five-year Capital Improvement Program identifies approximately 75% of the line segments that are to be rehabilitated in the next five years. The remaining 25% are line segments that are identified during the design phase. All projects are currently being or will be designed and implemented by the Utilities Engineering Division on an annual CIP Project Plan basis as detailed in Figure 8-1. All line segments represent sewer mains in the street blocks shown. Typically, the CIP projects are started in the construction year shown on the map. The project usually takes a year after the start date to complete. The City has rehabilitated approximately 33% of the 208 miles of sanitary sewer system to date and expects to add an additional 25 to 28 miles of rehabilitation in the next five years. Figure 8-2 identifies those lines that have been rehabilitated or replaced from 1986 through 2010.

Monitoring, Measurement and Program Modifications SWRCB Waste Discharge Requirement: The Enrollee shall: a. Maintain relevant information that can be used to establish and prioritize appropriate Sewer System Management Plan (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. 9.1. Maintenance of Relevant Data The City of Palo Alto Utilities staff track relevant information that is used to establish and prioritize appropriate SSMP activities. Field data such as pipe cleaning and inspection frequencies, SSOs, and lateral replacements are tracked in ICOMMM and/or other systems (for example GIS). On a monthly basis, the Business Analyst and the Operations Manager and Utilities Supervisor generate monthly reports to monitor and evaluate the effectiveness of the City’s collection system operation. The monthly report is also discussed with engineering staff at the Division’s regular monthly meetings. 9.2. Monitoring and Assessment The City has selected certain performance indicators to assess the effectiveness of the SSMP and the Utilities Operations Division of the sanitary sewer collection system. These indicators were selected because they are straightforward, quantitative, and focused on results. Changes in the indicators over time can be used to assess the overall success of the SSMP or, conversely, to identify underlying conditions that inhibit success and necessary program revisions and changes to fully implement the SSMP. The two categories of performance indicators are listed below: Data Regarding Implementation of SSMP Measures  Feet of sewer main inspected with CCTV/year  Feet of sewer main cleaned/year  Number of lower laterals with PM activity/year  Feet of sewer main treated for root control  Feet of sewer main rehabilitated  Number of lower laterals rehabilitated  Number of FSE inspections  Average response time for SSO event (Time between City becoming aware of potential SSO and First Responder arriving on site) SEWER SYSTEM MANAGEMENT PLAN MONITORING, MEASUREMENT AND PROGRAM MODIFICATIONS 76 Data Regarding Success of Preventative Maintenance  SSO Rate (SSOs/100 miles/year);  Number of SSOs for each cause (roots, grease, debris, pipe failure, capacity, lift station failures, and other);  Median SSO volume (gallons);  Percentage of SSOs greater than 100 gallons; and  Percentage of total spilled sewage reaching surface water. 9.3. Performance Data Table 9-1 contains the specific annual performance goals associated with the collection system work. The City’s Business Analyst produces monthly and annual performance reports, which will provide the data to compare to the SSMP and individual Element stated goals. The reports also present SSO performance results as certified in the State CIWQS system. This information allows the City to optimize operations in a manner that yields favorable SSO performance. Table 9-1: Palo Alto Annual Performance Goals Performance Indicator Goal Feet of sewer main inspected with CCTV/year 52,800 (10 miles) Feet of sewer main cleaned/year 385,440 (73 miles) Number of lower laterals with PM activity/year 3,000 Feet of sewer main treated for root control 5,280 (1 mile) Feet of sewer main rehabilitated 21,120 (4 miles) Number of lower laterals rehabilitated 100 Number of FSE inspections 200 Average response time for SSO event 1 hour Table 9-2: SSO Performance Indicators Performance Indicator Measured Units SSO Rate, SSOs/100 miles/year Total Annual SSOs, Number Primary Cause, Number (percent of total) Roots Grease Debris Pipe Failure Lift Station Failure SEWER SYSTEM MANAGEMENT PLAN MONITORING, MEASUREMENT AND PROGRAM MODIFICATIONS 77 Performance Indicator Measured Units Other Median SSO Volume, Gallons spilled Median SSO Volume recovered Gallons Percent of SSOs < 100 gallons Percentage Volume of Spilled Sewage Entering Surface Water Gallons Data Source: CIWQS 9.4. Performance Monitoring and Program Modifications The City will evaluate the performance of its SSMP on a biennial basis using the performance indicators noted in Section 9.2. Any operational changes that are made to improve specific performance indicators will be documented in the SSMP Audit and reflected in the revised language of the SSMP. Element 10 discusses the SSMP Audit process in detail. 9.5 Sanitary Sewer Overflow Trends The charts below summarize SSO trends during calendar years 2008 through 2012.

Program Audits SWRCB Waste Discharge Requirement: As part of the Sewer System Management Plan (SSMP), the Enrollee shall conduct periodic internal audits, appropriate to the size of the system and the number of SSOs. At a minimum, these audits must occur every two years and a report must be prepared and kept on file. This audit shall focus on evaluating the effectiveness of the SSMP and the Enrollee’s compliance with the SSMP requirements identified in this subsection (D.13), including identification of any deficiencies in the SSMP and steps to correct them. The City will audit and update its SSMP at least every two years as required by the WDR unless results of SSO Failure Analysis recommends changes and, modifications or regulations change between audits. The audit process is documented in the Annual SSMP Audit Form, shown in Appendix A. The audit form provides structure for a systematic review of each SSMP element in order to ensure the SSMP contains current information, regulatory requirements are satisfied, and programs are effective and meeting the City goals for the operation of the collection system stated in Element 1. If updates or changes are required, the content and timeline to complete those change are described in the audit form. As part of the audit process, City staff will update critical information in the SSMP, such as radio call signs, contact information, names of the required Designated Officials and the SSO response chain of communication, as needed. A comprehensive SSMP update will occur every 5 years, as required by the SSS WDR. The SSMP Audit results will be included in Appendix 10-1 effective 2014. Changes made to the SSMP will be documented in the Change Log located in Appendix B. The Change Log is effective as of September 9, 2013. SEWER SYSTEM MANAGEMENT PLAN ELEMENT 11 – COMMUNICATION PROGRAM 81 Element 11. Communication Program SWRCB Waste Discharge Requirement: The Enrollee shall communicate on a regular basis with the public on the development, implementation, and performance of its Sewer System Management Plan (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. Outreach and public education are an important part of the City of Palo Alto’s operations. On an annual basis, the City utilizes various media (newspaper, utility insert and website) to inform utility customers of various topics including sanitary sewer collection system issues. Most recently, public outreach material on “how to keep your sanitary sewer working properly” was published on the web and sent to customers. The outreach material provided instructions for reporting sewer blockages and overflows to the City’s dispatch center. In addition, the Environmental Compliance Division (ECD) distributes public education materials on proper disposal and handling of the household grease. A copy of the City of Palo Alto SSMP is available in the City library and will be available on the City’s web site once the revised SSMP is approved by the City Council. A section of the website entitled “Sewer System Management Plan” is in place. The website will include a link to the SSMP, as well as a link to the California Integrated Water Quality System’s (CIWQS) public reports. This website provides public access to reported SSO data and information about regulatory developments and performance of the SSMP and collection system operations. A communication plan with the collection systems tributary to the RWQCP (Partner agencies) is already in place and meetings are held and documented periodically on various topics of mutual interest. Copies of meeting agendas and summaries can be obtained at the Utilities Maintenance Division offices.

The City of Palo Alto (“the City”) owns and operates a sanitary sewer collection system serving a population of approximately 66,000 customers in a 26 mile service area. The City’s sanitary sewer collection system consists of pipelines, mains, manholes and one lift station for the purpose of collecting and transporting sewerage from properties within the City of Palo Alto service area and connected to the City collection system to the Palo Alto Regional Wastewater Treatment Plant for proper treatment and disposal. B. In May 2006 the State Water Resources Control Board (the “State Board”) adopted Statewide Sanitary Sewer System Waste Discharge Regulations (“WDRs”) including Monitoring and Reporting Programs (“MRPs”) for all sanitary sewer collection systems greater than one mile in length and discharging to a publicly owned sewage treatment facility. C. The State Board’s WDRs require that an enrolled sanitary sewer collection system prepare and implement a Sanitary Sewer Management Plan (SSMP) that provides for adequate resources for the proper management, operations, maintenance and capacity assurance of the collection system to reduce or eliminate sanitary sewer overflows. D. The State Board WDRs further require that each enrolled collection system report all sanitary sewer overflows to the State reporting system and that all reports be certified by Legally Responsible Officials under penalty of perjury. E. The City Council of the City of Palo Alto adopted the City’s SSMP in July 2009. F. The State Water Resources Control Board Executive Officer on July 26, 2013 issued Order No. WQ 2013-0058-EXEC amending the Monitoring and Reporting Program for Statewide General Waste Discharge Requirements for Sanitary Sewer Systems effective September 9, 2013, which are applicable to all sanitary sewer collection systems enrolled under the Waste Discharge Regulations, including the City of Palo Alto. G. The City has revised its SSMP to meet the requirements of the amended MRP. H. The revised SSMP was presented to the City Council at a regularly scheduled Council Meeting on November 4, 2013 allowing for public input prior to consideration and adoption. I. The WDRs require the City to maintain continuous coverage by a Legally Responsible Official (LRO) registered with the State Water Board, for purposes of managing and certifying the activities of the City’s sanitary sewer collection system. NOT YET APPROVED 131024 sh 6051991 J. Currently the City has a single employee classification designated as its Legally Responsible Official, and desires to expand the designation of employee LRO classifications to assure full coverage of collection system activities. NOW, THEREFORE, the Council of the City of Palo Alto does RESOLVE as follows: SECTION 1. The City Council of the City of Palo Alto approves and adopts the revised City of Palo Alto Sanitary Sewer Management Plan, dated October 2013. SECTION 2. The Council designates the following City employee classifications as Legally Responsible Officials for purposes of the State Water Resources Control Board Sanitary Sewer System Waste Discharge Regulations: Assistant Director of Utilities Operations Water Gas Wastewater Operations Manager Utilities Compliance Manager Wastewater Collections Supervisor SECTION 3. The Council finds that the adoption of this resolution does not meet the definition of a project under the California Environmental Quality Act (CEQA) pursuant to California Public Resources Code Section 21065, thus no environmental assessment is required.
