Town of Los Altos Hills Sewer System Management Plan iv • INTRODUCTION. This introductory section provides background information on the purpose and organization of the Sewer System Management Plan (SSMP), as well as a brief overflow of the Town's service area and sewer system. SWAP Requirement Background This SSMP has been prepared in compliance with requirements of the San Francisco Bay Regional Water,Quality Control Board (RWQCB) pursuant to Section 13267 of the California Water Code, as described in the letter from the RWQCB to the Town of Los Altos Hills (Town) dated July 7, 2005. The RWQCB letter mandates that the Town prepare an SSMP following the guidelines in the SSMP Development Guide prepared by the RWQCB in cooperation with the Bay Area Clean Water Agencies(BACWA).The Town must also comply with RWQCB sanitary sewer overflow(SSO) electronic reporting requirements issued in February 2008. More recently, the State Water Resources Control Board (SWRCB) acted at its meeting on May 2, 2006 to require all public wastewater collection system agencies in California with greater than one mile of sewers to be regulated under General Waste Discharge Requirements (GWDR). The SWRCB action also mandates the development of an SSMP and the reporting of SSOs using an electronic reporting system. The SWRCB SSMP requirements are similar to the RWQCB requirements,but differ in orgsni7ation and some details. Document Organization This SSMP is intended to meet the requirements of both the RWQCB and the Statewide GWDR. The organi7ation of this document is consistent with the RWQCB guidelines, but the contents address both the RWQCB and SWRCB requirements. The SSMP includes eleven elements, as listed below. Each of these elements forms a section of this document. Parentheses indicate the title of the comparable SWRCB element. 1. Goals 2. Organi7ation 3. Overflow Emergency Response Plan 4. Fats,Oils and Grease Control Program 5. Legal Authority 6. Measures and Activities(Operation and Maintenance Program) 7. Design and Construction Standards(Design and Performance Provisions) 8.

Identification of associated appendix and list of supporting information included in the appendix. 3. Discussion of element. The discussion may be split into multiple sub-sections depending .on length and complexity. Supporting information for each element is included in an appendix associated with that section, as applicable. In general, information expected to require relatively frequent updates (such as names and phone numbers of staff) are included in appendices, as well as other supporting "- - information,such as forms or schedules. Town Service Area and Sewer System The Town of Los Altos Hills (Town) covers an 8.4 square mile area in .SantaClara County adjacent to the City of Los Altos and the City of Palo Alto. The Town is primarily residential, with a population of approximately 8,000 and a minimum parcel size of one acre.Approximately half of the Town's propertiesareserved by the sanitary sewer system; the remainder parcels are on septic tanks. An,additional 5.8 square miles of unincorporated land adjacent to the Town's. boundaries have been designated by the County of Santa Clara as being within.the Town's Sphere of Influence, and may be subject to the Town's guidelines for annexation. The Town's sewer system consists of approximately 58 miles of pipe.Pipe diameters range from 6 to 8 inches,with the majority(approximately 90%by length) 6 inches in diameter. The system includes two lift stations owned and maintained by the Town(Purissima.and O'Keefe),as well as several privately-owned and maintain lift stations.Collected_sewage is conveyed via the City of Palo Alto or the City of Los Altos sewer systems to the Palo Alto Regional Water Quality Control Plant for treatment. There are two sewer basins in Town where the southern portion of the system drains to the City of Los Altos, and the northern portion of the system drains to the City of Palo Alto. Both basins are maintained by a private contractor,Veolia Water West Operating'Services, Inc. (Veolia Water).. Veolia Water assists the Town in sewer operations,maintenance, and emergency response. The Town is responsible for the mainlines in sewer collection system while private homeowners are responsible for their own lateral.between the building and the mainline connection. Additionally,the 12-inch trunk sewers within the Palo Alto Basin are owned and maintained by the City of Palo Alto. Town of Los Altos Hills Sewer System Management Plan - ' . 2 • Element 1: GOALS This SSMP element identifies goals the Town has set for the management, operation and maintenance of the sewer system and discusses the role of the SSMP in supporting these goals. These goals provide focus for Town staff to implement improvements in the management of the Town's wastewater collection system. This section fulfills the Goals requirement of both the RWQCB(Element I)and the SWRCB (Element 1)SSMP requirements. 1.1 Regulatory Requirements for Goals Element The summarized requirements for the Goals element of the SSMP are as follows: RINQCB Requirement: The collection system agency must develop goals to manage, operate, and maintain all parts of its collection system. The goals should address the provision of adequate capacity to convey peak wastewater flows, as well as a reduction in the frequency of sanitary sewer overflows (SSOs)and the mitigation of their impacts. SWRCB Requirement: ` The collection system agency must develop goals to properly manage, operate, and maintain all parts of its wastewater collection system in order to.reduce and prevent SSOs, as well as to mitigate any SSOs that occur. 1.2 Element 1 Appendix There is no appendix associated with Element 1. 1.3 Goals Discussion This SSMP contributes to the proper management of the collection system and assists the Town in minimizing the frequency and impacts of SSOs through appropriate maintenance and emergency response. Specific goals of the Town's SSMP are as follows: 1. To minimize the frequency of SSOs. 2. To mitigate impacts associated with S SOs. 3. To effectively coordinate with contractors to provide efficient and effective SSO response. 4. To effectively coordinate with contractors to properly manage, operate, maintain all portions of the Town's wastewater collection system. 5. To provide adequate capacity to convey peak wastewater flows within the Town service ( area. \ i 6. To plan for the appropriate renewal and replacement of wastewater collection system facilities to maintain their long-term structural integrity and reliability. 7. To meet all applicable regulatory notification and reporting requirements. Town of Los Altos Hills Sewer System Management Plan 1-1 • • • - - Element 2: ..

The Town's Associate Engineer is .authorized to submit SSO reports to the appropriate government agencies. Responsibility for SSMP Implementation The Town's Public Works Director is responsible for the overall implementation and update of this SSMP.The Public Works Director is supported by the Associate Engineer. 2.4 SSO Reporting Chain of Communication Figure 2-2 contains a flowchart depicting the overall chain of communication for responding to and reporting SSOs, from observation of an SSO to reporting the SSO to the RWQCB. Table 2 in Appendix A contains contact numbers for all entities included in the chains of communication. ( ) The SSO Reporting process is described in more detail in Element 3: Overflow Emergency Response Plan. • Narrative Description of SSO Response.Chain of Communication A public observer of an SSO would typically call the Town Hall. During regular business hours, the Town Hall receptionist forwards the call to the Town Associate Engineer. The Associate Engineer determines the location of the SSO and then calls the appropriate agency or contractor for response, cleanup, and containment. If the SSO occurred on a main owned by the City of Palo Alto, Palo Alto responds and reports the overflow. Otherwise, after containment and cleanup,the contractor reports back to the Town Associate Engineer, and the Associate Engineer notifies the Public Works Director and appropriate regulatory agencies. After hours, the Town Hall message directs callers to County Communications. County Communications attempts to determine the appropriate agency or contractor to call for response. If they are unsure, they generally contact Public Works Director and/or Maintenance Superintendent who informs them of the correct responder to.call. Town SSOs are typically small volume(less than 1,000 gallons, with most less than 100 gallons) with little potential for human health impacts or impact to waters of the State. If a serious spill were to occur after hours, County Communications would contact the Town's Public Works . ; Director-and/or Maintenance Superintendent,who serves as the after-hours on-call personnel for all major emergencies. The Public Works Director and/or Maintenance Superintendent would then contact the appropriate response agencies as well as the Associate Engineer, who would submit the 24-hour report to the RWQCB.

This section fulfills the Overflow Emergency Response Plan requirement of both the RWQCB (Element 3) and the SWRCB (Element 6)SSMP requirements. 3.1- Regulatory'Requirements for Overflow Emergency Response Plan Element The summarized requirements for the Overflow Emergency Response Plan element of the SSMP are as follows: RWQCB Requirement: The collection system agency must develop an overflow emergency response plan (OERP) that provides procedures for SSO notification, response, reporting, and impact mitigation. The response plan should be developed as a stand-alone document and summarized in the SSMP. SWRCB Requirement: The collection system agency shall develop and implement an overflow emergency response ç . plan that identifies measures to protect public health and the environment.-At a minimum, this plan must include the following: (a) ' Proper notification procedures so that the primary,responders and regulatory agencies are informed of all SSOs in a timely manner; (b) A program to ensure appropriate response to all overflows; (c) Procedures to ensure prompt notification to appropriate regulatory agencies and other potentially affected entities (e.g. health agencies, regional water boards, water suppliers, etc...) of all SSOs that potentially affect public health or reach the waters of the State in accordance with the MRP. All SSOs shall be reported in accordance with this MRP, the California Water Code, other State Law, and other applicable Regional Water Board WDR or NPDES permit requirements. The SSMP should identify the officials who will receive •immediate notification; (d) Procedures to ensure that appropriate staff and contractor personnel are aware of and follow the Emergency Response Plan and are appropriately trained; (e) Procedures to address emergency Operations, such as traffic and crowd control and other necessary response activities; and (f) A program to ensure that all reasonablesteps are taken to contain untreated wastewater and prevent discharge of untreated wastewater to waters of the United States and minimi7e 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.

Standard Operating Procedures for Sewer Pump Station Failure(O'Keefe Pump Station) 4. VEOLIA WATER Standard Operating,Guidelines for Sanitary Sewer Overflow ' Response - 3:3 --Emergency Overflow Response Pian Discussion This section provides a brief discussion of the Town's overflow emergency response plan,which is included in full in Appendix B. The Town is unique in that it contracts out all of its sewer system maintenance and overflow.emergency response activities to its maintenance contractors: ■ VEOLIA WATER provides emergency response in the both Los Alto and Palo Alto Basins of the Town's sewer system. C) The contractor firm has theirown operational guidelines and/or emergency response plan for (`J I responding to SSOs, which are also included in Appendix B. The Town's plan was developed not to replace those documents, but rather to provide a reference for the overall emergency response process specific to the Town. Overflow Response Responsibilities The Town is responsible for responding to (via their contractors) and reporting all SSOs that are caused by problems in public sewers within their service area, with the exception of the following locations: ■ The Page Mill Road sewer main. Although located partially within Town'limits, this main is owned and maintained by the City of Palo Alto. Palo Alto is responsible for responding to and reporting sewer overflow emergencies-on this main. ■ The sewer main serving Foothill College. Although this main is located within the Town service area, it is owned and maintained by the City of Los Alto's. This arrangement is based on the agreement the Town has with the City executed in January,2007,as Foothill College pays Los Altos directly for sewer service. Los Altos is responsible for responding to and reporting sewer overflow emergencies on this main. The Town is also responsible for responding to and reporting emergencies associated with two' pump stations within their service area: Purissima Pump Station in the Palo Alto Basin and O'Keefe Pump Station in-the Los Altos Basin. The service area also contains several private pump stations,but the Town has no responsibility for emergency response or reporting for these private stations.

Although the Town does not have a formal FOG Control program, there are certain informal measures available to the Town for FOG Control. This section discusses these measures and also provides - justification why a formal FOG control program is unnecessary. This section fulfills the FOG Control requirement for both the RWQCB (Element 4) and the SWRCB (Element 7) SSMP requirements. 4.1 Regulatory Requirements for FOG Control Element The requirements for the FOG Control element of the SSMP are summarized below: RWQCB Requirement: The City must evaluate its service area to determine whether a Fats, Oils, and Grease (FOG) control program is needed. If so, a FOG control program shall be developed as part of the SSMP. If the City determines that a FOG program is unnecessary,proper justification must be provided. SWRCB Requirement: The City shall evaluate its service area to determine whether a FOG control program is needed. If the City determines that a FOG program is not needed, the City must provide justification for why it is not needed. If FOG is found to be a problem, the City must prepare and implement a FOG source control program to reduce the amount of these substances discharged to the sanitary sewer system.The FOG source control program shall include the following as appropriate: (a) An implementation plan and schedule for a public education outreach program that promotes proper disposal of FOG; (b) A plan and schedule for the disposal of FOG generated within the sanitary sewer system service area. This may include a list of acceptable disposal facilities and/or additional facilities needed to adequately dispose of FOG generated within a sanitary sewer system service area; (c) The legal authority to prohibit discharges to the system and identify measures to prevent SSOs and blockages caused by FOG; (d) Requirements to install grease removal devices (such as traps or interceptors) design standards for the grease removal devices, maintenance requirements, BMP requirements, record keeping and reporting requirements; (e) Authority to inspect grease producing facilities, enforcement authorities, and whether the City has sufficient staff to inspect and enforce the FOG ordinance; (f) An identification of sewer system sections subject to FOG blockages and establish a cleaning maintenance schedule for each section; and (g) Development and implementation of source control measures, for all sources of FOG discharged to the sewer system, for each sewer system section identified in(f) above. i Town of Los Altos Hills Sewer System Management Plan 41 Element 4: FOG Control 4.2 Element-4 Appendix Supporting information for Element 4 is included in Appendix C. This appendix includes the following documents: 1. Current list of food service facilities in Los Altos Hills 2. Residential FOG public outreach poster. 4.3 Justification for No FOG Control Program The Town has determined that a formal FOG Control program is not needed for the.following reasons: • • The Town is:nearly 100% residential. Typically, food service facilities would YP Y create the most FOG-related problems. According to the Santa Clara County Department of Environmental Health, the Town has only four food service facilities within the Town Limit. Two of these facilities, within Foothill College premise, discharge to the Foothill sewer main, for which the City of Los Altos takes responsibility. Appendix C contains a current list of food service facilities within Town limit. • Most service calls and SSOs in the Town are not driven by FOG. 4.4 FOG Control Activities Although the Town does not need a formal FOG Control Program, certain activities and measures are available for preventing or addressing FOG-related problems. Trouble Spot Identification and Cleaning The Town's contractor maintaining both the Los Altos Basin and the Palo Alto Basin conduct regular trouble spot cleaning., Although no trouble spots specifically related to grease are currently on their cleaning lists, if a grease-related problem were to occur, the area would be added to their list for preventive cleaning. Refer to Element 6: Measures and Activities for more information on the Town's preventive maintenance activities. Public Outreach Through their partnership fees to the Palo Alto Regional Water Quality Control Plant, the Town supports public outreach campaigns developed by the Plant. The Plant has developed a FOG public outreach poster targeted to residential dischargers in all of the communities that discharge to the plant,including the Town of Los Altos Hills. In addition to discouraging discharge of FOG to the sewers, this public outreach poster directs residents how to properly dispose of FOG and specifies the Plant as a disposal location for large amounts of FOG. A copy of this public Town of Los Altos Hills Sewer System Management Plan 4-2 • • Element 4: FOG Control. outreach poster is available on the internet at http://cleanbay.oreresidents/inside-your-home#467 and is also included in Appendix C. The Plant also conducts seasonal outreach to the public prior to and during the November and December holiday season. There is anecdotal evidence of increased use of cooking oil during these holidays, particularly through the use of turkey fryers. The Plant, along with supporting materials from the Bay Area Pollution Prevention Group (BAPPG), is preparing for point-of- purchase labels that indicate the proper disposal of the grease to be at deep fat fryer sales sites in local hardware stores. Legal Authority The Town's municipal code contains sections prohibiting grease discharges and requirements for grease removal devices. a. Legal authority to prohibit discharges. Section 6-4.424 of the Town's municipal code prohibits grease disposal, as follows: No person shall dispose of any grease, or cause any grease to be disposed,by discharge into any drainage piping, by discharge into any public or private sanitary sewer, by discharge into any storm drainage system,or by discharge to any land,street,public way, river,stream,or other waterway. b. Requirement of grease removal device. Section 6-4.425 of the Town's municipal code requires a grease removal device for every commercial or industrial generator of grease, as of 1997. This article also requires the business to clean out the grease removal device at least every six months and to keep a log of all grease removal cleaning. The log must be available for inspection for a 3-year period. The text of this section is included below: A. The owner of every newly constructed, remodeled, or converted commercial or industrial facility with one or more grease generating activities, including food service facilities with new or replacement kitchens, for which a building permit is issued on or after January 1, 1992, shall install or cause to be installed a grease interceptor for each grease generating activity, of a size equal to or greater than the minimum size meeting the definition of grease interceptors, as set forth in section 108 of the then currently adopted edition of the Uniform Plumbing Code. B. The owner of every commercial or industrial generator of grease, including food service facilities,serviced by a sewer collection line found to have a grease blockage, a history of grease blockage or accelerated line maintenance resulting from grease disposal shall install or cause to be installed,upon notification by the City Engineer, a grease removal device. C. The owner of every commercial or industrial generator of grease, including food service facilities, for which installation of grease removal devices is not required pursuant to subsections(a) or(b) of this section,shall install or cause to be installed a grease removal device for each grease generating activity,on or before January 1, 1997. D. All grease removal device(s)shall be installed on the premises where grease is used or generated and shall be sized in conformance with the Uniform Plumbing Code. Town of Los Altos Hills Sewer System Management Plan 4-3 • • Element 4:.

However, the Town does have additional legalagreements with the City of Palo Alto and the City of Los Altos to allow discharge of Town flow into the City systems. These agreements,are noted here for reference: • City of Palo Alto Agreement (1968). This agreement gives the Town the.right to connect to the City of Palo Alto system at certain points in order to discharge flow from specified areas. This agreement has been amended several times to add additional parcels to the allowed area. This agreement restricts discharge from Town based on average dry weather flow and peak wet weather flow. ■ City of Los Altos Agreement (1985). This agreement gives the Town the right to discharge flow to City of Los Altos sewer lines. Discharge rights are based on the number of residential units connected. This agreement also defines ownership of certain lines that are located within the Town but owned by the City (such as the line serving Foothill College). This agreement also covers maintenance and emergency response services provided by the City for Town sewers but is subsequently amended by the revised agreement entered in 2007. A revised agreement between the Town and the City of Los Altos was entered in 2007 to transfer maintenance responsibility for any liability associated with the additional capacity rights acquired in the Town. In addition, further define ownership of certain mainlines responsibilities and additional improvements required for sewer conveyance J through City of Los Altos sewer system.

Supporting information for Element 6 is included in Appendix E This appendix includes the following documents: 1. List of sewer as-built drawings 2. Veolia Water contract and scope of work 3. Hotspot cleaning list ' 4. BACWA flyer for plumber and building contractor outreach C-" 6.3 Collection System Map Discussion The Town has a CAD map of their sewer system. This map includes the following information: • Pipeline and manhole locations • Manhole numbers • Pipeline flow direction • Pump station locations,including private pumpstations • Streets and street names • Parcels andP arcel IDs Pipeline and manhole locations are accurate to the street, but are not detailed to the location within the street. Manhole numbers differentiate manholes in a particular street were assigned a unique manhole ID for each manhole.The map also differentiates parcels connected to the public sewers em versus parcels on septic systems, as well as parcels with two connections to the y� sewer system. The map is updated periodically, every few months, as errors are noted in the field. If an error is detected, the Town Associate Engineer is notified. The Associate Engineer then instructs the Engineering Technician to update the map. The Town's consultant developed GIS files of the sewer pipes and manholes as a part of the Town's most recent Sanitary Sewer Master Plan, completed in early 2004. These GIS files are reported to contain data such as a unique manhole ID,rim elevation, and invert elevation for the manholes file, and upstream manhole, downstream manhole, length, and diameter for the pipes Town of Los Altos Hills Sewer System Management Plan 6-3 • • _ . :.. ._: . Element 6: Measures &Activities file. With limited staff resources and budget, those GIS files were not kept up-to-date until last year the Town contracted with Veolia Water to provide a GIS-based Management Program. The program has been deployed at an offsite location and will be installed this year in Town's computers so Town staff can access data and generate report to strategize necessary improvements. The Town also has as-built drawings of the sewer system dating back to about 1961. A list of the as-built drawings available is included in Appendix E. In addition to the hard copies,the as-built plans are scanned and uploaded to the Asset Management Program for accessing from a centralized server. 6.4 Resources and Budget Discussion The Town funds sewer system services, including operations and maintenance, through a sewer enterprise fund. This fund is user-supported; it uses revenue from rate payers to fund sewer- related work. Sewer capital projects are also funded by the sewer enterprise fund, through transfer to the Town's capital projects fund. Fees for services are reviewed and updated annually. The Town prepares a formal Operating and Capital Improvement Program Budget each fiscal year. Budget for sewer CIP projects is typically between $300,000 and $400,000 annually. The City's latest Sewer Master Plan, completed in 2004, found that no CIP projects for capacity J. improvements are needed for the next 10 years. The Town has no operations and maintenance staff for sewers, and therefore contracts out all operations, maintenance, and emergency response to Veolia Water. The contract and scope of work for Veolia Water is attached in Appendix E. 6.5 Prioritized Preventive Maintenance Discussion As noted in previous sections of this SSMP, the Town contracts out all of its sewer maintenance activities. As of February 2011, a private contractor, Veolia"Water, provides the preventive maintenance, emergency maintenance, and response to service calls for the entire sewer system for the Town. Prior to February 2011,the Town had contracted with different private contractors to maintain Town's sanitary sewer system without providing managing the system. Preventive maintenance services now provided by Veolia Water include sewer cleaning and flushing, and regular pump station operation and maintenance, as described below. Sewer Cleaning and Flushing. In the initial year, Veolia Water is contracted to clean a cumulative 168,000 ft/year of sewers in the Town, including repeat cleaning of certain areas if necessary. Veolia Water spends a few days every month cleaning sewers to meet the minimum cleaning footage required by the Town. 1 The majority of sewer cleaning is done by flushing, although Veolia Water also uses power rodding. Sewer cleaning is prioritized based on prior service calls. If a service call results from a problem related to grease or roots, Veolia Water automatically adds the location to their Town of Los Altos Hills Sewer System Management Plan - 6-4 • Element 6: Measures &Activities preventive maintenance hotspot cleaning list. Most problems are related to roots. The hotspot cleaning list for the Town sewer collection system is included in. Appendix E. Since Veolia Water started providing maintenance service for the Town, a cumulative hotspot list is maintained to incorporate into routine cleaning with a various frequency. Veolia Water provides the Town a record of preventive maintenance performed on each sewer line segment. Thisrecord includes the date the maintenance was performed, street name, manhole numbers; footage of pipe, method of cleaning, and notes on findings (grease, roots, etc.). Veolia Water also submits monthly reports of the total length of sewers cleaned and schedule for upcoming cleaning areas. Pump Station Preventive Maintenance. The Town owns two pump stations, Purissima and O'Keefe. Purissima pump station was designed for low flow, high head, and therefore has two submersible pumps that pump to two dry pit pumps. O'Keefe pump station has two submersible pumps. Since February 2011, Veolia Water has been providing preventive maintenance for both of the Town's pump stations (Purissima and O'Keefe). Preventive maintenance includes the following activities: ■ Weekly o Visually inspect and check the wet well levels to ensure proper automatic start/stop levels for the pumps. o Check pumps for unusual noise or vibrations o Inspect dry pit pumps and motors for leaks,unusual noise or vibrations o Record hour meter readings for each pump bank o Clean and maintain the pump station area o Inspect the motor control center for proper operations ■ Every 2 Months o Conduct amperage test on each pump bank o Perform meg test on each pump motor to detect moisture in windings • Every Year o Perform yearly maintenance and inspection of the sewer pumps per current ITT Flygt recommended checklist. • As-Needed o Vacuum wet well on an as needed basis. Additionally, Veolia Water performs generator maintenance at the Purissima pump station every two weeks, as follows. O'Keefe pump station does not have an on-site generator. - ■ Exercise generator, simulate power failure to insure automatic startup • Record generator hour meter reacting ■ Check generator batteries, fuel, oil, and coolant levels Town of Los Altos Hills Sewer System Management Plan 6-5 I 411. = Element 6::Measures &Activities 6.6 Scheduled Inspections and Condition Assessment Discussion The Town inspects sewers by CCTV annually. Length of sewers inspected each year depends on available budget, but baseline CCTV averages about 9,000 feet per year. Additional CCTV above baseline is done as-needed. Between 2011 and 2012, the Town CCTV inspected approximately 13,000 if of sewer pipeline. The Town notes on a map which pipelines are inspected each year and the information is also uploaded to the GIS-based Asset Management Program System. Pipes selected to be CCTV inspected each year are based on locations with maintenance problems and areas that have not been inspected recently. As part of preparation of the Town's latest sewer master plan (completed in January 2004), CCTV inspection tapes were reviewed for condition assessment of 34,0001f of the Town sewer system. This condition review found that the majority of pipes are in satisfactory structural condition. Since then,the Town investigates only areas with repeated or known issues. The Town performs annual rehabilitation to correct problem areas identified during CCTV inspections. Pipes are typically replaced through pipe bursting or open trench construction, or spot repairs are made; the Town does not typically line pipes. Previously, the Town does not :_-)) have a formal prioritization process for ranking rehabilitation projects,but relies on its Associate Engineer to review CCTV reports each year and to identify the rehabilitation projects most needed based on engineering judgment. However, with the new Asset Management Program about to launch, the Town will be able to utilize the program to rank the pipe conditions and prioritize rehabilitation projects using standardized NASSCO. As a usual practice without the program, the Associate Engineer considers the following factors in selecting and prioritizing rehabilitation projects: ■ Recommendations of the CCTV contractor ■ Severity of defects (including offset joints, broken joints, sagging, debris, or root intrusion)based on CCTV report review • Location of project. Rehabilitation projects are considered higher priority if they are in the following locations: o Area with chronic problems with SSOs or blockages o Areas where a potential overflow could have the worst impact(e.g. next to a creek or downstream in the system where overflow volumes could be greater) o Pipes in easements,since these pipes are more difficult to maintain Between 2010 and 2011, the Town rehabilitated about 3,200 feet of pipe (about 1% of the system)using either pipe bursting or open trench method. Manhole Inspection As part of the cleaning program, Veolia Water staffs visually inspect manholes for corrosion, debris or damage around the base, cracks or holes, and condition of manhole steps, and notifies the Town Associate Engineer if there are any problems. Town of Los Altos Hills Sewer System Management Plan 6-6 Element 6:Measures &Activities n Pump Station Inspections and Assessment Pump stations are inspected regularly by Veolia Water, as discussed under section 6.5 Prioritized Preventive Maintenance Discussion. - ; 6.7 - Contingency Equipment and Replacement Inventories Since the Town serves less than 10,000 people,this section is not required by the RWQCB. Because of its small size, the Town does not keep any equipment or replacement partson hand. The Town relies on its-sewer maintenance contractor, VEOLIA WATER, to supply cleaning, maintenance, and emergency response equipment. The Town obtains replacement parts for its system and pump stations as-needed.The Towns pump stations include redundant pumps. 6.8 Training Discussion As discussed previously, the Town has no operations or maintenance staff, but uses the private contractor Veolia Water to provide all operations, maintenance, and emergency response for its collection system. Veolia Water's main staffs are CWEA certified are trained within the organization. They also • (P get retraining on an annual base for confined space entry safety and general job site safety. } Management team gets training at various workshops throughout the year and makes sure the field crew has the most up-to-date training. . 6.9 Outreach to Plumbers and Building Contractors Discussion Since the Town serves fewer than 10,000 people, the Town is not subject to this SSMP requirement.However the Town could benefit from the regional outreach coordinated by the Bay Area Clean Water Agencies (BACWA) on behalf of wastewater agencies throughout the Bay Area. BACWA has prepared a generic flyer for outreach to plumbers and contractors, which the Town can customise for its own use.This flyer is attached in Appendix E.

This section fulfills the Capacity Management SSMP requirement for the RWQCB (Element 8) and the System Evaluation and Capacity Assurance Plan SSMP requirement for the SWRCB(Element 8). 8.1 Regulatory Requirements for Capacity Management The requirements for the Capacity Management element of the SSMP are summarized below. RWQCB Requirement: Since the Town's collection system serves fewer than 1.0,000 residents, the Capacity Management element can be waived per RWQCB requirements. The requirement for agencies serving more than 10,000 residents is summarized here for reference. The RWQCB Capacity Management requirement is divided into two sections: ), (a) Capacity Assessment: The wastewater collection system agency shall establish a process 11 to assess the current and future capacity requirements for the collection system facilities. The SSMP should describe whether a current capacity assessment has been prepared, and if not,provide a schedule of activities for completing an assessment. (b) System Evaluation and Capacity Assurance Plan: The wastewater collection system agency shall prepare and implement a capital improvement plan to provide hydraulic capacity of key sewer system elements under peak flow conditions. Once the capacity assessment described in (a) above has been completed, a capital improvement program must be implemented to address any capacity needs. The SSMP should briefly describe the capital improvements anticipated and be updated as implementation occurs and priorities change. SWRCB Requirement: The wastewater collection system agency shall prepare and implement a capital improvement plan that will provide hydraulic capacity of key sewer system elements under peak flow conditions.This plan must include: (a) Evaluation: The agency must identify actions needed to evaluate those portions of the sewer system that are experiencing or contributing to an SSO discharge caused by hydraulic deficiency. The evaluation must provide estimates of peak flows, estimates of ( the capacity of key system components, hydraulic deficiencies, and the major sources that contribute to the peak flows associated with overflow events. Town of Los Altos Hills Sewer System Management Plan 8-1 1 • = Element 8:Capacity Management r (b) Desim Criteria: Where design criteria do not exist or are deficient, the agency should undertake the evaluation identified in(a) above( o e t o establish appropriate design criteria. (c) Capacity Enhancement Measures: The agency must identify the steps needed to establish a short- and long-term capital improvement plan (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.

This appendix includes the following information: 1. Capital Improvement Program,from Table 12-1 in January 2004 Sanitary Sewer Master Plan. 8.3 Capacity Evaluation Discussion The Town completed a Sanitary Sewer Master Plan in January 2004.This Master Plan includes a capacity evaluation and identifies capacity-related improvement projects. The Master Plan is a separate document from this SSMP, but this section of the SSMP summarizes the key capacity- related portions. The capacity assessment completed as part of the Town's 2004 Sewer Master Plan was based on hydraulic modeling of the Town's collection system under current and future design flows. The following sub-sections provide a brief summary of the capacity evaluation. Note that the Town has not experienced any sanitary sewer overflows due to hydraulic deficiencies in the sewer system. Hydraulic Model As a part of the Town's 2004 Sewer Master Plan, a spreadsheet hydraulic model was developed using Microsoft Excel to evaluate existing and future system capacity. The main objective of the spreadsheet model was to determine capacity of the sewers during various flow conditions. Refer to Chapter 8 of the Master Plan for a complete discussion of the model development. Approximately 140 critical pipe segments (i.e., the main trunk sewers), ranging in size from 6 to 12 inches in diameter, were included in the model. As discussed in previous sections of this SSMP, the Town discharges its flow to the Cities of Los Altos and Palo Alto. No pipes from these outside agencies were included in the model. The capacities of the Town's O'Keefe Pump Station and force main were addressed by the City of Los Altos in its 2005 Sanitary Sewer Master Plan. Town of Los Altos Hills Sewer System Management Plan 8-2 • 0 Element 8: Capacity Management Flow Estimates Sewage flows were estimated using unit sewage flow rates determined from dry and wet weather flow monitoring (conducted in October 2002 and February 2003, respectively) and parcel data. Water use data were used to confirm the results of the flow monitoring data. Refer to Chapter 7 of the Master Plan for a complete discussion of the model flow estimates. In each of the Town's sewersheds, existing and buildout average dry weather and peak,wet weather flows were calculated for every pipe segment included in the hydraulic spreadsheet Existing flows were calculated using.the currently connected parcels. Buildout flows were calculated using the total number of potential connections. This assumes all parcels will ultimately be connected to the sanitary sewer system. Peak wet weather flows were calculated using a peaking factor of 10 times dry weather base sanitary flow (BSF) plus an allowance for groundwater infiltration (GWI). This peaking factor is based on.the highest flows recorded during the wet weather flow monitoring period and is intended to represent a conservative estimate of wet weather flows based on the uncertainty of the flow monitoring data. Current and buildout average dry weather flow (ADWF) and peak wet weather flow (PWWF) are summarized in Table 8-1.

Information from the Sanitary Sewer Master Plan(January 2004),Table 7-3. b. ADWF=BSF+GWI c. PWWF=10 x BSF+GWI Capacity Evaluation Criteria The capacity evaluation criteria used in the Master Plan are summarized below. Gravity Pipe Criteria. For existing conditions, a pipe segment was"considered deficient if the flows exceeded the full pipe capacity. For buildout'conditions, a pipe segment was considered deficient if the flows exceeded 75 percent of the full pipe capacity. Pump Station and Force Main Criteria. The capacities of the O'Keefe Pump Station and force main were evaluated by the City of Los Altos in its Sanitary Sewer Master Plan. Estimated flows were compared to pump station-firm capacity (with one pump out of service) to determine the �i adequacy of existing pump station capacity. Force mains were considered to be inadequate if peak velocity exceeded 7 feet per second. Town of Los Altos Hills Sewer System Management Plan 8-3 • • Element 8: Capacity Management Capacity Evaluation Results The capacity evaluation identified seven manhole-to-manhole gravity sewer segments with potential capacity deficiencies under existing peak wet weather flows, and 70 segments with potential deficiencies under buildout peak wet weather flow conditions. These limitations are discussed in Chapter 9 of the Master Plan report. Many of the deficient segments are short, isolated reaches that may be deficient due to flat slope. These segments were considered unlikely to pose any significant risk of overflow in the near term. The City of Los Altos Sanitary Sewer Master Plan determined that the O'Keefe Pump Station and force main have adequate capacity. Recommended Capacity Relief Projects The Sewer Master Plan recommended 10 relief sewer improvement projects for the hydraulic deficiencies" identified in the capacity evaluation. Relief sewers were sized based on the following design criteria: • The minimum size for relief sewer is 8-inch diameter. • The relief sewers are sized to handle the flow in excess of 75 percent capacity in the deficient sewer. • The slope of the relief sewer is assumed to be a minimum of 0.2 percent, or match the slope of the deficient sewer,whichever is larger.C) (. Refer to Chapter 12 of the Master Plan for a complete discussion of the capacity evaluation recommendations. 8.4 Recommended CIP Appendix G includes a list of the recommended CIP projects. A phasing plan was developed depending on when the improvements would be needed. Since the Town's sewer system is considered to be in good condition (based on review of closed-circuit television inspection results for a representative sample of sewer pipes in the system conducted for the Master Plan), priorities were based on hydraulic deficiency. A priority of 1, 2, or 3 was assigned to each project. Priority 1 projects are anticipated to be needed in 10 to 15 years, including sewers that were identified as deficient under existing peak wet weather flows (note: due to conservative flow.criteria, none of these deficiencies were considered to pose a significant risk of near-term overflows). Priority 2 projects will be needed in the next 16 to 20 years. This includes sewers that have the greatest capacity_issues during buildout peak wet weather flows. A Priority of 3 was given to the remaining projects. Based on factors discussed in the Master Plan, the Town does not anticipate the need to begin the CIP prior to 2014. The Town plans to update the hydraulic analysis and Master prior to that date. The Master Plan includes a sewer connection fee analysis for funding the capital improvement program. The analysis determined the sewer connection fees that would be required to finance the CIP. Refer to Chapter 13 of the Master Plan for a complete discussion of estimated sewer connection fees and funding for the CIP Town of Los Altos Hills Sewer System Management Plan 8-4 • • • Element 9: MONITORING, MEASUREMENT, & PROGRAM MODIFICATIONS This section of the SSMP discusses parameters.the Town tracks to monitor the success of the SSMP and how the Town plans to keep the SSMP current.

How we communicate - on the phone, in writing, or in person -is how we are perceived. Good communication with the homeowner results in greater confidence in our ability to address the problem satisfactorily, less chance of having the homeowner prolong the claims process, and less chance of him/her exaggerating the damage done to their property. As a representative of your agency, you will occasionally have to deal with an angry homeowner. A sewer backup is a stressful event and even a reasonable homeowner can become upset should he/she perceive us as being indifferent, uncaring, unresponsive, or incompetent Although sometimes difficult, effective management of a sewage backup situation is critical. If it is not managed well, the situation can end up in a costly prolonged process with the homeowner. We want the homeowner to feel assured that we are responsive and the homeowner's best interest is a top priority. A Few Communication Tips 1. Give the homeowner ample time to explain the situation or to vent Show interest in what the homeowner has to say, no matter how many times you have heard it before, or how well you understand the problem. 2. As soon as possible, let the customer know that you will determine if the source of the sewer backup is in the public sewer and, if it is, will have it corrected as quickly as you can. Cj3. Acknowledge the homeowner's concerns. For example, if the homeowner seems angry or worried about property damage, saysomething like, "I understand you're concerned about the possible damage to your property, but a professional cleanup crew can restore the area, and if it is determined that the agency is at fault, the property owner has the right to file a claim for any reasonable repairs or losses resulting from this incident" 4. Express understanding and empathy for any inconveniences caused by the incident, but do not admit fault 5. As much as possible, keep the homeowner informed on what is being done and will be done to correct the problem. 6. Keep focused on getting the job done in a very professional manner. Focus on the problem without unnecessary small talk with the homeowner. 7. Don't find fault or lay blame on anyone. • • , . - - -- --- - 7 --- --Y SSO BackTu{ Response P[ib =-FG---_- - How to Use a'Hydroflusher to Clear a Line Blockage 2,1 - : Procedures for opening and cleaning a blocked municipal sewer line with a r8w high-velocity waterjet. Individual situations may be unique, but use these Y - basic procedures for any jetting project.. -Best tools: High-velocity flushing trucks. The jet may be a combination machine or a truck- or trailer-mounted jetter. Types of municipal sewer systems: • Sanitary sewers carry waste from homes and businesses to a municipal wastewater treatment plant • Storm sewers carry stormwater runoff to streams and rivers. Storm sewers carry heavier waste (sand, silt and gravel) than sanitary sewers. The size of the pipe and the type of sewer dictate cleaning procedures. ;: - `- :-;'::- .'. ' ',..- j# • Wear necessary PPE: Eye protection, coveralls, hardhat, work boots ._ S fe and work gloves- • Follow the CalTrans (,MUTCD) Traffic Control Manual and be aware of manhole hazards. • Follow all OSHA rules when entering confined spaces (manholes) • Proper tools for manhole lid removal: Gas tech, manhole lifter and traffic control • Never enter a manhole (confined-space) with the line under pressure because of the possibility of drowning or personal injury. • Prafes::________j- • Follow all safety rules Standards • Always consider every option available to hydroflush 'a municipal sewer system in a safe and cost effective manner. • Ensure that the residents and businesses within the work area or jurisdiction do not experience problems due to high pressure back ups or damage. • Effectively clean the sewer mains by incorporating these standard procedures of maintenance, experience, training and available tools to complete required day-to-day operations. 4' • 1 FG-2.1. How to Use a Hydfkitfte—r Locating the Blockage ' • • Determine the direction of flow in the system. Wastewater flows downhiltirra. STEP gravity-based sewer. - - -- 1 - - Use a sewer map and/or your familiarity with the area to identify the direction of flow OR remove a manhole lid and look into the invert. • Keep moving to the nearest downstream manhole until, the blockage is located. A manhole filled with wastewater or with a flow line above the sewer shelf is typically the problem area. • A full manhole means water and debris have entered the manhole, but because of a blockage downstream cannot drain away. • The blockage is normally between the first empty manhole (downstream) and the first full manhole (upstream). • • FG-2.1 How to Use a Hydroflusher 'r.l Page 3 • _ . -- Setting up the- ydra us ,er • Position the vehicle/sewer-cleaning equipment at nearest downstream manhole below the stoppage on the side nearer the blockage. - - - _STEP t • On steep lines where the downstream manholes are less than 5 feet deep, necessary precautions to prevent secondary overflows at downstream manholes must be taken. Form a containment barricade near the downstream manhole with use of sandbags, etc. SSP - • Position the water jet over the 1st empty manhole downstream of the blockage • If not already attached, attach 20'-25' of leader hose (a hose of a different color) to the regular hose — this serves:as a benchmark for insertion & retrieval (NOTE: A 5 leader hose helps prevent the hose from exiting the pipe prematurely & causing injury!) DO NOT use the alternative method of marking the jet hose five feet from the end! • Select a PENETRATING forward jet nozzle with a small angle(i.e. 15-degrees) for ySTEP. '; blockages. - i • Install a nozzle extension between the end of the hose & the nozzle to prevent the nozzle and hose from turning up a service lateral causing damage. • Lower-the hose, nozzle extension & nozzle into the manhole & into the pipe invert STEP 6 • Insert the jet hose through the Tiger Tail &tie the device in place to stabilize it. Note: failure to use a Tiger Tail or Roller Guide may result in the hose being damaged while flushing the main! • . Set up a vacuum truck/trailer or have a catcher available to completely capture and STEP 7 remove the debris to avoid future stoppages. This is a must when breaking mainline stoppages! l FG-2.1 How to Use a Hydreflusher Page 4 {• Hydroushing • Ensure that the hose, the nozzle extension and nozzle are inserted into the pipe STEP LI completely and the hose is protected by a hose guide device (i.e. Tiger Tail):, • Run the line with just enough pressure to reach the blockage. When-you-reech the blockage, the hose should stop. • Begin hydro flushing. Adjust water pressure as needed, but do not exceed 2500psi. • . Clean the sewer from the lower end to the higher end of the flow so that when the hose is retrieved, it works with the downward grade of the pipe and allows for more efficient cleaning of remaining debris. NOTE: In sewer lines where toilets have bubbled or overflowed due to high pressure back flushing, a lower pressure must be used to prevent additional backups ri = k • If the hose does not advance, pull back'on it and then let go (Be careful not to strain = your back!). Repeat the steps until the hose breaks through the blockage. =- k • If the hose breaks through and the line is still plugged, run the hose until you hit STEL ,k another plug, then repeat the steps again. • Clear the blockage by working from the lower end to the higher end of the flow. • Pull the hose back in a slow continuous speed to ensure that the line is beingcleaned sufficiently. Bringing the hose back too fast will leave the pipe with areas not cleaned, which is an unacceptable lever of cleaning. NOTE: Always jet the line a fewfeet at a time, returning the debris to the manhole — completely remove debris so further blockages are not created downstream! Pulling heavy debris is time-consuming and laborious, and if not done properly can cause the - - hose and nozzle to be buried and stuck. Then you may need to dig up the sewer. STEP 5:- - • The debris is pulled to the manhole by the water flow and the returning hose and nozzle. Allow the hose to enter slowly on the initial passes and pull the hose and nozzle back occasionally to prevent them from exiting a defective pipe or becoming buried in debris. • Remove the debris using the vacuum portion of the combination truck, or a debris removal hand tool. Anytime you hydro flush a sewer, remove the debris completely to avoid future stoppages. If this can't be done, then drag the debris into a high flow trunk main to prevent a stoppage from occurring downstream. • Always look into the bottom of the manhole for the amount and type of debris being pulled from the pipe to determine the number of passes and the length of the passes needed to clean the sewer effectively. • 1 Once you hear or see the rush of the water, turn off the pressure until the water level 5 drops in the line. Once the flow is tack to normal, run the hose up to the next manhole • to insure that the line is free of all blockages, then pull the hose back. Check the upstream manholes to make sure the line is running. Always rewind the jet hose with the water pressure on to avoid flattening the hose. NOTE: Always turn down the water pressure once you see the leader hose—Run hose ;STEP= ;,- until spray from the nozzle fills the pipe, then shut down the water. Shutting the water down prematurely will leave material at/or upstream from the manhole causing another blockage in a very short time. - - ..

It can be seen as a gentle flexing of the rod—twisted up to 90 degrees. Excessive Torque: Develops when the tool is not pulled away from the material it is bound in. It can result in rod damage and downtime in the field. It can be seen as rods twisting past 180 degrees, making the guide hose twist slowing down the reel and making the engine work too hard. Testing for Rod Damage: Stretch 50-100 feet of rod out on a flat surface. Damaged rods will appear twisted, won't lie flat and bends will be obvious.

' ; SSQIBackcup Response Plan' FG Containment Procedures 3 Protection of the public's health and a safety is a top priority! The overflow must be contained. Containment becomes more difficult if the overflow reaches the storm drain system or drainage channel since the overflow can rapidly contaminate receiving waters such as creeks, streams, rivers, and other water bodies. During dry weather, the storm drain system can be used to store the overflow if it can be plugged downstream of the overflow or if the downstream storm drain pump station canbe deactivated.

Estimate the time that the overflow has been occurring .(Remember: the overflow was probably flowing before it was reported). 3. Each residence contributes about 240 gallons per day or about 10 gallons per hour. Multiply the number of residences by 10 and by the number of hours. This gives you the number of gallons. NOTES: - a. Remember that 10-gallons per hour is an estimate. This number will be higher during peak water usage times and lower during low water usage times. Take this into account when estimating the overflow volume. b. This is a conservative estimate because stoppages rarely stop all of the flow. • . • ; .

Ed Euyen, Civil Engineer, P.E. No. 33955, California developed this sanitary sewer overflow table, for County Sanitation District 1. This table is provided as an example. Other Agencies may want to develop their own estimating tables. • • (t-Th SSO/Backup:Response Fran FG Determining Overflow Rates From a Maintenance Hole: 6.4 I Flow From a Maintenance Hole Pick Hole Tables side A The formula used to develop Table 3 is Q=CcVA, where Q is equal to the quantity of the flow in gallons per minute, Cc is equal to the coefficient of contraction (.63), V is equal to the velocity of the overflow, and A is equal to the area of the pick hole. If all units are in feet, the quantity will be calculated in cubic feet per second, which when multiplied by 448.8 will give the answer in gallons per minute. (One cubic foot per second is equal to 448.8 gallons per minute, hence this conversion method). Example Overflow Estimation: The maintenance hole cover is in place and the height of water coming,out of the pick hole seven-eighths of an inch in diameter (7/8") is 3 inches (3"). This will produce an SSO flow of approximately 4.7 gallons per minute.

The Town is not responsible for clean up charges or damages caused by blockages in the property owner's sewer lateral or caused by code violations. At this time, the Town is investigating the cause of the loss and does not assume liability for damages. However, if our investigation determines the Town is responsible for this incident, the costs you incur for reasonable and necessary clean up will be included in the settlement of your claim. Regardless of whether you or the Town is responsible for the loss, it is up to you to arrange for the repair of your property and to present a claim for consideration. You or the property owner should immediately contact a firm for clean-up of the affected areas.

Per.State.Water Resources Control Board Order No. 2006-003, all agencies that own and operate collection systems greater than a mile, must have an emergency overflowresponse plan(EORP).in place. The Town of Los Altos.Hills owns about 60 miles of"collection system, which is contracted to Veolia Water to manage and operate.,The overflow response procedure is intended to outline the minimum steps to be taken by collection system personnel. The procedural steps indicated are intended'tb identify baseline,requirements: All Steps will::not:apply inevery:case.;;Additional steps maybe necessary in=somecases. Theprocedures:must-be.used-based on experience with the collection system and::applicable regulatory provisions. it is the goal of this document to establish and follow guidelines to enable personnel to recognize, assess and remedy any Sanitary Sewer Overflow(SSO) in an expedient manner.---Further,-it is-intended-to-provide-steps-to:ensure-minimal----. environmental impact to receiving waters of the United States of America, and to minimize exposure to the general public and to private property. i The developed plan includes the following items: • Proper notification procedures. • Appropriate`response'to sanitary sewer overflows (SSOs). • Procedures to report and notify appropriate regulatory'agencies and potentially affected.entities. . • Procedure °ensure that appropriate to staff-and contractor personnel ate aware of arid:follow an,emergency response-plan and;areappropriately trained. • A program to ensure that all-reasonable steps are taken to'contain and prevent the dischargeof untreated and partially treated wastewater to watersof the United States: . The Town of Los Altos Hills and Veolia Water have implemented a proactive approach in preventing SSOs from occurring. Our approach includes the following: • Aggressive cleaning and inspections.of troubled areas within the system; • A Computerized Maintenance and Management System (CMMS), with this c 1 integration, the Town can.easily track and update troubled spots within the database system for automated scheduling purposes • • • 1 A • of CMMS in a structured approach for the purpose of (2') ImplementationPP PrP scheduling, monitoring, evaluating and reporting the collection system performance; • Inspections of lift stations for redundancy and to promote reliability and enough capacity to convey peak wet weather flows; - - - . 6.1 - Description of the Collection System The collection system composes of 58.4 miles of gravity sewer mainlines and 0.3 miles forcemains and two lift stations..These pipes are predominantly made of Vitrified Clay Pipe (VCP)and range in diameter from" 6" and the average age of pipes within the system.is E years. 6.1.1 - Sewer Pipelines- The system consists of 80% of 6-inch pipelines, 15% of 8-inch pipelines and 5% other pipe sizes. Dry weather related Sanitary Sewer overflow'incidents occur predominantly in the 6-inch diameter pipelines due.to root intrusion. 6.1.2 - Sewer Lift Stations • . There are 2 lift stations in the collection system,each with at two pumps. The Town of Los Altos Hills and Veolia-Water's goal for each and every lift station is to have enough capacity to convey average and •eak flows, improve the reliability and also redundancy of the system. 6.2 - Sanitary Sewer Overflow Potential Sites and Conditions All-dry weather related Sanitary Sewer Overflows predominantly,occur within the 6-inch and 8-inch diameter pipes. • 6.2.1 - Blockage :,.:: _: •..:._ A SSO will occur due to blockage of the sewer main by deposition of debris at a • section of the pipe or manhole thereby releasing a built-up pressure of partially treated waste water at the manhole located upstream from the blockage. Lack of maintenance of Lift station could lead to blockage at pumps which in turn prevent the pumps from circulating waste water from suction or discharge head section of the pumps due to the accumulation of debris. 6.3 - Prevention Methods The Town of Los Altos Hills and Veolia Water are committed to preventing Sanitary Sewer Overflow before they become a threat to human health. The incidence of SSO has continued to reduce drastically through the use of Veolia Water's Underground Asset Management (UGAM) approaches to manage the system. • • ' 6.3.1 - Preventative Maintenance/Hot Spot Cleaning The cleaning program consists of preventative maintenance which includes hot spot cleaning and'service call cleaning programs: Annually approximately 32 miles of gravity sewer lines are flushed by Hydro jetting and mechanical rodding methods. The preventivemaintenance program includes setting.the cleaning frequencies for various diameters of pipes and hot spot locations. All segments with.a.repeat period of less than a year are categorized as "hot spots." The methods below-are procedures for using the traditional hydro flushing equipment: Hydro Flushing Procedure 1. Locate the hydro flushing vehicle at the downstream location of the affected area. 2. Review the cleaning process steps with the Field Crew. , 3. Employ the spinning nozzles to the Jetter hose, flight and nozzle assembly. 4. Engage the water pump and build pressure to 2000 'psi. 5. Send nozzle forward to the upstream access manhole. 6. Tum off the water and conduct an inspection of the upstream manhole to ensure that you reach the location. 7. Employ thevacuum tubes to collect the debris and material. 8. Energize the nozzle to1,800 psi and 8;0 gallons per minute. 9. Slowly return the nozzle back at 60 feet per minute rate. 10.Monitoringthe footage counter determine when you are 10 feet from the downstream manhole. 11.Stop hose and reduce to idle pressure and water flow and turn the pump .. .. ,.�.: : ... .. 12.Using the vacuum truck remove any accumulation from the downstream manhole. 13.Observe the Jetter hose for excess grease and roots. If present repeat the process until clean. 14.Review cleaning process with field Crew for training:purposes. Document any changes in the standard operating'procedure. Provide additional training based on the quality of the work performed. 15.Update standard operating procedures and provide training on a yearly basis. Rodding equipment usually consists of rodding machine, cables and a cutting head.There are many different cutting heads designed for different types of drain lines that alleviate certain types of sewer and drain line stoppages. The cutting head attaches to the end of a cable that is inserted into the sewer or drain line. The cables are sectional and come in different lengths and diameters for different types of lines and stoppages. All cables look like long springs. The rodding machine consists of a motor and clutch to grab and spin the cables and cutting 411 • head at a low speed but at a very high torque. The spinning cutter head will cut through the different stoppages in an attempt to open the line. The coils in the cable help to feed the cable into the sewer line as the cable spins and to snare the debris stopping the line to help remove the debris from the line. Jetting is a term used to describe a method used to open and scour drain lines with the use of high-pressure water. A Jetter uses water pressurized between 1200 to 1800 psi to cut through small root fibers, dirt, organic debris, grease and oil. Jetters are commonly used in restaurants and auto garages where grease from kitchens and oily sludge from automobiles collects in drain lines. While rodding can open a drain line,coated with grease or oil, only a Jetter can scour the line removing the majority of the grease and Oil. Procedure: 1. Prior to operation of any of the accessory equipment on the Vactor truck, .. ensure that an adequate traffic safety plan has been implemented, that the parking brake is on and wheels chalked, the Power Take Off(PTO) is on, and that the proper PPE is being worn. 2. Using proper lifting techniques open the manhole in which you will be inserting the jet rodder. 3. Extend the hose reel out to its working position. Release the hose reel swivel lock, and swivel the hose reel to a position that allows the straightest line for the hose to travel from the reel to the pipe. Once in position, engage the swivel lock. 4. Using the hose reel control lever-, extend enough hose out to enable you to place the head (tool) into the lin&(pipe)lo,be jet rodded. , 5. Place the hose protector(tiger tail) so that it is between any,surface that makes contact with the hose, and the hose itself. 6. Turn the throttle switch on, on the hose reel control panel. 7. Open the water valve, by tuming'the lever into the vertical,position, 8. Turn the jet rodder on by flipping the jet rodder toggle switch tO the "up" position. 9. Gradually increase the pressure using the throttle up switch. Watching the travel of the hose, control the speed and amount of hose you let out with the hose reel control lever. • • • fl 10.When retrieving, or bringing the hose back in, use the hose reel control lever to control the speed of retrieval-making sure it is winding back on the hose reel properly. 11.When the head is approximately. 10ft. from the man-hole (as indicated by the change of color in the hose-orangeto black) decrease the throttle;flip the jet rodder•toggle switch tothe down (off) position, and close the water valve by'tuming the lever to the horizontal position. 12.Reel in the hose until the head (tool) is exposed; Finish reeling in the hose, securing the head in the hose reel guide. 13:Swivel the hose reel back into its starting position,.engaging the swivel lock and retract it back in: • JET RODDER HEAD/TOOL: Abnormal Conditions . 1. -Attempt-to-free-the-head/tool-under-power-,-moving-it-in-and-outs 2. If unable to dislodge the head/tool under power, turn off Jet Rodder, isolate water supply to Jet Rodder and relieve tension in the high - pressure water hose by letting the reel out. 3. If the head/tool is stuckclose.to the inlet,.:use a.shovel.of appropriate length (so that your person is above ground and no part of you is . breaking:the plane of the manhole) and keeping your:body in a . controlled/balanced position attempt to dislodge head/tool: 4: If unable to dislodge head/tool with moderate pressure on the shovel or tool, notify your supervisor, and cut the high-pressure hose at the manhole-street level.. . 5. At..supervisor's instructions, initiate procedures for a confined space entry to attempt to retrieve the head/tool. 6. If Still not able to retrieve the head/tool, the decision will be made to prepare for and emergency excavation to retrieve the head/tool. • The cleaning methods Includes utilizing traditional hydro flushing of sewer pipelines, root foaming to facilitate the removal and growth of deep rooted plants, and employment of biodegradable products to mitigate grease and grit accumulation in sewer pipelines and lift stations. i The Town completed a Root foaming cleaning method in 2011 and was subcontracted out to Dukes Root Control: Duke's certified applicators use specialized equipment to fill the affected sewer pipe with thick herbicidal foam. • • Q)Foam with a thick, shaving cream consistency like Duke's is essential to adhere to roots and travel up the laterals. Duke's exclusive dense foam also packs more active chemicals in the spaces between the bubbles and has a longer retention time. After inserting the hose from manhole to manhole, the foam is released, compressing against pipe surfaces, penetrating cracks, joints, and connecting sewers. Roots are killed on contact, decay naturally and slough off.-Duke's applications prevent root re-growth for 3-5 years. Duke's uses the most effective chemicals and methods. . Duke's continually researches the most effective products available. Razorooter Il® is the only diquat-based herbicide registered by the U.S. Environmental Protection Agency(EPA) for controlling nuisance tree roots in sanitary sewer line collection systems and received a,classification of"evidenceof non- carcinogenicity for-humans".(USEPA Diquat R.E.D. Facts; July 1995).Duke's is able to provide safety for applicators, workers downstream, homeowners, and treatment plants. Rootsare killed on contact inside and outside pipe walls, and the foam penetrates through wye connections to kill roots in lateral lines. Trees and other above ground vegetation are not harmed. In addition, no jet trucks or other potentially damaging equipment are used. • 6.3.2 Condition Assessment Condition assessment of the collection system includes smoke testing, CCTV inspections survey, dye testing, flow monitoring and manhole inspections. Veolia Water is contracted to complete 18000 feet of cctv each year and also videos the mainline after the stoppage. 6.3.8 -Training and Equipments Maintenance .. - _. All Collection System employees are appropriately trained to implement all components of the Sanitary Sewer Management Plan. Operations and management team members are required to comply with all aspects of the emergency response plans. Veolia Water's operators are crossed-trained on how to respond to sanitary sewer overflow, estimate SSO volume calculation etc. Our firm promotes cross- training of our collection system O&M team in other projects to stay abreast of industry. We also conduct initial and annual refresher training, on procedures to notify, respond to, report and impact mitigation of SSO events, through seminars organized by California Water Environmental Association and other notable associations in California. Drills are conducted to make sure all employees are properly equipped and efficient during an overflow incident. The collection group is supported and trained regionally by Veolia Water's Underground Asset Management(UGAM) group. • Our Collection System Field Crew performs daily inspections of equipment, such as the CCTV truck, cameras, combo hydro flushing trucks, computers, spare parts, portable pumps, generators, forklifts, traffic control equipment, etc. This is done to ensure that equipments are operating properly, with any found deficiencies reported to the Collection System Supervisor and Manager. They are then responsible for coordinating with local vendors, to implement the necessary repairs. 64 - Overflow Emergency Response This section describes the emergency response plan procedures identified by the order set by state•and local RWQCBs, 6,41 Notification The method used to notify the City of an occurrence of a sanitary sewer overflow include observation by the public, City employee, receipt of an alarm and physical observation by field employees during normal business hours. 642- Receipt of Information,Regarding an Overflow When a member of the public notices an overflow or blockage, they report such Ti-fdidefibito-the-Town located at 26379 Fremont Road, Los Altos Hills, CA 94022, and City's telephone number for reporting Sanitary Sewer issues is 650- 941-7222. Normal business hours are Monday through Friday from 7:00 AM to 4:00 PM. Service calls received during normal business hours are taken immediately and passed on from the call center to the Collection Field Crew who respond within 60 minutes of an SSO event.

They decide what approach-will result-in.minimal,damage either by clearing the blockage first or initiating.spill containment measures. Thefirst responder must report the severity of the overflow incident to Veolia Water Field Supervisor and Collection Manager. The field crew logs all information requested on a Service Call form,. Information from each call shall be placed on a separate Service Call form. Adequate information from the reporting party is attempted to be obtained including the name, address and telephone number of the person who reported the service call and the nature of the problem. . The field crew looks at the maps to determine location of sewers in the area of the reported overflow or problem. Upon arrival at the site of problem, look for .. apparent overflows. If an overflow or surcharged sewer main is located, check downstream manholes until a dry'manhole.(normal'flow or less)is located. If a second person is needed to assist in clearing a stoppage; the responded should contact a second person. Contact homeowner or person who reported the problem. Where sewage has overflowed out of a manhole or cleanout, contain the area and collect all flow, paper and solids as possible. Flush manhole steps and shelves to clear debris whether or not overflows have occurred. 6.5.1 - Restore Flow The Field Crew will set up on downstream manhole location with little or no flow. Utilizing combo hydro flushing equipment,the sewer mainline will be jet cleaned from downstream to upstream direction to hit, clear and vacuum the blockage from the pipe. Additionally,the Field Crew will observe when flow is returned to normal scouring velocity.Determine if other personnel are necessary, contact them if needed.Make. (2) arrangements for other personnel to bring additional equipment in the event of mainline stoppage • • 6.5.2 -Spill Containment Significant amount of effort must be geared toward spill containment by the Field Crew to recover as much spills as possible from creeks, storm drain system, ground surface, gutter and side walk.. The first responder should attempt to contain as much of the spilled sewage as possible using the following steps: • Determine the flow path of partially treated wastewater. • Contain the spill.volume•flowing into:thestorm drain_system. • Plug;storm-drain manholes,.catch basins,,inlets and culverts with sandbags, air plugs and plastic mats.inorder to-containthe spill. • Notify theappropriate regulatoryagencies if a spill is discovered in a creek. • Mitigate the direct impact on creeks by damming. • Recover and capture as much sewage as possible by pumping directly to downstream manhole. 6.6 - Overflow Cleanup Procedure for Small and Large Spill Overflow clean up procedures-involve the use of the equipment identified in the contingency-plans in-order to-prevent-public contactand-exposure-to-spill-site. This serves to reduce the potential for human health hazard and environmental impact. Portable pumps, storage drums, vacuum trucks, brooms; shovels and other tools are available to'Field Crew.to facilitate cleaning:activities.(0 Captured spill.and•recovered volume will be accounted for,and all spills to the ground surface will be washed down. . 6.6.2-Traffic arid Crowd Control Traffic and`crowd control measures vary based on the size and potential impact of the overflow event. When appropriate, local police, fire department, and Town contacts should be notified to•aide:in addressing traffic and:crowd control issues. The`steps below shall be taken when dealing with'traffic issues pertaining to spill volumes: • Small Spill (Less than 1,000 gallons): • Set up traffic cones to direct traffic from spill area. • Use staff personnel to control traffic and pedestrians. • Medium Spill (1,000 gallons to 10,000 gallons): • Contact member agencies, as needed. • Perform lane closures, as needed. • Close any affected entrances or exits from all public and private facilities. • Place proper signage for any lane closures including contaminated area signs. Inform local law-enforcement and/or fire department of lane/road ��! closures and traffic control. • • • • Use caution tape and barricades to protect pedestrians from contaminated areas. • Large Spill (Greater than or equal to 10,000 gallons): • Contact member agencies, as needed. • Inform local police and sheriff departments of any law enforcement needed for road closures and traffic control. • Inform local fire department of lane and road closures. • Delegate the responsibilities of informing the public of hazards to member agency team members.. • Use signage to inform public of potential hazards to public health and safety. • Block public access to hazards using barricades, cones and caution tape. Omit flushing and sampling during heavy storm events with heavy runoff, where' flushing is not required and sampling would not provide meaningful results. 6.6.3 - Creeks/Water Bodies and Easement Subdivisions The cleanup procedure forspills into waterways includes the following steps: (2) • Notify the California Emergency Management Agency/Department of Fish and Games, as soon as possible. • Determine if the creek and other affected,water body,,is safe to enter. • Set up traffic control measures in order to prevent public access to beaches and creeks. •. Contain and recover as much.of the spill:as.possible • If possible, block the.creek downstream of the contaminated flow, based on - visual evidence. • Inform the local fire department of lane and road closures. • Delegate the responsibilities of informing the public of hazards to member agency team members. Cleaning procedures for spillsassociated with easement subdivisions follow the traffic and crowd control clean-up procedures specified for small and large spills. 6.6.4 - Overflow Volume Calculation Methods for Estimating,Spill Volume A variety of approaches exist for estimating the volume of a sanitary sewer spill. This sections below documents the three methods that are most often employed. The person preparing the estimate should use the method most appropriate to the sewer overflow in question and use the best information available. • • Method 1: Eyeball Estimate The volume of small spills can be estimated using an "eyeball estimate". To use this method imagine the amount of water that would spill from a bucket or a barrel. A bucket contains 5 gallons and a barrel contains 50 gallons. If the spill is larger than 50 gallons, try to break the standing water into barrels and then multiply by 50 gallons. This method is useful for contained spills up to approximately 200.gallons. Method 2: Measured Volume The volume of most small spills that have been contained can be estimated using this method. The shape, dimensions, and the depth of the contained wastewater are needed. The shape and dimensions are used to calculate the area of the spills and the depth is used to calculate the volume. Common:Shapes and Dimensions • • RECTANGLE CIRCLE • TRIANGLE 'R�rtR a t,;.t.

Step 2 Measure or pace off the dimensions. Step 3 Measure the depth at several locations and select an average. Step 4 Convert the dimensions,including depth, to feet. Step 5 Calculate the area in,square feet using the following formulas: Rectangle: Area = length (feet) x width (feet) Circle: Area = diameter(feet)x diameter(feet) x 0.79 Triangle: Area = base (feet)x height(feet) x 0.5 Step 6 Multiply the .area (square feet) times the depth (in feet) to obtain the volume in cubic feet. Step 7 Multiply the volume in cubic feet by 7.5 to convert it to gallons Method 3: Duration and Flowrate Calculating the volume of larger spills, where it is difficult or.impossible to measure the area and depth, requires a different approach. In this method, • • separate.estimates are made of the duration of the spill and the flowrate. The Cr) methods of estimating duration and flowrate are: Duration: The duration is the elapsed time from the time the.spill started to the time that the flow was restored. Start time: The start time is sometimes difficult to establish._ Here are some approaches: Local residents can be used to establish start time. Inquire as to their observations. Spills that occur in rights-of-way are usually observed and reported promptly. Spills that occur out of the public view can go on longer. Sometimes observations like odors or sounds (e.g. water running in a normally dry creek bed) can be used to estimate the start time. Changes in flow on a downstream flowmeter can be used to establish the start time. Typically the daily flow peaks are "cut off' or flattened by the loss of flow. This can be identified by comparing hourly flow data during the spill - event with flow data from prior-days. Conditions at the spill site change-:over time. Initially there will be limited deposits of toilet paper and other sewage solids. After a few days to a week, the sewage solids form a light colored residue. After a few weeks to a month, the sewage solids turn dark. The quantity of toilet paper and other materials of sewage origin increase over time. These observations can be used to estimate the start time in the absence of other information. Taking photographs to document the observations can be helpful if questions arise later in the process. It is important to remember that spills may not be continuous. Blockages are not usually complete (some flow continues). In this case the spill would occur during the peak flow periods (typically 10:00 to 12:00 and 13:00 to 16:00 each day). Spills that occur due to peak flows in excess of capacity will occur only during, and for a short period'after, heavy rainfall. : y End time: The end time is usually much easier to establish._- Field crews on-site • observe the "blow down" that occurs when the blockage has been removed: The "blow down" can also be observed in downstream flowmeters. Flow Rate: The flowrate is the average flow that left the sewer system during the time of the spill. There are three common ways to estimate the flowrate: The San Diego Manhole Flowrate Chart: This chart, shows sewage flowing from manhole covers at a variety of flowrates. The observations of the field crew can be . used to select the appropriate flowrate from the chart. If possible, photographs are useful in documenting basis for the flowrate estimate. , • . H . . 40 Flowmeter. Changes in flows, in downstream flowmeters can be used to estimate the flowrate during the spill. Counting Connections: Once the location of the spill is known, the number of upstream connections can be determined from the sewer maps. Multiply the number of connections by 200 to 250 gallons per day per connection or 8 to • 10 _ •, . gallons per hour per connection. For example: ' 22 upstream connections x 9 gallons per hour per . . connection = 198 gallons per hour/60 minutes per hour --= 3'.3gallons,Per_minute - ' . • Spill,Volum0: Once duration;Ond flowrate have been estimated, the volume of .., the spill is the product of the duration in hours or days and the flowrate in gallons per hour or gallons per day. • ,. For exampTe: Spillstart time = 11:00 ) - . Spill end time = 1400 • ' Spill duration = 3 hours , . 3.3 gallons per minute x 3 hours x 60 minutes per hour = 594 gallons • . _ . - -- - •__ ( ) - . . • 6 Manhole Overflow Flowrate Guide Reference Sheet for Estimating Sewer Spats laktk City of San Diego from Overflowing Sewer Manholes Wastewater Collection Division Metropolitan Wastewater Department An estimates are aladated in gallons per agnate&pa 1619)654-4160 cWrIV.V'''-"-7.--'77-'7.` 7----77-,,---.•-7-----77 4.3.TAlir,„„Xt7:4Aii-V5', 7-..z.2- 1, ' -46.--A0.0....7)1;_siii„. .......... __ . ....,4,,,........,..„4„ -,.........;-.-A, ‘. --,1:41-07.---:-: ......*..,..„-_-.__.„- --.,.--,. ....4,...-..- , .„ -,...,sf-r—•-, . . :,..„. .4 .w.,..77-.17-...„------,------ .-_,....:0.--,.;!:- .,:,-g . ---a--,- ,-„..-c.. ,...A-i ,r...0:: ,, ___ ,.•"..,..4 -- '4,-wt.- '-or ' - "...- --'"...,r"-3:s; 'nk = -4' , - - _4.1tk. , ''''-' •="14 _.„3.."1.44,'.3'3'3 .....-3".-."r - 111,:---"'-`'.,. -,: _,,, ..,.-. 1,.1;3- , ,:0 . , _ -,_- ''--- „_-,--3 --;11, .L4-7.-7-::'-:;-:'-'•''.... f .74.''.:.,%:.'''A.,14' .' 7,2L.c."-`1, "-7,-77.1--.1.4, -17;-41;7-**;-'-'1.4-7 r7e2:7-:--! * --it:71i;Tf727‘..:;71;3',-.:.;;-;-;... --- =-,1-7.4•WVP . 1: . ,,--, .; 4-4Z-7,:+:-:::::',::;-7' - '7 •.777--,,.- `..- -'''-%::.i-rf'':-.'-.

Reporting and documentation requirements vary based on the type of SSO. There are three categories of SSOs as defined by the SWRCB: 9 Category 'I -All discharges of sewage resulting from a failure in the City's sanitary sewer system (mains and lower laterals) that: A. Equal or exceed 1,000 gallons. B. Result in a discharge to a drainage channel and/or surface water C. Discharge to a storm drainpipe that was not fully captured and returned to the sanitary sewer system. • Category 2 -All other discharges of sewage resulting from a failure in the City's sanitary sewer system (mains and lower laterals). • Private Lateral Sewage Discharges - Sewage discharges that are caused by blockages or other problems within a privately owned lateral. • 6.7.1 - Internal Reporting Procedure .. Once Field Crews are done with completing their work orders in.the field and documenting the SSO events, they.0 load their work order p to a master databa se. Veolia Water is not required to report any SSOs occurring from a private lateral pipe, but it always ensures that the main_sewer lines are cleaned and also advice such residents to'contact their plumber for the cleaning of their Lateral service pipelines. The home owners are also referred to the Town on how to obtain grants for faulty lateral line repair. 6.7.2- External Reporting Procedure All external reporting is done by the Town. The California Integrated Water Quality System (CIWQS).electronic reporting system is to be used for reporting SSO information to the SWRCB:whenever possible. 6:7.2`.1 .-'.SSO Category 1 that Reaches Water of the State If a Category I.:SSO results,in"a discharge to waters of the State (a drainage channel or surface water, if not fully recovered), the,followingreporting requirements apply:_,. . .. • Within two hours of notification of the spill event, the Town's legally responsible officer will: • Prepare an initial electronic report using RWQCB Electronic:Reporting System. • Notify the OES (and obtain spill number for use in other reports). • Notify the Contra Costa County Health Service Agency. • Within 24 hours of notificationof the spill event, the Town's legally responsible officer, or their designee, will certify to the RWQCB . This notification, as discussed above, should be made using the RWQCB Electronic Reporting System: • Within 3 business days of the spill event, the Towns legally responsible officer, or their designee,will be responsible for certifying the initial report using CIWQS. • Within 15 calendar daysof the conclusion of SSO response and • remediation, the Town of Los Altos Hills legally responsible officer, or their designee, will be required to submit the.Final Certification to the RWQCB. The town's legally responsible officer, or their designee, will also append additional information to thecertified report, in the form of an attachment, if needed, at any time. 6.7.2.2 - SSO Category 2 Within 30 calendar days after the end of the calendar month in which the SSO occurs, the.Town's legally responsible officer will submit an electronic report to SWRCB (using CIWQS). • • The Town of Los Altos Hills legally responsible officer, or their designee, will then (?) 9 Y certify the report. 6.7.2.3 - Private Lateral Sewage Discharges All sewage discharges that meet the above criteria for private lateral sewage discharges may be reported to the.Online SSO Database, based upon the City's discretion. • If a private lateral sewage discharge is recorded in the SSO Database, the City must identify the sewage discharge as occurring and.caused by a private lateral, and a responsible party(other than the City) should be identified, if known. 6.7.2.4-- No Spill Certification If there are no SSOs during a given calendar month, the Public Works Senior Supervisor or Public Works Supervisor will be required to submit an electronic report that the City did not have any SSOs:. The Town of Los Altos Hills legally responsible officer, or their designee,-will be required to certify the report within 30 calendar days.after the end of each:. calendar month. - 6.7.2.5 - CIWQS (is not available) In the event that the CIWQS system is not available for reporting, the Town's legally responsible officer, or their designee, will be,required to fax all required information to.the RWQCB office, at the RWQCB fax number of(510) 622-2460, in accordance with the time schedules identified above. Insuchevent, the Towny will submit the appropriate reports using CIWQS as soon as practical. 6.8 - CIWQS Online Database The SSO database is used to collect and store an enrollees,(defined as an agency which is covered under the Sanitary Sewer Order)•facility and organizational information (collection system questionnaire).and details of all SSOs which occur from an enrollee's sanitary sewer'system (SSO reports). All of the information collected in the SSO database is entered by enrollees; state and Regional Water Board staff cannot enter or modify any information in the SSO database. The SSO database is accessed through the CIWQS website, which is'the State Water Board's regulatory'and water quality information management system. Enrollees will be assigned a CIWQS account to access the SSO database. The implementation of the SSO database has been phased-in throughout the state on a regional.basis as discussed below. Access to the SSO database allows enrollees to complete the Collection System Questionnaire and submit.SSO reports as required by Sanitary Sewer Order. The Sanitary Sewer Order requires enrollees to complete the collection system 4111 questionnaire within 30 calendar days of receiving their CIWQS user ID and password. • 6.8.1 - Online Reporting Once a legally responsible official (LRO) has received their CIWQS user ID and password, the enrollee can register additional staff for individual access to CIWQS for submitting Agency information to the SSO database. Instructions regarding this registration process are available on the CIWQS Help Center webpage. These accounts will allow controlled and secure entry into the SSO Database. Additionally, within 30 days of receiving an account, and prior to recording SSOs into the SSO Database, the City-must coMplete the "Collection Systein Questionnaire,"which collects pertinent information regarding a City's collection system. The "Collection System Questionnaire" must then be updated at least every 12 months. 6.8.2- Minimal Reportable Data At a minimum, the following mandatory information must be included prior to finalizing and certifying a SSO report for each category of SSO: SSO-Category 1 • All information listed for Category 2 SSOs. • Estimated SSO volume that reached (or did not reach) a surface water area or drainage channel. • Volume recovered from a storm drain. •,Esfimated SSO amount recovered. • Response and corrective action taken. • If samples were taken, identify which regulatory agencies received sample results (if applicable). If no samples were taken, the "NA" must be selected: • Parameters that samples were analyzed for(if applicable). • Identification of whether or not health warnings were posted. • Beaches impacted (if applicable); if no beach was impacted, then "NA" must be selected. • Whether or not there is an ongoing investigation. • Steps taken, or planned, to reduce, eliminate, and prevent re-occurrence of the overflow and a schedule of major milestones for those steps. • OES control number(if applicable). • Date OES was called (if applicable). • Time OES was called (if applicable). • Identification of whether or not County Health Officers were called. • Date County Health Officer was called (if applicable). • Time County Health Officer was called.(if applicable). • • • SSO Category 2 Q**) • Identify the location of SSO by entering the GPS coordinates. • Identify the region, that is, the applicable Regional Water Board area of jurisdiction, in which the SSO occurred. • Identify the county where the SSO occurred. • Document whether or not the SSO entered a drainage channel and/or impacted a surface water body. • • Document whether or not the SSO was,discharged to a storm drain pipe that was not fully captured and returned to the sanitary sewer system. • Estimated the SSO volume in gallons • Identify the SSO source (manhole, cleanout, etc.). • Identify the SSO cause (mainline blockage, roots, etc.). • Document the time of the SSO notification or discovery. • Document the estimated operator arrival time. -- - • • Document the SSO destination. • Estimate the SSO end time. • Upon SSO certification, the SSO database will issue a final SSO • Identification (ID),Number. • Private Lateral (2) • •All information listed above (if applicable and known). • Identification of sewage discharge as a private lateral sewage discharge. • Responsible party contact information (if known). • 6.9 - Certification of Final Report All final reports must be certified by an authorized person, as-required by Provision J of the Order. Registration of authorized individuals, who may certify reports, will be done in,accordance with the CIWQS' protocols for reporting. The general work flow for the SSO database, which is utilized by the City to comply with the SSO reporting requirements, uses the process that is discussed in the paragraphs that follow. The Town must report two types of information into the SSO database: sanitary sewer system/agency characteristics (collection system questionnaire), and spill details (SSO report). The Town's collection system questionnaire was completed before any SSO reports were submitted. Additionally, the collection system questionnaire has been, and will continue to be, updated annually. •All SSOs from the Towns sanitary sewer system must be reported in the SSO database. The deadline for submittal of a SSO report depends on the classification of the spill, i.e. Category 1 (greater threat) or Category 2 (lesser • threat). For a Category 1 spill, the enrollee must submit an initial, uncertified report of the spill as soon as possible but no later than three business days after • • (' _ being made aware of the SSO. The final, certified report for a Category 1 spill must be submitted within 15calendar days of the conclusion of SSO response activities. For a Category 2 spill, the enrollee must submit a final, certified report (noinitial, uncertified report required)within 30 calendardaY s after the end of the calendar month in which the SSO occurred. The process of entering information into the'SSO database begins with the enrollee'specifying the pertinent sanitary sewer system. The collectionsystem questionnaire is an on-line form which contains questions regardingthe relevant characteristics of the City's sanitary sewer system.and agency. After initial login, the first major ts k an enrollee needs to perform is.. completing the collection`system questionnaire A new collection system questionnaire is accessed through the "Collection System Questionnaire" link on the SSO menu. The collection system questionnaire must be updated at least every 12 months,,and thisis done through the "Collection System Questionnaire" link on the.SSO menu . Along with completing-thecollection system questionnaire, an enrollee musi also report all SSOs to the database. To begin a new spill report, the enrollee selects the>:"Reporting New SSO" link from the SSO menu. Then, the enrollee enters the information requested on the form. A spill report can exist at several different levels of completion: "work in • progress", "draft", "ready to certify", and "certified". A"work in progress" SSO report is a preparatory draft of the report with limited required information and is intended only for the enrollee's use.-To save a spill.report as a "work in progress", the enrollee selects the "Save Work in Progress" button on the "SSO,— General Information" screen.An" SSO report in "d• raft" status is.a working draft of the report with more required information than"work in progress" status. By submitting a report in "draft"status, the enrollee fulfills the initial, uncertified • reporting requirement'foa Category 1 spill'`The enrollee selects the "Submit Draft"button on.the`"SSO General Information".screen to submit a report as a "draft."' Once the spill report contains all the.required information, it can be submitted for certification by selecting the "Ready to Certify".button on the "SSO-General _ Information" screen. A'"ready tocertify" SSO report that is complete and accurate is certified by the enrollee through first selecting the"Modify Existing SSO" link on the SSO menu. Then, the spill report to be certified must be located by using the "SSO—Search".screen. Next,.the""Certify" button on the"SSC) —General Information" screen for the specified report is selected. Finally, the report is certified by selecting the "Certify" button on the "SSO— Certifying in a SSO`Re ort" P screen.The database will then display a confirmation of the report:certification. An enrollee has fulfilled the final, certified reporting requirement for a Category 1 or Category 2 spill by submitting a certified report in the SSO database.A spill report can be submitted directly as"ready to certify"without being'submitted as a . "work in progress" or"draft," assuming the enrollee has entered all the necessary information. - - • • When submitting a spill report, the enrollee can add supporting documentation such as pictures and reports by using the "Attachments"tab on the "SSO— General Information" screen. Additionally, the enrollee can include details about related parties (e.g., fire or police department responders) by selecting the "Spill Related Parties"tab on the "SSO—General Information" screen. A "certified" SSO report can be modified by an enrollee to correct or add information, if necessary. To do this, an enrollee begins by locating the "certified" spill report through the "SSO—Search" screen after selecting the "Modify Existing SSO" link on the SSO menu. The "Amend" button on the "SSO— General Information" screen for the designated "certified" SSO report is then selected. The spill report is returned to "Submit Draft" status and can be modified. Finally, the spill report needs to be recertified after the necessary modifications have been co'mpleted. If a sanitary sewer system doesn't have any SSOs,for an entire calendar month, a "no spill certification" must be submitted (using the "Generate No Spill Certification" link from the SSO menu) by the enrollee. A "no spill certification" must be submitted within 30 calendar days after the end of each calendar month in which no spills occur. The database will display a confirmation of the "no spill certification" when completed. The SSO database automatically sends email notifications to interested parties when spill reports are generated. When a SSO report is submitted in "draft"form ("Submit Draft" button selected)for the first time, an email notification is sent to the enrollee, responsible Regional Water Quality Control Board, and County Health Official (if known)—this is a courtesy and not required by the Sanitary Sewer Order. A report submitted as ready for certification ("Ready to Certify" button) or certified ("Certify" button) results in email notifications being sent to the enrollee, responsible Regional Water Quality Control Board, and County Health Official (if known )—this is a courtesy and not required by the Sanitary Sewer . - Order. However if a SSOreportis saved as a 'Work in progress" ("Save Work in Progress" button), no e-mail notifications are generated 6ecaue the report is preliminary and only intended to be viewed by the enrollee. As for database use by an enrollee, there are two levels of access available to staff entering the information: LROs and data submitters. LROs have full access to enter information and certify spill reports. Data submitters, on the other hand, only have authority to enter information and cannot certify SSO reports, including a "No Spill Certification". An enrollee can have multiple LROs and data submitters to enter the necessary information into the SSO database for their sanitary sewer system. 6.91 - Record Keeping Individual SSO records shall be maintained by the City for a minimum of five years from the date of the SSO.

Equipment shall include a high-velocity gun for washing and scouring manhole walls and floor. The gun shall be capable of producing flows from a fine spray to a solid stream. • Roots shall be removed in the designated sections where root intrusion is a problem. Roots shall not be a reason for reverse set-ups. Special attention should be used during the cleaning operation to ensure complete removal of roots from the joints for 33"-diameter and smaller_pipes and to ensure 90-95%removal of roots from the joints for.36"-diameter and larger pipes. Procedures may include the use of mechanical equipment such as rodding machines, bucket machines and winches using root cutters and porcupines, and equipment such as high-velocity jet • cleaners. The material resulting from the cleaning operation shall be removed at the downstream manhole of the reaches being cleaned,through the use of a filtering device. The material collected at the downstream manholes shall become the property of the Contractor. It shall be removed from the site by the Contractor in a closed container and disposed of in a legal manner. It shall not be dumped into streets,ditches,catch basins,or storm sewers. Flushing of the material from manhole reach to manhole reach is unacceptable. Acceptance of the sewer line cleaning shall be made upon the successful completion of the video inspection and shall be to the satisfaction of the Engineer.

Description of Scheduled Updates/Changes to the SSMP Directions: For each NO answer,please describe the planned revision and indicate the date the revision will be completed. Reference the SSMP element and question number with each explanation. Element 4 B: The.SSMP indicated that the Town has determined that a formal FOG Control Program is not needed because the Town is nearly 100%residential. According to County Health Department, only four food service facilities exist in the area. One of those four is Foothill College which discharges to Foothill sewer main then onto City of Los Altos' sewer system. No change or revision will be made to SSMP. Element 4 C:No FOG Control Program was set up due to Town's characteristic of a small community but.FOG Control Activities were made available for preventing or addressing FOG-related problems. The Town is prepared to evaluate the need for additional FOG control measures if it's been identified that backups are due to FOG.No change or revision will be made to SSMP until further evaluation. Element 5C: The Town does not maintain any portion of the lateral to the main. The Town is only responsible for the sewer mainline. However, should a problem on a private lateral become a public nuisance due to non-response by the lateral owner, Section 6-4.428 provides the Townauthorityto abate or correct the public nuisance. Element 6 E: The 2010 SSO annual report shows that SSO events increased from 2009 to 2010, due to heavy roots in the area and lack of resources. The Town had no contracted sewer maintenance contractor for the last five months in 2010 due to contractual and performance issues with the contractor then. A new contractor has come on board since the beginning of 2011 so the Town anticipates effective preventive maintenance activities to resume,and therefore minimize overflow events. With the new contractor's help;the Town will continue to monitor and document all SSOs and further strategize to minimize the SSOs and blockages in the future. Element 6 G: Since the Town's sewer system serves less than 10,000 people,the Town does not keep any equipment or replacement parts on hand. The Town relies on its private sewer maintenance contractor to supply adequate equipments for routine cleaning and emergency responses. No change or revision will be made to SSMP. Element 6 H: Based on the response from Element 6G,the Town does not keep any equipment or replacement parts on hand but relies on private contractor to perform cleaning maintenance and emergency response with adequate equipments. No change or revision will be made to SSMP. Element 8 B: The Sewer master plan identified that no CIP is needed until 2014 so there is no schedule for both short and long-term improvements. However,based on the past history/occurrence of sewer overflows, the Town performed a town-wide repairs and rehabilitation project in late 2010 to correct and upgrade insufficient sewer main Page 5 of 6 L:lengineeringlSANITARY SEWERISSMPISSMP Audit Reports12010 SSMP Audit Attachment l.doc • i segments and to eliminate future problems. Staff will continue to review the SSO records and TV inspections for future CIP projects. The goal is to identify improvements needed in appropriate locations throughout the Town limit and plan it accordingly with schedules for Town's CIP. Improvements include sewer line spot repairs, manhole rehabilitations and root foaming.

Description of Scheduled Updates/Changes to the SSMP Directions: For each NO answer,please describe the planned revision and indicate the date the revision will be completed. Reference the SSMP element and question number with each explanation. Element 4 B: The SSMP indicated that the Town has determined that a formal FOG Control Program is not needed because the Town is nearly 100%residential. According to County Health Department, only four food service facilities exist in the area. One of those four is Foothill College which discharges to Foothill sewer main then onto City of Los Altos' sewer system. No change or revision will be made to SSMP. Element 4 C:No FOG Control Program was set up due to Town's characteristic of a small community but FOG Control Activities were made available for preventing or addressing FOG-related problems. The Town is prepared to evaluate the need for additional FOG control measures if it's been identified that backups are due to FOG.No change or revision will be made to SSMP until further evaluation. Element 5C: The Town does not maintain any portion of the lateral to the main. The Town is only responsible for the sewer mainline. However, should a problem on a private lateral become a public nuisance due to non-response by the lateral owner, Section 6-4.428 provides the Town authority to abate or correct the public nuisance. Element 6 G: Since the Town's sewer system serves less than 10,000 people,the Town does not keep any equipment or replacement parts on hand. The Town relies on its private sewer maintenance contractor to supply adequate equipments for routine cleaning and emergency responses. No change or revision will be made to SSMP. Element 6 H: Based on the response from Element 6G,the Town does not keep any equipment or replacement parts on hand but relies on private contractor to perform cleaning maintenance and emergency response with adequate equipments. No change or revision will be made to SSMP. Element 8 B: The Sewer master plan identified that no CIP is needed until 2014 so there is no schedule for both short and long-term improvements. However, based on the past history/occurrence of sewer overflows, the Town completed a town-wide repairs and rehabilitation project in 2011 to correct and upgrade insufficient sewer main segments and to eliminate future problems. In addition, root foaming treatment is applied to all easement mainlines to target the main cause of Town's overflow events. Staff will continue to review the SSO records and TV inspections for future CIP projects. The goal is to identify improvements needed in appropriate locations throughout the Town limit and plan it accordingly with schedules for Town's CIP. Improvements include additional sewer line spot repairs, manhole rehabilitations and root foaming. Once a clear plan is established, it will be incorporated into Town's CIP for budgetary purpose. • Page 5 of 5 L:\engineering\SANITARY SEWER\SSMP\SSMP Audit Reports\201 I SSMP Audit Attachment I.doc • • Appendix J Communication Program Element Supporting Documents L) • - r- Appendix-J.:Zommunication Program Element Supporting Documents Appendix J Documents 1.
