This section fulfills the Operations and Maintenance Program requirement for the SWRCB SSMP requirements. The requirements of the G"R are: a. The City must maintain an up -to -date map of the sanitary sewer system, showing all gravity line segments, manholes, pumping facilities, pressure pipes, valves, and applicable storm water conveyance facilities;. b. The City must describe routine preventive operation and maintenance activities by staff and contractors, including a system for scheduling regular maintenance and cleaning of the sanitary sewer system with more frequent. cleaning and maintenance targeted at known problem areas The Preventative Maintenance program should have a system to document scheduled and conducted activities, such as work orders; c. The City must develop a rehabilitation and replacement plan to identify and prioritize system deficiencies and implement short -term and long term rehabilitation actions to address each deficiency. The program should include regular visual and TV inspections of manholes and sewer pipes, and a system for ranking the condition of sewer pipes and scheduling rehabilitation. Rehabilitation and replacement should focus on sewer pipes that are at risk of collapse or prone to more frequent blockages due to pipe defects. Finally, the rehabilitation and replacement plan should include a capital improvement plan that addresses proper management and protection of the infrastructure assets The plan shall include a time schedule for implementing the short and long term plans plus a schedule for developing the funds needed for the capital improvement plan; d The City must provide equipment and replacement part inventories, including identification of critical replacement parts; and e. The City must provide training on a regular basis for staff in sanitary sewer system operations, maintenance, and require contractors to be appropriately trained 4.1 Collection System Map The City has paper -based maps of its sewer system. The paper -based maps are produced from 'a master base map first drafted from 1:300 photographs in 1975. The master base map has been updated numerous times, most recently in 2000. The maps include gravity sewers (including pipe diameter), the direction of sewage flow, manholes, cleanouts, streets names, and right -of -ways. The City is currently developing an ArcGIS Geographical Information System (GIS) database of their sewer system facilities and it intends to use it to generate sewer maps beginning in December 2008. Field staff are responsible for marking up paper maps indicating discrepancies or errors identified through field verification. Field supervisors review discrepancies and errors identified and transmit requested changes to the GIS staff. The GIS Intern, under supervision of the Senior Engineering Technician, is be responsible for updating. GIS maps as facilities are added, rehabilitated, and as corrections are identified through field work. High priority changes (changes that could result in an SSO) will be incorporated into the GIS within 60 days. Updated January 2009 4.1 City of Rohnert Park Sewer System Management Plan Element 4 Operation and Maintenance Proaram Low priority changes will incorporated into the GIS on an annual basis. Sewer system map sheets for field use will be printed and distributed to the field crews as they are updated. 4.2 Preventive Maintenance 4.2.1 Preventive Maintenance Activities Gravity Sewers The City performs preventive cleaning of its gravity sewers. The City has a goal of cleaning gravity sewer lines 12 inches or smaller every three years. Problem sewer line segments are cleaned every 30, 90, 180 or 365 days. Problem sewer lines can be identified during routine cleanings, manhole inspections, and from customer calls. Appendix D contains a list of the lines on the 30 -, 90 -, 180- or 365 -day maintenance schedules. The frequency of line cleaning is subject to increase or decrease on a case by case basis, dependent on the field crew's feedback from observations during cleaning. Lines 15 inches or smaller in diameter (representing 93% of the total system length) can be cleaned by the City using its high velocity combination cleaner. Lines greater than 15 inches in diameter (representing 7% of the total system length) will be inspected by the City (using visual or CCTV inspection methods) every three years and they will be cleaned by contractors when needed. Cleaning of gravity sewers is tracked in the field on paper log sheets and then inputted monthly into an Access Database. Manholes Currently, minor repairs on manholes are performed at the time of detailed manhole inspection: Major repair issues are noted and added to a list to be fixed at a future date. Manhole inspection records are tracked in the field on paper log sheets and then inputted monthly into an Access Database. Beginning in Calendar Year 2009, the City cleaning crews will begin documenting the existence of manhole maintenance defects (e.g. roots, grease, debris) found during sewer cleaning activities and will identify whether an additional condition assessment inspection needs to be performed (e.g. structural defects). Through this process, every manhole in the system will be inspected by either a cleaning crew, manhole inspection crew, or both in a three -year cycle in conjunction with the system -wide sewer cleaning program. The manhole condition assessment inspections will focus on recording the severity of manhole issues in a code -based format. Manhole inspection records will be compiled and all repairs will be prioritized based on severity. Force Mains The City has two major force mains that connect the City's collection system to the Santa Rosa Subregional System. Air relief valves are inspected and maintained annually. Force mains are cleaned when conditions warrant. The City's newer force main conveying the City's flows to the Santa Rosa Subregional System is equipped with a pig launcher to allow for cleaning. Cleaning. and inspection of the City's older force main conveying the City's flows to the Santa Rosa Subregional Treatment Plant is conducted every two to four years, as conditions warrant. Force main. maintenance is currently recorded on paper log sheets that are stored at the pump stations. Pump Stations The City performs daily inspections of Pump Station No. 1 and Pump Station No. 2 (pump stations at the two major force mains that connect the City's system to the Santa Rosa Subregional System). The City performs twice weekly inspection of Pump Station No. 3. Between inspections, the City monitors pump station performance using a Supervisory Control and Data Acquisition (SCADA) system that relays information to a computer at the Public Works Department and that sends notification of pump station alarms to the Public Safety Dispatch Center (see Element 2). Pump station maintenance is completed as needed based on the inspections. Pump station maintenance activities include preventygand corrective Updated January 2009 4.2 City of Rohnert Park Sewer System Management Plan Element 4 Operation and Maintenance Program maintenance activities. Pump station maintenance is currently recorded on paper log sheets that are stored at the pump stations. Non - Routine Maintenance Non - routine maintenance activities include investigation and response to any complaints regarding an overflowing manhole, missing, loose, or noisy manhole covers, private residential plumbing issues, pump station malfunctions, sewer odor complaints, etc. Non - routine maintenance activities are recorded in the service request system or in hard copy file. 4.2.2 Preventive Maintenance Scheduling and Tracking The City maintains an Access database which contains information about each pipe segment and manhole in the collection system. Pipe segment information includes pipe identification number, diameter, length, material, basin number, street name and block number (e.g. 5400 block of Holly St.). Manhole information includes manhole number, rim and invert elevations, X -Y coordinates, and nearest street address (e.g. 5420 Holly St.). Cleaning frequency and manhole inspection information are recorded in the Access database as discussed above. The Access database also contains links to As -Built drawings for each pipe line segment and manhole. The City uses the Access database to query lines needing cleaning by basin number. The City is evaluating computerized options for planning, tracking and scheduling maintenance activities. The City will complete its evaluation in the near future. The computer -based maintenance management system will be used for gravity sewer, manhole, pump station, and force main maintenance activities. 4.3 Rehabilitation and Replacement Plan 4.3.1 Repair and Replacement Program Sewer facility replacement or repairs noted during preventive maintenance and condition assessments are completed in one of two ways. The City staff has the capacity to perform some of the sewer facility repairs and replacements. Repair or replacement projects that cannot be completed by City staff are carried out using contractors. Repair or replacement projects that constitute major capital projects are scheduled into the City's Capital Improvement Plan, as discussed below. 4.3.2 Condition Assessment Closed Circuit Television Inspection Proaram The City has performed periodic Closed Circuit Television (CCTV) inspection over the past few years as part of Infiltration and Inflow (I/I) investigations (see Section 8.1.3. in Element 8). In 2008, the City inspected approximately 40,000 linear feet of pipe located within 200 feet of creeks or streams. The City plans to implement a five -year CCTV inspection of all gravity sewers installed before 1974 (approximately 31 miles or 40 percent of the total system). Lines installed before 1974 were selected for the CCTV inspection program because, assuming the program ends in 2013; these lines will have been in use for 40 or more years. The long period of use makes these gravity sewers more likely to have rehabilitation or replacement needs than more recently installed pipes. At the end of the five year CCTV Inspection program, the City will develop a condition assessment program for the remaining gravity sewer assets and for pre -1974 gravity sewers that were scheduled for re- inspection. Lateral Inspection and Replacement Program The City enacted a lateral compliance ordinance in 2007 which requires testing and/or inspection of private sewer laterals under certain conditions, including: Updated January 2009 4-3 City of Rohnert Park Sewer System Management Plan Element 4 Operation and Maintenance Program Application for a new connection to the sewer collection program, or • Application for a change of use on the premises served from residential to commercial, or from non- restaurant commercial to restaurant commercial, or • Application for a change of use on the premises served from any other land use to common interest development, or Upon determination of the City Engineer that the cleaning and testing is required to abate a nuisance or for the protection of the public health, safety and welfare. 4.3.3 Capital Improvement Plan The City maintains a Five -Year Capital Improvement Program (CIP). The CIP includes the list of funding sources and schedule of expenditures for each project. The budget for the CIP was adopted in July 2007. The City's CIP includes manhole repairs to reduce I/I, and sewer repair and replacement (including condition assessment for pre - design). The City will incorporate a separate project for condition assessment into the CIP in the future. 4.4 Equipment The list of major equipment that the City uses in the operation and maintenance of its collection system and pump stations is included in Appendix E. The City maintains contracts with local suppliers and contractors to obtain parts and labor for emergency repairs. A list of local suppliers and contractors is included in Appendix F. 4.5 Training Currently, employee O &M program training includes information training through in -house classes, on- the-job training, conferences, seminars, etc. The City will be implementing a formal training program by December 2008. Training will include Overflow Emergency Response Training. The City will continue to utilize resources of professional organizations (e.g. CWEA) for other types of training and encourages employees to participate in conferences and seminars. The City tracks training activities in an electronic form. The electronic form includes the dates of attendance, .contact hours earned, and indication if a certificate of training is kept on file. Through contracts and specifications, the City will also require that contractors performing maintenance and CCTV inspection work on the City's collection system facilities are properly trained. Contractors are responsible for understanding the City's sewer facilities and the potential impacts the work the contractor is performing can have in creating SSOs.

At a minimum, this plan must include the following: (a) Proper notification procedures so that the primary responders and regulatory agencies are informed of all SSOs in a timely manner; (b) A program to ensure appropriate response to all overflows; (c) Procedures to ensure prompt notification to appropriate regulatory agencies and other potentially affected entities (e.g. health agencies, regional water boards, water suppliers, etc.) of all SSOs that potentially affect public health or reach the waters of the State in accordance with the Monitoring and Reporting Program (MRP). All SSOs shall be reported in accordance with this MRP, the California Water Code, other State Law, and other applicable Regional Water Board Waste Discharge Requirements (WDR) or National Pollutant Discharge Elimination System (NPDES) permit requirements. The Sewer System Management Plan should identify the officials who will receive immediate notification; (d) Procedures to ensure that appropriate staff and contractor personnel are aware of and follow the Emergency Response Plan and are appropriately trained; (e) Procedures to address emergency operations, such as traffic and crowd control and other necessary response activities; and (f) A program to ensure that all reasonable steps are taken to contain untreated wastewater and prevent discharge of untreated wastewater to Waters of the United States and minimize or correct any adverse impact on the environment resulting from the SSOs, including such accelerated or additional monitoring as may be necessary to determine the nature and impact of the discharge. 1.3 Goals The City's goals with respect to responding to SSOs are: • Respond quickly to' minimize the volume of the SSO; • Eliminate the cause of the SSO; • Contain the spilled wastewater to the extent feasible; • Minimize public contact with the spilled wastewater; • Mitigate the impact of the SSO; and • Meet the regulatory reporting requirements. April 2008 1 -1 City of Rohnert Park Overflow Emergency Response Plan Section 1 Introduction 1.4 Definitions • Building lateral - the portion of the sewer that connects a specific building or property to the street lateral at the property line. • Category 1 SSO — all discharges of sewage resulting from a problem in the City's sanitary sewer system that: • Equal or exceed 1000 gallons, or • Result in a discharge to a drainage channel and/or surface water; or • Discharge to a storm. drainpipe and was not fully captured and returned to the sanitary sewer system. Category 2 SSO — all other discharges of sewage resulting from a problem in the City's sanitary sewer system that are not Category 1 SSOs. • First responder — the Public Works Utilities Services Crew that provides the City's initial response to an SSO event or other sewer system event. • OERP — Overflow Emergency Response Plan. • OES — OES refers to the Governor's Office of Emergency Services. • Private Lateral Spill — sewage discharges that are caused by blockages or other problems within a private sewer lateral. • Property damage overflow —a sewer overflow or backup that damages private property. • RWQCB — North Coast Regional Water Quality Control Board. • Sanitary sewer overflow (SSO) — the discharge of untreated or partially treated sewage at any point upstream of the treatment plant. • Sensitive area — areas where an SSO could result in a fish kill or pose an imminent or substantial danger to human health. • Sewer system — the sanitary sewer facilities owned and operated by the City. • Sewer lateral — the piping that conveys sewage from the building to the City's sewer system. The property owner is responsible for maintenance of the sewer lateral (building and street laterals). • Street lateral — the portion of the city, sewer that connects the sewer main to the building lateral at the property line. I • SWRCB — the California State Water Resources Control Board. • Water body — any stream, creek, river, pond, impoundment, lagoon, or wetland. • Water of the State — any water, surface or underground, including saline waters, within the boundaries of California. In case of a sewage spill, storm drains are considered to be waters of the State unless the sewage is completely contained and returned to the sewer system. April 2008 1 -2 City of Rohnert Park Overflow Emergency Response Plan Section 2 SSO Detection Section 2 SSO Detection The processes that are employed to notify the City. of the occurrence of an SSO include: observation by the public, receipt of an alarm, or observation by City staff during the normal course of their work. 2.1 Public Observation Public observation is a common way that the City is notified of blockages and spills. Contact information for reporting sewer spills and backups are in the phone book and on the City's website: www.rpcity.org. The City's Public Works telephone number is (707) 588 -3300 during working hours. After hours, calls to the Public Works telephone number are automatically redirected to an answering service. Normal Work Hours The City's regular working hours are 7:30am to 5:30pm, Monday through Thursday, and every other Friday, with the exception of holidays and off - Fridays. When a report of a sewer spill or backup is made, Public Works Dispatch receives the call, takes the information from the caller, and communicates it to Supervising Maintenance Worker who responds to the site and/or dispatches a field crew. After Hours After hours, callers are automatically transferred to an answering service. The answering service receives the call, takes the information from the caller, and communicates it to the Maintenance On -call Personnel. The Maintenance On -call Personnel responds to the site and, if necessary, calls additional Maintenance Workers for assistance. 2.2 Receipt of Alarm The City's three pump stations have alarm systems with autodialers that notify the Public Safety Dispatch Center of an alarm condition via telephone. During working hours, Public Safety Dispatcher contacts the Public Works Dispatch to respond to the alarm. After hours, the Public Safety Dispatcher contacts the On -Call Maintenance Personnel directly. The Public Safety Dispatcher number is (707) 584 -2600. 2.3 City Staff Observation City staff conducts periodic inspections of its sewer system facilities as part of their routine activities. Any problems noted with the sewer system facilities are reported to appropriate City staff who respond to emergency situations. Work orders are issued to correct non - emergency conditions (non- SSOs). April 2008 24 City of Rohnert Park Overflow Emergency Response Plan Section 3 SSO Response Procedures Section 3 SSO Response Procedures Sewer service calls and pump station alarms are considered high priority events that demand a prompt response to the location of the problem. The response procedure flow chart is shown on Figure 3 -1. Figure 3 -1: Response Procedure Flow Chart After hours, calls are directed to During working hours, SSO Observer Answering Service calls go to Public Works Dispatch Pump Station City Hall Answering Service Alarms After hours, _ Answering Public Safety Public Works Service Dispatch Center Dispatch dispatches crew During working Maintenance hours � On -Call After hours, Public Safety Personnel contacts On -Call Supervising Personnel directly Maintenance Worker Supervising Maintenance Worker Crew Responds Public Works Public Works Supervisor Manager SSO Notification and Reporting to Appropriate Agencies April 2008 34 City of Rohnert Park Overflow Emergency Response Plan Section 3 SSO Response Procedures 3.1 First Responder Priorities The first responder's priorities are: • To follow safe work practices. • To respond promptly with the appropriate equipment. • To contain the spill wherever feasible. • To restore the flow as soon as practicable. • To minimize public access to and /or contact with the spilled sewage. • To promptly notify the Supervising Maintenance Worker or the Public Works Supervisor in event of any SSO. • To return the spilled sewage to the sewer system. • To restore the area to its original condition (or as close as possible). 3.2 Safety during Response The first responder is responsible for following safety procedures on all jobs. Special safety precautions must be observed when performing sewer work. There may be times when City personnel responding to a sewer system event are not familiar with potential safety hazards peculiar to sewer work. In such cases it is appropriate to take the time to discuss safety issues, consider the order of work, and check safety equipment before starting the job. 3.3 Initial Response The first responder must respond to the reported location or pump station site and visually check for potential sewer stoppages or overflows. All sewer system calls require a response to the reported location of the event. The first responder should: • Note arrival time at spill site. • Verify the existence of an SSO or sewer system backup. • Identify and assess the affected area and extent of SSO. • Contact caller if time permits. • Notify the Supervising Maintenance Worker: o If the spill appears to be a large SSO, any SSO in a sensitive area, or if there is doubt regarding the extent, impact, or how to proceed. o If the SSO is in a public roadway and help with traffic control is needed to protect workers and the public. o If additional help is needed, the Supervising Maintenance Worker or Public Works Supervisor will contact other employees, contractors, and/or equipment suppliers. • If the SSO is large or in a sensitive area, document conditions with photographs. If the spill is occurring inside a private residence or business: • Immediately contact Redwood Empire Municipal Insurance Fund at (707) 938 -2388 and Cal North Adjusters at (707) 539 -7785. • Cal North Adjusters Representatives will come to the site immediately and will make all arrangements for clean up and repairs. • First Responder will document conditions with photographs. April 2008 3 -2 City of Rohnert Park Overflow Emergency Response Plan Section 3 SSO Response Procedures • Decide whether to proceed with actions to restore the flow or to initiate containment measures. The guidance for this decision is: • Small SSO — proceed with restoring flow (e.g. clear blockage, restore pump station operation, temporary bypass pumping around issue spot). • Moderate or large SSO where containment is anticipated to be simple — proceed with the containment measures. • Moderate or large SSO where, containment is anticipated to be difficult — proceed with restoring flow (e.g. clear blockage, restore pump station operation, temporary bypass pumping around issue spot); however, call for additional assistance after. 15 minutes without restoration of flow and implement containment measures. 3.4 Initial Spill Containment Measures The first responder should attempt to contain the spilled sewage using the following steps: • Determine the immediate destination of the overflowing sewage. • Plug storm drains using air plugs, sandbags, and/or plastic mats to contain the spill, whenever appropriate. If overflowing sewage has entered the storm drainage system during dry weather, attempt to contain the spilled sewage by plugging downstream storm drainage facilities. • Contain/direct the .spilled sewage using dike /dam or sandbags. • Pump around the blockage /pipe failure /pump station, if not already. initiated. April 2008 3 -3 City of Rohnert Park Overflow Emergency Response Plan Section 4 Recovery and Clean Up Section 4 Recovery and Clean Up The recovery and clean up phase begins when the flow has been restored and the overflow of sewage has been stopped. The SSO recovery and clean up procedures are: Estimate the Volume of Spilled Sewage Use the methods outlined in Appendix D - Methods for Estimating Spill Volume to estimate the volume of the spilled sewage. Wherever possible, document the estimate using photos of the SSO site before the recovery operation. Recovery of Spilled Sewage Vacuum up or pump the spilled sewage and discharge it back into the sanitary sewer system. Clean Up and Disinfection Clean up and disinfection procedures should be implemented to reduce the potential for human health issues and adverse environmental impacts that are associated with an SSO event. The procedures described are for dry weather conditions and should be modified as required for wet weather conditions. Where cleanup is beyond the capabilities of City staff, a clean up contractor will be used. • Private Property • If the spill has occurred on private property but outside of a structure (e.g. residence, building, etc.), offer assistance with clean up and advise resident or property owner of claim procedures. • If the spill has occurred on private property inside a structure (e.g. home, building, etc.), Cal North Adjusters Representatives will make all arrangements for clean up and repairs. • Hard Surface Areas • Collect all signs of sewage solids and sewage - related material either by hand or with the use of rakes and brooms. • Wash down the affected area with clean water. Take reasonable steps to contain and vacuum up the wash water. • Disinfect all areas that were contaminated from the overflow using the disinfectant solution. Apply minimal amounts of the disinfectant solution using a hand sprayer. Document the volume and application method of disinfectant that was employed. • Allow area to dry. Repeat the process if additional cleaning is required. • Landscaped and Unimproved Natural Vegetation • Collect all signs of sewage solids and sewage- related material either by hand or with the use of rakes and brooms. • Wash down the affected area with clean water until the water runs clear. The flushing volume should be approximately three times the estimated "volume of the spill. • Either contain or vacuum up the wash water so that none is released. • Allow the area to dry. - Repeat the process if additional cleaning is required. • Natural Waterways • The Department of Fish and Game should be notified in the event an SSO impacts any surface water or riparian habitat. Fish and Game will provide the professional guidance needed to effectively clean up spills that occur in these sensitive environments. • Performing water quality sampling, if required as discussed in Section 6 Water Quality Sampling and Testing. April 2008 44 City of Rohnert Park Overflow Emergency Response Plan Section 4 Recovery and Clean Up o Clean up should proceed quickly in order to "Alinimize negative impact. Sewage causes depletion of dissolved oxygen which will kill. aquatic life. o Any water that is used in the cleanup should be de- chlorinated prior to use (chlorine compounds are toxic to aquatic life). • Wet Weather Modifications o Omit flushing and sampling during heavy storm events with heavy runoff where flushing is not required and sampling would not provide meaningful results. • Overflows at Night o In the event that an overflow occurs at night, the location should also be inspected the following day. The operator should look for any signs of sewage solids and sewage - related material that may warrant additional clean up activities. April 2008 4 -2 City of Rohnert Park Overflow Emergency Response Plan Section 5 Public Notification Section 5 Public Notification Post signs and place barricades to keep vehicles and pedestrians away from contact with spilled sewage. Do not remove the signs until directed by the Public Works Supervisor or Supervising Maintenance Worker. A sample warning sign is included as Appendix F - Warning Sign. Creeks and streams that have been contaminated as a result of an SSO should be posted at visible access locations until the risk of contamination has subsided to acceptable background levels. The warning signs should be checked every day to ensure that they are still in place. Major spills may warrant broader public notice. The City Manager will authorize contact with local media when significant areas may have been contaminated by sewage. April 2008 5 -1 City of Rohnert Park Overflow Emergency Response Plan Section 6 Water Quality Sampling and Testing. Section 6 Water Quality Sampling and Testing Water quality sampling and testing are required to determine the extent and impact of the SSO whenever 500 gallons or more of spilled sewage enters surface water. The water quality sampling procedures are: The first responder should notify the Supervising Maintenance Worker that water quality samples need to be collected. The Supervising Maintenance Worker will contact the City of Santa Rosa to collect samples. Samples should be collected as soon as possible after the discovery of the SSO event. • The water quality samples should be collected from upstream of the spill, from the spill area, and downstream of the spill in flowing water (e.g. creeks). The water quality samples should be collected near the point of entry of the spilled sewage and every 100 feet along the shore on impoundments (e.g. ponds). • The City of Santa Rosa Laboratory will analyze the results to determine the nature and extent of the discharge. Additional samples will be taken to determine when posting of warning signs can be discontinued. The basic analyses should include total coliform, fecal coliform, biochemical oxygen demand (BOD), dissolved oxygen, and ammonia nitrogen. I April 2008 6 -1 City of Rohnert Park Overflow Emergency Response Plan Section 7 SSO Investigation and Documentation Section 7 SSO Investigation and Documentation All SSOs should be thoroughly investigated and documented for use in managing the sewer. system and meeting established reporting requirements. The procedures for investigating and documenting SSOs are: Failure Analysis Investigation The objective of the failure analysis investigation is to determine the "root cause" of the SSO and to identify corrective action(s) needed that will reduce or eliminate future potential for the SSO to recur. The investigation should include reviewing relevant data to determine appropriate corrective action(s). The investigation should include: • Reviewing and completing the Collection System Service Call/Overflow Field Report, • Reviewing past maintenance records, • Reviewing available photographs, • Conducting a CCTV inspection to determine the condition of the line segment immediately following the SSO and reviewing the video and logs, and • Interviewing staff who responded to the spill. The product of the failure analysis investigation should be the determination of the root cause and the identification of the corrective actions. The completed Collection System Failure Analysis Form Appendix C - Failure Analysis Form should be included in the SSO file. SSO Documentation The first responder will complete the Collection System Service Call /Overflow Field Report Form (see Appendix A - Collection System Service Call/Overflow Field Report Form). First Responder /Supervising Maintenance Worker (working hours) or Public Works Supervisor (after hours) will complete the Sewer Overflow Building History Form (see Appendix B -Sewer Overflow Building History Form) if an SSO has occurred in a residence or building. The Supervising Maintenance Worker will prepare a file for each individual SSO. The file should include the following information: All SSOs • Initial service call information. • Collection System Service Call/Overflow Field Report form. • Failure analysis investigation results. • SWRCB California Integrated Water Quality System (CIWQS) Report(s) (see Section 8 SSO Reporting) Large SSOs and /or SSOs to sensitive areas • Volume estimate. • Appropriate maps showing the spill location. • Photographs of spill location. • Water quality sampling and test results. Note that individual SSO records shall be maintained for a minimum of .five years from the date of the SSO. April 2008 74 City of Rohnert Park Overflow Emergency Response Plan Section 7 SSO Investigation and Documentation Post SSO Event Debriefing Every SSO event is an opportunity to thoroughly evaluate the response and reporting procedures. Each overflow event is unique, with its own elements and challenges including volume, cause, location, terrain, and other parameters. As soon as possible after major SSO events, all of the participants, from the person who received the call to the last person to leave the site, should meet to review the procedures used and to discuss what worked and where improvements could be made in responding to and mitigating future SSO events. The results of the debriefing should be recorded and tracked to ensure the action items are completed. April 2008 7 -2 City of Rohnert Park Overflow Emergency Response Plan Section 8 SSO Reporting Section 8 SSO Reporting The internal and external reporting process for SSO events that are intended to meet the SWRCB requirements are summarized below. Category 1 and 2 SSOs are defined as: , • Category 1 SSO - Category 1 SSO refers to all discharges of sewage resulting from a.problem in the City's sanitary sewer system that: • Equal or exceed 1000 gallons, or • Result in a discharge to a drainage channel and/or surface water; or • Discharge to a storm drainpipe that was not fully captured and returned to the sanitary sewer system. • Category 2 SSO — Category 2 SSO refers to all other discharges of sewage resulting from a problem in the City's sanitary sewer system that are not Category 1 SSOs. 8.1 Internal SSO Reporting Procedures Category 1 SSOs The first responder will immediately notify the Supervising Maintenance Worker (working hours) or the Public Works Supervisor (after hours) who in turn will notify the Public Works Manager. The Supervising Maintenance Worker (working hours) or the Public Works Supervisor (after hours) will meet with field crew(s) at the site of the SSO event to assess the situation and to document the conditions with photos. . The first responder will fill out the Collection System Service Call/Overflow Field Report and turn it in as soon as possible to Supervising Maintenance Worker (working hours) or the Public Works Supervisor (after hours). In the event of a very large overflow or an overflow in a sensitive area, the Public Works Manager will notify the City Manager. The City Manager may notify the City Council. Category 2 SSOs The first responder will fill out the Collection System Service Call /Overflow Field Report and turn it in to Supervising Maintenance Worker by the start of the next working day. 8.2 External SSO Reporting Requirements Category 1 SSOs — Resulting in a Discharge to a Drainage Channel and /or Surface Water The Supervising Maintenance Worker or Public Works Supervisor will notify the Office of Emergency Services (OES) (and obtain a Spill Control Number), the RWQCB, and the County Health Agency as soon as possible without interfering with the response activities but no later than 2 hours after spill event is first reported to the City. After contacting the OES and the County Health Agency, but within 24 hours of spill event being reporting to the City, the Supervising Maintenance Worker or Public Works Supervisor shall submit to the RWQCB certification that OES and the County Health Agency have been notified of the discharge. The Supervising Maintenance. Worker will prepare an initial electronic report using the California Integrated Water Quality System (CIWQS) within three working days of completion of the response and mitigation activities. The Public Works Supervisor or his/her designee will certify the report. The report will include the information required to meet the SWRCB requirements. The Supervising Maintenance Worker will prepare a final electronic report using CIWQS within fifteen calendar days of completion of the response and mitigation activities. The Public Works Supervisor or April 2008 8 -1 City of Rohnert Park Overflow Emergencv Response Plan . Section 8 SSO Renortin his/her designee will certify the report. The final report will include the information required to meet the SWRCB requirements. Category 1 SSOs — Not Resulting in a Discharge to a Drainage Channel and /or Surface Water The Public Works Supervisor will notify the OES (and obtain a Spill Control Number), the RWQCB, and the County Health Agency as soon as possible without interfering with the response activities but no later than 24 hours after notification of the spill event. The Supervising Maintenance Worker will prepare an initial electronic report using CIWQS within three working days of completion of the response and mitigation activities. The Public Works Supervisor or his/her designee will certify the report. The report will include the information required to meet the SWRCB requirements.

This appendix documents the three methods that are most often employed. The person preparing the estimate should use the method most appropriate to the sewer overflow in question and use the best information available. Method 1 Eyeball Estimate The volume of small spills can be estimated using an "eyeball estimate ". To use this method imagine the amount of water that would spill from a bucket or a barrel. A bucket contains 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. Step 1 Sketch the shape of the contained sewage (see Figure 1). 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 3.14) / 4 Triangle: Area = base (feet) x height (feet) x 0.5 Step 6 Multiply the area (square feet) times the depth (in feet) to obtain the volume in cubic feet. Step 7 Multiply the volume in cubic feet by 7.5 to convert it to gallons Figure 1: Common Shapes and Dimensions 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, the separate estimates are made of the duration of the spill and the flowrate. The 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. 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, included as Appendix F, 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. • Foowmeter: 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 = 3.3 gallons per minute Spill Volume: Once duration and 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 example: Spill start time = 11:00 Spill end time = 14:00 Spill duration = 3 hours 3.3 gallons per minute X 3 hours X 60 minutes per hour = 594 gallons Appendix E - Manhole Overflow Rate Guide v T vai � •a' AA C IM g E C cr.

This section fulfills the FOG Control Program requirement for the SWRCB SSMP requirements. The requirements of the GWDR are: 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 rem oval 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. 7.1 FOG Source Control Program The City and City of Santa Rosa (Santa Rosa) have signed an Inspection Services Agreement (City Council Resolution No. 91 -146, authorized in 199 1) that Santa. Rosa will-provide Commercial/Industrial Inspection Services including notification to users of non - compliance, issuing and renewing discharge permits, interviews, sampling and monitoring, reporting, record keeping, and related services. A copy of the Agreement is included as Appendix H. Under this agreement, the City of Santa Rosa provides the FOG Source Control Program in the City's service area. The program is focused on food service establishments and includes plan review and specification of grease removal equipment (based on Uniform Plumbing Code sizing criteria), permitting, compliance inspections, and enforcement. Santa Rosa requires food service establishments to employ Best Management Practices. Updated January 2009 7 -1 City of Rohnert Park Sewer System Management Plan Element 7 Fats, Oils and Grease Control Program 7.2 Public Education Outreach Program The Russian River Watershed Association (RRWA), of which the City is a member, provides a regional public education program on the proper handling of household grease. The RRWA provides program support including door hangers and stickers for turkey flyers to educate the public on the proper disposal of FOG. The RRWA publishes a monthly environmental column in many local area newspapers and rotates in articles about proper grease and oil disposal, especially during the winter holiday season. The FOG Program section of the RRWA website provides the public with advice on how to take grease "from the Pan to the Can" and includes a list of locations where large and small quantities of cooking oil can be deposited for proper disposal and bio- diesel processing.. Information about the RRWA FOG Program is available to the public online (www.rrwatershed.org/FOG). 7.3 Disposal of FOG Local grease haulers can dispose of grease at a variety of regional locations including wastewater treatment plants (e.g. East Bay Municipal Utility District Treatment Facility in Oakland) and rendering facilities (e.g. Ukiah, South San Francisco, Sacramento, Chico). East Bay Municipal Utility District ( EBMUD) maintains a list of approved regional grease haulers, some of which service the City's service area. The approved grease haulers have a good track record with EBMUD for proper grease disposal. The EBMUD list of approved grease haulers can be found on their website (www.ebmud.com/wastewater / industrial_ &_commercial _permits_ &_ fees /pollution _prevention _program/ FOG /default.htm). As discussed in Section 7.2 Public Education Outreach Program, the RRWA maintains a list of locations where residents can take grease for disposal. The RRWA list can be found on their website (www.rrwatershed.org/FOG). 7.4 Legal Authority to Prohibit Discharges The City has the legal authority to prohibit discharges of FOG to the wastewater collection system. See Element 3 Legal Authority for additional discussion of the City's legal authority relating to FOG control. 7.6 Requirements to Install Grease Removal Devices Section 13.48.070 of the City's Municipal Code requires the installation of a grease interceptor when necessary, as decided by the City Engineer. Santa Rosa, who issues the Non - Residential Food Service Discharge Permits in the City's service area as part of the Source Control program, has an Interceptor Policy that specifies the requirements for interceptor sizing. A copy of the Interceptor Policy is included as Appendix I. The Santa Rosa Discharge Permit specifies the maintenance, record keeping, and reporting requirements the permit holder has to meet relative to their grease removal device. 7.6 Authority to Inspect and Regulate Grease Producing Facilities The Inspection Services Agreement and the City's Sanitary Code provide Santa Rosa's inspectors with the right of entry onto properties in Rohnert Park. The Inspection Services Agreement establishes that Santa Rosa shall refer dischargers who are in violation of the Rohnert Park Sanitary Code to the Sonoma County District Attorney for prosecution. Prior to prosecution, Santa Rosa and the City work collectively to bring the discharger into compliance. Santa Rosa, working with City staff, will 1) provide a verbal warning of violation, 2) send a Notice of Violation to the discharger, 3) hold an administrative hearing with the Discharger, and 4) send an Order to Cease and Desist Sewer Discharge contingent upon installation of a grease interceptor. If a Discharger does not comply after all four of these actions have been tried, prosecution can be sought against the Discharger. Updated January 2009 7.2 City of Rohnert Park Sewer System Management Plan Element 7 Fats, Oils and Grease Control Program 7.7 Identification of Grease Problem Areas and Sewer Cleaning The City currently keeps a record of sewer lines with grease- related problems in an MS Access database. Grease lines are identified during routine cleanings, from customer calls, or during manhole inspections. When a line is identified as .having a grease - related problem, it is put on a monthly, qu4rterly, or annual sewer cleaning cycle as appropriate to manage grease buildup. As the City implements the CCTV Inspection Program (see Element 4), grease lines will be noted during CCTV inspections and added to an increased cleaning frequency list (monthly, quarterly, annually) as appropriate.

This section fulfills the System Evaluation and Capacity Assurance Plan requirement for the SWRCB SSMP requirements. The requirements of the GWOR are: The City must evaluate those portions of the sanitary sewer system that are experiencing or contributing to an SSO discharge caused by hydraulic deficiency. The evaluation must provide estimates of peak flows (including flows from SSOs that escape from the system) associated with conditions similar to those causing overflow events, estimates of the capacity of key system components, hydraulic deficiencies (including components of the system with limiting capacity) and the major sources that contribute to the peak flows associated with overflow events. Where design criteria do not exist or are deficient, the City must establish appropriate design criteria The City must 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, III reduction programs, increases and redundancy in pumping capacity, and storage facilities. The CIP shall include an implementation schedule and shall identify sources of funding. The City shall develop a schedule of completion dates for all portions of the CIP. This schedule shall be reviewed and updated at least every two years. 8.1 Capacity Evaluation Over the past 2.5 years, the City has not experienced SSOs caused by inadequate hydraulic capacity. However, since 1999, the City has had a program to quantify .flows in the system through flow monitoring, identify sources of infiltration/inflow (I/I) that contribute to peak flows, and identify potential capacity deficiencies based on hydraulic modeling. 8.1.1 Flow Monitoring and Flow Quantification Total flows in the system are measured on the discharge end of the pump station to the wastewater treatment plant. Flows are also measured at the connection from Sonoma State University. Wet weather flow monitoring in the collection system was previously conducted (during years 1999 through 2004) to quantify flows from 28 sewer drainage basins. The flow monitoring data was analyzed to estimate peak I/I and peak wet weather flow (PWWF) for a specified design storm. The design storm is a synthetic 5- year, 6 -hour duration rainfall event as defined in NOAA Western U.S. Precipitation Frequency Maps Atlas 2, 1973. 8.1.2 Hydraulic Analysis The City has developed a hydraulic model which includes all pipes in the existing sewer system. The model was developed and is run by a consultant to the City. Flows in the model are based on the results of flow monitoring projected to 5 -year design storm, as described above. The model has been used to quantify flows in each pipe and identify potential capacity deficiencies based on hydraulic evaluation criteria. The criteria specify the maximum allowable flow depth to diameter ratio (d/D) based on pipe size, ranging from 0.7 for 6 -inch pipe to 0.9 for 30 -inch pipe. Updated January 2009 8 -1 City of Rohnert Park Sewer System Management Plan Element 8 System Evaluation and Capacity Assurance Plan The City has also incorporated flows from future development areas into the model, specifically for six Specific Plan Areas (SPAS) as well as infill. For evaluating flows from future development, the City has established flow criteria for determining base wastewater flow, peak dry weather flow, 1/I, and peak wet weather flow. The model has been used to identify and optimize tie -in points of new development and existing sewers to a major new trunk sewer, the Eastside Trunk Sewer (see discussion in Section 8.2). The model will be updated in the future whenever significant changes to planned development are proposed. The City will also monitor total flows in the system as measured at the downstream pump station to identify if flows are consistent with planned flows as predicted by the modeling. 8.1.3 Ill Analysis The City has an ongoing I/I reduction program as part of an overall regional effort for the Santa Rosa Subregional Wastewater Reclamation System. In addition to flow monitoring, flow analysis, and modeling, described above, the City has conducted I/I source detection field work, including manhole inspections and closed - circuit television (CCTV) inspection, to identify specific sources of UI in sewer basins identified as having the highest I/I contributions. This information has been used to estimate the amount of I/I that could be reduced through I/I correction projects. Some projects have been implemented, as described below. 8.2 Capacity Assurance Plan In 2005, the City constructed a parallel force main to the Santa Rosa Subregional Water Reclamation Plant to provide sufficient capacity to convey existing and future peak wet weather flows and to provide redundancy under dry weather flows. The City also constructed a new pump station and'dual force mains to provide service to the new sewer system in the Canon Manor area. The City's Five -Year Capital Improvement Program (CIP) currently includes two projects related to capacity: • Eastside Sewer Project (CIP #WW -07). The Eastside Sewer is a new 18- through 42 -inch diameter pipeline that will provide capacity for development of new SPAs and capacity relief for the existing sewer system. Phase I of the project is scheduled to be completed in 2008. Phase II of the project is currently unscheduled, but likely to be commenced within five years. • I/I Reduction Program (CIP #WW -01). This program, currently budgeted at $100,000 per year, is targeted at reducing I/I as part of overall regional effort to reduce flows to the wastewater treatment plant. Previous phases of the program have included flow monitoring and source detection, as described above. A manhole rehabilitation pilot project was conducted in 2006, and another phased manhole rehabilitation project is planned for 2008 and 2009. Over the next two years, the City plans to conduct further analysis and verification of model results to determine if additional capacity projects should be added to the CIP. Such work will include ongoing monitoring of total system flows (as measured at downstream pump stations) to track flow trends and flow response during large storm events; field inspection of manholes to verify flow depth in sewers during peak flow periods; and possible additional flow monitoring in the system and/or refinements to the hydraulic model if considered warranted. Based on these additional analyses, the City will determine whether additional. capacity improvement projects need to be added to the CIP.

F / t ,� t City of Rohnert Park Sewer System Management Plan Element 10 SSMP Audits Element 10 SSMP Audits The requirements of the GWDR are: The City shall conduct periodic internal audits, appropriate to the size of the system and the number of SSOs. At a minimum, these audits must occur every two years and a report must be prepared and kept on file. This audit shall focus on evaluating the effectiveness of the SSMP and the City's compliance with the SSMP requirements, including identification of any deficiencies in the SSMP and steps to correct them. 10.1 SSMP Audits The City will audit its SSMP at least every two years. The audit will determine whether the SSMP: • Meets the current requirements of the GWDR; • Reflects the City's current practices and procedures; and • Is being followed by the City. The first audit will be completed on or before August 2, 2011, and will cover the previous two calendar years. The audit will be conducted by a team of City Public Works Department staff. The audit team may also include members from other areas of the City (e.g. Engineering), outside agencies, and /or contractors. The scope of the audit will cover each of the sections of the SSMP. The Audit Checklist, based on the current requirements of the GWDR, will be used to conduct the audit and is included in Appendix J. The results of the audit, including the identification of any deficiencies and the steps taken or planned to correct them, will be included in an Audit Report. The Audit Report will be completed and filed within 60 days of the audit. Copies of the Audit Reports will be maintained by the City for five years. 10.2 SSMP Updates The City will update its SSMP at least every five years. The first update will be completed on or before August 2, 2014. The City may determine the need to update the SSMP more frequently based on the results of the bi- annual audit and the performance of its sanitary sewer system using information from the Monitoring and Measurement Program (See Element 9). If it is determined that an update is warranted, the process to complete the update will be identified. Consistent with the SSMP re- certification requirements, the City Staff will seek approval from the City Council for any significant changes to the SSMP. The authority for approval of minor changes (e.g. employee names, contact information, limited procedural changes) is delegated to the Public Works Utilities Supervisor.

' The.City of Santa Rosa may require the.City.of ROHNERT PARK to provide financing for any enlargements in proportion to the share of requested additional capacity service. The City of ROHNERT PARK;. in.turn,.may require STATE to'provide financing for any enlargements in proportion to the share of-requested additional capacity service by STATE, if any. All entities shall participate in'the'annual debt servicing costs associated thereto in proportion to their capacity service expressed as a percentage of total capacity service just as if Santa Rosa were pro- viding project financing. D. Improvement of Santa Rosa Subregional Sewerage System or ROHNERT PARK Sewerage System In the event that improvement of the Santa Rosa Subregional Sewerage System or the ROHNERT PARK Sewerage System is required or mandated by an agency having jurisdiction, then STATE and ROHNERT PARK both agree to share in said improvements in proportion to their respective i capacity service.

This is an agreement (subsequently referred to as the "Agreement ") between Sonoma County and the City of Rohnert Park describing the circumstances under which the Rohnert Park will provide public wastewater collection, treatment, and disposal services�to the Canon Manor West area. The Canon Manor West area is located in the unincorporated area of Sonoma County near the intersection of Petaluma Hill Road and the East Cotati'Avenue. The Canon Manor West area is depicted on the map attached as Exhibit A to this Agreement. 2. The City of Rohnert Park is a California City. adjacent to -the Canon Manor West area. The Canon Manor West area is within Rohnert Park'. s sphere of influence, as approved by the Local Agency Formation Commission. Sonoma County is a California County within which the Canon Manor West area is currently located. 3. Because existing residential septic systems in the Canon Manor West area have caused nitrate contamination of groundwater and water wells and other problems, the Canon Manor West area properties would benefit from (a) public wastewater collection, treatment, and disposal service and (b) a reliable public potable water supply. Rohnert Park is capable of and willing to accept, treat, and dispose of. wastewater from the properties in the Canon Manor West area in accordance with the terms of this Agreement. The Penngrove Water. Company, a privately owned public utility regulated by the California Public Utilities Commission, is. capable of and willing to supply potable water to all properties in the Canon Manor West area. 4. In order to calculate the proposed parcel assessments for water and wastewater service, the type of needed improvements to be paid from assessment district bond ,proceeds must first be determined, and their cost estimated, and the appropriate charge established for each parcel specially benefited. The Canon Manor West property owners will subsequently decide in 2001 whether or not to approve an assessment district that will pay for public wastewater collection and treatment service and potable water service and related costs. Page 1 of 12 October 11, 2001 5. In this Agreement Sonoma County and Rohnert Park desire to set forth the public wastewater services which Rohnert Park agrees to supply to existing lots in the Canon Manor .West area. Sonoma County will then be able to allocate the estimated cost of those improvements to each parcel in proportion to the special benefit conferred on that parcel. Pursuant to state law, the owners of the parcels for which an assessment is proposed will receive a ballot indicating their support or opposition to the proposed assessment. Subsequently the assessment district may or may not be formed, depending upon the outcome of the legally required protest ballot procedure and other state law requirements. In addition, the owners of the parcels for which an assessment is proposed will vote whether. or not to approve an annual wastewater and private road maintenance fee that will be used to -reimburse: (a) Rohnert Park for operating and maintaining, in good working order, the wastewater collection system in Canon Manor West, and (b) Sonoma County for the costs. of annually maintaining the roads used for access to the wastewater collection system and to properties within Canon Manor West. 6. Rohnert Park and Sonoma County wish to enter into this Agreement pursuant to the authority of, and to satisfy the requirements of, Streets and Highways Code §§10109 through 10111, and specifically Streets and Highways Code § 10110. Agreement 7. OBLIGATIONS SET FORTH IN THIS AGREEMENT CONTINGENT ON THREE EVENTS.
