Record Keeping Requirements (SSMP 7.4)
• Level of Effectiveness: As discussed in the previous section, FOG control program responsibilities transitioned from IWS to WWC in 2016, but during the audit period, IWS operated the program. The City requires in RMC Section 14.14.260 that permitted FSEs retain logbooks on grease control device maintenance cycles, FOG hauling records, sampling data and sludge height monitoring in FOG control devices, BMPs, and records of private lateral SSOs and subsequent mitigation. The recordkeeping requirements and time frames identified in the RMC have enough information necessary for the City to enforce permit requirements of FSEs.
• Recommendations: No modifications recommended at this time.
Legal Authority to Prohibit SSOs and Blockages Caused by FOG Discharges (SSMP 7.5) • Level of Effectiveness: The RMC Section 14.12.050 provides the City with a FOG ordinance and legal authority to require FOG interceptors when deemed necessary by the director. The ordinance prohibits FOG-related blockages and SSOs and limits the maximum allowable concentration of FOG in FSE discharges at the current level of 100 mg/L of wastewater. This ordinance is effective in providing the City with the tools necessary to minimize FOG discharges into the sewer system. • Recommendations: No modifications recommended at this time.
BMP, Grease Removal Devices, Recordkeeping, and Reporting Requirements (SSMP 7.6) • Level of Effectiveness: The City requires all FSEs that discharge FOG to acquire a FOG WDP permit which includes provisions for FSEs to maintain BMPs and grease interceptors, cleaning records, and to report private FOG-related SSOs or blockages. The FOG WDP requirements are effective in providing the City with the tools to limit FOG discharges into the sewer system.
• Recommendations: No modifications recommended at this time.

Inspection and Enforcement Authority – FOG Producers (SSMP 7.7) • Level of Effectiveness: All FSEs that discharge FOG are required to obtain and comply with a City FOG WDP. Under the permit, the FSE must comply with the FOG ordinance as detailed under the RMC, and the City maintains the legal authority to physically inspect the FSE and determine if it is in compliance.
The City possesses effective tools to regulate FOG discharges via a robust FOG ordinance which also requires an effective FSE inspection program. Under oversight from WWC, the City plans on inspecting at least 294 FSEs each fiscal year During this audit, the city documented 0 FSE inspections for FY 18/19, 0 inspections for FY 19/20, and 221 inspections for FY 20/21. The lack of inspections could be due to equipment or due to Covid Pandemic however since only one SSO was caused by FOG, the FOG inspection and enforcement authority element of the SSMP has been effective. • Recommendations: No modifications recommended at this time.
FOG Characterization Assessment and Hot Spot Cleaning Schedule (SSMP 7.8) • Level of Effectiveness: The City has been effective in limiting FOG-related SSOs to one during the threeyear audit period by identifying and placing assets impacted by FOG as a last resort on the hot-spot, high frequency 3-month cleaning list. If the City encounters abnormal FOG levels in a pipe it will first reach out to FSEs and residents that it thinks may be contributing to it and distribute pamphlets to them to minimize FOG discharges. If that does not solve the problem, then the asset is put on the hot-spot list.
Approximately 60% of the 90 hot-spot assets have FOG-related issues that require significant City resources to clean every 3 months.
• Recommendations:
o Modify the EU Engineering GIS database to include hotspot assets and FSEs and add them as layers to the maps that WWC receives.
FOG Control Program Measures (SSMP 7.9)
• Level of Effectiveness: The City has established that all FOG-producing FSEs acquire a FOG WDP which limits discharge of FOG, requires proper O&M records, hauling record, BMPs, and other conditions. The FOG Control Program measure provides the City’s with an effective tool to limit FOG discharges from FSEs.
• Recommendations: No modifications recommended at this time.

5.8.2 Effectiveness of SSMP Elements and Recommended Modifications Evaluation Process – Capacity Enhancement Projects (SSMP 8.2) • Level of Effectiveness: The City has developed two hydraulic simulation models to identify peak flows in the collection system in 2006. In addition, the City developed a new hydraulic model and System Evaluation and Capacity Assurance Plan (SECAP) in 2017, which was done by Woodard and Curran. The modeling efforts conducted in 2006 and 2017 have been effective in evaluating the system and planning for future growth, which is evident from no capacity-deficiency-related SSOs during this audit period. In 2018, Water Works Engineers (WWE) conducted a follow up I/I study upon the existing 2017 model to further analyze results and identify basins and assets with high I/I response. The results of the 2018 I/I study is being actively used by the City as their I/I reduction program base. • Recommendations: Modify Appendix I-1 of the SSMP to indicate that the system evaluation and capacity assurance plan will be reviewed and updated every 10 years. This was also recommended during the previous two audit but has not been implemented.
Design Criteria (SSMP 8.3)
• Level of Effectiveness: The City established a 10-year, 24-hour peak design storm for the hydraulic wet weather loading of the existing collection system along with flow generation factors based on water use records and flow monitoring data. Based on the lack of capacity-related SSOs during the audit period, it appears the City’s capacity design criteria are effective. • Recommendations: No recommended modifications at this time.
Capacity Enhancement Measures (SSMP 8.4)
• Level of Effectiveness: The SPWA Wastewater Systems Evaluation includes the identification of short and long-term Capital Improvement Project (CIP) to meet current and future wastewater flows. The new hydraulic model introduced in 2017 provides new capacity enhancement measures.

• Recommendations: No modifications recommended at this time.
Capital Improvement Program Schedule (SSMP 8.5)
• Level of Effectiveness: The City lists the goal of the CIP is to develop annual project bundles of approximately $1.5 to $2.0 million based on WWC condition assessment data and the hydraulic model CIP results and subsequent flow monitoring or studies. The CIP schedule is effective in identifying the tasks required to assure hydraulic capacity within the collection system. • Recommendations: No modifications recommended at this time.

5.9.2 Effectiveness of SSMP Elements and Recommended Modifications Utility Metrics to Prioritize SSMP Activities (SSMP 9.2) • Level of Effectiveness: The WWC tracks four categories of utility metrics to monitor and measure the effectiveness of the various elements of this SSMP, which include system information, financial information, sewer maintenance, and performance measures. The city also tracks various performance measures related to various SSMP elements and they are summarized in Appendix 7.4. Appendix I has effectively been used to identify and track the specific metrics each of the City’s four categories. • Recommendations: No modifications recommended at this time.
Metrics to Monitor Effectiveness of SSMP (SSMP 9.3)
• Level of Effectiveness: The utility metrics listed in Appendix I-4 pertain to different overseeing departments within the City, and the coordination between these different Departments in measuring/monitoring various metrics and sharing results has been effective in ensuring the SSMP goals have been met.
• Recommendations:
City of Roseville
Sewer System Management Plan (SSMP)
Biennual Audit of FY 18/19 – FY 20/21
October 21 Page 32
o Incorporate system and financial measures recommended in Table 18, from Appendix I-2 into Appendix I-4 and discard Appendix I-2 from the SSMP.
o Update Appendix I-4 and modify it to include document location and review frequency. o Modify I-4 – Key Performance Indicators (KPI) FOG section, to reflect the change in responsibilities from IWS to WWC.
Metrics to Assess Preventative Maintenance Program (SSMP 9.4) • Level of Effectiveness: The City’s current utility metrics Appendix I defines the frequency and type of utility metric that is being tracked to measure SSMP effectiveness. This is effective because it allows the city to monitor performance of particular activities and compare against SSO trends to determined data correlations. These metrics do not all have associated goals or targets, however, which makes it hard to track whether the activity is meeting the intended result. • Recommendations: Consider addition of recommended PM measures in Table 18, from Appendix I-2 into Appendix I-4 and discard Appendix I-2 from the SSMP. The goal is to produce a single living KPI document that can be used to evaluate the effectiveness of SSMP elements.
SSMP Performance Monitoring and Update Process (SSMP 9.5) • Level of Effectiveness: Individual staff oversee various SSMP element performance indicators. The City tracks all revisions/updates with the SSMP using a revision log that is maintained by the LRO. The log is effective documenting changes to the SSMP and encourages the use of the SSMP as a living document. • Recommendations: No modifications recommended at this time.
SSO Trends – Frequency, Location and Volume (SSMP 9.6)
• Level of Effectiveness: The City tracks a comprehensive list of performance metrics that are included in Appendix I-4 of the SSMP and summarized in Table 19. This allows the City to quickly identify and respond to changing trends in SSOs over time. These metrics are monitored on a monthly, quarterly, semi-annual, and annual basis.
• Recommendations:
o Update Appendix I-3 – SSO History (last update 2013). o Update SSO trends data in Appendix I-4 – KPI Benchmarking. o Consider addition of recommended SSO measures in Table 18, from Appendix I-2 into Appendix I-4 and discard Appendix I-2 from the SSMP. The goal is to produce a single living KPI document that can be used to evaluate the effectiveness of SSMP elements.

5.10.2 Effectiveness of SSMP Elements and Recommended Modifications Audit Procedures, Roles, and Responsibilities (SSMP 10.2) • Level of Effectiveness: The City conducts an internal audit biennially to continually measure the effectiveness of the SSMP primarily through evaluating system metrics, performance measures, and reduce SSOs by improving SSMP procedures to better respond to new SSO trends. In addition, the audit evaluates the City’s compliance with SSMP requirements, particularly the amended MRP requirements that were formalized in September 2013. The City developed an audit form as a template to record information produced during the internal SSMP audits. This form is included in SSMP Appendix J-2. The previous audit identified many areas of improvement which the City responded and acted on. Some of these recommended improvements were excluded from this audit based on discussions with the City that eliminated the need for them. Others are considered standing and should still be implemented by the City. Generally, the internal audits implemented by the City have been effective in improving the SSMP and turning it into a living document that that is current, practical, and useful for the City. • Recommendations:
o The SSMP must be recertified by the City Council. Last Certification was completed 4/7/2014.
Per SSS WDR D.14, the City must have the SSMP updated and re-certified by the governing board (i.e. City Council) every five years.
o Post this SSMP internal audit to the City website.
o Schedule the next internal SSMP audit for July-August of 2023. o Develop a description manual to replace Appendix J-1 and J-2 of the SSMP, to support each KPI element. This manual describes required information for KPI monitoring, including but not limited to:

deficiencies and enhancements identified in the audit. As determined in the City’s SSMP revision log, the City has been prompt in responding to audit and continually strives to implement improvements. • Recommendations:
o Update the SSMP change log and add it as an appendix to the SSMP, documenting all changes made to the SSMP since its last certification, indicating when an element was changed/updated and who authorized the change. An example of a change log is shown at Appendix 7.5. This was also recommended during the previous audit but has not been implemented. o Document the submittal process for proposed changes to the SSMP. The process may include the following; identify the individual who maintains the most current version of the SSMP, the steps in which suggested modifications are received (by internal staff or the public), how suggestions are routed to the individual/position responsible for the SSMP element associated with suggested modification, the process for review, and the process for updating the SSMP on the City website and documenting changes.

6. TASK B (Pre-Inspection Conf – Supervisors)
This task included interviews with both collection system Supervisors for further assessing the City’s SSMP compliance, implementation, and effectiveness against several key Reissued WDR requirements. This included reviewing training program, O/M programs, staffing, and other information. Mr. Rodgers and Mr. Wilbanks were very knowledgeable and provided clear answers to the majority of the questions asked during the inspection.
The Supervisors were asked questions jointly about things going well, best practices in place, and recommendations for what could further be improved. They both agreed with Mr. Pruden regarding the need to further improve the City’s existing training program and are concerned about having many inexperienced staff with less than 5 years of actual practical collection system maintenance experience. The Supervisors had some uncertainty with a number of the answers to questions about the City’s SSMP documentation, implementation practices of key SSMP elements, and explanation of existing work programs which could be further improved. A list of Areas of Concern (AOC) identified for Task B during the inspection are presented in Table 5 below.

7. TASK C (Field Inspection #1/2 – Brady Pump Station)
This task included interviewing collection system line staff to assess adequacy of the City’s existing program for training line staff for operations of the City’s pump stations to comply with Attachment D-6, Spill Emergency Response Plan, and Attachment D-4.3, Training (see photos C1-C6 below). This included interviews with field operations staff at the Brady station. Detailed questions about the station’s equipment, inspection/maintenance procedures, emergency troubleshooting procedures, and logbook were asked. Although operators were very experienced and knowledgeable, no specific references to standard procedures were cited and many answers asked during the assessment were either incomplete or inconsistent.
Alarms/Emergency Troubleshooting: To assess emergency response and troubleshooting, operators were asked questions about the station’s equipment, operations, and troubleshooting procedures for responding to alarm calls or possible emergencies at the station. No references to SSMP/standard procedures for pump stations were cited by operators.
Logbook: Inspection of the station logbook revealed only very basic entries being logged by operators without detailed information for maintenance activities or resolution of any problems encountered. Operators stated that pumps are serviced on 90-day intervals. However, inspection of the logbook entries revealed the last pump servicing was completed in July 2023.
Alarm Simulation: A high float alarm check was completed. No references to SSMP/standard procedures for pump stations for handling alarms were cited by operators (procedures for pulling float, checking motor control center (MCC) panel, calling wastewater treatment plant to inform them of the test, logging the test in logbook and into CMMS, etc.).
Allowable Downtime: The City completed comprehensive downtime calculations without power for all of its pump stations including the Brady station. The maximum allowable holding time specified for the Brady station is 11 hours (see Photo C3).
Bypassing: The inspection revealed the Brady station does not have a force main bypass valve installed and traditional bypassing would prove difficult due to challenges accessing the force main which flows under the adjacent creek immediately south/southwest of the station. No references to SSMP/standard procedures for pump stations for bypassing were cited by operators.
Spill Appearance Point: Operations staff were unable to quickly reference the lowest upstream spill appearance point for the station.

216 located at 1311 Brady Lane; “high alarm” set
point=96”, “lag start” set point=70”, “lead start set
point=59”, “lead/lag” stop point=27”, “low alarm” set
point=12”, and “low float” set point at 4”).
Task C (Photo C6): Inspection of 2008 original
construction documentation stored in the MCC inside
panel at station.
Task C (Photo C7): Inspection of station logbook; only
basic entries are logged by operators.
Task C (Photo C8): Inspection of “Standard Operating
Procedure/Job Hazard Analysis” form stored in the MCC
inside panel; operations staff were unaware of the form; station operators were also initially unsure of lowest
upstream spill appearance point for station.

8. TASK D (Field Inspection #2/2 – 8800 Sierra College Blvd) This task included assessing the City’s response to addressing a spill originating from an odor complaint submitted to the City for this location (see Spill CIWQS Spill ID #891462 (Attachment X) and photos D1-D8 below). This call originated from a public odor complaint submitted to the City for field assessment and response. The problem was ultimately discovered to be caused by tree root problems within the City’s mainline sewer in this location.
Spill Summary Narrative (from Spill Technical Report submitted in CIWQS): “On Monday, December 4, 2023, the City Wastewater Collection Division received an odor complaint from a resident at 8800 Sierra College Blvd (Slate Creek Apartment Complex). The resident indicated that despite reporting a sulfur-like odor to the property manager, the resident hadn’t seen any action being taken. During the investigation of the odor complaint, the City Wastewater Collection Service Worker followed City standard operating procedures (SOPs) and discovered a sewer manhole (Asset SMH B08-032) located on a 8 inch City sewer main line discharging into a wetlands area located behind the apartment complex. The next downstream manhole (Asset ID) was discovered by the Service Worker to be fully obstructed by tree roots which the City determined after a lengthy investigation the cause of the sewer spill. Upon discovering the spill, the Service worker promptly notified a supervisor, and wastewater crews promptly implemented the City’s Sewer System Management Plan (SSMP) procedures outlined in the Spill Emergency Response Plan (SERP) for containment, control and mitigation of the spill. Due to its entry into the wetlands area which flows into Strap Ravine, the spill was treated as a Category 1. Prompt notification was made to Cal-OES and a control number issued. Following containment of the spill and initiating cleanup, it became apparent that the volume of the spill exceeded 50,000 gallons, which required the need for Water Quality Monitoring and submission of a Technical Report within 45 days as required by Attachment E1 of the Reissued WDR. The City followed all required procedures outlined in its SERP for effective spill investigation, response, and cleanup, including extensive deployment of City staff and resources including Hydro-Vac units, excavators, trash pumps, and washdown water to mitigate the effects of the spill.” Compliance Evaluation Inspection (City of Roseville – 1/30/2024) Page 13/24 Task D (Photo D1): Inspection of former spill site (looking south/southwest); City improved former access and fully restored area immediately following the spill

10. Post-Inspection Findings
The Compliance Evaluation Inspection Report (CEI) was submitted to the City on March 7, 2024. In response, the following information was received from the City providing detailed responses to all Areas of Concern (AOCs) identified during the inspection report.
Areas of Concern (AOC) City Responses
AOC A1: Field staff
training/competency with SERP
competency for pump stations
“All staff receive training once a year on our SOP # 003 “Lift Station Inspection specifically”. They also receive additional training on lift stations once a year when we train of our SERP and SSMP (element 4). Lastly, they receive a separate training on SOP # 042 “Lift Station Overflow Structure”.
Our crews are taught that they have the support of management, and we can be called in any situation to help or advise.”
AOC A2: Communication and
coordination between City dispatch
operators and Collections
management for ensuring all
complaints are promptly assessed
and addressed
“The City of Roseville has a person that answers phones from 0630-1600 five days a week. If they are unavailable, after hours and on weekends we have an answering service that the call rolls over to. Calls received by the answering service are relayed to the Service Worker / On Call personnel.
The city also customer relationship management system that the public can use to contact us as well. We are also notified of odor complaints that are submitted online that the City can quickly respond too. Are communication with regulatory agencies is handled by reporting on CIWQS, spills that are category 1 or over 1000 gallons are reported to OES as required.” AOC A3: LRO training/Data
Submitter training
“LRO and data submitting training is learned on the job and by attending CWEA and Tri State training classes. Additional training is received through consultant training classes as well. All LRO’s and data submitted hold at a minimum a CWEA Collection System maintenance Grade 4 or is a registered PE in California.“
AOC A4: Coordination
(engineering/operations)
“The City of Roseville plans capital improvements through system evaluation and condition assessment. Areas of concern are identified with CCTV, visual observations, modeling and impacts on environmental areas of concern. Projects are scheduled and planned through our Tech Services group and on projects that we bring to them we are highly involved. We are currently working with Tech Services on two areas where we have capacity issues. The projects will upsize the existing mains to allow for more capacity and relieve choke points. Projects that effect the collection system on the development side are handled by our Development Services group and Wastewater Collections is involved in these activities. The actual design we do have input on, but we are not involved so much with the day to day building of the infrastructure. If changes are made in the field, we may not know about them until much later. More oversite is needed by the wastewater Collection staff.
Compliance Evaluation Inspection (City of Roseville – 1/30/2024) Page 20/24 Areas of Concern (AOC) City Responses
AOC A5: Force mains (condition
assessments, monitoring)
A5: The City of Roseville is currently working on a project to complete a full condition assessment of its force mains. As of today, we have not started a full condition assessment of our force mains do to the lack of technology out there. Tech Service is working to find a technology that will work for our small diameter mains. It may come down to excavating and removing a coupon to do our evaluation.
AOC A6: Pump station
coordination (electricians/line
staff)
A6: Wastewater Collection staff are only authorized to operate lift stations with the Hand Off Auto switch. All other electrical work is performed by our Electrical Technicians. These staff members are available 24/7, 365 and have full access to spare / stocked parts that may be required. They can perform electrical work, signal and control wiring, PLC and SCDA programming and troubleshooting.
AOC A7: FOG program
(implementation/enforcement)
A7: The City of Roseville has two full time FOG inspectors that perform public outreach and enforces the City’s municipal code section 14.14. The city relies on two components to control FOG, 1. Cleaning and inspection 2.
Enforcement and education working with our FSE’s. You may also refer to element #7 of our SSMP. We are working with Code Enforcement to apply monetary penalties on an as needed basis. We have developed a program that is currently at the City Attorney’s Office for review where we do the inspection, notification of violation (three times) and then hand of to Code enforce the monetary aspect of the enforcement or the closing of the business. We also have language in the code that we can sever or temporarily stop flow from an establishment.
AOC A8: Maintenance of critical
spare parts, inventory
A8: The City of Roseville has identified critical parts that are required to be on hand for the preventive maintenance and emergency maintenance that may be required. These parts are called out in our SSMP element #4 Operation and Maintenance. All electrical components are maintained in our mechanical maintenance warehouse that is controlled by the electrical technicians at the Dry Creek WWTP. All repair fittings and pipe are warehoused at the Collections building and controlled by the wastewater collections team. As material / components are used they are replaced to maintain a reasonable inventory of required parts. All warehoused material is controlled by a material technician that works in wastewater collections to allow better control of what we need to have on hand.
AOC A9: Improvements (regional
partners, coordination)
A9: More work can be performed here. There is a JPA in place but nothing specific to mutual aid and how that would work in an emergency. We do meet three times a year with our satellite agencies, and we do from time to time reach out to work on and or discuss issues of the day.
Compliance Evaluation Inspection (City of Roseville – 1/30/2024) Page 21/24 Areas of Concern (AOC) City Responses
AOC A10: Improvements (design,
construction standards)
“As stated in element #5 of our SSMP, the City of Roseville maintains design and construction standards with minimum requirements for developers and contractors for installing a complete and operable wastewater collection system. The standard has language that calls out for air and vacuum testing along with CCTV for acceptance. The City of Roseville also has a punch list procedure to communicate unacceptable work to developers and contractors. According to the National Clay Pipe Institute the City of Roseville has the most stringent standard for installation and acceptance in the country.”
AOC A11: Improvements (Cal-OES
notifications, Cat. 1 spills)
“All category 1 and 2 spills are reported to Cal OES with in the required two hours. All information that is required to be reported is given to the Cal OES operator based on the questions that they ask, and a control number is obtained. Should information change there is an option for updating information. Water samples are taken for spills that are greater than 50,000 gallons. See element #6 of our SSMP.”
AOC A12: Improvements (SERP
training for staff/contractors)
“We train on the SERP annually and impromptu classes and testing are conducted through the year. We use an onsite spill simulator to train on spills from a lower lateral clean out and a sewer manhole. Spill volume and start and stop times estimation are trained on as well.” “We respond to calls for service within 20 minutes during business hours and within 40 minutes after hours and on weekend and holidays. We train on containing the spill, eliminating the cause, and mitigating the impacts of the spill. Notifications for category 1 and 2 spills are made as required and all spills are photographed and documented. Spills that require reporting to CIWQS are done so within the required time.”
Compliance Evaluation Inspection (City of Roseville – 1/30/2024) Page 22/24 Areas of Concern (AOC) City Responses
AOC B1: Inexperienced line
staff/SSMP training/competency;
pump station training
B1: While the personnel question may not have answered all the question to the satisfaction of the interviewer it does not mean that they do not know that their job is to protect from dischargers to the environment. The personal questioned were from other crews and do not typically work on lift stations. They have been trained and if they had arrived at a true spill, they would have followed their training to mitigate the issue.
AOC B2: SERP implementation,
trainings, post-spill assessments
B2: All COR WWC staff have been trained on the SERP twice in the last year.
The first training was conducted by the LRO, and a second training was conducted with a consultant. One Source Utility Consulting was used for a half day training along with a spill simulator test for volume estimation, duration and volume recovered. Post spill assessments are completed by the LRO or his supervisors this is not a requirement of the operation staff.
AOC B3: Improvements to critical
spare parts/inventory, controls
B3: The warehousing of critical spare parts is sufficient to handle any issues that we may encounter. To date we have not had a spill due to lack of spare parts. In extreme cases bypass pumping of the lift stations could be performed as well as any mains that we have in our system.
AOC B4: Supplemental Data
Submitter CIWQS training
B4: More training may be warranted here and adding another LRO in Collections should be implemented. Seek out third party training for additional compliance training.
AOC B5: Improvements (regional
partners, coordination)
B5: More work can be performed here. There is a JPA in place but nothing specific to mutual aid and how that would work in an emergency. We do meet three times a year with our satellite agencies.
AOC B6: Improvements (reducing
“hot spots”)
B6: Hot Spots are removed, when possible, by way of CIPP or replacing with new pipe. We also use FOG Inspection and compliance measure to try and reduce Hot Spots. Time has taught us the FOG does stick to CIP so removal of a main does not mean in perpetuity, it can end up back on the list! AOC B7: Improvements
(procedures for addressing system
deficiencies)
B7: Improvements are based on our Vactor operator’s observations and CCTV crews condition assessment. We also contract with outside contractors to perform condition assessment of our larger trunk mains. We recently bypassed pumped and inspected our 63” and 66” in two locations to determine the cause and possible extent of damage after blistering was seen in the 2019 Condition assessment of the same mains. As issues are found through condition assessments of collector’s work orders are created and prioritized for repair. COR has its own in house construction crew and work is performed to make all repairs.
AOC B8: Improvements (FOG
implementation, enforcement)
B8: The City of Roseville has two full time FOG inspectors that perform public outreach and enforces the City’s municipal code section 14.14. The city relies on two components to control FOG, 1. Cleaning and inspection 2.
Enforcement and education working with our FSE’s. You may also refer to element #7 of our SSMP. We work with Code enforcement to apply monetary penalties on an as needed basis.
Compliance Evaluation Inspection (City of Roseville – 1/30/2024) Page 23/24 Areas of Concern (AOC) City Responses
AOC B9: Training/familiarity with
the City’s SSMP and CIWQS
reporting procedures
B9: More hands on training is required for probationary employees and a few of our Journeymen. Personnel can sometimes get placed on a crew for years on end and the day to day knowledge may be lost when asked to fill in on another discipline. We train annually on lift station operations the SERP, WDR and SSMP as well as SOP training for mission essential equipment used for preventive and reactive maintenance.
Areas of Concern (AOC) City Responses
AOC C1: Insufficient answers to
questions related to Standard
Operating Procedures (SOP) for
pump stations
C1: While the answers may have been insufficient at the time the fact is that all employees know that if they arrive at any call for service that if they have any questions or issue, they can always call a supervisor. We can improve in this area; we have created an atmosphere where the crews rely on direction from leads and supervisors. More will be done in this space to make the crews feel they can do this all on their own.
AOC C2: Insufficient answers to
inspection questions related to
Spill Emergency Response Plan
(SERP) implementation procedures,
station equipment, and alarm
response/procedures
C2: There has been training and testing on the SERP and on lift station operations, but this audit shows more work is needed. New testing requirements will be implemented for both the SERP and Lift Station training along with impromptu testing on all our disciplines in wastewater collections.
Areas of Concern (AOC) City Responses
AOC D1: Risks/threats for future
spills in remote areas
D1: The first lesson learned from this spill was the need for a more aggressive and consistent hydro cleaning schedule for easements and open spaces. We have embarked on a new program that has identified all easements and open spaces and prioritized mains that if water were to spill would have the greatest impact on the environment. Second, we have procured an easement machine to better access some of the harder to reach SMH in easements. This machine adds an additional 500’ of reach to the 800’ we have on our Vactor trucks.
AOC D2: SERP training/drills in
remote areas
D2: With our annual training we will be adding an element to cover easements and how to access hard to reach manholes. We will also cover deployment of the easement machine and best practices for working in off site locations. Included in this training we will touch on spill containment and recovery of spilled water as open spaces and easement offer their own unique challenges.
AOC D3: Lack of easement area
access and maintenance
D3: We have identified areas of concern with regards to access. We are working on removing brush and overgrowth in some areas along with installing base rock and building solid access roads in others. The City’s Public Works Department has under construction right now a bike path project that Wastewater Collection worked with them on to gain access to more SMH’s along creeks. There is a second project that is kicking off that Collections is involved that will give us even more access to SMH’s.

ORDER 2022-0103-DWQ December 6, 2022
4 1. INTRODUCTION
This General Order regulates sanitary sewer systems designed to convey sewage. For the purpose of this Order, a sanitary sewer system includes, but is not limited to, pipes, valves, pump stations, manholes, siphons, wet wells, diversion structures and/or other pertinent infrastructure, upstream of a wastewater treatment plant headworks. A sanitary sewer system includes:
• Laterals owned and/or operated by the Enrollee;
• Satellite sewer systems; and/or
• Temporary conveyance and storage facilities, including but not limited to temporary piping, vaults, construction trenches, wet wells, impoundments, tanks and diversion structures.
Sewage is untreated or partially treated domestic, municipal, commercial and/or industrial waste (including sewage sludge), and any mixture of these wastes with inflow or infiltration of stormwater or groundwater, conveyed in a sanitary sewer system.
Sewage contains high levels of suspended solids, non-digested organic waste, pathogenic bacteria, viruses, toxic pollutants, nutrients, oxygen-demanding organic compounds, oils, grease, pharmaceuticals, and other harmful pollutants.
For the purpose of this General Order, a spill is a discharge of sewage from any portion of a sanitary sewer system due to a sanitary sewer system overflow, operational failure, and/or infrastructure failure. Sewage and its associated wastewater spilled from a sanitary sewer system may threaten public health, beneficial uses of waters of the State, and the environment.
This General Order serves as statewide waste discharge requirements and supersedes the previous State Water Resources Control Board (State Water Board) Order 2006-0003-DWQ and amendments thereafter. All sections and attachments of this General Order are enforceable by the State Water Board and Regional Water Quality Control Boards (Regional Water Boards). Through this General Order, the State Water Board requires an Enrollee to:
• Comply with federal and state prohibitions of discharge of sewage to waters of the State, including federal waters of the United States;
• Comply with specifications, and notification, monitoring, reporting and recordkeeping requirements in this General Order that implement the federal Clean Water Act, the California Water Code (Water Code), water quality control plans (including Regional Water Board Basin Plans) and policies;
• Proactively operate and maintain resilient sanitary sewer systems to prevent spills; • Eliminate discharges of sewage to waters of the State through effective implementation of a Sewer System Management Plan;
• Monitor, track, and analyze spills for ongoing system-specific performance improvements; and

3. FINDINGS
3.1. Legal Authorities
3.1.1. Federal and State Regulatory Authority
The objective of the Clean Water Act is to restore and maintain the chemical, physical, and biological integrity of the waters of the United States (33 U.S.C. 1251). The Water Code authorizes the State Water Board to implement the Clean Water Act in the State and to protect the quality of all waters of the State (Water Code sections 13000 and 13160).
3.1.2. Discharge of Sewage
A discharge of untreated or partially treated sewage is a discharge of waste as defined in Water Code section 13050(d) that could affect the quality of waters of the State and is subject to regulation by waste discharge requirements issued pursuant to Water Code section 13263 and Chapter 9, Division 3, Title 23 of the California Code of Regulations.
A discharge of sewage may pollute and alter the quality of the waters of the State to a degree that unreasonably affects the beneficial uses of the receiving water body or facilities that serve those beneficial uses (Water Code section 13050(l)(1)).
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
8 3.1.3 Water Boards Authority to Require Technical Reports, Monitoring, and Reporting Water Code sections 13267 and 13383 authorize the Regional Water Boards and the State Water Board to establish monitoring, inspection, entry, reporting, and recordkeeping requirements. Water Code section 13267(b), authorizes the Regional Water Boards to “require any person who has discharged, discharges, or is suspected of having discharged or discharging, or who proposes to discharge waste within its region… or is suspected of having discharged or discharging, or who proposes to discharge, waste outside of its region that could affect the quality of water within its region shall furnish, under penalty of perjury, technical or monitoring reports which the regional board requires…In requiring those reports, the regional board shall provide the person with a written explanation with regard to the need for the reports and shall identify the evidence that supports requiring that person to provide the reports.” Water Code section 13267(f) authorizes the State Water Board to require this information if it consults with the Regional Water Boards and determines that it will not duplicate the efforts of the Regional Water Boards. The State Water Board has consulted with the Regional Water Boards and made this determination.
The technical and monitoring reports required by this General Order and Attachment E (Notification, Monitoring, Reporting and Recordkeeping Requirements) are necessary to evaluate and ensure compliance with this General Order. The effort to develop required technical reports will vary depending on the system size and complexity and the needs of the specific technical report. The burden and cost of these reports are reasonable and consistent with the interest of the state in protecting water quality, which is the primary purpose of requiring the reports.
Water Code section 13383(a) authorizes the Water Boards to “establish monitoring, inspection, entry, reporting, and recordkeeping requirements… for any person who discharges, or proposes to discharge, to navigable waters, any person who introduces pollutants into a publicly owned treatment works, any person who owns or operates, or proposes to own or operate, a publicly owned treatment works or other treatment works treating domestic sewage, or any person who uses or disposes, or proposes to use or dispose, of sewage sludge.” Section 13383(b) continues, “the state board or the regional boards may require any person subject to this section to establish and maintain monitoring equipment or methods, including, where appropriate, biological monitoring methods, sample effluent as prescribed, and provide other information as may be reasonably required.”
Reporting of spills from privately owned sewer laterals and systems pursuant to section
5.15 (Voluntary Reporting of Spills from Privately-Owned Sewer Laterals and/or Private Sanitary Sewer Systems) of this General Order is authorized by Water Code section 13225(c) and encouraged by the State Water Board, wherein a local agency may investigate and report on any technical factors involved in water quality control provided the burden including costs of such reports bears a reasonable relationship to the need for the report and the benefits to be obtained therefrom. The burden of reporting private spills under section 5.15 (Voluntary Reporting of Spills from Privately-Owned Sewer Laterals and/or Private Sanitary Sewer Systems) is minimal and is outweighed by the benefit of providing Regional Water Boards an opportunity to respond to these spills
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
9 when an Enrollee, which in many cases has a contractual relationship with the owner of the private system, has knowledge of the spills.
3.1.4. Water Board Authority to Prescribe General Waste Discharge Requirements Water Code section 13263(i) provides that the State Water Board may prescribe general waste discharge requirements for a category of discharges if the State Water Board finds or determines that:
• The discharges are produced by the same or similar operations; • The discharges involve the same or similar types of waste; • The discharges require the same or similar treatment standards; and • The discharges are more appropriately regulated under general waste discharge requirements than individual waste discharge requirements.
Since 2006, the State Water Board has been regulating over 1,100 publicly owned sanitary sewer systems (See section 3.1.5 (Previous Statewide General Waste Discharge Requirements) of this General Order). California also has a large unknown number of unregulated privately owned sanitary sewer systems. All waste conveyed in publicly owned and privately owned sanitary sewer systems (as defined in this General Order) is comprised of untreated or partially treated domestic waste and/or industrial waste. Generally, sanitary sewer systems are designed and operated to convey waste by gravity or under pressure; system-specific design elements and system-specific operations do not change the common nature of the waste, the common threat to public health, or the common impacts on water quality. Spills of waste from a sanitary sewer system prior to reaching the ultimate downstream treatment facility are unauthorized and enforceable by the State Water Board and/or a Regional Water Board. Therefore, spills from sanitary sewer systems are more appropriately regulated under general waste discharge requirements.
As specified in Water Code sections 13263(a) and 13241, the implementation of requirements set forth in this Order is for the reasonable protection of past, present, and probable future beneficial uses of water and the prevention of nuisance. The requirements implement the water quality control plans (Basin Plans) for each Regional Water Board and take into account the environmental characteristics of sewer service areas and hydrographic units within the state. Additionally, the State Water Board has considered water quality conditions that could reasonably be achieved through the coordinated control of all factors that affect water quality, costs associated with compliance with these requirements, the need for developing housing within California, and the need to protect sources of drinking water and other water supplies.
3.1.5. Previous Statewide General Waste Discharge Requirements On May 2, 2006, the State Water Board adopted Order 2006-0003-DWQ serving as Waste Discharge Requirements pursuant to Article 4, Chapter 4, Division 7 of the Water Code (commencing with section 13260) for inadvertent discharges to waters of the State. Order 2006-0003-DWQ prohibited discharges of untreated or partially treated sewage. Order 2006-0003-DWQ also required system-specific management, operation, and maintenance of publicly owned sewer systems greater than one mile in length.
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
10 To decrease the impacts on human health and the environment caused by sewage spills, the previous Order required enrollees to develop a rehabilitation and replacement plan that identifies system deficiencies and prioritizes short-term and long-term rehabilitation actions. The previous Order also required enrollees to:
1. Maintain information that can be used to establish and prioritize appropriate Sewer System Management Plan activities; and
2. Implement a proactive approach to reduce spills.
The previous Order required Sewer System Management Plan elements for “the proper and efficient management, operation, and maintenance of sanitary sewer systems, while taking into consideration risk management.”
On July 30, 2013, the State Water Board amended General Order 2006-0003-DWQ with Order WQ 2013-0058-EXEC, Amending Monitoring and Reporting Program for Statewide General Waste Discharge Requirements for Sanitary Sewer Systems.
Many enrollees of Order 2006-0003-DWQ have already implemented proactive measures to reduce sewage spills. Other enrollees, however, still need technical assistance and funding to improve sanitary sewer system operation and maintenance for the reduction of sewage spills.
3.1.6. Existing Memorandum of Agreement with California Water Environment Association
The California Water Environment Association is a nonprofit organization dedicated to providing water industry certifications, training, and networking opportunities. The Association’s Technical Certification Program provides accredited sanitary sewer system operator certification for collection system operators and maintenance workers.
On February 10, 2016, the State Water Board entered into a collaborative agreement with the Association titled Memorandum of Agreement Between the California State Water Resources Control Board and the California Water Environment Association - Training Regarding Requirements Set Forth in Statewide General Waste Discharge Requirements for Sanitary Sewer Systems. The Memorandum sets forth collaborative training necessary for regulated sanitary sewer system personnel to operate and maintain a well operating system and ensure full compliance with statewide sewer system regulations.
On March 15, 2018, the State Water Board and the California Water Environment Association amended the existing Memorandum of Agreement to include collaborative outreach and expand training needs associated with further updates to Water Board regulations for sanitary sewer systems. The State Water Board encourages further Agreement updates as necessary to support improved sewer system operations and the professionalism of collection system operators.

ORDER 2022-0103-DWQ December 6, 2022
11 3.2. General
3.2.1. Waters of the State
Waters of the State include any surface water or groundwater, including saline waters, within the boundaries of the state as defined in Water Code section 13050(e), and are inclusive of waters of the United States.
3.2.2. Sanitary Sewer System Spill Threats to Public Health and Beneficial Uses Sewage contains high levels of suspended solids, pathogenic organisms, toxic pollutants, nutrients, oxygen-demanding organic compounds, oil and grease and other pollutants. Sewage spills may cause a public nuisance, particularly when sewage is discharged to areas with high public exposure such as streets and surface waters used for drinking, irrigation, fishing, recreation, or other public consumption or contact uses.
More specifically, sanitary sewer spills may:
• Adversely affect aquatic life and/or threaten water quality when reaching receiving waters;
• Inadvertently release trash, including plastics;
• Impair the recreational use and aesthetic enjoyment of surface waters by polluting surface water or groundwater;
• Threaten public health through direct public exposure to bacteria, viruses, intestinal parasites, and other microorganisms that can cause serious illness such as gastroenteritis, hepatitis, cryptosporidiosis, and giardiasis; • Negatively impact ecological receptors and biota within surface waters; and • Cause nuisance including odors, closure of beaches and recreational areas, and property damage.
Sanitary sewer system spills may pollute receiving waters and threaten beneficial uses of surface water and groundwater. Potentially threatened beneficial uses include, but are not limited to the following (with associated acronym representations as included in statewide water quality control plans and Regional Water Boards’ Basin Plans):
• Municipal and Domestic Supply (MUN)
• Water Contact Recreation (REC-1) and Non-Contact Water Recreation (REC-2) • Cold Freshwater Habitat (COLD)
• Warm Freshwater Habitat (WARM)
• Native American Culture (CUL)
• Wildlife Habitat (WILD)
• Rare, Threatened, or Endangered Species (RARE)
• Spawning, Reproduction, and/or Early Development (SPWN) • Wetland Habitat (WET)
• Agricultural Supply (AGR)
• Estuarine Habitat (EST)

• Groundwater Recharge (GWR)
• Inland Saline Water Habitat (SAL)
3.2.3. Proactive Sanitary Sewer System Management to Eliminate Spill Causes Finding 3 of the previous Order, 2006-0003-DWQ, states: “Sanitary sewer systems experience periodic failures resulting in discharges that may affect waters of the state.
There are many factors (including factors related to geology, design, construction methods and materials, age of the system, population growth, and system operation and maintenance), which affect the likelihood of an SSO [sanitary sewer overflow].
A proactive approach that requires Enrollees to ensure a system-wide operation, maintenance, and management plan is in place will reduce the number and frequency of SSOs within the state. This approach will in turn decrease the risk to human health and the environment caused by SSOs.”
Many spills are preventable through proactive attention on sanitary sewer system management using the best practices and technologies available to address major causes of spills, including but not limited to:
• Blockages from sources including but not limited to:
o Fats, oils and grease;
o Tree roots;
o Rags, wipes and other paper, cloth and plastic products; and o Sediment and debris.
• Sewer system damage and exceedance of sewer system hydraulic capacity from identified system-specific environmental, and climate-change impacts, including but not limited to:
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
13 o Sea level rise impacts including flooding, coastal erosion, seawater intrusion, tidal inundation and submerged lands;
o Increased surface water flows due to higher intensity rain events; o Flooding;
o Wildfires and wildfire induced impacts;
o Earthquake induced damage;
o Landslides; and
o Subsidence.
• Infrastructure deficiencies and failures, including but not limited to:
o Pump station mechanical failures;
o System age;
o Construction material failures;
o Manhole cover failures;
o Structural failures; and
o Lack of proper operation and maintenance.
• Insufficient system capacity (temporary or sustained), due to factors including but not limited to:
o Excessive and/or increased storm or groundwater inflow/infiltration; o Insufficient capacity due to population increase and/or new connections from industrial, commercial and other system users; and
o Stormwater capture projects utilizing a sanitary sewer system to convey stormwater to treatment facilities for reuse.
• Community impacts, including but not limited to:
o Power outages;
o Vandalism; and
o Contractor-caused or other third party-caused damages.
3.2.4. Underground Sanitary Sewer System Leakage
Portions of some sanitary sewer systems may leak, causing underground exfiltration (exiting) of sewage from the system. Exfiltrated sewage that remains in the underground infrastructure trench and/or the soil matrix, and that does not discharge into waters of the State (surface water or groundwater) may not threaten beneficial uses.
Underground exfiltrated sewage may threaten beneficial uses if discharged to waters of the State. Exfiltrated sewage that discharges to groundwater may impact beneficial uses of groundwater and pollute groundwater supply. Additionally, if in close proximity, exfiltrated sewage may enter into a compromised underground drainage conveyance system that discharges into a water of the United States, or into groundwater that is hydrologically connected to (feeds into) a water of the United States, thus potentially causing: (1) a Clean Water Act violation, (2) threat and impact to beneficial uses, and/or (3) surface water pollution.
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
14 3.2.5. Proactive Sanitary Sewer System Management to Reduce Inflow and Infiltration Excessive inflow (stormwater entering) and infiltration (groundwater seepage entering) to sanitary sewer systems is preventable through proactive sewer system management using the best practices and technologies available. The efficiency of the downstream wastewater treatment processes is dependent on the performance of the sanitary sewer system. When the structural integrity of a sanitary sewer system deteriorates, high volumes of inflow and infiltration can enter the sewer system. High levels of inflow and infiltration increase the hydraulic load on the downstream treatment plant, which can reduce treatment efficiency, lead to bypassing a portion of the treatment process, cause illegal discharge of partially treated effluent, or in extreme situations make biological treatment facilities inoperable (e.g., wash out the biological organisms that treat the waste).
3.3. Water Quality Control Plans, Policies and Resolutions The nine Regional Water Boards have adopted region-specific water quality control plans (commonly referred to as Basin Plans) that designate beneficial uses, establish water quality objectives, and contain implementation programs and policies to achieve those objectives. The State Water Board has adopted statewide water quality control plans, policies and resolutions establishing statewide water quality objectives, implementation programs and initiatives.
3.3.1. State Water Board Antidegradation Policy
On October 28, 1968, the State Water Board adopted Resolution 68-16, titled Statement of Policy with Respect to Maintaining High Quality of Waters in California, which incorporates the federal antidegradation policy. Resolution 68-16 requires that existing water quality be maintained unless degradation is justified based on specific findings.
The continued prohibition of sewage discharges from sanitary sewer systems into waters of the State aligns with Resolution 68-16. A sewage discharge from sanitary sewers to waters of the State is prohibited by this Order. Therefore, this Order does not allow degradation of waters of the State. In addition, this Order: (1) further expands the existing prohibition of sewage discharges to include waters of the State, in addition to waters of the United States as provided in previous Order 2006-0003-DWQ, and (2) enhances the ability for Water Board enforcement of violations of the established prohibitions.
3.3.2. State Water Board Sources of Drinking Water Policy On May 19,1988, the State Water Board adopted Resolution 88-63 (amended on February 1, 2006), titled Sources of Drinking Water, establishing state policy that all waters of the State, with certain exceptions, are suitable or potentially suitable for municipal or domestic supply.
3.3.3. State Water Board Cost of Compliance Resolution
On September 24, 2013, the State Water Board adopted Resolution 2013-0029, titled Directing Actions in Response to Efforts by Stakeholders on Reducing Costs of
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
15 Compliance While Maintaining Water Quality Protection. Through this resolution, the State Water Board committed to continued stakeholder engagement in identifying and implementing measures to reduce costs of compliance with regulatory orders while maintaining water quality protection and improving regulatory program outcomes.
3.3.4. State Water Board Human Right to Water Resolution On February 16, 2016, the State Water Board adopted Resolution 2016-0010, titled Adopting the Human Right to Water as a Core Value and Directing its Implementation in Water Board Programs and Activities, addressing the human right to water as a core value and directing Water Board programs to implement requirements to support safe drinking water for all Californians.
On November 16, 2021, the State Water Board adopted Resolution 2021-0050 titled Condemning Racism, Xenophobia, Bigotry, and Racial Injustice, and Strengthening Commitment to Racial Equity, Diversity, Inclusion, Access, and Anti-racism. Among other actions, through Resolution 2021-0050, the State Water Board, in summary as corresponding to this General Order, reaffirms its commitment to its Human Right to Water resolution, upholding that every human being in California deserves safe, clean, affordable, and accessible water for human consumption, cooking, and sanitation purposes. Resolution 2021-0050 provides the State Water Board commitment to:
• Protect public health and beneficial uses of waterbodies in all communities, including communities disproportionately burdened by wastes discharge of waste to land and surface water;
• Restore impaired surface waterbodies and degraded aquifers; and • Promote multi-benefit water quality projects.
Through Resolution 2021-0050, the State Water Board also commits to expanding implementation of its Climate Change Resolution to address the disproportionate effects of extreme hydrologic conditions and sea-level rise on Black, Indigenous, and people of color communities, prioritizing:
• The right to safe, clean, affordable, and accessible drinking water and sanitation; • Sustainable management and protection of local groundwater resources; • Healthy watersheds; and
• Access to surface waterbodies that support subsistence fishing.
On June 7, 2022, the State Water Board adopted a Resolution, titled Authorizing the Executive Director or Designee to Enter into One or More Multi-Year Contracts Up to a Combined Sum of $4,000,000 for a Statewide Wastewater Needs Assessment, supporting the equitable access to sanitation for all Californians and implementation of Resolutions 2016-0010 and 2021-0050.
This General Order supports the State Water Board priority in collecting a comprehensive set of data for California’s wastewater systems, including sanitary sewer systems. Data reported per the requirements of this Order will be used with data from other Water Boards’ programs, to further develop criteria and create a statewide risk
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
16 framework to prioritize critical funding and infrastructure investments for California’s most vulnerable populations, including disadvantaged or severely disadvantaged communities with inadequate or failing sanitation systems and threatened access to healthy drinking water supplies.
3.3.5. State Water Board Open Data Resolution
On July 10, 2018, the State Water Board adopted Resolution 2018-0032, titled Adopting Principles of Open Data as a Core Value and Directing Programs and Activities to Implement Strategic Actions to Improve Data Accessibility and Associated Innovation, directing regulatory programs to assure all monitoring and reporting requirements support the State Water Boards’ Open Data Initiative.
3.3.6. State Water Board Response to Climate Change
On March 7, 2017, the State Water Board adopted Resolution 2017-0012, titled Comprehensive Response to Climate Change, requiring a proactive response to climate change in all California Water Board actions, with the intent to embed climate change consideration into all programs and activities.
3.4. California Environmental Quality Act
The adoption of this Order is an action to reissue general waste discharge requirements that is exempt from the California Environmental Quality Act (Public Resources Code section 21000 et seq.) because it is an action taken by a regulatory agency to assure the protection of the environment and the regulatory process involves procedures for protection of the environment (Cal. Code Regs., Title 14, section 15308). In addition, the action to adopt this Order is exempt from CEQA pursuant to Cal. Code Regs., Title 14, section 15301, to the extent that it applies to existing sanitary sewer collection systems that constitute “existing facilities” as that term is used in sections 15301 and 15302, to the extent that it results in the repair or replacement of existing systems involving negligible or no expansion of capacity.
3.5. State Water Board Funding Assistance for Compliance with Water Board Water Quality Orders
The State Water Board, Division of Financial Assistance administers the implementation of the State Water Board financial assistance programs, per Board-adopted funding policies. Among other funding areas, the Division administers loan and grant funding for the planning and construction of wastewater and water recycling facilities per funding program-specific policies and guidelines. Applicants may apply for Clean Water State Revolving Fund low-interest loan, Small Community Wastewater grant funding assistance, and other funding available at the time of application, for some of the costs associated with complying with this General Order.

The State Water Board also considers loan forgiveness on a disadvantaged community-specific basis.
For disadvantaged communities’ wastewater needs, the State Water Board places priority on the funding of projects that address:
• Public health;
• Violations of waste discharge requirements and National Pollutant Discharge Elimination System (NPDES) permits;
• Providing sewer system service to existing septic tank owners; and • High priority public health and water quality concerns identified by a Regional Water Board.

LIST OF TERMS
Authorized Representative – The person designated, for a municipality, state, federal, or other public agency, as either a principal executive officer or ranking elected official or a duly authorized representative of that person.
Blockage – Something that partially or fully blocks the wastewater from flowing through a sewer pipeline. The blockage can be caused by debris in the sewer, grease buildup, root intrusion, or a partial or complete pipeline collapse. If not caught in time, the blockage may cause an overflow.
California Association of Sanitation Agencies (CASA) - CASA is a non-profit, statewide trade association representing public agencies that provide wastewater collection, treatment, disposal, and/or water reclamation services to about 90 percent of the sewered population in California.
Website: http://www.casaweb.org/
California Water Environment Association (CWEA) – CWEA is an association of 8,000-plus professionals in the wastewater industry. CWEA is committed to keeping California's water clean.
CWEA trains and certifies wastewater professionals, disseminates technical information, and promotes sound policies to benefit society by protecting and enhancing the water environment. CWEA offers services at the state level and locally through 17 local geographical sections. In addition, through their on-line bookstore, CWEA offers technical references for sewer system operation and maintenance.
Website: http://www.cwea.org/ .
Central Valley Clean Water Association (CVCWA) – CVCWA is an association comprised of over 50 wastewater treatment and collection system agencies. CVCWA’s mission is to effectively represent the interests of public wastewater agencies in the Central Valley in regulatory matters and to support the exchange of information so members can best meet their business challenges.
Website: http://www.cvcwa.org/ .
Central Valley Regional Water Quality Control Board – Also known as Regional Water Board or RWQCB. The mission of this state regulatory agency is to: preserve, enhance, and restore the quality of California's water resources, and ensure their proper allocation and efficient use for the benefit of present and future generations. Website: http://www.waterboards.ca.gov/centralvalley/ .
Dynamic Model – Computer hydraulic model simulation which solves the complete dynamic flow routing equations (St. Venant’s equations) for accurate simulation of backwater, looped connections, surcharging, and pressure flow in a collection system.
Enrollee – The legal public entity that owns a sanitary sewer system, as defined by the GWDR, which has submitted a complete and approved application for coverage under the GWDR. This is also called a sewer system agency or wastewater collection system agency.
Fats, Oils and Grease (FOG) - Fats, oils, and grease that are discharged into the sanitary sewer collection system by Food Service Establishments (FSE), homes, apartments, and other sources. FOG is a major cause of blockages leading to increased maintenance and sometimes SSOs. 13 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
FOG Control Program – To be implemented at the Enrollee’s discretion. May include public education program; plan and schedule for the disposal of FOG; legal authority to prohibit FOG related discharges; requirement to install grease removal devices; authority to inspect grease producing facilities; identification of sanitary sewer system sections subject to FOG blockages and the establishment of a cleaning schedule for each section; development and implementation of source control measures for all sources of FOG.
Geographical Information System (GIS) – A database linked with mapping, which includes various layers of information used by government officials. Examples of information found on a GIS can include a sewer map; sewer features such as pipe location, diameter, material, condition, last date cleaned or repaired. The GIS also typically contains base information such as streets and parcels.
Governing Board – This is the governing board of the sewer entity developing the SSMP. Examples would be the Board of Directors, the City Council, or the County Board of Supervisors.
GWDR – General Waste Discharge Requirements – A GWDR is an authorization to discharge waste with certain conditions, which can be issued on an individual basis or to a group of dischargers. The Statewide General WDR for Sanitary Sewer Systems was adopted by the SWCRB and will be implemented by the Regional Water Boards and SWRCB.
Infiltration – The seepage of groundwater into a sewer system, including service connections. Seepage frequently occurs through defective or cracked pipes, pipe joints, connections or manhole walls and joints.
Inflow – Water discharged into a sewer system and service connections from such sources as, but not limited to, roof leaders, cellars, yard and area drains, foundation drains, cooling water discharges, drains from springs and swampy areas, around manhole covers or through holes in the covers, cross connections from storm and combined sewer system, catch basins, storm waters, surface runoff, street wash waters or drainage. Inflow differs from infiltration in that it is a direct discharge into the sewer rather than a leak into the sewer itself.
Lateral – The portion of sewer that connects a home or business with the main line in the street.
Sometimes sewer system agencies own or maintain a portion of the lateral.
Upper Lateral: Portion of lateral from building to property line (or easement line), usually privately owned and maintained.
Lower Lateral: Portion of lateral from property line (or easement line) to sewer mainline in the street or easement. This portion of the lateral is sometimes privately owned and maintained and sometimes publicly owned and maintained.
Monitoring and Reporting Program - The Monitoring and Reporting Program established in the WDR that establishes monitoring, record keeping, reporting and public notification requirements for the GWDR.
14 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
Overflow Emergency Response Plan – Identifies measures to protect public health and the environment. A plan must include the following: notification procedure, appropriate response plan, regulatory notification procedures, employee training plan, procedures to address emergency operations, a program that ensures all reasonable steps are taken to contain and prevent discharges.
Private Lateral: That portion of the Lateral that is owned and maintained by the private property owner that it serves. Based on an individual agency’s ordinance, this may just be the Upper Lateral or can include the Lower Lateral.
Preventative Maintenance (PM) – Regularly scheduled servicing of machinery, infrastructure or other equipment using appropriate tools, tests, and lubricants. This type of maintenance can prolong the useful life of equipment, infrastructure, and machinery and increase its efficiency by detecting and correcting problems before they cause a breakdown of the equipment, or failure of the infrastructure.
R-Value – Is the amount of rainfall that reaches the collection system via infiltration and inflow. This value is typically expressed as a percentage of total rainfall volume that reaches the collection system.
Regional Water Board – Is a short name for any of the nine regional boards including the San Francisco Bay Area Regional Water Quality Control Board and the Central Valley Regional Water Quality Control Board.
Rehabilitation and Replacement Plan (also referred to as a Capital Improvement Plan) – Identifies and prioritizes system deficiencies and implements short-term and long-term rehabilitation actions to address each deficiency.
Sanitary Sewer Overflow (SSO) – The Statewide GWDR defines an SSO as any overflow, spill, release, discharge, or diversion of untreated or partially treated wastewater from a sanitary sewer system, including overflows or releases that reach waters of the United States, overflows or releases that do not reach water of the United States, and backups into buildings and/or private property caused by conditions within the publicly owned portion of the sewer system.
Sanitary Sewer Overflow Categories
Category 1 – Discharges of untreated or partially treated wastewater of any volume resulting from an enrollee’s sanitary sewer system failure or flow condition that:
• Reach surface water and/or reach a drainage channel tributary to surface water • Reach a Municipal Separate Storm Sewer System (MS4) and are not fully captured and returned to the sanitary sewer system or not otherwise captured and disposed of properly. Any volume of wastewater not recovered from the MS4 is considered to have reached surface water unless the storm drain system discharges to a dedicated storm water or groundwater infiltration basin. 15 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
Category 2 – Discharges of untreated or partially treated wastewater of 1,000 gallons or greater resulting from an enrollee’s sanitary sewer system failure or flow condition that do not reach surface water, a drainage channel, or a MS4 unless the entire SSO discharged to the storm drain system is fully recovered and disposed of properly.
Category 3- All other discharges of untreated or partially treated wastewater resulting from an enrollee’s sanitary sewer system failure or flow condition Private Lateral Sewage Discharges – Discharges of untreated or partially treated wastewater resulting from blockages or other problems within a privately owned sewer lateral connected to the enrollee’s sanitary sewer system or from other private sewer assets. PLSDs that the enrollee becomes aware of may be voluntarily reported to the CIWQS Online SSO Database.
Sanitary Sewer Systems – Any system of pipes, pump stations, sewer lines, or other conveyances, upstream of a wastewater treatment plant head works used to collect and convey wastewater to the publicly owned treatment facility. Temporary storage and conveyance facilities are part of the sanitary sewer system and discharges into these temporary storage facilities are not to be considered SSOs.
Satellite Collection System – The portion, if any, of a sanitary sewer system owned or operated by a different public agency than the agency that owns and operates the wastewater treatment facility to which the sanitary sewer system is tributary.
Sewer System Management Plan-SSMP – A series of written site-specific programs that address how a collection system owner/operator conducts their daily business as is outlined in the WDR. Each SSMP is unique for an individual discharger. The plan includes provisions to provide proper and efficient management, operation, and maintenance of sanitary sewer systems, while taking into consideration risk management and cost benefit analysis. Also, must contain a spill response plan. Certification is offered by technically qualified and experienced persons and provides a useful cost-effective means for ensuring that SSMPs are developed and implemented appropriately.
Stakeholder - A person or organization that has a vested interest in the development and outcome of the SWRCB Order No. 2006-0003 Statewide General Waste Discharge Requirements for Sanitary Sewer Systems.
State Water Resources Control Board: Also called the State Board. This is the State agency that developed and passed the GWDR for collection systems and the agency that maintains the SSO reporting web site.
Static Model – A computer hydraulic model that uses the Manning’s Equation to determine hydraulic capacity of the gravity pipelines and either the Manning’s or Hazen-Williams Equations to determine the hydraulic capacity of the pressure pipeline system. The capacity is compared to the peak hydraulic flow in the system to determine potential deficiencies. The static model assumes the peak hydraulic flow occurs at all locations within the collection system at the same time. 16 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
Stoppage – Something that partially or fully blocks the wastewater from flowing through a sewer pipeline. A stoppage can be caused by debris in the sewer, grease buildup, root intrusion, or a partial or full collapse of the pipeline. If not caught in time, a stoppage may cause an overflow. This is also called a blockage.
System Evaluation and Capacity Assurance Plan – A required component of an agency’s SSMP and is an important part of any agency’s overall Capital Improvement Plan that provides hydraulic capacity of key sanitary sewer system elements for dry weather peak flow conditions, as well as the appropriate design storm or wet weather event.
Wastewater Collection System: See Sanitary Sewer System. 17 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
EXECUTIVE SUMMARY
The City of Roseville (City) is a Council-Manager form of government in which responsibilities are vested in the City Council and City Manager. In this form of government, the City Council’s role is that of a legislative policy-making body which determines not only local laws that regulate community life, but also determines public policy and gives direction to the City Manager. The City Manager administers the affairs of the city government in a business-like prudent manner.
The City’s Public Utilities Commission studies and advises the City Council on all utility issues related to city-owned utilities (electric, water, sewer, and solid waste).
The City’s Wastewater Utility is one of five utilities operated in the Environmental Utilities Department (EUD). The Wastewater Utility is responsible for operation and maintenance of all wastewater facilities owned by the City including the Publicly Owned Treatment Works (POTWs), the wastewater collection system, the water quality lab and the recycled water utility.
The City’s Wastewater Collection (WWC) Division is a division of Environmental Utilities Department (EUD). The WWC Division is responsible for management, operation, maintenance, and capacity assurance of the City’s sanitary sewer collection system, including inspecting, cleaning, repairing, and monitoring the gravity sewer lines, force mains, and lift station.
The City initiated a Sewer System Management Plan (SSMP) assessment in 2005 to evaluate how well the Wastewater Collection (WWC) Division would comply with the anticipated State Water Resources Control Board (SWRCB) Statewide General Waste Discharge Requirements (WDR) order No. 2006-0003 for Sanitary Sewer Systems. That SSMP assessment indicated that the City was positioned fairly well to comply with the SWRCB’s SSMP requirements.
In March of 2007, the WWC division along with consultant assistance, began writing the SSMP and reviewing all remaining policies, procedures, and programs to comply with the SWRCB’s WDR.
The plan described how the City would address each element of the SSMP contained in the SWRCB’s WDR to eliminate preventable Sanitary Sewer Overflows (SSOs). The WWC staff completed the development of the SSMP, which the City Council approved on 21 JAN 09.
The city continues to monitor, measure, and modify the existing SSMP as changes and program improvements are identified. The city has developed a Key Performance Indicator worksheet, which is used to monitor and measure the effectiveness of the various elements of the SSMP.
Roseville’s SSMP has been audited five times since being certified by the SWRCB. 18 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
SERVICE AREA AND RELEVANT STATISTICS
Figure-1 illustrates the boundary of Roseville’s geographical service area. Statistics provided in this SSMP are from August 2021 and are gathered from the City’s Economic Development website, https://www.roseville.ca.us/government/departments/economic_development/demographics.
The City service area is approximately 44.20 square miles, has approximately 48,734 residential, 1,932 commercial and 600 industrial sewer connections and 2 Regional Wastewater Treatment Plants.
The WWC Division provides service to approximately 146,875 sewer customers. The wastewater collection and conveyance system consist of 871 miles sewer pipe ranging from 4”to 84” in diameter, 12,538 manholes, and 17 neighborhood lift stations that convey an average dry weather flow of approximately 18.5 MGD. Sanitary sewerage is conveyed from the City’s East boundaries Figure 1 Roseville Service Area
19 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
to the Dry Creek Wastewater Treatment Plant and from its North and West boundaries to the Pleasant Grove Wastewater treatment plant.
WWC Division statistical records indicate that prior to the creation of this SSMP it has had a moderate Sanitary Sewer Overflow (SSO) rate in comparison to other communities in California of similar size and complexity. In the years prior to adoption of the SSMP, the WWC Division had experienced approximately 168 SSOs releasing approximately 15,203 gallons of sewage from the sanitary sewer collection and conveyance system. Since adoption of the SSMP in 2007, the city has experienced a combined 431 SSOs releasing approximately 15,435 gallons of sewage from the sanitary sewer system. Of that total, 11,219 gallons or 82%, have been captured and returned to the sanitary sewer system. The majority of these SSO have occurred from blockages in service laterals.
Since the adoption of the SSMP, the average volume spilled per SSO has been less than 36 gallons/event. All SSOs have been mitigated in a timely manner and have not negatively affected public health or the environment.
The purpose of this SSMP is to describe the activities the WWC Division uses to manage the City’s’ wastewater collection system to further eliminate preventable SSOs, minimize those SSOs that do occur and protect both public health and the environment. 20 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
0 SSMP Overview
The City of Roseville is required to comply with the State Water Resources Control Board Order No. 2006-0003-DWQ adopted May 2, 2006, entitled Statewide General Waste Discharge Requirements for Sanitary Sewer Systems.
The purpose of the Order is to prevent Sanitary Sewer Overflows (SSO) or sewer spills by establishing a statewide Monitoring and Reporting Program (MRP) and requiring each local or regional sewer agency to create and implement their own Sewer System Management Plan (SSMP) based on the mandatory requirements of the Order. The MRP requires each local or regional sewer agency to appoint a legally responsible official and establish a monitoring and reporting organization to monitor and report all SSOs in accordance with the requirements of the MRP and to have the LRO certify the SSO report using the California Integrated Water Quality System (CIWQS) website in the timeframe required by the Order.
The City of Roseville developed a Sewer System Management Plan specific to the wastewater collection system operated and maintained by wastewater collection personnel in the City of Roseville. This SSMP documents the activities the city will utilize to manage, operate, and maintain its wastewater collection system. The city shall take all steps feasible to eliminate SSOs, but in the event an SSO does occur, will take all steps necessary to contain and mitigate the negative impacts of an SSO.
The city’s SSMP is organized comparable to paragraph D. 13 of the general order. The SSMP includes eleven elements, and each of these elements forms a corresponding chapter in the SSMP.
The eleven elements are listed below.
1. Goals- The goal is to prevent and/or reduce SSOs and mitigate the effect of any SSOs that do occur.
The goal requires a plan and schedule to properly manage, operate, and maintain all parts of the sanitary sewer collection system.
2. Organization- The SSMP must identify the Legally Responsible Official or authorized representative as described in the Order. It must list and identify the organization positions responsible for operating and maintaining the sanitary sewer collection system including names and telephone numbers for management, administrative and maintenance positions, and the chain of communication for reporting SSOs
3. Legal Authority- Each enrollee must demonstrate through ordinances, agreements, or other legally binding procedures that they possess the legal authority to meet the requirements of the general order.
4. Operation and Maintenance Program- The SSMP must include those items that are appropriate and applicable to the enrollee’s system, including an up to date mapping system, ability to describe the O&M activities performed on the system, have a plan to develop a rehabilitation and replacement plan, and to provide training on a regular basis for collection system personnel. 21 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
5. Design and Performance Provisions- The SSMP must demonstrate that the sewer agency has and appropriately uses design and construction standards and specifications for the installation of new sewer systems, rehabilitation and repair of existing sewer systems and has procedures and standards for inspecting and testing the installation of new sewers, pumps, etc. and for rehabilitation and repair projects.
6. Overflow Emergency Response Plan- Each Enrollee shall develop and implement an overflow emergency response plan that identifies measures to protect public health and the environment.
7. Fog Control Program- Each Enrollee shall evaluate its sewer system and determine if a Fats, Oils and Grease control program is needed. The FOG control plan, if needed, must meet all the requirements of the Order.
8. System Evaluation and Capacity Assurance Plan- The Enrollee shall prepare and implement a capital improvement plan (CIP) that provides hydraulic capacity of key sanitary sewer system elements for dry weather peak flow conditions, as well as the appropriate design for storm or wet weather events
9. Monitoring, Measurement and Program Modifications- The enrollee shall maintain relevant information to establish and prioritize SSMP activities, monitor the implementation and measure the effectiveness of the SSMP activities, and provide assessment of the performance and/or modification of the SSMP activities as required by the Order.
10. SSMP Program Audits - The Enrollee shall conduct periodic internal audits, appropriate to the size of the system and the number of SSOs. At a minimum, these audits must occur every two years and a report must be prepared and kept on file. This audit shall focus on evaluating the effectiveness of the SSMP
11. Communication Program- The Enrollee shall communicate on a regular basis with the public on the development, implementation, and performance of its SSMP. The communication system shall provide the public the opportunity to provide input to the Enrollee as the program is developed and implemented. The program shall also include a communication plan with tributary and satellite systems to the enrollee’s sanitary sewer system

SSMP ELEMENT 1
1 Goals
D.13. (i) The goal of the SSMP is to provide a plan and schedule to properly manage, operate, and maintain all parts of the sanitary sewer system. This will help reduce and prevent SSOs, as well as mitigate any SSOs that do occur.
1.1 Roseville’s Goals
The City’s WWC Division has established eight goals to guide the implementation, and success of Roseville’s SSMP. These goals are designed to facilitate and target the management, operation, and maintenance of the sanitary sewer collection system in a manner that will sustain the infrastructure, protect public health and the environment, and achieve compliance with State Water Resources Control Board’s General Waste Discharge Requirement (GWDR) for Sanitary Sewer Systems. These goals include:
1. Properly manage, operate, and maintain all portions of the City’s wastewater collection system.
2. Provide adequate capacity to convey peak wastewater flows.
3. No repeat overflows from the same location.
4. Maintain a rate of SSO/100 miles of pipe, that is lower than the state and regional average.
5. Maintain a recovery rate for SSO/100 miles of pipe, that is higher than the state and regional average.
6. Mitigate the impacts that are associated with all SSOs that may occur.
7. Comply with all applicable regulatory notification and reporting requirements.
8. Maintain high design and construction standards for new and rehabilitated infrastructure.
1.2 Element Objectives
The WWC Division provides a safe, effective, and efficient wastewater collection and conveyance system through preventative maintenance, engineering, and customer services. The Division also provides twenty-four-hour emergency services to respond to system failures, minimize sanitary sewer overflows, comply with regulatory mandates, and ensure public health and safety.
The City allocates adequate resources for the operation, maintenance, and repair of its sanitary sewer system, by establishing a proper rate structure, accounting mechanisms, and auditing procedures to ensure an adequate measure of revenues and expenditures.
In addition, the City has stringent design and construction standards for new or rehabilitated infrastructure, with an inspection program that ensures city standards are adhered to. 23 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22

Either the Administration Technician or service call worker receives all service calls during regular business hours. If received in the office, a service request is created with the caller information, the problem, and contact information. This information is transferred to the service call worker, in which they respond, access the problem, and provide a solution. An answering service, contracted by WWC Division, receives all after-hours calls to gather information and dispatch to the on-call service worker via an assigned mobile phone. The on-call service worker is available 24 hours per day and is furnished with a service van and equipment to facilitate a timely response. A response time goal is 20 minutes during business hours and 40 minutes for after-hour service calls. The van is equipped with containment devices to manage lower lateral blockages and spills, and to prevent SSOs from entering a storm drain inlet or channel. Should the situation require additional resources, the on-call worker would contact crew members from the call-out sheet for assistance. Table 2-1, included in the division’s SSOERP, summarizes the chain of communication when receiving calls for service.

SSMP ELEMENT 4
4 Operation and Maintenance
D.13.(iv) The SSMP must include those elements listed below that are appropriate and applicable to the enrollee’s system. This chapter describes the city’s activities regarding mapping systems of the sanitary sewer system, operation and preventative maintenance activities, rehabilitation and replacement program, training program, and equipment and critical part inventories.
The Operation and Maintenance (O&M) Program is essential to fulfill the city’s duty to serve the residents and businesses of the City of Roseville. It is also the most significant part of the city’s effort to eliminate the occurrence of SSOs and stay compliant with the general order.
The city’s O&M program is comprised of these elements:
1. Collection System Mapping
2. Preventive Maintenance
3. Rehabilitation and Replacement
4. Staff Training and Certification
5. Equipment And Replacement Parts Inventories, Including Critical Replacement Parts
4.1 Collection System Maps and Information
The WWC Division maintains an up-to-date electronic map of the wastewater collection system as required by Section D.13(iv)(a) of the Order. The City uses ESRI GIS software to map all utilityrelated data. The GIS map platform, referred to as Roseville GeoViewer, shows all gravity main segments with the direction of flow, manhole information, pumping facilities, pressure pipes, and valves. In addition, the GeoViewer allows users to turn on/off different layers and base maps to display the information they need. Additional map layers available in GeoViewer include:
• Hot Spot Locations
• CIPP Lined Mainline Segments
• Food Service Establishments and Grease Removal Devices • Waterways
• Roadways
• City Boundaries
• Stormwater System
Table 4-1 shows the GIS map system, and how it incorporates each of the sewer shed basins within the City of Roseville’s jurisdictional boundaries.
33 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
4.1.1 Map Update Policy
This policy aims to provide uniformity in identifying, verifying, documenting, and tracking the changes to the sewer mapping system. In addition, this document will describe the process in which the mapping system shall be updated.
A significant effort is placed upon maintaining a very complete, accurate, and up-to-date wastewater collection map which is an essential component for the proper operation and maintenance of a wastewater collection system. Maps are updated as new sub-divisions are accepted or when field crews repair, rehabilitate or replace components of the system that require updating the maps. A mapping update policy has been developed to address procedures that ensure mapping updates or revisions are correct and completed in GIS.
CCTV crews identify discrepancies between existing system maps and real time field data. The operator shall note the discrepancies and submit changes to the WWC Supervisor when differences are identified.
Construction and Maintenance crews identify any new infrastructure added to the system.
Information required for CMMS Map Change will be directed to the WWC Supervisor. The information required for Mains, Laterals, and SMH’s are:
• Mains - Grid map area, the distance between SMH’s and pipe size, pipe material • Laterals –Grid map area, C/O location, length, depth, pipe size, material, and depth.
Table 4-1 Wastewater Grid Map
34 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
• SMH – Grid map area, depth, barrel diameter, access cover size and material, number of and pipe size of inlets and outlets, barrel lining/coating, drops Y/N.
The Supervisor will create a work order in Maximo listing the Classification as “Map Change.” Then select “Log” and “Add Row” to add a description of the asset that needs to be added/changed. In the Log section of the work order, the Supervisor will list all the details gathered from the field and attach a map if required. Do not change the status of the work order in Maximo CMMS.
The GIS group automatically receives all map change requests. Once all map changes are updated, the Supervisor will receive an email informing them of the completed work order, at which time the GIS group closes the work order.
4.2 Operation and Maintenance
The WWC Division’s O&M program focuses on eliminating sewer backups and overflows, increasing the lifespan of the infrastructure, and bringing uninterrupted service to the residents of Roseville. WWC division provides service to 146,875 customers. Within the 43.05 square miles of Roseville, the City inspects and maintains 17 lift stations, approximately 578 miles of sewer mains ranging from 6- to 84- inch diameter, and 293 miles of lower laterals. Table 4-2 below represents a few performance indicators the WWC division tracks and measures their performance against.

4.2.1 Preventative Maintenance Program
The WWC Division of the Environmental Utilities Department is responsible for the City's sewer system and implements preventative and corrective maintenance approaches to operate and maintain the system efficiently. The division's PM program involves cleaning sewers on a recurring schedule, including regular CCTV inspection to determine the efficiency of those PM activities. The GIS system divides the city into grids, enabling targeted PM scheduling for an individual grid based on history, CCTV inspection, and infrastructure's age. The WWC division schedules cleaning as often as every three months or up to ten years, with the age and condition of the pipe being key factors. The scheduled maintenance projects that are identified in Maximo are attached as Appendix 4-1.
35 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
Corrective maintenance projects and work orders are a concerted effort utilizing the PM and CCTV inspection programs. Information gathered during routine cleaning, repair work and inspection, generates the development of repair and replacement work orders. The following paragraphs describe the City's current operation and maintenance procedures for maintaining the wastewater collection system.
4.2.1.1 PM Cleaning Program
The WWC Division is equipped with three combination sewer cleaners to keep the sewer system operating efficiently and minimize line stoppages and calls for service. Sewer cleaning using hydraulic or mechanical methods performed on a routine basis helps remove accumulated debris in the pipe such as sand, silt, grease, roots, and rocks. Scheduled maintenance projects have been developed for each map grid based on historical data and field crew input.
4.2.1.2 Hot Spot Cleaning
In addition to scheduled maintenance, the WWC division aggressively cleans identified problem areas, known as hot spots. This list of hot spots has been compiled based on historical data, field crew observations, and CCTV condition assessments. These mainline segments tend to have more frequent backups due to sluggish flows, poor grade, and sags, The frequency of Hot Spot cleaning ranges from 1-6 months, depending on history and CCTV inspection data. The WWC division strives to reduce and eliminate these hot spot areas during CIP projects or rehabilitation projects performed by City crews. Currently, the WWC division has 276 segments identified as Hot Spots.
4.2.1.3 Electroscan Inspection
To identify and quantify locations of I&I entering the sewer system, the WWC division invested in Electroscan Technology, adding the equipment to a newer CCTV inspection truck. Using Electroscan, a probe is pulled through the mainline, and electricity is measured and used to identify any defect where the pipe may leak. This enables crews to pinpoint CCTV inspection of the pipe section before scheduling repair work to correct the deficiency. Electroscan has also proved valuable as a QA/QC tool for accepting Cured-In Place-Pipe rehabilitation projects. The city performed pre-post Electroscan inspections on sewer mains rehabilitated with CIPP technology. This pilot study proved the effectiveness of the Electroscan Technology in locating defects CCTV inspection didn’t identify.
4.2.1.4 CCTV Inspection Program
The WWC Division operates three CCTV vans to inspect the wastewater collection system. CCTV operators utilize NASSCO’s PACP coding format when inspecting sewer mains and laterals. All observations are coded and captured in the Granite Net Software system and are archived in a database for access. CCTV inspection crews also perform continual condition assessment inspections on existing infrastructure. For example, CCTV crews inspect mainline segments and lower laterals, looking for deficiencies to minimize problems within the collection system. In addition, sewer inspections identify unwanted connections and sources of I&I into the wastewater system. Finally, CCTV crews inspect new subdivisions or commercial projects before being accepted into the city and the time of warranty acceptance. These inspections are crucial to receiving infrastructure installed to City design and construction standards. Table 4-3 includes a sample CCTV report from GraniteNet inspection software. .
36 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
Table 4-3 CCTV Inspection Report
37 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
4.2.1.5 Root Control Program
The WWC Division has an effective chemical root control program, using Vaporooter products to limit or eliminate root growth in the City-owned portion of the lower lateral. In addition, the WWC division has two qualified applicators licenses (QAL) that allow the division to chemically treat laterals for a more effective root control program rather than contracting out for this service.
This program has dramatically reduced the division's exposure to back injuries resulting from loading and unloading a gas-powered eel from the truck each time. It also lessens the element of crush injuries and trip and fall hazards from eel rods across the ground. In addition, chemical root control has successfully reduced the maintenance time per lateral, which is evident in the reduction of lower lateral backups and overflows.
4.2.1.6 Lift Station Inspection and Maintenance
The city currently has 17 neighborhood lift stations throughout its service area. All 17 stations are equipped with a duplex or triplex pumping system, with the lead/lag pump cycled based on pumping hours. Power outages happen very infrequently. However, all new lift stations and four of the currently active seventeen lift stations are equipped with a 4-hour emergency overflow storage basin. WWC crews inspect the stations monthly, cycle pumps through a pull-down sequence, test floats for operation, and record the condition and any deficiencies at the station. In addition, all Lift Stations are equipped with a SCADA system, which the WWTP operators monitor 24 hours per day. Besides inspections, City crews perform wet-well cleaning and de-ragging of pumps every six months to eliminate pump failures and potential odor complaints.
4.2.2 Corrective Maintenance Program
WWC construction crews perform all repair work to the existing infrastructure. Work orders and projects are developed from information found during maintenance activities, inspections based on calls for service and condition assessment inspection findings. The Corrective Maintenance programs are defined below.
4.2.3 Infrastructure Repair
The WWC Division performs routine, emergency, and complex repairs, and replacements to its existing infrastructure. This work includes sewer main installation and repair, sewer manhole installation, and lateral repair and replacements. As a result, city crews have undertaken large projects, installing new mainline segments that have eliminated hot spots, replaced aging infrastructure, and upsized mains to provide additional system capacity. In addition, the WWC Construction crew has performed contractor caliber work at the City’s Regional Wastewater Treatment Plant at significant cost savings for the city. 38 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
4.2.3.1 Infill Projects
Depending on their schedule and workload, the WWC division construction crew holds the first choice for any proposed connection to existing infrastructure. If city crews are busy, contractors will be allowed to perform the work under the direction of a city inspector. However, if city crews complete the work, the contractor will schedule the work through the WWC Supervisor. City crews will complete the work on a time and material basis for the contractor.
4.2.3.2 CIPP Lateral Lining
The vast majority of the city’s SSOs have occurred in the lower lateral, caused by breaks in the VCP and root intrusion. As a result, the city invested in the trenchless technology Cured in Place Pipe (CIPP), purchasing an LMK lateral lining trailer. Lateral lining through an existing cleanout makes it possible to repair and reinstate the pipe integrity without disturbing landscape, sidewalks, roadways and with minimal disruption of service to the resident. CIPP essentially creates a pipe within a pipe and eliminates further root intrusion and sewer overflows. During condition assessment, lower laterals are CCTV inspected, and work orders are created for those identified as viable for CIPP lining. These work orders are then prioritized based on history and the number of calls for service.
4.2.3.3 Cleanout Installation Program
The WWC Division invests many resources in preventing backups that potentially become SSOs.
Since the City owns the lower portion of the lateral, access to the lateral through a cleanout is imperative in assessing its condition. The WWC division has identified the homes and businesses throughout the city with no cleanouts and created projects to install one at every service location.
One installed, the lower lateral is inspected and if necessary, additional work orders for maintenance or repair are created. Currently, the city installs over 100 cleanouts per year on this project.
4.3 Rehabilitation and Replacement
The City began its condition assessment of the collection system in 2006. At that time, the collection system was divided into 24 groups based on the age of the sewer main installation. The first group of pipes and manholes were inspected and included in the Rehabilitation and Replacement plan developed shortly after. To date, City crews have completed inspections in 14 of those 24 groups, which has led to the development of numerous CIPP and replacement projects.
Over the past fifteen years, experience has shown that identifying and prioritizing areas and sewer segments for assessment and rehabilitation is complex. It requires the availability of tremendous amounts of data, expertise in applying PACP coding, and professional judgment. During this time, the WWC Division has significantly advanced its knowledge of the collection system and its sewer assessment and rehabilitation approach. The City has recognized that CCTV inspection is the best method for identifying and prioritizing problematic areas. As such, the City continuously inspects pipelines and utilizes NASSCO’s PACP coding standard to develop a list of assets that need rehabilitation. When defects are identified, the City evaluates the risk of failure and assigns a priority ranking to each asset.
39 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
Prioritizing those assets relies on several factors, including:
• Severity and extent of the defects (PACP Score).
• Maintenance records and SSO occurrences
• Hydraulic capacity needs and projection.
• The estimated remaining useful life of the infrastructure This detail-oriented condition assessment approach enables the division to plan and design CIP projects to rehabilitate sewer infrastructure in a planned and organized manner. The supervisor will review the maintenance history of the main, any SSO history and determine if the segment should be rehabilitated or continue established preventative maintenance. The main will be added an asset group already created in Maximo CMMS if conditions warrant rehabilitation. Based on current condition, history of calls, and field crew observations, the assets are then prioritized for rehabilitation.
Once the asset group is established, the WWC Superintendent will meet with EU Engineering to review the data and create a CIP project for the upcoming fiscal year, based on priorities and estimated cost. This process ensures the projects will be completed timely, reducing the potential occurrence of an SSO.
In addition to condition assessment, the WWC division schedules with Public Works to inspect wastewater infrastructure ahead of residential and arterial street paving projects. This process enables the WWC division to perform necessary system improvements before completing the overlay project. The City maintains a 5-year list of planned R&R CIP projects
4.4 Training and Certification
One challenge when defining a training program is an influx of new employees. Entry-level employees with no training are a potential safety liability in the wastewater field. Training for new hires is predominantly on-the-job training, with classroom and online training finishing the remaining required training. As soon as available, new employees are scheduled for Confined Space Entry, Traffic Control &Flagging, and Excavation and Trench Shoring training, the division’s most significant safety liabilities.
4.4.1 New Hires
On their first day, a new employee will be issued a task booklet, which defines the necessary skills and training for their position. The new hire and Supervisor will go through the book, discuss how the employee will receive training, and receive sign-off on the tasks. The booklet covers all areas involving the wastewater collection system and is an aid in developing qualified, knowledgeable, and capable employees. When the employee becomes proficient in a task, the SR Utility Maintenance Worker or the crew leader signs and dates the book, verifying they have observed the employee satisfactorily complete the task. The training defined in the task booklet is provided through various methods, mainly on-the-job training, and begins the first day on the job. Finally, at the end of the probationary period, new hires are put through a series of activities to demonstrate their proficiency in all skills learned.
40 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
4.4.2 Training and Tracking
Safety training constitutes a significant portion of the training received each year and tracking individual completion of training can be insurmountable. The WWC Division utilizes a computerbased software program, Safety Plus Web (SPW), to monitor and track each employee’s level of completion. Supervisors can query individual employee training records, or the entire division, to see which courses need completion. In addition, SPW provides Competency-Based Training (CBT), requiring the employee to take and pass a test at the end of the presentation, demonstrating their understanding of the training material. In addition, Standard Operating Procedures (SOPs) have been developed for all equipment and procedures within the division to train new employees and provide a refresher for veteran employees. These SOPs are reviewed annually during a safety meeting and revised should there be a process change. Therefore, SOP development and training is an ongoing process.
The WWC division holds weekly safety meetings where supervisors or subject matter experts present safety topics specific to the wastewater collection field. These meetings are interactive with the crews and presenters and are great learning opportunities. In addition, the training course is added to SPW, so employees can fulfill the training online if they are absent. Finally, as new training requirements are developed, they are implemented into SPW to ensure all employees receive the required training throughout the year. Table 4-4 lists the required training specific for the WWC division.

4.4.3 Certification
The CWEA Technical Certification Program provides certification in various wastewater disciplines to promote the knowledge and skills of wastewater professionals. The City requires employees to take and pass the Collection System Operator Grade I test to be eligible for promotion to the Journey Level. The test for the required CWEA certification ensures that employees who hold this certification possess the knowledge, skills, and abilities to perform the collection system operator duties skillfully. In addition, to renew the certificate, the employee must complete 12 hours of continuing education training every two years.
Information on CWEA certification can be found at http://www.cwea.org/

5 Design and Performance Provisions
D.13.(v) Design and construction standards and specifications for the installation of new sanitary sewer systems, pump stations and other appurtenances; and for the rehabilitation and repair of existing sanitary sewer systems; and (b) Procedures and standards for inspecting and testing the installation of new sewers, pumps, and other appurtenances and for rehabilitation and repair projects.
5.1 Sanitary Sewer Design Standards
The purpose of the City Design Standards is to provide direction in the application of improvements that are to be dedicated to the public and accepted by the City for maintenance or operation and to provide for joint development of those facilities to be used by and for the protection of the public. This includes certain private works and improvements to be installed within existing City rights-of-way and easements. Whereas these Standards intend to govern all new construction, City staff shall interpret and apply the Standards in a manner that achieves their intent while encouraging and enabling the redevelopment of infill and vacant parcels, especially within the City’s Redevelopment Project Area. These Standards shall apply to, regulate, and guide the preparation of traffic impact studies and the design and preparation of plans for construction of streets, highways, alleys, drainage, sewerage, traffic signals, site access, water supply facilities and related public improvements, and shall set guidelines for all private works which involve drainage, grading, trees, and related improvements. The City’s sewer Design Standards are located on the City’s website at
https://p1cdn4static.civiclive.com/UserFiles/Servers/Server_7964838/File/Government/Departments/Develop ment Services/Engineering/Design and Construction Standards/2020 DS Sections/DS - SECTION 9 - Jan.2020.pdf.
5.2 Sanitary Sewer Construction Standards
The purpose of the City Construction Standards is to provide minimum standards to be applied to improvements which are to be dedicated to the public and accepted by the city for maintenance or operation and certain private works, as well as improvements to be installed within existing rightsof-way and easements. This is necessary to provide for coordinated development of required facilities to be used by and for the protection of the public. These Construction Standards shall apply to, regulate, and guide construction of streets, highways, alleys, drainage, sewerage, traffic signals, site access, water supply facilities and related public improvements, and shall set guidelines for all private works which involve drainage, grading, trees and related improvements.
The City’s sewer Construction Standards are located on the City’s website at https://p1cdn4static.civiclive.com/UserFiles/Servers/Server_7964838/File/Government/Departments/Develop ment Services/Engineering/Design and Construction Standards/2020 CS Sections/CS - SECTION 91 - Jan.2020.pdf
46 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
All improvements within the City rights-of-way shall be installed in accordance with the approved improvement plans and specifications, the City of Roseville Design Standards, the City of Roseville Construction Standards, and the State of California Department of Transportation Standard Specifications.
5.3 Sewer System Construction and Performance Testing
Section 91-12 of the City’s Sanitary Sewer Construction standards defines the criteria for testing of installed sewer improvements. Sewer mains, services, manholes and appurtenances shall be tested by the following procedures.
5.3.1 Testing Of Installed Improvements
A. Sewer Mains and Services – Public and private sewer mains and services shall be air-tested per ASTM C828 by the Contractor and the Environmental Utilities Department shall provide closed circuit TV inspection, after installation of the joint trench utility crossings and subgrade elevations have been met. Additionally, pipeline segments beneath road bases to be lime- treated shall be tested before and after the lime treatment process.
B. Air Pressure Test – Sewer mains and laterals shall be pressure tested in accordance with the National Clay Pipe Institute recommended guidelines with the following amendment:
1. The minimum test time shall be 60 seconds. The section of a sewer being tested must be pressurized to 3.5 psi, and during the test time must hold 2.5 psi or greater, or the section has failed.
2. For mains installed in an area where the water table is higher than the pipe, the test pressure shall be increased 0.5 PSI per foot of water over the pipe.
3. The test gauge shall be liquid-filled, capable of testing up to 15 PSI, and graduated to 1/10 PSI.
C. TV Inspection – TV inspection of sewer mains and services shall be performed by the Environmental Utilities Department, Wastewater Division. Costs for said inspection shall be borne by the Contractor. Preliminary inspections may be performed by outside contractors but shall not be accepted by the Environmental Utilities Department as an official record.
1. The sewer system shall be completely cleaned by an approved method prior to TV inspection. The sewer system shall be rejected if any of the following conditions exist:
a. For main lines 12 inches and smaller - standing water or sags greater than 1⁄2 inch in depth at acceptance or greater than 1 inch at warranty. b. For main lines exceeding 12 inches - standing water or sags greater than 3⁄4 of an inch in depth at acceptance and greater than 1 1⁄2 inches at warranty. c. Standing water in services.
d. Offset joints.
e. Joint separations greater than 1⁄2 inch wide.
f. Damaged pipe.
D. Inspection Criteria for Coated Ductile Iron Pipe – All ductile iron sewer will have the following additional inspection requirements:
47 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
1. The condition of the barrel section of pipe as well as 360◦ at each joint shall be recorded to a DVD or portable drive. Once completed, and the inspection demonstrates the pipe meets the City’s construction standards, the contractor may proceed with the backfill of the trench. The Contractor shall provide the DVD and a map of the section inspected, to the Wastewater Collection Division for review prior to the City’s acceptance inspection.
2. Upon finding any deficiency in the pipe which does not meet the design and construction standards of the City of Roseville, it is strongly encouraged that the contractor makes the necessary corrections at that time. If deficiencies aren’t corrected City forces at time of acceptance CCTV will identify these deficiencies and require the contractor to dig and replace the pipe sections; there will be no exceptions.
3. The observation data on the DVD provided to the City shall include the following:
a. City wide job number.
b. Encroachment permit number.
c. Project name.
d. Location (street name)
e. Manhole numbers (based on approved plan set or city asset numbers if applicable). f. Direction of inspection (upstream or downstream).
g. Date of inspection.
4. The speed of travel shall be slow enough to inspect each pipe joint, wye connection, coating integrity, and potential sags. Camera speed should travel at a rate of no more than 30 feet per minute. The camera speed shall be steady and slow enough to record features and defects.
E. Manholes – Sewer manholes shall pass a vacuum test consisting of the following criteria and procedures:
1. The test shall be performed after assembly of the manhole and installation of the pipe entering or exiting the manhole, but prior to backfilling. The Contractor shall perform the test and supply all test equipment. The Development Services Inspector shall witness the test results.
2. Lift holes shall be filled with non-shrink grout prior to testing.
3. Pipe entering and exiting the manhole shall be plugged. The plug shall be places on the flex joint outside of the manhole base. Securely brace the plugs to prevent them from being drawn into the manhole. Unused channels shall be permanently plugged with a plastic or clay stopper.
4. A vacuum of 10 inches of mercury shall be drawn to start the test. The amount of time required for the vacuum to drop to 9 inches shall be measured. The manhole will pass the test if the amount of elapsed time is greater than 60 seconds for a 48-inch manhole, 75 seconds for a 60-inch manhole, 90 seconds for a 72-inch manhole and 120 seconds for an 84- inch manhole. A liquid-filled vacuum gauge shall be used for testing. All detectable leaks shall be repaired with non- shrink grout while the vacuum is drawn. No mortar shall be applied to the inside of the manhole until the vacuum test has passed.
5. If the manhole fails the initial test, necessary repairs shall be made with a non-shrink grout while the vacuum is still being drawn. Retesting shall proceed until elapsed times are satisfactory.
48 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
6. After passing the vacuum test, all joints shall then be mortared, inside and out. Outside mortared joints shall be allowed to dry 24 hours or as approved by the Development Services Inspector before backfilling.
7. If damage to the manhole is evident any time during the construction, the Development Services Inspector may require repairs to be made on the manhole which will require a new vacuum test prior to acceptance.
8. Topside Improvements – When all water, recycled water and sewer infrastructures have passed air, vacuum, pressure, and continuity test as well as CCTV inspection the Development Services Inspector will email a notification to internal departments indicating that the project is ready for road bases and top side improvements only. This does not constitute approval for use of the infrastructure.
9. Tying Into the City System – A tie-in procedure shall be submitted and approved by the Environmental Utilities Department prior to the proposed work. The contractor shall allow for up to 7 days for review of the procedures by the Environmental Utilities Department.
The sewer system shall be tied into the City system within 10 working days upon completing and passing all the testing procedures. Tie-ins shall be conducted as specified in Section 91- 2 of the Construction Standards.
5.3.2 Punchlist Process
After the sewer manholes have been raised and finished to grade, the sewer system shall have a final ball and flush in the presence of the Development Services Inspector. The system shall then have a final TV inspection to ensure the entire sewer system is intact for warranty. Final ball and flush can be done by city forces on a time and material basis at the request of the contractor.
When all improvements are complete, the contractor shall provide a written request for a punch list inspection of the improvements. With the assistance and presence of the Contractor, the wastewater facilities punch list shall be generated by the Development Services Inspector and Wastewater Collection Division.
5.3.3 Repairing Installed Improvements
Sewer mains, services, manholes and appurtenances shall be repaired per these Construction Standards and by the following procedures.
A. Repairing Vitrified Clay Pipe
1. Damaged pipe shall be exposed and replaced in-kind by “bridging” the new pipe into place. Coupling devices shall not be used.
2. Sagging or misaligned pipe shall be exposed and corrected in place if possible. If the pipe is defective, then a new pipe shall be bridged in place.
3. After the correction has been completed, the excavation shall be backfilled and compacted to grade as specified. The repairs shall then be retested per section 91-12 of these Construction Standards.

6 Overflow Emergency Response
D.13. (viii) The enrollee shall develop and implement an overflow emergency response plan that identifies measures to protect public health and the environment. The plan must include (a) proper notification procedures so primary responders and regulatory agencies are informed in a timely manner, (b) a program that ensures an appropriate response to all overflows, (c)procedures to ensure prompt notification to regulatory agencies or other potentially affected entities of all SSOs that potentially affect waters of the State. All SSOs shall be reported in accordance with the MRP and WDR requirements, (d)procedures to ensure appropriate staff and contractor training on the ERP,(e)procedures to address emergency operations, such as traffic and crowd control,(f) a program to ensure all reasonable steps were taken to contain and prevent discharge of sewer to waters of the United States, and to minimize and correct any adverse impact on the environment from the SSO.
6.1 Notification Procedures
The WWC division maintains an Overflow Emergency Response Plan that covers the wastewater system and Lift Station response and procedures. Table 6-1 summarizes the response procedures.
Table 6-1 SSOERP Flowchart
51 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
The WWC division strives to operate, manage, and maintain all parts of the sanitary sewer system to prevent SSOs and mitigate the impacts quickly and efficiently should an SSO occur. The On-Call emergency vehicle contains a three-ring binder that includes the division’s SSO emergency response manual, the response plan, chain of communication, and notification procedures. In addition, the truck is equipped with the necessary tools and equipment to control and contain overflows and clear lower lateral blockages. The truck is outfitted with pneumatic plugs, rubber berms, and dry sweep, all of which are effective means of containment. Table 6-2 summarizes the division’s notification procedures.

6.2 Emergency Response Procedures
City of Roseville Wastewater Collection has developed the following procedures for responding to Sanitary Sewer Overflows (SSOs). The purpose of these procedures is to ensure that all SSO responses are conducted efficiently and effectively, meeting all regulatory requirements of the general order.
6.2.1 Goals of SSOERP
The purpose of this SSOERP is to ensure that the City of Roseville Wastewater Collection personnel follow established guidelines in cleaning up and decontaminating SSO’s which have occurred within the City’s collection system service area. The goals with respect to responding to SSO’s are:
A. Respond quickly to minimize the extent of the SSO;
B. Eliminate the cause of the SSO;
C. Contain the spilled wastewater to the extent feasible.
D. Eliminate public contact with the SSO;
E. Mitigate the impact of the SSO; and
F. Meet the RWQCB Monitoring and Reporting requirements
6.2.2 Investigate and Assess Problem (WWC Personnel)
Assessment starts with the phone call from the customer. Advise customer to stop all use of water in the home or business. Obtain as much information from customer as possible. Relevant information includes:
• Description of problem
• Specific location (e.g. manhole in street, front or back of property, cleanout box)
• Time the possible SSO was noticed
• Any other observations from the caller (e.g. odor, duration of spill, currently spilling)
o If you believe an active spill is occurring, mobilize a hydro-vac prior to arriving to access the call.
The City staff person that arrives first to the scene, is considered the First Responder. Upon responding, city staff member performs a quick assessment of the overflow to determine the extent of the overflow.
The First Responder is responsible for the following:
• Requesting additional wastewater crews or other personnel as needed • Notification of Superintendent/Supervisor in the event of Category 1 or 2 SSOs
53 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
• All field documentation including pictures of the SSO and final field spill report.
• Protection of the health and safety of the public by preventing contact with the SSO
The first responder shall:
A. Locate SSO by address, cross street and point of overflow (i.e. manhole, cleanout, pump station, broken pipe). Note time call was received, as well as time of arrival. See Appendix A for documenting start time of SSO.
B. Determine the current magnitude of the SSO
1. Flooded Structure? - See Appendix B
2. Storm water inlet or drainage way
3. Potential for public exposure
4. Related problems
i. Is overflow related to a street collapse?
ii. Is overflow related to construction work?
iii. Is overflow causing a traffic hazard such as displaced manhole cover or street flooding?
5. Provide initial estimate of overflow rate using pictures and tables (see tab 6 for spill estimation)
6. If SSO is a category 1 or 2 spill, notify WWC Supervisor or Superintendent as soon as possible, then refer to Sec. II and start containment
7. If SSO is category 3 spill, refer to Sec II, and start containment
8. Spill categories are defined below:
i. Category 1 – spill is defined as any amount of wastewater resulting from a failure or flow condition that reaches surface water or a drainage tributary to surface water.
ii. Category 2 –defined as discharges of wastewater of 1,000 gallons or greater, resulting from a failure or flow condition that do not reach surface water or a drainage channel or storm system unless the entire SSO discharged has been fully captured and disposed of properly iii. Category 3 – spill is defined as all other discharges of wastewater resulting from a failure or flow condition in the enrollee’s system. 54 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
NOTE: Superintendent or his designee will handle all notification to regulatory agencies regarding the reportable SSO.
C. If SSO reaches surface water or drainage channel tributary to surface water, and is 50,000 gallons or greater, sample receiving water to obtain baseline data. Refer to Appendix C for sampling information.
6.2.3 Contain SSO (WWC Personnel)
The overflow must be contained. Containment becomes more difficult if the overflow reaches the storm drain system or drainage way, 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 point.
A. Options for containing overflow
1. Containment berm at catch basin or drain inlet
2. Rubber mats and sandbags at catch basin or drain inlet
3. Sandbags in gutter
4. Dig trench in ground
5. Dry sweep
6. Vactor
B. Overflow in building
1. If necessary, evacuate affected people
2. Advise customer to keep family members and pets out of contaminated areas, and not to track contamination throughout non-affected areas.
3. Notify Risk Management at 774-5420 or 774-5202 during business hours. After hours, of if no answer, contact Dave Rawe at 209-613-9448.
4. If adjuster or Risk Management can’t be reached, contact one of the approved restoration companies starting with:
i. Restoration Management Co. 800-400-5058
ii. Serv-Pro 916-632-2250
5. If Restoration Company arrives before the adjuster, authorize only emergency cleaning services only. Hand resident our camera and request them take pictures of affected area. Do not enter house.
55 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
6. If property owner declines cleaning services, request they sign and date the Declination of Clean Up Services Form.
C. Overflow into storm drain/drainage ditch
1. Trace overflow in storm drainage system to downstream end point.
2. Plug all affected storm drain outfalls or block the creek and channels to contain spill.
3. Turn off storm water pump station if available
4. Hydro mains and vacuum all water from storm drain basin and system.
D.If SSO is a Category 1 spill, post warning signs around containment area and follow directions from RWQCB Staff (Region 5) or Fish and Wildlife Staff.
E. Example equipment for containing overflows.
1. Overflow onto ground or into building structure.
i. Containment berm
ii. Sand bags
iii. Plastic sheets
iv. Dry sweep
v. Vactor
2. Overflow into a storm drain/drainage way
i. Pneumatic plugs
ii. Bypass pump
iii. Vactor
iv. Sandbags
3. Overflow at lift station
i. Vactor
ii. Bypass pump
iii. Emergency generator
4. Warning signs to post around contaminated area.
5. Begin preliminary notifications – Refer to SSO notification guide
6.2.4 Traffic Control (WWC Personnel)
Traffic control may be needed immediately to protect the health and safety of the public and/or maintenance staff. Typically, immediate traffic control is needed if 56 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
there is a street collapse or significant depression in the pavement that is related to the sewer, if the manhole cover is ajar, or if the overflow causes flooding of the street. Traffic control may be needed to prevent wastewater from being further dispersed and to protect the maintenance crew while containing the overflow and removing the blockage.
A. Provide traffic control per Cal Trans Work Area Traffic Control Handbook (WATCH)
B. If necessary, use other departments (i.e. Police/Fire, Public Works) to ensure proper traffic control.
C. Control public contact with the SSO by isolating the area with barricades, signs or traffic cones.
6.2.5 Correct Cause (WWC Personnel)
The cause of the overflow may be located a considerable distance downstream of the SSO in areas with flat terrain. During large storms, overflows can be caused by excessive I&I in the collection system. I&I can greatly increase the flow in a collection system and cause overflows from pipes that are only partially blocked.
I&I can also directly affect the hydraulic capacity of mainlines and lift stations.
Under these conditions, it may not be possible to stop the overflow, until the flows recede.
A. Locate cause of overflow
1. Sewer main
i. Check flow in manholes
ii. Blockage should be between a manhole with sluggish flow or surcharging and a manhole with very little flow or is dry.
2. Sewer service
i. Check flow in city cleanout. If cleanout is dry, and resident is still plugged, stoppage is located on private property, and is not the city’s responsibility.
ii. If no city cleanout exists, but the resident has a 4” private cleanout, run this private cleanout to clear the blockage. Once cleared, CCTV to determine the location of problem (Refer to Appendix D, Sec 6)
iii. If no city or private cleanout can be located, check mains, both upstream and downstream. If the main is running clear, notify 57 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
the resident the problem is on their side, and explain city cleanout policy
iv. If service line is on a dead end run, regardless if the cleanout is clear, clean the mainline segment with Vactor.
3. Lift Station
i. Check alarm status inside control panel for indication of problem.
ii. If power is present, but pumps aren’t operating, switch control to hand.
iii. If pumps operate in hand, refer to Lift Station Failure Procedure (Tab 10).
iv. If no power is present, contact Roseville Electric, determine remaining level in station, and contact Collection Personnel for assistance. Refer to Lift Station Failure Procedure (Tab 10) B. Clear Blockage
1. Sewer Main
i. Clear mainline blockage using Vactor from dry manhole. ii. Determine possible cause of blockage and note on Field Spill Report Form.
iii. Refer to SOP WWC-002 For Vactor
2. Service Line
i. Clear blockage using Gas powered EEL or Model C Electric Eel.
Refer to SOPs WWC-007 and 020
ii. Call additional personnel is assistance is needed.
3. If blockage cannot be cleared
i. Increase containment and initiate bypass pumping
ii. Perform CCTV inspection to determine potential problem iii. Dig and repair sewer line at blockage location
C. Lift Station
1. If no power is present :
i. Contact Roseville Electric to verify outage and time estimation of power being restored.
ii. Determine the wet well level and remaining downtime left at the station.
58 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
iii. If downtime exceeds the max allowable retention, contact collection system personnel, and request Vactor support. iv. If power outage is extensive, contact additional personnel for 2nd Vactor support.
v. Continue vacuuming wet well until power is restored, and lift station is running in auto.
2. If power is present, but pumps aren’t operating:
i. Attempt to operate pumps in “hand” position. If pumps do operate in “hand”, contact on call electrician, and continue to operate and monitor levels in the wet well.
3. If SSO is caused from force main failure, all power to lift station panel will be controlled using identified energy control procedures (ECP).
Wet well levels will continue to be monitored using Vactors or bypass pumping, until repairs can be made to force main.
4. If portable generation is needed at lift station, on call electrician needs to be present for the connection. All panels have external plugs and disconnects for portable generation connection. Each lift station location has a specific pre-made cable for generator connection.
6.2.6 Final Volume Estimate (WWC Personnel)
The final overflow volume is estimated to determine if additional reporting to regulatory agencies is required and for the City of Roseville’s records when reporting to CIWQS. A minimum of five (5) pictures are required for every spill response, and locations are noted on the field spill report. Place an object in the photo for contrast. The following methods are approved for determining the gallons spilled during an overflow event.
Eyeball Estimation- Estimate the overflow rate out of a clean out by estimating the time needed to fill up a known volume, such as a five-gallon bucket. Imagine the amount of water that would spill from this bucket. This method is useful on spills that occur on hard surfaces such as concrete or asphalt Measured Volume- The volume of most small spills that have been contained can be estimated using this method. The shape, dimensions and depth of the contained wastewater are needed. This information is used to calculate area and volume of the spills.
59 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
1. Determine the shape of the spill
2. Measure or pace off the dimensions. Measure the depth at several locations and calculate the average. Convert all dimensions to feet.
3. To calculate the area square footage, use the following:
a. Rectangle: Length (ft.) x Width (ft.)
b. Triangle: Height (ft.) x Base (ft.) x .5
c. Circle: Diameter (ft.) x Diameter (ft.) x .785
d. Multiply the area (sq. ft.) by the depth (feet), to get the volume in cubic feet. Multiply your volume by 7.48 to convert to gallons.
Not all SSO’s will conform to the shapes above. If this occurs, break the area up as much as possible into known shapes and calculate the volume in each.
Calculating large volume spills is challenging because the area and depth are difficult to measure, and chances are these spills are not fully contained. Several methods are available to determine the volume.
Flow Estimation Chart- The table below (Section 5 of the SSOERP binder) presents pictures with varying flowrates of sewage overflowing from a manhole. Estimate the overflow rate by comparing the overflowing manhole with the pictures shown below.

60 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
Flow Rate and Duration- Overflow volume can be estimated by multiplying the overflow duration by the overflow rate. The overflow rate can be determined by pick hole or vent hole spill height (section 5, SSOERP binder), flow meter data, SCADA information and pump data from lift stations.
The overflow volume can be estimated with the following formula:
Volume (gal)= estimated flow rate (gpm) x duration of overflow (minutes) 61 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
The charts below represent measurement point and flow rates based off height of water column measured
Estimated Flow EDU Chart- This method can be used for overflows from residential properties when enough information has been gathered through interviewing the resident.
Be clear with your questions and explanation for the interview. Only interview residents from the household contributing to the SSO. The table below is based off our design criteria of 190 gpd. and is included on the Field Spill report. It is a quick way to estimate volume from small overflows.

2. Private residential spills, crew will provide a work order request to Supervisor documenting hours worked, equipment used and actions taken.
6.3 Staff and Contractor Training
To train WWC Employees on the importance of the SSOERP, Supervisors created a Powerpoint Presentation as a training resource. The interactive presentation covers the written SSOERP in a classroom setting. This setting allows employees to clarify any elements within the procedure. The annual training is followed by a competency test and classroom spill simulation. In addition, WWC employees built a spill simulator in the training yard at the DCWWTP to test employees’ skills in estimating spills. If desired, supervisors can create spills from either a manhole, cleanout, or both. The water is metered and creates an accurate simulation within the confines of the WWTP.
Contractors are provided with the City’s wastewater collection system policies and procedures.
Per the contract, they are required to train all their employees on the City’s wastewater collection system policies and procedures before performing work on the City’s wastewater collection and conveyance system.
65 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
6.4 Spill Mitigation and Containment
The WWC Division has written the attached SOP for spill mitigation and containment. The plan is described throughout the SSOERP and in the Table 6-1 flowchart. Whenever a Sanitary Sewer Overflow (SSO) occurs, the highest priority is to contain the overflow and minimize the exposure to the public or the environment. This procedure will address the specific processes available to contain an SSO. Containment of an SSO becomes more difficult once the overflow reaches storm drain systems or a waterway. The quicker the source and the extent of the overflow can be identified, contained, or controlled, reduces the SSO's impact exponentially. Following the Sewer System Management Plan (SSMP) goals, quick response and containment will protect public health and safety while minimizing the environment's negative impacts.
The assessed hazards that may exist when responding to an SSO are:
• Traffic control
• Bloodborne pathogens
• Slips, trips, and falls
• Atmospheric conditions
• Pneumatic plugs
• Sprains and back injuries
Upon arrival to the location, survey the scene to determine the potential overflow location and source. There are times when called for a sewer overflow, and the source is potable water or storm drainage. Once determined, the water source is the sewer, mobilize the necessary wastewater collection personnel and equipment needed for assistance. Determine the category of the overflow, discharge points, and whether the SSO can reach Water of the State. Immediate notification to the Office of Emergency Services is required, should the overflow reach waters of the state. If the spill cannot be eliminated by controlling water flow from a residential or commercial building, more than likely, this spill is either a plugged main, structural deficiency, or an inoperable lift station.
The area impacted by the spill and the potential work area shall be secured to divert vehicle traffic and pedestrians away from the area by using any combination of signs, cones, delineators, barricades, arrow boards, or caution tape. Multiple techniques are identified to contain the spill depending on the circumstances, spill category, and material available. In no order, the list below is possible containment options.
Containment
Situation Options for Containment
Curb and
Gutter
• Create berm with rubber berm, dry sweep, dirt, or
sandbags; Utilize natural low spots or grade deviations • Use hydro-vac to control overflow
66 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
Lift Station
Failure
• Use hydro-vac to contain
• Backup generator
• Bypass pumping
Open Space
• Dig a trench for containment
• Sandbag berm
• Dirt berm
Creek • Plug all affected storm drain inlets
Storm Drain
System (Dry)
• Plug all affected storm drain inlets; plug outfall if necessary
• Contain using the hydro-vac
• Request additional hydro-vac support if necessary
Storm Drain
System
(Storm Event)
• Plug all affected storm drain inlets
• Emergency bypass pumping
• Turn off stormwater pump station if applicable
Building
Evacuate residents if needed
Pop cleanout cap off; If no city cleanout, attempt to locate Pop private cleanout if available
Contain outside if overflow is relieved by
locating/removing cleanout cap
Containment with Hydro-Vac
Determine a location downstream of the spill appearance point where the hydro-vac unit can be set up and capture all water, including wash down water. Ensure no storm drain inlets are between the containment point you choose and the overflow point. Continue vacuuming overflow until the blockage has been cleared. Once cleared, wash remaining spill water to the vac tube to be vacuumed up.
Containment Using Berms and Mats
Utilize dirt, rubber berm, dry sweep, or other obstructing material to block drain inlets and pond the spill to a low natural area to contain and minimize the spill's effects. If possible, divert the spill to a downstream manhole that is not affected by the blockage.
Attempt containment by covering the affected storm drain inlet with rubber mats. Secure the mat in place with sandbags, dirt, or other heavy objects to keep in place.
Containment Using Pneumatic Plugs
Plugging the affected drain inlet or multiple drain inlets with a pneumatic plug can be effective. A pneumatic plug in the storm drain outfall would prevent the overflow from reaching the waterway. However, depending on the location within the City, drain inlets will vary in size, so utilizing plugs may not be the best option.
67 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
SSOERP- Appendix A- SSO Start Time Policy
Upon receiving call, note exact time that call received from answering service or administrative staff. This time will be used as a base for when the SSO started. Notify resident or business to stop using all water if possible.
A. Upon arrival, note if spill location point is or is not actively spilling. If not spilling from spill location point, but there is clear evidence of spill that requires a Vactor for cleanup effort, then document occurrence as a spill.
B. Initiate SSOERP to ensure that the SSO is contained, and the cause is corrected.
C. Photograph all affected areas, during the SSO, demonstrating containment and after cleanup. Use something in picture to gauge size of area features (i.e. tape measure, 5 gal bucket, etc) Email pictures to the Superintendent after completing necessary paperwork.
D. Provide detailed description of the SSO event, including exact times of arrival, SSO stop time, containment procedures, and names of collection personnel assisting you in the overflow.
E. The following questions should be asked of the resident or the individual reporting the potential SSO:
1. Did you notice water coming from the cleanout at the property line or manhole in the street? If so, what was the approximate time?
2. Were your drains running slowly at any time prior to you calling? If so, what was the approximate time?
3. If there were neighbors outside, close to the area of the SSO, did they notice water spilling? If so, what was the approximate time?
4. Be prepared to provide a brief summary of how you determined the start time, describing the steps you took while coming to your decision.
F. If the above questions do not produce an accurate account for the SSO start time, use the time the call was received by either the office personnel or the after-hours answering service, and subtract 15 minutes. Record this time as actual start time on the SSO Field Report Form.
G. If the evidence of the spill travels a farther distance than the logic of the 15 minutes, the field crew/responders shall try to recreate the spill the following day, using clean water.
H. In the event of an SSO from a sewer lift station, the start time will be determined using information gathered from the SCADA system.
I. SSO Stop time will be determined by either:
1. The arrival time of the service worker if the overflow had stopped prior to their arrival.
2. Clearing the blockage.
3. Interview of resident or witnesses
68 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
SSOERP Appendix B- Flooded Structure Pro cedures
In the event a failure in the City’s wastewater collection system causes a Sanitary Sewer Overflow in a resident’s home or business, instruct them to:
1. Keep people and pets away from the affected area(s), and do not track contamination throughout non-affected areas.
2. Don’t attempt to clean up the overflow. Instruct them the city has restoration companies available and will respond.
3. Turn off all central heat and air-conditioning systems and prevent flow from reaching any floor vents with towels or blankets.
4. Leave these items in the affected areas for restoration companies to cleanup.

SSOERP Appendix C- Water Quality Sampling
This water quality sampling procedure describes the process and the sampling methodology to be used in the event of a sanitary sewer overflow exceeding 50,000 gallons. The water quality sampling results will enable the division to prioritize areas of concern regarding water quality impacts. Surface water samples will be collected using a grab sample technique. Employees are required to wear new sterile powder free surgical gloves when collecting all samples.
Trigger for Sampling -Water quality sampling is required within 48 hours of initial SSO notification for Category 1 SSOs in which 50,000 gallons or greater are spilled to surface waters.
Safety and Access- Water quality sampling should only be performed if it is safe to do so, and access is not restricted or unsafe. Unsafe conditions include traffic, heavy rains, slippery or steep creek banks, visibility issues, high flowing creeks and limited access due to soil conditions or poor terrain.
Where to Sample1. Source of SSO - Determine the entry point (source) of the SSO into the creek, and move downstream approximately 10 feet downstream.
2. Upstream Sample – Sample at a point 100 feet upstream from the source.
3. Downstream Sample – Sample at a point 100 feet downstream from the source. Determine the water velocity present in the creek or body of water during the SSO. Dropping debris in the creek, and timing how long the debris takes to travel a known distance is a good indicator of the water velocity present. Use this information to determine the next downstream sampling point. Multiply the water velocity by the spill duration to figure the furthest point downstream to sample.
Sampling Procedure1. Put on required PPE (safety glasses and latex gloves)
2. Collect Upstream Sample - Move approximately 100 feet upstream of the source.
a. Label the bottle accordingly and take a picture of the location you are sampling.
b. Sample away from the bank and avoid any debris or scum layer from the surface.
c. Fill the bottle against the direction of flow, replace the cap and secure the sample to avoid contamination.
70 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
d. Use a thermometer to measure the temperature of the upstream sample location and record the results.
3. Collect Source Sample- Move approximately 10 feet downstream of the source location.
a. Label the bottle accordingly and take a picture of the location you are sampling.
b. Sample away from the bank and avoid any debris or scum layer from the surface.
c. Fill the bottle against the direction of flow, replace the cap and secure the sample to avoid contamination.
d. Use a thermometer to measure the temperature of the source sample location and record the results.
4. Collect Downstream Sample – Move approximately 100 feet downstream of the source.
a. Label this sample “Downstream 1” and take a picture of the location you are sampling.
b. Sample away from the bank and avoid any debris or scum layer from the surface.
c. Fill the bottle against the direction of flow, replace the cap and secure the sample to avoid contamination.
d. Use a thermometer to measure the temperature of the downstream sample 1, and record the results
5. Collect Downstream Final Sample - After using the velocity and distance to determine the furthest downstream sample point, move to that location. a. Label this sample “Downstream Final” and take a picture of the location you are sampling.
b. Sample away from the bank and avoid any debris or scum layer from the surface.
c. Fill the bottle against the direction of flow, replace the cap and secure the sample to avoid contamination.
d. Use a thermometer to measure the temperature of the sample, and record the results
Required Water Quality Analyses – As detailed in section C-5 of Monitoring and Reporting Program (MRP), Order WQ- 2013-0058, a Technical Report shall be submitted in CIWQS online database with 45 calendar days. All samples will be immediately transported to the nearest certified water quality laboratory for analysis (DCWWTP or PGWWTP labs). The sample analysis, at a minimum will include the following:
1. Ammonia
2. pH
3. Electrical Conductivity
71 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
4. Bacterial indicators, such as total and fecal coliform enterococcus and e-coli, per the regional Basin Plan or as directed by SWRCB
5. Temperature
Equipment and Supplies – The following items and PPE are required for sampling:
1. Cooler with Blue Ice
2. Sterile sampling bottles
3. Powder free latex gloves
4. Safety glasses
5. Marking pen
6. Field log forms
72 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
SSOERP -Appendix D- Sewer Call For Service
When dispatched to a home experiencing sewer problem, the following procedures should be adhered to provide the resident with the best possible customer service and quickly correct the problem causing the SSO.
Residential
1. Contact the homeowner or resident upon arrival. Explain the process you will use to determine the problem. Resident should have already been instructed to stop all water use, so if water is still spilling from cleanout, check the nearest upstream manhole on the mainline for a blockage.
2. If no cleanout is visible, look in CMMS for cleanout location, look for an “S” marked in the curb, or other information that might indicate a cleanout.
3. If a city cleanout is found, clear the lateral blockage using the eel and a root cutting head, do not use a hand tape. CCTV to ensure line is clear, and all blockages have been removed. Record all time and pertinent information you have found on a work order, service request, or for after-hours calls, your overtime tag.
4. If no cleanout is found, locate the closest downstream manhole, and call for Vactor assistance, and run the main.
5. If the residence does not have a city cleanout, and the above procedures did not alleviate the blockage, we will use our equipment to run a “Viable” cleanout that belongs to the resident. This “viable” cleanout should be a factory fitting 4” cleanout, either a wye or combo wye, that we can easily get our equipment into and service the line. Once the line has been cleared, we will CCTV through this same cleanout, and determine where the blockage was located.
6. If the blockage was located below the location a city cleanout should be installed, we will schedule a cleanout installation during normal business hours.
7. If the blockage is located within the customer’s service line, notify them that the problem is in their portion of the lateral, the location and severity of the problem.
Advise the resident of the City’s policy for cleanout installation, and let them know this is a one-time service, and the city will not clear future blockages from the homeowner’s cleanout.
Document all information in the CMMS under activity code- SPHCC, (Sewer Plug Homeowner City Cleared) on a service request.
Private Commercial
When dispatched to a commercial property experiencing an SSO, start containment of the spill immediately. Notify the manager to stop using water and to call a plumber. Make sure the manager understands City staff will be containing the spill until their plumber responds, and they will be billed for staff and equipment. If after 60 minutes, the plumber doesn’t show, notify Placer County Health Department. Notify your supervisor that the health department has been called and to discuss possibly clearing the main or service.
73 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
SSOERP Appendix E- Sewer Lift Station Failure Response
The purpose of this procedure is to define strategies necessary to prevent an SSO from a lift station, in the event of a power or component failure within a lift station. The City of Roseville operates and maintains 17 neighborhood lift stations. Each station is equipped with SCADA, monitored 24 hours per day by wastewater treatment plant personnel. Each station has the maximum allowable downtime posted inside the door of each control panel. This identifies the retention time and the storage capacity in the collection system assets, before an SSO will occur. The lowest identified manhole is also identified to assist on call personnel in determining the remaining downtime. In the event of a lift station failure, the plant operator will notify the answering service that an alarm has been activated at a station, and the on-call service worker will respond and assess the alarm.
If no power is present in the panel, the service worker will:
1. Contact Roseville Electric at 774-5620, to verify they are aware of the outage.
2. Determine the level, and remaining downtime left in the station.
3. If downtime will be more than the maximum allowable retention, the on call service worker will call collection system personnel off the standby list, to get a Vactor in route. The Vactor will decant water at an identified point in the system, which won’t affect the left station levels. If it appears that one Vactor won’t keep up with flows, the on call service worker will call in additional personnel with Vactor to maintain levels in the station.
4. If outage appears to be a lengthy process, contact supervisor. Portable generator may be needed. In this event, an electrician will be needed.
5. Once flows are maintained, contact Supervisor to make them aware of the situation.
If Power is present in station, but pumps are not operating, the service worker will:
1. Attempt to operate the pumps in “hand” mode to eliminate the possibility of an SSO
2. If the pump operates in “hand”, continue operating and monitor the levels in the wet well. Contact the On Call Electrician @916-532-0612 and continue to monitor.
3. If station will not operate in hand mode, call additional personnel in with Vactor to monitor wetwell levels. Vacuum and decant accordingly, until the problem is rectified.
4. If it appears that one Vactor won’t keep up with the amount of flow into the wet well, the service worker will call in a second Vactor to maintain the levels in the station.
5. Standby and assist on call electrician, until the station is operational. 74 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22

SSMP ELEMENT 7
7 FOG Control Program
D.13 (vii) Each enrollee shall evaluate its service area to determine whether a FOG control program is needed. If FOG is found to be a problem, the enrollee must prepare and implement a FOG source control program to reduce the amount of FOG discharged into the sanitary sewer system. The plan shall include (a) public education outreach that promotes disposal of FOG, (b) a plan for disposal of FOG generated within the sanitary sewer system, (c) the legal authority to prohibit discharges to the system and measures to prevent SSOs and blockages from FOG, (d) requirements to install GRD, design standards, maintenance and BMP requirements, and records and reporting requirements, (e) authority to inspect grease producing facilities, enforcement authorities and sufficient staff to inspect and enforce FOG ordinance,(f) identification of sewer sections subject to FOG blockages and pm schedules for each section,(g) develop and implement source control measures for all sources of FOG for each section identified in (f) above.
This chapter describes the City of Roseville's Fats Oils and Grease program, developed as Roseville Municipal Code Section 14.14, in 2008. The ordinance's purpose is to provide the maximum beneficial use of the City's sewer services and facilities while preventing blockages of caused by discharges of FOG into the sewer, specifically from food service establishments (FSEs).
The City relies on two major components to control or eliminate the amount of FOG entering the wastewater system, 1) cleaning and inspection of the collection system on a prescribed maintenance schedule and 2) inspection, enforcement, and education for FSEs. FOG ordinance can be found at: http://qcode.us/codes/roseville/view.php?topic=14-14_14&frames=on
7.1 Public Education Outreach
WWC and Industrial Waste Division personnel developed public outreach materials and handouts that are distributed to all food service facilities managers during the facility inspection. In addition, all FSEs are required by RMC Section 14.14 to apply for a FOG Discharge Permit. The permit application includes references to RMC 14.14, which provides Frequently Asked Questions, Maintenance and Pumping Requirements, and Best Management Practices (BMPs) for the managers to follow. Finally, the City’s website below offers links for available public outreach:
https://roseville.ca.us/government/departments/environmental_utilities/at_your_service/sewer/se wer_business_customers
7.2 FOG Disposal Plan
Food Service Establishments and FOG generators are responsible for hiring private service providers to pump and haul FOG from their grease removal device at scheduled intervals. The requirement of the permittee is to keep all records, manifests, receipts and invoices for the cleaning 77 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
and maintenance of the device, which includes final disposal location. These records shall be provided to any City of Roseville inspector or enforcement officer upon request. Although City does not endorse or recommend services provided by any one service provider, the City will provide a list of service providers that are commonly used by businesses in the area.
7.3 Legal Authority
The WWC Division of Environmental Utilities manages the FOG control program, issuance of permits and performs inspection of all FSEs within its service area. In addition, RMC Chapter 14.14 includes all legal authority necessary to prohibit discharges to the system and identify measures to prevent SSOs and blockages caused by FOG. All FSEs are required to provide wastewater that is acceptable to the city, before discharging to the public sewer. A summary of the legal authority is included in Table 7-1.
Table 7-1 FOG Legal Authority
RMC Chapter Number RMC Chapter Title
14.14.010 (A) General Provisions- Purpose
14.14.030 FOG-Waste Discharge Permit Required
14.14.040 FOG-Discharge Limitation
14.14.050 Public Sewer Overflow; Nuisance abatement
14.14.070(F) Prohibitions
14.14.190 FOG Discharge Permit Conditions
14.14.320 Harmful Discharge
14.14.360 Violation-Penalty
7.4 GRD, Design Standards, BMPs, Recordkeeping and Reporting
7.4.1 Requirement to Install GRD
Every FSE at the time of construction, remodel or change in operation is required to install and maintain an approved and adequately sized grease removal device. In addition, at the EU Directors' discretion, may require an FSE that has caused or contributed to a greaserelated blockage, install a grease removal device. Depending on the type of facility, certain FSEs may require a grease interceptor, grease trap(s), or may not require a grease removal device (GRD). If during the plan review process, an FSE enrollee does not believe that their operation needs the designated GRD, they can request a variance from the ordinance. The final determination of the variance request is at the sole discretion of the EU Director. 78 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
7.4.2 Design Standards
The City Design Standard section 9-10. (G) indicates grease removal device sizing and installation shall conform to the current edition of the California Uniform Plumbing Code.
Grease interceptors shall be constructed following the design approved by the director and shall have a minimum of two compartments with fittings designed for grease retention. A 24” access manhole shall be installed over each interceptor chamber. The frame and cover shall be watertight and set to finish grade, making inspection, sampling, and grease removal activities available. In addition, the grease interceptor shall be installed at a location where it shall always be easily accessible for inspection, cleaning, and removal of accumulated grease. The minimum size of a grease interceptor for a new FSE is 1,000 gallons.
7.4.3 Best Management Practices
Every FSE shall implement BMPs in its operations to minimize the discharge of FOG to the grease control device and/or the public sewer. Detailed requirements for BMPs shall be specified in the FOG WDP and all FSEs are required, at a minimum, to comply with the permit BMPs as well as any additional BMPs established by the director. BMPs may include, but are not limited to, kitchen practices and employee training procedures that are essential in minimizing FOG discharge to the public sewer. Additional BMP practices are available on the City’s website.
https://roseville.ca.us/government/departments/environmental_utilities/at_your_service/se wer/sewer_business_customers
7.4.4 Records and Reporting Requirements
The permittee shall be required to keep all manifests, receipts, and invoices of all cleaning, maintenance, grease removal of/from the grease control device, disposal carrier, and disposal site location for no less than three years. In addition, the permittee shall, upon request, make the manifests, receipts, and invoices available to the director, any inspector, or an enforcement officer. These records may include an on-site logbook of grease interceptor, grease trap or grease control device cleaning and maintenance practices, a description of BMPs being implemented, including employee training, and copies of records and manifest of waste hauling interceptor contents.
7.5 Authority to Inspect
RMC section 14.14.290 grants the Director, an inspector, or an enforcement officer access to all parts of a wastewater generating and disposal facilities for purposes of inspection and sampling during all times the FSE is open and operating. No person shall interfere, resist or refuse entrance to the Director, an inspector, or enforcement officer attempting to inspect the facility. Any violation of this chapter, or the orders, rules, regulations, and permits issued under this chapter, is unlawful and shall be an infraction or misdemeanor as determined by the city attorney 79 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
7.6 Hot Spot Identification and PM Schedule
The WWC Division’s CMMS maintains all records for maintenance, inspection, and construction work orders for the collection system. Sewer mains subject to blockages from FOG or mains that require higher cleaning frequency are added to the division’s Hot Spot List. These mainline segments tend to have more frequent backups due to sluggish flows, poor grades, and sags, which allow solids to settle and FOG to form. The hot spot list has been compiled based on historical data, field crew observations, and CCTV condition assessments. These mainlines are also identified in a GIS layer in the Roseville GeoViewer, so field crews can access them while performing maintenance in the field. The frequency of Hot Spot cleaning ranges from 1-6 months, depending on history and CCTV inspection data. The WWC division strives to reduce and eliminate these hot spot areas during CIP projects or rehabilitation projects performed by City crews. Mainline segments get added to the Hot Spot list based on conditions noted during CCTV inspection and the current frequency of cleaning. Currently, the WWC division has scheduled maintenance projects with 276 mainline segments identified as Hot Spots.
7.7 FOG Source Control Measures
One of the more significant additions to the WWC FOG program was the requirement of a FOG Waste Discharge Permit (WDP). Ordinances in the RMC require that before discharging any wastewater from an FSE into the wastewater system, the enrollee must obtain a WDP. The WWC division performs facility inspections before the FSE can discharge. The terms and condition of the WDP are as follows.
Grease interceptors/traps are required for food handling facilities unless the Environmental Utilities Director has issued a waiver or variance (RMC 14.14.130). An FSE with a waiver or variance that has caused or contributed to a grease-related Sanitary Sewer Overflow (SSO) will be required to install a grease removal device. In the event it is not practical or feasible to install a grease removal device, the FSE will be subjected to an Annual Grease Mitigation Fee
Grease removal devices shall be designed, constructed, and installed following California Plumbing Code Title 24, Part 5 and the City of Roseville Design and Construction Standards.
Grease removal devices shall be maintained by pumping the entire contents when grease and sludge have exceeded 25% of the capacity of the interceptor, including removal of entire contents each time the interceptor is pumped. The interceptor shall be pumped out at a minimum of 6-month intervals or more frequently, depending on grease load from FSE.
The grease hauler shall be licensed with the California Department of Food and Agriculture.
The permittee shall retain pumping and maintenance records for a minimum of 3 years.
These records shall be submitted quarterly to the City of Roseville and shall be readily available to City personnel inspecting the facility. At a minimum, the following information is required for the reporting records:
o Date of Service
o Volume removed
80 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
o Grease Hauler Permit number
o FOG disposal destination records
Repeated failure to submit reports on time could result in revocation of the FOG discharge permit.
The permittee shall implement Best Management Practices (BMPs) in its operation to minimize the discharge of FOG to the sewer system under RMC 14.14.060 The permittee shall notify the City of Roseville Wastewater Collection Division at 916-746- 1890 of any of the following:
o Sale, lease, or transfer of the operation for which the permit was issued. o Change of facility name
o Changes to grease removal device or remodels, additions, or alterations to FSE greater than $20,000

SSMP ELEMENT 8
8 System Evaluation and Capacity Assurance Plan
D.13 (viii). The enrollee shall prepare and implement a capital improvement plan (CIP) that provides hydraulic capacity of key sanitary sewer system elements for dry weather peak flows, as well as the appropriate design for storm or wet weather events. The plan must include (a) evaluation of those portions of the sewer system that are experiencing or contributing to SSO discharge caused by hydraulic deficiency, (b) establish appropriate design criteria to undertake the evaluation, (c) The steps needed to establish a short‐ and long‐term CIP to address identified hydraulic deficiencies, including prioritization, alternatives analysis, and schedules. The CIP may include increases in pipe size, inflow, and infiltration (I/I) reduction programs, increases and redundancy in pumping capacity, and storage facilities. The CIP shall include an implementation schedule and funding source, (d) The Enrollee shall develop a schedule of completion dates for all portions of the capital improvement program developed in (a) ‐ (c) above. This schedule shall be reviewed and updated consistent with the SSMP review and update requirements as described in Section D. 14.
8.1 Capacity Evaluation Process
Two hydraulic models were developed and used by the WWC Division (Roseville Model Project and South Placer Wastewater Authority (SPWA) Wastewater Systems Evaluation Project) to identify peak flows in each collection system component (pipe and pump station). In 2007, a hydraulic model of the City’s sewer collection system was developed using the H2OMap Sewer modeling platform (2007 Model Development Project), parallel with a trunk sewer model for the combined Roseville, SPMUD, and Placer County systems. However, the City’s sewer model was updated in 2017 to reflect existing and future demands within the City and upgrade the modeling platform to the fully dynamic InfoWorks ICM software. In addition, for the current Systems Evaluation Update, the City’s model was updated in December 2020 to reflect existing, and future projected flows from Placer County and SPMUD. The report is located at:
https://p1cdn4static.civiclive.com/UserFiles/Servers/Server_7964838/File/Government/Department s/Environmental Utilities/SPWA/Systems Evaluation Report Dec2020 Final_web.pdf While EU Engineering staff will periodically run the hydraulic model for development, the Principal Engineer and Process Engineer will review and update the system evaluation and capacity assurance plan every ten years, looking for deficiencies and opportunities for improvement.
8.2 Design Criteria
The WWC Division established 10-year 24-hour peak wet weather storm design criteria for the evaluation of existing collection system components and sizing of new collection system in the Roseville Model Project and the SPWA Wastewater Systems Evaluation Project. This included the development of wastewater flow generation factors based on water use records and flow monitoring data in the City of Roseville.
83 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
8.3 Capacity Enhancement Measures
The SPWA Wastewater Systems Evaluation included the identification of short and long-term Capital Improvement Projects (CIP) to meet current and future build-out flow projections for trunk sewers larger than 15 inches. Several deficiencies were identified in non-regional facilities which resulted in model-predicted overflows for one or more of the scenarios. Within the regional system, seven areas have been identified that either have deficiencies or could be impacted when upstream deficiencies are relieved.
Proposed improvement projects have been developed, and verified using the hydraulic model, to alleviate surcharging. The projects are summarized in Table 8-1. Each proposed project was reviewed on aerial mapping to identify potential design and constructability issues. These improvement projects were developed to sequentially decrease surcharging in downstream sewers.

8.4 Capital Improvement Plan Schedule
The WWC Division Condition Assessment CIP divided the collection system manholes and pipes into 24 groups. The first group of pipes and manholes was inspected starting in 2006 and was included in the Rehabilitation and Replacement plan developed shortly after. The city continuously inspects pipelines using NASSCO’s PACP coding standard to develop a list of assets that need rehabilitation. When defects are identified, the city evaluates the risk of failure and assigns a priority ranking to each asset. Prioritizing those assets relies on several factors, including:
Severity and extent of the defects (PACP Score).
Maintenance records and SSO occurrences
Hydraulic capacity needs and projection.
The estimated remaining useful life of the infrastructure The goal of the CIP is to develop annual project bundles of approximately $1.5 million. Using the priority rank of the pipe segment, the CIP prioritization includes one additional factor, street repairs. To minimize disruption to newly paved streets, those streets that the City anticipates repairing in the upcoming fiscal year are highest priority.
Condition assessments will be continually performed, and the CIP will be adjusted after each evaluation as follows:
• Emergency repairs will be done immediately and not be included in the CIP. • Priority will be given to those assets which lie in the street to be paved such that the repair is done before street repaving
• Pipe segments will continue to be rated on the 1 to 5 scale, with 5 being the highest priority and 1s being the lowest. So, a 5 from the previous year's assessment would be prioritized over a 4 from the current assessment.

SSMP ELEMENT 9
9 Monitoring, Measurement and Program Modification
D.13. (ix) The Enrollee shall (a) Maintain relevant information that can be used to establish and prioritize appropriate SSMP activities, (b) Monitor the implementation and, where appropriate, measure the effectiveness of each element of the SSMP, (c) Assess the success of the preventative maintenance program, (d) Update program elements, as appropriate, based on monitoring or performance evaluations, (e) Identify and illustrate SSO trends, including frequency, location, and volume.
9.1 Metrics to Prioritize SSMP Activities
The WWC Division has developed Key Performance Indicators to assess their progress in maintenance, operations, and sanitary sewer collection system management. The entire KPI worksheet is attached as Appendix 9-1. The metrics were developed to identify successes and challenges in reducing SSO frequency and impacts, improving collection system reliability, and providing capacity in the system to convey peak flows. Establishing specific KPIs for each element allows the WWC Management team to determine the degree of success of each component.
Measurable performance indicators, e.g., number of SSO occurrences, length of lines cleaned, spill response times, number of capital projects completed, etc., are used. Additionally, the KPI benchmarking metrics worksheet includes the following categories of metric information:
• System Information
• Financial Information
• Sewer Maintenance
• Performance Measures
The City tracks detailed information about SSOs. While the number of SSOs has fluctuated up and down over the past four years, the average volume per SSO has decreased. This metric demonstrates the City’s proactive efforts to contain and control SSOs and mitigate them efficiently.
In addition, the City consistently shows a significantly lower SSO rate per 100 miles of pipe versus the State and Regional averages. These measurements indicate a successful sewer management program, employee training, emergency response, and a dedication to mitigating the effects of SSOs. Table 9-1 summarizes a few datapoints of the City's SSO data and benchmarking. Table 9-2 is a 10-year comparison of SSO rates for the City of Roseville, State of California and Region 5. 87 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22

9.2 Monitor and Measure Element Effectiveness
The WWC Division implements all elements of this SSMP and has been effective in minimizing SSOs and controlling the volume of those SSOs when they occur. The WWC Division evaluates the performance of its wastewater collection system at least annually using the developed KPIs. The City will then initiate changes to this SSMP and the related programs based on the results of the KPI evaluation. In addition, the Review of the SSMP and its elements is an assigned annual training for all WWC employees. A summary of the tracked KPIs and the relation to the SSMP elements are in Table 9-3.

9.3 SSMP Performance Monitoring and Update Process
The field crews and supervisors regularly communicate regarding issues found in the field.
Management uses this information to evaluate the success of the preventative maintenance program and the frequency it is performed. This strategy ensures field crews have buy-in. They continually check their effectiveness and identify potential areas for improvement in their performance. Their suggestions are essential for the City’s success and meeting the SSMP goals.
9.4 SSO Trends
The KPI Benchmarking worksheet includes sixty-three data points to track preventative maintenance activities, enabling management staff to develop SSO trends. Based on these trends, Supervisors will adjust the preventative maintenance programs to address trends that aren’t in alignment with the SSMP goals. The KPI worksheet is populated using data from completed work orders stored in the City’s CMMS, Maximo. Assigned personnel complete data entry on a semiannual basis minimum to keep the KPI sheet updated. Table 9-4 summarizes a few points of SSO benchmarking data for the last five years.

10 Program Audit and Annual Report
D.13. (x) As part of the SSMP, the Enrollee shall conduct periodic internal audits, appropriate to the size of the system and the number of SSOs. At a minimum, these audits must occur every two years and a report must be prepared and kept on file. This audit shall focus on evaluating the effectiveness of the SSMP and the Enrollee’s compliance with the SSMP requirements identified in this subsection (D.13.), including identification of any deficiencies in the SSMP and steps to correct them.
10.1 Audit Process Summary
The City audits and updates its SSMP on a biennial basis. Updates may occur more frequently if the Superintendent discovers modifications or regulations changes between audits. The purpose of the audit is to evaluate the effectiveness of the SSMP, primarily through evaluating system metrics and performance measures. In addition, the audit evaluates the City’s compliance with the SSMP requirements, particularly the amended MRP requirements that were formalized in September 2013.
The City has invested in the resources of a local engineering firm to perform the biennial audit for the last three audit cycles. WaterWorks Engineers administers the audit much like an RWQCB audit would be. The process starts with gathering information utilizing the Water Boards PreInspection Questionnaire. This Audit Process has proven successful for the City, as significant changes have been made based on audit findings. The City will continue with this process for future audits.
10.2 SSMP Program Modifications
The WWC Division will monitor and review sewer performance metrics monthly and the status of each element of the SSMP on an annual basis. Formal SSMP audits will be performed every two years following the adoption of this SSMP. The SSMP is considered a “Living Document,” therefore the Wastewater Superintendent or Process Engineer (LROs) will initiate or direct corrective actions when SSMP deficiencies are identified between audits.
The primary responsibility for proposing and initiating modifications to the SSMP will be that of the WWC Supervisors or from input from WWC field crews. Review and approval of any amendment to the SSMP, including whether it is a major or minor change, will be the responsibility of the WWC Superintendent.

SSMP ELEMENT 11
11 Communication Program
D.13. (xi) The Enrollee shall communicate on a regular basis with the public on the development, implementation, and performance of its SSMP. The communication system shall provide the public the opportunity to provide input to the Enrollee as the program is developed and implemented. The Enrollee shall also create a plan of communication with systems that are tributary and/or satellite to the Enrollee’s sanitary sewer system.
11.1 Purpose of the Communication Program
The purpose of the Communication Program is to describe how the City will inform, educate and engage with its stakeholders, regional partners, and the public on the development, implementation, and performance of the SSMP. Another aspect of this program is to increase public awareness of services provided by the City. Raising awareness of the significance of the sewer system and the impacts businesses and residents can make on the system is of utmost importance.
11.2 SSMP Development and Implementation
There were several opportunities for public comment during the development and implementation process at City Council meetings. In addition, the SSMP has been certified by the City Council on three occasions, 2009, 2014, and again in 2019. Since certification by the City Council, the division’s SSMP has been audited on five occasions. This effort on re-writing the SSMP in its entirety will be on the City Council agenda for approval. Once approved, the document is available for download and review on the City’s website at: https://www.roseville.ca.us/sewer
11.3 Public Outreach
The City’s website is the central hub of communication for the businesses and residents of Roseville. The division’s website offers many links to assist the public with any sewer issues, explain the importance of the City’s wastewater collection system and summarize all the provided services. The division’s motto is to “Call us First” with all sewer problems. Our emergency response service van is wrapped with the Call Us First motto. Since the City owns and maintains the lower lateral from the property line to the City main, calling us first to investigate a potential blockage may save residents from an unnecessary plumbing bill. Environmental Utilities in partnership with Roseville electric publishes a monthly print newsletter, Utility News, which goes out monthly to all customers who receive a printed bill. This newsletter includes information about all aspects of utilities and how customers can reduce impacts to infrastructure. Additionally, customers get an electronic version of similar stories sent to their emails, adding to the number of messaging opportunities the city provides. The WWC Division is expanding the use of the website 96 SEWER SYSTEM MANAGEMENT PLAN | Updated 20 FEB 22
and social media to deliver proactive and deliberate messaging on WDR/SSMP requirements and program status to residential, commercial, industrial, and public stakeholders.
11.3.1Live Sewer Smart
The City belongs to a multi-jurisdictional group named Live Sewer Smart. The Live Sewer Smart website contains information for residents of Roseville and the surrounding communities to educate and encourage proper ways to reduce impacts on the sewer system. For example, the website provides residents with timely information regarding wipes in the pipes, how to properly dispose of FOG, and contact information for all agencies belonging to the program, should they have questions. In addition, there are several links to videos presenting more details that affect residential and commercial sewer systems. Live Sewer Smart can be located at:
https://livesewersmart.com/
11.4Tributary/Satellite Communication
The WWC Division routinely communicates with their satellite partners and often supports them with mutual aid sharing in terms of equipment and resources. The City has three formal agreements with tributary and satellite systems in place and currently working on a mutual aide agreement with the County of Placer Wastewater Division. The listed agreements below are included as appendices in Chapter 3:
• The Joint Exercise of Powers Agreement for the SPWA – Appendix 3-2 • The agreement regarding the operation of and use of the South Placer Regional Wastewater Facilities – Appendix 3-3.
• The Contract and Operating Agreement with Sacramento Area Sewer District and Sacramento Regional County Sanitation District – Appendix 3-4 Notice of Exemption

Project Title: Sewer System Management Plan Recertification Project Location(s): City of Roseville, CA (Citywide)
Project Description: The California State Water Resources Control Board (SWRCB) issued a Statewide General Waste Discharge Requirement (WDR), Order No. 2006-0003-DWQ in May 2006.
Under the WDR, all public entities that own or operate sanitary sewer systems greater than one mile in length that collect or convey wastewater must prepare a certified SSMP. The intent of the SSMP is to facilitate proper funding, operation and management of the sanitary sewer system in order to reduce sanitary sewer overflows, their impacts to the State's water bodies, and to protect public health.
Provisions in the WDR require periodic audits. Recertification of the SSMP must occur every five years or if significant changes have been made to the SSMP. The Roseville City Council adopted and certified the original SSMP in 2007, and the last recertification occurred in October 2022.
On June 6, 2023, the SWRCB issued an updated WDR, Order No. 2022-0103-DWQ. This order replaced the old order and provided updated guidance and regulations related to owning and operating a sanitary sewer system designed to convey sewage. This updated guidance and regulation impacted the City’s SSMP. The City underwent a required periodic audit of the current SSMP by an outside consultant, which resulted in recommendations for changes that have been incorporated into the updated SSMP. The changes included terminology changes, changes to the City’s sewer emergency response plan, naming and classification of spills for reporting purposes, as well as other minor edits and clean up items.
Public Agency Approving Project: Roseville City Council Agency/Individual Carrying Out Project: City of Roseville Environmental Utilities Department Reason why this Project is Exempt: The recertification of the SSMP qualifies for a Class 8 Categorical Exemptions as described in Section 15308 of the California Environmental Quality Act (CEQA) guidelines which states:
“Class 8 consists of….actions taken by agencies to assure the maintenance, restoration, enhancement, or protection of the environment where the regulatory process involves procedures for protection of the environment.
The project involves the recertification of the SSMP based on a periodic audit of existing sewer facilities and updating the plan based on the new Statewide General WDR issued by SWRCB. No expansion of treatment capacity is proposed; and no environmental resources will be disturbed. Consequently, the Class 8 Categorical Exemption applies.
