SPILL VOLUME WORKSHEET

The
purpose of this worksheet is to capture the data and method(s) used in estimating the volume of a spill. Since there are many variables and often unknown values involved, this calculation is just an estimate. Additionally, it is useful to use more than one method, if possible, to validate your estimate.

The following methods and tools are the approved methods in the SSMP and ERP. Check all methods and tools that you used:

 Eyeball Estimate Method
 Measured Volume Method
 Duration and Flow Rate Method (Account for diurnal flow pattern for long duration)  Other (explain) i.e., estimated daily use per capita upstream or meter @ Pump Station.

Eyeball Estimate Method: Imagine the following container(s) of water tipped over to match the quantity observed.

Size of container(s) How many of this Size? Total Volume Estimated
1 gal. bucket X 1
5 gal. bucket X 5
32 gal. trash can X 32
55 gal. trash can X 55
Total Volume Estimated
Using Eyeball Method

Measured Volume Method: (this may take several calculations and may have to break down the odd shaped spill to rectangles, circles, and polygons). It is important when guessing depth to measure several locations and use an average depth if possible. Use a separate sheet, if necessary, to sketch the shapes and show your work. Reference the West Bay Sanitary District “Initial Spill Calculation Worksheet” for appropriate formulas and conversions.

1. Draw a sketch of the spill and/or use a photocopy of block map to draw on and attach it.

2. Draw shapes and dimensions used on your sketch.

3. Use correct formula for various shapes.

Circle 3.14 x R² x D

I. BACKGROUND
In 1990, the Environmental Protection Agency (EPA) promulgated amendments to the General Pretreatment Regulations to require all Publicly Owned Treatment Works (POTW) with approved pretreatment programs to develop and implement enforcement response plans (40 CFR Part 403.8(f)(5). The EPA hoped that the POTW plans would be based on the same management principles and internal controls that have been used successfully in the National Pollution Discharge Elimination System (NPDES) program and issued its “Guidance for Developing Control Authority Enforcement Response Plans” in September 1989

1. In its guidance document, the EPA identified the principles below that describe the process for obtaining and evaluating information on industrial use compliance: identifying noncompliance; selecting an appropriate enforcement action; and resolving noncompliance in a timely, fair, and consistent manner. The principles establish a framework for managing an enforcement process, while providing flexibility to develop management procedures best suited to program operations and resources.
• Establish responsibilities, procedures, and timeframes to provide information to all le vels of the organization.
• Maintain a complete and accurate Industrial User inventory. • Collect and dispense information.
• Conduct inspections and sampling of Industrial User based on a systematic plan. • Ensure compliance screening of all relevant data.
• Perform an enforcement evaluation, where appropriate. • Institute formal enforcement action and follow-up, where necessary.

III. DEFINITIONS

1. Administrative Orders (AO) – E nforcement documents that direct Industrial Users to undertake or to cease specified activities by specified deadlines. The terms of an administrative order may or may not be negotiated with Industrial User. Administrative orders may incorporate compliance schedules, administrative penalties, and termination of service orders. Administrative orders include:
a) Finding of Noncompliance – A written notice instructing the Industrial User to identify and correct causes on noncompliance. The notice may require a response from the Industrial User identifying corrective actions taken.
b) Consent Order – D ocuments noncompliance and includes actions required to be accomplished by specific dates (milestones). Consent Orders are developed during compliance meetings and terms are agreed upon by both parties.
c) Compliance Order – D irects the Industrial User to achieve or restore compliance by a date specified in the order. A compliance order is often a stipulated agreement that may include a compliance schedule, the payment of monetary penalties or cost recovery, and the imposition of fines when milestones are not met.
d) Cease and Desist Order (CDO) – Directs an Industrial User to cease illegal or unauthorized discharges immediately or to terminate its discharge altogether.
e) Termination of Service or Permit revocation – A notification to an Industrial User of the intent to revoke the Industrial User’s Permit or the termination of service.

2. Administrative Penalty (AP) – A punitive monetary charge assessed by the Control Authority rather than a court. The purpose of the penalty is to recover the economic benefit of noncompliance and to deter future violations.

3. Average Monthly Discharge Limit – The highest allowable average of daily discharges over a calendar month, calculated as the sum of all daily discharges measured during that month divided by the number of days on which monitoring was performed (except in the case of fecal coliform).

4. Best Management Practice (BMP) – Schedules of activities, prohibitions of practices, maintenance procedures, and other management practices to implement the prohibitions listed in (Sunnyvale Municipal Code (SMC)) Section 12.12.020 (a) and (b), and the local limits on wastewater in Section 12.12.120(c). BMPs also include treatment requirements, operating procedures, and practices to control site runoff, spillage or leaks, sludge or waste disposal, or drainage from raw materials storage.

14. Compliance Time Schedule – A timetable for the implementation of corrective actions (milestones) by an Industrial User to achieve consistent compliance with all pretreatment program requirements.

15. Consent Order – A Consent order , also known as a Time Compliance Schedule (TCS), documents noncompliance and includes actions required to be accomplished by specific dates (milestones). Consent Orders are developed during compliance meetings and terms are agreed to by both parties.

16. Consistently Achieving Compliance (CC) – Compliance w ith all applicable federal and local standards as confirmed by POTW sampling, showing no more than one violation of any individual parameter during the quarter, if such violation was not an obvious continuation of a problem detected in the previous quarter and is not a severe violation of the City sewer ordinance.

Attachment 2

VI. IDENTIFYING AND INVESTIGATING INSTANCES OF

NONCOMPLIANCE

1.0. INDUSTRIAL USER INVENTORY
Each year an updated list of Industrial Users within the service area is compiled and submitted with the Pretreatment Program annual report . The list indicates whether Industrial Users are regulated by categorical standards or local limits, and includes the discharge status during the year. Throughout the year, the Industrial User inventory is continually updated as new Industrial Users are identified or they cease discharge to the sanitary sewer. Among the methods used to identify potential Industrial Users are:
• Review of building plans submitted to the City for construction permits , as ref erred by the Building Division;
• Inspection of commercial areas to identify new tenants and industries previously identified as zero discharge;
• Annual review of internet yellow pages;
• Referral by other City departments;
• Review Water Board list of industries subject to Stormwater General Industrial Permit; • Direct contact by business representatives; and
• Review of new business license list from the Finance Department.

These methods are employed annually and are particularly effective when all resources are utilized.

When potential dischargers to the sanitary sewer are identified, the business is contacted through a telephone call or inspection to determine the nature of its operations. Businesses that discharge a regulated wastestream are required to submit an industrial wastewater discharge permit application. A record of all businesses contacted is maintained in the files and database, regardless of whether the business is regulated by permit or Best Management Practices or does not discharge to the sanitary sewer.

2.0. INSPECTION PROGRAM
In accordance with 40 CFR Part 403.8(f)(2)(v), the Pretreatment Program performs a minimum of two compliance inspections per year for every SIU. Two general types of inspections are conducted: scheduled and demand, with additional inspections performed throughout the year as needed. More frequent inspections should be conducted when considering one or more of the following criteria:
• The Industrial User’s potential to adversely affect the POTW’s operations (e.g., the type and/or concentration of pollutants in the Industrial User’s discharge); • The volume and variability of the discharge;
• The type and reliability of control methods used to achieve compliance; • The quantity and nature of materials stored or in use and their relative risk of accidental spill; • POTW problems known or suspected to have been caused by the Industrial User; • A history of complaints, if any, at the facility;
• The Industrial User’s compliance history and
• The period of time since the last inspection.

Attachment 2

The Environmental Compliance Inspector prepares an annual monitoring and inspection plan that specifies the number of compliance inspections and monitoring events scheduled for each SIU. A description of the general types of inspections and the situation in which they would be applied follows:

2.1. Scheduled Inspections
• Annual Compliance Inspection – An inspection, based upon 40 CFR Part 403.8(f)(2)(v), in which Pretreatment Pr ogram staff performs a minimum of one compliance inspection for each permitted Industrial User per year. While the inspection is typically scheduled, it does not mean that inspectors must notify the facility prior to each inspection . Rather, a scheduled in spection may be more effective since arrangements can be made for accompanying personnel who are knowledgeable of the industry’s operations. This routine compliance inspection is conducted to examine the environmental activities of an Industrial User, ensure they comply with regulations relevant to their facility and to generate a permit or enforce an existing permit that identifies the responsibilities of the Industrial User. • Follow-Up Inspection – An inspection generally performed in order to obtain information unavailable during the routine compliance inspection or to determine compliance or progress toward a time schedule or corrective action. Scheduling a follow-up inspection may be necessary to involve personnel who have additional information or knowledge crucial to the operation of the facility . Like a routine compliance inspection, it is not required that an inspector notify the facility prior to the inspection. • Facility Modification Inspection – An inspection typically initiated by a request from a facility. Requests for an inspection from a facility may be due to modifications in their operation, including installation of new equipment, removal of equipment, relocation of processes, or closure of a facility . A facility may request an inspection to ensure they are compliant with their permit requirements.

2.2. Demand Inspections
• Enforcement Response Inspection – An inspection performed in response to an incident that is occurring or has occurred at a facility including spills, sewer line blockages, excursions, illegal dumping, or upset of pretreatment systems. This inspection may be initiated through a call from an industry representative, another environmental agency, public complaint, or violations discovered during routine sampling. • Preliminary Inspection – An unannounced inspection conducted at non-permitted (commercial) facilities where it is suspected that the facility may be performing an operation requiring a discharge permit .

Occasionally, through inspection of new and existing non- permitted facilities, operations are discovered that would require a discharge permit . It is the goal of the City of Sunnyvale to assess every business to characterize the business activity and its need for permitting or continued inspection.

3.0. MONITORING PROGRAM
The City of Sunnyvale generally performs all required compliance sampling in lieu of the SIU. In cases of continued noncompliance, the City may require the SIU to share the cost burden of demonstrating compliance by requiring increased monitoring to be conduct ed by an Environmental Laboratory Accreditation Program certified laboratory, on behalf of the SIU.

Discharges from SIUs are generally monitored each quarter by composite sampling, grab sampling, and continuous pH monitoring where feasible. SIUs subject to Categorical Standards are monitored for all applicable pollutants in accordance with 40 CFR 136 procedures for sample collection, handling, and analysis . In general, composite Attachment 2

samples are collected to determine compliance with federal and local limits for metals and to measure revenue parameters. Grab samples are collected for pollutants where composite sampling is inappropriate such as oil and grease, cyanide, and volatile organics. Grab samples for metals may be taken in addition to composite sampling where deemed appropriate by the Environmental Compliance Inspector . pH recording is performed quarterly through grab or continuous chart recording if deemed appropriate. Monitoring is unannounced except in limited cases where security protocols prohibit access without prior clearance and escort . Wastewater samples are collected after process or pretreatment and prior to combining with sanitary or non-process flows.

Monitoring at frequencies greater than once per quarter is conducted at f acilities with demonst rated noncompliant discharge limits. Frequencies are determined by the Environmental Compliance Inspector, using the EPA Guidance Manual (Industrial User Guidance Manual), the Sunnyvale Pretreatment Program Guidance for Determining Monitoring Frequencies, and this Enforcement Response Plan. Monitoring frequencies are individually evaluated for each SIU and determined based on the need for representative sampling data to evaluate compliance and to meet minimum monitoring requirements.

Sampling events may be random and are unannounced. Since almost all sampling structures are located within the facility, the Environmental Compliance Inspector or Laboratory/Field Technician collecting the sample checks the final effluent pH, including any previous day’s pH data available for review, and the general functioning appearance of the pretreatment system. They will also verify compliance with permit conditions such as maintaining proper pH calibration records and performing required process control monitoring. Facility personnel are notified of any significant problems requiring immediate attention at the pre treatment system, unusual sample appearance, or any other problems observed in the surrounding area which may negatively impact spill control or storm or sanitary sewer discharges.

Chain of Custody documentation is maintained for all industrial samples. A Chain of Custody form is created prior to collection and is assigned a unique number to identify the sampling event. This number appears on all sample collection bottles and the Chain of Custody form. This number is used to identify results reported by the laboratory. Staff record pertinent information about the sampling event on the Chain of Custody form and maintain custody of all samples until they are relinquished to the laboratory. Samples are secured in an area of the laboratory that is accessible to authorized personnel only. Information regarding the sampling event, including test results, is stored in a computer tracking system. A hard copy version is stored in the Industry’s file.

Within 30 days of becoming aware of a sampling violation , the City will repeat the sampling and analysis unless the City notifies the IU of the violation and requires the IU to perform the repeat analysis. This sampling and analysis is required by 40 CFR 403.12(g)(2).

Attachment 2

VII. INDUSTRIAL USER REPORTING
General Pretreatment Regulations at 40 CFR 403.12 set forth five basic reporting requirements that apply to Industrial Users subject to specific categorical pretreatment standards. Categorical Industrial Users must comply with these Federal reporting requirements, even if the Control Authority has determined that the local limit(s) requirement is more stringent than the categorical standard. Pursuant to 40 CFR, these reporting require ments are:
• Baseline Monitoring Report (403.12(b)), including a compliance schedule, when necessary, for meeting categorical pretreatment standards (403.12(c)).
• Report on Progress in Meeting Compliance Schedules (403.12(c)) • Report on Compliance with Categorical Pretreatment Standard Deadline (403.12(d)). • Periodic Report on Continued Compliance (403.12(e)).
• Notice of Potential Problems, including Slug Loading (403.12(f)).

The Pretreatment Program requires all potential SIUs submit a Wastewater Discharge Permit Application (WDPA) prior to the commencement of discharge, which contains information listed in 40 CFR Part 403.12 (b)(1) -(5), and estimates of information requested in paragraphs (b)(4) and (5). As permissible by 40 CFR Part 403.12(g), because the Pretreatment Program conducts all minimally required sampling and analysis in lieu of the Industrial User, the Industrial User is not required to submit the compliance certification required under 40 CFR Part 403.12 (b)(6) and (d). Similarly, because the POTW itself collects all the sampling and analysis information required for the report , and that all other required information is included in the WDPA, new Industrial Users are not required to submit a separate BMR report in addition to the WDPA.

Attachment 2

VIII. Enforcement Procedures
When enforcement action is warranted, the appropriate response can usually be determined by referencing the Enforcement Response Guide ( Attachment A). A more or less severe enforcement action may be justified depending on the nature of the violation, abatement actions taken by the Industrial User, previous compliance history, and the effects of the violation on the POTW or receiving water.

1.0. TIMEFRAMES FOR ENFORCEMENT RESPONSE
The timelines of any enforcement action is important if escalated enforcement actions are necessary due to continued noncompliance. The Industrial User is notified of the violation in a timely manner to provide a better opportunity to identify potential causes of the violation before the circumstances surrounding the violation are lost. Finally, prompt notification with an expectation of an equally prompt response by the Industrial User demonstrates that the POTW is serious in addressing noncompliance and enforcing discharge regulations.

The timeframes listed below establish the maximum period in which enforcement actions are expected to be taken. It is desirable that any enforcement action be taken as soon as practical. • All violations will be identified and documented within five days of receiving compliance information. • Initial enforcement responses (informal and formal) will occur within 10 days of identifying a violation. • Follow-up actions for continuing or recurring violations will be taken with in 60 days of the initial enforcement response.
• Violations that threaten health, property, or environmental quality are considered emergencies and will receive immediate response such as halting the discharge or terminating service. • All violations meeting the criteria for significant noncompliance will be addressed through formal enforcement within 30 days of the identification of significant noncompliance. • Within 30 days of becoming aware of a sampling violation the City will repeat the sampling and analysis unless the City notifies the IU of the violation and requires the IU to perform the repeat analysis (40 CFR 403.12(g)(2)).
• Each year, all Significant Industrial Users in Significant Noncompliance (SNC) within the last twelve months will be reported in the local newspaper (40 CFR 403.8(f)(2)(viii)).

Exception to Notification Procedure
An exception to the timely notification of violations by Industrial Users is when evidence indicates intentional behavior and possible criminal activity. Such instances include information received from an employee reporting illegal dumping or dumping detected during collection system monitoring. In any such cases, notification to the Industrial User is withheld as an investigation is conducted, and routine inspections and monitoring are suspended.

2.0. TYPES OF ENFORCEMENT ACTION
A range of enforcement response mechanisms are available . Enforcement responses may include informal responses such as a Verbal Notice, or a more formal, response such as a written Warning Notice or N otice of Violation, Administrative Order (with or without penalties), judicial action, and /or termination of service. The Attachment 2

appropriate enforcement action can be determined through the Enforcement Response Guide (ERG), found in Attachment A. The ERG reflects the following concepts:
• The Industrial User is notified when a violation is found. • If the Industrial User (or POTW) repeats the analysis for an effluent violation, and no further noncompliance is identified, no further response may be necessary. • For most violations, the POTW should receive an explanation and, as appropriate, a plan from the Industrial User to correct the violation within a specified time period. • If the violations persist or the explanation and the plan are not adequate, the POTW response should become more formal and commitments (or schedules, as appropriate) for compliance should be established in an enforceable document.
• The enforcement response selected should be related to the seriousness of the violation, and enforcement response should be escalated if compliance is not achieved expeditiously after the initial action. A serious initial violation requires a formal enforcement action.

By incorporating criteria for evaluating noncompliance and determining the appropriate enforcement action, the ERG provides a level of response appropriate to the violation. Additional criteria, which are not described i n the ERG, can be used to establish an appropriate enforcement action, which may be more or less stringent. These criteria are listed in Appendix A - Criteria for Evaluating Enforcement Response

1. 1 USEPA Guidance for Developing Control Authority Enforcement Response Plans (1989) Attachment 2

IX. TYPES OF VIOLATIONS

1.0. MINOR VIOLATION:

Minor violations include:
• Exceeding a discharge limit by 1.4 times or less for BOD, TSS, fats, oils and grease, or 1.2 times or less for all other pollutants except pH and toxic pollutants , or 1.4 times or less for conventional pollutants.
• pH that is less than 6 but is greater or equal to 5 for less than an hour. • pH that is more than 10.5 but less than or equal to 11.5 for less than an hour. • Submitting a required report, no more than 5 days late. • An isolated violation of a permit condition.

2.0. MODERATE VIOLATION:

Moderate violations include:
• Exceeding a discharge limit by 5 times or less for toxic and conventional pollutants. • pH less than or equal to 4 to but less than 5 for any duration. • pH that is greater than or equal to 11.5 but less than 12.5 for any duration. • Submitting a required report 6 or more days late but not more than 30 days late. • Recurring or uncorrected violations of a permit condition.

3.0. SEVERE VIOLATION:

Severe violations include:
• Exceeding a discharge limit by more than 5 times the limit for toxic and conventional pollutants.
• pH less than 4 or greater than 12.5 for any duration. • Submitting a required report more than 30 days late, and • Any violation meeting the definition of Significant Noncompliance.

Attachment 2

Attachment 2

X. ENFORCEMENT ACTIONS
The City follows a tiered approach for issuing enforcement actions to violations. Following are the enforcement tools available to pretreatment inspection programs:
• Distribution of Educational Materials
• Verbal Notice (VN)
• Warning Notice (WN)
• Notice of Violation (NOV) with Administrative Citation Referrals (ACRs) • Administrative Citation (AC)
See Enforcement Response in Figure 1 for a flow diagram related to the Enforcement process.

When considering the type of enforcement action to be taken, the Enforcement Response Guide (ERG) is used.

City staff gives the RP every reasonable opportunity to comply with directives issued to them. City staff acknowledges that education plays a vital role in environmental enforcement. The use of verbal education, outreach materials, and recommendations in coordination with more formal enforcement assists City staff in ensuring compliance.

All violations and corrective actions require follow-up by City staff to ensure appropriate compliance.

See Enforcement Response Guide in Attachment A for a schedule of enforcement actions.

1.0. DISTRIBUTION OF EDUCATIONAL MATERIALS
The ECI gives the RP any relevant educational outreach materials that address the violation(s). The ECI verbally notifies the RP of future enforcement escalation should violations not be addressed. If the responsible party is not identified, educational materials are distributed to all identifiable dischargers at the site.

2.0. VERBAL NOTICE (VN)
A warning communicated to the Industrial User orally. A VN does not require a response from the Industrial User and may be given during an inspection or by phone call. The violation is usually very minor or within the range of analytical error for discharge violations.

A VN may require a written response from a facility. However, the ECI notifies the RP of future enforcement escalation should violations not be addressed.

See the Inspection Notice in Attachment B.

3.0. WARNING NOTICE (WN)
A WN is an official notice of noncompliance and is generally issued as an escalation from the VN . A WN is issued when a when a moderate violation has occurred or a violation that was issued a VN was not resolved within the compliance timeline. A WN may require a written response from a facility and directs the RP in writing to take immediate corrective action(s), within a compliance timeline.

Attachment 2

The ECI notifies the RP of future enforcement escalation if the violation(s) is not addressed. A WN is documented on the Inspection Notice and the applicable database(s). A WN may also be a separate written document sent to the facility.

4.0. NOTICE OF VIOLATION (NOV)
An official notice that a significant violation of discharge regulations has occurred and is accompanied by an Administrative Citation Referral (ACR). An NOV is generally issued as an escalation from the WN, for a severe actual violation. An NOV is issued when a violation is not resolved within the compliance timeline. An NOV may require a written response from the facility and it directs the RP in writing to take immediate corrective action(s).

The ECI notifies the RP of future enforcement escalation if the violation(s) is not addressed. An NOV is documented on the Inspection Notice or may be a separate written document sent to the facility and documented in applicable database(s).

An ACR gives the RP notice that the violation has been referred for an Administrative Citation. Multiple violations meriting ACR enforcement will be documented on the same notice.

5.0. ADMINISTRATIVE CITATION (AC)
The issuance of an AC indicates the increase in magnitude of the violation(s) beyond WN, while requiring immediate response from the RP to resolve/cease the violation(s). An AC is generally issued for severe violations, for unresolved repeat violations , or when previous enforcement fails to achieve compliance. An AC is delivered after an ACR has been issued with an NOV at the time of the inspection. Additional ACs may be issued to different RPs for the same violation (s) (e.g., the business owner and the property owner, the owner and the general contractor, or the general contractor and the subcontractor). An AC carries a monetary penalty and always requires approval from the SECI.

See the Administrative Citation in Attachment C.

6.0. ADMINISTRATIVE ORDER (AO)
Administrative Orders (AO) – E nforcement documents that direct Industrial Users to undertake or to cease specified activities by specified deadlines. The terms of an administrative order may or may not be negotiated with Industrial Users. Administrative orders may incorporate compliance schedules, administrative penalties, and termination of service orders. Administrative orders include:
• Finding of Noncompliance – A written notice instructing the Industrial User to identify and correct causes on noncompliance. The notice may require a response from the Industrial User identifying corrective actions taken.
• Consent Order – Documents noncompliance and includes actions required to be accomplished by specific dates (milestones). Consent Orders are developed during compliance meetings and terms are agreed upon by both parties.
• Compliance Order – Directs the Industrial User to achieve or restore compliance by a date specified in the order. A compliance order is often a stipulated agreement that may include a compliance schedule, the Attachment 2

payment of monetary penalties or cost recovery, and the imposition of fines when milestones are n ot met.
• Cease and Desist Order – D irects an Industrial User to cease illegal or unauthorized discharges immediately or to terminate its discharge altogether.
• Termination of Service or Permit revocation – A notification to an Industrial User of the intent t o revoke the Industrial User’s Permit or the termination of service.

7.0. COMPLIANCE MEETING (CM)
A CM is a meeting with the Industrial User to discuss the causes of noncompliance, corrective actions to achieve compliance, and the time frames for the implementation or corrective actions.

8.0. TIME COMPLIANCE SCHEDULE
A Time Compliance Schedule is a timetable for the implementation of corrective actions (milestones) by an Industrial User to achieve consistent compliance with all pretreatment program requirements.

9.0. ADMINISTRATIVE HEARING
Any recipient of an AC may contest the violation by completing a “Request for Hearing Form” and returning it to the City, together with a deposit of the total fine amount, within 15 days from the date of the AC. The RP requesting the hearing shall be notified in writing of the time and place set for the hearing at least 10 calendar days prior to the date of the hearing. If the City staff submits an additional written report concerning the AC to the Hearing Officer (HO) for consideration at the hearing, then a copy of this report shall also be served to the person requesting the hearing no less than five calendar days prior to the date of the hearing.

The City Manager shall designate the HO for the AC hearing. A hearing before the HO shall be set for a date that is not less than 15 calendar days and not more than 60 calendar days from the date that the “Request for Hearing” is filed. The RP has one opportunity to reschedule the hearing and must do so promptly to save their opportunity for hearing. Failing to appear will result in the loss of the deposit and opportunity for hearing. At the hearing, the RP contesting the AC shall be given the opportunity to testify and to present evidence concerning the AC. The AC and any additional report submitted by the City staff shall constitute the primary evidence of the respective facts contained in those documents. The HO may continue the hearing and request additional information from Cit y staff or the recipient of the AC prior to issuing a written decision.

After considering all the testimony and evidence submitted at the hearing, the HO shall issue a written decision to uphold or cancel the AC and shall state in the decision the reasons for that decision. The decision of the HO shall be final. If the HO determines that the AC should be upheld, then the HO shall determine the amount of the fine to be imposed, and shall specify a date by which the fine is to be paid to the City. The RP shall be served with a copy of the written decision.

Any RP aggrieved by an administrative decision by the HO regarding the disposition of an AC may obtain review by filing a petition for review with the Municipal Court in accordance with the timelines and pro visions set forth in Government Code Section 53069.4.

Wastewater
Sunnyvale provides wastewater management services as a municipal utility.

Wastewater collection and treatment is one of the core services the City provides to Sunnyvale residents and businesses. The City ’s Wastewater Fund Long- Term Financial Plan includes sewage collection and treatment, environmental protection, regulatory compliance, and maintenance of the City ’s aging collection and treatment systems.

Major Wastewater Projects
Wastewater Collection Systems. In general, the collection system projects related to wastewater management address critical and immediate needs. Projects address manholes, sewer pipes, and rebuilding sewer lift stations. The largest of these efforts is the replacement of sewer mains with funding totaling $37 million over the next twenty years. The proposed budget also allocates an additional $6.5 million to perform emergency repair and replacement work.

Peery Park Wastewater Capacity Projects. The budget includes capacity increa
se projects to accommodate increasing sewage flow from Peery Park development. The estimated budget is $21 million with design commencing in FY 2024/25 and construction completed in FY 2027/28.

Sewer Capacity Enhancement Projects. Several sewer capacity projects were recommended in a consultant modeling study completed in 2022. Sewer projects along Mary Ave, California Ave, and upgrading the sewer pump station on Arques Ave are scheduled to start design in FY 2026/27 with construction completed in 2034/35 at an estimated cost of $14.9 million. Construction is scheduled to be phased over seven years.

Water Pollution Control Plant Biosolids Processing. This project addres
ses the removal, processing, and disposal of accumulated sediment from the Plant’s Oxidation Ponds, as well as digester cleaning. These services will be necessary until a permanent thickening and dewatering building can be constructed as part of the Cleanwater Program.

Water Pollution Control Plant Permanent Chemical Storage Structure.

This project consists of the construction of a new permanent chemical storage tank facility. About six months ago, temporary chemical tanks were installed to test the effectiveness of multiple chemical regimes to mitigate the pond algae.

The new chemical regimes have proven to be effective, however, a permanent tank storage facility is needed to store the chemicals. This includes a permanent concrete pad, one chemical storage tank and dosing station. The current temporary chemical storage tanks have an engineered useful life of about 2 years in the current construction.

Project Description/Scope/Purpose
City staff routinely reviews CCTV inspection reports to identify defects and prioritize repairs for the sewer system. The purpose of this project is to provide sufficient funding for emergency repairs of high-risk defects, particularly those that are highly severe or located close to critical waterways and facilities. These repairs must be addressed promptly due to the potential consequences of inaction, such as pipe collapses, service disruptions, sewage spills, regulatory violations, and legal liabilities, which could result in costly clean-up and repair efforts.

Due to the backlog of high-risk defects, which stands at about 500 pipes awaiting review and prioritization, plus the addition of even more high-risk defects from future CCTV inspections, the City has a pressing need to allocate additional resources towards repairs. The average cost per defect is about $15,000 (could be up to $50,000 depending on scope and complexity); the City has already completed over 40 such repairs in the current fiscal year, almost draining the available budget. To address the mounting backlog and ensure the ongoing safety of the sewer system, staff is proposing to increase the project budget to $900,000 for the next two fiscal years. After the completion of the most pressing repairs, the budget for this project can return to $225,000 per year.

This project is different from other sewer main replacement projects because its focus is to address emergency spot repairs instead of replacing the entire pipe, which are usually planned and executed through large contracts. This project is aimed to provide immediate funding for emergency work that requires swift action to maintain the reliable functioning of the sewer system.

Project Evaluation and Analysis
The alternative is not to fund this project and delay the needed repairs until funds are requested and approved by Council on a case by case basis. These repairs are of an urgent nature most of the time, and delay could result in adverse effects for public health and the environment should overflows occur. The City could also be subject to penalties and fines from regulatory agencies should sewage discharges occur as result of deferring an emergency repair. Delaying can also result in higher repair costs.

Fiscal Impact
Repairs typically range from $15,000 for a spot repair to over $100,000 for sewer repairs on a major thoroughfare. The requested increase in annual budget over the next two years will provide the necessary funds for emergency repairs.

Project Description/Scope/Purpose
This project provides funds for the rehabilitation of Storm Pump Station #2, east of Baylands Park. Sunnyvale operates two storm pump stations to pump accumulated storm water into tributaries to the San Francisco Bay. These are required due to areas of the City that are close to sea level and could suffer flooding, particularly during large storms and exceptionally high tides. The current configuration of Storm Pump Station #2 consists of a structure with six pumps (one small electric and five natural gas- powered engines), a storage pond surrounded by a levee, and an access road to get to the facility. Several capital aspects of the facility must be periodically funded.

This station was built in 1962. The pumps and motors are original and need to be replaced. The redesign includes replacing the existing natural gas engines with more efficient electrical submersible pumps with an onsite generator for an emergency back-up power source. Several upgrades are also included for code and regulatory compliance as well as operational efficiency including:
rehabilitation or replacement of discharge piping; installation of trash capture devices; upgrading electrical control panels and accessories to current standards; replacing Supervisory Control and Data Acquisition (SCADA) controls, which includes the installation of a flow meter; inlet and wet well improvements; and addressing other pump station rehabilitation items identified in the feasibility study.

Project Evaluation and Analysis
This project is necessary to maintain existing essential infrastructure of the Wastewater Utility. Failure of this station to operate would result in flooding of the northeast portion of Sunnyvale.

Fiscal Impact

Project Description/Scope/Purpose
Every five years, the Utility Billing Division in the Department of Finance performs a cost of service study of the wastewater system to update and align the City's wastewater rates with the costs associated with providing service. Staff works with a consultant to develop a cost of service model and populate the model with current data. The study generates a cost of service for each customer class and recommends adjustments to the City's rates and rate structure to ensure costs are recovered on an equitable basis from the different customer classes.

The most recent analysis was done in FY 2017/18. This project provides funding to hire a consultant that will support staff's effort to refresh the analysis every five years.

Project Evaluation and Analysis
City policy and state law require that the rates be periodically restructured in a way that equitably allocates program costs among rate payers (Council Policy 7.1.B.1.4). An alternative to using a consultant would be for staff to conduct the cost of service study.

However, city resources and staff hours are not available for a project of this magnitude. If the project is not completed, it is possible that rates will not reflect actual costs, will not provide the complete cost-recovery needed to provide wastewater services, and costs may not be equitably allocated per city policy.

Fiscal Impact
The studies completed through this project will ensure utility rates are consistent with the true cost of providing the utility service and provide enough revenue to operate the utility. This is a requirement of Proposition 218, and the results of the analysis will be used to determine utility rates for each customer class. The next study is being delayed until FY 2024/25 so that the study can reflect the WPCP Master Plan updates currently in progress.

Project Description/Scope/Purpose
This project is for repair, replacement, and rehabilitation of sewer pipes and associated appurtenances, including but not limited to, manholes, lateral piping, and surface restoration. The goal of this project is to reduce sanitary sewer overflows as well as reduce inflow and infiltration which results in higher treatment costs. Alternative technologies are evaluated to select the best, most cost-effective rehabilitation method for each location. These methods include traditional open-trench replacement as well as "trenchless" methods including pipe-bursting/replacement, or Cured-in-Place pipe lining.

The City has over 310 miles of sewer lines, ranging from 6 inches to 48 inches in diameter, and valued at over $330 million.

Many of the sewer lines are over 50 years old and have reached the end of their useful life. Pipe failures have been increasing.

Recent video inspection has revealed significant deficiencies at multiple locations that require rehabilitation to prevent failure.

Specific projects will be identified based on need from CCTV findings and as identified in the Wastewater Master Plan. The projects will be constructed in a three-year cycle, with the first two years for planning and design and the third year for construction. Projects will be built to fall within allocated budget, therefore linear footage of pipelines to be replaced/repaired/rehabilitated will vary.

Project Evaluation and Analysis
This project is necessary to comply with regulatory standards which require agencies to rehabilitate and/or replace sanitary sewer system piping and associated components. The alternative to replacement of sewer pipes in poor condition would be to repair them segment by segment on an emergency basis. Public health and the environment could be threatened, and fines could be levied against the City, should overflows occur as a result of a structural failure. Further, repairing or replacing segments of pipeline on an emergency basis would be significantly costlier than scheduled replacements.

Fiscal Impact
This project is funded by Wastewater Management Fund revenues. The projects will be constructed in a three-year cycle, with the first two years for design including permitting and the third year for construction. Projects will be built to fall within allocated budget, therefore linear footage of pipelines to be replaced/repaired/rehabilitated will vary.

Project Description/Scope/Purpose
This project is for the repair, replacement, and rehabilitation of storm drain pipes. The City has over 320 miles of storm lines, from 6 inches to 84 inches in diameter. Many of the lines are 50 or more years old. This project repairs, replaces, or rehabilitates storm mains as they are identified or as identified in the Wastewater Master Plan CIP list. Alternative technologies are investigated to apply the best method for each location, including open-trench replacement, "trenchless" pipe- bursting/replacement, or pipe-lining. Storm systems are not generally subjected to the same conditions as sewer systems, and can typically be expected to last longer.

The project additionally provides for repair, replacement, or rehabilitation of associated storm water conveyance components that could include manholes, catch basins, drain inlet grates and lids, and other related system components. Design of the Remington Court storm drain outfall into Stevens Creek was completed in 2021, with construction of the outfall repairs completed in December 2022. Funding includes a study to evaluate sources of storm water inflow into the sanitary sewer system. The study will list and prioritize these locations and propose corrections for future capital improvement projects. The Sources of Storm Water Inflow into Sanitary System Study 2021 9UW-21-01 is currently being finalized.

This project also may include condition assessment; cleaning and debris removal to conduct condition assessment; and flow monitoring as needed to diagnose system structural and performance issues. Specific task identification relies upon condition assessment methods, most commonly the findings of video inspection, to identify locations in need of replacement or rehabilitation each year. This project is necessary to assure storm water conveyance and mitigate system failures which can result in flooding.

Project Evaluation and Analysis
The other alternatives to the project are either not to fund it or to delay funding to later years. However, if funding is not provided or delayed for too long, structural failures in the system due to aging pipes might develop that could cause flooding and property damage. Emergency repairs would then be necessary, which are usually more expensive than scheduled replacements.

Fiscal Impact
This project is funded by the General Fund.

Project Description/Scope/Purpose
The Water Pollution Control Plant (WPCP) Biosolids Processing project was initiated in 2009 to address the accumulation of biosolids (sediments) on the bottom of the WPCP Secondary Treatment Oxidation Ponds. This project provides funding for the removal, processing, and disposal of accumulated sediments from the Plant's Oxidation Ponds.

The WPCP Biosolids Processing project also provides funding for the dewatering and beneficial reuse of anaerobically digested biosolids from the Plant's solids handling process until new solids dewatering facilities are constructed as part of the ongoing Sunnyvale Cleanwater Program.

The Biosolids Handling scope of work provides for the removal of ponds solids by dredging and preconditioning before sending those biosolids to a centrifuge for dewatering. The WPCP Biosolids Processing project also provides funding for the dewatering and disposal of biosolids generated by the WPCP Anaerobic Digesters. After dewatering, those concentrated solids are hauled off-site for land application (beneficial reuse).

Funding can also be used to clean digesters when the same contractor provides one or both of the previously mentioned services (pond and/or digester solids processing). This is a cost and logistical advantage for the City as much of the same equipment is used in the cleaning process.

Project Evaluation and Analysis
The WPCP is a heavily regulated wastewater treatment facility with strict effluent discharge requirements. The ammonia concentration in the WPCP final effluent is one of the plant effluent limits. Reduced volumetric treatment capacity within the Oxidation Ponds due to solids accumulation can directly affect the ammonia removal ability of the ponds and, if not addressed, may increase the concentration of ammonia in the effluent.

Over the last decade, the WPCP held several technical meetings with scientists and engineers to determine the best course of action to minimize the chance of process failure of the Secondary Oxidation Ponds. During those meetings, it was concluded that dredging the ponds at a rate faster than accumulation is the most prudent approach.

The rate of capacity restoration of the ponds is slow and needs to be spread over several years. The anaerobic digestion of wastewater solids provides fuel for power generation and volumetric reductions of plant-generated solids. Both save operating costs associated with purchasing power, handling, and disposal of plant-generated biosolids.

Fiscal Impact
The project costs are reflected in the agreement with the current contractor providing the handling, processing, and disposal services. $280,000 in operating impacts have been added to cover the ongoing hauling and disposal costs related to biosolids dewatering and disposal after 2027, once a new Thickening and Dewatering Building has been constructed.

Project Description/Scope/Purpose
The City of Sunnyvale is one of 15 members of the Santa Clara Valley Urban Runoff Pollution Prevention Program (SCVURPPP). SCVURPPP was formed to implement the National Pollution Discharge Elimination Permit (NPDES) issued to the cities, county, and Valley Water who discharge storm water to the San Francisco Bay. These 15 agencies have signed a Memorandum of Agreement (MOA) and pay annual assessments to cover the cost of programmatic activities related to implementing the NPDES Permit.

The MOA provides for the selection of one of the members as the program's Contracting and Fiscal Agent. The Contracting and Fiscal Agent provides audited financial statements, billing, and payment services for SCVURPPP. It also acts as the awarding authority for any contracts that the agency is required to enter into.

Project Evaluation and Analysis
The City of Sunnyvale is providing billing and payment services for SCVURPPP and acting as the awarding authority for any contracts that the agency is required to enter into during the course of its normal operations under the MOA.

Fiscal Impact
Total costs of the project are covered by assessments to the SCVURPPP members. The City of Sunnyvale's assessment under the MOA is 7.25% of the total annual program budget.

Funding Sources
Revenue from this project goes to the General Fund. This project monitors Santa Clara Valley Urban Runoff Pollution Prevention Program reimbursement of reasonable and customary costs, pursuant to the SCVURPPP MOA.

Project Description/Scope/Purpose
This project will provide for the multi-disciplinary (structural, civil, electrical, corrosion) engineering review of the Water Pollution Control Plant (WPCP) on a periodic basis. As part of long-range infrastructure planning for the WPCP, a periodic condition assessment of plant facilities is needed in order to prioritize repair/replacement projects and provide for a systematic approach to capital budget planning. The next assessment is scheduled for FY 2030/31, which is five years after the anticipated completion of the first phase of the new Water Pollution Control Plant.

The information will be used to define existing conditions and priorities as part of the ongoing predictive maintenance efforts.

Funds should be allocated at five year intervals to maintain this level of evaluation. An assessment should be completed periodically to track the condition and deterioration of assets so that repair/replacement projects can be timed appropriately, and the various needs can be prioritized. This data will then be input into the plant’s asset database for evaluation and comparison to be used in managing the WPCP infrastructure. The schedule and cost for these assessments will be reevaluated at the completion of the Master Plan.

Project Evaluation and Analysis
Periodic assessment and comparison of actual condition of WPCP assets with agreed-upon service levels and predicted useful lives facilitates determination of least life-cycle costs for these assets. This information can then be used to provide for capital planning, to minimize the effect on sewer rates.

Fiscal Impact
Project may be incorporated into Cleanwater Program. Actual need will depend on Cleanwater Program availability. This project is funded by Wastewater Management Fund revenues.

Project Description/Scope/Purpose
This project is to update the data system used by, and to provide handheld data entry devices to, the Environmental Service Department’s Environmental Compliance Inspectors and Lab/Field Technicians in the Regulatory Programs Division. This project will aim to integrate (or replace) the various databases currently used to manage inspection data, and enable inspection and sampling activities by inspectors to be recorded on a hand-held data entry device and uploaded to a database for further tracking, trend analysis, regulatory reporting, work scheduling, and enforcement actions. It will achieve greater efficiencies by making inspection data more readily available, reducing the possibility of human error in transcribing paper inspection reports to a database, minimizing the possibility of lost or misplaced paper files, and reducing the time needed to gather and store inspection data. Current methods are error-prone, slow, and consume staff time that could be better used for other critical tasks.

Project Evaluation and Analysis
Other water quality inspection programs in Bay Area cities already use such equipment and databases to handle their work.

Newer and expanded requirements for various inspection types and business types, such as stormwater treatment features in new and redevelopment; trash reduction ; mercury management practices at dental practices; as well as long established commercial, and significant industrial user programs, have led to a growing inventory of businesses inspected with dynamic needs for reporting to regulatory agencies. This project will help the program keep pace with the increased needs.

Fiscal Impact
Operating costs are for software licensing and equipment replacement. These costs were derived from expenditures for a different hand-held data device project for Maintenance and Operations staff. Replacement is estimated at eight-year intervals but will be evaluated and updated when appropriate hardware/software platforms have been identified.

Project Description/Scope/Purpose
The Lawrence Expressway Sanitary Sewer trunk main (main) is a critical pipe for carrying sewage from the southern and eastern portions of the City and the Rancho Rinconada area of Cupertino to the Water Pollution Control Plant. The main, which was originally installed in 1963, has been impacted by corrosive sewer gases over the years and has reached the end of its useful life expectancy of 50 years.

A condition assessment and preliminary design report for the main was completed in 2016 which identified several defects, access issues, areas requiring heavy cleaning, and degraded portions of the sewer trunk main pipeline. Bids for construction of an Initial Project to address these immediate needs were received in late 2020. In addition, the 2015 Wastewater Master Plan indicates that a capacity increase is needed along this alignment, or along an adjacent corridor. An analysis to determine the preferred alternative is underway and a new project to fund the capacity improvements will be proposed once conceptual costs are known. If a capacity increase along Lawrence Expressway is preferred, this increase will likely involve installation of a parallel sewer rather than upsizing the existing sewer. For this reason, rehabilitation of the existing sewer is warranted.

Project Evaluation and Analysis
Not funding this project could result in a complete failure of the Lawrence Sanitary Sewer Trunk Main piping system. Due to the high volume of sewage that the line conveys, a failure of this magnitude could be an environmental disaster and the Lawrence Expressway roadway could potentially develop a sinkhole if the City takes no action.

Fiscal Impact
This project is funded by Wastewater Management Fund revenues.

Project Description/Scope/Purpose
The City’s sanitary sewer system includes 13 locations with inverted siphons, which are pipes that dip under obstructions such as roadways and creeks. Over time, these low points accumulate sediment and grease and must occasionally be removed. In 2019, this project funded cleaning and inspection of some of the siphons. In early 2023, the City advertised a construction contract to clean and inspect the siphons that still need work. This project will fund this effort, and will allow for periodic cleaning and inspection in future years.

Project Evaluation and Analysis
Siphons must be cleaned and inspected to ensure proper function, and to prevent blockages due to sediment, grease, and potential damage of existing pipes. Such blockages may result in sewer overflows in nearby roadways or creeks, which may trigger regulatory fines.

Fiscal Impact
This project is funded by the Wastewater Management Fund.

Project Description/Scope/Purpose
This project funds the maintenance and rehabilitation of the current secondary treatment equipment at the Water Pollution Control Plant (WPCP) pending the construction of new secondary treatment facilities in ten to twelve years.

Rehabilitation may include: incorporation of chemical dosing facilities; upgrades to the existing polymer feed system, pump overhauls, and replacements. Cost estimates for these elements are based on vendor quotes, benchmarks with other agencies, and preliminary estimates from engineering consultants. Specification development and implementation planning will require additional engineering efforts which will form the first phase of this project.

Project Evaluation and Analysis
Project implementation is phased over several years to allow for continued operation of the WPCP and sequencing of the processes and equipment to ensure adequate processing capacity for the incoming wastewater. Polymer system upgrades started in FY 2019/20 and will continue into FY 2023/24. This schedule may change due to WPCP conditions and evaluation results.

Project Description/Scope/Purpose
The Power Generation Facility (PGF) at the Water Pollution Control Plant (WPCP) was built in 1997 with the gas management/controls system to generate power using three fuel sources: landfill gas, digester gas, and natural gas. Stricter emission requirements imposed by the California Air Resources Board and the Bay Area Air Quality Management District combined with the declining quality of landfill gas continue to raise the cost of operating the engines, requiring frequent tune-ups and additional gas pre-treatment.

Over the last few years there were several instances when the engines "dropped" off the power distribution grid, resulting in immediate demand for PG&E, who provides back-up power. The instantaneous load results in significant cost increases in the WPCP utility bill, estimated at $80,000 to $100,000 per year in demand charges and peak day pricing. Additionally, legislation and regulation are currently being considered to further reduce emissions associated with combustion power generation for the WPCP engine types.

The scope of this project includes ongoing rebuilds and preventative measures to ensure reliable engine operations and adherence to emission regulations. A new PGF is being contemplated as part of the WPCP rebuild and is anticipated to be on- line by 2028.

Project Evaluation and Analysis
PGF is currently scheduled to be replaced in the 4 - 5 years. This project is proposed to complete more rigorous re-builds of the engines and replacement of the associated components to ensure compliance with the air regulations as well as reliable operations until the new facility is completed.

The obsolete engine control system on the No. 2 PGF was upgraded in 2018, the No 1 PGF engine control system was replaced in early 2022 in conjunction with the major overhaul.

The digester gas dryer, and PGF engine gas flowmeters are also on schedule for replacement in FY 2022/23.

Project Description/Scope/Purpose
This project funds the rehabilitation of the tertiary treatment process at the Water Pollution Control Plant (WPCP). Master Planning for the WPCP rebuild has identified that the tertiary process at the facility will most likely not change in technology.

However, electrical and instrumentation upgrades will be needed in the future to integrate with the new treatment plant along with rehabilitation of existing equipment.

In the interim, some extensive rehabilitation is necessary to maintain operations of the WPCP and compliance with the City's NPDES permit. The tertiary process of the WPCP consists of four Dual Media Filters (DMF), which are large tanks filled with sand and anthracite coal that provide filtration, and disinfection facilities consisting of chlorine contact tanks. Most rehabilitation will be completed by the pending Existing Plant Rehabilitation Project.

This Project will address items not included in the Existing Plant Rehabilitation Project.

Project Evaluation and Analysis
Project implementation is phased over several years to allow for continued operation of the WPCP and sequencing of the processes and equipment to ensure adequate processing capacity for the incoming wastewater. Mechanical, electrical and control system evaluations were conducted, and the final condition assessment report was used to develop and design the Existing Plant Rehabilitation Project. Due to the Existing Plant Rehabilitation Project Budget constraints some identified areas in the condition assessment report were excluded from the project. Project items identified that may be addressed in this project are the Filtered Water Pump overhauls, coatings and DMF galley filtered water flowmeter replacements and DMF media replacements. Pond effluent flow bypass pipping is essential for the operation of the tertiary system. Funds may also be used for modifications of the emergency pond effluent bypass piping installation.

Fiscal Impact
The project is funded by Wastewater Management Fund revenues. Existing implementation funds are proposed to support rehabilitation or replacement of the tertiary process equipment through FY 2024/25 in alignment with the Plant Rehabilitation.

Project Description/Scope/Purpose
This project funds a study that will identify sources of direct Inflow and Infiltration (I&I) of ground water into the sanitary sewer collection system. I&I contributes to additional hydraulic loading in the collection system which increases treatment costs as well as reduces design collection system conveyance capacity. I&I causes poor recycled water quality. The City is currently producing recycled water with a higher than average salinity content, which is affecting the overall quality and usability of recycled water for certain applications. The current sewage treatment process used by the City is not effective at removing salinity.

Several neighboring cities have been successful at reducing salinity and treatment costs by identifying and correcting sources of groundwater I&I. The first phase of this project will conduct a feasibility study to identify sanitary sewer pipe segments where I&I is occurring. Conductivity monitors are deployed at strategic locations in the collection system where I&I is suspected. The information collected by conductivity meters identifies pipe segments where high salinity is occurring, which is generally indicative of an I&I source. Pipe segments are typically recommended to be rehabilitated to eliminate the I&I source. The most common method of pipe rehabilitation to correct I&I sources is cured-in-place pipe lining (CIPP), but replacement and/or spot repairs may be necessary as well. This study may result in additional funding needs based on study findings.

Project Evaluation and Analysis
This project will identify sources of groundwater I&I, which may be affecting the quality of recycled water produced by the WPCP.

The sanitary sewer collection system and the WPCP stand to benefit from this project by improving recycled water quality and reducing treatment costs associated with additional hydraulic loading. The reliability of the collection should also be improved as capacity in the system will be increased with the reduction of the additional hydraulic loading.

Failing to undertake this project would result in increased treatment costs to improve recycled water quality. It could also result in illicit sewage discharges from the sanitary sewer collection system due to hydraulic overloading which would have adverse public health and environmental impacts, as well as result in regulatory penalties and fines.

Fiscal Impact
This project is funded by the Wastewater Management Fund. This project is necessary to minimize treatment costs and improve recycled water quality. FY 2022/23 project funding will be used to see the project to completion in FY 2024/25.

Project Description/Scope/Purpose
CFD is mandated by the State's stormwater permit to maintain twenty stormwater biotreatment basins, which require rehabilitation of infrastructure every ten years. This includes the replacement of plants and drainage materials, with an estimated cost of $75,000. While the City has allocated funds for a portion of the improvements to take place in FY 22-23, this project seeks to secure funding for the remaining work needed to ensure compliance with the permit requirements for all basins.

Project Evaluation and Analysis
The City's current landscape vendor for CFD No.3 has provided a quote (attached) for recommended improvements, which includes the replacement of plants and drainage materials, at an estimated cost of $75,000. We propose to utilize the allocated funds in FY 22-23 to initiate the project and aim to secure additional funding for FY 2023/24 to complete the remaining work for all basins.

Fiscal Impact
This project is funded through an annual property assessment of homes located within CFD No. 3. Project expenditure is limited to funds collected under CFD No 3.

Project Description/Scope/Purpose
Water Pollution Control Plant (WPCP) Master Plan is completed and the facilities will be reconstructed over the next 10 to 15 years, existing buildings and supporting structures need major rehabilitation to make them last until the new structures are built.

These various support facilities will require updates to heating, ventilating, and air conditioning (HVAC) related equipment upgrades, Plant service air compressor replacements, power generation building roof repair and fan replacements, sodium bisulfite pump station canopy, painting of various structures and equipment.

The proposed budget includes funding for plant wide facility repairs including roof and heating/cooling systems, building upgrades and a canopy at the Sodium Bisulfite pump station. The sodium bisulfite pump station is subject to the elements, water intrusion into the pump controls and the electrical system has caused pump failures. Temporary corrective measures are in place until a permanent structure can be installed. Due to the pump station location the installation of the new canopy will follow the completion of the planned flood wall which is anticipated to be completed by FY 2025/26.

Project Evaluation and Analysis
The WPCP has several buildings and facilities that are in varying states of decay, as the buildings are over 40+ years old and are in need of replacement. Also, the new administration building and laboratory that was initially proposed is currently unfunded and repairs will need to be done until there is a new building.

Fiscal Impact
This project will be funded by Wastewater Management Fund revenues.

Project Description/Scope/Purpose
Solids processing facilities at the Water Pollution Control Plant (WPCP) consist of four digesters and associated piping and pumping systems along with the gas collection systems. The digested solids were processed further on tile beds for further drying and hauled off site for disposal. The solids drying operation has been transferred to a contracted operation to allow for the area of the tile beds to be prepared for the construction of the new headworks and primary treatment facilities. This project allows for modifications to the solids conveyance systems, supernatant drainage system and the pumping station improvements needed to allow for the transition of the drying operation to a contracted operation. Further, the project allows for digestor repairs and other modifications required to operate the solids handling facilities safely and efficiently.

Project Evaluation and Analysis
Recent projects involve repairs to the digesters that are part of the solids handling facilities. These include repairs to the digesters dome cover and the seals to prevent gas leaks and adding improved hatches for safe access and digester gas system conveyance upgrades.

Fiscal Impact
This project will be funded by Wastewater Management Fund revenues.

Project Description/Scope/Purpose
This project provides for wastewater utility surface access adjustments in order to preserve consistent height with surfaces and roadways. Wastewater utility surface access features include manholes, clean out and inspection covers, drainage inlets, and other wastewater infrastructure surface access points. Wastewater utility surface access points can be impacted by street rehabilitation activities and other excavation projects.

Paving rehabilitation projects generally have an effect on the elevation of the surfaces of existing utility access assets. This project provides funding for the adjustment of utility access infrastructure with paving rehabilitation with both contracted and in- house projects. Additionally, the City performs utility access surface restoration as a result of public inquiry, unsafe condition, other misalignment, or in conjunction with other operational activities. This project will also provide funding for the purchase of new wastewater utility surface access covers that are worn out, damaged, structurally compromised, or those that are not able to be reinstalled.

Project Evaluation and Analysis
This project will ensure that wastewater utility surface access assets are maintained and restored in a manner that is consistent with City standards. The project will also ensure that wastewater utility surface access assets are able to be restored to a condition that allows for the smooth travel of vehicles and bicycles on roadways and other surfaces where utility access covers are not uniform.

Fiscal Impact
This project is funded by the Wastewater Management Fund.

Project Description/Scope/Purpose
The Water Pollution Control Plant (WPCP) Oxidation Pond Levee Rehabilitation project provides funding for site assessments, weed abatement, levee repairs, levee maintenance, levee road maintenance, and other levee related work to keep this critical asset sound for the next 20 years. These levees form the containment, flow paths, and pumping structures that make-up the WPCP Secondary Treatment Process. The levee roads allow the public to enjoy access to the lower south bay slough systems while keeping the Bay and Storm water from entering the WPCP Secondary Treatment process.

The oxidation ponds are contained by approximately eight miles of earthen levees formed by clamshell dredging and compaction. The WPCP levee system has not had any significant rehabilitation since the ponds were commissioned in the late 1960s. The network of levees has become significantly overgrown vegetation and significant erosion has occured along the levee roads. The proposed weed abatement will remove all vegetation (estimated at approximately eight acres) from the levees and manage regrowth overtime. Also, this project will also rehabilitate sections of the levee roads which have become significantly worn and eroded.

Project Evaluation and Analysis
A City-wide condition assessment study was conducted of City structures. WPCP oxidation pond levees were included in this study. Areas along the levees were identified for repair in this condition assessment study. The information in the condition assessment was used to create the WPCP Pond Levee Operations and Maintenance manual. Rehabilitation projects may include, but are not limited to, structurally reinforcing the levees, repairing breaches and cracks, removing weeds, and raising subsided sections of the levees. On-call engineering firms will provide construction management support and outside contractors will perform the repair work. Segments with the highest likelihood of impact will be given priority.

Additional funding needed to complete repairs to South, West and completion of the East pond levees. Cost estimates have now been refined based on actual construction costs of one section of levee repair. Costs estimates for the West levee repair range from $650,00 to $1,820,033 depending on repair option chosen. The cost estimate to repair the remaining section of the East levee is $4.5M given on page 6 of the HDR Engineers design memo. A rough cost estimate of $4M for the repair of the south levee is based on in house repairs per Operations and Maintenance manual.

Fiscal Impact
The initial cost estimate indicated up to $27 million would be needed for all repairs identified in the engineering report and the most urgent repair work is budgeted and underway. Additional funding would be required to address all repairs. The twenty-year budget is based on oxidation pond weed abatement costs and in house levee repair projections.

Project Description/Scope/Purpose
As the City adopts the Master Plan to rebuild the Water Pollution Control Plant, there is growing interest from corporations, wholesale water agencies and retailers in the region to partner with the City in expanding its recycled water program and potentially develop potable reuse projects as well. The recent drought has further emphasized this need for reuse projects. There are several complex technical issues and regulatory and financial impacts to be evaluated, and concepts developed in partnership with other adjacent cities and the water agencies such as Valley Water further the planning efforts related to potable re-use. This project could also be utilized in extending technical assistance to companies interested in using recycled water. The technical expertise and resources needed for these evaluations are beyond the scope of City staff and would further need to align with the Program Management Consultant team's efforts in implementing the Master Plan. Therefore, this project is needed to support the planning efforts related to potable and non-potable reuse and respond to requests for technical information and review of ideas and concepts presented by regional partners related to re-use.

In the past, the WPCP produced Recycled Water (RW) with relative ease. Title 22 of CA Code of Regulations describes guidelines for production and use (RW is also known as Title 22 water). The main requirement for Title 22 water is to have a solids content of <2 NTU. However, in the past 2 years, the plant has had a difficult time producing <2 NTU water. In fact, our RW production has stopped for the last year. The primary reason for this is due to the water quality changing in our pond system. In the last couple of years, the ponds have been propagating a single cell, sub-micron blue-green algae species in high quantities. This algae and other solids are typically taken out in our Air Flotation Tanks (AFTs) after the wastewater returns to the plant from the ponds, however, due to the small size of this unique algae, the AFTs have not been able to take it out. As a result, it ends up in our Dual Media Filters (DMFs) and tends to choke it. Because of this, the efficiency of the DMFs has reduced resulting in producing poor quality water that is not suitable for RW. We would like to run a filter study pilot (example, disk filters, cloth filters and the like) that can accommodate any type of algae and still produce <2 NTU water. This would allow us to produce RW continuously.

Project Evaluation and Analysis
It is important for the City to produce RW, especially during drought years, which has been the case for the past few years. This project will look at different ways of producing RW including using new equipment. Before installing new equipment, they need to be pilot tested to affirm the equipment works for our wastewater. Equipment vendors have small pilot plants they rent for short periods of time to test wastewater. This type of a pilot study allows us to confirm the process works for our wastewater before we make a decision to buy equipment for the plant, which is a sizable expense and effort. Currently there are multiple vendors approved to produce RW. These technologies are mostly disk and cloth filters. This project will plan to run pilot studies with this equipment with multiple vendors side by side so that they could competitively bid in the event the City decides to implement the technology.

Fiscal Impact
This project is funded by the Wastewater Management Fund and the Water Supply and Distribution Fund.

Project Description/Scope/Purpose
This project provides funding for an update to the master plan for the sanitary sewer system and storm drain system. The project will assess the hydraulics, system models, physical condition, and separation and maintenance of the collection systems, and will recommend improvements to provide adequate hydraulic capacity and improve the reliability of the collection system. It will include an analysis of the financial impacts of the recommendations and scheduling, and may inform revisions to Project 825331 - Replacement, Rehabilitation, and Repair of Sewer Pipes.

The City provides sanitary sewer services to residents and businesses within the City as well as a portion of Cupertino known as Rancho Rinconada. This study is needed to define the capital projects that will be necessary to replace aging infrastructure and to identify any capacity-increasing projects that may be needed as a result of in-fill development. This type of plan is considered to be a best management practice for ensuring that the wastewater collection system can continue to provide reliable service.

A sewer master plan including hydraulic models for the storm and sanitary systems was completed in FY 2014/15. This project will update the models and analyze and develop alternatives for future wastewater capital projects and funding.

Project Evaluation and Analysis
This project is necessary to maintain existing essential infrastructure of the Wastewater Utility that excludes the WPCP. The information developed as a result of this study can allow the City to require developers to pay for capacity increases or for rehabilitation of existing sewers. This project will also fulfill several regulatory requirements for wastewater asset management.

Fiscal Impact
This project is funded by Wastewater Management Fund revenues. When completed, the master planning effort will likely result in new project recommendations that will be proposed in future capital improvements budgets.

Project Description/Scope/Purpose
The City of Sunnyvale Water Pollution Control Plant (WPCP) provides wastewater treatment for the residents and businesses within the city. The Primary treatment process removes solids in the influent. Those separated solids are collected and sent to the anaerobic digestion treatment process.

Over time, the WPCP Digesters accumulate debris. This debris impedes the operation of digester equipment and decreases the solids reduction efficiency. Digester Cleaning is required at regular intervals to ensure that the city's anaerobic digesters have sufficient treatment capacity and to protect digester equipment from damage. During the cleaning process, Digesters are taken out of service, and a contractor is hired to break up and remove the fixed debris and other inorganic material trapped in the digesters. The contractor also dewaters trapped biosolids during the cleaning process and hauls them off-site for proper disposal.

Project Evaluation and Analysis
Task-specific contractor equipment and specially trained staff are required to handle digester cleaning safely and efficiently. The need to clean the anaerobic digesters increased when the WPCP upgraded and rehabilitated all four of the Plant's anaerobic digesters. These upgrades allow for better mixing, reduced solids, and increased digester gas production, all positive benefits.

However, the trade-off with better mixing systems is more frequent cleaning. The current cleaning interval will be extended post- completion of the New Headworks Project, part of the Sunnyvale Cleanwater Program, and all the digesters have been cleaned at least once post-startup of the New Headworks and Primary Treatment facilities. The mechanical systems that are part of the new Headworks will remove most of the problematic material that currently ends up inside the digesters, decreasing the required cleaning frequency.

Fiscal Impact
This project is funded by the Wastewater Management Fund revenues. Cost projections are based on the current contract for the required service, and future costs are based on the market rate for the same service. Under the current contract and the potential reduction in need when the new headworks treatment process comes online, a reduction of 1.2 million dollars over the 20-year horizon is anticipated.

Project Description/Scope/Purpose
This project scope funds the implementation of a web-based operations and maintenance (O&M) manual for the Water Pollution Control Plant (WPCP) that is similar to or the same as other document management systems the City uses. This project is intended to replace the limited, narrative-based paper O&M manual. The WPCP Electronic Operations and Maintenance Manual (EOM) project aimed to develop a living document, repository, and seamless interface. Regulations require O&M information to be readily available for training and as a response reference to keep plant personnel safe, the process compliant, and for systems to run as efficiently as possible.

When systems fail, the WPCP O&M team requires rapid access to accurate technical information. The new system is intended to reduce the time spent searching through folders, binders, and other documents that may contain obsolete information. This project also facilitates the capture and transition of institutional O&M knowledge from departing employees. The WPCP Electronic Operations and Maintenance Manual project also includes the procurement, installation, and implementation of an electronic logbook, another regulatory requirement, to increase operational efficiency further and simplify historical review of process changes and system troubleshooting.

Project Evaluation and Analysis
The City's WPCP Cleanwater program is replacing old wastewater treatment systems and updating existing ones. The information needed to operate and maintain these systems reliably must include an intuitive method of storing and retrieving any WPCP documentation. Changes in nearly every future process require operations and maintenance team members (that are turning over as well) to have access to a centralized, user-friendly interface to view standard operating procedures (SOPs), record drawings, equipment information, process control descriptions, operating manuals, regulatory information, and historical data from the Laboratory Information Management System (LIMS), Enterprise Asset Management System/Computerized Maintenance Management System (EAMS/CMMS) and Supervisory Control and Data Acquisition (SCADA). An electronic O&M manual would also facilitate training new employees, refreshing the knowledge of existing staff, and function as an up-to-date reference for a wide variety of information. The City’s NPDES permit requires the wastewater treatment plant to furnish and maintain accurate O&M manuals, SOPs, and record drawings. These documents are necessary for the reliable operation, maintenance, and troubleshooting of treatment and support systems.

Fiscal Impact
This project is funded by the Wastewater Management Fund revenues. Costs are based on the amount of effort required to fully populate a digital platform, the transition from one system to another, and to procure an online logbook based on market availability.

Project Description/Scope/Purpose
A sanitary sewer system hydraulic model is an essential tool for determining where existing sewer pipes may need to be upsized to accommodate existing and future development. The City completed an initial model in 2015, and then a much more detailed model in 2022. During both efforts, temporary flow meters installed during relatively dry winters were not able to record increases in sewer flows that happen during rain storms. This project will allow for installation of flow meters during upcoming rainy seasons, and allow for updates and recalibration of the hydraulic model based upon the new data.

Project Evaluation and Analysis
The 2022 hydraulic model update identified sewer capacity improvement projects. However, the necessary sizes of larger pipes, and the timing of when the projects should be implemented, are uncertain due to lack of wet weather flow data. Upon successful collection of wet weather data, these parameters will be better understood, and staff will be able to proceed with efficient project implementation.

Fiscal Impact
Proposed budget in two consecutive fiscal years allows for attempted collection of wet weather flow data in the first year that, if unsuccessful due to dry weather, can be attempted again the following year. After successful data collection, funding allows for the engineering effort of updating the model and providing a summary report.

Project Description/Scope/Purpose
Sewer capacity projects previously identified in the 2015 Wastewater Collection System Master Plan and budgeted under this capital number have been superseded by the projects listed below, as identified by a 2022 Wastewater sewer capacity study.

Design of CIP-1, CIP-2, and CIP-3 are scheduled for FY 2025-26, FY 2027-28, and 2031-32 respectively. Wet weather flow monitoring data collected in early 2023 may result in changes to the proposed scopes, budgets, and timing of these projects.

CIP 1: S. Mary Ave from Cambridge Ave to north of W. Evelyn Drive. Upsize existing 6”-12” pipe with 10”-15” pipe.

CIP-2: New Arques Lift Station: Install new force main, wet well, and pump system.

CIP-3: Along E. California Ave., Roosevelt Ave., and E. Arques Ave., upsize existing 21” pipe with 24”-30” pipe.

Project Evaluation and Analysis
Many existing sewer lines are not large enough to carry existing peak wet weather flows. Upsizing of sewer lines is necessary to reliably convey the wastewater to the Water Pollution Control Plant, prevent sewer overflows and accommodate future growth.

Fiscal Impact
This project is funded by the Wastewater Management Fund.

Project Description/Scope/Purpose
This project funds the transition of Laboratory protocols and practices to address new standards for Laboratory Certification, adopted by the State of California. ESD's Lab provides water quality testing for both drinking water and wastewater, and certification is required for both services. Implementation of the new standards is required to be in place by December 2023.

Extension of the project is proposed to include support for validating implementation and evaluating ongoing workload impacts based on actual implementation.

Project Evaluation and Analysis
The State has completed a multi-year process to adopt more stringent standards for water quality laboratory certification. The State's update more closely mirrors national standards, which include much more stringent requirements for quality control and operational documentation. This project provides consultant support and limited temporary staffing to address transition to the new standard.

Implementing the new certification standards requires significant additional work to maintain a robust quality control program including much more documentation. The addition of a Limited Term position provides more stable staffing to support the implementation as the department evaluates how needs may change with implementation experience.

Fiscal Impact
This project is funded by Wastewater Management Fund and Water Supply and Distribution Fund revenues. Additional funding proposed is for 50% of a Limited Term Lab/Field Tech for FY 2023/24 through FY 2025/26. The other half of the funding for this position is available in the Operating Budget for ESD Program 14705 Environmental Laboratory.

The ongoing funding in the Lab's Operating Budget has been used for temporary agency staffing. In the last 18 months, it has been very difficult to get and retain (for even the 6 months) temp agency staffing and the Limited Term approach will provide some valuable reprieve from the inherent turn-over and recent impracticability of 6-month assignments.

Project Description/Scope/Purpose
On September 20, 2016 Council approved the Peery Park Specific Plan. The plan calls for developers to pay $3.12/net new square foot of development to be put towards wastewater infrastructure improvements to accommodate increased development in the Peery Park area.

The project is scheduled to begin design in FY 2024-25, with construction beginning in FY 2026-27. Wet weather flow monitoring data collected in early 2023 may result in proposed changes to the scope, budget, and timing of this project.

Project Evaluation and Analysis
Based upon the wastewater study performed, a number of larger diameter sewer pipes need to be upsized to serve the increased development anticipated in the Peery Park area. The Peery Park wastewater capacity improvement fees will cover design and construction costs associated with increasing size of the larger (10" and larger) sanitary sewer pipelines, per the study. Each development project will be responsible for performing a sanitary sewer analysis to determine if the sewer mains fronting their project need to be upsized; costs for the analysis and subsequent upsizing will be the developer's responsibility.

Fiscal Impact
Funding for this project is provided by fees assessed to developers within the Peery Park Specific Plan area. It is anticipated that some wastewater capacity improvements may be performed by the developer. However, should a development project not do the construction, the fees would be collected for the City to perform a capital project. Funding shown is the maximum amount anticipated, should all developers pay instead of constructing the wastewater infrastructure.

Project Description/Scope/Purpose
All costs are associated with active litigation regarding alleged non-compliance with the Stormwater Permit and potential leakage from the sanitary sewer collection system into the stormwater system causing or contributing to exceedances of water quality objectives for bacteria in local waterways. The case could possibly move to the trial phase in January 2023.

Project Evaluation and Analysis
In February 2020, Baykeeper filed suit against the City of Sunnyvale and the City of Mountain View alleging violations of the Clean Water Act/non-compliance with the Stormwater Permit due to bacteria discharges above water quality standards. Plaintiff alleges the potential that such discharges are the result of leakage from the sanitary sewer collection system into the storm drainage system as described above. This project funds outside litigations costs due to the complex nature of the case.

Fiscal Impact
Funding included in this project covers attorney fees. If the case settles before trial, the full amount of $750,000 will not be necessary. In the event of settlement, a separate project would be established to fund commitments under the settlement agreement.

Project Description/Scope/Purpose
The City of Sunnyvale provides sewer service to a subdivision of 91 homes in the City of Cupertino and Valley Water requested the City remove the existing sewer pipe bridge due to a Calabazas Creek improvement project. This project will include removing the sewer bridge and diverting sewage flow from 91 homes to Cupertino Sanitary District (CuSD) pipe system, and diversion back into City of Sunnyvale pipe system. An executed agreement between the City of Sunnyvale and Cupertino Sanitation District outlines the responsibilities for the project.

Project Evaluation and Analysis
This project was prompted by Valley Water to remove an existing City sewer pipe bridge from Calabazas Creek serving 91 City homes. The City needed to find an alternative routing of the sewage flow away from the bridge. The City negotiated an agreement with Cupertino Sanitary District to divert the flow from the 91 homes into their system. This project will find the diversion of the flow, for the City to receive the flow back at a different location. Other options considered would have still required the sewage flow to cross the Creek and were deemed cost-prohibitive.

Fiscal Impact
The cost to remove the bridge and make appropriate improvements is estimated at $115,000. The agreement with CuSD will not affect the level of service provided to the residents of the 91 homes and the transfer will be seamless with no interruption in service. The City will continue to respond to service calls and perform any facility improvement within the subdivision.

Project Description/Scope/Purpose
The State Water Resources Control Board, which regulates sanitary sewer systems issued a statewide Order 2022-0103-DWQ on December 8, 2022 updating sanitary sewer systems regulations. The City of Sunnyvale as an operator of a wastewater collections system is required to prepare a Sewer System Management Plan (SSMP) by 2026 and every five years thereafter.

Project Evaluation and Analysis
The SSMP is aimed at reducing sanitary sewer overflows and should includes elements demonstrating how the City constructs, manages, operates and maintains its sanitary sewer system.

Fiscal Impact
$100,000 will fund the services of a consultant to prepare the SSMP. This project is funded by Wastewater utility rates. Rates are set to cover the cost of operations and capital projects required to maintain the system and provide Wastewater service.

Project Description/Scope/Purpose
The Digester No.3 Improvement project will repair the failed interior and exterior annular tank lid seal. This seal prevents methane gas which is collected at the top of the tank from leaking out to atmosphere. In order to increase the life of the epoxy seal the tank lid skirt which extends into the tank will be lengthened to prevent exposure to the methane gas. In addition, a new larger side hatch will be installed similar to the Digester 1 and 2. The removal of the tank lid will facilitate the hatch installation.

The larger hatch will facilitate safer entries into the tank by plant staff and contractors.

Project Evaluation and Analysis
This project was initially developed for construction under the plant Maintenance program. However, due to the scale of the project it has been determined that a Public Works project is needed to complete the project. The design and construction estimate has been completed by an outside engineering firm. This digester is currently operating under a very constrained operating level due to the failed seal.

Fiscal Impact
This project is funded by Wastewater utility rates. Rates are set to cover the cost of operations and capital projects required to maintain the system and provide Wastewater service.

Project Description/Scope/Purpose
This project consists of the construction of a new permanent chemical storage tank facility consisting of one chemical storage tank with chemical dosing pump skid. The permanent chemical storage facility is to be constructed to accommodate all health and safety requirements. Chemical treatment is needed to treat pond effluent water With changing pond water quality in the future, the plant needs to have the capacity to store chemicals to treat this pond effluent.

Project Evaluation and Analysis
About six months ago, temporary chemical tanks were installed to test the effectiveness of multiple chemical regimes to mitigate the pond algae. In the last couple of years, the ponds have been propagating a single cell, sub-micron blue-green algae species in high quantities. This algae and other solids are typically taken out in our Air Flotation Tanks (AFTs) after the wastewater returns to the plant from the ponds, however, due to the small size of this unique algae, the AFTs have not been able to take it out this algae. This has resulted in the plant’s ability to meet its National Pollutant Discharge Elimination System (NPDES) permit limits difficult. In fact, the plant violated its NPDES permit limit 5 times this past summer. Each violation can result in a $3,000 penalty. The new chemical regimes have proven to be effective, however, a permanent tank storage facility is needed to store the chemicals. This includes a permanent concrete pad, one chemical storage tank and dosing station. The current temporary chemical storage tanks have an engineered useful life of about 2 years in the current construction.

Fiscal Impact
This project is funded by Wastewater utility rates. Rates are set to cover the cost of operations and capital projects required to maintain the system and provide Wastewater service.

Project Description/Scope/Purpose
This project will fund the abandonment of a small section of Sunnyvale's sewer line. In the 1950s, the City of Sunnyvale entered an agreement with developers that allowed the Rancho Rinconada sewer system to be tied into a City sewer main. This sewer main would serve a mostly residential area that did not have direct access to a sewer collection system. The sewer system was constructed to meet the City's standards and allowed the City to collect fees from homeowners and businesses to reimburse the City for the costs of providing ongoing sewer service. In January 2021, the City reached out to the City of San Jose to investigate a change that was made to the existing sewer main. This change included a new manhole which plugged Sunnyvale's pipeline.

A new sewer pipe was constructed which diverted the flow into the City of San Jose's sewer system. After several meetings, both cities came to an agreement where the City of San Jose will pay the City of Sunnyvale $800,000 to return the system to its previous condition. This change in systems will also require the abandonment of a small section of Sunnyvale's sewer line that is south of the new manhole.

Project Evaluation and Analysis
This project is required to properly abandon a section of sewer line that is no longer in use. This process is a regulatory requirement and needed to complete the transfer of a portion of the City's sewer system outside of the City to the City of San José.

Fiscal Impact
This project is funded by a settlement payment in the amount of $800,000 received as part of the agreement to transfer the system.
