Hello Esteemed City Council Members,
Thank you for your commitment and service to our community! I am requesting the City Council to take action on a rental property at 1612 Grant Street. It appears the home is vacant and for rent however the property has been”personal trash” sitting in the front yard for over 14 days now.

This can present uninvited issues to our neighborhood (animals, insects, odor) and as a decades long owner resident on Grant St, it’s very important we keep up a clean safe environment - especially being so close to Calistoga High. We have to set an example for the young Calistogans as they walk to school. (Additionally, this is quite embarrassing to allow this type of degradation and disrespect towards our town’s environment and residents.)
I am providing photos taken today (4/10/26) from the sidewalk on Grant Street.

Thank you for your support and look forward to your response and keeping Calistoga clean and safe! Item #3.1.

CAUTION: This email originated from outside of the organization. Do not click links or open attachments unless you recognize the sender and know the content is safe.

April 20, 2026
Mayor, Vice Mayor, Council members,
I would like the City of Calistoga to reconsider its contract with Flock Safety. Here are just a few reasons. This affects all Calistogans.
 This contract is automatically renewed every year. This means there is no public input, no council members input, no vote what’s so ever.
 This contract is costing Calistoga $17,500.00 every year.  The six cameras around Calistoga, (Petrified Forest Road, Hwy 29, Hwy 128, Lake County Hwy, Silverado Trail and Myrtledale Rd.) have taken 126,087 images this past month alone.  Calistoga PD Policy states no facial recognition, people or gender is captured. This is false. With new AI technology, Flock Safety cameras are taking images of the drivers and passengers.  Calistoga PD Policy states that this data is not sold to third parties. False, Flock Safety does sell this data to third parties.
 Calistoga PD Policy states the data retention is for 30 days. False, Flocks Safety keeps this data for up to a year or more and allows other agencies outside Calistoga and California access to this data.  Calistoga PD preaches transparency. Freedom of Information Act requests have failed to show:
o Who is in charge of the program?
o Who is trained, what training has been completed, documentation of that training? o Which agencies have requested these images and the reason for these searches?  Many agencies and municipalities are cancelling their contracts with Flock Safety due to privacy concerns, public safety concerns, misuse of data, contract terms, illegal access from out of state agencies, and unwarranted surveillance.
 Currently, there are dozens of lawsuits against Flock Safety.  These cameras are a serious risk to our privacy and civil liberties.

Here are a few websites about Flock Safety and its cameras.  https://deflock.org

STAFF REPORT
To: Honorable Mayor and City Council
From: Jed Matcham, Fire Chief
Meeting: City Council Regular Meeting - Apr 21 2026
Subject: Replacement of LUCAS Chest Compression Devices DESCRIPTION:

Consider adopting a Resolution Authorizing the Purchase of Two Mechanical CPR Devices RECOMMENDATION:

Consider Adopting the Resolution
SUMMARY:

The Fire Department currently utilizes LUCAS Chest Compression System mechanical CPR devices in frontline service to support cardiac arrest resuscitation. These devices have been deployed for several years and have exceeded their recommended service life. The manufacturer has indicated that the current units will no longer be supported, limiting the department’s ability to maintain and repair them moving forward.

Despite their age, these devices have proven to be a critical piece of life-saving equipment and have contributed to multiple successful cardiac arrest resuscitations (“field saves”) over the course of their service.

Replacement of these units is necessary to ensure continued reliability, compatibility with current standards, and ongoing manufacturer support.

ANALYSIS:

The Fire Department is proposing the replacement of its existing units with two new LUCAS 3.1 mechanical CPR devices. Mechanical CPR devices provide consistent, high-quality chest compressions in accordance with current resuscitation guidelines and are widely recognized as a best practice in modern EMS systems.

Key benefits include:
 Consistent compression depth and rate, improving CPR quality  Reduced firefighter fatigue during extended incidents  Improved provider safety during transport by minimizing unsecured activity in the patient compartment
 Ability for personnel to focus on life support interventions  Increased operational efficiency during prolonged or complex incidents The attached quote (Quote #11246697, dated January 29, 2026) includes:
 Two LUCAS 3.1 devices with accessories and training: $40,584.88 Item #6.4.

Page 24 of 117 ends

 One desktop battery charger: $987.66
 Trade-in credit for two existing devices: -$8,000.00
 Three-year ProCare service coverage (following first year warranty): $6,561.60  Sales tax and shipping: $3,870.46
Total cost: $43,264.60
The trade-in program allows the City to receive value from the existing units while transitioning to updated equipment.

Approval of this purchase will ensure the Fire Department maintains the ability to deliver uninterrupted, high-quality CPR during cardiac arrest incidents. Given the demonstrated history of successful resuscitations using the current devices, replacing these units directly supports improved patient outcomes and firefighter safety.

Failure to replace the devices may result in loss of capability due to equipment failure and lack of manufacturer support.

FINANCIAL IMPACT:

The total project cost is $43,264.60, including equipment, four years of service/maintenance coverage, tax, and shipping.

City of Calistoga

STAFF REPORT
To: Honorable Mayor and City Council
From: Rena Lariz, Human Resources Manager
Meeting: City Council Regular Meeting - Apr 21 2026
Subject: Salary Schedule Adjustment
DESCRIPTION:

Consider adopting a resolution to update the City Manager's salary, adjust the salary range for the Community Services Officer classification and add the Accounting Technician Classification.

RECOMMENDATION:

Consider Adopting the Resolution
SUMMARY:

The proposed resolution updates the City Manager salary to align with the Acting City Manager’s employment agreement approved by Council on February 17, 2026.

Additionally, the Community Services Officer (CSO) salary range is being adjusted following updates to the job description, including the removal of the POST certification requirement and dispatch-related duties, to better reflect the current scope of work and maintain alignment with comparable agencies.

The resolution also establishes a new Accounting Technician classification, as identified by Finance, to appropriately categorize accounting-related functions. These updates are administrative in nature and are intended to ensure that classifications, job descriptions, and compensation structures remain accurate and aligned with the City’s operational needs.

ANALYSIS:

On February 17, 2026, the City Council approved an employment agreement for the Acting City Manager, Mitchell Celaya. The compensation outlined in that agreement differs from the current City Manager salary schedule; therefore, a technical correction is necessary to ensure the classification reflects the Council-approved salary.

Finance has identified the need to establish a new classification titled Accounting Technician. This action is administrative in nature and is intended to appropriately classify accounting-related duties.

There is no additional fiscal impact associated with this change.

The Community Services Officer job description was recently updated following an evaluation of the City’s staffing model and operational needs. The review determined that CSOs are no longer required to perform dispatch services, and as a result, the POST certification requirement has been removed. In addition, the job description has been updated to incorporate animal control-related services, further aligning the position with current operational needs.

Item #6.5.

Page 30 of 117 ends

Following the change to the Community Services Officer job description, Human Resources conducted an internal salary survey using Council-approved comparable cities. Based on this review, the CSO salary range has been adjusted as necessary to reflect the revised duties of the position. The updated range lowers the salary to align with the current scope of work and ensures consistency with comparable agencies.

STAFF REPORT
To: Honorable Mayor and City Council
From: Derek Rayner, Public Works Director/City Engineer Meeting: City Council Regular Meeting - Apr 21 2026
Subject: Approving the Updated Sewer System Management Plan (SSMP) DESCRIPTION:

Consideration of a Resolution Approving the Updated Sewer System Management Plan for the City of Calistoga.

RECOMMENDATION:

Consider Adopting the Resolution
SUMMARY:

The City’s Sewer System Management Plan (SSMP) was initially developed in 2006 to comply with requirements of a 2005 Order from the San Francisco Regional Water Quality Control Board (Regional Water Board). The SSMP has since been revised several times in order to comply with the State Water Resources Control Board (State Water Board) Statewide General Waste Discharge Requirements for Sanitary Sewer Systems (SSS WDRs), Order No. 2006-0003-DWQ and subsequent amendments.

The 2006 SSS WDRs and 2013 amendments were superseded by Order No. 2022-0013-DWQ, issued on December 6, 2022, and effective June 6, 2023. The 2022 SSS WDR requires updates to the SSMP. Element 6 of the SSMP and the Spill Emergency Response Plan (SERP) have been updated back in May 2023. Elements 1-5 and 7-11 (see list below) have now also been updated to satisfy requirements in the 2022 SSS WDRs and are required to be certified by City Council by May 2, 2026.

ANALYSIS:

SSMPs are required to include the following eleven elements:

1. Introduction and Goals

2. Organization

3. Legal Authority

4. Operation and Maintenance Program

5. Design and Construction Provisions

6. Spill Emergency Response Plan (SERP)

7. Sewer Pipe Blockage Control Program

8. System Evaluation, Capacity Assurance, and Capital
Improvements

9. Monitoring, Measurement, and Program Modifications
Item #6.6.

Page 36 of 117 ends

10. Internal Audits

11. Communication Program
At a minimum, the SSMP is updated every three years (or more often, if needed) with the help of Larry Walker Associates, the City’s consultant for sewer collection and treatment issues. The SSMP is required to be recertified by the City Council by May 2, 2026, and, moving forward, recertified once every six years.

FINANCIAL IMPACT:

The FY25/26 Budget includes funding in Account No. 03-4141 for Contract Services to sufficiently fund compliance with the updated SSMP requirements.

CEQA STATUS:

That the recommended action is not a project under the definitions contained in the Guidelines of the California Environmental Quality Act (CEQA) and is therefore exempt from CEQA.

Sewer System Management Plan Version 10 – April 2026

1. Introduction and Goals
A Sewer System Management Plan (SSMP) is a comprehensive document that describes how public agencies manage and operate their wastewater collection systems. The City of Calistoga (City) SSMP defines the policies, procedures, and practices used to operate and maintain the sanitary sewer system, prevent and respond to sewer spills, and ensure compliance with all applicable regulatory requirements. The SSMP is implemented through coordinated efforts among City departments and includes ongoing staff training, routine field inspections, asset management practices, and evaluations of system performance.

This first element of the SSMP establishes the program’s goals and presents an overview of the applicable regulatory framework, the schedule for SSMP updates, and a summary of the City’s sewer system assets and service area.

1.1 Regulatory Context
The City’s SSMP was initially developed in 2006 to comply with requirements of a 2005 Order from the San Francisco Regional Water Quality Control Board (Regional Water Board). The SSMP was since revised several times in order to comply with the State Water Resources Control Board (State Water Board) Statewide General Waste Discharge Requirements for Sanitary Sewer Systems (SSS WDR), Order No. 2006-0003-DWQ and subsequent amendments.

The 2006 SSS WDR and 2013 amendments were superseded by Order No. 2022-0013- DWQ, issued on December 6, 2022, and effective June 6, 2023. In May 2023, Element 6 of the SSMP and the associated Spill Emergency Response Plan (SERP) were revised to comply with 2022 SSS WDR. This latest version of the document, SSMP Version 10, has been further revised such that Elements 1-5 and 7-11 also satisfy requirements in the 2022 SSS WDR. This latest version of the SSMP also incorporates recommendations from the City’s most recent internal SSMP audit performed in November 2025.

1.2 Sewer System Management Plan Update Schedule
Per the 2022 SSS WDR, an SSMP must be self-audited at least once every three (3) years and updated every six (6) years from the original adoption date by the Enrollee’s governing board. The schedule for auditing and updating this SSMP from 2025 through 2032 is provided in Table 1. Upon certification by City Council, the City’s Legally Responsible Official (LRO) will upload the SSMP to the California Integrated Water Quality System (CIWQS) database, which is the State Water Board’s regulatory and water quality information management system.

The CIWQS database is used to collect and store an enrollee’s facility and organizational information and details of all spills which occur from an enrollee’s sanitary sewer system (spill reports).

1.3 SSMP Goals
The City of Calistoga mission statement is as follows:
“We are dedicated to serving the needs and desires of our citizens by:
• Maintaining a safe and secure environment and high quality of life. • Preserving and enhancing the community’s unique beauty and character. • Managing our resources efficiently, effectively and equitable. • Recognizing the value and benefits of our diversity.
• Achieving long-term fiscal stability and self-sufficiency. • Encouraging full public participation and ongoing communication. • Strengthening partnerships with the private, non-profit and other public sectors for the cohesive and innovative delivery of government services.” The Public Works Department includes the Sewer Collection Division and the Wastewater Treatment Division. The Public Works Department goals include the proper management, operation, and maintenance of all parts of the wastewater collection system, maintaining adequate capacity to convey peak flows, minimizing the frequency and volume of spills, and mitigating the impact of spills.

The Sewer Collection Division maintains four sewer lift stations in the City and all of the City’s existing sewer mains and recycled water mains, making repairs and replacements when necessary and installing new sewer mains and recycled water mains when required.

The goal of this Division is to continue to maintain the City’s sewer collection system to ensure no disruption of service or inconvenience to the City’s residents.

The Wastewater Treatment Division operates and maintains the Dunaweal Wastewater Treatment Plant (WWTP) and disposal system. The WWTP processes the City’s sewage, producing a high quality effluent that can be discharged to the Napa River and/or recycled for irrigation purposes. The goal of this Division is to continue to provide the necessary treatment and disposal processes for the City of Calistoga’s residents in the most environmentally sensitive and cost effective manner possible.

1.3 Sewer System Asset Overview
The City’s sanitary sewer collection system conveys wastewater for the area within the city limits to the Dunaweal Wastewater Treatment Plant (WWTP). The WWTP has an average Item #6.6.

Page 43 of 117 ends

City of Calistoga Page 1-3
Sewer System Management Plan Version 10 – April 2026
dry weather flow design capacity of 0.84 million gallons per day (MGD) and can treat up to

4.0 MGD during wet weather flow events.

City’s sewer collection system serves a population of approximately 5,200. Inputs to the sewer system are mainly domestic in origin and include residences, hotels, and geothermal spas. However, there are also several restaurants, a micro-brewery, and two mineral water bottling companies that discharge to the sanitary sewer system. Out of a total of 1,370 sewer connections, approximately 88% are residential, and 12% are commercial.

The City has an up-to-date map of its collection system. The current version was prepared in 2002 and is updated yearly whenever a new sewer line or structure is added. The City employs asset management software – SewerGEMS and web-based ArcGIS. There are approximately 16 miles of sewer lines, 250 manholes, and 4 lift stations within the City’s collection system. The City usually experiences two or fewer small (less than 150 gallons) collection system spills per year. The number of spills is decreasing as older pipelines are replaced and repairs are made.

4. Operation and Maintenance Program

4.1 Updated Map of Sanitary Sewer System
The City of Calistoga maintains up-to-date maps of wastewater collection system facilities.

Maps are currently available in ArcGIS. Access can also be provided by request. These maps include:
o All gravity line segments
o Manholes
o Pumping facilities
o Pressure pipes and valves
o Applicable stormwater conveyance facilities

4.2 Preventive Operation and Maintenance Activities
The City schedules regular maintenance of certain sewer lines that are known to have problems with oil and grease on a quarterly and semi-annual basis. Foothill Blvd., Cedar Street, sewer line from the Rancho De sewer lift station easterly to North Oak Street, and Grant Street in the vicinity of the Fairgrounds are cleaned every six months. Lincoln Avenue, Washington Street, and Fair Way are cleaned quarterly. All other sewer lines are cleaned on an annual basis. This maintenance includes using a hydro machine to flush and clean the sewer lines as noted below.

The City owns two sewer hydro machines with cutter attachments that are used to clean and flush the sewer lines. The goal of the maintenance program is to clean the entire sewer system each year. In addition, certain areas of the City require more frequent cleaning, as often as once a month. The main causes of flow obstruction are roots and fats, oil and grease (FOG). The hydro machines work effectively to eliminate these obstructions.

Hydro
The hydro cleans grit and grease accumulated from
sewer mains with water pressure, scouring the inside
of the pipes. The hydro is used primarily for cleaning
sewer lines that have the highest potential for
blockage, mostly due to grease being discharged into
the sewer lines. These areas are described as "hot
spots".

Once a week, the Maintenance Technicians also make observations at manholes, inspect the lift stations, time the pumps, and test the emergency power systems. Approximately 20 to 30 manholes are checked each week. A log sheet is completed for each manhole, where observations on flow, pipe condition, and infiltration are recorded. A sample lift station inspection report and a sample manhole inspection sheet are presented in the attachments to this chapter. Department personnel estimate that most potential flow problems are prevented by this weekly inspection. City staff are qualified and regular trainings are provided to personnel in sewer maintenance and operations, discussed further in Section 6.5.

Sewer System Management Plan Version 10 – April 2026
Structural deficiencies are noted when making routine inspections and during the hydro cleaning process. If a structural problem is suspected, cameras are brought in to identify the specific problem and location. Excavation and repairs are then undertaken when warranted.

The City maintains a large, extensive inventory of replacement parts and equipment. The City must keep a large inventory because it is located at least an hour away from the major plumbing/equipment distributors. In fact, City staff has not been caught short during an emergency repair situation in at least 20 years.

The City currently distributes an information sheet for plumbers and contractors discussing how spills can be prevented when sewer laterals are being repaired as well as steps to take during new construction to prevent future problems. (See attached information sheet in Appendix A).

In 2025, the City initiated a project with a consultant to camera all sewer mains 75-years and older. Where repairs are deemed necessary, the assessment will provide preliminary design (10%), cost estimates, and financial strategy to support design completion and construction for repairs or replacement. As of early 2026, CCTV’ing has been completed and the consultant continues to work on utility replacement/rehabilitation designs. They will also be planning financial strategies to identify funding for completion of the recommended repairs.

This project will continue into 2026, and repairs are expected to continue over the next several years.

4.3 Training
The Maintenance Superintendent arranges for his staff to attend seminars regarding spill prevention as well as providing in-house weekly training sessions related to a wide variety of issues, including sewer line maintenance and cleaning. As of March 2026, the Maintenance Superintendent and the Senior Maintenance Technician are in the process of developing a training that covers all of the updated requirements from the 2022 SSS WDR. The training will also cover protocol for overflow events. The training is scheduled to be completed by the end of April. Contractors are required to be appropriately trained before conducting work for the City and must demonstrate proof of training or certification as needed. Certifications for classes/seminars attended are maintained by the Administrative Assistant.

4.4 Equipment Inventory
The City of Calistoga owns seven (7) backhoes and loaders as well as other equipment needed for sewer line repair. In addition, the City maintains a list of Contractors that are available in emergencies with equipment and personnel (see attached list in Appendix B).

The City maintains a current inventory of sewer system equipment and critical spare parts to ensure rapid response to emergencies. The following equipment and replacement components are kept in stock:
• Sewer hydrojet/hydro-flushing unit(s)
• Sewer camera/CCTV inspection equipment
• Couplers
• Pipe fittings (various sizes)

5.1 Updated Design Criteria and Construction Standards and Specifications
The City of Calistoga Municipal Code Chapter 16.16, Design and Improvement Standards, , requires that the design, construction, installation, repair, and rehabilitation of system infrastructure components, including pipelines, pump stations, and other appurtenances, shall comply with the following standards and specifications: all water mains shall be constructed of C900 PVC CL200 or Ductile Iron Pipe CL200 and shall be no less than eight inches in diameter, except that six-inch diameter mains may be permitted by the Public Works Department in areas where fire hydrants are not required and the water main will not be extended for future use; all existing and proposed utilities within the subdivision shall be placed underground in accordance with the provisions of the Calistoga Municipal Code; and all private sewer systems are subject to the approval of the County Department of Environmental Health, with a letter from the Health Officer setting forth findings and recommendations on the subdivision layout required prior to City approval of any subdivision proposing to utilize a private sewer disposal system.

The City of Calistoga Municipal Code Chapter 16.18, Construction of Improvements, requires that all streets, drainage facilities, water distribution and fire protection facilities, sanitary sewer facilities and other required improvements shall be constructed in accordance with the provisions of this chapter and with the following specifications, as applicable: the Public works Standard Specifications of the City of Santa Rosa, Caltrans Standard Specifications, the American Water Works Association, Board of Fire Underwriters.

All improvement plans must be prepared and signed by a registered civil engineer and must be approved by the City Engineer prior to construction.

5.2 Procedures and Standards
Newly constructed, repaired, or rehabilitated sewer collection facilities are tested using standardized procedures to ensure system integrity and performance. Gravity pipelines are typically tested using air or water (exfiltration/infiltration) testing to confirm there are no leaks, while CCTV inspections are conducted to verify proper installation, alignment, and the absence of defects. Force mains are pressure-tested to check for leaks and structural soundness. All lines are cleaned prior to testing, and any deficiencies identified during testing or inspection are repaired and retested before the facilities are accepted and placed into service.

All improvements are subject to inspection by the City per Municipal Code Chapter

16.18.040. Inspections shall include testing by a certified testing firm to ensure all facilities meet the requirements of the specifications for that particular item. If it is determined that construction of any particular improvement is deficient, a deficiency list will be prepared by the inspector and transmitted to the contractor. Upon completion of all corrections or additional work outlined in the deficiency list, the contractor is required to request a final inspection by the Director of Public Works.

6. Spill Emergency Response Plan
A copy of the City’s Spill Emergency Response Plan (SERP) can be found in Appendix C.

The SERP protocols are summarized below.

6.1 Notification
This section summarizes information on how the City is to be notified of a spill through a complaint or a report. Additionally, this section includes the chain of communication leading up to the response to the spill.

The City provides emergency on-call service 24-hours a day, every day of the year. Maps of storm drains are kept on hand, and are accessible by the City. The City will clear all plugged sewer main lines. If the problem is in the property owner’s lateral, the City crew will inform them of the situation and may turn off the customer’s water until the plug has been cleared.

The Calistoga Municipal Code defines the property owner’s lateral as the pipe from the structure or dwelling to the point where it enters the City’s main line. It is the property owner’s responsibility for operation, maintenance, and repair of the lateral and building plumbing. Anyone wishing to report a spill should contact the Department of Public Works , the after hours number will reach the Calistoga Police Department:

Address: 414 Washington Street, Calistoga CA 94515
Hours: 8:00 a.m. - 4:30 p.m.

Phone: 707-942-2828
After Hours Phone: 707-942-2810
Fax: 707-942-9472
When spills are reported, the Maintenance Technicians are contacted by cell phone or home phone and dispatched to visit the spill site. The Maintenance Technicians rotate their schedules to ensure that someone is on-call 24 hours per day, 7 days per week. The City has contacts at Napa County Public Works, who can be reached in case spill response coordination with the County is necessary.

6.2 Response
Once a spill is verified, water is turned off in that line or re-routed to a downstream sewer manhole until the spill has been contained and cleaned up, and the problem has been solved.

The Maintenance Technician calls for assistance if needed, estimates the volume spilled, and reports the spill to the Maintenance Superintendent. Spill cleanup is conducted immediately which involves spill containment, prevention of discharge to nearby waterways, use of absorbent materials or vacuums (depending on the spilled volume), and air drying of wet surfaces. No chlorine or lime is used for disinfection per guidelines circulated by the Napa County Department of Environmental Management and the State of California Department of Fish and Game.

Item #6.6.

Page 53 of 117 ends

City of Calistoga Page 6-2
Sewer System Management Plan Version 10 – April 2026
An automatic telephone alarm system monitors all collection system pump stations, treatment plant units, and irrigation pump station for spills or water quality. A plant operator and collection system personnel are on call 7 days a week. The alarm system pages the operator or a backup operator in the event of any alarms at the treatment and disposal facility. The system will also call the Calistoga Police Department in the event the alarm is not responded to. The collection system pump stations have high level and power failure alarms, which call the Police Department for dispatching of collection system personnel.

At the Wastewater Treatment Plant, inadequately treated waste will automatically bypass the waste back into the treatment plant or equalization pond system. A storm water pump system collects all rain water and any plant overflow water and pumps it back to the flow equalization storage pond for treatment processing. The City also has a 6-inch portable diesel fully automatic wastewater pump for emergency use which is capable of pumping in excess of 1 mgd as well as several 4-inch portable gas pumps with sufficient hose to bypass wastewater around any collection system or treatment plant unit.

6.3 Reporting
The Public Works Director and Maintenance Superintendent are responsible for completing, or overseeing the completion of regulatory reporting associated with spills.

If 1,000 gallons or more reach surface waters or groundwater, the Public Works Director or Maintenance Superintendent notifies the California Office of Emergency Services (CalOES) within 2 hours from the time of becoming aware of the spill.

The Public Works Director or his/her designee is also responsible for completing, or overseeing the completion of the SSO Spill Form and of the CIWQS online reporting (http://ciwqs.waterboards.ca.gov). Depending on the spill classification, CIWQS reporting procedures are as follows:

Category 1 (Spills to Surface Waters):
 Submit draft report within 3 business days of becoming aware of a Category 1 spill.
 Finalize report and certify within 15 calendar days of the end of the spill.  If more than 50,000 gallons reached surface waters, an SSO Technical Report will be developed and submitted within 45 calendar days of the end of the spill.

Category 2 (Spills of 1,000 gallons or Greater That Do Not Discharge to Surface Waters):
 Submit draft report within 3 business days of becoming aware of a Category 2 spill.
 Finalize report and certify within 15 calendar days of the end of the spill.

Category 3 (Spills of Equal or Greater than 50 Gallons and Less than 1,000 Gallons That Does Not Discharge to Surface Waters):

Item #6.6.

Page 54 of 117 ends

City of Calistoga Page 6-3

 Submit certified report within 30 calendar days of the end of month in which the spill occurred.

Category 4 (Spills Less Than 50 Gallons That Do Not Discharge to Surface Waters):
 Submit the number of Category 4 spills and the total volume from Category 4 spills into the CIWQS online SSO Database http://ciwqs.waterboards.ca.gov within 30 calendar days after the end of the month in which the SSOs occurred.  Upload and certify a report with details from all Category 4 spills from throughout the calendar year by February 1st of the following year.

6.4 Impact Mitigation
When a spill results in release of sewage into the street, the following procedures are used to remove the wastewater and clean the affected area:

1. Collect wastewater utilizing absorbent material, or install wastewater containment device(s).

2. Pump contained wastewater into the downstream sanitary sewer manhole.

Additionally, signage is placed at the location of the spill to alert the public and minimize potential exposure.

If a spill results in release of sewage into a surface water, the following procedures are used to minimize negative impact on the affected area:

1. Immediately stop additional flows from entering the waterway.

2. Clear the plugged sewer main.

3. If 50,000 or more gallons reach surface water, sampling of the body of water is mandatory. Sampling procedures are included in the Water Quality Monitoring Program which can be found as an attachment to the SERP. At the direction of the Director of Public Works, sampling of lower volume spills may also be performed.

6.5 Training
Formal training related to the Emergency Response Plan is scheduled annually. All employees are required to attend and a log of attendees is kept. Other informal training sessions take place throughout the year as needed. These informal sessions are not logged.

7. Sewer Pipe Blockage Control Program
Chapter 13.08, titled Sewer Service, of the Municipal Code decrees that it is unlawful to dispose of any materials capable of causing obstruction with the proper operation of the sewer system. This includes oils, grease, rags, and any miscellaneous debris capable of causing blockages, interfering with pump operations, or with proper function of any other sewer system components. Efforts to reduce and control the discharge of pipe blocking substances to the sewer are described in the following sections.

7.1 Identification & Sewer Cleaning
During routine sewer cleaning and in response to plugged lines, the City has identified areas or line segments of the wastewater collection system that experience intrusion of roots and/or accumulation of fats, oil, and grease (FOG) and have established a prioritized cleaning schedule for each area. Hydro jetting is conducted to clean of the pipes and prevent blockages. Two sewer mains within the downtown corridor have been identified that need more frequent cleaning due to FOG buildup. The City flushes those lines every month to two months to prevent flow restrictions. Problem areas change over time and are not due to a consistent or single cause. For example, problem areas appear to occur in areas with:
• High density housing or multiple families residing in single family homes • Mobile home residential areas
• Commercial buildings

7.2 Source Control
Higher horsepower pumps have been employed in order to reduce blockages, particularly of rags and wipes. As part of an effort to address oil and grease issues in the City of Calistoga’s wastewater, a program to educate residents regarding proper handling of used cooking oil was developed. The general message of the outreach campaign is that residents should dispose of used cooking oil in the trash, using absorbent materials (e.g., paper towels), rather than down the drain. The activities included in the City’s outreach program are described below.

Identify Problem Areas
City collection system staff were consulted to identify areas within the City where collection system upsets were most likely to occur. Call-out records were reviewed to obtain a more complete picture of collection system problem areas. The collection system was characterized for locations having a history of sewer system upsets. This characterization included a determination of whether the upsets were associated with residential or commercial activities. Residential areas were further characterized to determine if the area consisted of low density (i.e., single family homes mostly) or high density (i.e., apartment complexes) housing. Institutional facilities that serve food (i.e., convalescent hospitals, schools) were also identified in the problem areas.

Outreach Materials
Based on the information obtained regarding the residential problem areas and experiences of other communities, outreach materials were developed containing simple messages regarding proper handling of used cooking oil and grease. These materials included collateral materials Item #6.6.

Page 56 of 117 ends

City of Calistoga Page 7-2
Sewer System Management Plan Version 10 – April 2026
such as pot holders, magnets, flyers and door hangers (see examples of materials in the attachments to this chapter). A FOG educational spot also runs on the City’s Public Educational Government Channel (broadcasting on Channel 28 of Calistoga cable TV subscribers) and the City continues to provide updated information via the City’s website. To support the commercial sector, the City distributes outreach packets to restaurants that include Best Management Practices (BMP) implementation guides, lists of grease haulers, example service contracts, and maintenance record-keeping templates. Furthermore, the City supports regional efforts through the Bay Area Pollution Prevention Group (BAPPG), which expanded its reach in 2025 with a website available in 14 languages and digital campaigns, such as Mobile Ad Messenger GIFs, targeting cooking enthusiasts during the holiday season.

Conduct Outreach
The outreach materials developed can be distributed in many ways, including a booth at the Napa County Fair, local newspapers and publications, and door hangers.

If the problem areas contain schools, group facilities or apartment complexes, it may be possible to work with their staff to implement practices that would aid in the education process. Kitchen staff from schools or group facilities with large kitchens will be educated on proper oil and grease handling practices. Schools will be asked to distribute information for students to bring home. Apartment complex managers could be asked to provide outreach materials to new tenants and to assist with general distribution of materials. They could also be asked to track grease problems that occur within the complex. This tracking may be useful for evaluating program progress. In commercial areas, if a grease build-up is observed in a sewer main or if wipes cause issues the City hands out educational pamphlets to upstream businesses and residents. Additionally, in 2026, City staff plan to re-establish regular meetings with the Napa County Environmental Health Division to discuss FOG management during routine restaurant inspections by the County.

Program Evaluation
Program evaluation will be conducted periodically to determine if the program is meeting its goals of reducing oil and grease discharged from residential areas. Mobile home facilities will be asked to track grease problems within their plumbing system. Collection system upsets will be tracked to determine if a decrease in collection system upsets has occurred.

Finally, a survey card will be distributed to determine the level of awareness of oil and grease disposal issues. The evaluation results will be used to determine any future steps needed to reduce oil and grease in the collection system.

7.3 Facility Inspection
The initial focus of the City’s FOG program was on residential sources of oils and grease, with the necessity for inspection of local food service establishments also being evaluated.

An agreement was approved for food services establishments to be inspected on an annual basis by the Napa County Department of Environmental Management as part of the NPDES Stormwater Pollution Prevention Program. Education related to the disposal of fats, oil and grease is part of these inspections.

Item #6.6.

7.4 Legal Authority
The City of Calistoga’s sewer use ordinance is located in Chapter 13.08 of the Calistoga Municipal Code, available at: https://ecode360.com/47982570 . As specified in Sections 425 and 430; grease traps, interceptors, and/or sand traps must be provided at all restaurants, carwashes, breweries, mud baths, and bottling plants. The owner of the business must keep maintenance records that include: when the trap/interceptor was cleaned, how much grease was removed, and how much and when any pretreatment was used. Licensed grease/oil recycling firms must be utilized for disposal, and disposal invoices must be retained for inspection.

Other pipe blocking substances such as solids or viscous substances that are including, but not limited to rags and other debris are detailed in Chapter 13.08, Section 320 of the Municipal Code.

Enforcement of the ordinance is addressed in Article XI, Enforcement, of the Sewer Use Ordinance. Every violation is subject to a fine of not less than $50 or more than $1,000 per day. Corrections must be made within 7 days of notice or the City will make the repairs and bill its expenses to the property owner. The City also has discretion to disconnect any user that does not comply with the regulations.

7.5 Disposal
During cleaning of sewer lines, FOG waste is removed and placed in a dumpster at the Calistoga Wastewater Treatment Plant headworks facility where it is disposed of through the treatment facility waste disposal contract. Napa County provides information for proper disposal of FOG generated through residential uses on its website at https://naparecycling.com/guide/cooking-grease-oil. The website includes information for proper disposal of both solid and liquid FOG substances.

8. System Evaluation, Capacity Assurance and Capital
Improvements

8.1 System Evaluation and Capacity Assurance Plan
The Capital Improvement Plan includes measures for evaluating the system and ensuring capacity. Current capital improvements include reconditioning of manholes, a sewer system assessment and master plan, sewer trunkline replacement, a sewer lateral replacement program, and inflow and infiltration improvements.

The City is in the process of developing a Sewer Master Plan and is working on an initial sewer system model that includes conditions of manholes and age of pipes. A dryweather capacity modeling is complete and hydraulic modeling for wet weather flows is in planning stages. The model findings will provide information on available capacity in the City’s sewersheds and help prioritize I&I repairs, if needed.

The City is not aware of collection system assets vulnerable to climate change impacts, aside from potential capacity issues related to increased I&I during rain events with increased intensity.

8.2 Capacity Assessment and Design Criteria
Currently, capacity studies are performed in isolated areas, during development planning.

The City has recently completed a dry-weather capacity modeling; hydraulic modeling for wet weather flows is in planning stages.

8.3 Prioritization of Corrective Action
The City and District have identified the need for additional flow monitoring, condition assessment, and hydraulic modeling for wet weather flows to provide a basis for the Sewer System Master Plan and for additional short- and long-term CIP schedules. The findings from condition assessments and capacity assessments are used to prioritize corrective actions, consistent with the 2022 SSS WDR. This prioritization considers both the severity of the consequences associated with potential spills and the specific conditions under which hydraulic deficiencies occur.

Existing capacity concerns are prioritized over future potential concerns, as they present a more immediate risk of system failure and discharge. Among these concerns, those that occur during average dry weather flow conditions are assigned the highest priority, as they indicate a consistent and ongoing capacity limitation. Capacity issues observed under peak dry weather conditions are given a moderate priority, while those occurring only under peak wet weather conditions are considered a lower priority, reflecting their association with less frequent, storm events.

This approach ensures that the most critical and spill-prone deficiencies are addressed first, effectively reducing the risk of spills and protecting water quality and public health.

8.4 Capital Improvement Plan
The City maintains a budget document, breaking down allocated money for capital improvement projects posted on the City’s website at:
https://www.calistogaca.gov/Government/City-Budgets
The City approves their annual budgets in June for the following fiscal year. The current operations and maintenance budget for the wastewater collection system is $4.5 million.

The annual Wastewater Enterprise Funds budget for the sewer utility provides financial support for sewer administration, construction and maintenance, sewer services, and sewer CIP projects. Wastewater Treatment and Operations are funded through sewer user rates. New rates were implemented on March 1, 2024, and there are additional planned annual rate adjustments between 2025 and 2028. The new rates include anticipated Operation and Maintenance increases as well as necessary capital that is forecast to be completed by 2028.

The City completed a field inspection survey of the collection system manholes to document existing conditions. The City has purchased software and created an initial model that includes conditions of manholes and age of pipes. The City will develop a prioritized shortterm and long-term capital improvements from the model estimates for the next ten-year Capital Improvement Plan. In 2025, the City initiated a project with a consultant to camera all sewer mains 75-years and older. Where repairs are deemed necessary, the assessment will provide preliminary design (10%), cost estimates, and financial strategy to support design completion and construction for repairs or replacement. As of early 2026, CCTV’ing has been completed and the consultant continues to work on utility replacement/rehabilitation designs. They will also be planning financial strategies to identify funding for completion of the recommended repairs. This project will continue into 2026, and repairs and repairs are expected to continue over the next several years.

Project Schedules

9. Monitoring, Measurement, and Program Modifications

9.1 Adaptive Management Plan
Overview
The intention of section is to monitor the effectiveness of each SSMP element and update and modify SSMP elements to keep them current, accurate, and available for audit as appropriate. This section describes the processes used to monitor Plan implementation, measure performance, and modify activities based on findings and results.

Record Keeping and Documentation
The City maintains records of all activities related to Plan implementation, including inspection findings, maintenance records, audit results, and SSO reports. This information is used to establish and prioritize appropriate Plan activities. Audit findings are documented to support ongoing evaluation of program effectiveness and to identify areas requiring improvement.

Monitoring Implementation and Measuring Effectiveness
One way to track the effectiveness of each SSMP element is to use performance indicators.

Performance indicators will be used during the audit process to determine any deficiencies in the SSMP. These metrics are reviewed regularly by staff responsible for SSMP implementation to ensure that each element of the SSMP is being implemented as intended and is achieving its objectives. Examples of performance indicators that will be used to assess the SSMP include:
• Number of spills over the past 12 months
• Spills by cause (roots, grease, debris, etc.)
Assessing Preventive Operation and Maintenance Activities The success of preventive operation and maintenance activities is assessed through routine review of maintenance records, inspection data, and system performance. This assessment includes evaluating if the preventive maintenance program in place are adequate to reduce the risk of pipe blockages and spills.

Updating Plan Procedures and Activities
Plan procedures and activities are reviewed and updated on a regular basis, and as needed, based on the results of monitoring, performance evaluations, and audit findings.

Spill Trends
The City identifies and tracks spill trends to support proactive management of the sewer system. This information is used to direct preventative maintenance efforts and measure the overall effectiveness of the SSMP. As shown in Figure 2, the City has maintained a relatively low number of SSOs since 2009, with no more than two spills occurring in any given year.

Notably, no SSOs were reported between 2017 and 2022, reflecting the effectiveness of the City's preventive maintenance program during that period. As shown in Figure 3, spill volumes were generally minor throughout most of the reporting period, with the exception of 2023, which saw a significant spike of approximately 2,000 gallons due to damage or breakage to Item #6.6.

Sewer System Management Plan Version 10 – April 2026
the sewer line — the largest recorded volume in the reporting period and categorized as "other" in Figure 4. Prior to 2023, smaller spill events were attributed to grease, roots, and debris. The increase in SSO frequency observed in 2023 and 2024, combined with an increase in spill volume, highlights the importance of continued collection system monitoring, targeted maintenance, and the City's ongoing grease control and root intrusion management efforts.

7. Sewer Pipe Blockage Control Program
The City continues to identify and clean sections of the sewer system that are subject to sewer pipe blockages. The City continues to distribute materials regarding source control activities to educate local businesses about FOG control. The outreach materials are distributed in many ways, including a booth at the Napa County Fair, local newspapers and publications, and door hangers. Program evaluation is conducted periodically to determine if the program is meeting its goals of reducing oil and grease discharged from residential areas. The focus of the City’s FOG program is on residential sources of oils and grease. Food service establishments are now being inspected by the Napa County Department of Environmental Management for proper disposal of oil and grease. This section was updated in Version 10 of the SSMP to address The City’s efforts to reduce other pipe-blocking substances, such as debris and rags, in addition to FOG.

8. System Evaluation, Capacity Assurance and Capital Improvements In Version 10 of the SSMP, this section has been renamed to System Evaluation, Capacity Assurance, and Capital Improvements in accordance with the 2022 SSS WDR requirements.

The section was also expanded and updated to incorporate the new 2022 SSS WDR requirements pertaining to System Evaluation and Condition Assessment, Capacity Assessment and Design Criteria, as well as the prioritization of corrective actions. It has also has been updated to include more details on the City’s Capital Improvement Plan (CIP) for wastewater.

The City of Calistoga Municipal Code Chapter 16, Construction of Improvements requires that all streets, drainage facilities, water distribution and fire protection facilities, sanitary sewer facilities and other required improvements shall be constructed in accordance with outlined provisions of this chapter.

9. Monitoring, Measurement and Program Modifications
The section was updated to include an Adaptive Management Plan.

10. Internal Audits
The City completed an internal SSMP Audit in October 2025. The section was updated to include the new SSMP Audit frequency.

11. Communication Program
The section was updated to note that the SSMP is published online and to include procedures for communication with the public in the events of a spill that prompts closures of public areas

10. Internal Audits
The City plans to complete a review of the SSMP every three years to evaluate its effectiveness and to identify any deficiencies and steps to correct them. Within six months after the end of the required three year audit period, the Legally Responsible Official submits an audit report into the online CIWQS Sanitary Sewer System Database. The most recent audit was completed in October 2025. Revisions based on the audit’s recommendation were incorporated in Version 9 of the SSMP (updated May 2026).

11. Communication Program
The City maintains a website (https://www.calistogaca.gov/Home) to inform the public about City activities. The City’s website is an effective communication channel for providing alerts and news to the public. The main page of the website provides important announcements, agendas and minutes for City Council meetings, and other key information for City residents.

The City publishes the SSMP on the Public Works Department page of the City website. The SSMP is certified by the City Council during a public city council meeting once every six years. The SSMP is also made available on the City’s website. The City also uses the website to notify the public of important upcoming activities related to sewer system management, its development, and implementation, and performance.

In the event of a spill resulting in the closure of public areas, the City will publish such information the website as well as through signage in the affected areas. Other communication channels such as press releases or posting on social media would be considered and may be used, on a case by case basis.

The City does not need have any tributary or satellite collection systems; there is no need to establish communication protocols with any such agencies.

Outreach to Plumbers and Sewer Contractors
Item #6.6.

Page 69 of 117 ends

Plumbers & Sewer Contractors:

Your Actions Can Prevent
Sanitary Sewer Overflows!
What are Sanitary Sewer Overflows or SSOs?
SSOs discharge untreated or partially treated human and industrial waste, debris and disease-causing organisms
from the sanitary sewer onto the ground near and into
homes and potentially into creeks, rivers, lakes or streams.

What are the impacts of SSOs?
SSOs may result in property damage, environmental
damage and/or potential liability to you or your company.

Allowing sewage to discharge to a gutter, storm drain or waterway may subject you to penalties and/or out-of-pocket costs to reimburse cities or public agencies for clean-up efforts and regulatory penalties.

How can you prevent SSOs?
and avoid associated penalties & fines
When clearing plugged sewer laterals:
 Whenever possible, remove root balls, grease
blockages and any other debris; don’t push debris
from the lateral to the sewer main.
 If you can’t prevent a root ball or other debris from entering the sewer main when working in our service
area, please call us at ((707) 942-2828, so we can
work with you (free of charge) to remove the root ball
from the sewer main to prevent blockages further
downstream.
 Use plenty of water to flush lines.
 Don’t open manholes. Hazardous sewer gases from
manholes are odorless, undetectable and can be
deadly. Call us to open manholes for you and please
note that discharge into a publicly-owned manhole
requires a permit. Contact our Public Works
Department at (707) 942-2828, for an application.

When constructing sewer laterals:
 Check your work area. Gravel, backfill material and
test plugs can become lodged in the sewer line and
cause blockages. Make sure no debris is left in the
sewer line before you backfill.
 Avoid offset joints – offset joints make sewer lines
vulnerable to root intrusion & grease accumulation,
cause debris hang-ups and make lines harder to
clean. Properly bed your joints and don’t hammer tap.
 In the Calistoga service area, contact our Permit
Counter for the appropriate construction specs at
(707) 942-2828.

Who Do I Call to Avoid an SSO?
Help us help you…
If you require our free assistance to help clear
root balls, grease blockages and other debris
from a main sewer line to prevent an SSO or
to open a manhole in our service area, please

City of Calistoga – Spill Emergency Response Plan Page 1

1. Authority
The City of Calistoga (City) Spill Emergency Response Plan (SERP) is prepared pursuant to National Pollutant Discharge Elimination System (NPDES) permit requirements and the Sanitary Sewer System Waste Discharge Requirements (WDR) to facilitate proper incident reporting procedures and to ensure that the protection of the environment and the public’s health and safety remains a high priority concern.

2. General
The SERP is designed to ensure that every report of a sewage spill incident is immediately dispatched to the appropriate City personnel for confirmation. Quick response will minimize the effects of the spill with respect to impacts on public health, beneficial uses, and water quality of surface waters and on customer service.

2.1. Objectives
The primary objective of the SERP is to protect public health and the environment, satisfy regulatory agencies and waste discharge permit conditions which address procedures for managing sewer spills, and minimize risk of enforcement actions against the City.

Additional objectives of the SERP are as follows:
• Protect collection system personnel and wastewater treatment plant operators; • Protect the collection system, wastewater treatment facilities, and all appurtenances; and
• Protect private and public property beyond the collection and treatment facilities.

2.2. Organization of Plan
The key elements of the SERP are addressed individually as follows:

Section 3 – Spill Response Procedure
Section 4 – Public Advisory Procedure
Section 5 – Maintenance of SERP
Attachments

3. Spill Response Procedure
The Spill Response Procedure presents a strategy for the City’s Public Works Department to mobilize labor, materials, tools, and equipment to correct or repair any condition, which may cause or contribute to an unpermitted discharge. The plan considers a wide range of potential system failures that could create a spill to surface waters, land, or buildings.

3.1. Receipt of Information Regarding an SSO
A sanitary sewer overflow (SSO or spill) may be detected by City employees or by others. The City is responsible to act based on phone calls received or reports on possible sewage spill from the public wastewater disposal system, and to provide immediate response to investigate and/or
Item #6.6.

Page 78 of 117 ends

City of Calistoga – Spill Emergency Response Plan Page 2 correct reported sewer spill. Generally, telephone calls from the public reporting possible sewer spills are received at the Public Works Department or City offices during normal working hours and the Calistoga Police Department after hours. 1) The telephone operator obtains all relevant information available regarding the spill including:
a. Time and date call was received;
b. Specific location;
c. Description of problem;
d. Time possible spill was noticed by the caller;
e. Caller’s name and phone number;
f. Observations of the caller; and
g. Other relevant information that will enable the Public Works Department crews, to quickly locate, assess and stop the spill.
2) The Public Works Department dispatches sewer maintenance technician to confirm the spill. Until verified, the report of a possible spill will not be referred to as a “sewer spill.” If it determined that 1,000 gallons or more reached or are likely to reach surface waters, the Public Works Department shall provide the information orally to the Governor’s Office of Emergency Services (OES) within 2 hours of confirming the spill. The caller will receive an “OES Control Number.” All spills, regardless of volume will be electronically reported into the California Integrated Water Quality System (CIWQS). The Director of Public Works is responsible for reviewing, updating, and certifying the final CIWQS SSO Reports.

3.2. Dispatch of Sewer Maintenance Technician to Site of Sewer Spill Failure of any element within the public wastewater disposal system that threatens to cause or causes a SSO shall trigger an immediate response to isolate and correct the problem. Personnel and equipment shall be available to respond to any SSO location.

Additional maintenance technicians shall be brought in if extra manpower is needed. 1) Dispatching Maintenance Technicians:
• When the City receives notification of a potential sewer spill, the Public Works Department dispatches maintenance technicians with appropriate resources as required.
2) Maintenance Technician Instructions
• Dispatch maintenance technicians by telephone or radio. Assign appropriate personnel, materials, supplies, and equipment needed. • The telephone operator shall verify that the entire message has been received and acknowledged by the Maintenance Technician who was dispatched. All personnel being dispatched to the site of an SSO proceed immediately to the site of the spill. Any delays or conflicts in assignments shall be reported immediately for resolution.

Item #6.6.

Page 79 of 117 ends

City of Calistoga – Spill Emergency Response Plan Page 3 • Maintenance Technicians shall investigate all reports of SSOs. Whether an SSO was confirmed or not, the responding technician will write what was found and what actions were taken. These reports shall be attached to the Complaint Form.
3) Additional Resources
The Maintenance Superintendent or his designee conveys appropriate requests for additional personnel, material, supplies, and equipment for Maintenance Technician working at the site of a sewer spill.
4) Field Supervision and Inspection
• The Maintenance Superintendent or his designee shall visit the site of the SSO to ensure that provisions of this SERP and other directives are met. • The Maintenance Superintendent or his designee is responsible for verbally notifying regulatory agencies within the specified time and submitting the SSO Report.
5) Coordination with Hazardous Material Response
• Upon arrival at the scene of a SSO, should a suspicious substance (e.g., oil sheen, foamy residue) be found on the ground surface, or should a suspicious odor (e.g., gasoline) not common to the sewer system be detected, the City sewer maintenance crew shall immediately contact the Maintenance Superintendent for guidance before taking further action. • Should the Maintenance Superintendent determine the need to alert the hazardous material response team, the Maintenance Technician shall await the contracted hazardous waste team response.
• Upon arrival of the hazardous material response team, the City sewer Maintenance Technician shall take direction from the person with the lead authority of that team. Only when that authority determines it is safe and appropriate for the City sewer Maintenance Technician to proceed under the SERP with the containment, clean-up activities, and correction.

3.3. Spill Correction, Containment, and Clean-Up
This section describes specific actions to be performed by the City sewer maintenance technician(s) during an SSO. The objectives of these actions are:
• To protect public health, environment and property from sewage spills and restore surrounding area back to normal as soon as possible; • To establish perimeters and control zones with appropriate traffic cones and barricades, vehicles, or use of natural topography (e.g., hills, berms); • To promptly notify Cal OES in cases where 1,000 gallons or more reached or may reach surface waters and provide preliminary spill information and potential impacts;
• To contain the sewer spill to the maximum extent possible including preventing the discharge of sewage into surface waters; and • To minimize the City’s exposure to any regulatory agency penalties and fines.

Item #6.6.

Page 80 of 117 ends

City of Calistoga – Spill Emergency Response Plan Page 4 Under most circumstances, the City can handle all response actions with its own maintenance forces. They have the skills and experience to respond rapidly and in the most appropriate manner. An important issue with respect to an emergency response is to ensure that the temporary actions necessary to divert flows and repair the problem do not produce a problem elsewhere in the system. Circumstances may arise when the City could benefit from the support of private-sector construction assistance. This may be true in the case of large diameter pipes buried to depths requiring sheet piling and dewatering should excavation be required. The City may also choose to use private contractors for open excavation operations that might exceed one day to complete. 1) Responsibilities of City Sewer Maintenance Technician Upon Arrival It is the responsibility of the first person who arrives at the site of a sewer spill to protect the health and safety of the public by mitigating the impact of the spill to the maximum extent possible. Should the spill not be the responsibility of the City, the first responder shall turn the City water off to eliminate the potential for additional discharge. The first responder shall direct the immediate clean-up by the Property Owner. If that clean-up is not completed in a timely manner, City crews will provide for the clean-up and bill the property owner. If there is imminent danger to public health, public or private property, or to the quality of waters of the State, then the first responder takes prudent emergency action until the responsible party assumes responsibility and provides actions.

Upon arrival at an SSO, the City sewer Maintenance Technician performs the following:
• Determines the cause of the spill (e.g., sewer line blockage, pump station mechanical or electrical failure, sewer line break, etc.); • Identifies and requests assistance or additional resources to correct the spill or to assist in determination of its cause;
• Takes immediate steps to stop the spill (e.g., relieves pipeline blockage, manually operates pump station controls, repairs pipe, etc.) Where spills from private property threaten public health and safety (e.g., a spill running off of private property into the public right-of-way) water service to the property will be turned off; and
• Requests additional personnel, materials, supplies, or equipment that will expedite and minimize the impact of the spill.
2) Initial Measures for Containment
Initiate measures to contain the spilling sewage and recover where possible sewage, which has already been discharged, minimizing impact to public health or the environment.
• Determine the immediate destination of the spill, (e.g., storm drain, street curb gutter, body of water, stream bed, groundwater infiltration facility, etc.);
Item #6.6.

Page 81 of 117 ends

City of Calistoga – Spill Emergency Response Plan Page 5 • Identify and request the necessary materials and equipment to contain or isolate the spill, if not readily available; and
• Take immediate steps to contain the spill, (e.g., block or bag storm drains, recover through vacuum truck, divert into downstream manhole, etc.)
3) Additional Measures Under Potentially Prolonged Spill Conditions In the event of a prolonged sewer line blockage or a sewer line collapse, set up a portable by-pass pumping operation around the obstruction. • Take appropriate measures to determine the proper size and number of pumps required to effectively handle the sewage flow.
• Implement continuous or periodic monitoring of the bypass pumping operation as required.
• Address regulatory agency issues in conjunction with emergency repairs. 4) Cleanup
Clean sewer spill sites thoroughly after a spill. No readily identified residue (e.g., sewage solids, papers, rags, plastics, and rubber products) is to remain. • Where practical, thoroughly flush the area and clean of any sewage or wash-down water. Solids and debris are to be flushed, swept, raked, picked-up, and transported for proper disposal.
• Secure the spill area to prevent contact by members of the public until the site has been thoroughly cleaned.
• Where appropriate, disinfect and deodorize the spill site. Ensure that any chemicals used are rinsed, flushed, and pumped out into the vactor truck, such that they are not transported downstream into the river. • Where sewage has resulted in ponding, pump the pond dry and dispose of the residue in accordance with applicable regulations and policies. • Use absorbent materials or vacuums (depending on the spilled volume) and air drying of wet surfaces. No chlorine or lime is used for disinfection per guidelines circulated by the Napa County Department of Environmental Management and the State of California Department of Fish and Game.
• Whenever possible, digital photos should be taken of the area before and after cleanup.
5) Photographs and Visual Monitoring
• Photos have to be time stamped (use timestamp on cameras and/or enable location and time stamp data in digital files)
• Photos are required for the following:
• Spill appearance point(s) – take at least one photo of active spill.

Under prolonged spill conditions, take photos at different times to show potential changes in discharges rates throughout the duration of the spill.
• Spill entry point into the storm drain system
• Location of discharge into the surface water

3.4. SSO Reporting
The Spill Reports in Attachment A contain information which is required to be reported to regulatory agencies. The website for reporting SSOs is:
http://ciwqs.waterboards.ca.gov/. The Maintenance Superintendent or his designee completes the appropriate Spill Report (Short or Long, see Attachment A). The Short Form is to be used when the SSO is less than 1,000 gallons and none of it has reached the surface waters (Category 3 and 4 SSOs). The Long Form is to be used when the SSO is greater than 1,000 gallons or when any volume reaches surface waters (Category 1 and 2 SSOs). In addition, an SSO where 1,000 gallons or more reach surface waters must be reported to the California Office of Emergency Services (CalOES) within 2 hours of becoming aware of the spill.

Reporting instructions are as follows:
 Category 1 SSO - Any spill that reaches surface water

1. If 1,000 gallons or more reach or threaten to reach surface water, call CalOES within in two (2) hours to receive an OES Control Number - (800) 852-7550.

2. For all spills that reach surface waters, regardless of volume:
• Complete the Long Form Report
• Enter data into the CIWQS online SSO Database within 3 business days of becoming aware of the spill http://ciwqs.waterboards.ca.gov • Certify report by Legally Responsible Official within 15 calendar days of SSO end date

A PROJECT MANAGEMENT
A.1 PROJECT ORGANIZATION
This monitoring program will be conducted under the direction of the City of Calistoga (the City) with guidance provided by Larry Walker Associates (LWA). Caltest Analytical Laboratory of Napa (Caltest) will serve as the primary laboratory, but alternatives might be used due to logistics and timing. The Project Contact list is provided in Table 1.

A.2 BACKGROUND
In 2006, the State Water Resources Control Board (State Water Board) adopted Statewide General Waste Discharge Requirements for Sanitary Sewer Systems (SSS WDRs), Order No. 2006-0003-DWQ. The Monitoring and Reporting Program (MRP) established monitoring, record keeping, reporting, and public notification requirements.

On September 9, 2013, Order No. WQ 2013-0058-EXEC became effective that clarified and expanded requirements of the original MRP and defined new sanitary sewer overflow (SSO or spill) categories. The 2006 SSS WDRs and 2013 amendments were superseded by Order No. 2022-0103-DWQ, issued on December 6, 2022, and effective June 6, 2023. The SSO category definitions, as well as the notification, monitoring, and technical reporting requirements per the 2022 SSS WDRs are shown in Figure 1.

This monitoring plan addresses water quality monitoring requirements for Category 1 SSOs that are greater than or equal to 50,000 gallons. The WQMP was developed in November 2013, per requirements in Order No. WQ 2013- 0058-EXEC, and revised in April 2023 to meet requirements in the 2022 SSS WDRs.

SSO Monitoring Plan 3 April 2026

B DATA GENERATION AND ACQUISITION
B.1 SAMPLING PROCESS DESIGN
B.1.1 Sampling Event Timing
The Monitoring Coordinator will determine when the field crew will be mobilized to sample the receiving water.

Sampling is required for all spills where 50,000 gallons or more reach surface waters. Sampling must be conducted within 18 hours of City staff becoming aware of such a spill. The monitoring coordinator will target daylight sampling, but sample timing may be shifted due to safety and logistical issues.

Sampling will not be conducted if there are any concerns regarding field crew safety. These concerns may include heavy rain events, which compromise access points through flooding and swift currents. Thunderstorms will also be avoided when lightning is occurring. Sampling will only be conducted if there are at least two members of the field crew team available.

B.1.2 Monitoring Site Locations
Upon notice of a Category 1 SSO, the Monitoring Coordinator will determine where the field crew will sample. The Monitoring Coordinator will be responsible for determining the sampling locations. At a minimum, sampling will occur at the point where the SSO enters the water body, a point upstream of the entry point, and at least one point downstream of the entry point where the spill is expected to be fully mixed with the receiving water. The Monitoring Coordinator will provide a detailed description of potential monitoring site locations to the Field Crew.

If monitoring in the receiving water is not safe or feasible, samples may be collected at a point in the storm drain system.

Upon arrival at the monitoring sites, the Field Crew will determine the best locations to sample by assessing the hydrology of the receiving water and any safety precautions. The Field Crew should look for locations where the receiving water can easily be entered or sampled mid-channel by a grab pole. Once the sampling site location is selected, but before sampling starts, the Field Crew will record the latitude and longitude of the sampling location into the Field Form (APPENDIX A).

B.2 EQUIPMENT PREPARATION
The Field Crew shall maintain a sampling kit with the necessary supplies to conduct a monitoring event. Table 2 lists the equipment and supplies that will be included in the sampling kit.

B.2.2 Field Meter Calibration
All field meters will be properly calibrated and maintained by the Field Crew. Calibrations will be performed according to the methods and frequency recommended by the equipment manufacturer. When calibrating the instruments, the Field Crew will document all pertinent information in a Calibration Log (APPENDIX B) and keep it with the rest of the project documentation.

B.3 WATER QUALITY MONITORING
The Field Crew will be responsible for the following tasks upon arrival at the monitoring location:

1. Determine best sampling locations and record latitude and longitude readings for the upstream, SSO entry point, and downstream sampling sites. If monitoring in the receiving water is deemed unsafe or infeasible, samples may be collected at a point in the storm drain system.

Item #6.6.

Page 101 of 117 ends

City of Calistoga
SSO Monitoring Plan 5 April 2026

2. Collect water quality samples in the following order: first at the SSO entry point, second at the downstream site(s), and third at the upstream monitoring site.

3. Complete all field forms and prepare the samples for delivery to the laboratory.

The following sections outline the necessary steps the Field Crew must take when performing the above actions.

B.3.1 Sample Collection Methods
Sample collection methods will vary depending on the surface water and the safety of the Field Crew. Clean, powder-free, nitrile gloves will be worn for all bottle handling. The direct fill sample collection method is the preferred sampling method, since it does not use an intermediate container. In cases where the direct fill method cannot be used due to accessibility or safety an intermediate bottle and a grab pole can be used.

B.3.1.1 Direct Fill Sample Collection
The direct fill sample collection method will be used in cases where the surface water can be entered safely by the Field Crew. Field Crew will wear waders and ensure that the water level and velocity of the surface water are low enough to provide a safe entry and sampling environment.

Ammonia and bacteriological sample bottles will be filled by direct submersion to approximately mid-depth as follows.

1. Wade to approximately the area of the water body with the highest flow rate and face upstream. This will most likely be midstream, but can be in a different portion of the stream, depending on the hydrology.

2. Submerge the sample bottle with its cap on to approximately mid-depth at a location of significant flow (avoid stagnant water). Hold the bottle upright under the surface while it is still capped.

3. Open the lid carefully just a little to let water run in. Fill the bottle and screw the cap tightly while the bottle is still underneath the surface.

4. Remove bottle from stream and place on ice.

B.3.1.2 Intermediate Container Sample Collection
If the flow, water level and/or access point are deemed unsafe then an intermediate bottle attached to a grab pole will be used for sample collection. A clean, new intermediate bottle will be used for each sampling event and sampling site.

Ammonia and bacteriological sample bottles will be filled by intermediate container sample collection as follows:

1. Attach the intermediate bottle to an expandable pole using tape or cable ties and remove lid.

2. Submerge the intermediate bottle, attached to expandable pole, to approximately mid-depth at a location of significant flow (avoid stagnant water).

3. Remove bottle from water and empty contents. Repeat this twice more.

4. Once the intermediate bottle is properly rinsed, return it to approximately mid-depth at a location of significant flow (avoid stagnant water).

5. Using the intermediate bottle, fill the bacteriological sample container and then the ammonia bottle. Ensure that neither bottle overflows and that the preservative stays in the sample container.

STAFF REPORT
To: Honorable Mayor and City Council
From: Sheli Wright, Fairgrounds Revitalization Director Meeting: City Council Regular Meeting - Apr 21 2026
Subject: Fairgrounds Advisory Committee Capital Campaign Partnership with Native Son's Parlor 86 and Calistoga Fairgrounds Foundation
DESCRIPTION:

Committee Partnership with Native Son's of the Golden West, Parlor 86, and Calistoga Fairgrounds Foundation
RECOMMENDATION:

Consider Adopting the Resolution
SUMMARY:

On March 26, 2026, the Fairgrounds Advisory Committee's (FAC) Capital Campaign Subcommittee brought a motion to the FAC to work with the Native Sons of the Golden West, Parlor 86, and Calistoga Fairgrounds Foundation on a capital campaign to raise money for the heating and airconditioning for the Butler Building.

ANALYSIS:

The Fairgrounds Advisory Committee serves a critical role in identifying priorities, advising on improvements, and supporting the long-term sustainability of the Fairgrounds. As City resources remain limited, strategic partnerships with established nonprofit organizations present an opportunity to expand the City’s capacity to advance capital improvements while strengthening community engagement.

Collaboration with organizations such as the Native Sons of the Golden West and the Calistoga Fairgrounds Foundation provides a framework for leveraging community support, fundraising expertise, and volunteer networks. These partnerships can enhance the visibility of Fairgrounds needs while fostering broader public investment in the facility’s future.

The development of a structured capital campaign, guided by the Fairgrounds Advisory Committee and its subcommittee, would provide several key benefits:
 Identification and prioritization of capital improvement projects  Development of targeted and strategic fundraising initiatives  Strengthening partnerships between the City and community-based organizations  Increased public awareness, engagement, and financial support for the Fairgrounds As an initial step, the FAC, in partnership with the Native Sons and the Calistoga Fairgrounds Foundation, proposes a fundraising dinner, in the Tubbs building, as a pilot to evaluate the effectiveness of a collaborative capital campaign model. This event will allow the FAC, city staff, and its partners to assess fundraising capacity, community interest, and organizational coordination, while working toward an initial fundraising goal of $120,000 to support priority improvements.

Item #8.1.

Page 112 of 117 ends

Outcomes from this effort will help inform future campaigns and potential larger-scale capital improvement initiatives.

Importantly, this partnership is intended to serve as a foundation for broader collaboration and does not preclude participation by other nonprofit organizations, service groups, or community stakeholders. Expanding inclusion over time will be essential to building a sustainable and diversified funding strategy.

The proposed initial capital project, the installation of heating and air conditioning in the Butler Building, represents a practical and impactful investment. The Butler Building is a central Fairgrounds facility with significant potential for expanded use, including public meetings, community events, and emergency response operations. Enhancing the building with climate control will improve functionality, increase year-round usability, and position the facility as a more reliable asset for both routine and emergency purposes.

Overall, this pilot effort represents a strategic and measured approach to launching a capital campaign program, strengthening community partnerships, and addressing priority infrastructure needs at the Fairgrounds.

FINANCIAL IMPACT:

The fundraising event is anticipated to take place in the Tubbs Building, which rents for $2,500. The Native Sons have submitted a fee waiver request. Event proceeds are intended to support the Butler Building HVAC project, with an estimated project goal of approximately $120,000. If the waiver is approved, the City’s financial impact would be limited to the waived rental revenue and limited staff time.

CEQA STATUS:

This action does not meet the definition of a “project” under the California Environmental Quality Act (CEQA).

City of Calistoga | COMMITTEE REPORT
DATE: March 26, 2026
COMMITTEE INFORMATION: Fairgrounds Advisory Committee – Capital Campaign & Outreach; Bill Squire
DESCRIPTION: Consideration and direction regarding a collaborative campaign effort between the Native Sons, the Calistoga Fairgrounds Foundation, and the City of Calistoga Fairgrounds Advisory Committee to support improvements and long-term sustainability of the Calistoga Fairgrounds.

RECOMMENDATION: The Fairgrounds Advisory Committee is asking for approval to work in partnership with the Native Sons and the Calistoga Fairgrounds Foundation to develop and implement a capital campaign program of support for the revitalization of the Butler Building. Initial efforts would include planning and hosting a fundraising dinner event to support priority capital improvements, specifically the installation of heating and air conditioning in the Butler Building.

SUMMARY: The Calistoga Fairground serves as a critical community asset, supporting heritage, community events, and emergency response functions. Continued investment is necessary to maintain and enhance facilities to meet current and future needs.

A collaborative capital campaign is proposed to leverage community partnerships and philanthropic support. The Native Sons and the Calistoga Fairgrounds Foundation have expressed interest in working together alongside the City’s Fairgrounds Advisory Committee to develop fundraising strategies and community engagement efforts.

As an initial project, the partners propose hosting a fundraising dinner event to generate support for the installation of a heating and air conditioning system in the Butler Building. This improvement will enhance year-round usability, increase rental opportunities, and improve comfort for community events. The fundraising goal for this effort is $120,000.

ANALYSIS: The Fairgrounds Advisory Committee plays an important role in guiding improvements and ensuring the long-term viability of the Fairgrounds. By partnering with established nonprofit community organizations such as the Native Sons and the Calistoga Fairgrounds Foundation, the City can expand its capacity to raise funds and engage the public.

A structured capital campaign will allow for: Identification and prioritization of capital improvement projects - Development of targeted fundraising strategies - Strengthening of community partnerships - Increased visibility and support for the Fairgrounds The proposed first partnership project is a fundraising dinner that will serve as a pilot effort to evaluate the effectiveness of collaborative fundraising initiatives. Success of Item #8.1.

Page 116 of 117 ends

this event may inform future campaigns and larger-scale capital efforts. Additionally, it should be noted that this partnership is meant as a beginning of relationships and does not exclude other nonprofits or organizations from getting involved in support efforts for the fairgrounds.

We believe that the Butler Building is a key facility within the Fairgrounds and that it should be used for meetings, events, and emergency operations. The addition of heating and air conditioning will significantly improve functionality and expand seasonal use, making it a strong candidate for initial community fundraising efforts.

FINANCIAL IMPACT: There is no immediate fiscal impact on the City’s General Fund associated with providing direction and authorization for the Butler building capital campaign. Costs associated with the capital improvements will be supported through fundraising efforts and potential external contributions.

The initial fundraising goal for the Butler Building HVAC project is $120,000.

CEQA STATUS: The proposed direction does not constitute a project under the California Environmental Quality Act (CEQA) and is therefore not subject to environmental review at this time. Any future capital improvements will be evaluated for CEQA compliance as required.
