A. This Section describes the anticipated control programming under this Contract.

B. Process Control Functions:
a. Process control function shall be structured to permit the realization of all control strategy requirements. In addition, each control function shall be designed so that bumpless, balance free transfers are obtained during operating mode changeover and initialization. Where applicable, user-changeable parameters shall be automatically defaulted to a preset value if a specific value is not given during system generation. b. The P&IDs represent the required process monitoring and control. The required control for the system is a combination of the representation on the P&IDs and the requirements specified herein. The P&IDs do not show all the required internal diagnostic indications. In addition to the indications shown on the P&IDs, at a minimum, the following shall be provided:
c. Indication of bad quality on any hard-wired input/output point (such as zero milliamps on a 4 to 20 mADC circuit).
d. Individual PLC fault indications.
e. Indication of a communications failure with an alarm generated at the operator display.
f. For all motor start and stop commands check for run feedback after adjustable time delay (0 to 120 seconds). Provide a “FAIL TO START” and “FAIL TO STOP” alarm if unit fails to start or stop. Use the failure start or stop bit to remove the run command from the control logic. The alarm should not be generated within the hardwired pump restart timer. These alarms should not apply while the BYPASS MODE is active. g. For all VFD motors, provide a speed discrepancy alarm when the speed command setpoint is outside of an adjustable Deadband position setpoint (0 to 50 percent) from the speed feedback after an adjustable time delay (0 – 120 seconds). Use the failure bit to remove the run command from the control logic.
h. For all motors, provide an adjustable restart delay setpoint (0 to 120 seconds) to prevent the motor from being started from the HMI after being stopped. The motor should not be restarted until the delay time has elapsed to allow for motor winddown.
i. For analog control loops, when control of field equipment is not in “REMOTE,” the associated PID controller output shall track the position feedback.
j. Runtimes and start counts shall be provided for all pieces of equipment, including today, yesterday, this week, last week, this month, last month, and lifetime totals.
k. Flow totals shall be provided for all flow meters, including today, yesterday, this week, last week, this month, last month, and lifetime totals. Provide a total for each month of the previous 12 months.
l. All Alarms and Switches shall be time delayed. Delay settings shall be adjustable from the HMI.
m. All Alarms shall be enabled/disabled at the PLC level based on the operating status of systems and devices, such that nuisance alarms associated with offline equipment are prevented.
n. All alarms shall be capable of being enabled/disabled from the respective screen on the HMI. When disabled, the instrument or device shall have a

graphic symbol at the HMI indicating its alarms have been disabled. The system shall have a screen that indicates which alarms are disabled. o. Shutdown alarms are to be manually reset for the operator to verify that the equipment can be restarted safely. A single acknowledgement will reset the alarms.
p. For Shutdown alarms, (HW) denotes that it is a hardwired interlock. (SW) denotes a software interlock.
q. All analog alarms shall be configured in the PLC with debounce and other applicable features. All alarms must comply with ISA 18.2. For all analog signals, provide the following alarm indications:
a) “High-high.”
b) “High.”
c) “Low.”
d) “Low-low.”
e) “Instrument Failure.” (i.e. outside of the 4 to 20 mADC range or AI module failure)
r. In addition to the indications shown on the P&IDs, the following shall be provided at a minimum:
s. Analog Data Scaling: This control function shall scale all analog inputs to a common span and shall normalize the digital representation of each analog input to a percent of the operating span. The processed value shall be expressed as a binary number that specifies the analog input's position on a straight line lying between zero and full scale.
t. Engineering Unit Conversion: This control function shall convert scaled analog data to engineering units by means of the following equation:

Y = (H - L) (D/DH) + L
where:

Y = Value in engineering units.

H = High value of span, expressed in engineering units.

L = Low value of span, expressed in engineering units.

D = Digitized scaled input value in counts.

DH = Full scale digitized value in counts.
u. Manual Control: It shall be possible for operator to interrupt any sequence, loop or automatic operation and operate the same equipment manually through the operator display.
v. Verification of Digital Outputs: This control function shall verify that the equipment has responded to the digital commands before proceeding to next step during automatic operation. If any discrepancy is detected, an alarm will be annunciated, and function stopped.

C. Hardware: CONTRACTOR shall provide all the hardware and software, as shown, specified or required to implement the control strategies as described.

D. Configuration: All set points, tuning parameters and engineering scales etc. shall be documented for each control point and each control strategy on configuration sheets or similar documents. These documents shall be updated during Factory Testing and finally during start-up to be included with updated Process Control Descriptions.

E. Control Displays: Control displays shall be submitted for review. Displays shall clearly show information in a logical format including historical totals, alarms, and trending.

6. Draft Resolution- Planning and Building Services Fee Schedule Summary: Council will consider and possibly adopt a resolution amending the Fee Schedule for the Planning and Building Divisions of the Community Development Department to eliminate fee discounts for select uses and establish an Administrative Use Permit fee.

Background: The Community Development Department currently consists of the Divisions of Planning, Building, Housing, Code Enforcement, Fire Prevention, Grants Management, Business Services, and Climate Adaptation and Resilience. Below is a chronology of past Council directives and actions related to amendments to the Planning and Building Services Divisions, the two Cost Recovery divisions of the Department, within the last two years, along with additional detail provided through Attachments. Staff action related to the below history has been undertaken in coordination with the Fee Schedule Review Ad Hoc Committee and Zoning Reform Ad Hoc Committee, both of which consist of Mayor Crane and Councilmember Orozco as appointed Councilmembers.

February 2024 Fee Schedule Amendments and Council-Directed Tasks On February 21, 2024, Council adopted Resolution No. 2024-05 (Attachment 1), amending the Fee Schedule of the Planning and Building Divisions of the Community Development Department. In addition to amendments made to the Fee Schedule, Council also directed Staff to revise the layout of the online fee schedule posted on the webpage of the Planning Division and available at the front counter such that terms are well-explained and the information is easier to access/understand. Additionally, Council directed Staff to conduct further research and analysis into the existing fee reduction categories (Attachment 2 and contained within the table of Resolution No. 2024-05, under #13) and present a report to Council with recommendations on those fee reductions.

May 2024: Completion of Tasks 1 and 2 and Additional Council Direction Shortly after Council adoption of Resolution No. 2024-05, Staff posted a revised layout of the online fee schedule on the webpage of the Planning Division (https://cityofukiah.com/community-development/planningservices/), as well as making it available at the front counter. To ensure terms were well-explained and the

information easier to access/understand, Staff also developed a new supplement to the Planning Division's fee schedule, which is also accessible online and at the front counter of the Community Development Department (titled Supplement to City of Ukiah Fee Schedule).

With Task 1 completed, on May 15, 2024, Staff presented a report and recommendations regarding research into the existing fee discount categories of select services of the Planning Division of the Community Development Department. The report concluded the following:

1. Based on the research and analysis in this report, Staff finds no evidence that the fee discounts incentivized development of the types of projects originally envisioned. Developers have commented throughout the last seven years that they are primarily seeking certainty in the entitlement process, rather than reduced fees.

2. Planning approaches such as "performance zoning," where a city or county adopts an administrative approval process for certain uses that meet objective performance standards, may prove more effective in incentivizing the types of projects first envisioned within the 2016 fee schedule.

3. Current State laws, such as the California Building Code, mandate such energy conservation and solar measures listed on the 2016 fee schedule. Where not mandated by State law, the City has integrated many of the Project Design and Energy and Water Conservation features into the Objective Design and Development Standards for new housing projects. The same types of standards could be designed for commercial projects.

Staff also proposed two recommendations, which Council directed, consisting of the following:

1. Direct Staff and the Zoning Reform Ad Hoc to explore the development of a new Administrative Use Permit (AUP) and/or make additional recommendations on how to streamline entitlement processes. After preliminary discussions with the Zoning Reform Ad Hoc, at the minimum AUPs may be appropriate for former "level 1" minor permit types, as well as public art, community gardens, outdoor dining, live entertainment, sidewalk cafes, and tasting rooms.

2. Direct Staff to bring back an amendment to the existing fee schedule at a future Council meeting to remove fee discounts and/or make additional changes to fees for AUPs and other planning permits.

Agenda Summary Reports detailing the analysis pertaining to recommendations for the February 21, 2024, and May 15, 2024, meetings are included as Attachment 3.

Development and Adoption of AUP Ordinance: May 2024-August 2025 The Zoning Reform Ad Hoc met with and provided input to Staff approximately once every 2-3 months beginning in 2024. Upon Staff's creation of a draft outline of the Ordinance and after conferring with the Chair of the Mendocino County Airport Land Use Commission (ALUC), in accordance with Policy 1.4(b) of the Ukiah Municipal Airport Land Use Compatibility Plan (UKIALUCP), in October 2024 Staff referred the outline of the ordinance to the ALUC for a consistency determination. On December 9, 2024, the ALUC determined the proposed approach consistent, as well as directing City Staff's recommendation of an annual report to the ALUC each year, starting in January 2026, for future City ordinances. After finalizing the language of the Ordinance in early 2025, Staff presented the Ordinance to Planning Commission on July 9, 2025, which the Commission unanimously recommended to the City Council. On August 20, 2025, Council unanimously introduced the Ordinance, which is proposed for adoption on September 3, 2025.

Discussion: Of the Council-directed tasks and actions, the one remaining task is Council consideration of the elimination of the discounts for select fees of the Planning Services Division. Staff is also proposing a fee for the new Administrative Use Permit.

Fee Schedule Discount Recommendation
As mentioned above, Staff presented a full analysis of the fee discounts in May 2024. That report is included again as Attachment 4. The original purpose of the fee schedule discounts can be found in past staff reports written by the previous Planning and Community Development Director, Charley Stump. Proposed fee

reductions were suggested as "incentives" to encourage "...projects that provide significant economic development, new industrial/manufacturing development, significant energy conservation, and certain public benefits." (Director Stump, 4/20/16 staff report and Page 2 of Attachment 4).

One of the conclusions reached by Staff after analyzing permit history since the fee discounts had been in place was that there was no evidence fee discounts incentivized development of the types of projects originally envisioned. Instead, project applicants have commented that they are primarily seeking certainty in the entitlement process, rather than reduced fees. Additionally, it appears that if fees are set at rates that are “excessive,” or above regional market rates for fees, they can act as barriers to development. (pages 3 and 4 of Attachment 4)
Through the Department's reorganized structure of multiple team members of the Department being crosstrained to provide a suite of different Community Development services, plus significantly increased grant revenue, the Department has been able to literally do more with a lessening impact to the General Fund.

Further increases in efficiency of service provision and economies of scale have in recent years accelerated this trend, the result of which, among other positives such as quicker processing times and more responsive customer service, is less reliance on revenue from fees. Because the City relies less on revenue from fees from planning and building permits, it can set competitive rates for these services relative to area jurisdictions.

As an example of this, see Attachment 5 for a comparison of select planning permit fees between the City of Ukiah and the County of Mendocino.

AUP Fee Recommendation
Based on time and cost spent on similar types of processes, such as the Director's Determination, Staff is recommending a flat fee for the Administrative Use Permit of $350. The fee would provide for application intake and processing, as well as initial analysis and recommendations from a planner and review and possible approval, with findings, from the Community Development Director. As this new permit type is deployed and utilized by the community, Staff will evaluate if this fee is appropriate and update the Council in the future if the fee should be adjusted.

Based on the analysis and research conducted within this staff report, as well as staff reports and research during the last two years and with input from the Fee Schedule and Zoning Reform Ad Hoc Committees, Staff recommends Council adopt the Resolution in Attachment 6 amending the Fee Schedule of the Planning and Building Services Divisions of the Community Development Department.

Recommended Action: Adopt Resolution amending the Fee Schedule for the Planning and Building Divisions of the Community Development Department.

1 Planning Division Fee Schedule Discounts
Historical Research and Analysis Report
May 2024
Overview
Research was conducted by City Staff into the origin of Community Development Department Planning Division fee discounts in place as of the date of the last adoption of the Fee Schedule in February 2024 (Resolution No. 2024-05). The report below provides details of this research, as well as conclusions.

Summary of Research into Historical Documents

1. Fees for planning and zoning activities were modified a total of six times between 1964 and 2002, but per an April 20, 2005, staff report prepared by former Planning and Community Development Director Charley Stump, 2002 appears to be the first year in which both cost recovery and fee discounts were implemented. "The purpose of raising the fees in 2002 was to maintain an approximate 75% salary cost recovery for processing the planning and zoning permit applications. Director Stump further noted “The City Council at that time felt comfortable providing a 25% subsidy to the development community to "assist" economic development."
Director Stump's assertion that the 2002 City Council sought to utilize a 25% subsidy to assist (incentivize) economic development is validated by a review of Resolution No. 2002- 41, adopted June 19, 2002. In addition to the subsidy for economic development, through Recital #10 the Resolution also established the first instance of discounted fees- in this case for affordable and special needs housing projects.

Recital 10- The City desires to provide an incentive to affordable housing projects by not increasing the current fees for projects involving 100% of the housing units to be "locked-in" affordable to citizens earning less than 80% of the area median income, "sweat-equity" residential projects, residential second units, and projects involving housing for identified groups in need such as seniors, homeless persons, and the mentally ill.

2. The practice of fully recovering the costs of certain major planning permits, known as Cost Recovery, was first implemented by the City on June 1, 2005, through the Council’s adoption of Resolution No. 2005-47. Prior to that date, all applications were processed as "Level 1" or "Level 2" permits subject to a "flat rate" fee approach.

A Cost Recovery Study undertaken to make recommendations to the Council for the 2005 fee schedule update indicated that the fees collected for the processing of planning permits ATTACHMENT 4

2 ranged from 4.7% to 17% of the cost of processing the permits. In other words, the Cost Recovery Study found that prior to adoption of the Cost Recovery practice, the City was subsidizing 83% – 95.3% of the total cost for major planning permit development projects.

Because adoption of Resolution No. 2005-47 resulted in major planning permits being subject to full cost recovery, the 25% subsidy for economic development was in effect discontinued. However, the Resolution did prescribe a new 20% discount for affordable housing projects and a 40% discount for special needs housing projects, as depicted in Recitals #14 and #15:

Recital 14- The City desires to maintain low fees (80% cost recovery) for affordable housing projects (projects that are "locked-in" affordable to citizens earning less than 80% of the area median income, "sweat-equity" residential projects, and residential second units).

Recital 15- The City desires to maintain low fees (60% cost recovery) for projects involving housing for identified groups in need such as seniors, homeless persons, and the mentally ill.

3. No additional fee discounts were adopted in 2007 through Resolution No. 2007-11, which was the last adopted fee schedule for the planning division until 2016. The 2007 Resolution continued the aforementioned affordable housing and special needs fee discounts.

4. The origin of the remaining six fee discounts dates back to an April 20, 2016, staff report prepared for the Council by Director Stump. The staff report proposed fee reductions as "incentives" to encourage "...projects that provide significant economic development, new industrial/manufacturing development, significant energy conservation, and certain public benefits." (Director Stump, 4/20/16 staff report)
This is also when the fee discount table was first introduced by Staff. In the April 20, 2016, staff report, the table is described as "Preliminary Fee Reductions to Promote Economic Development, Energy Conservation and Public Benefits" and the description is that "Staff has developed a number of potential fee reductions to promote local economic development and energy conservation and to incentivize projects that provide public benefits." On June 1, 2016, Council adopted Resolution No. 2016-30, approving Staff’s recommendations for fee discounts. The fee discount table within the resolution is shown in Figure 1 below. The description of the purpose of the fee discounts is described within Recital 13 of Resolution No. 2016-30:

Recital 13: The City has determined that fee reductions for projects that promote/provide economic development, energy conservation and public benefits is reasonable and appropriate.

5. Fee discounts first adopted in June 2016 have been continued within all subsequently adopted fee schedules, for the years 2017, 2018, 2020, and 2024.

Analysis
There are different approaches to incentivizing certain types of development. Some jurisdictions opt for reducing fees. Others seek to add certainty into the zoning and permitting process, including streamlining of permits and processes. Although the first approach of reducing fees can be easier for Planning and Community Development Departments to implement, involving little if any changes to zoning or processes, Staff was unable to find clear data or studies demonstrating that a fee reduction alone incentivized development.

Rather, it appears that if fees are set at rates that are “excessive,” or above regional market rates for fees, they can act as barriers to development.

4 Related to housing development, for example, a book written by Shawn Phillips in 2020, The Affordable City- Strategies for Putting Housing Within Reach (and Keeping it There), recommends cities implement such strategies as "Strive for Objective, Consistent Rules," (Chapter 12), "Increase Zoning Capacity" (Chapter 15), "Upzone Many Places at Once" (Chapter 16), "Allow Housing in Commercial Zones" (Chapter 19), "Make Development Approvals By Right" (Chapter 24), and "Speed up the Entitlement Process" (Chapter 25).

Indeed, the City has enacted many of these recommended strategies through accelerated implementation of the 2017 Housing Strategy and 2019-2027 Housing Element, facilitating the greatest number of new housing units constructed over a five-year period than at any point in the City's history, as well as the City's earning of HCD's coveted ProHousing designation.

Comparisons of Planning Division Application Data Since June 1, 2016 To analyze the impact the eight fee discounts had on incentivizing economic development, energy conservation, and public benefit-producing projects, Staff reviewed the number of new planning applications received, by year, since the adoption of Resolution No. 2016-30 for each of the eight categories. This data was then compared to the total number of all applications received for each year to understand if any causal relationship may be present. • 6/1/16-12/31/16: one (1) application received for fee discount category out of total of 18 applications.
• Calendar Year (CY) 2017: four (4) applications received for fee discount categories out of total of 29 applications.
• CY 2018: one (1) application received for fee discount category out of total of 38. • CY 2019: one (1) application received for fee discount category out of total of 27. • CY 2020: zero (0) applications received for fee discount categories out of total of 19. • CY 2021: four (4) applications received for fee discount categories out of total of 30. • CY 2022: three (3) applications received for fee discount categories out of total of 24. • CY 2023: one (1) application received for fee discount category out of total of 11. • 1/1/24-4/30/24: one (1) application received for fee discount category out of total of 9.

Additional Statistics of Note
• For all years, 2016-2024, zero (0) applications were received for the categories of Project Design or Industrial/Light Manufacturing.
• Two (2) applications were submitted within the Energy and Water Conservation Design category, and both of these were for housing projects submitted in 2017. • Of the seven (7) applications for businesses within the Downtown during the period, only one was for a new construction project.
• By a nearly two-to-one margin, the most frequently submitted application type for 2016-2024 was the minor use permit, which is not subject to cost recovery or fee discounts.

Conclusions

1. Based on the research and analysis in this report, Staff finds no evidence that the fee discounts incentivized development of the types of projects originally envisioned.

Developers have commented throughout the last seven years that they are primarily seeking certainty in the entitlement process, rather than reduced fees.

5 2. Planning approaches such as "performance zoning," where a city or county adopts an administrative approval process for certain uses that meet objective performance standards, may prove more effective in incentivizing the types of projects first envisioned within the 2016 fee schedule.

Although not yet studied in-depth by Staff, performance zoning and other types of “dynamic zoning” could incentivize economic development efforts, particularly within the downtown.

Performance zoning may still result in cost savings to applicants (in no longer needing discretionary review) while potentially enabling speedier implementation of many of the City's General Plan goals, particularly in the areas of land use, housing, economic development, and local agriculture. This approach could also provide an alternative to the time-intensive and often costly comprehensive zoning code update, as impactful General Plan land use implementation programs could be made incrementally.

The success of the zoning code amendment adopted by Council in 2021 to allow new housing construction by right in commercial and residential zoning districts, provided the project meets the City's Objective Design and Development Standards, is a good example of performance zoning. The first such by-right housing project in Ukiah, Acorn Valley Plaza, was through the City's objective design standards review process and issued a building permit within two months of submittal of the building permit application. With two other multiunit housing projects currently in the pipeline, this approach is proving effective for facilitating new housing.

3. Current State laws such as the California Building Code mandate such energy conservation and solar measures envisioned within the 2016 fee schedule. Where not mandated by State law, the City has integrated many of the Project Design and Energy and Water Conservation features into the Objective Design and Development Standards for new housing projects.

The same types of standards could be designed for commercial projects.

RESOLUTION NO. 2025-__

RESOLUTION OF THE CITY COUNCIL OF THE CITY OF UKIAH AMENDING THE FEE

SCHEDULE OF THE PLANNING AND BUILDING SERVICES DIVISIONS OF THE

DEPARTMENT OF COMMUNITY DEVELOPMENT TO ELIMINATE FEE DISCOUNTS FOR

SELECT USES AND ESTABLISH A NEW FEE FOR THE ADMINISTRATIVE USE PERMIT WHEREAS:

1. Community Development Department (“Department”) Planning and Building Permit service fees were last updated on May 21, 2025, through Resolution No. 2025-25; and

2. The City Council appointed a Community Development Department Fee Schedule Ad Hoc Committee comprised of Councilmembers Crane and Orozco to provide input and recommendations in the updating of the Department’s Fee Schedule; and

3. As directed by the City Council, the Department conducted a Historical Research and Analysis Report (“Report”) in May 2024 for the Planning Division Fee Schedule Discounts within the 2024 Fee Schedule; and

4. Among other conclusions, the Report found no evidence that the fee discounts incentivized development of the types of projects originally envisioned; and

5. Because of the conclusions reached within the Report, the City has determined that a fee reduction for projects that promote/provide economic development, affordable and special needs housing, energy conservation and public benefits is no longer reasonable or appropriate; and

6. On August 20, 2025, the City Council unanimously introduced an ordinance establishing an Administrative Use Permit for certain uses; and

7. Due to the estimated costs for the processing and approval or denial of administrative use permits, it is reasonable and appropriate to set a flat fee for this permit at $350; and

8. A public notice was posted in the Ukiah Daily Journal on August 23, 2025 to notify the public of the possible changes to the Fee Schedule and give the public an opportunity to make their comments known; and

9. The City Council conducted a duly noticed public hearing on September 3, 2025, to discuss and receive public comments on proposed changes to the Fee Schedule.

NOW, THEREFORE, BE IT RESOLVED that the City Council hereby adopts the updated fee schedule for planning and building permits and services of the Community Development Department, as listed on the attached Exhibit A.

Summary: The City Council will review and consider approving the 2025 Sewer System Management Plan.

Background: The State Water Resources Control Board (SWRCB) first issued its Statewide Waste Discharge Requirements (WDR) Sanitary Sewer Systems (Order No. 2006-0003) in May 2006. The order required public agencies that own or operate a sanitary sewer system to develop and implement an Sewer System Management Plan (SSMP) aimed at reducing sewer spills or Sanitary Sewer Overflows (SSOs). It also required agencies to report all SSOs electronically to the SWRCB.

The City of Ukiah (City) and Ukiah Valley Sanitation District (UVSD or District), which are both enrolled under the WDR, first developed a SSMP in July 2009. The initial SSMP was prepared by Winzler & Kelly to meet the requirements of the 2006 Order. The SSMP preparation effort compliments the maintenance, management and policy activities that the City and District are undertaking and provides a framework for organizing, measuring and monitoring on-going activities. The SSMP has been updated as needed over the years, most recently by Larry Walker Associates (LWA) in August 2025 (Attachment 1) in order to meet the requirements stipulated in the Statewide General Waste Discharge Requirements for Sanitary Sewer Systems Order No.

WQ 2022-0103-DWQ (2022 SSS WDR), which supersedes the 2006 order and its subsequent amendments.

The SSMP describes how the City and District construct, manage, operate, and maintain their sanitary sewer system by addressing each of the 11 elements of the plan. These elements are summarized below:
(1) Introduction and Goals
(2) Organization and Chain of Communications for SSMP
(3) Legal Authority to Operate and Maintain Sewage Collection System (4) Sewer System Operation & Maintenance Program
(5) Sewer System Design and Performance Provisions
(6) Spill Emergency Response Plan
(7) Sewer Pipe Blockage Control Program
(8) System Evaluation and Capacity Assurance and Capital Improvements (9) Operation and Maintenance Monitoring, Management and Plan Modifications (10) SSMP Audits
(11) Communication Program with Public and Stakeholders Discussion: Staff recommends approval of the 2025 Sewer System Management Plan (Attachment #1). UVSD will consider approval at its September 10th meeting.

Recommended Action: Approve Sewer System Management Plan 2025 Update.

SANITARY SEWER MANAGEMENT PLAN
1 INTRODUCTION AND GOALS

1.1 REGULATORY REQUIREMENTS FOR THE INTRODUCTION AND GOALS

ELEMENT
The regulatory requirements for the Introduction and Goals Element of the Sewer System Management Plan (SSMP) are summarized as follows:
a) The SSMP narrative introduction must discuss the following: (1) Regulatory Context, (2) SSMP Update Schedule, and (3) Overview of the Sewer System Assets, with a reference to a Sewer System Map that can be made available to the state Water Resources Control Board (SWRCB).
b) The goal of the SSMP is to provide a plan and schedule to: (1) properly manage, operate and maintain all parts of the sanitary sewer system, (2) reduce and prevent Sanitary Sewer Overflows (SSOs) or spills, and (3) contain and mitigate any spills that do occur.

1.2 REGULATORY BACKGROUND
The SWRCB first issued its Statewide Waste Discharge Requirements (WDR) Sanitary Sewer Systems (Order No. 2006-0003) in May 2006. The order required public agencies that own or operate a sanitary sewer system to develop and implement an SSMP aimed at reducing sewer spills or SSOs. It also required agencies to report all SSOs electronically to the SWRCB.

The City of Ukiah (City) and Ukiah Valley Sanitation District (UVSD or District), which are both enrolled under the WDR, first developed an SSMP in July 2009. Ukiah is a full service City governed by an elected Council. The District is a special purpose district governed by an elected Board. The initial SSMP was prepared by Winzler & Kelly to meet the requirements of the 2006 Order. The SSMP preparation effort compliments the maintenance, management and policy activities that the City and District are undertaking and provides a framework for organizing, measuring and monitoring on-going activities. The SSMP has been updated as needed over the years, most recently by Larry Walker Associates (LWA) in August 2025 in order to meet the requirements stipulated in the Statewide General Waste Discharge Requirements for Sanitary Sewer Systems Order No. WQ 2022-0103-DWQ (2022 SSS WDR), which supersedes the 2006 order and its subsequent amendments.

The SSMP describes how the City and District construct, manage, operate, and maintain their sanitary sewer system by addressing each of the 11 elements of the plan. These elements are summarized below:
(1) Introduction and Goals
(2) Organization and Chain of Communications for SSMP
(3) Legal Authority to Operate and Maintain Sewage Collection System (4) Sewer System Operation & Maintenance Program
(5) Sewer System Design and Performance Provisions
(6) Spill Emergency Response Plan
(7) Sewer Pipe Blockage Control Program
(8) System Evaluation and Capacity Assurance and Capital Improvements

(9) Operation and Maintenance Monitoring, Management and Plan Modifications (10) SSMP Audits
(11) Communication Program with Public and Stakeholders

1.3 SEWER SYSTEM MANAGEMENT PLAN UPDATE SCHEDULE
Based on new requirements in the 2022 SSS WDR, SSMPs are to be updated and re-certified by governing bodies (City Council or Board of Directors) on a six-year frequency, with the first update being due August 2, 2025, for a service area between 10,000 and 100,000, such as the City of Ukiah. The District serves a smaller population, and its regulatory due dates are offset by nine months from the City’s deadlines (i.e., the District’s SSMP update deadline is May 2, 2026).

Because this document covers both agencies, it is being prepared to accommodate the stricter requirements.

In addition to SSMP updates, the SSS WDR requires that SSMP internal audits be conducted at a three-year frequency. Internal audits are conducted to document the success of the SSMP and evaluate how to improve current procedures to ensure the goals and objectives of the SSMP continue to be met. Results and recommendations from SSMP audits guide revisions to the SSMP as deficiencies and improvements are identified. The most recent SSMP Audit was conducted in April 2025.

The City and District’s SSMP internal audit, updates, and re-certification schedule from 2025 through 2031 is presented in Table 1.

1.4 SEWER SYSTEM ASSET OVERVIEW
The City of Ukiah is located in the Ukiah Valley in southern Mendocino County. It was incorporated in 1876 and has an estimated current population of 16,000 people. The City owns and operates the City of Ukiah Wastewater Treatment Plant (WWTP) and associated sewer system (collectively referred to as the Facility). The facility serves the City and residential areas to the north and south of Ukiah, as well as east of the Russian River, in Mendocino County.

The Facility treats wastewater from two entities, the City and UVSD, which total an approximate population of 22,000. UVSD also serves Mendocino College, El Dorado Estates, Vichy Springs and areas contiguous to the City. UVSD owns the collection system in its service area and the City maintains it. The District’s facilities are generally satellite facilities to the City’s collection system.

CITY OF UKIAN AND UKIAH VALLEY SANITATION DISTRICT August 2025 | 3

SANITARY SEWER MANAGEMENT PLAN
The City does not accept wastewater from any collection system not owned or maintained by the City. A map of the City and UVSD systems is shown in Figure 1.

The sewer system in the City and UVSD consists of approximately 67 miles of pipelines that are 6-inches in diameter or larger. A trunk sewer that ranges in size from 15 to 42 inches in diameter extends northward from the facility for a distance of 6 miles. The majority of the sewers are gravity collection lines. There are no bypasses or overflow structures in the system. Three lift stations from El Dorado Estates, Ford Street, and Vichy Springs discharge to force mains that cross under the Russian River. Each lift station has a bypass pipe around the pumps that allows the system to flow by gravity (via a siphoning effect) and prevent lift station overflows. Upper and lower laterals are privately owned and the sole responsibility of the owner. The City can, however, provide assistance during emergencies.

The City and the District are considering updating the Wastewater Ordinance to split the responsibility for the laterals at the public right of way (whereas the City/District would be responsible for the lower laterals); however, at the time of this SSMP update, there is no projected timeline for this potential policy change.

With respect to stormwater infrastructure, the City manages its stormwater infrastructure; therefore, access to maps and facilities during spills are readily available to responding staff.

There are no structures diverting stormwater to the sewer system in the City jurisdiction. UVSD does not have an underground stormwater collection system; any spills in the UVSD jurisdiction can be visually tracked to nearby ditches. In case of an emergency within the UVSD boundary, City staff can obtain access to maps and facilities from UVSD staff.

The flow from commercial and business facilities is approximately 28 percent of the total WWTP inflow. Commercial and business facilities served by the facility include restaurants, hotels, car washes, automotive mechanics, car dealerships, hospitals, dental offices, photo processors, and other typical small city businesses. The remaining 72 percent of flow is considered residential flow. The City does not accept flow from septage, chemical toilets, or other bulk waste sources.

As of 2025, the City has 2,985 residential connections and 566 commercial connections and UVSD has 1,002 residential connections and 136 commercial connections.

1.5 SEWER SYSTEM MANAGEMENT PLAN GOALS
Both the City Council and the Ukiah Valley Sanitation District Board of Directors have approved the following goals for the SSMP program:
(1) Maintain or improve the condition of the collection system infrastructure in order to provide reliable service now and into the future.
(2) Cost-effectively minimize infiltration/inflow (I&I) and provide adequate sewer capacity to accommodate design storm flows.
(3) Minimize the number and impact of SSOs that occur.
2 ORGANIZATION
This section of the SSMP identifies City staff responsible for implementing the SSMP, responding to spill events, and meeting the spill reporting requirements. This section also includes the designation of the Authorized Representative to meet SSS WDR requirements for completing and certifying spill reports.

2.1 REGULATORY REQUIREMENTS FOR ORGANIZATION ELEMENT
This element must identify:
a) The name of the Legally Responsible Official;
b) The position titles, telephone numbers, and email addresses for management, administrative, and maintenance positions responsible for implementing specific SSMP elements;
c) Organizational lines of authority; and
d) Chain of communication for reporting spills from receipt of complaint or other information, including the person responsible for reporting spills to the State and Regional Water Boards and other agencies, as applicable.

2.2 ORGANIZATION DISCUSSION
The City’s policy making body is the City Council, which consists of five elected members. The City Council is a general governmental body and among its many activities, the Council sets policy, approves rates, and authorizes contracts related to its sewer collection system and wastewater treatment plant.

The Ukiah Valley Sanitation District’s policy making body is its Board of Directors, which consists of five elected members. The District’s Board of Directors is a special purpose board, focusing only on sewer system issues. The Board of Directors sets policy, approves rates and authorizes contracts related to its sewer collection system and trunk lines.

The City and the District have a contractual relationship that affects both the treatment plant and sewer collection system. The District has a capacity share in the treatment plant, which the City owns and operates. The District has also contracted with the City to operate the collection system that it owns. All engineering and operational staff persons are employees of the City.

CITY OF UKIAN AND UKIAH VALLEY SANITATION DISTRICT August 2025 | 6

SANITARY SEWER MANAGEMENT PLAN
The City’s chief executive is the City Manager, who enforces policy, plans strategy, leads staff, allocates resources, delegates responsibility, authorizes outside contractors to perform services, and generally leads communication to the public. The District is managed by a District Manager, who is the District’s sole paid employee. The District Manager enforces policy, plans strategy and serves as the liaison to the City on contractual matters.

The City staff includes a City Clerk and the District Manager provides clerk services for the District. The clerks’ functions include publication of agendas, minutes and notices in accordance with the law, management and filing of Ordinances and Resolutions adopted by the Council and Board of Directors and arrangement for emergency meetings if necessary.

The Department of Public Works organization chart for day-to-day operations is illustrated in Figure 2. This staff provides for the engineering and operational needs of both City and District facilities. The roles and responsibilities of day-to-day operational staff are described below.

Director of Water Resources (Director) – Prepares wastewater collection system planning documents, manages capital improvement delivery system, documents new and rehabilitated assets, and coordinates development and implementation of SSMP. The Director provides management oversight for the Water and Collection Systems Distribution as well as for the Water and Wastewater Treatment groups. The Director reports to the City Manager and serves as a liaison with the District.

Water/Sewer Maintenance Supervisor – The Maintenance Supervisor ensures that new and rehabilitated assets meet agency standards, works with field crews to handle emergencies when contractors are involved, provides verbal reports to the Director and implements enforcement actions.

Collection System Operation and Maintenance Group – The Collection System Operations and Maintenance Group includes the Water/Sewer Maintenance Supervisor and the Field Crew. The Water/Sewer Maintenance Supervisor manages field operations and maintenance activities, provides relevant information to agency management, prepares and implements contingency plans, leads emergency response, investigates and reports SSOs, and trains field crews. The Field Crew includes staff that conducts preventive and corrective maintenance activities, and mobilizes and responds to notification of stoppages and SSOs (i.e., mobilize sewer cleaning equipment, bypass pumping equipment, and portable generators).

This element of the SSMP provides a summary of the City’s and District’s legal authority to operate, maintain, and enforce standards for the wastewater collection system. The City’s and District’s respective authority includes all aspects of planning, engineering, construction, operations, and maintenance.

3.1 REGULATORY REQUIREMENTS FOR LEGAL AUTHORITY ELEMENT The regulatory requirements for the Legal Authority Element of the SSMP are summarized as follows:

The City and District must demonstrate, through collection system use ordinances, service agreements, or other legally binding procedures, that they possess the necessary legal authority to:
a) Prevent illicit discharges into its wastewater collection system (examples may include infiltration and inflow (I/I), storm water, chemical dumping, unauthorized debris and cut roots, etc.);
b) Collaborate with storm sewer agencies to coordinate emergency spill responses, ensure access to storm sewer systems during spill events, and prevent unintentional cross connections of sanitary sewer infrastructure to storm sewer infrastructure; c) Collaborate with storm sewer agencies to coordinate emergency spill responses, ensure access to storm sewer systems during spill events, and prevent unintentional cross connections of sanitary sewer infrastructure to storm sewer infrastructure; d) Require that sewers and connections be properly designed and constructed; e) Ensure access for maintenance, inspection, or repairs for portions of the lateral owned or maintained by the City and/or District;
f) Limit the discharge of fats, oils, and grease (FOG), as well as any other debris that may cause blockages; and
g) Enforce any violation of its sewer ordinances, service agreements, or other legally binding procedures; and
h) Obtain easement accessibility agreements for locations requiring sewer system operations and maintenance, as applicable.

SANITARY SEWER MANAGEMENT PLAN

3.2 LEGAL AUTHORITY DISCUSSION
In 1985, the City of Ukiah adopted Ordinance No. 845 as the City’s Wastewater Ordinance. The ordinance provides rules and regulations for the use and construction of sanitary sewer facilities installed, altered, and repaired within the City. This ordinance is codified in Division 4, Utilities Chapter 2 Sewers, Sections 3700.00 et seq, of the Ukiah City Code. The ordinance is found online at www.codepublishing.com/CA/Ukiah/ (updated as needed). Within the ordinance, the City has the following legal authorities:
 Assign responsibility for maintenance of sewer laterals;  Prevent unlawful sewage disposal into the public sewer collection system;  Require proper design and construction of sewers and connections;  Ensure access for maintenance, inspection and repairs;  Limit discharge of fats, oils, and grease (FOG) and other debris; and  Enforce violation of its sewer ordinance, as appropriate.

Also in 1985, the Ukiah Valley Sanitation District adopted Ordinance No. 12. This ordinance builds upon District Ordinance No. 1 to serve as the District’s Wastewater Ordinance. Like the City’s ordinance, Ordinances No. 1 and No. 12 establish the District’s authority within its boundaries to regulate sewage disposal in public and private systems, maintain those systems, promulgate connection and lateral requirements, promulgate public sewer construction requirements, oversee uses of its sewer facilities, establish fees and service charges, issue permits, and carry out enforcement. Ordinance Nos. 1 and 12 are available online at https://www.uvsd.org/ordinances?rq=ordinance.

As the City and District share use of the sanitary sewer collection and treatment system, both parties entered into a Participation Agreement in 1995. This Agreement is, in part, to ensure consistency in the design, engineering and treatment requirements of the two jurisdictions. This Agreement is discussed in greater detail in Section 3.3 below.

3.2.1 Sewer Lateral Maintenance Responsibility
Per Article 5, Section 3704.8, of City Wastewater Ordinance and Article 5, Section 5.8, of the District Wastewater Ordinance, property owners are responsible for maintaining the sewer line between the foundation wall of any building and its connection at the main sewer. This portion of the sewer system is referred as a “side lateral”. Article 18 of the City’s ordinance and Section

5.9 of the District’s ordinance provide requirements for the testing, repair, and replacement of all sewer laterals within City and District areas served by the wastewater treatment plant.

Moreover, the City and the District have a Private Sewer Lateral Testing Program, effective January 2007, which requires the cleaning, inspection and testing of sewer laterals connected to public sewers. This program includes residential, multi-family residential, commercial or industrial users and is effective upon the occurrence of events outlined in the program standards. A copy of this program is presented in Appendix D.

CITY OF UKIAN AND UKIAH VALLEY SANITATION DISTRICT August 2025 | 11

SANITARY SEWER MANAGEMENT PLAN
The City and the District are considering updating the Wastewater Ordinance to split the responsibility for the laterals at the public right of way (whereas the City/District would be responsible for the lower laterals); however, at the time of this SSMP update, there is no projected timeline for this potential policy change.

3.2.2 Prevention of Illicit Discharges
Article 3 of both the City’s and District’s wastewater ordinances prohibits illicit discharges. It is the general intent of the City and District to regulate and control the quantity and quality of discharges into the sewer system so that they will not adversely affect the collection and treatment system, as well as human health and environment. Per Articles 3 and 7 of both wastewater ordinances, it is prohibited to discharge the following into public sewer system:
 Effluent from onsite systems (i.e., septic tank, cesspool, etc.), rainwater, storm/surface or subsurface water;
 Swimming pool direct connection drains;
 Cooling water;
 Commercial/industrial wastes in excess of their permit allowance; and  Any waste disposal containing explosive or flammable substances, corrosive materials, petroleum, solids and garbage, and toxic substances. Inclusive lists of the prohibited wastes are found in these articles of the wastewater ordinances.

Article 4 of both the City’s and District’s wastewater ordinances allows for private sewage disposal systems where public sewer is not available. However, issuance of a written permit by the City Public Works and/or County Health Officer is required. The type, capacities, locations and layout of a private sewage disposal system shall comply with all requirements of the California Department of Public Health and of the Mendocino County Health Officer. The City has the legal authority to inspect the work at any stage of construction for any private sewage disposal system. Once a public sewer becomes available within 200 feet of a property, a direct connection shall be made to the public sewer in compliance with the ordinances, rules, and regulations of City, and private sewage disposal facilities shall be abandoned.

3.2.3 Require Proper Design and Construction of Sewers and Connections Section 200 of the City’s Standard Plans covers the construction of sanitary sewers in the City and the District. These standards ensure that new sewer lines and connections are properly designed and constructed. The Standard Plans can be accessed in the City’s website (https://cityofukiah.com/public-works/#forms).

The Standard Plans are adjunct to the City’s and District’s wastewater ordinances, which describes authorities and regulations for proper design and construction of private sewer laterals (Article 5 in both) and public sewer system (Article 6 in both). The wastewater ordinances require:
 A written permit, payment of all connection fees, and furnishing of all required bonds before constructing, extending or connecting to any public sewer system. (Article 5,

CITY OF UKIAN AND UKIAH VALLEY SANITATION DISTRICT August 2025 | 12

SANITARY SEWER MANAGEMENT PLAN
Section 3704.1 [City] and Section 5.1 [District]); Article 6, Section 3705.1 [City] and Section 6.1 [District])
 Compliance with the standards for the design and construction of sewers within the City in accordance with the Standard Improvement Details (Standard Plans) adopted by the City. (Article 6, Section 3705.2[City] and Section 6.2 [District])  Submittal of plans, profiles and specifications, complying with all applicable ordinances, rules and regulations of the City, prepared by a civil engineer registered in the State of California, to obtain a permit for public sewer construction. (Article 6, Section 3705.3 [City] and Section 6.3 [District])
 Submittal of “As-Built” drawings showing the actual locations of all mains, structures, wyes, laterals, and other changes to the construction drawings prior to the City’s final acceptance of the work. (Article 6, Section 3705.8[City] and Section 6.8 [District]) Testing of all sewerage works prior to the City’s final acceptance of the work. (Article 6, Section 3705.9[City] and Section 6.9 [District])
 Installation of separate and independent sewers for every structure. (Article 5, Section3704.3[City] and Section 5.3 [District])
 Installation of clean-outs for all building laterals. (Article 5, Section 3704.5[City] and Section 5.5 [District])

3.2.4 Ensure Access for Maintenance, Inspection and Repairs Article 6, Section 3705.5, of the City Wastewater Ordinance and Article 6, Section 6.5, of the District Wastewater Ordinance states that all portions of a public sewer extension shall have “a proper easement or grant of right-of-way having a minimum width of ten feet (10') sufficient in law to allow the laying and maintenance of such extension or connection.” The City and District also have the right of entry to any properties for the purpose of inspecting and protecting the public sewer system per City Wastewater Ordinance Article 7, Section 3706.7, Paragraph J, and District Wastewater Ordinance Article 7, Section 7.7, Paragraph J (paraphrased):
“The Director of Public Works, and other duly authorized employees of the District/City bearing proper credentials and identification, shall be permitted to enter all properties served by the City for the purpose of inspection, observation, measurement, sampling, and testing in accordance with the provisions of this ordinance.”
The Sewer Standard Plans do not specifically require vehicular access to all manholes and cleanouts; however, easement provisions allow access where necessary. Through its design review process, the City and District requires such access as common engineering practice. See the Sanitary Sewer Standards of Practice (SOP) in Appendix D for more information.

3.2.5 Limit Discharge of Pipe Blocking Substances
Ordinance No. 1, which regulates the use of the public sewer and drains was adopted by the District in 1958. Section 206 concerns the disposal of wastes and prohibits the discharge of any objectional waste. Objectionable waste is defined as any wastes, that, in the City’s or the

CITY OF UKIAN AND UKIAH VALLEY SANITATION DISTRICT August 2025 | 13

SANITARY SEWER MANAGEMENT PLAN
District’s opinion, can harm the sewers or sewage treatment process. This includes pipe-blocking substances such as FOG, debris, rags, and wipes.

On October 1, 2008, the City adopted Ordinance No. 1111, which amended Article 17 of the City Wastewater Ordinance. The ordinance was prepared and adopted in accordance with the City’s 2006 National Pollutant Discharge Elimination System (NPDES) permit in order to control FOG.

The City’s ordinance provides a framework for the review, permitting, construction, inspection, and ongoing maintenance of facilities that create and discharge FOG into the public sewer system. Article 17, Section 3798 C (d), of Ordinance 1111 states the following:
“No User may intentionally or unintentionally allow the direct or indirect discharge of any petroleum oil, non-biodegradable cutting oil, mineral oil, or any Fats, oils, or Greases of animal or vegetable origin into the POTW (Publicly Owned Treatment Works) system in such amounts as to cause interference with the collection and treatment system, or as to cause pollutants to pass through the treatment works into the environment.” Ordinance No. 1111 is codified in Article 17.5, Section 3798A.7 and coupled with Article 7, Part 3706.1, which prohibits discharge of any waste that could cause damage to the sewer system or cause extra collection, treatment, or disposal cost. Additionally, Article 7, Part 3706.4 prohibits discharge of solids in quantities or of such size capable of causing obstruction to the flow in the sewer system.

Ordinance No. 1111 is applicable within the City limits, including those areas previously within the District’s jurisdiction. In April 2009, Ordinance No. 1114 was adopted to remove the City/District overlap area from the City’s jurisdiction. District Grease Interceptor Ordinance No. 28 was adopted on December 14, 2006, and is applicable for all portions of the District area. A copy of Ordinances No. 1111 and No. 1114 are available at www.codepublishing.com/CA/Ukiah/ and Ordinance No. 1 and 28 is available at www.uvsd.org/ordinances.

The City’s sewer pipe blockage control program is further discussed in Element 7 of the SSMP.

3.2.6 Enforcement Measures
Article 11 of both the City’s and District’s wastewater ordinances describes different enforcement measures that are available for violations of the sewer ordinances. At first, written notice stating the nature of the violation is provided to any person found to be violating and a reasonable time limit – from twenty-four (24) hours to ten (10) working days – is given for the satisfactory correction. Upon noncompliance with an enforcement action, a public nuisance may be declared which would potentially lead to the violating user being disconnected from the sewer mains. Costs associated with disconnection and reconnection would be paid by the user.

Violations are also punishable by monetary fines, imprisonment, or both.

3.3 AGREEMENT WITH SATELLITE AGENCIES
Article 10 of the City Wastewater Ordinance allows the connection of satellite facilities upon execution of an agreement between the City and the satellite agency. The City owns and manages a sewer collection system within its corporate limits and manages the collection

SANITARY SEWER MANAGEMENT PLAN
system owned by the District. The District’s collection system serves both unincorporated areas of Mendocino County and portions of the City that were annexed in the last 30 years.

The City has had a contractual agreement with the District that affects both the treatment plant and sewer collection system since the adoption of the “Participation Agreement between the City of Ukiah and the Ukiah Valley Sanitation District” on July 19, 1995. A copy of the agreement and its amendments can be provided upon request. A few key items in this agreement are as follows:
 The agreement has an initial term of thirty (30) years.  The City acts as the agent for all District operation and maintenance funds.  The City is responsible for the operation, maintenance and repair of the District’s trunk sewer and sewage collection system, including all sewer mains constructed within the District.
 The City is responsible for the construction of all required private sewer laterals for public sewer extensions and the inspection of sewer lines installed by subdivision developers.

The basic agreement was amended on March 24, 1999, to address annual costs and budgets. A second amendment was signed by the City and the District on December 15, 2005. Amendment No. 2 allocated new sewer service units within each agency’s boundary and described cost sharing for wastewater treatment plant upgrades. No additional amendments have been established since the 2005 amendment.

The City does not have any agreements with stormwater agencies since the City also manages stormwater-related efforts in the service area. As previously noted, there is no underground stormwater infrastructure within the District boundary. 4 OPERATION AND MAINTENANCE PROGRAM
This element of the SSMP provides a summary of the City's O&M Program for the collection system, which includes both City and District facilities.

4.1 SEWER SYSTEM MAPPING

4.1.1 Regulatory Requirements for Sewer System Map
The City and District must maintain an up-to-date map of the sanitary sewer system, showing all gravity line segments, manholes, pumping facilities, pressure pipes, valves, and applicable storm water conveyance facilities. As well as procedures for maintaining and providing State and Regional Water Board staff access to the map(s).

4.1.2 City and District Sanitary Sewer System Base Maps Maps used by City field crews divide the collection system into a set of maps that are bound with plywood and kept at City offices. This map set shows the location of all sewer mains,

CITY OF UKIAN AND UKIAH VALLEY SANITATION DISTRICT August 2025 | 15

SANITARY SEWER MANAGEMENT PLAN
manholes, laterals, pumping stations and pressurized sewer lines (force mains). An overall sewer map completes the set and clearly distinguishes between the sewer collection lines owned by the City and those owned by the District.

In addition, the City maintains an AutoCAD-based Geographic Information System (GIS) database for mapping. The GIS database includes detailed information for all collection system components (District and City), such as identification numbers for manholes, distances between manholes, pipe diameters, and pump station information. However, the GIS database does not include the valve information. The City’s Engineering Division is responsible for continuous updates to the GIS database, with new maps provided as needed. Updates to maps are generally made when:
 Facilities are added through public works or private development projects;  System components are rehabilitated; and
 When corrections are identified through field work.

Electronic maps generated from the GIS database are considered to be real time documents and can be printed for use by field operators and engineering staff at any desirable scale to show any necessary details. Figure 1shows a map of the City and District sewer collection systems, and is an example of the mapping capabilities of the GIS database.

Upon receiving a request from State and/or Regional Water Board staff for access to the City’s sanitary sewer maps, City staff can provide a copy of the most up-to-date map in an easily accessible format.

4.1.3 City and District Storm Drain System Base Maps
The City and District understand the link between spills and their potential impact on adjacent receiving water bodies. City staff have been trained to capture a spill if it has entered the storm drain system. The City can use its printed maps at the City offices or GIS maps to identify the storm drainage system inlets relative to the sewer collection system.. In order to enhance its Spill Emergency Response Plan (SERP, Element 6) by minimizing the number of potential blind spots in the sewer and storm system, the City has verified the locations of storm drain outlets along Orr Creek and other receiving water bodies adjacent to the sewer collection system to ensure accessibility to the outfalls. The City completed this effort in 2008 with the aid of Global Positioning System (GPS) equipment and field inspections.

4.2 PREVENTIVE OPERATION AND MAINTENANCE

4.2.1 Regulatory Requirements for Preventative Operation and Maintenance This section of the SSMP must describe the scheduling system and data collection system for preventive operation and maintenance activities conducted by staff and contractors.

The scheduling system must include:
 Inspection and maintenance activities;

CITY OF UKIAN AND UKIAH VALLEY SANITATION DISTRICT August 2025 | 16

SANITARY SEWER MANAGEMENT PLAN
 Higher-frequency inspections and maintenance of known problem areas, including areas with tree root problems;
 Regular visual and closed-circuit television (CCTV) inspections of manholes and sewer pipes.

The data collection system must document data from system inspection and maintenance activities, including system areas/components prone to root-intrusion potentially resulting in system backup and/or failure.

4.2.2 Preventive Maintenance Program
In order to monitor and maintain the entire City and District sewer collection system, the City has established O&M practices that collectively form the City’s Preventive Maintenance Program. This program is targeted at identifying and eliminating sanitary sewer overflows and blockages. In addition to knowledge and experience with various portions of the sewer collection system, the City’s Preventive Maintenance Program activities include the following:
 Routine monitoring and cleaning of the collection system and its lift stations; Ongoing evaluation of a Sewer Maintenance List, including “Hot Spots”;  CCTV inspection; and
 Frequent updates to the parts inventory, including critical components.

The Organizational Chart provided in SSMP Element 2 shows the various personnel responsible for field maintenance of both the City and District facilities.

4.2.2.1 Sanitary Sewer System Operation and Maintenance City crews conduct general cleaning of the entire collection system on an annual basis and clean known critical areas included in the “Sewer Maintenance List” (Appendix C) more frequently.

The City and District experience few spills annually and in general, the volume and frequency of spills has decreased in recent years. The vast majority of spills do not reach surface waters. All spills are reported to the California Integrated Water Quality System (CIWQS). Statistics and details on the frequency and volume of spills experienced to date are presented in the most recently conducted SSMP Audit.

The City has eight maintenance personnel that are assigned to perform O&M of the sewer collection and water system. Two one-ton service trucks and three vactor trucks are utilized to clean pipes and manholes, remove blockages, and respond to spills. The critical area sewer pipes (approximately 23,000 feet), , also known as “Hot Spots”, are given high priority, and are monitored, maintained and cleaned at least once a month. Appendix C includes a City CCTV inspection form and sample inspection forms. City crews use these forms to assess the condition of pipelines and manholes during routine inspections or following a spill.

The primary causes for blockages and spills in the sewer collection system have been attributed to accumulation of FOG, roots, and constituents such as heavy-duty shop towels and disposable diapers. The frequency and volume of spills have significantly decreased in recent years. The

CITY OF UKIAN AND UKIAH VALLEY SANITATION DISTRICT August 2025 | 17

SANITARY SEWER MANAGEMENT PLAN
Sewer Maintenance List has been incorporated into the City’s GIS database in order to better track and map maintenance locations and a corresponding table with maintenance locations in Appendix C. Hydraulic capacity issues are discussed in Element 8 of the SSMP.

Currently, the City has a manual work order system for both routine and targeted operation and maintenance activities. Field crews report to the Water/Sewer Maintenance Supervisor for scheduled operation and maintenance tasks for both types of activities. City personnel and an after-hour emergency phone line are available to receive customer phone calls 24 hours a day, 7 days a week for both City and District customers. The City has also been working closely with the District to address customer complaints and requests.

The “Sewer Maintenance List” is kept in the Water/Sewer Maintenance Supervisor’s office and updated as yearly and monthly cleaning is completed. City crews provide input on the date and time of cleaning as well as the debris type and the severity of the blockage. The Sewer Maintenance List has been developed over time based on field observations during routine and targeted inspections of the collection system. The City merged this list, work order documents, manhole and CCTV inspection forms (Appendix C) and record information for the collection system (i.e., pipe, manhole, and pump station metrics) and the City’s GIS database into iWorq, a city management system with field data and schedules from the O&M Program.

CCTV inspection is used for overall assessment of both the City and District systems and provides useful visual information where problem areas are located between manholes. This O&M Program component is conducted in part to comply with system assessment goals outlined in the City and District’s agreements with Northern California River Watch (River Watch). In addition to general CCTV inspection of the entire collection system, video inspection is used for specific condition assessment of the collection system and for system review following spill events. City crews correct problems that are identified through CCTV inspection and complete the repairs in order of priority. Priority is currently determined based on the observed severity of each problem area and its impact on the collection system and environment. The City’s CCTV inspection program is further described in Section 4.5 below.

4.2.2.2 Pump Station Operation and Maintenance
There are three sanitary sewer pump stations located in the City and District service area (see Figure 1). Each pump station includes two pumps with control systems for manual operation during a power loss or other emergency situation. Pump stations are currently monitored by daily visual inspections. The City does not currently utilize a Supervisory Control and Data Acquisition (SCADA) system to remotely operate the pump stations. The City recently installed a telemetry system for each pump station (CVD-2000 Cellular Voice Dialer) to remotely notify the City of pump station alarms.

The City utilizes portable pumps located at the WWTP if bypass pumping is required within the collection system. These pumps are not capable of bypass pumping at the pump stations. Pump stations do not have back-up power systems (i.e., generators); the City is evaluating the need for

CITY OF UKIAN AND UKIAH VALLEY SANITATION DISTRICT August 2025 | 18

SANITARY SEWER MANAGEMENT PLAN
a portable standby power generator that could operate a pump station in an emergency situation.

Pump stations are cleaned at least monthly by City field personnel. The City follows the recommended pump maintenance schedule from the pump manufacturers. Comprehensive maintenance of pump station piping, valves and other equipment is also performed by the City according to the pump station O&M manuals kept in the Water/Sewer Maintenance Supervisor’s office. Both of the City’s one-ton service trucks have mounted electric cranes with a service rating of 2,700-pounds that are capable of removing and servicing pumps or other heavy equipment.

A complete list of the City’s rolling stock and field equipment is maintained and is available to City staff. This list is reviewed and updated frequently to ensure spare parts are always available in case of an emergency.

4.3 REHABILITATION AND REPLACEMENT PLAN
Finally, the rehabilitation and replacement plan should include a capital improvement plan that addresses proper management and protection of the infrastructure assets. The plan shall include a time schedule for implementing the short and long term plans together with a schedule for developing the funds needed for the capital improvement plan.

4.3.1 Sanitary Sewer System Inspection and Condition Assessment The sewer collection system is susceptible to damage and blockages due to structural problems such as joint separation, debris buildup from roots, grease, and paper towels. Further, the collection system has reduced hydraulic capacity in various locations due to infiltration and inflow (I/I). The target of inspection and condition assessment is to locate areas within the collection system impacted by these factors and make corrections as needed.

The City’s previous sewer master plan document, Wastewater Collection System and Treatment Improvements, was conducted by Kennedy Engineers in 1978. The 1978 study identified a number of possible sources of I/I, including uncapped plumbing, residential lateral leaks, manhole leaks, and cracked pipes. That study proposed no major reductions in, or remedies for, I/I at that time. However, based on the overall findings of the report, the City chose to expand and improve its wastewater treatment plant to accommodate future anticipated flows.

The City uses its own equipment and staff to perform collection system inspections. The City video inspects the entire sewer collection system annually, including District facilities, or more often for Hot Spots, and maintains the “Sewer Maintenance List” for Hot Spots and “Maintenance and Repairs” list for general inspections. These records are grouped by year and are kept in the Water/Sewer Maintenance Supervisor’s office. The records include information regarding the date and time of the cleaning, the length of the pipes that have been inspected, and all maintenance procedures. There is also a summary page at the beginning of each year’s data that shows the total number of sewer lines that have been cleaned, lined, repaired and replaced as well as the number of new lines constructed during that year.

CITY OF UKIAN AND UKIAH VALLEY SANITATION DISTRICT August 2025 | 19

SANITARY SEWER MANAGEMENT PLAN
The manhole inspection form provided in Appendix C is an example of the type of paperwork completed by field personnel during collection system inspection. An example of a closed circuit television video (CCTV) inspection report from the City of Los Angeles for pipeline inspection is also included in Appendix C.

4.3.1.1 CCTV Inspection
Beginning in 2006, the City started to assess the physical condition of the entire sewer collection system, including District facilities, by CCTV inspection performed by City personnel. The inspection has been performed with standard CUES Granite XP software which is certified by the National Association of Sewer Service Companies (NASSCO) Pipeline Assessment and Certification Program (PACP). Problem areas are generally repaired by City crews following identification during CCTV inspection.

The records of the CCTV inspections are collected in external hard drives and can be copied to a DVD for viewing and record keeping. Print outs from the software are kept in individual binders for each year and include descriptions of each observed structural or maintenance problem as well as other features of the pipe reach such as lateral connections. CCTV videos and reports can also be added to a GIS database. The database has the capability to create links between stored files such as videos, pictures, and reports. These files would be accessed directly from the database or as “Hot Links” within an electronic map. A Hot Link is essentially a hyperlink that allows a user to click on a point in the map (i.e., pipe, manhole, pump station, etc.) and be directed to the external file.

To date, the City has completed CCTV inspection for 100 percent of the City and District’s sewer pipes and plans to have the entire collection system inspected on a regular basis.

4.3.1.2 Condition Assessment
Visual inspection of the collection system is performed during manhole and CCTV inspection, occasionally resulting in repair and/or replacement projects; however, condition assessment using NASSCO defect categories and PACP rating procedures is not planned until a second CCTV inspection is conducted. Once a second round of CCTV inspections is completed, ratings will be incorporated into the City’s GIS System database where results can be evaluated to determine rehabilitation and replacement needs, and recommendations made for inclusion in annual budgeting. The City’s CUES Granite XP CCTV software is compatible with NASSCO forms and procedures. This link between programs will provide the City with a smooth transition to NASSCO standards and reporting capabilities. Pipes and manholes will be defined with a “good, moderate, and poor” or a numerical rating system. The scoring information will be linked to the GIS System database and used as a tool to prioritize the City’s rehabilitation and replacement projects. See Appendix C for a summary of NASSCO defect categories and PACP rating procedures for pipelines and manholes.

4.3.2 Asset Management Planning
The City has the necessary ArcView GIS software and AutoCAD files to compile and maintain a database for its sewer collection system. The GIS System database for the collection system includes the following system metrics for pipes, manholes, and pump stations:

CITY OF UKIAN AND UKIAH VALLEY SANITATION DISTRICT August 2025 | 20

SANITARY SEWER MANAGEMENT PLAN
 Pipe descriptions, dimensions, and age;
 Manhole descriptions, dimensions, and age; and
 Pump station equipment descriptions and age.

The PACP rating system can be applied once this information for the collection system pipes is added to the database. A similar rating system can be developed by the City for manholes and pump stations. Rehabilitation and replacement projects are identified by the City based on findings from maintenance and inspection efforts.

CIP projects can include both rehabilitation and replacement projects. A common definition for “rehabilitation” is a City sponsored project designed to replace or repair any portion of the sewerage conveyance system including, but not limited to; sewer mains, manholes, and connections to the main sewer line. Replacement projects could be integrated with rehabilitation, but could also include more substantial capital improvement projects.

4.3.3 Rehabilitation and Replacement Projects
Currently, the City and District prepare annual rehabilitation and replacement (R&R) projects based on historical sewer back-ups, visual inspection, and the age of the sanitary sewer collection system. Projects scheduled through the end of FY 2025-2026 include water main replacements throughout the City which are to be performed in conjunction with street improvement projects, replacing the 16-inch steel water and sewer main from PZ1 to Bush Street ($1,500,000) and upgrading the Vichy Springs lift station ($400,000). The estimated CIP cost includes all project costs such as planning, design, construction, and construction management. More information about R&R projects, including budget and funding is provided in Element 8 of the SSMP.

4.3.4 Sewer Lateral Testing Program
In 2007, the City established a “Sewer Lateral Testing Program” (Appendix C) to reduce inflow and infiltration into the sewer collection system. City Ordinance No. 1105 was later adopted on February 6, 2008, to facilitate the proper maintenance of private sewer laterals (available at www.codepublishing.com/CA/Ukiah/). Article 18, Part 3799.1(B) Ordinance states the following:
“It is the policy of the City to reasonably prevent infiltration, exfiltration and better protect the Sewer Treatment Plant and the environment by requiring a reasonable program of inspection, testing, and if necessary, repair and replacement, or private sewer laterals.”
District Ordinance No. 30 was adopted on January 30, 2008, and effectively mirrors City Ordinance No. 1105. This ordinance is available at https://www.uvsd.org/ordinances.

The ordinances provide the City and District with the authority to require rehabilitation and replacement for sewer laterals and a framework for ensuring the completion of required work. If repairs are not completed within a required time frame, the City (or District) may complete the work and add a surcharge to the property’s utility account. Sewer laterals are required to be cleaned and tested for the following occurrences:

CITY OF UKIAN AND UKIAH VALLEY SANITATION DISTRICT August 2025 | 21

SANITARY SEWER MANAGEMENT PLAN
 Following a sanitary sewer overflow generated from the private lateral; Upon discovery of an illegal connection or discharge;
 Upon application for a building permit where the value of work exceeds $100,000;  For plumbing fixture additions having two or more fixture units (per California Plumbing Code);
 Addition of bedrooms;
 In conjunction with an R&R project to which the lateral is connected;  Following a Qualifying Sewer Lateral Service Call; and  For laterals serving parcels within 100 feet of a waterway that is declared to be impacted by the sewer system.

The ordinances include time frames for cleaning, inspecting, and testing based on the type of occurrence. The ordinances also include a requirement that plumbers, contractors, and other persons be appropriately licensed to perform lateral testing and repair/replacement within the City and District.

To help reduce the cost of lateral repairs and testing, the City Council enacted a grant program wherein up to $2,000 is available per lateral repair/replacement. To apply for the grant included in Appendix C, customers should fill out a “Sewer Lateral Replacement Grant Program Application” and submit to the Public Utilities Department.

4.4 CONTINGENCY EQUIPMENT AND REPLACEMENT

4.4.1 Regulatory Requirements for Contingency Equipment and Replacement Inventories
The City and District must provide equipment and replacement part inventories, including identification of critical replacement parts.

4.4.2 Parts and Equipment Inventory
The City uses QuickBooks software to maintain an inventory of spare and/or replacement parts that can be used for either the City or District system. The inventory is used to track both standard and critical parts for the collection system and pump stations. Appendix C includes a simplified inventory inquiry that shows the part item number, description, and quantity on hand.

The program also has the capability to track items such as order numbers, order backlogs, and expected delivery dates.

The City’s Public Utilities Purchasing Department regularly updates the inventory to maintain a current record of available parts. Updates to the inventory are provided by personnel in the maintenance department using an on-going “Charge-Outs” list. The inventory does not specifically distinguish between standard and critical parts, but rather a reorder point is established for each critical item so that the City has resources available for immediate response to problem areas and spills. Upkeep of the inventory requires collaboration between City departments, as some parts are used infrequently and others during routine maintenance. Also,

CITY OF UKIAN AND UKIAH VALLEY SANITATION DISTRICT August 2025 | 22

SANITARY SEWER MANAGEMENT PLAN
some parts are only reordered when the quantity on hand is exhausted, whereas others may be ordered with a substantial lead time for less common parts.

Pump stations and the trunk lines are considered critical components of the sewer collection system. Standardization of equipment and parts is an ongoing process and requires budgeting.

In general, non-standard parts are replaced with standardized parts during maintenance and repairs. Parts for new system components such as the telemetry system equipment for each pump station are standardized at the time of purchase.

All sewer maintenance equipment and replacement parts, including small tools, pipe and pipe fittings, and manhole components, are stored at the City’s Corporation Yard (Corp Yard). The rolling stock described in Section 4.4.3 and provided in the City’s SERP Appendix A is also stored at the Corp Yard.

4.4.3 Contingency Equipment
Rolling stock and equipment is used for emergency operations as well as for routine operation and maintenance activities. CCTV equipment is used to inspect a pipe following repairs. The City’s jetter/rodder and vactor trucks are utilized to remove blockages and assist with the containment and cleanup of a spill. The electric crane mounted on each service truck is used to lift heavy equipment and could be used as a winch. Emergency generators and portable pumps provide temporary power and bypass capability.

As discussed in Section 4.2.2.2, the City uses portable pumps kept at the WWTP to provide bypass pumping within the collection system. The new telemetry equipment provides the City with enhanced notification of alarms and problems at each pump station. The City is also currently evaluating the need for a portable standby power generator that could operate a pump station in an emergency situation.

The City’s SERP Appendix A also includes a list of the local vendors, suppliers and contractors who can provide rental equipment during a spill event or if construction conditions warrant outside resources (i.e., shoring, dewatering). Pace Supply is used as the City’s emergency contact during non-working hours. Contact information is posted on the Water/Sewer Maintenance Supervisor’s board and provided below.

Pace Supply Emergency Phone Numbers (Lucas):
(707) 391-7456 [Mobile] and (707) 467-9110 [Home]
The City has not experienced the need to establish a mutual assistance program with neighboring agencies, though this type of program could be implemented in the future based on system demands and the availability of equipment and personnel.

4.5 TRAINING

4.5.1 Regulatory Requirements for Training
The City must provide in-house and external training on a regular basis for staff in sanitary sewer system operations, maintenance, and require contractors to be appropriately trained. The training must cover:

CITY OF UKIAN AND UKIAH VALLEY SANITATION DISTRICT August 2025 | 23

SANITARY SEWER MANAGEMENT PLAN
 The requirements of the 2022 WDR SSS;
 Spill Emergency Response Plan procedures and practice drills;  Skilled estimation of spill volume for field operators; and  Electronic CIWQS reporting procedures for staff submitting data.

4.5.2 Sanitary Sewer System Staff Training
Job descriptions prepared by the City’s Human Resources Department for all operation and maintenance positions are based on CWEA Collection System Maintenance Certifications requirements. All of the current sewer operation and maintenance staff are CWEA-certified. The City has two field personnel working with CCTV equipment who are NASSCO-PACP trained and certified. This training and certification provides the basis for data collection and condition assessment that will be used in the City’s Asset Management Plan.

The City budget includes annual conference and training expenses for its sewer operation and maintenance staff. An example of personnel training and certification for the Water/Sewer Maintenance Supervisor is provided below:
 California OSHA Competent Person
 Confined Space Entry
 Work Zone Safety
 CWEA – Grade III, Collection System Maintenance
 CWEA – Spill-WDR Compliance Workshop Electronic Reporting Staff training is also done through mentoring, in-house classes and on-the-job training between staff. When new equipment is acquired, the City utilizes the equipment supplier to provide training for appropriate personnel. The Water/Sewer Maintenance Supervisor makes sure the employees have the necessary skills to perform the operations and maintenance required by going over the standard operating procedures for all sewer operation and maintenance crew.

Human Resources reviews job descriptions against CWEA requirements and informs the supervisor if training or recertification is needed. The City enforces a six-month probationary period for collection staff employees so that only reliable, trained personnel are hired on a fulltime basis.

Contractors that perform work within the City or District are also required to meet the minimum safety requirements set forth by California OSHA and any training guidelines set forth by CWEA for collection system work.

4.5.3 Outreach to Plumbers and Building Contractors
The City implements an outreach program to educate commercial entities involved in sewer construction or maintenance about the proper practices for preventing blockages in private laterals. The City regularly updates its website (www.cityofukiah.com) to provide local plumbers and building contractors with a convenient resource for the City’s sewer policies, standards, and

CITY OF UKIAN AND UKIAH VALLEY SANITATION DISTRICT August 2025 | 24

SANITARY SEWER MANAGEMENT PLAN
procedures. These documents are also available for distribution at the City or can be discussed by contacting the City’s Public Works Department. More discussion about City standards is presented in Element 5 of the SSMP.

The City is also a member of Russian River Watershed Association (RRWA) which has prepared an outreach fact sheet titled “Good Plumbing Practices” to notify plumbing contractors about the potential impact of their work on the City’s sanitary sewer system. The RRWA outreach fact sheet is attached in Appendix C.
5 DESIGN AND PERFORMANCE PROVISIONS
The City and District believe that proper installation of sanitary sewer facilities is essential to proper operations. To ensure proper installation, this Sewer System Management Plan addresses the following design and performance provisions:
 Standards for Installation, Rehabilitation and Repair  Standards for Inspection and Testing of New, Rehabilitated, and Repaired Facilities Element 5 provides a summary of the City and District wastewater collection system design and construction standards.

5.1 STANDARDS FOR INSTALLATION, REHABILITATION AND REPAIR

5.1.1 Regulatory Requirements for Standards for Installation, Rehabilitation and Repair
The regulatory requirements for the “Standards for Installation, Rehabilitation, and Repair” subsection of the Design and Performance Provisions Element of SSMPs are summarized as follows:
 Updated design criteria, and construction standards and specifications, for the construction, installation, repair, and rehabilitation of existing and proposed system infrastructure components, including but not limited to pipelines, pump stations, and other system appurtenances. If existing design criteria and construction standards are deficient to address the necessary component-specific hydraulic capacity as specified in Element 8 (System Evaluation, Capacity Assurance and Capital Improvements), the procedures must include component-specific evaluation of the design criteria.

5.1.2 Standards for Installation, Rehabilitation and Repair Article 6 of both the City’s Wastewater Ordinance (Division 4, Chapter 2) and the District’s Wastewater Ordinance (https://www.uvsd.org/ordinances) include requirements for public sewer construction application, permit, easements, plans, profiles, and specifications prior to the acceptance of the sewer work by the City or District. Design flow and capacity criteria for sewer mains and trunk lines are presented in Element 8 of the SSMP.

All public sewer mains within the City and District are designed and constructed by the City, District, or contractors to the City or District. The City of Ukiah Standard Plans Section 200 –

CITY OF UKIAN AND UKIAH VALLEY SANITATION DISTRICT August 2025 | 25

SANITARY SEWER MANAGEMENT PLAN
Sewer establishes minimum standards for the design and construction of public sanitary sewers and guides contractors working on public sanitary sewer projects. The complete Standard Plans document is available on the City’s website (https://cityofukiah.com/public-works/#forms, Public Works Department Downloads webpage). Hard copies may also be purchased at the City Clerk’s office located at 300 Seminary Avenue. A description of the various standard drawings is provided in the Sewer System Standards of Practice (SOP) document in Appendix D and generally discussed below. The District has adopted and enforces the City’s standards.

Sewer Standard Drawing Nos. 210 and 213 describe the general design criteria for construction of new sewer laterals, including pipe materials and required fittings, minimum pipe sizes and slopes, pipe depths, and requirements for connection to sewer mains. Drawing Nos. 215 and 218 describe design criteria used for private force main laterals and multi-sewer connections that would be seldom used in new construction and allowed only at the discretion of the City Engineer or District Manager.

Sewer and water lateral separation requirements are explained in Section 3702.6 of the City’s Wastewater Ordinance and Section 3.6 of the District’s Wastewater Ordinance. Trench details for sewer mains and service laterals – including the trench width, trench backfill, and compaction requirements – are presented in Sewer Standard Drawing No. 220. Further, Sewer Standard Drawing No. 222 describes the required joint trench for sewer and water laterals.

These Sewer Standard Plans were originally prepared by the City in 1987 and updates were made in 1996. The City’s Public Works Department guides any potential updates to the standards.

For rehabilitation and repair projects, the City and District have also been using “Standard Plans for Public Works Construction” (known informally as the “Greenbook”), prepared by the American Public Works Association (APWA) and the Associated General Contractors of California. The City and District have adopted Part 5 – System Rehabilitation as the standard specifications for all rehabilitated and repaired sewer assets. The City and District may opt to add project-specific specifications related to sewer rehabilitation and repair projects on a caseby-case basis.

The City and District own and operate three pump stations and do not anticipate any additional pump stations to be built. Therefore, design standards and construction specifications for pump stations and associated force mains will be developed on a project-specific basis as the need arises.

Beyond the Sewer Standard Plans, the City and District do not have formal sewer specifications, although each entity follows accepted practice, industry standards and, where appropriate, the Greenbook. A Standards of Practice (SOP, Appendix D) incorporating appropriate current sewer system design and construction standards and specifications was adopted by the City and District. The specifications included in this SOP would also apply to sewer pipeline rehabilitation and repair projects.

CITY OF UKIAN AND UKIAH VALLEY SANITATION DISTRICT August 2025 | 26

SANITARY SEWER MANAGEMENT PLAN

5.1.3 General Plan Design Flow Criteria
Standards of Practice design flows criteria were based, in part, on the City of Ukiah’s General Plan population and future development projections. The City’s General Plan was last adopted in 1995. The City has updated its Housing Element every five years since then, as required by State Law, with the most recent draft of the plan being published in 2022. As the City publishes its final version General Plan and future projections become known, design flow criteria should reflect these updates.

5.2 STANDARDS FOR INSPECTION AND TESTING OF NEW,

REHABILITATED AND REPAIRED FACILITIES

5.2.1 Regulatory Requirements for Inspection and Testing of New, Rehabilitated and Repaired Facilities Discussion
The “Standards for Inspection and Testing of New, Rehabilitated and Repaired Facilities” are a subsection of the Design and Performance Provisions Element of SSMP. The requirements are summarized as follows:
 The City and District must identify the procedures and standards for the inspection and testing of newly constructed, newly installed, repaired, and rehabilitated system pipelines, pumps, and other equipment and appurtenances.

5.2.2 Standards for Inspection and Testing of New, Rehabilitated and Repaired Facilities Discussion
Consistent with the philosophy that proper installation is the key element to ensure proper operation, the City and District have wastewater ordinances that mandate inspection and testing prior to acceptance of new or repaired facilities. This mandate is found in Section 3705.9 of the City’s ordinance and Section 6.9 of the District’s ordinance. The City and District ordinances are available online at www.codepublishing.com/CA/Ukiah/ and https://www.uvsd.org/ordinances, respectively.

In an effort to minimize infiltration, exfiltration, and better protect the environment, the City and the District initiated a private sewer lateral testing program in 2007, as codified by the City’s Wastewater Ordinance (Articles 1 and 18) and the District’s Wastewater Ordinance (Articles 5 and 9); both the City’s and District’s Sewer Lateral Ordinances were revised in January 2008. This program requires that all sewer laterals connected to the public sewer collection system be inspected and successfully pass a testing procedure upon the occurrence of qualified service calls, change of property use, building remodel or addition, sewer rehabilitation/repair, or spills.

These program requirements are detailed in Appendix D. A “qualified service call” is generally defined as a field response by the City to a problem identified in a portion of the sewer collection system. Notification for the qualified service call could come from inspection of the collection system (e.g., CCTV) or as evidenced by a spill that is reported to the City or District.

Prior to performing any sewer lateral testing, the property owner shall submit a completed application to the City or District (Appendix D). Once the application is approved and the permit

SANITARY SEWER MANAGEMENT PLAN
is issued, the property owner must contact a licensed contractor to perform the test. The following testing methods are acceptable:
 Closed Circuit Television (CCTV)
 Air Pressure Test
 Smoke Test
 Exfiltration Test
 Flow Monitoring
 Visual Inspection
 Other (as approved)
CCTV is typically the preferred method due to its viability and cost effectiveness. When the testing has been completed, the contractor performing the test submits a written report to the City or District presenting the test results and, in the case of CCTV testing, a copy of the video and inspection log. Upon receipt of the sewer lateral testing report and/or video, the City or District will execute a “Sewer Lateral Certification of Compliance” to the owner. Draft requirements and standards, permit application, and compliance certificate are found in Appendix D.

Often times, the need for lateral repair or replacement is an unanticipated event for a property owner. To help defray the cost of such replacement or repairing, the City and the District have established a Grant Program for eligible property owners. An application for this program is provided in Appendix C.
6 SPILL EMERGENCY RESPONSE PLAN
This section of the SSMP provides a summary of the City’s Spill Emergency Response Plan (SERP).

The complete plan is attached in Appendix F.

6.1 REGULATORY REQUIREMENTS FOR SPILL EMERGENCY RESPONSE PLAN
The regulatory requirements for the SERP element of the SSMP are summarized as follows:

The City shall develop and implement a Spill Emergency Response Plan that identifies measures to protect public health and the environment. The response plan should be developed as a stand-alone document and summarized in the SSMP. At a minimum, this plan must include procedures to:
a) Notify primary responders, appropriate local officials, and appropriate regulatory agencies of a spill in a timely manner;
b) Notify other potentially affected entities (for example, health agencies, water suppliers, etc.) of spills that potentially affect public health or reach waters of the State; c) Comply with the notification, monitoring and reporting requirements of the 2022 SSS WDR, State law and regulations, and applicable Regional Water Board Orders; d) Ensure that appropriate staff and contractors implement the SERP and are appropriately trained;

SANITARY SEWER MANAGEMENT PLAN
e) Address emergency system operations, traffic control and other necessary response activities;
f) Contain a spill and prevent/minimize discharge to waters of the State or any drainage conveyance system;
g) Minimize and remediate public health impacts and adverse impacts on beneficial uses of waters of the State;
h) Remove sewage from the drainage conveyance system;
i) Clean the spill area and drainage conveyance system in a manner that does not inadvertently impact beneficial uses in the receiving waters; j) Implement technologies, practices, equipment, and interagency coordination to expedite spill containment and recovery;
k) Implement pre-planned coordination and collaboration with storm drain agencies and other utility agencies/departments prior, during, and after a spill event; l) Conduct post-spill assessments of spill response activities; m) Document and report spill events as required in the 2022 SSS WDR; and n) Annually, review and assess effectiveness of the SERP, and update the Plan as needed.

6.2 SPILL EMERGENCY RESPONSE PLAN DISCUSSION
As previously noted, the City initially prepared its “Overflow Response and Notification Plan” in January 2002 and conducted various updates to meet evolving regulatory requirements. The complete SERP document is found in Appendix F and includes the following sections:

1. Authority

2. General

3. Spill Response Procedure

4. Public Advisory Procedure

5. Regulatory Agency Notification Plan

6. Media Notification Procedure

7. Distribution and Maintenance of SERP

6.2.1 Spill Notification, Response and Impact Mitigation Section 3 of the SERP explains spill response procedures from initial notification through field work and internal reporting and includes the following subsections:

A. Receipt of Information Regarding a Spill
This subsection describes the procedures and contact information for receiving a spill report from outside parties or the City personnel. A spill can be reported to City staff during regular business hours at a main phone number which is published in local phone books and on the City website (www.cityofukiah.com). The City also has an automated answering system to receive any calls during non-working hours, weekends, and holidays. A complete list of the internal officials who will receive an immediate spill notification and their contact information is represented in the SERP – Appendix B, “Spill Action Plan.” The role of each person during an emergency has been established in a flow chart and is clear and concise.

B. Dispatch of Appropriate Crews to Site of Spill

CITY OF UKIAN AND UKIAH VALLEY SANITATION DISTRICT August 2025 | 29

SANITARY SEWER MANAGEMENT PLAN
This subsection illustrates the protocols for immediately dispatching a crew to any site of a reported spill for investigation and response. The City’s SERP includes procedures for the notification of appropriate staff needed to respond to a spill in the event extra crews are needed or if the spill occurs outside normal City working hours. Guidelines for documenting any private or public property damages are explained and coordination with a hazardous material response team is also provided.

C. Spill Correction, Containment, Monitoring and Clean-Up In this subsection, specific actions to be performed by the crews during a spill are described. The City’s policy is to be constantly on alert and ready to take all steps possible to prevent the spill from reaching the storm drains, flood control channels, or waters of the State and/or United States, all in accordance with the City’s discharge requirements.

Upon arrival at a spill the City crew will initiate the following procedures:
 Determine the cause of the spill;
 Investigate the need for additional assistance or equipment;  Notify the dispatcher to call the Mendocino County Environmental Health Department, if private property is impacted;
 Take immediate actions to stop the spill.

The spill cleanup procedures for different situations, such as a trunk sewer stoppage, pump station failure, or wet weather spill, are detailed in Appendix B of the SERP. Under most circumstances, the City can handle all response actions with its own maintenance forces and equipment; however, circumstances may arise where the City would utilize its list of preapproved local vendors to acquire additional equipment. Local contractors would also be utilized for additional labor resources. A list of equipment vendors and contractors is provided in the SERP – Appendix B, Table 4.

This subsection also explains sampling laboratory tests requirements whenever a spill, regardless of volume spilled, reaches surface waters.

D. Overflow Report
The City has an Overflow Report form (SERP Appendix A) that must be completed for both internal and regulatory agency notification of spills. This subsection covers the information to be included in that form, such as date and location of the spill, start and stop time of the spill, estimate of the rate of the spill, indication whether the discharge reached water surfaces and cause of the spill. The Water/Sewer Maintenance Supervisor is responsible to complete the form and promptly forward it to Wastewater Treatment Plant Supervisor in order to notify the regulatory agencies when the spill is eliminated.

E. Customer Satisfaction
In this subsection, the City staff is required to follow up in person or by telephone with the parties reporting the spill and fill out a survey questionnaire. The survey is an assessment for response procedures, spill control and site clean-up, public notification and regulatory agency reporting. The survey is provided in SERP Appendix D.

SANITARY SEWER MANAGEMENT PLAN

6.2.2 Spill Public Notification
Section 4 of the SERP describes the actions the City takes to perform public advisory actions and limit public access to areas potentially affected by a spill. The Water/Sewer Maintenance Supervisor is responsible to determine whether temporary signage is required and, if so, the Mendocino County Environmental Health Department will be notified.

Media notification procedures are explained in Section 4 of the SERP. The Water/Sewer Maintenance Supervisor is responsible for notifying the Public Information Officer (PIO). The PIO is the “first-line” of response to the media for any spill.

6.2.3 Spill Regulatory Agency Reporting
Section 5 of the SERP establishes procedures that the City follows to provide formal notice to the regulatory agencies in the event of a spill. Criteria for reporting a spill to the Office of Emergency Services (Cal OES), the North Coast Regional Water Quality Control Board (RWQCB), Mendocino County Environmental Health Department and California Department of Fish and Game are specified depending on the size of the spill and whether or not the discharge affects surface water and/or results in fish kills. A complete list of the regulatory agencies and notification requirements is provided in SERP Appendix E.

The City submits a certification to the RWQCB that Cal OES and the Mendocino County Department of Environmental Health have been notified of any sewer discharge to a drainage channel or surface water. That certification is provided in SERP Appendix F.

6.2.4 Distribution and Maintenance SERP
Section 7 of the SERP provides guidelines for the distribution of the SERP, as well as an overview of the City procedures for ongoing review and updates to the SERP. Staff training is also discussed.
7 SEWER PIPE BLOCKAGE CONTROL PROGRAM
This section of the SSMP provides a description of the City’s Sewer Pipe Blockage Control Program for the wastewater collection system. Program elements include problem areas, legal authority, source controls, system maintenance, and public outreach.

7.1 REGULATORY REQUIREMENTS FOR SEWER PIPE BLOCKAGE

CONTROL PROGRAM
The regulatory requirements for the Sewer Pipe Blockage Control Program element of the SSMP are summarized as follows:

The City and District shall evaluate their service areas to determine whether a Sewer Pipe Blockage Control Program is needed. If it is determined that Sewer Pipe Blockage programs are not needed, justification must be provided. If pipe-blocking substances are found to be a problem, either the City, the District, or both must prepare and implement a Sewer Pipe Blockage control program to reduce the amount of these substances discharged to the sanitary

SANITARY SEWER MANAGEMENT PLAN
sewer system. The Sewer Pipe Blockage Control Program shall include the following as appropriate:
a) An implementation plan and schedule for a public education outreach program that promotes proper disposal of pipe-blocking substances;
b) A plan and schedule for the disposal of pipe-blocking substances generated within the sanitary sewer system service area. This may include a list of acceptable disposal facilities and/or additional facilities needed to adequately dispose of pipe-blocking substances generated within a sanitary sewer system service area;
c) The legal authority to prohibit discharges to the system and identify measures to prevent spills and blockages;
d) Requirements to install grease removal devices (such as traps or interceptors), design standards, maintenance requirements, BMPs requirements and record keeping and reporting requirements;
e) Authority to inspect grease producing facilities and enforce violations; f) A description of whether or not the City and the District have sufficient staff to inspect and enforce the FOG ordinance;
g) An identification of sewer system sections subject to FOG blockages and an established a cleaning maintenance schedule for each section; and
h) Implementation of source control measures, for all sources of FOG reaching the sanitary sewer system, for each sewer system section identified in (g) above.

7.2 SEWER PIPE BLOCKING CONTROL PROGRAM DISCUSSION
The City implements a FOG Control Program, discussed in detail below. The City does not have a formal root control or rag and debris program. O&M crews are aware of areas prone to roots and these areas are on the hot spots / sewer maintenance list (see discussion Section 4.2.2.1 and hot spots list in Appendix C). The City does not use chemicals for roots control. The City does not conduct any specific outreach regarding rags or wipes, aside from participation in the Russian River Watershed Association (see Section 7.2.5). Issues with rags and wipes blockages are generally in the laterals and result in backups into structures. Crews educate the homeowner/ business on the cause of the blockage at the time. The City used to conduct increased maintenance at one of its lift stations downstream from a senior home. It has since worked with the facility to install a screen at its connection to the public sewer. The facility regularly maintains the screen and no issues have been observed in the City infrastructure since its installation. This type of approach can be implemented at other facilities if similar issues are identified.

Fats, oils, and grease do not easily break down in a sewer collection system, especially when combined with other solid sewer waste constituents and subsurface obstructions (i.e., tree roots, offset joints, side sewer connections, etc.). As with highly-absorbent paper towels, wipes, rags and disposable diapers, FOG creates a maintenance problem that needs to be addressed on a constant basis. FOG can also increase operating costs at the Wastewater Treatment Plan WWTP) by causing high biological oxygen demand (BOD) and chemical oxygen demand (COD) levels.

CITY OF UKIAN AND UKIAH VALLEY SANITATION DISTRICT August 2025 | 32

SANITARY SEWER MANAGEMENT PLAN
A proactive approach to keeping the collection system free of blockages not only requires ongoing cleaning and maintenance, but also source identification, pretreatment and public education. The City has worked diligently to keep its and the District’s sewer system clear of obstructions. To aid in the process of refining its current regulatory, maintenance and outreach practices, the City has established a FOG Control Program that:
 Identifies FOG sources;
 Enforces City and District codes requiring the installation and maintenance of pretreatment facilities for non-domestic sanitary sewer customers;  Minimizes FOG related sewer blockages and spills in a cost-effective manner; and  Educates the public about FOG and its impact on the community and environment.

To refine its current practices and achieve these goals, the City has begun to modify its maintenance and operations procedures and documents. Using available resources from neighboring communities and its staff, the City has created tools including customer surveys, permit applications, and public information material. It has also enhanced its collection system inspection procedures and began to catalog known and potential FOG contributors.

Furthermore, the City continues to address all spills on the spot and takes corrective actions to prevent future occurrences by following the guidelines for investigating FOG-related spills provided in the City’s SERP which is found in Appendix F.

7.2.1 Legal Authority
Within their jurisdictional boundaries, both the City and the District have the legal authority to:
 Prohibit the discharge of fats, oils, and grease;
 Prohibit the discharge of pipe-blocking substances;
 Require the installation and maintenance of grease interceptors and traps; and  Enforcement of the Grease Ordinance, as appropriate.

UVSD’s Ordinance No. 1 was adopted in 1958 to regulate use of public sewers and drains. Article II Section 206 of Ordinance No. 1 details that any discharge of human or animal excrement, garbage, or other objectionable waste to the sewer is prohibited, and pipe-blocking substances fall into those categories. The City adopted Ordinance No. 845 Section 4, which prohibits objectionable waste as well, and the requirements of that ordinance were incorporated into City Code Article 3 in Chapter 2, Division 4. It prohibits the placement or deposit of human or animal excrement, garbage, or other objectionable waste on public or private property within City limits.

The City originally adopted Ordinance No. 1059 in 2004 to establish the authority to control the discharge of FOG to its sewer system. The requirements of that ordinance were incorporated into City Code Article 17.5 in Chapter 2, Division 4. The City’s Municipal Code, including Article 17, is available online at www.codepublishing.com/CA/Ukiah/ (updated as needed). The revised ordinance is discussed below. Additionally, in 2006, the District adopted Ordinance No. 28 that required all facilities that prepare, serve and make consumable food to install, use and maintain appropriate grease traps and/or inceptors.

CITY OF UKIAN AND UKIAH VALLEY SANITATION DISTRICT August 2025 | 33

SANITARY SEWER MANAGEMENT PLAN
In order to improve its FOG Control Program, the City adopted Ordinance No. 1111 in October 2008 as an amendment to Article 17 of Chapter 2, Division 4 of the City Code. Ordinance No. 1111 provides a new framework for the City’s FOG Control Program and a broad-reaching protection mechanism for the City of Ukiah’s POTW. The ordinance regulates the generation and disposal of grease interceptor waste and outlines general procedures for City compliance with SWRCB requirements and the City’s NPDES permit. As the City has grown, parcels from the District have been annexed into the City, but still remain under District jurisdiction. Ordinance No. 1111 supersedes the District’s Grease Interceptor Ordinance No. 28 for those properties that are located within the City’s boundary, but are still in the District.

All discussion in the following subsections on the City’s legal authority is based on the City’s Ordinance No. 845 and 1111 and District Ordinance No. 1 and 28 (Grease Ordinances), which are available online at www.codepublishing.com/CA/Ukiah/ and http://www.uvsd.org/ordinances, respectively.

7.2.1.1 Prohibition of Fats, Oils, and Grease Discharge The Grease Ordinances apply to all non-domestic users and prohibits the discharge of fats, oils and grease into the sewer system as follows:
“No User may intentionally or unintentionally allow the direct or indirect discharge of any petroleum oil, non-biodegradable cutting oil, mineral oil, or any Fats, Oils, or Greases of animals or vegetable origin into the POTW system in such amounts as to cause interference with the collection and treatment system, or as to cause pollutants to pass through the treatment works into environment.”
The City and District recognize that domestic (residential) users can also be a significant source of FOG, especially multi-family complexes. While the Grease Ordinances do not regulate the pretreatment of residential flows, portions of the sewer collection system impacted by residential FOG discharge will be targeted by other elements in the FOG Control Program, including identification and maintenance of problem areas and public outreach (Element 11).

7.2.1.2 Requirements for Installation and Maintenance of Grease Interceptor/Trap The Grease Ordinances require all non-domestic users (both existing and new users) to have an approved, adequately sized, and properly operated and maintained grease interceptor. For ongoing inspection and maintenance operations, as well as for health issues associated with exposure to impounded FOG, grease interceptors must be located outside of buildings in easilyaccessed locations. Where space limitations prevent adequate access for an exterior grease interceptor, the Director or District Manager may allow for the installation of a grease trap.

These devices are typically installed in the waste line leading from sinks, drains, and other fixtures inside the building.

The installation of any grease removal device is required to obtain a “Grease Interceptor Permit” from the City and District. To become permitted, all facilities must obtain a written interceptor service agreement with a licensed cleaning service and keep the interceptor in effective operating condition. All interceptors must be maintained at the owner’s expense and a maintenance record must be kept for a period of three years and be available for any inspection
