FINANCIAL IMPACT
Approval of this item will not result in the use of Discretionary General Funding (Net County Cost) as adopting the Sewer System Management Plans (SSMP) updates are non-financial in nature. Sufficient appropriations were included in the Department of Airports (Airports) and County Service Area 70 - Countywide’s (CSA 70) 2025-26 respective budgets. The cost for the preparation of the SSMP updates will be paid by CSA 70, and reimbursed by Airports under terms of the Memorandum of Understanding (MOU) between San Bernardino County (County) on behalf of Airports and CSA 70, Agreement No. 22-145, that was approved by the Board of Supervisors (Board) for the County and on behalf of CSA 70 on March 1, 2022 (Item No. 70). This MOU provides for the preventative maintenance, emergency response, and support service for the wastewater collection system and water distribution system at Chino Airport through February 28, 2027.
BACKGROUND INFORMATION
CSA 70 provides operation, maintenance and management to the wastewater collections systems at Chino Airport in a manner consistent with the requirements of all Federal and State regulatory agencies. This item seeks approval to adopt updated Sewer System Management Plans for Chino Airport in compliance with State Water Resources Control Board (SWRCB) requirements. A SSMP is a regulatory document that establishes the policies, procedures, and activities needed to operate, maintain, and improve the sewer system, reduce the risk of spills and overflows, and ensure compliance with regulatory requirements.
The Sanitary Sewer Systems General Order requires agencies to conduct an internal audit of their SSMPs every three years and an update every six years. On December 6, 2022, the SWRCB adopted the reissued Sanitary Sewer Systems General Order with the effective date of June 5, 2023. This included an extension to submit audits and updates due to additional criteria in the General Order. Therefore, the existing SSMP, which was originally effective through March 26, 2027, will need to be updated by August 2, 2026. Approval of this item will update the SSMPs to be compliant with SWRCB Order No. 2022-0103-DWQ and Order No. WQ 2013-0058-EXEC regulating statewide general waste discharge requirements for sanitary sewer systems within the new timeframes.
To provide a consistent, statewide regulatory approach to address sanitary sewer spills and sanitary sewer overflow, SWRCB adopted Statewide General Waste Discharge Requirements for Sanitary Sewer Systems, Water Quality Order No. 2022-0103-DWQ (Sanitary Sewer Systems General Order) on December 6, 2022 and Order No. WQ 2013-0058-EXEC (Statewide Waste Discharge Requirements for Sanitary Sewer System) on September 9, 2013.
The Sanitary Sewer Systems General Order requires public agencies that own or operate sanitary sewer systems to develop and implement SSMPs and report all sanitary sewer spills to the SWRCB’s online California Integrated Water Quality System Sanitary Sewer System, Database. As part of its duties, CSA 70 is responsible for the establishment of a SSMP for the wastewater collection system at Chino Airport, which is greater than one mile in length, to meet the SWRCB requirements.
The objective of the SSMP is to provide a plan and schedule to properly manage, operate and maintain all parts of the sanitary sewer system at Chino Airport. The SSMP is established to be consistent with the following goals:
• Maintain or improve the condition of the sewer collection system infrastructure to provide reliable service now and in the future;
• Mitigate infiltration and inflow to adequately provide for sewer capacity and accommodate design storm flow; and
• Minimize the number and impact of any sanitary sewer overflows that may occur.
The updated SSMPs for Chino Airport which include updated organizational information, recent spill reporting, and audit-related updates, will help meet these goals.
On March 29, 2022 (Item No. 44), the Board adopted the SSMPs for the wastewater collection systems located in Chino Airport.
