Report Title: On-call Contract Amendment with Blankinship & Associates, Inc., Countywide.
☒Recommendation of the County Administrator ☐ Recommendation of Board Committee

RECOMMENDATIONS:
APPROVE and AUTHORIZE the Public Works Director, or designee, to execute a contract amendment with Blankinship & Associates, Inc., to extend the term through March 31, 2025, for on-call professional stormwater quality services for a variety of National Pollutant Discharge Elimination System (NPDES) Permit requirements, with no change to the payment limit, Countywide.
FISCAL IMPACT:
There is no fiscal impact with this action, as it is only to extend the term of the contract. This project, including the contract, will be funded 80% by the agencies under the Aquatic Pesticides NPDES Permit Joint Exercise of Powers Agreement (JEPA), including Contra Costa County Flood Control and Water Conservation District (FC District), and 20% by the Stormwater Utility Area Assessment Funds. Project No. 7517-6W7241
BACKGROUND:
The Contra Costa County Watershed Program (CWP) is responsible for implementing the San Francisco Bay Regional Water Quality Control Board Municipal Stormwater Permit (MRP) under the NPDES No. CAS612008 on behalf of Contra Costa County, including Contra Costa County Public Works and the FC District. The FC District is one agency under the JEPA for the Aquatic Pesticide Permit. The other JEPA members include the City of Antioch, Alameda County Public Works, and Zone 7 Water Agency. The City of Concord was active when the group was formed in the early 2000s, but has been inactive with the JEPA and NPDES for over a decade. The JEPA was formed to develop and implement a monitoring plan for each discharger’s permit under the Aquatic Pesticide (Water Quality Order No. 2013-0002-DWQ, General Permit No. CAG990005) general NPDES Permit.
The NPDES MRP requires municipalities to reduce pollutants in the stormwater flowing through their drainage systems and waterway, subsequently reducing negative impacts to receiving waters from trash, abandoned waste, and other pollutants of concern found in urban runoff.
The CWP requires on-call professional service contracts for the provision of expertise in a variety of technical fields in support of meeting requirements of the NPDES Permits and additional County initiatives.
CONSEQUENCE OF NEGATIVE ACTION:
Without the approval of this contract by the Board of Supervisors, Contra Costa County will be unable to meet its requirements under the amended MRP No. CAS612008 and General Permit No. CAG990005.
