RECOMMENDATION(S):

APPROVE and AUTHORIZE the Chief Engineer, Contra Costa County Flood Control and Water Conservation District, or designee, to execute, on behalf of the Contra Costa Clean Water Program, a contract amendment with Larry Walker Associates, Incorporated, effective October 5, 2021, to increase the payment limit by $615,000 to a new payment limit of $915,000 for Countywide stormwater quality services necessary to comply with federal and state stormwater permit requirements issued under the National Pollutant Discharge Elimination System Permit, with no change to the term of January 5, 2021 through December 31, 2023, Countywide. (100% Stormwater Utility Assessment Funds)

FISCAL IMPACT:

All costs associated with this contract will not exceed $915,000 and will be funded 100% by Stormwater Utility Assessment fees collected by the Cities/Towns and County, proportional to their respective populations.








BACKGROUND:

The Contra Costa Clean Water Program (the “CCCWP”) consists of Contra Costa County, its 19 incorporated cities/towns and the Contra Costa County Flood Control and Water Conservation District (hereinafter referred to collectively as “Permittees”). The CCCWP was established in 1991 through a Program Agreement in response to the 1987 amendments to the federal Clean Water Act (the “CWA”), which established a framework for regulating municipal stormwater discharges under the National Pollutant Discharge Elimination System (“NPDES”) Permit Program. The United States Environmental Protection Agency (the “USEPA”) published final rules implementing the 1987 CWA amendments in November 1990.  
  
The rules mandate that Permittees obtain and implement stormwater permits designed to reduce and eliminate the discharge of pollutants into and from Municipal Separate Storm Sewer Systems (the “MS4s”) they own and operate. Through the CCCWP, Permittees conduct many of the mandated activities collectively (referred to as “Group Activities”), such as water quality monitoring, special studies, and public education. The roles and responsibilities of the CCCWP and Permittees are outlined in the Contra Costa Clean Water Program Agreement, which was last updated and adopted by all Permittees in June 2010. The current San Francisco Bay Region Municipal Regional Stormwater NPDES Permit No. CAS612008, Order R2-2015-0049 (“Permit”), was issued in November of 2015.  
  
The CCCWP Permittees request to retain Larry Walker Associates, Incorporated, to plan, coordinate and administer mandated stormwater quality management activities as required by the NPDES permit. Larry Walker Associates, Incorporated, will assist the Program by negotiating permit requirements, attending various stakeholder meetings on behalf of Permittees, preparing written responses to the Regional Water Quality Control Boards and will complete other activities related to the re-issuance and implementation of the NPDES permit.

CONSEQUENCE OF NEGATIVE ACTION:

Without the approval of the Board of Supervisors, the CCCWP, 19 Cities and Towns, Contra Costa County, and the Flood Control District will be unable to meet the outreach requirements set forth by the San Francisco Bay Region Municipal Regional Stormwater NPDES Permit No. CAS612008, Order R2-2015-0049.
