Countywide Integrated Waste Management Plan

The California Integrated Waste Management Act directs counties to prepare a Countywide Integrated Waste Management Plan (CIWMP). This plan consists of a Source Reduction and Recycling Element (SRRE), a Household Hazardous Waste Elements (HHWE), and a Nondisposal Facility Element (NDFE) of each jurisdiction, the Countywide Siting Element, and the Countywide Integrated Waste Management Summary Plan. The CIWMP addresses waste management conditions and provides an overview of the actions that will be taken to achieve the diversion requirements of Public Resources Code section 41780 and to maintain 15 years of disposal capacity.

California statute requires the County of San Mateo to review its CIWMP every five years and then report on its adequacy to the California Integrated Waste Management Board (CIWMB). The last review of the CIWMP was completed in 2024.

Depending on the results of the review, a revision to the CIWMP may be required; however, minor updates to its elements may also be completed annually through the Electronic Annual Report.
