SB 454: State Water Resources Control Board: PFAS Mitigation Program.

Official summary

Legislative Counsel’s Digest (official, as of the latest version). Written by nonpartisan legislative staff; reproduced verbatim.

Existing law designates the State Water Resources Control Board as the agency responsible for administering specific programs related to drinking water, including, among others, the California Safe Drinking Water Act and the Emerging Contaminants for Small or Disadvantaged Communities Funding Program.

This bill, which would become operative upon an appropriation by the Legislature, would enact a perfluoroalkyl and polyfluoroalkyl substances (PFAS) mitigation program. As part of that program, the bill would create the PFAS Mitigation Fund in the State Treasury and would authorize certain moneys in the fund to be expended by the state board, upon appropriation by the Legislature, for specified purposes. The bill would authorize the state board to seek out nonstate, federal, and private funds designated for PFAS remediation and treatment and deposit the funds into the PFAS Mitigation Fund. The bill would continuously appropriate these funds to the state board for specified purposes. The bill would authorize the state board to establish accounts within the PFAS Mitigation Fund. The bill would authorize the state board to expend moneys from the fund in the form of a grant, loan, or contract, or to provide assistance services to water suppliers and sewer system providers, as those terms are defined, for multiple purposes, including, among other things, to cover or reduce the costs for water suppliers associated with treating drinking water to meet the applicable state and federal maximum PFAS contaminant levels. The bill would require a water supplier or sewer system provider to include a clear and definite purpose for how the funds will be used to provide public benefits to their community related to safe drinking water, recycled water, stormwater, or treated wastewater in order to be eligible to receive funds. The bill would require the state board to adopt guidelines to implement these provisions, as provided.
