Announcements

OWNERS/OPERATORS OF SINGLE-WALLED USTS

The deadline for removal of all single-walled USTs is December 31, 2025. Loans and grants are available through the RUST program to assist eligible small businesses to remove single-walled USTs and to replace them with double-walled USTs. If you are eligible for RUST funding, you cannot begin work until you have a grant or loan executed by the State Water Board. Upon UST removal, if a release has occurred, owners/operators may need to undertake corrective action (i.e., investigate and clean up the release). Filing a claim application with the UST Cleanup Fund, completing corrective action, and receiving reimbursement for eligible corrective action costs is a lengthy process. The deadline for submittal of a claim application to the UST Cleanup Fund for reimbursement of eligible costs for corrective action is December 31, 2024. The UST Cleanup Fund sunsets on January 1, 2026. Do not delay.

Information on eligibility requirements for reimbursement for corrective action by the UST Cleanup Fund can be found at https://www.waterboards.ca.gov/water_issues/programs/ustcf/.
