Announcements
Owners / Operators of Single-Walled USTs
IMPORTANT INFORMATION: Single-walled underground storage tanks (USTs) must be permanently closed by December 31, 2025. This requirement includes both single-walled tanks and nonexempt single-walled piping per California Health and Safety Code, chapter 6.7, section 25292.05. Single-walled UST systems that are not permanently closed by December 31, 2025 will be out of compliance and cannot be operated. Owners and/or operators will be subject to enforcement actions, including affixing red tags and pursuing civil penalties beginning January 1, 2026. For more information, please review the Single Walled webpage.
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, 2034. The UST Cleanup Fund sunsets on January 1, 2036. Do not delay.
View information on eligibility requirements for reimbursement for corrective action by the UST Cleanup Fund.
