UST Program Overview
The Ventura County Environmental Health Division regulates the installation, operation, repair, and closure of Underground Storage Tank (UST) systems within Ventura County, with the exception of the City of Oxnard and the City of Ventura.
The goal of the UST Program is to protect public health and safety, the environment, and groundwater from releases of petroleum and other hazardous substances. This is accomplished through plan check and inspection activities that ensure UST facilities are properly permitted and meet the release detection and monitoring requirements applicable to their type of equipment. Each UST system is inspected annually to determine compliance with all applicable laws, regulations, and local ordinances.

Closure of Single-Walled USTs (SB445)
On September 25, 2014, the Governor signed Senate Bill (SB) 445 requiring the removal of all single-walled USTs in California with a deadline of December 31, 2025. Loans and grants are available through the RUST program to assist eligible small businesses in removing single-walled USTs and replace them with double-walled USTs which meet current standards.

Reporting Unauthorized Releases
Unauthorized Release: When is Reporting Required?
An unauthorized release that escapes from the secondary containment, or from the primary containment, if no secondary containment exists, increases the hazard of fire or explosion, or causes deterioration of the secondary containment of the underground tank system shall be reported by the owner or operator to the local agency within 24 hours.
Unauthorized Release: When is Only Recording Sufficient?
Any unauthorized release from the primary containment (into the secondary containment) which the operator is able to clean up within eight hours after the release was detected or should reasonably have been detected, and which does not escape from the secondary containment, does not increase the hazard of fire or explosion, and does not cause any deterioration of the secondary containment of the underground storage tank, shall be recorded on the operator’s monitoring reports.
