Underground Storage Tank (UST) Program

Leak Prevention

The State Water Board established regulations governing prevention of leaks from underground storage tanks (USTs). There are published standards and requirements for installation, tank construction, tank testing, leak detection, spill containment and overfill protection. California UST laws and regulations give local agencies (counties, cities, or other local agencies) authority throughout the State to issue permits for tank operation and to enforce tank testing requirements within their jurisdiction.
