Underground Storage Tanks (UST) Services

The California Department of Health Services and California State Water Resources Board teamed up to address public health and environmental issues linked to underground storage tanks containing fuel or hazardous substances. As a result, the agencies developed a series of procedures to determine if unauthorized releases have occurred. Unauthorized releases can cause contamination of soil and pose a threat to ground water, and can also directly affect ground water. Federal rules passed in 1988 required owners and operators to upgrade, close or replace their underground storage tank systems by December 22, 1998.
