Underground Storage Tanks
The Groundwater Protection Act (Sher, 1983) created the Underground Storage Tank (UST) program in California. The State Water Board maintains statewide authority over the program, adopting cleanup policies and regulations. The two main components of the program are permitting of operating tanks (leak prevention) which is run by the local Certified Unified Program Agencies (CUPAs), and cleanup which is shared between select CUPAs and the 9 Regional Water Quality Control Boards. Authority to require UST cleanups is found in both the Water Code and the Health and Safety Code.
GeoTracker is a database and geographic information system (GIS) that provides online access to environmental data. It tracks regulatory data about underground fuel tanks and public drinking water wells, as well as other types of sites, such as above ground storage tanks and site cleanup cases.
Water Purveyor MtBE Quarterly Report
Water Purveyor MtBE Quarterly Report for Central Valley Sites, current as of April 2019 California Water Code Section 13272.1 requires Regional Water Quality Control Boards to publish and distribute, on a quarterly basis, a list of dischargers of Methyl Tertiary Butyl Ether (MtBE). We have revised our format to provide better information and ease of use. We modified the MtBE report to show concentrations less than 5 ppb, the secondary MCL.
Leaking Underground Storage Tanks (LUST)
A list of Leaking Underground Storage Tanks (LUST) cases in the Central Valley Region can be found on the Geotracker website at: http://geotracker.waterboards.ca.gov/
By selecting one of the links under the "Reports" section on the left side of the screen, a list of LUST cases can be generated based on County, Groundwater sub-basin, or Regional Board Watershed.
