Underground Storage Tanks

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.

Additional Information

  The California Leaking Underground Fuel Tank Guidance Manual (Manual) is intended to assist stakeholders involved in the California State Water Resources Control Board Underground Storage Tank (UST) Cleanup Program to meet the Program’s main objective of protecting human health, safety, and the environment from petroleum products and/or petroleum additives which have leaked from USTs and/or their associated systems. The Manual provides guidance to stakeholders and to assist them in making informed decisions regarding the investigation and cleanup of unauthorized releases of fuels from USTs in the State of California.
