WHAT THE MEASURE IS SHOWING

On May 1, 2012, the State Water Board adopted a Low-Threat Underground Storage Tank Case Closure Policy to improve UST cleanup process efficiency. A benefit of improved efficiency is the preservation of limited resources for mitigation of releases posing a greater threat to human and environmental health.

 

WHY THIS MEASURE IS IMPORTANT

GLOSSARY

Leaking Underground Storage Tanks
Leaking underground storage tanks are a significant source of petroleum impacts to groundwater and a risk to human health and safety. Contamination may impact drinking water aquifers, public or private drinking water wells, and present a risk of exposure to humans through inhalation of vapors. These threats are minimized when UST owners or operators (responsible parties) report a leak to the environment to the local regulatory agency within 24 hours of detection. If a leak occurs, responsible parties or their representative must notify the appropriate Regional Water Quality Control Board or County Agency and submit an unauthorized release form. Site investigation and cleanup (corrective action) costs can only be reimbursed by the Cleanup Fund after the tank release has been reported to the Regional Board or county regulatory agency. Regional Board and many County Agencies are authorized to oversee the investigation and cleanup of UST system releases.

Case Closure
UST site qualifies to receive a "No Further Action" (closure) letter once the owner or operator meets all appropriate corrective action requirements. After this occurs, the county agency or regional board will inform the responsible party in writing that no further work is required.

Low-Threat Underground Storage Tank Case Closure Policy
This policy is a state policy for water quality control and applies to all petroleum UST sites subject to Chapter 6.7 of Division 20 of the Health and Safety Code and Chapter 16 of Division 3 of Title 23 of the California Code of Regulations.
