GLOSSARY

Site Cleanup
The Site Cleanup program addresses commercial, industrial and other non-military sites with non-fuel contamination. Many of these sites are considered Brownfields because of their reuse potential. Site Cleanup Requirements generally mandate a time schedule for specific tasks that must be performed by the responsible party(ies) to investigate and clean up the site. Water Board staff oversee implementation of these tasks including investigations, corrective actions, and human health risk assessments at sites with current or historic unauthorized discharges, which have adversely affected or threaten to adversely affect waters of the state.

Procedures for site investigation and remediation are promulgated in State Water Resources Control Board Resolution No. 92-49 entitled Policies and Procedures For Investigation and Cleanup and Abatement of Discharges Under Water Code Section 13304. Responsible parties conduct work in a stepwise fashion, starting with preliminary assessment, then soil and water investigation; interim remedial measures if warranted; risk assessment; setting cleanup goals; cleanup plan; cleanup implementation and monitoring. Most often, responsible parties conduct the work voluntarily, but sometimes enforcement orders are necessary to compel the work to be performed.

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.

Number of cleanup cases groundwater contaminant migration under contol
Means a count of all open Water Board-lead cases and Shared-lead cases where groundwater contaminant migration has been evaluated as of the end of the Fiscal Year.
