* There is no statewide requirement for a specific laboratory test. Contact the lead agency for guidance. Note: Soil and water analyses must be conducted by a California Department of Health Services (DHS) accredited laboratory. Contact California DHS Environmental Laboratory Accreditation Program (ELAP) at (510-540-2800)

** Notification is required for all unauthorized releases unless the operator is able to clean up the release within 8 hours, the release did not escape from a secondary containment, or from primary containment if no secondary containment exists, does not increase hazard of fire or explosion and did not deteriorate secondary containment of UST.

*** If BTEX levels are detectable, even though TPH concentration is below 10mg/L (gasoline) or 100mg/L (diesel), proceed from site investigation to the general risk appraisal.

Note: California does not have statewide standard cleanup levels. Values shown are recommended action levels from the LUFT Field Manual. Cleanup levels are site specific and may be applied differently from region to region. California has 9 Regional Water Quality Control Boards and 104 local agencies throughout the state. The Regional Water Quality Control Board is generally the lead on complex unauthorized UST releases, groundwater cases and cases referred to them by the local agency.  Larger implementing local agencies with staff, expertise, and Regional Water Quality Control Board concurrence may be the lead in overseeing corrective action to these cases. The jurisdiction or Regional Water Quality Control Board enforces site specific cleanup levels, detection levels, etc. Contact information for the 9 Regional Water Quality Controls Boards can be found on the SWRCB website.
