Draft tightens testing, reporting and closure rules; cleanup agencies hold primary corrective-action authority

Staff described significant changes in inspection, testing, reporting and corrective-action procedures intended to speed detection and remediation of releases and to clarify which agencies carry enforcement authority. Among the changes: reserve (release-detection) test results must be submitted within 30 days (down from 60), and the draft updates the release-reporting sequence so owners must provide an initial written report that includes facility ID and address. UPAs are required to transmit initial written report information to the cleanup oversight agency (COA) within 60 days to enable faster scope-setting for remediation.

The draft also contains a new alternate inspection requirement when release-detection equipment is out of service more than 24 hours: a physical inspection of primary and secondary containment at 24-hour intervals is required, and a longer-term disablement (30 days or more) triggers permanent closure obligations unless appropriate mitigation is approved. Staff said mechanical release-detection devices have often failed testing and the draft favors replacement with continuous electronic detection in some settings.

For closure, staff said temporary closure requires UPA approval and that permanent closure activities (including soil and groundwater sampling) should be completed within 365 days; owners must submit a permanent-closure report to the UPA within 30 days containing site maps, sample depths and lab reports. In enforcement, the draft assigns monitoring and corrective-action authority to cleanup oversight agencies, not UPAs, and requires feasibility studies that evaluate cost and environmental footprint when selecting remedial approaches.

Staff presented the changes for Board review; no formal vote or final Board action was recorded during the presentation.
