CERS Quality Assurance Review
The State Water Resources Control Board’s (State Water Board) goal in providing this guidance is to assist the CUPA in performing their own CERS data review. Below are the specific quality assurance items from the CERS UST Facility Tank/ Data Download Report reviewed by staff during the CUPA evaluation. Staff may review all or part of the listings during the evaluation. CUPAs should perform a review of their data on an annual basis.
Note: State Water Board evaluation staff will provide training to CUPA staff upon request. CUPAs may contact staff for assistance with the review process.
The following items are evaluated on the UST Tank & Monitoring Plan Info tab of the CERS UST Facility Tank/Data Download report using the filter feature:
