DEQ is not reopening HOT sites that were closed according to the rules and regulations at the time of the assessment and certification. If site conditions at your property have not changed, DEQ will not require you or the licensed DEQ service provider who did the work to do additional work.
DEQ may require additional work if the site was/is redeveloped or new information indicates that the original assessment did not adequately characterize site conditions.
If you’re concerned with the potential risk associated with remaining contamination on your property, first, review the original file and lab results to see if potential risk exists; if so, you may want to consider conducting additional assessment. Additional assessment may include soil, gas or indoor air sampling to assess current site conditions.
