Final restoration - Restoration values achieved

The operator shall notify the department if the results of six consecutive sample sets taken once every two months show that ground water quality in the production zone meets the restoration values on the restoration table and that the restoration values indicate stable trends. After the department in writing confirms ground water restoration, the operator may request, through a technical revision, that the department modify the site water quality monitoring plan, which may include a reduction in sampling frequency, substances to be measured, and the number of wells to be sampled in the restored production zone.
