(ii) Plans for restoration of the site, including provisions for proper cover to prevent excessive runoff and erosion; and

(iii) Narrative description of methods for proper closure of all permitted nonhazardous impoundments.

(D) The approved plugging and abandonment plan shall be implemented and completed within six (6) months, unless otherwise specified by the DEQ.

(E) The operator shall notify the DEQ of the exact time when plugging operations will take place.

(F) Within thirty (30) days after a well has been plugged, the owner or operator shall file a plugging record with the DEQ.
