-
(A) A person to whom a permit to plug a well has been issued shall not pull conductor casing or drive pipe from the wellbore.
(B) A person has to attempt to pull un-cemented surface casing from a well prior to emplacing approved plugging material to protect underground sources of drinking water or a mineable coal seam. Prior to pulling un-cemented surface casing from a well, the person has to bail or circulate the wellbore using fresh water in a manner that removes all free crude oil and brine from inside the wellbore.
(C) When a well does not have drive pipe, conductor casing, or surface casing, the plugging plan required under paragraph (E) of rule 1501:9-11-02 of the Administrative Code has to protect all USDWs and provide a means of well control for completion of plugging operations. Any casing installed in the well has to be according to the standards established in rule 1501:9-1-08 of the Administrative Code.
