No oil or gas well owner or agent of an oil or gas well owner shall fail to restore the land surface within the area disturbed in siting, drilling, completing, and producing the well as required in this section.
The owner shall be released from responsibility to perform any or all restoration requirements of this section on any part or all of the area disturbed upon the filing of a request for a waiver with and obtaining the written approval of the chief, which request shall be signed by the surface owner to certify the approval of the surface owner of the release sought. The chief shall approve the request unless the chief finds upon inspection that the waiver would be likely to result in substantial damage to adjoining property, substantial contamination of surface or underground water, or substantial erosion or sedimentation.
The chief, by order, may shorten the time periods provided for under division (A) or (B) of this section if failure to shorten the periods would be likely to result in damage to public health or the waters or natural resources of the state.
The chief, upon written application by an owner or an owner's agent showing reasonable cause, may extend the period within which restoration shall be completed under divisions (A) and (B) of this section, but not to exceed a further six-month period, except under extraordinarily adverse weather conditions or when essential equipment, fuel, or labor is unavailable to the owner or the owner's agent.
If the chief refuses to approve a request for waiver or extension, the chief shall do so by order.
