(A) Prior to the commencement of drilling operations, the drill site shall be enclosed on all sides by a fence of solid wood or equivalent, not less than eight feet in height except for those sides on which there exists a natural or artificial barrier of equal or greater solidity and height. Solid wood board gates shall be installed in the fencing and shall be equipped with keyed locks. The gates shall be kept locked at all times when the drill site is unattended. Any and all supporting members of the fence shall be on the interior of such fence. The fence or wall shall be in lieu of any other fencing requirements.
(B) If by reason of location it is impractical to provide such fencing, the Agency may grant an exception to the requirements of this section; provided the Agency first finds that compliance with such fencing requirement is impractical or unnecessary and that the integrity of the neighborhood or area will not be adversely affected if such exception is granted.
