(a) The operator of a horizontal well shall reclaim the land surface within the area disturbed in siting, drilling, completing or producing the well in accordance with the following requirements:
(1) Except as provided elsewhere in this article, within six months after a horizontal well is drilled and completed on a well pad designed for a single horizontal well, the operator shall fill all the pits and impoundments that are not required or allowed by state or federal law or rule or agreement between the operator and the surface owner that allows the impoundment to remain open for the use and benefit of the surface owner (i.e. a farm pond as described in section nine of this article) and remove all concrete bases, drilling supplies and drilling equipment: Provided, That impoundments or pits for which certificates have been approved pursuant to section nine of this article shall be reclaimed at a time and in a manner as provided in the applicable certificate and said section. Within that six-month period, the operator shall grade or terrace and plant, seed or sod the area disturbed that is not required in production of the horizontal well in accordance with the erosion and sediment control plan. No pit may be used for the ultimate disposal of salt water. Salt water and oil shall be periodically drained or removed and properly disposed of from any pit that is retained so the pit is kept reasonably free of salt water and oil. Pits may not be left open permanently.
