§ 88-11.820. Drainage, erosion and sediment control.

(a)

Any temporary stream or watershed diversion shall be restored in final reclamation to its condition prior to surface mining operations, unless the planning agency determines restoration is unnecessary.

(b)

Regrading and revegetation shall be designed and carried out to minimize erosion, to provide for drainage to natural outlets or interior basins designed for water storage, and to eliminate closed depressions and similar catchments that could serve as breeding areas for insects.

(c)

Silt basins, which have outlet to lower ground and will or may store water during periods of surface runoff, shall be equipped with sediment control and removal facilities, and with protected spillways designed to minimize erosion.

(d)

Final grading and drainage shall be designed to prevent discharge of sediment loads higher than before mining operations.

(e)

Upon reclamation, the operator shall preclude or eliminate any condition which will or could lead to the degradation of water quality below applicable standards of the regional water quality control board or any other agency with authority over water quality.

(Ord. 79-114).
