Sec. 12. "Approximate original contour" means that surface configuration achieved by backfilling and grading of the mined area so that
the reclaimed area, including any terracing or access roads, closely resembles the general surface configuration of the land prior to mining and blends

water impoundments may be permitted where the director has determined that they comply with the performance standards of this article.
