2023 Oklahoma Statutes › Title 45. Mines and Mining › §45-725. Procedure for reclaiming land.

A. All affected land other than lands affected by coal mining operations shall be reclaimed as provided in this section.
B. The operator shall determine which parts of the affected land shall be reclaimed for forest, pasture, crop, horticultural, homesite, recreational, industrial or other use including food, shelter and ground cover for wildlife.
C. All ridges and peaks of overburden created by surface mining shall be graded to a rolling topography traversable by machines or equipment customarily used in connection with the use to be made of the land after reclamation, but such slopes need not be reduced to less than the original grade of the area prior to mining, and the slope of the ridge of overburden resulting from a box cut need not be reduced to less than twenty-five degrees (25°) from horizontal. Surface mining operations conducted in the flood plains of streams and rivers and subject to periodic flooding shall be exempt from the grading requirements of this section.
D. The operator may construct earth dams to form lakes in pits resulting from surface mining operations, provided that the formation of lakes shall not interfere with other mining operations or damage property of others.
E. The operator shall cover the exposed face of a mineral seam, where significant concentrations of acid-forming materials are present, to a depth of not less than three (3) feet with earth that will support plant life or with a permanent water impoundment.
F. The operator shall grade down the banks of any pits or depressions created by the removal of sand or gravel by surface mining to a degree of slope determined by the Department, which shall give due consideration to the natural topography of the land affected and adjacent lands, the composition of such banks and the most beneficial use of the pits and depressions comprising the affected land after reclamation. If the pits or depressions are deeper than ten (10) feet, the operator may elect to bench the highwall, provided that such benches are not in excess of ten (10) feet in height.
G. All affected land except that which is to be covered with water or used for homesites or industrial purposes shall be revegetated by the planting of seeds, plants, trees, shrubs or other plantings appropriate to the use to be made of the land as determined by the operator. No planting of any kind shall be required on any affected land so long as the chemical and physical characteristics of the soil of such affected land are toxic, deficient in plant nutrients or composed of sand, gravel, shale or stone to such an extent as to seriously inhibit plant growth. The Department may prescribe by rules and regulations the required density of such plantings, and may make replanting requirements.
H. Except where prevented by weather conditions, all grading shall be completed within one (1) year after mining of the affected land has been completed. Initial seeding or planting shall be made at the first appropriate time following completion of grading. If the operator is unable to acquire sufficient planting stock of desired species from state nurseries, or acquire such species elsewhere at comparable prices the Department shall grant the operator an extension of time until planting stock is available to plant such land as originally planned.
I. In any noncoal mining operation where the type and amount of material removed precludes the filling of the quarry, the Department of Mines shall prescribe necessary measures for the protection of the public and animal life.
