To guarantee restoration, rehabilitation, and reclamation of mined-out areas, every applicant granted a mining permit as herein provided shall furnish a surety bond to the town in the amount of not less than five thousand dollars ($5,000.00), the upper limit to be determined by the town council, as a guarantee that such applicant, in restoring, reclaiming, and rehabilitating such land, shall, within a reasonable time and to the satisfaction of the town council, meet the following requirements:
(1) Grading; prevention of standing water.
All excavation shall be made either to water producing depth, such depth to be not less than five feet (5') below the low-water mark, or shall be graded or backfilled with non-noxious, nonflammable and noncombustible solids, to secure that the excavated area shall not collect and permit to remain therein stagnant water or that the surface of such area which is not permanently submerged is graded or backfilled as necessary so as to reduce the peaks and depressions, so as to produce a gently running surface that will minimize erosion due to rainfall and which will be in substantial conformity to the adjoining land area.
(2) Vegetation.
Vegetation shall be restored by appropriate seeds, grasses, or planting of shrubs or trees in all parts of said mining area where such area is not to be submerged under water as hereinabove provided.
(3) Banks of excavations.
The banks of all excavations not backfilled shall be sloped to the water line at a slope which shall not be less than three feet (3') horizontal to one foot (1') vertical, and said bank shall be seeded.
(4) Additional requirements.
In addition to the foregoing, the town council may impose such other conditions, requirements, or limitations concerning the nature, extent of the use, and operation of such mines, quarries, or gravel pits as the town council may deem necessary for the protection of adjacent properties and the public interest. The conditions and the amount of the surety bond shall be determined by the town council prior to the issuance of the permit.
