Section 87.155. Revegetation: standards for successful revegetation

(a) When the approved postmining land use is cropland, or as provided in subsection (c):

(1) The standards for successful revegetation shall be based upon crop productivity or yield.

(2) The approved standards shall be the average yields per acre for the crop and soil type as specified in the Soil Surveys of the United States Department of Agriculture Soil Conservation Service.

(3) The productivity or yield of the mined area shall be equal to or greater than the approved standard for the last two consecutive growing seasons of the 5-year responsibility period established in § 86.151 (relating to period of liability). Productivity or yield shall be considered equal if production or yield is at least 90% of the approved standard.

(b) When the approved postmining land use is other than cropland:

(1) The standards for successful revegetation shall be determined by ground cover.

(2) The approved standard shall be the percent ground cover of the vegetation which exists on the proposed area to be affected by surface mining activities. The Department will not approve less than a minimum of 70% ground cover of permanent plant species with not more than 1% of the area having less than 30% ground cover with no single or contiguous area having less than 30% ground cover exceeding 3,000 square feet. When woody species are planted in mixture with herbaceous species, the standards in this paragraph shall be met and a minimum of 400 woody plants per acre shall be established except:

(i) On slopes greater than 20 degrees, the minimum number of woody plants shall be 600 per acre.

(ii) When the approved postmining land use is commercial forest land, the minimum number of woody plants shall be 450 trees per acre with at least 75% commercial tree species.

(iii) When the approved postmining land use is wildlife habitat, the requirements of § 87.151(d) (relating to revegetation: species) shall apply and the areas approved for the planting of woody species shall have a stocking equal to or greater than 90% of the stocking of woody plants of the same life form on the proposed area to be affected by surface mining activities. The Department will not approve stocking of less than 400 woody plants per acre.

(3) The percent ground cover of the mined area shall meet the standards of paragraph (2) for a minimum of the last 2 consecutive years of the 5-year period of responsibility.

(4) For purposes of this section, ‘‘herbaceous species’’ means grasses, legumes, and nonleguminous forbs; ‘‘woody plants’’ means woody shrubs, trees and vines; and ‘‘ground cover’’ means the area of ground covered by the combined aerial parts of vegetation and the litter that is produced naturally onsite, expressed as a percentage of the total area of measurement.

(5) Trees and shrubs counted in determining revegetation success shall be healthy and have been in place for at least two growing seasons.

(c) When the approved postmining land use is pastureland, the crop productivity standards of subsection (a) and the ground cover standards of subsection (b) shall be met.
