Current through Register Vol. 51, No. 21, October 18, 2024

Section 26.20.29.05 - Soil-Stabilizing Practices

A. Suitable mulch and other soil-stabilizing practices shall be used on all regraded and topsoiled areas to control erosion, promote germination of seeds, or increase the moisture-retention capacity of the soil. The Bureau may modify this if seasonal, soil, or slope factors result in a condition when a lower application rate of mulch is adequate to control erosion and to promptly establish an effective vegetative cover.

B. When required by the Bureau, mulches shall be mechanically or chemically anchored to the soil surface to assure effective protection of the soil and vegetation.

C. Annual grasses and grains may be used alone, as in situ mulch, or in conjunction with another mulch, when the Bureau determines that they will provide adequate soil erosion control and will later be replaced by perennial species approved for the postmining land use.

D. Chemical soil stabilizers, alone or in combination with appropriate mulches, may be used in conjunction with vegetative covers approved for the postmining land use.

E. The minimum rate of application for hay or straw mulch is 2-----3 tons per acre.

F. Other mulching materials may be substituted for hay or straw, on written request from the operator, and approval of the Bureau, of the mulch material and the rate of application.
