Section 780.18 (b) Continued. Revised 11/20/80 Mixture. Stockpiles will be broadcast seeded at the rate of ap- proximately 80 pounds per acre for annuals and 30 pounds per acre for perennials with planting to occur in either the spring or the fall. The perennial grass seed component of the Kerr Mine Area seed mixture will be seeded at the same time the annuals are seeded. In addition to the planted material, a considerable amount of volunteer growth can be expected to grow on ali stockpiled topsoil. In the event the above-described erosion control measures prove unsuccessful on any specific stockpile, straw mulch will be applied using a mulch blower at the rate of 3,000 pounds per acre. The criteria that will be used to determine failure to establish annual grains will be the appearance of active wind or water erosional feat~These will be visible signs of down cutting and erosion- al fanning at the base of the stockpiles. However, since the past experience of Kerr Coal indicates that annual grains are highly i effective in stabilizing topsoil stockpiles, it is not anticipated that straw mulching will be necessary. In addition to the protections afforded by proper siting, planted grasses, volunteer growth, and mulch (if necessary), all topsoil stockpiles will have diversion ditches constructed around them if the possibility of erosion from surface water flow exists. Plan for Soil Storage -Kerr Tipple Area Since regulations in existence in 1974 did not require the salvag- ing of topsoil when the tipple was erected, no topsoil is now stockpiled for the reclamation program at the Kerr tipple. Topsoil currently located at the site will be segregated from the fill material during grading and reclamation operations, and will later be applied to the recontoured fill material surfaces immediately after regrading is completed. 780-67 as
