Planting and Seeding Methods <br />. EFMC will generally use one of two seeding methods dependant upon the nature and <br />aspect of the azea to be reclaimed. Drill seeding with a conventional rangeland seed drill <br />will be utilized for most reclamation work. Using the seed drill, the seed mixture will be <br />seeded at a rate of 12.6 pounds of pure live seed per acre. To the extent possible, EFMC <br />will seed along the contour in order to establish lineaz contour line features which help to <br />break-up sheet runoff and minimize the potential for rill and gully erosion. <br />In azeas where drill seeding is not practical due to the limited size of the disturbance azea <br />or slope gradients which would limit normal equipment operation, hydroseeding or <br />broadcast seeding will be utilized. Hydroseeding involves distribution of a mixture of <br />seed, mulch and tackifier over the area to be reseeded and can be effectively utilized on <br />relatively steep slopes where the mulch tackifier forms a protective matrix which holds the <br />seed on the slope until it can germinate and establish. Where hyrdroseeding or broadcast <br />seeding is utilized, seeding rates will be increased to 25.2 pounds of pure live seed per <br />acre, or twice the normal drill seeding rate. <br />Mulchine <br />Immediately following seed planting (except where hydroseeding is utilized), the entire <br />area will be mulched with grass hay or cereal grain straw at a rate of 4000 pounds per <br />acre. A mulcher capable of blowing the mulch, to cover the slopes, will be utilized. <br />• Crimping will be accomplished using a disc and will serve to anchor the mulch. <br />I~g 'on Pest and Disease Control Methods <br />No irrigation is planned for the reclaimed azeas. <br />If and when pest or disease problems become evident on the reclaimed area, EFMC will <br />consult with the Division before implementing control measures. <br />Methods of Determining Success of Reve lion <br />Revegetation goals for the Raton Creek Mine site were determined from vegetation cover <br />and productivity data gathered in 1982 and submitted to the Division in September 1982. <br />Specific goals were established in a meeting between the Division and Sundance Coal <br />Company on August 9, 1983, and in subsequent discussions. The minimum standards <br />established for successful revegetation aze as follows: <br />Vegetation Cover 25 percent <br />Vegetation Production 300 pounds per acre <br />Shrub Density 500 stems per acre <br /> <br />52 L Revised: 2/27/98 <br />A4iaos_Re~isiea-q+5-^ <br />~N-a3 9-8-`lc~ <br />
