Revised: 07/26/90 <br />WALDEN COAL COMPANY - RILL & GULLY RECLAMATION PLAN <br />• Due to the type of soils present on the Bourg Mine property <br />and the nature of precipitation events common in North Park during <br />the spring and summer months, the potential for the formation of <br />some rills and gullies in the post-mined topography is great. In <br />light of this, Walden Coal Company hereby submits the following <br />rill and gully reclamation plan to be implemented in the case of <br />excessive rilling and/or gullying at the Bourg property. <br />Walden Coal Company personnel will make a minimum of two <br />inspections per year of aII reclaimed areas to determine if <br />excessive rilling or gullying has occurred. one inspection will <br />be conducted in the spring after the snowmelt runoff and the <br />second inspection will be conducted in the late summer or early <br />fall to coincide with the required vegetation and water sampling. <br />If excessive rillying or gullying, as defined by "The Mined Land <br />Reclamation Division's Policy on the Management of Rills and <br />Gullies," is identified, the following remedial steps shall be <br />taken: <br />1) Notify MLRD of the problem. <br />2) Assess the extent of the problem indicating location and <br />amount of area affected on a map and noting type of erosion. <br />• 3) Determine the appropriate remedial action. This may <br />include raking, retopsoiling, reseeding, reshaping, addition <br />of rip-rap, hay bales, or small check dams, or other action <br />as appropriate. <br />4) Correct the problem at a time when weather, soil, and <br />vegetation conditions permit during the first growing season <br />following identification of the problem. It is essential <br />that the reclaimed area not be further damaged in an attempt <br />to fill in rills and gullies. <br />5) Notify MLRD when all steps have been completed. <br />Management of Permanent Gully <br />The permanent gully on the Bourg property will be managed <br />according to the above Rill 6 Gully Reclamation Plan. The gully <br />has been graded, rip-rap has been added, and the area has been <br />reseeded. Walden Coal Company anticipates that with the <br />above-mentioned remedial actions the permanent gully will <br />experience normal as opposed to excessive erosion in the future. <br />• i <br />~~ <br />R~Zo~ao <br />F-12{a) <br />
