been approved by the Division as appropriate (4.10.2(1)). <br /> D. An alternative sub-drainage system for the coal mine waste area has not been <br /> proposed. The Division finds that the approved sub-drainage system will <br /> ensure the applicable static safety factor, stability of the fill, and protection of the <br /> surface and ground water (4.10.3(5)). <br /> F. The applicant has submitted a demonstration based on physical and chemical <br /> analyses that shows that revegetation requirements of 4.15 can be met with less <br /> than 4 feet of cover on the coal processing waste bank (4.10.4(5)). <br /> IX. Coal Mine Waste <br /> Non-coal waste will be stored at designated locations at the mine site, and then <br /> transported to a disposal site by a licensed contractor. <br /> X. Backfilling and Grading <br /> The previously approved plan for backfilling and grading of disturbed areas is <br /> described in Section 2.05.4 of the permit application. Maps King I-011 and King II- <br /> 010 show approved post-mining contours. <br /> When no longer needed for the mine's operations, benches at King I will be backfilled <br /> to a stable configuration that blends with the surrounding topography. Based on <br /> information provided by GCC, pre-mining contour maps of the King I Mine do not exist <br /> due to the length of time the mine has been in operation (more than 50 years). <br /> Backfilling of the King I Mine will involve reducing all mine bench highwalls and the <br /> bench outslope crest to approximately 1.5 h:Iv and in most areas to 2.5h :lv, or less, <br /> to blend in with surrounding areas. The portal area of the King II Mine and all other <br /> disturbed areas on this mine will be reclaimed to approximate original contour. <br /> XL Revegetation <br /> A. Information pertaining to baseline vegetation and revegetation is presented in <br /> Section2.04.10 and in Section 2.05.4, respectively. <br /> A pre-mining vegetation inventory was not performed on the King I Mine because <br /> the site was disturbed in 1941, prior to any requirements for such surveys. In lieu <br /> of this, NKC provided a description of areas next to the King I Mine having <br /> vegetation types similar to what is believed to have been disturbed. Three <br /> vegetation communities were identified: mountain shrub, pinon-juniper, and <br /> introduced pasture. The introduced pasture was disturbed by the haul road at the <br /> King I Mine; whereas, the mountain shrub and pinon-juniper communities were <br /> disturbed by the surface facilities area. <br /> 21 <br />
