well above the required 1.5. <br />The Refuse Pile is located east of the King I Mine entrance, beginning just east of the <br />shop building and extending up the east side drainage approximately 900 feet (see Map <br />King I-007 in the PAP). An intercept channel (Reach 1 on Map King I-007) was <br />constructed north of the pile to divert flow from the undisturbed area around the site <br />and to Hay Gulch (via a series of culverts and channels that run along the east side of <br />the King I disturbed area). Similarly, a channel was constructed at the bottom (south <br />side) of the Refuse Pile to intercept runoff from the pile. This channel is Reach 10, <br />and it routes the water to the two sediment ponds at the lower end of King I. An <br />underdrain system was constructed beneath the Refuse Pile, and the two branches of <br />this system drain to a series of culverts and channels that lead to the sediment ponds. <br />B. The applicant has not submitted a plan for disposal, at the approved disposal area <br />within the permit boundary, of mine waste materials generated by activities outside <br />the permit boundary (4.10.1(2)). <br />C. The disposal area will be inspected on a regular basis by a qualified professional <br />specialist under the direction of the professional engineer, experienced in construction <br />of similar earth and waste structures (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 ensure the <br />applicable static safety factor, stability of the fill, and protection of the surface and <br />ground water (4.10.3(5)). <br />E. The applicant has submitted a demonstration based on physical and chemical analyses <br />that shows that revegetation requirements of 4.15 can be met with less than 4 feet of <br />cover on the coal processing waste bank (4.10.4(5)). <br />IX. Coal Mine Waste — Rule 4.11 <br />Non -coal waste will be stored at designated locations at the mine site, and then transported <br />to a disposal site by a licensed contractor. <br />22 <br />
