had a solid north-south ridge (Tr.-I, 51). The plan that Kerr <br />complied with left an east-west notch or depression in the ridge <br />(Tr.-I, 73). However, there are broken ridges in the vicinity of <br />the mined area similar to the ridge in its present form (Tr.-II, <br />289-90, 290, 293, 295, 313, 315-18, 398-400; Tr.-7II, 448). In <br />addition, Randall Price of DMG testified that if the ridge were <br />restored to pre-mining condition, he would have concerns about <br />stability, and prior to requiring any change in contour, he would <br />do a stability study (Tr.-II, 392). <br />The notch in the final contour also made a change in the <br />drainage system; 15 acres of drainage that used to drain east <br />into the Canadian River, now drains through the Bush Draw into <br />the Canadian River (Tr.-I, 142-43). However, this change did not <br />significantly affect the drainage system and the site has posi- <br />tive drainage (Tr.-II, 309, 381-82). <br />Based on these above-described differences from the pre- <br />mining condition, OSM found that Kerr had not met AOC standards. <br />Basically, OSM's position is that the land actually mined must be <br />returned to premining condition (Tr.-I, 86, 167-68). That is, <br />Kerr must put the ridge generally back to its pre-mining eleva- <br />tion and slope (Tr.-I, 167-69). OSM concedes that there is no <br />imminent danger to the public or imminent harm to the environment <br />caused by the asserted AOC violation (Tr.-I, 103). <br />-12- <br />
