`J`' <br />Are there any non-mining related disturbances created within <br />the permit boundaries by third parties (landowners, county <br />road crews, oil and gas drilling contractors, railroad crews, <br />etc.)? <br />No. <br />Describe how the site is marked or identified. Does <br />sufficient information exist to direct interested persons to <br />DMG? <br />The site is not adequately marked. The original Mine ID sign was <br />apparently vandalized and is no longer present. DMG is arranging <br />to have a sign made and erected at the site. <br />(ii) Whether, and to what extent, there exist on the site <br />impoundments, earthen structures, or other conditions that <br />pose, or may reasonably be expected to develop into, imminent <br />dangers to the health or safety of the public or significant <br />environmental harms to land, air, or water resources. <br />a) A highwall remains in place above the Fruita #1 bench, ranging <br />from 10 to 60 feet high. The vertical highwall was drilled and <br />blasted from competent sandstone and shale strata in the summer of <br />1977, and shows no sign of erosion, sloughing, or instability. <br />There is a 5 to 30 foot wide bench at the crest of the highwall <br />which would intercept rockfall material from the steep slopes <br />above. There are no protective structures such as fences or <br />guardrails safeguarding the highwall, but given the relative <br />remoteness of the site from populated areas, there would not appear <br />to be a significant safety risk to the public. The site does <br />receive use by hunters, target shooters, and other recreationists, <br />as evidenced by tracks, litter, spent shells, etc., mostly <br />concentrated on the relatively flat #1 Mine bench. Risks posed by <br />the highwall would not appear to be inherently greater than those <br />posed by sandstone outcrops and escarpments of similar height, <br />which are common in the Bookcliffs in the vicinity of the mine. <br />b) All portals at both the #1 Mine and the #2 Mine have been <br />backfilled and graded. The #2 Mine portal area was returned to <br />approximate original contour, while the #1 Mine portal area was not <br />returned to approximate original contour. Rather, the reclaimed <br />configuration is a narrowly "U" shaped, relatively flat bench, <br />approximately 150 feet wide at its upper end where the portals were <br />located, and approximately 300 feet wide at its lower end along the <br />crest of the outslope. The bench is approximately 350 feet in <br />length and is encircled by the highwall, with a steep (1.5:1 to <br />2:1) rocky fill slope below the bench, which extends for <br />approximately 400 feet to the narrow draw at its base. The actual <br />portal backfill slope at the upper end of the bench was graded to <br />an approximate 3:1 slope, extending for approximately 50 feet from <br />
