<br />length of approximately 250 feet. Three slope angle measurements were taken with a <br />Brunton compass level, on a baseline bearing 270°. Measurements were taken <br />approximately 100 feet apart. All three slope angle measurements were 15.0° and thus <br />were all gentler than the approved maximum reclaimed slope angle of 18.43°. <br />The slope at the western edge had an eastern aspect, a vertical slope length of <br />approximately ten feet, and a horizontal length of approximately 100 feet. One slope <br />angle measurement of 16° was taken, which was gentler than the approved maximum <br />reclaimed slope angle of 18.43°. <br />B. Office/Parking Lot Area <br />This area consisted of a disturbance of approximately 30,000 squaze feet in extent. It <br />was comprised of two regraded slopes situated immediately adjacent to each other, with <br />one slope situated immediately north of the other. The grade of the southern slope was <br />gentler than the grade of the northern slope, as it was the site of the former mine office <br />building and parking lot. Both slopes had northern aspects. <br />The tce of the southern slope forms the crest of the northern slope. The northern slope <br />is part of the south bank of the east-west oriented refuse collection ditch, built at the <br />base of the refuse pile that lies to the north of the ditch. <br />The northern slope measured approximately 200 feet by 80 feet. The southern slope <br />measured approximately 450 feet by 30 feet. Both slopes had their shorter vertical <br />(downslope) axes oriented north-south, and their longer horizontal axes oriented east- <br />west. <br />A 300-foot tape was extended in an east-west direction near the southern edge of the <br />southern regraded slope. Slope measurements of both the northern and southern slopes <br />were taken along bearings shot north (perpendicular) from the tape, at points 50 feet <br />apart along the tape. Seven slope angle measurements were taken on each of the two <br />slopes, using a Brunton compass level and a £ve-foot measuring stick. For the <br />southern slope, these were 4.0°, 3.5°, 2.0°, -1.0°, 1.0°, 0.5°, and 0.5°. For the <br />northern slope, these were 4.0°, 11.5°, 13.5°, 11.0°, 10.5°, 10.0°, and 13.0°. All <br />14 measurements indicated that the regraded slope angles had been constructed gentler <br />than the maximum approved regraded angle of 18.43°. <br />C. South-Facing.Siope of Refuse Collection Ditch <br />This area consisted of a disturbance of approximately 9000 square feet in extent. It <br />consisted of a single regraded slope with a southern aspect. Its shorter, vertical <br />(downslope) axis was oriented in a north-south direction, with its longer, horizontal <br />axis oriented east-west. The horizontal axis was approximately 150 feet in length, and <br />the vertical approximately 40 feet. <br />A 300-foot tape was extended along the longer east-west axis, with four slope angle <br />measurements taken every 50 feet. These four measurements were 10.0°, 11.0°, <br />3 <br />
