r ` <br /> Ms. Candace Thompson <br /> May 20 , 1985 <br /> Page two <br /> The portion of the old pile that was constructed after 1977 will <br /> be inspected each spring after snow-melt has occurred for any <br /> rills and gullies. If any are noted, temporary control will be <br /> established by hay bales or parts of bales being placed at prudent <br /> intervals along the rill or gully. When the refuse pile dries <br /> out (generally July or August) mechanical methods will be utilized <br /> to remove or fill the rills and gullies. In some cases (steep <br /> slope areas) soil conservation type log or rock check dam structures <br /> will be utilized. All disturbed areas will be reseeded and <br /> mulched. <br /> Tunnel Rock Pile <br /> Most of the pile is now completely covered with rock or will be <br /> by the end of 1985 (previously, portions were used on a temporary <br /> basis for coal preparation plant refuse) . It is believed very <br /> little rill and gullying will occur before topsoiling will take <br /> place (some in 1985, 86 , 87) . As topsoil is placed, the same <br /> program as described on the old refuse pile will be used. Any <br /> rill and gullying occurring before topsoiling will be addressed <br /> each summer with mechanical equipment as the pile dries out. <br /> New Coal Refuse Pile (Sutey) <br /> As the pile progresses upward a 2 to 1 outslope will develop. <br /> Before topsoiling occurs (probably 5 to 6. 5 years) the area will <br /> be inspected each spring and any rills and gullies noted. As the <br /> area dries out, mechanical equipment will be used to reshape the <br /> area. After topsoiling occurs the same program as described on <br /> the old refuse pile will be used. <br /> Please contact me if you have any questions. <br /> Sincerel , <br /> Dou owman <br /> Environmental Coordinator <br /> Mid-Continent Resources, Inc. <br /> P.
