•• (Page 2) •• <br />MINE ID # OR PROSPECTING ID # M-77-484 <br />INSPECTION DATE 04/01/99 INSPECTOR'S INITIALS AJw <br />OBSERVATIONS <br />This inspection was conducted by Tony Waldron of DMG at the request of the operator to <br />determine if this site would be eligible for full performance warranty release. The site is <br />located approximately 7 miles west of Springfield, Colorado. <br />The site was last inspected in 1997 and at that time the inspector noted that serious erosion <br />was occurring on the regraded pit slopes. The condition has not improved much to date and <br />some work still needs to be done before this site will be eligible for release. The slope <br />grade appears to be 3H:1V or flatter and should support vegetative establishment, however, <br />there are numerous rills present throughout the backfilled area. There is some vegetation <br />growing inbetween the rills where the soil has not eroded down to the pit bottom but it has <br />not filled in to the point that it is stopped the rill erosion from occurring. The operator <br />was planning on filling in the rills with bedding straw from the county fair to try and slow <br />down or stop the erosion. This may help some but the slopes really need to be regraded or <br />filled in with additional topsoil and seeded to completely stop the erosion. When this has <br />been completed the operator can contact the Division to re-inspect the site for a possible <br />release. In the mean time, the erosion is going to be cited as a problem on page three of <br />this report along with appropriate corrective actions. <br />Suggestions would be to haul in additional soil and fill in the rills and gullies and re-seed <br />before spreading out the straw that is stockpiled on site. If a reliable supply of soil <br />cannot be easily obtained, the existing soil on site should be respread over the sloped areas <br />before re-seeding. The seed mix currently contains only two species of grass. This should <br />be revised to include several additional grasses such as sideoats grama, bufEalograss, <br />switchgrass, galleta, intermediate wheatgrass, little bluestem, etc. This should provide an <br />opportunity for better vegetative establishment. The installation of an upland diversion <br />ditch around the top of the pit may also help by preventing excessive flows over the sloped <br />areas where the worst rill erosion is occurring. Also, once the rills are regraded, the <br />placement of some contour furrows may help to prevent new rills from forming until the <br />vegetation becomes established. <br />As previously stated, once the rills are repaired and seeded, the site could be re-inspected <br />for performance warranty release. <br />I & E Contact Address <br />NAME Charles Wait <br />OPERATOR Baca County <br />STREET P.O.
