<br />Received <br />Description of Corrective Action <br />September 2001 <br />Yule Quarry <br />Mine ID # M-1999-058 <br />Introduction <br />OCT 1 2 2001 <br />Drew o ~ er~1s 6 Geo off, <br />On July 3, 2001, Mr. Bob Oswald, of the Colorado Division of Minerals and Geology, <br />visited the Yule Quarry. The visit was in response to receiving a citizen complaint (from <br />Steve and Kim McIntyre, owners of property adjacent to the Yule Quarry) about possible <br />damage due to Sierra's possible failwe to contain marble wastes within the permit azea. <br />Bob found that Sierra had allowed uncontrolled runoff and sedimentation to affect areas <br />adjacent to the mine access road and Bob described the corrective action necessary to be <br />completed by September 30, 2001. Dwing August and September, Sierra completed <br />work on the roadway as required in Bob's findings. <br />Corrective Action Required <br />In his report Bob Oswald required the following corrective action: "The operator must <br />remedy the inadequate drainage pattern and runoff control structwes on the roadway, <br />such as: directing runoffto the inside road edge, discontinuing use of fines as an earthen <br />berm material, and replace missing barriers by something more substantial or <br />appropriate." <br />Road Work Performed <br />Before the improvements were made, the road had been sloped outward. Any storm <br />runoff tended to flow to the outside of the road, through gaps in the jersey barriers and <br />over the edge. Sierra had attempted <br />to keep this runoff from going <br />through the jersey barriers by <br />placing fines from the quarry along <br />the base of the barriers. However, <br />this resulted in small quantities of <br />the fines being carried over the edge <br />with runoffand the subsequent <br />complaint by the McIntyres. <br />
