De I ~ CLAP,.ATION Denver, Colorado 80203 P ~ of Natural Resources Dear Dean: The purpose of this correspondence is to request an exemption from the requirement to pass runoff through a sedimentation dam from Eive areas of dis- turbance associated with Utah International, inc.'s Trapper Mine. The five areas are shown on the enclosed map as areas 1-5. All but one of the five areas have previously been discussed with Division personnel and were inspected by Roger Funston and Gerald Zimpfer during [he last State inspection of the mine on April 15. Area 2 was, in fact, described in Trapper's compliance plan of April 28, 1978, when we made our original formal small area exemption request. Each of [he five sites is characterized as follows: Area 1 This is a storage site Eor an ANFO silo. It's an area where the topsoil has been salvaged and a level pad prepared for trucks [o drive onto. The entire storage area encompasses 0.2 acres which drain northwest into an unnamed drain- age. This disturbance represents .02% of the 895 acre drainage i[ sits in. Out of the 895 acres in the drainage, runoff from 661 acres is treated before leav- ing [he permit area by passing through our Coyote Dam. Area 2 This is an area where mining "dayligh[ed" a[ the upper end of our Derringer Pit resulting in 14.3 acres of disturbance that drain to [he south [o [he Williams Fork River. As is evident from [he map, the disturbance is at the very crest of the divide and therefore, no runoff originates above to run through i[. Runoff occurs only as a direct result of precipitation. This disturbance repre- sents about 3.5% of [he 404 acre drainage i[ occurs in. Moreover, most of the runoff Erom the site must first pass through a small stock pond located near the downslope toe of the disturbance within our permit area. All of the disturbance draining to the Williams Fork has been regraded to the approximate original con- tour and will be retopsoiled and reseeded this year. In addition, a land imprinter will be run over the site after seeding to minimize runoff. IC should be noted [h a[ because of [he steep, deeply incised drainage, construction of a sediment dam and access road would result in significantly more disturbance than presently exists. Yip .
