1.0 Introduction <br />The Trapper Mine is a coal surface mine located on [he north slope of the <br />Williams Fork Mountains about 6 miles south of Craig, Colorado. Coal is <br />dipline mined using three draglines for overburden and interburden <br />removal. The mine produces up to 2.8 million tons of coal annually and <br />employs up to 360 people. The expected life of the operation is about 35 <br />years. The majority of [he coal is delivered to a mine mouth power plan[ <br />operated by Colorado-Ute Electric Association. Up [o .5 million tons of <br />coal per year are sold on [he spot sales market and transported out by <br />rail. <br />This report addresses potential alluvial valley floors (AVFs) that could <br />be affected by the Trapper Mine as required by the Surface Mining Control <br />•~ and Reclamation Ac[ of 1977 and the Colorado Surface Coal Mining Reclama- <br />tion Act of 1979. A review of potential AVFs associated with or adja- <br />cent [o Trapper Mine has been made in acccordance with 30 CFR 785.19(c). <br />This review has been accomplished from two perspectives. Firs[, the <br />presence or absence of AVFs was established [o the extent possible using <br />available information. Second, the potential for Trapper Mine to impact <br />any AVFs, if present was evaluated. This approach was intended [o <br />minimize unnecessary, detailed studies for potential alluvial valley <br />floors if [here is no probability of an impact and determine the need, if <br />any, for further investigations. <br />.! <br />-1- <br />
