TR -72 <br />proposes to add a small (0.52 ac) area of additional watershed that will drain into Pond 018 and proposes to <br />change the location of the combination spillway from the approved southern embankment of the pond to the <br />southwestem corner of the embankment. Based on the TR -72 submittal, the Division believes that the criteria <br />utilized for the Pond 018 redesign is adequate to meet Rules 4.05.3 and 4.05.6. As such, the Division believes <br />that the activities proposed under TR -72 are adequate. <br />Please let me know if you have any questions or comments. <br />Thanks, <br />Jason <br />Jason Musick <br />Environmental Protection Specialist III <br />Coal Regulatory Program <br />COLORADO <br />Division of Reclamation, <br />Mining and Safety <br />Department of Natural Resources <br />P 303.866.3567 x 8134 1 F 303.832.8106 <br />1313 Sherman Street, Room 215, Denver, CO 80203 <br />jason.musick@state.co.us I http://mining.state.co.us <br />https://mail.google.com/mail/W0/?ui=2&ik=e29129fcb5&view=pt&search=inbox&th=154bf397cb68acf2&siml=154bf397cb68acf2 1/1 <br />
