Box 774288 <br />Steamboat Springs, CO 80477 <br />(303) 879-3800 <br />June 13, 1983 <br />~{ ~. ~..r ~ ~d` .w <br />!UII l ii 183 <br />-v9lPJED LP.rJJ NECLAiN~TiOtd <br />Golo. Dept. o. P~aa;ial ge50~rr.e~' <br />Listed in the April and May Inspection Reports for Mine 1,2,3 and <br />Eckman Park are three compliance schedules: (1) Rills and gullies (2) <br />gully stabilization at Mine 3, and (3) completion of t'::e permanent ditch <br />around Overburden Stockpile d)1. Below is a listing of these concerns and <br />CYCC's responses. <br />83-4. A plan to stabilize rills and gullies greater than nine inches <br />deep, a demonstration that rifling and gullying is not excessive and is <br />consistent with the approved postmining land use or a combination of both <br />shall be submitted by June 15, 1983. <br />Response: As discussed between CYCC and representati~.•es of CMLRD, the <br />existing problems of rills and gullies are not exclusive to this mining <br />~'- operation. The CYCC proposes initially to leave the erosion area s alone <br />to determine if an acceptable amount of vegetation cover becomes -no.

As a ',., A„~.cLZy 4{ <br />preventative measure diversion ditches will be installed where deemed o~~~~,y,~„{,,,,lntli. <br />necessary. After onitoring,~f an area is deemed not to have enough <br />~~ <br />vegetative cover to control erosion, the rills and gullies will be filled Z <br />and seeded and diversion ditches maintained to control water flow on the <br />site. <br />83-1. Submit a plan to stabilize the gully that has formed on the <br />regraded surface mine area by June 15, 1983. <br />Response: Prior to topsoil reapplication at Mine :' the area will undergo <br />a final spoil grading process. At that time the irrigation ditch halfway-Y10 mks+ ~ <br />-'~,ay up the slope will be reestablished and t e spoil above the ditch regraded clone -t1v, <br />1~ so that water will have a dispersed flow instead of a concentrated flow. s-^v^'-~iD <br />Q-a~,. <br />82-14. The permanent diversion ditch around Overbrrden Stockpile ~kl must <br />be redesigned and constXucted this summer. ' <br />
