Dept. of Nat~raf Aesa~rrF,~ <br />!!r. C. Patrick C.srrico <br />Ohio Creei: Coal Mina <br />P.O. Box 1058 <br />Gunnison, Colorado X1230 <br />Dear Mr. Carrico: <br />i7e have evaluated the proposed modifications to the federally-approved mine <br />plan for the Ohio Creek No. 2 Coal Mine to determine whether the proposed <br />action is a "major' modification. I have determined that the modifications <br />proposed (1) to reconstruct and enlarge the existing retention pond, (2) to <br />construct additional sediment control facilities, (3) to install a subsidence <br />monitoring network, and (4) to dispose of "gob" rock. ate minor modifications. <br />Since the Ohio Creek lip. 2 Mine received approval from the Geological Survey <br />(1973) to mine the coal in Lease lip. C-069942 and the area immediately north <br />of the lease and south of a projected fault, the proposed mining of the coal <br />is considered to be an implementation of the previously approved plan. <br />I must emphasize that .to mine any coal outside of this approved area by Ohio <br />Creek Coal and/or aay•other.operator will require the submittal of a new <br />proposal to the Department. <br />I have also determined, based on staff reviews and other Cepartmental and <br />State evaluations of potential compliance of the Ohio Creek Ho. 2 dine <br />proposals with 30 CFR 211, that the acce~tahle, provided I receive <br />your written acceptance of t stipulations contained iii Attachment I. <br />This letter is therefore, approval for you to undertake the construction of <br />the proposed actions providing the stipulations (.attacoent I) are accepted. <br />The proposed actions ccnsist of the inetallatioc of n subsidence monitorins <br />i <br />CONCURRENCES <br /> C" <br /> <br />.. .u <br />~. <br /> <br />. <br />_. <br />. .._ <br />,1/' <br /> <br />Ti ..._........ <br />..r <br />~ R + <br />~~:. .. <br />... <br />._ <br />.._.~ <br /> <br /> <br />...................._....... <br /> <br /> <br />.... .. ..... .. <br /> <br /> <br />... <br />.. <br /> <br /> <br /> <br />... ... .. ...... .. ..... <br /> <br /> <br /> <br />............ ... .... <br />1TE I u~.sn~, ' , If~~i 'L4 i <br />~' I ' I OFFICIAL FILE COPY ' <br />' pro ..u.z l <br />
