<br />~ 'I~Y6NTYM166 <br />~s COAI. COMPANY <br />A Cyprus Amax Company <br />April 1, 1997 <br />iiiiiiiiiiiniiiiii • <br />Janet Binns <br />Environmental Protection Specialist <br />Division of Minerals and Geology <br />1313 Sherman Street, Room 215 <br />Denver, Colorado 80203 <br />RE: Permit Revision No. 97-04 <br />Permit No. C-82-056 <br />Deaz Ms. Binns: <br />Twentymile Coal Corporation <br />29515 Routt County Road # 27 <br />Oak Creek, Colorado 80467 <br />970-879-3800 <br />RECEIVED <br />~~ 021997 <br />OWIlbf101 mmdre~a a auoioBy <br />Twentymile Coal Company is requesting a permit revision to the above <br />referenced permit. The revision, once approved, will allow continuation of <br />mining the remaining reserves in the eastern mine district and expansion into <br />the northern mining district, both of which are located inside of the approved <br />life of mine permit boundary. <br />The mining in the eastern mining district will see coal removed from longwal] <br />panels 6 Right through 2 Right and gateroads 4 Right through 2 Right. The <br />expansion into the northern mining district will see coal removcd from the <br />northeast submains, northwest mains, panels 12 Right through 16 Right (half <br />of the pane]), and gateroads 11 Right through 17 Right. As stated above, all of <br />this activity is within the existing life of mine permit boundary. Also, presently <br />there are no plans for construction of new surface facilities to accommodate the <br />continued mining in these areas. The existing surface facilities will be utilized <br />in the conveying, stockpiling, crushing, tippling and shipment of coal. <br />The plans were discussed with the Division and the comments received during <br />the meeting have been incorporated into the application. As noted during our <br />meeting, Map 23 A has been deleted from the list of maps and the information <br />presented on it, i.e. subsidence boundary projection, has been placed on Map <br />23. <br />It is anticipated that the review should go smoothly in view of the fact that this <br />is just an extension of the approved mine plan within the life oC mine permit <br />boundary. Also, Twentymile has been collecting data from the structures <br />undermined by panel 9 Right and has used this information in preparing the <br />application. During this period Twentymile has successfully undermined and <br />
