WESTERN <br />FUELS <br />ASSOCIATION <br />ING <br />AeNational <br />Fuel Supply <br />Cooperative <br />RECEIVED <br />FEB 11 2011 <br />Q? <br />usv?.>, ?; ,,,,,,jamawn, <br />Mining and Safely <br />February 10, 2011 <br />Ms. Sandy Brown <br />Senior Environmental Protection Specialist <br />Colorado Division of Reclamation, Mining and Safety <br />1313 Sherman St., Room 215 <br />Denver, CO 80203 <br />RE: AMENDEDMENT TO NOI X-2008-142-12 TO DRILL THREE <br />SAMPLING HOLES <br />Dear Ms. Brown: <br />Western Fuels-Colorado (WFC) hereby requests DRMS approval to drill additional three <br />holes under NOI X-2008-142-12. WFC is submitting this request pursuant to DRMS <br />recommendation in the February 1, 2011 meeting in Grand Junction. The referenced NOI <br />was approved to drill twelve water monitoring holes. Only nine monitoring holes were <br />drilled. Please see the attached letter from DRMS acknowledging the receipt of reports <br />required after the end of the drilling activity. The three monitoring holes are currently <br />being used to collect field parameters and water samples. A $6,063 reclamation bond is <br />still in effect under this NOI. <br />WFC is planning to drill three (3) new holes in the proposed New Horizon North (NHN) <br />Mine permit area to provide geochemical data for the overburden, coal and interburden <br />strata that will be mined at the proposed NHN Mine. This data will supplement the <br />information that has been provided in the NHN Mine Permit application which has been <br />submitted to Colorado DRMS and for which the adequacy review process is in progress. <br />The purpose of the supplemental chemical analyses of overburden, coal and interburden <br />samples is to identify any acid-forming, toxic-forming, alkalinity producing, or other <br />inhibitory materials present within the proposed mine boundary. Physical properties of <br />the overburden, coal and interburden will also be determined to define compaction, <br />stability, permeability, erodibility, and water holding characteristics. Chemical and <br />physical analyses also reveal the most desirable overburden strata to be placed at the spoil <br />surface and in the pit bottom. This information is required to effectively prepare a mine <br />plan that restores the landscape, vegetation productivity, and which also minimizes <br />environmental degradation. The overburden, coal, and interburden samples will be <br />submitted to a laboratory that will perform sample analyses as per the specifications <br />contained in CDRMS, Guidelines for the Collection of Baseline Water Quality and <br />PO Box 33424 - Denver, CO 80233-3424 - Telephone 303/254-3070 ¦ Fax 303/254-3079 - 1100 West 116th Avenue - Westminster, CO 80234
