III IIIIIIIIIIIIIIII 999 Colowyo TR-50 Issues TR-50 background TR-50 seeks to transfer a number of borehole drilling sites approved to be constructed within the Colowyo Mine permit area to Colowyo NOI X-95-105-05. Colowyo has additionally submitted an application to Jim Burnell to amend this NOI to add these borehole drilling sites to the NOI. Colowyo has also submitted to Jim Burnell a request for a full bond release for this same NOI, to release all the borehole drilling sites associated with the NOI, including the ones transferred to the NOI via TR-50. TR-50 has requested transfer of 70 borehole drilling sites to the NOI. There are, however, actually more than 70 sites, as explained below. Colowyo listed these sites in Table 1 of TR-50. Colowyo also submitted a map depicting the locations of these drilling sites. The borehole drilling sites that are the subject of TR-50 are composed of sites where: (]) boreholes were never drilled; (2) boreholes were drilled, left unreclaimed, and mined through; (3) boreholes were drilled, reclaimed, and mined through; (4) boreholes were drilled and reclaimed; (5) boreholes were drilled and covered over by an excess spoil fill; and (6) boreholes were drilled and completed as water monitoring wells for gathering data in conjunction with a future mine expansion. Some of these borehole drilling sites were situated within mine pits or other previously disturbed areas, while other sites were not. Some sites were approved to have two boreholes per site. One of the two holes was a "pilot" hole, and the other a "core" hole. Some of the borehole drilling sites were bonded, and some were not. Some, but not all, of the two hole sites were bonded for the reclamation of both holes. PermittingBonding History of Exploration MRs The Colowyo Mine permit contains language that allows the permittee to construct 13 borehole drilling sites in advance of mining. Colowyo had posted an individual $8800 mine bond, separate from [he overall mine bond, to cover the cost of reclaiming these 13 sites. MR-12 approved 25 coal exploration drilling sites. Seventeen of these were beyond the mine's five-year mine plan area, while the remaining eight were within the five-year area.
