lames A. Kilter <br />November 22, 2000 <br />Page 3 of 5 Pages <br />notice, and indicate to the Division in writing whether Colowyo ever submitted a bond for <br />their reclamation. <br />Item 5 Availability of bond coverage for thirteen, and increased bond coverage for another 12. <br />exploration holes is discussed in documentation associated with MR 12, and reclamation cost <br />estimates for drill holes permitted under MRs 12. 27, 31, 34, 35 and 40 appear in the cost estimate <br />(Exhibit 13) of Permit Renewal 03. However no bond release documentation required by Rule <br />3.03 for these holes has been located. Your TR-50 application, along with the associated NOI <br />application, applies for bond release for those wells (current) listed on Table 1. As outlined above, <br />the Division proposes that bond release be documented for all exploration holes under your NOI <br />application associated with TR-50. Please add holes IP#1, IP#2 and IP#3 (MR 34) to the 89-97 <br />Map and add them to Table 1 (mined through). <br />Item 6 Please add the "other holes" in the immediate pit areas [reference Colowyo letter of <br />May 7, 1997, Re: 1997 Drill Hole Exploration Within the Permit Area Request For Minor <br />Revision, MR-(44) Colowyo Coal Company L.P. (C-81-019)] to the 89-97 Map and to Table 1 <br />(mined through). <br />Item 7 The Permit Area 1989-1997 Drill Hole Information Map includes a hole 89-10-6. Please <br />include this hole in Table 1. It has likely been mined through. <br />Item 8 Table 1, last revised 7-18-00 indicates that hole UL-95-40 was mined through. This may be <br />an error. If so, please correct Table 1. <br />Item 9 Please modify Section 2.02.2 (page 2.02-1), end the section "Sealing of Exploration <br />and Mine Holes" on page 2.05-59, modify page 4.07-1, and add to page 4.21-3 of the PAP a <br />statement (to the effect ofj that "Effective with Technical Revision 50, exploration holes <br />within the Permit boundary are transferred to NOI X-95-109-5, and are managed under <br />Coal Exploration procedures. See the appropriate Notice of Intent (NOI) for information on <br />these drilled holes. Wells drilled as an integral part of water monitoring plans identified in <br />the PAP (Permit C-81-019) and water supply wells (for mining purposes) are managed <br />under this permit C-81-019." <br />Item 10 Please address the apparent discrepancies regarding wells UL-95-40, UL-95-40A, <br />UL-95-45, and UL-95-45A in the PAP, Table 1, and the Well Locations map (12-10-96). <br />Holes UL-95-40 and UL-95-45 were permitted as coal exploration sites in MR 31. Additional <br />wells UL-95-40A and UL-95-45A were permitted to be drilled at the same sites in MR 35. Table 1 <br />indicates that holes UL-95-40 and UL-95-45 were sealed, and that UL-95-40A and UL-95-45A are <br />licensed (Office of the State Engineer) as monitoring wells. However, holes UL 95-40 and UL 95- <br />45 (rather than UL 95-40A and UL 95-45A) appear on the Well Locations map, and the Engineer <br />licenses apply to wells UL-95-40 and UL-95-45 (rather than to UL 95-40A and UL 95-45A). <br />
