The following summarizes the history of modifications to the R2P2: <br />Modification Submittal Date Description <br />MOD1 11/04/96 7-Right Inby Cross-Panel Entries <br />MOD2 01/21/97 Adjust Recoverable Reserve Estimate <br />MOD3 06/17/97 6-Right Cross-Panel Entries <br />MOD4 08/12/97 6-Right Inby Cross-Panel Entries <br />MOD5 08/12/97 6-Right Gateroad and SE Submains <br />MOD6 10/27/97 Adjust Reserves for Panels 8 and 9-Right <br />MOD7 07/02/99 Extension of 2 and 3-Right Panels <br />MOD8 01/26/00 Realign Northwest Mains <br />MOD9 08/01/00 Recovery of Additional Reserves <br />MOD10 10/26/08 Northern and Western Mining District Reserves <br /> Panels 24-Right and 13- through 16-Left <br />This modification addresses ongoing development and future longwall mining activities in Panels 14- through 17-Left of <br />the Western Mining District (WMD), with preliminary development (in other federal leases or State or fee coal) addressed <br />by previous revision submittals to and approvals by the Colorado Division of Reclamation, Mining, and Safety (CDRMS). <br />The Office of Surface Mining, Reclamation, and Enforcement (OSMRE) is also reviewing the development and mining <br />plans for the referenced Federal Coal Lease (COC-72980) as a Federal Mine Plan Revision, since the proposed <br />development and mining activities will represent the first mining in Federal Lease COC-72980. The attached table <br />provides reserve estimates for each of the affected mining areas in the referenced lease, and the location of mining relative <br />to the lease blocks is shown by the attached figure.
