Ownership of the surface by private, Federal and State interests is 3,967.1, 70.2 and 55.7 acres, respectively. Mineral ownership is 3216.2 acres Federal, 821.1 acres private and 55.7 acres State. Permit Area acreage is not changed by PR- 4. Approval of PR-3 allowed for continued mining within the South Extension of the approved permit area. PR-3 approval authorized an additional 148 acres of disturbance to allow for recovery of Sage Creek and Wolf Creek reserves, and 14 additional disturbance acres associated with expansion of previously approved Wadge pit disturbance areas. Approval of PR-3 was projected to extend the period of mining within the permit area through 2011. PR-3 approval also provided for modifications to [he sediment control plan to handle the additional disturbance associated with the Sage Creek/Wolf Creek mining area. Additionally, the Division approved variances from the 180-day backfill and grading requirement of Rule 4.14.1(1)(c), for specific locations. Finally, within PR-3, the Division approved a number of reclamation plan amendments intended to enhance soil stabilization and vegetative diversity, and a field study to evaluate irrigation and soil handling practices for successful establishment of site-native aspen saplings. The primary operational change associated with PR-4 is the incorporation of highwall miner coal extraction to allow for maximal coal recovery following extraction by conventional surface mining techniques, in specified fmal pit locations.
