MANAGEMENT tv 5D R� �3 o� R�G�110N OMs�ph G PNp �E('t M�N1N On behalf of Bowie Resources, LLC, (BRL), enclosed is an application for a technical revision to further increase the size of the material storage area located east of the B- Seam portals. Technical revision no. 79 initially approved the material storage area expansion and the excavation of 8,000 cubic yards from the excess material stockpile. An additional 6,000 cubic yards will need to be excavated from the excess material stockpile in order to further expand the material storage area. Bowie proposes to utilize all of the material excavated from the excess material stockpile to supplement the volume of cover material available for gob pile numbers 2 and 4. The 14,000 cubic yard deficit of fill material for the B -Seam portals at final reclamation would mean the reclaimed ground surface would be about 1.9 feet lower than the original ground surface over the 4.5 acre disturbed area. Thirty -six inch diameter culvert C -7 was lengthened 270 feet with the approval of TR- 79. The culvert will need to be extended an additional 20 feet with the approval of this technical revision. Right of Entry The work will be performed on land owned by Bowie. Affected and Disturbed Area There will not be any increase in the affected or disturbed area. Cultural Resources Not required, no new disturbance.
