June 27, 2012 C- 1996 -083 /13owie No. 2 Mine SLB culvert pipe beneath the road that temporarily provides vehicular access to the Coverfill Pile (Photo 1). • Construction of Ditch D -D3, including the riprap lining, has been completed (Photos 2, 3 and 4). This ditch, which flows to Pond D, is located along the western edge of Gob Piles 44 and # 1. EXCESS SPOIL and DEVELOPMENT WASTE — Rule 4.09 Placement; Drainage Control; Surface Stabilization: Disposal of coal mine waste (CMW), which includes both coal processing waste and underground development waste, is presently permitted for four areas at the Bowie No. 2 Mine. Three of these, "Gob" Piles 41, 42 and 44, are located north of old State Hwyl33, and are presently active or have reached capacity. The fourth disposal area, Gob Pile # 3, has not yet begun to be utilized due to difficulties with obtaining an emissions permit from the Air Pollution Control Division of the CDPHE. Rule 4.09 addresses disposal of excess spoil, and also applies to placement of CMW. The general requirements of section 4.09.1 are applicable to all three of the active CMW disposal areas. Gob Pile 42 is also governed by the additional requirements of Section 4.09.2, Valley Fill. PROCESSING WASTE /COAL MINE WASTE PILES — Rule 4.10 and 4.11 Drainage Control; Surface Stabilization; Placement: • Rule 4.10 Coal Mine Waste Banks and portions of Rule 4.11 Coal Mine Waste are applicable to Gob Piles #1, #2 and #4. The majority of coal mine waste being placed in the mine's gob piles is generated from the coal wash plant. As a result, the material is wet, and must be allowed time to dry before being permanently placed and compacted. During the preceding winter, BRL accumulated an excess of wet CMW on both Gob Pile 42 and Gob Pile 44. BRL has made substantial progress on Gob Pile 44 with placement of the CMW reestablishing the approved slopes and benches (Photo 2). • Numerous pieces of equipment were active on Gob Pile 42 on June 27 — in Photo 1, one excavator, two sheepsfoot rollers, a bulldozer and a water truck are visible. • Slopes on the southeastern flank of Gob Pile 42 have been grade - staked, in preparation for placement of coverfill material (Photo 5). SUPPORT FACILITIES - Rule 4.04: Access to the Terror Creek Shaft site was accomplished by way of the Terror Creek Access Road. Construction of the shaft is essentially complete, the contractor was preparing to pull out and relocate equipment and personnel to a project in the southeastern U.S. The drilled shaft is 20 feet in diameter. It is lined with concrete 1 foot thick, resulting in an inside diameter of 18 feet. Placement of the concrete lining was accomplished 10 feet at a time, and proceeded from the top, downward. The forms, together with an adjustable working platform (Photo 6) were reset with each segment, for an overall depth of 500 feet. A head frame was still in position over the top of the shaft (Photo 7). • The shaft will be fitted with an escape pod that can be used by mine personnel in the event of an underground emergency. • Construction of the shaft site required cutting into the hillside. The cut slope was stabilized using a soil nail wall system (Photo ), similar to that used in the repair of Haul Road Curve No. 11 in 2008 (TR -55). Mr. Bear was unsure whether the wall faces at the shaft site would be sprayed with shotcrete.
