Mr. Jim Stover, P.E. July 16, 2008 Page 9 2.2-3. Our interpretation of the commitment is that the silt fence between the sediment pond location and the creek (depicted on Figure 2.2-3), will be installed prior to sediment pond construction and maintained until the sediment pond disturbance area is stabilized by an effective interim vegetation cover. Rule 2.06.8 Alluvial Valley Floors 59. The Division made several requests pertaining to updated alluvial valley floor boundary information pertinent to proposed TR-16 operations. All of the Items originally labeled as 59a) through 59e) have been resolved with exception of Item 59c), as set forth below: c) Please update the narrative description of existing and proposed disturbance on the AVF, on permit pages 4-6 and 4-7, of Section 4.1.2.5, to incorporate proposed TR-16 disturbances. Note that the existing narrative indicates (apparently erroneously) that "the existing sediment pond, topsoil stockpile, and proposed riprap storage area" are located on the AVF. New narrative was provided on amended pages 4-6 and 4-7, incorporating proposed TR-16 disturbances. The new discussion regarding acreage associated with the proposed disturbance is somewhat confusing, as there is a statement indicating that approximately two acres of disturbance will occur on the AVF, followed immediately by an accounting of 4.5 acres of disturbance associated with individual facilities. Based on Figure 4.1-2, some portion of the cited disturbance (e.g. the coal mine waste pile and some or all of the proposed new construction material stockpile) appear not to be located on the AVF. Please provide clarification regarding disturbed acreage on the AVF; disturbance acreages listed for individual facility disturbances on the AVF should add up to the total disturbance acreage on the AVF, and should conform with the AVF boundaries and facility disturbances as depicted on Exhibit 4.1-2. New Items A through E regarding revised figures submitted with the May 21, 2008 Response package are given below. A. Figure 2.2-1- Affected and Disturbed Areas The lease boundaries are clearly delineated by purple dashed lines, but the permit boundary is missing from this map. Please add the permit boundary. There is an un-labeled, mostly continuous red line that approximately follows the 5600' to 5800' elevation from north to south through the area shown. Please identify this line or remove it from the figure. B. Figure 2.2-2 - Surface Facilities The term "Gob Pile" is still used to identify the Coal Mine Waste Pile. Please correct the label. Page 2-32 describes Light Use Road #3, but we are unable to locate the road on this map. Please provide the location of Light Use Road #3.
