The Division has no further concerns. Appendix A was revised in the October 1, 2009 submittal <br />with a new topsoil replacement depth of 0.9 feet. <br />14. Based on a review of proposed Maps 15-3, Sheet 3 of 4, Mine Facilities and Volume LY, Figure 1, <br />Coal Mine Waste Disposal Area, there appears to be a possible increase in the disturbed area of <br />the mine. There is an undisturbed area that is surrounded on the west by Gob Pile #1, on the east <br />and south by topsoil stockpiles and on the north by Gob Pile #4. The expansion of Gob Pile #4 to <br />the south (to the lower elevation) pushes into this undisturbed area. The Division digitized this <br />area and found that it decreased from 1.65 acres to 1.05 acres. Additionally, there is a small area <br />to the north of Gob Pile #4 where the pile has pushed into the undisturbed land above (as the <br />piles maximum height increases and its shape changes from an angular one to a more rounded <br />one). Please review the changes to the pile as they relate to the surrounding undisturbed lands <br />and update the revision application to reflect any changes as necessary. <br />The Division has no further concerns. In the October 1, 2009 submittal, BRL provided revised <br />acreage figures in the TR-64 application and a revised disturbed area boundary on Map 18. <br />15. Based on a review of Volume IX, Figure 1, Coal Mine Waste Disposal Area, the horizontal scale <br />of the inset cross-section B-B' has been changed and appears to be in error. The horizontal scale <br />on the currently approved figure is shown as 40 feet/inch. The horizontal scale on the revised <br />figure is shown as 100 feet/inch. This changes the length of the cross section from 600 feet to <br />1, 500 feet. To further complicate the issue, based on the scale of the small map showing the gob <br />piles, at 200 feet/inch, cross-section B-B' is only 300 feet long (1-IY2 inches). Based on the 2:1 <br />slope indicator on the "Proposed Ground Surface" line for cross-section B-B', it appears as <br />though the correct horizontal scale should be 20 feet/inch. Please check the B-B' cross-section <br />line and detail and correct the scale as necessary. <br />The Division has no further concerns. In the submittal dated October 1, 2009, the scale on cross- <br />section B-B' of Figure 1 in Volume IX has been corrected. <br />16. Based on a review of Volume IX, Figure 1, Coal Mine Waste Disposal Area, the horizontal scale <br />of the inset cross-section C-Chas been changed and appears to be in error. The horizontal scale <br />on the currently approved figure is shown as 40 feet/inch. The horizontal scale on the revised <br />figure is shown as 100 feet/inch. This changes the length of the cross section from 800 feet to <br />2, 000 feet. To further complicate the issue, based on the scale of the small map showing the gob <br />piles, at 200 feet/inch, cross-section B-B' is only 400 feet long (2 inches). Based on the 2:1 slope <br />indicator on the "Proposed Ground Surface" line for cross-section C-C, it appears as though the <br />correct horizontal scale should be 20 feet/inch. Please check the C-Ccross-section line and <br />detail and correct the scale as necessary. <br />The Division has no further concerns. Figure 1 in Volume IX was revised accordingly in the <br />October 1, 2009 submittal. <br />16A. Based on BRL's responses in the October 1, 2009 submittal, the Division has calculated the <br />reclamation cost estimate for TR-64. The revised liability estimate for TR-64 is $93,93600 and <br />consists of a summary sheet, a task accounting for the additional 53,729 cubic yards of subsoil <br />4
