coal production during the permit term is projected to increase from the current projection <br />of 874,000 tons, to a maximum of 1,741,995 tons. Highwall miner extraction alone is <br />projected to account for a maximum annual production of up to 980,000 tons. To allow <br />for highwall mining, operational scheduling and baclifilling and grading timeftames within <br />the various mining blocks have been adjusted. Life of mine projections are that coal <br />extraction will continue through 2008, with mine pit bacl~illing and grading operations <br />completed in 2009, and reclamation grading of various ancillary facilities completed by <br />2010. Mine plan changes associated with PR-4 will result in an additional 17.5 acres of <br />surface disturbance immediately adjacent to previously approved disturbance areas, in the <br />southern portion of the south extension area. <br />In addition, various updates to the ownership and control information section of the permit <br />have been included in PR-4, refinements to the plans for design and certification of stock <br />tank impoundments have been addressed, and "As-Built" designs for Sediment Pond 17 <br />have been provided. <br />Seneca II-W Findings Document 3 November 17, 2(m4 <br />Permit Revision No. 4 <br />
