In this TR, I have <br />modified the section and maps to show a post mine land use change for the mine disturbed <br />portion of the Benson Property located north of the main ridgeline that runs west of the beginning <br />of the 26" HDPE pipeline. This TR modifies, at the landowner request, the Approximate <br />Original Contours reclamation approach in order to maximize farmable ground. Accordingly, the <br />land north of the main ridgeline will first slope at a more gentle grade than the AOC would <br />dictate, and then slope at a greater than AOC grade to meet the in-situ material. The steeper <br />than AOC slopes will use sediment control devices such as contour terraces. This modification <br />in reclamation terrain will create a larger area, suitable for modern sideroll irrigation, than <br />originally existed. <br />Please review this submission and let me know if you have any questions. <br />Sincerely, <br />Tony Adkins <br />Mine Engineer <br />F:\eng\data\wp\revisions\tr49. doc <br />
