,, <br />r <br /> <br />Mr. James T. Herron <br />Page Three <br />August 7, 1484 <br />These roads were constructed to the specifications <br />of Rule 4.03.3 and have been delineated on maps <br />supplied to the MLRD previously. The reseeding <br />efforts will be evaluated during the coming year. <br />Coal Pro- <br />cessing 1 The Colorado Geological Survey recommends that the <br />Seismic Stability Analysis be based on a Zone 2 <br />with a corresponding seismic coefficient of 0.10. <br />It should be noted that Colorado is located in <br />Seismic Zone 1. However, for purposes of Chen's <br />analysis, they analysed the stability on the <br />maximum embankment for steady state seepage con- <br />ditions, using a seismic coefficient of 0.16. The <br />value of 0.10 corresponds to Seismic Zone 3. <br />Reclama- <br />tion 2 Pages 4-67 through 9-74 addressed the post-mining <br />revegetation plan. <br />Attached is a copy of the changes made to the application. 69ith- <br />in the next week the Table of Contents will be updated to reflect <br />changes made in the application for completeness and adecuacy. <br />Storm King Mines appreciates your cooperation and our personnel <br />will be available to respond to any additional questions. <br />Sincerely, <br />-~ ~~ <br />Sam S.
