Dept. of i~!aturat ~i~cources <br />Dear Mr. Savage: <br />Enclosed please find some of the information which you request- <br />ed at our March 30 meeting. These materials should answer, or clarify, <br />many of the questions discussed in your April 5 summary of that meet- <br />ing. The only information still lacking is that which requires fur- <br />ther study. We will forward additional material on water quality and <br />hydrologic impacts, operations description, backfilling and grading, <br />topsoil replacement depths, and roads as soon as it becomes available. <br />We are planning to wait until the end of the review process to submit <br />a worst case estimate for bonding purposes. <br />Flatiron Companies no longer has plans to use the Northgate load- <br />out for shipment of coal out of North Park. Because of this change <br />in plans, we would like to discontinue the permitting process for that <br />parcel of land. We will renew our efforts on this project, in the <br />future, if rail transportation from Walden becomes economically feas- <br />ible. <br />Scott Patten and I made an inspection of the "abandoned under- <br />ground mine" (Plate 17A) which is adjacent to the area we will be <br />mining. We determined, as a result of that inspection, that what <br />was previously called an abandoned mine is simply a small pit with <br />no former mine workings. The abandoned McCullum mine (Plate 1), <br />which is described in the archeological section of the permit ap- <br />plication, has already been mined through without any adverse safety <br />impacts. <br />With regard to the Bureau of Land Management haul road, I have <br />been unable to locate any reference to a 20 mph speed limit imposed <br />in our right-of-way lease. We feel that 30 mph as posted, is a safe <br />and reasonable speed limit for that road. <br />An inspection was made of the area you delineated for more in- <br />tensive soil sampling. It was determined, during that inspection, <br />that all of the topsoil scheduled to be removed from that area has <br />already been stockpiled. As a result of this finding, we obtained <br />samples from the topsoil stockpiles. The results of the analyses <br />
