Box 773987 <br />Steamboat Springs, Colorado 81639 <br />Re: Stipulations Response - Updating of Grassy Gap Permit Application Sid io <br />Dear Mr. Sherman: <br />The Division has reviewed the permit updates as submitted by Mr. Tommy Raye on <br />February 19, 1985. This review was done by Dan Mathews and myself. We <br />appreciate Rockcastle's timely submittal of this information. <br />The following are several inadequacies or problems noted with the updates: <br />1. The April 21, 1984 overburden analyses and correspondence regarding <br />sampling procedures should be included. <br />2. Three copies of the alluvial valley floor (AVF) maps should be sent to <br />the Division. <br />3. Three copies of an updated hydrology sampling map should be submitted <br />showing the required surface, alluvial, and groundwater monitoring <br />sites. <br />4. Table 5, page III-29 and Table 3, page IV-6 have contradictory depth of <br />topsoils for the 34E,F soil type. This discrepancy should be resolved. <br />I will be pleased to discuss any of these issues should you have a question. <br />Sincerely, <br />Candace M. Thompson <br />Hydrologist <br />CMT/fw <br />cc: Mark Korb <br />Doc. No. 0821 <br />423 Centennial Building, 1313 Sherman Street Denver, Colorado 80203 Tel. (303) 866-356! <br />
