BANTA, Director <br />May 19, 1989 <br />Mr. Rick Hughes <br />Colorado Yampa Coal Company <br />29587 Routt County Road No. 27 <br />Oak Creek, Colorado 80467 <br />Re: Technical Revision 23, Hydrologic Features/Small Area Exemptions, File <br />No. C-81-071 <br />Dear Mr. Hughes: <br />On May 16, 1989, we received your response to our adequacy letter of <br />April 4, 1984. Some additional issues must be resolved prior to our issuance <br />of an approval decision. The decision deadline had been continued to <br />May 12, 1989; therefore, we recommend that an additional continuance should be <br />requested to avoid a denial notice. <br />The following issues must be resolved: <br />We requested that Map 9A be revised to include the entire permit <br />and drainage area for the southwest portion of the mine. It was <br />our hope that the mapped area could be shifted to the north about <br />2 inches to allow the required incorporation. The southwest area <br />is relatively small and it seems that accurate topographic <br />information should be available for the area, given the fact that <br />topographic information is available for all adjacent areas to the <br />north, west and east. This is verified by the topographic maps <br />submitted as supplements 1 and 2. <br />The purpose of this technical revision was to provide a single <br />concise map which shows all required hydrologic features. The <br />submitted maps 9A and l0A are excellent except for the omission of <br />the southwest area. It is understood that it will be necessary for <br />your draftsman to apply additional and valuable time, perhaps along <br />with some editing of existing map sheets. However, the added work <br />should result in a product that both satisfies the legal <br />requirements and satisfies the original purpose of the technical <br />revision. Please revise maps 9A and 1DA to incorporate the <br />southwest area. <br />15 Centennial Building, 1313 Sherman Street Denver, Colorado 80203.2273 Tel. (303) 866-3567 <br />
