Polis, Governor | Dan Gibbs, Executive Director | Virginia Brannon, Director <br />1313 Sherman Street, Room 215 <br />Denver, CO 80203 <br /> <br /> Basil. Bear <br />Bowie Resources, LLC <br />P.O. Box 483 <br />Paonia, CO 81428 <br /> <br />April 22, 2019 <br /> <br />Re: Bowie No. 1 Mine, Permit No. C1981038, TR64 Adequacy concerns No. 4 <br /> <br />Dear Mr. Bear: <br /> <br />The Division has reviewed Bowie Resources, LLC (BRL) responses to the Division’s third adequacy <br />letter, dated, April 3, 2019. BRL’s responses were received on April 11, 2019. The remaining <br />adequacy s for TR-64 is based on the adequacy response from Stover & Associates, dated 11 <br />April 2019. <br /> <br />As requested by DRMS, Stover & Associates does not intend to include the nomograph (Figure <br />II-C-1) or the spreadsheet calculation for riprap size in the revised PAP. These should not be <br />included in the revised pages. <br /> <br />Stover & Associates provided a qualitative discussion to indicate that the reconstructed channel <br />will remain stable. The plan for the reconstructed East Roatcap Creek is in line with Rule <br />4.05.4(4), which address restoration of stream channels after diversion. Within this plan, the <br />channel and floodplain dimensions shall approximate the premining configuration and blend <br />with the undisturbed drainage above and below the reclaimed reach. <br /> <br />1. The TR-64 submittal (revised pages) should include additional information for <br />Volume 8 of the PAP. This information should include a description of the adjacent <br />reaches of channel, upstream and downstream of the channel reach to be restored. <br />This could entail a cover sheet and the report by McDermid Engineering Associates <br />(dated 9/10/1986), which was emailed by J. E. Stover and Associates to Rob Zuber of <br />CDRMS on 10 April 2019. <br /> <br />Please provide the additional information requested in item No. 1. If you need additional <br />clarification, please contact me at extension 8107, or Rob Zuber at extension 8113. <br /> <br />
