Appendix 14-5 <br />u <br />IN REPLY REFER TO: <br />3400 (CO-130) <br />Dan Mathews <br />Divsion of Minerals and Geology <br />2148 Broadway, #CS <br />Grand Junction, Colorado 81503 <br />NOV 16 2000 <br />Re: Powderhom Coal Company, Permit C-81-041, Revision Order TR-32 <br />Dear Mr. Mathews: <br />TAI~~ ~ <br />PRIDEIN~ <br />~ ~ <br />^ <br />This office has reviewed the referenced technical revision. Part of the revision addresses the <br />retention of three culvert crossings along the Coal Canyon Road (Haul Road 4) and drainage <br />reconstruction work for Coal Creek. The culvert crossings include: <br />• Crossing number 1 (lower crossing) -two 81" x 59" culverts <br />Crossing number 2 (middle crossing) -dip section with six 36" culverts <br />Crossing number 3 (upper crossing) - 72" culvert <br />By letter dated June 27, 2000, this office requested that the culverts be left in-place to better <br />facilitate administrative and public access. Since that time, BLM, DMG, and Stover & <br />Associates have met in order to discuss the details of the planned work. The Stover letter dated <br />November 10, 2000, adequately addressed BLM's remaining concern for the wingwall <br />estrangement on the culvert dip section. <br />Based on our review, we recommend approval of the technical revision. The BLM agrees to <br />assume responsibility for future maintenance ofthe culverts upon completion of the drainage <br />reconstruction and culvert work and upon approval of final bond release, or permit/bond <br />revocation, for that portion of Haul Road 4 extending from the lower culvert crossing to the <br />upper culvert crossing. If you have any questions on this matter, please contact Bruce Fowler <br />(244-3036)orJim Scheidt(244-3075). <br />Sincerely, <br />~~ ~~ G~,,,.__ <br />.
