Shelton <br />Director <br />August l8, 1981 <br />Mr. Leroy Black <br />UTE Engineering and Surveying Company <br />Box 674 <br />Delta, Colorado 81416 <br />Re: Grand Mesa Coal Company's Red Canyon Mine Permit Application <br />Our Pile No. C-034-81 <br />Dear Mr. Black: <br />Jim Pendleton has reviewed your preliminary responses to the Division's <br />subsidence' concerns for the Red Canyon No. 1 and No. 2 mines. The materials <br />submitted are acceptable, and assuming a number of additional tasks to <br />which Ute Engineering has committed are acceptably accomplished, the applicant <br />should satisfy the subsidence requirements. <br />Ute has committed to: ' <br />(1) Produce separate mine plan maps for both the D seam and the E seam workings. <br />(2) Prodvice a "subsidence monitoring map" which will show the monuments and <br />the safe areas beneath structures superimposed upon the mine plan map. <br />(3) Reinstall the subsidence monitoring monuments with a casing tube to <br />prevent freeze/thaw problems. <br />(4) Complete the photographic record of potentially effected structures. <br />The 180-day review period for both the Red Canyon mine and the Bear mine <br />expires on Rugust 78, 1981. It is apparent that, due to the complex nature <br />of the application review process, the final decision regarding permit approval <br />will be somewhat delayed in both cases. <br />This situation will not affect the status of the current permits under which <br />Bear and Grand Mesa are operating, as long as they continue to demonstrate a <br />desire to come into compliance with the permanent program. <br />If you have any questions, please give me a call. <br />Sincerely, _ <br />~ --' ~ <br />Dan Mathews <br />Reclamation Specialist <br />DM: mab <br />
