Box 518 <br />Somerset, Colorado 81434 <br />RE: B-Seam Uverburoen Analyses: Satisfaction of Stipulation 26 attacneo to <br />Minor Revision 5 (NR-05) and Commitment from Minor Revision 6 (MR-Do'); <br />Bear Mine #3, C-81-03s. <br />Dear Mr. Springer: <br />Tne Division has reviewed your submittal dated July 29, 1989 (receives at our <br />offices on August 2, 1989) which was in response to both Stipulation 26 of <br />Minor Revision 5 and a commitment associates with Minor Revision 6. <br />Stipulation 26 required two geotechnical samples be taken from material <br />excavates for Ramp 4 construction. Ramp 4 connects the C seam and the new B <br />seam workings. A commitment associated with Minor Revision #6 required one <br />sample to be collected from material from Ramp 2 which was also developed from <br />the C seam to the 8 seam. Bear Coal Company has complied with the <br />requirements of Stipulation 26 and exceeaed the requirements of the Minor <br />Revision 6 commitment. <br />Sample results have been reviewed. The results confirmed the conclusions that <br />the Division reached through analysis of an earlier sample taken during the <br />l+larcn 2, 1989 CMLRD inspection. These conclusions were included in the <br />coirment section of the June Z7, 1989 CMLRD mine site inspection report. <br />Permanent disposal of development waste in the present temporary pile will <br />require 4 feet of nontoxic cover because of high sodium and SAR values (44.0, <br />7.1, 27.2, 31.1, 33.9). These values, with one exception, exceed the SAR <br />standard of 12 which has been proposed b.y the Montana Department of State <br />Lanus ana the Wyoming Department of Environmental Quality. <br />if you have any questions, please ao not hesitate to contact me. <br />Sincerely, <br />1Aattnew S.
