III IIIIIIIIIIIIIIII <br />STATE OF COLORADO <br />Roy Romer, Govei <br />DEPARTMENT OFNATURALRESOURCES <br />MINED LAND RECLAMATION DIVISION <br />FRED R. BANTA, Director <br />DATE: August 9, 1989 <br />T0: Cathy Begej <br />FROM: Matt Hayes ~~ ~ <br />RE: Bear Mine #3 B-seam Overburden Analyses: Response to Stipulation 26 <br />of Minor Revision 5 (MR-05). <br />Bear Coal Company has submitted the results of lab analyses for four <br />overburden samples. One sample each was taken from the B-seam floor coal and <br />the roof rock overlying the B-seam. This exceeds Bear Coal's committment <br />associated with t4inor Revision 6 to collect a single sample from Ramp 2. The <br />two samples taken from the temporary waste pile probably represent samples of <br />waste material from the driving of Ramp 4, though C-seam waste material is <br />also present as the base of this pile. The samples represent Bear Coal <br />Company's effort to comply with Stipulation 26 of 14inor Revision 5. The cover <br />letter to the revision called for two samples from the pile while the <br />stipulation itself called for samples of the B-seam floor coal and the roof <br />rock overlying the B-seam. Bear Coal tested each sample for all parameters <br />that were required by Stipulation 26. Thus Bear Coal has satisfactorily <br />complied with Stipulation 26 and the committment associated with Minor <br />Revision 6. <br />My preliminary review of the Bear Coal submitted revealed the following: <br />1. A CMLRD sample taken 3/2/89 was tested for the following parameters which <br />were not included in the Bear analyses. The Division did not require the <br />testing of any of these parameters. <br />Potassium <br />Cation Exchange Capacity <br />Exchangeable Sodium Percent <br />Ammonia as N <br />Chloride <br />Nitrogen, Total <br />Organic Matter <br />Phosphorus, Total <br />Carbonate, Total <br />+2 mm material <br />Aluminum <br />Barium <br />Chromium <br />Nickel <br />215 Centennial Building, 1313 Sherman Street Denver, Colorado 80203.2273 Tel.
