r <br />Ms. Christine Johnston <br />Mountain Coal Company <br />Page 2 <br />December 11, 1997 <br />4. A permit commitment which reyuires submittal of laboratory analytical data sheets and <br />chain-of-custody forms will not be required at this time. However, such documentation <br />may be required in the future if monitoring and reporting omissions and/or inconsistencis <br />in data reporting are identified. <br />5. No response required. <br />6. Please revise the hydrologic monitoring and reporting section of the permit to include <br />anion and cation balances with all future AHR reported analyses for surface water. This <br />practice was recommended during a previous Office of Surface Mining oversight <br />inspection. The recommendation has merit and would serve to provide a quality <br />assurance/quality control check on laboratory data. <br />7. No response required. <br />If you have any questions please call me. <br />Sincerely, <br />B~. <br />Michael P. Boulay <br />Environmental Protection Specialist <br />
