Ms. Christine Johnston <br />Mountain Coal Company <br />Page 3 <br />August 23, 1996 <br />situation can be more rapidly mitigated in the future, to avoid data loss. <br />Please clarify and provide a revised report page. <br />3. The report does not indicate what laboratory was used for sample analysis, <br />nor does the report provide the laboratory analytical data (other than <br />compiled in report tables). Please provide the name of the laboratory used <br />and indicate where the actual laboratory data are filed in a revised report <br />page. <br />4. Footnote 3 is missing from page 4, please provide this in a revised report <br />page. <br />5. In Appendix D (Surface Water Quality Monitoring Data), the following <br />analytical results were not provided: <br />• Mn results are not provided for the 6/07/93 sample. <br />• pH, specific conductance, and TSS results are not provided for <br />the North Fork Upper location for 04/26/93, 06/07/93, and <br />09/07/93 samples. <br />• pH, specific conductance, and TSS results are not provided for <br />the North Fork Lower location for 04/26/93, 06/07/93, and <br />09/07/93 samples. <br />Please provide revised report pages which include the above data. <br />6. Baseline data for average flow (North Fork Upper and North Fork Lower <br />locations) are not provided in Table E-1. This is critical data for assessing <br />impacts to water quantity. If these data are available please provide a revised <br />Table E-1. <br />7. In Appendix F, spring G-12 has a pH value of 6.8 listed for the 04/28/93 <br />sample date. The 04/28/93 date was listed as no flow. Likewise, spring G-20 <br />is listed as no flow; however, pH and specific conductance values are listed. <br />Please explain and/or correct these entries. <br />8. On Table E-2, change spring G-1 to G-la for consistency. Spring G-12 has <br />a pH value listed for a no flow condition. Spring G-20 has a pH and specific <br />
