Ms. Christine Johnston Mountain Coal Company Page S September 6, 1996 not available for sampling, please make note of this in text on page 16 and provide a revised report page. Please provide an explanation why these required data according to the approved monitoring plan were not collected. If these data are available provide them in revised report pages. 16. The approved water quality program effective in April 1995 following the approval of TR-71 requires that annual laboratory analyses for groundwater sites be conducted during the third sampling period. The following required analytical data are missing from the groundwater quality data presented in Appendix G: • Laboratory analyses were not conducted for the third sampling period for well GP-1. Fe, Mn, and TDS were the only laboratory data provided for GP-1, but these were provided for the second sampling period. • Laboratory analyses were not conducted for the third sampling period for well GB-1. Fe, Mn, and TDS were the only laboratory data provided for GB-1, but these were provided for the second sampling period. • No laboratory data were provided for well SW-3. It appears that there was less than one foot of water in the well on 09/14/95. For consistency please note that no sample could be obtained. Please provide an explanation why these required data according to the approved monitoring plan were not collected. If these data are available provide them in revised report pages. 17. The minimum baseline value shown for static water level elevation for well GP-1 is 6106.08 feet measured in September 1985 and the maximum value shown for May 1986 is 6182.56 feet. Given that the total depth of the well is only 58 feet how can the static water level increase to a height greater than the depth of the well? If these data are presented incorrectly, please provide a revised report page with the correct minimum and maximum baseline values.
