Ms. Christine Johnston <br />Mountain Coal Company <br />Page 9 <br />August 23, 1996 <br />define the monitoring program and identify additional samples collected, if <br />any. <br />7. The Division acknowledges that sampling and analysis of nineteen additional <br />springs and one well was initiated in WY 1994. However, it needs to be <br />stated very clearly in text what was required for the 1994 Water Year <br />according to the approved monitoring program. Table 1.3-1 is not consistent <br />with what is described in text for spring sampling. Under Spring Water <br />Monitoring on page 4 it states that "twenty-six spring stations were sampled <br />throughout WY 1994" and Table 1.3-1 shows 23 springs sampled. Following <br />MR 102 (decision date 10/28/93) there were 9 springs in the required <br />monitoring program including: G-]2, G-14, G-]6, G-22, G-24, G-26B, G-la, <br />G-20, and CR-12. On page 4 under Spring Water Monitoring and on Table <br />1.3-1 please differentiate between required spring sampling stations and those <br />springs sampled as part of baseline data collection. Please submit revised <br />report pages. <br />8. The following analytical data are missing from the spring monitoring data in <br />Appendix F, Table F-1. <br />• Turbidity data is missing from the 04/18/94 sample for spring G-la. <br />• pH, specific conductance, and TSS data are missing for spring G-26B <br />for two of three required sampling rounds. <br />• Spring G-20 was only sampled once for WY 1994 instead of the three <br />required sample. <br />Please provide an explanation why these required data were not collected or <br />if they are available provide them in a revised report page. <br />9. On page 7 under Groundwater Monitoring, please add text to indicate that <br />well SOM-127-H was sealed and abandoned prior to WY 1994 or remove <br />reference to this well from the text. Also please add a statement that JMB-12 <br />was installed and sampled in addition to the required groundwater analyses <br />to collect baseline data for the Jumbo Mountain expansion. Please submit a <br />revised report page. <br />10. The Division commends incorporating the baseline minimum and maximum <br />values for spring water and groundwater with the analytical data presented for <br />
