Mr. Jim Stover August 9, 1996 -New App./Bowie 2 Page 4 northwest/southeast which may bisect the proposed mine workings and provide possible means of communication with the Terror Creek drainage. It is possible that mining or mine dewatering could impact Tet7or Creek through groundwater communication. Please address this issue in detail. Impacts to Hubbard and Terror Creeks are also possible if and when B-seam mining occurs. Baseline and operational monitoring on Terror and Hubbard Creeks should be considered if B-seam mining is proposed. The BRL responses indicate that certain baseline monitoring plans were agreed during April of 1995. We have reviewed the letter of April 11, 1996, and we have a reasonable recollection of the meeting referenced in that letter. We do not recall, eliminating the possibility of ,nor does the letter preclude, baseline or operational monitoring of either Terror Creek or Hubbard Creek. Such monitoring may be required upon consideration of your responses. Such monitoring would include upstream and downstream quality and quantity measurements. We recall discussing the immediately available groundwater information, as well as discussing the possibility that other data might be necessary if impact projections or the quality of the existing data indicated such a need. We apologize if there has been some level of miscommunication. It is always our intention to communicate in good faith and as clearly as possible. 13a) A review of the baseline data provided in Exhibit 3 indicates the need to request additional information. i) Most of the baseline spring data indicate that measurements began in June 1995 and ended in December 1995. Some measurements began later in the year. We recommended that data measurements begin in April, in order to characterize the full hydrological cycle, since the April and May periods tend to show highest flows. Please provide data for all springs beginning in April 1995, or 1996, and for each month thereafter where data are currently missing. Please provide a plan to remedy this situation. ii) The application indicates that pond observations began in September 1995. Please provide recent (1995 or 1996) data which indicate the full hydrological cycle. We acknowledge the presence of the 1984 data, but more current information is recommended for these important surface features. iii) Please provide the flow rate data for the Deer Trail Ditch (lower) for June 14, 1996, and, for the Deer Trail Ditch (upper) for May 11, 1996 and June 14, 1996.
