,, <br /> <br />Mr. Darcy Ferguson -7- February 18, 1993 <br />any structures (roads, ponds, out-of-pit fill) within the <br />permit area per Rules 2.04.6(1)(a), (b), and (c). Please <br />provide any drilling information available from the <br />installation of the Pueblo Coal well (PC-1), such as <br />driller's logs, pump tests, or completion diagrams. Please <br />identify in which formation(s) is it completed. <br />Groundwater• <br />The groundwater description in Section 2.04.7 suggests that <br />there is an aquifer from the top of the Shamrock coal to the <br />base of the Carbonera. This may be an oversimplification of <br />the driller's log for 82-5. Review the lithology where <br />water was observed and correlate it with the water producing <br />zones in Hole lOB. Then reword your description to respond <br />to Rule 2.04.7(1)(a)(ii), which asks for the aquifers to be <br />lithologically characterized. <br />2. Please provide any water level and water quality data on <br />Well 82-5 through four quarters of a year, per Rule <br />2.04.7(1)(a)(iii). <br />3. Please remove the reference to the Peerless Coal Gulch Mine <br />from the permit application narrative. As a general rule of <br />thumb, the permit application should serve as a source of <br />information about the mine area for the site being permitted <br />and the surrounding general area. Inclusion of other mines' <br />resources is unnecessary and could be misleading. <br />Mitigation of Hydrologic Impacts: <br />1. Please identify the location of well 82-6 to be added to the <br />hydrologic monitoring plan per the response on page 4 of the <br />adequacy comments and referenced on page 4-13. <br />a. Please provide a driller's log of this well and <br />completion information; <br />b. Provide any monitoring data which has. been acquired <br />from this hole. <br />2. Information in Section 2.04.7 suggests that 82-6 is a <br />typographical error and that the well is actually 82-5. If <br />this is so, please disregard these two questions, but <br />correct the permit application. Page 5.35 indicates that a <br />well 82-3 will be monitored. The permit application no <br />evidence of a well with that designation. <br />
