-4- In order for the Division to approve the surface water monitoring plan described in the initial application on pages 780-109aaa and bbb, additional clarification was required. The following stipulation was necessary for permit approval and the requirement to submit an annual hydrologic report remains in place. Therefore, the original stipulation has been modified to the following: Stipulation No. R1 THE PERMITTEE IS REQUIRED TO SUBMIT TO THE DIVISION A YEARLY REPORT ON THE PROGRESS OF HYDROLOGIC MONITORING WHICH INCLUDES ALL DATA COLLECTED FOR THAT YEAR AND A DISCUSSION ON ANY CONCLUSIONS WHICH CAN BE DRAWN FROM THE DATA. The data submitted in Table 10 of the original permit application did not support the conclusion that coal dust does not affect water quality in the swamp adjacent to the tipple. In order to clarify this issue, the following stipulation was necessary: The applicant should re-analyze and resubmit the existing data in Table 10 to consider the effects of coal dust on water quality in the adjacent swamp, or alternatively the applicant should redesign the water monitoring program at the tipple to collect usable data. This information should be submitted to the Division no later than April 1, 1981. This stipulation has been resolved. Hydrologic data submitted during the previous permit term indicates that no significant effects to the surface water hydrologic system have been detected. This is primarily due to the reduction in coal production from previously anticipated levels. This section is in compliance with all applicable requirements, with continued acceptance of the stipulations. VI. Hydrologic Balance: Ground Water (2.04.5, 2.04.7, 2.,05.3(4) Kerr Coal Company, in the original permit application, presented data concerning the ground water hydrology of the mine area. As part of the baseline hydrologic investigation, aquifer tests were performed on the Sudduth Coal seam and its underburden. Aquifer testing of the overburden was performed reported by Warren Hoffstra in a USGS Open File Report entitled "Hydrology of the McCallum Study Area". The Sudduth Coal seam had two pumping tests run, one on a faulted area near Bush Draw and another on an unfaulted area. The permeability of the faulted area was calculated to range between 16.5 gpd/f t2 and 25.4 gpd/f t2 to 4.0 gpd /f t2. This permeability is sufficient to transmit and store water for limited beneficial use, and can be expected to yield from 10 to 40 gallons per minute.
