Rule 2.04.7(3) - Alternate Water supply Information <br />The information contained in the permit application demonstrates that <br />strip pits will be dry, since water bearing strata will not be <br />intercepted by the pits. The driller's lithologic log of drill hole <br />29-8, located adjacent to the 30" air shaft, states water was encountered <br />at a depth of 43 feet whereas the coal to be mined ranged from 9 to <br />19 feet. <br />The water table in hole 29-4, the monitor well located just outside the <br />pit area at the southwest corner, shows water was standing in the drill <br />hole over a year's time period at depths ranging from 83 to 89 feet. <br />Water was encountered during drilling at 83 feet. The coal to be mined <br />is 57 to 67 feet deep. <br />Water samples of this water and two other wells were analyzed for <br />temperature, pH, depth, and conductivity on a monthly basis for one year <br />to Drovide a baseline study of ground water properties Drior to strip <br />mining to determine the effects that mining may have on the water. <br />There will be no contamination, diminution or interruption of surface <br />water sources as a result of the operation. There is one ephemeral <br />drainage which will receive runoff from the disturbed area, but all <br />runoff will be routed through an approved sediment control system and <br />will meet applicable effluent requirements. The Division's conclusions <br />regarding surface and ground water impacts of the mine derived from data <br />included in the application are contained in the findings document and <br />reaffirm that this operation will not cause diminution, contamination, or <br />interruption. <br />Rule 2.04.0(sc) - Climatological Information <br />The Division does not understand the question or concern. Exhibit G <br />shows an annual surface wind summary derived from information collected <br />from October 1938-1943. Pages 2 and 3 show summaries of climatic data <br />for Trinidad, Colorado for years 1954-1980. The operator supplied the <br />5 years of wind summary to show the Division the direction of winds in <br />the area. The information provided is adequate to satisfy the <br />requirements of the Act and Rules. <br />Rule 2.04.10 - Vegetation Information <br />Map 5, Vegetation, has been revised to show that 18 transects were taken <br />r rather than the 15 shown. The new map is located in the Map 5 slot <br />located in Volume II. Related to the vegetation information is <br />additional information contained Exhibit H, Volume III. Exhibit H (d) <br />replaced the same in the report, and Exhibits (h), (i), and (j) were <br />added. This maD was replaced in the application copy on file at the <br />Las Animas County Courthouse on October 5, 1990. <br />-5- <br />
