-13- <br />keceiving Stream Standards <br />The Canadian River and its tributaries are classified by the Colorado Water <br />Quality Control Commission as "Bl", suitable for all raw water uses except <br />primary contact. The Water Quality Control Commission has deemed the <br />operation in compliance in light of NPUES Permit IVo. CU-0036854. IVo <br />violations of receiving stream standards have been reported nor identified by <br />the Division of Water kesources. <br />The Bourg 14ine will not impact the quality or quantity of ground water in the <br />3 wells within 3 miles of the permit area, since the yround water within the <br />mine site is hydrologically isolated from ground water tributary to these <br />wells. The Bourg Mine inay affect surface water rights through storage of <br />water within sediment ponds. The applicant states that the impact to senior <br />surface water rights will be minimal, since the flow of water in Idann Draw <br />contributes little to the flow of the Canadian River. The applicant also <br />states that water held in the sediment ponds would be available for <br />augmentation on call. The applicant has obtained an approved augmentation <br />plan for water stored in sediment ponds. <br />The operation is in compliance with the requirements of this section. <br />IX, Probable Hydroloyic Consequences of Mining and Cumulative Impacts <br />. ~..~.. n..i __ o nr r_ __., o rn c o _ <br />This assessment of probable hydrologic consequences and cumulative hydrologic <br />impacts study of the Bourg Mine has been prepared by the Colorado Mined Land <br />Reclamation Division (CMLRD). The cumulative hydrologic impacts study (CHIS) <br />was prepares pursuant to Rule 2.U7.6(2)(c). This CHIS assesses the probable <br />cumulative hydrologic impacts of all anticipated coal mining operations upon <br />the general area of the North Park Coal Field. Included in this assessment <br />are al] existing cos] mines and those proposed coal mines for which permit <br />applications have been submitted to the Division. <br />This study has been prepared using information and analyses contained in the <br />floury coal mine permit application, information and analyses contained in <br />other permit applications of mines located in the general area, and other <br />availaole information including site visitations by members of the Division's <br />staff. Coal mining operations in the study area include: <br />1. Walden Coal L'ompany -Bourg Strip Mine <br />2. Kerr Coal Company - Marr Strip <br />3. Wyoming Fuel Company - Canadian Strip <br />The life-of-mine areas of all of these coal mines are located within the <br />Canadian River watershed as shown on Figures 1 and 6. H11 mining operations <br />in the general area are open pit strip mines. <br />The coal seams to be mined, the total area of surface disturbance during the <br />5-year permit period and life-of-mine period for each operation are tabulated <br />in Table 1. <br />
