7. The application states on page 4.05-1 that hydrologic baseline <br />information has been and is being collected, compiled, and analyzed. The <br />application says that the origin of this data, along with a planned <br />monitoring program, is outlined in Section 2.04.7. Also, on page 4.05-3 <br />a reference is made to pH data reported in Section 2.04.7. No data or <br />proposed monitoring program has been included. <br />Reporting of this data is necessary to support the statement of probable <br />hydrologic consequences made in the application and for the Division's <br />required finding regarding cumulative hydrologic impacts in Hay Gulch. <br />The application should be revised to include all data previously <br />collected at the mine site on surface water baseline conditions and any <br />proposed monitoring program. <br />8. The application states on page 2.04-17 that the operations will not <br />impact any surface water users in Hay Gulch and that there is no need to <br />identify alternative water supplies for users in the area. This <br />conclusion may be valid, however, it is difficult to assess this <br />statement without the information required about the water users in the <br />area, as identified in Rule 2.04.7(4). The application should include a <br />map which provides this information. <br />9. A review of the National King Coal permit application indicates that a <br />spring ("Huntington Spring") is located approximately 400 feet west of <br />the proposed La Plata permit boundary. As this spring appears to be <br />located immediately down-gradient from the La Plata No. 1 Mine, the <br />applicant should verify if the spring exists. If the spring exists, it <br />should be determined if an application for water rights has been filed <br />for this spring. If the spring exists and the water has been <br />adjudicated, it is required to be protected from mining related impacts. <br />To determine whether mining will impact the spring, the applicant should <br />identify the unit (bedrock formation, colluvial material or alluvial <br />material) from which the spring flows. The baseline quantity and quality <br />of the spring also must be determined. The applicant should project what <br />impacts, if any, mining will have on this spring and how they will <br />monitor the spring to determine if impacts occur. A simple discharge and <br />water quality sampling program will be sufficient if ongoing monitoring <br />is necessary. <br />10. No discussion is made within this section about the source of water to be <br />used for the roads (page 4.03-1) and for dust suppression at the mine <br />face (page 2.05-17). Based on previous conversations with La Plata Coal, <br />the Division assumes water for these and any other activities at this <br />site will come from the water well in the gulch just west of the mine <br />facility area. Please provide a discussion about the source and legal <br />right to this water and depict the well on Map 6. <br />11. No discussion is provided for the leach field(s) proposed for this <br />site. Please provide a discussion pertaining to the leach field(s). <br />12. The climatological information on pages 2.04-TS(1) and 2.04-19(1) should <br />be updated to reflect the most current precipitation and temperature <br />data, respectively. This information is published by the Colorado State <br />Climatologist and is publicly available. <br />-4- <br />
