<br />1 1 . Acid or Toxic Formino Materials. There are no known acid or toxic forming <br />materials identified in this area. Since all of the materials planned for removal at <br />this site have been subjected to repeated cycles of reduction and oxidization <br />during the terms of geological time by the changing water table of the Yampa <br />River at this location, no concerns with these materials are anticipated. <br />12. Minimizing Disturbance to the Hydrologic Balance. Immediate disturbances to <br />the hydrological balance will be controlled by controlling the timing and quality <br />of waters collected in the dewatering trench. This trench will also act as a <br />treatment facility for surface waters which originate in the mine plan area. <br />Specifically, all surface waters from the denuded mining areas will be directed into <br />this trench priorto anyof these materials be discharged directly into the adjoining <br />waterways. Potential dust pollution of these areas will be controlled through the <br />frequency of dewatering and the use of dust suppressant chemicals such as <br />calcium chloride which will be applied as conditions require. <br />13. Processing. The only anticipated on-site processing will consist of crushing <br />and screening of the excavated gravel materials. The proposed location of the <br />crusher is within the proposed mine pit area as shown on Map 3, Tellier Gravel Pit - <br />Mine Plan Map. <br />All existing structures and adjacent property owners within 200 feet of the site are <br />shown on Map 2, Tellier Gravel Pit -Premining Conditions Map. This map also <br />shows the location of all existing disturbance within the proposed mine area. <br />Permit Boundary and Affected Area. The location of the permit boundary and <br />affected area are shown on Map 3, Tellier Gravel Pit -Mine Plan Map. <br />Owners. All of the lands within 200 feet of the affected area as shown on Map 2, <br />Tellier Gravel Pit -Premining Conditions Map. Luke jayand Caroline Tellier own the <br />surface and gravel minerals within the affected area. <br />Surface Features. The location of all surface features to be used in connection with <br />this proposed mining operation are shown on Map 2, Tellier Gravel Pit -Premining <br />Conditions Map and on Map 3, Tellier Gravel Pit -Mine Plan Map. <br />Direction of Mineral Extraction. The direction of mining as indicated by the yearly <br />mining blocks is shown on Map 3, Tellier Gravel Pit -Mine Plan Map. <br />Man-Made Structures. The location of all existing man-made features within two <br />hundred feet of this proposed mining operation are shown on Map 2, Tellier <br />Gravel Pit -Premining Conditions Map. Mining will be conducted within two <br />hundred feet of the existing property fence lines and the natural gas line as <br />described in the enclosed geotechnical report prepared by Northwest Colorado <br />8 <br />
