Since the .level of activity at the mine x111 stay the same, there is <br />no reason to expect any change in TSP concentrations. Specific mine site <br />monitoring x111 define mine site concentrations in more detail in the future. <br />2.6.7 METHODOLOGY <br />2.6.7.1 Existing Information <br />There are good information sources for both the regional and general <br />climate of the Edna Mine area. Perhaps the best information source of the <br />region is the Northwest Colorado Coal Environmental Impact Statement which <br />contains a more extensive description of the region's climate than is <br />included here. <br />• <br />2.6-9 <br />
