You were copied on our letter dated January 28, <br />2002 documenting our inspection initiated by Mr. Leef's written complaint. <br />One of Mr. Leef's concerns was apparent dust in the river north and east of the coal loadout. <br />During our inspection, we did not observe dust directly in the river. However, a sprinkling of <br />black dust was apparent on rocks next to the river and in the pasture grass adjacent to the <br />riparian area. It appears likely that this dust originates from the coal loadout, particularly during <br />the loading of the coal shuttle train. It should be noted that on this day, winds were very strong <br />out of the west and occasional strong gusts were noted, causing dust production from exposed <br />dirt surfaces unrelated from coal mining. The coal loadout did not appear to be a significant <br />source of dust but loading operations were not occurring either. The mine operator confirmed <br />that the most significant dust production from the loadout area occurred during shuttle train <br />loading. - <br />We would like your assistance in determining how to proceed regarding determining what level <br />of dust in this area is acceptable. Please contact me at your convenience. <br />Thank you for your time. I look forward to hearing from you. <br />Since ely, <br />D~ <br />K Gorham <br />Environmental Protection Specialist II <br />CC: Elmer Bentley, Lorencito <br />Dan Hernandez, DMG <br />Ron Leef, landowner <br />
