This TR, entitled "Control Plan - Fugitive <br />Particulate Emissions: Climax Mine", describes past, <br />present, and future efforts to control wind blown <br />particulate emissions from the tailing ponds and dams at <br />the Climax Mine site at Fremont Pass. The plan discusses <br />best available, cost-effective, technology and has been <br />submitted to and approved by the Colorado Department of <br />Health, Air Pollution Control Division (APCD). A copy of <br />the ACPD approval letter is included. In addition to the <br />enclosed plan, AMAX intends to comply with the two <br />additions detailed by the APCD in its letter. <br />As was discussed in some detail during the recent hearings, <br />AMAX has been utilizing Coherex as its dust suppressant for <br />12 years with a high degree of success. Coherex has an <br />established, proven track record in the hard rock mining <br />industry, is readily available, and is cost efficient. The <br />material has been thoroughly researched and compared, with <br />similar materials on the market. Along this line, I have <br />enclosed a list of 25 literature references which discuss <br />the issue. Note that the highlighted references discuss <br />Coherex either alone or in comparative studies. <br />Further discussions of this plan can be incorporated in our <br />upcoming meetings relative to the entire Climax reclamation <br />program. Since these meetings may result in significant <br />
