Product bulletins and <br />MSDS sheets for Enact 7885 are enclosed. <br />Wyoming Fuel Company is proposing a field trial of this dual <br />treatment program to determine the actual potential for <br />further reducing TSS concentration levels. One portafeed <br />container of 7885 will be ordered for this trial. This will <br />provide enough chemical for a 30 day test. NALCO will <br />provide onsite assistance in setting up and optimizing the <br />dual treatment program. <br />If the field trial is successful in reducing TSS levels, a <br />continuing program of dual chemical treatment will be <br />initiated on an as needed basis. Portable bulk tanks will <br />be located adjacent to the main return fan house and pond <br />002. The locations of these portable tanks is shown on the <br />enclosed Golden Eagle Surface Facilities map. The area is <br />already disturbed and no permanent facilities will be <br />constructed. Thus no bond increase will be required. <br />A copy of the letter from the Colorado Health Department <br />approving the thirty day field trial for dual chemical <br />treatment of our mine water is also enclosed. <br />If you need further information or have any questions on <br />this matter please feel free to contact me. <br />Sincerely, <br />Ronald G.
