As you will recall, we discussed the general findings prior to my departure on that date. I reviewed the environmental dust evaluation program with Mr. Madlangbayan giving particular attention to questions that might arise concerning the techniques employed. I also commended him (and you) on the efficient manner with which both the analytical work and the reporting of results are accomplished. I believe we are defining the work environment about as well as can be expected. I discussed with you the program under consideration for meeting the new fiber limit (2 fibers/cc of air) that becomes effective July 1, 1976. This includes upgrading exhaust control systems in the two bagging areas, installation of a central vacuum system for better clean-up of floors, etc,, more effective use of sprinklers in control of dust from ore pile and 83?'Cseveral innovations in material handling to reduce dust loss./] UCC 013824
