M._.....-- John: Attached find copies of reports etc., you requested. I hav-e no received the Bureau of Mines report yet. I will forward it when we receive it. As I reported, .and as you can Bee, the sampling was done under the best of conditions-bagging EG 100, no wind, etc. Kr. VanSandt's conclusion regarding the palletzer is wrong-we have always shown this area to be comparable to the bagger area. We are going to air-line respirators for the baggers and some kind of portable air-line unit for the palletizer operator. The latter presents a problem as nothing practicle is available at the present. White hat has one under devel opment. To confirm our discussion by phone: 1.^We feel a portable 'vacuum unit is necessary as soon as possible for Cleaning floors in the main bldg., shop, etc. This is to he added as item J-under 1. 2. We suggest addition to list of: ^(a) Vacune on Eedlers as well as screvjs. i/(b) Dust 'collection hood for Jeffrey Kill circuit. '(c) Improved collection from bins and top screws^ (d) Better way to clean 2M) dust collector. (e) Alarm for broken bags-dust collectors. (f) Revise or replace present ore feed front-end loader and hopper circuit to stop winnowed dust contamination of the shop area and mill buildings. As I mentioned, I requested 375,000 the "72" Budget but do not know the status of this. In assigning priorities to the items as you have listed them, I think that items 1, 7, and (f) above should have immediate action. One (l) and the effect of "f" upon it are items principly concerned with Dept, of Labor Emergency Standards for exposure to asbestos dust which became lav; upon 12-7-1971 when they were published in the Federal Register. continued............................ UCC 015382 J. A. Riddle -2- January 7t 1972 The other items result from the EPA proposed Emission Standards and I would think the immediate pressure here is not as great. In fact, some of the prooosals need both interpretation of meaning and generation ^information to be able to proceed. ' F. H. Larrison, Jr /clg UCC 015383
