Armstrong h ro m John Riopelle Asbestos Levels Cl iveland. T e n n esse e Please refe r to your 3/4/74 le tte r on the above subject. Re garding the 17.1 average asbestos fib e r level on block briquette press 15-7 i t is important to note that the tests producing th is re su lt were made immediately upon completion of the in s ta lla tio n of the exhaust v e n tila tio n system on th is press. As you know, th is is the press upon which we delayed in s ta lla tio n of the exhaust ven tilatio n system fo r business reasons. Thus, we believe the high fib e r level resulted more from the need to make the usual adjustments to a new in s ta lla tio n than from the actual ca p a b ility of the system. In support o f th is b e lie f th is press now has a 5.7 average asbestos fib e r le v e l, based on tests made on 2/28/74 - a month a fte r the in s ta lla tio n of the exhaust^ventilation system. In sta lla tio n of the automatic mix feed systemshould further reduce the fib e r level to some value below the current 5.0 sp e cifica tio n . Your le t te r also states that the reclaim room had 5 samples exceeding 10 fib e rs . Here i t is important to note that these values were based upon te sts made on reclaim chopper 19-3 and 19-4 before moving th is equipment into thp reclaim room. As you know, th is move was made during our Christmas1973 shut down. The equipment w ill operate in a closed room and be loaded from outside the room v ia .a conveyor system. Referring to the chart attached to your 3/4/74 le t te r we note a 6.2 fib e r level on the block external grinder from the January, 1974 sampling. This is an error - the correct value is 1.6.
