ABD00309594 Vinyl. - J. D. Olson, V. S. Carroll Safety The Vinyl Department had no injuries in December. The monthly safety meetings were held on shift. General 1. December production was 43.5 MM pounds. This is an Aberdeen Plant resin production record surpassing the old record of 42.6 MM pounds set in November, 1990. 2. Railcar empty hoppers were in short supply near the end of December. This has resulted in significant reactor downtime in early January.

Truitt The relief valves and rupture discs on reactor 600 were changed out for low mole resin production. Reactors 400 and 700 seals failed and were rebuilt for spares. Reactor 400 seal failed due to line pluggage, and reactor 700 seal failed due to overpressurization. m The #1 Bird centrifuge was reinstalled. The Bird had been sent out for refurbishing after several months in service. The north fluid bed Bird gearbox was changed out due to a seal leak. Two major valves were changed out of the Vinyl unit. Two power supplies were replaced in the Vinyl control room after they were found to be faulty. The Gaitronics units in the Old and New Units were repaired to enhance communications. The test run on the propane system was conducted in preparation for winter alert. The valves on #8 and #9 air compressors were repaired. The west bio-disc bearing on the north end was replaced due to wear.
