Martin COMPANY Bldg. 2000-4418 location TECHNICAL CENTER Dr. A. B. Steele 28th Floor NEW YORK OFFICE p. box 471, texas city, texas 77590 date October 31, 1974 subject The list below covers, as well as we can anticipate at this time, the needs of the Texas City Plant as it attempts to lower employee exposure to VCM. There is absolutely no guarantee that if these projects are implemented in the production units that a 1 PPM 8-hour TWA maximum will be realized. At this time in the Suspension/Non-Solvent area based on data from the area VFA monitors, the average 8-hour TWA is 5-7 PPM and in solvent it is 3-6 PPM. As you know the tank car unloading facilities are shared by both P.C. 282 and 381. Have not attempted to place dollar amount on General Facilities since your guess will be as good as mine in terms of capital and increased operating cost. Also suggest adding another $500 M for Distribution area projects for ventilating bagging rooms, hopper cars, van boxes, waste collection, dust collection, etc. If the Standard finally is promulgated at 1 PPM TWA, then probably anything we put down here is conservative. Remember we have had very little time to analyze the problem and develop solutions. We have only had an instrument at Texas City that would detect leaks and that was truly portable for one month. The study is premature but faced with the necessity of evolving some sort of plan, here it is. Vinyl Chloride Unloading Facilities 1. Vinyl chloride vapor reheater to improve tank car unloading capability Cost - M$ 50 2. Purging facilities for recovering VCM when removing tank cars for maintenance 150 3. Install pipe line to Oyster Creek (40 miles) plus storage sphere at Texas City Suspension/Non-Solvent Area V 1. Improved vacuum stripping of resin slurry - 700 2. Improved monomer recovery system including gas holder and MEK absorber for vents 1,500 3. Prover tanks for improving reliability of process 1,000 UCC 090940 Mr. R. W. Martin and Dr. A. B. Steele --22-- October 31, 1974 Cost - M$ 4. Miscellaneous installation of mechanical seals in pumps, new valves, improved ventilation systems, etc. 500 5. Additional area VCM analyzers and data logging equipment 100 6. Contingencies 500 Total 3,400 Solvent Resins Area 1. Autoclave mechanical seals, Dynatrols 350 2. Retray existing stripping stills 100 3. Additional area VCM analyzers and data logging equipment 100 4. Route existing vents to flare 100 5. Purchase new pumps, install mechanical seals on existing pumps, new valves, etc. 500 6. Vent collection system and compressor for losses such as autoclave sampling, compressor packing leaks, sample analysis vent hoods, etc. 200 May need a new distillation column to separate VCM from recovered acetone - General Facilities 1. Increased Industrial Hygiene personnel and facilities. 2. New lunch and locker rooms for support groups .such as maintenance personnel. 3. Increased medical personnel and outside expenses for examinations. 4. Increased record keeping personnel, storage area for records, and computerized data logging. 5. Solid waste disposal facilities such as an incinerator to prevent having to make other sections of plant a regulated area. M. E. Eisenhour UCC 090941
