The facilities provided will further reduce emission sources and provide for waste collection. A. Part 1 request was approved in February, 1977 for $600,000. A Part 2 request for $275,000 was approved in September, 1977. This Part 3 request will be followed by a final request in 1978 when the remaining scope is known. This request includes funds to start engineering, purchasing, and initial construction of items on the future request. The prelimary justification for this project is pollution abatement. 6.

Explanation end Economic Justification Problem No. 2028 Pw 2 of ^ Project No. B 2028 h quoit No. 3 This request for $330,000 will provide funds for the following: PVC 3o Install Sampling Devices on two PVC Emulsion Autoclave Discharge Lines. PVC 4 Provide an over pressure protection system for the VCL Gas Holder. PVC 5 Install piping to use the Hydrocarbon Flare Stack for a back-up for the PVC incinerator. PVC 7 Install Rupture Discs under Safety Valves in the PVC plant. PVC 9 VC1 Water Stripper for PVC Plant Waste Water. ECONOMICS _. . . ----- The facilities covered by this Part 3 request must be provided to comply with the EPA standard. Prior approval requests included funds for achieving compliance in the .vinyl chloride monomer, plant which is also covered by this standard. Fugitive VCM emissions will be reduced by this expenditure; material .cost savings are undefined but very small. --------------- ----- Justification is based on pollution abatement. ENVIRONMENTAL AND ENERGY IMPACT: There will be no energy impact resulting from this Part 3 request. Vinyl Chloride emissions to the atmosphere will be reduced an undetermined, amount (on the order of 122 M lb/yr), end HCl emissions will be increased (67M lbs./yr.) primarily as a result of burning VCl vent gas in-the Hydrocarbon area flare when the PVC incinerator is down for maintenance. Additional insignificant reductions in VCl discharged to the atmosphere and water will also be achieved. Capital Prorates to Divisions PD 100% 17.

F. Armstrong Address .From D. E. Park Subject VC1 Emission Reduction - EPA; Project B-2028-3 Address Date October 4, 1977 The attached project reguest represents the third of four requests for funds to implement programs to achieve compliance with the EPA VC1 Standard. This request covers the following items: PVC-3a Emulsion Autoclave Batch Sampling ft43 M) Provides automatic samplers, with controls, for stripped latex transfer headers for two spray dryer trains. This equipment is needed for sampling each batch of stripped latex, as required by the EPA Standard, without increasing the operator work load to the point that additional operators (one on roll) would be required. This part of the project had previously been estimated to cost $20 M. PVC-4 Gasholder Over-Under Pressure Protection ($28 M) Provides for high gasholder bell level instrumentation, including butterfly valves in each of two gasholder fill lines, to prevent overfilling the gasholder with a resultant blowing of the gasholder water seal. In a letter to the EPA dated September 21, 1977, we submitted a revised waiver request on this project asking for approval of a change of scope. The revised scope calls for automating the starting of the recovered monomer compressors on high gasholder level, which should minimize Instances, of gasholder seal blowing. If the change is approved by EPA, the money requested for PVC-4 will not be needed. The alternate scope is estimated to cost about $8,500 and will be done by PVC on a C. W. O. This part of the project had previously been estimated to cost $15 M. PVC-5 Flare Stack for Incinerator Backup ($167 M) Provides a four-inch transfer line plus necessary control instrumentation for transfer of VC1 vent gas from the PVC plant monomer recovery area to FC 2797 Page'5 of 5 the Hydrocarbon Area No. 3 flare stack. This line wouFd be used to transfer vent gas to the flare when the incinerator cannot handle the flow. Excessive flow rates occur when the incinerator Is down for maintenance or when the recovered monomer gas is heavily contaminated with air and/or nitrogen. In the event that Ethyl would be forced to incinerate VCl-containing streams that go to the flare stack, the new line would serve to transfer PVC plant vent gas to a new Hydrocarbon Area incinerator. This project was previously estimated by Engineering as a new flare stack at PVC and, based on a very preliminary scope, was expected to cost about $140 M. Later estimates by Technical Services indicated the PVC flare or a vent gas transfer line would cost about $200 M. PVC-7 Rupture Discs - VC1 Safety Valves ($27 M) Provides for Installing rupture discs below 31 safety valves in VC1 service at PVC, as required by the EPA Standard, to avoid VC1 emissions to the atmosphere. This project was previously estimated to cost $30 M. PVC-9 VC1 Water Stripper for PVC Plant Waste Water f$40 Ml Provides for the collection of PVC plant waste water, clarification to remove PVC solids, stripping to reduce the VC1 concentration to less than 5 ppm, and recovery of VC1. The $40 M requested is for the purchase of long-delivery equipment. D. E. Park Mr. E. W. Elmore Dr. M. F. Gautreaux Mr. R. Herzog Mr. M. M. Koenecke Mr. T. A. Leeper Mr. C. W, Montgomery Mr. R. D.
