Certairfleed Date February 27, 1981 Subject i Transfer Procedure To C. A. Gellner From R. A. Bollich Location and mail code Location and mail code The following procedure is in operation at CertainTeed, Lake Charles when receiving monomer from P.P.G. Vinyl Plant, every transfer, with approximately one (1) hour wait between each storage tank transfer. Transfer Procedure 1. CertainTeed will notify the VCM plant control room that they desire a trans fer of VCM from the P.P.G. Vinyl Plant. Transfers will normally be made on the k - 12 and 12-8 shifts, but in the event monomer is needed on 8 - A shift, transfers will be made. 2. The sphere that is "CertainTeed Service" at P.P.G. plant site will be cir culated to obtain a uniform mixture and sampled. The analytical results will be used for all transfers made from the sphere until new material is added to the sphere. 3- The VCM Plant wi11 make proper valve alignment to put CertainTeed (day tank 3 or b) on line for transfer to CertainTeed. The following procedure must be done to insure proper packing of line: A. CertainTeed control room will notify the VCM Plant that a transfer is desired and give transfer number. B. VCM Plant transfer is then put in service with 3/^" cir culating line on pump open. ' C. With pump pressure holding between 100 to 120 PSIG, pack line keeping the CertainTeed block valve at, storage tank closed. D. After VCM line to storage tanks has been packed for 15 - 20 minutes, no less, and pressure charts prove that line has been packed at 100 to 120 PSIG, notify VCM plant operators to take levels, pressure and temperature readings on their tank. E. After readings are taken, the VCM Plant control room will notify CertainTeed control room that readings have been taken. F. The valve at CertainTeed1s2 end of the line will be opened by the CertainTeed operator and the transfer begyn.

Approximate amount recieved in one storage tank (10% - 80%) is 300,000 pounds. Note* as a secondary back-up to safety, stop transfer when digital numbered readout on VCM meter (control board) reaches 310,000 pounds. H. After amount is received into storage tank, CertainTeed will close the valve on our end of line. Approximately 10 minutes after valve is closed, CertainTeed will notify the VCM control room that the transfer is complete. I. At this time, P.P.G. Plant should take their ending gauge levels, pressures and temperature readings, notify Certain Teed control room that readings have been taken, then shut down their transfer pump. J. The utility operator will then return to storage tanks and check that all three automatic valves are closed, then close the manuel valve to the tank that is full (80%) and open the manuel valve to the other tank. (The Conoco and P.P.G. manuel*j valves should remain open). K. The utility operator will again check the system for leaks, check rupture disc, and call in the tank pressures to the con t ro1 room. Note* There should be at least one hour time lap before the next transfer. L. If transfer is going to slow, control room operator.should notify P.P.G. control room. P.P.G. can then make adjustments at their plant to speed up transfer. M. The official time on transfer is from 0700 to 0700 hours. pc Harry Hanks Bill Schwarzauer Bill Sonnier Norman Stine Shirley Galanti _ SL 0434 CONFIDENTIAL: Subject to Protective Order of 14th Judicial District Court No. 91-1145 SL 049012
