ETHYL CORPORATION PETROLEUM CHEMICALS GROUP BATON ROUGE PLANT PLEASE ADDRESS REPLY TO; BOX 341 BATON ROUGE, LA, 70621 TO: Permanent Representatives of the Vinyl Chloride Safety Association The time for the next Vinyl Chloride Safety Association meeting is near. The attached agenda reflects the membership response to the questionnaire sent earlier and should provide a very interesting, informative and valuable meeting. You will note that there are three (3) slots on the program for presentation of an industry-wide response to questionnaires. These question naires are attached. Please complete as soon as possible and send to the address listed on the bottom of each questionnaire or bring the information to the New Orleans meeting. There is concern that all who plan to attend have not made reservations and may have difficulty making last minute arrangements. The meeting will be held in New Orleans, Louisiana, October 20 and 21 at the Marriott Hotel. You should plan to arrive Wednesday, October 19. Make reservations directly with the hotel. Write or call: New Orleans Marriott 555 Canal Street New Orleans, Louisiana 70140 (504) 581-1000 To reduce the early morning registration rush, a preregistration time will be available from 6:00 p.m. - 7:00 p.m., October 19, 1983. As permanent representative, please distribute copies of the agenda to all who plan to attend the meeting from your company. I look forward to seeing you in New Orleans. HG0:isd 9/7/83 H. G.
