PATTON BOGGS, L.L.P. 550 M STREET, N.W. WASHINGTON, D.C. 20037-1350 (202) 457-6000 WRITER'S DIRECT DIAL (202) 457-5270 February 23, 1996 Hasmukh C. Shah, Ph.D. Manager, Vinyl Chloride Panel Chemical Manufacturers Association 1300 Wilson Boulevard Arlington, VA 22209 Re: Vinyl Chloride Risk Assessment Dear Has: Enclosed is a recent BNA article indicating that vinyl chloride is among 12 substances whose risk assessments will be updated on the Integrated Risk Information System (IRIS). According to the article, an upcoming notice will request health effects information on these substances. I did not know whether you were familiar with this activity, but clearly it will provide an opportunity to obtain needed changes in the "official" risk estimates for vinyl chloride. With best regards, Sincerely, Enclosure V\ , ,11 CMA115845
