Interoffice Communication To From Date Subject File Dave Mahler January 14, 1983 SUPERFUND REPORTING Cconoco) At 3:55 p.m. on January 13, 1983 I reported a vinyl chloride release to the air to the National Response Center (800-424-8802). Ensign King accepted the report. After the usual formalities, I told him that we had a relief valve discharge of vinyl chloride from a reactor. The vinyl chloride dissipated in the air and did not get into the water. He asked if anyone was hurt, and I said no. I said that we estimate that 200 lbs. of vinyl chloride was dis charged. He asked what was done to stop the release, and I said that the plant operators noticed the release almost immediately and stopped the release. The release lasted for approximately 10 seconds. Weather conditions at the time of the release were: Barometric Pressure: Wind : Temperature Conditions : 30.01 in Hg South, 0 MPH 56 F ClearSkies At 8:30 a.m. on January 14, 1983 Ray Wilkerson from EPA in Atlanta called me for an explanation of the release. I told him that a reactor had been over filled with liquid and it overpressured through a relief valve to the atmos phere. The release appeared to have been caused by operator error, and only lasted for about 10 seconds. He asked if our plant was evacuated. I said that our plant's vinyl chloride monitoring system picked up a couple of high readings immediately after the release, but the vinyl chloride dissipated within a couple of minutes. There was one operator near the release who may have been overexposed to vinyl chloride. / ' fos.r *........h David L.
