R0 EASE REPORTABLE VCM SPI1 1 - LOUISVILLE LPA ft* *tttt*#** ******-********* KM H HR Qu 2/19/93 at 1:A5 PM, a calculated 8.A lbs. of VCM was eleased when the equipment recovery line failed under the VCM vapor i ecoveiy Miters. A cal] was placed to 911. Prompt response by area personnel minimized the loss. On 2/22/73 at 10:00 AM a Board of Review was held in the I PA Confeience Roam with the following in attendance: H.

He beaan to smell an odor. He quickly notified Mike Warfield, Production Super visoi . Mike applied water to the leak using a hose, requested Hie equipment he placed tin recovery and instructed to sound the the alarm. REDACTED NGC 13643 Reportable VCM Spill - 1 PA Page 2 A call Has placed to 911 at 1:55 PH. After area monitorinq assured a safe condition, the all clear Has given. Based upon area monitor readings and measured volumes, the release was calculated to be 8.4 lbs. of VCM. Facts Surroundinq the Incident: [. lire equiproeot recovery (reader was nut in use at the time n! tire i u< itlenl. 2. lhe failed line was 17 year old stherlule 40 carbon steel. 3. Liquid VCM was present in the r ei over y header. Management Systems Investigation: 1. lhe involved corrosion was inside out in rrature. 2. The failure was chemical pitting ttti the bottom surface only. 3. lhe failure was not freeze related. 4. The source of the liquid VCM was a failed equipment recovery valve seal' at FIL-5F VCM charge filter. 5. lhe value was locked in the closed position. 6. lire seat failure resulted from heal. Conclusion: lhe line failure was the result nf extensive chemical pitting aqqielated by undetected VCM liquid pressure. 5. E. Hale General Foreman - LPA NGC 13644
