Narrative
On 4-23-18 at 08:00, operations personnel were attempting to complete an ldar repair on the block valve auxiliary blow down fitting on the body of the p/l 503 trap bypass valve. The ball check valve inside the fitting failed to seal/seat, resulting in a release of ethylene. The surrounding area was isolated and air monitoring initiated. Based on air monitoring two houses were evacuated. 911 was called and nrc was notified at approximately 08:55. The texas railroad commission pipeline safety division was also notified. The pipeline segment was isolated and water spray initiated on the release to keep emissions down. A flare was set up on the downstream valve site to reduce pressure and emissions on the line segment. Once pressure was reduced, repair personnel closed the valve and replaced the auxiliary blow down fitting with a valve and plug. The pipeline segment was restarted the next day at 10:30.
