Narrative
At approximately 0740 ct on 07/30/2020, a 1" threaded connection on the inbound loutex meter skid at the beaumont terminal split, releasing approximately 6.6 gallons of natural gasoline. The line was shut down and release point was isolated. Investigation determined that bolted bracket supporting 1" thermal valve relief became disconnected. The lack of supporting structure caused thermal relief to break at the valve releasing product. This relief was replaced with a shorter run that does not require support to maintain its integrity.
