## Summary

The facility had a release incident on 04/10/2020, when an operator did not properly implement the site's Safety System Bypass Procedure.  When attempting to reseat a pressure safety valve (PSV). Instead of closing the upstream high-pressure valve to relieve pressure on the PSV, the downstream low-pressure valve was closed, resulting in an overpressure and subsequent release of high-pressure hydrocarbon from the
downstream valve bonnet. Failure to follow the Safety System Bypass Procedure is a violation of 40 CFR 68.69(a), Operating Procedures.
