At the time of the complaint regarding very strong odor coming from Murphy Oil Refinery as well as a large flame and rumbling noise, there was a mild waste water odor from the waste water treatment plant noticeable at Gate 8. This odor was not described as a gasoline odor. The plant did receive a call from the community fro a gasoline odor which was not found during the investigation of the call which included a drive through the adjacent neighborhood. The plant was in normal operation except for the distillate hydro treater which was in the process of restarting after a mechanical upset on the previous day. The plant also received a call for vibration that was investigated. The compressor at the distillate hydro treater (B-^) was in restart mode. There was some vibration associated with the compressor restart. No noise problems were noted in the plant record.
