On 12/2/11 at 7:40 pm a resident of Norco, LA phoned the Motiva Norco Site Supervisor and communicated that a strong odor was coming from the site into the community. An immediate investigation by onsite personnel determined that the odor was from Motiva's Coker Unit. While depressuring the coke drum, PV-917, sour water in the vent knockout drum, PV-134, was pressured out into the atmosphere causing a strong odor. The refinery claims the odor dissipated by 9:00 pm. A follow-up call was made to the resident describing what was found. The resident stated that the smell was gone.
No Information Given.

Further investigation shows there was a release. Weather at the time of the incident was 58 degrees and clear. The winds were out of the East/Northeast at 3mph.
