We got some calls this morning from a few neighbors who heard a swooshing sound in the 6:00 hour.  We heard the noise as well and did an immediate and thorough investigation all around the refinery, including a check of pressure relief valves and our monitoring equipment.  Operations are normal, and we do not have any indication the noise came from Shell. 

Thanks to those who called.  Please feel free to call our environmental hotline at (925) 313-3777 whenever you have a question, comment, or suggestion.  Our 24-hour response staff will always get right on it.
