Pacheco Slough, Concord, California | 1994-Jan-25

Initial Notification: MSO San Fransisco paged SSC at 1230 on January 26th to report a diesel and/or gasoline spill near Martinez, California. The spill occurred at 2130 on January 25th. The spill is reportedly from a ruptured pipeline that is running through a marsh adjacent to and west of Pacheco Slough (approximate position: 38 deg. 03 min. N/122 deg. 06 min. W). The slough runs south to north and empties into the Suisun Bay (pronounced "sah-soon") just east of the Carquinez Straits. The reported amount of product spilled has ranged from 3,000 to 10,000 gallons. It is also reported that there may be two separate spills concurrently impacting the area. Inital reports state that a vegetated area south of Waterfront Road, and north of a railroad line has been impacted by gasoline. Another vegetated area south of the railroad line has apparently been impacted by a Diesel Quality Reformate (Cutter Stock). The Executive Officer of MSO San Francisco, CDR Dan Ryan, conducted an overflight on the morning of the 26th. No oil was observed to have impacted Suisun Bay at that time. There is no reported Responsible Party at this time but cleanup crews from the nearby Tosco Refinery are responding. USCG district 11.
