The July 17, 2001 explosion at the Delaware City Refinery killed 1 worker, injured eight others, and sent thousands of gallons of toxic chemicals into the Delaware River, went unrecognized by the Refinery at the CAP (Citizens Advisory Panel), held on the 11-year anniversary.  A 2002 report by the U.S. Chemical Safety and Hazard Investigation Board found that the explosion was caused by chronic neglect on the part of the refinery's owners and managers.  Dangerous working conditions have continued at the refinery, leading to additional fatalities.  Two workers were killed by nitrogen asphyxiation on November 5, 2005.
