UPDATING: DNREC Monitoring and Investigating Excess Pollution Emissions Caused by Delaware City Refinery Outage

Department of Natural Resources and Environmental Control | Division of Air Quality | News | Date Posted: Thursday, July 21, 2022



An outage early this morning at the Delaware City Refining Company that resulted in excess emissions of pollutants was resolved by midday when the refinery’s carbon monoxide boiler on the fluid coking unit was brought back online, the Department of Natural Resources and Environmental Control announced this afternoon. The outage resulted in unpermitted emissions of carbon monoxide (CO), sulfur dioxide, hydrogen sulfide, ammonia, hydrogen cyanide and particulate matter.

The DNREC Division of Air Quality continued to assess and monitor the situation at the refinery after the CO boiler came back online. DNREC’s monitoring station near Delaware City did not show elevated levels of particulate matter resulting from the CO boiler outage, and DNREC does not expect the excess emissions to impact public health and safety.

DNREC is investigating the refinery’s unpermitted release of pollutants and will take appropriate follow-up action, to include enforcement if warranted.
