The Delaware Department of Natural Resources and Environmental Control is reporting the ongoing release via of sulfur dioxide into the air at the Delaware City Refinery.
A leak in a boiler is resulting in the release of 500 pounds a day of sulfur dioxide, a byproduct of the refining process and a chemical that is considered a hazardous by the Environmental Protection Agency.
Disclosure of releases is available for those who sign up for the alerts from DNREC.
The releases have become less commonplace with new equipment and environmental standards. The refinery has reported reduced emissions each year.
Earlier this month, the release of more than 3,000 pounds of sulfur dioxide occurred during a boiler repair.
Individuals with questions can call the refinery at 302-834-6000.
