The Delaware Department of Natural Resources and Environmental Control reported the release of more than 100 pounds of sulfur dioxide from the Delaware City Refinery of PBF Energy.
The release came through the flare system of the refinery. Equipment problems in the refining process often result in the releases. Delaware City handles a variety of crude oil types, including heavy crude that are more difficult to process.
DNREC said the incident is under investigation. Refinery problems have contributed to higher gas pries after the price at the pump dropped below $2 a gallon for a brief period.
