The Delaware City Refinery could pay up to $20-thousand in fines for 6 tons of sulfur dioxide emissions two years ago and nearly 16 tons of other chemicals last year.
The Wilmington News Journal reports that state regulators decided to issue a single notice of violation for the two incidents.
The Delaware Natural Resources and Environmental Control will now figure out just how large the fines will be against PBF which owns the facility.
The company issued a statement reassuring residents that the facility is dedicated to being environmentally responsible and pledged to reduce emissions from the facility.
In the instance of the sulfur dioxide a leak was discovered in a 2 inch valve that caused the release and is a bi-product of its natural gas operation.
