The release by refinery owned by PBF Energy was reported at 9:45 p.m. No estimate of the amount of sulfer dioxide released was available, DNREC announced through its notification system. The release is ongoing, DNREC stated.
It was the third such release in the past week or so at the refinery.
The other two releases were caused by compressor problems.
Such releases are closely watched in gasoline markets. Prices have been rising and inventories have been dropping on the East Coast, Reuters has reported.
