Update on the Delaware City Refinery

In an updated story from the Middletown Transcript from October 24, Michael Gayda, a spokesman for PBF energy, the company that owns the refinery reports that ‘there is no “high level” risk and that they are working to have the problem fixed by the end of the month.’

What is the definition of “high risk”?

The story also reports that the Delaware City refinery reopened October 7 after being closed for nearly two years. The first report of hydrogen cyanide being released from the facility was received by the National Response Center on October 2, and has been reported every day since then.

Curious how the refinery was permitted to open 5 days after they reported that a boiler on the FCC unit blew a hole in the line causing a release of hydrogen cyanide and that the unit had been shut down for repair?
