About 7,700 gallons of fuel spilled from Phillips 66's 238,000 barrels-per-day Bayway refinery in Linden, N.J., after superstorm Sandy pummeled the East Coast a week ago, Reuters reported. 

The Coast Guard made the announcement Monday. The refinery is one of the major gas producers in the region. It was closed ahead of Sandy last week. 

The Coast Guard also said it had recovered 780,000 gallons of an oil-water mixture from Kinder Morgan's Perth Amboy, New Jersey, fuel storage terminal, according to Reuters.
