National Fuel Gas Co. (NFG) subsidiaries have have asked a federal court to review the New York State Department of Environmental Conservation’s (DEC) decision to deny the Northern Access expansion project a water quality certification and other permits. NFG filed a petition for review in the U.S. Court of Appeals for the Second Circuit on Friday. DEC rejected the project’s permits earlier this month, saying construction would negatively impact the environment. The 490,000 Dth/d Northern Access project would expand the Empire and National Fuel systems to move natural gas from wells in northwest Pennsylvania to markets in New York, Canada, the Northeast and the Midwest.
