What changed
FERC's Office of Energy Projects released an Environmental Assessment for Great Lakes Gas Transmission Limited Partnership's proposed Maximum Allowable Operating Pressure modification under their Section 157.208 blanket certificate. The EA assesses potential environmental impacts of the operating pressure change and was prepared in accordance with the National Environmental Policy Act review requirements.
