The U.S. Maritime Administration (MARAD) and the U.S. Coast Guard (USCG) will have a notice in the Oct. 16 Federal Register about the availability of and public comment opportunities on a Final Environmental Impact Statement on a liquefied natural gas (LNG) import terminal in the waters off of New York.
The FEIS covers the Liberty Natural Gas LLC license application on the Port Ambrose Liquefied Natural Gas Deepwater Port for the importation of natural gas. The Port Ambrose application describes an offshore natural gas deepwater port facility that would be located 16.1 nautical miles southeast of Jones Beach, New York, 24.9 nautical miles east of Long Branch, New Jersey, and 27.1 nautical miles from the entrance to New York Harbor in a water depth of approximately 103 feet.
Publication of this Oct. 16 notice will begin a 45-day comment period. There will be a total of four public hearings held in connection with the application and the FEIS; two public hearings will be held in Long Beach, New York, on Nov. 2 and 3; and two public hearings will be held in Eatontown, New Jersey, on Nov. 4 and 5.
MARAD must issue a Record of Decision (ROD) to approve, approve with conditions, or deny the deepwater port license application, within 90 days following the final license hearing, on or prior to Feb. 3, 2016.
The Port Ambrose facility will be at a different proposed location and include a different design than the previous deepwater port license application submitted by Liberty Natural Gas in 2010. Port Ambrose would consist of two Submerged Turret Loading Buoys (STL Buoys) in federal waters. LNG would be delivered from purpose-built LNG regasification vessels (LNGRVs), vaporized on site and delivered through the STL Buoys, flexible riser/umbilical, subsea manifold and lateral pipelines to a buried 18.8 nautical mile subsea mainline connecting to the existing Transco Lower New York Bay Lateral in New York State waters 2.2 nautical miles southwest of Long Beach, New York, and 13.1 nautical miles east of Sandy Hook, New Jersey. The STL Buoys would be lowered to rest on a landing pad when not in use and would also include a suction anchor mooring array.
The 145,000 cubic meter LNGRVs would have onboard closed-loop vaporization and metering and odorant capability. Each vessel would have three vaporization units capable of maximum send-out of 750 million standard cubic feet per day (MMscfd) (maximum pipeline system flow rate is 660 MMscfd with two buoys) with annual average expected to be 400 MMscfd. The LNGRVs have been designed to use a ballast water cooling system that will entirely re-circulate onboard the vessel during Port operations, eliminating vessel discharges associated with regasification while at the port.
Deliveries through Port Ambrose would be focused during peak demand winter and summer months, and it is anticipated that approximately 45 deliveries will occur each year.
MARAD and USCG are aware that Port Ambrose falls within the proposed area of interest for the Long Island—New York City Offshore Wind Collaborative wind energy project. This project has been acknowledged and considered in the cumulative impacts analysis section of the FEIS based on currently available information.
If approved, the majority of the port and pipeline construction and installation would occur in 2017, with commissioning estimated to be in December 2018.
