Viewshed and noise – The Downeast LNG pier will be aligned perpendicular to the coast, limiting the visual impact along the coast. There will be minimal lighting, which will face inward to the coast. The storage tank will rest below the horizon of Robbinston Ridge, with tree cover in front. And while there will be limited noise during the docking of a ship, there will be no offsite impacts due to noise from the regular operations of the terminal and regasification facility.
Rights of access to waterway – There will be no restricted access for any vessel when a LNG ship is docked at the Downeast LNG terminal beyond the standard exclusion zone. All LNG ships have a moving exclusion zone during transit.
Safety – The entire project will be built to the highest safety standards, including a full containment tank. There will be no safety issues for any communities in the US or Canada.
Ferries and whale watching vessels – All ferries and whale watching boats will be given advanced notice of ship arrivals for their scheduling purposes. LNG ships will transit quickly through local waters and ships will arrive approximately only once every 12 days.
Right Whales – There is no right whale activity along the routes in Passamaquoddy Bay or Head Harbour Passage that LNG ships will transit. While the major concern for the whale population is fishing gear entanglement, mammal watchers will be posted on vessels transiting these waters as an extra precaution.
Ship Navigation – Ease of navigation is a major attribute of the project. Ships will be subject to a current of less than 1.4 knots at berth, with average winds of less than 25. The site has a favorable wave regime and minimal swells and a draft of 50 feet at mean lower low water (MLLW).
During transit there is an under keel clearance of transit mostly +80 ft at low tide, with tides of 19 feet. The narrowest passage in the shipping channel is about 2,500 feet, providing a sufficient turning radius and not impeding any existing ship traffic.
The total transit time from the pilot station to berth is estimated at 3 hours, covering a distance of about 13 nautical miles.
