Mack PointYes· Approx. 65 acres available (according to Sprague) and 35 acres infill required; 100 acres total

· Contiguous with no narrow areas and on the waterfront		Meets minimum 1,500 feet · Approx. 2,000 feet from federal channel; dredge required for berth pocket for channel access to the full length of wharf

· FEMA flood elevation of +15 feet NAVD88

· Deck elevation would be set at +15 feet; the site would slope up at 1% 		· Introduction of new vessels would affect existing vessel traffic

· Pilots noted winds across the beam (widest part of the ship) would make maneuverability at berth (oriented east-west, perpendicular to prevailing winds) difficult 		· 500,000 cubic yards

· Maintenance dredging to federal channel to occur

· CAD cell required		Approx. 350,000 cubic yards net import · Yes. 65 acres identified by Sprague is available, but subject to change

· Sprague Operating Resources, LLC operates Mack Point and owns the liquid bulk pier; Maine Port Authority owns the dry bulk pier, which Sprague operates

· Sprague Energy and Canadian Pacific Rail own land in this area; Irving leases land in this area.		· Construction cost: $400M- $500M

· Prelim. lease est.: $290M-$490M over 50-yr design life

Hybrid (Mack Point + Sears Island)Yes· Mack Point includes approx. 65 acres available and 14 acres infill required (79 acres total) and Sears Island includes approx. 35 acres available and 25 acres infill required (60 acres total)

· Combined total area exceeds minimum 100 acres because of separated operations

· At each location the site is contiguous with no narrow areas.

· Both sites are on the waterfront for marshalling/integration facility on Sears Island and foundation assembly/ fabrication/ manufacturing on Mack Point 		· Meets minimum 1,500 feet

· Mack Point has independent 1,100 feet and Sears Island has independent 1,100 feet. The total length is greater than minimum 1,500 feet because both sites require enough frontage to accommodate a delivery vessel and an offshore wind foundation.		· Marshalling would occur from Sears Island adjacent to federal channel; dredge not required for berth pocket

· Maintenance dredging to occur to restore consistent channel depth of -35 ft MLLW		No vertical or horizontal navigational restrictions· Tidal range of approx. 10 feet

· FEMA flood elevation of +15 feet NAVD88

· Deck elevation would be set at +15 feet; the site would slope up at 1% 		· Introduction of new vessels would affect existing vessel traffic

· No new berths proposed at Mack Point. Vessels accessing Mack Point would share use of the existing bulk pier with existing users

· Pilots noted the north-south wharf configuration, parallel to prevailing winds, is favorable for berthing 		· 320,000 cubic yards at Mack Point

· Maintenance dredging to federal channel to occur

· CAD cell required		Approx. 100,000 cubic yards net import, if sites are constructed simultaneously· Yes. 65 acres identified by Sprague is available, but subject to change

· Sprague Operating Resources, LLC operates Mack Point and owns the liquid bulk pier; Maine Port Authority owns the dry bulk pier, which Sprague operates

· Sprague Energy and Canadian Pacific Rail own land in this area; Irving leases land in this area.
