LNG Terminals

One of the new liquefied natural gas (LNG) terminals is east and slightly south of Nahant; the other is east and slightly north. Both LNG terminals are in a small triangle of ocean surrounded by Stellwagen Bank National Marine Sanctuary (NMS), two state ocean sanctuaries, the Boston Harbor shipping lanes and the precautionary area. An extraordinary 79 out of the 350 endangered North Atlantic right whales still left alive were detected in April, 2008 in Cape Cod Bay and the area covered by this map.

No Discharge Area

An announcement by the Environmental Protection Agency (EPA) accepting the Lower North Shore No Discharge Area (NDA) was made on March 18, 2009. This NDA designation bans discharge of wastewater from boats and ships into the coastal waters of Nahant, Lynn, Swampscott, Saugus, and Revere.

This is particularly important for Nahant, because not only local boats, but also boats and ships headed to and from Boston Harbor will be prevented from discharging into local waters.

Nahant Important Bird Area

Birds constitute the most significant wildlife of Nahant. The beaches and mudflats are a critical habitat for thousands of gulls and other shorebirds.

In winter, the waters surrounding Nahant support most of the species common to New England waters including gulls, loons, grebes, cormorants, geese, and large flocks of ducks. Migratory birds feed and rest here on their long spring and fall journeys.

Eelgrass

Eelgrass beds are the wetlands of the shallow coastal ecosystems. They are critical because they supply food and camouflage for a wide number of commercially and recreationally significant animals and their prey.

In addition their naturally occurring leaf canopy soothes the water and acts as a filter for latent matter.
