Climate & Infrastructure

A new report from the Union of Concerned Scientists says hundreds of coastal Superfund sites – including several in New Hampshire – face new risks of flooding due to climate change.

The analysis looked at federal toxic waste sites within 25 miles of the East and Gulf Coasts, and found that New Jersey, Florida and New York have the most sites at risk of extreme flooding. Many are concentrated along the I-95 corridor. 

Liberty Utilities says it will not build the proposed Granite Bridge natural gas pipeline in Southern New Hampshire, after finding a cheaper way to serve new customers by using existing infrastructure.

The company told the state of the change in plans in a Public Utilities Commission filing Friday afternoon. 

The $340-million pipeline plan dated to late 2017 and drew fierce opposition from climate change activists, who oppose any expansion of fossil fuel infrastructure in the region.

The state is launching a broad new effort to find ways to reduce the air emissions that drive respiratory disease and climate change in New Hampshire.

The non-partisan Emissions Commission meets for the first time next week and will include members of state agencies, utilities and the legislature, along with health, business and environmental advocates.

Environmental groups want federal regulators to reconsider a new water discharge permit for New England’s largest coal-fired power plant – Merrimack Station in Bow.

The Environmental Protection Agency permit was issued in May after many years of delay.

It dictates how the power plant uses water from the Merrimack River – burning coal to heat the water into steam that generates electricity, before putting that hot water back into the river.

A major new study says federal flood maps have far underestimated how many properties in New Hampshire and nationwide are at risk from substantial flooding, now and in the coming decades.

The report, out Monday, comes from a range of academic institutions and the nonprofit First Street Foundation.

State officials say too much salt is being applied to New Hampshire roads this winter, and they worry that warmer, wetter winters could make the problem worse in future.

State officials are using federal money to look at how rising seas will threaten major highways and connecting routes on the Seacoast.

The project, funded by the National Oceanic and Atmospheric Administration, will build a "vulnerability assessment" for the I-95, Route 1 and Route 1A corridors, and local connector roads, including Routes 101 and 286.
