Pipeline analysis dramatically underestimates forest impacts, state agencies report

Aug 1, 2017 | Health & Safety, Pipelines

An analysis by Mountain Valley Pipeline of the controversial project’s impacts on intact forests in Virginia underestimated those effects by more than 300 percent, according to an assessment by the Virginia Department of Conservation and Recreation and other state agencies.

In a July 21 filing, the department alerted the Federal Energy Regulatory Commission of “many deficiencies in the MVP approach to evaluate forest fragmentation” that would be caused by the pipeline and the 125-foot wide temporary right-of-way the project would clear of trees and vegetation during construction, as well as the permanently treeless right-of-way of 50 feet in most places.

The agencies said fragmentation of an irreplaceable forest core diminishes its significant, wide-ranging ecological benefits. According to the filing, a “forest core” is an ecological unit that represents an intact block of forest of at least 100 acres.

 In addition, the filing noted that “impacts of forest fragmentation on a diverse suite of forest ecosystem services is not thoroughly acknowledged, analyzed, nor quantified” in the final environmental impact statement for the Mountain Valley Pipeline released by FERC on June 23. And the agencies recommended measures that could help compensate for related damages to intact forests.

On Friday, Diana Christopulos, president of the Roanoke Appalachian Trail Club, alerted FERC that the club is “very disappointed in the FEIS treatment of forest fragmentation,” which is defined as the breaking of large, contiguous forested areas into smaller, disconnected pieces.

As an interstate pipeline, the 303-mile Mountain Valley project needs FERC’s approval before construction can begin.
