Updated Study Confirms Ecological Safety of Little Bay Crossing
for Seacoast Reliability Project
Positive results from additional testing to be focus of upcoming technical session
MANCHESTER, N.H. (July 10, 2017) – Eversource has refined the proposed crossing of Little Bay for
the Seacoast Reliability Project to reduce potential environmental impacts. Noteworthy changes in its
updated project application include revised engineering, the inclusion of additional field data, and revised
modeling of the sediment dispersion resulting from the installation of the cable under Little Bay. The
updated results show a significant reduction in the extent of the sediment plume from the cable
“We remain confident that the proposed underwater crossing will be accomplished safely and effectively
without harming the bay and the surrounding environment,” said NH President of Electric Operations Bill
Quinlan. “The revised modeling completed by our environmental consultant for the project confirms and
significantly enhances confidence in our conclusion that there will be minimal adverse environmental
impacts to the bay and the surrounding environment from the cable installation.”
Additional sediment testing was conducted in May in response to reviewer comments that pesticides had
not been included in the original testing. On June 30, Eversource submitted the results of those tests,
which indicate the original conclusions remain valid and there is no evidence of potential contamination
from pesticides or any other pollutant during the cable installation. An additional NH Site Evaluation
Committee technical session on July 11 will provide the opportunity for parties to the permit proceeding
to ask questions regarding the updated sediment and modeling reports.
The Seacoast Reliability Project (SRP) is a new 13 mile transmission line connecting substations in
Madbury and Portsmouth. The SRP is part of the Seacoast Solution, a suite of projects that is needed to
support the reliable delivery of electric power, in order to meet the region’s current demand and to support future economic growth.
Eversource has worked extensively with municipalities, property owners, and environmental groups to
mitigate impacts to sensitive agricultural and historical areas, as well as to ensure the preservation of
Little Bay, and the company remains committed to addressing any additional comments as part of the
state’s rigorous permitting process.
