Federal regulators will give Seacoast residents more time to weigh in on construction permits for a new transmission line.
But they still need permits from the U.S. Army Corps of Engineers to build in sensitive wetlands and tidal areas.
The Army Corps is now taking public comment through May 23 on the terms of those permits.
Environmental advocates have called on the agency to hold a public hearing as part of that process.
Meanwhile, Eversource is conducting survey work, tree trimming and other initial construction of the project.
The transmission line will span about 13 miles between Madbury and Portsmouth, with a mile buried beneath Little Bay.
Construction is planned to wrap up early next year.
Eversource will also hold an open house in the town of Durham Wednesday night at Oyster River High School from 6 to 8 p.m. where residents can ask questions about the project.
