Notice of Scoping for Connecticut Army National Guard Aircraft Hangar Alteration/Addition

Project Title: Proposed Aircraft Hangar Addition/Alteration

Address of possible location: 139 Tower Avenue

Municipality where proposed action might be located: Groton

Project Description:

The Groton-based unit is one of only four units in the U.S. Army’s footprint designated for large-scale rotary-wing maintenance and covers a geographical region spanning fourteen states. The unit’s state-of-the-art maintenance facility allows it the capability to repair and test nearly every component in the UH-60 Blackhawk and CH-47 Chinook helicopters. The daily work being performed by the TASMG, including soldiers, technicians, and contractors, is focused on keeping the military’s current operational fleet in the air.

The modernization of this facility is required for the national mission of theater aviation sustainment maintenance. This facility continues to expand in mission requirements, required quantity of space, and personnel assigned. This project is to construct an addition/alteration for TASMG personnel of permanent type construction to serve the missions of the assigned units.  The space will permit all personnel to perform the necessary tasks that will improve the unit's readiness posture.

Known as the “Proposed Aircraft Hangar Addition/Alteration”, the Proposed Action to be assessed under the Connecticut Environmental Policy Act (CEPA) process consists of the following elements:

  • Renovation of 33,127 square feet (SF)

  • Addition of 56,579 SF

The Connecticut Army National Guard will incorporate comments from the public and evaluate the Proposed Action. Direct, indirect, and cumulative impacts associated with the Proposed Action will be assessed.
