Public concern on the record: NE Edge Millstone Nuclear Data Center

Residents raised noise, power-allocation, watercourse, wildlife, health and public-information concerns about the NE Edge Millstone proposal in Waterford's October 2, 2023 meeting record and attached letters. Earlier Siting Council correspondence records a hearing request. The town minutes also record public support. These are historical public concerns, not agency findings of harm or proof of a current project or permit outcome.

Record status: unknown. The later disposition of these historical public concerns, hearing requests and separate boundary procedure is unknown in this bounded review. Acknowledgment, an agenda item or a company update does not establish a granted hearing, current permit, operating impacts or resolution of every concern.
