This is a reopening of the public comment period for DOE's Notice of Early Public and Governmental Engagement on the potential designation of three National Interest Electric Transmission Corridors (NIETCs): the Tribal Energy Access, Southwestern Grid Connector, and Lake Erie-Canada corridors. The original notice, published December 14, 2024 (89 FR 101597), solicited input on the possible scope of analysis including environmental, cultural, and socioeconomic effects of potential NIETC designations. DOE received requests for more time and has extended the comment deadline from February 14, 2025 to April 15, 2025. Substantive analysis of impacts and alternatives is in the underlying notice, not this procedural extension.12
