The Federal Energy Regulatory Commission (FERC) published a Notice of Scoping Period Requesting Comments on Environmental Issues in the Federal Register on October 8, 2026 (FR Doc. 2026-20656, 91 FR 64372) for relicensing the Ogdensburg Hydroelectric Project (Project No. 9821-109) on the Oswegatchie River in the city of Ogdensburg, St. Lawrence County, New York.
The applicant, Ampersand Ogdensburg Hydro, LLC of Boston, filed for a new license on May 30, 2025. FERC staff will prepare a National Environmental Policy Act document on the effects of relicensing and say they do not plan to issue a separate scoping document.
