UNITED STATES OF AMERICA FEDERAL ENERGY REGULATORY COMMISSION Black River Limited Partnership Project No. 11730-029 NOTICE OF AVAILABILITY OF ENVIRONMENTAL ASSESSMENT (January 27, 2026) In accordance with the National Environmental Policy Act of 1969 and the Federal Energy Regulatory Commission's (Commission or FERC) regulations, 18 C.F.R. Part 380, Commission staff reviewed Black River Limited Partnership's application for non-capacity amendment of license of the Alverno Hydroelectric Project No. 11730 and have prepared an Environmental Assessment (EA) for the project. [1] The licensee proposes to amend the operating requirements of the project pursuant to Article 404 of the license to be consistent with an amended water quality certification issued by the Michigan Department of Environment, Great Lakes, and Energy on January 4, 2023, and to address an ongoing compliance proceeding at the project. The Alverno project is located on the Black River in Cheboygan County, Michigan, and does not occupy federal lands. The EA contains Commission staff's analysis of the potential environmental effects of the proposed amendment, alternatives to the proposed action, and concludes that the proposed amendment, would not constitute a major federal action that would significantly affect the quality of the human environment. The EA may be viewed on the Commission's website at http://www.ferc.gov using the "eLibrary" link. Enter the docket number (P-11730) in the docket number field to access the document.
