Mongaup River Relicensing Information


The Mongaup River hydroelectric facilities operate under three licenses issued by the Federal Energy Regulatory Commission (FERC): Swinging Bridge is Project No. 10482; Mongaup Falls is Project No. 10481; and Rio is Project No. 9690. Eagle Creek Hydro Power, LLC, Eagle Creek Land Resources, LLC, and Eagle Creek Water Resources, LLC (all subsidiaries of Eagle Creek Renewable Energy, and jointly referred to as the "licensee") are the joint holders of all three licenses. The facilities' current licenses were issued in 1992 and expire in 2022. The licensee is seeking to relicense all three projects concurrently using the Integrated Licensing Process.

The Licensee will conduct studies during the remainder of 2018 and file an Initial Study Report with the FERC by February 9, 2019.
