Process Description
NSPW filed a Notice of Intent (NOI) to file an application with FERC to obtain a subsequent license for the Project. The NOI was accompanied by a Pre-Application Document (PAD). Pursuant to 18 CFR, Section 5.5, the filing of the NOI marks the beginning of the licensing process and sets the schedule for further licensing activities. In addition to filing the PAD and NOI, a request was filed asking FERC to allow NSPW to utilize the Traditional Licensing Process (TLP). The request to use the TLP was filed as a related submittal under 18 CFR, Section 5.3. NSPW’s rationale and justification for utilizing the TLP was included in the submittal.

The initial activities on the TLP plan and schedule included filing the PAD and NOI, as well as the request to use the TLP. FERC approved utilizing the TLP on January 21, 2021, beginning stage one of the formal three-stage consultation process. In accordance with this schedule, NSPW held a virtual Joint Agency Meeting on March 11, 2021. Comments on the PAD and study requests were submitted by the National Park Service, Trego Lake District, and Wisconsin Department of Natural Resources.

Stage two consultation began after written comments were received on the PAD. This consultation included studies that were needed to identify potential resource impacts. The final study summary including the final study plans addressing stakeholder comments was submitted to FERC on April 21, 2022. Studies were conducted in 2022. Final study results were included in the Draft License Application (DLA) which was filed on June 29, 2023. Stakeholder review of the DLA is expected to occur between June 29, 2023 and August 28, 2023 (90 days).

Stakeholder review of the DLA occurs within 90 days of filing. The Final License Application (FLA) will be filed with FERC by November 30, 2023. Once the FLA is filed, stage three consultation would begin.

It is anticipated the following will occur between November 23, 2023 and November 30, 2025:

    • FERC review of the FLA
    • Issuance of FERC acceptance letter
    • Submittal of stakeholder comments, terms, and conditions
    • Scoping under the National Environmental Policy Act (NEPA)
    • Preparation of Draft Environmental Assessment (EA) or Environmental Impact Statement (EIS)
    • Resolution of issues, if any, under Federal Power Act Section 10(j)
    • Preparation of final EA or EIS

Based on this anticipated schedule, FERC would issue a License Order by November 30, 2025.
