The Federal Energy Regulatory Commission has accepted PacifiCorp's application for an exemption from licensing covering the Ashton Hydroelectric Project, a 6.7-megawatt run-of-river facility on the Henry's Fork of the Snake River in Fremont County, Idaho. The notice, published in the Federal Register on June 18, 2026 under Project No. 2381-071, states that the application has been accepted for filing and is now ready for environmental analysis. PacifiCorp filed the application on December 16, 2025, and FERC has set a 5:00 p.m. Eastern Time deadline of August 14, 2026 for motions to intervene, protests, comments, recommendations, and terms and conditions. Reply comments are due September 28, 2026.

For a project-tracking reader, the procedural posture matters as much as the megawatts. "Ready for environmental analysis" is the milestone at which FERC's staff begins assembling the record it will use to decide whether to issue the exemption, and "intent to waive scoping" signals that the Commission does not plan to hold separate scoping meetings before that analysis proceeds. The filing was submitted under 18 CFR 16.22 and the Public Utility Regulatory Policies Act of 1978, as amended by the Hydropower Regulatory Efficiency Act of 2013 — the statutory framework that governs small hydropower exemptions and was written to shorten the path for projects of this size.

What the project description specifies

The notice lays out the physical project in unusual detail for a docket entry. The Ashton Hydroelectric Project consists of a 56-foot-high, 222-foot-long earth and rock-filled dam covered with roller-compacted concrete on the downstream slope, with a crest elevation of 5,156.6 feet; an 82-foot-long reinforced concrete spillway with six 10-foot-high by 12-foot-wide radial gates; a 280-foot-long, 15-foot-high diversion tunnel through the right abutment; and an intake built around a reinforced concrete control structure with two stainless steel slide gates. The impoundment is a 392.9-acre reservoir holding 6,119 acre-feet of gross storage at a normal maximum water-surface elevation of 5,155.9 feet.

Generation comes from a reinforced concrete powerhouse containing three turbine-generator units: two rated at 2.0 megawatts each and one rated at 2.7 megawatts, for a total installed capacity of 6.7 megawatts. The notice also describes an 80-foot-wide tailrace and a 46/2.3-kilovolt step-up transformer that ties the powerhouse to the grid. The project occupies 15.6 acres of federal land managed by the U.S. Bureau of Land Management, a detail that brings federal land-management coordination into the environmental review alongside FERC's own analysis.

Why the docket is worth watching now

Small hydropower is the part of the FERC docket where the relicensing and exemption pipeline is most active, and the Ashton filing is a clean example of how a facility moves through it. The exemption-from-licensing route is reserved for qualifying small projects and is designed to be lighter-weight than a full license proceeding, but it still runs through the same environmental-analysis machinery and the same public-comment and intervention process. The August 14 deadline is the operative date for any resource agency, tribe, conservation group, or other party that wants standing in the proceeding; under FERC's Rules of Practice and Procedure, intervenors must serve their filings on every person on the official service list, and any comments touching a particular resource agency's responsibilities must be served on that agency as well.

The applicant contacts named in the notice are William Shallenberger, Vice President of PacifiCorp's Renewable Resources group in Portland, Oregon, and Jaime Campbell-Lavallee, a senior environmental analyst based at the Grace Power Plant in Grace, Idaho. FERC's project coordinator for the docket is Amy Chang in the Northwest Branch of the Division of Hydropower Licensing. The Commission is encouraging electronic filing through its eFiling system, with a parallel eComment channel for brief comments up to 10,000 characters that does not require prior registration. All filings, FERC notes, must identify the project by name and docket number on the first page: Ashton Hydroelectric Project (P-2381-071).

The procedural sequence built into this single notice is itself worth reading closely, because FERC has bundled several steps that often arrive separately. The notice simultaneously accepts the application for filing, states the Commission's intent to waive scoping, declares the docket ready for environmental analysis, and solicits motions to intervene, protests, comments, recommendations, and terms and conditions. Compressing those steps signals that the Commission considers the application record complete enough to move directly into environmental review without a separate scoping phase — a posture consistent with the streamlined intent of the exemption route, but one that also shortens the runway for parties who want to shape the issues the analysis will examine. The two-stage comment structure, with initial filings due August 14 and reply comments due September 28, gives the applicant and intervenors a defined window to respond to one another's submissions before staff finalizes its analysis.

The terms-and-conditions language in the notice is the part resource agencies tend to watch most. Under the statutory framework FERC cites, federal and state resource agencies can submit mandatory or recommended conditions — covering matters such as fish passage, minimum flows, and protection of the federal land the project occupies — that the Commission must consider as it crafts any exemption it grants. Because the Ashton project sits on 15.6 acres of BLM-managed land and impounds a 392.9-acre reservoir on the Henry's Fork, the conditions other agencies attach during this window can materially shape how the facility is ultimately operated. That is why the August 14 deadline functions as more than a formality: it is the point at which the operating constraints on the project, if it advances, begin to take written form.

What the record establishes at this stage is narrow but concrete. FERC has not granted the exemption; it has accepted the application, declared the docket ready for environmental analysis, and opened the window in which the public record will be built. The numbers in the project description — 6.7 megawatts of installed capacity across three units, a 392.9-acre reservoir, 6,119 acre-feet of storage, and 15.6 acres of BLM land — are the figures the environmental analysis will be measured against, and they are the figures any intervenor will be working from when the August deadline arrives. For readers who track which gigawatts on paper actually advance toward construction, the Ashton docket now has a calendar attached to it.
