On February 20, 2026, the U.S. Forest Service (USFS) published a proposed rule that would overhaul how locatable mineral exploration and mining are reviewed on National Forest System lands for the first time since 1974. Proposed Rule, Locatable Minerals, 91 Fed. Reg. 8316 (Feb. 20, 2026). The proposal—issued at 91 Fed. Reg. 8316—shifts from a subjective trigger (“likely to cause a significant disturbance”) to objective thresholds, creates a new Operating Notice review track for lower‑impact exploration work, updates operating standards and enforcement, and expressly aims to support reliable supplies of strategic and critical minerals. Public comments are due April 21, 2026.
USFS frames the update as both a modernization and an efficiency measure: the agency seeks to “improve the efficiency and transparency” of its regulation of locatable mineral operations on National Forest System lands while “minimiz[ing], to the fullest extent practicable, adverse impacts on surface resources,” and to do so in closer alignment with the Bureau of Land Management (BLM). USFS also links the proposal to executive‑branch priorities to streamline permitting and bolster domestic mineral supply chains. USDA Forest Service News Release, U.S. Forest Service seeks public comment on proposed mineral operations rule revisions, https://www.fs.usda.gov/about-agency/newsroom/releases/us-forest-service-seeks-public-comment-proposed-mineral-operations (Feb. 19, 2026).
Background—How the Current Rule Works
Since 1974, the Forest Service’s locatable minerals program has regulated surface use and occupancy for mining on National Forest System lands under 36 C.F.R. part 228, subpart A. Under that framework, an operator could submit a Notice of Intent for activity that might cause disturbance; if the District Ranger determined an operation was “likely to cause a significant disturbance of surface resources,” the operator had to submit a Plan of Operations (PoO) for approval before proceeding. That significant‑disturbance test—adopted in a different era—has been criticized as subjective, slowing reviews and producing inconsistent outcomes across forests. USFS reports that from 2004–2019 it processed 3,171 PoOs, most disturbing less than five acres, often for short‑term exploration; GAO has also highlighted backlogs and delays from incomplete filings. The 2026 proposal targets those issues by replacing the subjective trigger with objective criteria (including a >5‑acre threshold) and by requiring pre‑submittal meetings and completeness checks before NEPA begins.
What’s New in the Proposed Rule
The centerpiece of the proposed rule is a tiered review framework that replaces the 1970s standard with specific, activity‑based thresholds: “The Forest Service proposes to replace the existing subjective threshold of ‘likely to cause a significant disturbance of surface resources’ with a threshold comprising specific requirements.” Under the new criteria, “operations resulting in surface disturbance greater than 5 acres,” “operations other than exploratory or investigative operations,” and certain resource‑protection circumstances would require a PoO. 91 Fed. Reg. at 8317.
For activities below those thresholds, USFS proposes a new Operating Notice: operations that do not meet PoO criteria—but are more than “no‑notice”—would file an Operating Notice “which can be prepared by operators and reviewed by the Agency much more quickly and efficiently.” USFS estimates an “annual average of 62 operations that currently require a plan of operations would be conducted under an operating notice” if the proposed rule is adopted. 91 Fed. Reg. at 8317.
To reduce delays caused by incomplete submissions, USFS would strengthen the front end of its review process. The rule would require a pre‑submittal meeting for Operating Notices and PoOs, adopt a detailed information list, and require the agency to confirm completeness before initiating any required NEPA analysis—measures intended to improve plan quality and shorten review times. 91 Fed. Reg. at 8317-8318.
The proposal also modernizes terminology (adding twelve definitions, including “exploration,” “geotechnical and water resource investigations,” “financial assurance,” “reasonably incident uses,” and “reclamation”) and seeks closer alignment with BLM’s surface‑management framework to minimize confusion for operators whose projects span multiple federal authorities—such as claims or drill pads on National Forest System lands with access roads, power lines, or staging areas crossing onto BLM‑managed lands (or vice versa). 91 Fed. Reg. at 8319–8321.
Finally, USFS proposes enhanced operating standards, clearer modification procedures, stronger enforcement, and updated financial assurance rules—including how bonds are established, maintained, and released.
Why It Matters in Idaho and the West
For exploration teams planning short‑season programs across Idaho’s Boise, Payette, Salmon–Challis, Idaho Panhandle, or other National Forests—and for projects that touch the Humboldt–Toiyabe in Nevada—the proposed Operating Notice track may make the difference between mobilizing on time and missing the season. Short of the five‑acre disturbance threshold, a well‑documented notice and a productive pre‑submittal meeting may advance a drill campaign by weeks, especially when weather windows are tight. USFS estimates that approximately 62 plans per year would shift from PoO to Operating Notice, which signals a meaningful change in administrative throughput for lower‑impact exploration work.
USFS also aims to harmonize its surface‑management approach with BLM, reducing cross-agency inconsistencies for operators whose footprints straddle federal jurisdictions—common in Idaho/Nevada corridors where access roads, staging areas, or power lines cross national forest boundaries.
Environmental Performance: Water, Monitoring, Reclamation, and Bonding
The proposed rule pairs streamlining with specific operational upgrades: it would codify surface‑resource protection and operating standards (including how to modify approvals), elevate water protection by calling for geotechnical and water‑resource investigations and for monitoring plans to be addressed in submissions where applicable, enhance enforcement procedures, and modernize financial assurance—setting clearer rules for establishing, maintaining, and releasing bonds so reclamation and long‑term obligations are funded. It also installs front‑end quality controls—a pre‑submittal meeting, a detailed information list, and a completeness determination before NEPA—to reduce delays from incomplete submissions.
Practically, exploration companies should budget and schedule for baseline hydro‑geotechnical work (e.g., desktop hydrogeology, spring/stream reconnaissance, and monitoring approaches appropriate to the site) and build a documented water‑monitoring plan into their Operating Notice/PoO packages—steps that were often handled informally or later in the process under the 1974 framework. Companies should expect to integrate field‑season water sampling and reporting milestones alongside drill mobilization so that monitoring and reclamation commitments are traceable from day one.
NEPA and ESA Under the Proposed Rule
A PoO approval remains a federal authorization, ordinarily a “major Federal action” that triggers NEPA review and—in cases where the project may affect a listed species or designated critical habitat—Endangered Species Act (ESA) Section 7 consultation with U.S. Fish and Wildlife Service (USFWS) or National Marine Fisheries Service. In contrast, a properly scoped Operating Notice that does not require a formal federal authorization may, in some cases, not require NEPA review under CEQ’s “substantial Federal control and responsibility” standard; still, USFS retains discretion to elevate to a PoO when resource‑protection criteria are implicated.
“No‑notice” activity is not “no‑risk.” Operators always remain subject to ESA Section 9’s prohibition on unauthorized “take.” Where incidental take cannot be avoided and there is no federal action to support Section 7 consultation, the non‑federal pathway is an ESA Section 10 incidental take permit supported by a habitat conservation plan.
Early utilization of the USFWS’ Information for Planning and Consultation (IPaC) tool and other desktop environmental screens will benefit operators, who can use the results to refine pad locations, access routes, and timing to avoid or minimize “may affect” scenarios. Operators can then bring that analysis—maps, species lists, avoidance measures, and design alternatives—to the pre‑submittal meeting so ESA/NEPA issues are surfaced early enough to keep the project on schedule.
Policy Backdrop: Streamlining and Critical Minerals
USFS’s February 19, 2026 news release emphasizes that the proposed rule is “designed to streamline review procedures and improve customer service” while supporting executive orders on “Unleashing American Energy,” a “National Energy Emergency,” and “Immediate Measures to Increase American Mineral Production.” At the same time, the agency stresses, “This isn’t about relaxing the rules,” but about clarity, efficiency, and alignment with BLM. The proposed rule’s preamble likewise underscores the dual goals: efficiency/transparency and minimizing adverse surface impacts, together with supporting strategic and critical minerals policy. USDA Forest Service News Release, Feb. 19, 2026; 91 Fed. Reg. 8316.
Early coverage reported mixed reactions—some highlighting improved oversight and GAO‑responsive process fixes, others concerned about reduced public participation in the lighter review tracks—underscoring that how forests exercise elevation discretion will draw scrutiny.

How Idaho‑ and Nevada‑Focused Explorers Can Prepare Now
For exploration companies planning 2026 and 2027 field programs, several practical steps follow directly from the proposed rule’s structure. First, map each project to the appropriate review track and build a contemporaneous record supporting that placement—documenting why an activity qualifies for an Operating Notice (e.g., less than five acres of disturbance, exploratory scope, and initial resource screens)—and bring that analysis to the pre‑submittal meeting (disturbance tables, IPaC results, cultural checks, and a reclamation approach keyed to the proposal’s definitions). This supports use of the lighter track and expedites NEPA if elevation to a PoO is later required.
Second, treat bonding and water protection as front‑end design variables: anticipate more explicit monitoring commitments and reclamation detail at the outset, and be prepared to discuss financial assurance—including, where appropriate, trust‑style mechanisms—before fieldwork begins.
Third, where footprints span both BLM and USFS, use the alignment objective to standardize disturbance accounting, BMPs, and reclamation specifications across agencies (translated into each agency’s forms) to reduce iterative requests and keep short western field seasons on track.
Bottom Line
If adopted substantially as proposed, USFS’s rule will give exploration teams in Idaho and the broader West clear thresholds, a workable Operating Notice review track, modernized standards and enforcement, and closer BLM alignment—all of which should reduce uncertainty and help time‑sensitive programs mobilize on schedule. In exchange, USFS is asking for front‑loaded diligence and predictable environmental performance, especially around water and bonding. For companies already operating to contemporary best practices, that is a practical trade that supports both project delivery and resource protection on National Forest System lands.
