Moratoriums, and the Limits on Public Land
You'll be able to
- Compare emergency moratoriums under 67-6523 with interim moratoriums under 67-6524
- Lay out a timeline that moves from a pause to permanent code without a gap
- Explain FLPMA coordination and the Granite Rock line between land use planning and environmental regulation
- Describe how state endowment leases and county permits interact, using the Arco example
Writing the code in lessons 2 through 7 takes months. Applications do not wait. A county with no energy standards that receives a 300 MW application next week will review it under whatever its code says today, which is often nothing useful. Idaho lets boards pause. This lesson covers both, then turns to the land where county power is weakest.
Two kinds of moratorium
| Emergency (Idaho Code 67-6523) | Interim (Idaho Code 67-6524) | |
|---|---|---|
| When available | Board finds an "imminent peril to the public health, safety, or welfare" | A plan, plan component or plan amendment is being prepared |
| Finding required | Written statement of reasons | Written finding that an imminent peril to public health, safety or welfare requires the moratorium |
| Procedure | Board may act without a commission recommendation, with whatever abbreviated notice it finds practical | Notice and hearing under 67-6509 (15-day published notice, hearing) |
| Maximum length | 182 days | One calendar year, stated in the ordinance |
| Repeat limits | No consecutive periods; at least one year before the same restrictions return | Must adopt a regular ordinance to continue |
| Best use | An application is imminent and the code has nothing | The county is actively amending its plan's energy policy |
The emergency route is fast but short and cannot be renewed back to back. To keep restrictions past 182 days, the board must adopt an interim or regular ordinance using 67-6509 procedures. The interim route takes a hearing to adopt but buys up to a year, and its legal hook is the plan amendment. That is one more reason to start with the plan.
The same two statutes are what an Idaho county would reach for to pause a data center application. Elsewhere the pause has gone statewide: Maine's Legislature passed LD 307, a moratorium on data centers over 20 MW through November 2027, and Gov. Janet Mills vetoed it on April 24, 2026 over a missing exemption for one local project. The data center planning lesson The Checklist, and the Case For and Against Hosting covers that fight and the federal moratorium bill.
Example: the Owlcreek calendar
Owlcreek's board adopts an emergency moratorium on applications for commercial solar, wind and battery facilities over 50 kW on March 3, with written findings: no standards in the code, a 300 MW application announced, irrigated soils and wells at risk.
- Day 182 falls on September 1 (March 3 plus 182 days).
- Planning commission notice published May 1, at least 15 days before its May 20 hearing on the plan amendment and an interim moratorium.
- Board hearing June 24; interim moratorium adopted, effective to June 23 of the next year.
- Energy chapter and plan amendment adopted the following spring, before the interim moratorium expires.
Bannock County's real path was shorter: a moratorium on October 12, 2023, and a ban adopted in March 2024, roughly five months later.
The findings carry the weight. The Attorney General's takings guidelines, discussed in the appeals and takings lesson, warn that moratoriums need written findings to hold up. Write specific ones: the application or inquiry, the gap in the code, the resources at risk, the timeline to fix it. And keep the pause limited to the uses that need it. A moratorium on all building permits is far easier to attack than one on commercial energy facilities over a stated size.
Federal land: influence, not control
A county cannot zone BLM land. What it gets is written into the Federal Land Policy and Management Act. Under 43 U.S.C. 1712(c)(9), the Secretary must coordinate BLM's land use inventory, planning and management with local governments, stay informed of local plans, give consideration to them, help resolve inconsistencies, let local officials advise on plans and decisions, and keep BLM plans consistent with state and local plans to the maximum extent the Secretary finds consistent with federal law and the act's purposes.
The Supreme Court drew a related line in California Coastal Commission v. Granite Rock Co. (1987). The Court said land use planning "chooses particular uses for the land," while environmental regulation sets limits on damage without dictating uses, and it held that a state's environmental permit requirement on a federal mining claim was not preempted on its face. Applied here: a county cannot tell BLM that a wind farm is a forbidden use of federal land, but county rules that are true environmental or safety standards may sometimes reach a federal project. That line is contested and fact-specific.
Lava Ridge shows both the reach and the limits. BLM approved a scaled-down layout in December 2024, cut from a proposal of up to 400 turbines to roughly 240 (BLM's approval said up to 241; Interior's 2025 cancellation notice says up to 231), with turbines capped at 660 feet. County commissions in the area had passed resolutions opposing it in 2022, before the draft environmental review. Federal approval came anyway. The project was halted on the first day of the new administration in January 2025, and the Interior Department announced it was canceling the approval on August 6, 2025, citing legal deficiencies. The Legislature's HCR 32 later recited its earlier opposition to Lava Ridge. Counties shaped the record and the politics. They did not decide.
The stakes are wider than one project. BLM's Western Solar Plan, reported as finalized in January 2025, added Idaho and four other states and identified more than 31 million acres of public land across 11 western states as available for utility-scale solar applications, according to Western Ag Network's January 2025 report. Whether the current administration keeps, revises or withdraws that plan is worth checking before you cite it.
What a county can do on federal land, then: put clear, mapped energy policy for adjacent and federal areas in its comprehensive plan so BLM has a local plan to be consistent with; request cooperating agency status in environmental reviews; comment on every scoping notice and draft; and regulate the private parcels a federal project needs, such as substations, laydown yards and access roads.
State endowment land: county rules apply
Endowment land is different. The Idaho Constitution, Article IX, Section 8, directs that these lands be managed to "secure the maximum long term financial return" to their beneficiaries. That creates a strong pull toward energy leases. In October 2024, the Land Board voted 3 to 1 to lease 11,160 acres near Arco for wind and solar, a 49-year, six-month lease that staff expected to pay $1.5 million to $2 million a year at full production, roughly $200 to $300 an acre against about 59 cents an acre from grazing.
But Idaho Code 67-6528 says state agencies "shall comply with all plans and ordinances" adopted under LLUPA unless another law provides otherwise. The Arco project went through county review: Bingham County issued a conditional use permit for the wind portion. So a county's energy chapter applies to endowment land within its unincorporated area. Draft with that in mind, and send the Department of Lands notice of every hearing.
Transmission
Idaho Code 67-6508(p) asks counties, after notice from the PUC, to analyze existing and possible routes of high-voltage lines of 115 kV or more on structures 40 feet or taller, including federally designated corridors. Section 67-6528 voids a local action that conflicts with a PUC order directing a utility, where the local government had a chance to be heard by the PUC first. The practical rule: get into the PUC case early when a utility line is proposed, and put corridor preferences (follow existing lines, avoid irrigated ground and towns) in the plan before a route is drawn.
The federal steps, in order. A right-of-way application on BLM land is filed on Standard Form 299 (43 CFR 2804.12). The project has to conform to the approved resource management plan (43 CFR 1610.5-3). NEPA has no acreage trigger: an EIS is required when an action has a "reasonably foreseeable significant effect" (42 U.S.C. 4336); otherwise BLM can use an environmental assessment. The Migratory Bird Treaty Act protects 1,093 species on the 2020 list. Pierson's Imagine a Tarp Over the Desert walks one square mile of structure through these steps.
Common mix-ups
- Claim: A moratorium can last as long as the board needs. What the evidence shows: 182 days for an emergency moratorium, one year for an interim one, and then a regular ordinance or nothing.
- Claim: FLPMA's consistency language gives counties a veto. What the evidence shows: It requires coordination and consistency only to the extent federal law allows. Lava Ridge was approved over local opposition.
- Claim: The Land Board's duty to maximize returns overrides county zoning. What the evidence shows: 67-6528 requires state agencies to follow local ordinances unless another law says otherwise, and the Arco project obtained a county permit.
Reporting angle
- When a moratorium is proposed, request the draft findings and any legal memo the county relies on. Check the dates against the 182-day and one-year limits.
- If a county pauses data center applications, check whether the ordinance exempts any pending project by name or by date. A carve-out for one project is what sank Maine's statewide bill.
- Track BLM right-of-way applications for your county on BLM National NEPA Register (ePlanning), and ask whether the county requested cooperating agency status.
- Watch State Land Board agendas for energy leases and ask the Department of Lands whether it will apply for county permits.
- Ask the PUC whether it has sent the county notice under 67-6508(p) about transmission corridors.
- For any federal project, request the county's written comments and the agency's response to them in the final environmental document.
Research angle
- Moratorium statutes: 67-6523 and 67-6524.
- Federal coordination: 43 U.S.C. 1712; the line between planning and regulation: Granite Rock (1987).
- Lava Ridge: Interior press release, August 6, 2025; also the wind lesson in the renewables course.
- Endowment land: Idaho Constitution Art. IX, Sec. 8 and Land Board agendas on the Department of Lands site.
- Solar on BLM land: BLM Solar Energy Program resources.
- Data center pauses elsewhere: Data Center Knowledge on moratorium proposals (April 14, 2026) and Route Fifty on Maine's LD 307 veto.
Check yourself
1. How long can an emergency moratorium under Idaho Code 67-6523 last?
An emergency ordinance or moratorium may be effective for no longer than 182 days, and the same restrictions cannot be reimposed for consecutive periods; at least one year must pass.
2. What must a board find to adopt an interim moratorium under 67-6524?
67-6524 applies while a plan or amendment is being prepared, requires a written finding of imminent peril for a moratorium, and limits it to one calendar year, adopted with 67-6509 notice and hearing.
3. Under 43 U.S.C. 1712(c)(9), what must BLM do regarding local plans?
FLPMA requires coordination, attention to local plans, help resolving inconsistencies and consistency to the extent federal law and FLPMA's purposes allow. It does not give a county a veto.
4. In California Coastal Commission v. Granite Rock (1987), how did the Supreme Court distinguish land use planning from environmental regulation on federal land?
The Court treated them as distinct and held state environmental regulation was not preempted on its face, while noting the line will not always be bright.
5. Bannock County adopted its moratorium on October 12, 2023, and its ban in March 2024. About how long did the pause last before permanent action?
Mid-October 2023 to March 2024 is roughly five months, well inside the 182-day emergency limit.
6. How did the Arco wind and solar project on state endowment land relate to county zoning?
Reporting on the October 2024 Land Board vote says the county issued a conditional use permit for the wind portion and that work on the solar portion was underway, consistent with 67-6528.
