SWIP-N in Jerome County: A Permit Fight, Step by Step

SWIP-N reaches Midpoint by crossing Jerome County. The federal right-of-way covers the public land. The Idaho PUC certificate covers Idaho Power's share. But where the line crosses private ground zoned for agriculture, Great Basin Transmission needed a county special use permit. In 2025, that permit became the one place where Jerome County residents could put the project in front of officials they elect. What happened is a clean lesson in what a county can and can't do with a line like this.

The account below comes from the Board of County Commissioners' written Memorandum Decision and Order, adopted October 28, 2025, as summarized in Jeff Pierson's reporting files, plus KIVI's coverage of the September hearing. Request the signed decision from the county to read it in full.

The timeline

Date (2025)	Event
June 30	Planning and Zoning Commission approves a special use permit for Great Basin Transmission covering about 23.8 miles of Jerome County, including about 8.05 miles of private land zoned A-1 Agricultural.
July 16	Two residents, Dean Dimond and Julie DeWolfe Arroyo (as the county agenda spells it), file timely appeals to the Board of County Commissioners under the county zoning ordinance and Idaho Code 67-6519.
September 22	At 6 p.m. in the Jack Nelson Room (Room 306) of the courthouse, the board hears the appeal for about two hours and tables it to weigh the evidence, according to KIVI.
October 7	The board resumes at 6 p.m. and votes 2-1 to send the permit back over missing highway district documentation, with Commissioners Ben Crouch and Charles Howell in the majority, KIVI and Heatmap reported. Crouch also asked for an FAA review and an update to a 2010 BLM letter. The county's posted minutes file for that date says no meeting was held.
October 9	The Jerome Highway District sends a written response on the application.
October 28	The board adopts its written decision: most of the approval upheld, a limited remand on one procedural point. It also reviews Great Basin's request to reopen the hearing.
November 24	On remand, Planning and Zoning finds "the original decision is valid and not affected by the Jerome Highway District letter" and votes unanimously to re-approve, adding a condition requiring a road maintenance agreement with the highway district and one requiring highway district permits. Great Basin says the road agreement is already signed.
December 1	A Planning and Zoning special meeting sets the procedure for the written remand decision.

Idaho Power's SWIP-N page lists a Jerome County special use permit among the project's approvals, dated 2025. The remand hearing produced a re-approval on November 24, 2025 (minutes). Idaho Code 67-6521 gives an affected person 28 days after local remedies are exhausted to seek judicial review. No district court petition turned up in news coverage or 2026 county agendas; confirm with the court clerk before calling the permit final.

History explains the "30-year-old permits" phrase in KIVI's headline. The BLM granted Idaho Power the original SWIP right-of-way in November 1994, after a July 1993 final EIS; an appellant cited a 1993 right-of-way. Lesson 5 has the full timeline.

What the appeals argued

One appeal challenged Great Basin's standing to apply, the completeness of the application, hazards to neighboring property, cultural and historic effects, the relevance of claimed statewide power need, the quarter-mile notice radius, and a statement by Great Basin's counsel at the hearing that Idaho Code 31-881 left the commission "no legal choice." The other raised environmental and farm impacts, cultural concerns near the Minidoka National Historic Site, the three-minute limit on public testimony, notice, and whether the line mainly serves out-of-state markets.

At the September hearing, KIVI reported, Rep. David Leavitt testified that SWIP-N and Lava Ridge are "intrinsically connected because there has to be power generated." A Great Basin representative said SWIP is a stand-alone project that does not rely on or trigger new generation in the area. A resident from Eden testified in favor, saying reliable power matters to farms and businesses.

Written testimony came in too. Dan Sakura of Sakura Conservation Strategies, whose father was held at Minidoka as a child and who led the push for the bipartisan legislation that expanded the site, filed a September 15, 2025 letter with the commissioners on the cultural and historic effects. He consults for the Friends of Minidoka; he is not on its board. Heatmap reported the line runs within single-digit miles of the Minidoka National Historic Site. Pierson published it as Jerome County Permit Appeal Testimony. Pierson's SWIP Power Line Zoning Permit Appeal (Sept. 21, 2025) gives the appellants' own summary going into the first hearing: the county didn't follow its own ordinance.

The records request that predicted the remand

Before the board ruled, one appellant asked the planning and zoning office in writing what authority let the county approve applications before outside agencies answered, how long it waited for them, whether the highway district was notified in the Great Basin case, and whether other applications had moved ahead without agency input. The written reply pointed him to Idaho Code and the zoning ordinance in general, quoted fees for paper copies, and called proof of highway district notification "subjective." Pierson published the reply in Is Jerome County Acting in Good Faith?.

Look at the fees, too. The reply quoted $72.75 for the 291-page zoning ordinance at 25 cents a page, plus charges for Idaho Code copies and staff time. Idaho Code 74-102(10)(a) bars charging an Idaho resident for the first 100 pages or the first two hours of labor, so the most that ordinance could cost a resident is 191 pages, or $47.75. A requester who is denied has 180 days to go to district court under 74-115.

Weeks later the board remanded on exactly that point: no written highway district response in the file. A non-answer to a records request is evidence. Keep it, date it and quote it.

What the board decided

• Standing: upheld. Great Basin held recorded perpetual easements and related instruments, which the board found enough to apply.
• Hazards and farm impacts: upheld. The board found no competent evidence from the appellants rebutting the applicant's submittals.
• Cultural and historic resources: upheld, noting that state historic preservation consultation runs through federal permitting and that the commission had conditioned approval on completing it.
• Need and benefit: the zoning ordinance governs land-use compatibility. It does not require proof of statewide energy need or local benefit.
• Notice: the ordinance requires mailed notice within a quarter mile; it does not adopt the BLM's study corridor.
• Idaho Code 31-881: any misstatement by counsel was immaterial, because the commission's decision rested on the zoning ordinance and 67-6519.
• Completeness: appeal granted on this point. The ordinance requires documentation of responses from public agencies, and no written Jerome Highway District response was in the file when the commission approved. The board denied Great Basin's motion to reopen the record and instead sent the case back for a limited hearing on how, if at all, the highway district's October 9 letter changes the approval.

Look at the statute behind the counsel's argument. Idaho Code 31-881 bars local rules that prohibit utility connections, restrict the source of energy service, or require a particular energy type. It says nothing about special use permits for lines. The board didn't rule on what it means; it just said the decision didn't rest on it.

The limits of county power

The board's own decision draws the boundary. A county applies its zoning ordinance to land-use compatibility: hazards, impacts on neighbors, notice, completeness, conditions. It does not decide whether Idaho needs the power. The Idaho PUC answered that question when it granted the certificate on December 12, 2025. It does not control federal land, where the BLM grants rights-of-way. And under Idaho Code 67-6521, an "affected person" with a bona fide property interest can seek review, but the review is of whether the county followed its ordinance and the law.

That is frustrating for residents who object to the project itself. But it also shows where local power is real. Conditions on construction hours, haul roads, weed control, fire plans and reclamation are squarely county business. So is enforcing the ordinance's own procedural requirements, as the remand did.

Lava Ridge in the background

The fight did not start with SWIP-N. BLM approved the Lava Ridge wind project in December 2024, according to Interior, on public land the Legislature's 2025 resolution places in Jerome, Lincoln and Minidoka counties. Jerome County was one of three counties that passed resolutions in 2022 withholding support from it, as the Times-News reported at the time. The Minidoka Pilgrimage Planning Committee told CAISO in September 2024 that seven Idaho counties opposed Lava Ridge and asked CAISO to defer SWIP-N approvals. It also wrote that in 2009 LS Power had sought approval to build SWIP-N through the middle of the Minidoka site. For many residents, the permit hearing was the place to keep fighting a project they saw as one piece of a bigger plan. For Great Basin and Idaho Power, SWIP-N stands on its own. Lesson 5 weighs that evidence.
