Officials managing decades of nuclear legacy waste at Idaho National Laboratory are mobilizing support across East Idaho counties to oppose potential changes that could dramatically reduce the pace of contaminated material shipments leaving the state.
Dana Kirkham, Vice President of Regulation with Idaho Environmental Coalition, presented the case to Jefferson County Board of Commissioners on June 22, warning that proposed alterations to a 1995 Idaho Settlement Agreement could throttle current operations to a fraction of their present capacity.
Current Operations and Stakes
The Idaho Cleanup Project, managed by Idaho Environmental Coalition, bears responsibility for exhuming waste and contaminated soil buried in the Idaho Desert during the 1950s—a legacy of early atomic development now threatening the Snake River Plain Aquifer. The project currently moves 7 to 12 loads of waste per week out of state, a pace that depends on maintaining the existing settlement framework with New Mexico, which receives the material at a designated disposal facility.
The cleanup operation anchors regional employment, with approximately 2,000 workers on site. Kirkham emphasized the local roots of the workforce, noting that “Ninety-five percent of our employees are homegrown Idahoans.” Jefferson County alone faces potential economic disruption affecting 189 families directly tied to the project.
Idaho National Laboratory itself operates under management by Battelle Energy Alliance, while the Naval Reactors facility falls under Fluor Marine Propulsion. Together, these entities manage some of the nation’s most complex nuclear infrastructure and environmental remediation challenges.
Proposed Changes and Their Impact
New Mexico has requested permission to amend the settlement agreement, seeking changes that would significantly alter waste disposal arrangements. The current agreement mandates that 55 percent of waste arriving at the New Mexico facility must originate from Idaho. Under the proposed modifications, Idaho shipments could drop from the current 7 to 12 per week to merely 7 to 12 per year—a reduction of more than 99 percent in some scenarios.
Kirkham underscored the interconnected nature of the three managing entities, explaining that “If we’re not doing our job, the other two can’t do their job.” The cleanup project forms the foundation of a coordinated system; disruption at one point cascades across the entire operation.
Regional Coalition Building
The effort to preserve current shipment rates extends beyond Jefferson County. Idaho Falls, Ammon, Bonneville County, and Butte County have already submitted formal statements during the public comment period, which concluded in late June. Officials indicated that additional opportunities for public comment would open soon, signaling an extended engagement process.
The push to secure county-level support reflects broader concerns about the long-term viability of cleanup operations. Slowing waste removal jeopardizes not only jobs but also the timeline for reducing contamination risk to Idaho’s critical groundwater resources. The Snake River Plain Aquifer supplies drinking water and irrigation to hundreds of thousands of residents and acres of farmland across southeast Idaho.
What Comes Next
The settlement agreement modification process remains in motion, with federal and state officials weighing the implications. Additional public comment periods are expected to provide counties and communities further opportunity to voice concerns. Meanwhile, the cleanup project continues operating under current parameters, with officials pressing for preservation of existing shipment schedules and operational frameworks that have sustained both remediation progress and regional economic stability.
