The Nuclear Regulatory Commission completed its environmental assessment for Dow and X-energy’s proposed Long Mott Generating Station in Texas and issued a finding of no significant impact, according to company and agency disclosures. The review finished ahead of schedule and keeps the project in the construction permit stage.
The Nuclear Regulatory Commission has completed its environmental assessment for Dow and X-energy’s proposed Long Mott Generating Station in Texas and issued a finding of no significant impact, marking a key regulatory step for the project.
The agency said the review finished ahead of schedule. Dow said the result clears an important hurdle for the advanced nuclear project planned at its Seadrift site, while the NRC’s 2026 news index also lists the release on May 18.
The Long Mott project remains in the construction permit application stage. The environmental assessment does not approve construction on its own, but it is a required part of the federal review process.
The milestone comes about a year after Long Mott Energy, a Dow subsidiary, submitted its construction permit application to the NRC on March 31, 2025.
What comes next
The remaining questions are whether and when the NRC will issue the construction permit, and whether any hearing or adjudicatory issues affect the timeline. For now, the agency’s completed environmental review removes one of the major steps in front of the project.
