Oregon has put most new data center construction on hold without passing a law. In a letter dated Friday 9 October, Governor Tina Kotek asked Leah Feldon, director of the state Department of Environmental Quality (DEQ), to use her existing administrative authority to stop work on air and water discharge permit applications for new or expanded data centers until 1 July 2027. Neither the governor's office nor DEQ announced it. The La Grande nonprofit Oregon Rural Action made the letter public on 13 October, and OPB obtained the correspondence from Kotek's office.
Who The Letter Catches
The pause also reaches the cities and counties that run wastewater plants: DEQ is to stop processing their applications to renew or modify discharge permits so that the plants can take data center effluent. OPB's reading is that without air or water permits most large hyperscale facilities cannot be built anywhere in the state, on public or private land. The step widens a pause Kotek placed in September on state-land transactions for data centers, which also runs to July 2027.
How it applies in practice is not settled yet. The letter speaks of new or expanded facilities; DEQ told Data Center Dynamics that it has stopped issuing new or renewed permits and that pending applications are covered, Microgrid Media reports, and the agency is still working out the details. Nobody has said how many applications are waiting. One of them is an air permit for a proposed Amazon hyperscale site in Boardman, where a petition with about 700 signatures asks for an in-person hearing, according to Oregon Rural Action.
Amazon Objects, The Legislature Decides
Amazon has more than a dozen hyperscale data centers in Morrow and Umatilla Counties, OPB writes. Shannon Kellogg, vice president of public policy at Amazon Web Services, said the directive was issued abruptly and without meaningful stakeholder engagement and would halt billions of dollars of planned investment. He named no projects and no figure.
Kotek calls the measure time-limited. It gives her room to review the recommendations of her seven-member Data Center Advisory Committee, whose preliminary report is open for public comment until 24 October, and to bring proposals to the Legislature when it meets in January 2027. She has said she cannot order a statewide moratorium on her own. The city of Hillsboro adopted a 120-day data center moratorium of its own at the end of July.
The Permit That Is Really About The Generators
Outside a site's own power plant, what a data center emits to air comes almost entirely from its standby generators. The air permit is where the number of engines, their test running and their exhaust treatment get fixed, so a project frozen at DEQ is in practice a project whose engines cannot be installed and run. Anyone who ordered generator sets for an Oregon site energizing in 2027 now has equipment that may arrive before the paperwork does, and Georgia has just shown what happens when a power plant goes up ahead of its air permit.
The grid contracts are the other loose end. Microgrid Media points out that under Oregon's POWER Act rules, facilities of 20 MW or more pay for the distribution expansion they trigger and must use at least 90 % of the capacity they contract. Neither the letter nor DEQ says how a paused project's utility contract is treated, or who carries reserved capacity that sits idle until July. For developers of data centers in the state, the January session is where the pause becomes law or ends.
