What did the governor’s letter ask DEQ to do?
On October 9, 2026, Oregon’s governor wrote to the director of the Department of Environmental Quality, the state agency that issues pollution permits. The letter asks the director to use her existing authority and discretion to stop processing and issuing air and water discharge permit applications for new or expanded data center facilities until July 1, 2027. Governor’s letter The governor wrote that the pause gives her time to review her Data Center Advisory Committee’s recommendations and leaves room for reforms in the 2027 legislative session. Neither her office nor the agency announced the letter, and it became public on October 13. OregonLive
The letter is a request to an agency head. It is not a new statute or a new rule. The governor has said before that she lacks the power to order a statewide moratorium without the Legislature. Capital Chronicle So the pause rests on how the agency chooses to handle its own permit work.
Which permits and applications the pause reaches
The letter names four permits, two for air and two for water. An air contaminant discharge permit is the state permit a business needs before it builds or runs equipment that releases pollution, such as diesel backup generators. A Title V permit is the federal operating permit for the largest polluters. The two water permits are the National Pollutant Discharge Elimination System permit and the Water Pollution Control Facility permit. Governor’s letter
Applications already on file are caught, because the letter pauses the processing of applications and not only new filings. Cities are caught too. The letter pauses requests from cities to renew or change their wastewater treatment plant permits so the plants can take in data center wastewater. One AI data center already in line is an Amazon project in Boardman whose air permit is under review. Capital Chronicle The developer of an AI data center in Salem says the pause will not affect its current step. Salem Reporter
The letter’s request covers new or expanded facilities, but its list of permits refers only to new facilities. That leaves some doubt about expansions.
| What the letter changes | Before October 9 | After the letter |
|---|---|---|
| Air permit for a new site | The agency reviews and issues it if rules are met | Processing stops until July 1, 2027 |
| Applications already filed | Review continues on the normal schedule | Review is paused |
| City wastewater plant permits for data center flows | Processed like any renewal or change | Paused |
| Water discharge permits for a new site | Reviewed and issued normally | Processing stops until July 1, 2027 |
How Oregon’s air permit law applies to a paused permit
Oregon law bars anyone from building or running a source that needs an air permit without first getting that permit. ORS 468A A paused permit therefore means a stopped project. The same chapter also sets a clock. When the state has asked for construction plans and then fails to issue an order within 60 days of receiving them, that silence counts as approval to build unless federal law forbids it. The letter does not say how a pause fits with this 60 day rule.
Title V permits carry a second limit. The statute requires Oregon’s Title V rules to guard against unreasonable delays, as the federal Clean Air Act demands. ORS 468A An agency official told the advisory committee in July that the agency can deny an air permit only when the applicant cannot show it meets state and federal rules. DCAC summary State law gives a right to a hearing against an order, and the letter does not say whether a pause counts as one.
Existing sites that are not expanding are in a different position. The agency’s rules keep a permit in force when the holder files a timely renewal, until the agency acts on it. OAR 340 Division 216 The letter does not mention renewals for unchanged sites.
Permit offices the letter does not address
The letter is addressed only to the state agency. In Lane County, the Lane Regional Air Protection Agency runs the air permit program under the same state rules. OAR 340 Division 216 A former Clean Water Services executive spoke with the Hillsboro Herald. The executive said the Washington County sewer agency issues its own discharge permits to businesses and would not be stopped by the letter. Hillsboro Herald Neither body is named in the governor’s request.
The advisory committee’s preliminary report is open for public comment until 5 p.m. on October 24. Capital Chronicle The Legislature next meets in January, and the pause runs until July 1, 2027.
