Amazon (AWS) campus, Gar Swanson Road, Morrow County
A four-building Amazon campus on about 102 acres, with a DEQ air permit for 112 emergency generators, whose utility supply was capped at 40 MW in 2023 and which proposed gas fuel cells to fill the gap. Also known as: PDX109.
Who is behind it
The record, newest first
A news report said an Aug. 19 DEQ letter cited a fire pump that ran over 55 hours straight here on Dec. 15, 2023, during construction; the $10,400 penalty also covered Hermiston water permit matters. (Apple Valley News Now, Sept. 30, 2025)
DEQ opened comment through April 24 on swapping one diesel backup generator with no rise in emission limits; the permit was set to expire Aug. 1, 2026. (East Oregonian, March 27, 2025)
An updated assessment described four buildings of about 220 by 1,000 feet on roughly 102 acres, with the campus still being built and the fuel cells tied to regional transmission upgrades such as Boardman to Hemingway. (Oregon Department of Environmental Quality (Maul Foster & Alongi for Amazon Data Services), Sept. 14, 2023)
Amazon's consultant told DEQ the first data center was complete and others were being built, and proposed about 24 MW of Bloom natural gas fuel cells for around six years because the cooperative could deliver only 40 MW. (Oregon Department of Environmental Quality (Maul Foster & Alongi for Amazon Data Services), June 7, 2023)
DEQ issued standard air permit 25-0062-ST-01 for the site, covering 112 emergency diesel generators of about 266 MW in total. (Oregon Department of Environmental Quality (Maul Foster & Alongi for Amazon Data Services), Sept. 14, 2023; Oregon Department of Environmental Quality (Maul Foster & Alongi for Amazon Data Services), June 7, 2023)

The full record
- Status note
- Consultant filings with DEQ said the first building was finished by June 2023 and later ones were being built; a September 2023 filing still called the campus under construction. In March 2025 DEQ was changing the facility's permit. How many buildings now run was not found.
- Power note
- No facility load is stated. The DEQ permit authorizes 112 emergency diesel generators of about 266 MW in total, which is backup capacity; the utility limited the site to 40 MW in 2023.
