The record, newest first

  2. The Hermiston Herald reported DEQ taking comment on a proposed air permit for PDX194, a new Amazon data center at 80939 Powerline Road, Hermiston, after a Cleaner Air Oregon risk assessment. (Hermiston Herald, April 16, 2024)

  3. Umatilla's council agenda carried first amendments to the PDX 194 and PDX 260 agreements, both on Powerline Road, revising the property descriptions and clarifying how future bond money is handled. (City of Umatilla, March 7, 2023)

Conflicts and open questions

  • The published PDX194 address and the reporting place the site at or near Hermiston, while the agreements are with the City of Umatilla. No record opened says which city's limits, if any, include the site.
  • County minutes do not name Powerline Road or the PDX numbers; matching their two Greater Umatilla orders to these sites is inferred from the October 2022 date in the city packet.
  • The map point is approximate; the address was not geocoded.
