Morning traffic through Fairview hit a sudden standstill Monday after emergency crews rushed to a possible hazardous-materials incident at Townsend Farms and shut down a key stretch of Northeast Sandy Boulevard.
Gresham Fire and the Multnomah County Sheriff's Office were dispatched just after 7 a.m. to the 23400 block of Northeast Sandy Boulevard, where early scanner traffic and initial reports pointed to a potential ammonia leak at the facility. Hazmat teams moved in to secure the scene while investigators worked to confirm exactly what happened.
Officials clamp down on Sandy
Multnomah County announced the closure on X, posting, "We have closed Northeast Sandy Boulevard from Northeast 223rd Avenue to Northeast 238th Avenue to allow Gresham Fire to safely manage an incident. There is no estimated time for the roadway to reopen." Drivers heading through the Gresham-Fairview corridor suddenly found one of their main east-west routes blocked off.
Broadcastify scanner traffic captured first responders discussing "an active ammonia leak" at the site, according to KATU. Officials had not released a detailed incident summary at the time of reporting, leaving residents and commuters waiting on formal confirmation.
How hazmat crews tackle a call like this
Gresham Fire is leading the on-scene response, with the Multnomah County Sheriff's Office handling traffic control and perimeter security. In situations like this, hazmat teams typically isolate refrigeration and mechanical rooms, run air monitoring, and ventilate any affected areas before anyone is allowed back in.
That process can stretch on for hours, depending on the chemical involved and how much might have been released. Crews generally wait for clean detector readings and stable conditions before reopening roads or lifting any restrictions around the site.
Why ammonia raises red flags
Anhydrous ammonia is a workhorse chemical in cold-storage and food-processing operations, but it does not take much to cause trouble. The gas can trigger immediate respiratory irritation at low levels and more serious injuries at higher concentrations.
Federal guidance on how to handle anhydrous ammonia releases spells out specialized protective gear, careful air monitoring, and strict containment and ventilation procedures for safe cleanup, according to the EPA.
Townsend Farms’ footprint in Fairview
Townsend Farms operates processing and cold-storage facilities in the Fairview area, with state and federal records listing multiple locations along Sandy Boulevard and Townsend Way. Public records, including OSHA inspection details and Oregon Drinking Water Services listings, show the company with an operating presence at 23400 NE Townsend Way in Fairview.
Traffic headaches and neighborhood worries
The county’s closure of NE Sandy Boulevard between NE 223rd and NE 238th is expected to snarl morning commutes in and around Gresham and Fairview, and drivers are being urged to plan for delays and use alternate routes where they can.
Neighbors with respiratory issues or other sensitivities are being advised to track official announcements and follow any shelter-in-place or evacuation instructions that might come from Multnomah County or Gresham Fire as the situation develops.
This remains a developing story, and local outlets and county agencies are expected to release more information once responders fully secure the scene. KATU reported that a reporter was headed to the site for on-the-ground updates.
