QUINCY — Air quality is being monitored around the Lamb Weston processing facility in Quincy, 1005 E St. SW, following the release of anhydrous ammonia at the plant Sunday.

“There were no injuries associated with the leak,” wrote Shelby Stoolman, Lamb Weston communications and external relations, in an email to the Herald.

The leak was reported Sunday afternoon, Stoolman said.

“It was not a planned release, but it has been contained in the facility since it happened,” said Lexi Smith, communications coordinator for the Grant County Health District.

“We have shut down one production line impacted by the release and are investigating the exact cause,” Stoolman wrote.

Smith said there is no threat to the public currently. The facility is being ventilated and that’s being monitored by Lamb Weston crews and the Washington Department of Ecology.

“They’re still working on the ventilation process and we’ll have air monitoring teams on site until that process is complete,” Smith said. “The DOE has been on site since yesterday evening,”

“We are working with the proper authorities to assess the release and ensure safety for our team members as well as public safety,” Stoolman wrote.

Anhydrous ammonia is used in the facility’s refrigeration system, she wrote.
