MCMINNVILLE, Ore. (AP) — A fire and related ammonia in the air at the Organic Valley Creamery in McMinnville has prompted an evacuation order for everyone within a half mile of the business. KATU-TV reports McMinnville Police announced the evacuation at about 2:30 p.m. Tuesday because of ‘anhydrous ammonia’ being released as the fire burns. Police said people under evacuation should go to West Wortman Park. No injuries have been reported. The Centers for Disease Control and Prevention says anhydrous ammonia is a colorless gas with a pungent, suffocating odor.
