Oregon Air is a group of local residents who are impacted by the odors emanating from the composting operation at Grimm's Fuel in Tualatin, Oregon. In January 2026, we installed our first community air quality sensor in the Pony Ridge neighborhood to sample the air and collect real-time data. The sensor is now online!
We want to breathe clean air.
What's that smell? The odors from Grimm's compost have reached Sherwood, Tualatin, King City, Tigard, Wilsonville, Beaverton, and Portland, degrading our air quality, health, property values, and the livability of our neighborhoods. Dust from the facility impacts nearby residents and businesses. Grimm's facility has a long history of fires. We are requesting full mitigation of dust and odor.
