Organic Materials Composting Facility
Mesa County’s Organic Materials Composting Facility is the Western Slope’s trusted source for high-quality, nutrient-rich soil amendments and mulches. The Solid Waste Management Division utilizes specialized heavy equipment to transform yard waste such as grass clippings, leaves, and tree prunings into a US Composting Council-certified soil amendment for use in lawns, gardens, and in agriculture. Adding compost to your lawn and garden improves soil health and water retention, allowing roots and key microbes to thrive.
Contact information and hours of operation
Inclement weather closures
The safety of customers and employees is our number one priority. If the Compost Facility is deemed unsafe due to high winds or lightning, the facility will close. Conditions that generally cause an unsafe environment include:
- Sustained wind speeds of 25 miles per hour
- Gusts of 55 miles per hour
- Lightning within 10 miles of the landfill
During inclement weather closures, the site is continuously monitored, and safety conditions are assessed every hour. The Compost Facility will re-open when safety concerns have subsided.
In the event of high wind or lightning, call (970) 263-9319 to check on the closure status of the facility and associated waste disposal programs.
