In June 2019, Oregon state regulators approved an expansion of Threemile Canyon Farms’ facility, and Threemile Canyon installed new equipment to purify the methane from its digester.

Threemile Canyon Farms is Oregon’s largest dairy with 68,340 cattle, including 33,000 milking cows. In 2012, the farm built an anaerobic digester to capture methane emissions from all that manure. It has since used the gas to generate electricity, which it sells to the interstate utility PacifiCorp.

With the new purifying expansion, farm managers now plan to inject the methane into a nearby natural gas pipeline, which will transport it to southern California to produce cleaner-burning fuel for trucks. | READ MORE
