The Mill Valley Project

About the project

The Mill Valley renewable natural gas (RNG) project in Milbank, South Dakota, includes building two new anaerobic digesters on Mill Valley Farm in Allegan County. The manure from this farm will produce renewable natural gas each year. After the project is complete, the biogas generated by this manure will be captured, cleaned, and converted into RNG. Mill Valley is part of the third tranche of projects developed under the Brightmark RNG Holdings LLC joint venture with Chevron U.S.A. Inc.

WASTE TO NEW PRODUCTS

The facility will generate renewable natural gas annually. Other renewable products generated by the project include fertilizer.

“As dairy farmers, we can be part of the solution in helping the environment. The digester projects are a win-win because we can further process the manure while reducing greenhouse gasses. Agriculture continually evolves. Our improvements in sustainability in the last generation are just short of incredible. Unfortunately, we don’t often tell our stories. We are looking forward to partnering with Brightmark to bring these next-generation projects to South Dakota.”

– Lynn Boadwine, Owner of Boadwine Dairy, Inc. and Mill Valley Dairy

Partners

In October 2020, Brightmark LLC and Chevron U.S.A. Inc. originally announced the formation of the Brightmark RNG Holdings LLC joint venture to own projects across the United States to produce and market dairy biomethane, a renewable natural gas. Equity investments by each company in the new venture fund construction of infrastructure and commercial operation of dairy biomethane projects in multiple states. Chevron purchases RNG produced from these projects and markets the volumes for use in vehicles operating on compressed natural gas.
