Document Description
Site Approval application to install a manure only digester and biogas facility on an 8.5-acre portion of a 444.68-acre parcel with an existing dairy, the Douma Dairy. The digester processes manure waste through a gas collection and water filtration system to convert greenhouse gases (GHG) to Renewable Natural Gas (RNG) and to convert filtration by-products to fertilizer. The components of the proposed project include a digester system, 3 natural gas gensets, 2 Livestock Water Recycling systems, backup/emergency flare, biogas upgrading equipment, fire suppression water supply tank, and a 1,500-square-foot utility/maintenance shop. The digester will process manure from the onsite dairy and from a second dairy under the same ownership located 25.5 miles east of the project site in Stanislaus County. It is estimated there will be 11 daily supply trips from the offsite dairy. The RNG will be trucked away an estimated 7 days per week. The resulting separated solids from the project will be sold as fertilizer and trucked offsite 2 times daily. The parcel will be served by an on-site water well, a septic system for waste water disposal, and natural storm drainage. The facility proposes to operate 24 hours per day, 7 days per week with 14 truck trips per day, an additional 3 truck trips per week, and 1 employee arriving on site in a personal vehicle during normal daytime business hours 8 am to 5 pm, 5 days a week, as well as a maintenance truck onsite once per week. The project site has an existing access driveway on S. Kasson Road. (Use Types: Agricultural Waste; Utility Services - Major).
