The U.S. Department of Energy (DOE) is proposing to provide federal funding to Rialto Bioenergy Facility, LLC to validate unit processes and develop a project plan for the currently mothballed Rialto Bioenergy Facility, which would be redesigned to convert municipal solid waste into biogas. This NEPA determination is for Phase 1 Budget Period (BP) 1. Additional NEPA review will be required before proceeding with Phase 1 BP2 activities. If the recipient is selected to move forward into Phase 2, further NEPA review will be necessary once Phase 2 tasks are defined.

Phase 1 BP1 of the proposed project would be limited to data analysis and laboratory scale research/development (R&D). Office activities including reporting, design work, and grant management would take place at Anaergia Services, LLC in Carlsbad, CA and The Grant Farm in Sacramento, CA. Site visits to the Rialto Bioenergy Facility in Rialto, CA as well as other existing operational facilities would occur for the purpose of observing unit processes, but no physical work or new construction would take place at any site during Phase 1 BP1.
