Aemetis, Inc. announced receipt of the Authority to Construct (ATC) air permits for its planned sustainable aviation fuel (SAF) and renewable diesel (RD) production plant in Riverbank, California. The plant is designed to produce 90 million gallons per year when allocating 50% to SAF and 50% to renewable diesel production, and 78 million gallons per year when allocating 100% of production to SAF for the aviation market. The Authority to Construct permits were issued by the San Joaquin Valley Air Pollution Control District following an extensive technical review and two public comment periods.

In September 2023, Aemetis received approval from the City of Riverbank for the Use Permit and California Environmental Quality Act (CEQA) review after a separate technical review and public comment process. Together, these permits are the key permits needed for Aemetis to proceed with engineering and financing to construct the plant. The 125-acre Riverbank Industrial Complex has 100% renewable hydroelectricity; a rail line and storage for 120 railcars; 710,000 square feet of buildings; and 50 acres of developable industrial land.

An agreement for the lease/sale of the Riverbank Industrial Complex to a subsidiary of Aemetis was signed in December 2021.
