Document Description
Aemetis Biogas LLC, in coordination with Stanislaus County Public Works, is proposing to construct approximately 32.5 miles of dairy biogas pipeline located in unincorporated Stanislaus and Merced Counties. The pipeline would provide transmission of biogas collected from seventeen privately owned dairy farms using a covered anaerobic lagoon digester, which would then be pressurized for transmission to a central Biogas Cleanup Plant co-located at the Aemetis Advanced Fuels Keyes ethanol production facility. The pipeline would be up to eight inches in diameter carrying pressurized methane and CO2 based biogas, and would be installed a minimum of four feet below existing ground level. The proposed pipeline would be constructed within the existing Stanislaus and Merced County roadway right-of-way and would include an operation, access. and maintenance easement and indemnification agreement within that facility. In some select locations, the pipeline would be constructed on private agricultural properties.
