Blue Line Transfer, Inc. (Blue Line) proposed to develop an Anaerobic Digestion (AD) Facility (“the project”) that would be capable of processing 10,000 tons per year (tpy) of food waste and green waste into biogas that would be cleaned and converted into biogenic compressed natural gas (CNG). The project was expected to produce 56,000 diesel equivalent gallons (dge) per year of CNG, enough fuel for four to five CNG-fueled collection vehicles. RCH staff managed the Initial Study/Mitigated Negative Declaration (IS/MND) and prepared materials and assisted in the IS/MND public hearing before the City Council. RCH later reviewed proposed modifications to the Blue Line Biogenic CNG Facility project and determined that the modification would not change the conclusions or mitigation measures in the IS/MND. The modifications included increasing peak design capacity of the anaerobic digester facility from 10,000 to 11,200 tons per year. Another modification allowed the Biogas CNG station to connect to a PG&E natural gas line to blend PG&E natural gas with the biogas, which allowed the facility to refuel their entire CNG fleet on-site.
