Title

Conditional Use Permit 2024-004, Carriere/Syntech CF1, LLC Advanced Thermal Conversion

Description

Conditional Use Permit 2024-004, Carriere/Syntech CF1, LLC Advanced Thermal Conversion (ATC) project will operate on a 24/7 basis to remediate up to 135,000 tons a year of waste walnut shells (WWS) from an existing onsite walnut shelling facility into approximately 1,041,000 MMBtu/year of Renewable Natural Gas (RNG), which will then be compressed into a mobile storage trailer and then transported an existing walnut huller/dryer facility to be injected into a PG&E pipeline. The RNG project, referred to as SynTech CF1 will consist of the following four main operational components: 1. Organic Feedstock to Syngas Conversion 2. Biochar Transfer and Storage Facility 3. Collection of Syngas and Upgrade to Pipeline Quality RNG 4. Pipeline RNG Storage and Transfer Facility Walnut shells will be moved to the ATC site via an enclosed conveyor system to a secondary waste walnut shell storage building used specifically for the ATC process. The project will draw power from the local utility grid during normal operation. In the case of grid power interruption, a natural gas and/or syngas fueled emergency generator will power essential safety and operational systems until grid power is restored. The biochar byproduct of the ATC process will be approximately 4% by volume of the WWS volume converted or remediated in the process and will be collected in 500 lb. storage containers for storage and shipment.
