Z-Best Composting Facility Modifications Project
Document Type
NOP - Notice of Preperation

Document Description
The proposed project site is the existing Z-Best Composting Facility at 980 Highway 25, which currently operates under a County-issued Use Permit. The proposed project includes modification of Z-Best's existing composting process from the current windrow method to an aerated static pile process, and associated changes in operations and site design. The proposed new composting process would occur within the already developed area of the existing composting facility. The proposed new process would result in a throughput increase from the current max of 1,500 tons to 2,750 tons per day, which would require an additional 59 trucks per day. The project proponent has proposed that the increased truck trips be confined to the hours of 8 pm to 4 am.
