Project Description Tracy Material Recovery Facility and Transfer Station Expansion 30703 S. Mac*thur Drive, Tracy, Califomia 95377 a.► Table 11 Current Baseline and Proposed Operation for Biomass Wood Chips Current System—Baseline Proposed Biomass Gasification Unit Fuel Source Processed clean wood chips from permitted facilities that remove treated wood waste and other contaminants. Fuel Supply 40 tons per day of clean wood chips from on-site wood waste recovered from the mixed C&D Processing Facility and wood waste processing area. Technology Large biomass energy facilities from On-Site gasification technologies with the mid-1980 are in the California greater efficiencies from 30% to 75% Central Valley that utilizes an with cogeneration. upgraded steam-turbine cycle with 20%efficiency.

The applicant proposes to add a biomass gasification unit to produce green electricity out of the clean processed wood waste materials that are currently recovered and processed on-site. The applicant proposes to utilize 40 tons per day (TPD) of clean wood chips processed on-site to generate approximately 1 mega-watt/hour of electricity. The biomass gasification unit will only receive clean processed wood chips, and a similar unit has already obtained the necessary air permits from the San Joaquin Valley Air Pollution Control District.
