Report of Composting Site Information Tracy Material Recovery Facility and Transfer Station 30703 S. MacAurthur Drive, Tracy, Ca. 95377 Excluded Materials Materials other than those described are excluded from the site. There are no plans to process hazardous waste or wastewater treatment waste streams on the site at this time. The composting of unprocessed mammalian tissue, including but not limited to, flesh, organs, hide, blood and morrow is expressly prohibited, except when from the food service industry, grocery stores, or residential food scrap collection programs. The composting of medical wastes is expressly prohibited. Special Occurrence Loq 14 CCR §17869(b) requires the compost operator to maintain general record keeping for special occurrences. A special occurrences log will be maintained at the facility. The log will include the following special occurrences or information: fires, flooding, earth movement, unusual and sudden settlement, injury or property damage accidents, explosions, discharge of hazardous or other unacceptable materials, disposition of material exceeding established limits, or other unusual occurrences. A site operations log comprising all safety, production, load checking, monitoring, and public complaints will be maintained. These logs will be kept at the Site Office. The Site Manager is responsible for maintaining these records. He is also responsible to see that records are available to the appropriate regulatory agencies. Composting • Green Material, andCo-collected Yard and Green waste Co-collected yard waste and green waste (maximum 20% food waste) may be composted in traditional, open windrows. The windrows may be up to 8 feet in height, 20 feet in width and vary in length from 350 to 500 feet. • Composted Digestate Anaerobic digestion digestate that has already undergone several days of in-vessel composting prior to delivery to the Tracy MRF/TS and CF may be composted in windrows if there are not odor problems. If the already composted digestate does produce an odor problem then it will be placed in the aerated static pile system. Tracy MRF/TS and CF will keep the windrowed material at a temperature between 131 and 160 degrees Fahrenheit for a fifteen-day period, turning the windrows a minimum of five times throughout those fifteen days in order to reduce pathogens. Each day during the pathogen reduction period, at least one temperature reading will be taken a minimum of every 150 feet of windrow and the temperatures will be taken 12 to 24 inches below the pile surface. Tracy MRF/TS and CF will keep accurate records of the fifteen-day pathogen reduction period, plus all other temperature records, until each windrow reduces to a temperature below 131 degrees Fahrenheit. The temperature records will be stored at the onsite office. After the fifteen-day pathogen reduction period, Tracy MRF/TS and CF will continue to turn the windrows as needed, approximately every three to seven days; the composting time will typically take two to three months. Tracy MRF/TS and CF will also conduct temperature monitoring on all 20
