Proposed Odor Impact Minimization Plan — Compost Facility Tracy Material Recovery Facility and Transfer Station 30703 S. Mac4rthur Drive, Tracy, California 95377 operate equipment until the employee has demonstrated that he or she is competent to operate that equipment. Annual review and training ensuring continued safe operations of the facility and compliance with regulations will be conducted. Utility service interruptions: • Electric and Gas: critical on-site equipment is diesel -powered and not subject to local power failures. • Water: with the installation of a 150,000 gallon water storage tank with an emergency pump capable of pumping 1,200 gallons per minute and an active onsite well, the facility is self-sufficient in its water needs. • Telephone: the office staff and the key employees on site utilize cellular telephones and/or radios to communicate and coordinate their daily and routine operating practices. Section 17863.4 (b) (5) - Operational Considerations and Procedures to Minimize Odors. Odor Control: The compost industry has proven that with proper management techniques and use of appropriate tools, offensive and nuisance odors can be controlled. Odor emissions from the green material and co -collected food waste feedstock will be minimized through proper management of the windrows and storage piles in terms of time, temperature, moisture, turning to maintain aerobic conditions, and proper carbon -to -nitrogen (C:N) ratio to reduce ammonia levels. The consistent monitoring of the active compost will maximize the aerobic decomposition. Maintenance of the optimum moisture content and application of water will enhance and expedite aerobic decomposition and minimize odor emissions. CTI System Operational practices are key contributors to effective odor control for the enclosed aerated static pile composting (CTI System). Thorough inspections of incoming loads coupled with prompt blending of yard and organic wastes, plus rapid movement of feedstock from the CTI feedstock processing/mixing area into the fully enclosed composting bags are all essential operating steps. Under normal operations, wastes will be processed into bags within 48 hours of receipt. • Bagging The feedstock is placed into a bagging machine that fills an elongated thermoplastic 8 -mil laminated plastic composting bag and installs two air vent pipes to assist aerobic decomposition. The entire composting process will take place inside of the elongated thermoplastic bag. The bags are 12 feet in diameter and approximately 185 feet in length and can contain up to 350 tons of feedstock. The bagger is fed from a truck or loader onto a feed table, conveyor or into a hopper, which feeds material to the compaction unit on the bagger. Compaction pressure is controlled by adjusting the breaking 15
