Facility Capacity Study <br /> Tracy Material Recovery Facility and Transfer Station Expansion <br /> 30703 S. MacArthur Drive, Tracy, California 95377 <br /> _ C&D Facility Storage <br /> Mixed C&D debris that has been received will be processed within 15 days of receipt. <br /> Storage of unprocessed material will not exceed 15 days. Mixed C&D debris that has <br /> been processed and sorted for resale, or reuse, will not remain on site for more than 30 <br /> days. Market products will not be stored for more than 30 days. <br /> The total amount of material stored onsite will be limited by design constraints and will <br /> not exceed 25,640 cubic yards of C&D or wood debris at any given time (as noted in <br /> Table 4 below), although the facility could store up to 30 days x 820 TPD gate tonnage <br /> (98,400 cubic yards) as allowed by regulations. Please refer to Site Plan A2 in <br /> Appendix A. <br /> Table 4 <br /> Mixed C&D Debris Storage Volumes <br /> Storage of C&D Maximum Regulatory Design Capacity <br /> Allowed Capacity <br /> Gate Tonnage 820 TPD <br /> 30-day tonnage amount for 24,600 Tons <br /> maximum operations <br /> Maximum Storage of 24,600 Tons <br /> unprocessed and processed <br /> material <br /> Conversion at 500 pounds 98,400 Cubic Yards 26,540 Cubic Yards <br /> er cubicyard* <br /> 'Source:"Conversion Factor Study:In-Vehicle and In-Place waste Densities"CIWMB/CalRecovery, Inc.,April 1993 <br /> Storage piles will be limited in size to maintain worker safety and conform to the <br /> required fire control plan. Mixed C&D debris piles will not exceed 50 feet in width or 20 <br /> feet in height or 300 feet in length; this will allow for water or fire-retardant foam <br /> coverage by onsite firefighting equipment, which is continuously maintained and <br /> available, and keep the materials within reach of excavating equipment. Site personnel <br /> will be trained in fire recognition, firefighting and emergency procedures. Debris piles <br /> will be separated by a minimum 20 foot access area for heavy equipment, water trucks, <br /> and fire trucks or other firefighting equipment. <br /> C&D Processing/Wood Waste Area Capacity— 25,600 CYD <br /> Sheet A2 provides the proposed site layout and locations of the stockpiles. The C&D <br /> pad allows 12,900 CYD of mixed C&D material, where 3,500 CYD per day may be <br /> received, allowing up to 4 days of storage before processing. Since processing occurs <br /> Monday through Friday, there is adequate storage capacity for incoming materials. <br /> The proposed capacity for wood processing allows for up to 12,700 CYD of processed <br /> and/or unprocessed wood debris. The total storage capacity for the C&D Processing <br /> Area is 25,600 CYD. <br /> 6 <br />
