TRACY MATERIALS RECOVERY &TRANSFER FACILITY RFI AMENDMENT NO. 3 Tracy Material Recovery and Transfer Station is committed to work with the LEA on the current and future RFI Amendments while discussing plans to revise the Solid Waste Facility Permit during 2006 and 2007. RFI AMENDMENT NO. 3 FORMAT: RFI Amendment No. 3 is presented as a stand alone document that is presented as Appendix H to the RFI dated December 1993. Tracy Material Recovery and Transfer Station (TIVIR/TS) are committed to prepare a completely new Transfer/Processing Report (TPR) and Report of Composting Site Information (RCSI) as part of the Solid Waste Facility Permit Revision process in 2007. INERT STORAGE AND PROCESSING OPERATION: Figure 3 — Preliminary Site Plan has been amended to show the Inert Processing Area just west of the compost pad along the access road to the northwest area of the facility. The size of the pad is 50 feet wide and 200 feet long and does not exceed 20 feet in height with 1:1 side slopes. The total volume of the inert stockpile will not exceed 4,000 cubic yards at any one time. The inert piles will be surrounded by a dirt berm on the south and east sides to prevent inerts from inadvertently failing (See attached Map). The west side will be up against the existing cut slope. The north side will be open for access. The inert 0 piles will not exceed 1:1 slope less than the angle of repose for stockpiled inerts on the three sides that are dirt bermed. On the open north side, the inerts will be sloped at 2:1 for a safety factor should equipment or workers be nearby. With the angles of repose at 2:1 and dirt berming around the other edges, the potential of falling inerts is prevented. Recent regulations adopted by the California Integrated Waste Management Board in August 2003 have state minimum standards for the storage and processing on inert materials. TMR/TS will conduct operations in a manner that could conceiving be an exempt activity from any state minimum standards should the activity be sited away from the current Solid Waste Facility Permit permitted boundary by only receiving Type A material and with storage of less than 6 months and with finished products on-site for less than 18 months. Because the activity is within the permit boundaries of the SWFP, this RFI Amendment is being filed for the inert storage and processing area. Material Types: Materials delivered to the inert processing and storage operations are source separated and separated for reuse Type A inert material only, are <10% residual material, contain <1% putrescible material, and are separated at the point of generation. Inert (Type A) Debris includes specific clean inert material including but is not limited to concrete (including fiberglass or steel reinforcing bar embedded in the concrete), fully cured asphalt, brick, slag, ceramics, plaster, clay and clay products.
