TRA MATERIALS RECOVERY & TRANSFERWCILITY RFI AMENDMENT NO. 3 Operations: A front-end loader`will also periodically spread the inert material out'to allow the manual labor to remove the reject material from the interiorof the loads. C&D material and reject material are removed by hand from the exterior of the storage pile. The inert debris is also spread -out by the loader so that oversized pieces can be separated for pre-processing. Pre-processing involves breaking down the debris into pieces small enough to be accommodated by contracted crushing machinery. The concrete debris is stockpiled up to 4,000 cubic yard in 200 feet by 50 feet storage area not to exceed 6 months. When a sufficient stockpile is created for efficient crushing operation, the concrete is crushed by a contracted' portable, trailer -mounted grinder. Dust from materials handling is controlled with water spray from handheld hoses. The front-end loader also loads the inert material onto a slanted metal screen to remove fines and dirt from commingled loads of inert and dirt. The grill allows the fines to go through the screen, and allow the inert material to be screened off prior to transport off-site. Once concrete has completed crushing and screening process, it is stockpiled awaiting removal from the site by truck for use as an aggregate base material for roads and other construction projects. Stockpiles of finished materials do not exceed 20 feet in height. Inert debris that has been processed and sorted for resale, or reuse, will not remain on site for more than 18 months. Market products will not be stored for more than 18 months with some material being stockpiled on-site for future construction activity. Figure 3 — Preliminary Site Plan has been amended to show the construction & demolition (C&D) Debris Processing Area adjacent to the Transfer Station on the east side on the paced asphalt-concerte surface. The area is a quadrant of a semi -circle with an 80 feet radius comprising an operational area of approximately 5,000 square feet. Material will not exceed 4 feet in height and all material on the processing area will be removed at the end of each day. Bins full of recycled commodities need to be emptied within 48 hours of being full. The peak flow to this operational area would be 175 tons per day within the already permitted and allowable 1,000 tons per day. Recent regulations adopted by the California Integrated Waste Management Board in August 2003 have state minimum standards for the storage and processing on C&D materials.
