r <br />LTJ <br />Construction & Demolition/Inert Debris Facility Report <br />Tracy Materia/ Recovery and Transfer Facility <br />30703 5. MacArthur Drive, Tracy, California 95377 <br />Proposed Activity — Inert Debris Recycling Operations and C&D Operations <br />Expansion <br />Phase 1: Inert Debris Recycling Operations <br />Tracy MRF & TS will accept an annual average of 150 TPD of source -separated <br />Type A inert debris, and a peak of 200 TPD of source -separated Type A inert <br />debris collected and delivered to the facility by affiliated companies, Tracy <br />Disposal and Delta Disposal, and other commercial vehicles. Self -haul vehicles <br />from the general public will also utilize the operations. All materials are closely <br />evaluated and controlled at the point of generation to assure minimal <br />contamination. The Type A inert debris, as defined herein and by state <br />regulations, is primarily collected from demolition sites. This operational area of <br />the site will not accept any mixed construction and demolition debris, shingles, <br />green waste, or any other types of wastes or materials other than clean inert <br />debris. <br />Materials are delivered to the facility in debris box trucks, end dumps, dump <br />trucks, and other commercially licensed vehicles. There will be at least one full <br />time site attendant during the operating hours. Vehicles are weighed at the scale, <br />and routinely weighed during exiting the facility to validate tare weights. Vehicle <br />tare weights for regular trucks are stored in the scale computer control system for <br />immediate assessment. These vehicles with existing tare weights are not <br />required to stop at the scale when they leave the site. <br />Trucks and debris boxes containing inert (Type A) debris will be dumped in either <br />of the inert operations areas. C&D debris and reject materials, such as rebar and <br />other loose debris that comprise of less than 1% of the inert material, are <br />separated out by both machine and hand processing and removed from the <br />processing area. The rebar metal is placed in a roll -off bin adjacent to the inert <br />stockpiles and taken to the MRF building, consolidated with other recovered <br />metals, and transported to a nearby metal recycler when bin is full. <br />Each of the operations/inert stockpile areas is designed to allow operator <br />flexibility in the recycling activity; each may consist of both pre-processed and <br />processed materials whose proportions will vary dependent on the amounts of <br />incoming materials, the rate at which materials are processed, and the demand <br />for aggregate base rock. The Type A inert debris is stockpiled at either of the <br />inert operations areas at the northwest corner of the site, as shown on the site <br />plan. The total onsite storage of the inert stockpiles is approximately 30,000 <br />cubic yards. <br />When a sufficient stockpile is created for efficient crushing operation, the <br />concrete is crushed by a portable, trailer -mounted grinder and placed on a <br />portion of the Operations Area/Inert Stockpile awaiting removal from the site by <br />® truck for use as an aggregate base material for road and other construction <br />3 170.18 CDI FacReport 050813 revised <br />
