Except for the wood storage and composting activities, nearly all of the on-site operations will be
<br />conducted indoors. This includes maintenance of TMRF vehicles as well as the tipping of refuse from
<br />refuse collection vehicles, sorting of recyclables, and the processing of solid waste that cannot be
<br />recycled for transfer to the landfill. An administration and maintenance building is proposed at the
<br />extreme southern end of the site which will house offices as well as vehicle maintenance facilities. Another
<br />building, shown on the site plan as the transfer station, initially planned to contain approximately 40,000
<br />square feet, is proposed to be constructed within the southern portion of the 30 -foot -deep pit on the site.
<br />This structure will house the tipping floor, sorting area and lines, processing and load -out areas, and a
<br />refuse transfer area. The applicants anticipate that this building may ultimately be expanded to the north
<br />and west to accommodate additional volume in the future. This building will be approximately 35 feet tall
<br />Iand constructed with a concrete slab floor with metal siding and roof.
<br />Parking for employees and visitors will be located adjacent to the proposed administration and
<br />maintenance building, located at the southern end of the site, and out of the reclaimed gravel pit, where
<br />the actual refuse operations will be conducted. Parking areas, a truck wash, and a fueling station for
<br />company trucks and equipment will be constructed in the center portion of the reclaimed gravel pit.
<br />Driveways and parking and maneuvering areas will be surfaced with asphalt or concrete. Access to the
<br />site is via a driveway off of MacArthur Drive located at the northern end of the site. Commercial vehicles
<br />and self -haul vehicles will pass by a gatehouse, located midway along the driveway, prior to arrival at the
<br />transfer station. At that point, commercial vehicles will be weighed, and private self -haul vehicles will have
<br />their loads checked and be charged a vehicle fee. This gatehouse is located far enough off of MacArthur
<br />Drive and the access driveway is long enough to accommodate any vehicles waiting to access the facility
<br />without having traffic backed up onto MacArthur Drive.
<br />There are no off-site drainage facilities. Drainage facilities on the site will consist of the following.
<br />General Storm Water Runoff
<br />Storm water runoff from all areas except the wood storage and yard waste composting area will
<br />drain to an on-site retention pond. Runoff will be collected via surface swales and ditches and
<br />an underground storm drainage system. The storm drainage system will be designed for the 10 -
<br />year storm per San Joaquin County Storm Drainage Design Standards. The retention pond will

<br />the south County to the Foothill or North County Landfills. Second, the materials recovery aspect of the
<br />project will aid the County and the City of Tracy in meeting the aggressive diversion requirements set forth
<br />in AB 939 of 25 percent by 1995 and 50 percent by the year 2000. These diversion requirements are
<br />expected to be met by a combination of hand sorting done on the tipping floor, mechanical sorting of
<br />selected loads, and composting at the TMRF, as well as other activities exclusive of this facility.
<br />TECHNICAL DESCRIPTION
<br />The proposed Tracy Materials Recovery and Transfer Facility (TMRF) will accept nonhazardous solid waste
<br />from the City of Tracy and the south San Joaquin County area. Recyclable materials will be extracted
<br />from the waste stream, and the residual waste will be transported to either of the two remote landfills in
<br />the County (North County or Foothill Landfills).
<br />It is estimated that, on average, the facility will ultimately receive approximately 800 tons of refuse per day,
<br />with occasional peaks of 1,000 tons per day. The amount actually received and processed through the
<br />TMRF may be less depending on the amount of separated yard and wood waste brought to the facility.
<br />The facility has been planned to accommodate projected growth in the south County area, both within
<br />the City of Tracy and surrounding unincorporated areas.
<br />Except for the wood storage and composting activities, nearly all of the on-site operations will be
<br />conducted indoors. This includes maintenance of TMRF vehicles as well as the tipping of refuse from
<br />refuse collection vehicles, sorting of recyclables, and the processing of solid waste that cannot be
<br />recycled for transfer to the landfill. An administration and maintenance building is proposed at the
<br />extreme southern end of the site which will house offices as well as vehicle maintenance facilities. Another
