<br /> adjacent CenterPoint Properties Intermodal Center, removing all of these truck trips from the local roads. Finally,
<br /> within 5 to 10 years, an expanded facility would remove approximately 130,000 long-haul truck shipments originating
<br /> from the Central Valley from regional highways to lower-cost, lower-emission rail transport. Therefore, regional, long-
<br /> haul truck traffic may actually decrease as a result of the facility expansion, with corresponding lower fuel emissions
<br /> and highway maintenance costs, subject to further study in the EIR for the project,
<br /> Structures
<br /> Buildings constructed as part of the expansion include eight new structures,two of which (gate building &
<br /> maintenance building)will be replacing the existing buildings of the same name.The new building area will total
<br /> approximately 24,042SF.These structures(see Tables 2 &3) include the following new'buildings:gate building,
<br /> maintenance building, Industrial Wastewater Treatment Plant(IWTP), driver kiosk,two portal buildings, and a crew
<br /> shanty.The uses and descriptions of the gate and maintenance building do not significantly differ from the existing
<br /> gate&maintenance buildings; however Union Pacific fully intends to incorporate LEER design principles in the
<br /> design of the new gate building. New buildings that do not currently exist on the site include the following:
<br /> 1. Driver Kiosk—An approximately 350 SF building that serves as an information station for truck drivers. The
<br /> room. Drivers who are in need of assistance from the
<br /> kiosk includes a phone,vending machine, and a rest
<br /> Union Pacific gate building employees or their transportation company may use the phone to call either a
<br /> clerk in the gate building or their employer.
<br /> 2. Portal Buildings—The 1,080 SF portal buildings are essentially truss structures with metal wall panels which
<br /> contain lights, cameras, and sensors that are used to assist gate employees in the inspection of the chassis,
<br /> container, and container contents as trucks drive through the open ends of the portal.
<br /> 3, Crew Shanty—A 280 SF building used as a combination weather protection,office workspace, lunch room,
<br /> and coordination area for Union Pacific yard crews in remote areas of the terminal.
<br /> 4. IWTP—The 100 SF IWTP building houses the electrical&control components for the various IWTP
<br /> equipment such as pumps, oil-water separators,etc., as well as operations manuals.
<br /> In addition to the new buildings,the existing 120'tall wireless communications tower will be replaced by a new, 140'
<br /> tall tower. The tower will be a freestanding lattice structure, similar to the existing tower.The tower will provide for in-
<br /> yard communication between the gate building and truck drivers, and communication between yard personnel and
<br /> incoming trains.This tower is essential to the operations of the yard.
<br /> Onsite Drainage
<br /> Much of the facility will be paved at full build-out. Additional runoff will be created by the addition of impervious
<br /> surfaces such as concrete,asphalt, and building roofs.A system of culverts, enclosed pipe systems, and open
<br /> channels will be used to convey runoff to one of several onsite detention or retention basins. Retention basins will
<br /> meet County design requirements. Detention basins would provide for terminal drainage to the French Camp Outlet
<br /> Canal.
<br /> Industrial Stormwater Runoff Treatment
<br /> Runoff from maintenance areas which are likely to contain oil or grease will be directed to an on-site Industrial
<br /> Wastewater Treatment Plant(IWTP). These areas include maintenance areas, wash areas,fueling areas, and the
<br /> diesel locomotive maintenance area. Process wastewater from the maintenance building will also be routed to the
<br /> IWTP. The IWTP will treat the runoff and discharge the treated effluent either to a public sanitary sewer main or to an
<br /> evaporation basin. The IWTP building and equipment are routinely used at Union Pacific Yards across the country,
<br /> and are adapted to meet local standards and regulations. In addition to this treatment control Best Management
<br /> Practice(BMP), source control BMPs are routinely incorporated into Union Pacific facility designs and work
<br /> procedures, including, but not limited to, spill prevention and clean-up processes, properly designed vehicle and
<br /> equipment fueling and repair areas, and prevention of non-stormwater discharges. Collected petroleum and
<br /> sediments will be disposed of offsite at approved locations,
