• Two portal buildings (1,080 square feet each) that will be essentially truss structures with metal wall �. panels that contain lights, cameras, and sensors used to assist gate employees in the inspection of chassis and containers as trucks drive through the open ends of the portal. • Crew shanty (280 square feet) that will be used as a combination weather protection, office workspace, lunch room, and coordination area for Union Pacific yard crews in remote areas of the facility. • Mechanical Forces Building (2,000 square feet) that will be used by crews working at the inspection pit where switching locomotives are serviced. The building will include a bathroom and a crew room with tables for lunch and breaks. In addition to the buildings, six new canopies are proposed: • Two Truck Canopies (3,360 square feet each) that will provide shade and some protection from inclement weather for drivers as they are processed into and out of the facility at the gates. • IWTP Sludge Container Canopy (890 square feet) to prevent rain from falling in the sludge drying area. • Inspection Pit Canopy (6,270 square feet) that will provide shade and some protection from inclement weather for crews working at the inspection pit. • Roadability Canopy (9,400 square feet)that will provide shade and some protection from inclement weather for crews working at the inspection pit. • Passenger Shelter Canopy (200 square feet) that will provide shade and shelter for passengers of incoming trucks, since Union Pacific security protocol permits only the driver of the truck to enter the facility. Services Approximately 70 percent of the existing facility is paved with concrete, with a system of open channels and enclosed pipes to convey storm water runoff to several on-site detention and retention basins. These basins attenuate or detain site runoff before ultimate discharge to the French Camp Outlet Canal (FCOC)which is owned and maintained by the South San Joaquin Irrigation District (SSJID). The existing drainage agreement between SSJID and Union Pacific does not allow for increased flows that may be caused by an expansion of the facility. Therefore, the applicant proposes to use retention facilities and infiltration to eliminate any discharge into the FCOC from the intermodal expansion area. A system of culverts, enclosed pipes, and open channels will be developed to convey runoff to one of several on-site retention basins. Runoff from proposed maintenance areas may contain oil or grease. This runoff will therefore be directed to an on-site IWTP. The IWTP will then treat the runoff and discharge the treated effluent to a lined evaporation basin. Petroleum and sediments collected at the IWTP will be disposed of off-site at approved locations. Water will continue to be provided via an existing 12-inch water main constructed by Union Pacific in 1993. The water main was later dedicated to the City of Lathrop for incorporation into its water system. Wastewater from the facility is currently treated by one septic system and leach field that are located directly south of the existing maintenance building. This system serves the current gate and maintenance buildings. The two buildings will be relocated and the septic system will also be relocated to serve the San Joaquin County PA-0900184 & 185\Union Pacific `, Community Development Page 3
