X. FACILITY rZANSFER OPERATIONS [112.7(e)(3)] Underground pipeli es transfer oil products to several areas throughout the yard. Underground pipe associated with the separation plant in Area 2 include a drainage system from the diesel shop building (Q), wash rack, and fueli ig rack (M) to the separation plant. Oil is pumped between the waste oil pump (B) and the waste oil tan(No. 9) and sludge is transferred by an underground pipeline from the sludge pump (D) to the sludge to d spot (E). Underground pipelines associated with the oil separation plant are steel pipe with Extru-Coa plastic coating. The underground pi elines transferring oil in the diesel storage area, Area 3, include lines from the pump skids (J and L) to T#nk No. 6 and from Tank No. 6 to the fueling racks (M) in Area 4. These fuel lines are cathodically prot cted as well as being coated with Extru-Coat plastic protective wrapping. Journal box oil and it compressor oil are transferred from reusable totes to the journal box oil load area and service pit (N). Cast iron, transit, and clay pipelines transfer waste water and oil to the drain sump (T) north of the diesel shop area. Piping fro n the sump to the separation plant in Area 2 is steel with Extru-Coat plastic coating. Lube oil is transfen ed from the lube oil tank (No. 11) to the fueling rack (M). Drained lube oil is transferred to the usc d lube oil tank (No. 12) through steel lines with Extru-Coat plastic coating. High pressure testinwas performed during the last quarter of 1994 on the diesel fuel piping system. Pressure testing con fists of pressurizing the pipes to 100 pounds per square inch (psi) for 15 minutes. Aboveground piping is used to supply fuel to Tank No. 6 in Area 3. This piping and other aboveground piping and associated visible transfer operation components are visually observed approximately weekly by UPRR personnel. When underground ipeline sections are exposed, they are examined and corrective action taken if evidence of corrosion is observed. Pipeline terminal connections are capped or blank flanged if the pipeline is determined to be out of service. Aboveground pipink is painted. Aboveground pipe supports are designed to allow expansion and contraction. XI. FACILITY TANK CAR AND TANK TRUCK LOADING/UNLOADING [112.7(e)(4)] Several load and to tank cars on the sl track is either contai the separation plant. of the sludge tank (T facilities are located within the yard. These facilities are described below. Sludge collected in the separation plant is pumped through the sludge load spots ge load track (F). Drainage in the area of the sludge load spot and the sludge load I in local topographic lows or flows into drain grates along the track and back to iximum spill from the sludge loading process would be 3,000 gallons, the volume 3).
