Connell Resources Timnath Pit Spill Prevention Control and Countermeasures Plan Revision Date: June 25, 2009 Section 18.0 Facility Transfer Operations, Pumping, And Facility Process [112.8(d)] Page 18-1 Section 18.0 Facility Transfer Operations, Pumping, And Facility Process [112.8(d)] The Facility has underground pipes as well as aboveground pipes used to transfer oils. 18.1 Buried Piping [112.8(d)(1)] The diesel Tank 1 has underground steel oil transfer pipelines to supply fuel to are protected with an induced rectifier system. If construction activities expose an underground pipe, it will be examined and if corrosion or deterioration is identified, corrective action will be taken Table 18.1: Buried Piping Protection Building or Area Name Material of Construction Protection Method Diesel Generator AST steel Induced Rectifer System 18.2 Terminal Connections [112.8(d)(2)] Out-of-service pipelines are evacuated and blank-flanged. 18.3 Pipe Supports [112.8(d)(3)] Pipe systems are adequately supported. Pipe supports are designed to minimize abrasion and corrosion and allow for expansion and contraction. 18.4 Inspections [112.8(d)(4)] Visual observations of valves, pipelines and pipe supports are made throughout the day by operations personnel. Aboveground pipelines and valves are also examined during the monthly assessment. The monthly assessment form is included in Appendix C. If buried pipe systems are modified, relocated or replaced, or new buried pipe systems are installed, Facility will conduct leak testing at the time of modification, relocation, replacement . or installation. 18.5 Vehicle Warnings [112.8(d)(5)] The pipe systems are protected from vehicular traffic Table 18.5 provides specific information on pipe protection from vehicular traffic.
