2.1 Overview of the Proposed Project - Keystone XL pipeline - US ...

Draft Supplemental Environmental Impact StatementKeystone XL ProjectPipe storage sites would be required at 30- to 80-mile intervals and contractor yards would berequired at approximately 60-mile intervals. Each pipe storage site would occupy approximately30 to 40 acres and would typically be located close to railroad sidings and as close to theproposed route as possible. Typical rail sidings would be 20 acres in size and be at existing railsidings locations. Keystone would not be building any new rail sidings. Keystone would selectexisting commercial/industrial sites or sites that were used for construction of other projects aspreferred sites for the storage sites.Contractor yards would occupy approximately 30 acres. Suitable sites would need to be level,without structures, and not forested, and also would need to have a minimum of two safeingress/egress points on all-weather county roads rather than busier state highways for safetyreasons. Keystone would comply with all federal, state, and local requirements prior toconstruction. Where practicable, Keystone would seek out sites that have been previouslydisturbed. Keystone would work with landowners to obtain a temporary easement for use duringthe period of construction.Each pipe storage site would occupy approximately 30 to 40 acres and would typically belocated close to railroad sidings. Pipe storage sites and contractor yards would be used on atemporary basis and would be reclaimed, as appropriate, upon completion of construction.2.1.5.3 Fuel Transfer StationsFuel storage sites would be established at approved contractor yards and pipe storage sites. Noother fuel stations would be constructed. Gasoline and diesel fuel would be transported daily byfuel trucks from the fuel transfer station to the construction area for equipment fueling. The totalfuel storage capacity would vary from yard to yard, depending on daily fuel requirements.Typically, a 2- to 3-day supply of fuel would be maintained in storage, resulting in a maximumvolume of approximately 30,000 gallons of fuel at each storage location. Each fuel storagesystem would consist of the following:• Temporary, aboveground, 10,000- to 20,000-gallon, skid-mounted tanks and/or 9,500-gallonfuel trailers;• Rigid steel piping;• Valves and fittings;• Dispensing pumps; and• Secondary containment structures.The fuel storage system would have a secondary containment structure capable of holding 110percent of the volume of the fuel storage tanks or fuel trailers. The proposed Project SPCC Planand the CMRP (see Appendix G) specify that secondary containment would be utilized for fuelstorage facilities that are not monitored or attended on a full-time basis. Similar to automotiveservice stations, there would not be secondary containment facilities for fuel trucks that would betransferring fuel to/from the bulk storage tanks, as these would be attended during all fueltransfer operations. As stated in the SPCC, adequate spill cleanup materials and equipmentwould be available onsite.Before receiving or off-loading fuel, all trucks and equipment would be grounded to eliminatestatic electricity potential. The distributor would connect a petroleum-rated hose from theProject Description 2.1-26 March 2013
