Draft Supplemental Environmental Impact StatementKeystone XL ProjectIn general, about 7,000 cubic yards of gravel would be required for each pipe storage site andabout 4,600 cubic yards of gravel would be required for each contractor yard. The approximately191 temporary access roads would be graveled, as would access pads at ROW crossings ofpublic and private roads. Permanent access roads would also be graveled. About 6inches ofgravel would typically be used at pump stations and mainline valve (MLV) sites. Along portionsof the route, the trench bottom would be filled with padding material such as sand or gravel, toprotect the pipeline coating. Table 2.1-4 lists the approximate amount of borrow material thatwould be required in each state and Table 2.1-5 lists the borrow material required for eachfacility type.Table 2.1-4Borrow Material Requirements by StateStateCubic Yards of MaterialMontana 180,267North DakotaQuantities unknown at this timeSouth Dakota 167,615Nebraska 128,735Kansas a 8,830Total 415,588aBorrow material required for the two proposed pump stations on the Keystone Cushing Extension.Table 2.1-5Total Borrow Material Requirements by Facility TypeFacility TypeCubic Yards of MaterialPipe Storage Site 108,000Contractor Yard 134,400Temporary Access Roads 28,579Access Pads for Road Crossings 37,860Pump Stations 180,000Valve Sites 2,812Permanent Access Roads 242,970Trench Bottom Padding a 85,000Total 415,588aGravel may be replaced with sand or soil.2.1.4 Aboveground FacilitiesThe proposed Project would require approximately 214 acres of land for aboveground facilities,including pump stations, delivery facilities, densitometer sites, and intermediate mainline valves(IMLVs).During operations, Keystone would use approved agricultural herbicides to control thegrowth of vegetative species on all aboveground sites. See Table 2.1-6 for details regardingaboveground facilities.Project Description 2.1-16 March 2013
