The proposed Project would bedesigned to allow full pigging of the entire pipeline with minimal interruption of service. Piglaunchers and receivers would be constructed and operated completely within the boundaries ofthe pump stations (see Figure 2.1.4-1).2.1.4.3 Densitometer FacilitiesDensitometer facilities on the pipeline would be equipped with densitometer/viscometeranalyzers that measure the density of the product prior to delivery. Keystone proposes to installand operate two densitometers within the permanent ROW of the proposed Project. The locationof the densitometers would be on the upstream side of Pump Stations 13 and 14. Densitometerinformation would be incorporated into quality and custody metering located at all injectionpoints and delivery points.Project Description 2.1-20 March 2013
