SPOKANE TERMINAL

The Spokane Terminal receives gasoline, diesel, and jet fuel (Jet A) by pipeline from the Marathon and Yellowstone pipelines, rail tank car, and tank trucks, storing it in tanks, then loading the fuels into tank trucks for further distribution.

On-site equipment consists of one (1) loading rack with three (3) loading bays, plus associated tanks, pumps, and piping. The loading rack is equipped with a vapor combustion unit (VCU) to control emissions from the loading operation. The pipeline's capacity for deliveries to the Spokane Terminal is 1,600 bbls/hr of total product. Deliveries across the rack will not exceed 8,000,000 bbls annually. Butane storage and blending assets are also located at the facility, including a butane storage tank with a capacity of 60,000 gallons.
