Trans-Alaska Pipeline System (TAPS)
Atlantic Richfield Co. and Exxon discovered the Prudhoe Bay oil field in March of 1968. The owner companies (see list below) operating at Prudhoe Bay established Alyeska Pipeline Service Co. (APSC) in 1970 to build and operate TAPS. The State of Alaska and APSC entered into a right-of-way agreement on May 3, 1974; the lease was renewed in November of 2002.
In 1977, construction of TAPS was completed and major oil production began on the North Slope. TAPS is composed of an 800-mile, 48-inch diameter pipeline, the Valdez Marine Terminal (VMT), 11 pump stations (original plans specified 12 pump stations, but only 11 were constructed) and various support facilities. The State right-of-way lease, ADL 63574, applies to the 344 miles of State-owned land in the TAPS right-of-way.
