The Trans-Alaska Pipeline System (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. In 1977, construction of TAPS was completed, and major oil production began on the North Slope.
