ALYESKA TAPS PS 11 / GLENNALLEN RESPONSE BASE - Oil Pipeline Facility in Glennallen, Alaska

ALYESKA TAPS PS 11 / GLENNALLEN RESPONSE BASE is an oil pipeline facility located at Mile 188 of the Glenn Highway in Glennallen, Alaska. It is a key component of the Trans-Alaska Pipeline System (TAPS), which transports crude oil from Prudhoe Bay to Valdez. This facility functions as a pump station and a spill response base, supporting the safe and efficient operation of the pipeline across challenging Alaskan terrain. The facility operates under the regulatory oversight of the U.S. Pipeline and Hazardous Materials Safety Administration (PHMSA) and complies with 49 CFR Part 195 for hazardous liquid pipelines. TAPS is one of the largest pipeline systems in the world, with a diameter of 48 inches and a capacity of over 2 million barrels per day. Pump stations like PS 11 are critical for maintaining flow pressure across the mountainous and permafrost regions of Alaska. Environmental considerations are paramount for TAPS operations, as the pipeline traverses sensitive ecosystems including rivers, forests, and permafrost areas. PS 11's role as a response base ensures rapid containment and cleanup capabilities in the event of a spill, minimizing impact on the surrounding environment. The facility supports the continuous delivery of crude oil to the Valdez Marine Terminal, a vital link in U.S. energy infrastructure.

The facility is located in the Copper River Valley near the Wrangell-St. Elias National Park and Preserve, an area characterized by diverse wildlife and pristine waterways. The pipeline corridor crosses several major rivers and seismic zones, requiring robust monitoring and leak detection systems. Cathodic protection and regular inspections are employed to prevent corrosion and maintain pipeline integrity, reducing the risk of environmental contamination.
