Tulsa-based ONEOK plans to build a new 230-mile, 16-inch refined products pipeline from western Kansas to the Denver International Airport.

The pipeline is part of a $480 million project intended to expand capacity from the Midcontinent and Gulf Coast to the Greater Denver Area, the company said on July 18.

In addition to the pipeline, ONEOK plans to either add or upgrade pump stations for the network. The system’s total capacity will increase by about 35,000 bbl/d. ONEOK plans to finish the project by mid-2026.

"ONEOK is uniquely positioned to help meet the growing demand for refined products and renewable fuels across the greater Denver area of Colorado," ONEOK President and CEO Pierce H. Norton II said in a press release. "This project will provide additional needed capacity for various transportation fuels, including aviation and sustainable aviation fuel to support increasing demand from the expansion of Denver International Airport.

Refined products pipelines transport liquids from refineries to markets and can carry gasoline, diesel, jet fuel, and home heating oil, according to the Environmental Protection Agency.

ONEOK held an open season for the new capacity earlier this year, and the project is fully subscribed under long-term contracts, the company said.

According to ONEOK’s website, the company owns the longest common carrier pipeline system for refined products in the U.S., stretching from the southeast Texas Gulf Coast to cover much of the Midwest, as far as North Dakota.

In June, the company announced it had closed a $280 million acquisition of 450 miles of NGL pipelines from Easton Energy in the Houston area. ONEOK planned to tie in the new infrastructure to its existing NGL, crude and refined products infrastructure.
