History & Asbestos Use

Ashland Oil Company (later Ashland Inc.) established its refinery in Catlettsburg, Kentucky in 1924 along the Big Sandy River at the confluence with the Ohio River. The refinery was the company flagship facility and a major employer in the tri-state area of Kentucky, West Virginia, and Ohio. The refinery is now operated by Marathon Petroleum following the 2005 formation of Marathon Petroleum Corporation from Ashland refining assets. Asbestos was used throughout the facility from the 1920s through the late 1970s.

Workers performing routine maintenance and turnaround operations disturbed asbestos-containing materials on a regular basis, particularly in the older sections of the facility. The refinery tri-state workforce drew workers from Kentucky, West Virginia, and Ohio, spreading the impact of asbestos exposure across a wide geographic area.
