Premises Description
Marathon Oil Corporation (founded 1887 as The Ohio Oil Company; renamed Marathon 1962; split 2011 into upstream Marathon Oil and downstream Marathon Petroleum Corporation; both today headquartered in the Houston TX / Findlay OH region) was through the 20th century one of the principal U.S. integrated oil majors. Marathon and its predecessors operated through the asbestos era U.S. refining and petrochemical sites including:
Robinson Refinery (Robinson IL) — historic Mid-Continent refinery
Detroit Refinery (Detroit MI) — Great Lakes refinery
Garyville Refinery (Garyville LA) — major Mississippi River refinery (today the largest U.S. Marathon refinery)
Texas City Refinery (Texas City TX) — Gulf Coast refinery (acquired from BP 2013 — predates Marathon ownership in the documented era)
Catlettsburg Refinery (Catlettsburg KY) — major Ohio River refinery
Canton Refinery (Canton OH) — Ohio refinery
Findlay OH — corporate headquarters and operations
Indianapolis IN / St. Paul MN / Detroit MI / Bismarck ND — terminals and historic operations
Each operated continuously through the asbestos era with extensive asbestos-containing refinery infrastructure.
Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that Marathon Oil / Marathon Petroleum — as premises owner — exposed its refinery operator workforce (OCAW/USW representation) and contractor pipefitters, insulators, boilermakers, and trade workers to extensive asbestos.
Marathon Oil / Marathon Petroleum has been named as a Premises Defendant in publicly filed U.S. asbestos personal-injury and wrongful-death litigation.

Is there a deadline to file an asbestos claim in Indiana?
Indiana law gives 2 years from the date of medical diagnosis to file a personal-injury asbestos lawsuit. Wrongful-death claims must be filed within 2 years from the date of death. The two deadlines run on separate tracks. The personal-injury clock starts at diagnosis, not at exposure — mesothelioma latency is typically 20 to 50 years.
Who else besides Marathon Oil / Marathon Petroleum — Indiana Plant Asbestos Exposure workers may have been exposed?
Yes. Spouses who laundered work clothing carrying asbestos fibers and children of workers who returned home covered in dust are recognized in Indiana asbestos litigation as eligible for secondary (household) exposure claims when they have been diagnosed with an asbestos-related disease. Wrongful-death claims may be filed by surviving family members.
Can workers file both a civil suit and trust-fund claims?
Yes — more than 60 asbestos bankruptcy trusts hold combined funds set aside specifically for victims of asbestos-related disease. Trust-fund claims and civil lawsuits run on separate tracks; both can be pursued in parallel. Each trust has its own filing requirements, exposure criteria, and processing timeline.
