Missouri & Illinois Industrial, Chemical & Refinery Sites

St. Louis's chemical and industrial corridor was one of the most concentrated in the nation. Monsanto, Mallinckrodt, Wagner Electric, Anheuser-Busch, and the Illinois side's steel mills and refineries at Alton, Granite City, and Roxana all used asbestos-containing materials extensively from the 1930s through the 1980s. Missouri workers crossed the river regularly — their exposure histories cross state lines, and so do their claims. Click any site to read its full exposure history.

Illinois Industrial & Refinery Sites

Illinois law applies to these facilities. Asbestos claims arising from exposure at Illinois worksites are governed by Illinois law — including a 2-year statute of limitations under 735 ILCS 5/13-202, shorter than Missouri's 5-year window. Missouri residents who worked at Illinois industrial sites frequently have claims under both states' laws simultaneously depending on which compensation avenue is pursued.
