Plant Description and Operating Era

The Johns-Manville Lompoc CA plant allegedly served as a bulk asbestos-fiber processing and asbestos-containing minerals site tied to J-M’s Western U.S. mining and product-supply chain during the twentieth-century U.S. asbestos era. Bulk asbestos fiber processing and industrial minerals work at Lompoc allegedly fed J-M’s West Coast asbestos-cement, asbestos-thermal, and asbestos-textile downstream product plants. Operations wound down in the aftermath of J-M’s August 26, 1982 Chapter 11 filing.
