The Blue Water region — the St. Clair River from Port Huron down to Algonac — is a power corridor. The DTE St. Clair, Belle River, and Marysville generating stations line the river, and the Port Huron shipyards built and repaired Great Lakes vessels. Coal-fired power and shipbuilding are among the most asbestos-intensive work there is, and the region’s trades were reportedly exposed for full careers.

Michigan allows three years from a mesothelioma or asbestos-cancer diagnosis — measured from when the disease was or should have been discovered — to file a personal-injury claim (MCL 600.5805). A wrongful-death claim must generally be brought within three years of death (MCL 600.5852), but it cannot revive a claim that had already lapsed during the person’s lifetime, so the timeline is worth confirming early. Cases are filed in the county Circuit Court of proper venue; Michigan has no statewide asbestos MDL, and Wayne County (Detroit) has historically carried the state’s largest asbestos docket.
