PART 1: THE FACILITY AND THE DANGER
Facility Overview and History
The Detroit Edison Trenton Channel Power Plant was one of the largest coal-fired generating stations in southeastern Michigan for much of the twentieth century. Located along the Detroit River in Trenton, Michigan — Wayne County, approximately 20 miles south of downtown Detroit — the plant served as a core unit in Detroit Edison’s (now DTE Energy’s) power generation network, supplying electricity to residential, commercial, and industrial customers across greater Detroit and the automotive manufacturing corridor.
Trenton Channel ranks among several major Wayne County industrial sites where workers may have been exposed to asbestos-containing materials during the peak industrial decades. Comparable southeastern Michigan facilities where similar exposures have been alleged in litigation include the Ford River Rouge Complex in Dearborn, the Chrysler Jefferson Assembly plant in Detroit, and the GM Hamtramck Assembly facility — all locations where asbestos-containing materials were standard during the same era.
Construction and Operational Timeline
- 1920s: Reportedly constructed and began operations
- Mid-20th century: Significant expansions and upgrades reportedly occurred
- 1950s–1970s: Peak operation — the era when asbestos-containing materials were the industry standard across American industrial facilities
- Late 20th century: Decommissioning and demolition activities
The plant’s Detroit River location provided cooling water for steam-cycle systems and barge delivery access for coal.
Ownership and Corporate Succession
- Original operator: Detroit Edison Company
- Current corporate successor: DTE Energy
Detroit Edison reportedly operated multiple power generating facilities across southeastern Michigan. Industry practice and patterns established through comparable facility litigation confirm that asbestos-containing materials were standard in utility power plant construction and maintenance throughout the twentieth century.
Unionized Workforce and Trades
The Trenton Channel plant’s workforce was represented by multiple trade unions whose members may have been exposed to asbestos-containing materials during their employment. Michigan union locals whose members reportedly worked at Detroit Edison facilities — and whose members have pursued asbestos-related claims in Wayne County Circuit Court — include:
- Asbestos Workers Local 25 (Detroit) — journeymen insulators who applied and removed asbestos-containing pipe covering, block insulation, and boiler insulation at utility and industrial facilities throughout southeastern Michigan
- Pipefitters Local 636 (Detroit) — pipefitters and steamfitters who worked on steam and hot water systems at power plants, routinely in close proximity to asbestos-containing pipe insulation
- UAW Local 600 (Dearborn) — while primarily associated with Ford operations, members performed maintenance and construction work at industrial facilities across Wayne County
- UAW Local 235 — represented workers at Detroit-area manufacturing and industrial facilities; members may have performed work at or near Detroit Edison properties
Workers diagnosed with mesothelioma or asbestosis have three years from their diagnosis date to file a claim under Michigan law. If you worked at Trenton Channel or comparable Detroit industrial facilities and have been diagnosed, call an asbestos cancer lawyer in Detroit today.
Demolition and Decommissioning Hazards
After decades of operation, the Trenton Channel Power Plant was decommissioned. Demolition work carries serious asbestos exposure risk — aging insulation, fireproofing, and structural materials disturbed during teardown release asbestos fibers into the air workers breathe. Michigan’s Environmental, Great Lakes, and Energy (EGLE) agency enforces NESHAP (National Emission Standards for Hazardous Air Pollutants) compliance for asbestos during renovation and demolition. Records generated under NESHAP for this site may document asbestos-containing materials identified and abated. Workers engaged in demolition — including laborers, ironworkers, and insulators — may have been exposed to asbestos-containing materials disturbed during decommissioning.
Why Asbestos-Containing Materials Were Standard at Power Plants
The Thermal and Engineering Demands of Coal-Fired Generation
Coal-fired power plants like Trenton Channel operate on the Rankine steam cycle:
- Coal combustion heats water into high-pressure steam
- Steam drives turbines connected to electrical generators
- Steam runs at temperatures often exceeding 1,000°F and pressures measured in hundreds of pounds per square inch
Every steam pipe, boiler surface, turbine casing, and associated component required insulation rated for sustained extreme heat. Asbestos-containing materials dominated this market from the 1920s through the mid-1970s. The same operating conditions — and the same materials — existed at comparable Michigan utility facilities throughout the industrial corridor.
Why Asbestos-Containing Materials Dominated the Market
From the 1920s through the mid-1970s, asbestos-containing materials were the industry standard for industrial insulation. Asbestos offered properties no competing material could match at the price:
- Extreme heat resistance — withstands temperatures that destroy organic materials
- High tensile strength — can be woven, cast into cement, or blended into durable composite products
- Cost efficiency — large North American mining operations kept prices competitive with inferior alternatives
- Versatility — incorporated into pipe covering, block insulation, gaskets, boiler cement, floor tile, roofing, and fireproofing compounds
These same materials were ubiquitous across southeastern Michigan’s entire industrial base — from power plants to automobile assembly plants. Workers moving between multiple facilities may have accumulated significant cumulative asbestos exposure over careers spanning decades.
Major Manufacturers Who Supplied Asbestos-Containing Products to Utilities
Manufacturers who reportedly supplied asbestos-containing materials to power plants across the United States — including Michigan utility facilities — include:
- Johns-Manville — the dominant North American asbestos manufacturer; reportedly supplied insulation and fireproofing to Detroit Edison facilities
- Owens-Illinois — manufactured asbestos-containing pipe covering and thermal insulation; Michigan-based during part of the relevant period
- Owens Corning — supplied thermal insulation and building materials containing asbestos
- Combustion Engineering — major supplier of asbestos-containing boiler components
- Armstrong World Industries — manufactured asbestos-containing floor tiles, ceiling materials, and insulation
- Celotex — produced asbestos-containing insulation board and thermal products
- Crane Co. — supplied asbestos-containing valves, fittings, and packing
- W.R. Grace & Company — produced asbestos-containing fireproofing products, including Monokote
- Eagle-Picher Technologies — manufactured asbestos-containing thermal insulation and gasket materials
- Garlock Sealing Technologies — produced asbestos-containing gaskets and packing widely used in Michigan industrial settings
Industry Knowledge and Alleged Concealment
Internal documents recovered through decades of asbestos litigation — including cases filed in Wayne County Circuit Court — show that major manufacturers knew as early as the 1930s and 1940s that inhaling asbestos fibers causes serious disease. These manufacturers allegedly continued selling products without adequate warnings for decades. Workers at facilities like Trenton Channel may have handled asbestos-containing materials for entire careers without protective equipment or any meaningful hazard information.
The manufacturers’ alleged concealment does not reset your legal deadline. Michigan mesothelioma victims have three years from diagnosis to file. Call a Michigan asbestos cancer attorney today.
PART 2: ASBESTOS-CONTAINING MATERIALS AT TRENTON CHANNEL
Asbestos-Containing Materials Allegedly Present at the Facility
Based on regulatory records, industry practice, and patterns established through litigation involving comparable Detroit Edison facilities and Michigan utility plants — including cases filed in Wayne County Circuit Court — the Trenton Channel Power Plant may have contained asbestos-containing materials in numerous locations throughout the facility.
Boiler Systems
The coal-fired boilers were among the heaviest users of asbestos-containing materials at any power plant. Boiler systems at facilities of this type may have incorporated:
- Boiler block insulation — asbestos-containing materials reportedly supplied by Johns-Manville and Owens-Illinois, applied to boiler exteriors to reduce heat loss
- Asbestos-containing insulating cement — reportedly used to fill joints, gaps, and irregular surfaces around boiler components
- Asbestos rope and woven gasket materials — reportedly used to seal boiler doors, access panels, and penetrations; products supplied by Garlock and similar manufacturers
- Refractory materials — reportedly containing asbestos, used to line combustion chambers exposed to direct flame
- Asbestos cloth and blanket materials — reportedly used for high-temperature applications around boiler surfaces; commonly supplied by Johns-Manville and Owens-Illinois
Insulators from Asbestos Workers Local 25 and pipefitters from Pipefitters Local 636 may have worked directly with or in close proximity to these materials during installation, maintenance, and repair.
Steam and Hot Water Piping Systems
Miles of steam and hot water piping reportedly ran throughout the facility. That piping may have been insulated with asbestos-containing materials, including:
- Asbestos pipe covering — the industry standard for insulating high-temperature steam pipes; typically supplied as preformed insulation shells composed of asbestos fiber, silicate compounds, and binding agents
- Calcium silicate pipe insulation — a Johns-Manville product line that incorporated asbestos fibers; widely used in utility power plants throughout this period
- Asbestos-containing fitting and elbow insulation — preformed insulation applied to pipe fittings, elbows, tees, and valves where standard pipe covering cannot conform
- High-temperature rope insulation — asbestos rope reportedly used to seal around pipe penetrations, valve stems, and irregular surfaces
Pipefitters from Local 636, steamfitters, and boilermakers performing installation, maintenance, repair, or replacement of this piping may have regularly handled, cut, wrapped, or removed asbestos-containing pipe insulation. Asbestos fibers become airborne and respirable when pipe insulation is cut, scraped, sanded, or removed — and that work happened repeatedly at every maintenance cycle over multiple decades.
Turbine and Generator Systems
Steam turbines at the plant may have utilized asbestos-containing materials in multiple components:
- Turbine casing insulation — reportedly containing asbestos, applied to reduce heat loss and maintain operating efficiency
- Asbestos-containing valve packing and gaskets — reportedly used in turbine inlet and outlet valves; products supplied by Crane Co. and Garlock
- Turbine bearing insulation — reportedly containing asbestos-containing materials
- Generator cooling system components — some reportedly incorporating asbestos-containing materials in seals, gaskets, and insulation
Turbine maintenance required workers to enter confined spaces where asbestos-containing materials had degraded over years of thermal cycling — conditions that concentrate airborne fiber levels.
