Chalk Point Generating Station

History & Asbestos Use

Chalk Point Generating Station began operations in 1964 with the first of its coal-fired units, later adding natural gas turbines. During its construction and early decades, asbestos-containing materials were extensively used for insulation and fireproofing throughout the facility. The plant served the greater Washington, D.C. metropolitan area for over five decades before its coal units were retired. Hundreds of workers were employed at the site during its peak operational years.

Exposure Details

Workers at Chalk Point were exposed to asbestos in boiler insulation, pipe lagging, turbine wrapping, gaskets, and refractory materials. Maintenance crews regularly handled asbestos-containing materials during boiler overhauls and routine repairs. The plant's location in the humid Chesapeake Bay region meant that insulation deteriorated faster, requiring more frequent replacement and creating additional opportunities for asbestos fiber release.

Workers at Risk

The following job categories at Chalk Point Generating Station had the highest risk of asbestos exposure:

• Boiler operators
• Maintenance workers
• Pipe fitters
• Insulators
• Electricians
• Millwrights

Health Effects

Former Chalk Point workers have been diagnosed with mesothelioma, asbestosis, and lung cancer attributed to workplace asbestos exposure. Workers employed during the 1960s and 1970s face the highest risk due to the heavy use of asbestos during that era and the limited protective equipment available. Family members may also be at risk from secondary exposure through contaminated work clothing.

Health information is based on established medical research on asbestos exposure. Asbestos is classified as a known human carcinogen by the National Cancer Institute, the Agency for Toxic Substances and Disease Registry, and the U.S. Environmental Protection Agency. Consult a physician for medical advice specific to your situation.
