Since the 1970s, the federal government has recognized the dangers asbestos poses to the health and safety of those who come in contact with it. To that end, the government empowered the Environmental Protection Agency (EPA) to investigate asbestos contaminated sites across the country and force responsible parties to take accountability in the clean up effort.
On December 11, 1980, Congress enacted the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), informally known as Superfund. The law works by putting a tax on chemical and gas companies as well as giving the EPA the authority to respond to environmental disasters.
To keep track of contaminated sites, the EPA created a National Priorities List (NPL) which includes areas like mines, factories, shipyards, and other industrial sites where asbestos has been detected. Over the years, the EPA has initiated numerous asbestos clean up efforts, putting the financial burden on the shoulders of the asbestos producers and product users.
