Despite touting ambitious goals of making America healthier, the Trump administration on Monday revealed in court documents that it is backpedaling on a ban on cancer-causing asbestos.

Last year, under the Biden administration, the Environmental Protection Agency took a long-awaited step to ban the last type of asbestos still used in the US—chrysotile asbestos, aka “white asbestos.” While use of chrysotile asbestos was on the decline, the dangerous mineral has lingered in various gaskets, brake blocks, aftermarket automotive brakes and linings, other vehicle friction products, and some diaphragms used to make sodium hydroxide and chlorine.

With the ban, the US joined over 50 other countries around the world that had already banned its use due to health risks. Generally, asbestos is known to cause lung cancer, mesothelioma, ovarian cancer, and laryngeal cancer. Asbestos exposure is linked to more than 40,000 deaths in the US alone each year, the EPA noted at the time.

“The science is clear—asbestos is a known carcinogen that has severe impacts on public health. President Biden understands that this [is a] concern that has spanned generations and impacted the lives of countless people. That’s why EPA is so proud to finalize this long-needed ban on ongoing uses of asbestos,” Michael Regan, EPA administrator at the time, said in a statement.

“100% safe”

While the move was decades in the making and hailed by health proponents, it still allowed companies a generous period to phase out use of asbestos—in some cases up to 12 years. That didn’t stop industry from taking legal action against the regulation shortly after the EPA’s announcement. The litigation, brought by a number of companies and trade groups, including the American Chemistry Council, has been ongoing since then.
