Although it was too late for him to benefit, Daniel Kinel felt relieved in December when the Environmental Protection Agency finally banned TCE. The compound, which has been used for dry cleaning, manufacturing and degreasing machines, can cause cancer, organ damage and a potentially fatal heart defect in babies, according to independent studies and the EPA. It has also been shown to greatly increase people’s chances of developing Parkinson’s disease.

Kinel and three of his colleagues were diagnosed with Parkinson’s disease. They all worked in a law office in Rochester, New York, that sat next to a dry cleaner that had dumped TCE into the soil. Kinel was diagnosed with the neurodegenerative condition at age 43, after working there for seven years. His three colleagues have since died. At least 15 of the firm’s partners developed cancers related to TCE.

“It felt good that we were finally getting rid of this terrible chemical,” said Kinel, whose symptoms now make it impossible to type, write or work as a lawyer. “My children and grandchildren would be protected.”

But his feeling of solace has been short-lived.

The ban has been challenged on multiple fronts since President Donald Trump assumed office for a second time in January. Republicans in the Senate and House introduced resolutions to repeal the ban, which was vulnerable to being overturned through the Congressional Review Act because it was issued shortly before the inauguration. Meanwhile, companies and trade groups have sued to stop the ban in court. A Trump executive order delayed the implementation of the ban until March 21. And last week, the EPA asked a federal appeals court to further delay the ban until the end of May.

TCE, short for trichloroethylene, is one of five toxic substances for which full or partial bans put in place by the EPA under President Joe Biden are now under threat. The Trump administration told the courts that it wants to review all five bans to determine whether they should be rolled back. Those banned substances include a deadly paint stripper called methylene chloride; PCE, a solvent that’s similar to TCE; carbon tetrachloride, which is used as a cleaning fluid; and the cancer-causing mineral asbestos. David Fotouhi, the lawyer Trump nominated to be second-in-command of the agency, tried to overturn the asbestos ban in October, when he was serving as an attorney for a group of car companies. The EPA classifies all of the recently banned chemicals as either........
