EPA | AP Former President Donald Trump will forever leave his mark on the federal government, but some of his administration’s rules aren’t standing the test of time. President Biden wants to reconsider and possibly scrap more than 100 anti-environmental actions his predecessor took during his term, including Trump’s efforts to weaken protections for migratory birds and gray wolves and loosen regulations on pesticides, oil and gas drilling, and appliances. That could take years, but the process has already begun. And Biden is getting an assist from courts. On January 19, the U.S. Court of Appeals for the District of Columbia Circuit rejected Trump’s rollback of emissions regulations for coal-fired power plants, ruling that Trump’s rule replacing the Obama administration’s Clean Power Plan “hinged on a fundamental misconstruction” of the Clean Air Act. Last Friday, a three-judge panel on the D.C. Circuit Court found that parts of Trump’s rollback of ozone pollution laws were illegal. The judges found that elements of Trump’s policy “contravene the statute’s unambiguous language,” and “rests on an unreasonable interpretation of the statute.”
