Trump moves to unwind over two dozen US air, water regulations
Zeldin started the day by announcing he will narrow the definition of waterways that receive protection under the Clean Water Act - a move that could ease limits on runoff pollution from agriculture, mining, and petrochemicals.
The agency later said it would review the Biden-era clean power plant rule that seeks to reduce carbon emissions from power plants to fight global warming and would also roll back greenhouse gas emissions standards for heavy- and light-duty vehicles for model year 2027 and later.
The power and transport industries together make up around half of U.S. greenhouse gas emissions, and were vital targets in former President Joe Biden's efforts to slow climate change.
The agency also said it will take steps to undo a scientific finding from 2009 that greenhouse gas emissions endanger public health, a provision that forms the bedrock of the EPA's greenhouse-gas regulations so far.
The so-called "endangerment finding" came as a result of a Supreme Court ruling in the 2007 Massachusetts v. EPA case that greenhouse gases are covered by the Clean Air Act.
