Over the weekend, the Trump administration appeared to begin the process of rolling back enforcement of the National Environmental Policy Act (NEPA), the “Magna Carta” of federal environmental law. In a filing submitted Feb. 16, administration officials announced an interim rule titled “Removal of National Environmental Policy Act Implementing Regulations.”

NEPA requires all federal agencies to consider the environmental impact of their work, including by submitting new contracts and permits to rigorous environmental assessments and public comment. Signed into law by President Richard Nixon in 1970 amid growing pollution concerns, NEPA was the nation’s first major environmental law, predating the creation of the Environmental Protection Agency.
