The Supreme Court appeared poised Tuesday to significantly weaken the scope of environmental reviews of major infrastructure projects in a case that could hand President-elect Donald Trump an early win on an issue he often hammered on during his first term.

The Supreme Court appeared likely Tuesday to somewhat narrow the scope of environmental reviews required for major infrastructure projects nationwide as it weighed the construction of a Utah rail line that would carry billions of gallons of oil.

Several justices indicated that a federal agency had complied with a federal law by issuing a 3,600-page report on the impact of a proposed railway in Utah.

The U.S. Supreme Court is set on Tuesday to examine the extent to which federal agencies must review the environmental impact of projects they regulate in a dispute over a proposed railway in Utah that was challenged by environmental groups and a Colorado county.

The conservative-leaning Supreme Court has steadily ruled against environmental regulation and may be about to do so again.

The Supreme Court appears poised to narrow the scope of law requiring research on “environmental impacts” before starting large development projects, a more than 50-year-old requirement under the National Environmental Policy Act (NEPA) that critics say has led to delays and increased costs for large-scale energy projects.

The U.S. Supreme Court appears poised to narrow the scope of environmental impact reviews, potentially affecting approvals for major projects like oil drilling and mining.Rachel Frazin reports for The Hill.
