BILLINGS, Mont. — The Trump administration is seeking to ease more rules for oil and gas drilling that were adopted under the Obama administration, with the latest changes projected to save energy companies more than $130 million over the next decade. The U.S. Bureau of Land Management proposal would streamline requirements for measuring and reporting oil and gas produced from federal lands. The administration’s critics said it marks yet another instance of Trump backtracking on rules that were meant to ensure companies drill responsibly and that the public gets fairly paid for energy extracted from public lands. Under Trump, federal agencies looking to boost domestic energy production have systematically rolled back industry restrictions — from offshore safety rules in the Gulf of Mexico, to measures to protect imperiled species and prevent greenhouse gas pollution.
