The administration is auctioning off millions of acres of drilling rights and rolling back regulations, raising environmental concerns in states like Wyoming.Reversing a trend in the final years of the Obama presidency, the Trump administration is auctioning off millions of acres of drilling rights to oil and gas developers, a central component of the White House’s plan to work hand in glove with the industry to promote more domestic energy production.Seeing growth and profit opportunities at a time of rising oil prices and a pro-business administration, big energy companies like Chesapeake Energy, Chevron, and Anschutz Exploration are seizing on the federal lands free-for-all, as they collectively buy up tens of thousands of acres of new leases and apply for thousands of permits to drill.In total, more than 12.8 million acres of federally controlled oil and gas parcels were offered for lease in the fiscal year that ended on Sept. 30, triple the average offered during President Barack Obama’s second term, according to an analysis by The New York Times of Interior Department data compiled by Taxpayers for Common Sense, a nonpartisan group that advocates budget discipline.
