Representative Deb Haaland of New Mexico, Mr. Biden’s nominee to lead the department, faces a showdown vote in the Senate likely later this month, amid vocal Republican concern for her past positions against oil and gas drilling. But even without her, an agency that spent much of the past four years opening vast swaths of land to commercial exploitation has pulled an abrupt about-face.
