On Thursday, the Senate approved Michael Regan to head the Environmental Protection Agency, placing the North Carolina regulator in charge of restoring the Trump administration's relaxed air and water pollution rules.

Regan will head an organization that will play a significant regulatory role in President Joe Biden's ambitious climate policy as the Environmental Protection Agency administrator. Crafting a new carbon law for power plants, now that the Trump EPA's version has been struck down by a federal judge, strengthening tailpipe pollution restrictions for vehicles and light trucks, and reducing methane spills from the oil and gas industry would be at the top of his to-do list.

Biden's efforts to remove greenhouse gases from the nation's energy grid by 2035 and put the country on track to reach net-zero emissions by mid-century would depend heavily on the power plant law to limit carbon dioxide emissions.

Janet McCabe, the Biden administration's candidate for Regan's deputy, has a long history of writing strict environmental legislation, including the Obama administration's version of the power plant code, which was blocked by the Supreme Court before it could go into effect. Dan Utech, the Obama administration's chief of staff, and Joe Goffman, the office in charge of air quality rules, have also returned to the department to work under Regan.

Though Republican lawmakers and state officials may support Regan on topics such as PFAS cleanups and the Superfund program for polluted lands, it is unlikely that he will be able to reconcile Biden's proposals for ambitious climate change with Republicans' resistance to laws that they feel threaten their states' fossil fuel industries.
