Under Republican Gov. Larry Hogan, Maryland has petitioned the Environmental Protection Agency for help bringing ozone pollution in the state to a safe level. Granting this request should be a no-brainer for EPA Administrator Scott Pruitt.

“My guess is that the bulk of the litigation is ahead of us,” said Richard Revesz, an environmental and regulatory law expert at New York University School of Law. “All this litigation is going to consume the full four years.”

It’s already been almost 17 years since the EPA first concluded that it should issue a rule limiting mercury emissions from coal- and oil-fired power plants. It’s been more than five years since the agency actually did issue such a rule. And it’s been more than two years since the nation’s power plants started complying with the rule. All along the way, the EPA, states, power companies, and public health and environmental groups have been fighting about the rule in court. They show no signs of stopping anytime soon.

It’s no secret that the Trump administration would like to undo as much of Obama’s environmental legacy as possible by rescinding or repealing regulations. Under the law, that process is difficult, but Trump’s agency heads now seem to be looking for an easy way to undo rules without officially rescinding or repealing them.

It’s no secret that the Trump administration would like to undo as much of Obama’s environmental legacy as possible by rescinding or repealing regulations. Under the law, that process is difficult, but Trump’s agency heads now seem to be looking for an easy way to undo rules without officially rescinding or repealing them. Courts have rejected this kind of behavior in the past. Let’s hope they do so this time too.

Richard Revesz, director of the Institute for Policy Integrity at New York University School of Law, said a D.C. Circuit ruling resolving that uncertainty would head off further courtroom wrangling over the issue. “There is no compelling reason for the D.C. Circuit to delay facing those issues for years, with the serious negative consequences that would entail, when it is likely to already have decided them,” he said.

“It’s uncharted territory for a president to attempt to completely lift a moratorium like the one President Obama instituted,” says Jayni Hein, policy director at New York University’s Institute for Policy Integrity. Past presidents have tweaked the size of previously designated protected areas, she says, but a full-on repeal is unprecedented and would likely end up in the courts.

Pruitt is in no position to declare victory and merely preserve the status quo. Large swaths of the country are violating the air and water standards that both Republican and Democratic administrations have agreed were necessary to protect public health.

What President Trump’s environmental executive order fails to acknowledge is that the Obama Administration’s estimate of the social cost of carbon is consistent with the guidance from Circular A-4. Asking each agency to develop its own metric will waste agency resources and open rules up to needless and risky legal challenges.

“Staying in the Paris accord signals to the world that the long-term policy of the United States is to control greenhouse gases,” Richard Revesz, an environmental law expert who wrote a useful book about the climate wars, told me. “The U.S. gets large benefits from the greenhouse gas reductions occurring outside our borders, and the actions of the U.S. are likely to have an impact on the actions of other countries. Withdrawing from it is likely to lead some other countries to relax their own commitments, to the detriment of the United States.”
