EPA Challenged Administration’s Safety Projections From Mileage Freeze

WASHINGTON — The Environmental Protection Agency privately challenged the Trump administration’s rationale for freezing Obama-era mileage standards, saying the proposal actually would increase U.S. highway deaths.

In announcing the mileage proposal earlier this month, officials with EPA and Department of Transportation contended the mileage freeze would save about 1,000 lives a year. But in a June e-mail, senior EPA staffers told the Office of Management and Budget — the White House office charged with evaluating regulatory changes — that it would slightly increase highway deaths, by 17 annually.

The “proposed standards are detrimental to safety, rather than beneficial,” William Charmley, director of the assessments and standards division of EPA’s office of transportation and air quality, said in a June 18 interagency e-mail, released Aug. 14.



While the Trump administration has said it wants to freeze mileage standards after 2020, agencies still are seeking public comment on that and other options, EPA spokesman John Konkus said Aug. 14. “These e-mails are but a fraction of the robust dialogue that occurred during interagency deliberations for the proposed rule,” he said.

The Obama-era rules, which lay out years of increasingly toughened mileage standards, were one of the former administration’s biggest efforts against climate-changing tailpipe emissions and also were meant to lessen Americans’ overall dependence on the gas pump.

The Trump administration’s own public report on the mileage freeze proposal projected that it would cut tens of thousands of auto industry jobs. EPA acting Administrator Andrew Wheeler had emphasized the safety projections as one of the strongest arguments for the mileage freeze.

Essentially, the Trump administration argues in part that the mileage freeze would make vehicles cheaper, because automakers would not have to spend as much on fuel efficiency. As a result, the Department of Transportation argued, safer, newer vehicles would get on the road more quickly.

The June EPA e-mail says the administration’s proposal miscalculates the amount of vehicle turnover as a result of any mileage freeze.

A former EPA senior staffer, Jeff Alson, said that the documents released Aug. 14 showing the interagency discussions on the freeze made clear that “EPA career staff were totally ignored, despite DOT trying to deceive the public into thinking that EPA supports the analysis.”

Department of Transportation spokeswoman Karen Aldana defended the decision-making process. “As is typical for any joint rulemaking, the agencies provided feedback to each other as they developed their policy and analysis for the proposal,” she said.

Sen. Tom Carper (D-Del.), an opponent of the mileage freeze, said Aug. 14 that the documents give the public “even more evidence that it’s based on bogus science and fundamentally flawed assumptions.”

He said the proposed rule “almost certainly will be struck down in court.” California and 16 other states already have filed suit to block any change in the fuel-efficiency rules.
