The Environmental Protection Agency under former Administrator Scott Pruitt led the administration’s successful war on regulations, slashing enough to produce $350 million in savings and eliminate 300,000 hours of paperwork.

A new report on the agency’s efforts found that the EPA “was a net deregulatory agency,” and a highlight of President Trump’s effort to eliminate many Obama-era regulations.

What’s more, the American Action Forum report found that Pruitt set in place an anti-regulatory mindset that should keep the EPA at the leading edge of deregulation under Trump.

The report is the first to look at the impact of Pruitt, who resigned July 5 after battling a string of controversies involving his leadership.

“While he received a lot of attention for his personal actions, Scott Pruitt’s tenure at EPA moved the agency in a very different direction substantively than under the previous administration,” said the report compiled by Dan Goldbeck, a senior research analyst for regulatory policy at the American Action Forum.

During his time at EPA, Pruitt was backed by Trump because of his deregulation efforts.

In the report, provided to Secrets, Goldbeck cited these highlights:

Final rules from the agency produced nearly $350 million in cost savings and cut more than 300,000 hours of paperwork burdens.

In addition to specific rulemaking actions, Pruitt established the framework for a substantial shift in EPA’s mission and practices. The most notable changes included: narrowing the agency’s regulatory scope, reforming the practice of “sue and settle,” and re-examining the data and analytical processes used to justify rulemakings.

While EPA’s leadership will change, the Pruitt-era policy changes will almost certainly continue. The agency is on track to exceed its deregulatory target for this year, and it is only a matter of time before its most high-profile deregulatory measures (e.g. Clean Power Plan Repeal and adjusted fuel efficiency standards) wind their way through the rulemaking process.

“The fact that EPA was a net cost-cutter during his tenure is significant,” said the report.

Goldbeck lists specific changes that led to the savings, but also emphasized the impact of Pruitt’s war on how the agency’s pro-regulation culture has changed.

“Pruitt’s tenure at EPA marked a dramatic shift in the agency’s underlying mission and culture – perhaps more so than under any other member of President Trump’s cabinet,” he said.
