U.S. Sen. Jeff Flake (R-AZ) introduced a resolution last week to permanently block the Environmental Protection Agency’s final 2015 ozone ruling, a move that could potentially save $19 billion to $25 billion annually.

The measure, Senate Joint Resolution 25, was co-signed by 30 U.S. senators, including Flake, and could shave expenses substantially. 

In March, Flake introduced the Ozone Regulatory Delay and Extension of Assessment Length Act to allow the EPA extra time to review air quality standards with the goal of providing more certainty for state agencies and businesses.

“It’s time to bring EPA down to Earth, starting with the elimination of this egregious rule and its $25 billion price tag,” Flake said.

The bill would lengthen the EPA’s present timeline to revise National Ambient Air Quality Standards (NAAQS), specifically criteria for measuring air quality, extending the current five-year cycles to 10-year intervals. Additionally, the measure would also ban the EPA from finalizing or imposing a revised ozone model until 2018.
