Ozone limits implementation reform bill reintroduced in US Senate

Sen. Jeff Flake (R-Ariz.) has reintroduced legislation aimed at giving states and communities more time to implement 2015 ground-level ozone limits under National Ambient Air Quality Standards. The measure, S. 452, also would revise the US Environmental Protection Agency’s existing timeline for reviewing NAAQS and air-quality criteria from 5-year intervals to 10-year intervals.
