On June 28, the House Energy and Commerce Committee will mark up H.R. 806, the Ozone Standards Implementation Act of 2017. This bill would create a more flexible glide path for manufacturers to comply with the 2015 ozone standard, harmonizing the compliance process for the 2015 standard with the behind-schedule process for the 2008 standard. In doing so, it would allow real ozone reductions to continue through 2025 without the unnecessary economic pain of ozone nonattainment. H.R. 806 would change the five-year review cycle for new standards to a more reasonable 10-year cycle, which is the typical time the Environmental Protection Agency (EPA) needs to complete these reviews. The bill also takes positive steps to address manufacturers’ permitting challenges as they pertain to ozone standards and requires real examination of the impact of international air pollution on domestic ozone levels.
The Clean Air Act has successfully improved air quality across the United States over the past four decades, leading to major reductions of virtually every single air pollutant. Ozone levels have declined roughly one-third since 1980, and the precursors that contribute to ozone—nitrogen oxides and volatile organic compounds—have been cut in half. In fact, the Obama EPA projected that the United States would achieve nearly the same air quality by 2025 even if the 2015 ozone standard was never implemented.
However, incremental improvements in ozone are now coming at an exponential cost. Even though most states can meet the 2015 standard by 2025, they would be unnecessarily thrown into “nonattainment,” a sort of economic penalty box, if the 2015 standard’s deadlines were to stay in place. H.R. 806 solves this problem by phasing the 2015 ozone standard implementation to align with air quality improvements that the Obama EPA found will occur anyway by 2025.
The NAM supports H.R. 806 and looks forward to working with the committee to get this important legislation to the president’s desk.
