Tradução automática local · Idioma original da fonte
Resumo
The EPA proposes to approve a petition from the State of Texas requesting that the Houston and Beaumont ozone nonattainment areas be temporarily exempted from NO X control requirements of section 182(f) of the Clean Air Act (CAA) as amended in 1990. The State of Texas bases its request upon preliminary photochemical grid modeling which shows that reductions in NO X would be detrimental to attaining the National Ambient Air Quality Standards (NAAQS) for ozone in these areas. This temporary exemption is being requested under section 182(f) of the CAA.
