There are two proposals published in the Federal Register that affect areas classified as “Serious” for the 2008 8-hour Ozone NAAQS and for areas classified as “Marginal” for the 2015 8-hour Ozone NAAQS.
Some areas were able to attain the standard by the deadline and others will be reclassified because they failed to meet the standard by the deadline.
These two proposals will be in the public comment period until June 13, 2022 and there will be a public hearing on May 9, 2022.
Of note, the Houston-Galveston-Brazoria, TX non-attainment area requested a 1-year attainment extension since they met the two statutory criteria for an extension. However, the EPA is proposing to deny that request as is allowed at the discretion of the Administrator. The EPA is soliciting comment on whether it would be appropriate to grant the state’s request for an extension. |
