What the agency says
The Environmental Protection Agency (EPA) is proposing to determine that the St. Clair, MI sulfur dioxide (SO<INF>2</INF>) nonattainment area attained the 2010 1-hour primary SO<INF>2</INF> national ambient air quality standard (NAAQS) by the date of September 12, 2021. This determination is based on annual SO<INF>2</INF> emissions data, modeled data, and certified ambient air quality data from EPA's December 7, 2021, Clean Data Determination for St. Clair, as well as publicly available additional supporting 2020 data. This action, if finalized, will address EPA's obligation under the Clean Air Act (CAA) to determine whether the St. Clair SO<INF>2</INF> nonattainment area (referred to hereafter as the St. Clair area, or simply the area) attained the 2010 SO<INF>2</INF> NAAQS by the September 12, 2021, attainment date.
