What the agency says

The Environmental Protection Agency (EPA) is proposing to determine that the Anne Arundel County and Baltimore County, Maryland sulfur dioxide (SO<INF>2</INF>) nonattainment area attained the 2010 1- hour primary SO<INF>2</INF> national ambient air quality standard (2010 SO<INF>2</INF> NAAQS) by the applicable attainment date of September 12, 2021. This determination is based on certified ambient air quality data from the 2018-2020 monitoring period, relevant modeling analysis, and additional emissions inventory information. This action, if finalized, will address the EPA's obligation under Clean Air Act (CAA) section 179(c) to determine whether the Anne Arundel and Baltimore County SO<INF>2</INF> nonattainment area (referred to hereafter as the Anne Arundel-Baltimore County Area, or simply the Area) attained the 2010 SO<INF>2</INF> NAAQS by the September 12, 2021 attainment date.
