Filed as: Amendments to 74:36 Air Pollution Control Program
South Dakota's Air Quality Program is updating its air pollution control rules to reflect the most current federal standards and definitions. The changes primarily update references from July 1, 2018 to July 1, 2024 in the federal regulations (40 C.F.R.) that South Dakota incorporates by reference, ensuring the state rules align with current EPA requirements. Additionally, the rules refine several definitions—such as clarifying that "criteria pollutants" now explicitly include nitrogen oxides and volatile organic compounds, and changing "nitrogen oxides" to "nitrogen dioxide" in one definition—and make minor technical corrections like fixing a typo in the permit issuance language. These updates affect all businesses and facilities that operate under South Dakota air quality permits, as they must now comply with the more current federal emission standards and monitoring requirements.
