On May 12, 2022, the Board adopted amendments to keep Illinois’ ambient air quality standards identical in substance to the National Ambient Air Quality Standards (NAAQS). The amendments reflect two actions taken by the United States Environmental Protection Agency (USEPA) during the first half of 2021: (1) USEPA designated one new federal reference method for sulfur dioxide and one new federal equivalent method for coarse particulate matter in ambient air; and (2) USEPA issued the Round 4 area designations under the 2010 primary NAAQS for sulfur dioxide, which had the effect of revoking the 1971 primary NAAQS for sulfur dioxide in all areas of Illinois effective April 30, 2022. Responding to the first USEPA action, the Board updated the incorporation by reference of the List of Designated Reference and Equivalent Methods.

On April 15, 2021, the Board adopted a new Part 845 of its waste disposal regulations (35 Ill. Adm. Code 845), creating Illinois’ first Statewide standards for the disposal of coal combustion residuals (CCR) in surface impoundments. CCR, commonly called “coal ash,” is generated when coal is burned at power plants to produce electricity. By adopting Part 845, the Board fulfilled one of the primary objectives of the Coal Ash Pollution Prevention Act, which the General Assembly passed and Governor JB Pritzker signed into law as Public Act 101-171 (eff. July 30, 2019). The legislation recognized that CCR has caused groundwater contamination and other forms of pollution at active and inactive power plants throughout Illinois and that our environmental laws should be bolstered to ensure surface impoundments are consistently and responsibly regulated.
