Board Proposes First-Notice Rules for Ambient Air Monitoring of Ethylene Oxide.pdf
On January 16, 2020, the Board proposed new air monitoring rules for determining ambient levels of ethylene oxide (EtO) across Illinois (35 Ill. Adm. Code 249). Section 9.16(n) of the Environmental Protection Act (415 ILCS 5/9.16(n), added by P.A. 101-22, eff. June 21, 2019) requires the Illinois Environmental Protection Agency (IEPA) to both “conduct air testing to determine the ambient levels of [EtO] throughout the State” and, within a specified timeframe, “submit rules for ambient air testing of [EtO] to the Board.” IEPA filed this rulemaking proposal on December 17, 2019. Without commenting on the substantive merits of IEPA’s proposal, the Board proposed the rules for first-notice publication in the Illinois Register.

Board Proposes First-Notice Amendments to Adopt State PSD Permitting Program.pdf
On March 5, 2020, the Board proposed new and amended rules for first-notice publication in the Illinois Register. Specifically, the Board proposed a new Part 204 of its air pollution regulations to create a Prevention of Significant Deterioration (PSD) permitting program that would apply in Illinois instead of the federal PSD program. To accommodate PSD permit appeals, the proposal also would amend existing Parts 101 and 105 of the Board’s procedural rules. In addition, to conform to the new Part 204, the proposal would amend existing Parts 203, 211, and 215 of the Board’s air pollution regulations. See 44 Ill. Reg. 4316 (Mar. 20, 2020).
