On August 22, 2024, the Board issued its first-notice opinion and order in this sub-docket A of R20-19 (R20-19(A)), proposing amendments to the Board’s rules on coal combustion residual (CCR) surface impoundments (35 Ill. Adm. Code 845). Specifically, the Board proposed adding obligations and restrictions on using CCR storage piles during the closure of CCR surface impoundments by CCR removal. In addition, the first-notice proposal included requirements for the Illinois Environmental Protection Agency (IEPA) to evaluate and act on public complaints over CCR fugitive dust. The proposal also added specifications for air quality monitoring at or near a facility’s property boundary, as well as provisions describing when the monitoring either may or must be imposed by IEPA on facility owners or operators.
