On August 22, 2024, the Board issued an order proposing amendments to 35 Ill. Adm. Code 845 for first notice. The Board had opened this sub-docket when it adopted new Part 845, Illinois’ first Statewide standards for the disposal of coal combustion residuals (CCR) in surface impoundments. The sub-docket was established to further explore four issues: (1) historic, unconsolidated coal ash fill in the State; (2) the use of temporary storage piles of coal ash, including time and volume limits; (3) fugitive dust monitoring plans for areas surrounding CCR surface impoundments; and (4) the use of environmental justice screening tools.
