Illinois: Water
The Pollution Control Board proposed amendments to regulations governing sewer discharge criteria. The amendments would align Illinois wastewater pretreatment requirements with regulations adopted by EPA during the second half of 2023, update incorporations by reference, and make non-substantive corrections. Comments are due May 13, 2024. See https://www.ilsos.gov/departments/index/register/volume48/register_volume48_13.pdf (pp. 4586-607).
