On March 7, 2024, for public comment, the Board proposed amendments to Illinois’ wastewater pretreatment regulations. The proposed amendments are “identical in substance” to rule amendments adopted by the United States Environmental Protection Agency (USEPA) during the second half of 2023. Specifically, on August 9, 2023, USEPA updated the reporting and recordkeeping requirements for dental offices as a point source category (40 C.F.R. § 441.50).
