On September 8, 2017 the Illinois Pollution Control Board proposed new regulations in accordance with the effective February 24, 2017 amendment of the Illinois Environmental Protection Act, PA 99-937. This act allows the Board to issue regulations governing Time Limited Water Quality Standards (TLWQS).
TLWQS are a new relief mechanism, which will permit single dischargers, multiple dischargers, watersheds, waterbodies, or waterbody segments to apply and be approved for time limited variances from water quality standards as long as they do not violate federal law. These limitations and requirements are enforced through the regulated entity’s NPDES permit. The proposed regulations establish the general procedures for obtaining a variance and the content required for each application.
Written public comments will be accepted by the Board for at least 45 days after September 8, 2017. Public comments should reference R18-18 and be address to Clerk’s Office, Illinois Pollution Control Board, JRTC, 100 W. Randolph St., Suite 11-500, Chicago, IL 60601 or filed online at www.ipcb.state.il.us.
