Board Grants “Time-Limited Water Quality Standard” to MWRD for Dissolved Oxygen.pdf
On December 16, 2021, the Board issued an order granting a “time-limited water quality standard” (TLWQS) to the Metropolitan Water Reclamation District of Greater Chicago (MWRD). A TLWQS is a form of temporary relief from a Board water quality standard. MWRD sought a dissolved oxygen TLWQS to account for discharges into the Chicago Area Waterways System (CAWS) from combined sewer overflow (CSO) outfalls. These CSO outfalls are associated with MWRD’s O’Brien, Calumet, and Stickney water reclamation plants. The TLWQS has a five-year term.
