Wastewater discharges from Respondent's facilities include municipal waste, biological oxygen demand,total suspended solids,enterococcus, and therefore contain "pollutants," as defined by CWA Section 502(6), 33 U.S.C. § 1362(6). 14. As detailed herein, Respondent's discharge of pollutants in wastewater into navigable waters constitutes a "discharge of pollutants"within the meaning of CWA Section 502(12), 33 U.S.C. § 1362(12). 1 These two WWTPs are the subject of a separate Order,SDWA-UIC-AOC-2017-0002.
