A settling CWA defendant that violated its wastewater discharge permit and failed to respond to an EPA information request in connection with its wastewater treatment plant in Gary, Indiana, must develop and implement a control plan addressing discharges from its combined sewer overflow outfalls into the local water bodies, implement additional operational changes focused on improving the wastewater treatment system's efficiency, pay a $75,000 civil penalty, perform a supplemental environmental project costing $175,000, and provide schedules for the remaining remediation under a CWA and TSCA consent decree entered into by the parties in 2003.
