On February 7, 2017, the Region issued a Clean Water Act Administrative Order (Order) to the City of Waterbury, Connecticut to address ongoing sanitary sewer overflows (SSOs). On at least four occasions since January 1, 2012, the City reported discharging untreated sewage from various components of its collection system to the Mad River, Trumpet Brook, and an undefined small stream. EPA issued the Order under Sections 308(a) and 309(a) of the Clean Water Act requiring that, in order to prevent future SSOs, the City will update its Capacity, Management, Operations, and Maintenance program and submit documentation of its updates to EPA and the Connecticut Department of Energy and Environmental Protection (CT DEEP). The Region worked in close coordination with the CT DEEP in this matter.
