On April 18, 2019, the Region issued an Administrative Order (Order) to GBC Metals, LLC, d/b/a Somers Thin Strip Brass Group (Somers Thin Strip). On four occasions from February 17, 2015 through June 11, 2017, Somers Thin Strip discharged untreated or partially treated wastewater via an outfall of the City of Waterbury's MS4 to the Naugatuck River without authorization of an NPDES permit. To minimize the re-occurrence of future unauthorized discharges, the Order requires that Somers Thin Strip revise its Spill Prevention, Control, and Countermeasure Plan/Spill Prevention and Control Plan and to prepare a Wastewater Conveyance System Asset Management Plan. The Region worked in close coordination with the CT DEEP in this matter.
