Notice of Tentative Decision
Intent to Renew a National Pollutant Discharge Elimination System (NPDES) Permit for the Following Discharges into the Waters of the State of Connecticut
The Commissioner of Energy and Environmental Protection (“Commissioner”) hereby gives notice of a tentative decision to renew a permit to discharge into the waters of the state based on an application submitted by SUMMIT CORPORATION OF AMERICA (“the applicant”) under section 22a-430 of the Connecticut General Statutes (“CGS”). The receiving water associated with this permit renewal is the Naugatuck River.
In accordance with applicable federal and state law, the Commissioner has made a tentative decision that modification of the existing system would protect the waters of the state from pollution.
The proposed permit, if issued by the Commissioner, will require that the subject wastewater be treated to meet the applicable effluent limitations/conditions and will require periodic monitoring to demonstrate that the discharge will not cause pollution.
ACTIVITIES THAT ARE THE SUBJECT OF THE DRAFT PERMIT
Summit Corporation of America (“Summit”) has submitted an application for the renewal of its NPDES permit, CT0001180. The activities which are the subject of this application take place at Summit’s facility at 1430 Waterbury Road in Thomaston, Connecticut. The activity involves the collection, treatment, and discharge of wastewater generated from Summit’s metal finishing operations. The type of wastewater treatment that occurs on-site includes: cyanide destruction, equalization, metals precipitation, flocculation, and clarification. Hexavalent chromium treatment is proposed. The discharge consists of the following types of wastewaters: metal finishing wastewaters; laboratory wastewater; water treatment wastewater; air scrubber wastewater; floor wash water/building maintenance wastewater; tumbling wastewater; on-site groundwater remediation wastewater (proposed); drum rinsing wastewater; reverse osmosis backwash water; boiler blowdown; air compressor blowdown/condensate; and fire suppression test water. The treated wastewater contains the following types of toxic pollutants: metals, cyanide, and total toxic organics. Following treatment, this wastewater is discharged into the Naugatuck River through one outfall, identified as Discharge Serial Number (“DSN”) 001-1, location as follows:
| Discharge ID

|| 73 04' 10.53"
|| Approx. 2 miles south of Reynolds Bridge, east side of the Naugatuck River|
The draft permit allows for up to 400,000 gallons per day of treated wastewater to be discharged from DSN 001-1. This is a continuous discharge. The wastewater discharge is subject to 40 CFR 433 (Metal Finishing Point Source Category).
Effluent Limitations and Conditions: Consistent with section 22a-430-4(l) of the Regulations of Connecticut State Agencies (RCSA), limitations and conditions in this permit are based on: 1) Section 301(b)(1)(C) of the Clean Water Act; 2) 40 CFR 433.16, New Source Performance Standards; 3) Section 22a-430-4(s) of the RCSA; 4) a Case-by-Case determination established in accordance with section 22a-430-4(m) of the RCSA. In addition, the permit contains limitations on internal waste streams. The permit limits and conditions will ensure that the state’s Water Quality Standards, including the antidegradation standards and policies, are met.
