NOTICE OF WAIVER OF § 401WATER QUALITY CERTIFICATION BY CONNECTICUT DEPARTMENT OF ENERGY AND ENVIRONMENTAL PROTECTION
On August 8, 2024, the Naugatuck Valley Council of Governments (NVCOG) requested that the Department of Energy and Environmental Protection (DEEP) waive its authority to issue a Clean Water Act § 401 Water Quality Certification for certain work on the Naugatuck River. NVCOG provided supplemental information to DEEP on August 30, 2024.
This work is necessary to temporarily mitigate the public safety hazard posed by the approximately 175-year-old unmaintained earthen dam that forms Coe Pond. This earthen dam is part of the Kinneytown Hydro Electric Project, which is located at (i) 677 South Main Street, Seymour CT, TMBL: 11 – 03-35 – 0; (ii) 769 Derby Avenue, Seymour CT, MBL: 12 – 04-34 – 0; and (iii) 0 Hotchkiss Terrace, Ansonia CT, MBL: 036 0001 0003 and regulated by the Federal Energy Regulatory Commission, No. P‑6985.
The work includes enlarging an existing notch in a concrete weir adjacent to the Ansonia powerhouse to 3.5’ deep and 20’wide. Heavy equipment will not be used. The notch will be cut with hand-held tools. The notch will temporarily mitigate the public safety hazard by lowering Coe Pond’s water level and reducing the hydrostatic pressure on the earthen dam.
It is anticipated that the work will take place from September 16 to October 7, 2024.
FERC reviewed and approved this work. DEEP has determined to waive its authority to issue a Clean Water Act § 401 Water Quality Certification.
