About this file

Written by GovTribe AI · Jul 16, 2025

The document is a Water Quality Certification permit issued by the New York State Department of Environmental Conservation (NYSDEC) for a maintenance dredging project by the US Army Corps of Engineers. The permit authorizes hydraulically dredging shoaled areas of the Long Island Intracoastal Waterway in Bellport and Moriches Bays, with approved channel dimensions of 100 feet wide and a maximum depth of -6 feet Mean Lower Low Water (MLLW), plus a 2-foot overdepth allowance. The project will remove approximately 28,775 cubic yards in the first dredge event, with up to 100,000 cubic yards potentially removed in subsequent years, and dredged material will be placed at Smith Point County Park and Cupsogue Beach County Park.

The permit includes strict environmental conditions, including prohibitions on dredging during fish spawning seasons (January 1 to September 30), restrictions on disturbing tidal wetlands, and requirements for sediment core sampling and analysis. The dredging must comply with water quality standards, minimize turbidity, and protect coastal fish and wildlife habitats. The permit is valid from April 27, 2022, to April 26, 2032, with multiple modifications, and was issued to the US Department of the Army for the Federal Navigation Channel maintenance project in Suffolk County, New York.
