    Waste Management of PA, Inc. proposes to undertake 10-year maintenance dredging in the Delaware River at the Fairless Hills Basin and berthing areas, which are located at 1121 Bordentown Road in Morrisville, Bucks County, PA (40.138968, -74.755288). Dredging would be to maintain a depth of -41’ MLW. Over the course of the 10-year authorization it is projected that the sediment quantity would total a maximum of 220,000 cubic yards from an 18-acre dredge footprint, and that a total of 5 dredging events would occur. Dredging will be completed using either the hydraulic or mechanical method, depending on equipment availability for each individual dredging cycle. All resultant dredged material would be disposed of at either Money Island CDF, located in Falls Township, PA (40.125943° N Longitude: -74.792385° W), or at Biles Island CDF, located in Falls Township, PA (40.175943° N, -74.749050° W). The first dredging cycle is expected to begin in the fall or winter of 2025 into 2026. The stated purpose of this project is to maintain sufficient water depths for safe navigation and docking at the Fairless Hills Basin and berthing areas.
