The >300' fully loaded gravel barges are pushed up-river by tugboats to this waterfront depot where the gravel is unloaded and hot mixed to produce road asphalt. The negative riparian impacts are: 1) the prop dredging of the river by the tug pushing oversized barges, resuspending the toxic benthic sediments; 2) streambank erosion from tug wake, and 3) stormwater runoff potentially laden with toxic hydrocarbons, oils, greases and metals. North Fork of the Tred Avon River, Easton, MD
