NPDES Permits in New England

Chelsea Sandwich, LLC (MA0003280)

Photo of Chelsea Sandwich facility, Chelsea, MassachusettsThe Chelsea Sandwich facility, which is located in Chelsea, Massachusetts, is engaged in the receipt, storage, and distribution of petroleum products. The spectrum of fuels handled by this facility consists of distillate (e.g., diesel, kerosene, and No.2 Fuel Oil) and residual products (e.g., No.6 Fuel Oil) as well as various product additives. Petroleum products are received in bulk quantities at the terminal’s marine vessel dock. Product is then transferred to aboveground storage tanks located within the facility’s two tank farm areas. Final distribution of product is conducted primarily at the facility’s truck loading rack and on occasion at the vessel dock when product is shipped off-site. The NPDES discharge consists of: 1) treated storm water runoff from pervious and impervious areas at the facility including the tank farm and loading rack; 2) ground water undergoing treatment as a result of a previous fuel oil spill; 3) a small volume of boiler blow-down water; and 4) occasionally water used for the hydrostatic testing of repaired tanks. The storm water, boiler blow-down, and hydrostatic test water discharges are to the Chelsea River through Outfall 001. This permit also establishes an internal waste stream (Outfall 002) which will discharge treated ground water into the storm water conveyance system upstream of Outfall 001.
