The port was built in the 1950s by Bethlehem Steel to facilitate the transhipment of iron ore mined in Marmora and conveyed to Picton via rail and, after the Marmoraton mine shut down in 1978, activity at the port diminished drastically with annual loads of sodium chloride delivered by ship occurring most falls from the 1980s until 2019.
Marine terminals include inside and outside storage, and some 6,000 square feet (560 m2) of berthing space for ships carrying general cargo.
[3] The tonnage of cargo passing through the port is made up mostly of aggregate materials, chiefly road salt, but also farming products, new and recycled scrap steel.
The plea resulted from a 2016 discharge of petroleum coke (petcoke) which Terminals was stockpiling on White Chapel Road.
Petcoke dust, considered by the U.S. Environmental Protection Agency to be dangerous to heart and lung health, was found to have drifted onto several nearby residences, including a neighbouring pool.
