American Rock Salt Company LLC

American Rock Salt Company LLC operates the largest-producing salt mine in the United States, located roughly 1,150 feet beneath the Genesee Valley near Mount Morris, New York. Founded in 1997 and brought into production in 2001, it was the first successful new salt mine built in the U.S. in over four decades. The company mines, processes and distributes high-quality rock salt - primarily for road de-icing - across the Northeast Snow Belt, producing up to 18,000-20,000 tons a day at peak and keeping winter highways passable for state and municipal agencies throughout the region.
