U.S. Steel, Minnesota Ore Operations is a taconite plant on Minnesota’s Iron Range. It produces high-grade iron ore pellets for use at integrated steel mills. Approximately 70% of the ore processed is sent to the tailings basin for impoundment. The U.S. Steel, Minnesota Ore Operations has a 7,900 acre tailings basin that is divided into smaller cells that range in size from 100 to 400 acres. The closed industrial solid waste landfill and the original solids/sludge land treatment area are located in Cell A-2 of the 7,900 acre tailings basin located north of the taconite processing plant. A new 6 acre land treatment area will be located on top of an overburden stockpile located in the NW 1/4 of the NW 1/4 of Section 6, Township 58N, Range 18W. Waste tires are generated by mining operations and are stored on site until enough are generated to send them off-site for recycling. The waste tire storage area is located on the southeast corner of the Central Shop in the area of the taconite processing plant.

The industrial solid waste disposal area is approximately 10 acres in size and is closed. Construction of the final cover system for the landfill was completed in 2012. No additional acceptance or disposal of industrial solid waste or demolition debris is permitted in this area. The landfill was closed with approximately 490,039 cubic yards of waste and coarse tailings in place. U.S. Steel–Minntac will be responsible for maintaining the final cover system of the landfill.
