The facility is situated in the Mississippi River watershed, a region with significant agricultural and industrial activity. Stormwater runoff from mining operations can carry sediment, metals, and other pollutants that may affect local streams and rivers. The area's climate, with seasonal heavy rainfall, increases the risk of runoff events. Regulatory oversight under the EPA's NPDES program aims to control these discharges through permit limits and monitoring requirements.
