The Minnesota Pollution Control Agency (MPCA) maintains a statewide network of air quality monitoring, including three air quality monitors around the refinery – the most for any facility in the state. These monitors show that air quality around the refinery is well within clean air standards and is consistent with some of the best air quality measurements found anywhere in the state.  Learn more about the MPCA’s air monitoring network.
