List of BMPs and associated pollutant removal mechanisms. Primary removal (solid circles) means the BMP was designed for this specific mechanism. Secondary removal (half circles) means the BMP provides additional removal of pollutants for this mechanism even though the BMP was not designed for that purpose. An empty cell means the BMP provides limited or no removal for that mechanism.
