This table shows a list of BMPs and associated volume removal mechanisms. Primary (removal) means the BMP was designed for this specific mechanism. Secondary (removal) means the BMP provides some volume control 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.
