RBF may have its most general application for systems seeking compliance with the LT2ESWTR. On August 11, 2003, the USEPA proposed the LT2ESWTR and included provisions by which RBF could be used as one of the compliance options for providing Cryptosporidium removal credits (USEPA, 2003).While the USEPA has previously recognized (through guidance implementation decisions) that RBF is a technology that can achieve pathogen removal, the LT2ESWTR is the first United States drinking-water regulation that specifically recognizes RBF as a compliance technology option.
