(2) levels of fecal pollution, human pathogens, or poisonous or deleterious substances are at such levels that shellstock can be made safe for human consumption by either relaying or depuration.

(2) a median fecal coliform colony-forming units (CFU) or geometric mean CFU of 88 per 100 milliliters;

(3) an estimated 90^th percentile of 260 MPN per 100 milliliters for a five-tube decimal dilution test; or
