This study investigated the need for new source performance standards (NSPS) for processes that defluorinate phosphate rock to produce an animal feed supplement. This defluorination is accomplished by heating phosphate rock in a kiln or fluidized bed to about 1370C to drive off fluoride as HF. It is recommended that NSPS not be developed. The only three domestic plants, all in Florida, have a very small growth potential. Any expansion within the next five years would probably be a single kiln or fluid bed furnace added to existing facilities at one of these plants. The total combined fluoride emissions are only 27 tons/year for the three plants. The best demonstrated control technology (a fabric filter or a wet scrubber) is already used at each plant, and the Florida State regulations will continue to make this type of control a practical necessity.
