Since promulgation of new source performance standards (NSPS) for fluoride control in the phosphate fertilizer industry, in 1975, commercial applications of a few new systems that reduce air pollution from phosphate plants have been reported. These include scrubbing system modifications that reduce the size of ponds used to cool process water, and reduce pond fluoride emissions. Also, a proprietary new process produces a stable granular triple superphosphate (GTSP) directly. This process reduces or eliminates the emissions of fluorides and fugitive particulate during the curing, storage period. The new GTSP process also eliminates the scrubbing of certain process gas, thus reducing required cooling pond area and pond fluoride emissions. There is currently insufficient process experience and source test data for firm conclusions about fluoride control potential. The recommendation is therefore made not to develop NSPS revisions now, but to assess additional developments in this industry in four years, and then reconsider possible revision.
