NSPS for the Phosphate Fertilizer Industry (40 CFR Part 60, Subparts T, U, V, W, and X) (Renewal)

The New Source Performance Standards (NSPS), for Phosphate Fertilizer Industry (40 CFR Part 60, Subparts T, U, V, W, and X) were proposed on October 22, 1974, promulgated on August 6, 1975, and amended on August 19, 2015 . These regulations apply to both existing facilities and new facilities that engage in the manufacture of phosphate fertilizers (wet-process phosphoric acid plants, super-phosphoric acid plants, diammonium phosphate plants, and triple superphosphate plants), and have a design capacity of more than 15 tons of equivalent phosphorous pentoxide (P2O5) feed per calendar day. These standards also apply to new and existing facilities that store granular triple superphosphate. These same standards establish fluoride emission limitations as a measure of phosphorus-bearing feed material at affected facilities. The affected facilities may include a combination of reactors, filters, evaporators, hot wells, acid sumps, cooling tanks, granulators, dryers, coolers, screens, mills, mixers, curing belts (dens), coolers, and facilities which store run-of-pile triple superphosphate, depending on the type of plant. New facilities include those that commenced construction, modification or reconstruction after the date of proposal. This information is being collected to assure compliance with 40 CFR Part 60, Subpart T, U, V, W, and X. In general, all NSPS standards require initial notifications, performance tests, and periodic reports by the owners/operators of the affected facilities. They are also required to maintain records of the occurrence and duration of any startup, shutdown, or malfunction in the operation of an affected facility, or any period during which the monitoring system is inoperative. These notifications, reports, and records are essential in determining compliance, and are required of all affected facilities subject to NSPS.
