What the source says
On July 21, 2015, the Environmental Protection Agency (EPA) issued final amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Phosphoric Acid Manufacturing and Phosphate Fertilizer Production, and to the Standards of Performance (NSPS) for Phosphate Processing. The phosphoric acid manufacturing and phosphate fertilizer production standards were promulgated in 1999 and currently 13 facilities are subject to at least one of the rules. Ten of the 13 facilities are considered to be in both source categories.
