National Emission Standards for Hazardous Air Pollutants From Phosphoric Acid Manufacturing Plants and Phosphate Fertilizers Production Plants

Özet

The EPA is taking direct final action to amend the national emission standards for hazardous air pollutants (NESHAP) for phosphoric acid manufacturing plants and the NESHAP for phosphate fertilizers production plants which were promulgated on June 10, 1999 under authority of section 112 of the Clean Air Act (CAA). The NESHAP apply to owners and operators of phosphoric acid and phosphate fertilizers production facilities that are major sources of hazardous air pollutants (HAP). The EPA is amending specific provisions in the NESHAP to resolve issues and questions raised after promulgation of the final rules. The amendments do not significantly change EPA's original projections for the environmental benefits, compliance costs, and burden on industry, and do not affect the number of affected facilities.
