## Abstract

This action finalizes amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for the Phosphoric Acid Manufacturing and Phosphate Fertilizer Production source categories. These final amendments are in response to two petitions for reconsideration filed by industry stakeholders on the rule revisions to the NESHAP for the Phosphoric Acid Manufacturing and Phosphate Fertilizer Production source categories that were promulgated on August 19, 2015. We are revising the compliance date by which affected sources must include emissions from oxidation reactors when determining compliance with the total fluoride emission limits for superphosphoric acid (SPA) process lines. In addition, we are revising the compliance date for the monitoring requirements for low-energy absorbers. We are also clarifying one option and adding a new option, to the monitoring requirements for low-energy absorbers.
