In addition, this action finalizes an 8-year review of the current new source performance standards (NSPS) for five source categories. We are also taking final action addressing Clean Air Act (CAA) provisions related to emission standards for hazardous air pollutants, review and revision of emission standards, and work practice standards. The final amendments to the Phosphoric Acid Manufacturing NESHAP include: Numeric emission limits for previously unregulated mercury (Hg) and total fluoride emissions from calciners; work practice standards for hydrogen fluoride (HF) emissions from previously unregulated gypsum dewatering stacks and cooling ponds; clarifications to the applicability and monitoring requirements to accommodate process equipment and technology changes; removal of the exemptions for startup, shutdown, and malfunction (SSM); adoption of work practice standards for periods of startup and shutdown; and revised recordkeeping and reporting requirements for periods of SSM. The final amendments to the Phosphate Fertilizer Production NESHAP include: Clarifications to the applicability and monitoring requirements to accommodate process equipment and technology changes; removal of the exemptions for SSM; adoption of work practice standards for periods of startup and shutdown; and revised recordkeeping and reporting requirements for periods of SSM. The revised NESHAP for Phosphoric Acid Manufacturing facilities will mitigate future increases of Hg emissions from phosphate rock calciners by requiring pollution prevention measures. Further, based on the 8-year review of the current NSPS for these source categories, the EPA determined that no revisions to the numeric emission limits in those rules are warranted. 80 FR 50386 https://www.govinfo.gov/app/details/FR-2015-08-19/2015-19732 2015-19732 fr19au15-12 RIN 2060-AQ20 6560-50-P EPA-HQ-OAR-2012-0522 FRL-9931-01-OAR https://www.govinfo.gov/app/details/FR-2015-08-19/2015-19732 https://www.govinfo.gov/content/pkg/FR-2015-08-19/html/2015-19732.htm https://www.govinfo.gov/content/pkg/FR-2015-08-19/pdf/2015-19732.pdf Environmental Protection Air Pollution Control Fertilizers Fluoride Particulate Matter Phosphate Reporting and Recordkeeping Requirements Administrative Practice and Procedures Hazardous Substances Incorporation by Reference Intergovernmental Relations 75 p. 50386 50460 80 FR 50386 Title 40 Part 60 40 CFR Part 60 Title 40 Part 63 40 CFR Part 63 RIN 2060-AQ20 Phosphoric Acid Manufacturing and Phosphate Fertilizer Production RTR and Standards of Performance for Phosphate Processing; Federal Register Vol. 80, Issue RULE 2015-19732 II ENVIRONMENTAL PROTECTION AGENCY 2015-08-19 EPA-HQ-OAR-2012-0522 FRL-9931-01-OAR 6560-50-P 2015-19732 Final rule.
