View Rule

The Risk and Technology Review (RTR) for the Phosphoric Acid Manufacturing and the Phosphate Fertilizer Production NESHAP were proposed on November 7, 2014 (79 FR 66512) and promulgated on August 19, 2015, (80 FR 50386). On October 15 and 16, 2015, the Fertilizer Institute (TFI) and the Potash Corporation of Saskatchewan (PCS) petitioned the Agency for reconsideration on three issues: the final monitoring requirements for low pressure scrubbers, the compliance date for existing air oxidation reactors, and the final total fluoride emission limit for calciners. On December 3, 2015, the EPA granted reconsideration on these matters and intends to propose a response to the petitions in the fall of 2016.
