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

Resumo

The EPA is proposing 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). This action proposes to amend specific provisions in the NESHAP to resolve issues and questions raised after promulgation of the NESHAP. The proposed amendments would revise the emissions limit for phosphate rock calciners and clarify several provisions regarding parameter monitoring and the applicability of the general provisions. In the Rules and Regulations section of this Federal Register, we are making the corrections in a direct final rule, without prior proposal, because we view the revisions as noncontroversial, and we anticipate no adverse comments. We have explained our reasons for the corrections in the preamble to the direct final rule. If we receive no adverse comments, we will take no further action on this proposed rule. If we receive adverse comments, we will publish a timely withdrawal of the direct final rule in the Federal Register. All public comments will be addressed
