Assessment Topic

Standards of performance for the control of particulate and visible emissions from phosphate rock plants are being promulgated under the authority of Section 111 of the Clean Air Act. These standards apply only to phosphate rock dryers, calciners, grinders and ground rock storage and handling systems for which construction or modification began on or after September 21, 1979. This document contains comments received on the proposed standards and responses to those comments. The promulgated standards will limit particulate emissions from all dryers and from calciners processing unbeneficiated rock to 0.03 and 0.12 kg/Mg, respectively. Particulate emissions from beneficiated rock calciners will be limited to 0.055 kg/Mg. Visible emissions from all dryers and calciners will be limited to 10 percent opacity. Particulate emissions from grinders will be limited to 0.066 kg/Mg with 0 percent opacity. Visible emissions from ground rock storage and handling systems will be limited to 0 percent opacity.
This document provides a summary of comments and responses on the proposed rule and discusses the changes since proposal.
