## Abstract

This action promulgates national emission standards for each new or existing potline, paste production plant, and anode bake furnace associated with a primary aluminum reduction plant, and for each new pitch storage tank associated with a primary aluminum production plant. In addition, the new source performance standard for primary aluminum plants is amended and most of the requirements are incorporated in the final national emission standards. This action also adds Method 315 for the measurement of extractable organic matter to appendix A of part 63 and Method 14A for the measurement of total fluoride (TF) to appendix A of part 60. The major hazardous air pollutants (HAPs) emitted by the facilities covered by this rule include hydrogen fluoride (HF) and polycyclic organic matter (POM). Polycyclic aromatic hydrocarbons (PAHs) are included in the chemical group POM. Polycyclic aromatic hydrocarbons have been reported to produce carcinogenic, reproductive, and developmental effects as well as toxic effects on blood, the liver, eyes, and the immune system. The final rule will result in a 50 percent reduction in fluoride and POM emissions from the current level of 11,000 tons per year (tpy); a substantial reduction in emissions of nonHAP pollutants, such as particulate matter, also will be achieved. These standards implement section 112(d) of the Clean Air Act as amended (the Act) and are based on the Administrator's determination that primary aluminum plants may reasonably be anticipated to emit several of the HAPs listed in section 112(b) of the Act from the various process operations found within the industry.
