Title: ●Residual Risk and Technology Review Amendments to the Primary Aluminum Reduction NESHAP 
Abstract: The existing National Emission Standard for Hazardous Air Pollutants (NESHAP) for Primary Aluminum Reduction Plants (found in 40 CFR part 63, subpart LL) applies to the owner or operator of each new pitch storage tank or new or existing potline, paste production plant, or anode bake furnace associated with primary aluminum production and located at a major source as defined in 40 CFR section 63.2. The existing subpart LL does not apply to any existing anode bake furnace that is not located on the same site as a primary aluminum reduction plant. Section 112(f)(2) of the CAA directs EPA to conduct risk assessments on each source category subject to maximum achievable control technology (MACT) standards pursuant to a NESHAP and determine if additional standards are needed to protect human health. The section 112(f)(2) residual risk review of a source category is to be performed within 8 years after promulgation of the associated NESHAP. Section 112(d)(6) of the CAA requires EPA to review and revise the MACT standards as necessary taking into account developments in practices, processes, and control technologies. The section 112(d)(6) technology reviews of a NESHAP are to be performed no less often than every 8 years after promulgation of that NESHAP. The NESHAP for Primary Aluminum Reduction Plants was first promulgated in 1997. The amendments will address possible residual risks and advancements in technology.
