Title: Portland Cement Risk and Technology Review 
Abstract: This action will address the agency's residual risk and technology review (RTR) of the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Portland Cement Manufacturing. The Portland Cement Manufacturing NESHAP, subpart LLL, initially was promulgated pursuant to section 112(d) of the Clean Air Act (CAA) in 1999. The EPA promulgated the current version of the rule on 9/9/10, with amendments on 2/12/13 and 07/27/15. The NESHAP established emission limitations and work practice requirements based on maximum achievable control technology (MACT) for controlling emissions of hazardous air pollutants (HAP) from kilns, clinker coolers, raw material dryers and finish mills, as well as clinker piles, storage bins, conveying systems, bagging systems, bulk loading and unloading systems. The HAP emitted from kilns and clinker coolers include particulate matter, metals including mercury, volatile organic compounds and hydrogen chloride. This action will implement the residual risk review requirements of CAA section 112(f)(2) and the technology review requirements of CAA section 112(d)(6). The statute directs the EPA to promulgate emission standards under CAA 112(f)(2) if such standards are required to provide an ample margin of safety to protect public health or to prevent, taking relevant factors into account, an adverse environmental effect. Any such standards are to be promulgated within 8 years after promulgation of MACT standards under CAA section 112(d). CAA section 112(d)(6) requires the EPA to review and revise the MACT standards as necessary, taking into account developments in practices, processes and control technologies, no less often than every 8 years. Pursuant to a consent decree, the EPA is obligated to complete this proposed action by 6/15/17. As a result of promulgating the 2013 rule, the EPA estimated benefits would range from $6.7 billion to $18 billion annually, due to reductions in fine particle pollution (PM2.5). This included the value of avoiding 960 to 2,500 premature deaths in people with heart disease. The EPA also estimated the rule would prevent other serious health effects each year, including 17,000 cases of aggravated asthma, 1,500 heart attacks, 650 cases of chronic bronchitis, 1,000 emergency room visits for respiratory problems, such as asthma, 740 hospital admissions for respiratory or cardiovascular problems, 32,000 cases of upper and lower respiratory symptoms, 130,000 days when people miss work and 750,000 days when people must restrict their activities because of particle pollution-related symptoms. This RTR action will assure these continued public health benefits, through further analysis and, if warranted, revisions to the rule.
