5. Title, number of pages and language(s) of the notified document:  National 
Emission Standards for Hazardous Air Pollutants: Integrated Iron and Steel Manufacturing 
Facilities Technology Review; (22 page(s), in English)  
6. Description of content:  Proposed rule - The U.S. Environmental Protection Agency 
(EPA) is proposing amendmen ts to the National Emission Standards for Hazardous Air 
Pollutants (NESHAP) for Integrated Iron and Steel Manufacturing Facilities, as required 
by the Clean Air Act (CAA). To complete the required CAA section 112(d)(6) technology 
review promulgated on 13 J uly 2020, the EPA is proposing standards to regulate HAP 
emissions from five unmeasured fugitive and intermittent particulate (UFIP) sources, 
some of which are also referred to as "fugitive" sources, that are currently not regulated 
by the NESHAP, as follo ws: Bell Leaks, Unplanned Bleeder Valve Openings, Planned 
Bleeder Valve Openings, Slag Pits, and Beaching. Also, for sinter plants we are proposing 
standards for the following five currently unregulated HAP: carbonyl sulfide (COS), carbon 
disulfide (CS2), mercury (Hg), hydrochloric acid (HCl), and hydrogen fluoride (HF); for 
blast furnace (BF) stoves and basic oxygen process furnaces (BOPFs), we are proposing 
standards for the following three unregulated pollutants: total hydrocarbons (THC), HCl, 
and dioxin s/furans (D/F); and for BFs, we are proposing standards for the following two 
unregulated pollutants: THC and HCl. As an update to the technology review, we are 
proposing to revise the current BOPF shop fugitive 20 percent opacity limit to a 5 percent 
opacity limit and require specific work practices; revise the current BF casthouse fugitive 
20 percent opacity limit to a 5 percent opacity limit; and revise the current standards for G/TBT/N/USA/2026  
 
- 2 - 
 
  D/F and polycyclic hydrocarbon (PAH) for sinter plants. We are also proposin g a fenceline 
monitoring requirement for chromium (Cr), including a requirement that if a monitor 
exceeds the proposed Cr action level, the facility will need to conduct a root cause analysis 
and take corrective action to lower emissions. We solicit commen ts on all aspects of this 
proposed action.  
7. Objective and rationale, including the nature of urgent problems where 
applicable:  Protection of the environment; Quality requirements
