Environmental Protection Agency: National Emission Standards for Hazardous Air Pollutants: Integrated Iron and Steel Manufacturing Facilities Technology Review

Highlights

GAO reviewed the Environmental Protection Agency's (EPA) new rule entitled "National Emission Standards for Hazardous Air Pollutants: Integrated Iron and Steel Manufacturing Facilities Technology Review." GAO found that the final rule (1) finalizes amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Integrated Iron and Steel Manufacturing Facilities to regulate hazardous air pollutant (HAP) emissions from five unmeasured fugitive and intermittent particulate (UFIP) sources previously not regulated by the NESHAP, as follows: Bell Leaks, Unplanned Bleeder Valve Openings, Planned Bleeder Valve Openings, Slag Pits, and Beaching; (2) finalizes standards for sinister plants for five previously unregulated HAPs: carbonyl sulfide (COS), carbon disulfide (CS2), mercury (Hg), hydrochloric acid (HCl), and hydrogen fluoride (HF); (3) finalizes standards for blast furnace (BF) stoves and basic oxygen process furnaces (BOPFs) primary control devices for three previously unregulated pollutants: total hydrocarbons (THCs) (as a surrogate for non-dioxin and non-furan organic HAPs), HCl, and dioxins/furans (D/Fs); (4) finalizes standards for primary control devices for two previously unregulated pollutants: THCs (as a surrogate for non-dioxin and non-furan organic HAPs) and HCl; (5) finalizes (a) work practice standards for the BOPF shops; (b) a requirement that facilities conduct Method 9 readings twice per month at the BOPF shop and BF casthouse; and (c) revised standards for D/Fs and polycyclic aromatic hydrocarbons (PAHs) for sinter plants as an update to the technology review for this source category; and (6) finalizes a fenceline monitoring requirement for total chromium (Cr), including a requirement that if a monitor exceeds a Cr action level, the facility will need to conduct a root cause analysis and take corrective action to lower emissions.

Enclosed is our assessment of EPA's compliance with the procedural steps required by section 801(a)(1)(B)(i) through (iv) of title 5 with respect to the rule. If you have any questions about this report or wish to contact GAO officials responsible for the evaluation work relating to the subject matter of the rule, please contact Charlie McKiver, Assistant General Counsel, at (202) 512-5992.
