National Emission Standards for Hazardous Air Pollutants - Ferroalloys Production (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the National Emission Standards for Hazardous Air Pollutants - Ferroalloys Production (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 This action sets forth the Environmental Protection Agency's (EPA's) final decision on the issues for which it announced reconsideration on July 12, 2016, that pertain to certain aspects of the June 30, 2015, final amendments for the Ferroalloys Production source category regulated under national emission standards for hazardous air pollutants (NESHAP). The EPA is amending the rule to allow existing facilities with positive pressure baghouses to perform visible emissions monitoring twice daily as an alternative to installing and operating bag leak detection systems (BLDS) to ensure the baghouses are operating properly. In addition, this final action explains that EPA is maintaining the requirement that facilities must use a digital camera opacity technique (DCOT) method to demonstrate compliance with opacity limits. However, this final action revises the rule such that it references the recently updated version of the DCOT method. In this action, the EPA also explains that no changes are being made regarding the rule provision that requires quarterly polycyclic aromatic hydrocarbons (PAH) emission testing for furnaces producing ferromanganese (FeMn) with an opportunity for facilities to request decreased compliance test frequency from their permitting authority after the first year. Furthermore, in this action, the EPA is denying the request for reconsideration of the PAH emission limits for both FeMn and silicomanganese (SiMn) production furnaces.

Air Quality State Implementation Plans - Approvals and Promulgations - Ferroalloys Production - National Emissions Standards for Hazardous Air Pollutants (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Air Quality State Implementation Plans - Approvals and Promulgations - Ferroalloys Production - National Emissions Standards for Hazardous Air Pollutants (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 This action finalizes the residual risk and technology review (RTR) conducted for the Ferroalloys Production source category regulated under national emission standards for hazardous air pollutants (NESHAP). These final amendments include revisions to particulate matter (PM) standards for electric arc furnaces, metal oxygen refining processes, and crushing and screening operations, and expand and revise the requirements to control process fugitive emissions from furnace operations, tapping, casting, and other processes. We are also finalizing opacity limits, as proposed in 2014. However, regarding opacity monitoring, in lieu of Method 9, we are requiring monitoring with the digital camera opacity technique (DCOT). Furthermore, we are finalizing emissions standards for four previously unregulated hazardous air pollutants (HAP): Formaldehyde, hydrogen chloride (HCl), mercury (Hg) and polycyclic aromatic hydrocarbons (PAH). Other requirements related to testing, monitoring, notification, recordkeeping, and reporting are included. This rule is health protective due to the revised emissions limits for the stacks and the requirement of enhanced fugitive emissions controls that will achieve significant reductions of process fugitive emissions, especially manganese.

Revision of Source Category List for Standards Under Section 112(k) of the Clean Air Act - and National Emission Standards for Hazardous Air Pollutant (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Revision of Source Category List for Standards Under Section 112(k) of the Clean Air Act - and National Emission Standards for Hazardous Air Pollutant (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 EPA is revising the area source category list by changing the name of the ferroalloys production category to clarify that it includes all types of ferroalloys. We are also adding two additional products (calcium carbide and silicon metal) to the source category. EPA is issuing final national emissions standards for control of hazardous air pollutants (HAP) for area source ferroalloys production facilities. The final emissions standards for new and existing sources reflect EPA's determination regarding the generally available control technology (GACT) or management practices for the source category.

National Emission Standards for Hazardous Air Pollutants for Iron and Steel Foundries (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the National Emission Standards for Hazardous Air Pollutants for Iron and Steel Foundries (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 EPA is issuing amendments to the national emission standards for hazardous air pollutants (NESHAP) for iron and steel foundries. These final amendments add alternative compliance options for cupolas at existing foundries and clarify several provisions to increase operational flexibility and improve understanding of the final rule requirements.

National Emission Standards for Hazardous Air Pollutants for Secondary Aluminum Production (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the National Emission Standards for Hazardous Air Pollutants for Secondary Aluminum Production (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 This action finalizes the residual risk and technology review (RTR), and the rule review, we conducted for the Secondary Aluminum Production source category regulated under national emission standards for hazardous air pollutants (NESHAP). In this action, we are finalizing several amendments to the NESHAP based on the rule review. These final amendments include a requirement to report performance testing through the Electronic Reporting Tool (ERT); provisions allowing owners and operators to change furnace classifications; requirements to account for unmeasured emissions during compliance testing for group 1 furnaces that do not have add-on control devices; alternative compliance options for the operating and monitoring requirements for sweat furnaces; compliance provisions for hydrogen fluoride; provisions addressing emissions during periods of startup, shutdown, and malfunction (SSM); and other corrections and clarifications to the applicability, definitions, operating, monitoring and performance testing requirements. These amendments will improve the monitoring, compliance and implementation of the rule.

National Emission Standards for Hazardous Air Pollutants for Iron and Steel Foundries Area Sources (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the National Emission Standards for Hazardous Air Pollutants for Iron and Steel Foundries Area Sources (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 EPA is issuing national emission standards for hazardous air pollutants for two area source categories (iron foundries and steel foundries). The requirements for the two area source categories are combined in one subpart. The final rule establishes different requirements for foundries based on size. Small area source foundries are required to comply with pollution prevention management practices for metallic scrap, the removal of mercury switches, and binder formulations. Large area source foundries are required to comply with the same pollution prevention management practices as small foundries in addition to emissions standards for melting furnaces and foundry operations. The final standards reflect the generally achievable control technology and/or management practices for each subcategory.
