NESHAP for Iron and Steel Foundries (40 CFR Part 63, subpart EEEEE) (Final Rulel)

The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Iron and Steel Foundries (40 CFR Part 63, Subpart EEEEE) were proposed on December 12, 2002, promulgated on April 22, 2004 and amended on May 20, 2005 and February 7, 2008. Amendments to the NESHAP were proposed on October 9, 2019 as a result of the residual risk and technology review (RTR) required under the Clean Air Act (CAA) (as discussed further below). The NESHAP applies to both existing and new iron and steel foundry facilities that are major sources of hazardous air pollutant (HAP) emissions. The rule applies to emissions from metal melting furnaces; scrap pre-heaters; pouring areas; pouring stations; automated conveyor and pallet cooling lines; automated shakeout lines; mold and core making lines; and to fugitive emissions from foundry operations. New facilities include those that commenced construction, modification, or reconstruction after the date of the original proposal (December 12, 2002). This information is being collected to assure compliance with 40 CFR Part 63, Subpart EEEEE. In general, all NESHAP standards require initial notifications, performance tests, and periodic reports by the owners/operators of the affected facilities. They are also required to maintain records of the occurrence and duration of any failures to meet applicable standards, or any period during which the monitoring system is inoperative. Semiannual reporting of these deviations is also required. These notifications, reports, and records are essential in determining compliance, and are required of all affected facilities subject to NESHAP. Any owner/operator subject to the provisions of this part shall maintain a file containing these records and retain the file for at least five years following the generation date of such maintenance reports and records. All reports are sent to the delegated state or local authority. If there is no such delegated authority, the reports are sent directly to the U.S. Environmental Protection Agency (EPA) regional office. The final RTR amendments to the rule eliminate the startup, shutdown, and malfunction (SSM) exemption; remove the SSM plan requirement; add new work practice standards for cupola melting furnaces while off blast; add electronic submittal of notifications, semiannual reports, and performance test reports; and make technical and editorial changes. The remaining portions of the NESHAP remain unchanged.
