NESHAP for Secondary Aluminum Production (40 CFR part 63, subpart RRR) (Renewal)

The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Secondary Aluminum Production (40 CFR Part 60, Subpart RRR) were proposed on February 11, 1999, promulgated on March 23, 2000, and amended on the following dates: December 30, 2002 (67 FR 79808); September 3, 2004 (69 FR 53980); October 3, 2005 (70 FR 57513); December 19, 2005 (70 FR 75320); September 18, 2015 (80 FR 56700); and June 13, 2016 (81 FR 38085). These regulations apply to secondary aluminum production facilities that are major sources of hazardous air pollutants (HAP) either commencing construction, or reconstruction, after the date of proposal. This includes facilities that operate aluminum scrap shredders, thermal chip dryers, scrap dryers/delacquering kilns/decoating kilns, group 1 furnaces, group 2 furnaces, sweat furnaces, dross only furnaces, rotary dross coolers, and secondary aluminum processing units (SAPUs). The SAPUs include group 1 furnaces and in-line fluxers. The regulations also apply to secondary aluminum production facilities that are area sources of HAP only with respect to emissions of dioxins/furans (D/F) from thermal chip dryers, scrap dryers/delacquering kilns/decoating kilns, group 1 furnaces, sweat furnaces, and SAPUs. New facilities include those that commenced construction, or reconstruction after the date of proposal. This information is being collected to assure compliance with 40 CFR Part 63, Subpart RRR. The 2015 rule amendments included 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. The 2016 rule amendments amended the 2015 rule to clarify requirements for initial performance tests and submittal of malfunction reports, provide an additional option for group 1 furnaces to account for unmeasured emissions during compliance testing, clarify what constitutes a change in furnace operating mode, and updates the Web addresses for the EPAs Electronic Reporting Tool (ERT) and Compliance and Emissions Data Reporting Interface (CEDRI). This ICR package consolidates the burden associated with the 2015 rule, which is currently approved under OMB Control Number 2060-0683, with this ICR. 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 startup, shutdown, or malfunction in the operation of an affected facility, or any period during which the monitoring system is inoperative. These notifications, reports, and records are essential in determining compliance, and are required of all affected facilities subject to NESHAP.
