NESHAP for Carbon Black, Ethylene, Cyanide, and Spandex (40 CFR Part 63, Subpart YY) (Renewal)

The National Emission Standards for Hazardous Air Pollutants (NESHAP) for the regulations published at 40 CFR Part 63, Subpart YY were promulgated on July 12, 2002 (67 FR 46257), and amended on April 13, 2005 (70 FR 19266), July 6, 2020 (85 FR 40386), and November 19, 2020 (85 FR 73854). These regulations apply to existing and new carbon black, cyanide, ethylene, and spandex facilities that would be subject to the major source provisions specified under the Generic Maximum Achievable Control Technology (GMACT) NESHAP. A Risk and Technology Review (RTR) for ethylene production was proposed on October 9, 2019 and promulgated on July 6, 2020 (85 FR 40386). The RTR amendments to the ethylene production regulations corrected and clarified regulatory provisions related to emissions during periods of startup, shutdown, and malfunction; added requirements for electronic reporting of performance test results; added operational requirements for flares; added standards and monitoring requirements for pressure relief devices (PRDs); added requirements and clarifications for vent control bypasses, including bypass lines, in situ sampling systems, maintenance activities, and certain gaseous streams routed to a fuel gas system; added requirements for storage vessel degassing; and revised requirements for heat exchange systems. An RTR amendment for carbon black production (OMB Number 2060-0738, EPA ICR Number 2677.02) was finalized on November 19, 2021 (86 FR 66096) and an RTR amendment for cyanide production (OMB Number 2060-0739, EPA ICR Number 2678.02) was finalized on November 19, 2021 (86 FR 66096). The burden for these requirements is not included in this renewal. 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 YY for ethylene and spandex production facilities. NESHAP standards require initial notifications, performance tests, and periodic reports by the owners/operators of the affected facilities. They must also 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.
