NESHAP for Steel Pickling, HCI Process Facilities and Hydrochloric Acid Regeneration Plants (40 CFR Part 63, Subpart CCC) (Renewal)

The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Steel Pickling, HCl Process Facilities and Hydrochloric Acid Regeneration Plants (40 CFR Part 63, Subpart CCC) were proposed on September 18, 1997; promulgated on June 22, 1999; and amended on both September 19, 2012 and November 19, 2020. This rule applies to all facilities that pickle steel using hydrochloric acid (HCl) or regenerate hydrochloric acid and are either major sources or part of a facility that is a major source. This information is being collected to assure compliance with 40 CFR Part 63, Subpart CCC. 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.
