NSPS for Metal Coil Surface Coating (40 CFR part 60, subpart TT) (Renewal)

The New Source Performance Standards (NSPS) for Metal Coil Surface Coating (40 CFR Part 60, Subpart TT) were: proposed on January 5, 1981; promulgated on November 1, 1982; and amended on June 24, 1986 and October 17, 2000. These regulations apply to the following surface coating lines in the metal coil surface coating industry: each prime coat operation; each finish coat operation; and each prime and finish coat operation cured simultaneously, where the finish coat is applied wet-on-wet over the prime coat. These regulations apply to facilities commencing construction, modification, or reconstruction after the date of proposal. This information is being collected to assure compliance with 40 CFR Part 60, Subpart TT. In general, all NSPS standards require initial notification reports, 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 NSPS. Any owner/operator subject to the provisions of this part shall maintain a file of these measurements, and retain the file for at least two years following the date of such measurements, maintenance reports, and records. All reports are sent to the delegated state or local authority. In the event that there is no such delegated authority, the reports are sent directly to the U.S. Environmental Protection Agency (EPA) regional office.
