NESHAP for Refractory Products Manufacturing (40 CFR Part 63, Subpart SSSSS) (Final Rule)

The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Refractory Products Manufacturing (40 CFR Part 63, Subpart SSSSS) were proposed on June 20, 2002, and promulgated on April 16, 2003. These regulations apply to each refractory products manufacturing facility which produces refractory bricks, refractory shapes, monolithics, kiln furniture, crucibles, and other materials used as linings for boilers, kilns, and other processing units and equipment where extreme temperature, corrosions, and abrasion would destroy other materials. These regulations apply to existing facilities and new facilities that manufacture refractory products and use organic hazardous air pollutant (HAP), chromium refractory, and clay refractory products. New facilities include those that commenced construction, modification or reconstruction after the date of proposal. This information is being collected to assure compliance with 40 CFR Part 63, Subpart SSSSS. 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.
