Clay Ceramics Manufacturing Area Sources: National Emission Standards for Hazardous Air Pollutants (NESHAP)
On this page:
The Clay Ceramics Manufacturing area source category includes those facilities that process greater than 45 megagrams per year (Mg/yr) (50 tons per year (tpy)) wet clay to manufacture pressed floor tile, pressed wall tile, and other pressed tile; sanitaryware (toilets and sinks); dinnerware; or pottery. Clay ceramics are primarily composed of clay and shale, and may include many different additives, including silica, talc, and various high purity powders produced by chemical synthesis. The key pollutants regulated under this rule are metallic hazardous air pollutants through the control of particulate matter as a surrogate.
