Carbon Black Production Area Sources: National Emission Standards for Hazardous Air Pollutants (NESHAP)
The Carbon Black Production area source category includes any facility that produces carbon black by the furnace black process, thermal black process, or the acetylene decomposition process, but at an emissions rate of 10 tons per year for one hazardous air pollutant (HAP), or 25 tons per year of combined HAPs.
Carbon black is used primarily as a reinforcing agent for rubber, utilized largely in the manufacturing of automotive tires. It is also used as a colorant in inks, paints, plastics, and paper. The primary hazardous air pollutant (HAP) emitted and controlled from carbon black facilities is benzene, but other organic HAP may be present.
