Hydrochloric Acid Production: National Emission Standards for Hazardous Air Pollutants (NESHAP)

Rule Summary

Hydrochloric acid (HCl) is used in a variety of industrial processes including: refining ore for the production of tin and tantalum, pickling and cleaning of metal products, electroplating, cleaning boilers, neutralizing chemically basic systems, manufacturing fertilizers, dyes, textiles and rubber, and preparing various food products. Hydrochloric acid is also used as a laboratory reagent.

The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Hydrochloric Acid Production were initially proposed in 2001 and finalized in 2003. In this rule, EPA regulates HCl and chlorine emissions from HCl production facilities.
