Facing the New Emission Standards for Hydrochloric Acid Pickling
The U.S. Environmental Protection Agency (EPA) has developed a new regulation to reduce hazardous air pollutant (HAP) emissions from facilities that pickle carbon steel using hydrochloric acid (HCl) solution as well as from associated HCl regeneration plants. This regulation, the National Emission Standards for Hazardous Air Pollutants for Steel Pickling – HCl Process Facilities and HCl Acid Regeneration Plants, has a compliance date of June 22, 2001 for existing sources. This paper discusses facilities to which this regulation applies, its requirements, and the various deadlines. The first steps towards demonstrating compliance will also be addressed.
