This action establishes a final national air toxics rule for hydrochloric acid process steel pickling facilities and hydrochloric acid regeneration plants. This fact sheet explains the rule in "plain language".
Major source facilities subject to the rule emit hydrochloric acid (HCl), a hazardous air pollutant (HAP). In addition, hydrochloric acid regeneration plants also emit chlorine (Cl ), which is also a HAP.
The final rule provides public health protection by requiring new or existing pickling lines that use hydrochloric acid as the primary pickling solution, hydrochloric acid regeneration plants, and acid storage tanks to reduce their HAP emissions via application of the maximum achievable control technology (MACT). Implementation of the rule is expected to reduce HAP emissions by more than 2,500 tons per year (tpy) from current levels.
