Summary of the Major Provisions

The EPA is finalizing MACT emission limits for non-Hg HAP metals (or PM surrogate) and Hg, and a health-based emission limit (HBEL) for acid gases (hydrogen fluoride (HF), hydrogen chloride (HCl) and chlorine (Cl₂)) for BSCP tunnel kilns…

b. Clay Ceramics Manufacturing NESHAP

The EPA is finalizing MACT emission limits for Hg, PM (surrogate for non-Hg HAP metals), and dioxins/furans and HBEL for acid gases (HF and HCl) for sanitaryware tunnel kilns and ceramic tile roller kilns.

Under the final BSCP Manufacturing NESHAP, the owner or operator is required to measure emissions of HF, HCl, Cl₂, Hg and PM (or non-Hg HAP metals).
