63, Subpart EEE and the General Provisions under 40 CFR 63, Subpart A. The T-149 

incinerator is located at the Lilly Tippecanoe Laboratories in Lafayette, Indiana. 

The HWC MACT rule requires that Lilly monitor certain operating parameters 

continuously, but not the actual pollutants [metals, particulate matter (PM), and hydrogen 

chloride and chlorine (HCVClz)]. However, Section 63.1209(a)(5) of the HWC MACT allows 

facilities to petition the Administrator under Section 63.8(f) of the General Provisions to use 

continuous emissions monitoring systems (CEMS) for compliance monitoring of particulate 

matter, mercury, semi-volatile metals, low volatile metals, and hydrochloric acid/chlorine gas 

emissions in lieu of complying with corresponding operating parameter limits. In addition, 

Section 63.1209(g) of the HWC MACT allows facilities to submit an application to the 

Administrator to request approval of alternative monitoring requirements to demonstrate 

compliance with operating parameter limits monitored by parametric instruments. 

You are proposing to install and operate CEMS for metals, PM, and HCl to directly 

demonstrate continuous compliance with the semi-volatile metals, low-volatile metals, mercury, 

particulate matter, and HCl/Ch emission limits as an alternative to monitoring operating 

parameter limits that are shown in the attached table. As required by the HWC MACT, you are 

also proposing to install and operate CO and 0 2 CEMS to demonstrate compliance with the CO 

emission limit, corrected to 7 percent oxygen.
