### ,, OFFICE OF AIR QUALITY PLANNING AND STANDARDS



## I am writing in response to your request for alternative monitoring described in detail in your Alternative Monitoring Petition (AMP) dated December 2, 2005, whichrequests alternatives to monitoring for Eli Lilly and Company's (Lilly) rotarykiln, solid-liquid incineration system, also known as the T-149 incinerator, that bumshazardous and nonhazardous waste. The T-149 incinerator is subject to the National Emission Standards for Hazardous Air Pollutants from Hazardous Waste Combustors (HWC MACT) rule under40 CFR 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) ofthe HWC MACT allows facilities to petition the Administrator under Section 63.8(f) ofthe General Provisions to use continuous emissions monitoring systems (CEMS) for compliance monitoring ofparticulate matter, mercury, semi-volatile metals, low volatile metals, and hydrochloric acid/chlorine gas emissions in lieu ofcomplying with corresponding operating parameter limits. In

## addition, Section 63.1209(g) ofthe HWC MACT allows facilities to submit an application to the Administrator to request approval ofalternative monitoring requirements to demonstrate compliance with operatingparameter limits monitored byparametric 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/Chemission 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 7percent oxygen.

## 2 Pursuant to Section 60.8(f) ofthe General Provisions of40 CPR 63 and 40 CPR 63.1209(a)(5) ofthe HWC MACT, the U.S. Environmental Protection Agency hereby approves your request for the alternative monitoring approach, associated QA/QC procedures, and the backup monitoring conditions as described in detail in your December 2, 2005 AMP and its associated appendices. The approved alternative monitoring modes and averaging periods are summarized in the enclosed table. This approval is only applicable to the Lilly facility cited above. Ifyou have further questions on this matter, please contact Dan Bivins at (919) 541-5244.

Enclosure Sincerely,
