Dear Mr. Yarbrough:
On January 6, 2022 this office received a letter from Don Nuss detailing an incident that occurred
at the above referenced facility. Per the correspondence,the facility experienced an event on December
31, 2021,with a total duration of 6 minutes during which the control system for one of the hospital,
medical, and infectious waste incinerators (HMIWI) (Emission Source ID No. ESO1)was bypassed twice.
The bypass was caused by an electrical short in wiring in the conduit next to the feed hopper, which
resulted in a tripped programmable logic controller(PLC), causing the bypass stack to open for three
minutes. Following initial investigation,personnel attempted to reset the braker,which tripped again and
caused the bypass stack to open for three additional minutes.
This bypass stack event is a violation of 15A NCAC 2D .1206"Hospital, Medical, and Infectious
Waste Incinerators"as referenced by Condition 2.1.A.2.o of Air Quality Permit 05896T25. Per 2D

of Performance for New Stationary Sources: Hospital/Medical/Infectious Waste Incinerators."Per 40
CFR 60.56c(f)(6), "Use of the bypass stack shall constitute a violation of the PM, dioxin/furan, HCI,Pb,
Cd and Hg emission limits." The facility previously received Notices of Violation on November 9, 2021,
