SUBJECT: Review of 2015 First Semester CO CEMS Report
Stericycle, Inc. —Haw River Facility
Haw River,Alamance County,North Carolina
Air Pen-nit No. 05896T22
Facility ID# 0100010
Dear Mr. Skrzypczak:
Thank you for your timely submittal of the subject report, dated July 23, 2015. The excess
emissions report assessed the carbon monoxide (CO)/oxygen (02) continuous emissions
monitoring systems (CEMS) operating at the Haw River Facility during the first half of 2015. We
requested and received additional clarification from you via email concerning excess emissions of
CO during startup. The Division of Air Quality(DAQ)has completed its review and offers the
following comments:
1. Hospital, medical, and infectious waste incinerators (HMIWI) ESO1 & ES02 were reviewed for
compliance with the state-only CO emissions limit of 11 parts per million by volume(ppmv,
7% 02, 12-hour rolling average) as stated in Air Pen-nit No. 05896, Specific Condition
2.1.A.La. Although there were no exceedances reported for ESO1 during this time period, there
were nine (9) exceedances reported for ES02. All CO exceedances occurred during incinerator
startup on January 11, 2015, with a maximum 12-hour average of 14.41 ppmv. The report
indicated the startup for ES02 was extended [no waste was incinerated] until the elevated
12-hour CO average had cleared. Based on the above facts and the current permit monitoring
condition, no further action will be taken.
2. Quarterly summary reports were reviewed for compliance with good operation and maintenance
(O&M) practices pursuant to 15A NCAC 02D .0611(d), General Condition 3.F, and
summarized as follows:
Unit Quarter %EE %MD
HMIWI ESO1 1st 0.0 0.1
2nd 0.0 0.0

Unit Quarter %EE I %MD
HMIWI ES02 1 st 0.5 0.2
2nd 0.0 0.0
The incinerators, along with associated CEMS units, appear to have operated using proper
O&M practices since quarterly percent excess emissions (%EE) and percent monitor downtime
(%MD) were less than 6% for any single calendar quarter and less than 3% for two consecutive
quarters.
If you should have any questions, please contact me at 919-707-8493 or [e-mail].
Sincerely,
Alan Drake, Environmental Engineer
