SUBJECT: Review of 2018 Semiannual CO/02 CEMS Report, First Half
Stericycle, Inc. —Haw River Facility
Haw River, Alamance County,North Carolina
Air Permit No. 05896T25
Facility ID No. 0100010
Dear Mr. Skrzypczak:
Thank you for your timely submittal of the subject report, received July 31, 2018. 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 2018.
The CEMS were installed pursuant to 15A NCAC 02D .1206—Hospital, Medical, and Infectious
Waste Incinerators. The Division of Air Quality(DAQ) has completed its review and has 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 block average) as indicated in Air Permit No. 05896, Specific
Condition 2.1.A.2.a and 2.1.A.2.t. There were no exceedances reported during this time
period.
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 0.00 0.00
2nd 0.58 0.65
HMIWI ES02 1 st 0.00 0.34
2nd 0.00 0.00

The incinerators and associated CO/02 CEMS appear to have operated using good O&M
practices for minimizing emissions 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.
3. Quarterly CO/02 CEMS cylinder gas audits (CGA)were reviewed for each incinerator. The
quality assurance (QA) results appear to have met the 15% accuracy requirement of 40 CFR
Part 60, Appendix F—Quality Assurance Procedures, referenced in Specific Condition
2.1.A.21ii.
If you should have any questions,please contact me at 919-707-8493 or [e-mail].
