SUBJECT: Review of 2013 Second Semester CO CEMS Report

Facility ID# 0100010
Air Permit No. 05896T21
Dear Mr. Skrzypczak:
Thank you for your timely submittal of the subject report, dated January 8, 2014. The submittal
also included a relative accuracy test audit, which will be reviewed separately. The excess
emissions report assessed the carbon monoxide (CO) continuous emissions monitoring systems
(CEMS)operating at the Haw River Facility during the second half of 2013. 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 CO emissions standard(40 ppmvd, 7% 02 corrected, 12-hour rolling
average)pursuant to NCAC 2D .1206 and Air Quality Permit No. 05896T21, Specific
Condition 2.1.A.1.h. The quarterly CEMS summaries indicated no exceedances of the CO
emissions standard.
2. Quarterly summary reports were reviewed for compliance with good operation and
maintenance (O&M) practices pursuant to 40 CFR 60.11(d), General Condition 3.17 and
summarized as follows:
Unit Quarter %EE %NW
HMIWI ESO1 3rd 0.0 0.14
4th 0.0 1.41
HMIWI ES02 3rd 0.0 0.05
4th 0.0 0.13

The incinerators, along with associated CEMS units, appear to have operated using good
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.
3. For both incinerators, CO CEMS cylinder gas audits (CGA) results were reviewed with
respect to specifications set forth in Section 5 of 40 CFR Part 60, Appendix F. The quality
assurance (QA)results appear to have met the 15%accuracy specification.
If you should have any questions, please contact me at [phone] or [e-mail].
Sincerely,
