SUBJECT: Review of 2012 Second Semester CO CEMS Report

Air Permit No. 05896T20
Dear Mr. Skrzypczak:
Thank you for your timely submittal of the subject report,received January 21, 2013. The report
assessed the carbon monoxide (CO) continuous emissions monitoring systems (CEMS) operating
at the Haw River Facility during the second half of 2012. 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. 05896T20, Specific
Condition 2.1.A.1.h. The quarterly CEMS summaries indicated no exceedances of the CO
emissions standard.
2. Quarterly summary reports were also reviewed for compliance with good operation and
maintenance (O&M) practices pursuant to 40 CFR 60.11(d) and General Condition 31. 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.
