Dear Mr. Skrzypczak:
Thank you for your timely submittal of the subject report, received February 2, 2017. The excess
emissions report assessed the carbon monoxide (CO)/oxygen(02) continuous emissions
monitoring systems (CEMS) operating at the Haw River Facility during the second half of 2016.
The CEMS was 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 rolling average) as stated in Air Permit No. 05896, Specific
Condition 2.1.A.La. 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 3rd 0.0 0.0
4th 0.0 0.1
HMIWI ES02 3rd 0.0 0.0
4th 0.0 0.1
The incinerators, along with associated CEMS units, appear to have operated using proper
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.2.6i.
