SUBJECT: Review of 2011 CO CEMS Semiannual Report
Stericycle, Inc. —Haw River Facility
Haw River, Alamance County, North Carolina
Facility ID# 0100010; Air Permit No. 05896T19
Dear Mr. Skrzypczak:
Thank you for your timely submittal of the subject report, dated January 26, 2012. The report
assessed the carbon monoxide (CO) continuous emissions monitoring systems (CEMS) operating
at the Haw River Facility during the second half of 2011. The Division of Air Quality (DAQ) has
completed its review and offers the following comments:
1. Although your submittal included summaries of CEMS performance during the third and
fourth quarter of 2011,our review focused on CEMS data occurring after November 15,
2011. This was the effective date that DAQ certified the CO CEMS on ES02; ES01 was
certified effective November 16, 2011.
2. Hospital, medical and infectious waste incinerators (HMIWI) ES01 & 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. 05896T19, Specific
Condition 2.1.A.l.h. The CEMS summaries indicated compliance with the CO emissions
standard.
3. The report was also reviewed for compliance with good operation and maintenance (O&M)
practices pursuant to 40 CFR 60.11(d) and General Condition 3.F.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.
