Subject: Stericycle,Inc.
Haw River,Alamance County,North Carolina
Air Permit No.05896T25,Facility ID 01-00010
Emissions Testing of ESO1 and ES02
Performed April 10 and 11,2018 by TRC Environmental Corporation(TRC)
DAQ Tracking No. 2018-044ST
TRC performed EPA Method 29 for lead(Pb),cadmium(Cd), and mercury(Hg),EPA Method 5 for
filterable particulate matter(PM),EPA Method 26A for hydrogen chloride(HC1),and EPA Method 9 for
visible emissions from ESOI and ES02. The test results indicate compliance with the applicable limits.
ESO1 and ES02 are two dual chamber,natural gas-fired hospital,medical,and infectious waste
incinerators. Each incinerator is controlled respectively in series by: selective non-catalytic reduction
(SNCR) system with ammonia or urea injection(ID No. CD07 and CD08),packed bed scrubber and
associated quench column(ID No. CD01 and CD02),with venturi scrubber(ID No.CD03 and CD04),
and sulfur impregnated carbon bed(ID No. CD05 and CD06).
15A NCAC 2D .I 100 Control of Toxic Air Pollutants, 15A NCAC 2D .1206 Hospital,Medical and
Infectious Waste Incinerators,40 CFR 60 Subpart Ce Emission Guidelines and Compliance Times for
Hospital/Medical/Infectious Incinerators, 40 CFR 60 Subpart Ec Standards of Performancefor
Hospital/Medical/Infectious Incinerators for Which Construction is Commenced After June 20, 1996 and
40 CFR 62 Subpart HHH Federal Plan Requirements for Hospital/Medical/Infectious Incinerators
Constructed on or Before June 20, 1996 apply. The tables on the next page present ESO1 and ES02
emissions test results.
The permit states the maximum charge rate for both incinerators is 1870.0 lb/hr. The maximum charge
rate during testing was 1704.6 lb/hr for ESO1 and 1704.71b/hr for ES02. The Pb,Cd,Hg, filterable PM,
HCI,and visible emissions test results are acceptable for ESO1 and ES02. If there are any questions
regarding this review,please contact me for further clarification at(919)707-8427 or
