Emissions Compliance Testing of Two Dual Chamber Hospital,Medical,and Infectious
Waste Incinerator Emission Sources ID No. ESO1 and ES02
Proposed Test Dates: Week of April 18,2016
To be performed by TRC Environmental Corporation
Dear Mr. Skrzypczak:
The emissions test protocol for the two subject sources has been reviewed. Incinerators ESO1 and ES02
each controlled respectively in series by: selective non-catalytic reduction(SNCR) system with ammonia
injection ID No. CD07 and CD08,packed bed scrubber and associated quench column ID No. CDO1 and
CD02, with venturi scrubber ID No. CD03 and CD04, and sulfur impregnated carbon bed ID No. CD05
and CD06. Incinerators ESO1 and ES02 are subject to 15A NCAC 2D .1206,Hospital,Medical and
Infectious Waste Incinerators; 15A NCAC 2D .1100 Control of Toxic Air Pollutants; 40 CFR 60 Subpart
Ce Emission Guidelines and Compliance Times for Hospital/Medical/Infectious Incinerators; 40 CFR 60
Subpart Ec Standards of Performance for 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. The
following table lists the pollutants and acceptable test methods for each incinerator to be tested.
Incinerator ESO1 and ES02-Pollutants and Test Methods
Source To
Be Tested Pollutant EPA Method Rum Time Notes
ES01 Concurrent with
and Oxygen and Carbon Dioxide 3A 3 runs, 120 minutes each Method 29
ES02 Visible Emissions 9 3 rums,60 minutes each
ES02 Mercury(Hg) 29 3 rums,120 minutes each
The tester must verify the absence of cyclonic flow as described in Section 11.4 of EPA Method 1.
TRC shall perform a pre-test analysis of the filter blank, following the procedure in EPA Method 29
section 7.2.1. Stericycle must submit to the Division of Air Quality(DAQ)the pretest filter blank
analysis values for each target metal prior to testing. DAQ will not allow any correction to the test results
above the maximum blank correction as specified in EPA Method 29. TRC will also prepare duplicate
Method 29 field blanks for potential analyses by DAQ.

Note that audit sample analysis is required for Methods 29. TRC has submitted an audit sample order
request and the sample must be present for inspection on request during the test period. For additional
information please see this EPA web page htip://www.gpa.gov/ttn/emc/email.html#audit.
Please note that the detection limits for some of the proposed methods are based on actual source
parameters. No estimated detection limits are listed in the protocol. Therefore,the responsibility will
remain with Stericycle and the tester to ensure that the minimum method detection limits will be low
enough to demonstrate compliance with the applicable emissions limits. The result cannot be reported as
zero. The result must be reported as less than the method detection limit determined from the test.
As stated in permit condition 2.2.A"The emission limits in the table below represent total emissions from
both incinerators combined." Therefore,the emission rates of the pollutants listed in the table under
conditions 2.2.A from one unit will be doubled for comparison with these toxic emission limits.
Alternately Stericycle may test both units simultaneously.
The test protocol is approved as represented in the table. Stericycle shall be responsible for ensuring,
within the limits of practicality,that each subject incinerator being tested is operated at or near the
maximum normal waste charge rate(i.e., at or above approximately 90%of the maximum). The
maximum normal waste charge rate for each incinerator is 1,911 pounds per hour. Thus,the proposed
test period waste charge rate of 1,900 pounds per hour is acceptable. The final report must include the
applicable test period monitored parameters data(i.e., incinerator hourly waste charge rate and secondary
chamber temperature)and the control system parameters data(i.e., flue gas temperature, secondary
chamber temperature,NOx reagent injection rate,pressure drop across scrubbers, scrubber liquor flow
rates, scrubber pH and the bypass stack position). The parametric data shall be based on a 3-hour rolling
average calculated each hour as the average of the previous 3 operating hours.
Approval of the proposed methods does not exempt the tester,in any way, from the minimum
requirements of the applicable test methods. Any deviations from the applicable methodologies not
specifically addressed in this letter remains subject to the approval of the Division of Air Quality. If there
are questions concerning this matter,please contact me at(919)707-8415 or greg .on�[e-mail].
