Stericycle, Inc.

Findings

On 12/27/2006 DAQ received a stack test report for the Medical Waste Incinerator. Additional information was received on 2/20/2007. Testing was performed on 10/18/2006 to demonstrate compliance with the emission limits referenced in Permit Condition II.B.4.c and to establish new operating parameters in accordance with Permit Conditions II.B.4.c.1. The DAQ-calculated test results are:

Source Test Date Pollutant Result Limit
Medical Waste Incinerator 10/18/2006 PM 2 mg/dscm @ 7% O2 34 mg/dscm @ 7% O2
    CO 20 ppmdv @ 7% O2 40 ppmdv @ 7% O2
    Dioxin/furan 2 mg/dscm @ 7% O2 125 mg/dscm @ 7% O2
    Dioxin/furan (TEQ) 0.1 mg/dscm @ 7% O2 2.3 mg/dscm @ 7% O2
    HCl 6 ppmdv @ 7% O2 100 ppmdv @ 7% O2
    SO2 6 ppmdv @ 7% O2 55 ppmdv @ 7% O2
    NOX 250 ppmdv @ 7% O2 250 ppmdv @ 7% O2
    Pb 0.004 mg/dscm @ 7% O2 1.2 mg/dscm @ 7% O2
    Cd 0.001 mg/dscm @ 7% O2 0.16 mg/dscm @ 7% O2
    Hg 0.004 mg/dscm @ 7% O2 0.55 mg/dscm @ 7% O2

A three-hour VEO of stack emissions was performed during the stack test. No opacities were observed.

Operating parameters established during test:

Max.Charge Rate: 1,985.1 lb/hr

Min. Secondary Chamber Temperature: 1,797.6 F

Max. Reactor Inlet Temperature: 408 F

Min. Carbon Injection Rate: 2.85 lb/hr

Min. Scrubber Liquor Flow Rate: 62.1 lb/hr

Min. Scrubber Liquor pH: 5.98
