NR 666.104
NR 666.104 Standards to control organic emissions. NR 666.104(1)(a)(a) General. Except as provided in par.
(c), a boiler or industrial furnace burning hazardous waste shall achieve a destruction and removal efficiency (DRE) of 99.99% for all organic hazardous constituents in the waste feed. To demonstrate conformance with this requirement, 99.99% DRE shall be demonstrated during a trial burn for each principal organic hazardous constituent (POHC) designated (under par.
(b)) in its license for each waste feed. DRE is determined for each POHC from the following equation:
where:
Win = Mass feed rate of one principal organic hazardous constituent (POHC) in the hazardous waste fired to the boiler or industrial furnace
Wout = Mass emission rate of the same POHC present in stack gas prior to release to the atmosphere
NR 666.104(1)(b)
(b) Designation of POHCs. Principal organic hazardous constituents (POHCs) are those compounds for which compliance with the DRE requirements shall be demonstrated in a trial burn in conformance with procedures prescribed in s.
NR 670.066. One or more POHCs shall be designated by the department for each waste feed to be burned. POHCs shall be designated based on the degree of difficulty of destruction of the organic constituents in the waste and on their concentrations or mass in the waste feed considering the results of waste analyses submitted with the feasibility and plan of operation report. POHCs are most likely to be selected from among those compounds listed in ch.
NR 661 Appendix VIII that are also present in the normal waste feed. However, if the applicant demonstrates to the department's satisfaction in writing that a compound not listed in ch.
NR 661 Appendix VIII or not present in the normal waste feed is a suitable indicator of compliance with the DRE requirements, that compound may be designated as a POHC. Such POHCs need not be toxic or organic compounds.
NR 666.104(1)(c)
(c) Dioxin-listed waste. A boiler or industrial furnace burning hazardous waste containing (or derived from) EPA hazardous waste numbers F020, F021, F022, F023, F026 or F027 shall achieve a destruction and removal efficiency (DRE) of 99.9999% for each POHC designated (under par.
(b)) in its license. This performance shall be demonstrated on POHCs that are more difficult to burn than tetra-, penta- and hexachlorodibenzo-
p-dioxins and dibenzofurans. DRE is determined for each POHC from the equation in par.
(a). In addition, the owner or operator of the boiler or industrial furnace shall notify the department of intent to burn EPA hazardous waste numbers F020, F021, F022, F023, F026 or F027.
NR 666.104(1)(d)
(d) Automatic waiver of DRE trial burn. Owners and operators of boilers operated under the special operating requirements provided by s.

NR 666.104(1)(e)
(e) Low risk waste. Owners and operators of boilers or industrial furnaces that burn hazardous waste in compliance with s.
NR 666.109 (1) are considered to be in compliance with the DRE standard of par.
(a) and are exempt from the DRE trial burn.
NR 666.104(2)(a)
(a) Except as provided in sub.
(3), the stack gas concentration of carbon monoxide (CO) from a boiler or industrial furnace burning hazardous waste cannot exceed 100 ppmv on an hourly rolling average basis (i.e., over any 60 minute period), continuously corrected to 7% oxygen, dry gas basis.
NR 666.104(2)(b)
(b) CO and oxygen shall be continuously monitored in conformance with “Performance Specifications for Continuous Emission Monitoring of Carbon Monoxide and Oxygen for Incinerators, Boilers and Industrial Furnaces Burning Hazardous Waste" in ch.
