NR 666.103(1)(e)1.a.a. The hazardous waste shall be fed at a location where combustion gas temperatures are at least 1800 °F. NR 666.103(1)(e)1.b.b. The owner or operator shall determine that adequate oxygen is present in combustion gases to combust organic constituents in the waste and retain documentation of such determination in the facility record. NR 666.103(1)(e)2.2. ‘Burning hazardous waste solely as an ingredient.’ A hazardous waste is burned for a purpose other than solely as an ingredient if it meets one of these criteria: NR 666.103(1)(e)2.a.a. The hazardous waste has a total concentration of nonmetal compounds listed in ch. NR 661 Appendix VIII, exceeding 500 ppm by weight, as-fired, and so is considered to be burned for destruction. The concentration of nonmetal compounds in a waste as-generated may be reduced to the 500 ppm limit by bona fide treatment that removes or destroys nonmetal constituents. Blending for dilution to meet the 500 ppm limit is prohibited and documentation that the waste has not been impermissibly diluted shall be retained in the facility record. NR 666.103(1)(e)2.b.b. The hazardous waste has a heating value of 5,000 Btu/lb or more, as-fired, and so is considered to be burned as fuel. The heating value of a waste as-generated may be reduced to below the 5,000 Btu/lb limit by bona fide treatment that removes or destroys organic constituents. Blending to augment the heating value to meet the 5,000 Btu/lb limit is prohibited and documentation that the waste has not been impermissibly blended shall be retained in the facility record. NR 666.103(1)(f)(f) Restrictions on burning hazardous waste that is not a fuel. Prior to certification of compliance under sub. (3), owners and operators may not feed hazardous waste that has a heating value less than 5,000 Btu/lb, as-generated, (except that the heating value of a waste as-generated may be increased to above the 5,000 Btu/lb limit by bona fide treatment; however, blending to augment the heating value to meet the 5,000 Btu/lb limit is prohibited and records shall be kept to document that impermissible blending has not occurred) in a boiler or industrial furnace, except that: NR 666.103(1)(f)2.2. Hazardous waste may be burned for purposes of compliance testing (or testing prior to compliance testing) for a total period of time not to exceed 720 hours. NR 666.103(1)(f)3.3. Such waste may be burned if the department has documentation to show that, prior to August 21, 1991, all of the following conditions were met: NR 666.103(1)(f)3.a.a. The boiler or industrial furnace was operating under the interim license standards for incinerators provided by subch. O of ch. NR 665, or the interim license standards for thermal treatment units provided by subch. P of ch. NR 665. NR 666.103(1)(f)3.c.c. Hazardous waste with a heating value less than 5,000 Btu/lb was burned prior to that date. NR 666.103(1)(f)4.4. Such waste may be burned in a halogen acid furnace if the waste was burned as an excluded ingredient under s. NR 661.0002 (5) prior to February 21, 1991 and documentation is kept on file supporting this claim. NR 666.103(1)(g)(g) Direct transfer to the burner. If hazardous waste is directly transferred from a transport vehicle to a boiler or industrial furnace without the use of a storage unit, the owner and operator shall comply with s. NR 666.111. NR 666.103(2)(a)(a) General. The owner or operator shall provide complete and accurate information specified in par. (b) to the department on or before August 21, 1991, and shall establish limits for the operating parameters specified in par. (c). Such information is termed a “certification of precompliance” and constitutes a certification that the owner or operator has determined that, when the facility is operated within the limits specified in par. (c), the owner or operator believes that, using best engineering judgment, emissions of particulate matter, metals, HCl and Cl2 are not likely to exceed the limits provided by ss. NR 666.105, 666.106 and 666.107. The facility may burn hazardous waste only under the operating conditions that the owner or operator establishes under par. (c) until the owner or operator submits a revised certification of precompliance under par. (h) or a certification of compliance under sub.(3), or until a license is issued. NR 666.103(2)(b)(b) Information required. All of the following information shall be submitted with the certification of precompliance to support the determination that the limits established for the operating parameters identified in par.(c) are not likely to result in an exceedance of the allowable emission rates for particulate matter, metals, HCl and Cl2: NR 666.103(2)(b)1.c.c. Description of boilers and industrial furnaces burning hazardous waste, including type and capacity of device. NR 666.103(2)(b)1.d.d. A scaled plot plan showing the entire facility and location of the boilers and industrial furnaces burning hazardous waste. NR 666.103(2)(b)1.e.e. A description of the air pollution control system on each device burning hazardous waste, including the temperature of the flue gas at the inlet to the particulate matter control system. NR 666.103(2)(b)2.2. Except for facilities complying with the Tier I or adjusted Tier I feed rate screening limits for metals or total chlorine and chloride provided by ss. NR 666.106 (2) or (5) and 666.107 (2) (a) or (5), respectively, the estimated uncontrolled (at the inlet to the air pollution control system) emissions of particulate matter, each metal controlled by s. NR 666.106, and hydrogen chloride and chlorine, and all of the following information to support such determinations: NR 666.103(2)(b)2.a.a. The feed rate (lb/hr) of ash, chlorine, antimony, arsenic, barium, beryllium, cadmium, chromium, lead, mercury, silver and thallium in each feedstream (hazardous waste, other fuels, industrial furnace feedstocks). NR 666.103(2)(b)2.b.b. The estimated partitioning factor to the combustion gas for the materials identified in subd. 2. a. and the basis for the estimate and an estimate of the partitioning to HCl and Cl2 of total chloride and chlorine in feed materials. To estimate the partitioning factor, the owner or operator shall use either best engineering judgment or the procedures specified in ch. NR 666 Appendix IX.
