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)1.1. Hazardous waste may be burned solely as an ingredient.
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.b.b. The boiler or industrial furnace met the interim license eligibility requirements under s. NR 670.070 for subch. O or 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)(2)Certification of precompliance.
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)1.1. General facility information:
NR 666.103(2)(b)1.a.a. EPA facility ID number.
