(d) Applicability of ch. NR 665 standards. Owners and operators of boilers and industrial furnaces that burn hazardous waste and are operating under an interim license are subject to all of the following provisions of ch.
NR 665, except as provided otherwise by this section:
NR 666.103(1)(e)
(e) Special requirements for furnaces. The following controls apply during an interim license to industrial furnaces (e.g., kilns, cupolas) that feed hazardous waste for a purpose other than solely as an ingredient (see subd.
2.) at any location other than the hot end where products are normally discharged or where fuels are normally fired:
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:
