Treatment standards for hazardous debris

1. Treatment standards. Hazardous debris must be treated prior to land disposal as follows unless the department determines under subdivision b of subsection 5 of section 33.1-24-02-03 that the debris is no longer contaminated with hazardous waste or the debris is treated to the waste-specific treatment standard provided in sections 33.1-24-05-280 through 33.1-24-05-289 for the waste contaminating the debris. a. General. Hazardous debris must be treated for each "contaminant subject to treatment" defined by subsection 2 using the technology or technologies identified in table 1 of this section. b. Characteristic debris. Hazardous debris that exhibits the characteristic of ignitability, corrosivity, or reactivity identified under sections 33.1-24-02-11, 33.1-24-02-12, and 33.1-24-02-13, respectively, must be deactivated by treatment using one of the technologies identified in table 1 of this section. c. Mixtures of debris types. The treatment standards of table 1 in this section must be achieved for each type of debris contained in a mixture of debris types. If an immobilization technology is used in a treatment train, it must be the last treatment technology used. d. Mixtures of contaminant types. Debris that is contaminated with two or more contaminants subject to treatment identified under subsection 2 must be treated for each contaminant using one or more treatment technologies identified in table 1 of this section. If an immobilization technology is used in a treatment train, it must be the last treatment technology used. e. Waste polychlorinated biphenyls. Hazardous debris that is also a waste polychlorinated biphenyl under 40 CFR part 761 is subject to the requirements of either 40 CFR part 761 or the requirements of this section, whichever are more stringent. 2. Contaminants subject to treatment. Hazardous debris must be treated for each "contaminant subject to treatment". The contaminants subject to treatment must be determined as follows: a. Toxicity characteristic debris. The contaminants subject to treatment for debris that exhibits the toxicity characteristic by section 33.1-24-02-14 are those extraction procedure constituents (hazardous waste numbers D004 through D017) for which the debris exhibits the toxicity characteristic. b. Debris contaminated with listed waste. The contaminants subject to treatment for debris that is contaminated with a prohibited listed hazardous waste are those constituents or wastes for which treatment standards are established for waste under section 33.1-24-05-280. c. Cyanide reactive debris. Hazardous debris that is reactive because of cyanide must be treated for cyanide. 3. Conditioned exclusion of treated debris. Hazardous debris that has been treated using one of the specified extraction or destruction technologies in table 1 of this section and that does not exhibit a characteristic of hazardous waste identified under sections 33.1-24-02-10 through 33.1-24-02-14 after treatment is not a hazardous waste and need not be managed in a hazardous waste facility. Hazardous debris contaminated with a listed waste that is treated by an immobilization technology specified in table 1 is a hazardous waste and must be managed in a hazardous waste facility. 4. Treatment residuals. a. General requirements. Except as provided by subdivisions b and d: (1) Residue from the treatment of hazardous debris must be separated from the treated debris using simple physical or mechanical means; and (2) Residue from the treatment of hazardous debris is subject to the waste-specific treatment standards provided by sections 33.1-24-05-280 through 33.1-24-05-289 for the waste contaminating the debris. b. Nontoxic debris. Residue from the deactivation of ignitable, corrosive, or reactive characteristic hazardous debris (other than cyanide-reactive) that is not contaminated with a contaminant subject to treatment defined by subsection 2, must be deactivated prior to land disposal and is not subject to the waste-specific treatment standards of sections 33.1-24-05-280 through 33.1-24-05-289. c. Cyanide-reactive debris. Residue from the treatment of debris that is reactive because of cyanide must meet the treatment standards for D003 in "treatment standards for hazardous wastes" at section 33.1-24-05-280. d. Ignitable nonwastewater residue. Ignitable nonwastewater residue containing equal to or greater than ten percent total organic carbon is subject to the technology specified in the treatment standard for D001: ignitable liquids. e. Residue from spalling. Layers of debris removed by spalling are hazardous debris that remain subject to the treatment standards of this section. Table 1.

Debris contaminated with a dioxin-listed waste.6 Obtain an "Equivalent Technology" approval under subsection 2 of section 33.1-24-05-282,8 except that this requirement does not apply to vitrification. C. Immobilization Technologies: 1. Macroencapsulation: Application of surface coating materials, such as polymeric organics (for example, resins and plastics) or use of a jacket of inert inorganic materials to substantially reduce surface exposure to potential leaching media. Encapsulating material must completely encapsulate debris and be resistant to degradation by the debris and its contaminants and materials into which it may come into contact after placement (leachate, other waste, microbes). None. 2. Microencapsulation: Stabilization of the debris with the following reagents (or waste reagents) such that the leachability of the hazardous contaminants is reduced: (1) Portland cement; or (2) lime/pozzolans (for example, fly ash and cement kiln dust). Reagents (for example, iron salts, silicates, and clays) may be added to enhance the set/cure time and/or compressive strength, or to reduce the leachability of the hazardous constituents.5 Leachability of the hazardous contaminants must be reduced. None. 3. Sealing: Application of an appropriate material which adheres tightly to the debris surface to avoid exposure of the surface to potential leaching media. When necessary to effectively seal the surface, sealing entails pretreatment of the debris surface to remove foreign matter and to clean and roughen the surface. Sealing materials include epoxy, silicone, and urethane compounds, but paint may not be used as a sealant. Sealing must avoid exposure of the debris surface to potential leaching media and sealant must be resistant to degradation by the debris and its contaminants and materials into which it may come into contact after placement (leachate, other waste, microbes). None. FOOTNOTE: 1Hazardous debris must be treated by either these standards of the waste-specific treatment standards for the waste contaminating the debris. The treatment standards must be met for each type of debris contained in a mixture of debris types, unless the debris is converted into treatment residue as a result of the treatment process. Debris treatment residuals are subject to the waste-specific treatment standards for the waste contaminating the debris. FOOTNOTE: 2Contaminant restriction means that the technology is not best demonstrated available technologies for that contaminant. If debris containing a restricted contaminant is treated by the technology, the contaminant must be subsequently treated by a technology for which it is not restricted in order to be land disposed (and excluded from article 33.1-24). FOOTNOTE: 3"Clean debris surface" means the surface, when viewed without magnification, shall be free of all visible contaminated soil and hazardous waste except that residual staining from soil and waste consisting of light shadows, slight streaks, or minor discolorations, and soil and waste in cracks, crevices, and pits may be present provided that such staining and waste and soil in cracks, crevices, and pits shall be limited to no more than 5% of each square inch of surface area. FOOTNOTE: 4Acids, solvents, and chemical reagents may react with some debris and contaminants to form hazardous compounds. For example, acid washing of cyanide-contaminated debris could result in the formation of hydrogen cyanide. Some acids may also react violently with some debris and contaminants, depending on the concentration of the acid and the type of debris and contaminants. Debris treaters should refer to the safety precautions specified in Material Safety Data Sheets for various acids to avoid applying an incompatible acid to a particular debris/contaminant combination. For example, concentrated sulfuric acid may react violently with certain organic compounds, such as acrylonitrile. FOOTNOTE: 5If reducing the particle size of debris to meet the treatment standards results in material that no longer meets the 60 mm minimum particle size limit for debris, such material is subject to the waste-specific treatment standards for the waste contaminating the material, unless the debris has been cleaned and separated from contaminated soil and waste prior to size reduction. At a minimum, simple physical or mechanical means must be used to provide such cleaning and separation of nondebris materials to ensure that the debris surface is free of caked soil, waste, or other nondebris material. FOOTNOTE: 6Dioxin-listed wastes are hazardous waste numbers F020, F021, F022, F023, F026, and F027. FOOTNOTE: 7Thermal desorption is distinguished from thermal destruction in that the primary purpose of thermal desorption is to volatilize contaminants and to remove them from the treatment chamber for subsequent destruction or other treatment. FOOTNOTE: 8The demonstration "Equivalent Technology" under subsection 2 of section 33.1-24-05-282 must document that the technology treats contaminants subject to treatment to a level equivalent to that required by the performance and design and operating standards for other technologies in this table such that residual levels of hazardous contaminants will not pose a hazard to human health and the environment absent management controls. FOOTNOTE: 9Any soil, waste, and other nondebris material that remains on the debris surface (or remains mixed with the debris) after treatment is considered a treatment residual that must be separated from the debris using, at a minimum, simple physical or mechanical means. Examples of simple physical or mechanical means are vibratory or trommel screening or water washing. The debris surface need not be cleaned to a "clean debris surface" as defined in footnote 3 when separating treated debris from residue; rather, the surface must be free of caked soil, waste, or other nondebris material. Treatment residuals are subject to the waste-specific treatment standards for the waste contaminating the debris.
