(1) Class A waste is waste that is usually segregated from other waste classes at the disposal site. The physical form and characteristics of Class A waste must meet the minimum requirements set forth in section 382.81(a) of this Part. If Class A waste also meets the stability requirements set forth in section 382.81(b) of this Part, it is not necessary to segregate the waste for disposal.

(2) Class B waste is waste that must meet more rigorous requirements on waste form to ensure stability after disposal. The physical form and characteristics of Class B waste must meet both the minimum and stability requirements set forth in section 382.81 of this Part.

(3) Class C waste is waste that not only must meet more rigorous requirements on waste form to ensure stability but also requires additional measures at the land disposal facility to protect against inadvertent intrusion. The physical form and characteristics of Class C waste must meet both the minimum and stability requirements set forth in section 382.81 of this Part.

(4) Waste that is not generally acceptable for disposal at a land disposal facility is waste for which waste form and disposal methods must be different, and in general more stringent, than those specified for Class C waste. In the absence of specific requirements in this Part, proposals for disposal of this waste may be submitted to the department for approval, pursuant to section 382.83 of this Part.

(5) Except for NARM waste contaminated with radium-226 and its decay products, NARM waste will be classified pursuant to section 382.83 of this Part and not pursuant to section 382.80(f). NARM waste contaminated with radium-226 and its decay products will be classified pursuant to subdivisions (c), (e), (g) and (h) of this section.

(1) If the concentration does not exceed 0.1 times the value in Table 1, the waste is Class A.

(2) If the concentration exceeds 0.1 times the value in Table 1, but does not exceed the value in Table 1, the waste is Class C.

(3) If the concentration exceeds the value in Table 1, the waste is not generally acceptable for disposal at a land disposal facility.

(4) For wastes containing mixtures of radionuclides listed in Table 1, the total concentration will be determined by the sum-of-fractions rule described in subdivision (g) of this section.

(1) If the concentration does not exceed the value in column 1 of Table 2, the waste is Class A.

(2) If the concentration exceeds the value in column 1 of Table 2, but does not exceed the value in column 2, the waste is Class B.

(3) If the concentration exceeds the value in column 2 of Table 2, but does not exceed the value in column 3, the waste is Class C.

(4) If the concentration exceeds the value in column 3 of Table 2, the waste is not generally acceptable for disposal at land disposal facilities.

(5) For wastes containing mixtures of the radionuclides listed in Table 2, the total concentration will be determined by the sum-of-fractions rule described in subdivision (g) of this section.

(1) If the concentration of a radionuclide listed in Table 1 does not exceed 0.1 times the value listed in Table 1, the class will be that determined by the concentration of radionuclides listed in Table 2.

(2) If the concentration of a radionuclide listed in Table 1 exceed 0.1 times the value listed in Table 1 but does not exceed the value in Table 1, the waste will be Class C, provided the concentration of radionuclides listed in Table 2 does not exceed the value shown in column 3 of Table 2.

(1) The concentration of a radionuclide may be determined by indirect methods such as use of scaling factors which relate to the inferred concentration of one radionuclide to another that is measured, or radionuclide material accountability, if it is reasonably ensured that the indirect methods can be correlated with actual measurements.

(2) The concentration of a radionuclide may be averaged over the volume of the waste, (or the weight of the waste if the concentration is expressed in units of nanocuries per gram. If the waste form is a homogeneous mixture of waste in a solidification agent or matrix, the solidification agent or matrix may be included in the volume or weight of the waste. The concentration of radionuclides in discrete objects (such as sealed sources, filters, and metal components containing induced radioactivity) that are encapsulated in solidification agent or matrix must be averaged over the volume of the object, not of the solidification agent or matrix. The volume of packaging, containers, liners, or overpacks cannot be included in this calculation, nor can the volume of the waste mixture be artificially increased by the addition of solids or objects even if they are considered as waste, NARM waste, or solid waste.
