(a) The following requirements are minimum requirements for all classes of waste and are intended to facilitate handling at the disposal site and provide protection of health and safety of personnel at the disposal site.

1. (1) Waste must not be packaged for disposal in cardboard or fiberboard boxes.
2. (2) Liquid waste must be solidified or stabilized by other methods. Only those methods approved by the department in the permit may be used. Liquid waste packaged in absorbent materials is not acceptable for disposal.
3. (3) Free-standing and noncorrosive liquids in solid waste and solidified or stabilized liquid waste must be minimized to the extent reasonably achievable, but in no case must the amount of liquid exceed one-half percent (0.5 percent) of the waste volume.
4. (4) Waste must not be readily capable of detonation or of explosive decomposition or reaction at normal pressures and temperatures, or of explosive reaction with water.
5. (5) Waste must not contain, or be capable of generating, quantities of toxic gases, vapors or fumes harmful to persons transporting, handling or disposing of the waste. This does not apply to low-level radioactive gaseous waste packaged in accordance with paragraph (7) of this subdivision.
6. (6) Waste must not be pyrophoric. Pyrophoric materials contained in waste must be treated, prepared and packaged to be nonflammable.
7. (7) Waste in a gaseous form must be packaged at a pressure that does not exceed 1.5 atmospheres at 68°F (20°C). Total activity must not exceed 100 curies per container.
8. (8) Waste containing hazardous, biological, pathogenic or infectious material must be treated to minimize the potential hazard from the nonradiological materials.

(b) The requirements in this section are intended to provide stability of the waste. Stability is intended to ensure that the waste does not structurally degrade and affect overall stability of the site through slumping, collapse, or other failure of the disposal unit and thereby lead to water infiltration. Stability is also a factor in limiting exposure to an inadvertent intruder, since it provides a recognizable and nondispersible waste.

1. (1) Waste must have structural stability. A structurally stable waste form will generally maintain its physical dimensions and its form, under the expected disposal conditions, such as weight of overburden and compaction equipment, the presence of moisture, and microbial activity, and internal factors such as radiation effects and chemical changes. Structural stability can be provided by the waste form itself, processing the waste to a stable form, or placing the waste in a disposal container or structure that provides stability after disposal.
2. (2) Void spaces within the waste and between the waste and its container must be minimized.
