(A) Waste shall 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. (B) Notwithstanding the provisions in paragraphs (1)(C) and (D) of this subsection, liquid wastes, or wastes containing liquid, shall be converted into a form that contains as little free-standing and non-corrosive liquid as is reasonably achievable, but in no case shall the liquid exceed 1.0% of the volume of the waste when the waste is in a disposal container designed to ensure stability, or 0.5% of the volume of the waste for waste processed to a stable form. (C) Void spaces within the waste and between the waste and its package shall be reduced to the extent practicable. (c) Labeling. Each package of waste shall be clearly labeled to identify whether it is Class A, Class B, or Class
C waste, in accordance with subsection (a) of this appendix.
