Section 236.522 - Stability requirements for waste form(a) The requirements of this section and §§ 236.523 and 236.524 (relating to stabilization of liquid waste; and minimization of void spaces within waste packages) are minimum requirements that are intended to provide stability of the waste. Stability is intended to ensure that the waste does not degrade and affect overall stability of the site through slumping, collapse or other failure of the disposal unit. Stability is also a factor in limiting exposure to an inadvertent intruder, since it provides a recognizable and nondispersible waste.(b) 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. This section cited in 25 Pa. Code § 236.502 (relating to classes of waste).
