Ill. Admin. Code tit. 35, § 726.325
Low-level mixed waste (LLMW), as defined in Section 726.310, is eligible for a storage and treatment conditional exemption if it is generated and managed by a person under a single federal NRC or IEMA license. (Mixed waste generated at a facility with a different license number and shipped to a different person's facility for storage or treatment requires a permit, and such mixed waste is ineligible for this exemption. In addition, NARM waste is ineligible for this exemption.)
