NR 666.220NR 666.220 What does a storage and treatment conditional exemption do? The storage and treatment conditional exemption exempts your low-level mixed waste from the regulatory definition of hazardous waste in s. NR 661.0003 if your waste meets the eligibility criteria in s. NR 666.225 and you meet the conditions in s. NR 666.230. NR 666.225NR 666.225 What wastes are eligible for the storage and treatment conditional exemption? Low-level mixed waste (LLMW), defined in s. NR 666.210, is eligible for this conditional exemption if it is generated and managed by you under a single NRC or NRC agreement state license. (Mixed waste generated at a facility with a different license number and shipped to your facility for storage or treatment requires a hazardous waste operating license and is ineligible for this exemption. In addition, NARM waste is ineligible for this exemption.) NR 666.225 HistoryHistory: CR 05-032: cr. Register July 2006 No. 607, eff. 8-1-06.

The dated notification shall include your name, address, EPA hazardous waste identification number, NRC or NRC agreement state license number, the hazardous waste codes and storage units for which you are seeking an exemption and a statement that you meet the conditions of this subchapter. Your notification shall be signed by your authorized representative who certifies that the information in the notification is true, accurate and complete. You shall notify us of your claim either within 90 days of August 1, 2006, or within 90 days of when a storage unit is first used to store conditionally exempt LLMW.

NR 666.240(1)(1) Your LLMW will automatically lose the storage and treatment conditional exemption if you fail to meet any of the conditions specified in s. NR 666.230. When your LLMW loses the exemption, you shall immediately manage that waste which failed the condition as hazardous waste under chs. NR 660 to 670, and the storage unit storing the LLMW immediately becomes subject to hazardous waste container or tank storage requirements under subch. I of ch. NR 664 or subch. J of ch. NR 664.

NR 666.230. In reviewing a reclaimed conditional exemption under this section, we may add conditions to the exemption to ensure that waste management during storage and treatment of the LLMW will protect human health and the environment.

NR 666.255NR 666.255 When is your LLMW no longer eligible for the storage and treatment conditional exemption? NR 666.255(1)(1) When your LLMW has met the requirements of your NRC or NRC agreement state license for decay-in-storage and can be disposed of as non-radioactive waste, then the conditional exemption for storage no longer applies. On that date your waste is subject to hazardous waste regulation under the relevant sections of chs. NR 660 to 670, and the time period for accumulation of a hazardous waste as specified in s. NR 662.016 or 662.017 begins. NR 666.255(2)(2) When your conditionally exempt LLMW, which has been generated and stored under a single NRC or NRC agreement state license number, is removed from storage, it is no longer eligible for the storage and treatment exemption. However, your waste may be eligible for the transportation and disposal conditional exemption at s. NR 666.305. NR 666.255 HistoryHistory: CR 05-032: cr.

NR 666.260NR 666.260 Do closure requirements apply to units that stored LLMW prior to the effective date of this subchapter? Interim licensed and operating licensed hazardous waste storage units that have been used to store only LLMW prior to August 1, 2006 and, after that date, store only LLMW which becomes exempt under this subchapter, are not subject to the closure requirements of chs. NR 664 and 665. Storage units (or portions of units) that have been used to store both LLMW and non-mixed hazardous waste prior to August 1, 2006 or are used to store both after that date remain subject to closure requirements with respect to the non-mixed hazardous waste.
