2.  Regulated under the Atomic Energy Act ◦ Low concentrations of source, byproduct and special nuclear material ◦ Accelerator produced material ◦ Generally exempted materials, products & devices (e.g. smoke detectors, luminous dials, etc.)  Not Regulated under the Atomic Energy Act ◦ Naturally occurring radioactive material (NORM) except radium & certain other discrete sources ◦ Technologically-enhanced NORM (TENORM) ◦ Pre-UMTRCA uranium and thorium ore processing waste (FUSRAP)

3. Waste Specific:  NRC Decommissioning Plan approval  NRC General Exemption  NRC/Agreement State license condition/amendment  NRC/Agreement State approval letter  NRC/Agreement State specific exemption* Disposal Facility-Specific:  State law or regulation  RCRA permit condition/amendment *Policy Note: A 10 CFR 20.2002 alternate disposal authorization is not an exemption. However, NRC policy is to issue an exemption concurrently.

4.  Select RCRA Subtitle-C Sites are viable options for LARW  Characteristics similar to Part 61 LLRW sites (‘hybrid’ sites) ◦ Remote location with limited population ◦ Meet performance assessment criteria ◦ Desert environment with low annual rainfall ◦ Deep depth to groundwater Not all RCRA sites meet these criteria
