Columbia Generating Station response: We distinguish exempt and non -exempt in our Source Tracking System and, for exempt sources, by adding an "E" after the source tracking number (e.g., 14-001E) included in our source labels.
The distinction is made on the basis of 10CFR30.70 and 30.71. We also distinguish the type of labeling required (i.e., 10 CFR 20.1904-required information vs RAM sticker) on source containers based on 10CFR20 Appendix C quantities or Appendix B, Table 3 concentrations We inventory our non-exempt sources semi-annually, and include the exempt sources every two years.

Does your site make a distinction procedurally or physically, (such as a different marking), between exempt and non-exempt radioactive sources? 2. If so, what limit do you use as the basis for identifying a source as non-exempt? (i.e., 10 CFR 30.70/71, 10 CFR 20 Appendix C, etc.) 3. If so, what is the distinction used (marking, location, procedural controls, etc.)? Respectfully, Craig D.
