Categorical Exclusions (CX) – Categorical exclusions are categories of actions that DOE has determined, by regulation, do not individually or cumulatively have a significant effect on the human environment and for which neither an environmental assessment nor an environmental impact statement is typically required. Title 10 Code of Federal Regulations Part 1021, National Environmental Policy Act Implementing Procedures, Appendices A and B to Subpart D, list DOE's categorical exclusions. Appendix A classes of actions are those actions considered to be general agency actions, such as awarding a contract or hiring personnel. Appendix B classes of actions include actions such as property transfers, erosion control, sampling and characterization of water, soil, rock, or contaminants, or, drilling wells for sampling or monitoring of groundwater. The table below provides a list (with links) of recent CX Appendix B determinations.
