Categorical Exclusions 2022
​​A Categorical Exclusion (CX) is a determination that a specific proposed action is consistent with a previously identified category of actions that normally do not have significant environmental impacts and therefore normally do not require preparation of an Environmental Impact Statement (EIS). Individual proposed actions must satisfy several conditions to qualify. At Bonneville Power Administration (BPA), the National Environmental Policy Act (NEPA) Compliance Officer approves application of CXs. The normal CX review process is 3 months depending on interagency consultation requirements.
