Categorical Exclusions 2020
A 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 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.
