Categorical Exclusion

Operational Activities

Exclusion Text

B1 Research, development, testing, and evaluation activities, or laboratory operations conducted within existing enclosed facilities consistent with previously established safety levels and in compliance with applicable Federal, Tribal, State, and local requirements to protect the environment when it will result in no, or de minimus change in the use of the facility. If the operation will substantially increase the extent of potential environmental impacts or is controversial, an EA (and possibly an EIS) is required.

Disclaimer

This CE Explorer tool is not an authoritative source and creates no rights or obligations. When using the CE Explorer Tool, Federal agencies and stakeholders should review the relevant agency's NEPA procedures for information about how to apply the CE, including any limitations or potential extraordinary circumstances, and to ensure that a CE is current and applicable to a given proposed action. For ease of use, a link to each agency's NEPA procedures and CEs is provided along with the text of the CE. To adopt and use another agency's categorical exclusion, an agency must follow the steps described in section 109 of NEPA, 42 U.S.C. 4336c.
