According to the national environmental policy act (nepa), actions that have little or no potential for significant environmental impact are classified into the category of

Categorical Exclusion.

Explanation:

A categorical exclusion its any action that has do not have a significant impact on the environment, therefore it does not require an environmental assessment, nor any additional paperwork, thus, saving time and resources.

However, this procedure may vary from one Federal Agency to another, as according to NEPA "each Federal agency is required to develop NEPA procedures that supplement the CEQ Regulations".
