This page documents the rulemaking process through which the U.S. Department of Energy (DOE), in 2011, revised its regulations regarding implementation of the National Environmental Policy Act (NEPA). A separate web page documents a more complete history of DOE's NEPA regulations.

In 2011, DOE established 20 new categorical exclusions, most of which include criteria (e.g., acreage, location, and height limitations) that limit the covered actions. These categorical exclusions address actions such as stormwater runoff control, alternative fuel vehicle fueling stations and electric vehicle charging stations, and small-scale renewable energy projects. DOE also revised many previously established categorical exclusions and made other changes.
