State Guidelines for Greenhouse Gas Emissions from Existing Electric Utility Generating Units

An advance notice of proposed rulemaking (ANPRM) is a notice intended to solicit information from the public as the Environmental Protection Agency (EPA) considers proposing a future rule. In this ANPRM, the EPA is considering proposing emission guidelines to limit greenhouse gas (GHG) emissions from existing electric utility generating units (EGUs) and is soliciting information on the proper respective roles of the state and federal governments in that process, as well as information on systems of emission reduction that are applicable at or to an existing EGU, information on compliance measures, and information on state planning requirements under the Clean Air Act (CAA). This ANPRM does not propose any regulatory requirements.
