The U.S. Environmental Protection Agency (EPA) has issued a regulatory interpretation clarifying that power generation facilities not connected to the public electricity grid, termed 'islanded' facilities, are not subject to the Clean Air Act's (CAA) acid rain provisions. This guidance, detailed in a memo from EPA Assistant Administrator for Air and Radiation Aaron Szabo, aims to remove regulatory hurdles for data center and AI infrastructure development.
