The Department of Energy (DOE) issued a proposed rule under 16 U.S.C. § 824p(h) to expedite the federal authorization of transmission projects. We commented in support of the proposal, including DOE's proposed requirement that project proponents describe how the transmission project would affect power-system greenhouse gas (GHG) emissions. We recommended that DOE clarify that project proponents must also estimate changes to non-power-system GHG emissions (e.g., upstream emissions of natural gas) and power-system emissions of local air pollutants. We also suggested that DOE provide additional guidance on the meaning of terms like "disadvantaged communities" and "communities with environmental justice concerns." Finally, we argued that DOE should provide an opportunity for public comment at the pre-application stage of the process.
