While FERC and the gas pipeline industry believe that the policy will be tweaked, I see some serious NEPA challenges ahead. The issues seem similar to what FERC's hydropower program faced when the Commission was asked to analyze cumultive impacts in the mid 1980s. Also, the outcome of FERC's review will also spill over to LNG Export Terminals, especially with respect to the need to anlyze greenhouse gas and climate change in FERC environmental reviews.
