It suggests the FAA’s role is consideration of launch failure and safety on the proposed plant. FERC also evaluated the proposal. FERC doesn’t really do environmental reviews.

Here is a document from April which at the time said EPA had no comment on the draft environmental impact statement as part of an interagency process: https://www.energy.gov/sites/default/files/2021-03/SAR%20-%2...

In short, it looks as if all the usual players are engaged here. While I suspect the FAA has considered the impact of Oil and gas infrastructure on flight paths and airports, I would guess their involvement in this kind of process is an extra layer, not a circumvention.
