Unfortunately there's a warranted general skepticism for any US federal agency, due to the people at the top. The current cabinet secretary was a former oil lobbyist, and seems to have put significant restrictions the scope of environmental impact research via order (https://www.eenews.net/stories/1060059865).

It's hard to get a sense of perspective, because everything is so politicized. But it is what it is, and I think questioning and skepticism is healthy, given the environment.
