The Federal Aviation Administration is studying a proposal for a private spaceport on the Georgia coast. The Camden County Spaceport would be a facility where companies like SpaceX could launch rockets.

One of the first steps in the permitting process is an environmental review. The deadline for the public to submit questions about the impact of the project is Jan. 18.

At this point, coastal environmental groups aren’t flat out against the idea. Satilla Riverkeeper Ashby Nix Worley Said she mostly has a lot of questions at this point.

“That’s kind of where we’re at,” she said. “We have a lot of concerns. This is a large project that could really have not only a large local impact but a regional impact.”

Some of the big questions are, what would this mean for the rivers and for Cumberland Island, and what happens if there’s an accident.

“We want to make sure we’ve looked at any and all issues that are addressed. So all of that’s important,” said Steve Howard, the Camden County administrator and project lead on the spaceport proposal. “Safety is paramount on a project of this magnitude. If we can’t prove that, the project doesn’t go forward.”

The FAA is collecting comments on its website. The agency will use them to inform its environmental study.
