60 Minutes+ reports that government documents back up allegations that SpaceX’s Starbase test facility in Texas has violated its federal permit through excessive road closings and has encroached and trespassed on the protected Boca Chica National Wildlife Refuge.

The documents back up a claim by the environmental group Save Rio Grande Valley (Save RGV) that SpaceX has been closing the Texas state highway that runs through its operation for more than the 300 hours per year allowed under the permit from the Federal Aviation Administration (FAA). The organization sent a letter to the local district attorney outlining its concerns.

Vice reports that SpaceX gave a Friday deadline for two Boca Chica Village homeowners to sell their homes or Elon Musk’s launch provider would pursue “alternate approaches” to get them to vacate the settlement near the company’s south Texas spaceport.

A dispute has erupted between several environmental groups and the federal government over the impact of SpaceX’s test operations at Boca Chica Beach in south Texas.

The issue: the Federal Aviation Administration (FAA) approved SpaceX’s plan to use the coastal site for launching its Falcon 9 and Falcon Heavy rockets up to 12 times per year.

However, Elon Musk’s company has instead been using its facilities to develop and flight test its larger Starship and Super Heavy boosters. The resulting impacts have been much greater than anticipated under the original proposal, environmental groups argue.
