Currently, infrastructure projects in the U.S. can take years or even decades to get off the ground because the permitting process is slow and permits can be cancelled after a new administration takes office. This creates 'regulatory uncertainty,' which can discourage companies from investing in expensive clean energy or transportation projects. If this bill becomes law, it would be much harder for the government to pull the plug on a project once it starts, and it forces agencies to work on a faster schedule. However, critics worry this might limit the government's ability to stop a project if new environmental risks are discovered later.
