Federal Permitting Modernization Act of 2023

This bill streamlines federal permitting for infrastructure projects by modifying environmental review processes under the National Environmental Policy Act (NEPA). It requires agencies to publish a "notice of intent" within 5 business days of starting a project, creates a 60-day public scoping period for environmental reviews, and allows project sponsors to draft environmental impact statements under agency supervision (with agency approval). Courts are restricted from issuing preliminary injunctions to block projects unless the environmental review seriously failed NEPA requirements and couldn't be fixed with additional measures. The bill directly affects federal agencies (like the EPA or Corps of Engineers), infrastructure developers, and the public by accelerating project timelines while maintaining environmental review standards.
