This legislation aims to update and enhance the Federal Water Pollution Control Act by streamlining the process for obtaining water quality certifications necessary for projects impacting water bodies. The primary goal is to create a more predictable and efficient system for both state and federal agencies handling certification requests, thereby reducing uncertainty and delays for applicants. Key provisions include a requirement for agencies to publish clear certification requirements within 30 days of the law's enactment and to respond to certification requests within 90 days.
