Build America, Buy America Act - Waiver Authority

  • Pursuant to Section 70914(c) of the Build America, Buy America Act, EPA may waive Buy America preference where EPA finds that:
    • Applying the domestic content procurement preference would be inconsistent with the public interest (a "public interest waiver");
    • Types of iron, steel, manufactured products, or construction materials are not produced in the United States in sufficient and reasonably available quantities or of a satisfactory quality (a "nonavailability waiver"); or
    • Inclusion of iron, steel, manufactured products, or construction materials produced in the United States will increase the cost of the overall project by more than 25 percent (an "unreasonable cost waiver").

Waiver review process

  • Waiver requests should follow guidance from the relevant program.
  • General Applicability waivers will be open for at least a 15-day public comment period.
  • Waivers that are specific to a project or a product will be open for a 15-day public comment period.
  • Once the public comment period has closed, EPA will make a determination whether to approve the waiver.
  • Waivers are reviewed by MIAO before EPA approves, signs, and posts the waiver to the "Approved Waivers" website.

There are no waiver proposals currently open for public comment.
