All funds made available through the Middle Mile Grant Program for broadband infrastructure must comply with the Build America, Buy America Act (Act) Pub. L. No. 117-58, §§ 70901-52.

This Act requires that all of the iron, steel, manufactured products, and construction materials used in the project are produced in the United States unless a waiver is requested and granted.

Under the Build America, Buy America Act, the Secretary of Commerce (Secretary) may waive the application of this preference when:

Applying the domestic content procurement preference would be inconsistent with the public interest;

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;

The 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.
