Build America, Buy America: Office of Transportation and Air Quality

The Build America, Buy America Act strengthens Made in America Laws and will bolster America’s industrial base, protect national security, and support high-paying jobs.

BABA requires that on or after May 14, 2022, the head of each covered federal agency shall ensure that “none of the funds made available for a federal financial assistance program for infrastructure… may be obligated for a project unless all of the iron, steel, manufactured products, and construction materials used in the project are produced in the United States,” (Section 70914(a)). The EPA is a covered agency.
