The National Sand, Stone and Gravel Association (NSSGA) is the leading voice and advocate for the aggregates industry. We are committed to fulfilling the critical role the aggregates industry will play in providing billions of tons of aggregates the necessary to achieve the IIJA’s goals. The NSSGA submits this comment in response the Department of Transportation (DOT) Request for Information (RFI) Docket No. DOT-OST-2022-0047: Construction Materials Used in Federal Financial Assistance Projects for Transportation Infrastructure in the United States under the Build America, Buy America Act (BABA)(P.L.117-58). The Department of Transportation’s effort to implement the domestic procurement requirements for “construction materials” contained in the BABA must begin with clear, unambiguous communications to State DOTs, construction companies and construction materials providers of what “construction materials” are exempted in the BABA law itself, from BABA’s requirements.
