The Department of Transportation (DOT or the Department) is proposing revisions to the Department’s regulations for its Disadvantaged Business Enterprise (DBE) program (49 CFR part 26). In its final DBE rule the Department reserved publication of a uniform reporting form and a uniform certification application form for a later date. This document proposes those forms. In addition, this document proposes implementation procedures for a Memorandum of Understanding (MOU) between DOT and the U.S. Small Business Administration (SBA). The MOU streamlines certification procedures for participation in SBA’s 8(a) Business Development (8(a) BD) and Small Disadvantaged Business (SDB) programs, and DOT’s DBE program for small and disadvantaged businesses. Finally, this document proposes substantive changes to several provisions, including: Personal net worth, retainage, the size standard, proof of ethnicity, confidentiality, proof of economic disadvantage, and DBE credit for trucking firms.
