The due diligence program is to check applicants against the named lists
What the document says“examine any relationship of a small business concern seeking an award to any entity or individual included on the lists described in subsections (g)(16)(D) and (o)(20)(D).”
Subsection (a)(3)(C) adds a new subparagraph (C) to subsection (vv)(2). It ties the due diligence program to the eight lists this section put into subsections (g) and (o), by calling for an examination of any relationship between an applicant firm and any entity or individual on those lists.
What the document actually says“examine any relationship of a small business concern seeking an award to any entity or individual included on the lists described in subsections (g)(16)(D) and (o)(20)(D).”
The check must look for any link to a listed group or person. The lists are the ones named earlier in this part.
The same eight lists are used twice. They are a ground to say no. They are also part of the check itself.
