5 C.F.R. § 900.402
(a) This subpart applies to each program for which Federal financial assistance is authorized under a law administered by OPM, including the federally assisted programs listed in appendix A to this subpart. It also applies to money paid, property transferred, or other Federal financial assistance extended under a program after the effective date of this subpart pursuant to an application approved before that effective date. This subpart does not apply to:
(4) Employment practices, under a program, of an employer, employment agency, or labor organization, except to the extent described in § 900.404(c).
The fact that a program is not listed in appendix A to this subpart does not mean, if title VI is otherwise applicable, that the program is not covered. Other programs under statutes now in force or hereinafter enacted may be added to appendix A to this subpart.
