5 CFR § 919.430
How do I check to see if a person is excluded or disqualified?
November 4, 2020
You check to see if a person is excluded or disqualified in two ways:
(a) You as an agency official must check the EPLS when you take any action listed in §919.425.
(b) You must review information that a participant gives you, as required by §919.335, about its status or the status of the principals of a transaction.
