45 C.F.R. § 630.670
Suspension means an action taken by a Federal agency that immediately prohibits a recipient from participating in Federal Government procurement contracts and covered nonprocurement transactions for a temporary period, pending completion of an investigation and any judicial or administrative proceedings that may ensue. A recipient so prohibited is suspended, in accordance with the Federal Acquisition Regulation for procurement contracts (48 CFR part 9, subpart 9.4) and the common rule, Government-wide Debarment and Suspension (Nonprocurement), that implements Executive Order 12549 and Executive Order 12689. Suspension of a recipient is a distinct and separate action from suspension of an award or suspension of payments under an award.
