5 C.F.R. § 250.209
If OPM finds that an agency has taken an action contrary to a law, rule, regulation, or standard that OPM administers, OPM may require the agency to take corrective action. OPM may suspend or revoke a delegation agreement established under 5 U.S.C. 1104(a)(2) at any time if it determines that the agency is not adhering to the provisions of the agreement. OPM may suspend or withdraw any authority granted under this chapter to an agency, including any authority granted by delegation agreement, when OPM finds that the agency has not complied with qualification standards OPM has issued, instructions OPM has published, or the regulations in this chapter of the regulation. OPM also may suspend or withdraw these authorities when it determines that doing so is in the interest of the civil service for any other reason.
