(a) EPA OSDBU may initiate a certification determination whenever it receives credible information calling into question an entity's eligibility as an MBE or WBE. Upon its completion of a certification determination, EPA OSDBU will issue a written determination regarding the MBE or WBE status of the questioned entity.

(b) If EPA OSDBU finds that the entity does not qualify as an MBE or WBE, EPA OSDBU will decertify the entity as an MBE or WBE, and immediately remove the entity from the EPA OSDBU list of certified MBEs and WBEs.

(c) If EPA OSDBU finds that the entity continues to qualify as an MBE or WBE, the determination remains in effect for three years from the date of the decision under the same conditions as if the entity had been granted MBE or WBE certification under § 33.205.
