10 C.F.R. § 1706.6
(a) Advisory or assistance services. There shall be included in all formal Board solicitations for advisory or assistance services where the contract amount is expected to exceed $25,000 (or the then applicable small purchases threshold), a provision requiring a certificate representing whether award of the contract to the offeror would present actual or potential OCIs. Apparent successful offerors will be required to submit such certificates, but the Board may also require such a certificate to be submitted in other circumstances, such as:
(2) In the case of modifications for additional effort under Board contracts, except those issued under the “changes” clause. If a certificate has been previously submitted with regard to the contract being modified, only an updating of such statement shall be required for a contract modification.
In addition, if determined appropriate by the contracting officer for the Board, such certificates may be required in connection with any other contracts subject to this part or in which this part has been incorporated by reference.
