48 C.F.R. § 604.7002 – Procedures.

(a) Overseas contracting activities.
1. (1) A/OPE reviews all procurements that exceed the warrant levels of post contracting officers. Post contracting officers may request A/OPE review and assistance for transactions below this level.
2. (2) Personal services agreements. Prior A/OPE approval is not applicable to personal services agreements, as they are not subject to procurement statute and regulation.
(b) Domestic contracting activities and Regional Procurement Support Offices. A/OPE reviews domestic acquisitions as described in the A/LM/AQM Quality Assurance Plan.
(c) Delegation or waiver. The Procurement Executive may delegate or waive the review requirements. In such instances, the Procurement Executive shall provide to each head of the contracting activity, as appropriate, a written delegation or waiver of these requirements.
