(a) Limited CUI marking waivers within the agency. When an agency designates information as CUI but determines that marking it as CUI is excessively burdensome, an agency's CUI SAO may approve waivers of all or some of the CUI marking requirements while that CUI remains within agency control.

(b) Limited legacy material marking waivers within the agency.

(1) In situations in which the agency has a substantial amount of stored information with legacy markings, and removing legacy markings and designating or re-marking it as CUI would be excessively burdensome, the agency's CUI SAO may approve a waiver of these requirements for some or all of that information while it remains under agency control.

(2) When an authorized holder re-uses any legacy information or information derived from legacy documents that qualifies as CUI, they must remove or redact legacy markings and designate or re-mark the information as CUI, even if the information is under a legacy material marking waiver prior to re-use.

(c) Exigent circumstances waivers.

(1) In exigent circumstances, the agency head or the CUI SAO may waive the provisions and requirements established in this part or the CUI Registry for any CUI while it is within the agency's possession or control, unless specifically prohibited by applicable laws, regulations, or Government-wide policies.

(2) Exigent circumstances waivers may apply when an agency shares the information with other agencies or non-Federal entities. In such cases, the authorized holders must make recipients aware of the CUI status of any disseminated information.

(d) For all waivers.

(1) The CUI SAO must still ensure that the agency appropriately safeguards and disseminates the CUI. See §2002.20(a)(7);

(2) The CUI SAO must detail in each waiver the alternate protection methods the agency will employ to ensure protection of CUI subject to the waiver;

(3) All marking waivers apply to CUI subject to the waiver only while that agency continues to possess that CUI. No marking waiver may accompany CUI when an authorized holder disseminates it outside that agency;

(4) Authorized holders must uniformly and conspicuously apply CUI markings to all CUI prior to disseminating it outside the agency unless otherwise specifically permitted by the CUI EA; and

(5) When the circumstances requiring the waiver end, the CUI SAO must reinstitute the requirements for all CUI subject to the waiver without delay.

(e) The CUI SAO must:

(1) Retain a record of each waiver;

(2) Include a description of all current waivers and waivers issued during the preceding year in the annual report to the CUI EA, along with the rationale for each waiver and the alternate steps the agency takes to ensure sufficient protection of CUI; and

(3) Notify authorized recipients and the public of these waivers.
