When must agencies implement OMB guidance for personal identity verification?

The implementation of Office of Management and Budget (OMB) guidance for personal identity verification is essential for ensuring that individuals accessing federally controlled facilities or information systems are properly verified and authenticated. Agencies are required to follow this guidance specifically when contractors have routine physical access to these sensitive areas or systems. This requirement is rooted in the need to enhance security and protect federal assets from unauthorized access, thereby ensuring the integrity of operations and safeguarding sensitive information.

By focusing on contractors with routine physical access, the guidance places a significant emphasis on security protocols that are necessary to mitigate risks associated with identity theft or unauthorized access. This requirement is crucial for maintaining the overall security posture of federal agencies and upholding regulatory compliance.

The other options suggest different scenarios for implementing OMB guidance, but they do not specifically relate to the fundamental need for secure access as outlined for contractors with routine physical access. These scenarios may not necessarily trigger the same level of security concern and requirement for identity verification as the continuous access to sensitive environments does.
