Continuity Guidance Circular 1 (CGC 1): Continuity Guidance for Non-Federal Entities (States, Territories, Tribal, and Local Government Jurisdictions and Private Sector Organizations) [open pdf - 918KB]
"This guidance document provides direction to non-federal entities for developing continuity plans and programs. Continuity planning facilitates the performance of essential functions during all-hazards emergencies or other situations that may disrupt normal operations. By continuing the performance of essential functions through a catastrophic emergency, the State, local, territorial, and tribal governments (non-Federal Governments entities or NFGs) support the ability of the Federal Government to perform National Essential Functions (NEFs), continue Enduring Constitutional Government, and ensure that essential services are provided to the Nation's citizens. A comprehensive and integrated continuity capability will enhance the credibility of our national security posture and enable a more rapid and effective response to, and recovery from, a national emergency."
