Requires the System to operate consistent with the National Oceanic and Atmospheric Administration's (NOAA) All-Hazards Radio System.

Requires the Office to establish a process for issuing credentials to enable officials responsible for issuing safety warnings to access the System.

Directs the Federal Communications Commission (FCC) to initiate proceedings to: (1) allow licensees providing commercial mobile service to elect to transmit System alerts to subscribers; and (2) require public broadcast television licensees to install necessary equipment to enable transmitters to receive and retransmit System alerts.

Requires the Director of the Office to establish a National Alert System Working Group to develop recommendations for protocols, procedures, guidelines, and standards and to coordinate with the operators of nuclear power plants and other critical infrastructure facilities to integrate emergency alert systems.
