H.R. 3106Weatherizing Infrastructure in the North and Terrorism Emergency Readiness Act of 2025

What the bill would do

This bill requires the Department of Homeland Security (DHS) to develop and conduct an exercise to enhance collective domestic preparedness for and response to a terrorist attack during an extreme cold weather event (e.g., an event caused by a polar vortex when Arctic air expands southward). The scenario in the exercise must involve a terrorist attack causing cascading effects on critical infrastructure (i.e., systems and assets of vital importance to national security, public health, or safety) and must address how public and private entities can coordinate to mitigate such effects and bolster community resilience.
