It's the Tenth Amendment:
The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.
It's people that claim a federal power, like "emergency management" that need to demonstrate in the Constitution where they are authorized that power. Since "emergency management" is not a power authorized by Congress in Article 1 Section 8, emergency management is relegated to the states.
