FEMA aid to Texas

I saw this reported a few days ago that FEMA has no more money for Texas.  I was wondering what disaster had befallen Texas?  Further reading said it was the fertilizer plant explosion.  I have no idea why this should qualify.  This is a State of Texas/ corporation issue.  Poor zoning by the State and village and not following the rules by a corporation caused this disaster.  Tell me why someone who lives in Wisconsin should be paying for this?  If the people have a problem they should sue the company and the state.
