I hear Crawford, Texas is a great place for hog farms.

how about a nukyaler waste dump?
 

I live 2 miles from a giant enclosed egg farm.  Periodically when the nearby fields are fallow they spread the chicken manure on the field with big spreaders.  I'm glad I don't live closer as the ammonia and H2S can be noticed at my range.

Without this exemption they would have to do what?
Notify the government when they spread manure?
Install ammonia and H2S detectors downwind?

P.S.  I think sometimes they incinerate the dead birds as I get the distinct smell of burning feathers.

By contrast the horse manure I spread smells pretty nice, organic-like.

Equals biohazard.  All this manure ought to be biodigested, turned into clean biogas/fuel cell cogeneration energy, and organic fertilizer that prevents massive GHG effects.

Bird flu evoloved in raw manure contamination conditions.  Insects carry bacteria and viruses between human and animal hosts and manure pit, this madness will end one way or another.  With massive disease outbreak or voluntary redesign of the food production waste stream.

Corporate farming lobbyists and their pet politicians are aiming us in the direction of contagion.
