Is Brownfield Development Health Risk Tolerance Out of Whack?

The health risk intolerance for brownfield development hovers around one in one million, and is much lower than all other regulatory areas, argues environmental attorney Richard Opper. He provides examples for comparison, including flying on an airplane and being struck by lightening. He continues, 

What kind of life risks are comparable to this level of certainty?  If we consult a source such as the National Oceanic and Atmospheric Administration, we are informed that an equivalent risk is the likelihood of any one of us being struck by lightning in any given year.[ii]  I have to condition that factoid with the note they provide to the effect that one’s chance of being struck by lightning at some point in your life (assuming you live to be eighty) is 1/13,500. That’s almost getting scary.
