EPA regulations are put in place after tracking down data, study and experimentation. Nothing is arbitrary. Regulations aren't pulled out of someone's a$$.
But when Republicans get rid of environmental regulations, it's not based on study or data, it's based on what they think costs too much.
Can you see how this will lead to disaster?
You just admitted to the mentality that turned the EPA into a terrorist organization: they don't believe cost is an obstacle.
Only environmental nutburgers believe you don't need to consider the cost of implementing their industry killing regulations. That's why we elected Trump, to clean these idiots out of the EPA.
