So if the states enacted the same legislation, everyone would be okay with it?
That question is reactionary and poorly thought out.
First, EPA regulation is not legislation... learn the damn difference.
Second, the west coast states such as California have their own "regulatory" body... which regulates, it don't legislate.
Third, few states would legislate such a thing unless there was a damn good reason or need, they would leave it to the local communities (because, unlike the feds, most state governments actually adhere to their state constitution)... that's exactly why the tree-huggers went crying to the EPA.
Fourth, a city or community may enact a local ordinance to address a local problem (if that's what the majority of residents want), which is part of living in a community... if you don't like it you are a liberty to move somewhere more to your liking (which ain't the case under federal regulation, 'cause there ain't anywhere to move away from it).
Fifth, a state government cannot "regulate" what an industry in another state builds... it can only regulate what is allowed to be sold in their state (in other words, unlike the feds, a state cannot "regulate" an entire industry)... and that flat makes your question invalid and ridiculous.
