Not true. Tennessee is down wind from Arkansas and Texas and states further west. What Kentucky puts in the rivers flows through our state. What's states up north put in the rivers flows down the Mississippi.
EPA does need to be a central authority. States weren't doing the job before the EPA.
But I'll say it again, there are abuses, and it needs to be reined in. Maybe the whole rule making authority where agencies propose new or tighter rules and Congress rubber stamps them needs to be rethought and changed.
That is what the federal courts are for....interstate disputes.
