I just looked, and you're right. It's in an industrial area several km from homes, and near existing NG facilities, including one where they flare gas.

I don't doubt that it is a source of pollution, but I agree that this is overblown in the same was as the claims that datacentres are using up all the fresh water.
It's not overblown. That plant has sufficient pollution filters installed. You can find more info elsewhere in this comment section.
But it's still not localized to the one neighbourhood in the Time article any more than any other in Memphis (or even West Memphis across the river).
