I just looked at your map and it is scary to see AEP plants to be closed. I know people who worked at those plants!
I retired from an AEP coal plant a few years back. They use low sulfur Wyoming coal and the plant is extremely clean.
The EPA is now requiring them to install scrubbers to remove that miniscule amount of sulfur left, and install a bag house.
The problem is, the Public Service Commission will not allow them to pass along the cost of building the EPA mandated scrubbers. So the plant may be shut down and abandoned.
Yeah, you never know when that last molecule of sulfur might bump into a human somewhere along the way. /s
