Really now.
Cameo Power Station shut down in 2010.
https://www.coloradonuclearatlas.org/site/former-cameo-power-plant/mill-tailings Many go there to use the outdoor shooting ranges. They have cleaned the whole place up and there is no hint of any coal fired plants anymore.
Nucla Power Station is to be retired by Dec 2022 but the coal to run it was shut down in 2019 which effectively shuts it down. When you retire a Coal Fired Power Plant that means that the clean up has been completed. The Shutdown date is when it no longer produces power. The last time I was in Nucla (just up the road from here same county) there were a lot of construction going on to get rid of all hint that there ever was any coal powered factory there.
That leaves the two in Craig which are being operated at 18% capacity until 2025 which then are to be completely shutdown. And it will be completely retired (cleaned up) by 2028. There is talk about shutting them completely down at the end of this year and going for clean up. There really isn't any reason to have them in operation anymore.
