New Power Plants and Airports

I just started to notice the following NOTAM for a local airport, Byron, C83

Byron CA [C83]: September NOTAM #246 issued by Oakland CA [OAK]
(O) POWER PLANT 2.7 south EMITTING THERMAL PLUMES avoidance advised 1500 / below

See these great pictures that show the new power plant in relation to the Byron airport as well as a display of the flight paths for a month. As you can see it is close.

In a recent Cal Pilots meeting it was mentioned that they are seeing a number of these new power plants spring up near airports. As I understand, these are not the typical large power plants but are converted jet engines that have a shorter exhaust stak but still generate a thermal plume that can be felt and can impact GA plans. This NOTAM will probably go away once the charts are updated.
