I recently ran into a homeowner installed Radon Mitigation system. The discharge pipe was right on the front of the house through a wall blowing out within 20-inches of the door and close to a window. Anyone else run into Radon Removal Systems that are not "legit" with regard to the EPA specs?

I thought you couldn't mount the blower I side the house ether. Looks like a home owner install to me.

I see you live in Minnesota (which abuts Canada as does my own home state). I recently viewed a Mike Holmes video related to radon mitigation at https://www.youtube.com/watch?v=UnqIPtZt3Go.

Some of the features of your example closely resemble those in the Holmes' video. The home owner might have used a similar reference source to design his own. The interior fan and exhaust below roof line are very similar.

I live in Wisconsin and had a radon migration system installed last year. The installer told me the fan could not be placed in a living area of the house. The basement, finished or not could not contain the fan. Acceptable locations were, in the attic, garage, or outside. Also the vent pipe needed to be mounted 10' from the ground. I wonder if these rules are different from state to state?

EPA guidelines, although somewhat dated, provide the basis for construction requirements of radon mitigation systems. The fan cannot be mounted in the home's conditioned envelope. The exhaust must be at least 10' above ground, and above the home's roof line. There are several more, of course.

I have not read of any licensed state which has retracted the installation requirements suggested by the EPA.
