Your location is identified as Grand Ledge, MI. Utility.net is in the process of completing the design for the system they are building there, but at this time, they don't have any BPL equipment up and running. I don't think that the earlier attempts at getting a BPL system running there were successful, or at least not more than a handful of modems were ever running in Grand Ledge, and they aren't running right now.

BPL systems operate at or near the FCC limits, and those limits will result in quite strong noise locally on any spectrum that the BPL system is using.
Whether that is going to constitute harmful interference will depend on whether there are people trying to use that spectrum. If BPL operates on spectrum that no one is using locally, there is no interference.
In the systems I have seen lately, although the Amateur bands are notched in the US, they are not notched in most installations in other countries. (The industry seems determined to keep repeating its mistakes, it seems). Even in cases where the Amateur bands are notched, I typically see the shortwave broadcast bands un-notched, with "S9+" noise levels, and often CB also has interference.
It is up to the users of that spectrum, however, to file complaints if the experience harmful interfence.
