BPL pollutes the HF radio spectrum, filling huge swaths with beeping and screeching noises that make radio unusable. The HF spectrum is finite. It has some amazing properties that allow communications around the world with relatively low power.

If BPL were polluting the air you breathe or water you drink even a fraction of the way it pollutes the radio spectrum, people would be screaming foul to the EPA!

The FCC is charged with keeping the airwaves clear the way the EPA is with our environment. The FCC is quite content to ignore their own rules and the complaints from licensed services that are continuously subjected to this harmful interference. The FCC should enforce the rules, and ban further BPL trials until the operators can prove that they no longer pollute the radio spectrum.
