There's a person living near me with a large collection of scrap metal in his yard. Apart from being unsightly, I fear the water running off his yard might be going into a near by river and carrying rusty colored water with it. As far as I know he doesn't have a license or permits to collect scrap metal. He also has a large amount of building material dumped near by, concrete, gravel etc which contains bits of insulation and plastic which is blowing around the place.
I would like to know how to approach this situation.
Thanks.
