If it is directly affecting you--e.g. you live adjacent to the pile up, or else have a store, office, business, that *you* own adjacent--you could try filing a lawsuit based on the creation of a "nuisance." However, nuisance suits can be slow and expensive, so this may not be a practical measure. You could also try to pressure the government to act, either by going to local representatives or the mayor's office and complaining, or going to local media.
