>(you can't built a chemical processing plant in a residential neighborhood, obviously)
You can get darn close in some places. I mean, in Texas, residential damage and evacuations from chemical plant explosions are practically routine. I live in a neighborhood surrounded by biotech labs, which tend not to blow up, though we do joke a bit about being zombie-apocalypse-ground-zero (also, every available developable lot gets sucked up by a new lab project). And of course, in some rural areas, the proximity of farms waste lagoons and low-income neighborhoods is a serious issue.
