As part of the EPA's "Ozone Layer Protection Milestones of the Clean Air Act" information page, an United States federal government agency (and thus public domain) artist/artists produced an amazing vector city that should not be lost in the maze of government bureaucracy. I am liberating here an isolated item. Anonymous artist at the EPA, you are appreciated and glorified! :)
This is a chemical plant.
(Note that not all bits are exactly the same as original EPA work, some colours and lines etc have been changed/cleaned up while synthesizing for release on openclipart.org etc etc)
