I think he wants them not to dump the chemicals straight down the sewer?

FWIW, I don't see anywhere that the parent post said that there shouldn't be plating plants in San Jose, just that they are dangerous.

Yes. It's a miserable business. Look at the pictures from the inspection of a plating plant. Everything near the process is corroded and covered with crud. Such plants have to be regulated and inspected, to prevent them from becoming a hazard both to the neighborhood and downstream.

Plants which do chemistry on an industrial scale tend to need their own waste processing, which gets the waste products down to a reasonably neutral form. Regulation is needed to prevent dumping it unprocessed. That's what the EPA really does.

ok but I'm willing to have occasionally poisoned water in exchange for an industrial society
