And of course each one has to be custom — there’s no such thing as a generic set of rules for an “OK” event.
Pyrotechnics do contain small amounts of potentially poisonous (the dose makes the poison) chemicals that lend colors to the burning sparks. But it would seem a low-brainer to figure out how much is too much. Nobody had ever complained before that fireworks were killing fish or rendering them unfit to eat, etc.
Well, you can set up a zone, do an EIR, then issue permits within that area, so that’s sort of a workaround. They could zone the whole city for fireworks. They’d still have the big-bucks EIR, though, so they probably should also zone it for respiration lest Gonzalez starts complaining about all the “damage” human exhalations are causing the environment.
Mostly what they need to do is just have an Appelate court kick Linda’s ass.
