New permits may be required after Super Bowl show trashed beach

San Francisco Chronicle

State officials are mulling whether to require new permits for firework companies after pyrotechnic debris washed up on parts of San Francisco’s shoreline after two Super Bowl shows. . .  In the wake of the cleanup efforts, San Francisco Baykeeper is now urging regional water agency officials to require Clean Water Act permits for companies to launch fireworks. “We haven’t heard of this kind of debris coming onto the shore during our 26 years watch-dogging the Bay,” said Sejal Choksi-Chugh, director of the group.
