There are new documented claims that the popular fireworks shows over SeaWorld are polluting Mission Bay and the surrounding beaches. San Diego Coastkeeper and the Coastal Environmental Rights Foundation have sent a letter of notice of intent to sue SeaWorld. The environmental advocates say the company routinely discharges plastic caps, wires, trash and other chemical covered debris into Mission Bay in violation of its fireworks permit. “Our view is they are not allowed to use this bay as a dumping ground for their fireworks shows, and as basically a garbage dump for their poorly treated wastewater, which they’re suppose to treat,” said Phillip Musegaas, executive director of San Diego Coastkeeper. SeaWorld produces approximately 150 firework displays during the year. The shows originate with explosives being ignited from a barge in the middle of the Mission Bay waters surrounding Fiesta Island. It’s a popular area for beachgoers and visitors looking to ski and paddle boat. There is also numerous wildlife.
