Baldwin worked with vegan charity PETA to write a letter citing animal neglect allegations accrued by the chain.
He also rose concerns around 'enforcement actions taken by a state finance department, a state wildlife agency, a state agriculture department, and local code enforcement - associated with SeaQuest's owner, Vince Covino, or his other aquariums'.
'Cruel and deadly'
"The owner of this sleazy chain, Vince Covino, has not only flouted the law nearly everywhere he goes but also left untold animal suffering in his wake," Baldwin wrote in the letter.
"I urge you to deny the permit application that would allow Vince Covino to bring his cruel and deadly operation to our lovely hamlet."
PETA added: "SeaQuest's history of animal mistreatment includes an instance at the Colorado location when, in an apparent effort to circumvent permit requirements, the company reportedly gave 80 birds to a teenage employee who later gave them away for free in a Lowe's parking lot."
