The city parks department is working to remedy the violations and believes the fines will be waived when that is done, deputy parks director Jen Pittman said.
"In addition to addressing the orders at Garfield Park, Indy Parks and Recreation also plans to evaluate all of the city's aquatic centers and take corrective action as necessary before the facilities reopen next spring," Pittman said.
The June chemical reaction at the pool on the city's south side resulted in about 70 people, mostly children, going to hospitals for treatment of symptoms including nausea, breathing problems and watery eyes.
A city review found that a park employee didn't reopen a valve following a routine backwash of the pool. That set off a chain of events that allowed two pool chemicals to combine into chlorine gas and enter the pool.
The pool reopened several days later after city officials said repairs were made and its procedures for handling chemicals were updated.
The state safety report classified six violations at the pool as serious.
Inspectors found the pool's circulation system had inadequate flexible tubing that leaked and exposed employees to corrosive chemicals. The report also said the pool didn't have proper gloves and flushing equipment for workers and had some unsafe electrical outlets.
