Environmental regulators say a Salem-area dry-cleaning business spilled a toxic solvent into the city's sewer system.
Peacock Cleaners has been closed for six months, and its owner tells the Salem Statesman Journal that he did nothing wrong.
But officials with the state Department of Environmental Quality say the business improperly disposed of a dry cleaning solvent known as "perc."
Perc is considered a hazardous waste under Oregon law.
Agency officials have levied a more than $4,000 dollar fine on the business, which the owner is appealing.
The EPA says that wearing clothes dry-cleaned with perc does not pose a health risk.
