Kanto Corporation, a Portland chemical manufacturer, failed to report the use of toxic chemicals at its facility in violation of community right-to-know laws, according to a settlement with the Environmental Protection Agency announced Thursday. Kanto agreed to correct violations of the federal Toxics Release Inventory Program and pay a fine, according to the EPA. Kanto is at 13424 North Woodrush Way.

EPA found Kanto used more than 25,000 pounds each of ammonia, hydrogen fluoride and nitric acid in 2009, the announcement said. These toxic chemicals can affect the eyes, skin and respiratory system. Under the settlement, the company has resolved the violations and will pay a penalty of $58,200, the EPA reported.

Companies must report certain toxic chemical releases, transfers and waste management activities under the Toxics Release Inventory Program.
