United States Environmental Protection Agency | The U.S. Environmental Protection Agency has announced a settlement for alleged violations of the Clean Air Act with Nalco Production LLC and Nalco Co. LLC.

The companies manufacture polymer blend chemicals at their facility at 6216 W. 66th Place in Chicago, Illinois. The companies will pay $401,300 in penalties.

EPA alleges the companies violated requirements to prevent chemical accidents by failing to develop and implement hazard assessments, provide process safety information, secure operating procedures, or conduct periodic inspections on equipment.

EPA also alleges the companies violated requirements to develop incident investigation and risk management plans.

In addition to the monetary penalty, the companies will inspect their ventilation systems and pressure relief valves and add additional sensors. They will update record-keeping practices, including training materials for maintenance staff, and a revised procedure to investigate incidents.
