About Certificates of Operation (COO)
Please note that in accordance with Section 30-186 of the Cook County Municipal Code, “A current certificate of operation shall be required for any person to use or operate any fuel-burning, combustion, process equipment, process, or air pollution control device.”
Payment for a certificate of operation is required if your commercial or industrial facility operates any fuel-burning, combustion, process equipment, process, or air pollution control device. Price is determined based on equipment type, the amount of fuel burned, and the amount of fuel stored on-site.
For instance, fees are assessed for each piece of fuel burning equipment that has the potential to generate 1,000,000+ BTUs annually, on-site fuel storage of 250+ gallons and each piece of non-fuel burning equipment (i.e. control devices and process equipment). Invoices are sent annually via email.
All payments for your Certificate of Operation (COO) shall be submitted through the electronic permit processing portal. Enter the required information from the Statement of Account that you received.
