Equipment Registration applications (see "Download" sidebar) must be submitted for the installation of air pollution sources such as combustion (heating) equipment, process (manufacturing) equipment, air pollution control equipment, storage tanks and land remediation processes in suburban and unincorporated Cook County.

If you are submitting an Air Construction Permit to the  Illinois EPA, please also submit a separate copy directly to the Cook County Department of Environment and Sustainability.  

For additional information on equipment installation application requirements and fees, refer to Sections 30-151 to 30-164 and Section 32-1 of the Municipal Code, or contact our office at (312) 603-8200.

As of December 1, 2017, the Cook County Department of Environmental Control is now the Department of Environment and Sustainability.
