Air emission inventory submittals are due to the Wisconsin Department of Natural Resources by March 1, 2017. Submittals are made using the WDNR Air Reporting System (ARS). The Air Reporting System allows facilities to report annual air emissions on the Internet using web-based software.
For permitted facilities that cannot submit their emission estimates by March 1, an extension must be requested through the WDNR. Those facilities granted an extension have until March 17, 2017 to submit their emission inventory.
