Emissions Reduction Market System

Based on a recent rule adopted by the Illinois Pollution Control Board, the ERMS rule has been sunset as of April 30, 2018. As such, the submittal of seasonal emissions reports and the trading of ATUs is no longer required beginning with the 2018 season. Source must comply with ERMS requirements prior to April 30, 2018, but are not required to comply for the 2018 season forward. 

What is ERMS?

The ERMS is a "cap and trade" market system in which participating sources must hold "trading units" for their actual VOM emissions. Each year, starting with the 2000 ozone season, participating sources will be issued trading units based on the initial allotment set during issuance of the sources' Clean Air Act Permit Program (CAAPP) permit. For more detailed information, see the ERMS Overview page.
