Illinois: Air
The Illinois Environmental Protection Agency adopted amendments to 35 Ill. Adm. Code 274, Clean Air Set-Aside. This rulemaking addresses procedural rules for implementing the nitrogen oxide (NOx) allowance portion of the Clean Air Interstate Rule (CAIR) clean air set-asides. The rulemaking sets forth procedures for eligible sources and entities to apply for CASA NOx allowances, for the Illinois EPA to distribute such allowances, and for maintaining a website that lists the allowances available, application deadlines, and other relevant information. The changes became effective April 6, 2009.
