## Abstract

EPA is approving revisions to particulate matter control requirements for rural grain elevators in Illinois. On April 8, 1999, the Illinois Environmental Protection Agency (IEPA) submitted section 9 of the Illinois Environmental Protection Act (as revised by Public Act 89-491) as a requested revision to the Illinois State Implementation Plan (SIP). The requested SIP revision exempts rural grain elevators from certain particulate matter control requirements. An air quality modeling analysis was conducted to show that this rule change would not cause or contribute to violation of the National Ambient Air Quality Standards (NAAQS) for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM10).
