Air Plan Approval; IA; Alter Metal Recycling Permit Modification

The Environmental Protection Agency (EPA) is proposing approval of revisions to the Iowa State Implementation Plan (SIP) to include a permit modification for Alter Metal Recycling. The SIP revision addresses modifications to the air construction permit for Alter Metal Recycling included in the State's 2008 Lead (Pb) National Ambient Air Quality Standards (NAAQS) attainment plan for portions of Council Bluffs, Pottawattamie County, IA. These revisions do not impact the stringency of the SIP or have an adverse effect on air quality. The EPA's proposed approval of this rule revision is being done in accordance with the requirements of the Clean Air Act (CAA).
