Public Meetings to Discuss Proposed SO2 Nonattainment Area in Muscatine County
Posted: 03/15/2013
The Department of Natural Resources Air Quality Bureau (DNR) will hold two public meetings on March 28 at the Muscatine County Conservation Board’s Environmental Learning Center. The purpose of the meetings is to provide information on the proposed nonattainment area for sulfur dioxide (SO2) in Muscatine and to seek input from the public, businesses and other affected stakeholders.

The U.S. Environmental Protection Agency (EPA) has recommended that Muscatine County be designated nonattainment for the 1-hour SO2 National Ambient Air Quality Standard (NAAQS). A nonattainment area is designated when outdoor (ambient) air pollution levels violate the NAAQS. EPA determined that the SO2 monitor located at Musser Park in Muscatine violated the 1-hour NAAQS for SO2 during the period between 2008 and 2010, and has proposed that the entirety of Muscatine County be classified nonattainment.

The DNR has conducted an air quality analysis of the SO2 emissions in the area and will be presenting this information during the public meetings. The DNR is seeking comment on the nonattainment proposal in preparation for response to EPA.

EPA has given the DNR until April 8 to provide EPA with additional information for consideration prior to EPA finalizing the nonattainment recommendation. Additional technical background regarding EPA’s recommendation can be obtained at EPA intends to finalize the nonattainment designations in June 2013.

The first public meeting will be held at 1 p.m., followed by a second public meeting at 6 p.m. The information provided by DNR staff at both public meetings will be the same. The Environmental Learning Center is located at 3300 Cedar Street in Muscatine.

Please contact Jim McGraw at 515-242-5167 or, or Brad Ashton at 515-242-6532 or with questions about the meeting.
