Public Hearing to Discuss Proposed Fine Particulate Control Strategy in Muscatine
Posted: 05/21/2013
The Department of Natural Resources Air Quality Bureau (DNR) will hold a public hearing on June 24 at 2:00 p.m. at the Muscatine City Hall Council Chambers, 215 Sycamore St., in Muscatine. The purpose of the hearing is to receive oral and written comments on the State of Iowa’s state implementation plan (SIP) for fine particulate matter (PM2.5) in Muscatine, Iowa.

An electronic copy of the SIP document may be viewed at Click on Inside DNR, then select Regulatory-Air. Next select Stakeholder Involvement, followed by Public Input. The documents will be located under the Area or Company Specific Plans portion of the Webpage. A hardcopy version of the documents may also be viewed at the Musser Public Library, located at 304 Iowa Avenue, Muscatine, Iowa. 

In 2011, the U.S. Environmental Protection Agency (EPA) Region 7 found that the Iowa’s SIP was substantially inadequate to maintain the 2006 24-hour National Air Quality Standard (NAAQS) for PM2.5 in Muscatine. This finding was published in the Federal Register (76 FR 41424) on July 14, 2011, and was effective on August 15, 2011. EPA’s finding required the State to revise the SIP and include measures to attain and maintain the 2006 24-hour PM2.5 NAAQS in Muscatine. The DNR collaborated with facilities in Muscatine to develop air pollution control measures that will result in expeditious attainment of the 24-hour PM2.5 NAAQS through reductions of ambient air impacts of PM2.5 emissions.

Any person may make written comments on the proposed SIP revisions by June 25, 2013. Written comments on the draft SIP should be directed to Jim McGraw, Department of Natural Resources, Air Quality Bureau, 7900 Hickman Road, Suite 1, Windsor Heights, Iowa, 50324, fax 515-242-5094, or by electronic mail to All comments must be received no later than 4:30 p.m. on June 25, 2013.

A separate public hearing will be held at 1:00 p.m., also at the Muscatine City Hall Council Chambers, to receive oral and written comments on changes to air construction permits for Muscatine Power and Water. The permit changes allow for the establishment of PM2.5 emission limits in the permits as part of the Muscatine PM2.5 SIP control strategy. Drafts of these permits can also be viewed at the webpage location specified above. A hardcopy version of the draft air construction permits may also be viewed at the Musser Public Library. Written comments on the draft air construction permits should be directed to All comments must be received no later than 4:30 p.m. on June 25, 2013.
