Public comment period extended for proposed rules for stack testing and portable plants
Wednesday, May 23, 2012
The DNR is extending the public comment period for air quality rule changes to reduce regulatory requirements by limiting emissions testing to federal test methods. The proposed rule changes would also allow portable plants like concrete batch plants to have less lead time and use email to submit relocation notices, providing more flexibility for owners and operators.

The DNR received a request to extend the comment period to allow more time for stakeholders to provide comments. In response to this request, the DNR is extending the deadline for public comment from May 18, 2012, to July 3, 2012

To review the proposed rule changes, go to the DNR’s air quality public input website (scroll down to Administrative Rules). Or go to the DNR’s air regulatory website at Click on Stakeholder Involvement on the menu on the left side, and then click on the link for Public Input

The DNR welcomes all comments. The DNR held a public hearing on Friday, May 18. The DNR is not scheduling any additional hearings at this time. Other than extending the comment period, the DNR is currently not proposing any changes to the rulemaking. 

The DNR must receive all written comments no later than 4:30 p.m. on Tuesday, July 3, 2012. 

For questions or to provide comments, please contact Christine Paulson at or by phone at (515) 242-5154. Written comments may also be sent to Christine Paulson by fax to (515) 242-5094 or by delivery to Iowa DNR Air Quality Bureau, 7900 Hickman Road, Suite 1, Windsor Heights, Iowa 50324.
