On December 29, 2009 EPA’s Mandatory Reporting of Greenhouse Gases Rule (MRR) became effective. The MRR requires facilities subject to the rule to report their GHG emissions directly to EPA starting with their 2010 GHG emissions data by March 31, 2011. Therefore, DNR will no longer require facilities to report GHG emissions to DNR. Approximately 100 Iowa Title V and ethanol plant facilities are estimated to be subject to the MRR.
Please visit EPA's Greenhouse Gas Reporting Program website to determine if your facility is subject to the MRR reporting requirements. A frequently asked questions document and presentation on the MRR have also been posted on this page under the heading "EPA Mandatory Greenhouse Gas Reporting Rule". If you have questions, please contact the EPA MRR hotline at 1-877-GHG-1188 or GHGMRR@epa.gov, or Marnie Stein of the Iowa DNR at 515-281-8468 or Marnie.Stein@dnr.iowa.gov.
