Grain Elevators
  • Group 1 Registrations
  • Country grain elevators, country grain terminal elevators or grain terminal elevators are classified as Group 1 facilities in 567 IAC 22.10(455B) if the potential to emit of the facility is less than 15 tons of PM10 per year. Owners or operators of Group 1 grain elevators are required to submit a registration form by March 31, 2008 for existing equipment. Click on the link below to check on the status of Group 1 registrations by facility and location. The list is updated weekly on Fridays.

Prevention of Significant Deterioration and Title V Greenhouse Gas Tailoring Rule

On May 13, 2010, the U.S. Environmental Protection Agency (EPA) issued a final rule that sets thresholds for greenhouse gas (GHG) emissions that define when permits under the New Source Review Prevention of Significant Deterioration (PSD) and title V Operating Permit programs are required for new and existing industrial facilities.

  • Fact Sheet - Final Rule (PDF File)
  • Frequently Asked Questions (PDF File) New!
  • Presentation at June 15, 2010 EPC Meeting (PDF File)
  • Proposed Rule Changes New!

    On July 20, 2010 the Environmental Protection Commission (EPC) approved publication of a Notice of Intended Action (NOIA) proposing changes to air quality rules. The purpose of the proposed rulemaking is to assure that sources of greenhouse gas emissions in Iowa are regulated in the same manner and at the same levels as specified in new federal regulations for greenhouse gases, the Prevention of Significant Deterioration (PSD) and Title V Greenhouse Gas Tailoring Rule (Tailoring Rule). The Department is proposing a rulemaking to amend the state’s Title V and PSD air quality rules for greenhouse gas emission regulation such that the state rules match the federal Tailoring Rule. Links to the proposed rules are available below.

    Any person may make written suggestions or comments on the proposed amendments and the associated forms on or before September 14, 2010. Written comments should be directed to Christine Paulson, 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 christine.paulson@dnr.iowa.gov.

    A public hearing will be held on Monday, September 13, 2010, at 1:00 p.m. in the conference rooms at the Department’s Air Quality Bureau office located at 7900 Hickman Road, Windsor Heights, Iowa. At the public hearing, comments on the proposed amendments may be submitted orally or in writing. All comments must be received no later than Tuesday, September, 2010.

    Proposed rulemaking package approved by the EPC on July 20, 2010 (PDF File)

    The Notice of Intended Action will be published on August 11, 2010, in the Iowa Administrative Bulletin.

  • EPA Mandatory Greenhouse Gas Reporting Rule DNR Greenhouse Gas Inventory Reporting Forms and Instructions

    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 http://www.epa.gov/climatechange/emissions/ghgrulemaking.html 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 DNR at 515-281-8468 or marnie.stein@dnr.iowa.gov.

    Emissions Estimate Tools

    The Iowa Department of Natural Resources (DNR) Air Quality Bureau has developed a new guidance document for estimating greenhouse gas emissions from selected stationary sources. The document contains information on data sources, emission factors, and estimation methods that are consistent with the Intergovernmental Panel on Climate Change Good Practice Guidance, the Inventory of U.S. Greenhouse Gas Emissions and Sinks, the California Climate Action Registry's General Reporting Protocol, and EPA guidance. This living document will be updated periodically to incorporate new emission factors and methods as they become available. The document suggests appropriate emission factors and estimation methods; use of specific emission factors is not mandated.

    The Department has revised the Greenhouse Gas Emissions Estimation Guidance to remove Table 5.3 – Fugitive Refrigerant Loss. The table is used by the California Climate Action Registry's General Reporting Protocol to determine whether or not an air conditioning system is significant or de minimis for reporting. However, because the Iowa DNR currently does not have a de minimis reporting threshold, the table has been removed from the guidance as of 10/3/2007.


    Construction Permit Application Assistance

    Starting on July 2, 2007, construction permit applications must include potential greenhouse gas emissions for the project. Applications received without this information will be considered incomplete and the permit(s) cannot be issued until the information has been received. Please note that the Linn County and Polk County air permitting programs are also subject to the same requirements. The following form (Form GHG) has been developed by the Department for the reporting of Greenhouse Gas Emissions for projects:


    Voluntary Greenhouse Gas Registry

    The Climate Registry, click to link...

    The Climate Registry is a nonprofit organization that provides meaningful information to reduce greenhouse gas emissions. The Climate Registry establishes consistent, transparent standards throughout North America for businesses and governments to calculate, verify and publicly report their carbon footprints in a single, unified registry.

    Potential emissions from all processes at Group 2 Grain Elevators should be calculated using the Grain PTE Tool calculations attached in the Iowa DNR Air Quality Construction Permit for Group 2 Grain Elevators.

    Actual emissions from all processes at Group 2 Grain Elevators should be calculated using actual throughput data from the applicable emission year.

    Guidance Documents

    The following two tables list the 187 Hazardous Air Pollutants (HAP's) as defined by EPA. Many of the chemicals regulated as HAP's are also Volatile Organic Compounds (VOC's) because they have volatile and photoreactive properties. Some HAP's are also considered particulate matter (PM). To make this clearer we've added a column that indicates which HAP's are also classified as VOC's or PM.


    This guidance document was developed by the DNR and a committee of representatives from Title V facilities (finalized on 4/14/1997; revised on 6/11/1997 and 6/18/2001). Its purpose is to provide staff and industry with guidance on how to determine what constitutes acceptable periodic monitoring which must be included in each operating permit, as required by 40 CFR Part 70.


    Operation & Maintenance (O&M) plans are sometimes required as part of a source's periodic monitoring. These are example O&M plans for different types of control equipment. It should be noted that these are generic O&M plans, and they may need to be modified to fit a specific source's needs.


    This table identifies typical control efficiencies that would be achieved by different types of control equipment. It is used in reviewing Title V applications by comparing the applicant’s claimed control efficiency with the table’s value. These are conservative control efficiency values that are used in cases where the applicant has not provided further documentation to support a higher control efficiency (e.g. stack test data).

    Glycol ethers is one of 187 listed hazardous air pollutants, as defined by EPA. A frequently asked question the DNR receives is what compounds are included in the glycol ethers category. The guidance document listed below discusses this question, lists a few commonly reported glycol ethers, and refers to an EPA document for further information.

    This document is intended to increase the integrity of lead inventory data from point sources, provide several approaches to calculating lead emissions, and enhance awareness of what processes emit lead.
