Stakeholder workgroup icon. What is the Odor Workgroup?

The Department of Natural Resources is convening a workgroup to examine the state's odor regulations. This workgroup will examine the department's Air Pollution Control Program odor regulations to determine if changes are needed. This action is being done in response to a petition received by the Air Program and in response to concerns expressed by others about the regulations. Odor complaints typically are among the most common complaints received by the Air Program. The workgroup is composed of representatives from industry, environmental groups, regulatory agencies and other interested parties.

The last significant change to the odor regulations occurred in 1999 and brought Class IA Concentrated Animal Feeding Operations, or CAFOs, under the odor rules. The impetus for the change was the growing presence of large commercial animal agriculture operations in the state. The 1999 rulemaking was conducted through a workgroup process and put Missouri on the leading edge of addressing odor concerns from Class IA CAFOs.

Stakeholder meeting icon. Summary of Workgroup

The Odor Workgroup concluded its efforts on June 26, 2007. The workgroup examined the state's existing odor regulations and discussed possible changes to those regulations. At the conclusion of the workgroup a final report was prepared detailing specific issues and possible courses of action. The final report is available below and a presentation was given at the Missouri Air Conservation Commission meeting on July 26, 2007, in Jefferson City.

The Missouri Air Conservation Commission, or MACC, continued their discussion of the state’s odor regulations at a commissioner’s workgroup on Feb. 6, 2008, and at their regularly scheduled meeting on Feb. 7, 2008. On Dec. 4, 2008, the commission requested staff to develop draft language to incorporate several elements. After receiving public input to finalize the rule language the commission adopted the proposed rulemaking on July 28, 2010. The rule became effective on November 30, 2010.

Odor Investigation Results
This report is about the initial odor investigation designed to determine specific chemical elements in the nuisance odors experienced by citizens in Carthage to help in identifying the source or sources of odors. This first phase involved an innovative approach that combines evaluation of the odor by the human nose along with a chemical analysis. Don Wright of Microanalytics™, performed the initial phase of the investigation, which was funded by the department.

Leanne Tippett Mosby
The workgroup has engaged in a fair amount of discussion on how odors are investigated. There have also been some concerns raised about the large volume of complaints related to PSF that are not investigated individually. This issue was raised at the Missouri Air Conservation Commission and the Air Pollution Control Program provided the following information. A letter to the Washington University Interdisciplinary Clinic on the same subject is also listed.
