The Michigan Freedom of Information Act (FOIA) provides all persons (except persons incarcerated in correctional facilities) with access to public records of public bodies. Requests to inspect or receive public records from EGLE must be in writing and describe the requested records with enough detail to enable the department to identify and locate the requested records. Some records are exempt from disclosure under the FOIA or another statute and thus will not be provided. A fee may be charged to process your request. Please note that many records are available that do not require a formal FOIA request.

Every year Air Quality Division (AQD) staff respond to hundreds of air quality complaints from Michigan residents. Complaints are typically about strong odors, smoke, and dust from industrial sources. In 2024, almost 1,700 air quality complaints have been lodged, with 84% of complaints stating strong odors are impacting them. Many complainants voice concerns about health impacts, like headaches and nausea. Studies have shown that some odors can have health impacts, so investigating odor complaints is important. Examining diverse odors in variable situations requires staff to be trained to understand odors and how to analyze and document them.
An inspector will use a defined Odor Scale to document an odor investigation. This scale and its proper implementation establish the foundation for odor investigations. The 0-5 scale requires the inspector to rate the odor from “0 – Non-detect” to “5 – odor so strong as to be overpowering and intolerable for any length.” Staff also incorporate the frequency and duration of the odors into their investigation. But how are these determinations made? This is where Odor School comes in.
Air Quality Division staff attend Odor School
Odor school provides a foundation for the science of odors, how the body receives and processes odors, and methods for identifying and characterizing odors. These provide a common foundation for air quality staff to understand the science and help consistently implement the AQD complaint investigation policy. At Odor School, staff learn about odor management and how the sense of smell works. They study odor chemistry and hear how odor source testing is done in a lab. Information on the science of odors is important as some pollutants can be detected at very low concentrations in the outdoor air. Staff must be able to identify the odor, accurately describe it, and document it per the odor scale.
At Odor School staff share their experience with odors through case studies and best practices of odor complaints that have been successfully investigated. The most successful cases are those that led to the reduction of odors from a regulated source and relief for residents in the area. The AQD studies odors to be confident in what the nose knows.
