Emergency Generators

For assistance with compliance regarding the following regulations, contact Occupational Safety and Environmental Health (OSEH) Environmental Protection and Permitting Program (EP3) at (734) 936-1920.
 

Generators are common combustion sources that collectively can have a significant impact on air quality. Air pollutants and toxins emitted from these generators include the conventional pollutants created from fuel burning (carbon monoxide, nitrogen oxides, volatile organic compounds, particulate matter) and toxic substances such as formaldehyde, methanol, and acetaldehyde. Due to the health problems these emissions can cause, the U.S. Environmental Protection Agency (EPA) has air quality regulations that place limits on owners and operators of a wide variety of generators.

In addition to the federal EPA requirements, the Michigan Department of Environmental Quality (MDEQ) may require an air permit. This depends on the function, size, and fuel type of the unit.

Contact OSEH Environmental Protection and Permitting Program (EP3) to determine if a permit is required. The permit must be obtained before ordering the unit.
