Chemical releases in Michigan are potentially reportable under one or more of twenty-six different state and federal regulations. Determining which regulations apply to a specific release can be an overwhelming task. The "Release Notification Requirements in Michigan" table was compiled by the Michigan Department of Environmental Quality (MDEQ) Office of Environmental Assistance to help owners and operators of facilities in Michigan, including vehicles and farms, determine their potential notification and reporting requirements in the event of a chemical release. Check your permits, licenses, registrations, pollution prevention plans, and local ordinances for additional release reporting requirements.

Citizen's are requested not to physically collect samples or do any actions at a site of concern unless requested by authorities because that could impact a potential civil or criminal enforcement investigation and may place their own health and safety at risk.
