Mandatory categories are categories of project types that require environmental review. Each mandatory Environmental Assessment Worksheet (EAW) and Environmental Impact Statement (EIS) category is defined in rule. The rule lists applicable project thresholds and assigns the responsible governmental unit who conducts review. Information gathered through the Minnesota environmental review process is intended to assess and disclose information on potential environmental effects prior to the approval of any governmental action. The Environmental Quality Board (EQB) is completes a legislatively mandated report on the environmental review mandatory categories every three years.
