Comparison: State vs. Federal
• Rules. Michigan's regulations defining characteristic waste are the same as the federal. The Department of Environmental Quality (DEQ) has additional rules that identify a fifth hazardous waste characteristic called "severe toxicity."
• Administration and enforcement. DEQ's Office of Waste Management and Radiological Protection administers and enforces the rules for characteristic hazardous waste in Michigan.
MAC r 299.9208 and MAC r. 299.9212
Along with the characteristics of ignitability, corrosivity, reactivity, and toxicity (as identified in the federal regulations), DNRE identifies the characteristic of severe toxicity (MAC r. 299.9212 (5)).
A waste exhibits the characteristic of severe toxicity if it contains 1 part per million or more of a severely toxic substance listed in MAC r. 299.9219, Table 202.
