Rules. Michigan regulates almost 150 wastes as hazardous in addition to those regulated under the federal Resource Conservation and Recovery Act (RCRA) rules. The state's waste determination rules are also more stringent than the federal rules in that Michigan has not adopted all of the waste and hazardous waste exclusions that are available under the federal rules. The state also identifies another hazardous waste characteristic—severe toxicity. In addition, Michigan follows a more stringent mixture rule for mixtures of waste and severely toxic waste.
