Comparison: State vs. Federal

· Rules. Maine has adopted the federal rules for generators of hazardous waste and added more stringent state provisions. In addition, because the state does not use the federal definitions of large quantity generator (LQG), small quantity generator (SQG), and conditionally exempt small quantity generator (CESQG), Maine's rules are more stringent for generators that under the federal scheme would be considered SQGs or CESQGs.
