Rules. Minnesota follows the corrective action rules for hazardous and solid (nonhazardous) waste management units with additional state standards for these units at TSDFs. Minnesota has adopted by reference (with a few state variations) the federal rules for corrective action management units (CAMUs), temporary units (TUs) and staging piles, including 40 CFR 264.555 (placement of CAMU-eligible wastes in off-site hazardous waste landfills), although the state has slightly revised this rule.
