Comparison: State vs. Federal

Rules. Both Massachusetts and the U.S. Environmental Protection Agency (EPA) define hazardous waste treatment to include neutralization of wastes. However, unlike the federal definition, the state's definition of treatment of hazardous waste includes the permit exemption for hazardous waste neutralization units. Note that Massachusetts's permit exemption for neutralization units is more restrictive than the federal exemption. In order to qualify for the permit exemption in Massachusetts, neutralization units must meet stringent construction standards.
