• Rules. The North Carolina Department of Environmental Quality (DEQ) adopts by reference the federal rules at 40 CFR 260.10 and exemptions for neutralizing hazardous waste in North Carolina, including the federal definitions of "elementary neutralization unit" (ENU) and "treatment." The treatment of corrosive wastes in an ENU, as defined by the Resource Conservation and Recovery Act (RCRA), exempts facility owners and operators from needing a hazardous waste treatment permit and from complying with regulations applicable to hazardous waste treatment, storage, and disposal facilities, provided certain conditions are met. Hazardous waste generators neutralizing their corrosive wastes immediately on-site in an ENU do not need to count such wastes in their monthly determination of how much hazardous waste has been generated.
• Administration and enforcement. DEQ's Division of Waste Management administers and enforces the federal hazardous waste neutralization rules in North Carolina.
