The Department of Environmental Quality proposed amendments to 15A N.C. Admin. Code 02D .0540, .1802, .1806, and .1902 to .1904. The proposed amendments would, among other things, redefine best management plan requirements for the control of odors from animal operations and other process facilities, and revise requirements for open burning and air curtain incinerators, including revising definitions to clarify different activities, clarifying which items can be burned, and incorporating changes to federal emissions guidelines and standards outlined in 40 C.F.R.
