North Carolina General Statutes Chapter 90A. Sanitarians and Water and Wastewater Treatment Facility Operators § 90A-37. Classification of water pollution control systems

The Commission, with the advice and assistance of the Secretary of Environmental Quality, shall classify all water pollution control systems. In making the classification, the Commission shall give due regard, among other factors, to the size of the system, the nature of the wastes to be treated or removed from the wastewater, the treatment process to be employed, and the degrees of skill, knowledge and experience that the operator of the water pollution control system must have to supervise the operation of the system so as to adequately protect the public health and maintain the water quality standards of the receiving waters as assigned by the North Carolina Environmental Management Commission.
