OPERATOR. The person who has operational control of the real property, including an operator or person who is in charge of any activity related to land disturbance, construction, or post- construction stormwater quality or quantity.
OUTFALL or DISCHARGE POINT. The point where a city stormwater management system or facility, or other municipal and private system, discharges into waters of the State or United States.
OWNER. A property owner, or any person who acts in his or her behalf, who submits an application for approval to disturb land or vegetation or for encroachment, and the person, if so designated
