"Cooling water" means the clean wastewater from air conditioning, industrial cooling, condensing, and similar apparatus and from hydraulically-powered equipment that is sufficiently clean, uncontaminated, and unpolluted that it can be discharged, without treatment or purification, to a natural open stream or watercourse, subject to the conditions of an NPDES permit.
