   "SHALL" is mandatory (See "MAY").
   "SLUG." Any discharge of water or wastewater which in concentration of any given constituent or in quantity of flow exceeds for any period of duration longer than 15 minutes more than five times the average 24-hour concentration or flows during normal operation and adversely affects the collection system or performance of the wastewater treatment works.
   "STORM DRAIN" or "STORM SEWER." A drain or sewer for conveying water, groundwater, subsurface water, or unpolluted water from any source.
   "STORM WATER." Any flow occurring during or following any form of natural precipitation and resulting therefrom.
   "SUPERINTENDENT." The Superintendent of Public Works or his authorized deputy, agent, or representative.
   "SURFACE WATER." Water that occurs when the rate of precipitation exceeds the rate at which water may percolate into the soil.
   "SUSPENDED SOLIDS." Total suspended matter that either floats on the surface of, or is in suspension in, water, wastewater, or other liquids, and that is removable by laboratory filtering as prescribed in "Standard Methods for the Examination of Water and Wastewater" and referred to as nonfilterable residue.
