and storm water. discharged from buildings or facilities where commercial or industrial activities
take place.
C4.2.22. Inhabitant Equivalent (IE). A unit of measure indicating the biodegradable
organic load having a BOD5 (5-day biochemical oxygen demand) equal to 60 grams (21 ounces)
of O2 per day. The capacity of a wastewater treatment system is expressed in IE. This value
should not be substituted for the number of people served by the wastewater treatment system.
C4.2.23. Interference. Any addition of any pollutant or combination of pollutant
discharges that inhibits or disrupts the DWTS, its treatment processes or operations, or its sludge

C4.2.25. Point Source. Any discernible, confined, and discrete conveyance, including (but
not limited to) any pipe, ditch, channel, tunnel, conduit, well, discrete fissure, container, or
rolling stock; but not including vessels, aircraft, or any conveyance that merely collects natural

C4.2.27. Process Wastewater. Industrial wastewater which during manufacturing or
processing, comes into direct contact with, or results from the production or use of, any raw
material, intermediate product, finished product, by-product, or waste product.
C4.2.28. Reclaim. Treatment of wastewater for reuse.
C4.2.29. Regulated Facilities. Those facilities for which criteria are established under this
Chapter, such as treatment systems for domestic, industrial, and urban wastewaters.
C4.2.30. Reuse. The use of reclaimed wastewater instead of abstracted surface/or
groundwater (partially of totally). Reclaimed wastewater has to meet specific quality standards
and to be supplied through a distribution network.
C4.2.31. Sensitive Areas. Include the following water systems:
C4.2.31.1. Natural lakes, fresh waters, estuaries, and coastal waters, eutrophic or subject
