The Chicago Area Waterway System and Lower Des Plaines River
				  standards protect primary contact, incidental contact, or non-contact
				  recreational uses (except when designated as non-recreational waters);
				  commercial activity, including navigation and industrial water supply uses; and
				  the highest quality aquatic life and wildlife that is attainable, limited only
				  by the physical condition of these waters and hydrologic modifications to these
				  waters. The numeric and narrative standards in this Part will assure the
				  protection of the aquatic life, wildlife, human health, and recreational uses
				  of the Chicago Area Waterway System and Lower Des Plaines River as those uses
				  are defined in 35 Ill. Adm. Code 301 and designated in 35 Ill. Adm. Code 303.
				  Indigenous aquatic life standards are intended for the South Fork of the South
				  Branch of the Chicago River (Bubbly Creek), which is capable of supporting an
				  indigenous aquatic life limited only by the physical configuration of the body
				  of water, characteristics and origin of the water and the presence of
				  contaminants in amounts that do not exceed the water quality standards listed
				  in this Subpart D. However, the Chicago River is required to meet the general
				  use standard, including the water quality standard for fecal coliform bacteria
				  applicable to protected waters in Section
				  302.209.
