| The Illinois Pollution Control Board, a
sister Agency to the Illinois EPA, promulgates water quality standards
in Illinois. Two Sections of 35 Illinois Administrative Code (IAC),
Section 302, Water Quality Standards and Section 303, Water Use Designations
and Site Specific Water Quality Standards contain the standards applicable
to lakes and streams. Procedures to be followed in using water quality
standards to set NPDES permit limits are found in Section 309. Other
implementation procedures are found in Agency Rules. |
