Comparison: State vs. Federal

Rules. Illinois has incorporated many of the federal water pollution control requirements into its regulatory scheme. Examples of this incorporation are Illinois's National Pollutant Discharge Elimination System (NPDES) authorization and recordkeeping requirements, and regulations for animal feeding operations and stormwater discharges. See the state section NPDES PERMIT for more information.

In addition to the NPDES permit program, the Illinois Environmental Protection Agency (IEPA) also operates the State Construction/Operating Permit Program. Construction of new sewers, sewage pumping stations, and connections to some large public sewers are covered under this permit program.

Illinois generally follows the federal drinking water regulations and conducts a state groundwater protection program.
