The purpose of the bill is to reaffirm Congress’ commitment to restore and maintain the chemical, physical and biological integrity of the nation’s waters, as called for in the Clean Water Act (CWA) and to overturn the Trump administration’s WOTUS rule.  The legislation directs the EPA and the Army Corps of Engineers to develop a new rule within two years of enactment to prevent degradation of surface water quality; increased contaminant levels in drinking water sources; increased flooding-related risks to human life or property; and disproportionate adverse impacts on minority or low-income populations.
