On Wednesday, bipartisan legislation was approved in the Senate Environment and Public Works Committee to withdraw the final Clean Water Act rule and directs Environmental Protection Agency and the Corps of Engineers to rewrite the rule after considering numerous modifications.  S. 1140 does not mandate rule provisions but instead provides guidance to the agencies to redefine tributaries and adjacent waters and to exempt existing systems for wastewater treatment, water recycling, storm water, and water delivery.  The legislation will move to the full Senate when bill sponsors are convinced that they have at least 60 votes to support the bill.
