A federal judge in Missouri has given her approval to a consent decree that requires the Metropolitan St. Louis Sewer District to make billions of dollars in improvements to settle Clean Water Act violations.
A ruling from the Missouri Court of Appeals is a mixed bag for the Metropolitan St. Louis Sewer District.
The decision today is the latest in a series of rulings on a storm water "user charge" the agency implemented in 2007. The charge was based on the impervious area of a property, and replaced a system of a flat tax that could be enhanced by additional taxes in 21 sub-districts.
