US Supreme Court Could Require Permits for Urban Runoff

On December 4  the US Supreme Court will hear arguments on whether municipalities will be required to obtain NPDES permits for the pollutants that run off from their streets and buildings through their municipal separate storm  sewer systems, orMS4s, into nearby rivers. The case,  Los Angeles County Flood Control District v. Natural Resources Defense  Council,  is an appeal from a decision of the Ninth Circuit US Court of Appeals  in which the City (County?) of Angels  was ordered to obtain permits for its discharges of runoff into the Los Angeles River. Roderick Walston has a great analysis of the case and the legal issues involved, and I invite you to check it out to learn more about them.

Legalities aside, this is a tough nut to crack  politically.  MS4s can be major contributors to water quality violations, but requiring  NPDES permits for this type of runoff will  likely result in higher taxes to pay for the  treatment needed to meet discharge limits.
