The Montana Federal District Court ruled that it would be more efficient to address total maximum daily loads (TMDLs) on a watershed basis than by individual waterbodies. The decision made in Friends of the Wild Swan, et al. v. EPA, et al. amended a 2004 court order that required Montana to address all waterbodies listed in the state’s 1996 list of impaired waters by the end of 2012. The recent federal court decision gave the state an additional 2 years to achieve compliance, but included waterways not listed as impaired in the 2004 court order.
