The U.S. Environmental Protection Agency (EPA) is committed to integrating watershed
management into program implementation across a wide range of programs and providing the
necessary tools to ensure innovative approaches to watershed management move beyond the
conceptual phase. In December 2002, the EPA Office of Water Assistant Administrator issued a
policy memo entitled Committing EPAs Water Program to Advancing the Watershed
Approach (USEPA, 2002b). This policy memo not only reaffirms EPAs commitment to the
watershed approach but also reenergizes efforts to ensure that EPA as a whole fully integrates the
approach into program implementation. The memo directs the Agency to accelerate efforts to
develop and issue NPDES permits on a watershed basis. Following the watershed approach
policy memo, EPA released the Watershed-Based NPDES Permitting Policy Statement. This
statement communicates EPAs policy on implementing NPDES permitting activities on a
watershed basis, discusses the benefits of watershed-based permitting, presents an explanation of
the process and several mechanisms to implement watershed-based permitting, and outlines how
EPA will encourage watershed-based permitting. EPA also recently released the Watershedbased
National Pollutant Discharge Elimination System (NPDES) Permitting Implementation
Guidance. This guidance describes the concept of and the process for watershed-based
permitting under the NPDES permit program.
