Project Title & Description
State Definitions and Requirements for Ephemeral, Intermittent and Perennial Streams
The purpose of this project is to identify and compare the various ways states address jurisdiction, identification and protection of ephemeral, intermittent and perennial streams. The project will document how states identify streams for regulatory purposes, comparing the estimated extent of waters covered from state to state. In addition it will also describe methods for mitigating stream alteration and degradation under the state permitting programs and through conditioning of Section 404 program permits (using 401 certification) to identify best practices states can use to address gaps in federal Clean Water Act jurisdiction. Case studies will be developled and published summarizing the varied tools used by states nationally.
