and sources of information for developing watershed based plans to improve and
protect water quality. This document refers to statutory and regulatory provisions

particular situation based upon the circumstances. EPA, state, territory, local
government, and authorized tribe decision makers retain the discretion to adopt
approaches on a case-by-case basis that differ from this guidance.
Interested parties are free to raise questions and objections about the
appropriateness of the application of the guidance to a situation, and EPA will
consider whether or not the mendations in this guidance are appropriate in
that situation. EPA may change this guidance in the future.
