This document provides information to states on a pilot approach for voluntarily listing impaired waterbodies within subcategory 5R (R for Restoration) on their Clean Water Act (CWA) Section 303(d) and Section 305(b) Integrated Reports. The 5R subcategory acknowledges that many state Total Maximum Daily Load (TMDL) programs face significant resource limitations that may hamper the development of implementable TMDLs, which may delay water quality restoration. The 5R subcategory provides states with flexibility in how they apply their limited resources to achieve water quality standards. Region 4 offers the 5R approach to states as a 6-year pilot where they partner with stakeholders to implement water quality restoration activities prior to TMDL development.You may need a PDF reader to view some of the files on this page.
