Published by U.S. EPA Office of Water (OW) - Office of Wastewater Management (OWM) | U.S. Environmental Protection Agency | Metadata Last Checked: July 31, 2025 | Last Modified: 2012-12-12
Search for pending and resolved NPDES withdrawal petitions by state, region, date, or keyword. "Pending" means EPA has received the petition and is working with the state and petitioner to resolve it. "Withdrew petition" means that the petitioner has withdrawn the petition they submitted. "Resolved" means that EPA has resolved the issues raised in the petition and has denied the petition. "Partially resolved" means that EPA has partially denied the petition by resolving some of the issues, while continuing to work with the state and petitioner on other pending issues. "Program withdrawn" would apply if, after conducting investigations, EPA withdrew a state's NPDES authority.
