NPDES State Program Withdrawal Petitions
EPA has authorized 46 states and the U.S. Virgin Islands to implement the NPDES program. During routine oversight activities, EPA and the states identify ways in which the states can improve their program administration.
Under EPA's regulations, citizens may petition EPA to withdraw a state's authority to administer the NPDES program. When EPA receives such a petition, EPA generally works with the state and the petitioner to resolve the issues that the petition raises and strengthen the state's NPDES program.
Below, you may search for pending and resolved NPDES withdrawal petitions by state, region, date, or keyword. You may also sort the petitions according to their status.
- "Pending" indicates that 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- "Withdrew petition" means that the petitioner has withdrawn the petition.
- "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- "Program withdrawn" would apply if, after conducting investigations, EPA withdrew a state's NPDES authority.
