This legislation aims to ensure the continued operation and funding of the National Estuary Program . It achieves this by amending the Federal Water Pollution Control Act, specifically Section 320(i)(1), which governs the program's authorization. The bill extends the authorization for appropriations for the National Estuary Program, pushing the expiration date from fiscal year 2026 to fiscal year 2031 . This reauthorization provides crucial federal support for the long-term protection, restoration, and management of nationally significant estuaries across the United States.
