Long Island Sound Restoration and Stewardship Reauthorization Act of 2023

This bill reauthorizes federal funding for Long Island Sound restoration and stewardship programs through 2028, extending existing grant programs that support environmental cleanup and community projects in the Long Island Sound watershed. It updates two key provisions: extending the "Long Island Sound Grants" program (under the Federal Water Pollution Control Act) and the "Long Island Sound Stewardship Grants" program (under the 2006 Act) to cover 2024-2028 instead of 2019-2023. The bill does not create new programs or change eligibility but ensures continued funding for states and local organizations already participating in these initiatives. This is a procedural extension, not a policy change to the programs themselves.
