About this program
The Environmental Protection Agency funds water quality protection, habitat restoration, and living resources management in Long Island Sound through the Long Island Sound Program, Assistance Listing 66.437, with the most recent grant award on October 1, 2026.
The program implements Connecticut and New York's Comprehensive Conservation and Management Plan (CCMP) to restore and protect Long Island Sound's water quality, habitat, and living resources. Funded activities span water quality monitoring (hypoxia surveys, pathogen tracking, coastal acidification measurements), habitat restoration (salt marsh recovery, dam removal, living shoreline projects), river connectivity improvements, nitrogen removal infrastructure upgrades at wastewater treatment facilities, property acquisition for coastal habitat protection, competitive research programs administered by Sea Grant programs, and community engagement and environmental justice initiatives targeting underserved communities in the watershed.
The program distributed 186 awards totaling $379 million in federal obligations (combined total of $538.5 million with recipient cost-share) since 2002. Award activity has been consistent, averaging 7.2 awards annually over the past five years (12 in 2025, 6 in 2024, 8 in 2023, 9 in 2022). Grants are predominantly Project Grants (87 percent, 162 awards) with a smaller share of Cooperative Agreements (13 percent, 24 awards).
EPA Region 1 leads funding concentration with $211.2 million across 41 awards, followed by EPA Region 2 with $89 million across 23 awards, and the EPA national office with $78.8 million across 122 awards. Recent awards reflect the program's scope: the National Fish and Wildlife Foundation received $20.6 million to administer the Long Island Sound Futures Fund (competitive subawards for restoration and protection projects); Connecticut Department of Environmental Protection received $13.7 million for water quality monitoring, habitat coordination, and acoustic telemetry of migratory fish; and Massachusetts Department of Environmental Protection received $10.6 million for wastewater treatment nitrogen removal upgrades in the Long Island Sound watershed.
