Program objective
The Chesapeake Bay is a national treasure and unique as North America's largest and most biologically diverse estuary. The objective of the Chesapeake Bay Program’s competitive assistance agreements is to fund activities that support achievement of the goals and outcomes of the Chesapeake Bay Watershed Agreement. Funding priorities include, but are not limited to, implementation projects that support water quality improvement and environmental stewardship, coordination of the Chesapeake Bay Program partnership, monitoring and modeling of the Chesapeake Bay and its ecosystem, and advancement of data science that helps inform decision-making. EPA supports advancement of these priorities by funding cooperative agreements, which support the partnership in carrying out the Chesapeake Bay Watershed Agreement and fulfilling the statutory requirements of the Chesapeake Bay Program Office under Clean Water Act Section 117. Additionally, EPA funds cooperative agreements to intermediary organizations for the purposes of carrying out the Small Watershed Grants (SWG) grants program, which supports protection and improvement of local waterways while building citizen-based resource stewardship; and the Innovative Nutrient and Sediment Reduction (INSR) grants program, which supports regional innovative solutions to reduce or eliminate nutrient and sediment pollution.
