The Pennsylvania Agreement to Revive (PAIR) is an agreement between the Commonwealth of Pennsylvania, the United States Environmental Protection Agency (EPA), and other stakeholders to restore the Chesapeake Bay and its watershed. It was created in 1998 to help reduce pollution and improve water quality in the Chesapeake Bay and its watershed, which includes parts of New York, Pennsylvania, Maryland, Delaware, and West Virginia. The agreement sets out a framework for reducing nutrient and sediment pollution in the region by 2025. It also outlines specific actions that states, local governments, businesses, and individuals can take to help achieve the goals of reducing pollutants and improving water quality. The agreement is supported by the Chesapeake Bay Program, the Chesapeake Bay Foundation, and numerous other organizations. There are two types of Pennsylvania Agreement to Revive: the Chesapeake Bay Agreement and the Susquehanna River Agreement. The Chesapeake Bay Agreement focuses on reducing nutrient and sediment pollution in the Chesapeake Bay, while the Susquehanna River Agreement focuses on reducing nutrient and sediment pollution in the Susquehanna River and its tributaries. Both agreements involve the creation of state-specific action plans that set out specific goals and timelines for reducing pollution.
