H.R. 4275 would authorize appropriations totaling $455 million over the 2020-2024 period for the Environmental Protection Agency’s (EPA’s) Chesapeake Bay Program. That program provides technical assistance and grant funding for projects and programs aimed at restoring the Chesapeake Bay. In 2019, EPA received appropriations totaling $73 million to carry out the program.
Assuming appropriation of the specified amounts and based on historical spending patterns, CBO estimates that implementing the bill would cost $405 million over the 2020-2024 period and $50 million after 2024. The costs of the legislation, detailed in Table 1, fall within budget function 300 (natural resources and environment).
