This Congressional Review Act resolution sponsored by Rep. Sam Graves nullifies the Biden administration’s revision of the definition of “waters of the US.” Had the executive branch been left to its own devices, the new definition would have overruled the old 2020 definition by expanding it to include certain wetlands and ephemeral waters. This measure, in turn, would have greatly increased the regulatory power of the EPA and associated entities. CPAC opposes large increases in the regulatory powers of the EPA, opposes major increases in regulatory burdens on American citizens, and supported this resolution. The Senate passed this resolution on March 29, 2023 by a vote of 53-43.
