District Headquarters Announcements

On February 14, 2019, the U.S. Environmental Protection Agency (EPA) and the Department of the Army (Army) published for public comment a proposed rule revising the definition of “waters of the United States,” which would establish the scope of federal regulatory authority under the Clean Water Act (CWA). The proposed rule is intended to satisfy the requirements of Executive Order (EO) 13778 that directed the EPA and the Army to review and rescind or replace the 2015 Clean Water Rule (80 FR 37053) and consider interpreting the scope of “waters of the United States” consistent with the Justice Scalia opinion (plurality standard) from Rapanos v. United States (2006).
Observed every February, National African American/Black History Month celebrates the contributions African Americans have made to American history in their struggles for freedom and equality, while further deepening our understanding of our Nation's history. The theme for 2019 is “Black Migrations” and the observance theme is developed each year by the Association for the Study of African American Life and History (ASALH).
