This is a waiting-period extension notice for the Final Programmatic Environmental Impact Statement for the Expansion and Modernization of Base Seattle, led by the U.S. Coast Guard. The Final PEIS Notice of Availability was published November 15, 2024, starting a 30-day waiting period that would have closed December 16, 2024. The Coast Guard extended the period to January 10, 2025, citing project complexity and multiple federal holidays. No Record of Decision will issue before that date. Substantive impact analysis is in the underlying Final PEIS, not this procedural notice.12
