With the release of the 2024 Municipal Stormwater General Permits in July 2024, there is an updated 2024 Stormwater Management Manual for Western Washington (SWMMWW). Phase I Permittees have until July 1, 2026 and Phase II Permittees have until June 30, 2027 to adopt the Ecology manual or an equivalent one. This presentation will discuss the changes made between the 2019 and 2024 manuals, cover the New Development and Redevelopment Flow Charts and their place in determining the application of the nine Minimum Requirements, address UIC updates, discuss each of the nine Minimum Requirements, and provide information on Ecology interpretations of the manual.
