The bill aims to enhance transparency regarding sewage spills in Washington State by establishing a public notification system and a dedicated website for reporting such incidents. It mandates the Department of Ecology to develop a public-facing website by July 1, 2026, which will provide real-time information about sewage spills, including details such as the volume of discharge, treatment level, and geographic areas affected. Additionally, the department is required to update this information following the conclusion of a spill and ensure the website is accessible to individuals with limited English proficiency.

Furthermore, the bill requires the implementation of a public notification system by July 1, 2027, which will inform the public within four hours of a sewage spill during regular business hours. The Department of Ecology must also publish an annual report by March 15 each year, detailing sewage spills reported in the previous calendar year, including information on impacted waters and actions taken. This legislation is designed to protect public health and environmental quality by ensuring timely access to information about sewage spills that may affect communities and ecosystems.
