The bill aims to enhance transparency regarding sewage spills 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 include a mapping interface displaying the locations of reported sewage spills, along with detailed information about each incident, such as the volume of discharge, treatment level, and public safety precautions. Additionally, the department is required to retain this information indefinitely on the website and ensure that it is accessible to individuals with limited English proficiency.

Furthermore, the bill requires the implementation of a public notification system by July 1, 2027, allowing the public to receive alerts about untreated or undertreated sewage spills within four hours of the department's receipt of a notice. The department must also provide an annual report detailing unauthorized spills or discharges, starting March 15, 2026, and continuing each year thereafter. This report will include information on the impacted waters, duration, volume, and actions taken by the department in response to the spills.
