Increasing transparency regarding sewage-containing spills.

SB 5450 requires Washington's Department of Ecology to create a public website showing detailed information about sewage spills by July 2026, including spill location, volume, duration, and impacted areas. It also mandates a real-time alert system for the public (with notifications within four hours of a spill report) by July 2027, allowing people to sign up for updates about spills near them. The bill directly affects wastewater facility operators (who must report spills) and the public, including fishermen, aquaculture workers, and recreational users who rely on clean water. The website and annual reports must be accessible to people with limited English proficiency, ensuring transparency about sewage discharges that violate water quality permits.
