The bill aims to improve water quality in Puget Sound by addressing the significant issue of nutrient discharges from municipal wastewater systems. It establishes a requirement for operators of these systems to submit annual reports detailing any discharges of untreated or partially treated sewage, including their locations, volumes, and impacts on water quality. The Department of Ecology is tasked with compiling these reports into a summary that will be disseminated to the media and the legislature, providing transparency on the state of water quality in Puget Sound.

Additionally, the bill mandates the Department of Ecology to continue providing technical assistance to local governments and wastewater treatment operators in reducing nutrient discharges. It emphasizes the importance of identifying funding opportunities and making grants available for projects aimed at reducing these discharges. The department is instructed to prioritize funding for the most cost-effective and expedient projects, ensuring that the financial burden of improving water quality does not fall solely on local governments and utility ratepayers.
