The Washington Department of Ecology has proposed adopting federal water pollution limits to better protect human health by integrating existing federal criteria into state regulations. This rulemaking will not change the current pollution limits but is seen as a necessary step to ensure that the state's regulations align with federal standards. The human health criteria are critical for individuals consuming fish and shellfish and drinking untreated water, addressing nearly 100 pollutants, including toxic substances like methyl bromide, polychlorinated biphenyls (PCBs), and arsenic. This initiative is a response to public feedback from previous rulemakings, indicating a strong desire for the state to prioritize this alignment. Ecology is already utilizing the federal criteria to identify polluted waters and develop cleanup plans, further emphasizing the importance of these regulations.

A final decision on the rulemaking is expected by the end of the year, with an Environmental Justice Assessment included in the process. Public input is actively encouraged, with comments accepted until October 25, 2024. This engagement allows local residents to voice their opinions on water quality and pollution standards affecting their health and environment.
