The bill amends RCW 90.48.080 to modify the standards for determining water quality pollution in the state of Washington. Specifically, it makes it unlawful for any person to discharge organic or inorganic matter into the waters of the state that causes pollution, as determined by the department.

A key change in the legal language is the deletion of the phrase "tend to" from the existing law, which clarifies that the focus is solely on whether the discharge causes pollution rather than merely having the potential to do so. This amendment aims to strengthen the enforcement of water quality standards and enhance the protection of the state's water resources.
