Ecology is proposing to revise certain portions of the Sediment Management Standards (Chapter 173-204 WAC). This rule defines the requirements for managing contaminated sediments in Washington. This rulemaking will include:
Updates to the Sediment Management Standards (SMS) cleanup decision framework to address bioaccumulative chemicals which present risk to human health and the environment. This includes methods and policies for establishing risk-based cleanup standards, procedures for incorporating background concentrations, and requirements for sediment cleanup actions.
Fish and shellfish consumption rates used to support cleanup decisions.
Chemical and biological criteria to support cleanup decisions at freshwater sediment sites.
Clarifying requirements for coordinating cleanup actions and source control measures to prevent recontamination.
