Sediment Management Standards, Chapter 173-204 WAC
The Sediment Management Standards (SMS) Chapter 173-204 WAC is the rule
we use to manage sediment in the state of Washington. The SMS rule is used
The goal of the SMS rule is to reduce and ultimately eliminate adverse
effects on biological resources and significant threats to human health from
surface sediment contamination. The SMS rule was originally adopted in 1991
with subsequent amendments in 1995 and 2013.
2013 SMS Rule Amendments
Ecology adopted the revised Sediment Management Standards rule on February 22, 2013. The new rule will become effective on September 1, 2013.
The adopted amendments:
SMS Rule Implementation
Ecology is currently developing tools to support implementation of the revised rule. This includes:
Guidance. Updating the Sediment Cleanup Users Manual II (SCUM II) guidance document to reflect the 2013 SMS rule changes. A preliminary draft of SCUM II was developed and posted during the SMS rule public comment period in September 2012 to help reviewers understand how the proposed rule amendments were intended to be implemented. This preliminary draft is being completed and a draft will be available in September 2013 for public review and comment.
Regional Background. Establishing Regional Background for sediment in select embayments in Puget Sound. A key provision in the 2013 SMS rule is the concept of regional background in sediment and establishing regional background is a high priority for Ecology. Regional background will be used to determine the upper cap for sediment cleanup levels, inform cleanup decisions, and identify potential areas of sediment contamination that may require cleanup. Learn more about Ecology’s efforts to establish regional background.
Communication and Outreach. Conducting outreach to communicate the provisions in the revised SMS rule with the public, interested stakeholders, and local, state, and federal governments. This includes:
