Ecology adopts changes to standards for sediment cleanup

OLYMPIA – The Washington Department of Ecology (Ecology) has adopted changes to the state’s standards for cleaning up contaminated in-water sediments. The changes take effect Sept. 1, 2013.

In 1991, Ecology first adopted the Sediment Management Standards (SMS) for guiding the management of sediments. The SMS rule is used to conduct environmental cleanup work, manage the dredging of sediment for navigation and cleanup, and manage sources that contaminate sediment.

In 2012, Ecology proposed changes to the SMS to clarify requirements for cleanup of contaminated sediment sites to make the cleanup process more effective.

Ecology Director Maia Bellon signed the revised rule on Feb. 22, 2013. The newly adopted changes include:

During a lengthy and thorough public process in 2012, Ecology held public hearings on the proposed changes in Seattle, Bellingham, Lacey, Spokane Valley, and Richland. The agency also held a six-week public comment period.

The rule changes do not include a revised fish consumption rate for sediment cleanup projects. Ecology heard a number of concerns about identifying a specific rate, including questions about how it could impact a separate process to update water quality standards.

After reviewing public comments, Ecology decided to clarify that site-specific cleanups use a “reasonable maximum exposure” standard. This is based on protecting Washingtonians who eat large quantities of fish, which in turn will protect all those who eat fish from Washington waters.

An announcement will be published in the State Register on March 20, 2013. The rule will go into effect on Sept. 1, 2013.
