Sediment Disposal and Beneficial Use

 

DNR manages Washington dredging in cooperation with other state and federal agencies.

Application Requirements

Before dredgers may take dredged material to one of DNR's unconfined open-water dredged material disposal sites, they must obtain a valid Site Use Authorization (SUA) from the DNR's DMMP office. View DNR's Application Instructions and Site Use Application for obtaining a SUA.

Reporting Requirements

DNR is committed to protecting the aquatic environment through stringent oversight of all disposal activities occurring under a SUA. DNR accomplishes this by imposing specific reporting requirements for every load of dredged material taken to one of DNR's unconfined open-water dredged material disposal sites. Disposal Site Report Use and Monthly Disposal Statement forms, once completed, may be submitted via email, fax courier, or mail.

Fees

Users of any DNR's unconfined open-water dredged material disposal sites must pay disposal fees, which are assessed at a per cubic yard rate and subject to a minimum application fee. These fees are authorized under RCW 79.105.520, and under WAC 332-30-166. View the current Fee Structure.
