Sediment Disposal and Beneficial Use

Consider Beneficial Use with Mud Match

Mud Match is an interactive map viewer and application portal to help entities find each other for a Mud Match that promotes beneficial use rather than open water disposal. Hundreds of thousands of cubic yards of sediment suitable for nearshore placement or beneficial use goes unused every year. Mud Match is an attempt to promote nearshore placement and beneficial use by providing a website to find dredging projects that provide sediment with beneficial use projects that need sediment.

Some information regarding suitability will be provided here but it is the responsibility of each entity to contact each other to determine the details of sediment characterization, transport, and timing.

If beneficial use is not for you, the link below is how to apply for an open water disposal permit.

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.
