Shoreline Management Act Permits.  The Shoreline Management Act of 1971 requires that most developments near state shorelines be consistent with shoreline master programs, which are local land-use policies and regulations for the uses of its shoreline areas.  Some projects require a substantial development permit that is reviewed by the local government and filed with the Department of Ecology (Ecology) which includes:

• developments exceeding a cost of $7,436.87—as adjusted for inflation by the Office of Financial Management in December 2020; or
• any development that materially interferes with the normal public use of the water or shorelines of the state.

In certain property-specific circumstances, local government may issue variance permits or conditional use permits allowing for development, which may be inconsistent with a local shoreline master program.

Dredged Material Management Program.  The Department of Natural Resources (DNR) is responsible for stewarding more than 2.6 million acres of state-owned aquatic lands and manages them to provide a balance of public benefits for the state.  The aquatic lands managed by DNR includes tidelands, shorelands, harbors, and the lands lying beneath navigable waters.
 
The Dredged Material Management Program is a coordinated, multi-agency approach to manage materials dredged from harbors, rivers, and shipping lanes to be disposed of at certain aquatic land disposal sites.  The approval of sites derives from a cooperative process involving Ecology, DNR, the Army Corps of Engineers, and the United States Environmental Protection Agency (EPA).  Currently, there are eight approved dredged material disposal sites in Puget Sound, two sites in Grays Harbor, and two sites in Willapa Bay.
 
Before dredged material may be taken to a disposal site, a dredger must apply to DNR's Dredged Material Management Program office for a site use authorization.  DNR only issues site use authorizations after:

• all other applicable federal, state, and local permits have been acquired by the proponent; and
• Ecology and EPA notify DNR that the dredged materials are suitable for disposal under the federal Clean Water Act and do not appear to create a threat to human health, welfare, or the environment.

 
Dredging proponents must pay a per-cubic yard disposal fee, adopted in rules by DNR, to use a disposal site.  Disposal must occur consistent with conditions imposed by DNR in the site use authorization, which include the terms and conditions imposed by any other federal, state, and local permits.
 

The Legislature passed HB1480 in 2019, which streamlined the permitting process for disposing dredged materials.  It created an exemption disposing dredged materials at disposal sites that were approved through the Dredged Material Management Program.  This exemption is provided if the proponent of the disposal obtains a DNR valid site use authorization.

The sites used for federal navigation channel maintenance and improvement projects and activities are exempt from the Shoreline Management Act's permit requirements and Washington State Department of Transportation's maintenance permits.
