Ecology Department hosts meeting in Raymond about Japanese eelgrass

OLYMPIA — The state Department of Ecology will hold an informational public meeting about a proposal allowing shellfish growers to use herbicide to control non-native Japanese eelgrass that has colonized commercial clam beds in Willapa Bay.

The growers asked Ecology to develop a permit for the use of the aquatic herbicide imazamox.

The permit would be a National Pollutant Discharge Elimination System (NPDES) general permit issued by Ecology. It would not cover geoduck culture and it would only be allowed on commercially managed clam beds in Willapa Bay.

Ecology will hold a public informational session at 1 p.m., Dec. 6, at Riverview Education Center - Room 101, Grays Harbor College, 600 Washington Ave. in Raymond.

Japanese eelgrass is listed as a noxious weed. For more information visit the Washington State Noxious Weed Control Board (

Ecology will hold further public involvement opportunities while the permit is being developed.
