Announcing the Modification of the Zostera Japonica Management on Commercial Clam Beds in Willapa Bay General Permit
PERMIT: The Washington state department of ecology (ecology) is modifying the Zostera japonica management on commercial clam beds in Willapa Bay general permit (permit). This permit modification becomes effective on May 18, 2017, and expires May 2, 2019.
State and federal water quality regulations do not allow the discharge of pollutants to waters of the state without permit coverage. Herbicide products used for management of Zostera japonica (Z. japonica) are potential pollutants, and therefore require a discharge permit before application to dewatered clam beds. Ecology issues general permits in place of a series of individual permits when the permitted activities are similar.
PURPOSE OF THE PERMIT: This permit regulates the discharge of the aquatic herbicide imazamox for the purpose of managing the noxious weed Z. japonica on commercial clam beds in Willapa Bay. The permit covers all Z. japonica management activities that result in a discharge of aquatic herbicides containing the active ingredient imazamox and maker dyes from treatment of commercial clam beds to surface waters of the state of Washington. Coverage under this general permit will be available to pesticide applicators with an aquatic license and their sponsor who plan to use imazamox to control Z. japonica on commercial clam beds in Willapa Bay.
PERMIT AND SUPPORTING DOCUMENTS: Ecology accepted public comment on the draft permit modification and fact sheet addendum from December 7, 2016, until March 7, 2017. Ecology held a webinar and public workshop and hearing in Lacey, Washington, on January 24, 2017, and a public workshop and hearing in South Bend, Washington, on January 26, 2017. Ecology received oral and written comments during the public comment period and responded to these comments in an addendum to the fact sheet.
You may download copies of the permit, the response to comments, and the fact sheet from the ecology web site at You may also request hardcopies of the documents from Nathan Lubliner at or (360) 407-6563.
