Announcing the Issuance of a General Permit to Control Zostera japonica on Commercial Clam Beds in Willapa Bay
Permit Issuance: On April 2, 2014, the Washington state department of ecology (ecology) issued a general national pollutant discharge elimination system (NPDES) permit for the control of Zostera japonica (Z. japonica) on commercial clam beds in Willapa Bay. The permit covers the spraying of imazamox on commercial clam beds in Willapa Bay, Washington. The effective date of this permit is May 2, 2014.
Purpose of the Permit: The federal Clean Water Act and Washington's water quality statutes and regulations do not allow the discharge of pollutants to waters of the state without permit coverage. Imazamox, the herbicide proposed for management of Z. japonica is a potential pollutant, and therefore requires a discharge permit before application to surface waters. Ecology issues general permits in place of a series of individual permits when the permitted activities are similar.
This permit would allow the management of Z. japonica on commercial clam beds in Willapa Bay, excluding geoduck culture, using the herbicide imazamox. Commercial clam growers must apply for coverage under this permit prior to implementing Z. japonica control activities using imazamox.
Public Notice Process and Comments: Ecology accepted public comment on the draft permit, fact sheet and draft environmental impact statement from January 2, 2014, until February 15, 2014.
Ecology held a public workshop and hearing in South Bend, Washington on February 1, 2014. Ecology received oral and written comments during the public comment period and responded to these comments in the fact sheet and in the environmental impact statement responsiveness summary. You may download copies of the permit, the response to comments, the fact sheet and the environmental impact statement from the ecology web site at In addition, you may contact water quality program at (360) 407-6400 to request permit documents.
