Individual Permit for the Control of Burrowing Shrimp using Imidacloprid on Commercial Shellfish Beds in Willapa Bay and Grays Harbor

The Washington State Department of Ecology (Ecology) has issued a new individual permit to regulate the use of imidacloprid for management of burrowing shrimp on commercial oyster and clam beds in Willapa bay and Grays Harbor, a surface water of Washington State. Permit development was requested by the Willapa/Grays Harbor Oyster Growers Association (WGHOGA) to control burrowing shrimp on commercial oyster and clam beds in Willapa Bay and Grays Harbor to aid in the cultivation and harvest of oysters and clams. Additionally, the applicant has applied for a Sediment Impact Zone (SIZ) as the proposed discharge will likely impact sediment quality on sediments where the pesticide is applied.
