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

The Individual Permit for the Control of Burrowing Shrimp using Carbaryl on Commercial Shellfish Beds in Willapa Bay and Grays Harbor is a combined National Pollutant Discharge Elimination System (NPDES)and State Waste Discharge Permit. It allows the use of the pesticide carbaryl to control burrowing shrimp (Neotrypaea californiensis and Upogebia pugettensis) on commercial shellfish beds in Willapa Bay and Grays Harbor.

NOTE: The proposed permit for the use of imidacloprid to control burrowing shrimp (Neotrypaea californiensis and Upogebia pugettensis) on commercial shellfish beds in Willapa Bay and Grays Harbor is separate from this permit, which allows the use of carbaryl for the same purpose. For more information about the proposed imidacloprid permit see: Proposed Individual Permit for Burrowing Shrimp Control using Imidacloprid on Commercial Shellfish Beds in Willapa Bay and Grays Harbor.

new content NOTE: Due to the timely and sufficient reapplication submitted to Ecology by the Willapa Bay Grays Harbor Oyster Growners Association, the individual permit for Contol of Burrowing Shrimp using Carbaryl on Commercial Shellfish Beds in Willapa Bay and Grays Harbor remains in effect until Ecology either terminates the permit, or issues a replacement permit (WAC 173-220-180).
