Public notice to deny permit

Tentative determination on NPDES aquatic pesticide permit

April 9, 2018 - May 14, 2018

We have tentatively determined to deny the permit for the proposed new discharge of imidacloprid. We invite you to submit written comments on our tentative decision. 

The Willapa-Grays Harbor Oyster Growers Association Willapa Bay (WGHOGA) applied for a National Pollutant Discharge Elimination System (NPDES) permit in accordance with the provisions of Chapter 90.48 Revised Code of Washington (RCW), Chapter 173-220 Washington Administrative Code (WAC), and the Federal Clean Water Act. WGHOGA proposes to apply the pesticide imidacloprid to control burrowing shrimp on 500 acres of commercial shellfish beds in Willapa Bay and in Grays Harbor, Washington.

  We regulate aquatic pesticides released into water under the National Pollutant Discharge Elimination System (NPDES) Permit. This permit regulates when, where, how, and the amount and type of products that can be applied. The permits provide details on the monitoring, reporting, and public notification requirements for using pesticides to manage aquatic organisms.

Para solicitar información en español acerca de la decisión tentativa para denegar este permiso, por favor comuníquese con Rich Doenges a burrowing.shrimp@ecy.wa.gov ó 360-407-6271.
