PUBLIC NOTICE

Public Workshop and Hearing to Accept Comments on the Proposed Modification of the General Permit for Aquatic Weed Control in Irrigation Systems



The department of ecology is proposing to renew and modify the "irrigation system aquatic weed control national pollutant discharge elimination system (NPDES) and state waste discharge general permit" in March 2012. The modified draft permit and fact sheet are available for review and public comment from February 15, 2012, to March 30, 2012. The department of ecology will host an informational workshop and public hearing on its proposal. The public is encouraged to give written comments during the public comment period or oral comments at the public hearing.

Purpose of the Permit: The general permit covers the discharge of pesticides used in irrigation systems in Washington state to control plant and algae growth. The proposed permit addresses legal requirements under the Washington State Water Pollution Control Act and regulates the discharge of pollutants to protect water quality. Proposals for modifications to the permit include changes for endothall (Cascade and Teton) and fluridone. The effective use of endothall enables less use of the more toxic acrolein. The draft permit includes other proposed changes.

The department of ecology issues a general permit in place of a series of individual permits for similar permitted activities. Individual activities that receive coverage under the general permit must comply with the terms and conditions of the permit.

Requesting Copies of the Permit: You can request copies of the proposed permit and fact sheet by contacting Laurie Morgan at the department of ecology at the address below. The proposed permit modification and fact sheet are also available on-line at http://www.ecy.wa.gov/programs/wq/pesticides/irrigation/irrigation_index.html.
