PUBLIC NOTICE

Final Issuance of the Modified Aquatic Plant and Algae Management General Permit

аааа Permit Modification: The Washington state department of ecology (ecology) issued a new modified aquatic plant and algae management general permit (permit) April 4, 2012. The permit is a joint national pollutant discharge elimination system (NPDES) and state waste discharge general permit. The permit covers the discharge of products used to control aquatic plants and algae in Washington lakes. The permit also allows treatment of emergent plants along roadsides and ditch banks. Control products include aquatic herbicides, algaecides, biological clarification products, aquatic dyes, adjuvants, and nutrient inactivation products such as alum.

аааа Purpose of the Permit Modification:

Х The modification adds four new Environmental Protection Agency (EPA) reduced-risk herbicides to the permit. Information about these four herbicides is found in ecology's recent Environmental Impact Statement for Penoxsulam, Imazamox, Bispyribac-sodium, flumioxazin, and Carfentrazone-ethyl - Addendum to the Final Supplemental Environmental Impact Statement for Freshwater Aquatic Plant Management at http://www.ecy.wa.gov/programs/wq/pesticides/final_pesticide_permits/noxious/docs/eis100511.pdf. Ecology updated Table 3 in the permit to include the new herbicides and added a sign template for each new chemical.

Х Ecology updated Table 2 - Listed adjuvants based on new information from the Washington state department of agriculture about which adjuvants met their criteria for aquatic toxicity.

Х Ecology added a sign template for nutrient inactivation products and clarified that permittees do not need to post signs for continuous alum treatments.

аааа Purpose of the NOI Modification: Ecology added a statement about treatment timing windows and included a checkbox for applicants to request a timing window change.
