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.

Hearings and Workshops: There are two public workshops and hearings scheduled on the draft general permit. The purpose of the workshops is to explain the general permit, explain the changes from the current permit, and answer questions in order to facilitate meaningful testimony during the hearing. The purpose of the hearings is to provide an opportunity for people to give formal oral testimony and comments on the proposed permit. Written comments will receive the same consideration as oral testimony.

October 4, 2010 (1 p.m.) Workshop and Hearing: Lacey Community Center, Banquet Room A&B, 6729 Pacific Avenue S.E., Lacey, WA 98503.

Issuing the Permit: The final permit will be issued after ecology receives and considers all public comments. If public comments cause a substantial change in the permit conditions from the original draft permit, another public notice of draft and comment period may ensue. Ecology expects to issue the general permit in the spring of 2011.
