ACWA Submits Comment Letter on Draft Aquatic Weed Control Permit
ACWA submitted comments Aug. 21 to the State Water Resources Control Board on a draft statewide permit governing aquatic weed control.
The proposed permit, known formally as the Draft Statewide General National Pollutant Discharge Elimination System (NPDES) Permit for Residual Pesticide Discharges to Waters of the United States from Algae and Aquatic Weed Control Applications, covers discharges of residual algaecides and aquatic herbicides from direct applications to surface waters to control algae and aquatic weeds. It is intended to supersede the existing permit issued by the SWRCB in 2005.
Aquatic pesticides are used by urban and agricultural water agencies, reclamation districts and stormwater and flood control agencies to help ensure adequate water quality and water conveyance capabilities for water users statewide.
In its comment, ACWA suggests modifications to address concerns identified by the association’s Aquatic Pesticide Work Group.
“With incorporation of these changes ACWA supports adoption of the Draft Aquatic Weed Control Permit by the SWRCB as soon as practicable, so that it is available for use by water agencies early in 2013 to cover needed applications of the permitted aquatic herbicides,” the comment letter states. “This will help ensure that water agencies can implement best management practices for weed and algae control, and continue to provide clean and reliable water supplies for their customers. ACWA and its members look forward to working with SWRCB staff on implementation of the new permit.”
