NPDES Public Agency Notification
for Aquatic Weed Control

The State Water Resources Control Board (SWRCB) Water Quality Order 2013-0002-DWQ permit regulates applications of algaecides and aquatic herbicides, including the residual discharges to Waters of the United States. The permit requires that potentially affected public agencies are notified each year applications are to be carried out.   

Under permit enrollee number 5B20AP0002, Madera Irrigation District (District) intends to apply algaecides and aquatic herbicides during the 2016 water season between March and September. The applications are intended to reduce aquatic vegetation within the District water distribution system that adversely affect canal capacity and water quality. The algaecides and aquatic herbicides that may be used are Acrolein, Copper, Diquat Dibromide, Endothall, Fluridone, Glyphosate, Imazamox, and Penoxulam. In addition to these items, various aquatic-labeled adjuvants maybe be used.

Madera Irrigation District completed a California Environmental Quality Act Initial Study and Mitigated Negative Declaration, and was granted a State Implementation Plan Section 5.3 exception. The exception was granted by the SWRCB for short-term discharge of copper-containing aquatic herbicides registered in California to surface waters in excess of the California Toxics Rule priority pollutant criteria.
