National Pollutant Discharge Elimination System (NPDES) Pesticides - Weed Control

Overview

The State Water Resources Control Board adopted the Statewide General National Pollutant Discharge Elimination System (NPDES) Permit for Residual Aquatic Pesticide Discharges to Waters of the United States from Algae and Aquatic Weed Control Applications, Water Quality Order 2013-0002-DWQ, for the reissuance of General NPDES Permit CAG990005 in June 2013. Order 2013-0002-DWQ became effective on December 1, 2013.

Except for discharges on tribal lands that are regulated by a federal permit, this General Permit covers the point source discharge to waters of the United States of residues resulting from pesticide applications using products containing 2,4-D, acrolein, copper, diquat, endothall, flumioxazin, fluridone, glyphosate, hydrogen peroxide, imazamox, imazapyr, penoxsulam, peroxyacetic acid, sodium carbonate peroxyhydrate, and triclopyr-based algaecides and aquatic herbicides, and adjuvants containing ingredients represented by the surrogate nonylphenol.

This General Permit covers only discharges of algaecides, and aquatic herbicides that are currently registered for use in California, or that become registered for use and contain the above-listed active ingredients and ingredients represented by the surrogate of nonylphenol.

To apply for coverage under Order 2013-0002-DWQ, submit Items 1-3 to the address shown in Item 4 below:

1. A Notice of Intent shown as Attachment E of Order 2013-0002-DWQ, signed in accordance with the signatory requirements of the Standard Provisions in Attachment B;

Exception

Sixth Circuit Court Ruling on National Cotton Council of America v. U.S. EPA (553 F.3d 927 (6th Cir., 2009))
On January 11, 2009, the Sixth Circuit Court of Appeals ruled that pesticide applications at, near, or over water must be covered by an NPDES permit. Thus, algaecide and aquatic herbicide applications in California must be covered by the Aquatic Weed Control Permit currently being implemented under State Water Board Order 2013-0002-DWQ.

State Implementation Policy Exception for Acrolein and Copper
Section 5.3 of the State Water Board Policy for Implementation of Toxics Standards for Inland Surface Waters, Enclosed Bays, and Estuaries of California or SIP allows exceptions to meeting priority pollutant criteria/objectives if the State Water Board or Regional Water Quality Control Boards determine the exception to be necessary to implement control measures either:

1. for resource or pest management (i.e., vector or weed control, pest eradication, or fishery management) conducted by public entities or mutual water companies;
2. for drinking water conducted to fulfill statutory requirements under the federal Safe Drinking Water Act or the California Health and Safety Code.

Dischargers do not need a SIP exception to get covered under State Water Board Order 2013-0002-DWQ. However, since the order allows an exception to receiving water limitations for acrolein and copper, which are the only two priority pollutants regulated by the order, dischargers may apply for an exception at their discretion. To get an exception, dischargers must submit the following information to the address shown in Item 4 above:

1. A detailed description of the proposed action, including the proposed method of completing the action;
2. A time schedule;
3. A discharge and receiving water quality monitoring plan (before project initiation, during the project, and after project completion, with the appropriate quality assurance and quality control procedures);
4. Documentation of compliance with the California Environmental Quality Act;
5. Contingency plans;
6. Identification of alternate water supply (if needed); and
7. Residual waste disposal plans.

Upon completion of the project, the discharger shall provide certification by a qualified biologist that the receiving water beneficial uses have been restored.
