NPDES General Permit Aquatic Pesticide Application

U.S. Environmental Protection Agency (EPA) has released a proposed new permit with requirements that would regulate the amount of pesticides discharged to Waters of the US. This proposed general permit is in response to an April 9, 2009 court decision that found that pesticide discharges to U.S. waters were pollutants, and therefore requiring an NPDES permit.

The proposed permit would require all operators to reduce pesticide discharges by using the lowest effective amount of pesticide, prevent leaks and spills, calibrate equipment and monitor for and report adverse incidents. Additional controls, such as integrated pest management practices, are built into the permit for operators who exceed an annual treatment area threshold.

The agency plans to finalize the permit in December 2010, and have it take effect April 9, 2011.
