In addition, any water treatment additive (WTA) that is discharged to a surface water of the state from an National Pollutant Discharge Elimination System (NPDES) permitted discharge requires prior review and approval by the WRD.  Pesticides used for controlling mosquito larvae in waters discharged under NPDES permits are considered WTAs.   Requests to perform pesticide treatment in wastewater treatment systems and catch basins covered by an NPDES permit must originate from the permittee and be made under the Water Treatment Additive approval process.

For applications of pesticides to catch basins and/or waters in a storm sewer system or wastewater treatment system that are covered by a National Pollutant Discharge Elimination System (NPDES) permit, an approval under the  Water Treatment Additive  approval process is necessary.  This includes municipalities, industries and storm water sewer systems under the Phase I and Phase II storm water regulations.
