Amendments to the Effluent Limitations Guidelines, Pretreatment Standards, and New Source Performance Standards for the Organic Pesticide Chemicals Manufacturing IndustryPesticide Chemicals Point Source Category
EPA is promulgating amendments to regulations that limit the discharge of pollutants into navigable waters of the United States and into publicly owned treatment works (POTWs) by existing and new sources that manufacture pesticide active ingredients (PAIs). Today's amendments only affect new and existing facilities that manufacture the PAI pendimethalin. These amendments are based on additional effluent monitoring data submitted to the Agency by the sole existing pendimethalin manufacturer, the American Cyanamid Company.
