This final regulation limits the discharge of pollutants into navigable waters of the United States and into publicly owned treatment works (POTWs) by existing and new facilities that formulate, package and repackage pesticide products. This regulation covers two subcategories of the Pesticide Chemicals Point Source Category-- Subcategory C: Pesticide Formulating, Packaging and Repackaging (PFPR) which includes PFPR facilities that also manufacture pesticide active ingredients (PFPR/Manufacturers) and Subcategory E: Agricultural Refilling Establishments. EPA estimates that there are approximately 2,600 facilities in the industry. This regulation establishes effluent limitations guidelines and standards under the Clean Water Act including ``best conventional pollutant control technology (BCT), and ``best available technology economically achievable (BAT)'' for existing direct dischargers, ``new source performance standards (NSPS)'' for new direct dischargers and ``pretreatment standards for existing and new indirect dischargers (PSES and PSNS)''. This regulation also amends and clarifies the limitations based on ``best practicable control technology (BPT)'' for direct discharging facilities. Under the final rule refilling establishments (Subcategory E) will be required to achieve zero discharge of wastewater pollutants. The final regulation provides Subcategory C facilities (herein referred to as ``PFPR facilities'') a choice between zero discharge and the ``Pollution Prevention Alternative.'' This compliance alternative was developed in response to comments on the proposed rule from the industry and has received a large amount of industry support in comments on the supplemental notice. This structure provides a compliance option to facilities who agree to implement certain pollution prevention, recycle and reuse practices. Facilities choosing and implementing the pollution prevention alternative will receive a discharge allowance. The final rule will benefit the env
