If your operation generates industrial wastewater, you have three options:

• Send it to the municipal wastewater treatment plant - contact that authority for permission and to find out what, if any, pretreatment is required
• Treat the wastewater onsite - if discharge to waters of the Commonwealth occurs from the onsite facility following the treatment, then, in addition to the NPDES (part I) permit, a Water Quality Management (Part II) permit is needed. If discharge to the waters of the Commonwealth does not occur following treatment, then no permit (neither NPDES nor Part II) is needed.
• Discharge to a body of water - you need a national pollutant discharge elimination system (NPDES) permit
