Does a facility with permanently plugged drains in the PFPR process areas have a “potential to discharge”?
No. There is no potential to discharge from the process area. If a facility has no potential to adversely affect a POTW’s operation or violate any pretreatment standard or requirement due to accidental spills, operational problems, or other causes so that no regulated process wastewater can reach the POTW, then the facility is not covered under the PFPR rule.
