EPA is considering two possible modifications to existing regulations: (1) establishing standard National Pollutant Discharge Elimination System (NPDES) permit conditions for publicly owned treatment works (POTWs) permits that specifically address sanitary sewer collection systems and SSOs; and (2) clarifying the regulatory framework for applying NPDES permit conditions to municipal satellite collection systems. EPA will hold public listening sessions and the public can submit written comments. EPA will accept written comments on the potential rule until 60 days after publication in the Federal Register.
