Philadelphia’s 1995 Litter – Creek Trash Mistaken Impression and Today’s Street Litter

Philadelphia, as part of Appendix C of the PaDEP-Philadelphia 6/1/11 Consent Order and Agreement (COA), is required to continue implementing EPA’s Combined Sewer Overflow (CSO) Nine Minimum Controls (NMC) (link), including NMC #7 Pollution Prevention Programs to Reduce Contaminants in CSOs.


EPA’s 1995 CSO NMC Guidance document (Chapter 8) outlines 10 nonstructural options that EPA encouraged CSO cities to consider in addressing solids and floatables pollution prevention. These 10 NMC #7 techniques are:

  • Street Cleaning (more frequent in high litter areas)
  • Public Education Programs
  • Solid Waste Collection and Recycling (including trash receptacles, more frequent pick-ups in litter problem areas)
  • Product Ban/ Substitution (fast food packaging)
  • Control of Product Use
  • Illegal Dumping
  • Bulk Refuse Disposal
  • Hazardous Waste Collection
  • Water Conservation
  • Commercial/ Industrial Pollution Prevention
