Top Waste Compliance Issues

  • Fixer & developer - Silver can cause a local wastewater treatment infraction; and be a hazardous waste issue
  • Solvents - Total consumed count towards Clean Air Act permit status; can be a hazardous waste
  • Fountain Solution - Total consumed count towards Clean Air Act permit status; can be a hazardous waste
  • Ink - Total consumed count towards Clean Air Act permit status; can be a hazardous waste

Top Things An Inspector Looks For

  • A Hazardous Waste Inspector will look for proper labeling of product and waste containers
  • A Hazardous Waste or a Air Inspector will look for open/closed containers of volatile or hazardous materials
  • A Hazardous Waste, Air, Water or OSHA (different agency) Inspector will look for availability and accessibility of MSDS information
  • A Hazardous Waste Inspector will look for drips, stains, spills and puddles.
  • All inspectors (A Hazardous Waste, Air, Water or OSHA (different agency) Inspector) will look for and question personnel to determine operator knowledge of hazards & risk
  • All inspectors will look for responsible party's knowledge of regulations
  • All inspectors will look at your Compliance history
  • All inspectors will can and may request supporting information for regulatory status
  • All inspectors will keep an eye open for the most common violations (ex. see OSHA's top 10 Violation list)
  • A Hazardous Waste Inspector will look for failure to make a hazardous waste determination
  • A Hazardous Waste Inspector will look for illegal disposal of a hazardous waste
  • A Air Inspector will look for Improper determination of "potential to emit" VOC's, HAPs, and particulates.
