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.
