If you are a dry cleaner, your business probably generates some hazardous waste, mostly perchloroethylene (perc). That means you must follow regulations issued by the State of Delaware. Under the Delaware Regulations Governing Hazardous Waste, you are required to follow certain practices and procedures associated with the safe management of hazardous waste.
• Correctly identify all hazardous waste (i.e. perc, perc/water mixture, dry cleaning machine filters).
• Keep all perc, perc/water and filters in appropriate containers.
• Always label containers with the words “Hazardous Waste”.
• Always keep hazardous waste containers closed unless in use.
• Utilize pollution prevention techniques where applicable.
• Contact local publicly-owned treatment works (POTWs) before discharging solvent-containing wastewater.
• Have a licensed hazardous waste transporter pick up the hazardous waste containers generated at your facility.
• Maintain all hazardous waste manifests for at least three years.
• Store perc, perc/water mixture or filters in cracked or inappropriate containers.
• Store used dry cleaning machine filters in cardboard boxes.
• Boil perc wastewater unless using certified distillation units.
• Dispose of perc waste in the trash.
• Mix perc waste with non-hazardous waste.
• Store hazardous waste containers in unsafe or unsecure areas.
