Hazardous Waste Management

William & 玛丽 generates hazardous and non-hazardous waste from maintenance, laboratory and studio activities. As a registered small quantity generator, all chemical waste generated in University laboratories and other facilities must be disposed of in accordance to the guidelines and regulations mandated by the Virginia Department of Environmental Quality (DEQ) and Federal Environmental Protection Agency (EPA).

Guidelines

Hazardous waste must be properly labeled at all times. The moment waste is added to a container, the container must be labeled with the following:

  1. The words “Hazardous Waste.”
  2. The proper chemical name of all the contents. Name must be identifiable in order to alert emergency responders of the contents and for those handling hazardous waste to make an accurate determination for disposal.
    • Trade names, acronyms, abbreviations, or formulas are not acceptable (e.g. “Ethanol” instead of “EtOH”).
  3. Hazards associated with the contents.
    • Hazards can be found in the Safety Data Sheet Library or on the label of the original container from the supplier.
    • Use pictograms, the National Fire Protection Association (NFPA) diamond or signal words to communicate the hazards.
  4. The date the container has been filled, not started filling. This is called “the accumulation start date” or “satellite accumulation area fill date.”

Waste Pickup

Before requesting a hazardous waste pickup:

  • Determine if you can reuse or recycle this waste in the laboratory, facility or studio. If so, there is no need to dispose of the material through the Hazardous Waste Management Program procedures.
  • Attempt to find another user of any unopened or uncontaminated containers in acceptable form. This will avoid the cost and environmental impact of disposal.
  • Separate solids and liquids. All liquids must be free of solid material or sludge to facilitate consolidation, recycling and proper disposal. If solids cannot be separated from liquids, the identification and quantity of the solid component must be listed on the Hazardous Waste Disposal Request Form.
  • Consolidate similar wastes into as few containers as possible.
  • Properly package the waste. If existing container is incompatible with the material inside, transfer material to a new container. Containers must be leak free, have a tight cap and be clean on the outside. Stoppers and corks are not acceptable. Containers should be no more than 90% full to avoid spills.
  • Prepare the waste containers for pickup by ensuring all labels meet the above requirements, and place waste in a centralized or satellite area within the facility, laboratory or studio.
  • Complete the hazardous waste disposal form.
  • Once the form is submitted, all waste will be picked up within three days.
  • If waste has not been properly prepared for pickup, the online form will be returned to the generator and must be resubmitted once the waste is adequately prepared.
