100.00 Hazardous Materials Management


110.00 Regulations

  • Collection - You must call the HMM facility to arrange for pickup of wastes. Collections are made once/week, usually on Tuesday.
  • Packaging
    1. Containers must have secure covers or caps.
    2. Leave sufficient head space to prevent overflow and allow for expansion (about 2" for a one (1) gallon bottle). Do not fill containers of liquid to the top!
    3. Plastic milk jugs are not acceptable!!
  • Contents
    • Segregate solvent waste into three classes:
      • Halogenated (e.g., chloroform)
      • Water miscible, non-halogenated (e.g., acetone)
      • Non-water miscible, non-halogenated (e.g., hexane)
    • Do not mix organic wastes with inorganic wastes.
    • Segregate acids and bases; do not mix either with solvents.
    • Please call prior to mixing unusual wastes. Mixing may cause a magnitude increase in disposal costs or prevent any disposal of the material.
  • Labeling
    • Containers must be labeled HAZARDOUS WASTE. (This does not apply to unused material in its original container.)
    • Contents must be listed on label, including water. Estimate the quantities if several compounds are placed in the container.
    • Use conventional names for chemicals.
  • Unknowns - Unknown chemicals will not be accepted!!! Please call HMM to arrange for the testing of unknown chemicals.
  • General
    • Waste containers must be covered!
    • All wastes will not be accepted. A few compounds cannot be disposed of in a legal and/or safe manner.
    • Wastes must be stored in labs, not in hallways.

120.00 Costs

Generally there is no charge for hazardous waste disposal. It is an essential service that supports teaching, research, and operation of the university. However, chemical users have the responsibility to purchase and manage chemicals. They will be charged for unusually dangerous or expensive disposal problems resulting from unwarranted purchasing or excessive quantities of chemicals or poor management/storage of chemicals.

Examples:

  • Emergency tapping and venting of a large gas cylinder costs up to $15,000.
  • Peroxide forming compounds that cannot be shipped may require detonation.
  • Disposal of excessive amounts of highly reactive materials.
