DEQ Inspection Details



State and Federal regulation 40 CFR 262.34(c)(1), stipulates that a laboratory may accumulate as much as 55 gallons of hazardous chemical waste, if the lab meets the following conditions:

  1. Waste is accumulated in leak-proof containers that are chemically compatible with the contents.

  2. Waste containers are labeled with the words "Hazardous Waste" and a description of the contents.

  3. Containers of hazardous waste are kept tightly capped at all times, except when adding waste material. NOTE: Evaporation of hazardous chemical waste is not allowed.

  4. When a particular type of hazardous chemical is no longer being used in the lab, the accumulated waste is disposed of promptly. Note: DEQ will cite a lab for long-term storage of hazardous chemical waste in a laboratory satellite chemical waste accumulation area.


Violations of these regulations may result in fines. The University takes seriously the proper handling and disposal of hazardous chemical waste, and its responsibility to the community. As stated in the Roles and Responsibilities for Research, fines due to rule violations by faculty are the responsibility of the faculty or Department/ Division.

Additional Information
