Hazardous Waste Determination Form

A HWDF must be filled out for any spent waste (not in original container) with more than one chemical component (excluding water). For example, 35% HCl 65% water would not require a HWDF but 35% HCl 45% water 20% EtOH would require a HWDF. 

Every chemical in the waste should be included on the HWDF with a percent (%) concentration so that the total concentration adds up to 100%. This includes all nonhazardous components such as water, PBS, etc. If the exact percentage is not known, an approximate percentage is acceptable.

The constituents of the waste are whatever chemicals are going to the waste stream and should be the same as the chemicals on the waste label. If unlabeled, unknown waste is found, please submit a chemical pickup request as soon as possible so that EHS can handle the waste.

If you are unsure of the characteristics of your waste, leave that field blank and EHS staff will determine the characteristics.

No, EHS will conduct any characteristic testing if it is needed.

You will get a confirmation email that it has been submitted. Once EHS has looked over the form and made a determination, you will get an emailed copy of the completed form including the designation.

The confirmation and determination emails may have been sent to your junk or spam folders. Please check there. The email sender may appear as "safe-no-reply@umaryland.edu" with subject line "A new Hazardous Waste Determination Form has been submitted to EHS" after you submit. After someone from EHS has reviewed your form, you will receive another email with subject line "Hazardous Waste Determination Form- EHS Evaluation Complete." 

If you still can't find the emails, you may have mistyped some information or there may be a technical error. Reach out to the Chemical Hygiene Officer or Environmental Programs Manager above. 

Keep this information on record. This form should be kept on file for at least three years after the final generation of the waste. It does not need to be printed out, but should be easily accessible on the computer.

No. All chemical waste needs to be processed through EHS regardless of status.

Each time a new waste stream is created, or an existing waste stream is changed.

A new HWDF should be submitted with updated information. The determination may change.
