Principal Investigators (PIs) must deactivate their CSUA under the following circumstances:

• Employment termination or departure from UAB
• Closure, expiration, or completion of a project
• Discontinuation of controlled substance use

To properly terminate a CSUA, the following steps must be completed:

1. Submit a deactivation request through the CSUA web application.
2. Return all controlled substances to Environmental Health & Safety (EH&S) following proper procedures. EH&S accepts returns every Tuesday and Thursday from 9:00 AM to 12:00 PM.
3. Return the CSUA binder with all original receipts, usage logs, and related documentation to EH&S.
4. Fill out the CSUA Termination Document — the form is available at this link.
5. Email a signed copy of the Termination Document to ehscs@uab.edu for official recordkeeping.

These actions are required to maintain compliance with UAB and DEA regulations.
