If a chemical is newly added to the CCO list, what is the process?

• A. It would be added to the schedule with effective dates, transitional provisions, and update of license requirements.
• B. The chemical would be added to the schedule, with effective dates, transitional provisions, and update of license requirements.
• C. It would be removed from the CCO list entirely.
• D. No changes to licensing are required.

Answer: (B)

When a chemical is newly added to the CCO list, the regulatory action places it on the schedule of controlled substances with an effective date for when the controls begin. Transitional provisions explain how the change applies to existing licenses and activities, often providing a phased implementation or grace period. At the same time, licensing requirements are updated to reflect the new control status—so what licenses are needed, any new handling or reporting obligations, and the timelines for compliance are defined. This combination—adding the chemical to the schedule with effective dates, transitional provisions, and updated license requirements—is the proper, complete process. Removing it from the list or claiming no licensing changes are required would not fit how the CCO update works.
