I know reg cc is one of those regulations that requires annual training. Can someone tell me where in the reg or commentary it states this?

Reg CC relates to the Expedited Funds Availability Act. The Act is found in Title VI of the Competitive Quality Banking Act of 1987. Section 607 (e) states:
"Each depository institution shall (1) take such actions as may be necessary fully to inform each employee (who performs duties subject to the requirements of this title) of the requirements of this title, and (2) establish and maintain procedures reasonably designed to ensure and monitor eemployee compliance with such requirements."

Thanks for your help

Here is the text of section 229.19(f) of Regulation CC.

"(f) Employee training and compliance. Each bank shall establish procedures to ensure that the bank complies with the requirements of this subpart, and shall provide each employee who performs duties subject to the requirements of this subpart with a statement of the procedures applicable to that employee."

Here's the Official Staff Commentary to this section:

"F. 229.19(f) Employee training and compliance.
1. The EFA Act requires banks to take such actions as may be necessary to inform fully each employee that performs duties subject to the EFA Act of the requirements of the EFA Act, and to establish and maintain procedures reasonably designed to assure and monitor employee compliance with such requirements.
2. This paragraph requires a bank to establish procedures to ensure compliance with these requirements and provide these procedures to the employees responsible for carrying them out."

The word "annual" is not used. This may be an industry best practice to conduct "annual training."
