FFIEC BSA/AML Examination Manual provides guidance for examiners when conducting BSA/AML examinations at financial institutions. The Manual has a dedicated section on sanctions, and refers to sanctions several time. Here are several examples:
P. 2 “While OFAC regulations are not part of the BSA, the core sections include overview and examination procedures for examining a bank’s policies, procedures, and processes for ensuring compliance with OFAC sanctions. As part of the scoping and planning procedures, examiners must review the bank’s OFAC risk assessment and independent testing to determine the extent to which a review of the bank’s OFAC compliance program should be conducted during the examination. Refer to core examination procedures, “Office of Foreign Assets Control,” page 152, for further guidance.
P.12 “OFAC requirements are separate and distinct from the BSA, but both OFAC and the BSA share a common national security goal. For this reason, many financial institutions view compliance with OFAC sanctions as related to BSA compliance obligations; supervisory examination for BSA compliance is logically connected to the examination of a financial institution’s compliance with OFAC sanctions. Refer to the core overview and examination procedures, “Office of Foreign Assets Control,” pages 142 and 152, respectively, for guidance. “
P. 21: “Higher-risk geographic locations can be either international or domestic. International higher-risk geographic locations generally include: 
Countries subject to OFAC sanctions, including state sponsors of terrorism.
Countries identified as supporting international terrorism under section 6(j) of the Export Administration Act of 1979, as determined by the Secretary of State.”
P. 111: Objective. Assess the bank’s compliance with statutory and regulatory requirements for correspondent accounts for foreign shell banks, foreign correspondent account record keeping, and due diligence programs to detect and report money laundering and suspicious activity. Assess the bank’s compliance with the Comprehensive Iran Sanctions, Accountability, and Divestment Act (CISADA), if applicable
P. 119: Objective. Assess the bank’s compliance with statutory and regulatory requirements for correspondent accounts for foreign shell banks, foreign correspondent account record keeping, and due diligence programs to detect and report money laundering and suspicious activity. Assess the bank’s compliance with the Comprehensive Iran Sanctions, Accountability, and Divestment Act (CISADA), if applicable.
P. 142 Objective. Assess the bank’s risk-based Office of Foreign Assets Control (OFAC) compliance program to evaluate whether it is appropriate for the bank’s OFAC risk, taking into consideration its products, services, customers, entities, transactions, and geographic locations.
