The Office of Personnel Management may determine that the provisions of section 7(k) of the Act apply to certain categories of law enforcement employees based on appropriate factors, such as the type of premium payments they receive (see §§ 551.501(a)(1) and (5) and 551.541).

Law enforcement activities. Law enforcement activities involve work directly and primarily concerned with:

Patrol and control functions that include patrolling an area to enforce law and order and to protect the lives, property, and civil rights of individuals through the prevention and detection of criminal acts; responding to complaints, violations, accidents, and emergencies; investigating for clues at the scene of a crime, interviewing witnesses, and evaluating evidence to locate suspects; and apprehending and arresting persons suspected of, or wanted for, criminal violations under a statutorily prescribed arrest authority;

Executing the orders of a Federal court, including serving civil writs and criminal warrants issued by Federal courts; tracing and arresting persons wanted by warrants; and seizing and disposing of property under court orders;

Planning and conducting investigations relating to alleged or suspected violations of criminal laws, including the arrest of suspected or wanted persons under a statutorily prescribed arrest authority;

Security functions in a correctional institution involving direct custody and safeguarding of inmates charged with or convicted of violations of criminal laws; or

Rescue and ambulance functions that provide the primary (i.e., the first called) service in connection with law enforcement activities described above.

Engaged in law enforcement activities. The following employees are engaged in law enforcement activities for the purpose of determining possible application of section 7(k) of the Act as provided for in § 551.501(a)(1) and (5) and § 551.541:

Employees in positions properly classified in the Police series, and employees in positions that would be otherwise classifiable in that series if covered by classification criteria of chapter 51 of title 5, U.S. Code;

Employees whose primary duties involve patrol and control functions performed for the purpose of detecting and apprehending persons suspected of violating criminal laws;

Employees in positions properly classified in the U.S. Marshal series;

Employees in positions properly classified in the Criminal Investigating series, and other employees performing criminal investigation as their primary duty, except as provided for in § 551.213 (Exemption of employees receiving availability pay);

Employees in positions properly classified in the Correctional Officer series, Guard series, or other series, whose primary duty is to maintain custody of inmates of a correctional institution; and

Employees on rescue and ambulance crews that provide the primary service in connection with law enforcement functions, provided that crew members have received intensive training in specialized rescue and first aid procedures applicable to law enforcement emergencies (e.g., gunshot wounds, riot and accident victims) and the crew responds to actual or potential law enforcement emergencies on a regular and recurring basis.

Not engaged in law enforcement activities. The following employees are not engaged in law enforcement activities for the purpose of pay under section 7(k) of the Act as provided for in §§ 551.501(a)(1) and (5) and 551.541:

Employees whose primary duties concern the protection of Government property from hazards such as sabotage, espionage, theft, fire, or accidental or willful damage and in so doing, control the movement of persons and protect the lives and property of persons on Government property (e.g., guards or other employees performing similar functions);

Employees who perform work concerned with the determination of the applicability of or compliance with laws and regulations when the duties primarily involve:

Examining or inspecting products, premises, property, or papers of persons or firms to enforce or obtain compliance with laws and regulations (e.g., immigration and customs examining or inspecting; mine safety and health examining or inspecting; alcohol, tobacco and firearms examining or inspecting; plant protection and quarantine examining or inspecting); or

Planning and conducting investigations covering the character, practices, suitability or qualifications of persons or organizations seeking, claiming or receiving Federal benefits, permits, or employment (e.g., general investigations work);

Employees who work within correctional institutions but who do not have direct custody and safeguarding of inmates as their primary duty; and

Members of rescue or ambulance crews that provide those services in connection with law enforcement activities only in unusual situations (e.g., when the primary crews are unavailable or when an emergency situation requires more crews than can be provided by the primary service).
