42 U.S. Code § 12655n - Federal and State employee status
Participants and crew leaders shall be responsible to, or be the responsibility of, the program agency administering the program on which such participants, crew leaders, and volunteers work.
Except as otherwise provided in this subsection, a participant or crew leader in a program that receives assistance under this division shall not be considered a Federal employee and shall not be subject to the provisions of law relating to Federal employment.
For purposes of chapter 171 of title 28, relating to tort claims procedure, a participant or crew leaders assigned to a youth corps program for which a grant has been made to the Secretary of Agriculture, Secretary of the Interior, or the Director of ACTION, shall be considered an employee of the United States within the meaning of the term “employee of the government” as defined in section 2671 of such title.
For purposes of section 5911 of title 5, relating to allowances for quarters, a participant or crew leader shall be considered an employee of the United States within the meaning of the term “employee” as defined in paragraph (3) of subsection (a) of such section.
Contract authority under this division shall be subject to the availability of appropriations. Assistance made available under this division shall only be used for activities that are in addition to those which would otherwise be carried out in the area in the absence of such funds.
 So in original. Probably should be “provisions”.
For transfer of functions of Director of ACTION Agency (including all related functions of any officer or employee of ACTION Agency) to Corporation for National and Community Service, and effective date of such transfer, see section 203(c), (d) of Pub. L. 103–82, set out as a note under section 12651 of this title.
