The Social Services Administration is established and continued as the same State Department of Social Services hitherto existing. The Social Services Administration shall be part of the Department of Human Resources. The Social Services Administration shall have the powers, duties, responsibilities and functions provided in the laws of this State for the State Department of Social Services, except for the powers, duties, responsibilities, and functions that pertain to the income maintenance programs that are assigned to the Family Investment Administration under Article 88A, § 1A of the Annotated Code. Any reference to the State Department of Social Services or the State Department of Public Welfare in this Code, in any other laws of this State, or in ordinances, resolutions, rules, regulations, legal actions, directives or documents shall be deemed to mean the Social Services Administration if, and to the extent that, the reference involves social service programs. However, if, and to the extent, the reference involves income maintenance programs that are assigned to the Family Investment Administration under Article 88A, § 1A of the Code, the reference shall be deemed to mean the Family Investment Administration. From and after September 1, 1970, all rights, powers, duties, obligations, and functions heretofore conferred upon or exercised by the State Department of Social Services shall be transferred to and be exercised by the Social Services Administration or the Family Investment Administration, subject to the authority of the Secretary of Human Resources as set forth in §§ 6-102, 6-103, and 6-104 of this article or elsewhere in this Code.
