This act shall become effective when the Governor by proclamation declares that sufficient funds are available to administer this act. For the purposes of this determination and then thereafter, in addition to any appropriations as are made to the agency, the Commonwealth is authorized to accept for the account of the agency grants-in-aid, donations and gifts of every manner and type from the Federal Government or from any other private or public corporation or person. Upon such declaration, such funds as have been collected shall immediately be paid to the treasurer of the agency, or if a treasurer has not been appointed, to such other person as the Governor may designate as acting treasurer.
