joint funding Sec. 406. Pursuant to regulations prescribed by the President, where funds are advanced for a single project by more than one Federal agency to an agency or organization assisted under this Act, any one Federal agency may be designated to act for all in administering the funds advanced. In such cases, a single non-Federal share requirement, may be established according to the proportion of funds advanced by each Federal agency, and any such agency may waive any technical grant or contract requirement (as defined by such regulations) which is inconsistent with the similar requirements of the administering agency or which the administering agency does not impose.
