Pub. L. 90-110, tit. VIII, sec. 803

Sec. 803. Any of the amounts named in titles I, II, III, and IV of this Act, may, in the discretion of the Secretary concerned, be increased by 5 per centum for projects inside the United States (other than Alaska) and by 10 per centum for projects outside the United States or in Alaska, if he determines in the case of any particular project that such increase (1) is required for the sole purpose of meeting unusual variations in cost arising in connection with that project, and (2) could not have been reasonably anticipated at the time such project was submitted to the Congress. However, the total costs of all projects in each such title may not be more than the total amount authorized to be appropriated for projects in that title.
