1. (1) the Commonwealth will not alter or limit the rights and powers of the authority in any manner which would be inconsistent with the continued maintenance and operation of the project or the improvement thereof or which would be inconsistent with the due performance of agreements between the authority and any Federal agency; and
2. (2) the authority shall continue to have and may exercise all powers granted in this chapter as long as the powers are necessary or desirable for carrying out the purposes of this chapter and the purposes of the United States in the construction or improvement or enlargement of the project or portion thereof.
