In 2008, Congress enhanced the commission's duties and powers. Section 332 of the Consolidated Natural Resources Act of 2008 (P.L. 110-229; May 8, 2008) more clearly defined the commission's ability to solicit donations and contract for specialized services, and permitted it to do so outside of existing federal law. The commission was also empowered to seek the assistance of any federal agency (so long as it paid for that assistance), enter into cooperative agreements with the same, and to procure administrative and support services from the General Services Administration. A commission staff was also established. An executive director was required to be employed, and the commission was authorized to hire staff (including an architect, and no more than three senior staff) and accept volunteers. Commissioners (and staff and volunteers) were now reimbursed for their reasonable travel expenses. Most importantly, an unlimited amount of money was authorized (but not actually appropriated) to carry out the commission's duties and to design and construct the memorial.
