The University of Colorado Boulder has adopted an open access policy.
Here's an excerpt from the announcement:
"We are delighted that the Chancellor's Executive Committee has approved an Open Access policy for the campus that was endorsed by the Boulder Faculty Assembly, the Council of Deans, and the Office of the Provost and Executive Vice Chancellor," said University of Colorado Boulder Chancellor Philip P. DiStefano. "CU-Boulder proudly joins the ranks of other campuses in higher education that have created such policies in the interest of openly sharing their published intellectual assets."
