Paterson quickly signed five pieces of legislation on his first day in office: to add the New York State Department of Labor to the New York City Transit Track Safety Task Force; to eliminate a law that discouraged employers from holding blood drives; to change the way in which members are appointed to a state health and research board; to restore eligibility caps to certain senior employment programs; and to grant tax exemptions to several local development corporations in New York State. Paterson appointed Christopher O. Ward to be Executive Director of the Port Authority on May 22, 2008. Ward was successful in turning around construction at World Trade Center Site, and started the process of turning Farley Post Office into Moynihan Station.""
