Louisiana Sen. David Vitter, who had been holding up Gina McCarthy’s nomination in committee, announced on Tuesday that he won’t support a filibuster against her confirmation on the senate floor. Vitter and other members of the Committee on Environment and Public Works had indicated their dissatisfaction with EPA’s responses to five transparency questions in May. Acting EPA Administrator Bob Perciasepe responded on Tuesday discussing the agreement reached with Vitter and the fulfillment of some transparency requests. (Hence Vitter’s announcement that McCarthy’s nomination should go to the floor.) Of importance is that EPA has established two websites, one, which will contain all petitions for rulemakings and the other, all notices of intent to sue. The web addresses can be found at http://www2.epa.gov/aboutepa/petitions-rulemaking and http://www.epa.gov/ogc/noi.html.
