 A group of 18 states, joined by the District of Columbia and six municipalities, have moved to intervene on behalf of EPA, along with a number of other parties, including owners, developers, and operators of power plants; the municipally-owned utilities of Austin and Seattle; and Pacific Gas and Electric Company, a utility that provides electricity and gas to northern and central California. In addition, two former EPA administrators—William D. Ruckelshaus, EPA’s first and fifth administrator, and William K. Reilly, who led the agency during President George H.W. Bush’s administration—sought to participate on EPA’s behalf as amici curiae. Additional parties have also asked to intervene on behalf of the petitioners challenging the Clean Power Plan rule.
