Just before ending the five-hour long investigation into the U.S Environmental Protection Agency\u2019s waiver denial, Senator Barbara Boxer (D-CA) announced she was introducing a bill to avert similar EPA waiver disapprovals. The legislation directs the EPA administrator to grant California\u2019s request for the waiver and allow the state to implement its greenhouse gas emissions standards for vehicles. It also permits other states to adopt California\u2019s emissions standards. \u201cI will use every available tool to ensure that California and the nation are able to reduce the pollution that causes global warming,\u201d Boxer said January 24. \u201cOne of those tools is legislation that essentially overturns Mr. Johnson\u2019s actions.\u201d Boxer introduced similar legislation last year, but it never got off the ground. Cosponsors of this week\u2019s bill include Senator Dianne Feinstein (D-CA), 12 other Democratic senators, as well as Senators Joe Lieberman (I-CT) and Susan Collins (R-ME).
