Democrats in the Oregon Legislature made last-minute changes to their controversial climate change policy Thursday before voting it out of committee along party lines amid strenuous objections from Republicans in the Senate.  Senate Bill 1530 now moves to the Joint Ways and Means committee.  Thursday’s hearing before the Senate Committee on Environment and Natural Resources was contentious as Democrats delivered a 177-page amendment to the bill late Wednesday, and Republican 30th District Senator and committee member Lynn Findley said with its complexity more time was needed to examine it.  The House Committee on Energy and Environment voted on a different cap-and-trade bill earlier Thursday that Democrats can keep a backup to the Senate version alive in case they need it later in the session.  But Republicans on the House committee registered their objection by stepping out of the hearing room before the vote.
