On May 24, the Senate Armed Services Committee passed a Department of Defense authorization amendment from Sen. James Inhofe (R-OK) restricting the amount of money the Pentagon can spend on biofuels on a per-gallon-basis, echoing previously passed House measures. Another amendment would limit the Navy's ability to participate in an interagency agreement that includes a commitment to invest $510 million in drop-in biofuels. The legislation, not yet publicly available, is expected to reach the Senate floor in July.
