In summary, these comments describe a new technology for CNG (involving storage of gas at lower pressures using activated carbon) and recommend three changes to level the playing field for natural gas transportation fuels: (1) eliminate the 2-to-l fueling requirement for dual-fueled vehicles; (2) eliminate the related the related drive-to-empty requirement; and (3) restore the 0.15 multiplier for natural gas vehicles. Again, I appreciate your consideration and would be happy to answer any questions you or your staff may have. Regards, Charles Charles L. Ingebretson] Partner | AJW, Inc. :... Ex.""
