Specifically, Oklahoma will attempt to install a public compressed natural gas fueling station every 100 miles along all of the interstate highways in Oklahoma by 2015. By 2025, this number of stations will increase to one every 50 miles. The state's Department of Central Services is in charge of the program, and it's expected that public-private partnerships will be used to get the stations up and running. In April, Oklahoma became the fourth state where the only CNG-powered passenger car for private use in the U.S. went on sale. Thanks to Steve G. for the tip!
