One reason would be the growth they achieved from 2005 to 2008. The majority of it being before there was an oil crisis. The future looks to have even more demand on CNG as stated in the 10k :)

from the 10K: The number of fueling stations we served grew from 147 at December 31, 2004 to 176 at December 31, 2008 (a 19.7% increase). Included in this number are all of the CNG and LNG fueling stations we own, maintain or have a fueling supply contract with. The amount of CNG and LNG gasoline gallon equivalents we delivered from 2005 to 2008 increased by 29.4%.
