The Centre Area Transportation Authority (CATA) operates in Centre County, Pennsylvania, serving the State College region. This system has made a point of making its fleet 100% CNG, with it's last diesel buses being retired the summer of 2009. Part of the reason that this is a 100% CNG fleet is because the State College region is rich in natural gas.
