Since legislation in 1991 channeled aviation
fuel taxes to "aviation purposes", the CDOT - Division of Aeronautics has reimbursed 65% of those taxes back into the airports - of - origin in the form of regular entitlement funds. At the same time, the Colorado Aeronautical Board began conducting the Colorado Discretionary Grant Program, utilizing the remaining 35% of
tax revenues to serve the maintenance, capital equipment, and developmental needs of Colorado's 74 public-use airports. In June 2003, new legislation was signed into law by Governor
Bill Owens. Senate Bill 49 continuously appropriates fuel tax dollars into the Colorado Aviation Fund. This legislation gives the Colorado Aeronautical Board increased flexibility when dispursing discretionary
grant dollars into the Colorado Airport System. ==References==
