"Movement area" is defined in the Pilot/Controller Glossary. At Renton,
Washington, the whole airport is non-movement except for the runway and
the runup areas. Ground Control will answer if you call, but no calls are
expected. Conflicts between airplanes and vehicles are worked out between
the participants with no input from the tower cab.


FAR 91.129 states "No person may, at any airport with an operating control
tower, operate an aircraft on a runway or taxiway, or take off or land an
aircraft, unless an appropriate clearance is received from ATC." There is
no exception for taxiways designated as nonmovement area.
