    Wet scrubber means an air pollution control device that removes
particulate matter and acid gases from the waste gas stream of
stationary sources. The pollutants are removed primarily through the
impaction, diffusion, interception and/or absorption of the pollutant
onto droplets of liquid. Wet scrubbers include venturi scrubbers,
marble bed scrubbers, or impingement scrubbers. For purposes of this
subpart, wet scrubbers do not include dynamic wet scrubbers.
