  design.
\2\ This does not replace the requirements for oxygen monitors that are
  required to use continuous emissions monitoring systems. These
  requirements apply to oxygen sensors that are continuous parameter
  monitors, such as those that monitor combustion zone oxygen
  concentration and regenerator exit oxygen concentration.
