Rule Summary

This rule controls hazardous air pollutants emitted from catalytic cracking units, catalytic reforming units, and sulfur recovery units at petroleum refineries. Recent amendments changed the affected source designations and added new compliance options for catalytic reforming units that use:

  • different types of emission control systems,
  • new monitoring alternatives for catalytic cracking units and catalytic reforming units, and
  • a new procedure for determining the metal or total chloride concentration on catalyst particles.
