(a) There was an equipment malfunction beyond the reasonable control of the owner or operator;

(b) The excess emissions could not have been avoided by better operation, maintenance or improved design of the malfunctioning component;

(c) To the maximum extent practicable, the source maintained and operated the air pollution control equipment and process equipment in a manner consistent with good practice for minimizing emissions, including minimizing any bypass emissions;

(d) Any necessary repairs were made as quickly as practicable, using off-shift labor and overtime as needed and as possible;

(e) All practicable steps were taken to minimize the potential impact of the excess emissions on ambient air quality; and

(f) The excess emissions are not part of a recurring pattern that may have been caused by inadequate operation or maintenance, or inadequate design of the malfunctioning component.
