2)         The duration of the excess emissions;

3)         The magnitude of excess emissions;

4)         The cause of the excess emissions, if known;

5)         Corrective actions and actions taken to lessen the emissions;

b)         For gaseous sulfur dioxide, percent oxygen, or carbon dioxide measurements, the averaging period used for data reporting shall correspond to the averaging period used to determine compliance with the emission limitation applicable to the source.  The report shall consist of emission averages in the units of the applicable limitation for each averaging period during which the limitation was exceeded.

c)         For opacity measurements, the report shall be based on six minute averages of opacity and contain.

1)         The percent opacity for each continuous opacity excess period; and

2)         The start and stop time in six minute increments of any opacity measurements in excess of the limitation.
