2)         The basis by which emissions were determined;

3)         The expected consistency and reliability of operation of the emission unit;

4)         The operating schedule or intended use of the emission unit;

5)         The air pollution control equipment or control measures applied to the emission unit;

6)         The nature of applicable requirements;

7)         The environmental impact of such emission unit; and
