* Pounds per hour for existing facility taken from table 5.1-3 of air quality analysis.

**Pounds per hour for two turbines of proposed facility taken from table 5.1-5 of air quality analysis.

Note. The emissions per hour for the proposed facility are ONLY for the two turbines and do not include start up emissions.

Much higher per-hour emission factors are in Table 5.1-7, but I do not know how they derived these and they seem too high.
