4. CO2 is calculated at Natural Gas @ 8270 hr/yr and backup diesel at 500 hr/yr, all others are NG @8760 plus backup diesel at 500 hr/yr. 2. Assume PM emissions are equal to PM10 emissions. 3. Results are already added to Natural Gas PTE. 3. If in extreme or severe ozone nonattainment, NOx emission factor reflects NOx limit in general permit. Directions

For example, requirements on limit the amount of sulfur in diesel (or #2 oil) for both transportation use as well as for stationary use in boilers. Common non-standard fuels such as Wood, off-gasses from digesters and waste oil have their own specific regulations and the variation in the fuel supply requires specific site analyses.
