The temperature adjustment factor will be applied only for emissions from those Source–
Point relationships that are indicated by the user for this function using features provided
in the Equipment Relationships menu. It is necessary to set up the system to apply
temperature adjustment factors based on the factor for a specific chemical, and the
equipment relationship, because the factor should not be applied for those emissions that
are captured in a vent control system or are otherwise unaffected by the ambient
temperature.
3. Also, from the Contaminant Maintenance main screen, users may revise the contaminant
category for a selected chemical, for example, from TSP to PM10. Such changes would
not be done often, but they may be needed at some future time. A dropdown list of
pollutant categories is provided. The most frequent category revision would be from an
unregulated category, (i.e., not a criteria pollutant such as VOC), to a regulated other
category. Categories are used to apply control efficiencies to emissions during the Data
Pipeline procedure as well as to calculate emission fees. Note that control efficiencies are
stored by category in the EI system.
4. By clicking on the Active radio button, contaminants can be revealed, or eliminated from
the display altogether, when new emissions are added to Source IDs and Points. An
Active/Inactive column is provided to indicate whether or not the contaminant should be
