The first three columns show the Emission Source ID (“FIN” in Texas), Emission Point
Number (“EPN”), and Control Identification Number (“CIN” for the control device, if one
exists) for each relationship. If new equipment relationships are created in your plant, they can
be added by clicking on the Insert icon and double clicking on the appropriate equipment items
in the lists that appear at the bottom of the screen. When adding new relationships that include a
control device, you will note that the list of CINs includes the associated FIN and EPN for each
device to assist users in selecting the correct control device. The equipment relationships
information is not reported to the agency. Unless updates are needed for other reasons such as
Data Pipeline usage or Ozone Season emission rate calculations (as explained below), users do
not need to update this information for their agency report.
The fourth column contains the Feeding CIN for each relationship, which denotes the Control
Device ID located immediately downstream from another Control Device. This information is
only
required for users that will use the Data Pipeline feature to copy emission rates from the
COMPASS-Calcs module into the EI emissions database. If there is no downstream Control
Device, this item may be left blank.
The fifth column contains the Percent Flow of Emissions from each FIN to each EPN/CIN
combination. This information is only required for users that will use the Data Pipeline feature to
copy emission rates from the COMPASS-Calcs module into the EI emissions database. Percent
flow from sources to points cannot be inferred from the agency data download, so it is blank
when users first review the Equipment Relationships detail screen. Clicking on the Set Defaults
icon will automatically insert the number “100%” for each relationship, but the user will need to
correct the default settings to better represent a single Facility ID related to multiple points, for
example. The percent flow for all equipment relationships that are connected in series is, by
