Unit Emissions Process Component

An emissions process, characterized by an SCC, must be established for each activity that produces emissions at a unit at a facility site. Use the EmissionsProcess component to report the processes or activities that include: Identification; DeleteReportingPeriod; Reporting Period. The key element of the Emissions Process component is the SCC. Each facility site must have at least one unit and one emissions process defining the activity by SCC for that unit.

List of acceptable SCCs for point emissions. EPA has defined a list of SCCs which represent the expected processes and activities for point emissions. If you report SCCs that are not on the list of acceptable codes, they will be rejected. If you would like to request that an SCC be added for a particular point emissions process, submit a support request through the EIS Gateway. EPA will review and respond to this request within five business days.

Multiple processes for a unit. A unit may have more than one process, either historically (for different inventory cycles) or within the same inventory cycle. For example, a boiler could have two processes, one burning coal and one burning natural gas.

Completeness. There is no single list of processes and activities that would be applicable to a specific facility that can be used as a definitive check of submission completeness. Information may be provided as part of the quality assurance checks if expected SCCs or previously reported SCCs are not reported for a facility site.

Adding a new process to a unit. To add a new process to an emissions unit, provide the SCC, Program System Code, Process Identifier, Process Description (optional) Process Operating Status and Operating Status Year (if relevant), Release Point and an optional comment. The EIS will check to make sure that the SCC is not already in the EIS for that specific unit and, if not, will add the process to the EIS for that unit.

Updating process information. If you would like to update the information about a process that you know has already been reported for the unit, report the Process Identifier along with the SCC and all of the data elements in this component that you would like updated in the EIS. If you wish to completely change an SCC (such as moving from a generic SCC to a more detailed SCC) you will need to end the previous process by reporting a Process Operating Status and Process Operating Status Year for it, and then report the new process with the corrected SCC.

Impact of incomplete information or critical errors. If there are critical errors relating to the SCC, all data in the component will be rejected.
