The Point Emissions component hierarchy displayed below shows the relational hierarchy of the components within the CERS_v2 Point Emissions structure. Click on the green component blocks below to navigate to the user guide documentation for that individual component. Please note that although Facility Inventory components (FacilitySite, EmissionsUnit, and UnitEmissionsProcess) are needed in order to properly identify the processes to associate the emissions, you may not create or change information about the facility inventory from a Point data category submission. You must submit the FacilityInventory submission separately.
