Release Points
You may view a full list of all Release Points associated with a facility from the Release Points accordion. The Release Point list includes all Fugitive and Stack release points associated with a single facility site. This section describes the process for viewing, adding, editing, or deleting Fugitive and Stack Release Points.

Release Point Audit Log
Provides information about changes that have occurred to the information about the Release Points associated with a facility site. It provides time-stamped values of data at the facility site, indicating who made the changes and which organization that person is associated. Please see the Release Point column for descriptions of the fields presented if needed.
Fugitive Release Point
Stack Release Point
Adding Release Point Records
If you have been authorized to update information for your agency, you will see an Add link in upper-right corner of the Release Point accordion.
Clicking on this link will open a blank form that will allow you to create a new Release Point for the facility record by populating the fields. The view changes based on the Release Point type selected.
Adding Fugitive Release Point Records
Selecting Fugitive 2D or Fugitive 3D as the Release Point Type will display the following fields, allowing you to create a new Fugitive Release Point for the facility record by populating those fields. Please note, Fugitive Area is no longer a selectable Release Point type, but is still viewable.
When creating a new Fugitive 2D Release Point, it will require Geographic Coordinate values for Midpoint 1 and Midpoint 2. As a reminder, unique latitude and longitude coordinates are required for each midpoint. For more information on midpoints, refer to the Release Points Geographic Coordinates page of the user guide.
Adding Stack Release Point Records
Selecting Downward-facing vent, Goose Neck, Horizontal, Low Flow Vent, Vertical, and Vertical with
Rain Cap will display the following fields, allowing you to create a new Stack Release Point for the
facility record by populating those fields. As a reminder, Stack Release Points will have one of the following:
1) Report Stack Diameter AND Stack Diameter Unit of Measure AND do not report Release Point Length
AND do not report Release Point Width.
OR
2) Report Release Point Length AND Release Point Width AND do not report Stack Diameter.
Editing Release Point Records
If you have been authorized to update information for your agency and the facility inventory window is open, you will see additional links available at the top right corner of the View Release Point page:
Clicking on the “Edit Release Point” link will open a form that will allow you to make changes to the information. Once all necessary fields have been populated, click on the “Save” button at the bottom of the form. Note that the fields have a red “starburst” indicator next to them, indicating that they are required fields. You will not be able to successfully save the information to the data base without values populated in these fields. EIS will evaluate the information provided. If there are any issues, errors will be displayed at the top of the form. If the Release Point, or specific fields of the Release Point, are protected/locked, you will not be able to edit it. Please contact an EPA Inventory Developer if you need assistance with any protected data fields or facility components.
Editing Fugitive Release Point Records
Fugitive Area is no longer a selectable Release Point type but is still viewable. You can edit a Fugitive Area to Fugitive 3D or 2D. If you change to Fugitive 2D from any other Release Point type, you will need to edit the Release Point Geographic Coordinates to include midpoint 1 and midpoint 2. As a reminder, unique latitude and longitude coordinates are required for each midpoint. This information can be found on the Release Points Geographic Coordinates page of the user guide.
Editing Stack Release Point Records
As a reminder, Stack Release Points will have 1 of the following scenarios for populating the data
fields associated with a Stack Release Point:
1) Report Stack Diameter AND Stack Diameter Unit of Measure AND do not report Release Point Length
AND do not report Release Point Width.
OR
2) Report Release Point Length AND Release Point Width AND do not report Stack Diameter.
Clicking on the “Undo” button will clear the form of all entries and leave you on the “Edit Release Point” page. Clicking on the “Cancel” button will not save any of the information that you have filled out, and you will be taken back to the Facility Site page.
Deleting Release Point Records
Clicking on the “Delete Release Point” link from the View Release Point page will allow you to delete a Release Point associated with the facility. You will receive a confirmation message asking if you’re sure you want to delete. Clicking OK will delete the Release Point from the facility site and return you to the Facility Site page. Clicking Cancel will not delete the Release Point, and you will remain on the View Release Point page. This applies to both Fugitive and Stack Release Points. If the Release Point, or specific fields of the Release Point, are protected/locked, you will not be able to edit it. Please contact an EPA Inventory Developer if you need assistance with any protected data fields or facility components.
