The emissions that you enter in the process vent unit page should be zero, because those emissions should be included in the facility-level emissions reported for delayed coking units. Be sure to select "delayed coking" for the "operation type" on the process vent information page. Click this link to access instructions for entering Subpart Y Process Vents Unit Information
