Subpart Y requires you to report the following data for each delayed coking unit at your facility:
- A unique name or identifier, plus optional description. See also About Unique Unit Names
- Method used to calculate the CH4 emissions:
- 98.253(\i)(1) - Equation Y-18 and Y-19, or
- 98.253(\i)(2) - Equation Y-18
| Info |
|---|
Note: If you select 98.253(i)(1) - Equation Y-18 and Y-19, you must also add the process vent associated with this delayed coking unit to the process vent section on the Subpart Overview page. 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 |
When you are finished entering the required information, click SAVE.
