Step 1 does not apply to units monitored by CEMS. If you are reporting for a unit monitored by CEMS, please skip to Step 2a.
The annual CO2 emission rate emissions from coke calcining operations is required. To calculate this value download the spreadsheet by clicking the link titled "Use Y-13 spreadsheet to calculate." Fill in the spreadsheet using the instructions in the spreadsheet. After completing each respective spreadsheet, copy the value of CO2 calculated by the spreadsheet to this page in the box next to "Annual CO2 emission rate from this coke calcining unit (metric tons)."

- Method used to measure the annual carbon content of green coke fed to the unit:
- ASTM D3176-89-Reapproved 2002
- ASTM D5291-02-Reapproved 2007
- ASTM D5373-08
- Other (specify)
- Method used to measure the annual carbon content of marketable coke produced:
- ASTM D3176-89-Reapproved 2002
- ASTM D5291-02-Reapproved 2007
- ASTM D5373-08.
- Other (specify)
- Description of coke dust recycling for the unit:
- All dust is recycled
- A portion of the dust is recycled
- None of the dust is recycled

The annual CH4 and N2O emission rates emissions from coke calcining operations are required. To calculate these values download the appropriate spreadsheet by clicking the link titled "Use Y-9 spreadsheet to calculate" for CH4 or "Use Y-10 spreadsheet to calculate" for N2O. Fill in the spreadsheet using the instructions in the spreadsheet. After completing each respective spreadsheet, copy the value of CH4 and N2O calculated by the spreadsheet to this page in the box next to "Annual CH4 emission rate from asphalt blowing from this coke calcining unit (metric tons)" or "Annual N2O emission rate from asphalt blowing from this coke calcining unit (metric tons)," as appropriate.

The annual CH4 and N2O emission rates emissions from coke calcining operations are required. Enter the value of CH4 and N2O in this page in the box next to "Annual CH4 emission rate from this coke calcining unit (metric tons)" or "Annual N2O emission rate from this coke calcining unit (metric tons)," as appropriate.
Both CH4 and N2O emission rates emissions include the basis for the emission factor:
- Weekly or more frequent measurements
- Periodic (less frequent than weekly) measurements
- Average of multiple source tests
- One-time source test
- Other (specify)
Step 3: Save Your Data
When you have finished entering emission results, click SAVE.
After you save the data on this page, the next time you open the page, the calculators on the top of the page will display the CO2, CH4 and N2O emissions, rounded to the nearest 0.1, 0.01, and 0.001 of a metric ton, respectively. The value displayed is for informational purposes only.
