Calculate Emissions
Use this tool to calculate emissions from engines using multiple
fuels to see if you need an APCD permit.
Please check only one of the first three statements below. Also, check
"boilers" if you have any. Then click on Start to calculate
emissions.
Do you have
fuel data for each engine at your source?
Do you have fuel use data for any of your engines?
Do you only have
annual operating hours for each engine?
I have boilers
Note: Do NOT include engines used to propel vehicles, such as tractors in
the following tables. If you have
Only boilers, contact the APCD for
assistance.
If you do not have annual fuel use data and do not know operation hours
for any of your engines and your entire stationary source is more than 900
acres, then please contact the APCD for further guidance.
