It is provided for the convenience of the permitted community. Emission factor sources are subject to revision or correction. It is the permittee's responsibility to determine their emissions. The permittee should consult with the reviewing authority to determine the appropriateness of this calculator for its source. Enter the facility's information below in the cells with **red text**

. Write the letter "Y" or "N" next to each fuel type to indicate that the facility does or does not burn that type of fuel. **Enter the maximum capacity information for the equipment at your concrete batch mix operation (lines 14 - 24) OR**  **Enter the maximum number of yards of concrete your plant can deliver (maximum production capacity) in one year (line 26).** The potential emissions of criteria pollutants and hazardous air pollutants for the facility will be displayed under the "Output" tab. This calculator does not calculate non-emergency engines. Contact your reviewing authority if you use non-emergency engines to power your operations.

**Facility Profile**

If the throughput capacity of a piece of equipment limits (or bottlenecks) the maximum throughput of other equipment, then input the bottlenecked capacity of that other equipment, but only if it impacts output of product. If you operate multiple facilities of the same type (more than one aggregate conveyor, more than one generator), enter the total rated capacity.
