Potential To Emit Calculator for Concrete Batch Plants

7/2/2014

This spreadsheet helps estimate a facility's potential to emit. 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.

Uncontrolled PM/PM10 (tons/yr) = Maximum Throughput Rate (tons/hr) x Emission Factor (lbs/ton) x 8,760 hr/yr x 

Controlled Emissions PM/PM10

The source will use periodic sweeping to control the fugitive dust emissions. 

Control Efficiency From Watering (%): 50%

 [EPA will assume 50% control from following fugitive dust control plan for roadways.]

PM Emissions After Control (tons/yr) = PTE Before Control (tons/yr) x (1 - Control Efficiency From Sweeping/W

PM10 Emissions After Control (tons/yr) = PTE Before Control (tons/yr) x (1 - Control Efficiency From Sweeping/W
