Emission Estimation Calculators - Booklet 1

These downloadable spreadsheet calculators were designed to assist with estimating the releases of National Pollutant Release Inventory (NPRI) substances from a variety of common operations or processes. The tools are focused on releases to air and are based primarily on default emission factors, however they can be adapted for the use of site-specific emission factors where these exist.

Since NPRI reporting thresholds are for the facility as a whole, the air releases calculated using these tools will need to be combined with releases from other sources and activities at the facility where applicable.

Fugitive Dust Emissions from Abrasive Blasting

Abrasive blasting involves blasting particles of sand or other material to clean or texturize a surface. The substances of concern in this activity are Criteria Air Contaminants (Part 4 Substances). Depending on the composition of the abrasive material and the material being abraded, other contaminants may also be released (ex. metals).

Download spreadsheet calculator: Abrasive Blasting Calculator (spreadsheet) [xls 62 KB] (4 Feb 2009)

Suggested estimation methodology: Emission Factor

Input Data

The emission factors for estimating total particulate matter emissions from abrasive blasting operation are available at three different wind speeds. Determine the annual mean wind speed for your area. Annual mean wind speed data is available at the Climate Data web site. The emission factors for PM10 (Particulate matter with a diameter less than or equal to 10 micrometres) and PM2.5 (Particulate matter with a diameter less than or equal to 2.5 micrometres.) do not vary with wind speed.

Use the emission factors to determine the annual emissions of each substance using the general equation for emissions estimation:

E = A x EF

Note on Emissions Factors

National Pollutant Release Inventory (NPRI) Basis of Estimate Code = E2 (Published Emission Factors).

The default emission factors are used in the table above, however if you have a site specific emission factor you would prefer to use you may enter it in the emission factor column. If you choose to insert your own emission factor ensure that the units have been converted accordingly. 

The emission factors used in this spreadsheet are based on uncontrolled emissions. If you are using an emission control device you will have to adjust the emissions calculated by this spreadsheet according to the following formula:

Controlled Emissions = Uncontrolled emission x ((100 - control efficiency)/100)

Fugitive Dust Emissions from Aggregate Handling

Aggregate handling includes material loading onto a storage pile and load-out from the pile onto a receiving surface. These drop operations may be batch or continuous. The substances of concern in this activity are Criteria Air Contaminants (Part 4 Substances). Note that emissions from wind erosion or from loader/truck traffic around the storage pile may need to be considered as well.

Suggested estimation methodology: Calculated Emission Factor

The general equation for emissions estimation is:

E = A x EF

where:

  • E = emissions
  • A = activity rate
  • EF = emission factor

Input Data and Release Calulations

The emission factors for estimating particulate emissions from a drop operation can be calculated as a function of the particle size, mean wind speed, and material moisture content. The methodology is explained in detail in chapter 13.2 of the U.S. Environmental Protection Agency (EPA) AP-42 document and summarized here.

  1. Determine M, the moisture content of the material (should be between 0.25 – 4.8%).

  2. Determine U, the annual mean wind speed for your area. Annual mean wind speed data is available at the Climate Data web site. You will need to convert the data to units of m/s.

  3. Calculate the emission factorsFootnote1 for Total Particulate Matter (TPM)Footnote*, Particulate Matter less than or equal to 10 micrometers (µm) (PM10)Footnote* and Particulate Matter less than or equal to 2.5 µm (PM2.5)Footnote* using these formulas:

    EFTPM = 0.74(0.0016)[(U/2.2)1.3 / (M/2)1.4]     (kilograms (kg)/tonne)
    EFPM10 = 0.35(0.0016)[(U/2.2)1.3 / (M/2)1.4]     (kg/tonne)
    EFPM2.5 = 0.053(0.0016)[(U/2.2)1.3/ (M/2)1.4]     (kg/tonne)

  4. Use the calculated emission factors to determine the annual emissions of each substance using the general equation for emissions estimation:

    E = A x EF

    where:
    • E = annual emissions (kg)
    • A = activity rate (tonnes of aggregate loaded per year).
    • EF = emission factor (kg/tonne)

    Do this calculation separately for each substance
    (i.e. ETPM = A x EFTPM, EPM10= A x EFPM10, and EPM2.5 = A x EFPM2.5)

Note on Emissions Factors

The default emission factors are used in the table above, however if you have a site specific emission factor you would prefer to use you may enter it in the emission factor column. If you choose to insert your own emission factor ensure that the units have been converted accordingly. 

Except where indicated, the emission factors used in this spreadsheet are based on uncontrolled emissions. If you are using an emission control device you will have to adjust the emissions calculated by this spreadsheet according to the following formula:

Note on Emissions Factors

The default emission factors are used in the table above, however if you have a site specific emission factor you would prefer to use you may enter it in the emission factor column.  If you choose to insert your own emission factor ensure that the units have been converted accordingly. 

The emission factors used in this spreadsheet are based on uncontrolled emissions.  If you are using an emission control device you will have to adjust the emissions calculated by this spreadsheet according to the following formula:

Controlled Emissions = Uncontrolled emission x ((100 - control efficiency)/100)

Feed Manufacturing

The substances of concern released from the production of animal feeds are Criteria Air Contaminants (CAC).

Download spreadsheet calculator: Feed Manufacturing [xls 74 kb] (4 Feb 2009)

Suggested estimation methodology: Emission Factor

The general equation for emissions estimation is:

E = A x EF

where:

  • E = emissions
  • A = activity rate
  • EF = emission factor

Input Data

The activity rate (A) is the number of tonnes of grain received or processed. There are individual emission factors for Total Particulate Matter (TPM), Particulate matter with a diameter less than or equal to 10 micrometres (µm) (PM10) and Particulate matter with a diameter less than or equal to 2.5 micrometres (PM2.5) for each of the processes. The total emissions for each substance will be the sum of the each of the emissions for each process.

Municipal Solid Waste Incineration in Newfoundland and Labrador – Conical Burners

Incineration of municipal solid waste (not wood waste) results in release of Mercury and its compounds (Part 1 Substances), hexachlorobenzene and dioxins/furans (Part 3 Substances) and Criteria Air Contaminants (Part 4 Substances). This waste disposal practice is believed to still exist in Newfoundland and Labrador.

Download spreadsheet calculator: Municipal Solid Waste Incineration in Newfoundland and Labrador – Conical Burners [xls 62 KB] (4 Feb 2009) (See also: Guidance on Reporting the Releases of NPRI Substances for Conical Burners in Newfoundland and Labrador.)

Suggested estimation methodology: Emission Factor

The equation for emissions estimation given the quantity of waste incinerated in tonnes is:

E = A x EF

where:

Inputs:
A = quantity of waste incinerated [tonnes];

If A is not known, it can be estimated using the following equation:

A = B x 0.811 x (C/365)Footnote*

where:

Input Data

A = Quantity of waste incinerated [tonnes per year]
B = Population served
C = Number of days of operation during the year

Note on Emission Factors

The default emission factors are used in the table above, however if you have a site specific emission factor you would prefer to use you may enter it in the emission factor column. If you choose to insert your own emission factor ensure that the units have been converted accordingly. 

The emission factors used in this spreadsheet are based on uncontrolled emissions. If you are using an emission control device you will have to adjust the emissions calculated by this spreadsheet according to the following formula:

Controlled Emissions = Uncontrolled emission x ((100 - control efficiency)/100)

Sulphur Dioxide (SO2) from Burning Sour Gas

This calculator is to assist with estimating the releases of sulphur dioxide from the burning of sour natural gas.  This calculation deals only with the conversion of hydrogen sulfide to sulphur dioxide. The following natural gas combustion calculators are available on the National Pollutant Release Inventory toolbox: external combustion boilers, internal combustion engines, and biogas flaring for natural gas with less than 80% methane.  Note that the combustion spreadsheets will also calculate a value for sulphur dioxide, however the value calculated here should be used instead as it will more accurately represent the actual release.

Download spreadsheet calculator: Sulphur Dioxide [xls 107kb] (4 Feb 2009)

Methodology used to develop calculations

Mass balance and stoichiometric information was used to develop the relationship between the concentration of hydrogen sulfide (H2S) in the natural gas being burned and the amount of sulphur dioxide (SO2) released to the air.

Input

A = activity (in this case the mass of H2S burned) [kilograms]
B = volume of H2S burned [cubic meters]
C = percentage of H2S in the gas by volume
D = destruction efficiency [%]
H = heating value [Giga Joules/cubic meter]
J = amount of sour gas burned [cubic meters]
K = amount of sour gas burned [Giga Joules]

If the amount of sour gas burned is not known in cubic meters you can convert the amount in Giga Joules using the following equation:

J = K/H

The conversion above is based on a default heating value (H) of 0.0386. If a site specific heating value is available please use that instead.

The volume of H2S burned is given by the equation:

B = J x C x D

The mass of H2S burned is then calculated by:

A = B x 1.44114915367

Equation to calculate the amount of Sulphur Dioxide Released

E = A x (64.0588/34.07588)/1000

where,

E = emission of sulphur dioxide (CAS 7446-09-5Footnote1) [tonnes]

Wood Working

The substances of concern for wood working are Criteria Air Contaminants and Speciated Volatile Organic Compounds (VOC).  These calculations can be broken down into three sections related to wood working processes: Painting Related, Natural Gas Consumption, and Sawdust Related.

To calculate the total emissions for all processes related for wood working sum the emissions for each substance across all processes where applicable.

Use Material Safety Data Sheet (MSDS) to determine what individual VOC species are released from various wood finishing processes.

Painting Related

Calculation for Part 4 VOC Releases

A mass balance approach is recommended. First calculate the mass of each product used. The mass can be calculated using the following formula:

M = (V x D)/1000

where:

Next, sum the mass of the volatile component of each product used.

E = (M x C)1 + (M x C)2 + …

Input

M = mass used [tonnes];
C = % volatile organic compound (VOC)

Note: C and D are found on the product MSDS sheet

Natural Gas Consumption

Input

N = amount of natural gas burned [million cubic meters]

If you know the amount of natural gas burned in Giga Joules the amount of natural gas burned in million cubic meters (m3) can be calculated by the following equation:

N = H/0.0386/1000000

where, H is the amount of natural gas burned in Giga Joules.

The emission factors used in this spreadsheet are based on uncontrolled emissions. If you are using an emission control device you will have to adjust the emissions calculated by this spreadsheet according to the following formula:

Controlled Emissions = Uncontrolled emission x ((100 - control efficiency)/100)
