The calculations on this worksheet will help to estimate the volatile organic compound (VOC) from
a painting operation. If the VOCs do not exceed 5 tons per year, and you meet the other
requirements, you are eligible for the Small Source Exemption. After completing this worksheet,
enter the emission estimates in Section IV, Air Emission Information, of the Small Source
Registration Notice. Businesses exceeding the exemption limits that are listed in the Registration
Notice, are required to file a permit application, known as a Notice of Intent (NOI) with the Division
of Air Quality. If you need assistance filling out this form or information on the NOI, please contact
with the Small Business Assistance Program (SBAP) at the Division of Air Quality at 536-4000, if
you live in the Salt Lake City area or 1-800-270-4440, toll-free outside of the Salt Lake City area.

The estimating of emissions from a painting operation is a two step process. First you
estimate the volatile organic compound (VOC) emission and second the hazardous air
pollutant emissions. The second calculation requires the use the fact sheet “How to
Estimate Your Hazardous Air Pollutant Emissions.” Typically 30-50% of volatile
organic compounds may be hazardous air pollutants, so do not forget to estimate the
hazardous air pollutants in the paints, solvents and other chemicals used at the business.
The VOCs can be estimated using the procedure below:
Step 1 Estimate the total gallons of products (use Column A as a guideline) that you use
on an annual basis. This can be estimated by recording what you use in an
average month and then multiplying by 12 to convert to annual basis. Enter
number in Column C.
Step 2 Multiply the gallons per year in Column C by the pounds of VOCs per gallon that
is given in Column B. Column B contains typical VOC values for these products.
You can use these values or correct the value to match the actual products you
use for a more accurate estimate of VOC’s per year, D=BxC. Enter the number
in Column D. The VOC content per gallon of coating can be obtained from your
Material Safety Data Sheets (MSDS), if the content is not listed in Column B.
Step 3 Add the numbers in column D and enter total in Box X. Divide by 2,000 to
convert pounds to tons. Y = X / 2000, Enter the number in Box Y.
If the total in Box Y does not exceed 5 tons per year, and you meet the other requirements,
you can use the Small Source Registration Notice. If the number exceeds 5 tons per year,
you should review the quantities and decide if the numbers are good estimates of the
usage at your facility. If the total still exceeds the small source registration quantities, you
might consider finding new paints with lower VOC contents. Contact your supplier and ask
for substitutes products with lower VOC contents. Note: Compliance inspectors can ask
for documentation of all information of on these forms. If after reviewing the numbers the
total still exceeds 5 tons per year you will need an air permit. Contact the Small Business
Assistance Program for the additional information you will need to submit to receive an air
permit.
