Utah Division of Air Quality Revised: 6/21/06
Attachment A: Small Source Exemption Registration Instructions

General Instructions:

Estimate your emissions using the appropriate emission worksheet, see Attachment D, E, and F. These
worksheets layout calculations for equipment that a business would typically use for each category. If any
of the worksheets have equipment not used by the business then write in: not applicable. When estimating
emissions from painting processes the calculation is a two step process: the first estimates the volatile
organic compounds (VOCs) and the second determines the hazardous air pollutants in the VOCs.

Remember the calculated emissions must be less than 5 tons per year per air contaminant of any of the
following air contaminants: sulfur dioxide (SO2), carbon monoxide (CO), nitrogen oxides (NOx), particulate
matter (PM10), ozone (O3), or volatile organic compounds (VOCs). Hazardous air pollutant emissions must
be less than 500 pounds per year of any one hazardous air pollutant and less than 2000 pounds per
year of any combination of hazardous air pollutants. And actual emissions are less than 500 pounds
per year of any air contaminant not listed above and less than 2000 pounds per year of any combination of
air contaminants not listed in above.

Businesses are not required to submit a Registration Notice. There is a minimum fee to process the
registration notice. Send it to Permits, Division of Air Quality, POB 144820, Salt Lake City, UT
84114.

Lines 1 thru 5: Fill in the name, address, phone number, and fax number of the business applying for
the permit exemption. Fill in the street address if different from item 1 and directions to business if
needed for remote locations, i.e., five miles south on highway 101, turn left at farmhouse, go 1.5
miles.

Line 6: Fill in the date when the business was first operational.

Line 7: Describe the process that emits air pollutants to the outside air. This includes the product being
processed (what is it), type of process (what=s being done to it), product flow through the system (how
it is being done) and the equipment used to perform the process. It might read something like this:

We are spray painting whizmos in a 6 foot deep updraft booth with a fabric filter using 1 hand-held
HVLP spray gun. A batch of 4 whizmos each measuring 12 by 27 inches are put in the booth at a
time. After spraying is complete, the technician allows the whizmos to dry for 3 minutes before
removing. A new batch is brought into the booth approximately every 11 minutes. Whizmos are
cleaned with Product Green prior to painting.

Line 8: List any pollution control equipment at the site. Examples of a pollution control devices are
bag houses or paint booths.

Line 9: Typical operating schedule would be 8am to 5pm, Monday thru Friday.

Line 10: Provide an estimate of actual emissions from all emission points in pounds per year (lbs/year) of
the following criteria pollutants: sulfur dioxide (SO2), carbon monoxide (CO), nitrogen oxides (NOx),
particulate matter (PM10), ozone (O3), and volatile organic compounds (VOCs). The control efficiency
of air pollution control equipment should be taken into account when estimating actual emissions. The
Division of Air Quality has developed worksheets for some types of processes to help estimate your
actual emissions. A list of the emission worksheets is included on page 2 of these instructions.
Include information on any other air contaminants, such as hazardous air pollutants, that may be of
concern. Contact the Division’s Small Business Assistance Program (SBAP) at [phone] or
[phone] or the Division’s New Source Review section at [phone] for more information.

Attachment A: Small Source Exemption Registration Instructions - Continued

Provide an estimate of actual emissions from all emission points in pounds per year (lbs/yr) of
hazardous air pollutants (HAPs) using the ranges provided. Actual emissions should be based on true
operating hours taking into consideration seasonal fluctuations. Indicate which HAPs are emitted by
your business by checking the box(es) in Attachment C. A fact sheet, How to Estimate Your
Hazardous Air Pollutants Emissions, is available through the Division’s Small Business Assistance
Program (SBAP) at [phone] or [phone].

Line 11: Check the boxes and Sign the form.

Definitions:

Hazardous Air Pollutant (HAP): HAPs are chemicals that cause serious health and environmental
effects. Health effects include cancer, birth defects, and nervous system problems. HAPs are released by
sources, such as chemical plants, dry cleaners, printing plants, and motor vehicles (cars, trucks, buses,
etc.). Refer to Attachment C for a list of the 187 HAPs and how to estimate HAP emissions.

For a more comprehensive list of definitions, see R307-101-2, Utah Air Conservation Rules.

Note: The rule on this page describes the
requirements of one permitting option. This rule
exempts you from the permitting process, not
the rules that apply to your business. There are
probably other air quality rules applicable to
your business.

R307-401-9. Small Source Exemption.
(1) A small stationary source is exempted
from the requirement to obtain an approval order in
R307-401-5 through 8 if the following conditions are
met.
(a) its actual emissions are less than 5 tons
per year per air contaminant of any of the following
air contaminants: sulfur dioxide, carbon monoxide,
nitrogen oxides, PM10, ozone, or volatile organic
compounds;
(b) its actual emissions are less than 500
pounds per year of any hazardous air pollutant and
less than 2000 pounds per year of any combination
of hazardous air pollutants;
(c) its actual emissions are less than 500
pounds per year of any air contaminant not listed in
(a)( or (b) above and less than 2000 pounds per year
of any combination of air contaminants not listed in
(a) or (b) above.
(d) Air contaminants that are drawn from the
environment through equipment in intake air and then
are released back to the environment without
chemical change, as well as carbon dioxide, nitrogen,
oxygen, argon, neon, helium, krypton, xenon should
not be included in emission calculations when
determining applicability under (a) through (c) above.
(2) The owner or operator of a source that is
exempted from the requirement to obtain an approval
order under (1) above shall no longer be exempt if
actual emissions in any subsequent year exceed the
emission thresholds in (1) above. The owner or
operator shall submit a notice of intent under R307-
401-5 no later than 180 days after the end of the
calendar year in which the source exceeded the
emission threshold.
(3) Small Source Exemption – Registration.
The executive secretary will maintain a registry of
sources that are claiming an exemption under R307-
401-9. The owner or operator of a stationary source
that is claiming an exemption under R307-401-9 may
submit a written registration notice to the executive
secretary. The notice shall include the following
minimum information:
(a) identifying information, including
company name and address, location of source,
telephone number, and name of plant site manager
or point of contact;
(b) a description of the nature of the
processes involved, equipment, anticipated quantities

of materials used, the type and quantity of fuel
employed and nature and quantity of the finished
product;
(c) identification of expected emissions;
(d) estimated annual emission rates;
(e) any control apparatus used; and
(f) typical operating schedule.
(4) An exemption under R307-401-9 does
not affect the requirements of R307-401-17,
Temporary Relocation.
