AIR TOXICS APPLICATION FORM
ATTACHED ARE THE FOLLOWING:
1. Toxics Data Form (TDF)
2. Air Toxics Regulations
I. GENERAL INSTRUCTIONS
15A NCAC 2D .1100 and 2H .0610
G
page I of 3
4/17/90
This section must be completed for facilities required to obtain a toxic air
permit by EMC regulation 15A NCAC 2H .0610 and for facilities who emit one or
more of the regulated air toxics listed in 15A NCAC 2H .0610(h). As 'specified
in 15A NCAC 2H .0610, if facility wide emissions for a listed toxic is above
the amounts listed in 15A NCAC 2H .0610(h), then- a toxic air permit is
required. Specific exemptions from toxic air permitting are contained in 15A
NCAC 2H .0610.
The attached Toxics Data Form (TDF) must be completed for each air emissions
source that emits a listed air toxic pollutant. Include listed air toxic
emissions from stacks, vents, chimneys, processes, and fugitive sources.
Propose maximum emissions for the listed toxics in 15A NCAC 2H .0610(h) that
are emitted by the source. The source ID NO. must correspond to the source ID
NO. on item 6 of Form A. For assistance in completing this form please contact
the approriate DEM field office listed on the back of Form A.
To comply with 15A NCUAC 2H .0610(b), for each listed air toxic emitted from the
entire facility in excess of the amounts listed in 15A NCAC 2H .0610(h), air
dispersion modeling is required as part of the toxic air permit application.
Prior to submitting the modeling, the modeling plan must be submitted by the
applicant and approved by this Division. Section III of this form lists items
needed in a modeling plan. Applicants applying under the provisions of 15A NCAC
2H .0610(b)(2) or (c) should contact the Air -Quality S��qt:Lq -to discuss -
determination. r 7 oMp ER64�-
II. COMPLETING THE ATTACHED TOXIC DATA FORM
Complete a separate form for each air emission source emitting a listed air
toxic pollutant. Form data items are described as follows:
ITEM (1) Source ID
Use the same source identification number as assigned on item 6 of Form A
of the AQ -22.
ITEM (2) Source Description
List the source type such as incinerator, spray booth, coal boiler, or
storage tank. Include air cleaning devices if applicable.
ITEM (3) Exhaust Type
Enter the exhaust configuration of the emission source using the codes at
the bottom of the Toxic Data Form. For the purposes of this application
the following definitions apply:
A. Unobstructed Vertical Stack or Chimney - any point in a source designed
to emit solids, liquids or gases into the air, including a pipe or a duct
but not including flares and that is constructed in a vertical direction
and is void of restrictive obstructions, e.g., rain caps.

. G
page 2 of 3
B. Obstructed or Nonvertical Stack or Chimney - any point in a
source designed to emit solids, liquids or gases into the air, including a
pipe or a duct but not including flares and that is either constructed in
a nonvertical direction or has a restrictive obstruction, e.g., rain caps.
C. Other Point Source - an identifiable piece of equipment that is used as
a complete unit to accomplish a specific purpose or produce a specific
product which results in an emission through a vent or functionally
equivalent opening excluding stacks or chimneys. Describe the particular
point source.
D. Fugitive Emissions - those emissions which could not reasonably pass
through a stack, chimney, vent or other functionally equivalent opening.
This includes ponds or lagoons which are used as reservoirs for cooling
water, wastewater, or other liquid mixtures. Routine leaks entering the
atmosphere from pipes, valves, tanks, condensers or other equipment are
also considered fugitive emissions and must be reported.
E. Other - all other emission types not identified by A, B, C or D.
Describe the particular exhaust configuration falling within this
category.
ITEM (4) Toxic Emitted To Atmosphere
For the source, list all the toxic pollutants in 2H .0610(h) that are
emitted to the outside atmosphere. Use additional forms as needed.
��P!S if �hfi Nd7m
List the number of the toxic pollutant as specified in 2H .0610(h). For
example the number for toluene is (98), the number for ammonia is (5).
ITEM (6) Requested Maximum Emissions
For each toxic pollutant emitted, for the time periods listed in 2H
.0610(f) list the maximum requested emission rate(s) in pounds per year,
pounds per day, pounds per hour, or in pounds per 15 minutes. Emissions
proposed are for annual periods over a calendar year, for 24-hour periods
from midnight to midnight, for one-hour periods beginning on the hour, and
for 15 -minute periods beginning on the hour or 15, 30, or 45 minutes after
the hour.
ITEM (7) Calculation Method
Enter the letter(s) of the calculation method using the codes at the
bottom of the Toxic Data Form which best describes the method(s) used to
determine the emission rates in item (6).
ITEM (8) Stack or Vent Diameter
Give the inside exit diameter of the stack or vent in feet to the nearest
tenth of a foot.

G
page 3 of 3
ITEM (9) Stack or Source Height
Give the actual height in feet above the ground level of the emission
outlet. For a fugitive emission give the height from which the emissions
originate.
ITEM (10) Exit'Velocity
Enter the exit velocity in feet per second for the emissions at the
maximum operating rate. For example:
[Exhaust Volume (acfm)] / [Stack or Vent Area (ft 2 )] x [min/60 secl
[Exit Velocity(ft/sec))
ITEM (11) Exit Temperature
Enter the exit temperature in degrees Farenheit for the emissions at
the maximum operating rate.
III. MODELING PLAN REQUIREMENTS
Air toxics modeling requirements are contained in 15A NCAC 2D .1106. Applicants
submitting ambient dispersion modeling to comply with 15A NCAC 2H .0610(b) must
first submit a modeling plan to this Division and receive approval of that plan
prior to submitting the toxics modeling demonstration.
The modeling plan should include the following information:
1) A diagram of the plant site, including locations of all
existing and proposed stacks and associated buildings;
2) A list of on-site building dimensions (height, width, and
3) A diagram showing property boundaries, including a scale, key
and a North indicator;
4) The location of the site on a United States Geological Survey
(USGS) map;
5) Calculation of Good Engineering Practice Stack Height for each stack;
6) Discuss all aspects of the project not accounted for in a
simple flat terrain model. These include cavity calculations,
impacts on rolling and complex terrain, building wake effects, and
urban/rural considerations;
7) Discuss reasons for model selections;
8) Discuss meteorological data to be used; and
9) Any other pertinent information.
