Subchapter 5 requires potential sources of air contaminants to register with the Division, file an emissions inventory and pay annual operating fees. The owners or operators of permit exempt facilities or de minimis facilities, as these terms are defined in OAC 252:100-7-1.1, are not required to submit an annual emission inventory. Use these instructions to complete an annual facility inventory for the calendar year.
Review the accuracy of all pre-populated
fields and strike through or update incorrect data and make corrections as
needed. All data fields must be reported if applicable or else indicated as not applicable to the facility or operations. There are no "optional" data fields.
1. GENERAL REPORTING GUIDANCE
Report Regulated Pollutants Only. Report the amount of
actual emissions of all regulated air pollutants, including quantifiable excess emissions. The following questions
should be asked in the order shown to determine the correct reporting category
for an emission and so avoid double counting. Once a question can be answered with a ‘yes’, then the
pollutant is reported under that category only, and no more questions need be
asked.
| Is the emission: | ||
| 1. | A Hazardous Air Pollutant (HAP) or any other type of federally regulated pollutant (e.g., Dioxins/Furans)? These are the specific compounds and compound groups defined in the federal Clean Air Act and associated regulations. All currently regulated State Toxic Air Contaminants except ammonia are also HAPs. | |
| 2. | Ammonia (NH3)? | |
| 3. | One of four totally reduced sulfur compounds: hydrogen sulfide, methyl mercaptan, dimethyl sulfide, or dimethyl disulfide? | |
| 4. | Sulfuric acid? | |
| 5. | A pollutant not listed in Appendix P of OAC 252:100 but for which emissions are limited in the Specific Conditions of a current permit? (For more information see www.deq.state.ok.us/AQDnew/emissions/ReportingPollutantsLimitedByPermitOnly.htm.) | |
| 6. | A criteria pollutant or a volatile organic compound (VOC)? | |
If the emission does not fall into any of the above categories – the emission is not a regulated pollutant and should not be reported.
Speciation and Reporting of Particulate Emissions is Dependant on Particle Size:
PM-10 means all particulate matter with an aerodynamic
diameter of 10 micrometers or less (i.e, fine and coarse particle fractions combined).
PM-2.5 means all particulate matter with an aerodynamic diameter equal to or less than 2.5 micrometers (i.e., the fine particle fraction). PM-2.5 is a subset of PM-10. PM-2.5 can be less than or equal to, but never greater than, PM-10. Both pollutants must be reported. Note that all Condensable PM is assumed to be in the PM-2.5 category.
TSP – Do Not Report (Unless emissions are limited by the Specific Conditions of a permit). Particles ranging in size from 0.1 micrometers to about
30 micrometers in diameter are referred to as total suspended particulate matter
(TSP). TSP includes a broad range of particle sizes including fine, coarse, and
supercoarse particles. TSP is the total of all particulate emissions, is not
subject to a fee, and should not be reported.
Note: Oklahoma DEQ does not distinguish between Condensable and Filterable PM. All Primary PM must be reported using the above categories.
Do not double-report HAPs. A regulated pollutant that is either particulate matter or a VOC and is also a HAP should be reported as the specific HAP only. HAPs should be speciated and reported separately where possible. They should not be also reported under the broader PM or VOC categories. The reported total amounts of PM-10/PM-2.5 or VOC (non-HAP) should be adjusted (reduced) as necessary. Following the above procedure will ensure that HAP emissions are not counted twice in the fee process.
Combining Emission Units. Some facilities have a large number of small emission units, which collectively have reportable emissions. In specific cases it is not necessary to track all these individual units but discounting them completely may result in overall emissions being underestimated. The Department believes a potential solution to this is to combine these small sources into one source. Total emissions will be reported, but the other data, such as process rates and operating hours can be averaged for the individual sources. Sources should be combined into logical groupings. For example, all of the small sources at one process unit or building could be submitted together. Contact the Emissions Inventory Section prior to grouping or combining emission units and processes.
Emissions Caps. A facility may have a facility-wide cap or an emission unit group cap. Although the method of demonstrating compliance with the cap is addressed in the permit, each emission unit must be reported separately and individually.
Lower Reporting Cut-off. A lower cut-off or minimum amount of emissions of an individual pollutant that should be reported is not defined by rule. Emissions of each regulated pollutant should be reported in tons to three decimal places. The trace checkbox should be used to indicate that emissions of a regulated pollutant have been estimated to be less than 0.001 tons per year.
Change in Ownership or Company/Facility Name. The owner or operator of any facility that is required to submit an emissions inventory shall notify the Department in writing no later than 10 days following any transfer of ownership. Also, the Department should be notified in writing of any company or facility name change amount of the actual emissions, including quantifiable excess emissions.
Confidential: Indication of confidentiality of process information. Emissions data that may be held as confidential is certain information, which if made public, would divulge methods or processes entitled to protection as trade secrets. Confidential information must be severable and “CONFIDENTIAL” should be marked on every applicable page. A “PUBLIC” copy of the report should also be provided with all of the confidential information removed. The Department shall hold and keep as confidential any information declared by the provider to be a trade secret and may only release such information upon authorization by the person providing such information, or as directed by court order.
Emissions Information that may be held as confidential includes in part the following:
Emissions Information that may not be held as confidential includes in part the following:
Due Date. All content, necessary information and requested data must be submitted prior to April 1 for an emissions inventory to be considered complete. Upon receiving a written demonstration of good cause the Director may grant an extension for submittal beyond the April 1 deadline.
Certification by Company Responsible Official. The emissions inventory shall contain a certification by a company responsible official (as defined in OAC 252:100-1-3) of the truth, accuracy, and completeness of the document, as required by OAC 252:100-5-2.1(f). This certification shall be signed by a responsible official and shall contain the following language:
“I certify, based on information and belief formed after reasonable inquiry, the statements and information in the document are true, accurate, and complete.”
Hardcopy Submittal. The Turn Around Document contains a cover sheet with
general facility information, followed by one or more pages for each emission unit, and finally a plant summary page used for certification that must be
signed by a “Responsible Official”. Use blank forms for any changes or
additions to the pre-printed inventory.
In general, one
Point Page will usually be needed for each emission unit and additional Pollutant Pages if there are emissions of more than two pollutants. Visit the
Emissions Inventory part of the DEQ website at http://www.deq.state.ok.us/AQDnew/emissions
for more information plus help with completing Turn Around Documents and
submitting emissions inventories. There, you will find other reference tables
and copies of blank Turn Around Document forms on our “Turn Around Documents:

County: This
box should contain the county where the facility is located.
Legal Description: The sub-section, section, township, and range
of the facility.
Geographic Coordinates: Please
provide the Latitude and Longitude for the main gate or entrance to your facility. It is not necessary to provide
both types of coordinates. If pre-populated information is present on your form or in Redbud then it should be updated ONLY if you have valid GPS
(Global Positioning System) data.
Note: All geographic coordinates must be provided for the same datum, specifically NAD (North American Datum) 83, which is the same as WGS (World Geodetic System) 84. This reference system is predominantly used today, such as for GPS data. However, some USGS topo maps are based on the earlier NAD 27. In that case, the coordinates must be converted to NAD 83 coordinates, which can vary by a kilometer or more.

5. Emission Release Point INFORMATION
Stack/Emission Release Point Name: Describes the point or area at which emissions are released into the environment, via a stack or fugitive release. A release point can define the area over which fugitive emissions occur.
Stack/Emission Release Point Type: Selections are: Fugitive,
Vertical, Horizontal, Goose Neck, Vertical with Rain Cap, Downward-Facing Vent
Stack/Emission Release Point Status: The operational status of the stack/emission release point. The possible selections are:
5.1 STACK PARAMETERS (Do not apply to Fugitive Emission Release Points)
Stack Height: Height above grade of the stack in feet.
Stack Diameter: Diameter of the stack in feet. For non-round stacks, the diameter equals the square root of the length times width multiplied by 1.128 as stated in the following equation:
![]()
Gas Exit Temperature: The temperature of the exit gas stream in degrees Fahrenheit.
Flow Rate: Numeric value of stack gas flow rate in actual cubic feet per minute (acfm).
Gas Exit Velocity: The exit velocity of
the exhaust stream in feet per second (fps). To convert the Flow
Rate to Gas Exit Velocity divide the flow
rate (acfm) by π r
2 and by 60 seconds/minute as shown in the following equation:
Gas exit velocity (fps) = flowrate (acfm) ÷ (π × r 2 × 60)
5.2 FUGITIVE RELEASE PARAMETERS (Do not apply to Stacks)
Fugitive Height: Height above grade in feet of
emission release point for emissions not routed through a stack (tanks,
fugitives, stock piles, etc.). Where
there is no identifiable stack, provide the height in feet above ground at
which the emissions enter the atmosphere. This
may also be appropriate for stacks with a minimal flow rate (e.g., still vents,
lab hoods). If stack dimensions
are reported the Fugitive Height is zero (0).
6. Emission PROCESS INFORMATION
SCC: The EPA Source Classification Code for the process. The SCC describes an emissions process or activity. At general instruction SCC table
you will find a table with all SCCs (in Microsoft Excel format). A smaller table, "SCC 3-Digit Primary Point Source Categories," found at general instruction SCC 3-Digit table, lists the major industry groups. It is important to stay within a specific industry group. For more information
about SCCs, see the EPA’s Chief website (http://www.epa.gov/ttn/chief),
in particular the AP-42 emission factors documentation and the FIRE program.
Emission Process:
Description of each process or activity at a particular emission unit (this description is assigned by the SCC). A single emission unit may have two or more processes (and so SCCs) if more than one material is used. For example, a single boiler will have two SCC's is it burns both fuel oil and natural gas.
Material: The substance
from which the pollutants were created by each process. Depending on the type of source category, material may
refer to the type of fuel combusted, raw material processed, product
manufactured, or material handled or processed. A table of the material descriptions to be used can be found at: general instruction materials table.
Material Input/Output: Indicate whether the material defined above was:
Process Rates: Hourly, Daily, and
Annual process or activity rate, measured by the process rate units which are typically defined by the process SCC.
The rate is a measurable factor or parameter that relates directly or indirectly to the emissions of an air pollution source. Note that this is the rate of the process that produces emissions, and is not necessarily the amount of throughput of material passed through a piece of equipment. For example, for a compressor engine that is burning natural gas, the process rate would refer to the amount of natural gas burned by the engine, not the amount of gas compressed by the engine-driven compressor.
Depending on the type of source category, activity information may refer to the amount of fuel combusted, raw material processed, product manufactured, or material handled or processed. It may also refer to population, employment, number of units, or miles traveled. Activity information is typically the value that is multiplied by an emission factor to generate an emissions amount that should be expressed as tons per year (tpy).
| Hourly | Maximum hourly rate at which the process
unit can operate. This figure is used in modeling studies. |
|
| Daily | A rate that characterizes how, on a representative day, a particular process unit operated during the reporting year. | |
| Annual | Actual annual process rate. |
Process Rate Units: The units of measure used to quantify the rate of the activity that produces air emissions (these are typically assigned by the SCC).
6.1 DESIGN RATINGS AND FUEL COMBUSTION DATA (Applies to certain processes only)
Design Capacity: Report only if unit is a boiler, turbine or an internal combustion engine. Design Capacity of the process equipment operating at 100% of the designated rate. For a boiler, Design Capacity is based on the reported maximum continuous steam flow. Report the value for the design
capacity for a boiler as MMBTU/Hr (Million British Thermal Units per Hour). For a turbine report the design capacity as Horsepower (hp) or Megawatts (MW). For an internal combustion engine report the design capacity as Horsepower (hp).
Fuel Heat Content: The heat content of a fuel in Million British Thermal Units per the standard unit of measure for that type of fuel, that is:
MMBTU per Million Standard Cubic Feet (gaseous fuels)
MMBTU per Ton (solid fuels)
MMBTU per 1000 Gallons of oil (liquid fuels)
Sulfur
%: Percent
Sulfur, by weight, in the process fuel. The value must be between 0.01% and 10%, inclusive.
Ash
%: Percent
Ash, by weight, in the process fuel. The value must be between 0.01% and 20%, inclusive.
6.2 TEMPORAL Operating INFORMATION
Hours per Day must be a number between 0 and 24 (inclusive). Typical hours per day that the emitting process operates during the inventory period.
Days per Week must be a number between 0 and 7 (inclusive). Typical days per week that the emitting process operates during the inventory period.
Weeks per Year must be a number between 0 and 52
(inclusive). Typical weeks per year that
the emitting process operates during the
inventory period.
Actual Hours per Year represents the total actual hours the process
operated during the calendar year for which the emissions inventory is being submitted. For leap
years, Actual Hours per Year must be a number between 0 and 8784 (inclusive).
For all other years, this must be a number between 0 and 8760 (inclusive).
Seasonal
Operating Fractions: The
fraction of the total operation that occurs in each season. Report these in
decimals (25% should be reported .25). This expresses the part of the actual annual activity information based on
the four seasons (e.g., production in summer is 40%, i.e., 0.40 of the year’s
production). The total Seasonal Operation shall equal 1.00, i.e., 100%.
Spring — The percentage of the total annual activity that a process operates during the Spring months (March, April, May).
Summer —The percentage of the total annual activity that a process operates during the Summer months (June, July, August).
Fall —The percentage of the total annual activity that a process operates during the Fall months (September, October, November).
Winter —The percentage of the total annual activity that a process operates during the Winter months (December, January, February, all from the same reporting year, i.e., Winter 2008 = January 2008 + February 2008 + December 2008).
6.3 Applicable Regulations For THIS Process
Report the relevant Federal or State regulation that this particular process at this particular facility is subject. One or more regulations may be reported to which an emissions unit or process is subject. Examples include but are not limited to, 40 CFR § 60.40 (Subpart D), OAC 252:100-33 (Control of Emissions of NOx).
Regulation Type can be Area Source, MACT, NSPS, etc..
CFR Part, Subpart is the relevant part of the Code of Federal Regulations, if applicable.
Start Year is when the regulation became applicable to this particular process as this particular facility.
7. EMISSIONS INFORMATION
Pollutant: Name of the substance, compound or compound group of which emissions are produced.
CAS: Chemical Abstract Services registration
number for the pollutant.
Method of Calculation: The Approved Method used for computing or measuring emissions.
Emission Factor: The ratio relating emissions of a specific pollutant to an activity or material process rate. The numeric value of this field is dependent upon the calculation method and the emission factor numerator and denominator units. A pollutant-specific emission factor is typically expressed as pounds per process rate units. Uncontrolled emission factors should be reported here. Where applicable, reduce the resulting amount of emissions by the actual capture and control efficiencies of the control scenario.
Numerator Units: Usually pounds but can be another unit, such as grams where the emission factor is grams per horsepower-hour (g/Hp-Hr).
Denominator Units: These units are usually the same as the process rate units. For example, for a natural gas boiler the process rate is measured in million standard cubic feet; the emission factor unit numerator would be pounds and the denominator would be million standard cubic feet (lbs/mmscf).
Note: For calculation methods where there may not be one single emission factor used to compute the actual emissions (e.g., Tanks, GRI-GlyCalc 4, CEMS), enter zero (0) in the emission factor field and for the numerator and denominator units select:.
Actual Emissions (Tons): Amount of actual annual emissions of the pollutant, after application of air pollution control equipment, reported in tons per year. The actual emissions for a plant, emission unit, or process—measured or calculated—that represents a calendar year. This total shall include emissions from fugitives, upsets, startups, shutdowns, malfunctions, and excess emissions.
Reference: The specifc source or material containing the method of calculation and factor. For AP42, use the Table number, e.g., Table 1.4-1. For Permit Factor, insert the permit number. Fire will list the AP42 section, table or EPA document. Other References may be EPRI, RMA, or UEF, etc. The following may or may not have a Reference: Cont. Emissions Monit. Data (CEMS) , DEQ Approved Method, EPA Reference Method Stack Test, Fuel Usage Data , GRI-GLYCalc , Manuf. Test Data (w/ DEQ approval), Mass Balance, Similar Unit EPA Refrence Method Test, TANKS, and Vasquez-Beggs.
Method/Factor Includes Control Efficiency: Check this box if the emission factor includes the control efficiency.
Excess Emissions (Tons): Any "Excess Emissions" as defined by OAC 252:100-1-3, Definitions. This amount shall be included in the Total Amount of actual emissions.
Permit/Rule Limit (Tons/Year): The total amount of any regulated air pollutant which is subject to an emissions limiting standard, either by rule or permit condition contained in an enforceable permit or potential to emit, or for grandfathered sources, emission limits based on maximum design capacity and considering all applicable rules.
Capture Efficiency: The percentage of air emission that is directed to the control equipment, or an estimate of that portion of an affected emissions stream that is collected and routed to the control measures, when the capture or collection system is operating as designed.
Control Scenario (Primary and Secondary): Control system, abatement equipment or approach applied to reduce emissions of the pollutant.
Control Efficiency (Primary and Secondary): The amount of actual air emissions prevented from being emitted by the control scenario. The actual efficiency should reflect control equipment downtime and maintenance degradation. Report as a percentage.
