Permits in General

Do I Need A Permit?

Permitting and Registration thresholds are based on facility wide emissions and operations. Once a facility is required to obtain a permit/registration, all emission sources need to be accounted for unless the source qualifies as insignificant under Appendix A, Group B (see appendix at end of these instructions).

Unless listed below, a facility does not require an air permit or registration.

You must submit a Registration (Regulation 18.315) if your emissions are:

You must obtain a minor source permit if your actual emissions are:

You must obtain a minor source permit if your facility is one of the following (regardless of emissions):


 

You must obtain a minor source or Title V permit if your facility is subject to a rule under 40 C.F.R. §§ 60, 61, or 63 as of June 27, 2008 (meaning the rule has to be in effect by that date or it is not considered in this requirement), except for:

You must obtain a Title V (Major Source) permit if your emissions are:

You also must obtain a Title V (Major Source) permit for the following sources/facilities:

 


 

What Type Of Permit Application Do I Need To Submit?

 

Except for General Permits, all permit application forms are contained in the same single package. There are no separate application forms for initial permits or modifications to an existing permit. Complete only the sections necessary as indicated in the forms, instructions and checklists based on permit and application type. If you complete your application form in ePortal, then the ePortal system will guide you to the correct forms that need to be completed based on your selection of the permit and application type.

Initial applications must contain information on all emission sources at the facility.

Registration Applications always contain facility wide information. An approved Registration is valid unless operations change at the facility so that the initial application is no longer representative of operations. In that case, submit a complete new registration to the Division of Environmental Quality.

Modifications are to add or change emission sources listed in the permit. Generally, only information regarding the change is needed.

Minor Modifications and De Minimis applications are small modifications to a permit that allow for expedited review and approval by the Division of Environmental Quality. Refer to the definitions in Regulation 26 and 19 for details on qualifying changes and the attached checklist used by the Division of Environmental Quality.

Administrative Amendments are limited to typographical errors, insignificant sources and other such changes. Refer to the definitions of Administrative Amendment in Rule 19 and Regulation 26.

Renewals are required for major source/Title V permits only. These permits are valid for 5 years. The facility must apply for renewal. Application for renewal must be received and complete at least 6 months, but no more than 18 months before the date of permit expiration. Permit expiration terminates a source’s right to operate unless a timely and complete renewal application has been submitted, in which case the existing permit shall remain in effect until the Division of Environmental Quality takes final action on the renewal application. Renewal permits are subject to the same application and procedural requirements that apply to initial permit issuance, that is, all information on all sources needs to be included.

General Permits are standardized permits for specific categories of facilities. General permits are an option to a traditional permit application. A facility can apply for coverage under a general permit by submitting the appropriate Notice of Intent (NOI). The general permit is a pre-written permit containing terms and conditions and does not change based on the facility. Refer to the DEQ, Air Permits Branch website for a current listing of general permits and application forms (NOIs).

 


 

General Information on Air Permitting

 

Prohibitions on Construction and Installation:  No proposed new facility subject to Minor Source Permit or Title V requirements can begin construction or modifications before obtaining the proper air permit if one is required. Exceptions are:

Minor Sources can begin construction of a new emissions unit or begin modification to an existing emissions unit if the modification qualifies and has been approved by the Division of Environmental Quality as a De Minimis change in accordance with Reg.19.407(C) or Reg.18.307(C).

Title V/Operating Permits sources can begin construction of a new emissions unit or begin modification to an existing emissions unit if the modification qualifies and has been approved by the Division of Environmental Quality as a minor modification in accordance with Chapter 10, Reg.26.1002.

Applicable Regulations:  Before completing this application, the applicant should review all state and/or federal air pollution control regulations that apply to the facility. Not all regulations will apply to all sources. This information is provided as a general overview to aid in determining which applicable regulations pertain to a source.

The Arkansas Air Pollution Control Code (the Air Code, Regulation No. 18):  This regulation is a State regulation and is applicable to any source that emits or has the potential to emit any air contaminant. Permit requirements under Regulation No. 18 are not federally enforceable. The Air Code applies to all permits.

Rules of the Arkansas State Plan of Implementation for Air Pollution Control (SIP, Rule 19) pertaining to air pollution control requirements for sources subject to the federal Clean Air Act, including Prevention of Significant Deterioration (PSD) regulations.

Regulation of the Arkansas Operating Air Permit Program (Regulation No. 26). This contains the requirements for Major Source/Title V air permits.

Standards of Performance for New Stationary Sources (NSPS) contained in 40 C.F.R. § 60 pertaining to specific categories of new, modified, and reconstructed sources of air pollutants.

The federal NSPS, 40 C.F.R. § 60, apply to certain categories of new, reconstructed, and modified stationary sources of air pollution. The standards set emission limits for specific pollutants for the emission source category. For most affected source categories, the standards require reporting and emission testing requirements. The Division of Environmental Quality has been delegated the authority to administer and enforce most NSPS. For a list of the NSPS subtitles, please contact the Division of Environmental Quality.

National Emission Standards for Hazardous Air Pollutant (NESHAP) contained in 40 C.F.R. §§ 61 and 63 and Section 112 of the federal Clean Air Act.

The federal NESHAP, 40 C.F.R. §§ 61 and 63, apply to certain categories of stationary sources, both existing and new, emitting air pollutants designated as hazardous under Section 112 (Title III) of the federal Clean Air Act (CAA). 40 C.F.R. § 61 is the existing NESHAP regulations, 40 C.F.R. § 63 includes the Maximum Achievable Control Technology (MACT) standards, and Section 112 of the Act pertains to the promulgation of the list of 187 Hazardous Air Pollutants (HAPs). The appendices to these instructions contain a list of the 187 HAPs.

Prevention of Significant Deterioration (PSD) Regulations: DEQ adopted the federal PSD regulations, 40 C.F.R. § 52.21, with minor revisions and additional requirements, as part of the SIP. The intent of the PSD regulations is to prevent the deterioration of air quality in areas where air quality is better than the National Ambient Air Quality Standards through preconstruction review of sources.

A new source is defined as major, and therefore subject to PSD review, if its “potential to emit” (for PSD purposes this is equivalent to the proposed maximum annual emissions, after the application of control equipment) exceeds 100 tons per year of any pollutant regulated under the Clean Air Act, if the source is included in any of 28 named source categories, or 250 tons per year if the source is not included in any named source category. A modification is major, and therefore subject to PSD review, if the net emissions increase of any regulated pollutant, by itself, would meet the above definition of a new major source. If an existing source is already major for any regulated pollutant, as defined above, a modification is major, and therefore subject to PSD review, if the net emissions increase of any regulated pollutant exceeds the significance level for that pollutant, as defined in the PSD regulations.

Sources that may be subject to PSD review should review the regulations to determine applicability and analyses required. DEQ recommends a pre-application meeting.

If a source is subject to PSD review, the following information will be required:

·         Information necessary to determine compliance with all SIP, NSPS, and NESHAP applicable emission limitations.

·         Information necessary to determine application of the best available control technology (BACT) to the emissions of all applicable pollutants.

·         An ambient air impact analysis that includes modeling using USEPA approved computer models and techniques in conformance with guidance from the USEPA.

·         Information as required to perform visibility and additional impact analysis.

·         Ambient air quality data for applicable pollutants, subject to the exemptions contained in the PSD regulations. Up to one year of ambient air quality monitoring may be required to be conducted by the applicant before an application can be considered complete. A monitoring plan shall be submitted to the Division of Environmental Quality for approval before initiation of monitoring.

Greenhouse gases (GHGs):  GHG is a combination of six pollutants (carbon dioxide, nitrous oxide, methane, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride) and quantified as a CO2 equivalent (CO2e). For each pollutant, its emission rate (tpy) is multiplied by its global warming potential (GWP). That product is summed along with the products determined for the other pollutants to obtain the total CO2e (tpy).

For example, a source emitting 10 ton per year (tpy) of CO2, 3 tpy of methane and 1 tpy of nitrous oxide would have a CO2e of (10 x 1) + (3 x 25) + (1 x 298) = 383 tpy CO2e

Facilities applying for a permit issued under Rule 19, Chapter 9: PREVENTION OF SIGNIFICANT DETERIORATION that include an increase of 75,000 tpy CO2e for GHG need to include details on emission rates and other GHG information. Consult with the Division of Environmental Quality if you are unsure of these regulations.

 

112(g) Applicability:  For major stationary source of Hazardous Air Pollutants (HAPs), when no applicable federal emission limitation has been promulgated, the Clean Air Act requires the state permitting authority to determine a MACT emission limitation on a case-by-case basis. This rule assures that effective pollution controls will be required for new major sources of air toxics during the period before EPA can establish a national MACT standard for a particular industry. Section 112(g) applies to the owner of operator of a constructed or reconstructed major source of hazardous air pollutants (HAPs). Section 112(g) requires MACT-level control of air toxics when a new major source of HAP is constructed or reconstructed.

The application requirements for a case-by-case MACT determination are outlined in 40 C.F.R. § 63.43(e). If a source is subject to 112(g) review, the following information will be required:

·         A brief description of the major source to be constructed or reconstructed and identification of any listed source category or categories in which it is included.

·         Any federally enforceable emission limitations applicable to the constructed or reconstructed major source.

·         DEQ may ask for the maximum and expected utilization of capacity of the constructed or reconstructed major source, and the associated uncontrolled emission rates for that source, to the extent DEQ needs this information to determine MACT.

·         DEQ may ask for the controlled emissions for the constructed or reconstructed major source in tons/yr at expected and maximum utilization of capacity, to the extent DEQ needs this information to determine MACT.

·         A recommended emission limitation for the constructed or reconstructed major source consistent with the principles set forth in 40 C.F.R. § 63.43(d).

Confidential information:  All construction, emission, and operating information contained in the permit application and any changes, modifications, or alterations in the permit application submitted to the Division of Environmental Quality in writing will become part of the Division of Environmental Quality’s permanent files and will be available for public inspection unless clearly marked confidential and approved as confidential by the Division of Environmental Quality’s legal staff. The applicant must submit the confidential applications separately from publicly available information, and accompanied by a notarized affidavit of confidentiality. In addition, submit a complete public (non-confidential) application to DEQ. At this time, confidential information should not be submitted through ePortal.

Permit Fees:  Minor Source and Title V permit fees are based on the permitted volume of air pollutants emitted from the facility. The applicant must pay the initial permit issuance fees or permit modification fees and any past due DEQ fees before the final permit issuance. The applicant must pay the annual permit fees to keep the permit active. The Division of Environmental Quality will calculate the permit fees (in accordance with Chapter 5 of Regulation #9) and send an invoice to the facility. A copy of Chapter 5 of Regulation #9 can be found on our website.

Electronic Application Submittal:  ePortal should be used to electronically submit applications.

Permit Processing:  DEQ will not consider an application complete until the applicant submits all information required to consider the application. An application consists of completed permit application forms along with the enclosures and attachments referred to in these instructions and any additional information required for Prevention of Significant Deterioration (PSD) applications or MACT determinations. Upon declaring the permit application administratively complete, other than minor modifications, de minimis or administrative amendments, the Division of Environmental Quality will provide a public notice to the permittee to publish in the local paper. A 10-day comment period for the receipt of application will begin on the date of publication of the notice. DEQ cannot issue a draft permit before the close of the 10-day period, pursuant to Act 163 of 1993.

The project engineer will review each application for technical completeness of information submitted. During the review, DEQ may contact the applicant for clarification or additional information. When the applicant submits all pertinent information, the project engineer will draft a permit and forward the draft permit to the Office of Air Quality staff for in-house review.


 

A draft public notice and comment period is required for all draft permits except De Minimis and Administrative Amendments. The draft public notice results in a minimum period of 30 days after publication of the notice before DEQ can issue a final permit. A proposed Operating Air Permit is subject to a 45 day EPA comment period. In some cases, the draft permit and EPA comment periods can run concurrently. Final permit issuance may be further delayed if a public hearing or substantial response to comments is necessary. The applicant is responsible for the costs associated with publication of public notices.


Application Form Completion Instructions

Use the checklists in the appendix to these instructions as a guide to determine the appropriate attachments to submit with the application forms. Failure to submit the appropriate attachments may result in an administratively incomplete application. Note that not all of these elements are required for all permit applications.

 

Explanation for Not Using ePortal

Registration Information

Complete this section only if you are applying for a Registration. This section plus the General Information, Applicant Information, Applicable Federal Regulations, Process Information, emission calculations part of the Emission Information Section, Certification of Application, and a Disclosure Statement constitute an application for Registration. If you are not applying for a Registration, check the box to indicate that you are skipping this section.

22.              Total Actual Emissions:  Denote the facility’s total tons per year (tpy) for each pollutant (this value does not always correspond directly to the maximum hourly emission rates). This value may be limited by hours of operation limits or by throughput/production limits. If this value indicates less than continuous operation at maximum operating rates, the permittee should clearly denote in the supporting calculations the factors (i.e. production limits, or hour of operation limits, etc.) used to limit the emission rates. If the facility is proposing to operate on a continuous basis, the applicant should calculate the annual emissions based upon 8,760 hours per year of operation. Round this value up to the nearest tenth or report two significant digits for criteria pollutants. Do not round for other pollutants. Enter “0” if the pollutant is not emitted.

Title V Information

Complete this section for Title V/Major Source Air Permit Applications only. These questions do not apply to minor source or Registration applications. If you are applying for a Title V administrative amendment, minor source permit, or a registration; check the box to indicate that you are skipping this section.

23.              Neighboring States:  If the facility location is within fifty miles of a neighboring state, select the appropriate state(s). If no state is within fifty miles of this facility, select the “No State within 50 Miles” option.

24.              Compliance Plan and Schedule:  The applicant must submit a compliance plan and schedule if the permittee is out of compliance. If the facility is in compliance, selecting the appropriate checkbox on the Certification of Compliance qualifies as the Compliance Plan.

The Compliance Plan requires the following:

A compliance plan for all part 70 sources that contains all the following:

                         a.                        A description of the compliance status of the source with respect to all applicable requirements.

                        b.                        A description as follows:

i.                    For applicable requirements with which the source is in compliance, a statement that the source will continue to comply with such requirements.

ii.                  For applicable requirements that will become effective during the permit term, a statement that the source will meet such requirements on a timely basis.

iii.                For requirements for which the source is not in compliance at the time of permit issuance, a narrative description of how the source will achieve compliance with such requirements.

The Compliance Schedule must:

Provide the requested information concerning current and future compliance plans and schedules of the facility with applicable requirements.

                         a.                        For applicable requirements with which the facility is in compliance, a statement that the facility will continue to comply with such requirements.

                        b.                        For applicable requirements that will become effective during the permit term, a statement that the facility will meet such requirements on a timely basis, unless a more detailed schedule is expressly required by the applicable requirement.

                         c.                        A schedule of compliance addressing all applicable requirements for which the facility is not in compliance at the time of permit issuance. Such a schedule shall include a schedule of remedial measures, including an enforceable sequence of actions with milestones, leading to compliance with any applicable requirements for which the source will be in noncompliance at the time of permit issuance. This compliance schedule shall resemble and be at least as stringent as that contained in any judicial consent decree or administrative order to which the source is subject. Any such schedule of compliance shall be supplemental to, and shall not sanction noncompliance with, the applicable requirements on which it is based.

                        d.                        Provide a schedule for submission of certified progress reports no less frequently than every 6 months for sources required to have a schedule of compliance to remedy a violation.

                         e.                        For each source subject to the acid rain provisions, requirements specified in this section shall apply and shall be included in the acid rain portion of a compliance plan. The plan shall identify the schedule and method(s) the source will use to achieve compliance with the acid rain emissions limits.

25.              Compliance Assurance Monitoring Plan: contained in 40 C.F.R. §§ 64, 70, and 71. Compliance assurance monitoring (CAM) applies to major stationary sources of air pollution required to obtain a Title V operating permit. The CAM rule requires owners or operators of such sources to conduct monitoring satisfying particular criteria established in the rule to provide a reasonable assurance of compliance with applicable requirements under the Clean Air Act. The CAM rule aims to have owners and operators maintain control devices at the levels that assure compliance. Monitoring will focus on emissions units that rely on pollution control device equipment to achieve compliance with permitted emission limits. The rule allows owners and operators to design CAM plans on current requirements and operating practices; to select representative parameters upon which compliance can be assured; to establish indicator ranges or procedures for setting the indicator ranges for the parameters; to use performance testing and other information to verify the parameters and ranges; and to correct control device performance problems as expeditiously as practicable. CAM plan examples may be found at: https://www.epa.gov/air-emissions-monitoring-knowledge-base/compliance-assurance-monitoring-technical-guidance-0.

26.              112(g) Applicability:  If the facility will engage in construction or reconstruction that will require a 112(g) application, please select the appropriate option. This applies to Title V permits only. Refer to the 112(g) section under the General Information on Permit Applications section above. If the application triggers 112(g), attach the 112(g) application.

27.              Title VI Applicability:  Items a, b and c determine Title VI applicability. Select the appropriate answer option, “yes” or “no” for each item. For item b, if the refrigeration charge of the unit is unknown, contact the equipment manufacturer or a vendor to obtain this information. In general, household size refrigerators and air conditioners will have a charge of less than 50 pounds per unit.

28.              Accidental Release ApplicabilityIndicate if the facility is subject to and in compliance with the Accidental Release Prevention requirements of Section 112(r) of the Clean Air Act by selecting the appropriate option. If the facility is subject to the requirements, but is not in compliance, attach a § 112(r) compliance plan. If unknown whether the facility is subject to these provisions, refer to 40 C.F.R. § 68. “Threshold Quantities” are listed in 40 C.F.R. § 68.130. If the facility stores, produces, or transfers in excess of the “Threshold Quantity” of the listed substance, the facility is subject to the requirements outlined in Section 112(r). Initially affected facilities must submit a Risk Management Plan (RMP) by June 21, 1999.

The Division of Environmental Quality has not been delegated authority for the 112(r) program and; therefore, is not currently receiving or reviewing submittals. The Division of Environmental Quality, as the permitting authority, must:

                         a.                        verify that the source owner or operator has registered and submitted an RMP or a revised plan when required;

                        b.                        verify that the source owner or operator has submitted a source certification or in its absence has submitted a compliance schedule;

                         c.                        for some or all of the sources, use one or more mechanisms such as, but not limited to, a completeness check, source audits, record reviews, or facility inspections to ensure that the permitted sources are in compliance with the requirements; and

                        d.                        initiate enforcement action as appropriate.

29.              Acid Rain:  Facilities subject to these regulations must apply for permits under 40 C.F.R. § 72. Indicate if the current application/plans are attached to the current permit or if the facility is not subject to the Acid Rain provisions. If the current application/plans are not attached to the current permit, attach a copy of the up-to-date application/plans (available from EPA).

30.              Cross-State Air Pollution Rule (CSAPR)/Transport Rule (TR):  Indicate if the current TR Monitoring Provisions Table is attached to the current permit or if the facility is not subject to the CSAPR/TR monitoring provisions. If the current TR Monitoring Provisions Table is not attached to the current permit, attach the completed Description of TR Monitoring Provisions Table. If unknown whether the facility is subject to these provisions, refer to 40 C.F.R. § 97 Subpart EEEEE. Any stationary, fossil-fuel-fired boiler or stationary, fossil-fuel-fired combustion turbine serving at any time, on or after January 1, 2005, a generator with nameplate capacity of more than 25 MWe producing electricity for sale is subject except as provided in 40 C.F.R. § 97.804(b).

31.              Permit Shield:  A permit shield is provisions added to a Title V permit which state that compliance with the permit conditions shall be deemed compliance with all applicable requirements, at the time of permit issuance, as identified in the shield. Indicate if the facility is requesting that a permit shield (40 C.F.R. § 70.6(f)) be included in the permit. The applicant will need to provide the applicable and inapplicable regulations, relevant sources, and the description of applicability to include in the permit shield.

Prevention of Significant Deterioration (PSD) Information

32.              PSD Applicability:  Indicate if the facility will engage in construction, reconstruction, or modifications requiring a PSD application.

If the facility is a major source as defined in PSD rules the application may be subject to the requirements of Chapter 9 of Rule 19. Attach an explanation of why this permit application is not subject. Be sure to follow the procedures of 40 C.F.R. § 52.21 if determining whether or not a significant emission increase and a significant net emission increase will occur.

 

If this application requires PSD review, submit:

33.              Class I Area Modeling Analysis Form:  Complete the Request for Applicability of Class I Area Modeling form (available on the website). For paper submissions, attach it to the application and email it to airpermits@adeq.state.ar.us. For online submissions, attach the form to ePortal. This form is sent to the Federal Land Manager for their review of the impact of the proposed permit.

34.              Best Available Control Technology (BACT) Analysis:  Attach the BACT Analysis.

35.              Other PSD Analyses:  Attach other PSD Analyses including:  increment, NAAQS, visibility, soils, vegetation, and associated growth.

Applicable Federal Regulations

36.              Applicable Federal Regulations:  If the facility is subject to any of the rules found in 40 C.F.R. §§ 60, 61 or 63, indicate which specific subparts and the affected sources that are applicable to this application. If the application involves additions or changes to operations regulated by one of these subparts, or if the application is for a Title V renewal, a detailed listing of the subpart requirements must be included in the application. Do not list the subparts in general; the list must include details, especially where the subpart has options or requirements based on different equipment specifications. If the permit already contains the correct requirements in specific or plant wide conditions, this can be used for the basis of the list but still must be included.

Process Information

37.              Process Description:  A written description of the process must accompany each application. This must include a description of each relevant piece of equipment and process. The description must be in sufficient detail to provide the permit engineer an understanding of the process. The applicant should place special emphasis on any process or equipment with the potential to emit any pollutants to the atmosphere. The process description should describe material flow between processes (if any) and the source (SN) to which each process is vented should be identified in the narrative. The applicant should describe any work practice standards used to control emissions.

38.              Process Flow Diagram:  The process flow diagram must be in sufficient detail to understand the general process. The process flow diagram must clearly identify all relevant processes or pieces of equipment. All points where raw materials and/or chemicals are introduced into the process and all points where intermediate and/or finished products are removed from the process must be clearly identified with quantities of materials shown. The process flow diagram should show material flow between processes (if any) and the applicant should identify the source number (SN) on the diagram.

39.              Operating Scenarios:  Indicate if this facility has alternate operating scenarios. Describe all alternate operating scenarios the applicant desires for this emission source. Submit a complete set of attachments (i.e. process flow diagrams, process description, emissions calculations, emission rate tables, etc.) for each desired operating scenario. Note:  The permittee may implement any alternative operating scenarios allowed by the permit without incurring a permit modification, thus minimizing delays in production. The permit will allow only those operating scenarios specifically described in the application. Alternate operating scenarios may include the desire to permit two fuels, such as natural gas and No. 2 fuel oil, for a boiler or it may involve the option to produce product X or product Y from the same manufacturing line. Also, phased construction such as using an existing piece of currently permitted equipment (e.g. boiler) until a new piece of equipment is built and operational should be listed as an operating scenario.

Site Information

40.              Plot Plan:  Show the property, to scale, indicate the location of the property boundaries with the applicable scale, the location of all sources of any air pollutants (identified by source number), true north direction, and any other information deemed relevant by the applicant.

41.              USGS Area Map:  Submit one original U.S. Geological Survey topographic map (7.5-minute series) with the location of the facility indicated.

Emission Information

42.              Emission Calculations:  Provide detailed calculations for the emissions of the pollutants. The calculations must contain a detailed explanation of the source of the emission estimation.

43.              Emission Rate Tables:  The applicant must complete an Emission Rate Table form and calculations for each significant air pollutant emission source located at a facility. See the Supplemental Information section for a list of insignificant activities. An emission source is any point at a facility which emits, or is capable of emitting, an air contaminant into the atmosphere. The definition of an air contaminant is “any solid, liquid, gas, or vapor or any combination thereof. The following shall not be considered air contaminants: water vapor, oxygen, carbon dioxide, nitrogen, hydrogen, and inert gases.” For sources under PSD review, GHGs must also be included.

Make as many copies as necessary of the attached Emission Rate Table. Complete a separate emission rate table for each proposed operating scenario, using the same source number for each emission source.

Facilities may submit, on a case-by-case basis, the information required on an emission rate table in an alternative format. The applicant should make a request for an alternative format before the required submittal date of the application in order to allow for modifications to the format, at the discretion of the DEQ, without delaying the application submittal.

                         a.                        STACK DATA:  The stack data is critical since computer modeling uses the stack data. The applicant should ensure that this information is accurate.

i.                    Emission Source No. (SN):  Point and Non-Point sources of air emissions should be given a two or three digit number preceded by “SN” (SN-01, SN-02...SN-999). Maintain the source numbers, if feasible, from the existing permit to identify the same sources in the new application.

ii.                  Date Installed, Date of Last Reconstruction or Date Modified:  Denote the initial year of installation of the equipment in question and, if applicable, the date of the last reconstruction or modification of the equipment.

“Reconstruction” means the replacement of components of an existing facility to such an extent that the fixed capital cost of the new components exceeds 50 percent of the fixed capital cost that would be required to construct a comparable new unit. (This definition is not used to determine whether a permit modification is required, only to determine the date of installation or modification for NSPS applicability determinations).

iii.                Process Description:  Describe the process unit, which generates the emissions in the space provided (ex. Boiler, natural gas fired - 150 MMBtu/hr). The applicant will describe control equipment in a separate section of the table.

iv.                SCC Code:  The EPA uses Source Classification Codes (SCCs) to classify different types of anthropogenic emissions activities. Each SCC represents a unique source category-specific process or function that emits an air pollutant. Refer to EPA websites for a complete up to date listing.

v.                  Stack Height:  Denote the stack’s height above the ground in feet to the nearest foot. If the emissions do not exit a stack (i.e., the emissions are non-point source or fugitive) indicate the height, above ground, where the emissions enter the atmosphere.

vi.                Stack Dimensions:  Denote the inside stack diameter in feet (for example, 3.25 ft. instead of 3’-3”). For non-circular stacks and area sources, report the dimensions in feet (for example, 2.5’ x 1.0’). For non-point source or fugitive emissions, mark this item “Not Applicable” or “N/A”.

vii.              Stack Gas Temperature:  Report the average temperature in degree Fahrenheit (ºF) of the stack gas as it enters the atmosphere. If the emissions are at ambient temperature, enter “ambient”. Do not enter a numeric estimate of the ambient temperature.

viii.            Stack Gas Velocity:  Report the stack gas exit velocity in feet per second at the exit point of the stack. For non-point source or fugitive emissions, mark this item “Not Applicable” or “N/A”.

ix.                Stack UTM Coordinates:  Report the Universal Transverse Mercator (UTM) zone and coordinates of the Stack to the nearest meter. The correct UTM Coordinates are critical for modeling purposes.

                        b.                        CRITICAL OPERATING RATES:  The critical operating rates define the parameters used in drafting the permit. Listed parameters should be relevant to air emissions.

i.                    Maximum Operating Hours:  Enter the proposed maximum operating hours per day, hours per month, and hours per year for the emission point. DEQ defines “Maximum Operating Hours” as 24 hrs/day, 730 hrs/mo, and 8,760 hrs/yr. Using this Maximum Operating Hours to calculate the Potential to Emit (PTE) for all sources is not required but it will reduce the facility/source recordkeeping requirements. If the applicant limits the hours of operation as a means of limiting potential to emit, the permit will limit the hours of operation by permit conditions. Monthly hours of operation may provide maximum flexibility for seasonal type operations or for back-up equipment.

ii.                  PTE Limited by Hours of Operation:  Indicate if the emission calculations use the hours of operation to limit the annual potential emission. Mark “yes” or “no” in the appropriate box.

iii.                Maximum Heat Input Capacity:  Denote all heat input from fuel fired equipment associated with this process, if applicable.

iv.                Fuel Heat Value:  For each fuel, list the average heat value, as fired, in MMBtu per unit, if applicable.

v.                  Fuel % Sulfur:  For processes that utilize fuels (except for pipeline quality natural gas), list the maximum sulfur content. If applicable, identify the maximum sulfur content in the process description. The permit may limit the fuel sulfur content by permit conditions.

                         c.                        MAXIMUM PRODUCTION/OPERATION RATES:

i.                    Using a separate line for each intermediate and/or finished product removed from the process, list the maximum production rates proposed for the source. Using a separate line for each intermediate or raw material, and each solid, liquid, or gaseous fuel, list the maximum feed rates (process weight rates) proposed for the source. Use the same units (gallons, pounds, cubic feet, etc.) for annual as for hourly operating rates. If the permittee uses an operation or production rate below the maximum capability of the equipment to limit the potential to emit, the permit may limit operation to these operating rates by permit conditions. These rates should be in the units normally used by the facility to quantify usage (i.e. paint measured in gallons). Hourly throughput maximums are rates that are never to be exceeded. The applicant must provide the rates even if the permittee is not proposing to limit potential to emit through production/throughput limitations; however, if the applicant adequately demonstrates the production/throughput rates have not been relied upon to limit potential to emit, these rates will not be reflected as permit conditions.

ii.                  Emission Rates Limited by Maximum Production/Throughput Rates:  Indicate if the hourly or annual emission rates are limited by the proposed maximum hourly or annual production/throughput rates by answering “yes” or “no”.

                        d.                        AIR EMISSIONS INFORMATION:  This information deals directly with the emissions of air pollutants. The applicant must identify and quantify all regulated air pollutants emitted in significant quantities from the source. AP-42 or other EPA recognized documents contain the types of pollutants and approximate emission factors for many types of sources. The applicant must provide supporting calculations for the numbers listed in this section of the emission rate table. The permit application must contain an explanation of the method used to calculate the emission rates. Calculations should reference the source of all data used to determine air emissions. The applicant should provide a manufacturer Material Safety Data Sheet or other manufacturer/vendor data, which indicates the volatile organic compounds (VOC) or hazardous air pollutant (HAP) content in weight percent, and which supports the emission rate calculations, for each material that contains VOCs or HAPs.

i.                    Pollutants:  The applicant must list all regulated air pollutants emitted from the source in this column. The most common pollutants are particulate matter (PM), particulate matter less than 10 microns in diameter (PM10), Particulate matter less than 2.5 microns in diameter (PM2.5), sulfur dioxide (SO2), volatile organic compounds (VOCs), carbon monoxide (CO), and nitrogen oxides (NOx). The applicant should list methane separately from non-methane VOCs. If the applicant emits other air contaminants from the source, such as acetone, ammonia, the applicant must identify and quantify each air contaminant. Designate air contaminants as state regulated pollutants. Do not denote water vapor, carbon dioxide, oxygen, and nitrogen.

Note on PM2.5:  PM2.5 emission are only required only if a specific limit is requested or needed to limit PM2.5. If so, include in this table and provide calculations. Otherwise, specific PM2.5 limits will not be included in the permit for the source.

ii.                  Emissions LB/HR:  Denote the maximum (not average) lb/hr for each pollutant. Round up this value to the nearest tenth or report two significant digits for criteria pollutants and should not be rounded for other pollutants. Enter “0” if the pollutant is not emitted. This value must be consistent with the maximum proposed hourly operating rate. If the maximum is not used, additional record keeping maybe required.

iii.                Emissions TPY:  Denote the total tons per year (tpy) for each pollutant (this value does not always correspond directly to the maximum hourly emission rates. In those cases where the two values do not directly correspond, the supporting calculations should clearly denote the reason for the discrepancy). Round this value up to the nearest tenth or report two significant digits for criteria pollutants. Do not round for other pollutants.  This value may be limited by hours of operation limits or by throughput/production limits. If this value indicates less than continuous operation at maximum operating rates, the permittee should clearly denote in the supporting calculations the factors (i.e. production limits, or hour of operation limits, etc). used to limit the emission rates. The permit will reflect the limits in the permit conditions. If the facility is proposing to operate on a continuous basis, the applicant should calculate the annual emissions based upon 8,760 hours per year of operation. Enter “0” if the pollutant is not emitted.

iv.                Regulations:  The following is a list of state and federal air pollution regulations that may be applicable to a source. Other regulations may also apply.

A.                Standards of Performance for New Stationary Sources (NSPS)

B.                 National Emission Standards for Hazardous Air Pollutants (NESHAP)

C.                 State Implementation Plan (SIP)

D.                Arkansas Air Pollution Control Code (Code)

E.                 Prevention of Significant Deterioration (PSD)

F.                  New Source Review (NSR)

G.                “N/A” if the pollutant is not emitted.

v.                  Control Equipment:  Describe any pollution control equipment (cyclone, baghouse, scrubber, afterburner, etc.). Also, indicate the critical operating parameters of the control equipment (minimum scrubbing liquor flow for scrubbers, minimum temperature for afterburner, etc.). Complete the control equipment operating parameters form for each control device.

vi.                Manufacturer and Model Number:  The manufacturer’s name and model number of the control equipment must be included in the Emission Rate Table.

vii.              Percent Control Efficiency:  Indicate the control efficiency of the air pollution control equipment for the pollutant in question.

44.              HAP Emission Rate Tables:  The applicant must complete a Hazardous Air Pollutant (HAP) Emission Rate Table form for each emission source capable of emitting HAPs. The applicant must complete a separate HAP Emission Rate Table for each emission source. Some listed HAPs are general names for groups of compounds. In such case, list the actual emitted compound.

The emission source number, the year installed or last modified, the process description and SCC should correspond to the information provided on the Emission Rate Table.

Provide the pollutant name and CAS number for each pollutant emitted from the source. The Supplemental Information section contains CAS numbers for HAPs. List all HAPs separately.

Emissions lb/hour. Denote the maximum (not average) emission rate in pounds per hour (lb/hr) for all HAPs. Do not round this value. List emission rates for each HAP separately. Provide supporting calculations for each emission rate. The Supplemental Information section provides example calculations.

Emissions Tons/Year. Denote the total tons per year emitted. Do not round this value. List emission rates for each HAP separately. The hours of operation limitations or throughput/production limitations can limit the emissions. If this value indicates less than continuous operation at maximum operating rates, the permittee should clearly denote in the supporting calculations the factors (i.e. production limits, or hour of operation limits) used to limit the emission rates. The permit will reflect these limits in the permit conditions.

Emission Control Equipment. Describe any pollution control equipment (cyclone, baghouse, scrubber, afterburner, etc.). Also, indicate the critical operating parameters of the control equipment (minimum scrubbing liquor flow for scrubbers, minimum temperature for afterburner). Complete the control equipment operating parameters form for each control device.

% Control Efficiency:  Report the control efficiency used in emission calculation for the air pollution control equipment for the pollutant in question.

45.              Insignificant ActivitiesInsignificant activities are sources that emit pollutants but need not be included as specific sources in the permit with specific conditions. There are two types, Group A and Group B insignificant activities. These can be found in Regulation 18 or Rule 19 (identical). Group A activities are required to be included in the permit application and are evaluated by the Division of Environmental Quality. These will appear in a final permit as a list of Insignificant Activities. Activities listed in Appendix B of these regulations do not generally need to be quantified or included in permit applications.

Group A Insignificant Activities cannot have any Federal requirements, require any recordkeeping or in general have conditions that need to be tracked. The entire source must be insignificant, i.e. you cannot have part of a source’s emissions insignificant and another part subject to permitting.

Attach completed forms for the insignificant activities type at your facility and attach calculations for categories that have a maximum emission rate limit. For the insignificant activities categories that have a maximum emission rate limit, the tpy sum cannot exceed the maximum emission rate.

Equipment Forms

46.              Internal Combustion Engine Summary:  Complete this form for all internal combustion engines that are not considered insignificant. This, in part, will be used to determine applicability of federal rules to the engines.

47.              Control Equipment Operating Parameters:

                         a.                        Identify the emission point number with which the control equipment is associated. This number should correspond to the number provided on the emission rate table.

                        b.                        Provide a separate form for each piece of control equipment.

                         c.                        Provide manufacturer information to support the information provided. This includes not only the manufacturer information for the physical piece of control equipment, but also the manufacturer information on parameters such as scrubber media, required media flow rate, etc.

                        d.                        For control equipment not listed on the Control Equipment Operating Parameters Form, provide any information deemed relevant to the proper operation of the control equipment and provide manufacturer information associated with the control equipment.

                                           e.                        The applicant may supply additional information proposing appropriate monitoring parameters for the subject control equipment. This information is in addition to the required information. This information will be considered during the technical review, but the Division of Environmental Quality will make the final determination for parameters to monitor control equipment based on all information submitted.

48.              Storage Tank SummaryComplete the Storage Tank Information Form for all storage tanks emitting regulated pollutants that are not Insignificant Activities.

49.              Equipment Specifications:  Include engineering drawings, operating parameters, manufacturer’s specifications, and other information as requested for each piece of equipment directly related to the emission of pollutants to the atmosphere. It is not necessary to submit specifications for equipment not relevant to air pollution.

Additional Information

50.              Continuous Emissions Monitoring Systems and Testing:  List all Continuous Emissions Monitoring Systems (CEMS) currently used for determining compliance with regulatory requirements. Additionally, list all existing periodic testing requirements currently used or proposed for determining compliance with regulatory requirements (for example, EPA Method 7E to be used for testing NOx emissions annually).

    OTHER  EXPLAIN

 

#

Yes

No

If yes to any questions, the proposed change most likely does not qualify as a minor mod or de minimis application.

 1  

Are General Information Forms incomplete, missing or unsigned?

 2  

Is the certificate of application missing or not signed by a responsible official?

 3  

Is this a minor mod application and the certificate of compliance missing or not signed by a responsible official?

 4  

Is this a minor mod application and the certification by a responsible official that the proposed minor modification meets the criteria for use of minor mod procedures and a request to use such procedures missing?

 5  

Is any of the following missing that is necessary for, or would be changed by this de minimis/minor modification: emission rate tables, calculations, control equipment operating parameters, process flow diagram, and/or process description?

(if yes, please specify which one(s))

 6  

Is any of the following missing that is necessary for this de minimis/minor modification: a plot plan, a USGS Map and/or a legal description?

(if yes, please specify which one(s))

 7  

Is this a minor mod application and the compliance plan and schedule missing or incomplete?  Compliance plans are only required for Title V applications.  The compliance plan is not the same as the compliance certification.

 8  

Is the application deficient and additional information required?  (if yes specify)

 9  

Is this a minor mod application and the differences between the sum of the proposed permitted rates for all emissions units and the sum of previously permitted emission rates for all units greater than 75 tpy CO; 40 tpy NO2, SO2, or VOC; 25 tpy PM; 15 tpy PM10; 10 tpy direct PM2.5 or 0.5 tpy lead?  See notes below

10                  

Is this a De Minimis application and are the increases in emissions greater than those above, and impacts greater than De Minimis modeling thresholds of: CO 500 ug/m3 8-hour; NO2 10 ug/m3 annual; PM10 8 ug/m3 24-hour; PM2.5 2 ug/m3 24-hour; SO2 18 ug/m3 24-hour; Lead 0.1 ug/m3 3-month?  This would be in lieu of the tpy De Minimis limits.  Normally this demonstration would need to be submitted by the applicant.

11                  

Would the proposed change involve an increase in the permitted emission rates without a corresponding physical change or change in the method of operation at the source?  The source must actually make a modification.  They cannot fail a stack test and ask for their emission limit to be raised through the Minor Mod/De Minimis process.  An increase in production over permitted levels is a change in the method of operation and is eligible for Minor Mod/De Minimis

12                  

Would the proposed change result in a violation of the Clean Air Act? It is unlikely that any modification which meets the other change requirements will violate any provision of the CAA.

13                  

Is the facility major for PSD, is the project considered a “modification” under the PSD definition and will there be a “significant emission increase” in emissions as determined by PSD regulations.   Are all three of these items true?   See 40 CFR 52.21 for details.

14                  

Would the change require a Title I netting procedure to determine eligibilityThis is when all contemporaneous increases and decreases are considered in evaluating if PSD review is required.  This is not the same as calculating the net change in emissions at the emission source.

15                  

Would the proposed change seek to change a case-by-case determination of an emission limitation established pursuant to BACT, 112(g), 112(i)(5), 112(j), or 111(d) of the Clean Air Act?

16                  

Would the proposed change violate provisions of Rule 19?

17                  

Would the proposal change a permit term, condition, or limit that a source has assumed to avoid an applicable requirement to which the source would otherwise be subject?  If someone takes a limit to stay out of PSD, Title V, or a MACT, they cannot change the limit through the Minor Mod/De Minimis change procedures

18                  

Would the proposed change be a significant change or relaxation to existing testing, monitoring, reporting, or recordkeeping requirements? Determination of a significant change will be made on a case-by-case basis.  In general, this should be done by determining why the existing monitoring, testing, or reporting was required and deciding if the new proposal will accomplish the same result.  It should be the applicant's responsibility to demonstrate that the proposed change is not significant.

19                  

Is more than minimal judgment required? In general, the following situations will require more than minimal judgment to determine eligibility:

·      If a facility does not pass the PAER or the PAIL,

·      If more than standard (i.e. AERMOD) modeling is required,

·      If previous modeling indicates the facility is already within 95% of the NAAQS,

·      If there are serious concerns about the emission rate estimates which cannot be resolved.

20                  

Is the Minor Mod/De Minimis part of a larger change at the source or multiple applications that would otherwise disqualify the change from Minor Mod/De Minimis approval?

21                  

On the de minimis/minor mod letter response due date, will any of this applicant’s Arkansas facilities have any unpaid past due fees (for any division)? This includes any facilities under the same entity, i.e.  corporation, owner, etc.  Do not deny for this reason until the day of the response due date unless extenuating circumstances. 

 

Detail any approval conditions or reasons for denial in letter

 

Notes on determining emission changes:

·         A new unit will have a “previously permitted emission rate” of zero

·         An unpermitted existing unit at facility will have a “previously permitted emission rate” of zero

·         An Insignificant Activity moving to a permitted source will have a “previously permitted emission rate” as indicated in the permit application, Statement of Basis or other information showing it was insignificant.

·         A permitted unit without an existing emission rate for PM2.5 will have a “previously permitted emission rate” that has the same ratio of PM2.5/PM10 as the unit will have in the modified permit.


 

Supplemental Information

Example Emission Calculations

Note:  These calculations are examples only. The values used in these examples should not be used to prepare your permit application.

Facility:  Wood Furniture Manufacturing Operation

SN-01:         Wood Working Operations - controlled by cyclone

From AP-42 Table 10.4.1:

Emission factor for sander dust from cyclone = 5.0 lb/hr

Emission factor for other wood working operations from cyclone = 2.0 lb/hr

Therefore, for sawing and sanding operations routed to a common cyclone, the particulate matter (wood dust) emission factor is 7.0 lb/hr.

PM/PM10 = 7.0 lb/hr

PM/PM10 = 7.0 lb/hr x 8760 hr/yr x ton/2000 lb = 30.7 tons/yr

The permit applicant wants to limit the hours of operation for this process in order to reduce the annual permitted emissions. The following information is used to determine maximum annual emissions. The wood working operations operate two 8-hour shifts per day and occasionally on Saturdays. The plant closes for two (2) weeks per year for vacation. Based on this information, the maximum operating hours for the wood working processes are 16 hrs/day, 6 days/wk, and 50 wks/yr. However, the wood working processes never operate more than 400 hours per month. The applicant requests the permit to limit operating hours to 400 hours per month for the wood working operations at the plant.

PM/PM10 = 7.0 lb/hr x 400 hr/mo x 12 mo/yr x ton/2000 lb = 16.8 tons/yr

 

SN-02:  Spray Paint Booth

Based on equipment specifications for the paint booth, the throughput capacity is 6 gallons of paint per hour. Two enamel coatings and a clear coat are applied (at different times) in this booth. The VOC content of the coatings are indicated in the Physical Data section of the MSDS in “Percent Volatile by Volume.” In order to perform the VOC calculations the percent volatile by weight must be obtained from the manufacturer of the coatings. The percent volatile by weight of the black enamel coating as stated in the manufacturer’s additional information is 70%. The percent volatile by weight of the white enamel coating as stated in the manufacturer’s additional information is 66%. The percent volatile by weight of the clear coat as stated in the manufacturer’s additional information is 74%. In order to have maximum flexibility, the applicant assumes that each paint is sprayed at the maximum throughput capacity of 6 gallons per hour rate to determine the “Worst Case” hourly emission rate for each Hazardous Air Pollutant (HAP). Based on historic data, the applicant knows that no more than 750 gallons of paint are applied monthly. The applicant requests to be limited to 750 gallons per month of paint. All information below can be found in the Hazardous Ingredients section, the Physical Data section, or the manufacturer’s attachment to the MSDS sheets provided below.

SN-03:  Drying Oven

A 15 million Btu/hr (MMBtu/hr) natural gas fired drying oven is used to dry and cure the paints after application in the spray paint booth. Natural gas has a fuel heat value of approximately 1000 scf/MMBtu. From AP-42 Tables 1.4-1, 1.4-2, and 1.4-3, the emission factors for natural gas combustion from sources <100 million Btu/hr heat input are:

Emission factor for PM is 7.6 lb/106 scf of natural gas.

Emission factor for SO2 is 0.6 lb/106 scf of natural gas.

Emission factor for VOC is 5.5 lb/106 scf of natural gas.

Emission factor for CO is 84 lb/106 scf of natural gas.

Emission factor for NOx is 100 lb/106 scf of natural gas.

PM/PM10 = 15 MMBtu/hr x 1000 scf/MMBtu x 7.6 lb/MM scf = 0.2 lb/hr

PM/PM10 = 0.2 lb/hr x 8760 hr/yr x ton/2000 lb = 0.9 tons/yr

 

SO2 = 15 MMBtu/hr x 1000 scf/MMBtu x 0.6 lb/MM scf = 0.01 lb/hr (Round to 0.1 lb/hr)

SO2 = 0.1 lb/hr x 8760 hr/yr x ton/2000 lb = 0.5 tons/yr

 

VOC = 15 MMBtu/hr x 1000 scf/MMBtu x 5.5 lb/MM scf = 0.1 lb/hr

VOC = 0.1 lb/hr x 8760 hr/yr x ton/2000 lb = 0.5 tons/yr

 

CO = 15 MMBtu/hr x 1000 scf/MMBtu x 84 lb/MM scf = 1.3 lb/hr

CO = 1.3 lb/hr x 8760 hr/yr x ton/2000 lb = 5.7 tons/yr

 

NOx = 15 MMBtu/hr x 1000 scf/MMBtu x 100 lb/MM scf = 1.5 lb/hr

NOx = 1.5 lb/hr x 8760 hr/yr x ton/2000 lb = 6.6 tons/yr

1X'CN where X'= H' or any other group where a formal dissociation may occur.  For example KCN or Ca(CN)2.

2Includes mono- and diethers of ethylene glycol, diethylene glycol and triethylene glycol R-(OCH2CH)n-OR' where

n = 1, 2, or 3

R = alkyl C7 or less; or

R = phenyl or alkyl substituted phenyl;

Glycol Ethers

On November 21, 2003 (68FR65648), the EPA proposed to remove the compound ethylene glycol monobutyl ether (EGBE) (2-Butoxyethanol) (Chemical Abstract Service (CAS) No. 111-76-2) from the group of glycol ethers. On November 29, 2004 (69FR69320) this proposal was made final.

On January 12, 1999 (64FR1780), the EPA proposed to modify the definition of glycol ethers to exclude surfactant alcohol ethoxylates and their derivatives (SAED). On August 2, 2000 (65FR47342), the EPA published the final action. This action deletes each individual compound in a group called the surfactant alcohol ethoxylates and their derivatives (SAED) from the glycol ethers category in the list of hazardous air pollutants (HAP) established by section 112(b)(1) of the Clean Air Act (CAA). Under section 112(b)(3)(D) of the CAA, EPA may delete specific substances from certain listed categories, including glycol ethers. To implement this action, EPA is revising the definition of glycol ethers to exclude the deleted compounds.

Insignificant Activities List

The following types of activities or emissions are deemed insignificant on the basis of size, emission rate, production rate, or activity. Certain of these listed activities include qualifying statements intended to exclude many similar activities. By such listing, the Division of Environmental Quality exempts certain sources or types of sources from the requirements to obtain a permit or plan under this regulation. Listing in this part has no effect on any other law to which the activity may be subject. Any activity for which a state or federal applicable requirement applies (such as NSPS, NESHAP, or MACT) is not insignificant, even if this activity meets the criteria below.

Group A

The following emission units, operations, or activities must either be listed as insignificant or included in the permit application as sources to be permitted. The listing of insignificant sources does not necessarily mean that the emissions from these sources must be quantified.

1.                  Fuel burning equipment with a design rate less than 10 MMBtu per hour, provided that the aggregate air pollutant specific emissions from all such units listed as insignificant do not exceed 5 tons per year (tpy) of any combination of HAPs, 75,000 tpy carbon dioxide, and 10 tpy of any other air pollutant.

2.                  Storage tanks less than or equal to 250 gallons storing organic liquids having a true vapor pressure less than or equal to 3.5 psia, provided that the aggregate air pollutant specific emissions from all such liquid storage tanks listed as insignificant do not exceed 5 tpy of any combination of HAPs and 10 tpy of any other air pollutant.

3.                  Storage tanks less than or equal to 10,000 gallons storing organic liquids having a true vapor pressure less than or equal to 0.5 psia, provided that the aggregate air pollutant specific emissions from all such liquid storage tanks listed as insignificant do not exceed 5 tpy of any combination of HAPs and 10 tpy of any other air pollutant.
