Description:

Stations 1-6 transport natural gas via pipeline from the various production wells in the area to a Central Delivery Point (CDP) or a natural gas processing plant located off the Fort Berthold Indian Reservation. The typical process flow at each station is as follows.

Natural gas first enters the compressor station through a gas system receiver, where the natural gas passes through a slug catcher to "knock out" excess liquids. Further removal of liquids from the natural gas is carried out by a filter separator, after which the gas is routed to the screw-type compressor unit(s) for compression. The compressor units each consist of an inlet filter separator, a compressor, a finned-fan heat exchanger and a natural gas-fired engine to power the compressor. Gas entering an individual compressor unit first passes through the filter separator to further remove liquids from the gas stream before compression, after which the gas is compressed by the compressor. Compressed gas is then routed to a splitter, with most of the gas routed to the gas pipeline exiting the station and the remainder routed to a fuel gas coalescer. Gas from the fuel gas coalescer will be routed to and combusted by individual screw-type compressor engines and/or natural gas-fired electrical generator engines designed to provide primary or backup power to the station.

Condensate and water removed from the natural gas via the slug catcher and/or filter separator(s) is
routed to on-site storage tanks. Truck load out area(s) are used to load tanker trucks with water and
condensate for transit offsite. Furthermore, the design of Stations 1-6 does not allow crude oil to be handled in the emissions units; rather, crude oil remains in underground pipelines located at or near Stations 1-6 for further transport to the CDP.

In addition, a condensate stabilizer system consisting of a condensate stabilizer tower and natural gas-fired heater is used at Station 2. Raw condensate is piped from the inlet separation equipment to the condensate stabilizer tower. Light hydrocarbon components flash off and rise to the top of the tower as vapor that is transferred to the gas gathering line. Heavier hydrocarbons fall to the bottom of the tower as liquid that is transferred into the oil gathering line. Process heat is provided to the system by a standard natural gas-fired burner rated at 5.0 million British thermal units per hour (MMBtu/hr). The system is a completely closed system and, other than the combustion emissions from the burner, does not have any process vents that are vented to atmosphere.

The design of each station is relatively similar and involves similar equipment. Bypass valves allow the
routing of the primary natural gas pipelines past an individual station and on down the pipeline to the next station or to a pipeline that travels off of the Fort Berthold Indian Reservation.

In order to provide Arrow with the flexibility to relocate emissions units (i.e., compressors, pumps and
electrical generator engines) between the various locations, the synthetic Minor New Source Review Permit (MNSR) (#SMNSR-TAT-000367-2021.005) limits the maximum natural gas-fired reciprocating internal combustion engine (RICE) horsepower (hp) to 9,100 at an individual station.

       The Permittee shall install temperature sensing devices (e.g., thermocouple or resistance temperature detectors) before the catalytic control system on each engine in order to continuously monitor the exhaust temperature to the inlet of the catalyst bed. Each
            temperature sensing device shall be calibrated and operated by the Permittee according to manufacturer specifications.

       Except during startups, which shall not exceed 30 minutes, the engine exhaust temperature of each engine, at the inlet to the catalyst bed, shall be maintained at all times the engines operate with an inlet temperature of at least 450 °F and no more than
	1,350 °F.

       If the exhaust temperature at the inlet to the catalyst bed deviates from the ranges required by this permit, then the Permittee shall take the following actions:

             Immediately upon determining a deviation of the inlet temperature, corrective action shall be taken on that engine to assess performance problems and/or tuning issues and the catalytic control system shall be inspected for possible damage and problems affecting catalyst effectiveness (including, but not limited to, plugging, fouling, destruction or poisoning of the catalyst bed). Investigation may include monitoring of NOX, CO, VOC and/or CH2O emissions to ensure the catalytic control system is functioning and testing the temperature sensing devices;
             If the problem can be corrected by following the engine and/or the catalytic control system manufacturer recommended procedures (or equivalent procedures provided they bring the inlet temperature to the catalyst bed back within the acceptable temperature range), then the Permittee shall correct the problem within 24 hours of inspecting the engine and catalyst control system;
             If the problem cannot be corrected using the manufacturer's recommended procedures, then the affected engine shall cease operating immediately and shall not be returned to routine service until the inlet temperature to the catalyst bed is measured and found to be within the acceptable temperature range for that engine. Corrective action may include removal and cleaning of the catalyst according to manufacturer methods, replacement of the catalyst or replacement of the catalytic control system; and
             The Permittee's completion of any or all of these actions shall not constitute, nor qualify as, an exemption from any other emission limits in this permit.

       The Permittee shall monitor the pressure drop across each catalyst bed during normal operations on a monthly basis.

       During operation, the pressure drop across the catalyst bed on each engine shall be maintained to within 2 inches of water from the baseline pressure drop reading taken during the most recent performance test.

       If the pressure drop exceeds 2 inches of water from the baseline pressure drop reading taken during the most recent performance test, then the following actions shall be taken by the Permittee:

 Immediately upon determining a deviation of the pressure drop, corrective action shall be taken to assess performance problems for possible damage and problems affecting catalytic control systems effectiveness (including, but not limited to, plugging, fouling, destruction or poisoning of the catalyst in the catalyst bed). Investigation may include monitoring of NOX, CO, VOC and/or CH2O emissions to ensure the catalytic control system is functioning and testing the pressure transducers. If the cause is determined to be the catalyst, then the catalyst shall be inspected and cleaned or replaced, if necessary;
 If the problem can be corrected by following the engine and/or the catalytic control system's manufacturer recommended procedures, or equivalent procedures provided they bring the pressure drop across the catalyst bed back to within 2 inches of water from the baseline pressure drop reading taken during the most recent performance test, then the Permittee shall correct the problem within 24 hours of inspecting the catalytic control system;
 If the problem cannot be corrected using manufacturer recommended procedures, then the affected engine shall cease operating immediately and shall not be returned to routine service until the pressure drop across the catalyst bed is measured and found to be within the acceptable pressure drop range. Corrective action may include removal and cleaning of the catalyst according to manufacturer methods, replacement of the catalyst or replacement of the catalytic control system; and
 The Permittee's completion of any or all of these actions shall not constitute, nor qualify as, an exemption from any other emission limits in this permit.

             Submit the analyzer specifications and monitoring protocol to the EPA for approval at least 45 calendar days prior to the date of initial portable analyzer monitoring; and
             Commence monitoring for NOX and CO emissions during the first calendar quarter following the submittal of the initial performance test results for NOX and CO emissions to the EPA.

       For any one engine: If the results of two consecutive quarterly portable analyzer measurements are less than 80% of the CO emission limit, the required test frequency shall change from quarterly to semi-annual. If the results of two consecutive semi-annual portable analyzer measurements are less than 80% of the CO emission limit, the required monitoring frequency shall change from semi-annual to annual. If the results of any
            single portable analyzer measurement are more than 80% of the CO emission limit, the required test frequency shall change back to quarterly.

       For any one engine: If the results of two consecutive quarterly portable analyzer measurements are less than 80% of the NOX emission limit, the required test frequency shall change from quarterly to semi-annual. If the results of two consecutive semi-annual portable analyzer measurements are less than 80% of the NOX emission limit, the required monitoring frequency shall change from semi-annual to annual.

 Emissions from equipment leaks shall be determined by assuming 8,760 hours of operation in a year and with maximum leakage of all components. The annual VOC emissions rate from equipment leaks shall be no more than 9.4 tpy.

 Requirements for Minimizing Fugitive Dust

 Work Practice and Operational Requirements

       The Permittee shall take all reasonable precautions to prevent fugitive dust emissions at each station and shall construct, maintain and operate each station to minimize fugitive dust emissions. Reasonable precautions include, but are not limited to the following:

             Use, where possible, of water or chemicals for control of dust during construction and operations, grading of roads or clearing of land;
             Application of asphalt, water or other suitable chemicals on unpaved roads, materials stockpiles and other surfaces, located at the facilities, that can create airborne dust;
             The prompt removal from paved surfaces, located at the station, of earth or other material that does or may become airborne; or
             Restricting vehicle speeds.

       The Permittee shall prepare and implement a written fugitive dust emission prevention plan, approved by the EPA, that specifies the reasonable precautions to be taken and the procedures to be followed to prevent fugitive dust emissions.

 Monitoring Requirements

       The Permittee shall survey the station during construction and operation to determine if there are obvious visible dust plumes. This survey must be done at a minimum once per week in all active areas and during daylight hours.

       The Permittee shall document the results of the survey, including the date and time of the survey, identification of the cause of any visible dust plumes observed and the precautions taken to prevent continued fugitive dust emissions.

 Recordkeeping Requirements

      The Permittee shall maintain records for 5 years that document the fugitive dust prevention plan, the periodic surveys, and the reasonable precautions that were taken to prevent fugitive dust emissions.

 Facility-Wide Requirements [40 CFR 71.6(a)(1)]

Conditions in this section of this permit apply to all emissions units located at the source, including any units not specifically listed in this permit.

 Recordkeeping Requirements [40 CFR 71.6(a)(3)(ii)]

The Permittee shall comply with the following generally applicable recordkeeping requirements:

 If the Permittee determines that his or her stationary source that emits (or has the potential to emit, without considering controls) one or more HAPs is not subject to a relevant standard or other requirement established under 40 CFR part 63, the Permittee shall keep a record of the applicability determination on site at the source for a period of 5 years after the determination, or until the source changes its operations to become an affected source, whichever comes first. The record of the applicability determination shall include an analysis (or other information) that demonstrates why the Permittee believes the source is unaffected (e.g., because the source is an area source). [40 CFR 63.10(b)(3)]

 Records shall be kept of off permit changes, as required by the Off Permit Changes section of this permit.

 Reporting Requirements [40 CFR 71.6(a)(3)(iii)]
1. 	The Permittee shall submit to the EPA all reports of any required monitoring under this permit semiannually. The first report shall cover the period from the effective date of this permit through December 31, 2021. Thereafter, the report shall be submitted semi-annually, by April 1[st] and October 1[st] of each year. The report due on April 1[st] shall cover the 6-month period ending on the last day of December before the report is due. The report due on October 1[st] shall cover the 6-month period ending on the last day of June before the report is due. All instances of deviations from permit requirements shall be clearly identified in such reports. All required reports shall be certified by a responsible official consistent with the Submissions section of this permit.

To help Part 71 Permittees meet reporting responsibilities, the EPA has developed a form "SIXMON" for 6-month monitoring reports. The form may be found on the EPA's website at: https://www.epa.gov/title-v-operating-permits/epa-issued-operating-permits]

2. 	"Deviation" means any situation in which an emissions unit fails to meet a permit term or condition. A deviation is not always a violation. A deviation can be determined by observation or through review of data obtained from any testing, monitoring, or recordkeeping established in accordance with §71.6(a)(3)(i) and (a)(3)(ii). For a situation lasting more than 24 hours which constitutes a deviation, each 24-hour period is considered a separate deviation. Included in the meaning of deviation are any of the following:

 A situation where emissions exceed an emission limitation or standard;

 A situation where process or emissions control device parameter values indicate that an emission limitation or standard has not been met; or

 A situation in which observations or data collected demonstrate noncompliance with an emission limitation or standard or any work practice or operating condition required by the permit.

3. 	The Permittee shall promptly report to the EPA deviations from permit requirements, including those attributable to upset conditions as defined in this permit, the probable cause of such deviations, and any corrective actions or preventive measures taken. "Prompt" is defined as follows:

      (a)	Any definition of "prompt" or a specific time frame for reporting deviations provided in an underlying applicable requirement as identified in this permit.

      (b)	Where the underlying applicable requirement fails to address the time frame for reporting deviations, reports of deviations will be submitted based on the following schedule:

             For emissions of a HAP or a toxic air pollutant (as identified in the applicable regulation) that continue for more than an hour in excess of permit requirements, the report shall be made within 24 hours of the occurrence.
             For emissions of any regulated air pollutant, excluding a HAP or a toxic air pollutant that continues for more than 2 hours in excess of permit requirements, the report shall be made within 48 hours.
             For all other deviations from permit requirements, the report shall be submitted with the semi-annual monitoring report.
      (c)	If any of the conditions in (i) or (ii) of paragraph (b) above are met, the Permittee shall notify the EPA by telephone (1-800-227-6312), facsimile<PHONE_NUMBER>), or by email to<EMAIL_ADDRESS>based on the timetables listed above. [Notification shall specify that this notification is a deviation report for a Part 71 permit]. A written notice, certified consistent with the Submissions section of this permit shall be submitted within ten working days of the occurrence. All deviations reported under this section shall also be identified in the 6-month report required under Condition 1 in this section of this permit.

[Explanatory note: To help Part 71 Permittees meet reporting responsibilities, the EPA has developed a form "PDR" for prompt deviation reporting. The form may be found on the EPA's website at: https://www.epa.gov/title-v-operating-permits/epa-issued-operating-permits]

 General Provisions

 Annual Fee Payment [40 CFR 71.9]

 The Permittee shall pay an annual permit fee in accordance with the procedures outlined below.

 The Permittee shall pay the annual permit fee each year no later than April 1[st]. The fee shall cover the previous calendar year.

 The fee payment shall be in United States currency and shall be paid by money order, bank draft, certified check, corporate check, or electronic funds transfer payable to the order of the U.S. Environmental Protection Agency.

 The Permittee shall send fee payment and a completed fee filing form to:

      U.S. Environmental Protection Agency
      OCFO/OC/ACAD/FCB
      Attn: Collections Team
      1300 Pennsylvania Ave NW
      Mail Code 2733R
      Washington, D.C.  20004

      The Permittee shall send an updated fee calculation worksheet form and a photocopy of each fee payment check (or other confirmation of actual fee paid) submitted annually by the same deadline as required for fee payment to the address listed in the Submissions section of this permit.

[Explanatory note: The fee filing form "FF" and the fee calculation worksheet form "FEE" may be found on the EPA's website at: https://www.epa.gov/title-v-operating-permits/epa-issued-operating-permits]

 Basis for calculating annual fee:

 The annual emissions fee shall be calculated by multiplying the total tons of actual emissions of all "regulated pollutants (for fee calculation)" emitted from the source by the presumptive emissions fee (in dollars per ton) in effect at the time of calculation.
             "Actual emissions" means the actual rate of emissions in tpy of any regulated pollutant (for fee calculation) emitted from a Part 71 source over the preceding calendar year. Actual emissions shall be calculated using each emissions unit's actual operating hours, production rates, in-place control equipment, and types of materials processed, stored, or combusted during the preceding calendar year.
             Actual emissions shall be computed using methods required by the permit for determining compliance, such as monitoring or source testing data.
             If actual emissions cannot be determined using the compliance methods in the permit, the Permittee shall use other federally recognized procedures.

[Explanatory note: The presumptive fee amount is revised each calendar year to account for inflation, and it is available from the EPA prior to the start of each calendar year.]

 The annual emissions fee shall be increased by a greenhouse gas (GHG) fee adjustment for any source that has initiated an activity listed in table at §71.9(c)(8) since the fee was last paid. The GHG fee adjustment shall be equal to the set fee provided in the table at §71.9(c)(8) for each activity that has been initiated since the fee was last paid.

 The Permittee shall exclude the following emissions from the calculation of fees:

             The amount of actual emissions of each regulated pollutant (for fee calculation) that the source emits in excess of 4,000 tpy;
             Actual emissions of any regulated pollutant (for fee calculation) already included in the fee calculation; and
             The quantity of actual emissions (for fee calculation) of insignificant activities [defined in 40 CFR 71.5(c)(11)(i)] or of insignificant emissions levels from emissions at the source identified in the Permittee's application pursuant to 40 CFR 71.5(c)(11)(ii).

 Fee calculation worksheets shall be certified as to truth, accuracy, and completeness by a responsible official.

[Explanatory note: The fee calculation worksheet form already incorporates a section to help you meet this responsibility.]

 The Permittee shall retain fee calculation worksheets and other emissions-related data used to determine fee payment for 5 years following submittal of fee payment. [Emission-related data include, for example, emissions-related forms provided by the EPA and used by the Permittee for fee calculation purposes, emissions-related spreadsheets, and emissions-related data, such as records of emissions monitoring data and related support information required to be kept in accordance with 40 CFR 71.6(a)(3)(ii).]

 Failure of the Permittee to pay fees in a timely manner shall subject the Permittee to assessment of penalties and interest in accordance with 40 CFR 71.9(l).

 When notified by the EPA of underpayment of fees, the Permittee shall remit full payment within 30 days of receipt of notification.

 A Permittee who thinks an EPA-assessed fee is in error and who wishes to challenge such fee, shall provide a written explanation of the alleged error to the EPA along with full payment of the EPA assessed fee.

 Annual Emissions Inventory [40 CFR 71.9(h)(1) and (2)]

 The Permittee shall submit an annual emissions report of its actual emissions for both criteria pollutants and regulated HAPs for this source for the preceding calendar year for fee assessment purposes. The annual emissions report shall be certified by a responsible official and shall be submitted each year to the EPA by April 1[st].

 The annual emissions report shall be submitted to the EPA at the address listed in the Submissions section of this permit.

[Explanatory note: An annual emissions report, required at the same time as the fee calculation worksheet by 40 CFR 71.9(h), has been incorporated into the fee calculation worksheet form as a convenience.]

 Compliance Requirements [40 CFR 71.6(a)(6), Section 113(a) and 113(e)(1) of the CAA, and 40 CFR 51.212, 52.12, 52.33, 60.11(g) and 61.12]

 Compliance with the Permit

       The Permittee must comply with all conditions of this Part 71 permit. Any permit noncompliance constitutes a violation of the CAA and is grounds for enforcement action; for permit termination, revocation and reissuance, or modification; or for denial of a permit renewal application.

       It shall not be a defense for a Permittee in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the conditions of this permit.

       For the purpose of submitting compliance certifications in accordance with §71.6(c)(5), or establishing whether or not a person has violated or is in violation of any requirement of this permit, nothing shall preclude the use, including the exclusive use, of any credible evidence or information, relevant to whether a source would have been in compliance with applicable requirements if the appropriate performance or compliance test or procedure had been performed.

 Compliance Schedule [40 CFR 71.5(c)(8)(iii)]

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

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

3.	Compliance Certifications [40 CFR 71.6(c)(5)]

       The Permittee shall submit to the EPA a certification of compliance with permit terms and conditions, including emission limitations, standards, or work practices annually by
            April 1[st], and shall cover the same 12-month period as the two consecutive semi-annual monitoring reports.

[Explanatory note: To help Part 71 Permittees meet reporting responsibilities, the EPA has developed a reporting form for annual compliance certifications. The form may be found on the EPA's website at: https://www.epa.gov/title-v-operating-permits/epa-issued-operating-permits ]

       The compliance certification shall be certified as to truth, accuracy, and completeness by a responsible official consistent with 40 CFR 71.5(d).

       The certification shall include the following:

             Identification of each permit term or condition that is the basis of the certification;
             The identification of the method(s) or other means used for determining the compliance status of each term and condition during the certification period, and whether such methods or other means provide continuous or intermittent data. Such methods and other means shall include, at a minimum, the methods and means required in this permit. If necessary, the Permittee also shall identify any other material information that must be included in the certification to comply with Section 113(c)(2) of the CAA, which prohibits knowingly making a false certification or omitting material information;
             The status of compliance with each term and condition of the permit for the period covered by the certification based on the method or means designated in (ii) above. The certification shall identify each deviation and take it into account in the compliance certification;
             Such other facts as the EPA may require to determine the compliance status of the source; and
             Whether compliance with each permit term was continuous or intermittent.

 Duty to Provide and Supplement Information [40 CFR 71.6(a)(6)(v), 71.5(a)(3), and 71.5(b)]

 The Permittee shall furnish to the EPA, within a reasonable time, any information that the EPA may request in writing to determine whether cause exists for modifying, revoking, and reissuing, or terminating the permit, or to determine compliance with the permit. Upon request, the Permittee shall also furnish to the EPA copies of records that are required to be kept pursuant to the terms of the permit, including information claimed to be confidential. Information claimed to be confidential must be accompanied by a claim of confidentiality according to the provisions of 40 CFR part 2, subpart B.

 The Permittee, upon becoming aware that any relevant facts were omitted or incorrect information was submitted in the permit application, shall promptly submit such supplementary facts or corrected information. In addition, a Permittee shall provide additional information as necessary to address any requirements that become applicable after the date a complete application is filed, but prior to release of a draft permit.

 Submissions [40 CFR 71.5(d), 71.6(c)(1) and 71.9(h)(2)]

 Any document (application form, report, compliance certification, etc.) required to be submitted under this permit shall be certified by a responsible official as to truth, accuracy, and completeness. Such certifications shall state that based on information and belief formed after reasonable inquiry, the statements and information in the document are true, accurate, and complete.

[Explanatory note: the EPA has developed a reporting form "CTAC" for certifying truth, accuracy and completeness of Part 71 submissions. The form may be found on the EPA's website at: https://www.epa.gov/title-v-operating-permits/epa-issued-operating-permits]

      All fee calculation worksheets and applications for renewals and permit modifications shall be submitted to:

            Part 71 Permit Contact, Air and Radiation Division, 8ARD-PM
            U.S. Environmental Protection Agency, Region 8

 CEDRI now has the capability to receive Part 71 documents that require certification by a responsible official. Specifically, we have added a form to CEDRI under "State/Local/Tribe Rule or Permit." The form allows for the user to submit four types of documents under Part 71: Clean Air Act 502(b)(10) change notification, a semi-annual monitoring report, a deviation notification, and a Title V application. The EPA is in the midst of announcing this new capability. The use of CEDRI for submitting these reports will not be mandatory but just provides an additional option. The job aide for how to submit reports in general can be found here: https://www3.epa.gov/ttn/chief/cedri/Create_Reports_Job_Aide.pdf.

 Severability Clause [40 CFR 71.6(a)(5)]

The provisions of this permit are severable, and in the event of any challenge to any portion of this permit, or if any portion is held invalid, the remaining permit conditions shall remain valid and in force.

 Permit Actions [40 CFR 71.6(a)(6)(iii)]

This permit may be modified, revoked, reopened, and reissued, or terminated for cause. The filing of a request by the Permittee for a permit modification, revocation and reissuance, or termination, or of a notification of planned changes or anticipated noncompliance does not stay any permit condition.

 Administrative Permit Amendments [40 CFR 71.7(d)]

The Permittee may request the use of administrative permit amendment procedures for a permit revision that:

 Corrects typographical errors;

 Identifies a change in the name, address, or phone number of any person identified in the permit, or provides a similar minor administrative change at the source;

 Requires more frequent monitoring or reporting by the Permittee;

 Allows for a change in ownership or operational control of a source where the EPA determines that no other change in the permit is necessary, provided that a written agreement containing a specific date for transfer of permit responsibility, coverage, and liability between the current and new Permittee has been submitted to the EPA;

 Incorporates into the Part 71 permit the requirements from preconstruction review permits authorized under an EPA-approved program, provided that such a program meets procedural requirements substantially equivalent to the requirements of 40 CFR 71.7 and 71.8 that would be applicable to the change if it were subject to review as a permit modification, and compliance requirements substantially equivalent to those contained in 40 CFR 71.6; or

 Incorporates any other type of change which the EPA has determined to be similar to those listed in (1) through (5) above.

[Note to Permittee: If 1 through 5 above do not apply, please contact the EPA for a determination of similarity prior to submitting your request for an administrative permit amendment under this provision.]

 Minor Permit Modifications [40 CFR 71.7(e)(1)]

 The Permittee may request the use of minor permit modification procedures only for those modifications that:

       Do not violate any applicable requirement;

       Do not involve significant changes to existing monitoring, reporting, or recordkeeping requirements in the permit;

       Do not require or change a case-by-case determination of an emission limitation or other standard, or a source-specific determination for temporary sources of ambient impacts, or a visibility or increment analysis;

       Do not seek to establish or change a permit term or condition for which there is no corresponding underlying applicable requirement and that the source has assumed to avoid an applicable requirement to which the source would otherwise be subject. Such terms and conditions include:

             A federally enforceable emissions cap assumed to avoid classification as a modification under any provision of Title I; and
             An alternative emissions limit approved pursuant to regulations promulgated under Section 112(i)(5) of the CAA;

       Are not modifications under any provision of Title I of the CAA; and

       Are not required to be processed as a significant modification.

 Notwithstanding the list of changes ineligible for minor permit modification procedures in 1 above, minor permit modification procedures may be used for permit modifications involving the use of economic incentives, marketable permits, emissions trading, and other similar approaches, to the extent that such minor permit modification procedures are explicitly provided for in an applicable implementation plan or in applicable requirements promulgated by the EPA.

 An application requesting the use of minor permit modification procedures shall meet the requirements of 40 CFR 71.5(c) and shall include the following:

       A description of the change, the emissions resulting from the change, and any new applicable requirements that will apply if the change occurs;

       The source's suggested draft permit;

       Certification by a responsible official, consistent with 40 CFR 71.5(d), that the proposed modification meets the criteria for use of minor permit modification procedures and a request that such procedures be used; and

      (d)       Completed forms for the permitting authority to use to notify affected states as required under 40 CFR 71.8.

 The source may make the change proposed in its minor permit modification application immediately after it files such application. After the source makes the change allowed by the preceding sentence, and until the permitting authority takes any of the actions authorized by     40 CFR 71.7(e)(1)(iv)(A) through (C), the source must comply with both the applicable requirements governing the change and the proposed permit terms and conditions. During this time period, the source need not comply with the existing permit terms and conditions it seeks to modify. However, if the source fails to comply with its proposed permit terms and conditions during this time period, the existing permit terms and conditions it seeks to modify may be enforced against it.

 The permit shield under 40 CFR 71.6(f) may not extend to minor permit modifications.

 Significant Permit Modifications [40 CFR 71.7(e)(3), 71.8(d), and 71.5(a)(2)]

 The Permittee must request the use of significant permit modification procedures for those modifications that:

       Do not qualify as minor permit modifications or as administrative amendments;

       Are significant changes in existing monitoring permit terms or conditions; or

       Are relaxations of reporting or recordkeeping permit terms or conditions.

 Nothing herein shall be construed to preclude the Permittee from making changes consistent with Part 71 that would render existing permit compliance terms and conditions irrelevant.

 Permittees must meet all requirements of Part 71 for applications, public participation, and review by affected states and tribes for significant permit modifications. For the application to be determined complete, the Permittee must supply all information that is required by                    40 CFR 71.5(c) for permit issuance and renewal, but only that information that is related to the proposed change.

 Reopening for Cause [40 CFR 71.7(f)]

The permit may be reopened and revised prior to expiration under any of the following circumstances:

 Additional applicable requirements under the CAA become applicable to a major Part 71 source with a remaining permit term of 3 or more years. Such a reopening shall be completed no later than 18 months after promulgation of the applicable requirement. No such reopening is required if the effective date of the requirement is later than the date on which the permit is due to expire, unless the original permit or any of its terms and conditions have been extended pursuant to       40 CFR 71.7(c)(3);

 Additional requirements (including excess emissions requirements) become applicable to an affected source under the acid rain program. Upon approval by the Administrator, excess emissions offset plans shall be deemed to be incorporated into the permit;

 The EPA determines that the permit contains a material mistake or that inaccurate statements were made in establishing the emissions standards or other terms or conditions of the permit; or

 The EPA determines that the permit must be revised or revoked to assure compliance with the applicable requirements.

 Property Rights [40 CFR 71.6(a)(6)(iv)]

This permit does not convey any property rights of any sort, or any exclusive privilege.

 Inspection and Entry [40 CFR 71.6(c)(2)]

 Upon presentation of credentials and other documents as may be required by law, the Permittee shall allow the EPA or an authorized representative to perform the following:

 Enter upon the Permittee's premises where a Part 71 source is located or emissions-related activity is conducted, or where records must be kept under the conditions of the permit;

 Have access to and copy, at reasonable times, any records that must be kept under the conditions of the permit;

 Inspect at reasonable times any facilities, equipment (including monitoring and air pollution control equipment), practices, or operations regulated or required under the permit; and
5.	As authorized by the CAA, sample or monitor at reasonable times substances or parameters for the purpose of assuring compliance with the permit or applicable requirements.

 Transfer of Ownership or Operation [40 CFR 71.7(d)(1)(iv)]

A change in ownership or operational control of this source may be treated as an administrative permit amendment if the EPA determines no other change in this permit is necessary and provided that a written agreement containing a specific date for transfer of permit responsibility, coverage, and liability between the current and new Permittee has been submitted to the EPA.

 Off Permit Changes [40 CFR 71.6(a)(12) and 40 CFR 71.6(a)(3)(ii)]

The Permittee is allowed to make certain changes without a permit revision, provided that the following requirements are met, and that all records required by this section are kept for a period of 5 years:

 Each change is not addressed or prohibited by this permit;

 Each change shall meet with all applicable requirements and shall not violate any existing permit term or condition;

 Changes under this provision may not include changes subject to any requirement of 40 CFR parts 72 through 78 or modifications under any provision of Title I of the CAA;

 The Permittee must provide contemporaneous written notice to the EPA of each change, except for changes that qualify as insignificant activities under 40 CFR 71.5(c)(11). The written notice must describe each change, the date of the change, any change in emissions, pollutants emitted, and any applicable requirements that would apply as a result of the change;

 The permit shield does not apply to changes made under this provision;

 The Permittee must keep a record describing all changes that result in emissions of any regulated air pollutant subject to any applicable requirement not otherwise regulated under this permit, and the emissions resulting from those changes;

 The notice shall be kept on site and made available to the EPA on request, in accordance with the general recordkeeping provision of this permit; and

 Submittal of the written notice required above shall not constitute a waiver, exemption, or shield from applicability of any applicable standard or PSD permitting requirements under 40 CFR 52.21 that would be triggered by the change.

 Permit Expiration and Renewal [40 CFR 71.5(a)(1)(iii), 71.5(a)(2), 71.5(c)(5), 71.6(a)(11), 71.7(b), 71.7(c)(1), and 71.7(c)(3)]

 This permit shall expire upon the earlier occurrence of the following events:

       Five (5) years elapse from the date of issuance; or

       The source is issued a 40 CFR part 70 or Part 71 permit under an EPA-approved or delegated permit program.

 Expiration of this permit terminates the Permittee's right to operate unless a timely and complete permit renewal application has been submitted at least 6 months but not more than 18 months prior to the date of expiration of this permit.

 If the Permittee submits a timely and complete permit application for renewal, consistent with 40 CFR 71.5(a)(2), but the EPA has failed to issue or deny the renewal permit, then all the terms and conditions of the permit, including any permit shield granted pursuant to 40 CFR 71.6(f) shall remain in effect until the renewal permit has been issued or denied.

 The Permittee's failure to have a Part 71 permit is not a violation of this part until the EPA takes final action on the permit renewal application. This protection shall cease to apply if, subsequent to the completeness determination, the Permittee fails to submit any additional information identified as being needed to process the application by the deadline specified in writing by the EPA.

 Renewal of this permit is subject to the same procedural requirements that apply to initial permit issuance, including those for public participation, affected state, and tribal review.

 The application for renewal shall include the current permit number, description of permit revisions and off permit changes that occurred during the permit term, any applicable requirements that were promulgated and not incorporated into the permit during the permit term, and other information required by the application form.
