29.  NESHAP Operational Requirements

29.a.  Operation and maintenance requirements [40 CFR 63.6(e)] At all times, including periods of startup, shutdown, and malfunction, the permittee shall operate and maintain any affected source, including associated air pollution control equipment, in a manner consistent with good air pollution control practices for minimizing emissions at least to the levels required by conditions 27 and 28.

29.a.i.  Malfunctions shall be corrected as soon as practicable after their occurrence in accordance with the startup, shutdown, and malfunction plan required in condition 29.c.

29.a.ii.  Operation and maintenance requirements established pursuant to section 112 of the Act are enforceable independent of emissions limitations or other requirements in conditions 26, 27, 28, 46, 47, 65, 82, 90, and 91.

29.a.iii.  Determination of whether acceptable operation and maintenance procedures are being used will be based on information available to the Administrator which may include, but is not limited to, monitoring results, review of operation and maintenance procedures [including the startup, shutdown, and malfunction plan required in condition 29.c], review of operation and maintenance records, and inspection of the source.

29.b.  Corrective action. [63.848(h)] If a monitoring device for a primary control device measures an operating parameter outside the limit(s) established pursuant to condition 46.f or, if visible emissions indicating abnormal operation are observed from the exhaust stack of a control device during a daily inspection, the owner or operator shall initiate the corrective action procedures identified in the startup, shutdown, and malfunction plan within 1 hour. Failure to initiate the corrective action procedures within 1 hour or to take the necessary corrective actions to remedy the problem is a violation.

29.c.  Startup, Shutdown, and Malfunction Plan. [40 CFR 63.6(e)]

29.c.i.  For each affected source, the permittee shall develop and implement a written startup, shutdown, and malfunction plan that describes, in detail, procedures for operating and maintaining the source during periods of startup, shutdown, and malfunction and a program of corrective action for malfunctioning process and air pollution control equipment used to comply with conditions 26, 27, 28, 29, and 65. As required under condition 66.b.i.1, the plan shall identify all routine or otherwise predictable CMS malfunctions. This plan shall be developed by the permittee by the first compliance date in condition 25. The plan shall be considered to be incorporated by reference into this Permit. Changes to the startup, shutdown, and malfunction plan shall be made in accordance with the procedures in condition 29.c. No change that affects only the startup, shutdown, and malfunction plan shall be considered a change, revision or modification to the permit. The purpose of the startup, shutdown, and malfunction plan is to--

29.c.i.1.  Ensure that, at all times, the permittee operates and maintains affected sources, including associated air pollution control equipment, in a manner consistent with good air pollution control practices for minimizing emissions at least to the levels required by conditions 26, 27, 28, and 29;

29.c.i.2.  Ensure that permittee are prepared to correct malfunctions as soon as practicable after their occurrence in order to minimize excess emissions of hazardous air pollutants; and

29.c.i.3.  Reduce the reporting burden associated with periods of startup, shutdown, and malfunction (including corrective action taken to restore malfunctioning process and air pollution control equipment to its normal or usual manner of operation).

29.c.ii.  During periods of startup, shutdown, and malfunction, the permittee shall operate and maintain each affected source (including associated air pollution control equipment) in accordance with the procedures specified in the startup, shutdown, and malfunction plan developed under condition 29.c.i.

29.c.iii.  When actions taken by the permittee during a startup, shutdown, or malfunction (including actions taken to correct a malfunction) are consistent with the procedures specified in the affected source’s startup, shutdown, and malfunction plan, the permittee shall keep records for that event that demonstrate that the procedures specified in the plan were followed. These records may take the form of a “checklist,” or other effective form of recordkeeping, that confirms conformance with the startup, shutdown, and malfunction plan for that event. In addition, the permittee shall keep records of these events as specified in condition 82.a (and elsewhere in 40 CFR part 63), including records of the occurrence and duration of each startup, shutdown, or malfunction of operation and each malfunction of the air pollution control equipment. Furthermore, the permittee shall confirm that actions taken during the relevant reporting period during periods of startup, shutdown, and malfunction were consistent with the affected source’s startup, shutdown and malfunction plan in the semiannual (or more frequent) startup, shutdown, and malfunction report required in condition 91.a.ii.

29.c.iv.  If an action taken by the permittee during a startup, shutdown, or malfunction (including an action taken to correct a malfunction) is not consistent with the procedures specified in the affected source’s startup, shutdown, and malfunction plan, the permittee shall record the actions taken for that event and shall report such actions within 2 working days after commencing actions inconsistent with the plan, followed by a letter within 7 working days after the end of the event, in accordance with condition 91.a.iii (unless the permittee makes alternative reporting arrangements, in advance, with the Administrator [see condition 91.a.iii]).

29.c.v.  The permittee shall keep the written startup, shutdown, and malfunction plan on record after it is developed to be made available for inspection, upon request, by the Administrator for the life of the affected source or until the affected source is no longer subject to the provisions 40 CFR part 63. In addition, if the startup, shutdown, and malfunction plan is revised, the permittee shall keep previous (i.e., superseded) versions of the startup, shutdown, and malfunction plan on record, to be made available for inspection, upon request, by the Administrator, for a period of 5 years after each revision to the plan.

29.c.vi.  To satisfy the requirement to develop a startup, shutdown, and malfunction plan, the permittee may use the affected source’s standard operating procedures (SOP) manual, or an Occupational Safety and Health Administration (OSHA) or other plan, provided the alternative plans meet all the requirements and are made available for inspection when requested by the Administrator.

29.c.vii.  Based on the results of a determination made under condition 29.a.iii, the Administrator may require that the permittee make changes to the startup, shutdown, and malfunction plan for that source. The Administrator may require reasonable revisions to a startup, shutdown, and malfunction plan, if the Administrator finds that the plan:

29.c.vii.1.  Does not address a startup, shutdown, or malfunction event that has occurred;

29.c.vii.2.  Fails to provide for the operation of the source (including associated air pollution control equipment) during a startup, shutdown, or malfunction event in a manner consistent with good air pollution control practices for minimizing emissions at least to the levels required by conditions 26, 27, 28, and 29; or

29.c.vii.3.  Does not provide adequate procedures for correcting malfunctioning process and/or air pollution control equipment as quickly as practicable.

29.c.viii.  If the startup, shutdown, and malfunction plan fails to address or inadequately addresses an event that meets the characteristics of a malfunction but was not included in the startup, shutdown, and malfunction plan at the time the permittee developed the plan, the permittee shall revise the startup, shutdown, and malfunction plan within 45 days after the event to include detailed procedures for operating and maintaining the source during similar malfunction events and a program of corrective action for similar malfunctions of process or air pollution control equipment.

65.d.ii.  An approved alternative requirement must include a test schedule and the method to be used to measure emissions for performance tests.

65.d.iii.  Receiving approval of an alternative sampling frequency under 40 CFR 60.194 is deemed to have approval of the alternative sampling frequency under 40 CFR part 63 subpart LL.

65.d.iv.  If emissions in excess of the applicable TF limit occur while performing quarterly sampling approved under condition 65.d.i.1, the permittee shall return to monthly sampling for at least 12 months and may reduce to quarterly sampling when:

65.d.iv.1.  The average of all tests performed over the most recent 24- month period does not exceed 60 percent of the applicable limit, and

65.d.iv.2.  No more than one monthly performance test in the most recent 24-month period exceeds 75 percent of the applicable limit.

65.d.v.  If emissions in excess of the applicable TF limit occur while performing quarterly sampling approved under condition 65.d.i.2, the permittee shall immediately return to the monthly sampling schedule required by condition 65.a until another request for an alternative sampling frequency is approved by the applicable regulatory authority.

90.c.v.  An analysis demonstrating whether the affected source is a major source or an area source (using the emissions data generated for this notification);

90.c.vi.  A description of the air pollution control equipment (or method) for each emission point, including each control device (or method) for each hazardous air pollutant and the control efficiency (percent) for each control device (or method); and

90.c.vii.  A statement by the permittee as to whether each affected source has complied with the relevant standard or other requirements.

90.d.  If the permittee submits estimates or preliminary information in the application for approval of construction or reconstruction required in 40 CFR 63.5(d) in place of the actual emissions data or control efficiencies required in 40 CFR 63.5(d)(1)(ii)(H) and (d)(2), the permittee shall submit the actual emissions data and other correct information as soon as available but no later than with the notification of initial compliance status. [40 CFR 63.9(h)(5)]

90.e.  The permittee shall submit a one-time notification for each affected source of the intent to use an HF continuous emission monitor. [40 CFR 63.850(a)(7)]

90.f.  Notification of compliance approach. [40 CFR 63.850(a)(8)] The permittee shall develop and submit to the applicable regulatory authority, if requested, an engineering plan that describes the techniques that will be used to address the capture efficiency of the reduction cells for gaseous hazardous air pollutants in compliance with the emission limits in conditions 27 and 28.

90.g.  Change in information already provided. [40 CFR 63.9(j)] Any change in the information already provided under this condition 90 shall be provided to the Administrator in writing within 15 calendar days after the change.

91.  NESHAP Reporting requirements. Until a waiver of a reporting requirement has been granted by the Administrator under 40 CFR 63.10(f), the permittee of an affected source remains subject to the requirements of condition 91.

91.a.  Reporting requirements under the NESHAP General Provisions. [40 CFR 63.10(d)]

91.a.i.  Progress reports. If required to submit progress reports for an affected source as a condition of receiving an extension of compliance under 40 CFR 63.6(i), the permittee shall submit such reports to the Administrator (or the State with an approved permit program) by the dates specified in the written extension of compliance.

91.a.ii.  Periodic startup, shutdown, and malfunction reports. If actions taken by the permittee during a startup, shutdown, or malfunction of an affected source (including actions taken to correct a malfunction) are consistent with the procedures specified in the source’s startup, shutdown, and malfunction plan [see condition 29.c], the permittee shall state such information in a startup, shutdown, and malfunction report. Reports shall only be required if a startup, shutdown, or malfunction occurred during the reporting period. The startup, shutdown, and malfunction report shall consist of a letter, containing the name, title, and signature of the permittee or other responsible official who is certifying its accuracy, that shall be submitted to the Administrator semiannually (or on a more frequent basis if specified otherwise in a relevant standard or as established otherwise by the permitting authority in the source’s title V permit). The startup, shutdown, and malfunction report shall be delivered or postmarked by the 30th day following the end of each calendar half (or other calendar reporting period, as appropriate). If the permittee is required to submit excess emissions and continuous monitoring system performance (or other periodic) reports under this part, the startup, shutdown, and malfunction reports required under this condition may be submitted simultaneously with the excess emissions and continuous monitoring system performance (or other) reports. If startup, shutdown, and malfunction reports are submitted with excess emissions and continuous monitoring system performance (or other periodic) reports, and the permittee receives approval to reduce the frequency of reporting for the latter under condition 40 CFR 63.10(e), the frequency of reporting for the startup, shutdown, and malfunction reports also may be reduced if the Administrator does not object to the intended change. The procedures to implement the allowance in the preceding sentence shall be the same as the procedures specified in condition 40 CFR 63.10(e)(3).

91.a.iii.  Immediate startup, shutdown, and malfunction reports. Notwithstanding the allowance to reduce the frequency of reporting for periodic startup, shutdown, and malfunction reports under condition 91.a.ii, any time an action taken by the permittee during a startup, shutdown, or malfunction (including actions taken to correct a malfunction) is not consistent with the procedures specified in the affected source’s startup, shutdown, and malfunction plan, the permittee shall report the actions taken for that event within 2 working days after commencing actions inconsistent with the plan followed by a letter within 7 working days after the end of the event. The immediate report required under this condition shall consist of a telephone call (or facsimile [FAX] transmission) to the Administrator within 2 working days after commencing actions inconsistent with the plan, and it shall be followed by a letter, delivered or postmarked within 7 working days after the end of the event, that contains the name, title, and signature of the owner or operator or other responsible official who is certifying its accuracy, explaining the circumstances of the event, the reasons for not following the startup, shutdown, and malfunction plan, and whether any excess emissions and/or parameter monitoring exceedances are believed to have occurred. Notwithstanding the requirements of the previous sentence, after the effective date of an approved permit program in the State in which an affected source is located, the permittee may make alternative reporting arrangements, in advance, with the permitting authority in that State. Procedures governing the arrangement of alternative reporting requirements under this condition are specified in 40 CFR 63.9(i).

91.b.  Additional reporting requirements for sources with continuous monitoring systems.

91.b.i.  General. When more than one CEMS is used to measure the emissions from one affected source (e.g., multiple breechings, multiple outlets), the permittee shall report the results as required for each CEMS.

91.b.ii.  Excess emissions report. As required by 40 CFR 63.10(e)(3), the permittee shall submit a report (or a summary report) if measured emissions are in excess of the applicable standard. The report shall contain the information specified in 40 CFR 63.10(e)(3)(v) and be submitted semiannually unless quarterly reports are required as a result of excess emissions.

Reporting requirements under the Primary Aluminum Reduction NESHAP

91.c.  Performance test reports. The permittee shall report the results of the initial performance test as part of the notification of initial compliance status required in condition 90.c. Except as provided in condition 91.b.ii, the permittee shall submit a summary of all subsequent performance tests to the applicable regulatory authority on an annual basis. [40 CFR 63.850(b)]

91.d.  Startup, shutdown, and malfunction plan and reports. The permittee shall develop and implement a written plan as described in condition 29.c that contains specific procedures to be followed for operating the source and maintaining the source during periods of startup, shutdown, and malfunction and a program of corrective action for malfunctioning process and control systems used to comply with the standard. The plan does not have to be submitted with the permit application or included in the operating permit. The permitting authority may review the plan upon request. In addition to the information required condition 29.c, the plan shall include:

91.d.i.  Procedures, including corrective actions, to be followed if a monitoring device measures an operating parameter outside the limit(s) established under condition 46.f, if visible emissions from an exhaust stack indicating abnormal operation of a control device are observed by the permittee during the daily inspection required in condition 65.f, and

91.d.ii.  The permittee shall also keep records of each event as required by condition 82.a and record and report, as required in conditions 91.a.ii and 91.a.iii, if an action taken during a startup, shutdown, or malfunction is not consistent with the procedures in the plan as described in condition 29.c.iv.
