(c) The opacity standards set forth in this chapter shall apply at all times except during periods of startup, shutdown, malfunction, and as otherwise provided in the applicable standard.

(d) At all times, including periods of startup, shutdown, and malfunction, owners and operators shall, to the extent practicable, maintain and operate any affected facility including associated air pollution control equipment in a manner consistent with good air pollution control practice for minimizing emissions. Determination of whether acceptable operating and maintenance procedures are being used will be based on information available to the Technical Secretary which may include, but is not limited to, monitoring results, opacity observations, review of operating and maintenance procedures, and inspection of the source.

(e)

1. An owner or operator of an affected facility may request the Technical Secretary to determine opacity of emissions from the affected facility during the initial performance tests required by paragraph 1200-03-16-.01(5).

2. Upon receipt from such owner or operator of the written report of the results of the performance test required by paragraph 1200-03-16-.01(5), the Technical Secretary will make a finding concerning compliance with opacity and other applicable standards. If the Technical Secretary finds that an affected facility is in compliance with all applicable standards for which performance tests are conducted in accordance with paragraph 1200-03-16-.01(5) but during the time such performance tests are being conducted fails to meet any applicable opacity standards, he shall notify the owner or operator and advise him that he may petition the Technical Secretary within 10 days of receipt of notification to make appropriate adjustment to the opacity standard for the affected facility.

3. The Technical Secretary will grant such a petition upon a demonstration by the owner or operator that the affected facility and associated air pollution control equipment was operated and maintained in a manner to minimize the opacity of emissions during the performance tests; that the performance tests were performed under conditions established by the Technical Secretary; and that the affected facility and associated air pollution control equipment were incapable of being adjusted or operated to meet the applicable opacity standard.

4. The Technical Secretary will establish an opacity standard for the affected facility meeting the above requirements at a level at which the source will be able, as indicated by the performance and opacity tests, to meet the opacity standard at all times during which the source is meeting the mass or concentration emission standard.

(7) Notification and Record Keeping

(a) Any owner or operator subject to the provisions of this chapter shall furnish the Technical Secretary written notification as follows:

(c) It shall be demonstrated that the continuous in-stack opacity monitoring system meets the specifications in Performance Specification 1 as referenced in subparagraph (a) above, before the performance test required under paragraph (5) of this rule is conducted. Other continuous emission monitoring systems shall be evaluated during any performance tests required under paragraph (5) of this rule or within 30 days thereafter. The owner or operator of an affected facility shall conduct continuous emission monitoring system performance evaluations at such other times as may be required by the Technical Secretary and shall furnish the Technical Secretary within 60 days thereof two or, upon request, more copies of a written report of the results of all tests referenced in this subparagraph. These continuous monitoring system performance evaluations shall be conducted in accordance with the requirements and procedures contained in the applicable performance specification as referenced in subparagraph (a) above.

(d) Owners or operators of all continuous emission monitoring systems installed in accordance with the provisions of this chapter shall check the zero and span calibration drifts at least once daily in accordance with the method prescribed by the manufacturer of such systems unless the manufacturer recommends adjustments at shorter intervals, in which case such recommendations shall be followed. The zero and span shall, as a minimum, be adjusted whenever the 24-hour zero drift or 24-hour span drift limits of the applicable performance specifications as referenced in subparagraph (a) above are exceeded. For continuous monitoring systems measuring opacity of emissions, the optical surfaces exposed to the effluent gases shall be cleaned prior to performing the zero or span drift adjustments except that for systems using automatic zero adjustments, the optical surfaces shall be cleaned when the cumulative automatic zero compensation exceeds four percent opacity. Unless otherwise approved by the Technical Secretary, the following procedures, as applicable, shall be followed.

1. For extractive continuous monitoring systems measuring gases, minimum procedures shall include introducing applicable zero and span gas mixtures into the measurement system as near the probe as is practical. Span and zero gases certified by their manufacturer to be traceable to National Bureau of Standards reference gases shall be used whenever these reference gases are available. The span and zero gas mixtures shall be the same composition as specified in the applicable performance specification as referenced in subparagraph (a) above. Every six months from date of manufacture, span and zero gases shall be reanalyzed by conducting triplicate analyses with Reference Method 6, as referenced by Part 1200-03-16-.01(5)(g) 6., for sulfur dioxide; Reference Method 7, as referenced by Part 1200-03-16-.01(5)(g) 7., for nitrogen oxides; and Reference Method 3, as referenced by Part 1200-03-16-.01(5)(g) 3., for oxygen and carbon dioxide.

The gases may be analyzed at less frequent intervals if longer shelf lives are guaranteed by the manufacturer.

2. For non-extractive continuous monitoring systems measuring gases, minimum procedures shall include upscale check(s) using a certified calibration gas cell or test cell which is functionally equivalent to a known gas concentration. The zero check may be performed by computing the zero value from upscale measurements or by mechanically producing a zero condition.

3. For continuous monitoring systems measuring opacity of emissions, minimum procedures shall include a method for producing a simulated zero opacity condition and an upscale (span) opacity condition using a certified neutral density filter or other related technique to produce a known obscuration of the light beam. Such procedures shall provide a system check of the analyzer internal optical surfaces and all electronic circuitry including the lamp and photodetector assembly.

(e) Except for zero and span adjustments required under subparagraph (d) of this paragraph and system breakdowns, repairs, and calibration checks, all continuous monitoring systems shall be in continuous operation and shall meet minimum frequency of operation requirements as follows:

1. All continuous monitoring systems referenced by subparagraph (8)(c) for measuring opacity of emissions shall complete a minimum of one cycle of sampling and analyzing for each successive 10-second period and one cycle of data recording for each successive 6-minute period.

2. All continuous monitoring systems referenced by subparagraph (c) of this paragraph for measuring emissions, except opacity, shall complete a minimum of one cycle of operation (sampling, analyzing, and data recording) for each successive 15-minute period.

(f) All continuous monitoring systems or monitoring devices shall be installed in such a manner that representative measurements of emissions or process parameters from the affected facility are obtained. Additional procedures for location of continuous monitoring systems contained in the applicable performance specifications are referenced in subparagraph (8)(a) of this rule.

(g) When the effluents from a single affected facility or two or more affected facilities subject to the same emission standards are combined before being released to the atmosphere, the owner or operator may install applicable continuous monitoring systems on each effluent or on the combined effluent. When the affected facilities are not subject to the same emission standards, separate continuous monitoring systems shall be installed on each effluent. When the effluent from one affected facility is released to the atmosphere through more than one point, the owner or operator shall install applicable continuous monitoring systems on each separate effluent unless the installation of fewer systems is approved by the Technical Secretary.

(h)

1. Owners or operators of all continuous monitoring systems for measurement of opacity shall reduce all data to six- minute averages and for systems other than opacity to one- hour averages for time periods as defined in paragraph (4) of this Rule. Six minute opacity averages shall be calculated from 24 or more data points equally spaced over each six-minute period. For systems other than opacity, one-hour averages shall be computed from four or more data points equally spaced over each one-hour period. Data recorded during periods of system breakdowns, repairs, calibration checks, and zero and span adjustments shall not be included in the data averages computed under this subparagraph. An arithmetic or integrated average of all data may be used. The data output of all continuous monitoring systems may be recorded in reduced or nonreduced form (e.g., ppm pollutant and percent 02 or ng/J (lb/million Btu) of pollutant). All excess emissions shall be converted into units of the standard using the applicable conversion procedures specified in the rules of this chapter. After conversion into units of the standard, the data may be rounded to the same number of significant digits used in the following rules in this chapter to specify the applicable standard (e.g., rounded to the nearest one percent opacity).

2. Upon written application by an owner or operator, the Technical Secretary may approve alternatives to any monitoring procedures or requirements of this chapter including, but not limited to the following:

(i) Alternative monitoring requirements when installation of a continuous monitoring system or monitoring device specified by this chapter would not provide accurate measurements due to liquid water or other interferences caused by substances with the effluent gases.

(ii) Alternative monitoring requirements when the affected facility is infrequently operated.

(iii) Alternative monitoring requirements to accommodate continuous monitoring systems that require additional measurements to correct for stack moisture conditions.

(iv) Alternative locations for installing continuous monitoring systems or monitoring devices when the owner or operator can demonstrate that installation at alternative locations will enable accurate and representative measurements.

(v) Alternative methods of converting pollutant concentration measurements to units of the standards.

(vi) Alternative procedures for performing daily checks of zero and span drift that do not involve use of span gases or test cells.

(vii) Alternative to the A.S.T.M. test methods or sampling procedures specified by any rule. (Note: All references to ASTM in this rule refers to the American Society for Testing Materials. Copies of methods are available for purchase by writing to ASTM, 1916 Race Street, Philadelphia, PA 19103 or by writing to the Tennessee Division of Air Pollution Control, 701 Broadway, 4th Floor Customs House, Nashville, TN 37219. Be sure and specify which method is desired).

(viii) Alternative continuous monitoring systems that do not meet the design or performance requirements in Performance Specification 1, as referenced in subparagraph (a) above, but adequately demonstrate a definite and consistent relationship between its measurements and the measurements of opacity by a system complying with the requirements in Performance Specification 1. The Technical Secretary may require that such demonstration be performed for each affected facility.

(ix) Alternative monitoring requirements when the effluent from a single affected facility or the combined effluent from two or more affected facilities are released to the atmosphere through more than one point.

(i) The reference methods for continuous monitoring systems for opacity, sulfur dioxide, nitrogen oxides, oxygen, and carbon dioxide are found in the Federal Register, Vol. 40, No. 194, of October 6, 1975.

(a) Modification

1. Modification as defined and used in this chapter shall have a less inclusive meaning than in the other chapters of these regulations. Therefore, an action not considered a modification for inclusion under the requirements of this chapter may be a modification as regards the permit requirements in chapter 1200-03-09 and other requirements for new and/or modified sources in other than this chapter 1200-03-16 of the regulations.

2. Except as provided under parts 5. and 6. of this subparagraph and subparagraph (b) of this paragraph, any physical or operational change to an existing facility which results in an increase in the emission rate to the atmosphere of any pollutant to which a standard applies shall be considered a modification within the meaning of this chapter. Upon modification, an existing facility shall become an affected facility for each pollutant to which a standard applies and for which there is an increase in the emission rate to the atmosphere.

3. Emission rate shall be expressed as kg/hr of any pollutant discharged into the atmosphere for which a standard is applicable. The Technical Secretary shall use the following to determine emission rate:

(i) Emission factors are specified in the latest issue of "Compilation of Air Pollution Emission Factors," EPA Publication No. AP-42, or other emission factors determined by the Technical Secretary to be superior to AP-42 emission factors, in cases where utilization of emission factors demonstrate that the emission level resulting from the physical or operational change will either clearly increase or not increase.

(ii) Material balances, continuous monitor data, or manual emission tests in cases where utilization of emission factors as referenced in subpart (i) of this part does not demonstrate to the Technical Secretary's satisfaction whether the emission level resulting from the physical or operational change will either clearly increase or clearly not increase, or where an owner or operator demonstrates to the Technical Secretary's satisfaction that there are reasonable grounds to dispute the results obtained by the Technical Secretary utilizing emission factors as referenced in subpart (i) of this part. When the emission rate is based on results from manual emission tests or continuous monitoring systems, the procedures specified in Appendix C as listed in the Federal Register (40 FR 58420, December 16, 1975) shall be used to determine whether an increase in emission rate has occurred. Tests shall be conducted under such conditions as the Technical Secretary shall specify to the owner or operator based on representative performance of the facility. At least three valid test runs must be conducted before and at least three after the physical or operational change. All operating parameters which may affect emissions must be held constant to the maximum feasible degree for all test runs.

4. The addition of an affected facility to a stationary source as an expansion to that source or as a replacement for an existing facility shall not by itself bring within the applicability of this chapter any other facility within that source.

5.

(i) A modification shall not be deemed to occur if an existing facility undergoes a physical or operational change where the owner or operator demonstrates to the Technical Secretary's satisfaction (by any of the procedures prescribed under part 3. of this subparagraph) that the total emission rate of any pollutant has not increased from all facilities within the stationary source to which appropriate reference, equivalent, or alternative methods can be applied. An owner or operator may completely and permanently close any facility within a stationary source to prevent an increase in the total emission rate regardless of whether such reference, equivalent or alternative method can be applied, if the decrease in emission rate from such closure can be adequately determined by any of the procedures prescribed under part 3. of this subparagraph. The owner or operator of the source shall have the burden of demonstrating compliance with this paragraph.

(ii) Such demonstration shall be in writing and shall include:

(I) The name and address of the owner or operator.

(II) The location of the stationary source.

(III) A complete description of the existing facility undergoing the physical or operational change resulting in an increase in emission rate, any applicable control system, and the physical or operational change to such facility.

(IV) The emission rates into the atmosphere from the existing facility of each pollutant to which a standard applies physical or operational change takes place, to the extent such information is known or can be predicted.

(V) A complete description of each facility and the control systems, if any, for those facilities within the stationary source where the emission rate of each pollutant in question will be decreased to compensate for the increase in emission rate from the existing facility undergoing the physical or operational change.

(VI) The emission rates into the atmosphere of the pollutants in question from each facility described under item (V) of this subpart both before and after the improvement or installation of any applicable control system or any physical or operational changes to such facilities to reduce emission rate.

(VII) A complete description of the procedures and methods used to determine the emission rates.

(iii) Compliance with part 5. of this subparagraph may be demonstrated by the methods listed in part 3. of this subparagraph where appropriate. Decreases in emissions resulting from requirements of rules in other chapters of Tennessee Air Pollution Control Regulations will not be acceptable. The required reduction in emission rate may be accomplished through the installation or improvement of a control system or through physical or operational changes to facilities including reducing the production of a facility or closing a facility.

(iv) Emission rates established for the existing facility which is undergoing a physical or operational change resulting in an increase in the emission rate, and established for the facilities described under item 5.(ii)(V) of this subparagraph shall become the baseline for determining whether such facilities undergo a modification or are in compliance with standards.

(v) Any emission rate in excess of that rate established under subpart (iv) of this part shall be a violation of these regulations except as otherwise provided in part 6. of this subparagraph. However, any owner or operator electing to demonstrate compliance under this part 5. must apply to the Technical Secretary to obtain the use of any exemptions under subparts 6.(i), 6.(ii), and 6.(iv) of this subparagraph. The Technical Secretary will grant such under this paragraph will not be circumvented or nullified by the utilization of the exemption.

(vi) The Technical Secretary may require the use of continuous monitoring devices and compliance with necessary reporting procedures for each facility described in items 5.(ii)(III) and 5.(ii)(V) of this subparagraph.

6. The following shall not, by themselves, be considered modifications under this chapter:

(i) Maintenance, repair, and replacement which the Technical Secretary determines to be routine for a source category, subject to the provisions of part 4. of this subparagraph and subparagraph (b) of this paragraph.

(ii) An increase in production rate of an existing facility, if that increase can be accomplished without a capital expenditure on the stationary source containing that facility.

(iii) An increase in the hours of operation.

(iv) Use of an alternative fuel or raw material if, prior to the date any standard under this part becomes applicable to that source type, provided the existing facility was designed to accommodate that alternative use. A facility shall be considered to be designed to accommodate an alternative fuel or raw material if that use could be accomplished under the facility's construction specifications, as amended, prior to the change. Conversion to coal required for energy considerations, shall not be considered a modification.

(v) The addition or use of any system or device whose primary function is the reduction of air pollutants, except when an emission control system is removed or is replaced by a system which the Technical Secretary determines to be less environmentally beneficial.

(vi) The relocation or change in ownership of an existing facility.

7. Special provisions set forth under an applicable rule of this chapter shall supersede any conflicting provisions of this paragraph.

8. Within 180 days of the completion of any physical or operational change subject to the control measures specified in parts 2. or 5. of this subparagraph, compliance with all applicable standards must be achieved.

(b) Reconstruction.

1. An existing facility, upon reconstruction, becomes an affected facility, irrespective of any change in emission rate.

2. "Reconstruction" means the replacement of components of an existing facility to such an extent that:

(i) The fixed capital cost of the new components exceeds 50 percent of the fixed capital cost that would be required to construct a comparable entirely new facility, and

(ii) It is technologically and economically feasible to meet the applicable standards set forth in this chapter.

3. "Fixed capital cost" means the capital needed to provide all the depreciable components.

4. If an owner or operator of an existing facility proposes to replace components, and the fixed capital cost of the new components exceeds 50 percent of the fixed capital cost that would be required to construct a comparable entirely new facility, he shall notify the Technical Secretary of the proposed replacements. The notice must be postmarked 60 days (or as soon as practicable) before construction of the replacements is commenced and must include the following information:

(i) Name and address of the owner or operator.

(ii) The location of the existing facility.

(iii) A brief description of the existing facility and the components which are to be replaced.

(iv) A description of the existing air pollution control equipment and the proposed air pollution control equipment.

(v) An estimate of the fixed capital cost of the replacements and of constructing a comparable entirely new facility.

(vi) The estimated life of the existing facility after the replacements.

(vii) A discussion of any economic or technical limitations the facility may have in complying with the applicable standards of performance after the proposed replacements.

5. The Technical Secretary will determine, within a reasonable time after receipt of the notice required by part 4. of this subparagraph and any additional information he may reasonably require, whether the proposed replacement constitutes reconstruction.

6. The Technical Secretary's determination under part 5. of this subparagraph shall be based on:

(i) The fixed capital cost of the replacements in comparison to the fixed capital cost that would be required to construct a comparable entirely new facility;

(ii) The estimated life of the facility after the replacements compared to the life of a comparable entirely new facility;

(iii) The extent to which the components being replaced cause or contribute to the emissions from the facility; and

(iv) Any economic or technical limitations on compliance with applicable standards of performance which are inherent in the proposed replacements.

7. Individual rules of this chapter may include specific provisions which refine and delimit the concept of reconstruction set forth in this subparagraph.

(10) Upon mutual agreement of the owner or operator of any air contaminant source and the Technical Secretary, an emission limit more restrictive than that otherwise specified in this Chapter may be established. This emission limit shall be stated as a special condition for any permit or order issued concerning the source. Violation of this agreed to, more stringent emission standard is grounds for revocation of the issued permit and/or other enforcement measures provided for in the Tennessee Air Quality Act.

(11) General Control Device Requirements
