(a) Using that portion of a stack which exceeds good engineering practice stack height;
(b) Varying the rate of emission of a pollutant according to atmospheric conditions or ambient concentrations of that pollutant; or
(c) Increasing final exhaust gas plume rise by manipulating source process parameters, exhaust gas parameters or stack parameters, combining exhaust gases from several existing stacks into one stack or other selective handling of exhaust gas streams so as to increase the exhaust gas plume rise.
2. The term does not include:
(a) The reheating of a gas stream, following use of a pollution control system, for the purpose of returning the gas to the temperature at which it was originally discharged from the facility generating the gas stream.
(b) The merging of exhaust gas streams where:

Notes:
Note A: The Director shall use the state standards in considering whether to issue a permit for a stationary source and shall ensure that the stationary source will not cause the state standards to be exceeded in areas where the general public has access. For the 2006 particulate matter as PM2.5 24-hour and annual standards, the 2010 nitrogen dioxide 1-hour standard and the 2010 sulfur dioxide 1-hour standard, the Director shall use the form of the standards set forth in 40 C.F.R. §§ 50.11, 50.13 and 50.17, as those provisions existed on June 23, 2014, to ensure that the state standard is no more stringent than the national ambient air quality standard in determining whether the stationary source will comply with the state standards in areas where the general public has access.
Note B: National ambient air quality standards are used in determinations of attainment or nonattainment. The form of a national ambient air quality standard is the criteria which must be satisfied for each respective concentration level of a standard for the purposes of attainment. The form for each national ambient air quality standard is set forth in 40 C.F.R. Part 50 and may be viewed at http://www.epa.gov/criteria-air-pollutants/naaqs-table. National primary standards are the levels of air quality necessary, with an adequate margin of safety, to protect the public health. National secondary standards are the levels of air quality necessary to protect the public welfare from any known or anticipated adverse effects of a regulated air pollutant.
Note C: Where applicable, concentration is expressed first in units in which it was adopted. Measurements of air quality that are expressed as mass per unit volume, such as micrograms per cubic meter, must be corrected to a reference temperature of 25 degrees Centigrade and a reference pressure of 760 mm of Hg (1,013.2 millibars), except measurements of particulate matter as PM2.5 and lead (Pb), which are calculated in micrograms per cubic meter at local conditions; “ppb” in this table refers to parts per billion by volume, or nanomoles of regulated air pollutant per mole of gas; “ppm” refers to parts per million by volume, or micromoles of regulated air pollutant per mole of gas; “µg/m3” refers to micrograms per cubic meter.
Note D: Any reference method or equivalent method designated in accordance with 40 C.F.R. Part 53 may be used to measure a regulated air pollutant.
Note E: The state ambient air quality standard for hydrogen sulfide does not include naturally occurring background concentrations.
2. The state standards of quality for ambient air are minimum goals, and it is the intent of the Commission in this section to protect the existing quality of Nevada’s air to the extent that it is economically and technically feasible.

(b) Material balances, data from continuous monitors, or manual tests for emission in cases where the use of factors of emission does not demonstrate to the Director’s satisfaction whether the level of emission resulting from the physical or operational change will either clearly increase or clearly not increase, or where an owner or operator demonstrates to the Director’s satisfaction that there are reasonable grounds to dispute the result obtained by the Director using factors of emission.
2. When the rate of emission is based on results from manual tests for emission or systems for continuous observation, the procedures specified in Appendix C of 40 C.F.R. § 60 must be used to determine whether an increase in the rate of emission has occurred. Tests must be conducted under such conditions as the Director specifies to the owner or operator based on the representative performance of the facility. At least three valid tests 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 each running of a test.

1. Maintenance, repair and replacement which the Director determines to be routine for a source category, subject to NAC 445B.247.
2. An increase in the production rate of an existing facility, if that increase can be accomplished without a capital expenditure on the stationary source containing that facility, unless the change would be prohibited by an enforceable restriction on the permit.
3. An increase in the hours of operation, unless the change would be prohibited by an enforceable restriction on the permit.
4. Use of an alternative fuel or raw material if, before the date any standard under NAC 445B.235 to 445B.250, inclusive, becomes applicable to that source type, the existing facility was designed to accommodate that alternative use. A facility is 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, before the change. Conversion to coal required for energy considerations, as specified in section 119(d)(5) of the Act, is not considered a modification.
5. The addition or use of any system or device whose primary function is the reduction of regulated air pollutants, except when an emission control system is removed or is replaced by a system which the Director determines to be less environmentally beneficial.
6. The relocation or change in ownership of an existing facility.

NAC 445B.252 Testing and sampling. (NRS 445B.210, 445B.225, 445B.300)
1. To determine compliance with NAC 445B.001 to 445B.390, inclusive, before the approval or the continuance of an operating permit or similar class of permits, the Director may either conduct or order the owner of any stationary source to conduct or have conducted such testing and sampling as the Director determines necessary. Testing and sampling or either of them must be conducted and the results submitted to the Director within 60 days after achieving the maximum rate of production at which the affected facility will be operated, but not later than 180 days after initial start-up of the facility and at such other times as may be required by the Director.
2. Tests of performance must be conducted and data reduced in accordance with the methods and procedures of the test contained in each applicable subsection of this section unless the Director:
(a) Specifies or approves, in specific cases, the use of a reference method with minor changes in methodology;
(b) Approves the use of an equivalent method;
(c) Approves the use of an alternative method, the results of which the Director has determined to be adequate for indicating whether a specific stationary source is in compliance; or
(d) Waives the requirement for tests of performance because the owner or operator of a stationary source has demonstrated by other means to the Director’s satisfaction that the affected facility is in compliance with the standard.
3. Tests of performance must be conducted under such conditions as the Director specifies to the operator of the plant based on representative performance of the affected facility. The owner or operator shall make available to the Director such records as may be necessary to determine the conditions of the test of performance. Operations during periods of start-up, shutdown and malfunction must not constitute representative conditions of a test of performance unless otherwise specified in the applicable standard.
4. The owner or operator of an affected facility shall give notice to the Director 30 days before the test of performance to allow the Director to have an observer present. A written testing procedure for the test of performance must be submitted to the Director at least 30 days before the test of performance to allow the Director to review the proposed testing procedures.
5. Each test of performance must consist of at least three separate runs using the applicable method for that test. Each run must be conducted for the time and under the conditions specified in the applicable standard. For the purpose of determining compliance with an applicable standard, the arithmetic means of results of the runs apply. In the event of forced shutdown, failure of an irreplaceable portion of the sampling train, extreme meteorological conditions or other circumstances with less than three valid samples being obtained, compliance may be determined using the arithmetic mean of the results of the other two runs upon the Director’s approval.
6. All testing and sampling will be performed in accordance with recognized methods and as specified by the Director.
7. The cost of all testing and sampling and the cost of all sampling holes, scaffolding, electric power and other pertinent allied facilities as may be required and specified in writing by the Director must be provided and paid for by the owner of the stationary source.

1. For continuous monitoring systems measuring opacity of emissions, the optical surfaces exposed to the effluent gases must be cleaned before performing the zero or span drift adjustments, except that for systems using automatic zero adjustments, the optical surfaces must be cleaned when the cumulative automatic zero compensation exceeds 4 percent opacity. Unless otherwise approved by the Director, the following procedures, as applicable, must be followed:
(a) For extractive continuous monitoring systems measuring gases, minimum procedures must 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 Institute of Standards and Technology reference gases must be used whenever these reference gases are available. The span and zero gas mixtures must be the same composition as specified in Appendix B of 40 C.F.R. Part 60. Every 6 months after the date of manufacture, span and zero gases must be reanalyzed by conducting triplicate analyses with Reference Methods 6 for SO2, 7 for NO, and 3 for O2 and CO2, respectively. The gases may be analyzed at less frequent intervals if longer shelf lives are guaranteed by the manufacturer.
(b) For nonextractive continuous monitoring systems measuring gases, minimum procedures include upscale checks 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.
(c) For continuous monitoring systems measuring opacity of emissions, minimum procedures 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. These procedures must provide a system check of the analyzer internal optical surfaces and all electronic circuitry, including the lamp and photodetector assembly.

1. Except as otherwise provided in subsection 2 and in NAC 445B.288, an operating permit, operating permit to construct or permit to construct is required for each stationary source that is a Class I or Class II source and:
(a) If a stationary source is a Class I source:
(1) A revision of the operating permit or the permit to construct is required pursuant to the requirements of NAC 445B.3425, 445B.344 or 445B.3441 before the stationary source may be modified; or
(2) A revision of the operating permit to construct is required pursuant to the requirements of paragraph (a) of subsection 1 of NAC 445B.3361 before the stationary source may be modified,
Ê as appropriate.
(b) If a stationary source is a Class II source, a revision of the operating permit or the permit to construct is required pursuant to the requirements of NAC 445B.3465 before the stationary source may be modified.
(c) If a stationary source maintains one or more thermal units that emit mercury, the owner or operator of a thermal unit that emits mercury shall comply with the provisions set forth in NAC 445B.3611 to 445B.3689, inclusive.
2. A Class I source is not subject to the provisions of subparagraph (1) of paragraph (a) of subsection 1 if the source is not a major source, an affected source or a solid waste incineration unit required to obtain a permit pursuant to 42 U.S.C. § 7429(e). For a Class I source which is not a major source and which subsequently becomes subject to a standard or other requirement under 42 U.S.C. § 7411 or 7412, the Administrator will determine whether to exempt the source from the requirement to obtain a Class I operating permit at the time that the new standard is adopted.
3. An operating permit, operating permit to construct or permit to construct may not be transferred from one owner or piece of equipment to another. An owner or operator may apply for an administrative amendment reflecting a change of ownership or the name of the stationary source for the effective time remaining on the original operating permit pursuant to NAC 445B.319.

NAC 445B.288 Operating permits: Exemptions from requirements; insignificant activities. (NRS 445B.210, 445B.300)
1. The following categories of sources are not required to obtain an operating permit:
(a) A source that would otherwise be required to obtain an operating permit solely because it is subject to 40 C.F.R. Part 60, Subpart AAA, Standards of Performance for New Residential Wood Heaters.
(b) A source that would otherwise be required to obtain an operating permit solely because it is subject to 40 C.F.R. Part 61, Subpart M, National Emission Standard for Asbestos, section 61.145.
(c) Agricultural equipment used in the normal operation of a farm, other than agricultural equipment which is classified as, or located at, a source for which a permit is required under Title V of the Act or which is subject to any standard set forth in 40 C.F.R. Part 60 or 61.
2. The following emission units are considered to be insignificant activities unless the emission unit is otherwise subject to another specific applicable requirement, including, without limitation, any requirement or standard set forth in 40 C.F.R. Part 60, 61 or 63:
(a) Any equipment or other contrivance used exclusively for the processing of food for human consumption.
(b) An incinerator which has a rated burning capacity that is less than 25 pounds per hour.
(c) An emission unit that has a maximum allowable throughput or batch load rate of less than 50 pounds per hour, unless the emission unit directly emits, or has the potential to emit, a hazardous air pollutant.
(d) A storage container for petroleum liquid, or a storage facility for volatile organic liquid, that has a capacity of less than 40,000 gallons.
(e) Except as otherwise provided in paragraphs (f), (g) and (h), air-conditioning equipment or fuel-burning equipment that, individually, has a rating which is:
(1) Less than 4,000,000 Btu’s per hour; or
(2) Equal to or greater than 4,000,000 Btu’s per hour if the equipment operates less than 100 hours per calendar year.
(f) A portable internal combustion engine that has a rating for output which is:
(1) Less than 500 horsepower; or
(2) Equal to or greater than 500 horsepower if the engine operates less than 100 hours per calendar year.
(g) A stationary internal combustion engine that has a rating for output which is:
(1) Less than 250 horsepower; or
(2) Equal to or greater than 250 horsepower if the engine operates less than 100 hours per calendar year.
(h) An emergency generator. Except as otherwise provided in this paragraph, an emergency generator qualifies as an insignificant activity pursuant to this paragraph only if the emergency generator is an internal combustion engine that is used to generate electrical power to maintain essential operations during unplanned electrical power outages. An emergency generator that is owned or operated by a stationary source and whose potential to emit is calculated on the basis of less than 500 hours of operation does not qualify as an insignificant activity.
3. If an emission unit is considered an insignificant activity and is subject to a limitation on its hours of operation pursuant to subsection 2, the owner or operator of the emission unit shall maintain an operating log of the hours of operation of the emission unit. The operating log must be maintained at the site of the emission unit and made available to the Director upon his or her request. The owner or operator shall retain the operating log for not less than 5 years.
4. The Director may, upon written request, payment of the fee of $1,000 and a satisfactory demonstration by an applicant, approve an emission unit as an insignificant activity if the emission unit is not otherwise subject to another specific applicable requirement, including, without limitation, any requirement or standard set forth in 40 C.F.R. Part 60, 61 or 63. To be approved as an insignificant activity, an emission unit must meet the following criteria:
(a) The operation of the emission unit, not considering controls or limits on production, type of materials processed, combusted or stored, or hours of operation, will not result in:
(1) Emissions of a hazardous air pollutant that exceed 1 pound per hour or 1,000 pounds per year, as appropriate;
(2) Emissions of regulated air pollutants that exceed 4,000 pounds per year;
(3) Emissions of regulated air pollutants that exceed any other limitation on emissions pursuant to any other applicable requirement; or
(4) Emissions of regulated air pollutants that adversely impact public health or safety, or exceed any ambient air quality standards; and
(b) The emissions from the emission unit are not relied on to avoid any other applicable requirements.
Ê If there are multiple emission units, the Director may, after considering the impact of the combined emissions of multiple emission units, determine whether to approve one or more of the specific emission units as an insignificant activity.
5. Except as otherwise provided in NAC 445B.094, emissions from insignificant activities, as determined pursuant to this section, must be included in any determination of whether a stationary source is a major source.
6. A stationary source is not required to obtain an operating permit pursuant to NAC 445B.001 to 445B.390, inclusive, for emissions below the threshold for a Class II source as set forth in NAC 445B.037 or for any emission unit determined to be an insignificant activity in accordance with this section, as long as the stationary source is not otherwise subject to any other requirement to obtain an operating permit under Title V of the Act. Such an exclusion from the requirements relating to permitting is not an exclusion or exemption from any other requirement set forth in NAC 445B.001 to 445B.390, inclusive, relating to the operation of the emission unit determined to be an insignificant activity.
7. A stationary source which consists solely of insignificant activities as determined pursuant to this section and which is not otherwise subject to any other requirement to obtain an operating permit under Title V of the Act is not required to obtain an operating permit to operate as a stationary source. Such an exclusion from the requirements relating to permitting is not an exclusion or exemption from any other requirement set forth in NAC 445B.001 to 445B.390, inclusive, relating to the operation of the stationary source or any insignificant activity that is a part of the stationary source.
8. The provisions of this section do not apply to a thermal unit that emits mercury.
9. As used in this section, “thermal unit that emits mercury” has the meaning ascribed to it in NAC 445B.3643.

(Added to NAC by Environmental Comm’n, eff. 9-19-90; A 12-13-93, eff. 11-15-94; 10-30-95; R040-10, 7-22-2010)
NAC 445B.308 Prerequisites and conditions for issuance or revision of certain operating permits; compliance with applicable state implementation plan. (NRS 445B.210, 445B.300)
1. In any area designated as attainment or unclassifiable for a regulated air pollutant, before an operating permit or a revision of an operating permit may be issued:
(a) For a new or modified stationary source;
(b) For a plantwide applicability limitation; or
(c) To allow a plantwide applicability limitation to expire and not be renewed,
Ê in accordance with NAC 445B.308 to 445B.314, inclusive, the applicant must submit to the Director an environmental evaluation and any other information the Director determines is necessary to make an independent air quality impact assessment.
2. The Director shall not issue an operating permit or a revision of an operating permit for any stationary source if the environmental evaluation submitted by the applicant shows, or if the Director determines, in accordance with the provisions of this section, that the stationary source:
(a) Will prevent the attainment and maintenance of the state ambient air quality standards. For the purposes of this paragraph, only those state ambient air quality standards that have been established in NAC 445B.22097 need to be considered in the environmental evaluation.
(b) Will cause a violation of the applicable state implementation plan.
(c) Will cause a violation of any applicable requirement.
(d) Will not comply with subsection 4.
3. The Director shall not issue an operating permit or a revision of an operating permit for any stationary source if the Director determines, in accordance with subsection 3 of NAC 445B.311, that the degree of emission limitation required for control of an air pollutant under this section is affected by that amount of the stack height of any source as exceeds good engineering practice stack height, including a good engineering practice stack height demonstrated by a fluid model or a field study approved by the Director in accordance with paragraph (c) of subsection 1 of NAC 445B.083, or any other dispersion technique.
4. To be issued an operating permit or a revision of an operating permit, the owner or operator of a major stationary source or major modification, as those terms are defined in 40 C.F.R. § 51.165, who proposes to construct in an area designated nonattainment for the regulated air pollutant or pollutants for which the stationary source or modification is major must:
(a) Comply with the provisions of 40 C.F.R. § 51.165, as adopted by reference in NAC 445B.221.
(b) Adopt as an emission limitation for the stationary source the lowest achievable emission rate for each nonattainment regulated air pollutant from the stationary source.
(c) Demonstrate that all other stationary sources within this State which are owned, operated or controlled by the applicant are in compliance or on a schedule of compliance with NAC 445B.001 to 445B.390, inclusive, and all other applicable requirements and conditions of the permit.
(d) Conduct an analysis of any anticipated impact on visibility in any federal Class I area which may be caused by emissions from the stationary source.
(e) Conduct an analysis of alternative sites, sizes, processes of production and techniques for environmental control for the proposed stationary source. Except as otherwise provided in this paragraph, the analysis must demonstrate that the benefits of the proposed stationary source significantly outweigh the detrimental environmental and social effects that will result from its location, construction or modification. If the major stationary source or major modification proposes to locate in an area designated as marginal nonattainment for ozone, the analysis must demonstrate an offset ratio of 1.2 to 1 for volatile organic compounds and nitrogen oxides. For the purposes of this paragraph, a stationary source which is major for volatile organic compounds or nitrogen oxides shall be deemed major for ozone if the proposed location of the major stationary source or major modification is in an area designated as nonattainment for ozone.
(f) Comply with one of the following:
(1) Sufficient offsets in emissions must be obtained by the time the proposed stationary source begins operation to ensure that the total allowable emissions of each nonattainment regulated air pollutant from the existing stationary sources in the area, those stationary sources in the area which have received their respective permits and the proposed stationary source will be sufficiently less than the total emissions from the existing stationary sources and those stationary sources in the area which have received their respective permits before the proposed stationary source applies for its operating permit or a revision of an operating permit, in order to achieve reasonable further progress; or
(2) If the major stationary source or major modification is located in a zone identified by the Administrator as one to be targeted for economic development, the owner or operator must demonstrate that the emission from the stationary source will not cause or contribute to emissions levels which exceed the allowance permitted for a regulated air pollutant for the nonattainment area.
Ê For the purposes of this paragraph, offsets must comply with the provisions of Appendix S of 40 C.F.R. Part 51, as adopted by reference in NAC 445B.221, and be coordinated with the appropriate local agency for the control of air pollution.
5. To be issued an operating permit or a revision of an operating permit, the owner or operator of a major stationary source or major modification who proposes to construct in any area designated as attainment or unclassifiable under 42 U.S.C. § 7407(d) must comply with the provisions of 40 C.F.R. § 52.21, as adopted by reference in NAC 445B.221.
6. The Director may impose any reasonable conditions on his or her approval, including conditions requiring the owner or operator of the stationary source to:
(a) Conduct monitoring of the quality of the ambient air at the facility site for a reasonable period before the commencement of construction or modification and for any specified period after operation has begun at the stationary source; and
(b) Meet standards for emissions that are more stringent than those found in NAC 445B.001 to 445B.390, inclusive.
7. If a proposed stationary source located on contiguous property is constructed or modified in phases which individually are not subject to review as provided in NAC 445B.308 to 445B.314, inclusive, all phases occurring since November 7, 1975, must be added together for determining the applicability of those sections.
8. Approval and issuance of an operating permit or a revision of an operating permit for any stationary source does not affect the responsibilities of the owner or owners to comply with any other portion of the applicable state implementation plan.
9. As used in this section:
(a) “Offset ratio” means the percentage by which a reduction in an emission must exceed the corresponding increase in that emission.
(b) “Reasonable further progress” means the annual incremental reductions in emissions of the relevant regulated air pollutant that are required by 42 U.S.C. §§ 7501 to 7515, inclusive, or are required by the Administrator to ensure attainment of the applicable standard for national ambient air quality by the applicable date.

NAC 445B.3831 Requirements for issuance. (NRS 445B.210, 445B.300)
1. The Director shall not issue an emission reduction credit unless the following requirements are met:
(a) The emission reductions used to generate the emission reduction credit are surplus, permanent, quantifiable and federally enforceable.
(b) Except when a unit is fully shutdown, a revised federally enforceable operating permit has been issued which contains practicably enforceable conditions to limit the potential of the emission unit to emit the allowable emissions of the stationary source.
(c) The baseline for determining credit for emission reductions is the applicable state implementation plan emission limitation in effect at the time the application to construct or modify a source is filed, except that the baseline shall be the actual emissions of the emissions unit from which the emission reduction credit is obtained when:
(1) The demonstration of reasonable further progress and attainment of ambient air quality standards is based upon the actual emissions of sources located within a designated nonattainment area for which the preconstruction review program was adopted; or
(2) The applicable state implementation plan does not contain an emission limitation for that emissions unit.
(d) If the applicable state implementation plan requires certain equipment controls in lieu of an emission limitation, the baseline allowable emissions are based on continuous emissions monitoring system data, where available, or calculated using the actual operating conditions of the emission unit for the previous 2-year period in conjunction with the required equipment controls.
(e) The emission reduction credit has not been relied upon by the Director in issuing any permit under regulations approved pursuant to 40 C.F.R. §§ 51.160 to 51.166, inclusive, or in an attainment demonstration or reasonable further progress demonstration in a nonattainment area state implementation plan.
(f) If the stationary source is subject to both:
(1) An emission limitation established in a new source performance standard or a national emission standard for hazardous air pollutants under 42 U.S.C. §§ 7411 and 7412; and
(2) A different applicable state implementation plan limitation,
Ê the more stringent limitation is used as the baseline for determining the emission reduction credit. The difference in emissions between the applicable state implementation plan and the new source performance standard or national emission standard for hazardous air pollutants for the stationary source shall not be used as a basis for an emission reduction credit. If a stationary source is not subject to an emission limitation pursuant to a new source performance standard or national emission standard for hazardous air pollutants, an emission reduction credit may be issued if the stationary source accepts a federally enforceable emission limitation that is more stringent than an emission limitation under the applicable state implementation plan.
2. An emission reduction credit shall not be issued:
(a) If the emission limitation under the applicable state implementation plan allows for greater emissions than the uncontrolled emission rate of the source, for emissions above the uncontrolled emission rate.
(b) For existing actual emissions which exceed the allowable emissions specified in the source’s federally enforceable operating permit.
